21 * charset.c, charset.h (maybe_unify_char): Now static.
22 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
23 Since this stuff is now private to charset.c, there's no need for
24 a public macro and no need to inline by hand.

52 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
54 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
56 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
58 Prefer POSIX timers if available.
59 They avoid a race if the timer is too close to the current time.
60 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
61 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
62 (init_atimer) [SIGEV_SIGNAL]: Initialize them.

87 * w32.h (Vlibrary_cache): Do not declare.
89 2012-09-25 Eli Zaretskii <eliz@gnu.org>
91 * w32proc.c (sys_signal): Handle all signals defined by the
92 MS-Windows runtime, not just SIGCHLD. Actually install the signal
93 handlers for signals supported by Windows. Don't override
94 term_ntproc as the handler for SIGABRT.
95 (sigaction): Rewrite to call sys_signal instead of duplicating its
97 (sys_kill): Improve commentary.
99 * w32.c (term_ntproc): Accept (and ignore) one argument, for
100 consistency with a signature of a signal handler. All callers
102 (init_ntproc): Accept an argument DUMPING. If dumping, don't
103 install term_ntproc as a signal handler for SIGABRT, as that
104 should be done by the dumped Emacs.
106 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
108 * w32select.c (term_w32select): Protect against repeated
109 invocation by setting clipboard_owner to NULL after calling
112 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
113 and term_ntproc to their modified signatures.
115 * character.c (char_string, string_char): Remove calls to
116 MAYBE_UNIFY_CHAR. See the discussion starting at
117 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
120 2012-09-25 Chong Yidong <cyd@gnu.org>

127 when encountering an unknown bytecode.
129 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
131 image.c, indent.c: Use bool for booleans.
132 * dispextern.h (struct image_type): Members valid_p, load, init
133 now return bool, not int. All uses changed.
134 * image.c: Omit unnecessary static decls.
135 (x_create_bitmap_mask, x_build_heuristic_mask):
136 Return void, not int, since callers don't care about the return value.
137 (x_create_bitmap_mask, define_image_type, valid_image_p)

171 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
173 Move pid_t related decls out of lisp.h.
174 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
175 (interruptible_wait_for_termination):
176 Move these decls from lisp.h to syswait.h, since they use pid_t.
177 Needed on FreeBSD; see Herbert J. Skuhra in
178 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
179 * callproc.c: Include syswait.h.

199 Use bool for boolean.
200 * gtkutil.c (xg_update_frame_menubar):
201 * xmenu.c (update_frame_menubar):
202 Return void, not int, since caller ignores return value.

225 2012-09-23 Eli Zaretskii <eliz@gnu.org>
227 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
228 fatal_error_backtrace.
230 * w32proc.c (sys_kill): Undo last change: don't do anything when
231 invoked to deliver SIGABRT to our own process. This is now
232 handled by emacs_raise.
234 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
236 * w32term.c (w32_read_socket): Remove leftover reference to
237 interrupt_input_pending.
239 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
241 Do not use SA_NODEFER.
242 Problem reported by Dani Moncayo in
243 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
245 * sysdep.c (emacs_abort): Do not reset signal handler.
246 * emacs.c (terminate_due_to_signal): Reset signal handler here.
247 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
248 wanted even on POSIXish hosts, and it doesn't work on Windows.
250 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
252 * xterm.c (x_term_init): Call fixup_locale before and after calling
253 gtk_init (Bug#12392).
255 2012-09-23 Chong Yidong <cyd@gnu.org>
257 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
258 Vdynamic_library_alist.
260 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
261 (Fgnutls_available_p): Caller changed.
263 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
264 (Flibxml_parse_xml_region): Likewise.
266 * dispextern.h (struct image_type): Remove arg from init function.
268 * image.c (Finit_image_library, lookup_image_type)
269 (define_image_type): Remove now-unneeded second arg.
270 (init_xpm_functions, init_png_functions, init_jpeg_functions)
271 (init_tiff_functions, init_gif_functions, init_svg_functions):
272 Arglist and w32_delayed_load calling convention changed.
273 (gs_type): Remove init_gs_functions; there is no such function.
274 (valid_image_p, make_image): Fix caller to lookup_image_type.
276 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
278 Simplify and avoid signal-handling races (Bug#12471).
280 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
281 Avoid recursive loop if there's a fatal error in the function itself.
282 * atimer.c (pending_atimers):
283 * blockinput.h: Don't include "atimer.h"; no longer needed.
284 (interrupt_input_pending): Remove. All uses removed.
285 pending_signals now counts both atimers and ordinary interrupts.
286 This is less racy than having three separate pending-signal flags.
287 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
289 Rename from their upper-case counterparts BLOCK_INPUT,
290 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
291 INPUT_BLOCKED_P, and turn into functions. All uses changed.
292 This makes it easier to access volatile variables more accurately.
293 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
294 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
295 that's more reliable if the code is buggy and sets
296 interrupt_input_blocked to a negative value. All uses changed.
297 * atimer.c (deliver_alarm_signal):
298 Remove. No need to deliver this to the parent; any thread can
299 handle this signal now. All uses replaced by underlying handler.
300 * atimer.c (turn_on_atimers):
301 * dispnew.c (handle_window_change_signal):
302 * emacs.c (handle_danger_signal):
303 * keyboard.c (kbd_buffer_get_event):
304 Don't reestablish signal handler; not needed with sigaction.
305 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
307 Rework to avoid unnecessary accesses to volatile variables.
308 (UNBLOCK_INPUT_TO): Now a function.
309 (totally_unblock_input, unblock_input): New decls.
310 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
311 (init_data): Remove. Necessary stuff now done in init_signal.
312 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
313 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
314 (fatal_error_code): Remove; no longer needed.
315 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
316 it doesn't always backtrace. All uses changed. No need to reset
317 signal to default, since sigaction and/or die does that for us now.
318 Use emacs_raise (FOO), not kill (getpid (), FOO).
319 (main): Check more-accurately whether we're dumping.
320 Move fatal-error setup to sysdep.c
321 * floatfns.c: Do not include "syssignal.h"; no longer needed.
322 * gtkutil.c (xg_get_file_name, xg_get_font):
323 Remove no-longer-needed signal-mask manipulation.
324 * keyboard.c, process.c (POLL_FOR_INPUT):
325 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
326 * keyboard.c (read_avail_input): Remove.
327 All uses replaced by gobble_input.
328 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
329 (kbd_buffer_store_event_hold, gobble_input):
330 (record_asynch_buffer_change) [USABLE_SIGIO]:
331 (store_user_signal_events):
332 No need to mess with signal mask.
333 (gobble_input): If blocking input and there are terminals, simply
334 set pending_signals to 1 and return. All hooks changed to not
335 worry about whether input is blocked.
336 (process_pending_signals): Clear pending_signals before processing
337 them, in case a signal comes in while we're processing.
338 By convention callers now test pending_signals before calling us.
339 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
340 New functions, to support changes to blockinput.h.
341 (handle_input_available_signal): Now extern.
342 (reinvoke_input_signal): Remove. All uses replaced by
344 (quit_count): Now volatile, since a signal handler uses it.
345 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
346 All callers changed. Block SIGINT only if not already blocked.
347 Clear sigmask reliably, even if Fsignal returns, which it can.
348 Omit unnecessary accesses to volatile var.
349 (quit_throw_to_read_char): No need to restore sigmask.
350 * keyboard.c (gobble_input, handle_user_signal):
351 * process.c (wait_reading_process_output):
352 Call signal-handling code rather than killing ourselves.
353 * lisp.h: Include <float.h>, for...
354 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
355 (pending_signals): Now volatile.
356 (syms_of_data): Now const if IEEE floating point.
357 (handle_input_available_signal) [USABLE_SIGIO]:
358 (terminate_due_to_signal, record_child_status_change): New decls.
359 * process.c (create_process): Avoid disaster if memory is exhausted
360 while we're processing a vfork, by tightening the critical section
362 (send_process_frame, process_sent_to, handle_pipe_signal)
363 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
365 (send_process): No need for setjmp/longjmp any more, since the
366 SIGPIPE stuff is now gone. Instead, report an error if errno
368 (record_child_status_change): Now extern. PID and W are now args.
369 Return void, not bool. All callers changed.
370 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
371 Remove. All uses removed. This bug should be fixed now in a
373 (wait_for_termination_1): Use waitpid rather than sigsuspend,
374 and record the child status change directly. This avoids the
375 need to futz with the signal mask.
376 (process_fatal_action): Move here from emacs.c.
377 (emacs_sigaction_flags): New function, containing
378 much of what used to be in emacs_sigaction_init.
379 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
380 caught by emacs, to make races less likely.
381 (deliver_process_signal): Rename from handle_on_main_thread.
383 (BACKTRACE_LIMIT_MAX): Now at top level.
384 (thread_backtrace_buffer, threadback_backtrace_pointers):
386 (deliver_thread_signal, deliver_fatal_thread_signal):
387 New functions, for more-accurate delivery of thread-specific signals.
388 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
389 (deliver_arith_signal): Handle in this thread, not
390 in the main thread, since it's triggered by this thread.
391 (maybe_fatal_sig): New function.
392 (init_signals): New arg DUMPING so that we can be more accurate
393 about whether we're dumping. Caller changed.
394 Treat thread-specific signals differently from process-general signals.
395 Block all signals while handling fatal error; that's safer.
396 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
398 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
399 Ignore SIGPIPE unless batch.
400 (emacs_backtrace): Output backtrace for the appropriate thread,
401 which is not necessarily the main thread.
402 * syssignal.h: Include <stdbool.h>.
403 (emacs_raise): New macro.
404 * xterm.c (x_connection_signal): Remove; no longer needed
405 now that we use sigaction.
406 (x_connection_closed): No need to mess with sigmask now.
407 (x_initialize): No need to reset SIGPIPE handler here, since
408 init_signals does this for us now.
410 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
412 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
413 background rect may be larger (Bug#12245).
415 2012-09-23 Chong Yidong <cyd@gnu.org>
417 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
419 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
421 * .gdbinit: Just stop at fatal_error_backtrace.
422 See Stefan Monnier's request in
423 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
424 Remove no-longer-used query of system type.
426 2012-09-22 Chong Yidong <cyd@gnu.org>
428 * search.c (Freplace_match): Doc fix (Bug#12325).
430 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
432 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
433 (Fline_end_position): Doc fix.
435 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
437 2012-09-22 Chong Yidong <cyd@gnu.org>
439 * dispextern.h (struct image_type): Add new slot, storing a type
440 initialization function.
442 * image.c (define_image_type): Call the image initializer function
443 if it is defined. Arguments and return value changed.
444 (valid_image_p, make_image): Callers changed.
445 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
446 (gif_type, imagemagick_type, svg_type, gs_type):
447 Add initialization functions.
448 (Finit_image_library): Call lookup_image_type.
449 (CHECK_LIB_AVAILABLE): Macro deleted.
450 (lookup_image_type): Call define_image_type here, rather than via
451 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
452 (syms_of_image): Move define_image_type calls for xbm_type and
453 pbm_type to lookup_image_type.
455 2012-09-22 Eli Zaretskii <eliz@gnu.org>
457 * keyboard.c (timer_check_2): Move calculation of 'timers' and
458 'idle_timers' from here ...
459 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
460 lists, to avoid infloops when the timer does something stupid,
461 like reinvoke itself with the same or smaller time-out.
464 2012-09-22 Martin Rudalics <rudalics@gmx.at>
466 * window.c (Fsplit_window_internal): Handle only Qt value of
467 Vwindow_combination_limit separately.
468 (Qtemp_buffer_resize): New symbol.
469 (Vwindow_combination_limit): New default value.
472 2012-09-22 Eli Zaretskii <eliz@gnu.org>
474 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
475 the new overlay string. (Bug#10159)
477 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
479 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
480 or that fprintf is async-signal-safe. POSIX doesn't require
483 2012-09-22 Chong Yidong <cyd@gnu.org>
485 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
488 2012-09-22 Kenichi Handa <handa@gnu.org>
490 * composite.c (composition_reseat_it): Handle the case that a
491 grapheme cluster is not covered by a single font (Bug#12352).
493 2012-09-21 Chong Yidong <cyd@gnu.org>
495 * image.c (define_image_type): Avoid adding duplicate types to
496 image_types (Bug#12463). Suggested by Jörg Walter.
498 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
500 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
501 (print_load_command_name): Add case LC_DATA_IN_CODE.
502 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
504 2012-09-21 Glenn Morris <rgm@gnu.org>
506 * eval.c (Frun_hook_with_args_until_success)
507 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
509 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
511 * fileio.c (Ffile_selinux_context): Only call freecon when
512 lgetfilecon succeeded.
513 (Fset_file_selinux_context): Likewise. (Bug#12444)
515 2012-09-21 Eli Zaretskii <eliz@gnu.org>
517 * xdisp.c (try_window_reusing_current_matrix): Under bidi
518 reordering, locate the cursor by calling set_cursor_from_row; if
519 that fails, clear the desired glyph matrix before returning a
520 failure indication to the caller. Fixes leaving garbled display
521 when fast scrolling with a down-key. (Bug#12403)
522 (compute_stop_pos_backwards): Fix a typo that caused crashes while
523 scrolling through multibyte text.
525 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
527 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
528 calling mark_vectorlike since that's the one that marks the window.
529 (mark_discard_killed_buffers): Mark the final cdr.
530 * window.h (struct window): Move prev/next_buffers to the
532 * window.c (make_window): Initialize prev/next_buffers manually.
534 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
536 Omit unused arg EXPECTED from socket hooks.
537 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
538 * nsterm.m (ns_term_init):
539 * termhooks.h (struct terminal.read_socket_hook):
540 * w32inevt.c (w32_console_read_socket):
541 * w32term.c (w32_read_socket):
542 * xterm.c (XTread_socket):
543 Omit unused arg EXPECTED. All callers changed.
544 (store_user_signal_events): Return void, not int, since callers no
545 longer care about the return value. All uses changed.
547 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
549 * w32gui.h (XParseGeometry): Do not declare.
551 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
553 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
554 Ignore 'expected'. See Eli Zaretskii in
555 <http://bugs.gnu.org/12471#8> (last line).
557 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
558 (XParseGeometry): Now static. Substitute extremal values for
559 values that are out of range.
561 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
563 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
565 * nsfns.m (XParseGeometry): Remove.
566 (Fx_create_frame): Call x_set_offset to correctly interpret
569 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
570 (Fx_parse_geometry): If there is a space in string, call
571 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
573 2012-09-17 Eli Zaretskii <eliz@gnu.org>
575 * search.c (scan_buffer): Use character positions in calls to
576 region_cache_forward and region_cache_backward, not byte
577 positions. (Bug#12196)
579 * w32term.c (w32_read_socket): Set pending_signals to 1, like
580 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
582 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
583 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
584 emacs_blocked_malloc, now deleted.
586 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
588 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
589 The workaround was for improving performance on Solaris 2.4, but
590 is getting in the way now. Emacs will still work if someone is
591 still running Solaris 2.4 in a museum somewhere; Sun dropped
592 support for Solaris 2.4 in 2003.
593 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
594 * process.c (create_process) [HAVE_WORKING_VFORK]:
595 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
596 since Emacs no longer uses vfork on that platform.
598 2012-09-17 Glenn Morris <rgm@gnu.org>
600 * emacs.c: Use COPYRIGHT.
602 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
604 Remove configure's --without-sync-input option (Bug#12450).
605 When auditing signal-handling in preparation for cleaning it up,
606 I found that SYNC_INPUT has race conditions and would be a real
607 pain to fix. Since it's an undocumented and deprecated
608 configure-time option, now seems like a good time to remove it.
609 Also see <http://bugs.gnu.org/11080#16>.
610 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
611 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
612 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
614 (check_depth) [XMALLOC_OVERRUN_CHECK]:
615 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
616 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
617 (dont_register_blocks, bytes_used_when_reconsidered)
618 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
619 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
620 [!SYSTEM_MALLOC && !SYNC_INPUT]:
621 Remove. All uses removed.
622 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
623 implementation, one that depends on whether the new macro
624 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
626 * atimer.c (run_timers, handle_alarm_signal):
627 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
628 (handle_async_input, process_pending_signals)
629 (handle_input_available_signal, init_keyboard):
630 * nsterm.m (ns_read_socket):
631 * process.c (wait_reading_process_output):
632 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
633 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
635 * xterm.c (XTread_socket):
637 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
638 * eval.c (handling_signal): Remove. All uses removed.
639 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
640 All uses replaced with the SYNC_INPUT version.
641 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
643 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
646 * font.c (Ffont_shape_gstring): Remove unused local.
648 2012-09-16 Glenn Morris <rgm@gnu.org>
650 * Makefile.in (clean): No longer run nextstep's clean.
652 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
654 (ns-app): Move here from ns.mk, and simplify.
655 (clean): Simplify nextstep entry.
656 * ns.mk: Remove file.
658 2012-09-17 Kenichi Handa <handa@gnu.org>
660 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
661 not covert the last few charactes.
663 2012-09-16 Kenichi Handa <handa@gnu.org>
665 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
666 here, but just check the validity of glyphs in the glyph-string.
668 2012-09-16 Martin Rudalics <rudalics@gmx.at>
670 * window.c (Fwindow_parameter, Fset_window_parameter):
671 Accept any window as argument (Bug#12452).
673 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
675 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
676 to ns_term_init to avoid memory leak.
678 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
679 explicit retain/release.
680 (ns_term_init): Only allow one display. Initialize outerpool and
683 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
685 Port _setjmp fix to POSIXish hosts as well as Microsoft.
686 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
687 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
688 the Microsoft problem in a different way, by altering ../nt/config.nt.
690 2012-09-15 Eli Zaretskii <eliz@gnu.org>
705 * w16select.c: Remove inclusion of setjmp.h, as it is now included
706 by lisp.h. This completes removal of setjmp.h inclusion
707 erroneously announced in the previous commit. (Bug#12446)
709 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
712 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
713 not defined as a macro. The latter happens on MS-Windows.
716 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
718 Port better to POSIX hosts lacking _setjmp (Bug#12446).
719 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
720 Some instances of '#include <setjmp.h>' removed, if the
721 only reason for the instance was because "lisp.h" was included.
722 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
723 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
724 and _longjmp with the new symbols. Emacs already uses _setjmp if
725 available, so this change affects only POSIXish hosts that have
726 sigsetjmp but not _setjmp, such as some versions of Solaris and
727 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
728 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
729 (png_load_body) [HAVE_PNG]:
730 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
731 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
732 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
733 since PNG requires jmp_buf. This is the only exception to the
734 general rule that we now use sys_setjmp and sys_longjmp.
735 This exception is OK since this code does not change the signal
736 mask or longjmp out of a signal handler.
738 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
740 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
741 Include "syssignal.h", for 'main_thread'.
743 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
745 Avoid out-of-range marker position (Bug#12426).
746 * insdel.c (replace_range, replace_range_2):
747 Adjust markers before overlays, as suggested by comments.
748 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
749 Remove redundant check before calling offset_intervals.
751 2012-09-14 Martin Rudalics <rudalics@gmx.at>
753 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
754 current buffer (Bug#12387).
756 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
758 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
760 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
762 Use a more backwards-compatible timer format (Bug#12430).
763 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
764 vector element, not from the 4th, since PSECS is now at the end.
765 (Fcurrent_idle_time): Doc fix.
767 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
769 Function to mark objects and remove killed buffers at once.
770 * alloc.c (discard_killed_buffers): Rename to ...
771 (mark_discard_killed buffers) ... new name. Add marking
772 of remaining objects. Fix comment. Adjust users.
773 (mark_object): Do not touch frame buffer lists here.
774 * frame.c (delete_frame): Reset frame buffer lists here.
776 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
778 Better workaround for GNOME bug when --enable-gcc-warnings.
779 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
780 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
781 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
783 Simplify SIGIO usage (Bug#12408).
784 The code that dealt with SIGIO was crufty and confusing, e.g., it
785 played tricks like "#undef SIGIO" but these tricks were not used
786 consistently. Simplify mostly by not #undeffing standard symbols,
787 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
788 or not as we please) rather than "defined SIGIO" (standard symbol
789 that we probably shouldn't #undef).
790 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
791 Modules that need it can include it.
792 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
793 * dispextern.h (ignore_sigio): New decl.
794 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
795 unconditionally, since it's now a no-op if !USABLE_SIGIO.
796 * emacs.c (shut_down_emacs):
797 * keyboard.c (kbd_buffer_store_event_hold):
798 Use ignore_sigio rather than invoking 'signal' directly.
799 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
801 (FIONREAD, SIGIO): Do not #undef.
802 (tty_read_avail_input): Use #error rather than a syntax error.
803 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
804 for I_PIPE, used by SETUP_SLAVE_PTY.
805 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
806 * sysdep.c (croak): Remove; no longer needed. This bit of
807 temporary code, with Fred N. Fish's comment that it's temporary,
808 has been in Emacs since at least 1992!
809 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
810 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
811 * syssignal.h (croak): Remove decl.
812 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
813 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
814 now that we're termios-only.
815 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
816 * term.c (dissociate_if_controlling_tty): Use #error rather than
819 Work around GCC and GNOME bugs when --enable-gcc-warnings.
820 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
821 to work around GNOME bug 683906.
822 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
823 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
824 This works around GCC bug 54561.
826 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
828 More fixes for 'volatile' and setjmp/longjmp.
829 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
830 * image.c (struct png_load_context) [HAVE_PNG]: New type.
831 (png_load_body) [HAVE_PNG]:
832 (jpeg_load_body) [HAVE_JPEG]:
833 New function, with most of the old parent function's body.
834 (png_load) [HAVE_PNG]:
835 (jpeg_load) [HAVE_JPEG]:
836 Invoke the new function, to avoid longjmp munging our locals.
837 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
838 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
839 longjmp is passed 2, as the C standard doesn't guarantee this.
840 Instead, store the failure code into mgr->failure_code.
842 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
844 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
845 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
846 (syms_of_keyboard): Remove support for unread-command-char.
848 2012-09-12 Eli Zaretskii <eliz@gnu.org>
850 * w32proc.c (sys_kill): If PID is our process ID and the signal is
851 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
852 violation. (Bug#12426)
854 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
856 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
858 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
860 * eval.c: Add `inhibit-debugger'.
861 (Qinhibit_debugger): New symbol.
862 (call_debugger): Bind it instead of Qdebug_on_error.
863 (maybe_call_debugger): Test Vinhibit_debugger.
864 (syms_of_eval): Define inhibit-debugger.
865 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
866 (syms_of_xdisp): Remove inhibit-debug-on-message.
868 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
870 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
871 If a nonvolatile local variable is written before a _longjmp to
872 the frame containing the variable, and is read after the _longjmp,
873 the value read is indeterminate. Some local variables of type
874 'struct handler' and 'struct catchtag' are used in this way, so
875 mark each of their slots as volatile if the slot can be set before
876 _longjmp and read afterwards.
877 * lisp.h (struct handler): var and chosen_clause are now volatile.
878 (struct catchtag): val, next, and pdlcount are now volatile.
880 * bidi.c (bidi_push_it, bidi_pop_it):
881 * fns.c (copy_hash_table):
882 * image.c (define_image_type):
883 * keyboard.c (kbd_buffer_store_event_hold):
884 * process.c (Fprocess_send_eof):
885 * xfaces.c (x_create_gc) [HAVE_NS]:
886 * xgselect.c (xg_select):
887 Prefer assignment to memcpy when either will do.
889 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
890 Use pointer-to-a-pointer to simplify and avoid a NILP check each
891 time an item is removed. No need to mark this function 'inline';
892 the compiler knows better than we do.
894 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
896 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
897 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
898 to change_frame_size (Bug#12388).
899 (windowDidResize:): Pass YES to updateFrameSize.
901 * nsterm.h: Add delay parameter to updateFrameSize.
903 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
905 Discard killed buffers from deleted window and frame objects.
906 This reduces an amount of references to killed buffers and
907 helps GC to reclaim them faster.
908 * alloc.c (discard_killed_buffers): New function.
909 (mark_object): Use it for deleted windows and frames.
910 (mark_object): If symbol's value is set up for a killed buffer
911 or deleted frame, restore it's global binding.
912 * data.c (swap_in_global_binding): Add GC notice.
913 (swap_in_symval_forwarding): Use convenient set_blv_where.
914 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
915 * window.h: ... to here.
917 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
919 Convenient macro to check whether the buffer is live.
920 * buffer.h (BUFFER_LIVE_P): New macro.
921 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
922 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
924 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
926 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
927 composition cases (Bug#12364).
929 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
930 overhang of succeeding glyphs overlapping box cursor.
932 * w32term.c (x_draw_glyph_string): Likewise.
934 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
936 Simplify, document, and port floating-point (Bug#12381).
937 The porting part of this patch fixes bugs on non-IEEE platforms
938 with frexp, ldexp, logb.
939 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
941 * floatfns.c: Simplify discussion of functions that Emacs doesn't
942 support, by removing commented-out code and briefly listing the
943 C89 functions excluded. The commented-out stuff was confusing
944 maintenance, e.g., we thought we needed cbrt but it was commented out.
945 (logb): Remove decl; no longer needed.
946 (isfinite): New macro, if not already supplied.
947 (isnan): Don't replace any existing macro.
948 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
949 are present on all C89 platforms.
950 (Ffrexp): Do not special-case zero, as frexp does the right thing
952 (Flogb): Do not use logb, as it doesn't have the desired meaning
953 on hosts that use non-base-2 floating point. Instead, stick with
954 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
955 frexp, to avoid getting an unspecified result.
957 * xdisp.c (Qinhibit_debug_on_message): Now static.
959 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
961 * nsterm.m (ns_update_begin): Set clip path to whole view by using
962 NSBezierPath (Bug#12131).
964 2012-09-10 Chong Yidong <cyd@gnu.org>
966 * fns.c (Fdelq, Fdelete): Doc fix.
968 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
970 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
971 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
973 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
975 * lisp.h (make_lisp_ptr): New macro to replace XSET.
976 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
979 2012-09-09 Eli Zaretskii <eliz@gnu.org>
981 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
982 left fringe if the window has a left margin. This avoids leaving
983 traces of the cursor because its leftmost pixel is not drawn over.
985 * dispnew.c (update_window_line): When the left margin area of a
986 screen line is updated, set the redraw_fringe_bitmaps_p flag of
987 that screen line. (Bug#12277)
989 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
991 Assume C89 or later for math functions (Bug#12381).
992 This simplifies the code, and makes it a bit smaller and faster,
993 and (most important) makes it easier to clean up signal handling
994 since we can stop worring about floating-point exceptions in
995 library code. That was a problem before C89, but the problem
996 went away many years ago on all practical Emacs targets.
997 * data.c, image.c, lread.c, print.c:
998 Don't include <math.h>; no longer needed.
999 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
1000 might be autoconfigured, as that never happens.
1002 * doprnt.c (DBL_MAX_10_EXP):
1003 * print.c (DBL_DIG):
1004 Remove. C89 or later always defines these.
1005 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
1006 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
1007 (arith_error, domain_error, domain_error2):
1008 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
1009 no longer needed -- we simply return what C returns. All uses removed.
1010 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
1012 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
1013 Remove. All uses expanded, as these macros are no longer used
1014 more than once and are now more trouble than they're worth.
1015 (Ftan): Use tan, not sin / cos.
1016 (Flogb): Assume C89 frexp.
1017 (fmod_float): Assume C89 fmod.
1018 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
1019 (init_floatfns): Remove. All uses removed.
1021 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1023 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
1024 compositeToPoint for OSX < 10.6 (Bug#12390).
1026 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
1028 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
1029 This produces more-accurate results.
1031 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1033 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
1034 changes (Bug#12088).
1036 2012-09-08 Chong Yidong <cyd@gnu.org>
1038 * syntax.c (Fstring_to_syntax): Doc fix.
1040 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1042 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
1043 in the internal border.
1044 (x_set_window_size): Remove static variables and their usage.
1045 (ns_redraw_scroll_bars): Fix NSTRACE arg.
1046 (ns_after_update_window_line, ns_draw_fringe_bitmap):
1047 Remove fringe/internal border adjustment (Bug#11052).
1048 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
1049 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
1050 (ns_fix_rect_ibw): Remove.
1051 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
1052 (ns_dumpglyphs_box_or_relief): Ditto.
1053 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
1055 (ns_dumpglyphs_image): Ditto.
1056 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
1058 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
1059 their usage. Add fringe_extended_p and its use as in other terms.
1060 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
1061 scroll bar was removed.
1062 (updateFrameSize): New function.
1063 (windowDidResize): Move code to updateFrameSize and call it.
1065 * nsterm.h (EmacsView): Add updateFrameSize.
1067 2012-09-07 Chong Yidong <cyd@gnu.org>
1069 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
1071 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
1073 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1075 More signal-handler cleanup (Bug#12327).
1076 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
1077 Problem introduced when merging patches. Noted by Eli Zaretskii in
1078 <http://bugs.gnu.org/12327#67>.
1079 * floatfns.c: Comment fix.
1080 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
1081 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
1082 and anyway the declaration is harmless even if SIGDANGER is not defined.
1083 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
1084 defined BROKEN_FIONREAD). systty.h formerly did this, but other
1085 source files not surprisingly expected syssignal.h to define, or
1086 not define, SIGIO, and it's cleaner to do it that way, for consistency.
1087 Include <sys/ioctl.h>, for FIONREAD.
1088 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
1089 This eliminates a problem whereby other files mysteriously had
1090 to include "syssignal.h" before including "systty.h" if they
1091 wanted to use "#ifdef SIGIO".
1093 2012-09-07 Eli Zaretskii <eliz@gnu.org>
1095 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
1097 * w32.c (sigemptyset): Empty the set.
1098 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
1100 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
1102 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
1104 * alloc.c (mark_buffer): Revert unsafe marking optimization.
1105 (mark_object): Likewise for frame objects.
1107 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1109 * syssignal.h (handle_on_main_thread): Always declare,
1110 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
1111 This ports to platforms without HAVE_PTHREAD.
1113 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1115 Signal-handler cleanup (Bug#12327).
1116 Emacs's signal handlers were written in the old 4.2BSD style with
1117 sigblock and sigmask and so forth, and this led to some
1118 inefficiencies and confusion. Rewrite these to use
1119 pthread_sigmask etc. without copying signal sets around. Also,
1120 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
1121 'signal', and instead use functions that do not attempt to take
1122 over the system name space. This patch causes Emacs's text
1123 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
1124 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
1125 Do not include <signal.h> or "syssignal.h", as these
1126 modules do not use signals.
1127 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
1128 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
1129 Do not include <signal.h>, as "syssignal.h" does that for us now.
1130 * atimer.c (sigmask_atimers): New function.
1131 (block_atimers, unblock_atimers): New functions,
1132 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
1134 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
1135 no longer needed here.
1136 * emacs.c (main): Inspect existing signal handler with sigaction,
1137 so that there's no need to block and unblock SIGHUP.
1138 * sysdep.c (struct save_signal): New member 'action', replacing
1139 old member 'handler'.
1140 (save_signal_handlers, restore_signal_handlers):
1141 Use sigaction instead of 'signal' to save and restore.
1142 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
1143 New function. All users of 'signal' modified to use set_sighandler
1144 if they're writeonly, and to use sys_signal if they're read+write.
1145 (emacs_sigaction_init, forwarded_signal): New functions.
1146 (sys_signal): Remove. All uses replaced by calls to sigaction
1147 and emacs_sigaction_init, or by direct calls to 'signal'.
1148 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
1149 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
1150 all uses replaced by pthread_sigmask etc. calls.
1151 * syssignal.h: Include <signal.h>.
1152 (emacs_sigaction_init, forwarded_signal): New decls.
1153 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
1154 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
1155 (sigmask, sys_sigmask): Remove; no longer needed.
1156 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
1157 (sigblock, sigunblock, sigfree):
1158 (sigsetmask) [!defined sigsetmask]:
1159 Remove. All uses replaced by pthread_sigmask.
1160 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
1161 no longer need to be replaced, and its typical old uses
1162 are now done via emacs_sigaction_init and sigaction.
1163 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
1164 (sys_sigdel): Remove; unused.
1165 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
1167 2012-09-06 Eli Zaretskii <eliz@gnu.org>
1169 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
1170 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
1172 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1174 Explicitly mark buffer_defaults and buffer_local_symbols.
1175 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
1176 mark_local_symbols here.
1177 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
1178 since special buffers aren't marked here any more.
1179 (allocate_buffer): Chain new buffer with all_buffers here...
1180 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
1182 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
1183 (syms_of_buffer): Remove staticpro of the above.
1184 (init_buffer_once): Set names for buffer_defaults and
1185 buffer_local_symbols.
1187 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1189 Use bool for booleans in font-related modules.
1190 * font.c (font_intern_prop, font_style_to_value)
1191 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
1192 (generate_otf_features, font_check_otf_features, font_check_otf)
1193 (font_match_p, font_list_entities, font_at):
1194 * fontset.c (fontset_id_valid_p, reorder_font_vector
1195 (fontset_find_font, Fset_fontset_font)
1196 (face_suitable_for_char_p) [0]:
1197 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
1198 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
1199 (m17n_flt_initialized, ftfont_shape_by_flt):
1200 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
1201 * nsfont.m (nsfont_draw):
1202 * w32font.c (w32font_draw):
1203 * w32term.c (x_draw_glyphless_glyph_string_foreground):
1204 Use bool for booleans.
1205 * font.h: Adjust to above API changes.
1206 (struct font, struct font_driver, struct font_driver_list):
1207 Use bool for booleans.
1208 (struct font): Remove useless member encoding_type.
1210 * fontset.c, xftfont.c: Omit unnecessary static decls.
1212 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1214 * alloc.c (mark_object): Revert window marking code
1215 since it's unsafe for the Fset_window_configuration.
1217 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1219 Fix race conditions with signal handlers and errno (Bug#12327).
1220 Be more systematic about preserving errno whenever a signal
1221 handler returns, even if it's not in the main thread. Do this by
1222 renaming signal handlers to distinguish between signal delivery
1223 and signal handling. All uses changed.
1224 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
1225 * data.c (deliver_arith_signal): Rename from arith_error.
1226 * dispnew.c (deliver_window_change_signal): Rename from
1227 window_change_signal.
1228 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
1229 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
1230 * keyboard.c (deliver_input_available_signal): Rename from
1231 input_available_signal.
1232 (deliver_user_signal): Rename from handle_user_signal.
1233 (deliver_interrupt_signal): Rename from interrupt_signal.
1234 * process.c (deliver_pipe_signal): Rename from send_process_trap.
1235 (deliver_child_signal): Rename from sigchld_handler.
1236 * atimer.c (handle_alarm_signal):
1237 * data.c (handle_arith_signal):
1238 * dispnew.c (handle_window_change_signal):
1239 * emacs.c (handle_fatal_signal, handle_danger_signal):
1240 * keyboard.c (handle_input_available_signal):
1241 * keyboard.c (handle_user_signal, handle_interrupt_signal):
1242 * process.c (handle_pipe_signal, handle_child_signal):
1243 New functions, with the actual signal-handling code taken from the
1244 original respective signal handlers, sans the sporadic attempts to
1245 preserve errno, since that's now done by handle_on_main_thread.
1246 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
1247 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
1248 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1250 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1251 Move initialization of main_thread to sysdep.c's init_signals.
1252 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
1253 our usage, and simplifies the mainline code.
1254 (record_child_status_change): New static function, as a helper
1255 for handle_child_signal, and with most of the old child handler's
1257 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
1258 (handle_child_signal): Use the above.
1259 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1260 Moved here from emacs.c.
1261 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
1262 code moved here from emacs.c's main function.
1263 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
1264 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
1265 This lets callers save and restore errno properly.
1267 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1269 Remove redundant or unused things here and there.
1270 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
1271 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
1272 * editfns.c (Fcompare_buffer_substrings): Likewise.
1273 * frame.h (struct terminal, struct font_driver_list):
1274 Remove redundant declarations.
1275 * window.h (Qleft, Qright): Likewise.
1277 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1279 Do not mark objects from deleted buffers, windows and frames.
1280 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
1281 (mark_object): Likewise for windows and frames.
1283 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1285 * alloc.c (valid_lisp_object_p): Treat killed buffers,
1286 buffer_defaults and buffer_local_symbols as valid objects.
1287 Return special value to denote them.
1289 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1291 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
1292 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
1293 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
1294 (file_name_absolute_p, Fsubstitute_in_file_name):
1295 (check_executable, check_writable, Ffile_accessible_directory_p)
1296 (Fset_file_selinux_context, Fdefault_file_modes)
1297 (Finsert_file_contents, choose_write_coding_system)
1298 (Fwrite_region, build_annotations, a_write, e_write)
1300 * filelock.c (boot_time_initialized, get_boot_time)
1301 (get_boot_time_1, lock_file_1, within_one_second):
1302 * floatfns.c (in_float):
1303 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
1304 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
1305 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
1306 * lisp.h (struct Lisp_Hash_Table.cmpfn):
1307 * window.c (compare_window_configurations):
1308 Use bool for booleans.
1309 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
1310 (Fdefault_file_modes): Now mode_t, not int, for modes.
1311 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
1312 (internal_delete_file): Now returns void, not a (boolean) int,
1313 since nobody was looking at the return value.
1314 * lisp.h, window.h: Adjust to above API changes.
1316 * xdisp.c (set_message): Simplify and reindent last change.
1318 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
1320 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
1322 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
1324 * eval.c (call_debugger): Make the function non-static so that we
1325 can call it from set_message.
1327 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
1328 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
1330 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1332 Give more-useful info on a fatal error (Bug#12328).
1333 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
1334 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
1335 of doing the work ourselves.
1336 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
1337 do most of the work.
1338 (fatal_error_backtrace): New function, taken from the guts
1339 of the old fatal_error_signal, but with a new option to output
1341 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
1342 info about the signal than just its number.
1343 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
1344 * sysdep.c: Include <execinfo.h>
1345 (emacs_backtrace): New function, taken partly from the previous
1346 code of the 'die' function.
1347 (emacs_abort): Call fatal_error_backtrace rather than abort.
1349 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
1351 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
1352 eager (load-time) macro-expansion.
1353 * lisp.mk (lisp): Add macroexp.
1355 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1357 Simplify redefinition of 'abort' (Bug#12316).
1358 Do not try to redefine the 'abort' function. Instead, redo
1359 the code so that it calls 'emacs_abort' rather than 'abort'.
1360 This removes the need for the NO_ABORT configure-time macro
1361 and makes it easier to change the abort code to do a backtrace.
1362 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
1363 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
1364 Remove; sysdep.c's emacs_abort now takes its place.
1365 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
1366 'abort' changed to use 'emacs_abort'.
1367 * msdos.c (dos_abort) [defined abort]: Remove; not used.
1368 (abort) [!defined abort]: Rename to ...
1369 (emacs_abort): ... new name.
1370 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
1371 the place of the old 'abort' in emacs.c.
1372 * w32.c, w32fns.c (abort): Do not #undef.
1373 * w32.c (emacs_abort): Rename from w32_abort.
1375 2012-09-04 Eli Zaretskii <eliz@gnu.org>
1377 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
1378 offsets[j].dv, since the y axis of the screen coordinates points
1379 down, while the y axis of the font definition coordinates points
1380 up. This fixes display of Arabic diacritics such as KASRA and
1381 KASRATAN. (Bug#11860)
1383 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>

1386 * alloc.c (test_setjmp, mark_stack):
1387 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
1388 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
1389 (png_load, my_error_exit, jpeg_load):
1390 * process.c (send_process_trap, send_process):
1391 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
1392 The underscored versions are up to 30x faster on some hosts.
1393 Formerly, the code used setjmp+longjmp sometimes and
1394 _setjmp+_longjmp at other times, with no particular reason to
1395 prefer setjmp+longjmp.
1397 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
1399 Fix minor problem found by static checking.

1428 * firstfile.c (dummy): Use the address of 'main', whose signature
1429 won't change, instead of the address of 'initialize', whose
1430 signature just changed from int to bool.
1431 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
1432 * msdos.c (fatal_error_in_progress): ... from here.
1433 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
1435 (redisplay_internal, unwind_redisplay): Simply clear
1436 REDISPLAYING_P when unwinding, instead of saving its previous,
1437 always-false value and then restoring it.
1439 Clean up some extern decls.
1440 Mostly, this hoists extern decls out of .c files and into .h files.
1441 That way, we're more likely to catch errors if the interfaces change.
1442 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
1443 declare xg_mark_data.
1444 * dispextern.h (x_frame_parm_handlers):

1464 Remove now-redundant extern decls.
1465 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
1466 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
1468 * xfaces.c: Remove unnecessary static decls.
1469 * xterm.c (updating_frame): Remove decl of nonexistent object.
1471 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
1472 when building globals.h, as the objects that are not built on
1473 this host are not needed to compile C files on this host.
1475 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
1477 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

1525 2012-09-01 Eli Zaretskii <eliz@gnu.org>
1527 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
1528 more than one grapheme cluster passed to the shaper: compute the
1529 offset adjustment values separately for each cluster. (Bug#11860)
1531 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1532 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1533 about implicit conversions from integer to pointer.
1535 2012-09-01 Daniel Colascione <dancol@dancol.org>
1537 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
1538 system used too early.

1591 window system declarations.
1593 * frame.h: Move common functions here: set_frame_menubar,
1594 x_set_window_size, x_sync, x_get_focus_frame,
1595 x_set_mouse_position, x_set_mouse_pixel_position,
1596 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

1623 * lisp.h (mark_ttys): Remove prototype.
1624 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call

1680 Handle click on close button as quit.
1682 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
1683 Add window_closed and button_values. Add void as return value for
1684 add(Button|String|Split). addButton takes int instead of Lisp_Object.
1685 Add process_dialog as new member.
1687 2012-08-28 Eli Zaretskii <eliz@gnu.org>
1689 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

1820 (Fset_coding_system_priority):
1821 * fileio.c (Finsert_file_contents):
1822 Use bool for booleans.
1823 * coding.h, lisp.h: Reflect above API changes.
1824 * coding.c: Remove unnecessary static function decls.
1825 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
1826 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
1827 not a boolean 'int', since callers never look at the return value.
1828 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
1829 * coding.h (decoding_buffer_size, encoding_buffer_size)
1830 (emacs_mule_string_char): Remove unused extern decls.
1831 (struct iso_2022_spec, struct coding_system):
1832 Use 'unsigned int : 1' for boolean fields, since there's more than one.
1833 (struct emacs_mule_spec): Remove unused field 'full_support'.
1834 All initializations removed.
1835 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
1837 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
1839 Fix spare memory change (Bug#12286).
1840 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
1841 (valid_lisp_object_p): Likewise.
1843 2012-08-27 Martin Rudalics <rudalics@gmx.at>
1845 * window.c (Fset_window_configuration): Record any window's old
1846 buffer if it's replaced (see Bug#8789). If the new current
1847 buffer doesn't appear in the selected window, go to its old
1850 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
1852 Special MEM_TYPE_SPARE to denote reserved memory.
1853 * alloc.c (enum mem_type): New memory type.
1854 (refill_memory_reserve): Use new type for spare memory.
1855 This prevents live_cons_p and live_string_p from incorrect
1856 detection of uninitialized objects from spare memory as live.
1858 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
1861 * Makefile.in (.PHONY): versioclean -> versionclean.
1863 Remove unused external symbols.
1864 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
1865 * window.c (Qwindow_valid_p, decode_valid_window):
1866 Now static, not extern.
1867 * data.c (Qinterval): Remove; unused.
1868 (syms_of_data): Do not define 'interval'.
1869 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
1870 * window.h (decode_valid_window):
1873 * character.c, charset.c, chartab.c: Use bool for booleans.
1874 * character.c (lisp_string_width, string_count_byte8)
1875 (string_escape_byte8):

1882 (sub_char_table_set, sub_char_table_set_range)
1883 (char_table_set_range, optimize_sub_char_table)
1884 (map_sub_char_table):
1885 Use bool for boolean.
1886 * character.c (str_to_unibyte): Omit last boolean argument; it was
1887 always 0. All callers changed.
1888 * character.h, charset.h: Adjust to match previous changes.
1889 * character.h (char_printable_p): Remove decl of nonexistent function.
1890 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
1891 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
1892 are all boolean, so make them single-bit bitfields.
1894 * lisp.h (ASET): Remove attempt to detect side effects.
1895 It was meant to be temporary and it often doesn't work,
1896 because when IDX has side effects the behavior of IDX==IDX
1897 is undefined. See Stefan Monnier in
1898 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
1900 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
1902 * lisp.h (functionp): New function (extracted from Ffunctionp).
1903 (FUNCTIONP): Use it.
1904 * eval.c (Ffunctionp): Use it.
1906 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1908 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
1909 as that's faster and simpler than static storage. Don't bother
1910 with the g_main_context_query overhead if g_main_context_pending
1911 says no events are pending.
1912 (gfds, gfds_size): Remove these static vars.
1913 (xgselect_initialize): Remove; no longer needed.
1914 All uses and decls removed.
1916 * emacs.c (fatal_error_signal_hook): Remove.
1917 All uses removed. This leftover from old code was always 0.
1919 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
1920 * casefiddle.c (casify_object, casify_region):
1921 * casetab.c (set_case_table):
1922 * category.c, category.h (word_boundary_p):
1923 * category.h (CHAR_HAS_CATEGORY):
1924 Use bool for booleans, instead of int.
1926 2012-08-25 Eli Zaretskii <eliz@gnu.org>
1928 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
1930 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1932 On assertion failure, print backtrace if available.
1933 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1934 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1935 * Makefile.in (LIB_EXECINFO): New macro.
1938 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1939 * bytecode.c (exec_byte_code):
1940 * callint.c (check_mark, Fcall_interactively):
1941 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1942 (getenv_internal, sync_process_alive, call_process_exited):
1943 * lisp.h (USE_SAFE_ALLOCA):
1944 Use bool for booleans, instead of int.
1945 * lisp.h, process.h: Adjust prototypes to match above changes.
1946 * callint.c (Fcall_interactively): Don't assume the mark's
1947 offset fits in 'int'.
1949 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1951 * buffer.c, buffer.h: Use bool for boolean.
1952 * buffer.c (reset_buffer_local_variables)
1953 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1954 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

1956 (overlay_touches_p, overlay_strings, Foverlay_put)
1957 (report_overlay_modification, call_overlay_mod_hooks):
1958 (mmap_enlarge, mmap_set_vars):
1959 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1960 Use bool for booleans, instead of int.
1961 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1962 since the 1-or-0 return value is always ignored anyway.
1963 (mmap_initialized_p):
1964 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1965 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1967 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1969 * bidi.c: Use bool for boolean.
1970 This is a bit more readable, and makes the text segment of bidi.o
1971 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1972 Presumably it's faster too.
1973 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1975 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1976 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1977 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1978 (bidi_explicit_dir_char, bidi_level_of_next_char)
1979 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1980 Use bool for booleans, instead of int.
1981 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1982 (bidi_unshelve_cache): Adjust decls to match code.
1984 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1986 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1989 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1991 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1992 * atimer.h: Include <stdbool.h>.
1994 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1996 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1997 compile time tests instead of run time tests on systems that do
1999 (FRAME_MAC_P): Remove leftover from deleted code.
2000 * frame.c (syms_of_frame): Remove leftover from deleted code.
2002 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
2004 * nsterm.m (insertText:): Don't clear modifiers if code is space.
2006 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
2008 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
2009 Otherwise, the compiler complains about (A?B:C) where B is void
2010 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
2011 (fontset_add): Return void, for FONTSET_ADD.
2013 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2015 * alloc.c: Use bool for booleans.
2016 (gc_in_progress, abort_on_gc)
2017 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2018 (dont_register_blocks) [GC_MALLOC_CHECK]:
2019 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
2020 (check_string_bytes, make_specified_string, memory_full)
2021 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
2022 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
2023 (mark_stack, valid_pointer_p, make_pure_string)
2024 (Fgarbage_collect, survives_gc_p, gc_sweep):
2025 Use bool for booleans, instead of int.
2026 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2027 Remove unused local.
2028 * alloc.c (PURE_POINTER_P):
2029 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
2030 * editfns.c (Fformat):
2031 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
2033 * fns.c (sweep_weak_table):
2034 * lisp.h (suppress_checking, push_message, survives_gc_p)
2035 (make_pure_string, gc_in_progress, abort_on_gc):
2036 * lread.c (readchar, read1):
2037 * print.c (Fprin1_to_string):
2038 * xdisp.c (push_message):
2039 Use bool for booleans affected directly or indirectly by
2042 Make recently-introduced setters macros.
2043 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
2044 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
2045 (set_fontset_default, set_fontset_fallback): Rename from their
2046 upper-case counterparts, and make them functions rather than macros.
2047 This is more consistent with the other recently-introduced setters.
2048 These don't need to be inline, since they're local.
2050 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
2052 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
2053 the loop (Bug#12247).
2055 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2057 * lisp.h (vcopy): Use memcpy rather than our own loop.
2058 This fixes a performance regression introduced by the recent
2059 addition of vcopy. This means 'vcopy' will need to be modified
2060 for a copying collector, but that's OK. Also, tighten the
2061 checking in the assertion.
2063 2012-08-21 Eli Zaretskii <eliz@gnu.org>
2065 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
2066 components for RTL text (Bug#11860). Adjust X-OFFSET of each
2067 non-base glyph for the width of the base character, according to
2068 what x_draw_composite_glyph_string_foreground expects.
2069 Generate WADJUST value according to composition_gstring_width's
2070 expectations, to produce correct width of the composed character.
2071 Reverse the sign of the DU offset produced by ScriptPlace.
2073 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2075 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
2077 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2079 Avoid direct writes to contents member of struct Lisp_Vector.
2080 * lisp.h (vcopy): New function to copy data into vector.
2081 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
2082 * fns.c (Ffillarray): Use ASET.
2083 * keyboard.c (timer_check_2): Use AREF and ASET.
2084 (append_tool_bar_item, Frecent_keys): Use vcopy.
2085 * lread.c (read_vector): Use ASET.
2086 * msdos.c (Frecent_doskeys): Use vcopy.
2087 * xface.c (Finternal_copy_lisp_face): Use vcopy.
2088 (Finternal_merge_in_global_face): Use ASET and vcopy.
2089 * xfont.c (xfont_list_pattern): Likewise.
2091 2012-08-21 Martin Rudalics <rudalics@gmx.at>
2093 * window.c (Fwindow_point): For the selected window always return
2094 the position of its buffer's point.
2095 (Fset_window_point): For the selected window always go in its
2096 buffer to the specified position.
2098 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2100 Setter macros for fontsets.
2101 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
2102 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
2103 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
2106 2012-08-20 Glenn Morris <rgm@gnu.org>
2108 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
2109 Don't assume that `ln -f' works.
2111 2012-08-20 Eli Zaretskii <eliz@gnu.org>
2113 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
2114 and later about non-assignments with no effect. See discussion at
2115 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
2118 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2120 Inline setter functions for Lisp_Objects slots of struct specbinding.
2121 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
2124 2012-08-20 Martin Rudalics <rudalics@gmx.at>
2126 * window.c (select_window): Always make selected window's buffer
2129 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2131 Use AREF and ASET for docstrings of category tables.
2132 * category.h (CATEGORY_DOCSTRING): Use AREF.
2133 (SET_CATEGORY_DOCSTRING): Use ASET.
2134 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
2136 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2138 Inline setter functions for hash table members.
2139 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
2140 (set_hash_hash, set_hash_index): Rename with _slot suffix.
2141 (set_hash_key_and_value, set_hash_index, set_hash_next)
2142 (set_hash_hash): New functions.
2143 * charset.c, fns.c: Adjust users.
2145 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2147 Inline getter and setter functions for per-buffer values.
2148 * buffer.h (per_buffer_default, set_per_buffer_default)
2149 (per_buffer_value, set_per_buffer_value): New functions.
2150 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
2151 * buffer.c, data.c: Adjust users.
2153 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
2155 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
2157 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
2159 Rely on <config.h> + <unistd.h> to declare 'environ',
2160 as gnulib does this if the system doesn't.
2161 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
2162 Remove declaration. MS-Windows declares it on stdlib.h which is
2163 included by conf_post.h.
2164 * emacs.c (environ) [DOUG_LEA_MALLOC]:
2165 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
2166 * vm-limit.c: Include <unistd.h>, for 'environ'.
2168 * unexaix.c, unexcoff.c: Include "mem-limits.h".
2169 (start_of_data): Remove decl; mem-limits.h provides it.
2171 * xdisp.c (handle_invisible_prop): Make it a bit faster
2172 and avoid a gcc -Wmaybe-uninitialized diagnostic.
2174 2012-08-19 Chong Yidong <cyd@gnu.org>
2176 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
2179 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
2181 * .gdbinit: Use call instead of set when calling a function in the
2184 * data.c (set_internal): Don't use set_blv_found.
2185 (Fkill_local_variable): Likewise.
2187 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
2189 * nsfont.m (ns_ascii_average_width): Ensure the string
2190 ascii_printable is initialized with a null-terminated character
2191 array. Otherwise, it can contain undesired extra characters.
2193 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2195 port new setting code to Sun C 5.8 2005/10/13
2196 * chartab.c, lisp.h (char_table_set, char_table_set_range):
2197 Return void, not Lisp_Object. Otherwise, the compiler
2198 complains about (A?B:C) where B is void and C is Lisp_Object
2199 when compiling CHAR_TABLE_SET, due to the recent change to
2200 the API of sub_char_table_set_contents.
2202 2012-08-18 Chong Yidong <cyd@gnu.org>
2204 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
2205 for the string case (Bug#3874).
2207 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2209 * buffer.h (BSET): Remove (Bug#12215).
2210 Replace all uses with calls to new setter functions.

2238 * category.c (bset_category_table):
2239 * syntax.c (bset_syntax_table):
2240 New setter functions.
2242 * process.h (PSET): Remove (Bug#12215).
2243 Replace all uses with calls to new setter functions.
2244 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
2245 (PROCESS_INLINE): New macro.
2246 (pset_childp): New setter function.
2247 (pset_gnutls_cred_type) [HAVE_GNUTLS]: New setter function.
2248 * process.c (PROCESS_INLINE):
2249 Define to EXTERN_INLINE, so that the corresponding functions

3146 since it's used in non-static inline functions now.
3148 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

3581 * w32inevt.c: Include w32inevt.h.
3582 (w32_read_console_input): New inline function, calls either
3583 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
3584 w32_console_unicode_input.
3585 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
3586 (w32_kbd_patch_key, key_event): Use the codepage returned by
3587 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
3588 (key_event): use uChar.UnicodeChar only if
3589 w32_console_unicode_input is non-zero.
3591 * w32console.c: Include w32heap.h.
3592 <w32_console_unicode_input>: New global variable.

3616 * alloc.c (listn): Fix the order the arguments are consed onto the
3619 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
3620 enumeration constants, as PURE and HEAP are too general, and clash
3621 with other headers and sources, such as gmalloc.c and the
3622 MS-Windows system headers. All users changed.
3624 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3626 Revert last save_excursion_save and save_excursion_restore changes.
3627 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

3637 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
3639 Improve GDB symbol export (Bug#12036).
3640 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
3641 arms of an 'if', not using conditional expressions; otherwise GDB
3642 complains about the types in the unevaluated arm when the argument
3643 is an integer literal.
3644 (xgetint): Simplify expression.
3645 * alloc.c (gdb_make_enums_visible): New constant. This ports to
3646 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
3647 Zaretskii in <http://bugs.gnu.org/12036#13>.
3648 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
3649 needed now that we have gdb_make_enums_visible.
3650 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
3651 (enum enum_USE_LSB_TAG):
3652 New enum types, packaging up enums that need to be exported to GDB.
3654 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3656 Utility function to make a list from specified amount of objects.

3670 * xdisp.c (syms_of_xdisp): Likewise.
3671 * xfns.c (syms_of_xfns): Likewise.
3673 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3675 Fast save_excursion_save and save_excursion_restore.
3676 * lisp.h (struct Lisp_Excursion): New data type.
3677 (PVEC_EXCURSION): New pseudovector type.
3678 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
3679 to deal with it. Adjust comments.

3690 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
3692 Fix export of symbols to GDB (Bug#12036).
3693 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
3694 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
3695 emacs.c, as this is a more-suitable home. Had this been done earlier
3696 the fix for 12036 would have avoided some of the problems noted in
3697 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
3698 would have been more obvious.
3699 * emacs.c: Do not include <verify.h>; no longer needed.
3700 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
3701 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
3702 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3703 Remove; now done in lisp.h.
3704 * lisp.h (PUBLISH_TO_GDB): New macro.
3705 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
3706 (DATA_SEG_BITS): Use it.
3707 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
3708 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3709 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3710 not be usable in #if. This simplifies things.
3712 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
3714 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
3716 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
3718 Simplify export of symbols to GDB (Bug#12036).
3719 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3720 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3721 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3722 Adjust to changes in lisp.h and emacs.c, by using
3723 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
3724 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
3725 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
3726 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
3727 instead of gdb_valbits.
3728 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
3729 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
3730 instead of gdb_array_mark_flag.
3731 (xboolvector): Get size from $->size, not $->header.size.
3732 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
3733 (xreload, hook-run, hookpost-run): Remove.
3734 * emacs.c: Include <verify.h>.
3735 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
3736 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
3738 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
3739 (gdb_USE_LSB_TAG): New enum constants.
3740 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3741 Also define these as enum constants, so they're visible to GDB.
3742 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
3743 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
3744 as constants, so they're visible to GDB.
3745 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
3746 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
3747 Now enum constants, not macros, so they're visible to GDB.
3748 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
3749 more convenient now. All uses changed.
3750 (VALMASK) [USE_LSB_TAG]: Also define in this case.
3751 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
3753 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

3758 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
3760 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
3761 add argument, tune behavior, and adjust all callers.
3763 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
3765 Use typedef for EMACS_INT, EMACS_UINT.
3766 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
3767 than macros. This simplifies debugging in the usual case, since
3768 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
3769 and it allows expressions involving EMACS_INT casts.
3770 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
3772 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

3780 that FOCUS-FRAME can be omitted.
3782 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
3784 Adjust buffer text indirection counters at the end of Fkill_buffer.
3785 * buffer.c (Fkill_buffer): Adjust indirection counters when the
3786 buffer is definitely dead. This should really fix an issue reported
3787 by Christoph Scholtes again. (Bug#12007).
3788 (init_buffer_once): Initialize indirection counters of
3789 buffer_defaults and buffer_local_symbols (for sanity and safety).
3791 2012-07-24 Eli Zaretskii <eliz@gnu.org>
3793 * xdisp.c (init_iterator): Don't compute dimensions of truncation
3794 and continuation glyphs on tooltip frames, leave them at zero.

3797 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
3799 Simplify copy_overlay.
3800 * buffer.c (copy_overlay): Simplify. Use build_marker.

3809 it signals an error when a tooltip frame is being created.
3811 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3813 Cleanup miscellaneous objects allocation and initialization.

3820 (build_overlay): Add prototype.
3822 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3824 Swap buffer text indirection counters in Fbuffer_swap_text.
3825 * buffer.c (Fbuffer_swap_text): Swap indirections too.
3826 This avoids crash reported by Christoph Scholtes at
3827 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
3829 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
3831 * nsmenu.m (Popdown_data): New struct.
3832 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
3834 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
3835 (initWithContentRect): Make imgView and contentView non-static
3836 and autorelease them. Also autorelease img and matrix (Bug#12005).
3837 (dealloc): Remove (Bug#12005).
3839 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
3841 Adjust consing_since_gc when objects are explicitly freed.

3850 (live_buffer, set_marker_internal): New function.
3851 (Fset_marker, set_marker_restricted): Use set_marker_internal.

3854 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
3856 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
3857 as it's limited by the amount of memory, not by INT_MAX.
3859 2012-07-21 Eli Zaretskii <eliz@gnu.org>
3861 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
3862 in special-event-map. See the discussion at
3863 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
3866 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
3867 info.dwItemData. Fixes crashes on 64-bit Windows.

3921 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
3922 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
3923 Adjust users accordingly.

3942 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
3943 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
3944 'for_each_per_buffer_object_at'.
3945 All uses changed. It's better to use upper-case for macros that
3946 cannot be implemented as functions, to give the reader a clue
3947 that they're special.
3949 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
3951 * alloc.c (Fgarbage_collect): Tweak docstring.

3992 * intervals.c (merge_interval_right, merge_interval_left):
3993 Do not zero out this interval if it is absorbed by its children,
3994 as this interval's total length doesn't change in that case. See
3995 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
3997 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
3999 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
4000 when invoking (make-bool-vector N t) and N is a positive
4001 multiple of 8 -- the last 8 bits were mistakenly cleared.
4003 Remove some struct layout assumptions in bool vectors.
4004 * alloc.c (bool_header_size): New constant.
4005 (header_size, word_size): Move earlier, as they're now used earlier.
4006 Use 'word_size' in a few more places, where it's appropriate.
4007 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
4008 padding before the data member of a bool vector.
4009 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
4010 than doing the check by hand with an abort ().

4470 2012-07-11 Glenn Morris <rgm@gnu.org>
4472 * s/gnu-linux.h, s/sol2-6.h: No longer define POSIX,
4473 unused since 2011-01-17 change to systty.h.

4513 2012-07-11 Glenn Morris <rgm@gnu.org>
4515 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
4516 since nothing has defined it on these platforms.
4518 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
4519 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

4530 2012-07-11 John Wiegley <johnw@newartisans.com>
4532 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
4533 function attribute, so we only use it if it exists in the
4536 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
4538 Avoid call to strlen in fast_c_string_match_ignore_case.

4540 length argument. Adjust users accordingly.
4541 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
4543 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

4585 * s/aix4-2.h (unix): Remove; no longer needed.
4587 EMACS_TIME simplification (Bug#11875).
4588 This replaces macros (which typically do not work in GDB)
4589 with functions, typedefs and enums, making the code easier to debug.
4590 The functional style also makes code easier to read and maintain.
4591 * systime.h: Include <sys/time.h> on all hosts, not just if
4592 WINDOWSNT, since 'struct timeval' is needed in general.
4593 (EMACS_TIME): Now a typedef, not a macro.
4594 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
4596 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

4600 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
4601 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
4602 which are not functions. All uses rewritten to use:
4603 (make_emacs_time): New function.
4604 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
4605 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4606 not functions. All uses rewritten to use the following, respectively:
4607 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
4608 (add_emacs_time, sub_emacs_time): New functions.
4609 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
4610 * fileio.c (Fcopy_file):
4611 * xterm.c (XTflash): Get the current time closer to when it's used.
4612 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

4620 * gtkutil.c (get_utf8_string):
4622 * nsmenu.m (ns_update_menubar):
4623 * regex.c (regerror):
4624 Prefer memcpy to strncpy and strncat when either will do.
4625 * fileio.c (Fsubstitute_in_file_name):
4626 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
4627 (menu_separator_name_p):
4628 * nsmenu.m (ns_update_menubar):
4629 Prefer memcmp to strncmp when either will do.
4630 * nsterm.m: Include <ftoastr.h>.
4632 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
4633 Prefer snprintf to strncpy.
4634 * nsterm.m (ns_term_init):
4635 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4636 * nsterm.m (ns_term_init):
4637 Avoid the need for strncpy, by using build_string or
4638 make_unibyte_string directly. Use dtoastr, not snprintf.
4639 * process.c (Fmake_network_process): Diagnose service names that
4640 are too long, rather than silently truncating them or creating
4641 non-null-terminated names.
4642 (Fnetwork_interface_info): Likewise, for interface names.
4643 * sysdep.c (system_process_attributes) [GNU_LINUX]:
4644 Prefer sprintf to strncat.
4645 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
4646 Prefer vsnprintf to vsprintf + strncpy.
4648 2012-07-10 Glenn Morris <rgm@gnu.org>
4650 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
4651 Clarify fallback case.
4653 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4655 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
4656 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
4657 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
4658 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
4659 where argument type is known to be a Lisp_Cons.
4661 2012-07-10 Tom Tromey <tromey@redhat.com>
4663 * bytecode.c (BYTE_CODE_THREADED): New macro.
4664 (BYTE_CODES): New macro. Replaces all old byte-code defines.

4671 Optimize pure C strings initialization.
4672 * lisp.h (make_pure_string): Fix prototype.
4673 (build_pure_c_string): New function, defined as static inline. This
4674 provides a better opportunity to optimize away calls to strlen when
4675 the function is called with compile-time constant argument.
4676 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
4677 argument, adjust users accordingly. Use build_pure_c_string where
4679 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
4680 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
4681 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
4683 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4685 Avoid calls to strlen in miscellaneous functions.
4686 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
4687 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
4688 * lread.c (openp): Likewise.
4690 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4692 Avoid calls to strlen in path processing functions.
4693 * fileio.c (file_name_as_directory): Add comment. Change to add
4694 srclen argument and return the length of result. Adjust users
4696 (directory_file_name): Fix comment. Change to add srclen argument,
4697 swap 1st and 2nd arguments to obey the common convention.
4698 Adjust users accordingly.
4699 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
4701 2012-07-10 Glenn Morris <rgm@gnu.org>
4703 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
4704 Move PENDING_OUTPUT_COUNT definition to configure.
4706 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
4707 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
4708 * s/gnu.h (DATA_START): Move definitions to configure.
4710 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
4711 We include usg5-4-common.h, which defines them both.
4713 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
4714 O_RDONLY already includes it).
4716 Stop ns builds setting the EMACSLOADPATH environment variable.
4717 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4718 Now it does not set EMACSLOADPATH, just returns the load-path string.
4719 * nsterm.h: Update accordingly.
4720 * lread.c [HAVE_NS]: Include nsterm.h.
4721 (init_lread) [HAVE_NS]: Use ns_load_path.
4722 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
4724 2012-07-09 Glenn Morris <rgm@gnu.org>
4726 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
4727 since the included bsd-common.h does so.
4729 Stop ns builds setting the EMACSPATH environment variable.
4730 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
4731 (ns_init_paths): Do not set EMACSPATH.
4732 * nsterm.h (ns_exec_path): Add it.
4733 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
4736 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
4738 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
4740 * process.c (wait_reading_process_output): 'waitchannels' was unset
4741 when read_kbd || !NILP (wait_for_cell); fix this.
4743 Add GCC-style 'const' attribute to functions that can use it.
4744 * character.h (char_resolve_modifier_mask):
4745 * keyboard.h (make_ctrl_char):
4746 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
4747 (init_character_once, next_almost_prime, init_fns, init_image)
4748 (flush_pending_output, init_sound):
4749 * mem-limits.h (start_of_data):
4750 * menu.h (finish_menu_items):
4751 Add ATTRIBUTE_CONST.

4753 Declare the dummy function with ATTRIBUTE_CONST.
4754 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
4755 Add decls with ATTRIBUTE_CONST.
4757 Minor improvements to make_formatted_string.
4758 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
4759 where int is good enough, as vsprintf returns an int.
4760 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
4762 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4764 Use make_formatted_string to avoid double length calculation.
4765 * lisp.h (make_formatted_string): New prototype.
4766 * alloc.c (make_formatted_string): New function.
4767 * buffer.c (Fgenerate_new_buffer_name): Use it.
4768 * dbus.c (syms_of_dbusbind): Likewise.
4769 * editfns.c (Fcurrent_time_zone): Likewise.
4770 * filelock.c (get_boot_time): Likewise.
4771 * frame.c (make_terminal_frame, set_term_frame_name)
4772 (x_report_frame_params): Likewise.
4773 * image.c (gs_load): Likewise.
4774 * minibuf.c (get_minibuffer): Likewise.
4775 * msdos.c (dos_set_window_size): Likewise.
4776 * process.c (make_process): Likewise.
4777 * xdisp.c (ensure_echo_area_buffers): Likewise.

4789 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4791 Move marker debugging code under MARKER_DEBUG.
4792 * marker.c (MARKER_DEBUG): Move marker debugging code under
4793 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4794 for bootstrap with --enable-checking (~3x slowdown reported
4795 by Juanma Barranquero <lekktu@gmail.com>).
4796 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4798 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4800 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
4801 See <http://bugs.gnu.org/11825#29>.
4803 2012-07-08 Eli Zaretskii <eliz@gnu.org>
4805 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4806 has no font, use the frame's font. (Bug#11813)
4807 (display_line): Add commentary about displaying truncation glyphs
4809 (produce_special_glyphs): Move here from term.c.
4811 * term.c (produce_special_glyphs): Move to xdisp.c.
4813 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4816 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4818 * xdisp.c (display_line): Avoid warning about implicit declaration
4821 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4823 * lisp.h: Remove empty conditional.
4825 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4827 * lread.c (load_path_check): Now static.
4829 Fix some minor --with-ns problems found by static checking.
4830 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
4831 (x_set_font) [!HAVE_X_WINDOWS]:
4832 * image.c (xpm_load_image) [HAVE_NS]:
4833 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4834 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4835 Remove unused local.
4836 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
4837 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
4838 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
4839 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
4840 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
4841 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
4842 Fix pointer signedness problem.
4843 * xfaces.c (FRAME_X_FONT_TABLE):
4844 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
4846 2012-07-07 Glenn Morris <rgm@gnu.org>
4848 * lread.c (load_path_check): New function, split from init_lread.
4849 (init_lread): Reorganize. Motivation:
4850 If EMACSLOADPATH is set, check/warn about that rather than the
4851 defaults, which we are not going to use. Hence we can remove
4852 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4853 Don't warn if site-lisp directories are missing.
4854 If not installed, start from a blank load-path, since
4855 PATH_LOADSEARCH refers to the eventual installation directories.
4857 2012-07-07 Eli Zaretskii <eliz@gnu.org>
4859 Support truncation and continuation glyphs on GUI frames, when
4860 fringes are disabled. (Bug#11832)
4861 * xdisp.c (init_iterator): Get dimensions of truncation and
4862 continuation glyphs even if on GUI frames.
4863 Adjust it->last_visible_x on GUI frames when the left or right fringes,
4864 or both, are absent.
4865 (start_display, move_it_in_display_line_to): Handle the case of a
4866 GUI frame without a fringe to display continuation or truncation
4868 (insert_left_trunc_glyphs): Support GUI frames: make sure
4869 truncation glyphs overwrite enough glyphs from the current line to
4870 have sufficient space in pixels.
4871 (display_line): Support truncation and continuation glyphs on GUI
4872 frames. If some spare pixels are left on the line after inserting
4873 the truncation glyphs, fill that space with a stretch glyph of a
4874 suitably computed width.
4876 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4877 produce_glyphs, to support GUI sessions.
4879 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4881 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4883 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4885 Do not require float-time's arg to fit in time_t (Bug#11825).
4886 This works better on hosts where time_t is unsigned, and where
4887 float-time is applied to the (negative) difference between two times.
4888 * editfns.c (decode_time_components): Last arg is now double *,
4889 not int *, and means to store all the result as a double, without
4890 worrying about whether the seconds part fits in time_t.
4891 All callers changed.
4892 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4893 All callers changed.
4894 (Ffloat_time): Do not fail merely because the specified time falls
4895 outside of time_t range.
4897 2012-07-07 Glenn Morris <rgm@gnu.org>
4899 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
4900 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
4901 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
4903 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
4905 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
4906 Update dependencies.
4908 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.

4924 * w32fns.c (Fx_change_window_property): Doc fix.
4926 * w32fns.c (Fx_window_property): Accept the same arguments as the
4927 X Windows version. Doc fix.
4928 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4930 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4931 Eli Zaretskii <eliz@gnu.org>
4933 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.

4935 Obsolete settings removed.
4937 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4939 * process.c: Avoid unnecessary calls to gettime.
4940 (wait_reading_process_output): Don't get the time of day
4941 when gobbling data immediately and not waiting, as there's no need
4942 for it in that case. This removes a FIXME.
4944 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4946 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4947 is defined (Bug#11768).

4952 * marker.c (byte_char_debug_check): Do not perform the check
4953 if buffer is not multibyte.
4954 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4955 Call byte_char_debug_check with correct arguments.
4957 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4959 Compile marker debugging code only if ENABLE_CHECKING is defined.
4960 * marker.c (byte_char_debug_check, count_markers):
4961 Use only if ENABLE_CHECKING is defined.
4962 (byte_debug_flag): Remove.
4963 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4964 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4966 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4968 Avoid code repetition in marker-related functions.
4969 * marker.c (attach_marker): New function.

4972 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4973 Consistently rename charno to charpos.
4974 (marker_position): Add eassert.
4975 (marker_byte_position): Convert to eassert.

4988 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
4989 * composite.c (autocmp_chars): Likewise.
4990 * editfns.c (buildmark): Remove.
4991 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
4992 (save_restriction_save): Use build_marker.
4993 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
4994 * window.c (save_window_save): Likewise.
4996 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

5001 (delete_all_overlays, Fdelete_overlay): Use it.
5002 * minibuf.c (get_minibuffer): Fix comment.
5004 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5006 Port to OpenBSD 5.1 amd64.
5007 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
5008 This is needed for OpenBSD, and should be harmless on all BSD systems.
5009 Also, include <sys/sysctl.h>, as it should be available on all
5010 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
5011 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
5012 use p_pid member, not kp_proc.pid.
5014 2012-07-06 Glenn Morris <rgm@gnu.org>
5016 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
5018 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

5029 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
5031 Omit needless casts involving void * pointers and allocation.
5032 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
5033 as the former is more robust if P's type is changed.
5034 Prefer xzalloc to xmalloc + memset 0.
5035 Simplify malloc-or-realloc to realloc.
5036 Don't worry about xmalloc returning a null pointer.
5037 Prefer xstrdup to xmalloc + strcpy.
5038 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
5040 * keyboard.c (apply_modifiers_uncached): Prefer local array to
5041 alloca of a constant.

5045 * xdisp.c (display_line): Fix horizontal pixel coordinates when
5046 hscroll is larger than the line width. Fixes long and futile
5047 looping inside extend_face_to_end_of_line (on a TTY) producing
5048 glyphs that are not needed and thrown away.
5050 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5052 * marker.c (set_marker_restricted_both): Simplify by using

5064 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
5065 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
5066 followed by gtk_box_set_homogeneous (Bug#11768).
5067 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
5068 (update_theme_scrollbar_width, xg_create_scroll_bar):
5069 Use gtk_scrollbar_new (Bug#11768).
5070 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
5071 (is_box_type): New function (Bug#11768).
5072 (xg_tool_item_stale_p): Call is_box_type.
5073 (xg_initialize): Get settings by calling gtk_settings_get_for_screen

5078 * xdisp.c (window_hscroll_limited): New function.
5079 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
5080 coordinates when window's hscroll is set to insanely large
5083 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
5085 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

5146 * fileio.c (time_error_value): Check the right error number.
5147 Problem reported by Troels Nielsen in
5148 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

5152 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
5153 This should be fixed in a better way; see Eli Zaretskii in
5154 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
5155 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
5157 * fileio.c (time_error_value): Rename from special_mtime.
5158 The old name's problems were noted by Eli Zaretskii in
5159 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
5161 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
5162 This variable's comment says Emacs needs at least one GDB-visible
5163 symbol of type enum pvec_type, to work around GDB problems.
5164 The symbol's value doesn't matter.
5166 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
5167 that causes compilation to fail on pre-C99 compilers.
5169 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
5171 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

5194 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
5195 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
5196 (sweep_vectors): Use it. Use local var `total_bytes' instead of
5197 abusing vector->header.next.nbytes.
5198 (live_vector_p): Use PVEC_TYPE.
5199 (mark_object): Adapt code to extract pvectype. Use switch.
5201 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5203 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
5204 Tighten new eassert a bit.
5206 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5208 Fix compilation with --enable-gcc-warnings and -O1
5210 * doprnt.c (doprnt): Change type of tem to int, initialize
5211 to avoid compiler warning. Add eassert.
5212 * search.c (simple_search): Initialize match_byte to avoid
5213 compiler warning. Add eassert.
5215 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5217 Avoid weird behavior with large horizontal scrolls.
5218 Without this change, for example, large hscroll values would
5219 mess up Emacs's display on Fedora 15 x86, presumably due to
5220 overflows in int calculations in the display code.
5221 Also, if buffers had long lines, Emacs would freeze.
5222 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
5223 (set_window_hscroll): New function, containing the old guts of
5224 Fset_window_hscroll. Return the clipped value.
5225 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
5226 This avoids the need to check against PTRDIFF_MAX.
5228 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
5230 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

5234 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5236 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
5237 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
5238 since GCC 4.4.6 issues a bogus warning for them.
5240 Fix bugs in file timestamp newness comparisons.
5241 * fileio.c (Ffile_newer_than_file_p):
5242 * lread.c (Fload): Use full timestamp resolution of files,
5243 not just the 1-second resolution, so that files that are only
5244 slightly newer still count as newer.
5245 * fileio.c (Ffile_newer_than_file_p): Don't assume file
5246 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
5248 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
5250 * fileio.c: Improve handling of file time marker. (Bug#11852)

5257 * fileio.c (Finsert_file_contents): Properly handle st_mtime
5258 marker for non-existing file. (Bug#11852)
5260 2012-07-03 Glenn Morris <rgm@gnu.org>
5262 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
5263 and did not make it into globals.h).
5265 2012-07-03 Tom Tromey <tromey@redhat.com>

5305 * lisp.h (Frandom): Make it visible to C.
5306 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new

5312 values which aren't power of 2.
5313 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
5314 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users

5325 * alloc.c (allocate_vector_block): Remove redundant
5326 calls to mallopt if DOUG_LEA_MALLOC is defined.

5328 avoid calls to mallopt if zero_vector is returned.
5330 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5332 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
5333 is enabled, avoid dereferencing NULL current_sblock if
5336 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5338 Cleanup basic buffer management.
5339 * buffer.h (struct buffer): Change layout to use generic vector
5340 marking code. Fix some comments. Change type of 'clip_changed'
5341 to bitfield. Remove unused #ifndef old.

5352 Lisp area of struct buffer.
5353 (mark_object): Use it. Adjust marking of misc objects
5354 and related comments.
5356 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
5358 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
5359 wrapper that is not needed because the wrapped code is a no-op (zero
5360 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
5361 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
5363 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
5365 * alloc.c (mark_buffer): Simplify. Remove prototype.
5366 (mark_object): Add comment. Reorganize marking of vector-like
5367 objects. Use CHECK_LIVE for all vector-like objects except buffers
5368 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
5369 Avoid redundant calls to mark_vectorlike for bool vectors.
5371 2012-06-30 Glenn Morris <rgm@gnu.org>
5373 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
5375 * epaths.in (PATH_SITELOADSEARCH): New.
5376 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
5377 This is rather than relying on --enable-locallisppath elements
5378 having "site-lisp" in their names. (Bug#10208#25, 11658)
5380 2012-06-30 Eli Zaretskii <eliz@gnu.org>
5382 * w32proc.c (sys_select): Accept and ignore one more argument.
5384 * w32.c (emacs_gnutls_pull): Call select with one more argument.
5386 * sysselect.h [DOS_NT]: Don't include sys/select.h.
5387 (pselect) [!MS_DOS]: Redirect to sys_select.
5389 * sysdep.c: Don't include dos.h and dosfns.h.
5391 * process.c (sys_select):
5392 * msdos.c (sys_select): Accept one more argument and ignore it.
5394 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
5395 adapt data types and code to that.
5398 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
5399 which clashes with the gnulib function of the same name.
5401 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
5403 * font.c (font_style_to_value, font_style_symbolic)
5404 (font_prop_validate_style): Add type checks for values in
5407 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
5409 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
5412 2012-06-29 Eli Zaretskii <eliz@gnu.org>
5414 * xdisp.c (try_window_id): Undo last change.
5416 * w32.c (getwd): Adjust commentary about startup_dir.
5417 (init_environment): Always call sys_access, even in non-MSVC
5418 builds. Don't chdir to the directory of the Emacs executable.
5419 This undoes code from 1997 which was justified by the need to
5420 "avoid conflicts when removing and renaming directories". But its
5421 downside was that every relative file name was being interpreted
5422 relative to the directory of the Emacs executable, which can never
5423 be TRT. In particular, it broke sys_access when called with
5424 relative file names.
5425 (sys_access): Map GetLastError to errno.
5427 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5429 * window.h (struct window): Change type of 'fringes_outside_margins'

5439 Add QUIT to make the loop interruptible.
5441 2012-06-29 Glenn Morris <rgm@gnu.org>

5462 Avoid integer overflow on scroll-left and scroll-right.
5463 * window.c (HSCROLL_MAX): New macro.
5464 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
5465 overflow when requested scroll falls outside ptrdiff_t range.

5469 * window.h (struct window): Change type of 'hscroll',
5470 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
5471 'last_modified' and 'last_overlay_modified' to EMACS_INT.
5472 Adjust users accordingly.
5473 * xdisp.c (try_cursor_movement): Replace type check with eassert.
5474 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
5475 from EMACS_INT to ptrdiff_t.
5476 (make_window): Omit redundant initialization.
5478 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

5551 * alloc.c (allocate_string): Omit intervals initialization.
5552 * alloc.c (make_uninit_multibyte_string): Initialize intervals

5609 * alloc.c: Remove build_string.
5610 * lisp.h: Define build_string as static inline. This provides
5611 a better opportunity to optimize away calls to strlen when the
5612 function is called with compile-time constant argument.
5613 * image.c (imagemagick_error): Convert to build_string.
5614 * w32proc.c (sys_spawnve): Likewise.
5615 * xterm.c (x_term_init): Likewise.
5617 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
5619 Use sprintf return value instead of invoking strlen on result.
5620 In the old days this wasn't portable, since some sprintf
5621 implementations returned char *. But they died out years ago and
5622 Emacs already assumes sprintf returns int.
5623 Similarly for float_to_string.
5624 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
5625 * ccl.c (ccl_driver):
5626 * character.c (string_escape_byte8):

5629 * print.c (print_object):
5630 * xdisp.c (message_dolog):
5631 * xfns.c (syms_of_xfns):
5632 Use sprintf or float_to_string result to avoid need to call strlen.
5633 * data.c (Fnumber_to_string):
5634 Use make_unibyte_string, since the string must be ASCII.
5635 * lisp.h, print.c (float_to_string): Now returns int length.
5636 * term.c (produce_glyphless_glyph):
5637 Use sprintf result rather than recomputing it.
5639 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
5640 * Makefile.in (ALL_CFLAGS):
5641 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
5642 * gmalloc.c, regex.c: Include <config.h> unconditionally.

5647 strcasecmp if available.

5663 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
5665 * gtkutil.c (get_utf8_string): Remove redundant assignment.
5666 sprintf already null-terminates its output.
5668 * xfns.c (x_window): Remove redundant cast.
5670 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
5672 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
5673 `const char *' to `char *' to avoid compiler warning.
5675 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
5677 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
5678 instead of truncating it to 63 (admittedly a generous limit).
5680 * process.c: Fix spelling and caps in comments.
5682 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
5684 * emacs.c (setpgrp): Remove definition, unused.

5738 * keyboard.c (kbd_buffer_get_event):
5739 * process.c (Faccept_process_output):
5740 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
5741 This improves on the previous patch, which introduced a bug
5742 when time_t is unsigned and as wide as intmax_t.
5743 See <http://bugs.gnu.org/9000#51>.
5745 2012-06-23 Eli Zaretskii <eliz@gnu.org>

5761 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
5762 Privately reported by Herbert J. Skuhra.
5763 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
5765 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
5766 not make_lisp_timeval, when the argument is of type EMACS_TIME.
5768 2012-06-23 Eli Zaretskii <eliz@gnu.org>
5770 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
5771 last argument of make_unibyte_string.

5774 language ID in the event parameters.
5776 * w32term.c (w32_read_socket): Put the new keyboard codepage into
5777 event.code, not the obscure "character set ID".

5783 2012-06-23 Eli Zaretskii <eliz@gnu.org>
5785 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

5808 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5810 Support higher-resolution time stamps (Bug#9000).
5811 The time stamps are only nanosecond-resolution at the C level,
5812 since that's the best that any real-world system supports now.
5813 But they are picosecond-resolution at the Lisp level, as that's
5814 easy, and leaves room for future OS improvements.
5816 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5819 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5820 Don't get current time unless it's needed.
5822 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5823 now provides it if it's absent.
5824 (start_atimer): Port to higher-res time stamps.
5825 Check for time stamp overflow. Don't get current time more
5826 often than is needed.
5828 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5829 Include systime.h, not time.h.
5830 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
5832 * dired.c: Include stat-time.h.
5833 (Ffile-attributes): File times now have higher resolution.
5835 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
5836 (struct image): Timestamp now has higher resolution.
5838 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5839 has at least microseconds now. All uses removed.
5840 (update_frame, update_single_window, update_window, update_frame_1)
5841 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5842 (duration_to_sec_usec): Remove; no longer needed.
5844 * editfns.c (time_overflow): Now extern.
5845 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
5846 (float-time, Fformat_time_string, Fcurrent_time_string)
5847 (Fcurrent_time_zone): Accept and generate higher-resolution
5849 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
5850 (decode_time_components, lisp_seconds_argument): New functions.
5851 (make_time): Now static.
5852 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
5853 Report an error if the time is invalid, rather than having the caller
5856 * fileio.c: Include <stat-time.h>
5857 (Fcopy_file): Copy higher-resolution time stamps.
5858 Prefer to set the time stamp via a file descriptor if that works.
5859 (Fset_file_times, Finsert_file_contents, Fwrite_region)
5860 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
5861 (Fvisited_file_modtime, Fset_visited_file_modtime):
5862 Support higher-resolution time stamps.
5864 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
5866 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
5868 * image.c (prepare_image_for_display, clear_image_cache)
5869 (lookup_image): Port to higer-resolution time stamps.
5871 * keyboard.c (start_polling, bind_polling_period):
5872 Check for time stamp overflow.

5875 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5876 Port to higher-resolution time stamps. Do not assume time_t is signed.
5877 (decode_timer): New function. Timers are now vectors of length 9,
5878 not 8, to accommodate the picosecond component.
5879 (timer_check_2): Use it.
5881 * nsterm.m (select_timeout, timeval_subtract): Remove.
5882 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5883 as they're a bit more accurate and handle overflow better.
5884 (ns_select): Change prototype to be compatible with pselect.
5885 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5886 * nsterm.h (ns_select): Adjust prototype.
5888 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5889 us-resolution time stamps.
5890 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5892 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5894 * lisp.h (time_overflow): New decl.
5895 (wait_reading_process_output): First arg is now intmax_t, not int,
5896 to accommodate larger waits.
5898 * process.h (struct Lisp_Process.read_output_delay):
5899 Now counts nanoseconds, not microseconds.
5900 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
5902 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
5903 (wait_reading_process_output):
5904 Port to ns-resolution time stamps.
5905 (Faccept_process_output, wait_reading_process_output):
5906 Check for time stamp overflow. Do not assume time_t is signed.
5907 (select_wrapper): Remove; we now use pselect.
5908 (Fprocess_attributes): Now generates ns-resolution time stamps.
5910 * sysdep.c: Include utimens.h. Don't include utime.h
5911 or worry about struct utimbuf; gnulib does that for us now.
5912 (gettimeofday): Remove; gnulib provides a substitute.
5913 (make_timeval): New function.
5914 (set_file_times): Now sets ns-resolution time stamps.
5915 New arg FD; all uses changed.
5916 (time_from_jiffies, ltime_from_jiffies, get_up_time)
5917 (system_process_attributes):
5918 Now returns ns-resolution time stamp. All uses changed.
5919 Check for time stamp overflow.
5921 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5922 provides a substitute now.
5924 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5925 since it guarantees struct timespec.
5926 (EMACS_TIME): Now struct timespec, so that we can support
5927 ns-resolution time stamps.
5928 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5929 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5930 (EMACS_USECS): Remove.
5931 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5932 so multiply the arg by 1000 before storing it.
5933 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
5935 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

5941 (set_file_times, make_time, lisp_time_argument): Adjust signature.
5942 (make_timeval, make_lisp_time, decode_time_components): New decls.
5943 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
5944 that it mishandled time_t overflow. You can't compare by subtracting!
5945 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
5946 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
5948 * term.c: Include <sys/time.h>.
5949 (timeval_to_Time): New function, for proper overflow wraparound.
5950 (term_mouse_position, term_mouse_click): Use it.
5952 * undo.c (record_first_change): Support higher-resolution time stamps
5954 (Fprimitive_undo): Use them when restoring time stamps.
5956 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
5957 (w32_get_internal_run_time):
5958 Port to higher-resolution Emacs time stamps.
5959 (ltime): Now accepts single 64-bit integer, as that's more convenient
5962 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
5964 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
5965 for compatibility with pselect. Support ns-resolution time stamps.
5967 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
5969 * xselect.c (wait_for_property_change, x_get_foreign_selection):
5970 Check for time stamp overflow, and support ns-resolution time stamps.
5972 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
5973 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
5974 (timeval_subtract): Remove; no longer needed.
5975 (XTflash, XTring_bell, x_wait_for_event):
5976 Port to ns-resolution time stamps. Don't assume time_t is signed.

5982 2012-06-22 Eli Zaretskii <eliz@gnu.org>
5984 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
5985 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5986 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
5987 staticidx goes up to 1597 out of 1600 = 0x640.)
5989 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
5991 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
5992 Otherwise, the umask might be mistakenly 0 while handling input signals.
5994 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
5996 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

6002 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
6003 access to `contents' member of Lisp_Vector objects with AREF and ASET
6006 2012-06-19 Chong Yidong <cyd@gnu.org>
6008 * frame.c (delete_frame): When selecting a frame on a different
6009 text terminal, do not alter the terminal's top-frame.

6012 frame's selected window and its terminal's top-frame.
6013 (unwind_format_mode_line): Restore them.
6014 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
6016 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
6017 since tty frames can be explicitly named.
6018 (prepare_menu_bars): Likewise.
6020 * term.c (Ftty_top_frame): New function.
6022 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
6024 Port byte-code-meter to modern targets.
6025 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
6026 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
6027 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
6028 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
6029 (METER_1, METER_2): Simplify.

6035 2012-06-18 Martin Rudalics <rudalics@gmx.at>
6037 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
6038 gets killed during executing of this function (Bug#11665).
6039 Try to always return Qt when the buffer has been actually killed.
6040 (Vkill_buffer_query_functions): In doc-string say that functions
6041 run by this hook should not change the current buffer.
6043 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
6045 Fix recently-introduced process.c problems found by static checking.
6046 * process.c (write_queue_push, write_queue_pop, send_process):

6063 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
6065 * lisp.h (eassert): Assume C89 or later.
6066 This removes the need for CHECK.
6067 (CHECK): Remove. Its comments about always evaluating its
6068 argument were confusing, as 'eassert' typically does not evaluate
6071 * coding.c (produce_chars): Use ptrdiff_t, not int.
6073 * xterm.c (x_draw_underwave): Check for integer overflow.
6074 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

6260 as the union type is for debugging, not for production.
6261 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
6262 Use an inline function on all platforms when using the union type,
6263 since this is simpler and 'static inline' can be used portably

6370 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
6372 2012-06-08 Eli Zaretskii <eliz@gnu.org>
6374 * alloc.c (allocate_vectorlike): Fix last change.
6376 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
6378 Block-based vector allocation of small vectors.

6382 to denote vector blocks. Adjust users (live_vector_p,
6383 mark_maybe_pointer, valid_lisp_object_p) accordingly.
6384 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
6385 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
6386 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
6387 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
6388 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.

6405 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
6407 * doprnt.c (doprnt): Truncate multibyte char correctly.
6408 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
6409 would mishandle a string argument "Xc" if X was a multibyte
6410 character of length 2: it would truncate after X's first byte
6411 rather than including all of X.
6413 2012-06-06 Chong Yidong <cyd@gnu.org>
6415 * buffer.c (word_wrap): Doc fix.

6464 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
6465 Convert pctcpu and pctmem to Lisp float properly.
6466 Let the compiler fold better, as 100.0/0x8000 is exact.
6468 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
6470 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
6473 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
6475 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
6477 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
6479 For a 'struct window', replace some Lisp_Object fields to
6480 bitfields where appropriate, remove unused fields.
6481 * window.h (struct window): Remove unused 'last_mark_x' and
6482 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
6483 change it's type from Lisp_Object to bitfield.
6484 Change type of 'force_start', 'optional_new_start',
6485 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
6486 fields from Lisp_Object to bitfield. Adjust users accordingly.
6488 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6490 Pacify gcc -Wdouble-precision when using Xaw.
6491 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
6492 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
6493 Use 'float' consistently, rather than 'float' in most places
6494 and 'double' in a couple of places.
6496 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6498 * xdisp.c (handle_stop): Detect whether we have overlay strings
6499 loaded by testing it->current.overlay_string_index to be
6500 non-negative, instead of checking whether n_overlay_strings is
6501 positive. (Bug#11587)
6503 2012-05-31 Chong Yidong <cyd@gnu.org>
6505 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
6507 * doc.c (Fsubstitute_command_keys): Doc fix.
6509 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6511 * search.c (search_buffer): Remove calls to
6512 r_alloc_inhibit_buffer_relocation, as it is now called by
6513 maybe_unify_char, which was the cause of relocation of buffer text
6516 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6518 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6519 for the duration of call to load_charset, to avoid problems with
6520 callers of maybe_unify_char that access buffer text through C
6523 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6524 decrement the inhibition flag, instead of just setting or
6527 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6529 Remove obsolete '#define static' cruft.
6530 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6531 This #undef was "temporary" in 2000; it is no longer needed
6532 now that '#define static' has gone away.
6533 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6534 (gray_bitmap_bits): Remove; no longer needed.
6535 All uses replaced with definiens.
6536 * xterm.c: Include "bitmaps/gray.xbm".
6538 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6540 Clean up __executable_start, monstartup when --enable-profiling.
6541 The following changes affect the code only when profiling.
6542 * dispnew.c (__executable_start): Rename from safe_bcopy.
6543 Define only on platforms that need it.
6544 * emacs.c: Include <sys/gmon.h> when profiling.
6545 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6546 (__executable_start): Remove decl, since lisp.h does it now.
6547 (safe_bcopy): Remove decl; no longer has that name.
6548 (main): Coalesce #if into single bit of code, for simplicity.
6549 Cast pointers to uintptr_t, since standard libraries want integers

6576 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
6578 Do not create empty overlays with the evaporate property (Bug#9642).
6579 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6580 Bug#9642, but explicitly check that the buffer the overlay would
6581 be moved to is live and rearrange lines to make sure that errors
6582 will not put the overlay in an inconsistent state.
6583 (Fdelete_overlay): Cosmetics.
6585 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6587 * w32term.c (my_bring_window_to_top): New function.
6588 (x_raise_frame): Use handle returned by DeferWindowPos, which
6589 could be different from the original one.

6593 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6594 by calling BringWindowToTop.
6596 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6597 (WM_EMACS_END): Increase by one.
6599 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6601 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6602 This avoids undefined behavior that might cause the eassert
6603 to not catch an out-of-range value.
6605 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6607 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

6617 when referring to sectname field in printf format.
6619 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
6621 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6622 Only r_alloc_inhibit_buffer_relocation needed to be added;
6623 the others were already declared.
6625 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6626 before checking whether it's out of range. Put the check inside
6628 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6630 2012-05-27 Ken Brown <kbrown@cornell.edu>
6632 * callproc.c (Fcall_process): Restore a line that was accidentally
6633 commented out in the 2011-02-13 change (bug#11547).

6637 * lisp.h [REL_ALLOC]: Add prototypes for external functions
6638 defined on ralloc.c.
6640 * buffer.c [REL_ALLOC]: Remove prototypes of
6641 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
6642 they are now on lisp.h.
6644 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6646 * search.c (search_buffer): Use it to inhibit relocation of buffer
6647 text while re_search_2 is doing its job, because re_search_2 is
6648 passed C pointers to buffer text. (Bug#11519)
6650 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6653 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6654 state after an additional call to move_it_in_display_line_to, keep
6655 the values of it->max_ascent and it->max_descent found for the
6657 (pos_visible_p): Revert the comparison against bottom_y to what it
6658 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
6661 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6663 Fix coding-related core dumps with gcc -ftrapv.
6664 The code was computing A - B, where A and B are pointers, and B is
6665 random garbage. This can lead to core dumps on platforms that
6666 have special pointer registers, and it also leads to core dumps on
6667 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6668 A - B only when B is initialized properly.
6669 * coding.c (coding_set_source, coding_set_destination): Return void.
6670 (coding_change_source, coding_change_destinations): New functions,
6671 with the old behaviors of coding_set_source and coding_set_destination.
6672 All callers that need an offset changed to use these new functions.
6674 2012-05-26 Glenn Morris <rgm@gnu.org>
6676 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
6678 2012-05-26 Eli Zaretskii <eliz@gnu.org>

6681 * xdisp.c (draw_row_with_mouse_face):
6682 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6684 * w32console.c: Include window.h.
6685 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6687 (initialize_w32_display): Initialize mouse-highlight data.
6689 * w32inevt.c: Include termchar.h and window.h.
6690 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6691 moves, call note_mouse_highlight. If help_echo changed, call
6692 gen_help_event to produce help-echo message in the echo area.
6693 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6696 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6698 * lread.c (read1): Simplify slightly to avoid an overflow warning
6699 with GCC 4.7.0 on x86-64.
6701 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6703 * bidi.c (bidi_mirror_char): Revert last change: an int is
6704 definitely wide enough here.
6706 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
6708 Fix integer width and related bugs (Bug#9874).

6718 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6719 (allocate_pseudovector):
6720 Use int, not EMACS_INT, where int is wide enough.
6721 (inhibit_garbage_collection, Fgarbage_collect):
6722 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6723 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
6724 int might not be wide enough.
6725 (bidi_cache_search, bidi_cache_find, bidi_init_it)
6726 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)

6728 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
6729 (bidi_level_of_next_char, bidi_move_to_visually_next):
6730 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6731 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
6732 (Fkill_buffer, Fset_buffer_major_mode)
6733 (advance_to_char_boundary, Fbuffer_swap_text)
6734 (Fset_buffer_multibyte, overlays_at, overlays_in)
6735 (overlay_touches_p, struct sortvec, record_overlay_string)
6736 (overlay_strings, recenter_overlay_lists)

6738 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
6739 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
6740 (Foverlay_recenter, last_overlay_modification_hooks_used)
6741 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6742 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6743 (validate_region): Omit unnecessary test for b <= e,
6744 since that's guaranteed by the previous test.
6745 (adjust_overlays_for_delete): Avoid pos + length overflow.
6746 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6747 (report_overlay_modification):

6749 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
6750 Omit pointer cast, which isn't needed anyway, and doesn't work
6751 after the EMACS_INT -> ptrdiff_t change.
6752 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
6753 * buffer.h: Adjust decls to match defn changes elsewhere.
6754 (struct buffer_text, struct buffer):
6755 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6756 Use EMACS_INT, not int, where int might not be wide enough.
6757 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
6758 not int, to avoid needless 32-bit limit on 64-bit hosts.
6759 (exec_byte_code): Use tighter memory-full test, one that checks
6760 for alloca overflow. Don't compute the address of the object just
6761 before an array, as that's not portable. Use EMACS_INT, not
6762 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
6763 * callint.c (Fcall_interactively):
6764 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6765 * callproc.c (call_process_kill, Fcall_process):
6766 Don't assume pid_t fits into an Emacs fixnum.
6767 (call_process_cleanup, Fcall_process, child_setup):

6774 * casefiddle.c (casify_object, casify_region, operate_on_word)
6775 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
6776 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6777 (casify_object): Avoid integer overflow when overallocating buffer.
6778 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
6779 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
6780 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
6781 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6782 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6783 integers are now checked earlier. All uses replaced with XINT.
6785 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6786 For CCL_MapSingle, check that content and value are in int range.

6788 Check that Vcode_version_map_vector is a vector.
6789 (resolve_symbol_ccl_program): Check that vector header is in range.
6790 Always copy the vector, so that we can check its contents reliably
6791 now rather than having to recheck each instruction as it's being

6795 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

6797 contents are in range.
6798 (Fccl_execute_on_string): Check that status is in range.

6808 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

6842 Don't assume fixnum fits in int.

7492 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7493 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
7494 short is wide enough.
7495 (x_send_client_event): Don't assume fixnum fits in int.
7496 * xterm.c (x_x_to_emacs_modifiers):
7497 Don't assume EMACS_INT overflows nicely into int.
7498 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
7500 (handle_one_xevent): NATNUMP can eval its arg twice.
7501 (x_connection_closed):
7502 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7503 * xterm.h: Adjust decls to match defn changes elsewhere.
7504 (struct scroll_bar): Use struct vectorlike_header
7505 rather than rolling our own approximation.
7506 (SCROLL_BAR_VEC_SIZE): Remove; not used.
7508 2012-05-25 Glenn Morris <rgm@gnu.org>
7510 * lisp.mk (lisp): Update for more files being compiled now.
7512 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
7514 * lread.c: Remove `read_pure' which makes no difference.
7515 (read_pure): Remove var.
7516 (unreadpure): Remove function.
7517 (readevalloop): Don't call read_list with -1 flag.
7518 (read1, read_vector): Don't test read_pure any more.
7519 (read_list): Simplify.
7521 * fileio.c, character.h: Minor style tweaks.
7523 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
7525 * window.h (clip_changed): Remove useless declaration.
7527 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
7529 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
7530 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
7532 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
7535 This directory predates autoconf and is no longer needed nowadays.
7536 Move its few remaining bits of functionality to where they're needed.
7537 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
7538 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
7539 * m/template.h: Remove.
7540 * Makefile.in (M_FILE): Remove. All uses removed.
7541 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
7542 * lisp.h (USE_LSB_TAG):
7543 * mem-limits.h (EXCEEDS_LISP_PTR):
7544 Use VAL_MAX, not VALBITS, in #if.
7545 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
7546 (EMACS_UINT): Define unconditionally now.
7547 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
7548 (BITS_PER_EMACS_INT): New constants, replacing
7549 what used to be in config.h, but not useful in #if.
7550 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
7551 define them any more.
7552 (VAL_MAX): New macro.
7554 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
7555 BITS_PER_EMACS_INT, in #if.
7556 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
7557 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
7558 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
7559 * s/ms-w32.h (DATA_START):
7560 Move here from removed file m/intel386.h.
7561 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
7562 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
7564 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
7566 Assume C89 or later.
7567 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
7568 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
7570 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
7571 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
7572 * textprop.c, tparam.c (NULL): Remove.
7573 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
7574 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
7575 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
7576 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
7577 * xterm.c (input_signal_count): Assume volatile works.
7579 2012-05-21 Ken Brown <kbrown@cornell.edu>
7581 * xgselect.c (xg_select): Fix first argument in call to 'select'
7584 2012-05-20 Ken Brown <kbrown@cornell.edu>
7586 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
7587 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
7589 2012-05-19 Ken Brown <kbrown@cornell.edu>
7591 * xfns.c (x_in_use): Remove `static' qualifier.
7592 * xterm.h (x_in_use): Declare.
7593 * xgselect.c: Include xterm.h.
7594 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
7595 and `display_arg' (bug#9754).
7597 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
7599 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
7601 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
7602 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
7604 2012-05-18 Eli Zaretskii <eliz@gnu.org>
7606 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
7608 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
7609 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
7611 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
7612 reference to image_cache->refcount.
7613 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
7615 2012-05-17 Juri Linkov <juri@jurta.org>
7617 * search.c (Fword_search_regexp, Fword_search_backward)
7618 (Fword_search_forward, Fword_search_backward_lax)
7619 (Fword_search_forward_lax): Move functions to isearch.el
7620 (bug#10145, bug#11381).
7622 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
7624 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
7626 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
7628 * lread.c (init_obarray): Declare Qt and Qnil as special.
7630 2012-05-14 Glenn Morris <rgm@gnu.org>
7632 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
7633 Put "libexec" before "bin", for the sake of init_callproc_1.
7635 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7637 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
7639 * unexaix.c: Port to more-recent AIX compilers.
7640 (report_error, report_error_1, make_hdr, copy_sym)
7641 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
7642 Make arguments const char *, not char *, to avoid violations of C
7643 standard and to fix some AIX warnings reported by Gilles Pion.
7645 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7647 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
7648 already have overlays loaded.
7649 (handle_single_display_spec): Before returning without displaying
7650 fringe bitmap, synchronize the bidi iterator with the main display
7651 iterator, by calling iterate_out_of_display_property.
7652 (iterate_out_of_display_property): Detect buffer iteration by
7653 testing that it->string is a Lisp string.
7654 (get_next_display_element): When the current object is exhausted,
7655 and there's something on it->stack, call set_iterator_to_next to
7656 proceed with what's on the stack, instead of returning zero.
7657 (set_iterator_to_next): If called at the end of a Lisp string,
7658 proceed to consider_string_end without incrementing string
7659 position. Don't increment display vector index past the end of
7660 the display vector. (Bug#11417)
7661 (pos_visible_p): Don't report a position visible when move_it_to
7662 stopped at the last line of window, which happens to be scanned
7663 backwards by the bidi iteration. (Bug#11464)
7665 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7667 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7668 and right-margin display specs even if the spec is invalid or we
7669 are on a TTY, and thus unable to display on the fringes.
7670 That's because the text with the property will not be displayed anyway,
7671 so we need to signal to the caller that this is a "replacing"
7672 display spec. This fixes display when the spec is invalid or we
7675 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7677 * unexaix.c (make_hdr): Fix typo in prototype.
7678 This bug broke the build on AIX. Problem reported by Gilles Pion.
7680 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
7682 * keyboard.c (kbd_buffer_get_event): Read special events also in
7683 batch mode. (Bug#11415)
7685 2012-05-12 Glenn Morris <rgm@gnu.org>
7687 * ns.mk: Update for ns_appbindir no longer having trailing "/".
7689 2012-05-12 Eli Zaretskii <eliz@gnu.org>
7691 * lisp.mk (lisp): Add newcomment.elc.
7693 2012-05-12 Glenn Morris <rgm@gnu.org>
7695 * Makefile.in (MKDIR_P): New, set by configure.
7696 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
7698 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
7700 Remove unused function hourglass_started.
7701 * dispextern.h (hourglass_started):
7702 * w32fns.c (hourglass_started):
7703 * xdisp.c (hourglass_started): Remove.
7705 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7707 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7708 Update dependencies.
7710 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7712 * xgselect.c (xg_select): Put maxfds+1 into a var.
7713 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
7715 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7717 2012-05-10 Dave Abrahams <dave@boostpro.com>
7719 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7720 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7722 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7724 * dbusbind.c (xd_registered_buses): New internal Lisp object.
7725 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7726 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7727 Initialize xd_registered_buses.
7729 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7731 Untag more efficiently if USE_LSB_TAG.
7732 This is based on a proposal by YAMAMOTO Mitsuharu in
7733 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7734 For an admittedly artificial (nth 8000 longlist) benchmark on
7735 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7736 Emacs's overall text size by 1%.
7737 * lisp.h (XUNTAG): New macro.
7738 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7739 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7740 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7741 * eval.c (Fautoload):
7742 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7743 * frame.h (XFRAME): Use XUNTAG.
7745 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7746 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7747 Remove unportable assumptions about print widths of types like
7749 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7750 intptr_t when converting between pointer and integer, to avoid GCC
7751 warnings about wrong width.
7753 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7755 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7756 stack for each reader_thread, instead of defaulting to 8MB
7757 determined by the linker. This avoids failures in creating
7758 subprocesses on Windows 7, see the discussion in this thread:
7759 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7761 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7763 Fix up display of the *Minibuf-0* buffer in the mini window.
7764 * keyboard.c (read_char): Don't clear the echo area if there's no
7766 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7767 contents of *Minibuf-0*) if there's no message displayed in its stead.
7769 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7771 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7774 2012-05-06 Chong Yidong <cyd@gnu.org>
7776 * lisp.mk (lisp): Update.
7778 2012-05-05 Jim Meyering <meyering@redhat.com>
7780 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7782 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7784 * data.c (PUT_ERROR): New macro.
7785 (syms_of_data): Use it. Add new error type `user-error'.
7786 * undo.c (user_error): New function.
7787 (Fprimitive_undo): Use it.
7788 * print.c (print_error_message): Adjust print style for `user-error'.
7789 * keyboard.c (user_error): New function.
7790 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7792 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7794 Do not limit current-time-string to years 1000..9999.
7795 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7796 (Fcurrent_time_string): Support any year that is supported by the
7797 underlying localtime representation. Don't use asctime, as it
7798 has undefined behavior for years outside the range -999..9999.
7800 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7802 Fix race conditions involving setenv, gmtime, localtime, asctime.
7803 Without this fix, interrupts could mess up code that uses these
7804 nonreentrant functions, since setting TZ invalidates existing
7805 tm_zone or tzname values, and since most of these functions return
7806 pointers to static storage.
7807 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7808 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7809 Grow the critical sections to include not just invoking
7810 localtime/gmtime, but also accessing these functions' results
7811 including their tm_zone values if any, and any related TZ setting.
7812 (format_time_string): Last arg is now struct tm *, not struct tm **,
7813 so that the struct tm is saved in the critical section.
7814 All callers changed. Simplify allocation of initial buffer, partly
7815 motivated by the fact that memory allocation needs to be outside
7816 the critical section.
7818 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7820 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7821 with RESET_INTERVAL.
7823 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7824 Remove duplicated buffer name initialization.
7826 2012-05-02 Jim Meyering <jim@meyering.net>
7828 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7830 * xfns.c (x_window): Use xstrdup (Bug#11375).
7832 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7834 * xdisp.c (pos_visible_p): If already at a newline from the
7835 display string before the 'while' loop, don't walk back the glyphs
7836 from it3.glyph_row. Solves assertion violation when the display
7837 string begins with a newline (egg.el). (Bug#11367)
7839 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7841 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7844 2012-05-01 Glenn Morris <rgm@gnu.org>
7846 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7847 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7848 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7849 All were removed before 23.1.
7851 * dispnew.c: Remove HAVE_LIBNCURSES test;
7852 it is always true on relevant platforms.
7854 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7855 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7857 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
7859 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
7861 * .gdbinit (xpr): Remove checks for no longer existing misc types.
7862 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
7865 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
7867 Do not avoid creating empty evaporating overlays (Bug#9642).
7868 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7869 That is, do not delete an evaporating overlay if it becomes
7870 empty after its bounds are adjusted to fit within its buffer.
7871 This fix caused other problems, and I'm reverting it until we get
7872 to the bottom of them.
7874 2012-04-27 Chong Yidong <cyd@gnu.org>
7876 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7878 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7880 * xdisp.c (pos_visible_p): If the window start position is beyond
7881 ZV, start the display from buffer beginning. Prevents assertion
7882 violation in init_iterator when the minibuffer window is scrolled
7885 * window.c (window_scroll_pixel_based): Likewise.
7887 2012-04-27 Chong Yidong <cyd@gnu.org>
7889 * keymap.c (where_is_internal): Doc fix (Bug#10872).
7891 2012-04-27 Glenn Morris <rgm@gnu.org>
7893 * fileio.c (Fcopy_file, Fset_file_selinux_context):
7894 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
7896 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7898 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
7899 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
7901 2012-04-26 Eli Zaretskii <eliz@gnu.org>
7903 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7904 display element, check also the underlying string or buffer
7905 character. (Bug#11341)
7907 * w32menu.c: Include w32heap.h.
7908 (add_menu_item): If the call to AppendMenuW (via
7909 unicode_append_menu) fails, disable Unicode menus only if we are
7910 running on Windows 9X/Me.
7912 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7914 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
7915 (xgetint): Add missing shift for LSB tags.
7917 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7919 * keyboard.c (read_char): Don't wipe echo area for select window
7920 events: These might get delayed via `mouse-autoselect-window'
7923 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
7925 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
7926 manipulation of :loaded-from data.
7928 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
7930 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
7931 now a cons (bug#11311).
7933 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7935 Do not create empty overlays with the evaporate property (Bug#9642).
7936 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7937 if it becomes empty after its bounds are adjusted to fit within
7938 its buffer. Without this fix, in a nonempty buffer (let ((o
7939 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7940 yields an empty overlay that has the evaporate property, which is
7941 not supposed to happen.
7943 Fix minor GTK3 problems found by static checking.
7944 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7945 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7946 (struct _EmacsFixedClass, emacs_fixed_get_type):
7947 Move decls here from emacsgtkfixed.h, since they needn't be public.
7948 (emacs_fixed_get_type): Now static.
7949 (emacs_fixed_class_init): Omit unused local.

8045 since the two debugging options are incompatible.
8046 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
8048 (mem_init, mem_insert, mem_insert_fixup):
8049 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

8081 (print_object): Check for cycles even when print-circle is nil and
8082 print-gensym is t, but only check print_depth if print-circle is nil.
8084 2012-04-20 Chong Yidong <cyd@gnu.org>
8086 * process.c (wait_reading_process_output): If EIO occurs on a pty,

8142 New extern decls, to avoid calling undeclared functions.
8143 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
8144 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
8145 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

8162 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
8163 Remove decls. This fixes an "It stinks!".

8167 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
8169 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

8184 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
8185 * s/netbsd.h, s/sol2-6.h:
8186 Remove definition of GC_MARK_STACK, since the default now works.
8187 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

8215 2012-04-11 Daniel Colascione <dancol@dancol.org>
8217 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
8218 against is gone. It's better to use vfork now so that when Cygwin
8219 gains a new, working vfork, we use it automatically (bug#10398).
8221 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

8276 2012-04-09 Eli Zaretskii <eliz@gnu.org>
8278 * xdisp.c (set_cursor_from_row): If the display string appears in
8279 the buffer at position that is closer to point than the position
8280 after the display string, display the cursor on the first glyph of
8281 the display string. Fixes cursor display when a 'display' text
8282 property immediately follows invisible text. (Bug#11094)
8284 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
8286 composite.c: use 'double' consistently
8287 * composite.c (get_composition_id): Use 'double' consistently
8288 instead of converting 'float' to 'double' and vice versa; this is
8289 easier to understand and avoids a GCC warning.
8291 2012-04-09 Glenn Morris <rgm@gnu.org>
8293 * Makefile.in: Generate leim-list with bootstrap-emacs, in

8337 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
8338 [!WINDOWSNT]: New macros.
8339 (init_libxml2_functions, libxml2_loaded_p): New functions.
8340 (parse_region): Call fn_xmlCheckVersion instead of using the macro
8341 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
8342 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
8343 Calls xmlCleanupParser only if libxml2 was loaded (or statically
8345 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
8346 Call init_libxml2_functions before calling libxml2 functions.

8363 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
8364 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
8365 about subtle differences between FETCH_CHAR* and STRING_CHAR*
8366 macros related to unification of CJK characters. For the details,
8367 see the discussion following the message here:
8368 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
8370 2012-04-04 Chong Yidong <cyd@gnu.org>

8384 2012-03-31 Eli Zaretskii <eliz@gnu.org>
8386 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
8387 position we get to after a call to move_it_to fails the
8388 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
8389 only if we wind up in a string from display property. (Bug#11063)
8391 * window.c (Fdelete_other_windows_internal): Invalidate the row
8392 and column information about mouse highlight, so that redisplay
8393 restores it after reallocating the glyph matrices. (Bug#7464)
8395 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
8396 string comes from a `display' text property, use the buffer
8397 position of that property as if we actually saw that position in
8399 (move_it_by_lines): Remove the assertion that
8400 "it->current_x == 0 && it->hpos == 0" which can be legitimately
8401 violated when there's a before-string at the beginning of a line.
8404 2012-03-30 Eli Zaretskii <eliz@gnu.org>
8406 * xdisp.c (append_space_for_newline): If the default face was
8407 remapped, use the remapped face for the appended newline.
8408 (extend_face_to_end_of_line): Use the remapped default face for
8409 extending the face to the end of the line.
8410 (display_line): Call extend_face_to_end_of_line when the default
8411 face was remapped. (Bug#11068)
8413 2012-03-29 Eli Zaretskii <eliz@gnu.org>
8415 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
8417 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
8419 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
8421 2012-03-27 Glenn Morris <rgm@gnu.org>
8423 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
8426 2012-03-26 Kenichi Handa <handa@m17n.org>
8428 * dispextern.h (struct glyph): Fix previous change. Change the
8429 bit length of glyphless.ch to 25 (Bug#11082).
8431 2012-03-26 Chong Yidong <cyd@gnu.org>
8433 * keyboard.c (Vselection_inhibit_update_commands): New variable.
8434 (command_loop_1): Use it; inhibit selection update for
8435 handle-select-window too (Bug#8996).
8437 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
8439 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
8441 2012-03-25 Kenichi Handa <handa@m17n.org>
8443 * dispextern.h (struct glyph): Change the bit length of
8444 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
8446 2012-03-24 Eli Zaretskii <eliz@gnu.org>
8448 * s/ms-w32.h (tzname): Include time.h before redirecting to
8449 _tzname. Fixes the MSVC build. (Bug#9960)
8451 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
8453 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
8456 * xterm.c (XTread_socket): Only modify handling_signal if
8457 !SYNC_INPUT. (Bug#11080)
8459 2012-03-23 Eli Zaretskii <eliz@gnu.org>
8461 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
8462 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
8463 when fetching a multibyte character consumes more bytes than
8464 CHAR_BYTES returns, due to unification of CJK characters in
8465 string_char. (Bug#11073)
8467 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
8469 * process.c (wait_reading_process_output): Handle pty disconnect
8470 by refraining from sending oneself a SIGCHLD (bug#10933).
8472 2012-03-22 Chong Yidong <cyd@gnu.org>
8474 * dispextern.h (struct it): New member string_from_prefix_prop_p.
8476 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
8477 Mark string as coming from a prefix property.
8478 (handle_face_prop): Use default face for prefix strings (Bug#4281).
8479 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
8481 2012-03-21 Chong Yidong <cyd@gnu.org>
8483 * xfaces.c (Vface_remapping_alist): Doc fix.
8485 2012-03-20 Eli Zaretskii <eliz@gnu.org>
8487 * w32proc.c (Fw32_set_console_codepage)
8488 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
8491 2012-03-20 Chong Yidong <cyd@gnu.org>
8493 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
8494 to reflect default non-nil value of redisplay-dont-pause.
8496 2012-03-19 Kenichi Handa <handa@m17n.org>
8498 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
8499 it fit in a valid range (Bug#11003).
8501 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8503 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8504 that is not from display property, accept the row as a "cursor
8505 row" if one of the string's character has a non-nil `cursor'
8506 property. Fixes cursor positioning when there are newlines in
8507 overlay strings, e.g. in icomplete.el. (Bug#11035)
8509 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
8511 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
8513 2012-03-12 Chong Yidong <cyd@gnu.org>
8515 * eval.c (inhibit_lisp_code): Rename from
8516 inhibit_window_configuration_change_hook; move from window.c.
8518 * xfns.c (unwind_create_frame_1, Fx_create_frame):
8519 * window.c (run_window_configuration_change_hook)
8520 (syms_of_window): Callers changed.
8522 2012-03-11 Chong Yidong <cyd@gnu.org>

8531 is visible (Bug#10955).
8533 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
8535 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
8537 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
8539 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
8540 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8543 2012-03-03 Glenn Morris <rgm@gnu.org>
8545 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
8547 2012-03-02 Eli Zaretskii <eliz@gnu.org>
8549 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
8550 position past the first glyph_row that ends at ZV. (Bug#10902)
8551 (redisplay_window, next_element_from_string): Fix typos in
8553 (redisplay_window): Pass to move_it_vertically the margin in
8554 pixels, not in screen lines.
8556 2012-03-02 Glenn Morris <rgm@gnu.org>
8558 * buffer.c (buffer-list-update-hook): Doc fix.
8560 2012-02-29 Eli Zaretskii <eliz@gnu.org>
8562 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
8563 push_it before setting up the iterator for the first overlay
8564 string, even if we have an empty string loaded.
8565 (next_overlay_string): If there's an empty string on the iterator
8566 stack, pop the stack. (Bug#10903)
8568 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8570 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8571 Suggested by Stefan Monnier in
8572 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8573 * alloc.c (widen_to_Lisp_Object): New static function.
8574 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8575 and widening them to Lisp_Objects. This would work even if
8576 USE_LSB_TAG is defined and wide integers are used, which might
8577 happen in a future version of Emacs.
8579 2012-02-25 Chong Yidong <cyd@gnu.org>
8581 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
8584 * xselect.c (Fx_selection_exists_p): Doc fix.
8585 (x_clipboard_manager_save_all): Print an informative message
8586 before saving to clipboard manager.
8588 2012-02-24 Chong Yidong <cyd@gnu.org>
8590 * keyboard.c (process_special_events): Handle all X selection
8591 requests in kbd_buffer, not just the next one (Bug#8869).
8593 2012-02-23 Chong Yidong <cyd@gnu.org>
8595 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
8596 call when setting menu-bar-lines and tool-bar-lines parameters.
8597 (unwind_create_frame_1): New helper function.
8599 * window.c (inhibit_window_configuration_change_hook): New var.
8600 (run_window_configuration_change_hook): Obey it.
8601 (syms_of_window): Initialize it.
8603 2012-02-22 Chong Yidong <cyd@gnu.org>
8605 * xterm.c (x_draw_image_relief): Add missing type check for
8606 Vtool_bar_button_margin (Bug#10743).

8610 * fileio.c (Vfile_name_handler_alist): Doc fix.
8612 * buffer.c (Fget_file_buffer): Protect against invalid file
8613 handler return value.
8615 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
8617 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
8618 when computing $valmask.
8620 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8621 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8622 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8623 It's useless in that case, and it can cause problems on hosts
8624 that allocate halves of EMACS_INT values separately.
8625 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8626 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8627 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8628 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8629 it avoids undefined behavior on hosts where shifting right by more
8630 than the word width has undefined behavior.
8632 2012-02-19 Chong Yidong <cyd@gnu.org>
8634 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
8635 (Funhandled_file_name_directory, Ffile_name_as_directory)
8636 (Fdirectory_file_name, Fexpand_file_name)
8637 (Fsubstitute_in_file_name): Protect against invalid file handler
8638 return values (Bug#10845).
8640 2012-02-18 Eli Zaretskii <eliz@gnu.org>
8642 * .gdbinit (pitx): Fix incorrect references to fields of the
8645 2012-02-17 Chong Yidong <cyd@gnu.org>
8647 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
8649 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
8651 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
8652 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
8654 2012-02-15 Chong Yidong <cyd@gnu.org>
8656 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
8657 marked as special. Also, starting docstrings with * is obsolete.
8659 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
8661 * gnutls.c (emacs_gnutls_write): Fix last change.
8663 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

8672 2012-02-12 Chong Yidong <cyd@gnu.org>
8674 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
8675 as that creates a dangerous corner case.
8677 * window.c (Fdelete_window_internal): Invalidate the mouse
8678 highlight (Bug#9904).
8680 2012-02-12 Glenn Morris <rgm@gnu.org>
8682 * xselect.c (Fx_own_selection_internal)
8683 (Fx_get_selection_internal, Fx_disown_selection_internal)
8684 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
8685 * nsselect.m (Fx_own_selection_internal)
8686 (Fx_disown_selection_internal, Fx_selection_exists_p)
8687 (Fx_selection_owner_p, Fx_get_selection_internal):
8688 Sync docs and argument specs with the xselect.c versions.
8690 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
8692 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
8694 2012-02-11 Eli Zaretskii <eliz@gnu.org>

8706 2012-02-09 Kenichi Handa <handa@m17n.org>
8708 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
8710 2012-02-07 Chong Yidong <cyd@gnu.org>
8712 * buffer.c (Fbuffer_local_variables)
8713 (buffer_lisp_local_variables): Handle unbound vars correctly;
8714 don't let Qunbound leak into Lisp.
8716 2012-02-07 Glenn Morris <rgm@gnu.org>
8718 * image.c (Fimagemagick_types): Doc fix.
8720 * image.c (imagemagick-render-type): Change it from a lisp object
8721 to an integer. Move the doc here from the lisp manual.
8722 Treat all values not equal to 0 the same.
8724 2012-02-06 Chong Yidong <cyd@gnu.org>
8726 * doc.c (store_function_docstring): Avoid applying docstring of
8727 alias to base function (Bug#2603).
8729 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
8731 * .gdbinit (pp1, pv1): Remove redundant defines.
8734 2012-02-04 Chong Yidong <cyd@gnu.org>
8736 * nsterm.m: Declare a global (Bug#10694).
8738 2012-02-04 Eli Zaretskii <eliz@gnu.org>
8740 * w32.c (get_emacs_configuration_options):
8741 Include --enable-checking, if specified, in the return value.
8743 2012-02-04 Martin Rudalics <rudalics@gmx.at>
8745 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
8746 after rounding frame sizes. (Bug#9723)
8748 2012-02-04 Eli Zaretskii <eliz@gnu.org>
8750 * keyboard.c (adjust_point_for_property): Don't position point
8751 before BEGV. (Bug#10696)
8753 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
8755 Handle overflow when computing char display width (Bug#9496).
8756 * character.c (char_width): Return EMACS_INT, not int.
8757 (char_width, c_string_width): Check for overflow when
8758 computing the width; this is possible now that individual
8759 characters can have unbounded width. Problem introduced
8760 by merge from Emacs 23 on 2012-01-19.
8762 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
8764 * dbusbind.c (Fdbus_register_method): Mention the return value
8765 :ignore in the docstring.
8767 2012-02-02 Glenn Morris <rgm@gnu.org>

8777 2012-02-02 Kenichi Handa <handa@m17n.org>
8779 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
8780 0, do not call append_composite_glyph.
8782 2012-02-02 Kenichi Handa <handa@m17n.org>
8784 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
8786 (x_produce_glyphs): If the component of a composition is a null
8787 string, set it->pixel_width to 1 to avoid zero-width glyph.
8789 2012-02-01 Eli Zaretskii <eliz@gnu.org>
8791 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
8792 first 2 arguments are identical. This makes inserting large
8793 output from a subprocess an order of magnitude faster on
8794 MS-Windows, where all sbrk'ed memory is always contiguous.
8796 2012-01-31 Glenn Morris <rgm@gnu.org>
8798 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

8806 2012-01-28 Samuel Thibault <sthibault@debian.org> (tiny change)
8808 * s/gnu.h: Define POSIX_SIGNALS (Bug#10552).
8810 2012-01-28 Chong Yidong <cyd@gnu.org>
8812 * minibuf.c (syms_of_minibuf): Doc fix (Bug#10550).
8814 2012-01-26 Chong Yidong <cyd@gnu.org>

8834 2012-01-21 Chong Yidong <cyd@gnu.org>
8836 * floatfns.c (Fcopysign): Make the second argument non-optional,
8837 since nil is not allowed anyway.
8839 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
8841 * process.c (read_process_output): Use p instead of XPROCESS (proc).
8842 (send_process): Likewise.
8844 2012-01-19 Martin Rudalics <rudalics@gmx.at>
8846 * window.c (save_window_save, Fcurrent_window_configuration)

8848 Rewrite doc-strings.
8850 2012-01-19 Kenichi Handa <handa@m17n.org>
8852 * character.c (char_width): New function.
8853 (Fchar_width, c_string_width, lisp_string_width):
8854 Use char_width (Bug#9496).
8856 2012-01-16 Martin Rudalics <rudalics@gmx.at>
8858 * window.c (Vwindow_persistent_parameters): New variable.
8859 (Fset_window_configuration, save_window_save): Handle persistent
8862 2012-01-14 Eli Zaretskii <eliz@gnu.org>
8864 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid
8865 thrashing the stack of the thread. (Bug#9087)
8867 2012-01-12 Paul Eggert <eggert@cs.ucla.edu>
8869 * xdisp.c (rows_from_pos_range): Add parens as per gcc -Wparentheses.

8874 highlight ends on a newline. (Bug#10464)
8875 (mouse_face_from_buffer_pos): Fix off-by-one error in calculating
8876 he end column for display of highlight that ends on a newline
8879 2012-01-11 Glenn Morris <rgm@gnu.org>
8881 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
8882 from load-path also when installation-directory is nil. (Bug#10208)
8884 2012-01-10 Glenn Morris <rgm@gnu.org>
8886 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
8888 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
8889 Update template values to be closer to their typical values these days.
8891 2012-01-09 Eli Zaretskii <eliz@gnu.org>
8893 * xdisp.c (rows_from_pos_range): Accept additional argument
8894 DISP_STRING, and accept any glyph in a row whose object is that
8895 string as eligible for mouse highlight. Fixes mouse highlight of
8896 display strings from overlays. (Bug#10464)
8898 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
8900 emacs: fix an auto-save permissions race condition (Bug#10400)
8901 * fileio.c (auto_saving_dir_umask): New static var.
8902 (Fmake_directory_internal): Use it.
8903 (do_auto_save_make_dir): Set it, instead of invoking chmod after
8904 creating the directory. The old code temporarily assigns
8905 too-generous permissions to the directory.
8906 (do_auto_save_eh): Clear it.

9409 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
9410 Otherwise, valgrind does not work on some platforms.
9411 Problem reported by Andreas Schwab in
9412 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
9413 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
9414 is set, removing the need for VIRT_ADDRESS_VARIES.
9415 (PURE_P): Use a more-efficient implementation that needs just one
9416 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
9417 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
9418 to 4 (xorl, subq, cmpq, setbe).
9419 * alloc.c (pure): Always extern now, since that's the
9420 VIRT_ADDR_VARIES behavior.
9421 (PURE_POINTER_P): Use a single comparison, not two, for
9422 consistency with the new puresize.h.
9423 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
9424 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
9425 Remove VIRT_ADDR_VARIES no longer needed.

9430 (erase_phys_cursor, update_window_cursor, show_mouse_face)
9431 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
9432 behave as if the cursor position were at the window margin.
9434 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
9435 and the cursor position is out of bounds, behave as if the cursor
9436 position were at the window margin. (Bug#10075)
9438 2011-11-18 Chong Yidong <cyd@gnu.org>
9440 * window.c (Fwindow_combination_limit): Make first argument

9462 compute_line_metrics.
9463 (compute_line_metrics): Call row_hash, instead of computing the
9466 * dispnew.c (verify_row_hash): Call row_hash for computing the
9467 hash code of a row, instead of duplicating code from xdisp.c.

9505 * image.c (imagemagick_load_image): Fix typo.
9507 2011-11-14 Eli Zaretskii <eliz@gnu.org>
9509 * xdisp.c (display_line): Move the call to
9510 highlight_trailing_whitespace before the call to
9511 compute_line_metrics, since the latter needs to see the final
9512 faces of all the glyphs to compute ROW's hash value.
9513 Fixes assertion violations in row_equal_p. (Bug#10035)
9515 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
9517 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

9522 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
9523 with user-defined heap size. Bump the default size of the temacs
9524 heap to 27MB, to avoid memory warning when running temacs.
9525 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
9527 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

9574 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
9576 Avoid some portability problems by eschewing 'extern inline' functions.
9577 The trivial performance wins aren't worth the portability hassles; see
9578 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
9580 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

9582 (window_box_right, window_box_right_offset): Undo previous change,
9583 by removing the "extern"s.
9584 * intervals.c (adjust_intervals_for_insertion)
9585 (adjust_intervals_for_deletion): Undo previous change,
9586 making these static again.
9587 (offset_intervals, temp_set_point_both, temp_set_point)
9588 (copy_intervals_to_string): No longer inline.
9589 * xdisp.c (window_text_bottom_y, window_box_width)

9655 (window_box_right, window_box_right_offset): Declare extern.
9656 Otherwise, these inline functions do not conform to C99 and
9657 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
9658 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
9659 * intervals.c (adjust_intervals_for_insertion)
9660 (adjust_intervals_for_deletion): Now extern, because otherwise the
9661 extern inline functions 'offset_intervals' couldn't refer to it.
9662 (static_offset_intervals): Remove.
9663 (offset_intervals): Rewrite using the old contents of
9664 static_offset_intervals. The old version didn't conform to C99
9665 because an extern inline function contained a reference to an
9666 identifier with static linkage.

9688 (Fwindow_vscroll): Doc fix.
9689 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
9690 argument, since it makes no sense to pass a live window and for
9691 consistency with window-child.

9718 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
9719 (unwind_create_frame): New function (Bug#9943).
9720 (Fx_create_frame): Restructure code to be more similar to the one in
9721 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
9722 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
9723 Move terminal->reference_count++ just before making the frame official

9874 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
9876 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
9878 * window.c (make_window): Initialize phys_cursor_on_p.
9880 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
9882 * lisp.h (struct Lisp_Symbol): Update comments.
9884 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
9886 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
9888 2011-10-28 Eli Zaretskii <eliz@gnu.org>
9890 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
9891 <oslsachem@gmail.com> for helping to debug this.
9893 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
9894 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
9895 (g_b_init_get_glyph_outline_w): New static variables.
9896 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
9897 (GetGlyphOutlineW_Proc): New typedefs.
9898 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
9899 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
9901 (w32font_open_internal, compute_metrics):
9902 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
9903 instead of calling the "wide" APIs directly.
9905 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
9907 * w32.h (syms_of_w32font): Add prototype.
9909 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9911 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
9912 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
9913 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
9914 (Fmove_to_window_line): Doc fix.
9916 2011-10-27 Chong Yidong <cyd@gnu.org>
9918 * process.c (make_process): Set gnutls_state to NULL.
9920 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
9921 non-NULL, regardless of GNUTLS_INITSTAGE.
9922 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
9923 an error. Set process slots as soon as we allocate them.
9925 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
9927 2011-10-27 Chong Yidong <cyd@gnu.org>
9929 * gnutls.c (emacs_gnutls_deinit): New function.
9930 Deallocate credentials structures as well as calling gnutls_deinit.
9931 (Fgnutls_deinit, Fgnutls_boot): Use it.
9933 * process.c (make_process): Initialize GnuTLS credentials to NULL.
9934 (deactivate_process): Call emacs_gnutls_deinit.
9936 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9938 * image.c (x_create_x_image_and_pixmap):
9939 * w32.c (sys_rename, w32_delayed_load):
9940 * w32font.c (fill_in_logfont):
9941 * w32reg.c (x_get_string_resource): Silence compiler warnings.
9943 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
9945 * w32fns.c (w32_default_color_map): New function,
9946 extracted from Fw32_default_color_map.
9947 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
9949 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
9951 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
9953 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
9955 * keyboard.c (test_undefined): New function (bug#9751).
9956 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
9958 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
9960 * sysdep.c (init_sys_modes): Fix the check for the controlling
9961 terminal (Bug#6649).
9963 2011-10-20 Eli Zaretskii <eliz@gnu.org>
9965 * dispextern.h (struct bidi_it): New member next_en_type.
9967 * bidi.c (bidi_line_init): Initialize the next_en_type member.
9968 (bidi_resolve_explicit_1): When next_en_pos is valid for the
9969 current character, check also for next_en_type being WEAK_EN.
9970 (bidi_resolve_weak): Don't enter the expensive loop if the current
9971 position is before next_en_pos. Record the bidi type of the first
9972 non-ET, non-BN character we find, in addition to its position.
9973 (bidi_level_of_next_char): Invalidate next_en_type when
9974 next_en_pos is over-stepped.
9976 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
9978 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
9979 * editfns.c: Rewrite current-time-zone so that it invokes
9980 the equivalent of (format-time-string "%Z") to get the time zone name.
9981 This fixes a bug when the time zone name contains characters that
9982 need converting from the system time locale to Emacs internal format.
9983 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9984 that patch fixed format-time-string to do the conversion, but
9985 I forgot to fix current-time-zone.
9986 (format_time_string): New function, containing most of
9987 what Fformat_time_string used to contain.
9988 (Fformat_time_string): Rewrite in terms of format_time_string.
9989 This doesn't change this function's behavior.
9990 (current-time-zone): Rewrite to use format_time_string.
9991 This fixes the bug reported by Michael Schierl in
9992 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9993 Jason Rumney's 2007-06-07 change worked around this bug, but
9995 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9997 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9999 * xdisp.c (start_display): If the character at POS is displayed
10000 via a display vector, reset IT->current.dpvec_index to zero.
10001 (try_window_reusing_current_matrix): If a line ends in a display
10002 vector or the next line starts in a display vector, continue
10003 redrawing the window even though the character position of
10004 start_row was reached.
10007 2011-10-18 Chong Yidong <cyd@gnu.org>
10009 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
10010 with nobreak-char-display too.
10012 2011-10-18 Eli Zaretskii <eliz@gnu.org>
10014 Fix part 3 of bug#9771.
10015 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
10016 (bidi_resolve_neutral): Don't enter the expensive loop looking for
10017 non-neutral characters if the current character is a paragraph
10018 separator (a.k.a. Newline). This avoids running the same
10019 expensive loop twice, once when we consume the preceding newline
10020 and the other time when the line actually needs to be displayed.
10021 Avoid the loop when we see neutrals on the base embedding level
10022 following a character whose directionality is the same as the
10023 paragraph's. This avoids running the expensive loop when a line
10024 ends in a long sequence of neutrals, like control characters.
10025 Add assertion against STRONG_AL type. Slightly rearrange code
10026 that determines the type of a neutral given the first non-neutral
10028 (bidi_level_of_next_char): Set next_en_pos to zero when
10029 invalidating its info.
10031 2011-10-17 Eli Zaretskii <eliz@gnu.org>
10033 * xdisp.c (push_display_prop): Determine whether to record string
10034 or buffer position by IT->string, not by IT->method. Allow
10035 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
10036 (move_it_vertically_backward): Don't look for character position
10037 immediately after the newline when in a continuation line.
10040 2011-10-15 Martin Rudalics <rudalics@gmx.at>
10042 * window.c (coordinates_in_window): Rewrite and delabelize
10043 vertical border check. (Bug#5357) (Bug#9618)
10045 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
10047 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
10048 errors in XSetWindowBorder (bug#9310).
10050 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
10052 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
10053 avoid crash when xmalloc overrun checking is enabled.
10055 2011-10-13 Eli Zaretskii <eliz@gnu.org>
10057 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
10058 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
10059 cursor motion with <left> and <right> arrow keys.
10061 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
10062 some callers set that themselves.
10064 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10066 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
10067 display string and the previous row comes from the same string and
10068 is empty. (Bug#9739) (Bug#9738)
10070 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
10072 * doc.c (get_doc_string): Encode file name (bug#9735).
10074 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10076 * bidi.c (bidi_level_of_next_char):
10077 * xdisp.c (get_visually_first_element): Remove old incorrect
10078 comments regarding the Unicode Line Separator character.
10080 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
10082 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
10084 * alloc.c (Fgc_status): Do not access beyond zombies array
10085 boundary if nzombies > MAX_ZOMBIES.
10086 * alloc.c (dump_zombies): Add missing format specifier.
10088 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
10090 * xdisp.c (set_cursor_from_row): Simplify conditionals,
10091 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
10093 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
10094 Some packages use them to denote characters with modifiers.
10096 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
10098 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
10099 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
10100 matching a pp-number. Rename parameter var to var1.
10102 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
10104 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
10106 2011-10-08 Glenn Morris <rgm@gnu.org>
10108 * callint.c (Fcall_interactively): Give a more explicit error for the
10109 'c' case with a non-character input. (Bug#8479)
10111 2011-10-08 Eli Zaretskii <eliz@gnu.org>
10113 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
10115 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
10116 lines that are hscrolled on the left.
10118 * dispnew.c (buffer_posn_from_coords): Account for a possible
10119 presence of header-line. (Bug#4426)
10121 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
10123 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
10124 Don't advertise functionality which we discourage or doesn't work.
10126 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
10128 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
10129 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
10130 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
10131 this makes Emacs dump core during garbage collection on rare
10132 occasions. sizeof is obviously inferior to offsetof here, so
10133 stick with offsetof.
10134 (GC_POINTER_ALIGNMENT): New macro.
10135 (mark_memory): Omit 3rd (offset) arg; caller changed.
10136 Don't assume EMACS_INT alignment is the same as pointer alignment.
10138 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
10140 * keyboard.c (read_key_sequence_remapped): New var.
10141 (read_key_sequence): Compute remapping in the right buffer.
10142 (command_loop_1): Use read_key_sequence's remapping directly.
10144 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
10146 * dired.c (file_name_completion): Don't expand file name.
10147 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
10148 before checking file name handler.
10150 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
10151 they've been requested explicitly (bug#9591).
10153 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
10155 * keymap.c (Fsingle_key_description): Use make_specified_string
10156 instead of build_string to build string from push_key_description.
10159 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10161 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
10162 This fixes a Y2038 bug on 64-bit hosts.
10163 * buffer.c (reset_buffer):
10164 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
10165 (Fclear_buffer_auto_save_failure):
10166 Use 0, not -1, to represent an unset failure time, since time_t
10167 might not be signed.
10169 Remove dependency on glibc malloc internals.
10170 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10171 Move back here from lisp.h, but with their new implementations.
10172 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10173 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
10174 * charset.c (charset_table_init): New static var.
10175 (syms_of_charset): Use it instead of xmalloc. This removes a
10176 dependency on glibc malloc internals. See Eli Zaretskii's comment in
10177 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
10178 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10179 Move back to alloc.c.
10180 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10181 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
10183 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
10185 * nsterm.m (windowDidResize): Call x_set_window_size only when
10186 ns_in_resize is true. Otherwise set pixelwidth/height and
10187 call change_frame_size (Bug#9628).
10189 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10191 Port --enable-checking=all to Fedora 14 x86-64.
10192 * charset.c (syms_of_charset): Also account for glibc malloc's
10193 internal overhead when calculating the initial malloc maximum.
10195 Port --enable-checking=all to Fedora 14 x86.
10196 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10198 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
10199 (overrun_check_realloc, overrun_check_free):
10200 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
10201 That way, xmalloc returns a properly-aligned pointer even if
10202 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
10203 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
10204 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
10205 into account when calculating the initial malloc maximum.
10206 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10207 Move here from alloc.c, so that charset.c can use it too.
10208 Properly align; the old code wasn't right for common 32-bit hosts
10209 when configured with --enable-checking=all.
10210 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10211 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
10213 2011-09-29 Eli Zaretskii <eliz@gnu.org>
10215 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
10218 2011-09-28 Eli Zaretskii <eliz@gnu.org>
10220 * xdisp.c (compute_display_string_end): If there's no display
10221 string at CHARPOS, return -1.
10223 * bidi.c (bidi_fetch_char): When compute_display_string_end
10224 returns a negative value, treat the character as a normal
10225 character not covered by a display string. (Bug#9624)
10227 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
10229 * lread.c (Fread_from_string): Fix typo in docstring.
10231 2011-09-27 Eli Zaretskii <eliz@gnu.org>
10233 * xdisp.c (handle_invisible_prop): If invisible text ends on a
10234 newline, reseat the iterator instead of bidi-iterating there one
10235 character at a time. (Bug#9610)
10236 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
10237 TO_CHARPOS if the bidi iterator is at base embedding level.
10239 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
10241 * lread.c (readevalloop): Use correct code for NBSP.
10242 (read1): Likewise. (Bug#9608)
10244 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
10246 * dbusbind.c (Fdbus_register_signal): When service is not
10247 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
10249 2011-09-25 Glenn Morris <rgm@gnu.org>
10251 * buffer.c (truncate-lines): Doc fix.
10253 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
10255 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
10256 (Fset_window_next_buffers): Doc fix.
10258 2011-09-24 Glenn Morris <rgm@gnu.org>
10260 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
10262 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
10264 Fix minor problems found by static checking.
10265 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
10266 * indent.c (Fvertical_motion): Fix == vs = typo.
10268 2011-09-24 Eli Zaretskii <eliz@gnu.org>
10270 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
10271 Default value is now t. Doc fix.
10273 * indent.c (Fvertical_motion): Compute and apply the overshoot
10274 logic when moving up, not only when moving down. Fix the
10275 confusing name and values of the it_overshoot_expected variable;
10276 logic changes accordingly. (Bug#9254) (Bug#9549)
10278 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
10279 CHARPOS is covered by a display string which includes newlines.
10280 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
10281 is covered by a display string with embedded newlines.
10283 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
10285 * dbusbind.c (Fdbus_register_signal): Add match rule to
10286 Vdbus_registered_objects_table. (Bug#9581)
10287 (Fdbus_register_method, Vdbus_registered_objects_table):
10290 2011-09-24 Jim Meyering <meyering@redhat.com>
10292 do not ignore write error for any output size
10293 The previous change was incomplete.
10294 While it makes emacs --batch detect the vast majority of stdout
10295 write failures, errors were still ignored whenever the output size is
10296 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
10297 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
10298 && echo FAIL: ignored write error
10299 FAIL: ignored write error
10300 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
10301 && echo FAIL: ignored write error
10302 FAIL: ignored write error
10303 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
10305 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
10307 * emacs.c (Fkill_emacs): In noninteractive mode exit
10308 non-successfully if a write error occurred on stdout. (Bug#9574)
10310 2011-09-21 Eli Zaretskii <eliz@gnu.org>
10312 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
10315 * dispextern.h (struct it): Update the comment documenting what
10318 2011-09-20 Eli Zaretskii <eliz@gnu.org>
10320 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
10321 a display string, extend search for cursor position to end of row.
10322 (find_row_edges): If the row ends in a newline from a display
10323 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
10324 Handle the case of a display string with multiple newlines.
10325 (Fcurrent_bidi_paragraph_direction): Fix search for previous
10326 non-empty line. Fixes confusing cursor motion with arrow keys at
10327 the beginning of a line that starts with whitespace.
10329 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10331 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
10334 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
10336 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
10337 boolean (Bug#9154).
10339 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10341 * xdisp.c (display_line): Record maximum and minimum buffer
10342 positions even if no glyphs were produced (e.g., by a zero-width
10343 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
10344 buffer positions that will be removed from the glyph row because
10346 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
10347 column is beyond frame width: don't subtract 1 "pixel" when
10348 computing width of the stretch.
10349 (reseat_at_next_visible_line_start): Undo the change made on
10350 2011-09-17 that saved paragraph information and restored it after
10351 the call to `reseat'. (Bug#9545)
10353 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10355 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
10356 and turn window cursor on if cleared (Bug#9415).
10358 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
10360 * search.c (boyer_moore): Take unibyte characters from pattern
10361 literally. (Bug#9458)
10363 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10365 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
10367 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
10369 Fix minor problem found by static checking.
10370 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
10371 initialized, to pacify gcc -Wuninitialized.
10373 * fileio.c: Report proper errno when syscall falls.
10374 (Finsert_file_contents): Save and restore errno,
10375 so that report_file_error outputs the correct diagnostic.
10376 (Fwrite_region) [CLASH_DETECTION]: Likewise.
10378 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10380 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
10382 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10384 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
10385 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
10387 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10389 * xdisp.c (reseat_at_next_visible_line_start): Keep information
10390 about the current paragraph and restore it after the call to reseat.
10392 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
10393 (bidi_find_paragraph_start): Search back for paragraph beginning
10394 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
10395 (bidi_move_to_visually_next): Only trigger paragraph-related
10396 computations when the last character is a newline or at EOB, not
10397 just any NEUTRAL_B. (Bug#9470)
10399 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
10400 truncated lines if point is covered by a display string. (Bug#9524)
10402 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
10404 * xselect.c: Relax test for outgoing X longs (Bug#9498).
10405 (cons_to_x_long): New function.
10406 (lisp_data_to_selection_data): Use it. Correct the test for
10407 short-versus-long data; it was negated. Break out of vector
10408 loop, for efficiency, when a long datum is discovered.
10410 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
10412 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
10414 2011-09-16 Eli Zaretskii <eliz@gnu.org>
10416 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
10417 GCC PR/17406) by declaring this function with external scope.
10419 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10421 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
10422 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
10424 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
10426 * editfns.c (Fformat): Correctly handle text properties on "%%".
10428 2011-09-15 Eli Zaretskii <eliz@gnu.org>
10430 * xterm.c (x_draw_composite_glyph_string_foreground):

10432 * term.c (encode_terminal_code):
10433 * composite.c (composition_update_it, get_composition_id):
10434 * xdisp.c (get_next_display_element)
10435 (fill_composite_glyph_string): Add comments about special meaning
10436 of TAB characters in a composition.
10438 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10440 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
10441 This occurs when processing a multibyte format.
10442 Problem reported by Wolfgang Jenker.
10444 2011-09-15 Johan Bockgård <bojohan@gnu.org>
10446 * xdisp.c (try_cursor_movement): Only check for exact match if
10447 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
10449 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10451 Remove unused external symbols.
10452 * dispextern.h (calc_pixel_width_or_height): Remove decl.
10453 * xdisp.c (calc_pixel_width_or_height): Now static.
10454 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
10455 * indent.c (check_display_width):
10456 * w32term.c: Fix comment to match code.
10457 * xterm.c, xterm.h (x_catching_errors): Remove.
10459 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10461 * xselect.c: Use signed conversions more consistently (Bug#9498).
10462 (selection_data_to_lisp_data): Assume incoming selection data are
10463 signed integers, not unsigned. This is to be consistent with
10464 outgoing selection data, which was modified to use signed integers
10465 in as part of the fix to Bug#9196 in response to Jan D.'s comment
10466 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
10467 expects long, not unsigned long.
10469 2011-09-14 Eli Zaretskii <eliz@gnu.org>
10471 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
10472 computation of loop end. Reported by Johan Bockgård
10475 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
10477 * frame.c (Fother_visible_frames_p): Function deleted.
10479 2011-09-12 Eli Zaretskii <eliz@gnu.org>
10481 * indent.c (compute_motion): Process display vector front to back
10482 rather than the other way around. (Bug#2496)
10484 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
10486 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
10488 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
10490 * minibuf.c (Fread_from_minibuffer): Doc fix.
10492 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10494 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
10495 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
10497 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
10499 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
10500 value for non-existent files.
10502 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10504 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10505 set its "size" to -1. This will set the modtime_size field of
10506 the corresponding buffer to -1, which is what
10507 verify-visited-file-modtime expects for files that do not exist.
10510 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
10512 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10514 * lisp.h: ... from here. push_key_description is no longer
10515 defined in keyboard.c, so its declaration should not be in
10516 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10517 logically belongs with push_key_description.
10519 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10521 * buffer.h: Include <sys/types.h> instead of <time.h>.
10522 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
10523 Problem reported by Herbert J. Skuhra.
10525 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
10527 * xml.c (parse_region): Make the parsing work for
10528 non-comment-starting XML files again (bug#9144).
10530 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
10532 * image.c (gif_load): Fix calculation of bottom and right corner.
10535 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10537 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10538 redisplay in small windows.
10540 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10542 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10544 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10546 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10547 Operate on live windows only.
10549 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10551 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10553 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10555 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10556 only under bidi iteration.
10558 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10560 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10562 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10564 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10565 Without this fix, the command to link temacs failed due to an
10566 undefined symbol __builtin_isnan. This is because
10567 /usr/include/iso/math_c99.h #defines isnan(x) to
10568 __builtin_isnan(x), but the bundled gcc, which identifies itself
10569 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10571 * floatfns.c (isnan): #undef, and then #define to a clone of
10573 (Fisnan): Always define, since it's always available now.
10574 (syms_of_floatfns): Always define isnan at the Lisp level.
10576 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10578 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10580 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10582 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10583 The previous code assumed that file offsets (off_t values) fit in
10584 EMACS_INT variables, which is not true on typical 32-bit hosts.
10585 The code messed up by falsely reporting buffer overflow in cases
10586 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10587 when "big" contains more than 2**29 bytes, even though this
10588 inserts just one byte and does not overflow the buffer.
10589 (Finsert_file_contents): Store file offsets as off_t
10590 values, not as EMACS_INT values. Check for overflow when
10591 converting between EMACS_INT and off_t. When checking for
10592 buffer overflow or for overlap, take the offsets into account.
10593 Don't use EMACS_INT for small values where int suffices.
10594 When checking for overlap, fix a typo: ZV was used where
10595 ZV_BYTE was intended.
10596 (Fwrite_region): Don't assume off_t fits into 'long'.
10597 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10599 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10601 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10603 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10605 sprintf-related integer and memory overflow issues (Bug#9412).
10607 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10608 (esprintf, exprintf, evxprintf): New functions.
10609 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10610 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10611 (modify_event_symbol): Do not assume that the length of
10612 name_alist_or_stem is safe to alloca and fits in int.
10613 (Fexecute_extended_command): Likewise for function name and binding.
10614 (Frecursion_depth): Wrap around reliably on integer overflow.
10615 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10616 since some callers pass EMACS_INT values.
10617 (Fsingle_key_description): Don't crash if symbol name contains more
10618 than MAX_ALLOCA bytes.
10619 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10620 (get_minibuffer): Arg is now EMACS_INT, not int.
10621 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10622 (esprintf, exprintf, evxprintf): New decls.
10623 * window.h (command_loop_level, minibuf_level): Reflect API changes.
10625 * dbusbind.c (signature_cat): New function.
10626 (xd_signature, Fdbus_register_signal):
10627 Do not overrun buffer; instead, report string overflow.
10629 * dispnew.c (add_window_display_history): Don't overrun buffer.
10630 Truncate instead; this is OK since it's just a log.
10632 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10633 even if the time zone offset is outlandishly large.
10634 Don't mishandle offset == INT_MIN.
10636 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10637 when creating daemon; the previous buffer-overflow check was incorrect.
10639 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10640 which has the guts of the old verror function.
10642 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10643 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10645 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10646 (font_unparse_xlfd): Don't blindly alloca long strings.
10647 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10648 fits in int, when using sprintf. Use single snprintf to count
10649 length of string rather than counting it via multiple sprintfs;
10650 that's simpler and more reliable.
10651 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10652 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10653 sprintf, in case result does not fit in int.
10655 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10656 (fontset_from_font): Print it.
10658 * frame.c (tty_frame_count): Now printmax_t, not int.
10659 (make_terminal_frame, set_term_frame_name): Print it.
10660 (x_report_frame_params): In X, window IDs are unsigned long,
10661 not signed long, so print them as unsigned.
10662 (validate_x_resource_name): Check for implausibly long names,
10663 and don't assume name length fits in 'int'.
10664 (x_get_resource_string): Don't blindly alloca invocation name;
10665 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10668 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10669 (xg_check_special_colors, xg_set_geometry):
10670 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10672 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10673 Use esprintf, not sprintf, in case result does not fit in int.
10675 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10676 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10677 it as a large positive number.
10678 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10679 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10681 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10682 in case result does not fit in int.
10684 * print.c (float_to_string): Detect width overflow more reliably.
10685 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10686 buffer overrun. Don't assume list length fits in 'int'. Treat
10687 print length of 0 as 0, not as infinity; to be consistent with other
10688 uses of print length in this function. Don't overflow print length
10689 index. Don't assume hash table size fits in 'long', or that
10690 vectorlike size fits in 'unsigned long'.
10692 * process.c (make_process): Use printmax_t, not int, to format
10693 process-name gensyms.
10695 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10697 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10698 to avoid potential buffer overrun.
10700 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10701 if X resource line is longer than 512 bytes.
10703 * xfns.c (x_window): Make sprintf buffer a bit bigger
10704 to avoid potential buffer overrun.
10706 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10708 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10710 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10712 Integer overflow fixes for scrolling, etc.
10713 Without these, Emacs silently mishandles large integers sometimes.
10714 For example, "C-u 4294967297 M-x recenter" was treated as if
10715 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10717 * xdisp.c (try_window_id): Check Emacs fixnum range before
10718 converting to 'int'.
10720 * window.c (window_scroll_line_based, Frecenter):
10721 Check that an Emacs fixnum is in range before assigning it to 'int'.
10722 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10723 values converted from Emacs fixnums.
10724 (Frecenter): Don't wrap around a line count if it is out of 'int'
10725 range; instead, treat it as an extreme value.
10726 (Fset_window_configuration, compare_window_configurations):
10727 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10729 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10730 that can exceed INT_MAX. Check that EMACS_INT value is in range
10731 before assigning it to the (possibly-narrower) index.
10732 (match_limit): Don't assume that a fixnum can fit in 'int'.
10734 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10737 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10738 (Fvertical_motion): Don't wrap around LINES values that don't fit
10739 in 'int'. Instead, treat them as extreme values. This is good
10740 enough for windows, which can't have more than INT_MAX lines anyway.
10742 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10744 * Require libxml/parser.h to avoid compilation warning.
10746 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10748 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10749 since this reportedly can destroy thread storage.
10751 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10753 * syntax.c (find_defun_start): Update all cache variables if
10754 exiting early (Bug#9401).
10756 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10758 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10760 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10761 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10762 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10764 * term.c (tty_append_glyph): New function.
10765 (produce_stretch_glyph): Static function and its prototype deleted.
10767 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10770 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10772 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10773 when checking :margin (Bug#9390).
10774 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10775 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10776 so that the name doesn't mislead. All uses changed.
10778 2011-08-28 Johan Bockgård <bojohan@gnu.org>

10788 the first character in the line after the newline.
10790 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10792 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10793 (ccl_driver): Do not generate an out-of-range pointer.
10794 (Fccl_execute_on_string): Remove unnecessary check for
10795 integer overflow, noted by Stefan Monnier in
10796 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10797 Remove a FIXME that didn't need fixing.
10798 Simplify the newly-introduced buffer reallocation code.
10800 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10802 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10804 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10806 Integer and memory overflow issues (Bug#9196).
10808 * doc.c (get_doc_string): Rework so that
10809 get_doc_string_buffer_size is the actual buffer size, rather than
10810 being 1 less than the actual buffer size; this makes xpalloc more
10813 * image.c (x_allocate_bitmap_record, cache_image):
10814 * xselect.c (Fx_register_dnd_atom):
10815 Simplify previous changes by using xpalloc.
10817 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10818 since either will do and ptrdiff_t is convenient with xpalloc.
10820 * charset.c (charset_table_size)
10821 (struct charset_sort_data.priority): Now ptrdiff_t.
10822 (charset_compare): Don't overflow if priorities differ greatly.
10823 (Fsort_charsets): Don't assume list length fits in int.
10824 Check for size-calculation overflow when allocating sort data.
10825 (syms_of_charset): Allocate an initial charset table that is
10826 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10828 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10830 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10831 The actual value is always <= INT_MAX, and leaving it unsigned made
10832 overflow checking harder.
10834 * dispextern.h (struct glyph_matrix.rows_allocated)
10835 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10836 with xpalloc. The values are still always <= INT_MAX.
10838 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10840 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10841 (SAFE_NALLOCA): New macro.
10843 * region-cache.c (struct boundary.pos, find_cache_boundary)
10844 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10845 (set_cache_region, invalidate_region_cache)
10846 (revalidate_region_cache, know_region_cache, region_cache_forward)
10847 (region_cache_backward, pp_cache):
10848 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10849 so that ptrdiff_t * can be passed to xpalloc.
10850 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
10851 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
10852 (pp_cache): Don't assume cache_len fits in int.
10853 * region-cache.h: Adjust extern decls to match.

10856 EMACS_INT, since either will do, for xpalloc.
10858 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
10859 (xnmalloc, xnrealloc, xpalloc): New functions.
10861 * bidi.c (bidi_shelve_header_size): New constant.
10862 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
10863 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
10865 * bidi.c (bidi_cache_shrink):
10866 * buffer.c (overlays_at, overlays_in, record_overlay_string)
10868 Don't update size of array until after memory allocation succeeds,
10869 because xmalloc/xrealloc may not return.
10870 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10871 now that we have proper integer overflow checking.
10872 (record_overlay_string, overlay_strings): Catch overflows when
10873 calculating size of overlay_str_buf.
10875 * callproc.c (Fcall_process): Check for size overflow when
10876 calculating size of args2.
10877 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
10878 Normally we prefer signed values, but sticking with ptrdiff_t would
10879 require adding more-complicated checks.
10881 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10882 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
10883 Redo buffer-overflow calculations to avoid integer overflow.
10884 Add a FIXME comment where memory seems to be over-allocated.
10886 * character.c (Fstring): Check for size-calculation overflow.
10888 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
10889 unnecessary integer overflow. Check for size overflow.
10890 (encode_coding_object): Don't update size until xmalloc succeeds.
10892 * composite.c (get_composition_id): Check for overflow in glyph
10893 length calculations.
10895 Integer and memory overflow fixes for display code.
10896 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
10897 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)

10910 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
10911 (get_doc_string): Check for size calculation overflow.
10912 Don't update size until allocation succeeds.
10913 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not

10919 (message_length): Now ptrdiff_t, not int.
10920 (Fmessage_box): Don't update size until allocation succeeds.
10921 Don't assume message length fits in int.
10922 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10924 * emacs.c (main): Do not reallocate argv, since there is a null at
10925 the end that can be overwritten, and this way there's no need to
10926 worry about size-calculation overflow.
10927 (sort_args): Check for size-calculation overflow.
10929 * eval.c (init_eval_once, grow_specpdl): Don't update size until
10931 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
10933 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
10934 (x_set_scroll_bar_width, x_figure_window_size):
10935 Check for integer overflow.
10936 (x_set_alpha): Do not assume XINT fits in int.
10938 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10939 This is for the members text_lines, text_cols, total_lines, total_cols,
10940 where the system imposes an 'int' limit.
10942 * fringe.c (Fdefine_fringe_bitmap):
10943 Don't update size until alloc works.
10945 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
10946 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
10948 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
10949 Check for size-calculation overflow.
10950 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10951 do, as we prefer signed integers.
10952 (id_to_widget.max_size, id_to_widget.used)
10953 (xg_store_widget_in_map, xg_remove_widget_from_map)
10954 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
10955 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
10956 Use and return ptrdiff_t, not int.
10957 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
10958 * gtkutil.h: Change prototypes to match the above.
10960 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
10961 are duplicate now that they've been promoted to lisp.h.
10962 (x_allocate_bitmap_record, x_alloc_image_color)
10963 (make_image_cache, cache_image, xpm_load):

10977 calculations. Don't update size until allocation succeeds.
10978 Redo calculations to avoid overflow.

11007 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
11008 for command line length. Do not attempt to address one before the
11009 beginning of an array, as that's not portable.
11011 * term.c (max_frame_lines): Remove; unused.
11012 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
11014 (encode_terminal_code, calculate_costs): Check for size

11037 Use ptrdiff_t, not int, for sizes.
11038 (Finternal_make_lisp_face, cache_face):
11039 Check for size calculation overflow.
11040 (cache_face): Treat size calculation overflows as if they were
11041 memory exhaustion (the usual treatment), rather than aborting.
11043 * xfns.c (x_encode_text, x_set_name_internal)
11044 (Fx_change_window_property): Use ptrdiff_t, not int, to count
11045 sizes, since they can exceed INT_MAX in size. Check for size

11049 (xg_select): Check for size calculation overflow.
11050 Don't update size until alloc done.
11052 * xrdb.c (get_environ_db): Don't assume path length fits in int,
11053 as sprintf is limited to int lengths.
11055 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
11056 (X_LONG_MIN): New macros.
11057 Use them to make the following changes clearer.
11058 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
11059 This change doesn't affect the value now, but it may help remind
11060 future maintainers not to raise the value too much later.
11061 (SELECTION_QUANTUM): Remove, replacing with ...
11062 (selection_quantum): ... new function, which avoids overflow.
11064 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
11065 assumption that selection length fits in 'int'.

11078 (lisp_data_to_selection_data, x_property_data_to_lisp):

11082 Don't store size until memory allocation succeeds.
11083 (x_get_window_property): Plug memory leak on memory exhaustion.
11084 Don't double-block input; malloc is safe here. Don't assume 2**34
11085 - 4 fits in unsigned long. Add an xassert to check
11086 XGetWindowProperty overflow. Be more careful about overflow
11087 calculations, and distinguish size from memory overflow better.
11088 (receive_incremental_selection): When tracing, don't assume
11089 unsigned int is less than INT_MAX.
11090 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
11091 harmful) conversions of unsigned short to int.
11092 (lisp_data_to_selection_data): Don't assume that integers
11093 in the range -65535 through -1 fit in an X unsigned short.
11094 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
11095 result parameters unless successful. Rely on cons_to_unsigned
11096 to report problems with elements; the old code wasn't right anyway.
11097 (x_check_property_data): Check for int overflow; we cannot use
11098 a wider type due to X limits.
11099 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

11131 * lisp.h (hash_lookup, hash_put):
11132 * minibuf.c (Ftest_completion):
11133 Use ptrdiff_t for hash table indexes, not int (which is too
11134 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
11135 32-bit --with-wide-int hosts).
11137 * charset.c (Fdefine_charset_internal): Check for integer overflow.
11138 Add a FIXME comment about memory leaks.
11139 (syms_of_charset): Don't assume xmalloc returns.

11146 with outlandish widths.
11147 * character.h (sanitize_tab_width): Rename from sanitize_width,
11148 now that we have two such functions. All uses changed.

11169 exceed limits imposed by XClientMessageEvent, as well as the usual
11170 ptrdiff_t and size_t limits.
11172 * keyboard.c: Overflow, signedness and related fixes.
11173 (make_lispy_movement): Use same integer type in forward decl
11174 that is used in the definition.
11175 (read_key_sequence, keyremap_step):
11176 Change bufsize argument back to int, undoing my 2011-03-30 change.
11177 We prefer signed types, and int is wide enough here.
11178 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
11179 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
11180 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
11181 length, not size_t. Use ptrdiff_t for index, not int.
11182 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
11183 possibility of integer overflow.
11185 Overflow, signedness and related fixes for images.

11211 Prefer int to unsigned where either will do.
11212 (tiff_handler): New function, combining the cores of the
11213 old tiff_error_handler and tiff_warning_handler.
11214 This function is rewritten to use vsnprintf and thereby avoid
11215 stack buffer overflows. It uses only the features of vsnprintf
11216 that are common to both POSIX and native Microsoft.
11217 (tiff_error_handler, tiff_warning_handler): Use it.
11218 (tiff_load, gif_load, imagemagick_load_image):
11219 Don't assume :index value fits in 'int'.
11220 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
11221 (imagemagick_load_image): Check that crop parameters fit into
11222 the integer types that MagickCropImage accepts. Don't assume
11223 Vimagemagick_render_type has a nonnegative value. Don't assume
11224 size_t fits in 'long'.
11225 (gs_load): Use printmax_t to print the widest integers possible.
11226 Check for integer overflow when computing image height and width.

11239 (handle_single_display_spec): If the display spec is of the form
11240 `(space ...)', and specifies display in the text area, return 2
11242 (try_cursor_movement): Check for the need to scroll more
11243 accurately, and prefer exact match for point under bidi.
11244 Don't advance `row' beyond the last row of the window.
11246 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
11247 into disp_prop; all users changed.

11265 positioning on the newline at EOL of R2L text within L2R
11266 paragraph, and vice versa.
11267 (try_cursor_movement): Check continued rows, in addition to
11268 continuation rows. Fixes unwarranted scroll when point enters a
11269 continued line of R2L text within an L2R paragraph, or vice versa.
11270 (cursor_row_p): Consider the case of point being equal to
11271 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
11272 from the end of a short line to the beginning of a continued line
11273 of R2L text within L2R paragraph.

11297 * xdisp.c (redisplay_window): When computing centering_position,
11298 account for the height of the header line. (Bug#8874)
11300 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
11301 instead of CHAR_TO_BYTE. Fixes a crash when a completion
11302 candidate is selected by the mouse, and that candidate has a
11303 composed character under the mouse.
11305 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
11306 coordinates reported by pos-visible-in-window-p for a composed
11307 character in column zero.
11309 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

11316 consider it a hit if to_charpos is anywhere in the range of the
11317 composed buffer positions.
11319 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
11321 * image.c (gif_load): Don't assume that each subimage has the same
11322 dimensions as the base image. Handle disposal method that is
11323 "undefined" by the gif spec (Bug#9335).
11325 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
11327 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

11332 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
11333 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
11334 from an Org mode buffer to a Speedbar frame.
11336 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
11337 a composition, take its buffer position from IT->cmp_it.charpos.
11338 Fixes cursor positioning at the beginning of a line that begins
11339 with a composed character.
11341 2011-08-18 Eli Zaretskii <eliz@gnu.org>
11343 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
11344 character bidirectional type, use STRONG_L instead. Fixes crashes
11345 in a buffer produced by `describe-categories'.
11347 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
11348 members before the level stack, so they would be saved and
11349 restored when copying iterator state. Fixes incorrect reordering
11350 around TABs covered by display properties.
11352 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

11440 * nsterm.m (sendEvent): If event is NSApplicationDefined and
11441 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
11442 the event loop (Bug#7276).

11468 (Fnetwork_interface_list): Allocate in increments of bytes instead
11469 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
11470 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct

11484 entry. Force push_it to save on the stack the current
11485 buffer/string position, to be restored by pop_it. Fix flags in
11486 the iterator structure wrt the object coming from a display
11487 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
11488 properties. (Bug#9284)

11681 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11683 Implement strike-through and overline on NextStep (Bug#8863).
11685 * nsfont.m (nsfont_open): Use underline position provided by font,
11686 instead of hard-coded value of 2.
11687 (nsfont_draw): Call ns_draw_text_decoration instead.
11689 * nsterm.h: Add declaration for ns_draw_text_decoration.
11691 * nsterm.m (ns_draw_text_decoration): New function for drawing
11692 underline, overline, and strike-through.
11693 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
11694 ns_draw_text_decoration. Change treatment of cursor drawing to
11695 accommodate underlining, etc.
11697 2011-07-28 Eli Zaretskii <eliz@gnu.org>
11699 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
11702 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11704 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11705 Without this fix, if a signal arrives just after memory fills up,
11706 'malloc' might be invoked reentrantly.
11708 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11709 In other words, assume that every image size is allowed, on non-X
11710 hosts. This assumption is probably wrong, but it lets Emacs compile.
11712 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11714 * regex.c (re_iswctype): Convert return values to boolean.
11716 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
11718 * xdisp.c (compute_display_string_pos): Don't use cached display
11719 string position if the buffer had its restriction changed.
11722 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11724 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11726 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11728 Integer signedness and overflow and related fixes. (Bug#9079)
11730 * bidi.c: Integer size and overflow fixes.
11731 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
11732 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
11733 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11734 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11735 (bidi_find_other_level_edge):
11736 Use ptrdiff_t instead of EMACS_INT where either will do.
11737 This works better on 32-bit hosts configured --with-wide-int.
11738 (bidi_cache_ensure_space): Check for size-calculation overflow.
11739 Use % rather than repeated addition, for better worst-case speed.
11740 Don't set bidi_cache_size until after xrealloc returns, because it
11742 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11743 (bidi_cache_ensure_space): Also check that the bidi cache size
11744 does not exceed that of the largest Lisp string or buffer. See Eli
11745 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11747 * alloc.c (__malloc_size_t): Remove.
11748 All uses replaced by size_t. See Andreas Schwab's note
11749 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11751 * image.c: Improve checking for integer overflow.
11752 (check_image_size): Assume that f is nonnull, since
11753 it is always nonnull in practice. This is one less thing to
11754 worry about when checking for integer overflow later.
11755 (x_check_image_size): New function, which checks for integer
11756 overflow issues inside X.
11757 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11758 This removes the need for a memory_full check.
11759 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11760 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11761 (xbm_read_bitmap_data): Change locals back to 'int', since
11762 their values must fit in 'int'.
11763 (xpm_load_image, png_load, tiff_load):
11764 Invoke x_create_x_image_and_pixmap earlier,
11765 to avoid much needless work if the image is too large.
11766 (tiff_load): Treat overly large images as if
11767 x_create_x_image_and_pixmap failed, not as malloc failures.
11768 (gs_load): Use x_check_image_size.
11770 * gtkutil.c: Omit integer casts.
11771 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11772 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11774 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11776 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11777 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11778 would wrongly return t on a 64-bit host.
11780 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11781 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11782 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11783 and therefore cause GCC to emit a bogus diagnostic in some cases.
11785 * image.c: Integer signedness and overflow and related fixes.
11786 This is not an exhaustive set of fixes, but it's time to
11787 record what I've got.
11788 (lookup_pixel_color, check_image_size): Remove redundant decls.
11789 (check_image_size): Don't assume that arbitrary EMACS_INT values
11790 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11791 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11792 (tiff_load, imagemagick_load_image):
11793 Check for overflow in size calculations.
11794 (x_create_x_image_and_pixmap): Remove unnecessary test for
11795 xmalloc returning NULL; that can't happen.
11796 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11797 (xpm_color_bucket): Use better integer hashing function.
11798 (xpm_cache_color): Don't possibly over-allocate memory.
11799 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11800 (gif_memory_source):
11801 Use ptrdiff_t, not int or size_t, to record sizes.
11802 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11803 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11804 either works, as we prefer signed integers.
11805 (tiff_read_from_memory, tiff_write_from_memory):
11806 Return tsize_t, not size_t, since that's what the TIFF API wants.
11807 (tiff_read_from_memory): Don't fail simply because the read would
11808 go past EOF; instead, return a short read.
11809 (tiff_load): Omit no-longer-needed casts.
11810 (Fimagemagick_types): Don't assume size fits into 'int'.
11812 Improve hashing quality when configured --with-wide-int.
11813 * fns.c (hash_string): New function, taken from sxhash_string.
11814 Do not discard information about ASCII character case; this
11815 discarding is no longer needed.
11816 (sxhash-string): Use it. Change sig to match it. Caller changed.
11817 * lisp.h: Declare it.
11818 * lread.c (hash_string): Remove, since we now use fns.c's version.
11819 The fns.c version returns a wider integer if --with-wide-int is
11820 specified, so this should help the quality of the hashing a bit.
11822 * emacs.c: Integer overflow minor fix.
11823 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11824 Define only if GNU_LINUX.
11825 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11827 * dispnew.c: Integer signedness and overflow fixes.
11828 Remove unnecessary forward decls, that were a maintenance hassle.
11829 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11831 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11832 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11833 (prepare_desired_row, line_draw_cost):
11834 Use int, not unsigned, where either works.
11835 (save_current_matrix, restore_current_matrix):
11836 Use ptrdiff_t, not size_t, where either works.
11837 (init_display): Check for overflow more accurately, and without
11838 relying on undefined behavior.
11840 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11841 Remove, replacing with the new symbols in lisp.h. All uses changed.
11842 * fileio.c (make_temp_name):
11843 * filelock.c (lock_file_1, lock_file):
11844 * xdisp.c (message_dolog):
11845 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11846 Use pMd etc. instead.
11847 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11848 replacing the pWIDE etc. symbols removed from editfns.c.
11850 * keyboard.h (num_input_events): Now uintmax_t.
11851 This is (very slightly) less likely to mess up due to wraparound.
11854 * buffer.c: Integer signedness fixes.
11855 (alloc_buffer_text, enlarge_buffer_text):
11856 Use ptrdiff_t rather than size_t when either will do, as we prefer
11859 * alloc.c: Integer signedness and overflow fixes.
11860 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11861 (__malloc_size_t): Default to size_t, not to int.
11862 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11863 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11864 Prefer ptrdiff_t to size_t when either would do, as we prefer
11866 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11867 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11868 Now const. Initialize with values that are in range even if char
11870 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11871 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11872 These functions do the right thing with sizes > 2**32.
11873 (check_depth): Now ptrdiff_t, not int.
11874 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11875 Adjust to new way of storing sizes. Check for size overflow bugs
11877 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11878 slightly wrong anyway, as it missed one instance of
11879 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11880 (refill_memory_reserve): Omit needless cast to size_t.
11881 (mark_object_loop_halt): Mark as externally visible.
11883 * xselect.c: Integer signedness and overflow fixes.
11884 (Fx_register_dnd_atom, x_handle_dnd_message):
11885 Use ptrdiff_t, not size_t, since we prefer signed.
11886 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11887 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11888 x_dnd_atoms_size and x_dnd_atoms_length.
11890 * doprnt.c: Prefer signed to unsigned when either works.
11892 * doprnt.c (doprnt):
11894 * xdisp.c (vmessage):
11895 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11896 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11897 prefer signed arithmetic to avoid comparison confusion.
11898 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11899 but is a bit tricky.
11901 Assume freestanding C89 headers, string.h, stdlib.h.
11902 * data.c, doprnt.c, floatfns.c, print.c:
11903 Include float.h unconditionally.
11904 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11905 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11906 * regex.c: Likewise for stddef.h, string.h.
11907 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11908 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11909 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11910 (STDC_HEADERS): Remove obsolete defines.
11911 * sysdep.c: Include limits.h unconditionally.
11913 Assume support for memcmp, memcpy, memmove, memset.
11914 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11915 * regex.c (memcmp, memcpy):
11916 Remove; we assume C89 now.
11918 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11919 (__malloc_safe_bcopy): Remove; no longer needed.
11921 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11922 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11923 well either way, and we prefer signed to unsigned.
11925 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11927 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11928 closes the connection while we're reading (bug#9182).
11930 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11932 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11933 are specified (Bug#9168).
11935 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11937 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11938 Found by GCC static checking and --with-wide-int on a 32-bit host.
11940 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11942 * xdisp.c (compute_display_string_pos): Fix logic of caching
11943 previous display string position. Initialize cached_prev_pos to
11944 -1. Fixes slow-down at the beginning of a buffer.
11946 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11948 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11949 for attrs[LFACE_FONTSET_INDEX].
11951 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11953 * xml.c (parse_region): Remove unused local
11954 that was recently introduced.
11956 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11958 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11959 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11961 * xdisp.c (move_it_in_display_line_to): Record the best matching
11962 position for TO_CHARPOS while scanning the line, and restore it on
11963 exit if none of the characters scanned was an exact match.
11964 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11965 when exact match is impossible due to invisible text, and the
11966 lines are truncated.
11968 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11970 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11973 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11975 Fix a significant slow-down of cursor motion with C-n, C-p,
11976 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11977 auto-repeat under bidi redisplay in fontified buffers.
11978 * xdisp.c (compute_stop_pos_backwards): New function.
11979 (next_element_from_buffer): Call compute_stop_pos_backwards to
11980 find a suitable prev_stop when we find ourselves before
11982 (reseat): Don't look for prev_stop, as that could mean a very long
11984 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11985 <cached_disp_overlay_modiff>: Cache for last found display string
11987 (compute_display_string_pos): Return the cached position if asked
11988 about the same buffer in the same area of character positions, and
11989 the buffer wasn't changed since the time the display string
11990 position was cached.
11992 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11994 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11995 is an integer, which is important for empty lines. (Bug#9149)
11997 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11999 * frame.c (Fmodify_frame_parameters): In tty case, update the
12000 default face if necessary (Bug#4238).
12002 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
12004 * editfns.c (Fstring_to_char): No need to explain what a character
12005 is in the docstring (Bug#6576).
12007 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12009 * xml.c (parse_region): Make sure we always return a tree.
12011 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
12013 * xml.c (parse_region): If a document contains only comments,
12016 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12018 * xml.c (make_dom): Return comments, too.
12020 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
12023 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
12024 and the surrounding thread.
12025 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
12026 rather than fgets, and retry after EINTR. Otherwise, 'emacs
12027 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
12029 * s/openbsd.h (BROKEN_SIGIO): Define.
12030 * unexelf.c (unexec) [__OpenBSD__]:
12031 Don't update the .mdebug section of the Alpha COFF symbol table.
12033 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12035 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
12038 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
12040 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
12041 This fixes some race conditions on the permissions of any newly
12044 * alloc.c (valid_pointer_p): Use pipe, not open.
12045 This fixes some permissions issues when debugging.
12047 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
12048 If fchown fails to set both uid and gid, try to set just gid,
12049 as that is sometimes allowed. Adjust the file's mode to eliminate
12050 setuid or setgid bits that are inappropriate if fchown fails.
12052 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
12054 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
12055 to compare Lisp_Objects.
12056 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
12057 global_gnutls_log_level, don't mistake it for a Lisp_Object.
12058 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
12060 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
12062 * lread.c (read_integer): Unread even EOF character.
12063 (read1): Likewise. Properly record start position of symbol.
12065 * lread.c (read1): Read `#:' as empty uninterned symbol if no
12066 symbol character follows.
12068 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
12070 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
12071 This works around a problem with the previous change to Fcopy_file.
12072 Recent glibc declares fchown with __attribute__((warn_unused_result)),
12073 and without this change, GCC might complain about discarding
12074 fchown's return value.
12076 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
12078 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
12080 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
12082 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
12084 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
12086 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
12087 it's used from the C level.
12089 * process.c: Use the same condition for POLL_FOR_INPUT in both
12090 keyboard.c and process.c (bug#1858).
12092 2011-07-09 Lawrence Mitchell <wence@gmx.li>
12094 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
12095 (Fgnutls_boot): Use it.
12097 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
12099 * doc.c (Fsubstitute_command_keys): Revert last change.
12101 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
12103 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
12104 quotes the next character, and doesn't affect other longer
12105 sequences (bug#8935).
12107 * lread.c (syms_of_lread): Clarify that is isn't only
12108 `eval-buffer' and `eval-defun' that's affected by
12109 `lexical-binding' (bug#8460).
12111 2011-07-15 Eli Zaretskii <eliz@gnu.org>
12113 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
12114 bidi redisplay when a line includes both an image and is truncated.
12116 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
12118 Fix minor problems found by static checking.
12119 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
12120 (elsz): Now a signed constant, not a size_t var. We prefer signed

12654 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

12691 Random fixes. E.g., (random) never returned negative values.
12692 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
12693 subseconds part to the entropy, as that's a bit more random.
12694 Prefer signed to unsigned, since the signedness doesn't matter and
12695 in general we prefer signed. When given a limit, use a
12696 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12697 latter isn't right if USE_2_TAGS_FOR_INTS.
12698 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12699 not 0..VALMASK. Don't discard "excess" bits that random () returns.

12716 * buffer.c (Foverlay_put): Say what the return value is
12719 * fileio.c (barf_or_query_if_file_exists): Check first if the file

12723 error be more correct.
12725 * fns.c (Frequire): Remove the mention of the .gz files, since

12739 Qgnutls_bootprop_verify_error (which is no longer used).
12741 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
12742 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
12743 Also (re)move comments that are misplaced or no longer relevant.

12844 * eval.c (struct backtrace): Simplify and port the data structure.
12845 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12846 signed bit field, as this assumption is not portable and it makes
12847 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12848 "char debug_on_exit : 1" as this is not portable either; instead,
12849 use the portable "unsigned int debug_on_exit : 1". Remove unused
12850 member evalargs. Remove obsolete comments about cc bombing out.
12852 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

13006 * xmenu.c (syms_of_xmenu):
13007 * xsettings.c (syms_of_xsettings):
13008 * xterm.c (syms_of_xterm): Use DEFSYM.
13010 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
13012 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
13014 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
13016 Integer and buffer overflow fixes (Bug#8873).
13018 * print.c (printchar, strout): Check for string overflow.
13019 (PRINTPREPARE, printchar, strout):
13020 Don't set size unless allocation succeeds.
13022 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
13023 for sizes. Check for string overflow more accurately.
13024 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
13026 * macros.c: Integer and buffer overflow fixes.
13027 * keyboard.h (struct keyboard.kbd_macro_bufsize):
13028 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
13029 Use ptrdiff_t, not int, for sizes.
13030 Don't increment bufsize until after realloc succeeds.
13031 Check for size-calculation overflow.
13032 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
13034 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
13036 * lread.c: Integer overflow fixes.
13037 (read_integer): Radix is now EMACS_INT, not int,
13038 to improve quality of diagnostics for out-of-range radices.
13039 Calculate buffer size correctly for out-of-range radices.
13040 (read1): Check for integer overflow in radices, and in
13041 read-circle numbers.
13042 (read_escape): Avoid int overflow.
13043 (Fload, openp, read_buffer_size, read1)
13044 (substitute_object_recurse, read_vector, read_list, map_obarray):
13045 Use ptrdiff_t, not int, for sizes.
13046 (read1): Use EMACS_INT, not int, for sizes.
13047 Check for size overflow.
13049 * image.c (cache_image): Check for size arithmetic overflow.
13051 * lread.c: Integer overflow issues.
13052 (saved_doc_string_size, saved_doc_string_length)
13053 (prev_saved_doc_string_size, prev_saved_doc_string_length):
13054 Now ptrdiff_t, not int.

13056 out-of-range doc string lengths.
13057 (read_list): Don't assume file position fits in int.
13058 (read_escape): Check for hex character overflow.
13060 2011-06-22 Leo Liu <sdl.web@gmail.com>
13062 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
13063 Move to minibuffer.el.
13065 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13067 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
13068 The following patches are for when GLYPH_DEBUG && !XASSERT.
13069 * dispextern.h (trace_redisplay_p, dump_glyph_string):
13070 * dispnew.c (flush_stdout):
13071 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
13072 Mark as externally visible.
13073 * dispnew.c (check_window_matrix_pointers): Now static.
13074 * dispnew.c (window_to_frame_vpos):
13075 * xfns.c (unwind_create_frame):
13076 * xterm.c (x_check_font): Remove unused local.
13077 * scroll.c (CHECK_BOUNDS):
13078 * xfaces.c (cache_fache): Rename local to avoid shadowing.
13079 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
13080 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
13081 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
13082 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
13084 (debug_method_add): Use va_list and vsprintf rather than relying
13085 on undefined behavior with wrong number of arguments.
13086 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
13087 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
13088 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
13089 since we're not interested in debugging glyphs with old libraries.
13090 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
13091 GCC 4.6.0's static checking.
13093 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13095 Integer overflow and signedness fixes (Bug#8873).
13096 A few related buffer overrun fixes, too.

13104 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
13105 (x_create_bitmap_from_xpm_data):
13106 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
13107 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
13109 * xfaces.c (load_pixmap):
13110 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
13111 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
13112 (.bitmaps_last, struct x_output.icon_bitmap):
13113 Use ptrdiff_t, not int, for bitmap indexes.
13114 (x_allocate_bitmap_record): Check for size overflow.
13115 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
13117 Use ptrdiff_t, not int, for overlay counts.
13118 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
13119 * editfns.c (overlays_around, get_pos_property):
13120 * textprop.c (get_char_property_and_overlay):
13121 * xdisp.c (next_overlay_change, note_mouse_highlight):
13122 * xfaces.c (face_at_buffer_position):
13123 * buffer.c (OVERLAY_COUNT_MAX): New macro.
13124 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
13125 (Fnext_overlay_change, Fprevious_overlay_change)
13126 (mouse_face_overlay_overlaps, Foverlays_in):
13127 Use ptrdiff_t, not int, for sizes.
13128 (overlays_at, overlays_in): Check for size-calculation overflow.
13130 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
13132 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
13133 (x_session_initialize): Do not assume string length fits in int.
13135 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
13136 This is unlikely, but can occur if DPI is outlandish.
13138 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
13139 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
13141 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
13142 * xrdb.c (magic_file_p, search_magic_path):
13143 Omit last arg SUFFIX; it was always 0. All callers changed.
13144 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
13146 * xfont.c (xfont_match): Avoid need for strlen.
13148 * xfns.c: Don't assume strlen fits in int.
13149 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
13151 * xdisp.c (message_log_check_duplicate): Return intmax_t,
13152 not unsigned long, as we prefer signed integers. All callers changed.
13153 Detect integer overflow in repeat count.
13154 (message_dolog): Don't assume print length fits in 39 bytes.
13155 (display_mode_element): Don't assume strlen fits in int.
13157 * termcap.c: Don't assume sizes fit in int and never overflow.
13158 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
13159 (gobble_line): Check for size-calculation overflow.
13161 * minibuf.c (Fread_buffer):
13162 * lread.c (intern, intern_c_string):
13163 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
13164 Don't assume string length fits in int.
13166 * keyboard.c (parse_tool_bar_item):
13167 * gtkutil.c (style_changed_cb): Avoid need for strlen.
13169 * font.c: Don't assume string length fits in int.
13170 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
13171 Use ptrdiff_t, not int.
13172 (font_intern_prop): Don't assume string length fits in int.
13173 Don't assume integer property fits in fixnum.
13174 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
13176 * filelock.c: Fix some buffer overrun and integer overflow issues.
13177 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
13178 Reformulate so as not to need the command string.
13179 Invoke gzip -cd rather than gunzip, as it's more portable.
13180 (lock_info_type, lock_file_1, lock_file):
13181 Don't assume pid_t and time_t fit in unsigned long.
13182 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
13183 (current_lock_owner): Prefer signed type for sizes.
13184 Use memcpy, not strncpy, where memcpy is what is really wanted.
13185 Don't assume (via atoi) that time_t and pid_t fit in int.
13186 Check for time_t and/or pid_t out of range, e.g., via a network share.
13187 Don't alloca where an auto var works fine.
13189 * fileio.c: Fix some integer overflow issues.
13190 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
13191 Don't assume string length fits in int.
13192 (directory_file_name): Don't assume string length fits in long.
13193 (make_temp_name): Don't assume pid fits in int, or that its print
13194 length is less than 20.
13196 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
13198 * coding.c (make_subsidiaries): Don't assume string length fits in int.
13200 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
13202 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
13203 We prefer signed integers, even for size calculations.
13205 * emacs.c: Don't assume string length fits in 'int'.
13206 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
13207 (main): Don't invoke strlen when not needed.
13209 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
13210 (XD_DEBUG_MESSAGE): Don't waste a byte.
13212 * callproc.c (getenv_internal_1, getenv_internal)
13213 (Fgetenv_internal):
13214 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
13216 * lread.c (invalid_syntax): Omit length argument.
13217 All uses changed. This doesn't fix a bug, but it simplifies the
13218 code away from its former Hollerith-constant appearance, and it's
13219 one less 'int' to worry about when looking at integer-overflow issues.
13220 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
13222 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
13223 This didn't break anything, but it didn't help either.
13224 It's confusing to put a bogus integer in a place where the actual
13225 value does not matter.
13226 (LIST_END_P): Remove unused macro and its bogus comment.
13227 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
13229 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
13230 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
13232 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
13233 We prefer signed types, and the value cannot exceed the EMACS_INT
13234 range anyway (because otherwise the length would not be representable).
13235 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
13236 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
13237 This avoids a GCC warning when WIDE_EMACS_INT.
13239 * indent.c (sane_tab_width): New function.
13240 (current_column, scan_for_column, Findent_to, position_indentation)
13241 (compute_motion): Use it. This is just for clarity.
13242 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
13244 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
13246 * lisp.h (lint_assume): New macro.
13247 * composite.c (composition_gstring_put_cache):
13248 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
13250 * editfns.c, insdel.c:
13251 Omit unnecessary forward decls, to simplify future changes.
13253 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
13255 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
13257 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
13258 Use much-faster test for byte-length change.
13259 Don't assume string byte-length fits in 'int'.
13260 Check that character arg fits in 'int'.
13261 (mapcar1): Declare byte as byte, for clarity.
13263 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
13265 * fns.c (concat): Catch string overflow earlier.
13266 Do not rely on integer wraparound.
13268 * dispextern.h (struct it.overlay_strings_charpos)
13269 (struct it.selective): Now EMACS_INT, not int.
13270 * xdisp.c (forward_to_next_line_start)
13271 (back_to_previous_visible_line_start)
13272 (reseat_at_next_visible_line_start, next_element_from_buffer):
13273 Don't arbitrarily truncate the value of 'selective' to int.
13275 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
13277 * composite.c: Don't truncate sizes to 'int'.
13278 (composition_gstring_p, composition_reseat_it)
13279 (composition_adjust_point): Use EMACS_INT, not int.
13280 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
13281 not EMACS_UINT, for indexes.
13283 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
13285 * buffer.c: Include <verify.h>.
13286 (struct sortvec.priority, struct sortstr.priority):
13287 Now EMACS_INT, not int.
13288 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
13289 (struct sortstr.size, record_overlay_string)
13290 (struct sortstrlist.size, struct sortlist.used):
13291 Don't truncate size to int.
13292 (record_overlay_string): Check for size-calculation overflow.
13293 (init_buffer_once): Check at compile-time, not run-time.
13295 2011-06-22 Jim Meyering <meyering@redhat.com>
13297 Don't leak an XBM-image-sized buffer
13298 * image.c (xbm_load): Free the image buffer after using it.
13300 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
13303 * composite.c (find_automatic_composition): Omit needless 'return 0;'
13304 that Sun C diagnosed.
13305 * fns.c (secure_hash): Fix pointer signedness issue.
13306 * intervals.c (static_offset_intervals): New function.
13307 (offset_intervals): Use it.
13309 2011-06-21 Leo Liu <sdl.web@gmail.com>
13312 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
13315 * fns.c (secure_hash): Rename from crypto_hash_function and change
13316 the first arg to accept symbols.
13317 (Fsecure_hash): New primitive.
13318 (syms_of_fns): New symbols.
13320 2011-06-20 Deniz Dogan <deniz@dogan.se>
13322 * process.c (Fset_process_buffer): Clarify return value in
13325 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
13327 * dispnew.c (add_window_display_history): Use BVAR.
13329 * xdisp.c (debug_method_add): Use BVAR.
13330 (check_window_end, dump_glyph_matrix, dump_glyph)
13331 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
13333 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
13336 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
13337 check till after the cache is created in init_frame_faces.
13339 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
13341 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
13343 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
13345 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
13346 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
13347 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
13349 Improve buffer-overflow checking (Bug#8873).
13350 * fileio.c (Finsert_file_contents):
13351 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
13352 Remove the old (too-loose) buffer overflow checks.
13353 They weren't needed, since make_gap checks for buffer overflow.
13354 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
13355 The old code merely checked for Emacs fixnum overflow, and relied
13356 on undefined (wraparound) behavior. The new code avoids undefined
13357 behavior, and also checks for ptrdiff_t and/or size_t overflow.
13359 * editfns.c (Finsert_char): Don't dump core with very negative counts.
13360 Tune. Don't use wider integers than needed. Don't use alloca.
13361 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
13363 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
13365 * insdel.c, lisp.h (buffer_overflow): New function.
13366 (insert_from_buffer_1, replace_range, replace_range_2):
13367 * insdel.c (make_gap_larger):
13368 * editfns.c (Finsert_char):
13369 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
13371 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
13373 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
13375 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
13377 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
13378 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
13380 * fileio.c: Don't assume EMACS_INT fits in off_t.
13381 (emacs_lseek): New static function.
13382 (Finsert_file_contents, Fwrite_region): Use it.
13383 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
13385 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
13387 * fns.c: Don't overflow int when computing a list length.
13388 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
13389 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
13390 truncation on 64-bit hosts. Check for QUIT every
13391 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
13392 faster and is responsive enough.
13393 (Flength): Report an error instead of overflowing an integer.
13394 (Fsafe_length): Return a float if the value is not representable
13395 as a fixnum. This shouldn't happen except in contrived situations.
13396 (Fnthcdr, Fsort): Don't assume list length fits in int.
13397 (Fcopy_sequence): Don't assume vector length fits in int.
13399 * alloc.c: Check that resized vectors' lengths fit in fixnums.
13400 (header_size, word_size): New constants.
13401 (allocate_vectorlike): Don't check size overflow here.
13402 (allocate_vector): Check it here instead, since this is the only
13403 caller of allocate_vectorlike that could cause overflow.
13404 Check that the new vector's length is representable as a fixnum.
13406 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
13407 The previous code was bogus. For example, next_almost_prime (32)
13408 returned 39, which is undesirable as it is a multiple of 3; and
13409 next_almost_prime (24) returned 25, which is a multiple of 5 so
13410 why was the code bothering to check for multiples of 7?
13412 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
13414 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
13416 Variadic C functions now count arguments with ptrdiff_t.
13417 This partly undoes my 2011-03-30 change, which replaced int with size_t.
13418 Back then I didn't know that the Emacs coding style prefers signed int.
13419 Also, in the meantime I found a few more instances where arguments
13420 were being counted with int, which may truncate counts on 64-bit
13421 machines, or EMACS_INT, which may be unnecessarily wide.
13422 * lisp.h (struct Lisp_Subr.function.aMANY)
13423 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
13424 Arg counts are now ptrdiff_t, not size_t.
13425 All variadic functions and their callers changed accordingly.
13426 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
13427 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
13428 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
13429 * callint.c (Fcall_interactively): Check arg count for overflow,
13430 to avoid potential buffer overrun. Use signed char, not 'int',
13431 for 'varies' array, so that we needn't bother to check its size
13432 calculation for overflow.
13433 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
13434 * eval.c (apply_lambda):
13435 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
13436 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
13437 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
13439 * callint.c (Fcall_interactively): Don't use index var as event count.
13441 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
13442 * mem-limits.h (SIZE): Remove; no longer used.
13444 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
13446 Remove unnecessary casts.
13447 * xterm.c (x_term_init):
13448 * xfns.c (x_set_border_pixel):
13449 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
13450 These aren't needed now that we assume ANSI C.
13452 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
13453 It's more likely to cause problems (due to unsigned overflow)
13456 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
13458 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
13460 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
13462 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
13464 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
13466 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
13468 GLYPH_CODE_FACE returns EMACS_INT, not int.
13469 * dispextern.h (merge_faces):
13470 * xfaces.c (merge_faces):
13471 * xdisp.c (get_next_display_element, next_element_from_display_vector):
13472 Don't assume EMACS_INT fits in int.
13474 * character.h (CHAR_VALID_P): Remove unused parameter.
13475 * fontset.c, lisp.h, xdisp.c: All uses changed.
13477 * editfns.c (Ftranslate_region_internal): Omit redundant test.
13479 * fns.c (concat): Minor tuning based on overflow analysis.
13480 This doesn't fix any bugs. Use int to hold character, instead
13481 of constantly refetching from Emacs object. Use XFASTINT, not
13482 XINT, for value known to be a character. Don't bother comparing
13483 a single byte to 0400, as it's always less.
13485 * floatfns.c (Fexpt):
13486 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
13488 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
13491 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
13493 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
13494 Without this fix, on a 64-bit host (aset S 0 4294967386) would
13495 incorrectly succeed when S was a string, because 4294967386 was
13496 truncated before it was used.
13498 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13499 Otherwise, an out-of-range integer could cause undefined behavior
13502 * composite.c: Use int, not EMACS_INT, for characters.
13503 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13504 EMACS_INT, for values that are known to be in character range.
13505 This doesn't fix any bugs but is the usual style inside Emacs and
13506 may generate better code on 32-bit machines.
13508 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13509 This is for reasons similar to the recent CHAR_STRING fix.
13510 * charset.c (Fencode_char): Check that character arg is actually
13511 a character. Pass an int to ENCODE_CHAR.
13512 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13513 wider than 'int', as a compile-time check to prevent future regressions
13516 * character.c (char_string): Remove unnecessary casts.
13518 Make sure a 64-bit char is never passed to CHAR_STRING.
13519 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13520 by silently ignoring the top 32 bits, allowing some values
13521 that were far too large to be valid characters.
13522 * character.h: Include <verify.h>.
13523 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13524 arguments are no wider than unsigned, as a compile-time check
13525 to prevent future regressions in this area.
13527 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
13528 (Fsubst_char_in_region):
13530 * xdisp.c (decode_mode_spec_coding):
13531 Adjust to CHAR_STRING's new requirement.
13532 * editfns.c (Finsert_char, Fsubst_char_in_region):
13533 * fns.c (concat): Check that character args are actually
13534 characters. Without this test, these functions did the wrong
13535 thing with wildly out-of-range values on 64-bit hosts.
13537 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13538 These casts should not be needed on 32-bit hosts, either.
13539 * keyboard.c (read_char):
13540 * lread.c (Fload): Remove casts to unsigned.
13542 * lisp.h (UNSIGNED_CMP): New macro.
13543 This fixes comparison bugs on 64-bit hosts.
13544 (ASCII_CHAR_P): Use it.
13545 * casefiddle.c (casify_object):
13546 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
13547 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
13548 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
13549 * dispextern.h (FACE_FROM_ID):
13550 * keyboard.c (read_char): Use UNSIGNED_CMP.
13552 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
13553 not to EMACS_INT, to avoid GCC warning.
13555 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13557 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13558 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
13559 isn't needed on 32-bit machines.
13561 * buffer.c (Fgenerate_new_buffer_name):
13562 Use EMACS_INT for count, not int.
13563 (advance_to_char_boundary): Return EMACS_INT, not int.
13565 * data.c (Qcompiled_function): Now static.
13567 * window.c (window_body_lines): Now static.
13569 * image.c (gif_load): Rename local to avoid shadowing.
13571 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
13572 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
13573 * alloc.c (make_save_value): Integer argument is now of type
13574 ptrdiff_t, not int.
13575 (mark_object): Use ptrdiff_t, not int.
13576 * lisp.h (pD): New macro.
13577 * print.c (print_object): Use it.
13579 * alloc.c: Use EMACS_INT, not int, to count objects.
13580 (total_conses, total_markers, total_symbols, total_vector_size)
13581 (total_free_conses, total_free_markers, total_free_symbols)
13582 (total_free_floats, total_floats, total_free_intervals)
13583 (total_intervals, total_strings, total_free_strings):
13584 Now EMACS_INT, not int. All uses changed.
13585 (Fgarbage_collect): Compute overall total using a double, so that
13586 integer overflow is less likely to be a problem. Check for overflow
13587 when converting back to an integer.
13588 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
13589 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
13590 These were 'int' variables that could overflow on 64-bit hosts;
13591 they were never used, so remove them instead of repairing them.
13592 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
13593 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
13594 Previously, this ceilinged at INT_MAX, but that doesn't work on
13596 (allocate_pseudovector): Don't use EMACS_INT when int would do.
13598 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
13599 (allocate_vectorlike): Check for ptrdiff_t overflow.
13600 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13601 when a (possibly-narrower) signed value would do just as well.
13602 We prefer using signed arithmetic, to avoid comparison confusion.
13604 * alloc.c: Catch some string size overflows that we were missing.
13605 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
13606 for convenience in STRING_BYTES_MAX.
13607 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
13608 The definition here is exact; the one in lisp.h was approximate.
13609 (allocate_string_data): Check for string overflow. This catches
13610 some instances we weren't catching before. Also, it catches
13611 size_t overflow on (unusual) hosts where SIZE_MAX <= min
13612 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
13613 and ptrdiff_t and EMACS_INT are both 64 bits.
13615 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
13616 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
13617 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
13619 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
13621 * alloc.c (Fmake_string): Check for out-of-range init.
13623 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
13625 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
13627 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
13629 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
13630 xg_get_default_scrollbar_width.
13632 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
13633 (int_gtk_range_get_value): Move to the scroll bar part of the file.
13634 (style_changed_cb): Call update_theme_scrollbar_width and call
13635 x_set_scroll_bar_default_width and xg_frame_set_char_size for
13636 all frames (Bug#8505).
13637 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
13638 Call gtk_window_set_resizable if HAVE_GTK3.
13639 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
13640 and height if HAVE_GTK3 (Bug#8505).
13641 (scroll_bar_width_for_theme): New variable.
13642 (update_theme_scrollbar_width): New function.
13643 (xg_get_default_scrollbar_width): Move code to
13644 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
13645 (xg_initialize): Call update_theme_scrollbar_width.
13647 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
13649 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
13651 2011-06-12 Martin Rudalics <rudalics@gmx.at>
13653 * frame.c (make_frame): Call other_buffer_safely instead of
13656 * window.c (temp_output_buffer_show): Call display_buffer with
13657 second argument Vtemp_buffer_show_specifiers and reset latter
13658 immediately after the call.
13659 (Vtemp_buffer_show_specifiers): New variable.
13660 (auto_window_vscroll_p, next_screen_context_lines)
13661 (Vscroll_preserve_screen_position): Remove leading asterisks from
13664 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
13666 Fix minor problems found by GCC 4.6.0 static checking.

13668 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
13669 (record_buffer): Remove unused local.
13670 * frame.c (other_visible_frames, frame_buffer_list): Now static.

13682 * widgetprv.h (emacsFrameClassRec): Remove decl.
13683 * window.c (delete_deletable_window): Now returns void, since it
13684 wasn't returning anything.
13685 (compare_window_configurations): Remove unused locals.
13686 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.

13706 * window.c (delete_deletable_window): Re-add.
13707 (Fset_window_configuration): Rewrite to handle dead buffers and
13708 consequently deletable windows.
13709 (window_tree, Fwindow_tree): Remove. Supply functionality in
13711 (compare_window_configurations): Simplify code.

13844 Remove static from declaration of Qdelete_window, it's
13845 temporarily needed by Fbury_buffer.
13846 (replace_window): Don't assign orig_top_line and
13848 (Fdelete_window, delete_window): Remove. Window deletion is

13850 (window_loop): Remove DELETE_OTHER_WINDOWS case.
13851 Replace Fdelete_window calls with calls to Qdelete_window.
13852 (Fdelete_other_windows): Remove. Deleting other windows is

14257 * gnutls.c: Use Emacs's memory allocators.
14258 Without this change, the gnutls library would invoke malloc etc.
14259 directly, which causes problems on non-SYNC_INPUT hosts, and which
14260 runs afoul of improving memory_full behavior. (Bug#8761)
14261 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
14262 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
14263 xfree instead of the default malloc, realloc, free.
14264 (Fgnutls_boot): No need to check for memory allocation failure,
14265 since xmalloc does that for us.

14294 need to be updated by these changes.
14295 * fns.c (make_hash_table, maybe_resize_hash_table):
14296 Check for integer overflow with large hash tables.
14297 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
14298 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
14299 (SXHASH_REDUCE): New macro.
14300 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
14301 Use it instead of discarding useful hash info with large hash values.
14302 (sxhash_float): New function.
14303 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
14304 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
14305 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
14306 Rewrite to use FIXNUM_BITS, as this simplifies things.
14307 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
14308 Adjust signatures to match updated version of code.
14309 (consing_since_gc): Now EMACS_INT, since a single hash table can
14310 use more than INT_MAX bytes.
14312 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
14314 Make it possible to build with GCC-4.6+ -O2 -flto.
14316 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
14318 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
14320 * minibuf.c (get_minibuffer, read_minibuf_unwind):
14321 Call minibuffer-inactive-mode.
14323 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
14325 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
14326 Update dependencies.
14328 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14330 * data.c (init_data): Remove code for UTS, this system is not
14333 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14335 Don't force ./temacs to start in terminal mode.
14337 * frame.c (make_initial_frame): Initialize faces in all cases, not
14338 only when CANNOT_DUMP is defined.
14339 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
14341 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14343 * dispnew.c (add_window_display_history): Use const for the string
14344 pointer. Remove declaration, not needed.
14346 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14348 Use 'inline', not 'INLINE'.
14349 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
14350 * alloc.c, fontset.c (INLINE): Remove.
14351 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
14352 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
14353 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
14354 * gmalloc.c (register_heapinfo): Use inline unconditionally.
14355 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
14357 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14359 Make it possible to run ./temacs.
14361 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
14362 syms_of_callproc does the same thing. Remove test for
14363 "initialized", do it in the caller.
14364 * emacs.c (main): Avoid calling set_initial_environment when dumping.
14366 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
14368 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
14369 (read_minibuf): Use get_minibuffer.
14370 (syms_of_minibuf): Use DEFSYM.
14371 (Qmetadata): New var.
14372 * data.c (Qbuffer): Don't make it static.
14373 (syms_of_data): Use DEFSYM.
14375 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14377 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
14378 (CCL_CODE_MIN): New macro.
14380 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
14382 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
14384 * eval.c (Qdebug): Now static.
14385 * lisp.h (Qdebug): Remove decl. This reverts a part of the
14386 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
14387 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
14389 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14391 * image.c: Various fixes to ImageMagick code comments.
14392 (Fimagemagick_types): Doc fix.
14394 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
14396 Minor fixes prompted by GCC 4.6.0 warnings.
14398 * xselect.c (converted_selections, conversion_fail_tag): Now static.
14400 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
14401 (x_clipboard_manager_save_all): Move extern decl to ...
14402 * xterm.h: ... here, so that it can be checked for consistency.
14404 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14406 * xselect.c (x_clipboard_manager_save_frame)
14407 (x_clipboard_manager_save_all): New functions.
14408 (Fx_clipboard_manager_save): Lisp function deleted.
14410 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
14411 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
14413 * xterm.h: Update prototype.
14415 2011-05-28 William Xu <william.xwl@gmail.com>
14417 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
14418 exiting (Bug#8239).
14420 2011-05-28 Jim Meyering <meyering@redhat.com>
14422 Avoid a sign-extension bug in crypto_hash_function.
14423 * fns.c (to_uchar): Define.
14424 (crypto_hash_function): Use it to convert some newly-signed
14425 variables to unsigned, to avoid sign-extension bugs. For example,
14426 without this change, (md5 "truc") would evaluate to
14427 45723a2aff78ff4fff7fff1114760e62 rather than the expected
14428 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
14429 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
14431 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14433 Integer overflow fixes.
14435 * dbusbind.c: Serial number integer overflow fixes.
14436 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
14437 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
14438 to hold a serial number that is too large for a fixnum.
14439 (Fdbus_method_return_internal, Fdbus_method_error_internal):
14440 Check for serial numbers out of range. Decode any serial number
14441 that was so large that it became a float. (Bug#8722)
14443 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
14444 (Fdbus_call_method, Fdbus_call_method_asynchronously):
14445 Use XFASTINT rather than XUINT when numbers are nonnegative.
14446 (xd_append_arg, Fdbus_method_return_internal):
14447 (Fdbus_method_error_internal): Likewise. Also, for unsigned
14448 arguments, check that Lisp number is nonnegative, rather than
14449 silently wrapping negative numbers around. (Bug#8722)
14450 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
14453 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
14455 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
14457 ccl: Add integer overflow checks.
14458 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
14459 (IN_INT_RANGE): New macros.
14460 (ccl_driver): Use them to check for integer overflow when
14461 decoding a CCL program. Many of the new checks are whether XINT (x)
14462 fits in int; it doesn't always, on 64-bit hosts. The new version
14463 doesn't catch all possible integer overflows, but it's an
14464 improvement. (Bug#8719)
14466 * alloc.c (make_event_array): Use XINT, not XUINT.
14467 There's no need for unsigned here.
14469 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
14470 This follows up to the 2011-05-06 change that substituted uintptr_t
14471 for EMACS_INT. This case wasn't caught back then.
14473 Rework Fformat to avoid integer overflow issues.
14474 * editfns.c: Include <float.h> unconditionally, as it's everywhere
14475 now (part of C89). Include <verify.h>.
14476 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
14477 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
14478 (Fformat): Avoid the prepass trying to compute sizes; it was only
14479 approximate and thus did not catch overflow reliably. Instead, walk
14480 through the format just once, formatting and computing sizes as we go,
14481 checking for integer overflow at every step, and allocating a larger
14482 buffer as needed. Keep track separately whether the format is
14483 multibyte. Keep only the most-recently calculated precision, rather
14484 than them all. Record whether each argument has been converted to
14485 string. Use EMACS_INT, not int, for byte and char and arg counts.
14486 Support field widths and precisions larger than INT_MAX. Avoid
14487 sprintf's undefined behavior with conversion specifications such as %#d
14488 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
14489 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
14490 formatting out-of-range floating point numbers with int
14491 formats. (Bug#8668)
14493 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
14495 * data.c: Avoid integer truncation in expressions involving floats.
14496 * data.c: Include <intprops.h>.
14497 (arith_driver): When there's an integer overflow in an expression
14498 involving floating point, convert the integers to floating point
14499 so that the resulting value does not suffer from catastrophic
14500 integer truncation. For example, on a 64-bit host (* 4
14501 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14502 Do not rely on undefined behavior after integer overflow.
14504 merge count_size_as_multibyte, parse_str_to_multibyte
14505 * character.c, character.h (count_size_as_multibyte):
14506 Rename from parse_str_to_multibyte; all uses changed.
14507 Check for integer overflow.
14508 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14509 since it's now a duplicate of the other. This is more of
14510 a character than a buffer op, so better that it's in character.c.
14511 * fns.c, print.c: Adjust to above changes.
14513 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14515 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14517 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14519 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14520 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14521 (x_clipboard_manager_save): Now static.
14522 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14524 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14525 (crypto_hash_function): Now static.
14526 Fix pointer signedness problems. Avoid unnecessary initializations.
14528 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14530 * termhooks.h (Vselection_alist): Make it terminal-local.
14532 * terminal.c (create_terminal): Initialize it.
14534 * xselect.c: Support for clipboard managers.
14535 (Vselection_alist): Move to termhooks.h as terminal-local var.
14536 (LOCAL_SELECTION): New macro.
14537 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14538 (symbol_to_x_atom): Remove gratuitous arg.
14539 (x_handle_selection_request, lisp_data_to_selection_data)
14540 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14541 (x_own_selection, x_get_local_selection, x_convert_selection):
14542 New arg, specifying work frame. Use terminal-local Vselection_alist.
14543 (some_frame_on_display): Delete unused function.
14544 (Fx_own_selection_internal, Fx_get_selection_internal)
14545 (Fx_disown_selection_internal, Fx_selection_owner_p)
14546 (Fx_selection_exists_p): New optional frame arg.
14547 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14548 (x_handle_selection_clear): Don't treat other terminals with the
14549 same keyboard specially. Use the terminal-local Vselection_alist.
14550 (x_clear_frame_selections): Use Frun_hook_with_args.
14552 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14554 * xterm.h: Add support for those atoms.
14556 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14558 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14559 (converted_selections, conversion_fail_tag): New global variables.
14560 (x_selection_request_lisp_error): Free the above.
14561 (x_get_local_selection): Remove unnecessary code.
14562 (x_reply_selection_request): Args changed; handle arbitrary array
14563 of converted selections stored in converted_selections.
14564 Separate the XChangeProperty and SelectionNotify steps.
14565 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14566 (x_convert_selection): New function.
14567 (x_handle_selection_event): Simplify.
14568 (x_get_foreign_selection): Don't ignore incoming requests while
14569 waiting for an answer; this will fail when we implement
14570 SAVE_TARGETS, and seems unnecessary anyway.
14571 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14572 (Vx_sent_selection_functions): Doc fix.
14574 2011-05-26 Leo Liu <sdl.web@gmail.com>
14576 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14578 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14580 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14582 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14583 for fringe update if it has periodic bitmap.
14584 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14585 and fringe_bitmap_periodic_p.
14587 * fringe.c (get_fringe_bitmap_data): New function.
14588 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14589 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14590 row. Mark glyph row for fringe update if periodicity changed.
14592 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14593 for fringe update unless it has periodic bitmap.
14595 2011-05-25 Kenichi Handa <handa@m17n.org>
14597 * xdisp.c (get_next_display_element): Set correct it->face_id for
14598 a static composition.
14600 2011-05-24 Leo Liu <sdl.web@gmail.com>
14603 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
14605 * fns.c (crypto_hash_function, Fsha1): New function.
14606 (Fmd5): Use crypto_hash_function.
14607 (syms_of_fns): Add Ssha1.
14609 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14611 * gnutls.c: Remove unused macros.
14612 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14613 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14614 Remove macros that are defined and never used.
14615 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14617 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14619 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14620 (Fx_get_selection_internal): Minor cleanup.
14621 (Fx_own_selection_internal): Rename arguments for consistency with
14624 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14626 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
14628 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14630 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
14632 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14634 * dispnew.c (scrolling_window): Don't exclude the case that the
14635 last enabled row in the desired matrix touches the bottom boundary.
14637 2011-05-21 Glenn Morris <rgm@gnu.org>
14639 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
14640 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
14641 and add some more files.
14643 2011-05-20 Eli Zaretskii <eliz@gnu.org>
14645 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
14646 report_file_error introduced by the change from 2011-05-07.
14648 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14650 * systime.h (Time): Define only if emacs is defined.
14651 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14652 where the include path doesn't have X11/X.h by default. See
14653 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14655 2011-05-20 Kenichi Handa <handa@m17n.org>
14657 * composite.c (find_automatic_composition): Fix previous change.
14659 2011-05-20 Glenn Morris <rgm@gnu.org>
14661 * lisp.mk: New file, split from Makefile.in.
14662 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14663 (shortlisp): Remove.
14664 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14666 2011-05-19 Glenn Morris <rgm@gnu.org>
14668 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14669 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14670 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14671 (lisp): Set the order to that of loadup.el.
14672 (shortlisp): Make it a copy of $lisp.
14673 (SOME_MACHINE_LISP): Remove.
14674 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14675 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14677 2011-05-18 Kenichi Handa <handa@m17n.org>
14679 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14680 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14681 (find_automatic_composition): Mostly rewrite for efficiency.
14683 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14685 * makefile.w32-in: Update dependencies.
14687 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14689 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14690 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14692 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14694 Fix some integer overflow issues, such as string length overflow.
14696 * insdel.c (count_size_as_multibyte): Check for string overflow.
14698 * character.c (lisp_string_width): Check for string overflow.
14699 Use EMACS_INT, not int, for string indexes and lengths; in
14700 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14701 the resulting string length overflows an EMACS_INT; instead,
14702 report a string overflow if no precision given. When checking for
14703 precision exhaustion, use a check that cannot possibly have
14704 integer overflow. (Bug#8675)
14705 * character.h (lisp_string_width): Adjust to new signature.
14707 * alloc.c (string_overflow): New function.
14708 (Fmake_string): Use it. This doesn't change behavior, but saves
14709 a few bytes and will simplify future changes.
14710 * character.c (string_escape_byte8): Likewise.
14711 * lisp.h (string_overflow): New decl.
14713 Fixups, following up to the user-interface timestamp change.
14714 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14715 for UI timestamps, instead of unsigned long.
14716 * msdos.c (mouse_get_pos): Likewise.
14717 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14718 * w32gui.h (Time): Define by including "systime.h" rather than by
14719 declaring it ourselves. (Bug#8664)
14721 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14722 * image.c (clear_image_cache): Likewise.
14724 * term.c (term_mouse_position): Don't assume time_t wraparound.
14726 Be more systematic about user-interface timestamps.
14727 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14728 and sometimes 'EMACS_UINT', to represent these timestamps.
14729 This change causes it to use 'Time' uniformly, as that's what X uses.
14730 This makes the code easier to follow, and makes it easier to catch
14731 integer overflow bugs such as Bug#8664.
14732 * frame.c (Fmouse_position, Fmouse_pixel_position):
14733 Use Time, not unsigned long, for user-interface timestamps.
14734 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14735 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14736 * keyboard.h (last_event_timestamp): Likewise.
14737 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14738 * menu.h (xmenu_show): Likewise.
14739 * term.c (term_mouse_position): Likewise.
14740 * termhooks.h (struct input_event.timestamp): Likewise.
14741 (struct terminal.mouse_position_hook): Likewise.
14742 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14743 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14744 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14745 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14746 what it was before.
14747 * menu.h, termhooks.h: Include "systime.h", for Time.
14749 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14750 Don't assume that the difference between two unsigned long values
14751 can fit into an integer. At this point, we know button_down_time
14752 <= event->timestamp, so the difference must be nonnegative, so
14753 there's no need to cast the result if double-click-time is
14754 nonnegative, as it should be; check that it's nonnegative, just in
14755 case. This bug is triggered when events are more than 2**31 ms
14756 apart (about 25 days). (Bug#8664)
14758 * xselect.c (last_event_timestamp): Remove duplicate decl.
14759 (x_own_selection): Remove needless cast to unsigned long.
14761 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14762 that always fit in int. Use a sentinel instead of a counter, to
14763 avoid a temp and to allay GCC's concerns about possible int overflow.
14764 * frame.h (struct frame): Use int for menu_bar_items_used
14765 instead of EMACS_INT, since it always fits in int.
14767 * menu.c (grow_menu_items): Check for int overflow.
14769 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14771 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14772 Before, the code was not consistent. These values cannot exceed
14773 2**31 - 1 so there's no need to make them unsigned.
14774 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14775 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14776 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14778 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14780 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14781 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14782 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14783 presumably because the widths might not match.
14785 * window.c (size_window): Avoid needless test at loop start.
14787 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14789 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14791 2011-05-12 Drew Adams <drew.adams@oracle.com>
14793 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14795 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14797 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14798 `width' to `bar_area_x' and `bar_area_width', respectively.
14799 (x_scroll_run): Take account of fringe background extension.
14801 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14802 Rename local vars `left' and `width' to `bar_area_x' and
14803 `bar_area_width', respectively.
14804 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14805 background extension.
14807 2011-05-10 Jim Meyering <meyering@redhat.com>
14809 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14811 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14813 * image.c (Finit_image_library): Return t for built-in image types,
14814 like pbm and xbm. (Bug#8640)
14816 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14818 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14820 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14822 * w32console.c (Fset_screen_color): Doc fix.
14823 (Fget_screen_color): New function.
14824 (syms_of_ntterm): Defsubr it.
14826 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14827 unlink the temporary file if Fcall_process didn't create it in the
14829 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14830 child process will be redirected to a file specified with `:file'.
14831 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14832 cue to call_process_cleanup not to close that handle.
14834 2011-05-07 Ben Key <bkey76@gmail.com>
14836 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14837 one of two shell specific rules, either bootstrap-temacs-CMD or
14838 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14839 to the previous implementation of the bootstrap-temacs rule.
14840 The bootstrap-temacs-CMD rule is similar to the previous
14841 implementation of the bootstrap-temacs rule except that it
14842 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14845 These changes, along with some changes to nt/configure.bat,
14846 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14847 earlier fix to add support for --cflags and --ldflags options
14848 that include quotes so that it works whether make uses cmd or
14851 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14853 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14854 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14856 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14857 a string. Handle both cases.
14858 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14859 (Fdbus_register_method): Use Qinvalid_function.
14861 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14863 * makefile.w32-in: Update dependencies.
14864 (LISP_H): Add inttypes.h and stdin.h.
14865 (PROCESS_H): Add unistd.h.
14867 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14869 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14870 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14872 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14874 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14876 * term.c (vfatal): Remove stray call to va_end.
14877 It's not needed and the C Standard doesn't allow it here anyway.
14879 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14880 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14882 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14885 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14887 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14889 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14891 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14893 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14895 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14896 * charset.c (Fdefine_charset_internal): Don't initialize
14897 charset.code_space[15]. The value was garbage, on hosts with
14898 32-bit int (Bug#8600).
14900 * lread.c (read_integer): Be more consistent with string-to-number.
14901 Use string_to_number to do the actual conversion; this avoids
14902 rounding errors and fixes some other screwups. Without this fix,
14903 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14904 (digit_to_number): Move earlier, for benefit of read_integer.
14905 Return -1 if the digit is out of range for the base, -2 if it is
14906 not a digit in any supported base. (Bug#8602)
14908 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14910 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14911 to match comment at start of function. This also removes a
14912 GCC warning about overflow in a 32+64-bit port.
14914 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14916 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14917 Reported by Stefan Monnier in
14918 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14919 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14920 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14922 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14923 (EMACS_UINTPTR): Likewise, with uintptr_t.
14925 * lisp.h: Prefer 64-bit EMACS_INT if available.
14926 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14927 on 32-bit hosts that have 64-bit int, so that they can access
14929 However, temporarily disable this change unless the temporary
14930 symbol WIDE_EMACS_INT is defined.
14932 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14934 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14935 This removes an assumption that EMACS_INT and long are the same
14936 width as pointers. The assumption is true for Emacs porting targets
14937 now, but we want to make other targets possible.
14938 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14939 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14940 In the rest of the code, change types of integers that hold casted
14941 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14942 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14943 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14944 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14945 No need to cast type when ORing.
14946 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14947 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14948 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14949 assume EMACS_INT is the same width as char *.
14950 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14951 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14952 Remove no-longer-needed casts.
14953 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14954 (xg_tool_bar_help_callback, xg_make_tool_item):
14955 Use EMACS_INTPTR to hold an integer
14956 that will be cast to void *; this can avoid a GCC warning
14957 if EMACS_INT is not the same width as void *.
14958 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14959 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14960 (current_message_1, set_message_1):
14961 Use a local to convert to proper width without a cast.
14962 * xmenu.c (dialog_selection_callback): Likewise.
14964 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14965 Also, don't assume VALBITS / RAND_BITS is less than 5,
14966 and don't rely on undefined behavior when shifting a 1 left into
14968 * lisp.h (get_random): Change signature to match.
14970 * lread.c (hash_string): Use size_t, not int, for hash computation.
14971 Normally we prefer signed values; but hashing is special, because
14972 it's better to use unsigned division on hash table sizes so that
14973 the remainder is nonnegative. Also, size_t is the natural width
14974 for hashing into memory. The previous code used 'int', which doesn't
14975 retain enough info to hash well into very large tables.
14976 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14978 * dbusbind.c: Don't possibly lose pointer info when converting.
14979 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14980 Use XPNTR rather than XHASH, so that the high-order bits of
14981 the pointer aren't lost when converting through void *.
14983 * eval.c (Fautoload): Don't double-shift a pointer.
14985 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14987 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14989 * gnutls.c (DEF_GNUTLS_FN):
14990 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14992 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14994 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14997 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14999 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
15000 New version that can reserve upto 2GB of heap space.
15002 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
15004 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
15006 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
15008 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
15009 `gnutls_certificate_set_x509_key_file'.
15011 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
15013 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
15014 Update dependencies.
15016 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15018 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
15019 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
15020 Remove unused parameter `fildes'.
15021 * process.c (read_process_output, send_process): Don't pass it.
15023 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15025 Fix previous change: the library cache is defined in w32.c.
15026 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
15027 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
15029 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15031 Implement dynamic loading of GnuTLS on Windows.
15033 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
15034 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
15035 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15038 * gnutls.c (Qgnutls_dll): Define.
15039 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
15040 (gnutls_*): Declare function pointers.
15041 (init_gnutls_functions): New function to initialize function pointers.
15042 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
15043 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
15044 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15045 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
15046 (emacs_gnutls_write, emacs_gnutls_read)
15047 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
15048 (Fgnutls_available_p): New function.
15049 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
15050 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
15051 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
15053 * image.c: Include w32.h.
15054 (Vimage_type_cache): Delete.
15055 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
15056 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
15057 (w32_delayed_load): Move to w32.c.
15059 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
15061 * w32.c (QCloaded_from, Vlibrary_cache): Define.
15062 (w32_delayed_load): Move from image.c. When loading a library, record
15063 its filename in the :loaded-from property of the library id.
15064 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
15065 Initialize and staticpro them.
15066 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
15068 * process.c: Include lisp.h before w32.h, not after.
15069 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
15070 instead of gnutls_record_check_pending.
15072 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
15074 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
15076 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
15077 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
15080 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
15082 * xterm.c (x_set_frame_alpha): Do not set property on anything
15083 else than FRAME_X_OUTER_WINDOW (Bug#8608).
15085 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
15087 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
15089 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
15091 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
15092 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

15098 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
15099 (Qgnutls_bootprop_callbacks_verify): Make static.
15101 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
15103 * callproc.c: Indentation fixup.
15105 * sysdep.c (wait_for_termination_1): Make static.
15106 (wait_for_termination, interruptible_wait_for_termination):
15107 Move after wait_for_termination_1.
15109 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
15111 * sysdep.c (interruptible_wait_for_termination): New function
15112 which is like wait_for_termination, but allows keyboard
15115 * callproc.c (Fcall_process): Add (:file "file") as an option for
15117 (Fcall_process_region): Ditto.
15119 2011-04-30 Eli Zaretskii <eliz@gnu.org>
15121 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
15122 rather than `XVECTOR (FOO)->size'.
15124 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
15125 inttypes.h, as a gnulib replacement is used if it not available in
15128 2011-04-21 Eli Zaretskii <eliz@gnu.org>
15130 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
15131 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
15132 of MOST_POSITIVE_FIXNUM. (Bug#8528)
15134 * coding.c (coding_alloc_by_realloc): Error out if destination
15135 will grow beyond MOST_POSITIVE_FIXNUM.
15136 (decode_coding_emacs_mule): Abort if there isn't enough place in
15137 charbuf for the composition carryover bytes. Reserve an extra
15138 space for up to 2 characters produced in a loop.
15139 (decode_coding_iso_2022): Abort if there isn't enough place in
15140 charbuf for the composition carryover bytes.
15142 2011-04-21 Eli Zaretskii <eliz@gnu.org>
15144 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
15145 aborting when %lld or %lll format is passed.
15146 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
15147 %llo or %llx format is passed. (Bug#8545)
15149 * window.c (window_scroll_line_based): Use a marker instead of
15150 simple variables to record original value of point. (Bug#7952)
15152 * doprnt.c (doprnt): Fix the case where a multibyte sequence
15153 produced by %s or %c overflows available buffer space. (Bug#8545)
15155 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
15157 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
15158 (SIZE_MAX): Move defn after all includes, as they might #define it.
15160 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15162 * w32.c (init_environment): Warn about defaulting HOME to C:\.

15166 * keyboard.c (Qdelayed_warnings_hook): Define.
15167 (command_loop_1): Run `delayed-warnings-hook'
15168 if Vdelayed_warnings_list is non-nil.
15169 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
15170 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
15172 2011-04-28 Eli Zaretskii <eliz@gnu.org>
15174 * doprnt.c (doprnt): Don't return value smaller than the buffer
15175 size if the message was truncated. (Bug#8545).
15177 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15179 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
15180 (Fx_window_property): #if-0 the whole functions, not just the bodies.
15182 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15184 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
15186 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
15188 * makefile.w32-in: Update dependencies.
15190 2011-04-27 Eli Zaretskii <eliz@gnu.org>
15192 Improve `doprnt' and its usage. (Bug#8545)
15193 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
15194 `format_end'. Remove support for %l as a conversion specifier.
15195 Don't use xrealloc. Improve diagnostics when the %l size modifier
15196 is used. Update the commentary.
15198 * eval.c (verror): Simplify calculation of size_t.
15200 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
15203 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
15205 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
15208 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15210 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
15211 This makes this file independent of the recent pseudovector change.
15213 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
15215 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
15217 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
15218 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
15219 Remove unused local.
15220 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
15222 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
15223 GCC 4.6.0 optimizes based on type-based alias analysis.
15224 For example, if b is of type struct buffer * and v of type struct
15225 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
15226 != &v->size, and therefore "v->size = 1; b->size = 2; return
15227 v->size;" must therefore return 1. This assumption is incorrect
15228 for Emacs, since it type-puns struct Lisp_Vector * with many other
15229 types. To fix this problem, this patch adds a new type struct
15230 vectorlike_header that documents the constraints on layout of vectors
15231 and pseudovectors, and helps optimizing compilers not get fooled
15232 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
15233 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
15234 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
15236 (XSETPVECTYPE): Rewrite in terms of new macro.
15237 (XSETPVECTYPESIZE): New macro, specifying both type and size.
15238 This is a bit clearer, and further avoids the possibility of
15239 undesirable aliasing.
15240 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
15241 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
15242 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
15243 since Lisp_Subr is a special case (no "next" field).
15244 (ASIZE): Now uses header.size rather than size.
15245 All previous uses of XVECTOR (foo)->size replaced to use this macro,
15246 to avoid the hassle of writing XVECTOR (foo)->header.size.
15247 (struct vectorlike_header): New type.
15248 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
15249 object, to help avoid aliasing.
15250 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
15251 (SUBRP): Likewise, since Lisp_Subr is a special case.
15252 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
15253 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
15254 (struct Lisp_Hash_Table): Combine first two members into a single
15255 struct vectorlike_header member. All uses of "size" and "next" members
15256 changed to be "header.size" and "header.next".
15257 * buffer.h (struct buffer): Likewise.
15258 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
15259 * frame.h (struct frame): Likewise.
15260 * process.h (struct Lisp_Process): Likewise.
15261 * termhooks.h (struct terminal): Likewise.
15262 * window.c (struct save_window_data, struct saved_window): Likewise.
15263 * window.h (struct window): Likewise.
15264 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
15265 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
15266 * buffer.c (init_buffer_once): Likewise.
15267 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
15269 * process.c (Fformat_network_address): Use local var for size,
15272 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
15274 Make the Lisp reader and string-to-float more consistent (Bug#8525)
15275 * data.c (atof): Remove decl; no longer used or needed.
15276 (digit_to_number): Move to lread.c.
15277 (Fstring_to_number): Use new string_to_number function, to be
15278 consistent with how the Lisp reader treats infinities and NaNs.
15279 Do not assume that floating-point numbers represent EMACS_INT
15280 without losing information; this is not true on most 64-bit hosts.
15281 Avoid double-rounding errors, by insisting on integers when
15282 parsing non-base-10 numbers, as the documentation specifies.
15283 * lisp.h (string_to_number): New decl, replacing ...
15284 (isfloat_string): Remove.
15285 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
15286 (read1): Do not accept +. and -. as integers; this
15287 appears to have been a coding error. Similarly, do not accept
15288 strings like +-1e0 as floating point numbers. Do not report
15289 overflow for integer overflows unless the base is not 10 which
15290 means we have no simple and reliable way to continue.
15291 Break out the floating-point parsing into a new
15292 function string_to_number, so that Fstring_to_number parses
15293 floating point numbers consistently with the Lisp reader.
15294 (digit_to_number): Move here from data.c. Make it static inline.
15295 (E_CHAR, EXP_INT): Remove, replacing with ...
15296 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
15297 (string_to_number): New function, replacing isfloat_string.
15298 This function checks for valid syntax and produces the resulting
15299 Lisp float number too. Rework it so that string-to-number
15300 no longer mishandles examples like "1.0e+". Use strtoumax,
15301 so that overflow for non-base-10 numbers is reported only when
15302 there's no portable and simple way to convert to floating point.
15304 * textprop.c (set_text_properties_1): Rewrite for clarity,
15305 and to avoid GCC warning about integer overflow.
15307 * intervals.h (struct interval): Use EMACS_INT for members
15308 where EMACS_UINT might cause problems. See
15309 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
15310 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
15311 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
15313 (offset_intervals): Tell GCC not to worry about length overflow
15314 when negating a negative length.
15316 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
15317 (overrun_check_free): Likewise.
15319 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
15320 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
15323 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15324 (gnutls_make_error): Rename local to avoid shadowing.
15325 (gnutls_emacs_global_deinit): ifdef out; not used.
15326 (Fgnutls_boot): Use const for pointer to readonly storage.
15327 Comment out unused local. Fix pointer signedness problems.
15329 * lread.c (openp): Don't stuff size_t into an 'int'.
15330 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
15331 about possible signed overflow.
15333 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15334 (GDK_KEY_g): Don't define if already defined.
15335 (xg_prepare_tooltip): Avoid pointer signedness problem.
15336 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
15338 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
15339 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
15341 * xfns.c (Fx_window_property): Simplify a bit,
15342 to make a bit faster and to avoid GCC 4.6.0 warning.
15343 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
15345 * fns.c (internal_equal): Don't assume size_t fits in int.
15347 * alloc.c (compact_small_strings): Tighten assertion a little.
15349 Replace pEd with more-general pI, and fix some printf arg casts.
15350 * lisp.h (pI): New macro, generalizing old pEd macro to other
15351 conversion specifiers. For example, use "...%"pI"d..." rather
15352 than "...%"pEd"...".
15353 (pEd): Remove. All uses replaced with similar uses of pI.
15354 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
15355 * alloc.c (check_pure_size): Don't overflow by converting size to int.
15356 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
15357 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
15358 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
15359 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
15360 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
15362 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
15363 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
15364 * print.c (safe_debug_print, print_object): Likewise.
15365 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
15367 Use pI instead of if-then-else-abort. Use %p to avoid casts,
15368 avoiding the 0 flag, which is not portable.
15369 * process.c (Fmake_network_process): Use pI to avoid cast.
15370 * region-cache.c (pp_cache): Likewise.
15371 * xdisp.c (decode_mode_spec): Likewise.
15372 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
15373 behavior on 64-bit hosts with printf arg.
15374 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
15375 (x_stop_queuing_selection_requests): Likewise.
15376 (x_get_window_property): Don't truncate byte count to an 'int'
15379 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
15380 here, since it parses constructs like leading '-' and spaces,
15381 which are not wanted; and it overflows with large numbers.
15382 Instead, simply match F[0-9]+, which is what is wanted anyway.
15384 * alloc.c: Remove unportable assumptions about struct layout.
15385 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
15386 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
15387 (allocate_vectorlike, make_pure_vector): Use the new macros,
15388 plus offsetof, to remove unportable assumptions about struct layout.
15389 These assumptions hold on all porting targets that I know of, but
15390 they are not guaranteed, they're easy to remove, and removing them
15391 makes further changes easier.
15393 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
15394 This doesn't fix a bug but makes the code clearer.
15395 (string_overrun_cookie): Now const. Use initializers that
15396 don't formally overflow signed char, to avoid warnings.
15397 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
15398 can cause Emacs to crash when string overrun checking is enabled.
15399 (allocate_buffer): Don't assume sizeof (struct buffer) is a
15400 multiple of sizeof (EMACS_INT); it need not be, if
15401 alignof(EMACS_INT) < sizeof (EMACS_INT).
15402 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
15404 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

15408 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
15410 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
15411 supposed to be handshaking. (Bug#8556)
15412 Reported by Paul Eggert <eggert@cs.ucla.edu>.
15414 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

15419 (handle_user_signal): Break into debugger when debug-on-event
15420 matches the current signal symbol.
15422 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
15424 * alloc.c (check_sblock, check_string_bytes)
15425 (check_string_free_list): Convert to standard C.
15427 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
15429 * w32.c (emacs_gnutls_push): Fix typo.
15431 2011-04-25 Eli Zaretskii <eliz@gnu.org>
15433 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
15434 "cast to pointer from integer of different size".
15436 Improve doprnt and its use in verror. (Bug#8545)
15437 * doprnt.c (doprnt): Document the set of format control sequences
15438 supported by the function. Use SAFE_ALLOCA instead of always
15441 * eval.c (verror): Don't limit the buffer size at size_max-1, that
15442 is one byte too soon. Don't use xrealloc; instead xfree and
15445 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
15447 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
15450 * gnutls.c: Renamed global_initialized to
15451 gnutls_global_initialized. Added internals for the
15452 :verify-hostname-error, :verify-error, and :verify-flags
15453 parameters of `gnutls-boot' and documented those parameters in the
15454 docstring. Start callback support.
15455 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
15456 unless a fatal error occurred. Call gnutls_alert_send_appropriate
15457 on error. Return error code.
15458 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
15459 (emacs_gnutls_read): Likewise.
15460 (Fgnutls_boot): Return handshake error code.
15461 (emacs_gnutls_handle_error): New function.
15462 (wsaerror_to_errno): Likewise.

15524 <char-direction-table>: Deleted.
15526 2011-04-23 Eli Zaretskii <eliz@gnu.org>
15528 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
15529 * doprnt.c: Include limits.h.
15530 (SIZE_MAX): New macro.
15531 (doprnt): Return a size_t value. 2nd arg is now size_t.
15532 Many local variables are now size_t instead of int or unsigned.
15533 Improve overflow protection. Support `l' modifier for integer
15534 conversions. Support %l conversion. Don't assume an EMACS_INT
15535 argument for integer conversions and for %c.
15537 * lisp.h (doprnt): Restore prototype.
15539 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
15540 $(SRC)/character.h.
15542 * Makefile.in (base_obj): Add back doprnt.o.
15544 * deps.mk (doprnt.o): Add back prerequisites.
15545 (callint.o): Depend on character.h.
15547 * eval.c (internal_lisp_condition_case): Include the handler
15548 representation in the error message.
15549 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
15550 when breaking from the loop.
15552 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
15554 * callint.c (Fcall_interactively): When displaying error message
15555 about invalid control letter, pass the character's codepoint, not
15556 a pointer to its multibyte form. Improve display of the character
15557 in octal and display also its hex code.
15559 * character.c (char_string): Use %x to display the (unsigned)
15560 codepoint of an invalid character, to avoid displaying a bogus
15563 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15564 `error', not SYMBOL_NAME itself.
15566 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
15567 character arguments to `error'.
15569 * charset.c (check_iso_charset_parameter): Fix incorrect argument
15570 to `error' in error message about FINAL_CHAR argument. Make sure
15571 FINAL_CHAR is a character, and use %c when it is passed as
15572 argument to `error'.
15574 2011-04-23 Eli Zaretskii <eliz@gnu.org>

15642 * dispextern.h (struct redisplay_interface): Rename param

15761 * nsfont.m: Fixed bugs in ns_get_family and
15762 ns_descriptor_to_entity that were caused by using free to
15763 deallocate memory blocks that were allocated by xmalloc (via
15764 xstrdup). This caused Emacs to crash when compiled with
15765 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
15766 --enable-checking=xmallocoverrun). xfree is now used to
15767 deallocate these memory blocks.

15783 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
15784 (emacs_read, emacs_write): Use it.
15785 * process.c (send_process): Adjust to the new signatures of
15786 emacs_write and emacs_gnutls_write. Do not attempt to store

16116 * lisp.h: Remove these decls.
16118 * buffer.c (buffer_count): Remove unused var.
16120 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
16121 so that it's not optimized away.
16122 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
16123 * dispextern.h (bidi_dump_cached_states): Remove, since it's
16124 exported only to the debugger.
16126 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
16127 * atimer.h (run_all_atimers): Remove; not exported.
16129 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
16130 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
16131 was inaccessible from Lisp.
16132 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
16133 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
16135 alloc.c: Import and export fewer symbols, and remove unused items.
16136 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
16138 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
16139 it's not optimized away by whole-program optimization.
16140 (message_enable_multibyte, free_misc): Remove.
16141 (catchlist, handlerlist, mark_backtrace):
16142 Declare only if BYTE_MARK_STACK.

16151 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
16152 (mark_backtrace): Define only if BYTE_MARK_STACK.
16153 * xdisp.c (message_enable_multibyte): Now static.
16155 Declare Lisp_Object Q* variables to be 'static' if not exported.
16156 This makes it easier for human readers (and static analyzers)
16157 to see whether these variables are used from other modules.
16158 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
16159 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
16160 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

16167 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
16168 Remove decls of unexported vars.
16169 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
16171 * lisp.h (DEFINE_FUNC): Make sname 'static'.
16173 Make Emacs functions such as Fatom 'static' by default.
16174 This makes it easier for human readers (and static analyzers)
16175 to see whether these functions can be called from other modules.
16176 DEFUN now defines a static function. To make the function external
16177 so that it can be used in other C modules, use the new macro DEFUE.
16178 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
16179 (Finit_image_library):
16180 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
16181 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
16182 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
16183 Remove decls, since these functions are now static.
16184 (Funintern, Fget_internal_run_time): New decls, since these functions
16185 were already external.
16187 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
16188 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

16194 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
16195 Mark functions with DEFUE instead of DEFUN,
16196 if they are used in other modules.
16197 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
16198 decls for now-static functions.
16199 * buffer.h (Fdelete_overlay): Remove decl.
16200 * callproc.c (Fgetenv_internal): Mark as internal.

16209 * image.c (Finit_image_library): New forward static decl.
16210 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
16211 * intervals.h (Fprevious_property_change):
16212 (Fremove_list_of_text_properties): Remove decls.
16213 * keyboard.c (Fthis_command_keys): Remove decl.
16214 (Fcommand_execute): New forward static decl.

16230 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
16232 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
16235 2011-04-13 Eli Zaretskii <eliz@gnu.org>
16237 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
16238 when at ZV. (Bug#8487)
16240 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
16242 * charset.c (Fclear_charset_maps): Use xfree instead of free.

16245 * sound.c (sound_cleanup, alsa_close): Likewise.
16246 * termcap.c (tgetent): Likewise.
16247 * xfns.c (x_default_font_parameter): Likewise.
16248 * xsettings.c (read_and_apply_settings): Likewise.
16250 * alloc.c (overrun_check_malloc, overrun_check_realloc)
16251 (overrun_check_free): Protoize.
16253 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
16255 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
16256 since callers should never pass a negative size.
16257 Change the signature to match that of plain 'read' and 'write'; see
16258 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
16259 * lisp.h: Update prototypes of emacs_write and emacs_read.
16261 2011-04-11 Eli Zaretskii <eliz@gnu.org>
16263 * xdisp.c (redisplay_window): Don't try to determine the character
16264 position of the scroll margin if the window start point w->startp
16265 is outside the buffer's accessible region. (Bug#8468)
16267 2011-04-10 Eli Zaretskii <eliz@gnu.org>
16269 Fix write-region and its subroutines for buffers > 2GB.
16270 * fileio.c (a_write, e_write): Modify declaration of arguments and
16271 local variables to support buffers larger than 2GB.
16272 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
16274 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
16275 argument, local variables, and return value.
16277 * lisp.h: Update prototypes of emacs_write and emacs_read.
16279 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
16281 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
16283 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
16285 Fix more problems found by GCC 4.6.0's static checks.
16287 * xdisp.c (vmessage): Use a better test for character truncation.
16289 * charset.c (load_charset_map): <, not <=, for optimization,
16290 and to avoid potential problems with integer overflow.
16291 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
16292 * casetab.c (set_identity, shuffle): Likewise.
16293 * editfns.c (Fformat): Likewise.
16294 * syntax.c (skip_chars): Likewise.
16296 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
16297 This also lets GCC 4.6.0 generate slightly better loop code.
16299 * callint.c (Fcall_interactively): <, not <=, for optimization.
16300 (Fcall_interactively): Count the number of arguments produced,
16301 not the number of arguments given. This is simpler and lets GCC
16302 4.6.0 generate slightly better code.
16304 * ftfont.c: Distingish more carefully between FcChar8 and char.
16305 The previous code passed unsigned char * to a functions like
16306 strlen and xstrcasecmp that expect char *, which does not
16307 conform to the C standard.
16308 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
16309 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
16310 char * when the C standard requires it.
16312 * keyboard.c (read_char): Remove unused var.
16314 * eval.c: Port to Windows vsnprintf (Bug#8435).
16315 Include <limits.h>.
16316 (SIZE_MAX): Define if the headers do not.
16317 (verror): Do not give up if vsnprintf returns a negative count.
16318 Instead, grow the buffer. This ports to Windows vsnprintf, which
16319 does not conform to C99. Problem reported by Eli Zaretskii.
16320 Also, simplify the allocation scheme, by avoiding the need for
16321 calling realloc, and removing the ALLOCATED variable.
16323 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
16325 Remove invocations of doprnt, as Emacs now uses vsnprintf.
16326 But keep the doprint source code for now, as we might revamp it
16327 and use it again (Bug#8435).
16328 * lisp.h (doprnt): Remove.
16329 * Makefile.in (base_obj): Remove doprnt.o.
16330 * deps.mk (doprnt.o): Remove.
16332 error: Print 32- and 64-bit integers portably (Bug#8435).
16333 Without this change, on typical 64-bit hosts error ("...%d...", N)
16334 was used to print both 32- and 64-bit integers N, which relied on
16335 undefined behavior.
16336 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
16337 * lisp.h (error, verror): Mark as printf-like functions.
16338 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
16339 Report overflow in size calculations when allocating printf buffer.
16340 Do not truncate output string at its first null byte.
16341 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
16342 Truncate the output at a character boundary, since vsnprintf does not
16344 * charset.c (check_iso_charset_parameter): Convert internal
16345 character to string before calling 'error', since %c now has the
16347 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
16348 overflow when computing char to be passed to 'error'. Do not
16349 pass Lisp_Object to 'error'; pass the integer instead.
16350 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
16351 formatted with plain %d.
16353 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
16355 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
16357 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
16359 * xterm.c (x_catch_errors): Remove duplicate declaration.
16361 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
16363 * xdisp.c, lisp.h (message_nolog): Remove; unused.
16365 2011-04-10 Jim Meyering <meyering@redhat.com>
16367 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
16368 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
16369 return ssize_t not "int", and use size_t as the buffer length.
16370 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
16371 * gnutls.h: Update declarations.
16372 * process.c (read_process_output): Use ssize_t, to match.
16373 (send_process): Likewise.
16375 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16377 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
16379 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16381 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
16382 Use unsigned char, to match FcChar8 type definition.
16384 * xterm.c (handle_one_xevent):
16385 * xmenu.c (create_and_show_popup_menu):
16386 * xselect.c (x_decline_selection_request)
16387 (x_reply_selection_request): Avoid type-punned deref of X events.
16389 2011-04-09 Eli Zaretskii <eliz@gnu.org>
16391 Fix some uses of `int' instead of EMACS_INT.
16392 * search.c (string_match_1, fast_string_match)
16393 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
16394 (scan_buffer, find_next_newline_no_quit)
16395 (find_before_next_newline, search_command, Freplace_match)
16396 (Fmatch_data): Make some `int' variables be EMACS_INT.
16398 * xdisp.c (display_count_lines): 3rd argument and return value now
16399 EMACS_INT. All callers changed.
16400 (pint2hrstr): Last argument is now EMACS_INT.
16402 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
16403 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
16404 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

16415 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
16416 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
16418 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
16419 (encode_invocation_designation): Last argument P_NCHARS is now
16421 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
16422 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
16424 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
16427 * ccl.c (Fccl_execute_on_string): Declare some variables
16430 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
16432 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
16434 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
16436 * process.c (Fformat_network_address): Doc fix.
16438 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
16440 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
16442 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
16444 * keyboard.c (read_char): Call Lisp function help-form-show,
16445 instead of using internal_with_output_to_temp_buffer.
16446 (Qhelp_form_show): New var.
16447 (syms_of_keyboard): Use DEFSYM macro.
16449 * print.c (internal_with_output_to_temp_buffer): Function deleted.

16453 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
16455 * process.c (Flist_processes): Remove to Lisp.
16456 (list_processes_1): Delete.
16458 2011-04-06 Eli Zaretskii <eliz@gnu.org>
16460 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
16462 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
16464 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
16466 Fix more problems found by GCC 4.6.0's static checks.

16472 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
16474 * xdisp.c (vmessage): Mark as a printf-like function.
16476 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
16478 * sound.c (sound_warning): Don't crash if arg contains a printf format.

16483 to system-supplied API.
16485 * eval.c (Fsignal): Remove excess argument to 'fatal'.
16487 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
16488 This avoids several warnings with gcc -Wstrict-overflow.
16489 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
16490 directly, rather than having caller test rule sign. This avoids
16491 some unnecessary tests.
16492 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
16493 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
16494 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
16496 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16497 (xfont_open): Avoid unnecessary tests.
16499 * composite.c (composition_gstring_put_cache): Use unsigned integer.
16501 * composite.h, composite.c (composition_gstring_put_cache):
16502 Use EMACS_INT, not int, for length.
16504 * composite.h (COMPOSITION_DECODE_REFS): New macro,
16505 breaking out part of COMPOSITION_DECODE_RULE.
16506 (COMPOSITION_DECODE_RULE): Use it.
16507 * composite.c (get_composition_id): Remove unused local vars,
16508 by using the new macro.
16510 * textprop.c (set_text_properties_1): Change while to do-while,
16511 since the condition is always true at first.
16513 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16514 (interval_deletion_adjustment): Return unsigned value.
16517 * process.c (list_processes_1, create_pty, read_process_output):
16518 (exec_sentinel): Remove vars that were set but not used.
16519 (create_pty): Remove unnecessary "volatile"s.
16520 (Fnetwork_interface_info): Avoid possibility of int overflow.

16533 * print.c (print_error_message): Avoid int overflow.
16535 * font.c (font_list_entities): Redo for clarity,
16536 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
16538 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
16539 (font_score): Avoid potential overflow in diff calculation.
16541 * fns.c (substring_both): Remove var that is set but not used.
16542 (sxhash): Redo loop for clarity and to avoid wraparound warning.
16544 * eval.c (funcall_lambda): Rename local to avoid shadowing.
16546 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
16547 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
16548 can always succeed if overflow has undefined behavior.
16550 * search.c (boyer_moore, wordify): Remove vars set but not used.
16551 (wordify): Omit three unnecessary tests.
16553 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
16554 All callers changed. This avoids the need for an unused var.
16556 * casefiddle.c (casify_region): Remove var that is set but not used.
16558 * dired.c (file_name_completion): Remove var that is set but not used.
16560 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
16562 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16563 (Finsert_file_contents): Remove unnecessary code checking fd.
16565 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
16566 Check for integer overflow on size calculations.
16568 * buffer.c (Fprevious_overlay_change): Remove var that is set
16571 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16572 Remove vars that are set but not used.
16573 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16574 (timer_check_2): Mark vars as initialized.
16576 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16578 * image.c (lookup_image): Remove var that is set but not used.
16579 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16581 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16582 that are set but not used.
16584 * xfns.c (make_invisible_cursor): Don't return garbage
16585 if XCreateBitmapFromData fails (Bug#8410).
16587 * xselect.c (x_get_local_selection, x_handle_property_notify):
16588 Remove vars that are set but not used.
16590 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
16591 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
16593 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
16594 Remove var that is set but not used.
16595 (scroll_bar_windows_size): Now size_t, not int.
16596 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16597 Check for overflow.
16599 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16600 (map_tty_color) [!defined MSDOS]: Likewise.
16602 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16604 * coding.c: Remove vars that are set but not used.
16605 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
16606 All callers changed.
16607 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
16608 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
16609 (decode_coding_charset): Remove vars that are set but not used.
16611 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
16612 that is set but not used.
16614 * print.c (print_object): Remove var that is set but not used.
16616 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16617 The gnulib version avoids calling malloc in the usual case,
16618 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16619 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16620 * filelock.c (current_lock_owner): Likewise.
16621 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16622 * sysdep.c: Include allocator.h, careadlinkat.h.
16623 (emacs_no_realloc_allocator): New static constant.
16624 (emacs_readlink): New function.
16625 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16626 ../lib/careadlinkat.h.
16628 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
16630 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
16631 first non-nil return value).
16633 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
16635 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
16636 if not defined (Bug#8403).
16638 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16640 * xdisp.c (display_count_lines): Remove parameter `start',
16641 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16642 (get_char_face_and_encoding): Remove parameter `multibyte_p',
16643 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

16645 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
16646 and thereabouts. All callers changed.
16647 (get_per_char_metric): Remove parameter `f', unused since
16648 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
16650 2011-04-02 Jim Meyering <meyering@redhat.com>
16652 do not dereference NULL upon failed strdup
16653 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16654 (ns_get_family): Likewise.
16656 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16658 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16660 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16662 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16665 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16667 Add lexical binding.
16669 * window.c (Ftemp_output_buffer_show): New fun.
16670 (Fsave_window_excursion):
16671 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
16673 * lread.c (lisp_file_lexically_bound_p): New function.
16674 (Fload): Bind Qlexical_binding.
16675 (readevalloop): Remove `evalfun' arg.
16676 Bind Qinternal_interpreter_environment.
16677 (Feval_buffer): Bind Qlexical_binding.
16678 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16680 (syms_of_lread): Declare `lexical-binding'.
16682 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16684 * keyboard.c (eval_dyn): New fun.
16685 (menu_item_eval_property): Use it.
16687 * image.c (parse_image_spec): Use Ffunctionp.
16689 * fns.c (concat, mapcar1): Accept byte-code-functions.
16691 * eval.c (Fsetq): Handle lexical vars.
16692 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16693 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16694 (FletX, Flet): Obey lexical binding.
16695 (Fcommandp): Handle closures.
16696 (Feval): New `lexical' arg.
16697 (eval_sub): New function extracted from Feval. Use it almost
16698 everywhere where Feval was used. Look up vars in lexical env.
16700 (Ffunctionp): Move from subr.el.
16701 (Ffuncall): Handle closures.
16702 (apply_lambda): Remove `eval_flags'.
16703 (funcall_lambda): Handle closures and new byte-code-functions.
16704 (Fspecial_variable_p): New function.
16705 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16706 but without exporting it to Lisp.
16708 * doc.c (Fdocumentation, store_function_docstring):
16709 * data.c (Finteractive_form): Handle closures.
16711 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16714 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16716 (exec_byte_code): New function extracted from Fbyte_code to handle new
16717 calling convention for byte-code-functions. Add new byte-codes.
16719 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
16721 * alloc.c (Fmake_symbol): Init new `declared_special' field.
16723 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16725 * xdisp.c (redisplay_internal): Fix prototype.
16727 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16729 * xdisp.c (SCROLL_LIMIT): New macro.
16730 (try_scrolling): Use it when setting scroll_limit.
16731 Limit scrolling to 100 screen lines.
16732 (redisplay_window): Even when falling back on "recentering",
16733 position point in the window according to scroll-conservatively,
16734 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16736 (try_scrolling): When point is above the window, allow searching
16737 as far as scroll_max, or one screenful, to compute vertical
16738 distance from PT to the scroll margin position. This prevents
16739 try_scrolling from unnecessarily failing when
16740 scroll-conservatively is set to a value slightly larger than the
16741 window height. Clean up the case of PT below the margin at bottom
16742 of window: scroll_max can no longer be INT_MAX. When aggressive
16743 scrolling is in use, don't let point enter the opposite scroll
16744 margin as result of the scroll.
16745 (syms_of_xdisp) <scroll-conservatively>: Document the
16746 threshold of 100 lines for never-recentering scrolling.
16748 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16750 * dispextern.h (move_it_by_lines):
16751 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

16753 (message_log_check_duplicate): Remove parameters `prev_bol' and
16754 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16755 (redisplay_internal): Remove parameter `preserve_echo_area',
16756 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16758 * indent.c (Fvertical_motion):
16759 * window.c (window_scroll_pixel_based, Frecenter):
16760 Don't pass `need_y_p' to `move_it_by_lines'.
16762 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16764 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16765 steal a few bits to be more compact.
16766 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16767 Remove unneeded casts.
16769 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16771 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16773 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16774 binding" message (bug#7967).
16776 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16778 Fix more problems found by GCC 4.6.0's static checks.
16780 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16781 Remove unused local var.
16783 * editfns.c (Fmessage_box): Remove unused local var.
16785 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16786 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16787 Omit unused local vars.
16788 * window.c (shrink_windows): Omit unused local var.
16789 * menu.c (digest_single_submenu): Omit unused local var.
16790 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16791 Omit unused local var.
16793 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16794 Don't assume string length fits in int.
16795 (keyremap_step, read_key_sequence): Use size_t for sizes.
16796 (read_key_sequence): Don't check last_real_key_start redundantly.
16798 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
16799 instead of alloca (Bug#8344).
16801 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16802 (Fbacktrace_frame): Don't assume nframes fits in int.
16804 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

16809 * term.c (produce_glyphless_glyph): Remove unnecessary test.
16811 * cm.c (calccost): Turn while-do into do-while, for clarity.
16813 * keyboard.c (syms_of_keyboard): Use the same style as later
16814 in this function when indexing through an array. This also
16815 works around GCC bug 48267.
16817 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16819 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16821 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16822 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16824 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16825 This avoids undefined behavior on integer overflow, and is a bit
16826 more convenient anyway since it is compared to a size_t variable.
16828 Variadic C functions now count arguments with size_t, not int.
16829 This avoids an unnecessary limitation on 64-bit machines, which
16830 caused (substring ...) to crash on large vectors (Bug#8344).
16831 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
16832 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

16840 * fns.c (concat): Likewise.
16841 * frame.c (x_set_frame_parameters): Likewise.
16842 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16843 0 if not found, not -1. All callers changed.
16845 * alloc.c (garbage_collect): Don't assume stack size fits in int.
16846 (stack_copy_size): Now size_t, not int.
16847 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
16849 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
16851 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
16852 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
16853 All callers changed.
16855 * lisp.h (multibyte_char_to_unibyte):
16856 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
16857 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

16868 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
16869 don't set the hook to nil, but remove the offending function instead.
16870 (Qcommand_hook_internal): Remove, unused.
16871 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
16872 Vcommand_hook_internal.
16874 * eval.c (enum run_hooks_condition): Remove.
16875 (funcall_nil, funcall_not): New functions.
16876 (run_hook_with_args): Call each function through a `funcall' argument.
16877 Remove `cond' argument, now redundant.

16890 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
16891 All callers changed.
16893 * w32.c (_wsa_errlist): Use braces for struct initializers.
16895 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
16896 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
16897 All callers changed.

17042 * term.c (Fsuspend_tty, Fresume_tty):
17043 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
17044 * window.c (temp_output_buffer_show):

17053 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
17055 (command_loop_1): Use Frun_hooks. Call safe_run_hooks

17058 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
17060 Fix more problems found by GCC 4.5.2's static checks.
17062 * coding.c (encode_coding_raw_text): Avoid unnecessary test
17063 the first time through the loop, since we know p0 < p1 then.
17064 This also avoids a gcc -Wstrict-overflow warning.
17066 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
17067 leading to a memory leak, possible in functions like
17068 load_charset_map_from_file that can allocate an unbounded number
17069 of objects (Bug#8318).
17071 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
17072 that could (at least in theory) be that large.
17074 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
17075 This is less likely to overflow, and avoids undefined behavior if
17076 overflow does occur. All callers changed. Use strtoul to scan
17077 for the unsigned long integer.
17078 (pint2hrstr): Simplify and tune code slightly.
17079 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

17089 * fileio.c (Fcopy_file): Report error if fchown or fchmod
17092 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
17094 * process.c (Fmake_network_process): Use socklen_t, not int,
17095 where POSIX says socklen_t is required in portable programs.
17096 This fixes a porting bug on hosts like 64-bit HP-UX, where
17097 socklen_t is wider than int (Bug#8277).
17098 (Fmake_network_process, server_accept_connection):
17099 (wait_reading_process_output, read_process_output):
17102 * process.c: Rename or move locals to avoid shadowing.

17112 Make tparam.h and terminfo.c consistent.
17113 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
17114 Include tparam.h instead, since it declares them.
17115 * cm.h (PC): Remove extern decl; tparam.h now does this.
17116 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
17117 * terminfo.c: Include tparam.h, to check interfaces.
17118 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
17119 (tparam): Adjust signature to match interface in tparam.h;
17120 this removes some undefined behavior. Check that outstring and len
17121 are zero, which they always are with Emacs.
17122 * tparam.h (PC, BC, UP): New extern decls.
17124 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
17125 (xftfont_open): Rename locals to avoid shadowing.
17127 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

17139 * composite.c (composition_compute_stop_pos): Rename local to
17141 (composition_reseat_it): Remove unused locals.
17142 (find_automatic_composition, composition_adjust_point): Likewise.
17143 (composition_update_it): Mark var as initialized.
17144 (find_automatic_composition): Mark vars as initialized,
17145 with a FIXME (Bug#8290).

17148 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
17149 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
17150 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
17151 (BUF_DEC_POS): Be more systematic about renaming local temporaries
17152 to avoid shadowing.
17154 * textprop.c (property_change_between_p): Remove; unused.
17156 * intervals.c (interval_start_pos): Now static.
17158 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

17164 Fix pointer signedness.
17165 (alsa_choose_format): Remove unused local var.
17166 (wav_play): Initialize a variable to 0, to prevent undefined
17167 behavior (Bug#8278).
17169 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
17171 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
17173 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
17174 clobbering (Bug#8298).
17175 * sysdep.c (sys_subshell): Likewise.
17176 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
17178 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
17179 This should get cleaned up, so that child_setup has the
17180 same signature on all platforms.
17182 * callproc.c (call_process_cleanup): Now static.
17183 (relocate_fd): Rename locals to avoid shadowing.
17185 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
17187 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
17188 not to be necessary, and produces flickering.
17190 2011-03-20 Glenn Morris <rgm@gnu.org>
17192 * config.in: Remove file.
17194 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
17196 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
17197 are now in src/globals.h.
17198 (syms_of_minibuf): Remove spurious & from previous change.

17208 * xfaces.c (Fx_load_color_file):
17209 Read color file from absolute filename (bug#8250).

17224 (sigchld_handler): Now static.
17226 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
17227 That way, the code declares only the vars that it needs.

17237 (CONSTANTLIM): Remove; unused.
17238 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
17239 Define only if needed.
17241 * unexelf.c (unexec): Name an expression,
17242 to avoid gcc -Wbad-function-cast warning.
17243 Use a different way to cause a compilation error if anyone uses
17244 n rather than nn, a way that does not involve shadowing.
17245 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
17247 * deps.mk (unexalpha.o): Remove; unused.
17249 New file unexec.h, the (simple) interface for unexec (Bug#8267).

17316 (Ftranslate_region_internal, Fformat):
17317 Rename or remove local vars to avoid shadowing.

17320 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
17323 * lisp.h (eassert): Check that the argument compiles, even if
17324 ENABLE_CHECKING is not defined.
17326 * data.c (Findirect_variable): Name an expression, to avoid
17327 gcc -Wbad-function-cast warning.

17344 (Fmemory_limit): Cast sbrk's returned value to char *.

17370 (RETALLOC_IF): Define only if needed.
17371 (WORDCHAR_P): Likewise. This one is never needed, but is used
17372 only in a comment talking about a compiler bug, so put inside
17373 the #if 0 of that comment.

17403 gcpro1, gcpro2, etc.
17404 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
17406 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second

17411 Rename locals to avoid shadowing.
17413 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).

17422 (downcase, upcase1): New static inline functions.
17423 (DOWNCASE, UPCASE1): Reimplement using these functions.
17424 This avoids undefined behavior in expressions like

17458 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

17465 * buffer.c (fix_overlays_before): Mark locals as initialized.
17466 (fix_start_end_in_overlays): Likewise. This function should be
17467 simplified by using pointers-to-pointers, but that's a different

17476 to suppress a gcc -Wclobbered warning that does not seem to be right.
17477 (MAXPATHLEN): Define only if needed.
17479 * process.c (serial_open, serial_configure): Move decls from here ...
17480 * systty.h: ... to here, so that they can be checked.

17826 a block, when the outer 'i' will do.

17839 -Wuninitialized does not deduce are never used uninitialized.
17840 (detect_coding_iso_2022): Initialize a local variable that might
17841 be used uninitialized. Leave a FIXME because it's not clear that
