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

83 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
85 Prefer POSIX timers if available.
86 They avoid a race if the timer is too close to the current time.
87 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
88 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

114 * w32.h (Vlibrary_cache): Do not declare.
116 2012-09-25 Eli Zaretskii <eliz@gnu.org>
118 * w32proc.c (sys_signal): Handle all signals defined by the
119 MS-Windows runtime, not just SIGCHLD. Actually install the signal
120 handlers for signals supported by Windows. Don't override
121 term_ntproc as the handler for SIGABRT.
122 (sigaction): Rewrite to call sys_signal instead of duplicating its
124 (sys_kill): Improve commentary.
126 * w32.c (term_ntproc): Accept (and ignore) one argument, for
127 consistency with a signature of a signal handler. All callers
129 (init_ntproc): Accept an argument DUMPING. If dumping, don't
130 install term_ntproc as a signal handler for SIGABRT, as that
131 should be done by the dumped Emacs.
133 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
135 * w32select.c (term_w32select): Protect against repeated
136 invocation by setting clipboard_owner to NULL after calling
139 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
140 and term_ntproc to their modified signatures.
142 * character.c (char_string, string_char): Remove calls to
143 MAYBE_UNIFY_CHAR. See the discussion starting at

154 when encountering an unknown bytecode.
156 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
158 image.c, indent.c: Use bool for booleans.
159 * dispextern.h (struct image_type): Members valid_p, load, init
160 now return bool, not int. All uses changed.
161 * image.c: Omit unnecessary static decls.
162 (x_create_bitmap_mask, x_build_heuristic_mask):
163 Return void, not int, since callers don't care about the return value.

198 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
200 Move pid_t related decls out of lisp.h.
201 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
202 (interruptible_wait_for_termination):
203 Move these decls from lisp.h to syswait.h, since they use pid_t.
204 Needed on FreeBSD; see Herbert J. Skuhra in
205 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
206 * callproc.c: Include syswait.h.

226 Use bool for boolean.
227 * gtkutil.c (xg_update_frame_menubar):
228 * xmenu.c (update_frame_menubar):
229 Return void, not int, since caller ignores return value.

252 2012-09-23 Eli Zaretskii <eliz@gnu.org>
254 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
255 fatal_error_backtrace.
257 * w32proc.c (sys_kill): Undo last change: don't do anything when
258 invoked to deliver SIGABRT to our own process. This is now
259 handled by emacs_raise.
261 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
263 * w32term.c (w32_read_socket): Remove leftover reference to
264 interrupt_input_pending.
266 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
268 Do not use SA_NODEFER.
269 Problem reported by Dani Moncayo in
270 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
272 * sysdep.c (emacs_abort): Do not reset signal handler.
273 * emacs.c (terminate_due_to_signal): Reset signal handler here.
274 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
275 wanted even on POSIXish hosts, and it doesn't work on Windows.
277 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
279 * xterm.c (x_term_init): Call fixup_locale before and after calling
280 gtk_init (Bug#12392).
282 2012-09-23 Chong Yidong <cyd@gnu.org>
284 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
285 Vdynamic_library_alist.
287 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
288 (Fgnutls_available_p): Caller changed.
290 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
291 (Flibxml_parse_xml_region): Likewise.
293 * dispextern.h (struct image_type): Remove arg from init function.
295 * image.c (Finit_image_library, lookup_image_type)
296 (define_image_type): Remove now-unneeded second arg.
297 (init_xpm_functions, init_png_functions, init_jpeg_functions)
298 (init_tiff_functions, init_gif_functions, init_svg_functions):
299 Arglist and w32_delayed_load calling convention changed.
300 (gs_type): Remove init_gs_functions; there is no such function.
301 (valid_image_p, make_image): Fix caller to lookup_image_type.
303 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
305 Simplify and avoid signal-handling races (Bug#12471).
307 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
308 Avoid recursive loop if there's a fatal error in the function itself.
309 * atimer.c (pending_atimers):
310 * blockinput.h: Don't include "atimer.h"; no longer needed.
311 (interrupt_input_pending): Remove. All uses removed.
312 pending_signals now counts both atimers and ordinary interrupts.
313 This is less racy than having three separate pending-signal flags.
314 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
316 Rename from their upper-case counterparts BLOCK_INPUT,
317 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
318 INPUT_BLOCKED_P, and turn into functions. All uses changed.
319 This makes it easier to access volatile variables more accurately.
320 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
321 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
322 that's more reliable if the code is buggy and sets
323 interrupt_input_blocked to a negative value. All uses changed.
324 * atimer.c (deliver_alarm_signal):
325 Remove. No need to deliver this to the parent; any thread can
326 handle this signal now. All uses replaced by underlying handler.
327 * atimer.c (turn_on_atimers):
328 * dispnew.c (handle_window_change_signal):
329 * emacs.c (handle_danger_signal):
330 * keyboard.c (kbd_buffer_get_event):
331 Don't reestablish signal handler; not needed with sigaction.
332 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
334 Rework to avoid unnecessary accesses to volatile variables.
335 (UNBLOCK_INPUT_TO): Now a function.
336 (totally_unblock_input, unblock_input): New decls.
337 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
338 (init_data): Remove. Necessary stuff now done in init_signal.
339 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
340 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
341 (fatal_error_code): Remove; no longer needed.
342 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
343 it doesn't always backtrace. All uses changed. No need to reset
344 signal to default, since sigaction and/or die does that for us now.
345 Use emacs_raise (FOO), not kill (getpid (), FOO).
346 (main): Check more-accurately whether we're dumping.
347 Move fatal-error setup to sysdep.c
348 * floatfns.c: Do not include "syssignal.h"; no longer needed.
349 * gtkutil.c (xg_get_file_name, xg_get_font):
350 Remove no-longer-needed signal-mask manipulation.
351 * keyboard.c, process.c (POLL_FOR_INPUT):
352 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
353 * keyboard.c (read_avail_input): Remove.
354 All uses replaced by gobble_input.
355 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
356 (kbd_buffer_store_event_hold, gobble_input):
357 (record_asynch_buffer_change) [USABLE_SIGIO]:
358 (store_user_signal_events):
359 No need to mess with signal mask.
360 (gobble_input): If blocking input and there are terminals, simply
361 set pending_signals to 1 and return. All hooks changed to not
362 worry about whether input is blocked.
363 (process_pending_signals): Clear pending_signals before processing
364 them, in case a signal comes in while we're processing.
365 By convention callers now test pending_signals before calling us.
366 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
367 New functions, to support changes to blockinput.h.
368 (handle_input_available_signal): Now extern.
369 (reinvoke_input_signal): Remove. All uses replaced by
371 (quit_count): Now volatile, since a signal handler uses it.
372 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
373 All callers changed. Block SIGINT only if not already blocked.
374 Clear sigmask reliably, even if Fsignal returns, which it can.
375 Omit unnecessary accesses to volatile var.
376 (quit_throw_to_read_char): No need to restore sigmask.
377 * keyboard.c (gobble_input, handle_user_signal):
378 * process.c (wait_reading_process_output):
379 Call signal-handling code rather than killing ourselves.
380 * lisp.h: Include <float.h>, for...
381 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
382 (pending_signals): Now volatile.
383 (syms_of_data): Now const if IEEE floating point.
384 (handle_input_available_signal) [USABLE_SIGIO]:
385 (terminate_due_to_signal, record_child_status_change): New decls.
386 * process.c (create_process): Avoid disaster if memory is exhausted
387 while we're processing a vfork, by tightening the critical section
389 (send_process_frame, process_sent_to, handle_pipe_signal)
390 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
392 (send_process): No need for setjmp/longjmp any more, since the
393 SIGPIPE stuff is now gone. Instead, report an error if errno
395 (record_child_status_change): Now extern. PID and W are now args.
396 Return void, not bool. All callers changed.
397 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
398 Remove. All uses removed. This bug should be fixed now in a
400 (wait_for_termination_1): Use waitpid rather than sigsuspend,
401 and record the child status change directly. This avoids the
402 need to futz with the signal mask.
403 (process_fatal_action): Move here from emacs.c.
404 (emacs_sigaction_flags): New function, containing
405 much of what used to be in emacs_sigaction_init.
406 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
407 caught by emacs, to make races less likely.
408 (deliver_process_signal): Rename from handle_on_main_thread.
410 (BACKTRACE_LIMIT_MAX): Now at top level.
411 (thread_backtrace_buffer, threadback_backtrace_pointers):
413 (deliver_thread_signal, deliver_fatal_thread_signal):
414 New functions, for more-accurate delivery of thread-specific signals.
415 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
416 (deliver_arith_signal): Handle in this thread, not
417 in the main thread, since it's triggered by this thread.
418 (maybe_fatal_sig): New function.
419 (init_signals): New arg DUMPING so that we can be more accurate
420 about whether we're dumping. Caller changed.
421 Treat thread-specific signals differently from process-general signals.
422 Block all signals while handling fatal error; that's safer.
423 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
425 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
426 Ignore SIGPIPE unless batch.
427 (emacs_backtrace): Output backtrace for the appropriate thread,
428 which is not necessarily the main thread.
429 * syssignal.h: Include <stdbool.h>.
430 (emacs_raise): New macro.
431 * xterm.c (x_connection_signal): Remove; no longer needed
432 now that we use sigaction.
433 (x_connection_closed): No need to mess with sigmask now.
434 (x_initialize): No need to reset SIGPIPE handler here, since
435 init_signals does this for us now.
437 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
439 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
440 background rect may be larger (Bug#12245).
442 2012-09-23 Chong Yidong <cyd@gnu.org>
444 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
446 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
448 * .gdbinit: Just stop at fatal_error_backtrace.
449 See Stefan Monnier's request in
450 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
451 Remove no-longer-used query of system type.

455 * search.c (Freplace_match): Doc fix (Bug#12325).
457 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
459 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
460 (Fline_end_position): Doc fix.
462 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
464 2012-09-22 Chong Yidong <cyd@gnu.org>
466 * dispextern.h (struct image_type): Add new slot, storing a type
467 initialization function.
469 * image.c (define_image_type): Call the image initializer function
470 if it is defined. Arguments and return value changed.
471 (valid_image_p, make_image): Callers changed.
472 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
473 (gif_type, imagemagick_type, svg_type, gs_type):
474 Add initialization functions.
475 (Finit_image_library): Call lookup_image_type.
476 (CHECK_LIB_AVAILABLE): Macro deleted.
477 (lookup_image_type): Call define_image_type here, rather than via
478 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
479 (syms_of_image): Move define_image_type calls for xbm_type and
480 pbm_type to lookup_image_type.
482 2012-09-22 Eli Zaretskii <eliz@gnu.org>
484 * keyboard.c (timer_check_2): Move calculation of 'timers' and
485 'idle_timers' from here ...
486 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
487 lists, to avoid infloops when the timer does something stupid,
488 like reinvoke itself with the same or smaller time-out.
491 2012-09-22 Martin Rudalics <rudalics@gmx.at>
493 * window.c (Fsplit_window_internal): Handle only Qt value of
494 Vwindow_combination_limit separately.
495 (Qtemp_buffer_resize): New symbol.
496 (Vwindow_combination_limit): New default value.
499 2012-09-22 Eli Zaretskii <eliz@gnu.org>
501 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
502 the new overlay string. (Bug#10159)
504 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
506 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
507 or that fprintf is async-signal-safe. POSIX doesn't require
510 2012-09-22 Chong Yidong <cyd@gnu.org>
512 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
515 2012-09-22 Kenichi Handa <handa@gnu.org>
517 * composite.c (composition_reseat_it): Handle the case that a
518 grapheme cluster is not covered by a single font (Bug#12352).
520 2012-09-21 Chong Yidong <cyd@gnu.org>
522 * image.c (define_image_type): Avoid adding duplicate types to
523 image_types (Bug#12463). Suggested by Jörg Walter.
525 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
527 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
528 (print_load_command_name): Add case LC_DATA_IN_CODE.
529 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
531 2012-09-21 Glenn Morris <rgm@gnu.org>
533 * eval.c (Frun_hook_with_args_until_success)
534 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
536 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
538 * fileio.c (Ffile_selinux_context): Only call freecon when
539 lgetfilecon succeeded.
540 (Fset_file_selinux_context): Likewise. (Bug#12444)
542 2012-09-21 Eli Zaretskii <eliz@gnu.org>
544 * xdisp.c (try_window_reusing_current_matrix): Under bidi
545 reordering, locate the cursor by calling set_cursor_from_row; if
546 that fails, clear the desired glyph matrix before returning a
547 failure indication to the caller. Fixes leaving garbled display
548 when fast scrolling with a down-key. (Bug#12403)
549 (compute_stop_pos_backwards): Fix a typo that caused crashes while
550 scrolling through multibyte text.
552 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
554 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
555 calling mark_vectorlike since that's the one that marks the window.
556 (mark_discard_killed_buffers): Mark the final cdr.
557 * window.h (struct window): Move prev/next_buffers to the
559 * window.c (make_window): Initialize prev/next_buffers manually.
561 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
563 Omit unused arg EXPECTED from socket hooks.
564 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
565 * nsterm.m (ns_term_init):
566 * termhooks.h (struct terminal.read_socket_hook):
567 * w32inevt.c (w32_console_read_socket):
568 * w32term.c (w32_read_socket):
569 * xterm.c (XTread_socket):
570 Omit unused arg EXPECTED. All callers changed.
571 (store_user_signal_events): Return void, not int, since callers no
572 longer care about the return value. All uses changed.
574 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
576 * w32gui.h (XParseGeometry): Do not declare.
578 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
580 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
581 Ignore 'expected'. See Eli Zaretskii in
582 <http://bugs.gnu.org/12471#8> (last line).
584 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
585 (XParseGeometry): Now static. Substitute extremal values for
586 values that are out of range.
588 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
590 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
592 * nsfns.m (XParseGeometry): Remove.
593 (Fx_create_frame): Call x_set_offset to correctly interpret
596 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
597 (Fx_parse_geometry): If there is a space in string, call
598 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
600 2012-09-17 Eli Zaretskii <eliz@gnu.org>
602 * search.c (scan_buffer): Use character positions in calls to
603 region_cache_forward and region_cache_backward, not byte
604 positions. (Bug#12196)
606 * w32term.c (w32_read_socket): Set pending_signals to 1, like
607 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
609 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
610 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
611 emacs_blocked_malloc, now deleted.
613 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
615 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
616 The workaround was for improving performance on Solaris 2.4, but
617 is getting in the way now. Emacs will still work if someone is
618 still running Solaris 2.4 in a museum somewhere; Sun dropped
619 support for Solaris 2.4 in 2003.
620 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
621 * process.c (create_process) [HAVE_WORKING_VFORK]:
622 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
623 since Emacs no longer uses vfork on that platform.
625 2012-09-17 Glenn Morris <rgm@gnu.org>
627 * emacs.c: Use COPYRIGHT.
629 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
631 Remove configure's --without-sync-input option (Bug#12450).
632 When auditing signal-handling in preparation for cleaning it up,
633 I found that SYNC_INPUT has race conditions and would be a real
634 pain to fix. Since it's an undocumented and deprecated
635 configure-time option, now seems like a good time to remove it.
636 Also see <http://bugs.gnu.org/11080#16>.
637 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
638 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
639 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
641 (check_depth) [XMALLOC_OVERRUN_CHECK]:
642 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
643 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
644 (dont_register_blocks, bytes_used_when_reconsidered)
645 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
646 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
647 [!SYSTEM_MALLOC && !SYNC_INPUT]:
648 Remove. All uses removed.
649 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
650 implementation, one that depends on whether the new macro
651 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
653 * atimer.c (run_timers, handle_alarm_signal):
654 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
655 (handle_async_input, process_pending_signals)
656 (handle_input_available_signal, init_keyboard):
657 * nsterm.m (ns_read_socket):
658 * process.c (wait_reading_process_output):
659 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
660 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
662 * xterm.c (XTread_socket):
664 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
665 * eval.c (handling_signal): Remove. All uses removed.
666 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
667 All uses replaced with the SYNC_INPUT version.
668 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
670 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
673 * font.c (Ffont_shape_gstring): Remove unused local.
675 2012-09-16 Glenn Morris <rgm@gnu.org>
677 * Makefile.in (clean): No longer run nextstep's clean.
679 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
681 (ns-app): Move here from ns.mk, and simplify.
682 (clean): Simplify nextstep entry.
683 * ns.mk: Remove file.
685 2012-09-17 Kenichi Handa <handa@gnu.org>
687 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
688 not covert the last few charactes.
690 2012-09-16 Kenichi Handa <handa@gnu.org>
692 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
693 here, but just check the validity of glyphs in the glyph-string.
695 2012-09-16 Martin Rudalics <rudalics@gmx.at>
697 * window.c (Fwindow_parameter, Fset_window_parameter):
698 Accept any window as argument (Bug#12452).
700 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
702 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
703 to ns_term_init to avoid memory leak.
705 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
706 explicit retain/release.
707 (ns_term_init): Only allow one display. Initialize outerpool and
710 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
712 Port _setjmp fix to POSIXish hosts as well as Microsoft.
713 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
714 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
715 the Microsoft problem in a different way, by altering ../nt/config.nt.
717 2012-09-15 Eli Zaretskii <eliz@gnu.org>
732 * w16select.c: Remove inclusion of setjmp.h, as it is now included
733 by lisp.h. This completes removal of setjmp.h inclusion
734 erroneously announced in the previous commit. (Bug#12446)
736 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
739 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
740 not defined as a macro. The latter happens on MS-Windows.
743 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
745 Port better to POSIX hosts lacking _setjmp (Bug#12446).
746 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
747 Some instances of '#include <setjmp.h>' removed, if the
748 only reason for the instance was because "lisp.h" was included.
749 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
750 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
751 and _longjmp with the new symbols. Emacs already uses _setjmp if
752 available, so this change affects only POSIXish hosts that have
753 sigsetjmp but not _setjmp, such as some versions of Solaris and
754 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
755 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
756 (png_load_body) [HAVE_PNG]:
757 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
758 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
759 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
760 since PNG requires jmp_buf. This is the only exception to the
761 general rule that we now use sys_setjmp and sys_longjmp.
762 This exception is OK since this code does not change the signal
763 mask or longjmp out of a signal handler.
765 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
767 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
768 Include "syssignal.h", for 'main_thread'.
770 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
772 Avoid out-of-range marker position (Bug#12426).
773 * insdel.c (replace_range, replace_range_2):
774 Adjust markers before overlays, as suggested by comments.
775 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
776 Remove redundant check before calling offset_intervals.
778 2012-09-14 Martin Rudalics <rudalics@gmx.at>
780 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
781 current buffer (Bug#12387).
783 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
785 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
787 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
789 Use a more backwards-compatible timer format (Bug#12430).
790 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
791 vector element, not from the 4th, since PSECS is now at the end.
792 (Fcurrent_idle_time): Doc fix.
794 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
796 Function to mark objects and remove killed buffers at once.
797 * alloc.c (discard_killed_buffers): Rename to ...
798 (mark_discard_killed buffers) ... new name. Add marking
799 of remaining objects. Fix comment. Adjust users.
800 (mark_object): Do not touch frame buffer lists here.
801 * frame.c (delete_frame): Reset frame buffer lists here.
803 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
805 Better workaround for GNOME bug when --enable-gcc-warnings.
806 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
807 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
808 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
810 Simplify SIGIO usage (Bug#12408).
811 The code that dealt with SIGIO was crufty and confusing, e.g., it
812 played tricks like "#undef SIGIO" but these tricks were not used
813 consistently. Simplify mostly by not #undeffing standard symbols,
814 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
815 or not as we please) rather than "defined SIGIO" (standard symbol
816 that we probably shouldn't #undef).
817 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
818 Modules that need it can include it.
819 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
820 * dispextern.h (ignore_sigio): New decl.
821 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
822 unconditionally, since it's now a no-op if !USABLE_SIGIO.
823 * emacs.c (shut_down_emacs):
824 * keyboard.c (kbd_buffer_store_event_hold):
825 Use ignore_sigio rather than invoking 'signal' directly.
826 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
828 (FIONREAD, SIGIO): Do not #undef.
829 (tty_read_avail_input): Use #error rather than a syntax error.
830 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
831 for I_PIPE, used by SETUP_SLAVE_PTY.
832 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
833 * sysdep.c (croak): Remove; no longer needed. This bit of
834 temporary code, with Fred N. Fish's comment that it's temporary,
835 has been in Emacs since at least 1992!
836 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
837 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
838 * syssignal.h (croak): Remove decl.
839 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
840 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
841 now that we're termios-only.
842 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
843 * term.c (dissociate_if_controlling_tty): Use #error rather than
846 Work around GCC and GNOME bugs when --enable-gcc-warnings.
847 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
848 to work around GNOME bug 683906.
849 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
850 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
851 This works around GCC bug 54561.
853 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
855 More fixes for 'volatile' and setjmp/longjmp.
856 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
857 * image.c (struct png_load_context) [HAVE_PNG]: New type.
858 (png_load_body) [HAVE_PNG]:
859 (jpeg_load_body) [HAVE_JPEG]:
860 New function, with most of the old parent function's body.
861 (png_load) [HAVE_PNG]:
862 (jpeg_load) [HAVE_JPEG]:
863 Invoke the new function, to avoid longjmp munging our locals.
864 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
865 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
866 longjmp is passed 2, as the C standard doesn't guarantee this.
867 Instead, store the failure code into mgr->failure_code.
869 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
871 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
872 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
873 (syms_of_keyboard): Remove support for unread-command-char.
875 2012-09-12 Eli Zaretskii <eliz@gnu.org>
877 * w32proc.c (sys_kill): If PID is our process ID and the signal is
878 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
879 violation. (Bug#12426)
881 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
883 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
885 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
887 * eval.c: Add `inhibit-debugger'.
888 (Qinhibit_debugger): New symbol.
889 (call_debugger): Bind it instead of Qdebug_on_error.
890 (maybe_call_debugger): Test Vinhibit_debugger.
891 (syms_of_eval): Define inhibit-debugger.
892 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
893 (syms_of_xdisp): Remove inhibit-debug-on-message.
895 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
897 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
898 If a nonvolatile local variable is written before a _longjmp to
899 the frame containing the variable, and is read after the _longjmp,
900 the value read is indeterminate. Some local variables of type
901 'struct handler' and 'struct catchtag' are used in this way, so
902 mark each of their slots as volatile if the slot can be set before
903 _longjmp and read afterwards.
904 * lisp.h (struct handler): var and chosen_clause are now volatile.
905 (struct catchtag): val, next, and pdlcount are now volatile.
907 * bidi.c (bidi_push_it, bidi_pop_it):
908 * fns.c (copy_hash_table):
909 * image.c (define_image_type):
910 * keyboard.c (kbd_buffer_store_event_hold):
911 * process.c (Fprocess_send_eof):
912 * xfaces.c (x_create_gc) [HAVE_NS]:
913 * xgselect.c (xg_select):
914 Prefer assignment to memcpy when either will do.
916 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
917 Use pointer-to-a-pointer to simplify and avoid a NILP check each
918 time an item is removed. No need to mark this function 'inline';
919 the compiler knows better than we do.
921 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
923 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
924 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
925 to change_frame_size (Bug#12388).
926 (windowDidResize:): Pass YES to updateFrameSize.
928 * nsterm.h: Add delay parameter to updateFrameSize.
930 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
932 Discard killed buffers from deleted window and frame objects.
933 This reduces an amount of references to killed buffers and
934 helps GC to reclaim them faster.
935 * alloc.c (discard_killed_buffers): New function.
936 (mark_object): Use it for deleted windows and frames.
937 (mark_object): If symbol's value is set up for a killed buffer
938 or deleted frame, restore it's global binding.
939 * data.c (swap_in_global_binding): Add GC notice.
940 (swap_in_symval_forwarding): Use convenient set_blv_where.
941 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
942 * window.h: ... to here.
944 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
946 Convenient macro to check whether the buffer is live.
947 * buffer.h (BUFFER_LIVE_P): New macro.
948 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
949 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
951 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
953 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
954 composition cases (Bug#12364).
956 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
957 overhang of succeeding glyphs overlapping box cursor.
959 * w32term.c (x_draw_glyph_string): Likewise.
961 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
963 Simplify, document, and port floating-point (Bug#12381).
964 The porting part of this patch fixes bugs on non-IEEE platforms
965 with frexp, ldexp, logb.
966 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
968 * floatfns.c: Simplify discussion of functions that Emacs doesn't
969 support, by removing commented-out code and briefly listing the
970 C89 functions excluded. The commented-out stuff was confusing
971 maintenance, e.g., we thought we needed cbrt but it was commented out.
972 (logb): Remove decl; no longer needed.
973 (isfinite): New macro, if not already supplied.
974 (isnan): Don't replace any existing macro.
975 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
976 are present on all C89 platforms.
977 (Ffrexp): Do not special-case zero, as frexp does the right thing
979 (Flogb): Do not use logb, as it doesn't have the desired meaning
980 on hosts that use non-base-2 floating point. Instead, stick with
981 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
982 frexp, to avoid getting an unspecified result.
984 * xdisp.c (Qinhibit_debug_on_message): Now static.
986 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
988 * nsterm.m (ns_update_begin): Set clip path to whole view by using
989 NSBezierPath (Bug#12131).
991 2012-09-10 Chong Yidong <cyd@gnu.org>
993 * fns.c (Fdelq, Fdelete): Doc fix.
995 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
997 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
998 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
1000 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
1002 * lisp.h (make_lisp_ptr): New macro to replace XSET.
1003 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
1006 2012-09-09 Eli Zaretskii <eliz@gnu.org>
1008 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
1009 left fringe if the window has a left margin. This avoids leaving
1010 traces of the cursor because its leftmost pixel is not drawn over.
1012 * dispnew.c (update_window_line): When the left margin area of a
1013 screen line is updated, set the redraw_fringe_bitmaps_p flag of
1014 that screen line. (Bug#12277)
1016 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
1018 Assume C89 or later for math functions (Bug#12381).
1019 This simplifies the code, and makes it a bit smaller and faster,
1020 and (most important) makes it easier to clean up signal handling
1021 since we can stop worring about floating-point exceptions in
1022 library code. That was a problem before C89, but the problem
1023 went away many years ago on all practical Emacs targets.
1024 * data.c, image.c, lread.c, print.c:
1025 Don't include <math.h>; no longer needed.
1026 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
1027 might be autoconfigured, as that never happens.
1029 * doprnt.c (DBL_MAX_10_EXP):
1030 * print.c (DBL_DIG):
1031 Remove. C89 or later always defines these.
1032 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
1033 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
1034 (arith_error, domain_error, domain_error2):
1035 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
1036 no longer needed -- we simply return what C returns. All uses removed.
1037 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
1039 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
1040 Remove. All uses expanded, as these macros are no longer used
1041 more than once and are now more trouble than they're worth.
1042 (Ftan): Use tan, not sin / cos.
1043 (Flogb): Assume C89 frexp.
1044 (fmod_float): Assume C89 fmod.
1045 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
1046 (init_floatfns): Remove. All uses removed.
1048 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1050 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
1051 compositeToPoint for OSX < 10.6 (Bug#12390).
1053 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
1055 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
1056 This produces more-accurate results.
1058 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1060 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
1061 changes (Bug#12088).
1063 2012-09-08 Chong Yidong <cyd@gnu.org>
1065 * syntax.c (Fstring_to_syntax): Doc fix.
1067 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1069 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
1070 in the internal border.
1071 (x_set_window_size): Remove static variables and their usage.
1072 (ns_redraw_scroll_bars): Fix NSTRACE arg.
1073 (ns_after_update_window_line, ns_draw_fringe_bitmap):
1074 Remove fringe/internal border adjustment (Bug#11052).
1075 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
1076 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
1077 (ns_fix_rect_ibw): Remove.
1078 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
1079 (ns_dumpglyphs_box_or_relief): Ditto.
1080 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
1082 (ns_dumpglyphs_image): Ditto.
1083 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
1085 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
1086 their usage. Add fringe_extended_p and its use as in other terms.
1087 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
1088 scroll bar was removed.
1089 (updateFrameSize): New function.
1090 (windowDidResize): Move code to updateFrameSize and call it.
1092 * nsterm.h (EmacsView): Add updateFrameSize.
1094 2012-09-07 Chong Yidong <cyd@gnu.org>
1096 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
1098 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
1100 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1102 More signal-handler cleanup (Bug#12327).
1103 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
1104 Problem introduced when merging patches. Noted by Eli Zaretskii in
1105 <http://bugs.gnu.org/12327#67>.
1106 * floatfns.c: Comment fix.
1107 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
1108 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
1109 and anyway the declaration is harmless even if SIGDANGER is not defined.
1110 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
1111 defined BROKEN_FIONREAD). systty.h formerly did this, but other
1112 source files not surprisingly expected syssignal.h to define, or
1113 not define, SIGIO, and it's cleaner to do it that way, for consistency.
1114 Include <sys/ioctl.h>, for FIONREAD.
1115 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
1116 This eliminates a problem whereby other files mysteriously had
1117 to include "syssignal.h" before including "systty.h" if they
1118 wanted to use "#ifdef SIGIO".
1120 2012-09-07 Eli Zaretskii <eliz@gnu.org>
1122 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
1124 * w32.c (sigemptyset): Empty the set.
1125 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
1127 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
1129 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
1131 * alloc.c (mark_buffer): Revert unsafe marking optimization.
1132 (mark_object): Likewise for frame objects.
1134 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1136 * syssignal.h (handle_on_main_thread): Always declare,
1137 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
1138 This ports to platforms without HAVE_PTHREAD.
1140 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1142 Signal-handler cleanup (Bug#12327).
1143 Emacs's signal handlers were written in the old 4.2BSD style with
1144 sigblock and sigmask and so forth, and this led to some
1145 inefficiencies and confusion. Rewrite these to use
1146 pthread_sigmask etc. without copying signal sets around. Also,
1147 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
1148 'signal', and instead use functions that do not attempt to take
1149 over the system name space. This patch causes Emacs's text
1150 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
1151 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
1152 Do not include <signal.h> or "syssignal.h", as these
1153 modules do not use signals.
1154 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
1155 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
1156 Do not include <signal.h>, as "syssignal.h" does that for us now.
1157 * atimer.c (sigmask_atimers): New function.
1158 (block_atimers, unblock_atimers): New functions,
1159 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
1161 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
1162 no longer needed here.
1163 * emacs.c (main): Inspect existing signal handler with sigaction,
1164 so that there's no need to block and unblock SIGHUP.
1165 * sysdep.c (struct save_signal): New member 'action', replacing
1166 old member 'handler'.
1167 (save_signal_handlers, restore_signal_handlers):
1168 Use sigaction instead of 'signal' to save and restore.
1169 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
1170 New function. All users of 'signal' modified to use set_sighandler
1171 if they're writeonly, and to use sys_signal if they're read+write.
1172 (emacs_sigaction_init, forwarded_signal): New functions.
1173 (sys_signal): Remove. All uses replaced by calls to sigaction
1174 and emacs_sigaction_init, or by direct calls to 'signal'.
1175 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
1176 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
1177 all uses replaced by pthread_sigmask etc. calls.
1178 * syssignal.h: Include <signal.h>.
1179 (emacs_sigaction_init, forwarded_signal): New decls.
1180 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
1181 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
1182 (sigmask, sys_sigmask): Remove; no longer needed.
1183 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
1184 (sigblock, sigunblock, sigfree):
1185 (sigsetmask) [!defined sigsetmask]:
1186 Remove. All uses replaced by pthread_sigmask.
1187 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
1188 no longer need to be replaced, and its typical old uses
1189 are now done via emacs_sigaction_init and sigaction.
1190 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
1191 (sys_sigdel): Remove; unused.
1192 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
1194 2012-09-06 Eli Zaretskii <eliz@gnu.org>
1196 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
1197 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
1199 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1201 Explicitly mark buffer_defaults and buffer_local_symbols.
1202 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
1203 mark_local_symbols here.
1204 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
1205 since special buffers aren't marked here any more.
1206 (allocate_buffer): Chain new buffer with all_buffers here...
1207 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
1209 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
1210 (syms_of_buffer): Remove staticpro of the above.
1211 (init_buffer_once): Set names for buffer_defaults and
1212 buffer_local_symbols.
1214 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1216 Use bool for booleans in font-related modules.
1217 * font.c (font_intern_prop, font_style_to_value)
1218 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
1219 (generate_otf_features, font_check_otf_features, font_check_otf)
1220 (font_match_p, font_list_entities, font_at):
1221 * fontset.c (fontset_id_valid_p, reorder_font_vector
1222 (fontset_find_font, Fset_fontset_font)
1223 (face_suitable_for_char_p) [0]:
1224 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
1225 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
1226 (m17n_flt_initialized, ftfont_shape_by_flt):
1227 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
1228 * nsfont.m (nsfont_draw):
1229 * w32font.c (w32font_draw):
1230 * w32term.c (x_draw_glyphless_glyph_string_foreground):
1231 Use bool for booleans.
1232 * font.h: Adjust to above API changes.
1233 (struct font, struct font_driver, struct font_driver_list):
1234 Use bool for booleans.
1235 (struct font): Remove useless member encoding_type.
1237 * fontset.c, xftfont.c: Omit unnecessary static decls.
1239 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1241 * alloc.c (mark_object): Revert window marking code
1242 since it's unsafe for the Fset_window_configuration.
1244 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1246 Fix race conditions with signal handlers and errno (Bug#12327).
1247 Be more systematic about preserving errno whenever a signal
1248 handler returns, even if it's not in the main thread. Do this by
1249 renaming signal handlers to distinguish between signal delivery
1250 and signal handling. All uses changed.
1251 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
1252 * data.c (deliver_arith_signal): Rename from arith_error.
1253 * dispnew.c (deliver_window_change_signal): Rename from
1254 window_change_signal.
1255 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
1256 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
1257 * keyboard.c (deliver_input_available_signal): Rename from
1258 input_available_signal.
1259 (deliver_user_signal): Rename from handle_user_signal.
1260 (deliver_interrupt_signal): Rename from interrupt_signal.
1261 * process.c (deliver_pipe_signal): Rename from send_process_trap.
1262 (deliver_child_signal): Rename from sigchld_handler.
1263 * atimer.c (handle_alarm_signal):
1264 * data.c (handle_arith_signal):
1265 * dispnew.c (handle_window_change_signal):
1266 * emacs.c (handle_fatal_signal, handle_danger_signal):
1267 * keyboard.c (handle_input_available_signal):
1268 * keyboard.c (handle_user_signal, handle_interrupt_signal):
1269 * process.c (handle_pipe_signal, handle_child_signal):
1270 New functions, with the actual signal-handling code taken from the
1271 original respective signal handlers, sans the sporadic attempts to
1272 preserve errno, since that's now done by handle_on_main_thread.
1273 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
1274 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
1275 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1277 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1278 Move initialization of main_thread to sysdep.c's init_signals.
1279 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
1280 our usage, and simplifies the mainline code.
1281 (record_child_status_change): New static function, as a helper
1282 for handle_child_signal, and with most of the old child handler's
1284 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
1285 (handle_child_signal): Use the above.
1286 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1287 Moved here from emacs.c.
1288 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
1289 code moved here from emacs.c's main function.
1290 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
1291 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
1292 This lets callers save and restore errno properly.
1294 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1296 Remove redundant or unused things here and there.
1297 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
1298 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
1299 * editfns.c (Fcompare_buffer_substrings): Likewise.
1300 * frame.h (struct terminal, struct font_driver_list):
1301 Remove redundant declarations.
1302 * window.h (Qleft, Qright): Likewise.
1304 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1306 Do not mark objects from deleted buffers, windows and frames.
1307 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
1308 (mark_object): Likewise for windows and frames.
1310 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1312 * alloc.c (valid_lisp_object_p): Treat killed buffers,
1313 buffer_defaults and buffer_local_symbols as valid objects.
1314 Return special value to denote them.
1316 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1318 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
1319 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
1320 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
1321 (file_name_absolute_p, Fsubstitute_in_file_name):
1322 (check_executable, check_writable, Ffile_accessible_directory_p)

1324 (Finsert_file_contents, choose_write_coding_system)
1325 (Fwrite_region, build_annotations, a_write, e_write)
1327 * filelock.c (boot_time_initialized, get_boot_time)
1328 (get_boot_time_1, lock_file_1, within_one_second):
1329 * floatfns.c (in_float):
1330 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
1331 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
1332 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
1333 * lisp.h (struct Lisp_Hash_Table.cmpfn):
1334 * window.c (compare_window_configurations):
1335 Use bool for booleans.
1336 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
1337 (Fdefault_file_modes): Now mode_t, not int, for modes.
1338 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
1339 (internal_delete_file): Now returns void, not a (boolean) int,
1340 since nobody was looking at the return value.
1341 * lisp.h, window.h: Adjust to above API changes.
1343 * xdisp.c (set_message): Simplify and reindent last change.
1345 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
1347 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
1349 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
1351 * eval.c (call_debugger): Make the function non-static so that we
1352 can call it from set_message.
1354 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
1355 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
1357 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1359 Give more-useful info on a fatal error (Bug#12328).
1360 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
1361 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
1362 of doing the work ourselves.
1363 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
1364 do most of the work.
1365 (fatal_error_backtrace): New function, taken from the guts
1366 of the old fatal_error_signal, but with a new option to output
1368 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
1369 info about the signal than just its number.
1370 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
1371 * sysdep.c: Include <execinfo.h>
1372 (emacs_backtrace): New function, taken partly from the previous
1373 code of the 'die' function.
1374 (emacs_abort): Call fatal_error_backtrace rather than abort.
1376 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
1378 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
1379 eager (load-time) macro-expansion.
1380 * lisp.mk (lisp): Add macroexp.
1382 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1384 Simplify redefinition of 'abort' (Bug#12316).
1385 Do not try to redefine the 'abort' function. Instead, redo
1386 the code so that it calls 'emacs_abort' rather than 'abort'.
1387 This removes the need for the NO_ABORT configure-time macro
1388 and makes it easier to change the abort code to do a backtrace.
1389 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
1390 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
1391 Remove; sysdep.c's emacs_abort now takes its place.
1392 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
1393 'abort' changed to use 'emacs_abort'.
1394 * msdos.c (dos_abort) [defined abort]: Remove; not used.
1395 (abort) [!defined abort]: Rename to ...
1396 (emacs_abort): ... new name.
1397 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
1398 the place of the old 'abort' in emacs.c.
1399 * w32.c, w32fns.c (abort): Do not #undef.
1400 * w32.c (emacs_abort): Rename from w32_abort.
1402 2012-09-04 Eli Zaretskii <eliz@gnu.org>
1404 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
1405 offsets[j].dv, since the y axis of the screen coordinates points
1406 down, while the y axis of the font definition coordinates points
1407 up. This fixes display of Arabic diacritics such as KASRA and
1408 KASRATAN. (Bug#11860)
1410 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1412 Be more systematic about _setjmp vs setjmp.
1413 * alloc.c (test_setjmp, mark_stack):
1414 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
1415 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
1416 (png_load, my_error_exit, jpeg_load):
1417 * process.c (send_process_trap, send_process):
1418 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
1419 The underscored versions are up to 30x faster on some hosts.
1420 Formerly, the code used setjmp+longjmp sometimes and
1421 _setjmp+_longjmp at other times, with no particular reason to
1422 prefer setjmp+longjmp.
1424 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
1426 Fix minor problem found by static checking.
1427 * buffer.c (Fdelete_all_overlays): Return nil.
1429 2012-09-03 Martin Rudalics <rudalics@gmx.at>
1431 * buffer.c (Fdelete_all_overlays): New function.
1433 2012-09-03 Chong Yidong <cyd@gnu.org>

1453 EXCLUDE_SUBRS_P. All callers changed.
1454 * dispextern.h, lisp.h: Reflect above API changes.
1455 * firstfile.c (dummy): Use the address of 'main', whose signature
1456 won't change, instead of the address of 'initialize', whose
1457 signature just changed from int to bool.
1458 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
1459 * msdos.c (fatal_error_in_progress): ... from here.
1460 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
1462 (redisplay_internal, unwind_redisplay): Simply clear
1463 REDISPLAYING_P when unwinding, instead of saving its previous,
1464 always-false value and then restoring it.
1466 Clean up some extern decls.
1467 Mostly, this hoists extern decls out of .c files and into .h files.
1468 That way, we're more likely to catch errors if the interfaces change.
1469 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
1470 declare xg_mark_data.
1471 * dispextern.h (x_frame_parm_handlers):
1473 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

1489 * xfont.c (x_clear_errors):
1490 * xterm.c (x_frame_parm_handlers):
1491 Remove now-redundant extern decls.
1492 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
1493 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
1495 * xfaces.c: Remove unnecessary static decls.
1496 * xterm.c (updating_frame): Remove decl of nonexistent object.
1498 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
1499 when building globals.h, as the objects that are not built on
1500 this host are not needed to compile C files on this host.
1502 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
1504 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

1552 2012-09-01 Eli Zaretskii <eliz@gnu.org>
1554 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
1555 more than one grapheme cluster passed to the shaper: compute the
1556 offset adjustment values separately for each cluster. (Bug#11860)
1558 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1559 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1560 about implicit conversions from integer to pointer.
1562 2012-09-01 Daniel Colascione <dancol@dancol.org>
1564 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
1565 system used too early.
1567 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
1569 Better seed support for (random).

1618 window system declarations.
1620 * frame.h: Move common functions here: set_frame_menubar,
1621 x_set_window_size, x_sync, x_get_focus_frame,
1622 x_set_mouse_position, x_set_mouse_pixel_position,
1623 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

1647 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
1649 Remove mark_ttys function and fix tty_display_info initialization.
1650 * lisp.h (mark_ttys): Remove prototype.
1651 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
1652 to mark_ttys because all possible values of 'top_frame' slot are
1653 the frames which are reachable from Vframe_list.
1654 * term.c (mark_ttys): Remove.
1655 (init_tty): Safely initialize 'top_frame' slot with Qnil.

1684 * lread.c (init_lread): For out-of-tree builds, only add the
1685 source directory's site-lisp dir to the load-path if it exists,
1686 consistent with in-tree builds. (Bug#12302)
1688 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

1707 Handle click on close button as quit.
1709 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
1710 Add window_closed and button_values. Add void as return value for
1711 add(Button|String|Split). addButton takes int instead of Lisp_Object.
1712 Add process_dialog as new member.
1714 2012-08-28 Eli Zaretskii <eliz@gnu.org>
1716 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

1820 * dired.c (file_name_completion):
1821 * process.h (fd_callback):
1822 Omit int (actually boolean) argument. It wasn't being used.
1824 * composite.h, lisp.h: Reflect above API changes.
1826 * cmds.c, coding.c: Use bool for booleans.
1827 * cmds.c (move_point, Fself_insert_command):
1828 * coding.h (struct composition status, struct coding_system):
1829 * coding.c (detect_coding_utf_8, encode_coding_utf_8)
1830 (detect_coding_utf_16, encode_coding_utf_16, detect_coding_emacs_mule)
1831 (emacs_mule_char, decode_coding_emacs_mule)
1832 (encode_coding_emacs_mule, detect_coding_iso_2022)
1833 (decode_coding_iso_2022, encode_invocation_designation)
1834 (encode_designation_at_bol, encode_coding_iso_2022)

1845 (Funencodable_char_position, code_convert_region)
1846 (code_convert_string, code_convert_string_norecord)
1847 (Fset_coding_system_priority):
1848 * fileio.c (Finsert_file_contents):
1849 Use bool for booleans.
1850 * coding.h, lisp.h: Reflect above API changes.
1851 * coding.c: Remove unnecessary static function decls.
1852 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
1853 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
1854 not a boolean 'int', since callers never look at the return value.
1855 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
1856 * coding.h (decoding_buffer_size, encoding_buffer_size)
1857 (emacs_mule_string_char): Remove unused extern decls.
1858 (struct iso_2022_spec, struct coding_system):
1859 Use 'unsigned int : 1' for boolean fields, since there's more than one.
1860 (struct emacs_mule_spec): Remove unused field 'full_support'.
1861 All initializations removed.
1862 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
1864 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
1866 Fix spare memory change (Bug#12286).
1867 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
1868 (valid_lisp_object_p): Likewise.
1870 2012-08-27 Martin Rudalics <rudalics@gmx.at>
1872 * window.c (Fset_window_configuration): Record any window's old
1873 buffer if it's replaced (see Bug#8789). If the new current
1874 buffer doesn't appear in the selected window, go to its old
1877 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
1879 Special MEM_TYPE_SPARE to denote reserved memory.
1880 * alloc.c (enum mem_type): New memory type.
1881 (refill_memory_reserve): Use new type for spare memory.
1882 This prevents live_cons_p and live_string_p from incorrect
1883 detection of uninitialized objects from spare memory as live.
1885 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
1888 * Makefile.in (.PHONY): versioclean -> versionclean.
1890 Remove unused external symbols.
1891 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
1892 * window.c (Qwindow_valid_p, decode_valid_window):
1893 Now static, not extern.
1894 * data.c (Qinterval): Remove; unused.
1895 (syms_of_data): Do not define 'interval'.
1896 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
1897 * window.h (decode_valid_window):
1900 * character.c, charset.c, chartab.c: Use bool for booleans.
1901 * character.c (lisp_string_width, string_count_byte8)
1902 (string_escape_byte8):
1903 * charset.c (charset_map_loaded, load_charset_map, read_hex):
1904 (load_charset_map_from_file, map_charset_chars)
1905 (Fdefine_charset_internal, define_charset_internal)
1906 (Fdeclare_equiv_charset, find_charsets_in_text)
1907 (Ffind_charset_region, char_charset, Fiso_charset):
1908 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
1909 (sub_char_table_set, sub_char_table_set_range)
1910 (char_table_set_range, optimize_sub_char_table)
1911 (map_sub_char_table):
1912 Use bool for boolean.
1913 * character.c (str_to_unibyte): Omit last boolean argument; it was
1914 always 0. All callers changed.
1915 * character.h, charset.h: Adjust to match previous changes.
1916 * character.h (char_printable_p): Remove decl of nonexistent function.
1917 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
1918 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
1919 are all boolean, so make them single-bit bitfields.
1921 * lisp.h (ASET): Remove attempt to detect side effects.
1922 It was meant to be temporary and it often doesn't work,
1923 because when IDX has side effects the behavior of IDX==IDX
1924 is undefined. See Stefan Monnier in
1925 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
1927 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
1929 * lisp.h (functionp): New function (extracted from Ffunctionp).
1930 (FUNCTIONP): Use it.
1931 * eval.c (Ffunctionp): Use it.
1933 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1935 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
1936 as that's faster and simpler than static storage. Don't bother
1937 with the g_main_context_query overhead if g_main_context_pending
1938 says no events are pending.
1939 (gfds, gfds_size): Remove these static vars.
1940 (xgselect_initialize): Remove; no longer needed.
1941 All uses and decls removed.
1943 * emacs.c (fatal_error_signal_hook): Remove.
1944 All uses removed. This leftover from old code was always 0.
1946 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
1947 * casefiddle.c (casify_object, casify_region):
1948 * casetab.c (set_case_table):
1949 * category.c, category.h (word_boundary_p):
1950 * category.h (CHAR_HAS_CATEGORY):
1951 Use bool for booleans, instead of int.
1953 2012-08-25 Eli Zaretskii <eliz@gnu.org>
1955 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
1957 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1959 On assertion failure, print backtrace if available.
1960 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1961 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1962 * Makefile.in (LIB_EXECINFO): New macro.
1965 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1966 * bytecode.c (exec_byte_code):
1967 * callint.c (check_mark, Fcall_interactively):
1968 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1969 (getenv_internal, sync_process_alive, call_process_exited):
1970 * lisp.h (USE_SAFE_ALLOCA):
1971 Use bool for booleans, instead of int.
1972 * lisp.h, process.h: Adjust prototypes to match above changes.
1973 * callint.c (Fcall_interactively): Don't assume the mark's
1974 offset fits in 'int'.
1976 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1978 * buffer.c, buffer.h: Use bool for boolean.
1979 * buffer.c (reset_buffer_local_variables)
1980 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1981 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
1982 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
1983 (overlay_touches_p, overlay_strings, Foverlay_put)
1984 (report_overlay_modification, call_overlay_mod_hooks):
1985 (mmap_enlarge, mmap_set_vars):
1986 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1987 Use bool for booleans, instead of int.
1988 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1989 since the 1-or-0 return value is always ignored anyway.
1990 (mmap_initialized_p):
1991 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1992 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1994 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1996 * bidi.c: Use bool for boolean.
1997 This is a bit more readable, and makes the text segment of bidi.o
1998 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1999 Presumably it's faster too.
2000 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
2002 (bidi_cache_find_level_change, bidi_cache_iterator_state)
2003 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
2004 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
2005 (bidi_explicit_dir_char, bidi_level_of_next_char)
2006 (bidi_find_other_level_edge, bidi_move_to_visually_next):
2007 Use bool for booleans, instead of int.
2008 * dispextern.h (bidi_init_it, bidi_paragraph_init)
2009 (bidi_unshelve_cache): Adjust decls to match code.
2011 2012-08-23 Martin Rudalics <rudalics@gmx.at>
2013 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
2016 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2018 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
2019 * atimer.h: Include <stdbool.h>.
2021 2012-08-22 Dan Nicolaescu <dann@gnu.org>
2023 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
2024 compile time tests instead of run time tests on systems that do
2026 (FRAME_MAC_P): Remove leftover from deleted code.
2027 * frame.c (syms_of_frame): Remove leftover from deleted code.
2029 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
2031 * nsterm.m (insertText:): Don't clear modifiers if code is space.
2033 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
2035 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
2036 Otherwise, the compiler complains about (A?B:C) where B is void
2037 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
2038 (fontset_add): Return void, for FONTSET_ADD.
2040 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2042 * alloc.c: Use bool for booleans.
2043 (gc_in_progress, abort_on_gc)
2044 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2045 (dont_register_blocks) [GC_MALLOC_CHECK]:
2046 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
2047 (check_string_bytes, make_specified_string, memory_full)
2048 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
2049 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
2050 (mark_stack, valid_pointer_p, make_pure_string)
2051 (Fgarbage_collect, survives_gc_p, gc_sweep):
2052 Use bool for booleans, instead of int.
2053 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2054 Remove unused local.
2055 * alloc.c (PURE_POINTER_P):
2056 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
2057 * editfns.c (Fformat):
2058 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
2060 * fns.c (sweep_weak_table):
2061 * lisp.h (suppress_checking, push_message, survives_gc_p)
2062 (make_pure_string, gc_in_progress, abort_on_gc):
2063 * lread.c (readchar, read1):
2064 * print.c (Fprin1_to_string):
2065 * xdisp.c (push_message):
2066 Use bool for booleans affected directly or indirectly by
2069 Make recently-introduced setters macros.
2070 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
2071 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
2072 (set_fontset_default, set_fontset_fallback): Rename from their
2073 upper-case counterparts, and make them functions rather than macros.
2074 This is more consistent with the other recently-introduced setters.
2075 These don't need to be inline, since they're local.
2077 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
2079 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
2080 the loop (Bug#12247).
2082 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2084 * lisp.h (vcopy): Use memcpy rather than our own loop.
2085 This fixes a performance regression introduced by the recent
2086 addition of vcopy. This means 'vcopy' will need to be modified
2087 for a copying collector, but that's OK. Also, tighten the
2088 checking in the assertion.
2090 2012-08-21 Eli Zaretskii <eliz@gnu.org>
2092 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
2093 components for RTL text (Bug#11860). Adjust X-OFFSET of each
2094 non-base glyph for the width of the base character, according to
2095 what x_draw_composite_glyph_string_foreground expects.
2096 Generate WADJUST value according to composition_gstring_width's
2097 expectations, to produce correct width of the composed character.
2098 Reverse the sign of the DU offset produced by ScriptPlace.
2100 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2102 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
2104 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2106 Avoid direct writes to contents member of struct Lisp_Vector.
2107 * lisp.h (vcopy): New function to copy data into vector.
2108 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
2109 * fns.c (Ffillarray): Use ASET.
2110 * keyboard.c (timer_check_2): Use AREF and ASET.
2111 (append_tool_bar_item, Frecent_keys): Use vcopy.
2112 * lread.c (read_vector): Use ASET.
2113 * msdos.c (Frecent_doskeys): Use vcopy.
2114 * xface.c (Finternal_copy_lisp_face): Use vcopy.
2115 (Finternal_merge_in_global_face): Use ASET and vcopy.
2116 * xfont.c (xfont_list_pattern): Likewise.
2118 2012-08-21 Martin Rudalics <rudalics@gmx.at>
2120 * window.c (Fwindow_point): For the selected window always return
2121 the position of its buffer's point.
2122 (Fset_window_point): For the selected window always go in its
2123 buffer to the specified position.
2125 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2127 Setter macros for fontsets.
2128 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
2129 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
2130 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
2133 2012-08-20 Glenn Morris <rgm@gnu.org>
2135 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
2136 Don't assume that `ln -f' works.
2138 2012-08-20 Eli Zaretskii <eliz@gnu.org>
2140 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
2141 and later about non-assignments with no effect. See discussion at
2142 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
2145 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2147 Inline setter functions for Lisp_Objects slots of struct specbinding.
2148 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
2151 2012-08-20 Martin Rudalics <rudalics@gmx.at>
2153 * window.c (select_window): Always make selected window's buffer
2156 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2158 Use AREF and ASET for docstrings of category tables.
2159 * category.h (CATEGORY_DOCSTRING): Use AREF.
2160 (SET_CATEGORY_DOCSTRING): Use ASET.
2161 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
2163 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2165 Inline setter functions for hash table members.
2166 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
2167 (set_hash_hash, set_hash_index): Rename with _slot suffix.
2168 (set_hash_key_and_value, set_hash_index, set_hash_next)
2169 (set_hash_hash): New functions.
2170 * charset.c, fns.c: Adjust users.
2172 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2174 Inline getter and setter functions for per-buffer values.
2175 * buffer.h (per_buffer_default, set_per_buffer_default)
2176 (per_buffer_value, set_per_buffer_value): New functions.
2177 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
2178 * buffer.c, data.c: Adjust users.
2180 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
2182 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
2184 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
2186 Rely on <config.h> + <unistd.h> to declare 'environ',
2187 as gnulib does this if the system doesn't.
2188 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
2189 Remove declaration. MS-Windows declares it on stdlib.h which is
2190 included by conf_post.h.
2191 * emacs.c (environ) [DOUG_LEA_MALLOC]:
2192 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
2193 * vm-limit.c: Include <unistd.h>, for 'environ'.
2195 * unexaix.c, unexcoff.c: Include "mem-limits.h".
2196 (start_of_data): Remove decl; mem-limits.h provides it.
2198 * xdisp.c (handle_invisible_prop): Make it a bit faster
2199 and avoid a gcc -Wmaybe-uninitialized diagnostic.
2201 2012-08-19 Chong Yidong <cyd@gnu.org>
2203 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
2206 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
2208 * .gdbinit: Use call instead of set when calling a function in the
2211 * data.c (set_internal): Don't use set_blv_found.
2212 (Fkill_local_variable): Likewise.
2214 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
2216 * nsfont.m (ns_ascii_average_width): Ensure the string
2217 ascii_printable is initialized with a null-terminated character
2218 array. Otherwise, it can contain undesired extra characters.
2220 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2222 port new setting code to Sun C 5.8 2005/10/13
2223 * chartab.c, lisp.h (char_table_set, char_table_set_range):
2224 Return void, not Lisp_Object. Otherwise, the compiler
2225 complains about (A?B:C) where B is void and C is Lisp_Object
2226 when compiling CHAR_TABLE_SET, due to the recent change to
2227 the API of sub_char_table_set_contents.
2229 2012-08-18 Chong Yidong <cyd@gnu.org>
2231 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
2232 for the string case (Bug#3874).
2234 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2236 * buffer.h (BSET): Remove (Bug#12215).
2237 Replace all uses with calls to new setter functions.

3173 since it's used in non-static inline functions now.
3175 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

3225 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
3227 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
3228 This how ASET and AREF are supposed to work, and makes
3229 it easier to think about future improvements. See
3230 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.

3613 (w32_kbd_patch_key, key_event): Use the codepage returned by
3614 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
3615 (key_event): use uChar.UnicodeChar only if

3646 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
3647 enumeration constants, as PURE and HEAP are too general, and clash
3648 with other headers and sources, such as gmalloc.c and the
3649 MS-Windows system headers. All users changed.
3651 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3653 Revert last save_excursion_save and save_excursion_restore changes.
3654 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

3667 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
3668 arms of an 'if', not using conditional expressions; otherwise GDB
3669 complains about the types in the unevaluated arm when the argument
3670 is an integer literal.
3671 (xgetint): Simplify expression.
3672 * alloc.c (gdb_make_enums_visible): New constant. This ports to
3673 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
3674 Zaretskii in <http://bugs.gnu.org/12036#13>.
3675 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
3676 needed now that we have gdb_make_enums_visible.
3677 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
3678 (enum enum_USE_LSB_TAG):
3679 New enum types, packaging up enums that need to be exported to GDB.

3703 * lisp.h (struct Lisp_Excursion): New data type.
3704 (PVEC_EXCURSION): New pseudovector type.
3705 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
3706 to deal with it. Adjust comments.

3721 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
3722 emacs.c, as this is a more-suitable home. Had this been done earlier
3723 the fix for 12036 would have avoided some of the problems noted in
3724 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
3725 would have been more obvious.
3726 * emacs.c: Do not include <verify.h>; no longer needed.
3727 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
3728 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
3729 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

3733 (DATA_SEG_BITS): Use it.
3734 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
3735 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3736 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3737 not be usable in #if. This simplifies things.
3739 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
3741 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

3746 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3747 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3748 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3749 Adjust to changes in lisp.h and emacs.c, by using
3750 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
3751 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
3752 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
3753 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
3754 instead of gdb_valbits.
3755 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
3756 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
3757 instead of gdb_array_mark_flag.
3758 (xboolvector): Get size from $->size, not $->header.size.
3759 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
3760 (xreload, hook-run, hookpost-run): Remove.
3761 * emacs.c: Include <verify.h>.
3762 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
3763 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
3765 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
3766 (gdb_USE_LSB_TAG): New enum constants.
3767 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3768 Also define these as enum constants, so they're visible to GDB.
3769 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
3770 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
3771 as constants, so they're visible to GDB.
3772 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)

3774 Now enum constants, not macros, so they're visible to GDB.
3775 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
3776 more convenient now. All uses changed.
3777 (VALMASK) [USE_LSB_TAG]: Also define in this case.
3778 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
3780 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

3787 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
3788 add argument, tune behavior, and adjust all callers.
3790 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
3792 Use typedef for EMACS_INT, EMACS_UINT.
3793 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
3794 than macros. This simplifies debugging in the usual case, since
3795 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
3796 and it allows expressions involving EMACS_INT casts.
3797 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
3799 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

3809 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
3811 Adjust buffer text indirection counters at the end of Fkill_buffer.
3812 * buffer.c (Fkill_buffer): Adjust indirection counters when the
3813 buffer is definitely dead. This should really fix an issue reported
3814 by Christoph Scholtes again. (Bug#12007).
3815 (init_buffer_once): Initialize indirection counters of
3816 buffer_defaults and buffer_local_symbols (for sanity and safety).
3818 2012-07-24 Eli Zaretskii <eliz@gnu.org>
3820 * xdisp.c (init_iterator): Don't compute dimensions of truncation
3821 and continuation glyphs on tooltip frames, leave them at zero.

3824 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
3826 Simplify copy_overlay.
3827 * buffer.c (copy_overlay): Simplify. Use build_marker.

3847 (build_overlay): Add prototype.
3849 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3851 Swap buffer text indirection counters in Fbuffer_swap_text.
3852 * buffer.c (Fbuffer_swap_text): Swap indirections too.
3853 This avoids crash reported by Christoph Scholtes at
3854 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
3856 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
3858 * nsmenu.m (Popdown_data): New struct.
3859 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
3861 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
3862 (initWithContentRect): Make imgView and contentView non-static
3863 and autorelease them. Also autorelease img and matrix (Bug#12005).
3864 (dealloc): Remove (Bug#12005).
3866 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
3868 Adjust consing_since_gc when objects are explicitly freed.

3881 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
3883 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
3884 as it's limited by the amount of memory, not by INT_MAX.
3886 2012-07-21 Eli Zaretskii <eliz@gnu.org>
3888 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
3889 in special-event-map. See the discussion at

3948 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
3949 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
3950 Adjust users accordingly.

3970 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
3971 'for_each_per_buffer_object_at'.
3972 All uses changed. It's better to use upper-case for macros that
3973 cannot be implemented as functions, to give the reader a clue
3974 that they're special.

4612 * s/aix4-2.h (unix): Remove; no longer needed.
4614 EMACS_TIME simplification (Bug#11875).
4615 This replaces macros (which typically do not work in GDB)
4616 with functions, typedefs and enums, making the code easier to debug.
4617 The functional style also makes code easier to read and maintain.
4618 * systime.h: Include <sys/time.h> on all hosts, not just if
4619 WINDOWSNT, since 'struct timeval' is needed in general.

4632 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4633 not functions. All uses rewritten to use the following, respectively:
4634 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
4635 (add_emacs_time, sub_emacs_time): New functions.
4636 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

4638 * xterm.c (XTflash): Get the current time closer to when it's used.
4639 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

4656 Prefer memcmp to strncmp when either will do.
4657 * nsterm.m: Include <ftoastr.h>.
4659 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
4660 Prefer snprintf to strncpy.
4661 * nsterm.m (ns_term_init):
4662 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4663 * nsterm.m (ns_term_init):
4664 Avoid the need for strncpy, by using build_string or
4665 make_unibyte_string directly. Use dtoastr, not snprintf.
4666 * process.c (Fmake_network_process): Diagnose service names that
4667 are too long, rather than silently truncating them or creating
4668 non-null-terminated names.
4669 (Fnetwork_interface_info): Likewise, for interface names.
4670 * sysdep.c (system_process_attributes) [GNU_LINUX]:
4671 Prefer sprintf to strncat.

4684 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
4685 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
4686 where argument type is known to be a Lisp_Cons.

4698 Optimize pure C strings initialization.
4699 * lisp.h (make_pure_string): Fix prototype.
4700 (build_pure_c_string): New function, defined as static inline. This
4701 provides a better opportunity to optimize away calls to strlen when
4702 the function is called with compile-time constant argument.
4703 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
4704 argument, adjust users accordingly. Use build_pure_c_string where

4707 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
4708 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

4737 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
4738 We include usg5-4-common.h, which defines them both.
4740 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
4741 O_RDONLY already includes it).
4743 Stop ns builds setting the EMACSLOADPATH environment variable.
4744 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4745 Now it does not set EMACSLOADPATH, just returns the load-path string.
4746 * nsterm.h: Update accordingly.
4747 * lread.c [HAVE_NS]: Include nsterm.h.
4748 (init_lread) [HAVE_NS]: Use ns_load_path.

4751 2012-07-09 Glenn Morris <rgm@gnu.org>
4753 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
4754 since the included bsd-common.h does so.
4756 Stop ns builds setting the EMACSPATH environment variable.
4757 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
4758 (ns_init_paths): Do not set EMACSPATH.
4759 * nsterm.h (ns_exec_path): Add it.
4760 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
4763 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
4765 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
4767 * process.c (wait_reading_process_output): 'waitchannels' was unset
4768 when read_kbd || !NILP (wait_for_cell); fix this.
4770 Add GCC-style 'const' attribute to functions that can use it.
4771 * character.h (char_resolve_modifier_mask):
4772 * keyboard.h (make_ctrl_char):
4773 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

4784 Minor improvements to make_formatted_string.
4785 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
4786 where int is good enough, as vsprintf returns an int.
4787 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
4789 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>

4818 Move marker debugging code under MARKER_DEBUG.
4819 * marker.c (MARKER_DEBUG): Move marker debugging code under
4820 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4821 for bootstrap with --enable-checking (~3x slowdown reported
4822 by Juanma Barranquero <lekktu@gmail.com>).
4823 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4825 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4827 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.

4832 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4833 has no font, use the frame's font. (Bug#11813)
4834 (display_line): Add commentary about displaying truncation glyphs
4836 (produce_special_glyphs): Move here from term.c.
4838 * term.c (produce_special_glyphs): Move to xdisp.c.
4840 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4843 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4845 * xdisp.c (display_line): Avoid warning about implicit declaration
4848 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4850 * lisp.h: Remove empty conditional.
4852 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4854 * lread.c (load_path_check): Now static.
4856 Fix some minor --with-ns problems found by static checking.

4860 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4861 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4862 Remove unused local.

4875 * lread.c (load_path_check): New function, split from init_lread.
4876 (init_lread): Reorganize. Motivation:
4877 If EMACSLOADPATH is set, check/warn about that rather than the
4878 defaults, which we are not going to use. Hence we can remove
4879 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4880 Don't warn if site-lisp directories are missing.
4881 If not installed, start from a blank load-path, since
4882 PATH_LOADSEARCH refers to the eventual installation directories.
4884 2012-07-07 Eli Zaretskii <eliz@gnu.org>

4893 GUI frame without a fringe to display continuation or truncation
4895 (insert_left_trunc_glyphs): Support GUI frames: make sure
4896 truncation glyphs overwrite enough glyphs from the current line to
4897 have sufficient space in pixels.
4898 (display_line): Support truncation and continuation glyphs on GUI
4899 frames. If some spare pixels are left on the line after inserting
4900 the truncation glyphs, fill that space with a stretch glyph of a
4901 suitably computed width.
4903 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4904 produce_glyphs, to support GUI sessions.
4906 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4908 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4910 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4912 Do not require float-time's arg to fit in time_t (Bug#11825).
4913 This works better on hosts where time_t is unsigned, and where
4914 float-time is applied to the (negative) difference between two times.
4915 * editfns.c (decode_time_components): Last arg is now double *,
4916 not int *, and means to store all the result as a double, without
4917 worrying about whether the seconds part fits in time_t.
4918 All callers changed.
4919 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4920 All callers changed.
4921 (Ffloat_time): Do not fail merely because the specified time falls
4922 outside of time_t range.
4924 2012-07-07 Glenn Morris <rgm@gnu.org>
4926 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

4937 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4939 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

4941 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
4942 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.

4946 * xfont.c (compare_font_names): Redo to omit the need for casts.
4948 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4950 * xfns.c (Fx_change_window_property): Doc fix.
4951 * w32fns.c (Fx_change_window_property): Doc fix.
4953 * w32fns.c (Fx_window_property): Accept the same arguments as the
4954 X Windows version. Doc fix.
4955 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4957 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4958 Eli Zaretskii <eliz@gnu.org>
4960 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4961 Windows-specific code from nt/config.nt moved here.
4962 Obsolete settings removed.
4964 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4966 * process.c: Avoid unnecessary calls to gettime.
4967 (wait_reading_process_output): Don't get the time of day
4968 when gobbling data immediately and not waiting, as there's no need
4969 for it in that case. This removes a FIXME.
4971 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4973 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4974 is defined (Bug#11768).

4978 Fix marker debugging code.
4979 * marker.c (byte_char_debug_check): Do not perform the check
4980 if buffer is not multibyte.
4981 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4982 Call byte_char_debug_check with correct arguments.
4984 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4986 Compile marker debugging code only if ENABLE_CHECKING is defined.
4987 * marker.c (byte_char_debug_check, count_markers):
4988 Use only if ENABLE_CHECKING is defined.
4989 (byte_debug_flag): Remove.
4990 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4991 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4993 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4995 Avoid code repetition in marker-related functions.
4996 * marker.c (attach_marker): New function.
4997 (Fset_marker, set_marker_restricted, set_marker_both)
4998 (set_marker_restricted_both): Use it.
4999 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
5000 Consistently rename charno to charpos.
5001 (marker_position): Add eassert.
5002 (marker_byte_position): Convert to eassert.

5014 * lisp.h (build_marker): New prototype.
5015 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
5016 * composite.c (autocmp_chars): Likewise.
5017 * editfns.c (buildmark): Remove.
5018 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
5019 (save_restriction_save): Use build_marker.
5020 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
5021 * window.c (save_window_save): Likewise.
5023 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5025 Do not use Fdelete_overlay in delete_all_overlays
5026 to avoid redundant calls to unchain_overlay.
5027 * buffer.c (drop_overlay): New function.
5028 (delete_all_overlays, Fdelete_overlay): Use it.
5029 * minibuf.c (get_minibuffer): Fix comment.
5031 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5033 Port to OpenBSD 5.1 amd64.
5034 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
5035 This is needed for OpenBSD, and should be harmless on all BSD systems.
5036 Also, include <sys/sysctl.h>, as it should be available on all
5037 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
5038 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
5039 use p_pid member, not kp_proc.pid.
5041 2012-07-06 Glenn Morris <rgm@gnu.org>
5043 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
5045 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5047 More xmalloc and related cleanup.

5055 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
5056 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
5058 Omit needless casts involving void * pointers and allocation.
5059 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
5060 as the former is more robust if P's type is changed.
5061 Prefer xzalloc to xmalloc + memset 0.
5062 Simplify malloc-or-realloc to realloc.
5063 Don't worry about xmalloc returning a null pointer.
5064 Prefer xstrdup to xmalloc + strcpy.
5065 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
5067 * keyboard.c (apply_modifiers_uncached): Prefer local array to
5068 alloca of a constant.
5070 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5072 * xdisp.c (display_line): Fix horizontal pixel coordinates when
5073 hscroll is larger than the line width. Fixes long and futile
5074 looping inside extend_face_to_end_of_line (on a TTY) producing
5075 glyphs that are not needed and thrown away.
5077 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5079 * marker.c (set_marker_restricted_both): Simplify by using
5082 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

5093 followed by gtk_box_set_homogeneous (Bug#11768).
5094 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
5095 (update_theme_scrollbar_width, xg_create_scroll_bar):
5096 Use gtk_scrollbar_new (Bug#11768).
5097 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
5098 (is_box_type): New function (Bug#11768).
5099 (xg_tool_item_stale_p): Call is_box_type.
5100 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
5101 with default display (Bug#11768).

5105 * xdisp.c (window_hscroll_limited): New function.
5106 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
5107 coordinates when window's hscroll is set to insanely large
5110 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
5112 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

5173 * fileio.c (time_error_value): Check the right error number.
5174 Problem reported by Troels Nielsen in
5175 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

5179 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
5180 This should be fixed in a better way; see Eli Zaretskii in
5181 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
5182 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
5184 * fileio.c (time_error_value): Rename from special_mtime.
5185 The old name's problems were noted by Eli Zaretskii in
5186 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
5188 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
5189 This variable's comment says Emacs needs at least one GDB-visible
5190 symbol of type enum pvec_type, to work around GDB problems.
5191 The symbol's value doesn't matter.
5193 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
5194 that causes compilation to fail on pre-C99 compilers.
5196 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
5198 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

5211 (PSEUDOVECTOR_SIZE_BITS): New constant.
5212 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
5213 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
5214 change in pvec_type.

5221 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
5222 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
5223 (sweep_vectors): Use it. Use local var `total_bytes' instead of
5224 abusing vector->header.next.nbytes.
5225 (live_vector_p): Use PVEC_TYPE.
5226 (mark_object): Adapt code to extract pvectype. Use switch.
5228 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5230 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
5231 Tighten new eassert a bit.
5233 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5235 Fix compilation with --enable-gcc-warnings and -O1
5237 * doprnt.c (doprnt): Change type of tem to int, initialize
5238 to avoid compiler warning. Add eassert.
5239 * search.c (simple_search): Initialize match_byte to avoid
5240 compiler warning. Add eassert.
5242 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5244 Avoid weird behavior with large horizontal scrolls.
5245 Without this change, for example, large hscroll values would
5246 mess up Emacs's display on Fedora 15 x86, presumably due to
5247 overflows in int calculations in the display code.
5248 Also, if buffers had long lines, Emacs would freeze.
5249 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
5250 (set_window_hscroll): New function, containing the old guts of
5251 Fset_window_hscroll. Return the clipped value.
5252 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
5253 This avoids the need to check against PTRDIFF_MAX.
5255 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
5257 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

5261 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5263 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
5264 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
5265 since GCC 4.4.6 issues a bogus warning for them.
5267 Fix bugs in file timestamp newness comparisons.
5268 * fileio.c (Ffile_newer_than_file_p):
5269 * lread.c (Fload): Use full timestamp resolution of files,
5270 not just the 1-second resolution, so that files that are only
5271 slightly newer still count as newer.
5272 * fileio.c (Ffile_newer_than_file_p): Don't assume file
5273 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
5275 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
5277 * fileio.c: Improve handling of file time marker. (Bug#11852)
5278 (special_mtime): New function.

5280 Use it to set special mtime values consistently.
5282 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
5284 * fileio.c (Finsert_file_contents): Properly handle st_mtime
5285 marker for non-existing file. (Bug#11852)
5287 2012-07-03 Glenn Morris <rgm@gnu.org>
5289 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
5290 and did not make it into globals.h).
5292 2012-07-03 Tom Tromey <tromey@redhat.com>

5330 2012-07-03 Glenn Morris <rgm@gnu.org>
5332 * lisp.h (Frandom): Make it visible to C.
5333 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
5334 buffer for invisible buffers. (Bug#1229)

5338 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
5339 values which aren't power of 2.
5340 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
5341 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
5344 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
5346 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

5352 * alloc.c (allocate_vector_block): Remove redundant
5353 calls to mallopt if DOUG_LEA_MALLOC is defined.
5354 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
5355 avoid calls to mallopt if zero_vector is returned.
5357 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5359 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
5360 is enabled, avoid dereferencing NULL current_sblock if
5363 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5365 Cleanup basic buffer management.
5366 * buffer.h (struct buffer): Change layout to use generic vector
5367 marking code. Fix some comments. Change type of 'clip_changed'
5368 to bitfield. Remove unused #ifndef old.
5369 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.

5373 (Fbuffer_local_variables): Use it.
5374 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
5375 * alloc.c (allocate_buffer): Adjust to match new layout of
5376 struct buffer. Fix comment.
5377 (mark_overlay): New function.
5378 (mark_buffer): Use it. Use mark_vectorlike to mark normal
5379 Lisp area of struct buffer.
5380 (mark_object): Use it. Adjust marking of misc objects
5381 and related comments.
5383 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
5385 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
5386 wrapper that is not needed because the wrapped code is a no-op (zero
5387 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
5388 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
5390 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
5392 * alloc.c (mark_buffer): Simplify. Remove prototype.
5393 (mark_object): Add comment. Reorganize marking of vector-like
5394 objects. Use CHECK_LIVE for all vector-like objects except buffers
5395 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
5396 Avoid redundant calls to mark_vectorlike for bool vectors.
5398 2012-06-30 Glenn Morris <rgm@gnu.org>
5400 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
5402 * epaths.in (PATH_SITELOADSEARCH): New.
5403 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
5404 This is rather than relying on --enable-locallisppath elements
5405 having "site-lisp" in their names. (Bug#10208#25, 11658)
5407 2012-06-30 Eli Zaretskii <eliz@gnu.org>
5409 * w32proc.c (sys_select): Accept and ignore one more argument.
5411 * w32.c (emacs_gnutls_pull): Call select with one more argument.
5413 * sysselect.h [DOS_NT]: Don't include sys/select.h.
5414 (pselect) [!MS_DOS]: Redirect to sys_select.
5416 * sysdep.c: Don't include dos.h and dosfns.h.
5418 * process.c (sys_select):
5419 * msdos.c (sys_select): Accept one more argument and ignore it.
5421 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
5422 adapt data types and code to that.
5425 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
5426 which clashes with the gnulib function of the same name.
5428 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
5430 * font.c (font_style_to_value, font_style_symbolic)
5431 (font_prop_validate_style): Add type checks for values in
5434 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
5436 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
5439 2012-06-29 Eli Zaretskii <eliz@gnu.org>
5441 * xdisp.c (try_window_id): Undo last change.
5443 * w32.c (getwd): Adjust commentary about startup_dir.
5444 (init_environment): Always call sys_access, even in non-MSVC
5445 builds. Don't chdir to the directory of the Emacs executable.
5446 This undoes code from 1997 which was justified by the need to
5447 "avoid conflicts when removing and renaming directories". But its
5448 downside was that every relative file name was being interpreted
5449 relative to the directory of the Emacs executable, which can never
5450 be TRT. In particular, it broke sys_access when called with
5451 relative file names.
5452 (sys_access): Map GetLastError to errno.
5454 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5456 * window.h (struct window): Change type of 'fringes_outside_margins'
5457 to bitfield. Fix comment. Adjust users accordingly.

5460 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
5463 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

5466 Add QUIT to make the loop interruptible.
5468 2012-06-29 Glenn Morris <rgm@gnu.org>
5470 * charset.c (init_charset): Make lack of etc/charsets fatal.
5472 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5474 * editfns.c (region_limit): Fix type mismatch.
5476 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5478 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
5479 undefined. Convert from xassert to eassert.
5480 * nsmenu.m: Convert from xassert to eassert.
5481 * nsterm.m: Likewise.
5483 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
5485 * editfns.c (region_limit): Clip to narrowing (bug#11770).
5487 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
5489 Avoid integer overflow on scroll-left and scroll-right.
5490 * window.c (HSCROLL_MAX): New macro.
5491 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
5492 overflow when requested scroll falls outside ptrdiff_t range.

5496 * window.h (struct window): Change type of 'hscroll',
5497 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
5498 'last_modified' and 'last_overlay_modified' to EMACS_INT.
5499 Adjust users accordingly.
5500 * xdisp.c (try_cursor_movement): Replace type check with eassert.
5501 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
5502 from EMACS_INT to ptrdiff_t.
5503 (make_window): Omit redundant initialization.
5505 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
5507 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
5509 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
5511 * window.h (struct window): Change type of 'use_time' and
5512 'sequence_number' from Lisp_Object to int.

5522 Fix GLYPH_DEBUG usage assuming that it may be undefined,
5523 adjust comments accordingly.

5578 * alloc.c (allocate_string): Omit intervals initialization.
5579 * alloc.c (make_uninit_multibyte_string): Initialize intervals
5580 as in make_pure_string and make_pure_c_string.
5582 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
5584 * alloc.c (allocate_string): Fix last change.
5586 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

5634 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
5636 * alloc.c: Remove build_string.
5637 * lisp.h: Define build_string as static inline. This provides
5638 a better opportunity to optimize away calls to strlen when the
5639 function is called with compile-time constant argument.
5640 * image.c (imagemagick_error): Convert to build_string.
5641 * w32proc.c (sys_spawnve): Likewise.
5642 * xterm.c (x_term_init): Likewise.
5644 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
5646 Use sprintf return value instead of invoking strlen on result.
5647 In the old days this wasn't portable, since some sprintf
5648 implementations returned char *. But they died out years ago and
5649 Emacs already assumes sprintf returns int.
5650 Similarly for float_to_string.
5651 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
5652 * ccl.c (ccl_driver):
5653 * character.c (string_escape_byte8):

5656 * print.c (print_object):
5657 * xdisp.c (message_dolog):
5658 * xfns.c (syms_of_xfns):
5659 Use sprintf or float_to_string result to avoid need to call strlen.
5660 * data.c (Fnumber_to_string):
5661 Use make_unibyte_string, since the string must be ASCII.
5662 * lisp.h, print.c (float_to_string): Now returns int length.
5663 * term.c (produce_glyphless_glyph):
5664 Use sprintf result rather than recomputing it.
5666 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
5667 * Makefile.in (ALL_CFLAGS):
5668 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
5669 * gmalloc.c, regex.c: Include <config.h> unconditionally.

5673 * dispextern.h (xstrcasecmp): Define to library function
5674 strcasecmp if available.
5675 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.

5690 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
5692 * gtkutil.c (get_utf8_string): Remove redundant assignment.
5693 sprintf already null-terminates its output.
5695 * xfns.c (x_window): Remove redundant cast.
5697 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
5699 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
5700 `const char *' to `char *' to avoid compiler warning.
5702 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
5704 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
5705 instead of truncating it to 63 (admittedly a generous limit).
5707 * process.c: Fix spelling and caps in comments.
5709 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
5711 * emacs.c (setpgrp): Remove definition, unused.

5757 * sound.c (sound_warning, parse_sound):
5758 Remove unnecessary forward decls.
5760 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
5762 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

5764 * dispnew.c (Fsleep_for, sit_for):
5765 * keyboard.c (kbd_buffer_get_event):
5766 * process.c (Faccept_process_output):
5767 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
5768 This improves on the previous patch, which introduced a bug
5769 when time_t is unsigned and as wide as intmax_t.
5770 See <http://bugs.gnu.org/9000#51>.
5772 2012-06-23 Eli Zaretskii <eliz@gnu.org>

5779 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
5781 * makefile.w32-in: Update dependencies.
5783 * w32.c (ltime): Add return type and declare static.
5784 (w32_get_internal_run_time): Remove usused variable `time_100ns'.
5786 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
5788 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
5789 Privately reported by Herbert J. Skuhra.
5790 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
5792 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
5793 not make_lisp_timeval, when the argument is of type EMACS_TIME.
5795 2012-06-23 Eli Zaretskii <eliz@gnu.org>
5797 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
5798 last argument of make_unibyte_string.
5800 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
5801 language ID in the event parameters.
5803 * w32term.c (w32_read_socket): Put the new keyboard codepage into
5804 event.code, not the obscure "character set ID".
5806 2012-06-23 Chong Yidong <cyd@gnu.org>

5812 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

5817 * s/ms-w32.h (pselect): Redirect to sys_select.

5827 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
5828 Privately reported by Herbert J. Skuhra.

5835 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5837 Support higher-resolution time stamps (Bug#9000).
5838 The time stamps are only nanosecond-resolution at the C level,
5839 since that's the best that any real-world system supports now.
5840 But they are picosecond-resolution at the Lisp level, as that's
5841 easy, and leaves room for future OS improvements.
5843 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5846 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5847 Don't get current time unless it's needed.
5849 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5850 now provides it if it's absent.
5851 (start_atimer): Port to higher-res time stamps.
5852 Check for time stamp overflow. Don't get current time more
5853 often than is needed.
5855 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5856 Include systime.h, not time.h.
5857 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
5859 * dired.c: Include stat-time.h.
5860 (Ffile-attributes): File times now have higher resolution.
5862 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
5863 (struct image): Timestamp now has higher resolution.
5865 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5866 has at least microseconds now. All uses removed.
5867 (update_frame, update_single_window, update_window, update_frame_1)
5868 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5869 (duration_to_sec_usec): Remove; no longer needed.
5871 * editfns.c (time_overflow): Now extern.

5883 * fileio.c: Include <stat-time.h>
5884 (Fcopy_file): Copy higher-resolution time stamps.
5885 Prefer to set the time stamp via a file descriptor if that works.

5902 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5903 Port to higher-resolution time stamps. Do not assume time_t is signed.
5904 (decode_timer): New function. Timers are now vectors of length 9,
5905 not 8, to accommodate the picosecond component.
5906 (timer_check_2): Use it.
5908 * nsterm.m (select_timeout, timeval_subtract): Remove.
5909 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5910 as they're a bit more accurate and handle overflow better.

5912 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5913 * nsterm.h (ns_select): Adjust prototype.
5915 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5916 us-resolution time stamps.
5917 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5919 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5921 * lisp.h (time_overflow): New decl.

5935 (Fprocess_attributes): Now generates ns-resolution time stamps.
5937 * sysdep.c: Include utimens.h. Don't include utime.h
5938 or worry about struct utimbuf; gnulib does that for us now.

5945 Now returns ns-resolution time stamp. All uses changed.
5946 Check for time stamp overflow.
5948 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5949 provides a substitute now.
5951 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5952 since it guarantees struct timespec.
5953 (EMACS_TIME): Now struct timespec, so that we can support
5954 ns-resolution time stamps.
5955 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5956 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5957 (EMACS_USECS): Remove.
5958 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5959 so multiply the arg by 1000 before storing it.
5960 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
5962 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

5969 (make_timeval, make_lisp_time, decode_time_components): New decls.
5970 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
5971 that it mishandled time_t overflow. You can't compare by subtracting!
5972 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
5973 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

5984 (w32_get_internal_run_time):
5985 Port to higher-resolution Emacs time stamps.

6000 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
6001 (timeval_subtract): Remove; no longer needed.
6002 (XTflash, XTring_bell, x_wait_for_event):
6003 Port to ns-resolution time stamps. Don't assume time_t is signed.

6009 2012-06-22 Eli Zaretskii <eliz@gnu.org>
6011 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
6012 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
6013 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
6014 staticidx goes up to 1597 out of 1600 = 0x640.)
6016 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
6018 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

6064 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
6065 gets killed during executing of this function (Bug#11665).
6066 Try to always return Qt when the buffer has been actually killed.
6067 (Vkill_buffer_query_functions): In doc-string say that functions
6068 run by this hook should not change the current buffer.
6070 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
6072 Fix recently-introduced process.c problems found by static checking.
6073 * process.c (write_queue_push, write_queue_pop, send_process):

6090 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
6092 * lisp.h (eassert): Assume C89 or later.
6093 This removes the need for CHECK.
6094 (CHECK): Remove. Its comments about always evaluating its
6095 argument were confusing, as 'eassert' typically does not evaluate
6098 * coding.c (produce_chars): Use ptrdiff_t, not int.
6100 * xterm.c (x_draw_underwave): Check for integer overflow.
6101 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

6287 as the union type is for debugging, not for production.
6288 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
6289 Use an inline function on all platforms when using the union type,
6290 since this is simpler and 'static inline' can be used portably

6432 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
6434 * doprnt.c (doprnt): Truncate multibyte char correctly.
6435 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
6436 would mishandle a string argument "Xc" if X was a multibyte
6437 character of length 2: it would truncate after X's first byte
6438 rather than including all of X.
6440 2012-06-06 Chong Yidong <cyd@gnu.org>
6442 * buffer.c (word_wrap): Doc fix.

6491 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
6492 Convert pctcpu and pctmem to Lisp float properly.
6493 Let the compiler fold better, as 100.0/0x8000 is exact.
6495 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
6497 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
6500 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
6502 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
6504 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
6506 For a 'struct window', replace some Lisp_Object fields to
6507 bitfields where appropriate, remove unused fields.
6508 * window.h (struct window): Remove unused 'last_mark_x' and
6509 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
6510 change it's type from Lisp_Object to bitfield.
6511 Change type of 'force_start', 'optional_new_start',
6512 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
6513 fields from Lisp_Object to bitfield. Adjust users accordingly.
6515 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6517 Pacify gcc -Wdouble-precision when using Xaw.

6519 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
6520 Use 'float' consistently, rather than 'float' in most places
6521 and 'double' in a couple of places.
6523 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6525 * xdisp.c (handle_stop): Detect whether we have overlay strings
6526 loaded by testing it->current.overlay_string_index to be
6527 non-negative, instead of checking whether n_overlay_strings is
6528 positive. (Bug#11587)
6530 2012-05-31 Chong Yidong <cyd@gnu.org>
6532 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
6534 * doc.c (Fsubstitute_command_keys): Doc fix.
6536 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6538 * search.c (search_buffer): Remove calls to
6539 r_alloc_inhibit_buffer_relocation, as it is now called by
6540 maybe_unify_char, which was the cause of relocation of buffer text
6543 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6545 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6546 for the duration of call to load_charset, to avoid problems with
6547 callers of maybe_unify_char that access buffer text through C
6550 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6551 decrement the inhibition flag, instead of just setting or
6554 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6556 Remove obsolete '#define static' cruft.
6557 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6558 This #undef was "temporary" in 2000; it is no longer needed
6559 now that '#define static' has gone away.
6560 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6561 (gray_bitmap_bits): Remove; no longer needed.
6562 All uses replaced with definiens.
6563 * xterm.c: Include "bitmaps/gray.xbm".
6565 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6567 Clean up __executable_start, monstartup when --enable-profiling.
6568 The following changes affect the code only when profiling.
6569 * dispnew.c (__executable_start): Rename from safe_bcopy.
6570 Define only on platforms that need it.
6571 * emacs.c: Include <sys/gmon.h> when profiling.
6572 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6573 (__executable_start): Remove decl, since lisp.h does it now.
6574 (safe_bcopy): Remove decl; no longer has that name.
6575 (main): Coalesce #if into single bit of code, for simplicity.
6576 Cast pointers to uintptr_t, since standard libraries want integers

6605 Do not create empty overlays with the evaporate property (Bug#9642).
6606 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6607 Bug#9642, but explicitly check that the buffer the overlay would
6608 be moved to is live and rearrange lines to make sure that errors
6609 will not put the overlay in an inconsistent state.
6610 (Fdelete_overlay): Cosmetics.
6612 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6614 * w32term.c (my_bring_window_to_top): New function.
6615 (x_raise_frame): Use handle returned by DeferWindowPos, which
6616 could be different from the original one.

6620 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6621 by calling BringWindowToTop.
6623 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6624 (WM_EMACS_END): Increase by one.
6626 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6628 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6629 This avoids undefined behavior that might cause the eassert
6630 to not catch an out-of-range value.
6632 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6634 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

6644 when referring to sectname field in printf format.
6646 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
6648 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6649 Only r_alloc_inhibit_buffer_relocation needed to be added;
6650 the others were already declared.
6652 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6653 before checking whether it's out of range. Put the check inside
6655 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6657 2012-05-27 Ken Brown <kbrown@cornell.edu>
6659 * callproc.c (Fcall_process): Restore a line that was accidentally
6660 commented out in the 2011-02-13 change (bug#11547).

6665 defined on ralloc.c.
6667 * buffer.c [REL_ALLOC]: Remove prototypes of

6669 they are now on lisp.h.
6671 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6673 * search.c (search_buffer): Use it to inhibit relocation of buffer
6674 text while re_search_2 is doing its job, because re_search_2 is
6675 passed C pointers to buffer text. (Bug#11519)
6677 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6680 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6681 state after an additional call to move_it_in_display_line_to, keep
6682 the values of it->max_ascent and it->max_descent found for the
6684 (pos_visible_p): Revert the comparison against bottom_y to what it
6685 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
6688 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6690 Fix coding-related core dumps with gcc -ftrapv.
6691 The code was computing A - B, where A and B are pointers, and B is
6692 random garbage. This can lead to core dumps on platforms that
6693 have special pointer registers, and it also leads to core dumps on
6694 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6695 A - B only when B is initialized properly.
6696 * coding.c (coding_set_source, coding_set_destination): Return void.
6697 (coding_change_source, coding_change_destinations): New functions,
6698 with the old behaviors of coding_set_source and coding_set_destination.
6699 All callers that need an offset changed to use these new functions.

6703 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
6705 2012-05-26 Eli Zaretskii <eliz@gnu.org>

6708 * xdisp.c (draw_row_with_mouse_face):
6709 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6711 * w32console.c: Include window.h.
6712 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6714 (initialize_w32_display): Initialize mouse-highlight data.
6716 * w32inevt.c: Include termchar.h and window.h.
6717 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6718 moves, call note_mouse_highlight. If help_echo changed, call
6719 gen_help_event to produce help-echo message in the echo area.
6720 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6723 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6725 * lread.c (read1): Simplify slightly to avoid an overflow warning
6726 with GCC 4.7.0 on x86-64.
6728 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6730 * bidi.c (bidi_mirror_char): Revert last change: an int is
6731 definitely wide enough here.

6745 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6746 (allocate_pseudovector):
6747 Use int, not EMACS_INT, where int is wide enough.
6748 (inhibit_garbage_collection, Fgarbage_collect):
6749 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6750 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
6751 int might not be wide enough.
6752 (bidi_cache_search, bidi_cache_find, bidi_init_it)

6755 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
6756 (bidi_level_of_next_char, bidi_move_to_visually_next):
6757 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6758 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
6759 (Fkill_buffer, Fset_buffer_major_mode)
6760 (advance_to_char_boundary, Fbuffer_swap_text)
6761 (Fset_buffer_multibyte, overlays_at, overlays_in)
6762 (overlay_touches_p, struct sortvec, record_overlay_string)
6763 (overlay_strings, recenter_overlay_lists)

6767 (Foverlay_recenter, last_overlay_modification_hooks_used)
6768 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6769 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6770 (validate_region): Omit unnecessary test for b <= e,
6771 since that's guaranteed by the previous test.
6772 (adjust_overlays_for_delete): Avoid pos + length overflow.
6773 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6774 (report_overlay_modification):

6776 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
6777 Omit pointer cast, which isn't needed anyway, and doesn't work
6778 after the EMACS_INT -> ptrdiff_t change.
6779 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
6780 * buffer.h: Adjust decls to match defn changes elsewhere.
6781 (struct buffer_text, struct buffer):
6782 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6783 Use EMACS_INT, not int, where int might not be wide enough.
6784 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
6785 not int, to avoid needless 32-bit limit on 64-bit hosts.
6786 (exec_byte_code): Use tighter memory-full test, one that checks
6787 for alloca overflow. Don't compute the address of the object just
6788 before an array, as that's not portable. Use EMACS_INT, not
6789 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
6790 * callint.c (Fcall_interactively):
6791 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6792 * callproc.c (call_process_kill, Fcall_process):
6793 Don't assume pid_t fits into an Emacs fixnum.
6794 (call_process_cleanup, Fcall_process, child_setup):

6804 (casify_object): Avoid integer overflow when overallocating buffer.
6805 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

6808 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6809 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6810 integers are now checked earlier. All uses replaced with XINT.
6812 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6813 For CCL_MapSingle, check that content and value are in int range.
6814 (ccl_driver, Fregister_code_conversion_map):
6815 Check that Vcode_version_map_vector is a vector.
6816 (resolve_symbol_ccl_program): Check that vector header is in range.
6817 Always copy the vector, so that we can check its contents reliably
6818 now rather than having to recheck each instruction as it's being
6819 executed. Check that vector words fit in 'int'.
6820 (ccl_get_compiled_code, Fregister_ccl_program)
6821 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6822 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

6824 contents are in range.
6825 (Fccl_execute_on_string): Check that status is in range.
6826 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
6827 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
6828 Accept and return EMACS_INT, not int, because callers can pass values

6851 that's not true for gb10830 4-byte on a 32-bit host. Allow
6852 invalid_code to be a cons, for the same reason. Require code_offset
6853 to be a character. Avoid int overflow if max_char is close

6856 this is intended anyway and avoids some undefined behavior.

6858 INDEX_TO_CODE_POINT, as that's what it expects.
6859 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.

6863 integer-overflow issues.

6866 where the argument is EMACS_INT, and this behavior is not intended.
6867 * chartab.c (Fmake_char_table, Fset_char_table_range)
6868 (uniprop_get_decoder, uniprop_get_encoder):
6869 Don't assume fixnum fits in int.
6870 * cmds.c (move_point): New function, that does the gist of
6871 Fforward_char and Fbackward_char, but does so while checking
6872 for integer overflow more accurately.

6874 (Fforward_line, Fend_of_line, internal_self_insert)
6875 (internal_self_insert):

7499 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7500 (merge_faces): Use int, not EMACS_INT, where int is wide enough.
7501 * xfns.c (x_set_menu_bar_lines, x_set_tool_bar_lines, x_icon_verify)
7503 Check that fixnums are in proper range for system types.
7504 (Fx_create_frame, x_create_tip_frame, Fx_show_tip)
7505 (Fx_hide_tip, Fx_file_dialog, Fx_select_font):
7506 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7507 (Fx_change_window_property): Don't assume fixnums fit in int.
7508 * xfont.c (xfont_chars_supported):
7509 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

7513 * xml.c (parse_region):
7514 * xrdb.c (magic_file_p):
7515 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

7517 (x_get_local_selection, x_reply_selection_request)
7518 (x_handle_selection_request, wait_for_property_change):
7519 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7520 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
7521 short is wide enough.
7522 (x_send_client_event): Don't assume fixnum fits in int.
7523 * xterm.c (x_x_to_emacs_modifiers):
7524 Don't assume EMACS_INT overflows nicely into int.
7525 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
7527 (handle_one_xevent): NATNUMP can eval its arg twice.
7528 (x_connection_closed):
7529 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7530 * xterm.h: Adjust decls to match defn changes elsewhere.
7531 (struct scroll_bar): Use struct vectorlike_header
7532 rather than rolling our own approximation.
7533 (SCROLL_BAR_VEC_SIZE): Remove; not used.
7535 2012-05-25 Glenn Morris <rgm@gnu.org>
7537 * lisp.mk (lisp): Update for more files being compiled now.
7539 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>

7542 (read_pure): Remove var.
7543 (unreadpure): Remove function.
7544 (readevalloop): Don't call read_list with -1 flag.
7545 (read1, read_vector): Don't test read_pure any more.
7546 (read_list): Simplify.
7548 * fileio.c, character.h: Minor style tweaks.
7550 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
7552 * window.h (clip_changed): Remove useless declaration.
7554 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
7556 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
7557 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
7559 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
7562 This directory predates autoconf and is no longer needed nowadays.
7563 Move its few remaining bits of functionality to where they're needed.
7564 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
7565 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:

7569 * lisp.h (USE_LSB_TAG):
7570 * mem-limits.h (EXCEEDS_LISP_PTR):
7571 Use VAL_MAX, not VALBITS, in #if.
7572 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
7573 (EMACS_UINT): Define unconditionally now.
7574 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
7575 (BITS_PER_EMACS_INT): New constants, replacing
7576 what used to be in config.h, but not useful in #if.
7577 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
7578 define them any more.
7579 (VAL_MAX): New macro.
7581 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
7582 BITS_PER_EMACS_INT, in #if.
7583 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
7584 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
7585 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
7586 * s/ms-w32.h (DATA_START):
7587 Move here from removed file m/intel386.h.
7588 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
7589 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
7591 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
7593 Assume C89 or later.
7594 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

7601 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
7602 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
7603 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
7604 * xterm.c (input_signal_count): Assume volatile works.
7606 2012-05-21 Ken Brown <kbrown@cornell.edu>
7608 * xgselect.c (xg_select): Fix first argument in call to 'select'
7611 2012-05-20 Ken Brown <kbrown@cornell.edu>
7613 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
7614 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
7616 2012-05-19 Ken Brown <kbrown@cornell.edu>
7618 * xfns.c (x_in_use): Remove `static' qualifier.
7619 * xterm.h (x_in_use): Declare.
7620 * xgselect.c: Include xterm.h.
7621 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
7622 and `display_arg' (bug#9754).
7624 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
7626 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
7628 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
7629 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
7631 2012-05-18 Eli Zaretskii <eliz@gnu.org>
7633 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
7635 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
7636 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
7638 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
7639 reference to image_cache->refcount.
7640 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
7642 2012-05-17 Juri Linkov <juri@jurta.org>
7644 * search.c (Fword_search_regexp, Fword_search_backward)
7645 (Fword_search_forward, Fword_search_backward_lax)
7646 (Fword_search_forward_lax): Move functions to isearch.el
7647 (bug#10145, bug#11381).
7649 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
7651 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
7653 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
7655 * lread.c (init_obarray): Declare Qt and Qnil as special.
7657 2012-05-14 Glenn Morris <rgm@gnu.org>
7659 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
7660 Put "libexec" before "bin", for the sake of init_callproc_1.
7662 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7664 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
7666 * unexaix.c: Port to more-recent AIX compilers.
7667 (report_error, report_error_1, make_hdr, copy_sym)
7668 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
7669 Make arguments const char *, not char *, to avoid violations of C
7670 standard and to fix some AIX warnings reported by Gilles Pion.
7672 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7674 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
7675 already have overlays loaded.
7676 (handle_single_display_spec): Before returning without displaying
7677 fringe bitmap, synchronize the bidi iterator with the main display
7678 iterator, by calling iterate_out_of_display_property.
7679 (iterate_out_of_display_property): Detect buffer iteration by
7680 testing that it->string is a Lisp string.
7681 (get_next_display_element): When the current object is exhausted,
7682 and there's something on it->stack, call set_iterator_to_next to
7683 proceed with what's on the stack, instead of returning zero.
7684 (set_iterator_to_next): If called at the end of a Lisp string,
7685 proceed to consider_string_end without incrementing string
7686 position. Don't increment display vector index past the end of
7687 the display vector. (Bug#11417)
7688 (pos_visible_p): Don't report a position visible when move_it_to
7689 stopped at the last line of window, which happens to be scanned
7690 backwards by the bidi iteration. (Bug#11464)
7692 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7694 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7695 and right-margin display specs even if the spec is invalid or we
7696 are on a TTY, and thus unable to display on the fringes.
7697 That's because the text with the property will not be displayed anyway,
7698 so we need to signal to the caller that this is a "replacing"
7699 display spec. This fixes display when the spec is invalid or we
7702 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7704 * unexaix.c (make_hdr): Fix typo in prototype.
7705 This bug broke the build on AIX. Problem reported by Gilles Pion.
7707 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
7709 * keyboard.c (kbd_buffer_get_event): Read special events also in
7710 batch mode. (Bug#11415)
7712 2012-05-12 Glenn Morris <rgm@gnu.org>
7714 * ns.mk: Update for ns_appbindir no longer having trailing "/".
7716 2012-05-12 Eli Zaretskii <eliz@gnu.org>
7718 * lisp.mk (lisp): Add newcomment.elc.
7720 2012-05-12 Glenn Morris <rgm@gnu.org>
7722 * Makefile.in (MKDIR_P): New, set by configure.
7723 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
7725 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
7727 Remove unused function hourglass_started.
7728 * dispextern.h (hourglass_started):
7729 * w32fns.c (hourglass_started):
7730 * xdisp.c (hourglass_started): Remove.
7732 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7734 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7735 Update dependencies.
7737 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7739 * xgselect.c (xg_select): Put maxfds+1 into a var.
7740 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
7742 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7744 2012-05-10 Dave Abrahams <dave@boostpro.com>
7746 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7747 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7749 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7751 * dbusbind.c (xd_registered_buses): New internal Lisp object.
7752 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7753 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7754 Initialize xd_registered_buses.
7756 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7758 Untag more efficiently if USE_LSB_TAG.
7759 This is based on a proposal by YAMAMOTO Mitsuharu in
7760 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7761 For an admittedly artificial (nth 8000 longlist) benchmark on
7762 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7763 Emacs's overall text size by 1%.
7764 * lisp.h (XUNTAG): New macro.
7765 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7766 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7767 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7768 * eval.c (Fautoload):
7769 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7770 * frame.h (XFRAME): Use XUNTAG.
7772 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7773 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7774 Remove unportable assumptions about print widths of types like
7776 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7777 intptr_t when converting between pointer and integer, to avoid GCC
7778 warnings about wrong width.
7780 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7782 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7783 stack for each reader_thread, instead of defaulting to 8MB
7784 determined by the linker. This avoids failures in creating
7785 subprocesses on Windows 7, see the discussion in this thread:
7786 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7788 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7790 Fix up display of the *Minibuf-0* buffer in the mini window.
7791 * keyboard.c (read_char): Don't clear the echo area if there's no
7793 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7794 contents of *Minibuf-0*) if there's no message displayed in its stead.
7796 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7798 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7801 2012-05-06 Chong Yidong <cyd@gnu.org>
7803 * lisp.mk (lisp): Update.
7805 2012-05-05 Jim Meyering <meyering@redhat.com>
7807 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7809 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7811 * data.c (PUT_ERROR): New macro.
7812 (syms_of_data): Use it. Add new error type `user-error'.
7813 * undo.c (user_error): New function.
7814 (Fprimitive_undo): Use it.
7815 * print.c (print_error_message): Adjust print style for `user-error'.
7816 * keyboard.c (user_error): New function.
7817 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7819 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7821 Do not limit current-time-string to years 1000..9999.
7822 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7823 (Fcurrent_time_string): Support any year that is supported by the
7824 underlying localtime representation. Don't use asctime, as it
7825 has undefined behavior for years outside the range -999..9999.
7827 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7829 Fix race conditions involving setenv, gmtime, localtime, asctime.
7830 Without this fix, interrupts could mess up code that uses these
7831 nonreentrant functions, since setting TZ invalidates existing
7832 tm_zone or tzname values, and since most of these functions return
7833 pointers to static storage.
7834 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7835 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7836 Grow the critical sections to include not just invoking
7837 localtime/gmtime, but also accessing these functions' results
7838 including their tm_zone values if any, and any related TZ setting.
7839 (format_time_string): Last arg is now struct tm *, not struct tm **,
7840 so that the struct tm is saved in the critical section.
7841 All callers changed. Simplify allocation of initial buffer, partly
7842 motivated by the fact that memory allocation needs to be outside
7843 the critical section.
7845 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7847 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7848 with RESET_INTERVAL.
7850 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7851 Remove duplicated buffer name initialization.
7853 2012-05-02 Jim Meyering <jim@meyering.net>
7855 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7857 * xfns.c (x_window): Use xstrdup (Bug#11375).
7859 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7861 * xdisp.c (pos_visible_p): If already at a newline from the
7862 display string before the 'while' loop, don't walk back the glyphs
7863 from it3.glyph_row. Solves assertion violation when the display
7864 string begins with a newline (egg.el). (Bug#11367)
7866 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7868 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7871 2012-05-01 Glenn Morris <rgm@gnu.org>
7873 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7874 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7875 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7876 All were removed before 23.1.
7878 * dispnew.c: Remove HAVE_LIBNCURSES test;
7879 it is always true on relevant platforms.
7881 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7882 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7884 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
7886 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
7888 * .gdbinit (xpr): Remove checks for no longer existing misc types.
7889 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
7892 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
7894 Do not avoid creating empty evaporating overlays (Bug#9642).
7895 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7896 That is, do not delete an evaporating overlay if it becomes
7897 empty after its bounds are adjusted to fit within its buffer.
7898 This fix caused other problems, and I'm reverting it until we get
7899 to the bottom of them.
7901 2012-04-27 Chong Yidong <cyd@gnu.org>
7903 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7905 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7907 * xdisp.c (pos_visible_p): If the window start position is beyond
7908 ZV, start the display from buffer beginning. Prevents assertion
7909 violation in init_iterator when the minibuffer window is scrolled
7912 * window.c (window_scroll_pixel_based): Likewise.
7914 2012-04-27 Chong Yidong <cyd@gnu.org>
7916 * keymap.c (where_is_internal): Doc fix (Bug#10872).
7918 2012-04-27 Glenn Morris <rgm@gnu.org>
7920 * fileio.c (Fcopy_file, Fset_file_selinux_context):
7921 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
7923 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7925 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
7926 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
7928 2012-04-26 Eli Zaretskii <eliz@gnu.org>
7930 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7931 display element, check also the underlying string or buffer
7932 character. (Bug#11341)
7934 * w32menu.c: Include w32heap.h.
7935 (add_menu_item): If the call to AppendMenuW (via
7936 unicode_append_menu) fails, disable Unicode menus only if we are
7937 running on Windows 9X/Me.
7939 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7941 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
7942 (xgetint): Add missing shift for LSB tags.
7944 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7946 * keyboard.c (read_char): Don't wipe echo area for select window
7947 events: These might get delayed via `mouse-autoselect-window'

7960 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7962 Do not create empty overlays with the evaporate property (Bug#9642).
7963 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7964 if it becomes empty after its bounds are adjusted to fit within
7965 its buffer. Without this fix, in a nonempty buffer (let ((o
7966 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7967 yields an empty overlay that has the evaporate property, which is
7968 not supposed to happen.

8072 since the two debugging options are incompatible.
8073 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
8075 (mem_init, mem_insert, mem_insert_fixup):
8076 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

8085 * sysdep.c [__FreeBSD__]: Minor cleanups.
8086 (list_system_processes, system_process_attributes) [__FreeBSD__]:
8087 Use Emacs indenting style more consistently. Avoid some casts.
8088 Use 'double' consistently rather than mixing 'float' and 'double'.

8108 (print_object): Check for cycles even when print-circle is nil and
8109 print-gensym is t, but only check print_depth if print-circle is nil.
8111 2012-04-20 Chong Yidong <cyd@gnu.org>
8113 * process.c (wait_reading_process_output): If EIO occurs on a pty,

8169 New extern decls, to avoid calling undeclared functions.
8170 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
8171 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
8172 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
8173 (NEED_MEM_INSERT): New macro.
8174 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
8175 Remove one incorrect comment and fix another.

8189 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
8190 Remove decls. This fixes an "It stinks!".

8194 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
8196 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

8212 * s/netbsd.h, s/sol2-6.h:
8213 Remove definition of GC_MARK_STACK, since the default now works.
8214 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
8215 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
8216 no longer the default.
8217 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
8219 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

8242 2012-04-11 Daniel Colascione <dancol@dancol.org>
8244 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
8245 against is gone. It's better to use vfork now so that when Cygwin
8246 gains a new, working vfork, we use it automatically (bug#10398).
8248 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

8303 2012-04-09 Eli Zaretskii <eliz@gnu.org>
8305 * xdisp.c (set_cursor_from_row): If the display string appears in
8306 the buffer at position that is closer to point than the position
8307 after the display string, display the cursor on the first glyph of
8308 the display string. Fixes cursor display when a 'display' text
8309 property immediately follows invisible text. (Bug#11094)
8311 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
8313 composite.c: use 'double' consistently
8314 * composite.c (get_composition_id): Use 'double' consistently
8315 instead of converting 'float' to 'double' and vice versa; this is
8316 easier to understand and avoids a GCC warning.
8318 2012-04-09 Glenn Morris <rgm@gnu.org>
8320 * Makefile.in: Generate leim-list with bootstrap-emacs, in

8365 [!WINDOWSNT]: New macros.
8366 (init_libxml2_functions, libxml2_loaded_p): New functions.
8367 (parse_region): Call fn_xmlCheckVersion instead of using the macro
8368 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
8369 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
8370 Calls xmlCleanupParser only if libxml2 was loaded (or statically
8372 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
8373 Call init_libxml2_functions before calling libxml2 functions.
8374 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
8376 * emacs.c: Don't include libxml/parser.h.

8390 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
8391 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
8392 about subtle differences between FETCH_CHAR* and STRING_CHAR*
8393 macros related to unification of CJK characters. For the details,

8395 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
8397 2012-04-04 Chong Yidong <cyd@gnu.org>
8399 * keyboard.c (Vdelayed_warnings_list): Doc fix.
8401 2012-04-01 Eli Zaretskii <eliz@gnu.org>
8403 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
8404 instead of alloca. (Bug#11138)
8406 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
8408 * w32menu.c (is_simple_dialog): Properly check lisp types.
8411 2012-03-31 Eli Zaretskii <eliz@gnu.org>
8413 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
8414 position we get to after a call to move_it_to fails the
8415 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
8416 only if we wind up in a string from display property. (Bug#11063)
8418 * window.c (Fdelete_other_windows_internal): Invalidate the row
8419 and column information about mouse highlight, so that redisplay
8420 restores it after reallocating the glyph matrices. (Bug#7464)
8422 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
8423 string comes from a `display' text property, use the buffer
8424 position of that property as if we actually saw that position in
8426 (move_it_by_lines): Remove the assertion that
8427 "it->current_x == 0 && it->hpos == 0" which can be legitimately
8428 violated when there's a before-string at the beginning of a line.
8431 2012-03-30 Eli Zaretskii <eliz@gnu.org>
8433 * xdisp.c (append_space_for_newline): If the default face was
8434 remapped, use the remapped face for the appended newline.
8435 (extend_face_to_end_of_line): Use the remapped default face for
8436 extending the face to the end of the line.
8437 (display_line): Call extend_face_to_end_of_line when the default
8438 face was remapped. (Bug#11068)
8440 2012-03-29 Eli Zaretskii <eliz@gnu.org>
8442 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
8444 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
8446 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
8448 2012-03-27 Glenn Morris <rgm@gnu.org>
8450 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
8453 2012-03-26 Kenichi Handa <handa@m17n.org>
8455 * dispextern.h (struct glyph): Fix previous change. Change the
8456 bit length of glyphless.ch to 25 (Bug#11082).
8458 2012-03-26 Chong Yidong <cyd@gnu.org>
8460 * keyboard.c (Vselection_inhibit_update_commands): New variable.
8461 (command_loop_1): Use it; inhibit selection update for
8462 handle-select-window too (Bug#8996).
8464 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
8466 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
8468 2012-03-25 Kenichi Handa <handa@m17n.org>
8470 * dispextern.h (struct glyph): Change the bit length of
8471 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
8473 2012-03-24 Eli Zaretskii <eliz@gnu.org>
8475 * s/ms-w32.h (tzname): Include time.h before redirecting to
8476 _tzname. Fixes the MSVC build. (Bug#9960)
8478 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
8480 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
8483 * xterm.c (XTread_socket): Only modify handling_signal if
8484 !SYNC_INPUT. (Bug#11080)
8486 2012-03-23 Eli Zaretskii <eliz@gnu.org>
8488 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
8489 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
8490 when fetching a multibyte character consumes more bytes than
8491 CHAR_BYTES returns, due to unification of CJK characters in
8492 string_char. (Bug#11073)
8494 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
8496 * process.c (wait_reading_process_output): Handle pty disconnect
8497 by refraining from sending oneself a SIGCHLD (bug#10933).
8499 2012-03-22 Chong Yidong <cyd@gnu.org>
8501 * dispextern.h (struct it): New member string_from_prefix_prop_p.
8503 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
8504 Mark string as coming from a prefix property.
8505 (handle_face_prop): Use default face for prefix strings (Bug#4281).
8506 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
8508 2012-03-21 Chong Yidong <cyd@gnu.org>
8510 * xfaces.c (Vface_remapping_alist): Doc fix.
8512 2012-03-20 Eli Zaretskii <eliz@gnu.org>
8514 * w32proc.c (Fw32_set_console_codepage)
8515 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
8518 2012-03-20 Chong Yidong <cyd@gnu.org>
8520 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
8521 to reflect default non-nil value of redisplay-dont-pause.
8523 2012-03-19 Kenichi Handa <handa@m17n.org>
8525 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
8526 it fit in a valid range (Bug#11003).
8528 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8530 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8531 that is not from display property, accept the row as a "cursor
8532 row" if one of the string's character has a non-nil `cursor'
8533 property. Fixes cursor positioning when there are newlines in
8534 overlay strings, e.g. in icomplete.el. (Bug#11035)
8536 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
8538 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
8540 2012-03-12 Chong Yidong <cyd@gnu.org>
8542 * eval.c (inhibit_lisp_code): Rename from
8543 inhibit_window_configuration_change_hook; move from window.c.
8545 * xfns.c (unwind_create_frame_1, Fx_create_frame):
8546 * window.c (run_window_configuration_change_hook)
8547 (syms_of_window): Callers changed.
8549 2012-03-11 Chong Yidong <cyd@gnu.org>
8551 * keymap.c (Fkey_description): Doc fix (Bug#9700).
8553 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).

8558 is visible (Bug#10955).
8560 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
8562 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
8564 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
8566 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
8567 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8570 2012-03-03 Glenn Morris <rgm@gnu.org>
8572 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
8574 2012-03-02 Eli Zaretskii <eliz@gnu.org>
8576 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
8577 position past the first glyph_row that ends at ZV. (Bug#10902)
8578 (redisplay_window, next_element_from_string): Fix typos in
8580 (redisplay_window): Pass to move_it_vertically the margin in
8581 pixels, not in screen lines.
8583 2012-03-02 Glenn Morris <rgm@gnu.org>
8585 * buffer.c (buffer-list-update-hook): Doc fix.
8587 2012-02-29 Eli Zaretskii <eliz@gnu.org>
8589 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
8590 push_it before setting up the iterator for the first overlay
8591 string, even if we have an empty string loaded.
8592 (next_overlay_string): If there's an empty string on the iterator
8593 stack, pop the stack. (Bug#10903)
8595 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8597 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8598 Suggested by Stefan Monnier in
8599 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8600 * alloc.c (widen_to_Lisp_Object): New static function.
8601 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8602 and widening them to Lisp_Objects. This would work even if
8603 USE_LSB_TAG is defined and wide integers are used, which might
8604 happen in a future version of Emacs.
8606 2012-02-25 Chong Yidong <cyd@gnu.org>
8608 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
8611 * xselect.c (Fx_selection_exists_p): Doc fix.
8612 (x_clipboard_manager_save_all): Print an informative message
8613 before saving to clipboard manager.
8615 2012-02-24 Chong Yidong <cyd@gnu.org>
8617 * keyboard.c (process_special_events): Handle all X selection
8618 requests in kbd_buffer, not just the next one (Bug#8869).
8620 2012-02-23 Chong Yidong <cyd@gnu.org>
8622 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
8623 call when setting menu-bar-lines and tool-bar-lines parameters.
8624 (unwind_create_frame_1): New helper function.
8626 * window.c (inhibit_window_configuration_change_hook): New var.
8627 (run_window_configuration_change_hook): Obey it.
8628 (syms_of_window): Initialize it.
8630 2012-02-22 Chong Yidong <cyd@gnu.org>
8632 * xterm.c (x_draw_image_relief): Add missing type check for
8633 Vtool_bar_button_margin (Bug#10743).
8635 2012-02-21 Chong Yidong <cyd@gnu.org>
8637 * fileio.c (Vfile_name_handler_alist): Doc fix.
8639 * buffer.c (Fget_file_buffer): Protect against invalid file
8640 handler return value.
8642 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
8644 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
8645 when computing $valmask.
8647 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8648 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8649 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8650 It's useless in that case, and it can cause problems on hosts
8651 that allocate halves of EMACS_INT values separately.
8652 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8653 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8654 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8655 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8656 it avoids undefined behavior on hosts where shifting right by more
8657 than the word width has undefined behavior.
8659 2012-02-19 Chong Yidong <cyd@gnu.org>
8661 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
8662 (Funhandled_file_name_directory, Ffile_name_as_directory)
8663 (Fdirectory_file_name, Fexpand_file_name)
8664 (Fsubstitute_in_file_name): Protect against invalid file handler
8665 return values (Bug#10845).
8667 2012-02-18 Eli Zaretskii <eliz@gnu.org>
8669 * .gdbinit (pitx): Fix incorrect references to fields of the
8672 2012-02-17 Chong Yidong <cyd@gnu.org>
8674 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
8676 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
8678 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
8679 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
8681 2012-02-15 Chong Yidong <cyd@gnu.org>
8683 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
8684 marked as special. Also, starting docstrings with * is obsolete.
8686 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
8688 * gnutls.c (emacs_gnutls_write): Fix last change.
8690 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

8695 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
8697 * keymap.c (Fsingle_key_description): Handle char ranges.
8699 2012-02-12 Chong Yidong <cyd@gnu.org>
8701 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
8702 as that creates a dangerous corner case.
8704 * window.c (Fdelete_window_internal): Invalidate the mouse
8705 highlight (Bug#9904).
8707 2012-02-12 Glenn Morris <rgm@gnu.org>
8709 * xselect.c (Fx_own_selection_internal)
8710 (Fx_get_selection_internal, Fx_disown_selection_internal)
8711 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
8712 * nsselect.m (Fx_own_selection_internal)
8713 (Fx_disown_selection_internal, Fx_selection_exists_p)
8714 (Fx_selection_owner_p, Fx_get_selection_internal):
8715 Sync docs and argument specs with the xselect.c versions.
8717 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
8719 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
8721 2012-02-11 Eli Zaretskii <eliz@gnu.org>
8723 * w32select.c (Fx_selection_exists_p): Sync doc string and
8724 argument list with xselect.c. (Bug#10783)
8726 * w16select.c (Fx_selection_exists_p): Sync doc string and
8727 argument list with xselect.c. (Bug#10783)
8729 2012-02-10 Glenn Morris <rgm@gnu.org>

8733 2012-02-09 Kenichi Handa <handa@m17n.org>
8735 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
8737 2012-02-07 Chong Yidong <cyd@gnu.org>
8739 * buffer.c (Fbuffer_local_variables)
8740 (buffer_lisp_local_variables): Handle unbound vars correctly;
8741 don't let Qunbound leak into Lisp.
8743 2012-02-07 Glenn Morris <rgm@gnu.org>
8745 * image.c (Fimagemagick_types): Doc fix.
8747 * image.c (imagemagick-render-type): Change it from a lisp object
8748 to an integer. Move the doc here from the lisp manual.

8751 2012-02-06 Chong Yidong <cyd@gnu.org>
8753 * doc.c (store_function_docstring): Avoid applying docstring of
8754 alias to base function (Bug#2603).
8756 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
8758 * .gdbinit (pp1, pv1): Remove redundant defines.
8761 2012-02-04 Chong Yidong <cyd@gnu.org>
8763 * nsterm.m: Declare a global (Bug#10694).
8765 2012-02-04 Eli Zaretskii <eliz@gnu.org>
8767 * w32.c (get_emacs_configuration_options):
8768 Include --enable-checking, if specified, in the return value.

8777 * keyboard.c (adjust_point_for_property): Don't position point
8778 before BEGV. (Bug#10696)
8780 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
8782 Handle overflow when computing char display width (Bug#9496).
8783 * character.c (char_width): Return EMACS_INT, not int.
8784 (char_width, c_string_width): Check for overflow when
8785 computing the width; this is possible now that individual
8786 characters can have unbounded width. Problem introduced
8787 by merge from Emacs 23 on 2012-01-19.
8789 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
8791 * dbusbind.c (Fdbus_register_method): Mention the return value

8804 2012-02-02 Kenichi Handa <handa@m17n.org>
8806 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
8807 0, do not call append_composite_glyph.
8809 2012-02-02 Kenichi Handa <handa@m17n.org>
8811 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
8813 (x_produce_glyphs): If the component of a composition is a null
8814 string, set it->pixel_width to 1 to avoid zero-width glyph.
8816 2012-02-01 Eli Zaretskii <eliz@gnu.org>
8818 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
8819 first 2 arguments are identical. This makes inserting large
8820 output from a subprocess an order of magnitude faster on
8821 MS-Windows, where all sbrk'ed memory is always contiguous.
8823 2012-01-31 Glenn Morris <rgm@gnu.org>
8825 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

8861 2012-01-21 Chong Yidong <cyd@gnu.org>
8863 * floatfns.c (Fcopysign): Make the second argument non-optional,
8864 since nil is not allowed anyway.
8866 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
8868 * process.c (read_process_output): Use p instead of XPROCESS (proc).
8869 (send_process): Likewise.
8871 2012-01-19 Martin Rudalics <rudalics@gmx.at>
8873 * window.c (save_window_save, Fcurrent_window_configuration)

8877 2012-01-19 Kenichi Handa <handa@m17n.org>
8879 * character.c (char_width): New function.
8880 (Fchar_width, c_string_width, lisp_string_width):
8881 Use char_width (Bug#9496).
8883 2012-01-16 Martin Rudalics <rudalics@gmx.at>
8885 * window.c (Vwindow_persistent_parameters): New variable.
8886 (Fset_window_configuration, save_window_save): Handle persistent
8889 2012-01-14 Eli Zaretskii <eliz@gnu.org>
8891 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid
8892 thrashing the stack of the thread. (Bug#9087)
8894 2012-01-12 Paul Eggert <eggert@cs.ucla.edu>
8896 * xdisp.c (rows_from_pos_range): Add parens as per gcc -Wparentheses.
8898 2012-01-11 Eli Zaretskii <eliz@gnu.org>

9436 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
9437 Otherwise, valgrind does not work on some platforms.
9438 Problem reported by Andreas Schwab in
9439 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
9440 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
9441 is set, removing the need for VIRT_ADDRESS_VARIES.
9442 (PURE_P): Use a more-efficient implementation that needs just one
9443 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
9444 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
9445 to 4 (xorl, subq, cmpq, setbe).
9446 * alloc.c (pure): Always extern now, since that's the
9447 VIRT_ADDR_VARIES behavior.
9448 (PURE_POINTER_P): Use a single comparison, not two, for
9449 consistency with the new puresize.h.
9450 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

9458 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
9459 behave as if the cursor position were at the window margin.
9461 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
9462 and the cursor position is out of bounds, behave as if the cursor
9463 position were at the window margin. (Bug#10075)
9465 2011-11-18 Chong Yidong <cyd@gnu.org>
9467 * window.c (Fwindow_combination_limit): Make first argument

9490 (compute_line_metrics): Call row_hash, instead of computing the
9493 * dispnew.c (verify_row_hash): Call row_hash for computing the
9494 hash code of a row, instead of duplicating code from xdisp.c.
9496 * dispextern.h (row_hash): Add prototype.

9532 * image.c (imagemagick_load_image): Fix typo.
9534 2011-11-14 Eli Zaretskii <eliz@gnu.org>
9536 * xdisp.c (display_line): Move the call to
9537 highlight_trailing_whitespace before the call to
9538 compute_line_metrics, since the latter needs to see the final
9539 faces of all the glyphs to compute ROW's hash value.
9540 Fixes assertion violations in row_equal_p. (Bug#10035)
9542 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

9549 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
9550 with user-defined heap size. Bump the default size of the temacs
9551 heap to 27MB, to avoid memory warning when running temacs.
9552 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
9554 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

9601 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
9603 Avoid some portability problems by eschewing 'extern inline' functions.
9604 The trivial performance wins aren't worth the portability hassles; see
9605 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
9607 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

9609 (window_box_right, window_box_right_offset): Undo previous change,
9610 by removing the "extern"s.
9611 * intervals.c (adjust_intervals_for_insertion)
9612 (adjust_intervals_for_deletion): Undo previous change,
9613 making these static again.
9614 (offset_intervals, temp_set_point_both, temp_set_point)
9615 (copy_intervals_to_string): No longer inline.
9616 * xdisp.c (window_text_bottom_y, window_box_width)

9689 (static_offset_intervals): Remove.
9690 (offset_intervals): Rewrite using the old contents of
9691 static_offset_intervals. The old version didn't conform to C99
9692 because an extern inline function contained a reference to an

9865 so that this new function doesn't get optimized away by a
9866 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
9868 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
9870 * frame.h (MOUSE_HL_INFO): Remove excess parens.
9872 2011-10-29 Eli Zaretskii <eliz@gnu.org>
9874 Fix the `xbytecode' command.
9875 * .gdbinit (xprintbytestr): New command.
9876 (xwhichsymbols): Rename from `which'; all callers changed.
9877 (xbytecode): Print the byte-code string as well.
9879 2011-10-29 Kim Storm <storm@cua.dk>
9881 * alloc.c (which_symbols): New function.
9883 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
9885 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
9888 2011-10-29 Glenn Morris <rgm@gnu.org>
9890 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
9891 Not clear what it was for, and it causes various bugs. (Bug#9839)
9893 2011-10-28 Eli Zaretskii <eliz@gnu.org>
9895 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
9896 possible random value that matches one of those tested as
9897 condition to clear the mouse face.
9899 2011-10-28 Chong Yidong <cyd@gnu.org>
9901 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
9903 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
9905 * window.c (make_window): Initialize phys_cursor_on_p.
9907 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
9909 * lisp.h (struct Lisp_Symbol): Update comments.
9911 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
9913 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
9915 2011-10-28 Eli Zaretskii <eliz@gnu.org>
9917 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
9918 <oslsachem@gmail.com> for helping to debug this.
9920 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
9921 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
9922 (g_b_init_get_glyph_outline_w): New static variables.
9923 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
9924 (GetGlyphOutlineW_Proc): New typedefs.
9925 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
9926 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
9928 (w32font_open_internal, compute_metrics):
9929 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
9930 instead of calling the "wide" APIs directly.
9932 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
9934 * w32.h (syms_of_w32font): Add prototype.
9936 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9938 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
9939 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
9940 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
9941 (Fmove_to_window_line): Doc fix.
9943 2011-10-27 Chong Yidong <cyd@gnu.org>
9945 * process.c (make_process): Set gnutls_state to NULL.
9947 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
9948 non-NULL, regardless of GNUTLS_INITSTAGE.
9949 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
9950 an error. Set process slots as soon as we allocate them.
9952 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
9954 2011-10-27 Chong Yidong <cyd@gnu.org>
9956 * gnutls.c (emacs_gnutls_deinit): New function.
9957 Deallocate credentials structures as well as calling gnutls_deinit.
9958 (Fgnutls_deinit, Fgnutls_boot): Use it.
9960 * process.c (make_process): Initialize GnuTLS credentials to NULL.
9961 (deactivate_process): Call emacs_gnutls_deinit.
9963 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9965 * image.c (x_create_x_image_and_pixmap):
9966 * w32.c (sys_rename, w32_delayed_load):
9967 * w32font.c (fill_in_logfont):
9968 * w32reg.c (x_get_string_resource): Silence compiler warnings.
9970 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
9972 * w32fns.c (w32_default_color_map): New function,
9973 extracted from Fw32_default_color_map.
9974 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
9976 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
9978 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
9980 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
9982 * keyboard.c (test_undefined): New function (bug#9751).
9983 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
9985 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
9987 * sysdep.c (init_sys_modes): Fix the check for the controlling
9988 terminal (Bug#6649).
9990 2011-10-20 Eli Zaretskii <eliz@gnu.org>
9992 * dispextern.h (struct bidi_it): New member next_en_type.
9994 * bidi.c (bidi_line_init): Initialize the next_en_type member.
9995 (bidi_resolve_explicit_1): When next_en_pos is valid for the
9996 current character, check also for next_en_type being WEAK_EN.
9997 (bidi_resolve_weak): Don't enter the expensive loop if the current
9998 position is before next_en_pos. Record the bidi type of the first
9999 non-ET, non-BN character we find, in addition to its position.
10000 (bidi_level_of_next_char): Invalidate next_en_type when
10001 next_en_pos is over-stepped.
10003 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
10005 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
10006 * editfns.c: Rewrite current-time-zone so that it invokes
10007 the equivalent of (format-time-string "%Z") to get the time zone name.
10008 This fixes a bug when the time zone name contains characters that
10009 need converting from the system time locale to Emacs internal format.
10010 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
10011 that patch fixed format-time-string to do the conversion, but
10012 I forgot to fix current-time-zone.
10013 (format_time_string): New function, containing most of
10014 what Fformat_time_string used to contain.
10015 (Fformat_time_string): Rewrite in terms of format_time_string.
10016 This doesn't change this function's behavior.
10017 (current-time-zone): Rewrite to use format_time_string.
10018 This fixes the bug reported by Michael Schierl in
10019 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
10020 Jason Rumney's 2007-06-07 change worked around this bug, but
10022 * systime.h (tzname, timezone): Remove no-longer-used declarations.
10024 2011-10-19 Eli Zaretskii <eliz@gnu.org>
10026 * xdisp.c (start_display): If the character at POS is displayed
10027 via a display vector, reset IT->current.dpvec_index to zero.
10028 (try_window_reusing_current_matrix): If a line ends in a display
10029 vector or the next line starts in a display vector, continue
10030 redrawing the window even though the character position of
10031 start_row was reached.
10034 2011-10-18 Chong Yidong <cyd@gnu.org>
10036 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
10037 with nobreak-char-display too.
10039 2011-10-18 Eli Zaretskii <eliz@gnu.org>
10041 Fix part 3 of bug#9771.
10042 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
10043 (bidi_resolve_neutral): Don't enter the expensive loop looking for
10044 non-neutral characters if the current character is a paragraph
10045 separator (a.k.a. Newline). This avoids running the same
10046 expensive loop twice, once when we consume the preceding newline
10047 and the other time when the line actually needs to be displayed.
10048 Avoid the loop when we see neutrals on the base embedding level
10049 following a character whose directionality is the same as the
10050 paragraph's. This avoids running the expensive loop when a line
10051 ends in a long sequence of neutrals, like control characters.
10052 Add assertion against STRONG_AL type. Slightly rearrange code
10053 that determines the type of a neutral given the first non-neutral
10055 (bidi_level_of_next_char): Set next_en_pos to zero when
10056 invalidating its info.
10058 2011-10-17 Eli Zaretskii <eliz@gnu.org>
10060 * xdisp.c (push_display_prop): Determine whether to record string
10061 or buffer position by IT->string, not by IT->method. Allow
10062 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
10063 (move_it_vertically_backward): Don't look for character position
10064 immediately after the newline when in a continuation line.
10067 2011-10-15 Martin Rudalics <rudalics@gmx.at>
10069 * window.c (coordinates_in_window): Rewrite and delabelize
10070 vertical border check. (Bug#5357) (Bug#9618)
10072 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
10074 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
10075 errors in XSetWindowBorder (bug#9310).
10077 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
10079 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
10080 avoid crash when xmalloc overrun checking is enabled.
10082 2011-10-13 Eli Zaretskii <eliz@gnu.org>
10084 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
10085 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
10086 cursor motion with <left> and <right> arrow keys.
10088 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
10089 some callers set that themselves.
10091 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10093 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
10094 display string and the previous row comes from the same string and
10095 is empty. (Bug#9739) (Bug#9738)
10097 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
10099 * doc.c (get_doc_string): Encode file name (bug#9735).
10101 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10103 * bidi.c (bidi_level_of_next_char):
10104 * xdisp.c (get_visually_first_element): Remove old incorrect
10105 comments regarding the Unicode Line Separator character.
10107 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
10109 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
10111 * alloc.c (Fgc_status): Do not access beyond zombies array
10112 boundary if nzombies > MAX_ZOMBIES.
10113 * alloc.c (dump_zombies): Add missing format specifier.
10115 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
10117 * xdisp.c (set_cursor_from_row): Simplify conditionals,
10118 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
10120 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
10121 Some packages use them to denote characters with modifiers.
10123 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
10125 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
10126 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
10127 matching a pp-number. Rename parameter var to var1.
10129 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
10131 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
10133 2011-10-08 Glenn Morris <rgm@gnu.org>
10135 * callint.c (Fcall_interactively): Give a more explicit error for the
10136 'c' case with a non-character input. (Bug#8479)
10138 2011-10-08 Eli Zaretskii <eliz@gnu.org>
10140 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
10142 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
10143 lines that are hscrolled on the left.
10145 * dispnew.c (buffer_posn_from_coords): Account for a possible
10146 presence of header-line. (Bug#4426)
10148 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
10150 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
10151 Don't advertise functionality which we discourage or doesn't work.
10153 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
10155 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
10156 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
10157 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
10158 this makes Emacs dump core during garbage collection on rare
10159 occasions. sizeof is obviously inferior to offsetof here, so
10160 stick with offsetof.
10161 (GC_POINTER_ALIGNMENT): New macro.
10162 (mark_memory): Omit 3rd (offset) arg; caller changed.
10163 Don't assume EMACS_INT alignment is the same as pointer alignment.
10165 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
10167 * keyboard.c (read_key_sequence_remapped): New var.
10168 (read_key_sequence): Compute remapping in the right buffer.
10169 (command_loop_1): Use read_key_sequence's remapping directly.
10171 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
10173 * dired.c (file_name_completion): Don't expand file name.
10174 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
10175 before checking file name handler.
10177 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
10178 they've been requested explicitly (bug#9591).
10180 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
10182 * keymap.c (Fsingle_key_description): Use make_specified_string
10183 instead of build_string to build string from push_key_description.
10186 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10188 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
10189 This fixes a Y2038 bug on 64-bit hosts.
10190 * buffer.c (reset_buffer):
10191 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
10192 (Fclear_buffer_auto_save_failure):
10193 Use 0, not -1, to represent an unset failure time, since time_t
10194 might not be signed.
10196 Remove dependency on glibc malloc internals.
10197 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10198 Move back here from lisp.h, but with their new implementations.
10199 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10200 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
10201 * charset.c (charset_table_init): New static var.
10202 (syms_of_charset): Use it instead of xmalloc. This removes a
10203 dependency on glibc malloc internals. See Eli Zaretskii's comment in
10204 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
10205 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10206 Move back to alloc.c.
10207 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10208 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
10210 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
10212 * nsterm.m (windowDidResize): Call x_set_window_size only when
10213 ns_in_resize is true. Otherwise set pixelwidth/height and
10214 call change_frame_size (Bug#9628).
10216 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10218 Port --enable-checking=all to Fedora 14 x86-64.
10219 * charset.c (syms_of_charset): Also account for glibc malloc's
10220 internal overhead when calculating the initial malloc maximum.
10222 Port --enable-checking=all to Fedora 14 x86.
10223 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10225 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
10226 (overrun_check_realloc, overrun_check_free):
10227 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
10228 That way, xmalloc returns a properly-aligned pointer even if
10229 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
10230 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
10231 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
10232 into account when calculating the initial malloc maximum.
10233 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10234 Move here from alloc.c, so that charset.c can use it too.
10235 Properly align; the old code wasn't right for common 32-bit hosts
10236 when configured with --enable-checking=all.
10237 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10238 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
10240 2011-09-29 Eli Zaretskii <eliz@gnu.org>
10242 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
10245 2011-09-28 Eli Zaretskii <eliz@gnu.org>
10247 * xdisp.c (compute_display_string_end): If there's no display
10248 string at CHARPOS, return -1.
10250 * bidi.c (bidi_fetch_char): When compute_display_string_end
10251 returns a negative value, treat the character as a normal
10252 character not covered by a display string. (Bug#9624)
10254 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
10256 * lread.c (Fread_from_string): Fix typo in docstring.
10258 2011-09-27 Eli Zaretskii <eliz@gnu.org>
10260 * xdisp.c (handle_invisible_prop): If invisible text ends on a
10261 newline, reseat the iterator instead of bidi-iterating there one
10262 character at a time. (Bug#9610)
10263 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
10264 TO_CHARPOS if the bidi iterator is at base embedding level.
10266 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
10268 * lread.c (readevalloop): Use correct code for NBSP.
10269 (read1): Likewise. (Bug#9608)
10271 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
10273 * dbusbind.c (Fdbus_register_signal): When service is not
10274 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
10276 2011-09-25 Glenn Morris <rgm@gnu.org>
10278 * buffer.c (truncate-lines): Doc fix.
10280 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
10282 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
10283 (Fset_window_next_buffers): Doc fix.
10285 2011-09-24 Glenn Morris <rgm@gnu.org>
10287 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
10289 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
10291 Fix minor problems found by static checking.
10292 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
10293 * indent.c (Fvertical_motion): Fix == vs = typo.
10295 2011-09-24 Eli Zaretskii <eliz@gnu.org>
10297 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
10298 Default value is now t. Doc fix.
10300 * indent.c (Fvertical_motion): Compute and apply the overshoot
10301 logic when moving up, not only when moving down. Fix the
10302 confusing name and values of the it_overshoot_expected variable;
10303 logic changes accordingly. (Bug#9254) (Bug#9549)
10305 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
10306 CHARPOS is covered by a display string which includes newlines.
10307 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
10308 is covered by a display string with embedded newlines.
10310 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
10312 * dbusbind.c (Fdbus_register_signal): Add match rule to
10313 Vdbus_registered_objects_table. (Bug#9581)
10314 (Fdbus_register_method, Vdbus_registered_objects_table):
10317 2011-09-24 Jim Meyering <meyering@redhat.com>
10319 do not ignore write error for any output size
10320 The previous change was incomplete.
10321 While it makes emacs --batch detect the vast majority of stdout
10322 write failures, errors were still ignored whenever the output size is
10323 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
10324 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
10325 && echo FAIL: ignored write error
10326 FAIL: ignored write error
10327 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
10328 && echo FAIL: ignored write error
10329 FAIL: ignored write error
10330 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
10332 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
10334 * emacs.c (Fkill_emacs): In noninteractive mode exit
10335 non-successfully if a write error occurred on stdout. (Bug#9574)
10337 2011-09-21 Eli Zaretskii <eliz@gnu.org>
10339 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
10342 * dispextern.h (struct it): Update the comment documenting what
10345 2011-09-20 Eli Zaretskii <eliz@gnu.org>
10347 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
10348 a display string, extend search for cursor position to end of row.
10349 (find_row_edges): If the row ends in a newline from a display
10350 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
10351 Handle the case of a display string with multiple newlines.
10352 (Fcurrent_bidi_paragraph_direction): Fix search for previous
10353 non-empty line. Fixes confusing cursor motion with arrow keys at
10354 the beginning of a line that starts with whitespace.
10356 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10358 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
10361 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
10363 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
10364 boolean (Bug#9154).
10366 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10368 * xdisp.c (display_line): Record maximum and minimum buffer
10369 positions even if no glyphs were produced (e.g., by a zero-width
10370 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
10371 buffer positions that will be removed from the glyph row because
10373 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
10374 column is beyond frame width: don't subtract 1 "pixel" when
10375 computing width of the stretch.
10376 (reseat_at_next_visible_line_start): Undo the change made on
10377 2011-09-17 that saved paragraph information and restored it after
10378 the call to `reseat'. (Bug#9545)
10380 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10382 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
10383 and turn window cursor on if cleared (Bug#9415).
10385 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
10387 * search.c (boyer_moore): Take unibyte characters from pattern
10388 literally. (Bug#9458)
10390 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10392 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
10394 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
10396 Fix minor problem found by static checking.
10397 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
10398 initialized, to pacify gcc -Wuninitialized.
10400 * fileio.c: Report proper errno when syscall falls.
10401 (Finsert_file_contents): Save and restore errno,
10402 so that report_file_error outputs the correct diagnostic.
10403 (Fwrite_region) [CLASH_DETECTION]: Likewise.
10405 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10407 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
10409 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10411 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
10412 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
10414 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10416 * xdisp.c (reseat_at_next_visible_line_start): Keep information
10417 about the current paragraph and restore it after the call to reseat.
10419 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
10420 (bidi_find_paragraph_start): Search back for paragraph beginning
10421 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
10422 (bidi_move_to_visually_next): Only trigger paragraph-related
10423 computations when the last character is a newline or at EOB, not
10424 just any NEUTRAL_B. (Bug#9470)
10426 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
10427 truncated lines if point is covered by a display string. (Bug#9524)
10429 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
10431 * xselect.c: Relax test for outgoing X longs (Bug#9498).
10432 (cons_to_x_long): New function.
10433 (lisp_data_to_selection_data): Use it. Correct the test for
10434 short-versus-long data; it was negated. Break out of vector
10435 loop, for efficiency, when a long datum is discovered.
10437 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
10439 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
10441 2011-09-16 Eli Zaretskii <eliz@gnu.org>
10443 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
10444 GCC PR/17406) by declaring this function with external scope.
10446 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10448 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
10449 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
10451 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
10453 * editfns.c (Fformat): Correctly handle text properties on "%%".
10455 2011-09-15 Eli Zaretskii <eliz@gnu.org>
10457 * xterm.c (x_draw_composite_glyph_string_foreground):
10458 * w32term.c (x_draw_composite_glyph_string_foreground):
10459 * term.c (encode_terminal_code):
10460 * composite.c (composition_update_it, get_composition_id):
10461 * xdisp.c (get_next_display_element)
10462 (fill_composite_glyph_string): Add comments about special meaning
10463 of TAB characters in a composition.
10465 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10467 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
10468 This occurs when processing a multibyte format.
10469 Problem reported by Wolfgang Jenker.
10471 2011-09-15 Johan Bockgård <bojohan@gnu.org>
10473 * xdisp.c (try_cursor_movement): Only check for exact match if
10474 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
10476 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10478 Remove unused external symbols.
10479 * dispextern.h (calc_pixel_width_or_height): Remove decl.
10480 * xdisp.c (calc_pixel_width_or_height): Now static.
10481 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
10482 * indent.c (check_display_width):
10483 * w32term.c: Fix comment to match code.
10484 * xterm.c, xterm.h (x_catching_errors): Remove.
10486 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10488 * xselect.c: Use signed conversions more consistently (Bug#9498).
10489 (selection_data_to_lisp_data): Assume incoming selection data are
10490 signed integers, not unsigned. This is to be consistent with
10491 outgoing selection data, which was modified to use signed integers
10492 in as part of the fix to Bug#9196 in response to Jan D.'s comment
10493 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
10494 expects long, not unsigned long.
10496 2011-09-14 Eli Zaretskii <eliz@gnu.org>
10498 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
10499 computation of loop end. Reported by Johan Bockgård
10502 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
10504 * frame.c (Fother_visible_frames_p): Function deleted.
10506 2011-09-12 Eli Zaretskii <eliz@gnu.org>
10508 * indent.c (compute_motion): Process display vector front to back
10509 rather than the other way around. (Bug#2496)
10511 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
10513 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
10515 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
10517 * minibuf.c (Fread_from_minibuffer): Doc fix.
10519 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10521 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
10522 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
10524 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
10526 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
10527 value for non-existent files.
10529 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10531 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10532 set its "size" to -1. This will set the modtime_size field of
10533 the corresponding buffer to -1, which is what
10534 verify-visited-file-modtime expects for files that do not exist.
10537 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
10539 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10541 * lisp.h: ... from here. push_key_description is no longer
10542 defined in keyboard.c, so its declaration should not be in
10543 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10544 logically belongs with push_key_description.
10546 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10548 * buffer.h: Include <sys/types.h> instead of <time.h>.
10549 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
10550 Problem reported by Herbert J. Skuhra.
10552 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
10554 * xml.c (parse_region): Make the parsing work for
10555 non-comment-starting XML files again (bug#9144).
10557 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
10559 * image.c (gif_load): Fix calculation of bottom and right corner.
10562 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10564 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10565 redisplay in small windows.
10567 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10569 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10571 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10573 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10574 Operate on live windows only.
10576 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10578 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10580 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10582 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10583 only under bidi iteration.
10585 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10587 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10589 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10591 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10592 Without this fix, the command to link temacs failed due to an
10593 undefined symbol __builtin_isnan. This is because
10594 /usr/include/iso/math_c99.h #defines isnan(x) to
10595 __builtin_isnan(x), but the bundled gcc, which identifies itself
10596 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10598 * floatfns.c (isnan): #undef, and then #define to a clone of
10600 (Fisnan): Always define, since it's always available now.
10601 (syms_of_floatfns): Always define isnan at the Lisp level.
10603 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10605 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10607 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10609 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10610 The previous code assumed that file offsets (off_t values) fit in
10611 EMACS_INT variables, which is not true on typical 32-bit hosts.
10612 The code messed up by falsely reporting buffer overflow in cases
10613 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10614 when "big" contains more than 2**29 bytes, even though this
10615 inserts just one byte and does not overflow the buffer.
10616 (Finsert_file_contents): Store file offsets as off_t
10617 values, not as EMACS_INT values. Check for overflow when
10618 converting between EMACS_INT and off_t. When checking for
10619 buffer overflow or for overlap, take the offsets into account.
10620 Don't use EMACS_INT for small values where int suffices.
10621 When checking for overlap, fix a typo: ZV was used where
10622 ZV_BYTE was intended.
10623 (Fwrite_region): Don't assume off_t fits into 'long'.
10624 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10626 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10628 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10630 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10632 sprintf-related integer and memory overflow issues (Bug#9412).
10634 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10635 (esprintf, exprintf, evxprintf): New functions.
10636 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10637 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10638 (modify_event_symbol): Do not assume that the length of
10639 name_alist_or_stem is safe to alloca and fits in int.
10640 (Fexecute_extended_command): Likewise for function name and binding.
10641 (Frecursion_depth): Wrap around reliably on integer overflow.
10642 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10643 since some callers pass EMACS_INT values.
10644 (Fsingle_key_description): Don't crash if symbol name contains more
10645 than MAX_ALLOCA bytes.
10646 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10647 (get_minibuffer): Arg is now EMACS_INT, not int.
10648 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10649 (esprintf, exprintf, evxprintf): New decls.
10650 * window.h (command_loop_level, minibuf_level): Reflect API changes.
10652 * dbusbind.c (signature_cat): New function.
10653 (xd_signature, Fdbus_register_signal):
10654 Do not overrun buffer; instead, report string overflow.
10656 * dispnew.c (add_window_display_history): Don't overrun buffer.
10657 Truncate instead; this is OK since it's just a log.
10659 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10660 even if the time zone offset is outlandishly large.
10661 Don't mishandle offset == INT_MIN.
10663 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10664 when creating daemon; the previous buffer-overflow check was incorrect.
10666 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10667 which has the guts of the old verror function.
10669 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10670 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10672 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10673 (font_unparse_xlfd): Don't blindly alloca long strings.
10674 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10675 fits in int, when using sprintf. Use single snprintf to count
10676 length of string rather than counting it via multiple sprintfs;
10677 that's simpler and more reliable.
10678 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10679 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10680 sprintf, in case result does not fit in int.
10682 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10683 (fontset_from_font): Print it.
10685 * frame.c (tty_frame_count): Now printmax_t, not int.
10686 (make_terminal_frame, set_term_frame_name): Print it.
10687 (x_report_frame_params): In X, window IDs are unsigned long,
10688 not signed long, so print them as unsigned.
10689 (validate_x_resource_name): Check for implausibly long names,
10690 and don't assume name length fits in 'int'.
10691 (x_get_resource_string): Don't blindly alloca invocation name;
10692 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10695 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10696 (xg_check_special_colors, xg_set_geometry):
10697 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10699 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10700 Use esprintf, not sprintf, in case result does not fit in int.
10702 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10703 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10704 it as a large positive number.
10705 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10706 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10708 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10709 in case result does not fit in int.
10711 * print.c (float_to_string): Detect width overflow more reliably.
10712 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10713 buffer overrun. Don't assume list length fits in 'int'. Treat
10714 print length of 0 as 0, not as infinity; to be consistent with other
10715 uses of print length in this function. Don't overflow print length
10716 index. Don't assume hash table size fits in 'long', or that
10717 vectorlike size fits in 'unsigned long'.
10719 * process.c (make_process): Use printmax_t, not int, to format
10720 process-name gensyms.
10722 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10724 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10725 to avoid potential buffer overrun.
10727 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10728 if X resource line is longer than 512 bytes.
10730 * xfns.c (x_window): Make sprintf buffer a bit bigger
10731 to avoid potential buffer overrun.
10733 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10735 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10737 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10739 Integer overflow fixes for scrolling, etc.
10740 Without these, Emacs silently mishandles large integers sometimes.
10741 For example, "C-u 4294967297 M-x recenter" was treated as if
10742 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10744 * xdisp.c (try_window_id): Check Emacs fixnum range before
10745 converting to 'int'.
10747 * window.c (window_scroll_line_based, Frecenter):
10748 Check that an Emacs fixnum is in range before assigning it to 'int'.
10749 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10750 values converted from Emacs fixnums.
10751 (Frecenter): Don't wrap around a line count if it is out of 'int'
10752 range; instead, treat it as an extreme value.
10753 (Fset_window_configuration, compare_window_configurations):
10754 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10756 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10757 that can exceed INT_MAX. Check that EMACS_INT value is in range
10758 before assigning it to the (possibly-narrower) index.
10759 (match_limit): Don't assume that a fixnum can fit in 'int'.
10761 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10764 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10765 (Fvertical_motion): Don't wrap around LINES values that don't fit
10766 in 'int'. Instead, treat them as extreme values. This is good
10767 enough for windows, which can't have more than INT_MAX lines anyway.
10769 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10771 * Require libxml/parser.h to avoid compilation warning.
10773 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10775 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10776 since this reportedly can destroy thread storage.
10778 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10780 * syntax.c (find_defun_start): Update all cache variables if
10781 exiting early (Bug#9401).
10783 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10785 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10787 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10788 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10789 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10791 * term.c (tty_append_glyph): New function.
10792 (produce_stretch_glyph): Static function and its prototype deleted.
10794 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10797 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10799 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10800 when checking :margin (Bug#9390).
10801 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10802 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10803 so that the name doesn't mislead. All uses changed.
10805 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10807 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after

10814 (move_it_vertically_backward): When DY == 0, make sure we get to
10815 the first character in the line after the newline.
10817 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10819 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10820 (ccl_driver): Do not generate an out-of-range pointer.
10821 (Fccl_execute_on_string): Remove unnecessary check for
10822 integer overflow, noted by Stefan Monnier in
10823 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10824 Remove a FIXME that didn't need fixing.
10825 Simplify the newly-introduced buffer reallocation code.
10827 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10829 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10831 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10833 Integer and memory overflow issues (Bug#9196).
10835 * doc.c (get_doc_string): Rework so that
10836 get_doc_string_buffer_size is the actual buffer size, rather than
10837 being 1 less than the actual buffer size; this makes xpalloc more
10840 * image.c (x_allocate_bitmap_record, cache_image):
10841 * xselect.c (Fx_register_dnd_atom):
10842 Simplify previous changes by using xpalloc.
10844 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10845 since either will do and ptrdiff_t is convenient with xpalloc.
10847 * charset.c (charset_table_size)
10848 (struct charset_sort_data.priority): Now ptrdiff_t.
10849 (charset_compare): Don't overflow if priorities differ greatly.
10850 (Fsort_charsets): Don't assume list length fits in int.
10851 Check for size-calculation overflow when allocating sort data.
10852 (syms_of_charset): Allocate an initial charset table that is
10853 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10855 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10857 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10858 The actual value is always <= INT_MAX, and leaving it unsigned made
10859 overflow checking harder.
10861 * dispextern.h (struct glyph_matrix.rows_allocated)
10862 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10863 with xpalloc. The values are still always <= INT_MAX.
10865 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10867 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10868 (SAFE_NALLOCA): New macro.
10870 * region-cache.c (struct boundary.pos, find_cache_boundary)
10871 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10872 (set_cache_region, invalidate_region_cache)
10873 (revalidate_region_cache, know_region_cache, region_cache_forward)
10874 (region_cache_backward, pp_cache):
10875 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10876 so that ptrdiff_t * can be passed to xpalloc.
10877 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
10878 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
10879 (pp_cache): Don't assume cache_len fits in int.
10880 * region-cache.h: Adjust extern decls to match.
10882 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
10883 EMACS_INT, since either will do, for xpalloc.
10885 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
10886 (xnmalloc, xnrealloc, xpalloc): New functions.
10888 * bidi.c (bidi_shelve_header_size): New constant.
10889 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
10890 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
10892 * bidi.c (bidi_cache_shrink):
10893 * buffer.c (overlays_at, overlays_in, record_overlay_string)
10895 Don't update size of array until after memory allocation succeeds,
10896 because xmalloc/xrealloc may not return.
10897 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10898 now that we have proper integer overflow checking.
10899 (record_overlay_string, overlay_strings): Catch overflows when
10900 calculating size of overlay_str_buf.
10902 * callproc.c (Fcall_process): Check for size overflow when
10903 calculating size of args2.
10904 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
10905 Normally we prefer signed values, but sticking with ptrdiff_t would
10906 require adding more-complicated checks.
10908 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10909 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
10910 Redo buffer-overflow calculations to avoid integer overflow.
10911 Add a FIXME comment where memory seems to be over-allocated.
10913 * character.c (Fstring): Check for size-calculation overflow.
10915 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
10916 unnecessary integer overflow. Check for size overflow.
10917 (encode_coding_object): Don't update size until xmalloc succeeds.
10919 * composite.c (get_composition_id): Check for overflow in glyph
10920 length calculations.
10922 Integer and memory overflow fixes for display code.
10923 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
10924 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
10925 (scrolling_window): Check for overflow in size calculations.

10937 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
10938 (get_doc_string): Check for size calculation overflow.
10939 Don't update size until allocation succeeds.
10940 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
10941 EMACS_INT, where ptrdiff_t will do.
10942 (Fsubstitute_command_keys): Check for string overflow.
10944 * editfns.c (set_time_zone_rule): Don't assume environment length
10946 (message_length): Now ptrdiff_t, not int.
10947 (Fmessage_box): Don't update size until allocation succeeds.
10948 Don't assume message length fits in int.
10949 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10951 * emacs.c (main): Do not reallocate argv, since there is a null at
10952 the end that can be overwritten, and this way there's no need to
10953 worry about size-calculation overflow.
10954 (sort_args): Check for size-calculation overflow.
10956 * eval.c (init_eval_once, grow_specpdl): Don't update size until
10958 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
10960 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
10961 (x_set_scroll_bar_width, x_figure_window_size):
10962 Check for integer overflow.
10963 (x_set_alpha): Do not assume XINT fits in int.
10965 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10966 This is for the members text_lines, text_cols, total_lines, total_cols,
10967 where the system imposes an 'int' limit.
10969 * fringe.c (Fdefine_fringe_bitmap):
10970 Don't update size until alloc works.
10972 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
10973 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
10975 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
10976 Check for size-calculation overflow.
10977 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10978 do, as we prefer signed integers.
10979 (id_to_widget.max_size, id_to_widget.used)
10980 (xg_store_widget_in_map, xg_remove_widget_from_map)
10981 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
10982 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
10983 Use and return ptrdiff_t, not int.
10984 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
10985 * gtkutil.h: Change prototypes to match the above.
10987 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
10988 are duplicate now that they've been promoted to lisp.h.
10989 (x_allocate_bitmap_record, x_alloc_image_color)
10990 (make_image_cache, cache_image, xpm_load):
10991 Don't update size until alloc is done.

11002 Use ptrdiff_t, not int, to count maps.
11003 (read_char_minibuf_menu_prompt): Check for overflow in size
11004 calculations. Don't update size until allocation succeeds.
11005 Redo calculations to avoid overflow.
11006 * keyboard.h: Change prototypes to match the above.
11008 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,

11034 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
11035 for command line length. Do not attempt to address one before the
11036 beginning of an array, as that's not portable.
11038 * term.c (max_frame_lines): Remove; unused.
11039 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
11041 (encode_terminal_code, calculate_costs): Check for size

11064 Use ptrdiff_t, not int, for sizes.
11065 (Finternal_make_lisp_face, cache_face):
11066 Check for size calculation overflow.
11067 (cache_face): Treat size calculation overflows as if they were
11068 memory exhaustion (the usual treatment), rather than aborting.
11070 * xfns.c (x_encode_text, x_set_name_internal)
11071 (Fx_change_window_property): Use ptrdiff_t, not int, to count
11072 sizes, since they can exceed INT_MAX in size. Check for size

11076 (xg_select): Check for size calculation overflow.
11077 Don't update size until alloc done.
11079 * xrdb.c (get_environ_db): Don't assume path length fits in int,
11080 as sprintf is limited to int lengths.
11082 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
11083 (X_LONG_MIN): New macros.
11084 Use them to make the following changes clearer.
11085 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
11086 This change doesn't affect the value now, but it may help remind
11087 future maintainers not to raise the value too much later.
11088 (SELECTION_QUANTUM): Remove, replacing with ...
11089 (selection_quantum): ... new function, which avoids overflow.
11091 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
11092 assumption that selection length fits in 'int'.

11105 (lisp_data_to_selection_data, x_property_data_to_lisp):

11109 Don't store size until memory allocation succeeds.
11110 (x_get_window_property): Plug memory leak on memory exhaustion.
11111 Don't double-block input; malloc is safe here. Don't assume 2**34
11112 - 4 fits in unsigned long. Add an xassert to check
11113 XGetWindowProperty overflow. Be more careful about overflow
11114 calculations, and distinguish size from memory overflow better.
11115 (receive_incremental_selection): When tracing, don't assume
11116 unsigned int is less than INT_MAX.
11117 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
11118 harmful) conversions of unsigned short to int.
11119 (lisp_data_to_selection_data): Don't assume that integers
11120 in the range -65535 through -1 fit in an X unsigned short.
11121 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
11122 result parameters unless successful. Rely on cons_to_unsigned
11123 to report problems with elements; the old code wasn't right anyway.
11124 (x_check_property_data): Check for int overflow; we cannot use
11125 a wider type due to X limits.
11126 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

11157 * image.c (xpm_get_color_table_h):
11158 * lisp.h (hash_lookup, hash_put):
11159 * minibuf.c (Ftest_completion):
11160 Use ptrdiff_t for hash table indexes, not int (which is too
11161 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
11162 32-bit --with-wide-int hosts).
11164 * charset.c (Fdefine_charset_internal): Check for integer overflow.
11165 Add a FIXME comment about memory leaks.
11166 (syms_of_charset): Don't assume xmalloc returns.
11168 Don't assume that stated character widths fit in int.

11170 * character.h (CHAR_WIDTH):
11171 * indent.c (MULTIBYTE_BYTES_WIDTH):
11172 Use sanitize_char_width to avoid undefined and/or bad behavior
11173 with outlandish widths.
11174 * character.h (sanitize_tab_width): Rename from sanitize_width,
11175 now that we have two such functions. All uses changed.
11176 (sanitize_char_width): New inline function.
11178 Don't assume that tab-width fits in int.
11179 * character.h (sanitize_width): New inline function.

11186 * fileio.c: Integer overflow issues with file modes.
11187 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
11189 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

11196 exceed limits imposed by XClientMessageEvent, as well as the usual
11197 ptrdiff_t and size_t limits.
11199 * keyboard.c: Overflow, signedness and related fixes.
11200 (make_lispy_movement): Use same integer type in forward decl
11201 that is used in the definition.
11202 (read_key_sequence, keyremap_step):
11203 Change bufsize argument back to int, undoing my 2011-03-30 change.
11204 We prefer signed types, and int is wide enough here.
11205 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
11206 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
11207 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
11208 length, not size_t. Use ptrdiff_t for index, not int.
11209 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
11210 possibility of integer overflow.
11212 Overflow, signedness and related fixes for images.
11214 * dispextern.h (struct it.stack[0].u.image.image_id)
11215 (struct_it.image_id, struct image.id, struct image_cache.size)
11216 (struct image_cache.used, struct image_cache.ref_count):
11217 * gtkutil.c (update_frame_tool_bar):
11218 * image.c (x_reference_bitmap, Fimage_size, Fimage_mask_p)
11219 (Fimage_metadata, free_image_cache, clear_image_cache, lookup_image)
11220 (cache_image, mark_image_cache, x_kill_gs_process, Flookup_image):
11221 * nsmenu.m (update_frame_tool_bar):
11222 * xdisp.c (calc_pixel_width_or_height):
11223 * xfns.c (image_cache_refcount):
11224 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
11225 on typical 64-bit hosts.
11227 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
11228 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

11231 when the callers expect that.
11232 (image_ascent): Redo ascent calculation to avoid int overflow.
11233 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
11234 (lookup_image): Remove unnecessary tests.
11235 (xbm_image_p): Locals are now of int, not EMACS_INT,
11236 since parse_image_check makes sure they fit into int.
11237 (png_load, gif_load, svg_load_image):
11238 Prefer int to unsigned where either will do.
11239 (tiff_handler): New function, combining the cores of the
11240 old tiff_error_handler and tiff_warning_handler.
11241 This function is rewritten to use vsnprintf and thereby avoid
11242 stack buffer overflows. It uses only the features of vsnprintf
11243 that are common to both POSIX and native Microsoft.
11244 (tiff_error_handler, tiff_warning_handler): Use it.
11245 (tiff_load, gif_load, imagemagick_load_image):
11246 Don't assume :index value fits in 'int'.

11248 (imagemagick_load_image): Check that crop parameters fit into
11249 the integer types that MagickCropImage accepts. Don't assume
11250 Vimagemagick_render_type has a nonnegative value. Don't assume
11251 size_t fits in 'long'.
11252 (gs_load): Use printmax_t to print the widest integers possible.
11253 Check for integer overflow when computing image height and width.
11255 2011-08-26 Eli Zaretskii <eliz@gnu.org>
11257 * xdisp.c (redisplay_window): Don't force window start if point

11266 (handle_single_display_spec): If the display spec is of the form
11267 `(space ...)', and specifies display in the text area, return 2
11269 (try_cursor_movement): Check for the need to scroll more
11270 accurately, and prefer exact match for point under bidi.
11271 Don't advance `row' beyond the last row of the window.
11273 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
11274 into disp_prop; all users changed.
11276 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

11288 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
11289 buffers, return left-to-right.
11290 (set_cursor_from_row): Consider candidate row a win if its glyph
11291 represents a newline and point is on that newline. Fixes cursor
11292 positioning on the newline at EOL of R2L text within L2R
11293 paragraph, and vice versa.
11294 (try_cursor_movement): Check continued rows, in addition to
11295 continuation rows. Fixes unwarranted scroll when point enters a
11296 continued line of R2L text within an L2R paragraph, or vice versa.
11297 (cursor_row_p): Consider the case of point being equal to
11298 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
11299 from the end of a short line to the beginning of a continued line
11300 of R2L text within L2R paragraph.
11301 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

11317 2011-08-22 Kenichi Handa <handa@m17n.org>
11319 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
11320 extra slot even if the purpose is char-code-property-table.
11322 2011-08-23 Eli Zaretskii <eliz@gnu.org>
11324 * xdisp.c (redisplay_window): When computing centering_position,
11325 account for the height of the header line. (Bug#8874)
11327 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
11328 instead of CHAR_TO_BYTE. Fixes a crash when a completion
11329 candidate is selected by the mouse, and that candidate has a
11330 composed character under the mouse.
11332 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
11333 coordinates reported by pos-visible-in-window-p for a composed
11334 character in column zero.
11336 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

11342 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
11343 consider it a hit if to_charpos is anywhere in the range of the
11344 composed buffer positions.
11346 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
11348 * image.c (gif_load): Don't assume that each subimage has the same
11349 dimensions as the base image. Handle disposal method that is
11350 "undefined" by the gif spec (Bug#9335).
11352 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
11354 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

11357 2011-08-19 Eli Zaretskii <eliz@gnu.org>
11359 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
11360 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
11361 from an Org mode buffer to a Speedbar frame.
11363 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
11364 a composition, take its buffer position from IT->cmp_it.charpos.
11365 Fixes cursor positioning at the beginning of a line that begins
11366 with a composed character.
11368 2011-08-18 Eli Zaretskii <eliz@gnu.org>
11370 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
11371 character bidirectional type, use STRONG_L instead. Fixes crashes
11372 in a buffer produced by `describe-categories'.
11374 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
11375 members before the level stack, so they would be saved and
11376 restored when copying iterator state. Fixes incorrect reordering
11377 around TABs covered by display properties.

11511 entry. Force push_it to save on the stack the current
11512 buffer/string position, to be restored by pop_it. Fix flags in
11513 the iterator structure wrt the object coming from a display
11514 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
11515 properties. (Bug#9284)

11677 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11679 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
11680 This is needed if max-image-size is a floating-point number.
11682 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11684 * print.c (print_object): Print empty symbol as ##.
11686 * lread.c (read1): Read ## as empty symbol.
11688 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11690 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
11691 setting frame foreground color (Bug#9175).
11692 (x_set_background_color): Likewise.
11694 * nsmenu.m (-setText): Size tooltip dimensions precisely to
11695 contents (Bug#9176).
11696 (EmacsTooltip -init): Remove bezels and add shadows to
11699 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
11700 or scroll bar (Bug#8470).
11702 * nsfont.m (nsfont_open): Remove assignment to voffset and
11703 unnecessary vars hshink, expand, hd, full_height, min_height.
11704 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
11706 * nsterm.h (nsfont_info): Remove voffset field.
11708 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11710 Implement strike-through and overline on NextStep (Bug#8863).
11712 * nsfont.m (nsfont_open): Use underline position provided by font,
11713 instead of hard-coded value of 2.
11714 (nsfont_draw): Call ns_draw_text_decoration instead.
11716 * nsterm.h: Add declaration for ns_draw_text_decoration.
11718 * nsterm.m (ns_draw_text_decoration): New function for drawing
11719 underline, overline, and strike-through.
11720 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
11721 ns_draw_text_decoration. Change treatment of cursor drawing to
11722 accommodate underlining, etc.
11724 2011-07-28 Eli Zaretskii <eliz@gnu.org>
11726 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
11729 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11731 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11732 Without this fix, if a signal arrives just after memory fills up,
11733 'malloc' might be invoked reentrantly.
11735 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11736 In other words, assume that every image size is allowed, on non-X
11737 hosts. This assumption is probably wrong, but it lets Emacs compile.
11739 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11741 * regex.c (re_iswctype): Convert return values to boolean.
11743 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
11745 * xdisp.c (compute_display_string_pos): Don't use cached display
11746 string position if the buffer had its restriction changed.
11749 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11751 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11753 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11755 Integer signedness and overflow and related fixes. (Bug#9079)
11757 * bidi.c: Integer size and overflow fixes.
11758 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
11759 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
11760 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11761 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11762 (bidi_find_other_level_edge):
11763 Use ptrdiff_t instead of EMACS_INT where either will do.
11764 This works better on 32-bit hosts configured --with-wide-int.
11765 (bidi_cache_ensure_space): Check for size-calculation overflow.
11766 Use % rather than repeated addition, for better worst-case speed.
11767 Don't set bidi_cache_size until after xrealloc returns, because it
11769 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11770 (bidi_cache_ensure_space): Also check that the bidi cache size
11771 does not exceed that of the largest Lisp string or buffer. See Eli
11772 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11774 * alloc.c (__malloc_size_t): Remove.
11775 All uses replaced by size_t. See Andreas Schwab's note
11776 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11778 * image.c: Improve checking for integer overflow.
11779 (check_image_size): Assume that f is nonnull, since
11780 it is always nonnull in practice. This is one less thing to
11781 worry about when checking for integer overflow later.
11782 (x_check_image_size): New function, which checks for integer
11783 overflow issues inside X.
11784 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11785 This removes the need for a memory_full check.
11786 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11787 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11788 (xbm_read_bitmap_data): Change locals back to 'int', since
11789 their values must fit in 'int'.
11790 (xpm_load_image, png_load, tiff_load):
11791 Invoke x_create_x_image_and_pixmap earlier,
11792 to avoid much needless work if the image is too large.
11793 (tiff_load): Treat overly large images as if
11794 x_create_x_image_and_pixmap failed, not as malloc failures.
11795 (gs_load): Use x_check_image_size.
11797 * gtkutil.c: Omit integer casts.
11798 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11799 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11801 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11803 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11804 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11805 would wrongly return t on a 64-bit host.
11807 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11808 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11809 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11810 and therefore cause GCC to emit a bogus diagnostic in some cases.
11812 * image.c: Integer signedness and overflow and related fixes.
11813 This is not an exhaustive set of fixes, but it's time to
11814 record what I've got.
11815 (lookup_pixel_color, check_image_size): Remove redundant decls.
11816 (check_image_size): Don't assume that arbitrary EMACS_INT values
11817 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11818 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11819 (tiff_load, imagemagick_load_image):
11820 Check for overflow in size calculations.
11821 (x_create_x_image_and_pixmap): Remove unnecessary test for
11822 xmalloc returning NULL; that can't happen.
11823 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11824 (xpm_color_bucket): Use better integer hashing function.
11825 (xpm_cache_color): Don't possibly over-allocate memory.
11826 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11827 (gif_memory_source):
11828 Use ptrdiff_t, not int or size_t, to record sizes.
11829 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11830 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11831 either works, as we prefer signed integers.
11832 (tiff_read_from_memory, tiff_write_from_memory):
11833 Return tsize_t, not size_t, since that's what the TIFF API wants.
11834 (tiff_read_from_memory): Don't fail simply because the read would
11835 go past EOF; instead, return a short read.
11836 (tiff_load): Omit no-longer-needed casts.
11837 (Fimagemagick_types): Don't assume size fits into 'int'.
11839 Improve hashing quality when configured --with-wide-int.
11840 * fns.c (hash_string): New function, taken from sxhash_string.
11841 Do not discard information about ASCII character case; this
11842 discarding is no longer needed.
11843 (sxhash-string): Use it. Change sig to match it. Caller changed.
11844 * lisp.h: Declare it.
11845 * lread.c (hash_string): Remove, since we now use fns.c's version.
11846 The fns.c version returns a wider integer if --with-wide-int is
11847 specified, so this should help the quality of the hashing a bit.
11849 * emacs.c: Integer overflow minor fix.
11850 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11851 Define only if GNU_LINUX.
11852 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11854 * dispnew.c: Integer signedness and overflow fixes.
11855 Remove unnecessary forward decls, that were a maintenance hassle.
11856 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11858 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11859 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11860 (prepare_desired_row, line_draw_cost):
11861 Use int, not unsigned, where either works.
11862 (save_current_matrix, restore_current_matrix):
11863 Use ptrdiff_t, not size_t, where either works.
11864 (init_display): Check for overflow more accurately, and without
11865 relying on undefined behavior.
11867 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11868 Remove, replacing with the new symbols in lisp.h. All uses changed.
11869 * fileio.c (make_temp_name):
11870 * filelock.c (lock_file_1, lock_file):
11871 * xdisp.c (message_dolog):
11872 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11873 Use pMd etc. instead.
11874 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11875 replacing the pWIDE etc. symbols removed from editfns.c.
11877 * keyboard.h (num_input_events): Now uintmax_t.
11878 This is (very slightly) less likely to mess up due to wraparound.
11881 * buffer.c: Integer signedness fixes.
11882 (alloc_buffer_text, enlarge_buffer_text):
11883 Use ptrdiff_t rather than size_t when either will do, as we prefer
11886 * alloc.c: Integer signedness and overflow fixes.
11887 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11888 (__malloc_size_t): Default to size_t, not to int.
11889 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11890 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11891 Prefer ptrdiff_t to size_t when either would do, as we prefer
11893 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11894 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11895 Now const. Initialize with values that are in range even if char
11897 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11898 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11899 These functions do the right thing with sizes > 2**32.
11900 (check_depth): Now ptrdiff_t, not int.
11901 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11902 Adjust to new way of storing sizes. Check for size overflow bugs
11904 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11905 slightly wrong anyway, as it missed one instance of
11906 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11907 (refill_memory_reserve): Omit needless cast to size_t.
11908 (mark_object_loop_halt): Mark as externally visible.
11910 * xselect.c: Integer signedness and overflow fixes.
11911 (Fx_register_dnd_atom, x_handle_dnd_message):
11912 Use ptrdiff_t, not size_t, since we prefer signed.
11913 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11914 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11915 x_dnd_atoms_size and x_dnd_atoms_length.
11917 * doprnt.c: Prefer signed to unsigned when either works.
11919 * doprnt.c (doprnt):
11921 * xdisp.c (vmessage):
11922 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11923 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11924 prefer signed arithmetic to avoid comparison confusion.
11925 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11926 but is a bit tricky.
11928 Assume freestanding C89 headers, string.h, stdlib.h.
11929 * data.c, doprnt.c, floatfns.c, print.c:
11930 Include float.h unconditionally.
11931 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11932 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11933 * regex.c: Likewise for stddef.h, string.h.
11934 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11935 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11936 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11937 (STDC_HEADERS): Remove obsolete defines.
11938 * sysdep.c: Include limits.h unconditionally.
11940 Assume support for memcmp, memcpy, memmove, memset.
11941 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11942 * regex.c (memcmp, memcpy):
11943 Remove; we assume C89 now.
11945 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11946 (__malloc_safe_bcopy): Remove; no longer needed.
11948 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11949 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11950 well either way, and we prefer signed to unsigned.
11952 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11954 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11955 closes the connection while we're reading (bug#9182).
11957 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11959 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11960 are specified (Bug#9168).
11962 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11964 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11965 Found by GCC static checking and --with-wide-int on a 32-bit host.
11967 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11969 * xdisp.c (compute_display_string_pos): Fix logic of caching
11970 previous display string position. Initialize cached_prev_pos to
11971 -1. Fixes slow-down at the beginning of a buffer.
11973 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11975 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11976 for attrs[LFACE_FONTSET_INDEX].
11978 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11980 * xml.c (parse_region): Remove unused local
11981 that was recently introduced.
11983 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11985 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11986 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11988 * xdisp.c (move_it_in_display_line_to): Record the best matching
11989 position for TO_CHARPOS while scanning the line, and restore it on
11990 exit if none of the characters scanned was an exact match.
11991 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11992 when exact match is impossible due to invisible text, and the
11993 lines are truncated.
11995 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11997 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
12000 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12002 Fix a significant slow-down of cursor motion with C-n, C-p,
12003 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
12004 auto-repeat under bidi redisplay in fontified buffers.
12005 * xdisp.c (compute_stop_pos_backwards): New function.
12006 (next_element_from_buffer): Call compute_stop_pos_backwards to
12007 find a suitable prev_stop when we find ourselves before
12009 (reseat): Don't look for prev_stop, as that could mean a very long
12011 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
12012 <cached_disp_overlay_modiff>: Cache for last found display string
12014 (compute_display_string_pos): Return the cached position if asked
12015 about the same buffer in the same area of character positions, and
12016 the buffer wasn't changed since the time the display string
12017 position was cached.
12019 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12021 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
12022 is an integer, which is important for empty lines. (Bug#9149)
12024 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
12026 * frame.c (Fmodify_frame_parameters): In tty case, update the
12027 default face if necessary (Bug#4238).
12029 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
12031 * editfns.c (Fstring_to_char): No need to explain what a character
12032 is in the docstring (Bug#6576).
12034 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12036 * xml.c (parse_region): Make sure we always return a tree.
12038 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
12040 * xml.c (parse_region): If a document contains only comments,
12043 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12045 * xml.c (make_dom): Return comments, too.
12047 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
12050 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
12051 and the surrounding thread.
12052 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
12053 rather than fgets, and retry after EINTR. Otherwise, 'emacs
12054 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
12056 * s/openbsd.h (BROKEN_SIGIO): Define.
12057 * unexelf.c (unexec) [__OpenBSD__]:
12058 Don't update the .mdebug section of the Alpha COFF symbol table.
12060 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12062 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
12065 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
12067 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
12068 This fixes some race conditions on the permissions of any newly
12071 * alloc.c (valid_pointer_p): Use pipe, not open.
12072 This fixes some permissions issues when debugging.
12074 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
12075 If fchown fails to set both uid and gid, try to set just gid,
12076 as that is sometimes allowed. Adjust the file's mode to eliminate
12077 setuid or setgid bits that are inappropriate if fchown fails.
12079 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
12081 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
12082 to compare Lisp_Objects.
12083 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
12084 global_gnutls_log_level, don't mistake it for a Lisp_Object.
12085 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
12087 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
12089 * lread.c (read_integer): Unread even EOF character.
12090 (read1): Likewise. Properly record start position of symbol.
12092 * lread.c (read1): Read `#:' as empty uninterned symbol if no
12093 symbol character follows.
12095 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
12097 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
12098 This works around a problem with the previous change to Fcopy_file.
12099 Recent glibc declares fchown with __attribute__((warn_unused_result)),
12100 and without this change, GCC might complain about discarding
12101 fchown's return value.
12103 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
12105 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
12107 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
12109 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
12111 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
12113 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
12114 it's used from the C level.
12116 * process.c: Use the same condition for POLL_FOR_INPUT in both
12117 keyboard.c and process.c (bug#1858).
12119 2011-07-09 Lawrence Mitchell <wence@gmx.li>

12199 the iterator is before prev_stop.
12200 (init_iterator): Initialize bidi_p from the default value of

12681 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

12718 Random fixes. E.g., (random) never returned negative values.
12719 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
12720 subseconds part to the entropy, as that's a bit more random.
12721 Prefer signed to unsigned, since the signedness doesn't matter and
12722 in general we prefer signed. When given a limit, use a
12723 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12724 latter isn't right if USE_2_TAGS_FOR_INTS.
12725 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12726 not 0..VALMASK. Don't discard "excess" bits that random () returns.

12750 error be more correct.
12752 * fns.c (Frequire): Remove the mention of the .gz files, since

12769 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
12770 Also (re)move comments that are misplaced or no longer relevant.

12871 * eval.c (struct backtrace): Simplify and port the data structure.
12872 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12873 signed bit field, as this assumption is not portable and it makes
12874 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12875 "char debug_on_exit : 1" as this is not portable either; instead,
12876 use the portable "unsigned int debug_on_exit : 1". Remove unused
12877 member evalargs. Remove obsolete comments about cc bombing out.

13041 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
13043 Integer and buffer overflow fixes (Bug#8873).
13045 * print.c (printchar, strout): Check for string overflow.
13046 (PRINTPREPARE, printchar, strout):
13047 Don't set size unless allocation succeeds.
13049 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
13050 for sizes. Check for string overflow more accurately.
13051 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
13053 * macros.c: Integer and buffer overflow fixes.
13054 * keyboard.h (struct keyboard.kbd_macro_bufsize):
13055 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
13056 Use ptrdiff_t, not int, for sizes.
13057 Don't increment bufsize until after realloc succeeds.
13058 Check for size-calculation overflow.
13059 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
13061 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
13063 * lread.c: Integer overflow fixes.
13064 (read_integer): Radix is now EMACS_INT, not int,
13065 to improve quality of diagnostics for out-of-range radices.
13066 Calculate buffer size correctly for out-of-range radices.
13067 (read1): Check for integer overflow in radices, and in
13068 read-circle numbers.
13069 (read_escape): Avoid int overflow.
13070 (Fload, openp, read_buffer_size, read1)
13071 (substitute_object_recurse, read_vector, read_list, map_obarray):
13072 Use ptrdiff_t, not int, for sizes.
13073 (read1): Use EMACS_INT, not int, for sizes.
13074 Check for size overflow.
13076 * image.c (cache_image): Check for size arithmetic overflow.
13078 * lread.c: Integer overflow issues.
13079 (saved_doc_string_size, saved_doc_string_length)
13080 (prev_saved_doc_string_size, prev_saved_doc_string_length):
13081 Now ptrdiff_t, not int.

13083 out-of-range doc string lengths.
13084 (read_list): Don't assume file position fits in int.
13085 (read_escape): Check for hex character overflow.
13087 2011-06-22 Leo Liu <sdl.web@gmail.com>
13089 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
13090 Move to minibuffer.el.
13092 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13094 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
13095 The following patches are for when GLYPH_DEBUG && !XASSERT.
13096 * dispextern.h (trace_redisplay_p, dump_glyph_string):
13097 * dispnew.c (flush_stdout):
13098 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
13099 Mark as externally visible.
13100 * dispnew.c (check_window_matrix_pointers): Now static.
13101 * dispnew.c (window_to_frame_vpos):
13102 * xfns.c (unwind_create_frame):
13103 * xterm.c (x_check_font): Remove unused local.
13104 * scroll.c (CHECK_BOUNDS):
13105 * xfaces.c (cache_fache): Rename local to avoid shadowing.
13106 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
13107 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
13108 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
13109 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
13111 (debug_method_add): Use va_list and vsprintf rather than relying
13112 on undefined behavior with wrong number of arguments.
13113 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
13114 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
13115 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
13116 since we're not interested in debugging glyphs with old libraries.
13117 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
13118 GCC 4.6.0's static checking.
13120 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13122 Integer overflow and signedness fixes (Bug#8873).

13131 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
13132 (x_create_bitmap_from_xpm_data):
13133 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
13134 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
13136 * xfaces.c (load_pixmap):
13137 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
13138 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
13139 (.bitmaps_last, struct x_output.icon_bitmap):
13140 Use ptrdiff_t, not int, for bitmap indexes.
13141 (x_allocate_bitmap_record): Check for size overflow.
13142 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
13144 Use ptrdiff_t, not int, for overlay counts.
13145 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
13146 * editfns.c (overlays_around, get_pos_property):
13147 * textprop.c (get_char_property_and_overlay):
13148 * xdisp.c (next_overlay_change, note_mouse_highlight):
13149 * xfaces.c (face_at_buffer_position):
13150 * buffer.c (OVERLAY_COUNT_MAX): New macro.
13151 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
13152 (Fnext_overlay_change, Fprevious_overlay_change)
13153 (mouse_face_overlay_overlaps, Foverlays_in):
13154 Use ptrdiff_t, not int, for sizes.
13155 (overlays_at, overlays_in): Check for size-calculation overflow.
13157 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
13159 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
13160 (x_session_initialize): Do not assume string length fits in int.
13162 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
13163 This is unlikely, but can occur if DPI is outlandish.
13165 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
13166 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
13168 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
13169 * xrdb.c (magic_file_p, search_magic_path):
13170 Omit last arg SUFFIX; it was always 0. All callers changed.
13171 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
13173 * xfont.c (xfont_match): Avoid need for strlen.
13175 * xfns.c: Don't assume strlen fits in int.
13176 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
13178 * xdisp.c (message_log_check_duplicate): Return intmax_t,
13179 not unsigned long, as we prefer signed integers. All callers changed.
13180 Detect integer overflow in repeat count.
13181 (message_dolog): Don't assume print length fits in 39 bytes.
13182 (display_mode_element): Don't assume strlen fits in int.
13184 * termcap.c: Don't assume sizes fit in int and never overflow.
13185 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
13186 (gobble_line): Check for size-calculation overflow.
13188 * minibuf.c (Fread_buffer):
13189 * lread.c (intern, intern_c_string):
13190 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
13191 Don't assume string length fits in int.
13193 * keyboard.c (parse_tool_bar_item):
13194 * gtkutil.c (style_changed_cb): Avoid need for strlen.
13196 * font.c: Don't assume string length fits in int.
13197 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
13198 Use ptrdiff_t, not int.
13199 (font_intern_prop): Don't assume string length fits in int.
13200 Don't assume integer property fits in fixnum.
13201 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
13203 * filelock.c: Fix some buffer overrun and integer overflow issues.
13204 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
13205 Reformulate so as not to need the command string.
13206 Invoke gzip -cd rather than gunzip, as it's more portable.
13207 (lock_info_type, lock_file_1, lock_file):
13208 Don't assume pid_t and time_t fit in unsigned long.
13209 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
13210 (current_lock_owner): Prefer signed type for sizes.
13211 Use memcpy, not strncpy, where memcpy is what is really wanted.
13212 Don't assume (via atoi) that time_t and pid_t fit in int.
13213 Check for time_t and/or pid_t out of range, e.g., via a network share.
13214 Don't alloca where an auto var works fine.
13216 * fileio.c: Fix some integer overflow issues.
13217 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
13218 Don't assume string length fits in int.
13219 (directory_file_name): Don't assume string length fits in long.
13220 (make_temp_name): Don't assume pid fits in int, or that its print
13221 length is less than 20.
13223 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
13225 * coding.c (make_subsidiaries): Don't assume string length fits in int.
13227 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
13229 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
13230 We prefer signed integers, even for size calculations.
13232 * emacs.c: Don't assume string length fits in 'int'.
13233 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
13234 (main): Don't invoke strlen when not needed.
13236 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
13237 (XD_DEBUG_MESSAGE): Don't waste a byte.
13239 * callproc.c (getenv_internal_1, getenv_internal)
13240 (Fgetenv_internal):
13241 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
13243 * lread.c (invalid_syntax): Omit length argument.
13244 All uses changed. This doesn't fix a bug, but it simplifies the
13245 code away from its former Hollerith-constant appearance, and it's
13246 one less 'int' to worry about when looking at integer-overflow issues.
13247 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
13249 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
13250 This didn't break anything, but it didn't help either.
13251 It's confusing to put a bogus integer in a place where the actual
13252 value does not matter.
13253 (LIST_END_P): Remove unused macro and its bogus comment.
13254 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
13256 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
13257 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
13259 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
13260 We prefer signed types, and the value cannot exceed the EMACS_INT
13261 range anyway (because otherwise the length would not be representable).
13262 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
13263 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
13264 This avoids a GCC warning when WIDE_EMACS_INT.
13266 * indent.c (sane_tab_width): New function.
13267 (current_column, scan_for_column, Findent_to, position_indentation)
13268 (compute_motion): Use it. This is just for clarity.
13269 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
13271 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
13273 * lisp.h (lint_assume): New macro.
13274 * composite.c (composition_gstring_put_cache):
13275 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
13277 * editfns.c, insdel.c:
13278 Omit unnecessary forward decls, to simplify future changes.
13280 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
13282 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
13284 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
13285 Use much-faster test for byte-length change.
13286 Don't assume string byte-length fits in 'int'.
13287 Check that character arg fits in 'int'.
13288 (mapcar1): Declare byte as byte, for clarity.
13290 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
13292 * fns.c (concat): Catch string overflow earlier.
13293 Do not rely on integer wraparound.
13295 * dispextern.h (struct it.overlay_strings_charpos)
13296 (struct it.selective): Now EMACS_INT, not int.
13297 * xdisp.c (forward_to_next_line_start)
13298 (back_to_previous_visible_line_start)
13299 (reseat_at_next_visible_line_start, next_element_from_buffer):
13300 Don't arbitrarily truncate the value of 'selective' to int.
13302 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
13304 * composite.c: Don't truncate sizes to 'int'.
13305 (composition_gstring_p, composition_reseat_it)
13306 (composition_adjust_point): Use EMACS_INT, not int.
13307 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
13308 not EMACS_UINT, for indexes.
13310 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
13312 * buffer.c: Include <verify.h>.
13313 (struct sortvec.priority, struct sortstr.priority):
13314 Now EMACS_INT, not int.
13315 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
13316 (struct sortstr.size, record_overlay_string)
13317 (struct sortstrlist.size, struct sortlist.used):
13318 Don't truncate size to int.
13319 (record_overlay_string): Check for size-calculation overflow.
13320 (init_buffer_once): Check at compile-time, not run-time.
13322 2011-06-22 Jim Meyering <meyering@redhat.com>
13324 Don't leak an XBM-image-sized buffer
13325 * image.c (xbm_load): Free the image buffer after using it.
13327 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
13330 * composite.c (find_automatic_composition): Omit needless 'return 0;'
13331 that Sun C diagnosed.
13332 * fns.c (secure_hash): Fix pointer signedness issue.
13333 * intervals.c (static_offset_intervals): New function.
13334 (offset_intervals): Use it.
13336 2011-06-21 Leo Liu <sdl.web@gmail.com>
13339 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
13342 * fns.c (secure_hash): Rename from crypto_hash_function and change
13343 the first arg to accept symbols.
13344 (Fsecure_hash): New primitive.
13345 (syms_of_fns): New symbols.
13347 2011-06-20 Deniz Dogan <deniz@dogan.se>
13349 * process.c (Fset_process_buffer): Clarify return value in
13352 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
13354 * dispnew.c (add_window_display_history): Use BVAR.
13356 * xdisp.c (debug_method_add): Use BVAR.
13357 (check_window_end, dump_glyph_matrix, dump_glyph)
13358 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
13360 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
13363 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
13364 check till after the cache is created in init_frame_faces.
13366 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
13368 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
13370 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
13372 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
13373 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
13374 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
13376 Improve buffer-overflow checking (Bug#8873).
13377 * fileio.c (Finsert_file_contents):
13378 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
13379 Remove the old (too-loose) buffer overflow checks.
13380 They weren't needed, since make_gap checks for buffer overflow.
13381 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
13382 The old code merely checked for Emacs fixnum overflow, and relied
13383 on undefined (wraparound) behavior. The new code avoids undefined
13384 behavior, and also checks for ptrdiff_t and/or size_t overflow.
13386 * editfns.c (Finsert_char): Don't dump core with very negative counts.
13387 Tune. Don't use wider integers than needed. Don't use alloca.
13388 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
13390 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
13392 * insdel.c, lisp.h (buffer_overflow): New function.
13393 (insert_from_buffer_1, replace_range, replace_range_2):
13394 * insdel.c (make_gap_larger):
13395 * editfns.c (Finsert_char):
13396 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
13398 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
13400 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
13402 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
13404 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
13405 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
13407 * fileio.c: Don't assume EMACS_INT fits in off_t.
13408 (emacs_lseek): New static function.
13409 (Finsert_file_contents, Fwrite_region): Use it.
13410 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
13412 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
13414 * fns.c: Don't overflow int when computing a list length.
13415 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
13416 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
13417 truncation on 64-bit hosts. Check for QUIT every
13418 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
13419 faster and is responsive enough.
13420 (Flength): Report an error instead of overflowing an integer.
13421 (Fsafe_length): Return a float if the value is not representable
13422 as a fixnum. This shouldn't happen except in contrived situations.
13423 (Fnthcdr, Fsort): Don't assume list length fits in int.
13424 (Fcopy_sequence): Don't assume vector length fits in int.
13426 * alloc.c: Check that resized vectors' lengths fit in fixnums.
13427 (header_size, word_size): New constants.
13428 (allocate_vectorlike): Don't check size overflow here.
13429 (allocate_vector): Check it here instead, since this is the only
13430 caller of allocate_vectorlike that could cause overflow.
13431 Check that the new vector's length is representable as a fixnum.
13433 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
13434 The previous code was bogus. For example, next_almost_prime (32)
13435 returned 39, which is undesirable as it is a multiple of 3; and
13436 next_almost_prime (24) returned 25, which is a multiple of 5 so
13437 why was the code bothering to check for multiples of 7?
13439 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
13441 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
13443 Variadic C functions now count arguments with ptrdiff_t.
13444 This partly undoes my 2011-03-30 change, which replaced int with size_t.
13445 Back then I didn't know that the Emacs coding style prefers signed int.
13446 Also, in the meantime I found a few more instances where arguments
13447 were being counted with int, which may truncate counts on 64-bit
13448 machines, or EMACS_INT, which may be unnecessarily wide.
13449 * lisp.h (struct Lisp_Subr.function.aMANY)
13450 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
13451 Arg counts are now ptrdiff_t, not size_t.
13452 All variadic functions and their callers changed accordingly.
13453 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
13454 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
13455 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
13456 * callint.c (Fcall_interactively): Check arg count for overflow,
13457 to avoid potential buffer overrun. Use signed char, not 'int',
13458 for 'varies' array, so that we needn't bother to check its size
13459 calculation for overflow.
13460 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
13461 * eval.c (apply_lambda):
13462 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
13463 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
13464 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
13466 * callint.c (Fcall_interactively): Don't use index var as event count.
13468 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
13469 * mem-limits.h (SIZE): Remove; no longer used.
13471 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
13473 Remove unnecessary casts.
13474 * xterm.c (x_term_init):
13475 * xfns.c (x_set_border_pixel):
13476 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
13477 These aren't needed now that we assume ANSI C.
13479 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
13480 It's more likely to cause problems (due to unsigned overflow)
13483 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
13485 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
13487 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
13489 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
13491 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
13493 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
13495 GLYPH_CODE_FACE returns EMACS_INT, not int.
13496 * dispextern.h (merge_faces):
13497 * xfaces.c (merge_faces):
13498 * xdisp.c (get_next_display_element, next_element_from_display_vector):
13499 Don't assume EMACS_INT fits in int.
13501 * character.h (CHAR_VALID_P): Remove unused parameter.
13502 * fontset.c, lisp.h, xdisp.c: All uses changed.
13504 * editfns.c (Ftranslate_region_internal): Omit redundant test.
13506 * fns.c (concat): Minor tuning based on overflow analysis.
13507 This doesn't fix any bugs. Use int to hold character, instead
13508 of constantly refetching from Emacs object. Use XFASTINT, not
13509 XINT, for value known to be a character. Don't bother comparing
13510 a single byte to 0400, as it's always less.
13512 * floatfns.c (Fexpt):
13513 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
13515 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
13518 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
13520 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
13521 Without this fix, on a 64-bit host (aset S 0 4294967386) would
13522 incorrectly succeed when S was a string, because 4294967386 was
13523 truncated before it was used.
13525 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13526 Otherwise, an out-of-range integer could cause undefined behavior
13529 * composite.c: Use int, not EMACS_INT, for characters.
13530 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13531 EMACS_INT, for values that are known to be in character range.
13532 This doesn't fix any bugs but is the usual style inside Emacs and
13533 may generate better code on 32-bit machines.
13535 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13536 This is for reasons similar to the recent CHAR_STRING fix.
13537 * charset.c (Fencode_char): Check that character arg is actually
13538 a character. Pass an int to ENCODE_CHAR.
13539 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13540 wider than 'int', as a compile-time check to prevent future regressions
13543 * character.c (char_string): Remove unnecessary casts.
13545 Make sure a 64-bit char is never passed to CHAR_STRING.
13546 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13547 by silently ignoring the top 32 bits, allowing some values
13548 that were far too large to be valid characters.
13549 * character.h: Include <verify.h>.
13550 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13551 arguments are no wider than unsigned, as a compile-time check
13552 to prevent future regressions in this area.
13554 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
13555 (Fsubst_char_in_region):
13557 * xdisp.c (decode_mode_spec_coding):
13558 Adjust to CHAR_STRING's new requirement.
13559 * editfns.c (Finsert_char, Fsubst_char_in_region):
13560 * fns.c (concat): Check that character args are actually
13561 characters. Without this test, these functions did the wrong
13562 thing with wildly out-of-range values on 64-bit hosts.
13564 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13565 These casts should not be needed on 32-bit hosts, either.
13566 * keyboard.c (read_char):
13567 * lread.c (Fload): Remove casts to unsigned.
13569 * lisp.h (UNSIGNED_CMP): New macro.
13570 This fixes comparison bugs on 64-bit hosts.
13571 (ASCII_CHAR_P): Use it.
13572 * casefiddle.c (casify_object):
13573 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
13574 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
13575 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
13576 * dispextern.h (FACE_FROM_ID):
13577 * keyboard.c (read_char): Use UNSIGNED_CMP.
13579 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
13580 not to EMACS_INT, to avoid GCC warning.
13582 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13584 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13585 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
13586 isn't needed on 32-bit machines.
13588 * buffer.c (Fgenerate_new_buffer_name):
13589 Use EMACS_INT for count, not int.
13590 (advance_to_char_boundary): Return EMACS_INT, not int.
13592 * data.c (Qcompiled_function): Now static.
13594 * window.c (window_body_lines): Now static.
13596 * image.c (gif_load): Rename local to avoid shadowing.
13598 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
13599 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
13600 * alloc.c (make_save_value): Integer argument is now of type
13601 ptrdiff_t, not int.
13602 (mark_object): Use ptrdiff_t, not int.
13603 * lisp.h (pD): New macro.
13604 * print.c (print_object): Use it.
13606 * alloc.c: Use EMACS_INT, not int, to count objects.
13607 (total_conses, total_markers, total_symbols, total_vector_size)
13608 (total_free_conses, total_free_markers, total_free_symbols)
13609 (total_free_floats, total_floats, total_free_intervals)
13610 (total_intervals, total_strings, total_free_strings):
13611 Now EMACS_INT, not int. All uses changed.
13612 (Fgarbage_collect): Compute overall total using a double, so that
13613 integer overflow is less likely to be a problem. Check for overflow
13614 when converting back to an integer.
13615 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
13616 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
13617 These were 'int' variables that could overflow on 64-bit hosts;
13618 they were never used, so remove them instead of repairing them.
13619 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
13620 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
13621 Previously, this ceilinged at INT_MAX, but that doesn't work on
13623 (allocate_pseudovector): Don't use EMACS_INT when int would do.
13625 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
13626 (allocate_vectorlike): Check for ptrdiff_t overflow.
13627 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13628 when a (possibly-narrower) signed value would do just as well.
13629 We prefer using signed arithmetic, to avoid comparison confusion.
13631 * alloc.c: Catch some string size overflows that we were missing.
13632 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
13633 for convenience in STRING_BYTES_MAX.
13634 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
13635 The definition here is exact; the one in lisp.h was approximate.
13636 (allocate_string_data): Check for string overflow. This catches
13637 some instances we weren't catching before. Also, it catches
13638 size_t overflow on (unusual) hosts where SIZE_MAX <= min
13639 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
13640 and ptrdiff_t and EMACS_INT are both 64 bits.
13642 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
13643 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
13644 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
13646 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
13648 * alloc.c (Fmake_string): Check for out-of-range init.
13650 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
13652 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
13654 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
13656 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
13657 xg_get_default_scrollbar_width.
13659 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
13660 (int_gtk_range_get_value): Move to the scroll bar part of the file.
13661 (style_changed_cb): Call update_theme_scrollbar_width and call
13662 x_set_scroll_bar_default_width and xg_frame_set_char_size for
13663 all frames (Bug#8505).
13664 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
13665 Call gtk_window_set_resizable if HAVE_GTK3.
13666 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
13667 and height if HAVE_GTK3 (Bug#8505).
13668 (scroll_bar_width_for_theme): New variable.
13669 (update_theme_scrollbar_width): New function.
13670 (xg_get_default_scrollbar_width): Move code to
13671 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
13672 (xg_initialize): Call update_theme_scrollbar_width.
13674 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
13676 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
13678 2011-06-12 Martin Rudalics <rudalics@gmx.at>
13680 * frame.c (make_frame): Call other_buffer_safely instead of
13683 * window.c (temp_output_buffer_show): Call display_buffer with
13684 second argument Vtemp_buffer_show_specifiers and reset latter
13685 immediately after the call.
13686 (Vtemp_buffer_show_specifiers): New variable.
13687 (auto_window_vscroll_p, next_screen_context_lines)
13688 (Vscroll_preserve_screen_position): Remove leading asterisks from
13691 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
13693 Fix minor problems found by GCC 4.6.0 static checking.
13694 * buffer.c (Qclone_number): Remove for now, as it's unused.
13695 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
13696 (record_buffer): Remove unused local.
13697 * frame.c (other_visible_frames, frame_buffer_list): Now static.
13698 (set_frame_buffer_list): Remove; unused.

13702 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
13704 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
13705 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
13706 Define only if HAVE_GPM.
13707 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
13708 (update_hints_inhibit): Remove; never set. All uses removed.
13709 * widgetprv.h (emacsFrameClassRec): Remove decl.
13710 * window.c (delete_deletable_window): Now returns void, since it
13711 wasn't returning anything.
13712 (compare_window_configurations): Remove unused locals.
13713 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
13714 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
13715 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
13716 the same widths as pointers. This follows up on the 2011-05-06 patch.
13717 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
13718 * xterm.h: Likewise.

13724 (LISP_H): Add lib/intprops.h.
13726 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
13728 * image.c (gif_load): Add animation frame delay to the metadata.
13729 (syms_of_image): Use DEFSYM. New symbol `delay'.
13731 2011-06-11 Martin Rudalics <rudalics@gmx.at>
13733 * window.c (delete_deletable_window): Re-add.
13734 (Fset_window_configuration): Rewrite to handle dead buffers and
13735 consequently deletable windows.
13736 (window_tree, Fwindow_tree): Remove. Supply functionality in
13738 (compare_window_configurations): Simplify code.
13740 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
13742 * image.c (imagemagick_load_image): Fix type mismatch.
13743 (Fimagemagick_types): Likewise.
13745 * window.h (replace_buffer_in_windows): Declare.
13747 2011-06-11 Martin Rudalics <rudalics@gmx.at>
13749 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
13750 Qclone_number. Remove external declaration of Qdelete_window.
13751 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
13753 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
13754 Run Qbuffer_list_update_hook if allowed.
13755 (Fother_buffer): Rewrite doc-string. Major rewrite for new
13756 buffer list implementation.
13757 (other_buffer_safely): New function.
13758 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
13759 calls to replace_buffer_in_windows and
13760 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
13762 (record_buffer): Inhibit quitting and rewrite using quittable
13763 functions. Run Qbuffer_list_update_hook if allowed.
13764 (Frecord_buffer, Funrecord_buffer): New functions.
13765 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
13766 Move switch-to-buffer to window.el.
13767 (bury-buffer): Move to window.el.
13768 (Vbuffer_list_update_hook): New variable.
13770 * lisp.h (other_buffer_safely): Add prototype in buffer.c

13774 (Fwindow_frame): Remove EXFUN.
13775 (replace_buffer_in_all_windows): Remove prototype.
13776 (replace_buffer_in_windows_safely): Add prototype.
13778 * window.c: Declare Qdelete_window static again. Move down
13779 declaration of select_count.
13780 (Fnext_window, Fprevious_window): Rewrite doc-strings.
13781 (Fother_window): Move to window.el.
13782 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
13783 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.

13786 (replace_buffer_in_windows): Implement by calling
13787 Qreplace_buffer_in_windows.
13788 (replace_buffer_in_all_windows): Remove with some functionality
13789 moved into replace_buffer_in_windows_safely.
13790 (replace_buffer_in_windows_safely): New function.
13791 (select_window_norecord, select_frame_norecord): Move in front
13792 of run_window_configuration_change_hook. Remove now obsolete
13794 (Fset_window_buffer): Rewrite doc-string.
13795 Call Qrecord_window_buffer.
13796 (keys_of_window): Move binding for other-window to window.el.
13798 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
13800 * dispextern.h (struct image): Replace data member, whose int_val
13801 and ptr_val fields were not used by anything, with a single
13804 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
13805 (gif_clear_image, gif_load, imagemagick_load_image)

13861 (resize_frame_windows): Declare prototypes.
13863 * window.c (resize_window_apply): Make definition be "static" to
13864 match the prototype.
13866 2011-06-10 Martin Rudalics <rudalics@gmx.at>
13868 * window.c: Remove declarations of Qwindow_size_fixed,
13869 window_min_size_1, window_min_size_2, window_min_size,
13870 size_window, window_fixed_size_p, enlarge_window, delete_window.
13871 Remove static from declaration of Qdelete_window, it's

14239 (display_prop_intangible_p): Reimplement to call
14240 handle_display_spec instead of single_display_spec_intangible_p.

14245 lists with the argument STRING its top-level element.
14246 (display_prop_string_p): Fix the condition for processing a

14251 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
14252 value of a `display' property is a "replacing spec".
14253 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
14254 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
14255 the display property, but just return a value indicating whether
14256 the display property will replace the characters it covers.
14257 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and

14284 * gnutls.c: Use Emacs's memory allocators.
14285 Without this change, the gnutls library would invoke malloc etc.
14286 directly, which causes problems on non-SYNC_INPUT hosts, and which
14287 runs afoul of improving memory_full behavior. (Bug#8761)
14288 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
14289 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
14290 xfree instead of the default malloc, realloc, free.
14291 (Fgnutls_boot): No need to check for memory allocation failure,
14292 since xmalloc does that for us.

14312 * lisp.h (struct Lisp_Hash_Table):
14313 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
14314 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
14315 for hashes and hash indexes, instead of 'unsigned' and 'int'.
14316 * alloc.c (allocate_vectorlike):
14317 Check for overflow in vector size calculations.
14318 * ccl.c (ccl_driver):
14319 Check for overflow when converting EMACS_INT to int.
14320 * fns.c, image.c: Remove unnecessary static decls that would otherwise
14321 need to be updated by these changes.
14322 * fns.c (make_hash_table, maybe_resize_hash_table):
14323 Check for integer overflow with large hash tables.
14324 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
14325 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
14326 (SXHASH_REDUCE): New macro.
14327 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
14328 Use it instead of discarding useful hash info with large hash values.
14329 (sxhash_float): New function.
14330 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
14331 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
14332 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
14333 Rewrite to use FIXNUM_BITS, as this simplifies things.
14334 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
14335 Adjust signatures to match updated version of code.
14336 (consing_since_gc): Now EMACS_INT, since a single hash table can
14337 use more than INT_MAX bytes.
14339 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
14341 Make it possible to build with GCC-4.6+ -O2 -flto.

14345 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
14347 * minibuf.c (get_minibuffer, read_minibuf_unwind):
14348 Call minibuffer-inactive-mode.
14350 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
14352 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
14353 Update dependencies.
14355 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14357 * data.c (init_data): Remove code for UTS, this system is not
14360 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14362 Don't force ./temacs to start in terminal mode.
14364 * frame.c (make_initial_frame): Initialize faces in all cases, not
14365 only when CANNOT_DUMP is defined.
14366 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
14368 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14370 * dispnew.c (add_window_display_history): Use const for the string
14371 pointer. Remove declaration, not needed.
14373 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14375 Use 'inline', not 'INLINE'.
14376 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
14377 * alloc.c, fontset.c (INLINE): Remove.
14378 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
14379 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
14380 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
14381 * gmalloc.c (register_heapinfo): Use inline unconditionally.
14382 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
14384 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14386 Make it possible to run ./temacs.
14388 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
14389 syms_of_callproc does the same thing. Remove test for
14390 "initialized", do it in the caller.
14391 * emacs.c (main): Avoid calling set_initial_environment when dumping.
14393 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
14395 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
14396 (read_minibuf): Use get_minibuffer.
14397 (syms_of_minibuf): Use DEFSYM.
14398 (Qmetadata): New var.
14399 * data.c (Qbuffer): Don't make it static.
14400 (syms_of_data): Use DEFSYM.
14402 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14404 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
14405 (CCL_CODE_MIN): New macro.
14407 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
14409 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
14411 * eval.c (Qdebug): Now static.
14412 * lisp.h (Qdebug): Remove decl. This reverts a part of the
14413 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
14414 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
14416 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14418 * image.c: Various fixes to ImageMagick code comments.
14419 (Fimagemagick_types): Doc fix.
14421 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
14423 Minor fixes prompted by GCC 4.6.0 warnings.
14425 * xselect.c (converted_selections, conversion_fail_tag): Now static.
14427 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
14428 (x_clipboard_manager_save_all): Move extern decl to ...
14429 * xterm.h: ... here, so that it can be checked for consistency.
14431 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14433 * xselect.c (x_clipboard_manager_save_frame)
14434 (x_clipboard_manager_save_all): New functions.
14435 (Fx_clipboard_manager_save): Lisp function deleted.
14437 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
14438 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
14440 * xterm.h: Update prototype.
14442 2011-05-28 William Xu <william.xwl@gmail.com>
14444 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
14445 exiting (Bug#8239).
14447 2011-05-28 Jim Meyering <meyering@redhat.com>
14449 Avoid a sign-extension bug in crypto_hash_function.
14450 * fns.c (to_uchar): Define.
14451 (crypto_hash_function): Use it to convert some newly-signed
14452 variables to unsigned, to avoid sign-extension bugs. For example,
14453 without this change, (md5 "truc") would evaluate to
14454 45723a2aff78ff4fff7fff1114760e62 rather than the expected
14455 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
14456 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
14458 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14460 Integer overflow fixes.
14462 * dbusbind.c: Serial number integer overflow fixes.
14463 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
14464 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
14465 to hold a serial number that is too large for a fixnum.
14466 (Fdbus_method_return_internal, Fdbus_method_error_internal):
14467 Check for serial numbers out of range. Decode any serial number
14468 that was so large that it became a float. (Bug#8722)
14470 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
14471 (Fdbus_call_method, Fdbus_call_method_asynchronously):
14472 Use XFASTINT rather than XUINT when numbers are nonnegative.
14473 (xd_append_arg, Fdbus_method_return_internal):
14474 (Fdbus_method_error_internal): Likewise. Also, for unsigned
14475 arguments, check that Lisp number is nonnegative, rather than
14476 silently wrapping negative numbers around. (Bug#8722)
14477 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
14480 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
14482 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
14484 ccl: Add integer overflow checks.
14485 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
14486 (IN_INT_RANGE): New macros.
14487 (ccl_driver): Use them to check for integer overflow when
14488 decoding a CCL program. Many of the new checks are whether XINT (x)
14489 fits in int; it doesn't always, on 64-bit hosts. The new version
14490 doesn't catch all possible integer overflows, but it's an
14491 improvement. (Bug#8719)
14493 * alloc.c (make_event_array): Use XINT, not XUINT.
14494 There's no need for unsigned here.
14496 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
14497 This follows up to the 2011-05-06 change that substituted uintptr_t
14498 for EMACS_INT. This case wasn't caught back then.
14500 Rework Fformat to avoid integer overflow issues.
14501 * editfns.c: Include <float.h> unconditionally, as it's everywhere
14502 now (part of C89). Include <verify.h>.
14503 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
14504 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
14505 (Fformat): Avoid the prepass trying to compute sizes; it was only
14506 approximate and thus did not catch overflow reliably. Instead, walk
14507 through the format just once, formatting and computing sizes as we go,
14508 checking for integer overflow at every step, and allocating a larger
14509 buffer as needed. Keep track separately whether the format is
14510 multibyte. Keep only the most-recently calculated precision, rather
14511 than them all. Record whether each argument has been converted to
14512 string. Use EMACS_INT, not int, for byte and char and arg counts.
14513 Support field widths and precisions larger than INT_MAX. Avoid
14514 sprintf's undefined behavior with conversion specifications such as %#d
14515 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
14516 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
14517 formatting out-of-range floating point numbers with int
14518 formats. (Bug#8668)
14520 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
14522 * data.c: Avoid integer truncation in expressions involving floats.
14523 * data.c: Include <intprops.h>.
14524 (arith_driver): When there's an integer overflow in an expression
14525 involving floating point, convert the integers to floating point
14526 so that the resulting value does not suffer from catastrophic
14527 integer truncation. For example, on a 64-bit host (* 4
14528 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14529 Do not rely on undefined behavior after integer overflow.
14531 merge count_size_as_multibyte, parse_str_to_multibyte
14532 * character.c, character.h (count_size_as_multibyte):
14533 Rename from parse_str_to_multibyte; all uses changed.
14534 Check for integer overflow.
14535 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14536 since it's now a duplicate of the other. This is more of
14537 a character than a buffer op, so better that it's in character.c.
14538 * fns.c, print.c: Adjust to above changes.
14540 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14542 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14544 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14546 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14547 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14548 (x_clipboard_manager_save): Now static.
14549 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14551 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14552 (crypto_hash_function): Now static.
14553 Fix pointer signedness problems. Avoid unnecessary initializations.
14555 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14557 * termhooks.h (Vselection_alist): Make it terminal-local.
14559 * terminal.c (create_terminal): Initialize it.
14561 * xselect.c: Support for clipboard managers.
14562 (Vselection_alist): Move to termhooks.h as terminal-local var.
14563 (LOCAL_SELECTION): New macro.
14564 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14565 (symbol_to_x_atom): Remove gratuitous arg.
14566 (x_handle_selection_request, lisp_data_to_selection_data)
14567 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14568 (x_own_selection, x_get_local_selection, x_convert_selection):
14569 New arg, specifying work frame. Use terminal-local Vselection_alist.
14570 (some_frame_on_display): Delete unused function.
14571 (Fx_own_selection_internal, Fx_get_selection_internal)
14572 (Fx_disown_selection_internal, Fx_selection_owner_p)
14573 (Fx_selection_exists_p): New optional frame arg.
14574 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14575 (x_handle_selection_clear): Don't treat other terminals with the
14576 same keyboard specially. Use the terminal-local Vselection_alist.
14577 (x_clear_frame_selections): Use Frun_hook_with_args.
14579 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14581 * xterm.h: Add support for those atoms.
14583 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14585 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14586 (converted_selections, conversion_fail_tag): New global variables.
14587 (x_selection_request_lisp_error): Free the above.
14588 (x_get_local_selection): Remove unnecessary code.
14589 (x_reply_selection_request): Args changed; handle arbitrary array
14590 of converted selections stored in converted_selections.
14591 Separate the XChangeProperty and SelectionNotify steps.
14592 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14593 (x_convert_selection): New function.
14594 (x_handle_selection_event): Simplify.
14595 (x_get_foreign_selection): Don't ignore incoming requests while
14596 waiting for an answer; this will fail when we implement
14597 SAVE_TARGETS, and seems unnecessary anyway.
14598 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14599 (Vx_sent_selection_functions): Doc fix.
14601 2011-05-26 Leo Liu <sdl.web@gmail.com>
14603 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14605 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14607 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14609 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14610 for fringe update if it has periodic bitmap.
14611 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14612 and fringe_bitmap_periodic_p.
14614 * fringe.c (get_fringe_bitmap_data): New function.
14615 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14616 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14617 row. Mark glyph row for fringe update if periodicity changed.
14619 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14620 for fringe update unless it has periodic bitmap.
14622 2011-05-25 Kenichi Handa <handa@m17n.org>
14624 * xdisp.c (get_next_display_element): Set correct it->face_id for
14625 a static composition.
14627 2011-05-24 Leo Liu <sdl.web@gmail.com>
14630 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
14632 * fns.c (crypto_hash_function, Fsha1): New function.
14633 (Fmd5): Use crypto_hash_function.

14636 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14638 * gnutls.c: Remove unused macros.
14639 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14640 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14641 Remove macros that are defined and never used.
14642 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14644 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14646 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14647 (Fx_get_selection_internal): Minor cleanup.
14648 (Fx_own_selection_internal): Rename arguments for consistency with
14651 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14653 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.

14666 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
14667 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
14668 and add some more files.

14673 report_file_error introduced by the change from 2011-05-07.
14675 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14677 * systime.h (Time): Define only if emacs is defined.
14678 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14679 where the include path doesn't have X11/X.h by default. See
14680 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14682 2011-05-20 Kenichi Handa <handa@m17n.org>
14684 * composite.c (find_automatic_composition): Fix previous change.
14686 2011-05-20 Glenn Morris <rgm@gnu.org>
14688 * lisp.mk: New file, split from Makefile.in.
14689 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14690 (shortlisp): Remove.
14691 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14693 2011-05-19 Glenn Morris <rgm@gnu.org>
14695 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14696 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14697 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14698 (lisp): Set the order to that of loadup.el.
14699 (shortlisp): Make it a copy of $lisp.
14700 (SOME_MACHINE_LISP): Remove.
14701 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14702 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14704 2011-05-18 Kenichi Handa <handa@m17n.org>
14706 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14707 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14708 (find_automatic_composition): Mostly rewrite for efficiency.
14710 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14712 * makefile.w32-in: Update dependencies.
14714 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14716 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14717 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14719 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14721 Fix some integer overflow issues, such as string length overflow.
14723 * insdel.c (count_size_as_multibyte): Check for string overflow.
14725 * character.c (lisp_string_width): Check for string overflow.
14726 Use EMACS_INT, not int, for string indexes and lengths; in
14727 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14728 the resulting string length overflows an EMACS_INT; instead,
14729 report a string overflow if no precision given. When checking for
14730 precision exhaustion, use a check that cannot possibly have
14731 integer overflow. (Bug#8675)
14732 * character.h (lisp_string_width): Adjust to new signature.
14734 * alloc.c (string_overflow): New function.
14735 (Fmake_string): Use it. This doesn't change behavior, but saves
14736 a few bytes and will simplify future changes.
14737 * character.c (string_escape_byte8): Likewise.
14738 * lisp.h (string_overflow): New decl.
14740 Fixups, following up to the user-interface timestamp change.
14741 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14742 for UI timestamps, instead of unsigned long.
14743 * msdos.c (mouse_get_pos): Likewise.
14744 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14745 * w32gui.h (Time): Define by including "systime.h" rather than by
14746 declaring it ourselves. (Bug#8664)
14748 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14749 * image.c (clear_image_cache): Likewise.
14751 * term.c (term_mouse_position): Don't assume time_t wraparound.
14753 Be more systematic about user-interface timestamps.
14754 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14755 and sometimes 'EMACS_UINT', to represent these timestamps.
14756 This change causes it to use 'Time' uniformly, as that's what X uses.
14757 This makes the code easier to follow, and makes it easier to catch
14758 integer overflow bugs such as Bug#8664.
14759 * frame.c (Fmouse_position, Fmouse_pixel_position):
14760 Use Time, not unsigned long, for user-interface timestamps.
14761 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14762 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14763 * keyboard.h (last_event_timestamp): Likewise.
14764 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14765 * menu.h (xmenu_show): Likewise.
14766 * term.c (term_mouse_position): Likewise.
14767 * termhooks.h (struct input_event.timestamp): Likewise.
14768 (struct terminal.mouse_position_hook): Likewise.
14769 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14770 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14771 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14772 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14773 what it was before.
14774 * menu.h, termhooks.h: Include "systime.h", for Time.
14776 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14777 Don't assume that the difference between two unsigned long values
14778 can fit into an integer. At this point, we know button_down_time
14779 <= event->timestamp, so the difference must be nonnegative, so
14780 there's no need to cast the result if double-click-time is
14781 nonnegative, as it should be; check that it's nonnegative, just in
14782 case. This bug is triggered when events are more than 2**31 ms
14783 apart (about 25 days). (Bug#8664)
14785 * xselect.c (last_event_timestamp): Remove duplicate decl.
14786 (x_own_selection): Remove needless cast to unsigned long.
14788 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14789 that always fit in int. Use a sentinel instead of a counter, to
14790 avoid a temp and to allay GCC's concerns about possible int overflow.
14791 * frame.h (struct frame): Use int for menu_bar_items_used
14792 instead of EMACS_INT, since it always fits in int.
14794 * menu.c (grow_menu_items): Check for int overflow.
14796 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14798 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14799 Before, the code was not consistent. These values cannot exceed
14800 2**31 - 1 so there's no need to make them unsigned.
14801 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14802 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14803 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14805 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14807 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14808 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14809 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14810 presumably because the widths might not match.
14812 * window.c (size_window): Avoid needless test at loop start.
14814 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14816 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14818 2011-05-12 Drew Adams <drew.adams@oracle.com>
14820 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14822 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14824 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14825 `width' to `bar_area_x' and `bar_area_width', respectively.
14826 (x_scroll_run): Take account of fringe background extension.
14828 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14829 Rename local vars `left' and `width' to `bar_area_x' and
14830 `bar_area_width', respectively.
14831 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14832 background extension.
14834 2011-05-10 Jim Meyering <meyering@redhat.com>
14836 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14838 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14840 * image.c (Finit_image_library): Return t for built-in image types,
14841 like pbm and xbm. (Bug#8640)
14843 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14845 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14847 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14849 * w32console.c (Fset_screen_color): Doc fix.
14850 (Fget_screen_color): New function.
14851 (syms_of_ntterm): Defsubr it.
14853 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14854 unlink the temporary file if Fcall_process didn't create it in the
14856 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14857 child process will be redirected to a file specified with `:file'.
14858 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14859 cue to call_process_cleanup not to close that handle.
14861 2011-05-07 Ben Key <bkey76@gmail.com>
14863 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14864 one of two shell specific rules, either bootstrap-temacs-CMD or
14865 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14866 to the previous implementation of the bootstrap-temacs rule.
14867 The bootstrap-temacs-CMD rule is similar to the previous
14868 implementation of the bootstrap-temacs rule except that it
14869 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14872 These changes, along with some changes to nt/configure.bat,
14873 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14874 earlier fix to add support for --cflags and --ldflags options
14875 that include quotes so that it works whether make uses cmd or
14878 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14880 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14881 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14883 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14884 a string. Handle both cases.
14885 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14886 (Fdbus_register_method): Use Qinvalid_function.
14888 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14890 * makefile.w32-in: Update dependencies.
14891 (LISP_H): Add inttypes.h and stdin.h.
14892 (PROCESS_H): Add unistd.h.
14894 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14896 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14897 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14899 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14901 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14903 * term.c (vfatal): Remove stray call to va_end.
14904 It's not needed and the C Standard doesn't allow it here anyway.
14906 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14907 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14909 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14912 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14914 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14916 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14918 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14920 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14922 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14923 * charset.c (Fdefine_charset_internal): Don't initialize
14924 charset.code_space[15]. The value was garbage, on hosts with
14925 32-bit int (Bug#8600).
14927 * lread.c (read_integer): Be more consistent with string-to-number.
14928 Use string_to_number to do the actual conversion; this avoids
14929 rounding errors and fixes some other screwups. Without this fix,
14930 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14931 (digit_to_number): Move earlier, for benefit of read_integer.
14932 Return -1 if the digit is out of range for the base, -2 if it is
14933 not a digit in any supported base. (Bug#8602)
14935 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14937 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14938 to match comment at start of function. This also removes a
14939 GCC warning about overflow in a 32+64-bit port.
14941 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14943 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14944 Reported by Stefan Monnier in
14945 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14946 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14947 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14949 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14950 (EMACS_UINTPTR): Likewise, with uintptr_t.
14952 * lisp.h: Prefer 64-bit EMACS_INT if available.
14953 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14954 on 32-bit hosts that have 64-bit int, so that they can access
14956 However, temporarily disable this change unless the temporary
14957 symbol WIDE_EMACS_INT is defined.
14959 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14961 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14962 This removes an assumption that EMACS_INT and long are the same
14963 width as pointers. The assumption is true for Emacs porting targets
14964 now, but we want to make other targets possible.
14965 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14966 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14967 In the rest of the code, change types of integers that hold casted
14968 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14969 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14970 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14971 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14972 No need to cast type when ORing.
14973 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14974 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14975 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14976 assume EMACS_INT is the same width as char *.
14977 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14978 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14979 Remove no-longer-needed casts.
14980 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14981 (xg_tool_bar_help_callback, xg_make_tool_item):
14982 Use EMACS_INTPTR to hold an integer
14983 that will be cast to void *; this can avoid a GCC warning
14984 if EMACS_INT is not the same width as void *.
14985 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14986 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14987 (current_message_1, set_message_1):
14988 Use a local to convert to proper width without a cast.
14989 * xmenu.c (dialog_selection_callback): Likewise.
14991 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14992 Also, don't assume VALBITS / RAND_BITS is less than 5,
14993 and don't rely on undefined behavior when shifting a 1 left into
14995 * lisp.h (get_random): Change signature to match.
14997 * lread.c (hash_string): Use size_t, not int, for hash computation.
14998 Normally we prefer signed values; but hashing is special, because
14999 it's better to use unsigned division on hash table sizes so that
15000 the remainder is nonnegative. Also, size_t is the natural width
15001 for hashing into memory. The previous code used 'int', which doesn't
15002 retain enough info to hash well into very large tables.
15003 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
15005 * dbusbind.c: Don't possibly lose pointer info when converting.
15006 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15007 Use XPNTR rather than XHASH, so that the high-order bits of
15008 the pointer aren't lost when converting through void *.
15010 * eval.c (Fautoload): Don't double-shift a pointer.
15012 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
15014 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15016 * gnutls.c (DEF_GNUTLS_FN):
15017 * image.c (DEF_IMGLIB_FN): Make function pointers static.
15019 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
15021 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
15024 2011-05-05 Eli Zaretskii <eliz@gnu.org>
15026 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
15027 New version that can reserve upto 2GB of heap space.
15029 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
15031 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
15033 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
15035 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
15036 `gnutls_certificate_set_x509_key_file'.
15038 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
15040 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
15041 Update dependencies.
15043 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15045 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
15046 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
15047 Remove unused parameter `fildes'.
15048 * process.c (read_process_output, send_process): Don't pass it.
15050 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15052 Fix previous change: the library cache is defined in w32.c.
15053 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
15054 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
15056 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15058 Implement dynamic loading of GnuTLS on Windows.
15060 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
15061 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
15062 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15065 * gnutls.c (Qgnutls_dll): Define.
15066 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
15067 (gnutls_*): Declare function pointers.
15068 (init_gnutls_functions): New function to initialize function pointers.
15069 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
15070 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
15071 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15072 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
15073 (emacs_gnutls_write, emacs_gnutls_read)
15074 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
15075 (Fgnutls_available_p): New function.
15076 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
15077 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
15078 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
15080 * image.c: Include w32.h.
15081 (Vimage_type_cache): Delete.
15082 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
15083 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
15084 (w32_delayed_load): Move to w32.c.
15086 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
15088 * w32.c (QCloaded_from, Vlibrary_cache): Define.
15089 (w32_delayed_load): Move from image.c. When loading a library, record
15090 its filename in the :loaded-from property of the library id.
15091 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
15092 Initialize and staticpro them.
15093 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
15095 * process.c: Include lisp.h before w32.h, not after.
15096 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
15097 instead of gnutls_record_check_pending.
15099 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
15101 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
15103 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
15104 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
15107 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
15109 * xterm.c (x_set_frame_alpha): Do not set property on anything
15110 else than FRAME_X_OUTER_WINDOW (Bug#8608).
15112 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
15114 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
15116 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
15118 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
15119 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
15120 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

15125 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
15126 (Qgnutls_bootprop_callbacks_verify): Make static.
15128 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
15130 * callproc.c: Indentation fixup.
15132 * sysdep.c (wait_for_termination_1): Make static.
15133 (wait_for_termination, interruptible_wait_for_termination):
15134 Move after wait_for_termination_1.
15136 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
15138 * sysdep.c (interruptible_wait_for_termination): New function
15139 which is like wait_for_termination, but allows keyboard
15142 * callproc.c (Fcall_process): Add (:file "file") as an option for
15144 (Fcall_process_region): Ditto.
15146 2011-04-30 Eli Zaretskii <eliz@gnu.org>
15148 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
15149 rather than `XVECTOR (FOO)->size'.
15151 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
15152 inttypes.h, as a gnulib replacement is used if it not available in
15155 2011-04-21 Eli Zaretskii <eliz@gnu.org>
15157 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
15158 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
15159 of MOST_POSITIVE_FIXNUM. (Bug#8528)
15161 * coding.c (coding_alloc_by_realloc): Error out if destination
15162 will grow beyond MOST_POSITIVE_FIXNUM.
15163 (decode_coding_emacs_mule): Abort if there isn't enough place in
15164 charbuf for the composition carryover bytes. Reserve an extra
15165 space for up to 2 characters produced in a loop.
15166 (decode_coding_iso_2022): Abort if there isn't enough place in
15167 charbuf for the composition carryover bytes.
15169 2011-04-21 Eli Zaretskii <eliz@gnu.org>
15171 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
15172 aborting when %lld or %lll format is passed.
15173 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
15174 %llo or %llx format is passed. (Bug#8545)
15176 * window.c (window_scroll_line_based): Use a marker instead of
15177 simple variables to record original value of point. (Bug#7952)
15179 * doprnt.c (doprnt): Fix the case where a multibyte sequence
15180 produced by %s or %c overflows available buffer space. (Bug#8545)
15182 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
15184 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
15185 (SIZE_MAX): Move defn after all includes, as they might #define it.
15187 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15189 * w32.c (init_environment): Warn about defaulting HOME to C:\.
15191 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15193 * keyboard.c (Qdelayed_warnings_hook): Define.
15194 (command_loop_1): Run `delayed-warnings-hook'
15195 if Vdelayed_warnings_list is non-nil.
15196 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
15197 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
15199 2011-04-28 Eli Zaretskii <eliz@gnu.org>
15201 * doprnt.c (doprnt): Don't return value smaller than the buffer
15202 size if the message was truncated. (Bug#8545).
15204 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15206 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
15207 (Fx_window_property): #if-0 the whole functions, not just the bodies.
15209 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15211 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
15213 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
15215 * makefile.w32-in: Update dependencies.
15217 2011-04-27 Eli Zaretskii <eliz@gnu.org>
15219 Improve `doprnt' and its usage. (Bug#8545)
15220 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
15221 `format_end'. Remove support for %l as a conversion specifier.
15222 Don't use xrealloc. Improve diagnostics when the %l size modifier
15223 is used. Update the commentary.
15225 * eval.c (verror): Simplify calculation of size_t.
15227 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
15230 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
15232 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
15235 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15237 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
15238 This makes this file independent of the recent pseudovector change.
15240 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
15242 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
15244 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
15245 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
15246 Remove unused local.
15247 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
15249 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
15250 GCC 4.6.0 optimizes based on type-based alias analysis.
15251 For example, if b is of type struct buffer * and v of type struct
15252 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
15253 != &v->size, and therefore "v->size = 1; b->size = 2; return
15254 v->size;" must therefore return 1. This assumption is incorrect
15255 for Emacs, since it type-puns struct Lisp_Vector * with many other
15256 types. To fix this problem, this patch adds a new type struct
15257 vectorlike_header that documents the constraints on layout of vectors
15258 and pseudovectors, and helps optimizing compilers not get fooled
15259 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
15260 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
15261 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
15263 (XSETPVECTYPE): Rewrite in terms of new macro.
15264 (XSETPVECTYPESIZE): New macro, specifying both type and size.
15265 This is a bit clearer, and further avoids the possibility of
15266 undesirable aliasing.
15267 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
15268 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
15269 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
15270 since Lisp_Subr is a special case (no "next" field).
15271 (ASIZE): Now uses header.size rather than size.
15272 All previous uses of XVECTOR (foo)->size replaced to use this macro,
15273 to avoid the hassle of writing XVECTOR (foo)->header.size.
15274 (struct vectorlike_header): New type.
15275 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
15276 object, to help avoid aliasing.
15277 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
15278 (SUBRP): Likewise, since Lisp_Subr is a special case.
15279 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
15280 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
15281 (struct Lisp_Hash_Table): Combine first two members into a single
15282 struct vectorlike_header member. All uses of "size" and "next" members
15283 changed to be "header.size" and "header.next".
15284 * buffer.h (struct buffer): Likewise.
15285 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
15286 * frame.h (struct frame): Likewise.
15287 * process.h (struct Lisp_Process): Likewise.
15288 * termhooks.h (struct terminal): Likewise.
15289 * window.c (struct save_window_data, struct saved_window): Likewise.
15290 * window.h (struct window): Likewise.
15291 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
15292 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
15293 * buffer.c (init_buffer_once): Likewise.
15294 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
15296 * process.c (Fformat_network_address): Use local var for size,
15299 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
15301 Make the Lisp reader and string-to-float more consistent (Bug#8525)
15302 * data.c (atof): Remove decl; no longer used or needed.
15303 (digit_to_number): Move to lread.c.
15304 (Fstring_to_number): Use new string_to_number function, to be
15305 consistent with how the Lisp reader treats infinities and NaNs.
15306 Do not assume that floating-point numbers represent EMACS_INT
15307 without losing information; this is not true on most 64-bit hosts.
15308 Avoid double-rounding errors, by insisting on integers when
15309 parsing non-base-10 numbers, as the documentation specifies.
15310 * lisp.h (string_to_number): New decl, replacing ...
15311 (isfloat_string): Remove.
15312 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
15313 (read1): Do not accept +. and -. as integers; this
15314 appears to have been a coding error. Similarly, do not accept
15315 strings like +-1e0 as floating point numbers. Do not report
15316 overflow for integer overflows unless the base is not 10 which
15317 means we have no simple and reliable way to continue.
15318 Break out the floating-point parsing into a new
15319 function string_to_number, so that Fstring_to_number parses
15320 floating point numbers consistently with the Lisp reader.
15321 (digit_to_number): Move here from data.c. Make it static inline.
15322 (E_CHAR, EXP_INT): Remove, replacing with ...
15323 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
15324 (string_to_number): New function, replacing isfloat_string.
15325 This function checks for valid syntax and produces the resulting
15326 Lisp float number too. Rework it so that string-to-number
15327 no longer mishandles examples like "1.0e+". Use strtoumax,
15328 so that overflow for non-base-10 numbers is reported only when
15329 there's no portable and simple way to convert to floating point.
15331 * textprop.c (set_text_properties_1): Rewrite for clarity,
15332 and to avoid GCC warning about integer overflow.
15334 * intervals.h (struct interval): Use EMACS_INT for members
15335 where EMACS_UINT might cause problems. See
15336 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
15337 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
15338 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
15340 (offset_intervals): Tell GCC not to worry about length overflow
15341 when negating a negative length.
15343 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
15344 (overrun_check_free): Likewise.
15346 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
15347 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
15350 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15351 (gnutls_make_error): Rename local to avoid shadowing.
15352 (gnutls_emacs_global_deinit): ifdef out; not used.
15353 (Fgnutls_boot): Use const for pointer to readonly storage.
15354 Comment out unused local. Fix pointer signedness problems.
15356 * lread.c (openp): Don't stuff size_t into an 'int'.
15357 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
15358 about possible signed overflow.
15360 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15361 (GDK_KEY_g): Don't define if already defined.
15362 (xg_prepare_tooltip): Avoid pointer signedness problem.
15363 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
15365 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
15366 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
15368 * xfns.c (Fx_window_property): Simplify a bit,
15369 to make a bit faster and to avoid GCC 4.6.0 warning.
15370 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
15372 * fns.c (internal_equal): Don't assume size_t fits in int.
15374 * alloc.c (compact_small_strings): Tighten assertion a little.
15376 Replace pEd with more-general pI, and fix some printf arg casts.
15377 * lisp.h (pI): New macro, generalizing old pEd macro to other
15378 conversion specifiers. For example, use "...%"pI"d..." rather
15379 than "...%"pEd"...".
15380 (pEd): Remove. All uses replaced with similar uses of pI.
15381 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
15382 * alloc.c (check_pure_size): Don't overflow by converting size to int.
15383 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
15384 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
15385 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
15386 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
15387 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
15389 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
15390 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
15391 * print.c (safe_debug_print, print_object): Likewise.
15392 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
15394 Use pI instead of if-then-else-abort. Use %p to avoid casts,
15395 avoiding the 0 flag, which is not portable.
15396 * process.c (Fmake_network_process): Use pI to avoid cast.
15397 * region-cache.c (pp_cache): Likewise.
15398 * xdisp.c (decode_mode_spec): Likewise.
15399 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
15400 behavior on 64-bit hosts with printf arg.
15401 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
15402 (x_stop_queuing_selection_requests): Likewise.
15403 (x_get_window_property): Don't truncate byte count to an 'int'
15406 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
15407 here, since it parses constructs like leading '-' and spaces,
15408 which are not wanted; and it overflows with large numbers.
15409 Instead, simply match F[0-9]+, which is what is wanted anyway.
15411 * alloc.c: Remove unportable assumptions about struct layout.
15412 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
15413 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
15414 (allocate_vectorlike, make_pure_vector): Use the new macros,
15415 plus offsetof, to remove unportable assumptions about struct layout.
15416 These assumptions hold on all porting targets that I know of, but
15417 they are not guaranteed, they're easy to remove, and removing them
15418 makes further changes easier.
15420 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
15421 This doesn't fix a bug but makes the code clearer.
15422 (string_overrun_cookie): Now const. Use initializers that
15423 don't formally overflow signed char, to avoid warnings.
15424 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
15425 can cause Emacs to crash when string overrun checking is enabled.
15426 (allocate_buffer): Don't assume sizeof (struct buffer) is a
15427 multiple of sizeof (EMACS_INT); it need not be, if
15428 alignof(EMACS_INT) < sizeof (EMACS_INT).
15429 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
15431 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
15433 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
15435 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
15437 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
15438 supposed to be handshaking. (Bug#8556)
15439 Reported by Paul Eggert <eggert@cs.ucla.edu>.
15441 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
15443 * lisp.h (Qdebug): List symbol.
15444 * eval.c (Qdebug): Restore global linkage.
15445 * keyboard.c (debug-on-event): New variable.
15446 (handle_user_signal): Break into debugger when debug-on-event
15447 matches the current signal symbol.
15449 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
15451 * alloc.c (check_sblock, check_string_bytes)
15452 (check_string_free_list): Convert to standard C.
15454 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
15456 * w32.c (emacs_gnutls_push): Fix typo.
15458 2011-04-25 Eli Zaretskii <eliz@gnu.org>
15460 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
15461 "cast to pointer from integer of different size".
15463 Improve doprnt and its use in verror. (Bug#8545)
15464 * doprnt.c (doprnt): Document the set of format control sequences
15465 supported by the function. Use SAFE_ALLOCA instead of always
15468 * eval.c (verror): Don't limit the buffer size at size_max-1, that
15469 is one byte too soon. Don't use xrealloc; instead xfree and
15472 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
15474 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
15477 * gnutls.c: Renamed global_initialized to
15478 gnutls_global_initialized. Added internals for the
15479 :verify-hostname-error, :verify-error, and :verify-flags
15480 parameters of `gnutls-boot' and documented those parameters in the
15481 docstring. Start callback support.
15482 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
15483 unless a fatal error occurred. Call gnutls_alert_send_appropriate
15484 on error. Return error code.
15485 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
15486 (emacs_gnutls_read): Likewise.
15487 (Fgnutls_boot): Return handshake error code.
15488 (emacs_gnutls_handle_error): New function.
15489 (wsaerror_to_errno): Likewise.

15526 to changes in oldXMenu/XMenu.h from 2011-04-16.
15527 (struct XMenu): Declare `help_text' `const char **'.

15544 changes in globals.h immediately force recompilation.
15545 (TAGS): Depend on $(CURDIR)/m/intel386.h and
15546 $(CURDIR)/s/ms-w32.h.
15547 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

15551 <char-direction-table>: Deleted.
15553 2011-04-23 Eli Zaretskii <eliz@gnu.org>
15555 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
15556 * doprnt.c: Include limits.h.
15557 (SIZE_MAX): New macro.
15558 (doprnt): Return a size_t value. 2nd arg is now size_t.
15559 Many local variables are now size_t instead of int or unsigned.
15560 Improve overflow protection. Support `l' modifier for integer
15561 conversions. Support %l conversion. Don't assume an EMACS_INT
15562 argument for integer conversions and for %c.
15564 * lisp.h (doprnt): Restore prototype.
15566 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
15567 $(SRC)/character.h.
15569 * Makefile.in (base_obj): Add back doprnt.o.
15571 * deps.mk (doprnt.o): Add back prerequisites.
15572 (callint.o): Depend on character.h.
15574 * eval.c (internal_lisp_condition_case): Include the handler
15575 representation in the error message.
15576 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
15577 when breaking from the loop.
15579 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
15581 * callint.c (Fcall_interactively): When displaying error message
15582 about invalid control letter, pass the character's codepoint, not
15583 a pointer to its multibyte form. Improve display of the character
15584 in octal and display also its hex code.
15586 * character.c (char_string): Use %x to display the (unsigned)
15587 codepoint of an invalid character, to avoid displaying a bogus
15590 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15591 `error', not SYMBOL_NAME itself.
15593 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
15594 character arguments to `error'.
15596 * charset.c (check_iso_charset_parameter): Fix incorrect argument
15597 to `error' in error message about FINAL_CHAR argument. Make sure
15598 FINAL_CHAR is a character, and use %c when it is passed as
15599 argument to `error'.
15601 2011-04-23 Eli Zaretskii <eliz@gnu.org>

15789 ns_descriptor_to_entity that were caused by using free to
15790 deallocate memory blocks that were allocated by xmalloc (via
15791 xstrdup). This caused Emacs to crash when compiled with

15812 * process.c (send_process): Adjust to the new signatures of
15813 emacs_write and emacs_gnutls_write. Do not attempt to store

16149 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
16150 * dispextern.h (bidi_dump_cached_states): Remove, since it's
16151 exported only to the debugger.

16154 * atimer.h (run_all_atimers): Remove; not exported.
16156 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
16157 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
16158 was inaccessible from Lisp.
16159 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
16160 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
16162 alloc.c: Import and export fewer symbols, and remove unused items.
16163 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
16165 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
16166 it's not optimized away by whole-program optimization.

16179 (mark_backtrace): Define only if BYTE_MARK_STACK.
16180 * xdisp.c (message_enable_multibyte): Now static.
16182 Declare Lisp_Object Q* variables to be 'static' if not exported.
16183 This makes it easier for human readers (and static analyzers)
16184 to see whether these variables are used from other modules.
16185 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

16195 Remove decls of unexported vars.
16196 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
16198 * lisp.h (DEFINE_FUNC): Make sname 'static'.
16200 Make Emacs functions such as Fatom 'static' by default.
16201 This makes it easier for human readers (and static analyzers)
16202 to see whether these functions can be called from other modules.
16203 DEFUN now defines a static function. To make the function external
16204 so that it can be used in other C modules, use the new macro DEFUE.

16210 Remove decls, since these functions are now static.
16211 (Funintern, Fget_internal_run_time): New decls, since these functions
16212 were already external.
16214 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

16222 Mark functions with DEFUE instead of DEFUN,
16223 if they are used in other modules.
16224 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
16225 decls for now-static functions.
16226 * buffer.h (Fdelete_overlay): Remove decl.
16227 * callproc.c (Fgetenv_internal): Mark as internal.

16236 * image.c (Finit_image_library): New forward static decl.
16237 * insdel.c (Fcombine_after_change_execute): Make forward decl static.

16239 (Fremove_list_of_text_properties): Remove decls.
16240 * keyboard.c (Fthis_command_keys): Remove decl.
16241 (Fcommand_execute): New forward static decl.

16262 2011-04-13 Eli Zaretskii <eliz@gnu.org>
16264 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
16265 when at ZV. (Bug#8487)
16267 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
16269 * charset.c (Fclear_charset_maps): Use xfree instead of free.

16275 * xsettings.c (read_and_apply_settings): Likewise.
16277 * alloc.c (overrun_check_malloc, overrun_check_realloc)
16278 (overrun_check_free): Protoize.
16280 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
16282 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
16283 since callers should never pass a negative size.
16284 Change the signature to match that of plain 'read' and 'write'; see
16285 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
16286 * lisp.h: Update prototypes of emacs_write and emacs_read.
16288 2011-04-11 Eli Zaretskii <eliz@gnu.org>
16290 * xdisp.c (redisplay_window): Don't try to determine the character
16291 position of the scroll margin if the window start point w->startp
16292 is outside the buffer's accessible region. (Bug#8468)
16294 2011-04-10 Eli Zaretskii <eliz@gnu.org>
16296 Fix write-region and its subroutines for buffers > 2GB.
16297 * fileio.c (a_write, e_write): Modify declaration of arguments and
16298 local variables to support buffers larger than 2GB.
16299 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
16301 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
16302 argument, local variables, and return value.
16304 * lisp.h: Update prototypes of emacs_write and emacs_read.
16306 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
16308 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
16310 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
16312 Fix more problems found by GCC 4.6.0's static checks.
16314 * xdisp.c (vmessage): Use a better test for character truncation.
16316 * charset.c (load_charset_map): <, not <=, for optimization,
16317 and to avoid potential problems with integer overflow.
16318 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
16319 * casetab.c (set_identity, shuffle): Likewise.
16320 * editfns.c (Fformat): Likewise.
16321 * syntax.c (skip_chars): Likewise.
16323 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
16324 This also lets GCC 4.6.0 generate slightly better loop code.
16326 * callint.c (Fcall_interactively): <, not <=, for optimization.
16327 (Fcall_interactively): Count the number of arguments produced,
16328 not the number of arguments given. This is simpler and lets GCC
16329 4.6.0 generate slightly better code.
16331 * ftfont.c: Distingish more carefully between FcChar8 and char.
16332 The previous code passed unsigned char * to a functions like
16333 strlen and xstrcasecmp that expect char *, which does not
16334 conform to the C standard.
16335 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
16336 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
16337 char * when the C standard requires it.
16339 * keyboard.c (read_char): Remove unused var.
16341 * eval.c: Port to Windows vsnprintf (Bug#8435).
16342 Include <limits.h>.
16343 (SIZE_MAX): Define if the headers do not.
16344 (verror): Do not give up if vsnprintf returns a negative count.
16345 Instead, grow the buffer. This ports to Windows vsnprintf, which
16346 does not conform to C99. Problem reported by Eli Zaretskii.
16347 Also, simplify the allocation scheme, by avoiding the need for
16348 calling realloc, and removing the ALLOCATED variable.
16350 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
16352 Remove invocations of doprnt, as Emacs now uses vsnprintf.
16353 But keep the doprint source code for now, as we might revamp it
16354 and use it again (Bug#8435).
16355 * lisp.h (doprnt): Remove.
16356 * Makefile.in (base_obj): Remove doprnt.o.
16357 * deps.mk (doprnt.o): Remove.
16359 error: Print 32- and 64-bit integers portably (Bug#8435).
16360 Without this change, on typical 64-bit hosts error ("...%d...", N)
16361 was used to print both 32- and 64-bit integers N, which relied on
16362 undefined behavior.
16363 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
16364 * lisp.h (error, verror): Mark as printf-like functions.
16365 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
16366 Report overflow in size calculations when allocating printf buffer.
16367 Do not truncate output string at its first null byte.
16368 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
16369 Truncate the output at a character boundary, since vsnprintf does not
16371 * charset.c (check_iso_charset_parameter): Convert internal
16372 character to string before calling 'error', since %c now has the
16374 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
16375 overflow when computing char to be passed to 'error'. Do not
16376 pass Lisp_Object to 'error'; pass the integer instead.
16377 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
16378 formatted with plain %d.
16380 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
16382 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
16384 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
16386 * xterm.c (x_catch_errors): Remove duplicate declaration.
16388 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
16390 * xdisp.c, lisp.h (message_nolog): Remove; unused.
16392 2011-04-10 Jim Meyering <meyering@redhat.com>
16394 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
16395 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
16396 return ssize_t not "int", and use size_t as the buffer length.
16397 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
16398 * gnutls.h: Update declarations.
16399 * process.c (read_process_output): Use ssize_t, to match.
16400 (send_process): Likewise.
16402 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16404 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
16406 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16408 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
16409 Use unsigned char, to match FcChar8 type definition.
16411 * xterm.c (handle_one_xevent):
16412 * xmenu.c (create_and_show_popup_menu):
16413 * xselect.c (x_decline_selection_request)
16414 (x_reply_selection_request): Avoid type-punned deref of X events.
16416 2011-04-09 Eli Zaretskii <eliz@gnu.org>
16418 Fix some uses of `int' instead of EMACS_INT.
16419 * search.c (string_match_1, fast_string_match)
16420 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
16421 (scan_buffer, find_next_newline_no_quit)
16422 (find_before_next_newline, search_command, Freplace_match)
16423 (Fmatch_data): Make some `int' variables be EMACS_INT.
16425 * xdisp.c (display_count_lines): 3rd argument and return value now
16426 EMACS_INT. All callers changed.
16427 (pint2hrstr): Last argument is now EMACS_INT.
16429 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
16430 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
16431 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

16442 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
16443 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
16445 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
16446 (encode_invocation_designation): Last argument P_NCHARS is now
16448 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
16449 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
16451 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
16454 * ccl.c (Fccl_execute_on_string): Declare some variables
16457 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
16459 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
16461 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
16463 * process.c (Fformat_network_address): Doc fix.
16465 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
16467 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
16469 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
16471 * keyboard.c (read_char): Call Lisp function help-form-show,
16472 instead of using internal_with_output_to_temp_buffer.

16489 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
16491 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
16493 Fix more problems found by GCC 4.6.0's static checks.
16495 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

16499 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
16501 * xdisp.c (vmessage): Mark as a printf-like function.
16503 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

16507 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
16508 printf-like functions.
16509 (tiff_load): Add casts to remove these marks before passing them
16510 to system-supplied API.
16512 * eval.c (Fsignal): Remove excess argument to 'fatal'.
16514 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
16515 This avoids several warnings with gcc -Wstrict-overflow.
16516 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
16517 directly, rather than having caller test rule sign. This avoids
16518 some unnecessary tests.
16519 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
16520 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
16521 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
16523 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16524 (xfont_open): Avoid unnecessary tests.
16526 * composite.c (composition_gstring_put_cache): Use unsigned integer.
16528 * composite.h, composite.c (composition_gstring_put_cache):
16529 Use EMACS_INT, not int, for length.
16531 * composite.h (COMPOSITION_DECODE_REFS): New macro,
16532 breaking out part of COMPOSITION_DECODE_RULE.
16533 (COMPOSITION_DECODE_RULE): Use it.
16534 * composite.c (get_composition_id): Remove unused local vars,
16535 by using the new macro.
16537 * textprop.c (set_text_properties_1): Change while to do-while,
16538 since the condition is always true at first.
16540 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16541 (interval_deletion_adjustment): Return unsigned value.
16544 * process.c (list_processes_1, create_pty, read_process_output):
16545 (exec_sentinel): Remove vars that were set but not used.
16546 (create_pty): Remove unnecessary "volatile"s.
16547 (Fnetwork_interface_info): Avoid possibility of int overflow.
16548 (read_process_output): Do adaptive read buffering even if carryover.
16549 (read_process_output): Simplify nbytes computation if buffered.
16551 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
16553 * syntax.c (scan_words): Remove var that was set but not used.
16554 (update_syntax_table): Use unsigned instead of int.
16556 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
16557 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
16558 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
16560 * print.c (print_error_message): Avoid int overflow.
16562 * font.c (font_list_entities): Redo for clarity,
16563 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
16565 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
16566 (font_score): Avoid potential overflow in diff calculation.
16568 * fns.c (substring_both): Remove var that is set but not used.
16569 (sxhash): Redo loop for clarity and to avoid wraparound warning.
16571 * eval.c (funcall_lambda): Rename local to avoid shadowing.
16573 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
16574 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
16575 can always succeed if overflow has undefined behavior.
16577 * search.c (boyer_moore, wordify): Remove vars set but not used.
16578 (wordify): Omit three unnecessary tests.
16580 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
16581 All callers changed. This avoids the need for an unused var.
16583 * casefiddle.c (casify_region): Remove var that is set but not used.
16585 * dired.c (file_name_completion): Remove var that is set but not used.
16587 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
16589 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16590 (Finsert_file_contents): Remove unnecessary code checking fd.
16592 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
16593 Check for integer overflow on size calculations.
16595 * buffer.c (Fprevious_overlay_change): Remove var that is set
16598 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16599 Remove vars that are set but not used.
16600 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16601 (timer_check_2): Mark vars as initialized.
16603 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16605 * image.c (lookup_image): Remove var that is set but not used.
16606 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16608 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16609 that are set but not used.
16611 * xfns.c (make_invisible_cursor): Don't return garbage
16612 if XCreateBitmapFromData fails (Bug#8410).
16614 * xselect.c (x_get_local_selection, x_handle_property_notify):
16615 Remove vars that are set but not used.
16617 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
16618 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
16620 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
16621 Remove var that is set but not used.
16622 (scroll_bar_windows_size): Now size_t, not int.
16623 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16624 Check for overflow.
16626 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16627 (map_tty_color) [!defined MSDOS]: Likewise.
16629 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16631 * coding.c: Remove vars that are set but not used.
16632 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
16633 All callers changed.
16634 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
16635 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
16636 (decode_coding_charset): Remove vars that are set but not used.
16638 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
16639 that is set but not used.
16641 * print.c (print_object): Remove var that is set but not used.
16643 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16644 The gnulib version avoids calling malloc in the usual case,
16645 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16646 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16647 * filelock.c (current_lock_owner): Likewise.
16648 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16649 * sysdep.c: Include allocator.h, careadlinkat.h.
16650 (emacs_no_realloc_allocator): New static constant.
16651 (emacs_readlink): New function.
16652 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16653 ../lib/careadlinkat.h.
16655 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
16657 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
16658 first non-nil return value).
16660 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
16662 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
16663 if not defined (Bug#8403).
16665 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16667 * xdisp.c (display_count_lines): Remove parameter `start',
16668 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16669 (get_char_face_and_encoding): Remove parameter `multibyte_p',
16670 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

16672 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
16673 and thereabouts. All callers changed.
16674 (get_per_char_metric): Remove parameter `f', unused since
16675 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
16677 2011-04-02 Jim Meyering <meyering@redhat.com>
16679 do not dereference NULL upon failed strdup
16680 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16681 (ns_get_family): Likewise.
16683 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16685 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16687 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16689 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16692 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16694 Add lexical binding.
16696 * window.c (Ftemp_output_buffer_show): New fun.
16697 (Fsave_window_excursion):
16698 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
16700 * lread.c (lisp_file_lexically_bound_p): New function.
16701 (Fload): Bind Qlexical_binding.
16702 (readevalloop): Remove `evalfun' arg.
16703 Bind Qinternal_interpreter_environment.
16704 (Feval_buffer): Bind Qlexical_binding.
16705 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16707 (syms_of_lread): Declare `lexical-binding'.
16709 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16711 * keyboard.c (eval_dyn): New fun.
16712 (menu_item_eval_property): Use it.
16714 * image.c (parse_image_spec): Use Ffunctionp.
16716 * fns.c (concat, mapcar1): Accept byte-code-functions.
16718 * eval.c (Fsetq): Handle lexical vars.
16719 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16720 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16721 (FletX, Flet): Obey lexical binding.
16722 (Fcommandp): Handle closures.
16723 (Feval): New `lexical' arg.
16724 (eval_sub): New function extracted from Feval. Use it almost
16725 everywhere where Feval was used. Look up vars in lexical env.
16727 (Ffunctionp): Move from subr.el.
16728 (Ffuncall): Handle closures.
16729 (apply_lambda): Remove `eval_flags'.
16730 (funcall_lambda): Handle closures and new byte-code-functions.
16731 (Fspecial_variable_p): New function.
16732 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16733 but without exporting it to Lisp.
16735 * doc.c (Fdocumentation, store_function_docstring):
16736 * data.c (Finteractive_form): Handle closures.
16738 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16741 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16743 (exec_byte_code): New function extracted from Fbyte_code to handle new
16744 calling convention for byte-code-functions. Add new byte-codes.
16746 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
16748 * alloc.c (Fmake_symbol): Init new `declared_special' field.
16750 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16752 * xdisp.c (redisplay_internal): Fix prototype.
16754 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16756 * xdisp.c (SCROLL_LIMIT): New macro.
16757 (try_scrolling): Use it when setting scroll_limit.
16758 Limit scrolling to 100 screen lines.
16759 (redisplay_window): Even when falling back on "recentering",
16760 position point in the window according to scroll-conservatively,
16761 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16763 (try_scrolling): When point is above the window, allow searching
16764 as far as scroll_max, or one screenful, to compute vertical
16765 distance from PT to the scroll margin position. This prevents
16766 try_scrolling from unnecessarily failing when
16767 scroll-conservatively is set to a value slightly larger than the
16768 window height. Clean up the case of PT below the margin at bottom
16769 of window: scroll_max can no longer be INT_MAX. When aggressive
16770 scrolling is in use, don't let point enter the opposite scroll
16771 margin as result of the scroll.
16772 (syms_of_xdisp) <scroll-conservatively>: Document the
16773 threshold of 100 lines for never-recentering scrolling.
16775 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16777 * dispextern.h (move_it_by_lines):
16778 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
16779 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
16780 (message_log_check_duplicate): Remove parameters `prev_bol' and
16781 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16782 (redisplay_internal): Remove parameter `preserve_echo_area',
16783 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16785 * indent.c (Fvertical_motion):
16786 * window.c (window_scroll_pixel_based, Frecenter):
16787 Don't pass `need_y_p' to `move_it_by_lines'.
16789 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16791 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16792 steal a few bits to be more compact.
16793 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16794 Remove unneeded casts.
16796 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16798 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16800 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16801 binding" message (bug#7967).
16803 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16805 Fix more problems found by GCC 4.6.0's static checks.
16807 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16808 Remove unused local var.
16810 * editfns.c (Fmessage_box): Remove unused local var.
16812 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16813 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16814 Omit unused local vars.
16815 * window.c (shrink_windows): Omit unused local var.
16816 * menu.c (digest_single_submenu): Omit unused local var.
16817 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16818 Omit unused local var.
16820 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16821 Don't assume string length fits in int.
16822 (keyremap_step, read_key_sequence): Use size_t for sizes.
16823 (read_key_sequence): Don't check last_real_key_start redundantly.
16825 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
16826 instead of alloca (Bug#8344).
16828 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16829 (Fbacktrace_frame): Don't assume nframes fits in int.
16831 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
16833 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
16836 * term.c (produce_glyphless_glyph): Remove unnecessary test.
16838 * cm.c (calccost): Turn while-do into do-while, for clarity.
16840 * keyboard.c (syms_of_keyboard): Use the same style as later
16841 in this function when indexing through an array. This also
16842 works around GCC bug 48267.
16844 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16846 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16848 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16849 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16851 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16852 This avoids undefined behavior on integer overflow, and is a bit
16853 more convenient anyway since it is compared to a size_t variable.
16855 Variadic C functions now count arguments with size_t, not int.
16856 This avoids an unnecessary limitation on 64-bit machines, which
16857 caused (substring ...) to crash on large vectors (Bug#8344).
16858 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
16859 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

16867 * fns.c (concat): Likewise.
16868 * frame.c (x_set_frame_parameters): Likewise.
16869 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16870 0 if not found, not -1. All callers changed.
16872 * alloc.c (garbage_collect): Don't assume stack size fits in int.
16873 (stack_copy_size): Now size_t, not int.
16874 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
16876 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
16878 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
16879 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
16880 All callers changed.
16882 * lisp.h (multibyte_char_to_unibyte):
16883 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
16884 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

16888 * keymap.c (push_key_description):
16889 * search.c (Freplace_match):
16890 * xdisp.c (message_dolog, set_message_1): All callers changed.
16892 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
16894 * keyboard.c (safe_run_hook_funcall): New function.
16895 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
16896 don't set the hook to nil, but remove the offending function instead.
16897 (Qcommand_hook_internal): Remove, unused.
16898 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
16899 Vcommand_hook_internal.
16901 * eval.c (enum run_hooks_condition): Remove.
16902 (funcall_nil, funcall_not): New functions.
16903 (run_hook_with_args): Call each function through a `funcall' argument.
16904 Remove `cond' argument, now redundant.
16905 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
16906 (Frun_hook_with_args_until_failure): Adjust accordingly.
16907 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
16909 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

16913 * print.c (strout): Remove parameter `multibyte', unused since
16914 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
16916 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
16917 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
16918 All callers changed.
16920 * w32.c (_wsa_errlist): Use braces for struct initializers.
16922 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
16923 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
16924 All callers changed.
16925 (string_buffer_position): Likewise. Also, make static (it's never

17079 * buffer.c (Fkill_all_local_variables):
17080 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
17082 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
17083 unconditionally since it does the check itself.
17085 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
17087 Fix more problems found by GCC 4.5.2's static checks.
17089 * coding.c (encode_coding_raw_text): Avoid unnecessary test
17090 the first time through the loop, since we know p0 < p1 then.
17091 This also avoids a gcc -Wstrict-overflow warning.
17093 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
17094 leading to a memory leak, possible in functions like
17095 load_charset_map_from_file that can allocate an unbounded number
17096 of objects (Bug#8318).
17098 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
17099 that could (at least in theory) be that large.
17101 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
17102 This is less likely to overflow, and avoids undefined behavior if
17103 overflow does occur. All callers changed. Use strtoul to scan
17104 for the unsigned long integer.
17105 (pint2hrstr): Simplify and tune code slightly.
17106 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

17121 * process.c (Fmake_network_process): Use socklen_t, not int,
17122 where POSIX says socklen_t is required in portable programs.
17123 This fixes a porting bug on hosts like 64-bit HP-UX, where
17124 socklen_t is wider than int (Bug#8277).
17125 (Fmake_network_process, server_accept_connection):
17126 (wait_reading_process_output, read_process_output):
17129 * process.c: Rename or move locals to avoid shadowing.

17139 Make tparam.h and terminfo.c consistent.
17140 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
17141 Include tparam.h instead, since it declares them.
17142 * cm.h (PC): Remove extern decl; tparam.h now does this.
17143 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
17144 * terminfo.c: Include tparam.h, to check interfaces.
17145 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
17146 (tparam): Adjust signature to match interface in tparam.h;
17147 this removes some undefined behavior. Check that outstring and len
17148 are zero, which they always are with Emacs.
17149 * tparam.h (PC, BC, UP): New extern decls.
17151 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
17152 (xftfont_open): Rename locals to avoid shadowing.

17169 (find_automatic_composition, composition_adjust_point): Likewise.
17170 (composition_update_it): Mark var as initialized.
17171 (find_automatic_composition): Mark vars as initialized,
17172 with a FIXME (Bug#8290).

17176 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
17177 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
17178 (BUF_DEC_POS): Be more systematic about renaming local temporaries
17179 to avoid shadowing.

17191 Fix pointer signedness.
17192 (alsa_choose_format): Remove unused local var.
17193 (wav_play): Initialize a variable to 0, to prevent undefined
17194 behavior (Bug#8278).
17196 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
17198 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
17200 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
17201 clobbering (Bug#8298).
17202 * sysdep.c (sys_subshell): Likewise.
17203 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
17205 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
17206 This should get cleaned up, so that child_setup has the
17207 same signature on all platforms.
17209 * callproc.c (call_process_cleanup): Now static.
17210 (relocate_fd): Rename locals to avoid shadowing.
17212 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
17214 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
17215 not to be necessary, and produces flickering.
17217 2011-03-20 Glenn Morris <rgm@gnu.org>
17219 * config.in: Remove file.
17221 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

17266 Define only if needed.
17268 * unexelf.c (unexec): Name an expression,
17269 to avoid gcc -Wbad-function-cast warning.
17270 Use a different way to cause a compilation error if anyone uses
17271 n rather than nn, a way that does not involve shadowing.
17272 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
17274 * deps.mk (unexalpha.o): Remove; unused.

17380 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
17381 to use the following functions instead of these macros.
17382 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
17383 EMACS_INT, since callers assume the returned value fits in int.
17384 (upcase1): Likewise, for UPCASE_TABLE.
17385 (uppercasep, lowercasep, upcase): New static inline functions.
17386 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
17387 the race-condition problem in the old DOWNCASE.
17389 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
17390 Rename locals to avoid shadowing.
17391 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
17392 (regex_compile, re_search_2, re_match_2_internal):
17393 Remove unused local vars.
17394 (FREE_VAR): Rewrite so as not to use empty "else",
17395 which gcc can warn about.
17396 (regex_compile, re_match_2_internal): Mark locals as initialized.
17397 (RETALLOC_IF): Define only if needed.
17398 (WORDCHAR_P): Likewise. This one is never needed, but is used
17399 only in a comment talking about a compiler bug, so put inside
17400 the #if 0 of that comment.
17401 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
17402 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
17405 * search.c (boyer_moore): Rename locals to avoid shadowing.
17406 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

17417 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
17419 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
17420 Rename locals to avoid shadowing.

17428 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
17429 New macros, so that the caller can use some names other than
17430 gcpro1, gcpro2, etc.
17431 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
17433 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
17434 argument, for consistency with GCPRO2_VAR, etc: it is now the
17435 prefix of the variable, not the variable itself. All uses
17437 * dired.c (directory_files_internal, file_name_completion):
17438 Rename locals to avoid shadowing.
17440 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
17441 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
17442 dired.c's scmp function, had undefined behavior.
17443 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17444 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
17445 * buffer.h: ... to here, because these macros use current_buffer,
17446 and the new implementation with inline functions needs to have
17447 current_buffer in scope now, rather than later when the macros
17449 (downcase, upcase1): New static inline functions.
17450 (DOWNCASE, UPCASE1): Reimplement using these functions.
17451 This avoids undefined behavior in expressions like
17452 DOWNCASE (x) == DOWNCASE (y), which previously suffered
17453 from race conditions in accessing the global variables
17454 case_temp1 and case_temp2.
17455 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
17456 * lisp.h (case_temp1, case_temp2): Remove their decls.
17457 * character.h (ASCII_CHAR_P): Move from here ...
17458 * lisp.h: ... to here, so that the inline functions mentioned
17459 above can use them.
17461 * dired.c (directory_files_internal_unwind): Now static.
17463 * fileio.c (file_name_as_directory, directory_file_name):
17464 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
17466 (file_name_as_directory): Use const pointers when appropriate.
17467 (Fexpand_file_name): Likewise. In particular, newdir might
17468 point at constant storage, so make it a const pointer.
17469 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
17470 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
17472 (Fset_file_times, Finsert_file_contents, auto_save_error):

17477 to avoid shadowing.
17479 * marker.c (bytepos_to_charpos): Remove; unused.
17481 * lisp.h (verify_bytepos, count_markers): New decls,
17482 so that gcc does not warn that these functions aren't declared.
17484 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
17485 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
17486 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
17487 (copy_text): Remove unused local var.
17489 * filelock.c (within_one_second): Now static.
17490 (lock_file_1): Rename local to avoid shadowing.
17492 * buffer.c (fix_overlays_before): Mark locals as initialized.
17493 (fix_start_end_in_overlays): Likewise. This function should be
17494 simplified by using pointers-to-pointers, but that's a different
17496 (switch_to_buffer_1): Now static.
17497 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
17498 (report_overlay_modification): Rename locals to avoid shadowing.
17500 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
17501 Fix pointer signedness issue.
17502 (sys_subshell): Mark local as volatile if checking for lint,
17503 to suppress a gcc -Wclobbered warning that does not seem to be right.
17504 (MAXPATHLEN): Define only if needed.
17506 * process.c (serial_open, serial_configure): Move decls from here ...
17507 * systty.h: ... to here, so that they can be checked.
17509 * fns.c (get_random, seed_random): Move extern decls from here ...
17510 * lisp.h: ... to here, so that they can be checked.
17512 * sysdep.c (reset_io): Now static.
17513 (wait_for_termination_signal): Remove; unused.
17515 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

17520 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
17521 (describe_map_tree):
17522 Rename locals to avoid shadowing.
17524 * keyboard.c: Declare functions static if they are not used elsewhere.
