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

28 (syms_of_alloc): Define Qautomatic_gc.
29 * eval.c (eval_sub, Ffuncall): Reorder assignments to avoid
31 (struct backtrace): Move definition...
32 * lisp.h (struct backtrace): ..here.

39 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
41 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
43 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
45 Prefer POSIX timers if available.
46 They avoid a race if the timer is too close to the current time.
47 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
48 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

76 2012-09-25 Eli Zaretskii <eliz@gnu.org>
78 * w32proc.c (sys_signal): Handle all signals defined by the
79 MS-Windows runtime, not just SIGCHLD. Actually install the signal
80 handlers for signals supported by Windows. Don't override
81 term_ntproc as the handler for SIGABRT.
82 (sigaction): Rewrite to call sys_signal instead of duplicating its
84 (sys_kill): Improve commentary.
86 * w32.c (term_ntproc): Accept (and ignore) one argument, for
87 consistency with a signature of a signal handler. All callers
89 (init_ntproc): Accept an argument DUMPING. If dumping, don't
90 install term_ntproc as a signal handler for SIGABRT, as that
91 should be done by the dumped Emacs.
93 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
95 * w32select.c (term_w32select): Protect against repeated
96 invocation by setting clipboard_owner to NULL after calling
99 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
100 and term_ntproc to their modified signatures.
102 * character.c (char_string, string_char): Remove calls to
103 MAYBE_UNIFY_CHAR. See the discussion starting at
104 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html

114 when encountering an unknown bytecode.
116 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
118 image.c, indent.c: Use bool for booleans.
119 * dispextern.h (struct image_type): Members valid_p, load, init
120 now return bool, not int. All uses changed.
121 * image.c: Omit unnecessary static decls.
122 (x_create_bitmap_mask, x_build_heuristic_mask):
123 Return void, not int, since callers don't care about the return value.
124 (x_create_bitmap_mask, define_image_type, valid_image_p)

158 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
160 Move pid_t related decls out of lisp.h.
161 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
162 (interruptible_wait_for_termination):
163 Move these decls from lisp.h to syswait.h, since they use pid_t.
164 Needed on FreeBSD; see Herbert J. Skuhra in
165 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
166 * callproc.c: Include syswait.h.

186 Use bool for boolean.
187 * gtkutil.c (xg_update_frame_menubar):
188 * xmenu.c (update_frame_menubar):
189 Return void, not int, since caller ignores return value.

193 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
195 * makefile.w32-in (BLOCKINPUT_H): Remove.

212 2012-09-23 Eli Zaretskii <eliz@gnu.org>
214 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
215 fatal_error_backtrace.
217 * w32proc.c (sys_kill): Undo last change: don't do anything when
218 invoked to deliver SIGABRT to our own process. This is now
219 handled by emacs_raise.
221 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
223 * w32term.c (w32_read_socket): Remove leftover reference to
224 interrupt_input_pending.
226 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
228 Do not use SA_NODEFER.
229 Problem reported by Dani Moncayo in
230 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
232 * sysdep.c (emacs_abort): Do not reset signal handler.
233 * emacs.c (terminate_due_to_signal): Reset signal handler here.
234 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
235 wanted even on POSIXish hosts, and it doesn't work on Windows.
237 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
239 * xterm.c (x_term_init): Call fixup_locale before and after calling
240 gtk_init (Bug#12392).
242 2012-09-23 Chong Yidong <cyd@gnu.org>
244 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
245 Vdynamic_library_alist.
247 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
248 (Fgnutls_available_p): Caller changed.
250 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
251 (Flibxml_parse_xml_region): Likewise.
253 * dispextern.h (struct image_type): Remove arg from init function.
255 * image.c (Finit_image_library, lookup_image_type)
256 (define_image_type): Remove now-unneeded second arg.
257 (init_xpm_functions, init_png_functions, init_jpeg_functions)
258 (init_tiff_functions, init_gif_functions, init_svg_functions):
259 Arglist and w32_delayed_load calling convention changed.
260 (gs_type): Remove init_gs_functions; there is no such function.
261 (valid_image_p, make_image): Fix caller to lookup_image_type.
263 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
265 Simplify and avoid signal-handling races (Bug#12471).
267 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
268 Avoid recursive loop if there's a fatal error in the function itself.
269 * atimer.c (pending_atimers):
270 * blockinput.h: Don't include "atimer.h"; no longer needed.
271 (interrupt_input_pending): Remove. All uses removed.
272 pending_signals now counts both atimers and ordinary interrupts.
273 This is less racy than having three separate pending-signal flags.
274 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
276 Rename from their upper-case counterparts BLOCK_INPUT,
277 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
278 INPUT_BLOCKED_P, and turn into functions. All uses changed.
279 This makes it easier to access volatile variables more accurately.
280 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
281 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
282 that's more reliable if the code is buggy and sets
283 interrupt_input_blocked to a negative value. All uses changed.
284 * atimer.c (deliver_alarm_signal):
285 Remove. No need to deliver this to the parent; any thread can
286 handle this signal now. All uses replaced by underlying handler.
287 * atimer.c (turn_on_atimers):
288 * dispnew.c (handle_window_change_signal):
289 * emacs.c (handle_danger_signal):
290 * keyboard.c (kbd_buffer_get_event):
291 Don't reestablish signal handler; not needed with sigaction.
292 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
294 Rework to avoid unnecessary accesses to volatile variables.
295 (UNBLOCK_INPUT_TO): Now a function.
296 (totally_unblock_input, unblock_input): New decls.
297 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
298 (init_data): Remove. Necessary stuff now done in init_signal.
299 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
300 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
301 (fatal_error_code): Remove; no longer needed.
302 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
303 it doesn't always backtrace. All uses changed. No need to reset
304 signal to default, since sigaction and/or die does that for us now.
305 Use emacs_raise (FOO), not kill (getpid (), FOO).
306 (main): Check more-accurately whether we're dumping.
307 Move fatal-error setup to sysdep.c
308 * floatfns.c: Do not include "syssignal.h"; no longer needed.
309 * gtkutil.c (xg_get_file_name, xg_get_font):
310 Remove no-longer-needed signal-mask manipulation.
311 * keyboard.c, process.c (POLL_FOR_INPUT):
312 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
313 * keyboard.c (read_avail_input): Remove.
314 All uses replaced by gobble_input.
315 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
316 (kbd_buffer_store_event_hold, gobble_input):
317 (record_asynch_buffer_change) [USABLE_SIGIO]:
318 (store_user_signal_events):
319 No need to mess with signal mask.
320 (gobble_input): If blocking input and there are terminals, simply
321 set pending_signals to 1 and return. All hooks changed to not
322 worry about whether input is blocked.
323 (process_pending_signals): Clear pending_signals before processing
324 them, in case a signal comes in while we're processing.
325 By convention callers now test pending_signals before calling us.
326 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
327 New functions, to support changes to blockinput.h.
328 (handle_input_available_signal): Now extern.
329 (reinvoke_input_signal): Remove. All uses replaced by
331 (quit_count): Now volatile, since a signal handler uses it.
332 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
333 All callers changed. Block SIGINT only if not already blocked.
334 Clear sigmask reliably, even if Fsignal returns, which it can.
335 Omit unnecessary accesses to volatile var.
336 (quit_throw_to_read_char): No need to restore sigmask.
337 * keyboard.c (gobble_input, handle_user_signal):
338 * process.c (wait_reading_process_output):
339 Call signal-handling code rather than killing ourselves.
340 * lisp.h: Include <float.h>, for...
341 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
342 (pending_signals): Now volatile.
343 (syms_of_data): Now const if IEEE floating point.
344 (handle_input_available_signal) [USABLE_SIGIO]:
345 (terminate_due_to_signal, record_child_status_change): New decls.
346 * process.c (create_process): Avoid disaster if memory is exhausted
347 while we're processing a vfork, by tightening the critical section
349 (send_process_frame, process_sent_to, handle_pipe_signal)
350 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
352 (send_process): No need for setjmp/longjmp any more, since the
353 SIGPIPE stuff is now gone. Instead, report an error if errno
355 (record_child_status_change): Now extern. PID and W are now args.
356 Return void, not bool. All callers changed.
357 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
358 Remove. All uses removed. This bug should be fixed now in a
360 (wait_for_termination_1): Use waitpid rather than sigsuspend,
361 and record the child status change directly. This avoids the
362 need to futz with the signal mask.
363 (process_fatal_action): Move here from emacs.c.
364 (emacs_sigaction_flags): New function, containing
365 much of what used to be in emacs_sigaction_init.
366 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
367 caught by emacs, to make races less likely.
368 (deliver_process_signal): Rename from handle_on_main_thread.
370 (BACKTRACE_LIMIT_MAX): Now at top level.
371 (thread_backtrace_buffer, threadback_backtrace_pointers):
373 (deliver_thread_signal, deliver_fatal_thread_signal):
374 New functions, for more-accurate delivery of thread-specific signals.
375 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
376 (deliver_arith_signal): Handle in this thread, not
377 in the main thread, since it's triggered by this thread.
378 (maybe_fatal_sig): New function.
379 (init_signals): New arg DUMPING so that we can be more accurate
380 about whether we're dumping. Caller changed.
381 Treat thread-specific signals differently from process-general signals.
382 Block all signals while handling fatal error; that's safer.
383 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
385 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
386 Ignore SIGPIPE unless batch.
387 (emacs_backtrace): Output backtrace for the appropriate thread,
388 which is not necessarily the main thread.
389 * syssignal.h: Include <stdbool.h>.
390 (emacs_raise): New macro.
391 * xterm.c (x_connection_signal): Remove; no longer needed
392 now that we use sigaction.
393 (x_connection_closed): No need to mess with sigmask now.
394 (x_initialize): No need to reset SIGPIPE handler here, since
395 init_signals does this for us now.
397 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
399 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
400 background rect may be larger (Bug#12245).
402 2012-09-23 Chong Yidong <cyd@gnu.org>
404 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
406 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
408 * .gdbinit: Just stop at fatal_error_backtrace.
409 See Stefan Monnier's request in
410 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
411 Remove no-longer-used query of system type.
413 2012-09-22 Chong Yidong <cyd@gnu.org>
415 * search.c (Freplace_match): Doc fix (Bug#12325).
417 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
419 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
420 (Fline_end_position): Doc fix.
422 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
424 2012-09-22 Chong Yidong <cyd@gnu.org>
426 * dispextern.h (struct image_type): Add new slot, storing a type
427 initialization function.
429 * image.c (define_image_type): Call the image initializer function
430 if it is defined. Arguments and return value changed.
431 (valid_image_p, make_image): Callers changed.
432 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
433 (gif_type, imagemagick_type, svg_type, gs_type):
434 Add initialization functions.
435 (Finit_image_library): Call lookup_image_type.
436 (CHECK_LIB_AVAILABLE): Macro deleted.
437 (lookup_image_type): Call define_image_type here, rather than via
438 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
439 (syms_of_image): Move define_image_type calls for xbm_type and
440 pbm_type to lookup_image_type.
442 2012-09-22 Eli Zaretskii <eliz@gnu.org>
444 * keyboard.c (timer_check_2): Move calculation of 'timers' and
445 'idle_timers' from here ...
446 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
447 lists, to avoid infloops when the timer does something stupid,
448 like reinvoke itself with the same or smaller time-out.
451 2012-09-22 Martin Rudalics <rudalics@gmx.at>
453 * window.c (Fsplit_window_internal): Handle only Qt value of
454 Vwindow_combination_limit separately.
455 (Qtemp_buffer_resize): New symbol.
456 (Vwindow_combination_limit): New default value.
459 2012-09-22 Eli Zaretskii <eliz@gnu.org>
461 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
462 the new overlay string. (Bug#10159)
464 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
466 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
467 or that fprintf is async-signal-safe. POSIX doesn't require
470 2012-09-22 Chong Yidong <cyd@gnu.org>
472 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
475 2012-09-22 Kenichi Handa <handa@gnu.org>
477 * composite.c (composition_reseat_it): Handle the case that a
478 grapheme cluster is not covered by a single font (Bug#12352).
480 2012-09-21 Chong Yidong <cyd@gnu.org>
482 * image.c (define_image_type): Avoid adding duplicate types to
483 image_types (Bug#12463). Suggested by Jörg Walter.
485 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
487 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
488 (print_load_command_name): Add case LC_DATA_IN_CODE.
489 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
491 2012-09-21 Glenn Morris <rgm@gnu.org>
493 * eval.c (Frun_hook_with_args_until_success)
494 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
496 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
498 * fileio.c (Ffile_selinux_context): Only call freecon when
499 lgetfilecon succeeded.
500 (Fset_file_selinux_context): Likewise. (Bug#12444)
502 2012-09-21 Eli Zaretskii <eliz@gnu.org>
504 * xdisp.c (try_window_reusing_current_matrix): Under bidi
505 reordering, locate the cursor by calling set_cursor_from_row; if
506 that fails, clear the desired glyph matrix before returning a
507 failure indication to the caller. Fixes leaving garbled display
508 when fast scrolling with a down-key. (Bug#12403)
509 (compute_stop_pos_backwards): Fix a typo that caused crashes while
510 scrolling through multibyte text.
512 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
514 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
515 calling mark_vectorlike since that's the one that marks the window.
516 (mark_discard_killed_buffers): Mark the final cdr.
517 * window.h (struct window): Move prev/next_buffers to the
519 * window.c (make_window): Initialize prev/next_buffers manually.
521 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
523 Omit unused arg EXPECTED from socket hooks.
524 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
525 * nsterm.m (ns_term_init):
526 * termhooks.h (struct terminal.read_socket_hook):
527 * w32inevt.c (w32_console_read_socket):
528 * w32term.c (w32_read_socket):
529 * xterm.c (XTread_socket):
530 Omit unused arg EXPECTED. All callers changed.
531 (store_user_signal_events): Return void, not int, since callers no
532 longer care about the return value. All uses changed.
534 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
536 * w32gui.h (XParseGeometry): Do not declare.
538 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
540 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
541 Ignore 'expected'. See Eli Zaretskii in
542 <http://bugs.gnu.org/12471#8> (last line).
544 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
545 (XParseGeometry): Now static. Substitute extremal values for
546 values that are out of range.
548 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
550 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
552 * nsfns.m (XParseGeometry): Remove.
553 (Fx_create_frame): Call x_set_offset to correctly interpret
556 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
557 (Fx_parse_geometry): If there is a space in string, call
558 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
560 2012-09-17 Eli Zaretskii <eliz@gnu.org>
562 * search.c (scan_buffer): Use character positions in calls to
563 region_cache_forward and region_cache_backward, not byte
564 positions. (Bug#12196)
566 * w32term.c (w32_read_socket): Set pending_signals to 1, like
567 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
569 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
570 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
571 emacs_blocked_malloc, now deleted.
573 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
575 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
576 The workaround was for improving performance on Solaris 2.4, but
577 is getting in the way now. Emacs will still work if someone is
578 still running Solaris 2.4 in a museum somewhere; Sun dropped
579 support for Solaris 2.4 in 2003.
580 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
581 * process.c (create_process) [HAVE_WORKING_VFORK]:
582 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
583 since Emacs no longer uses vfork on that platform.
585 2012-09-17 Glenn Morris <rgm@gnu.org>
587 * emacs.c: Use COPYRIGHT.
589 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
591 Remove configure's --without-sync-input option (Bug#12450).
592 When auditing signal-handling in preparation for cleaning it up,
593 I found that SYNC_INPUT has race conditions and would be a real
594 pain to fix. Since it's an undocumented and deprecated
595 configure-time option, now seems like a good time to remove it.
596 Also see <http://bugs.gnu.org/11080#16>.
597 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
598 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
599 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
601 (check_depth) [XMALLOC_OVERRUN_CHECK]:
602 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
603 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
604 (dont_register_blocks, bytes_used_when_reconsidered)
605 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
606 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
607 [!SYSTEM_MALLOC && !SYNC_INPUT]:
608 Remove. All uses removed.
609 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
610 implementation, one that depends on whether the new macro
611 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
613 * atimer.c (run_timers, handle_alarm_signal):
614 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
615 (handle_async_input, process_pending_signals)
616 (handle_input_available_signal, init_keyboard):
617 * nsterm.m (ns_read_socket):
618 * process.c (wait_reading_process_output):
619 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
620 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
622 * xterm.c (XTread_socket):
624 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
625 * eval.c (handling_signal): Remove. All uses removed.
626 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
627 All uses replaced with the SYNC_INPUT version.
628 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
630 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
633 * font.c (Ffont_shape_gstring): Remove unused local.
635 2012-09-16 Glenn Morris <rgm@gnu.org>
637 * Makefile.in (clean): No longer run nextstep's clean.
639 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
641 (ns-app): Move here from ns.mk, and simplify.
642 (clean): Simplify nextstep entry.
643 * ns.mk: Remove file.
645 2012-09-17 Kenichi Handa <handa@gnu.org>
647 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
648 not covert the last few charactes.
650 2012-09-16 Kenichi Handa <handa@gnu.org>
652 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
653 here, but just check the validity of glyphs in the glyph-string.
655 2012-09-16 Martin Rudalics <rudalics@gmx.at>
657 * window.c (Fwindow_parameter, Fset_window_parameter):
658 Accept any window as argument (Bug#12452).
660 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
662 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
663 to ns_term_init to avoid memory leak.
665 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
666 explicit retain/release.
667 (ns_term_init): Only allow one display. Initialize outerpool and
670 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
672 Port _setjmp fix to POSIXish hosts as well as Microsoft.
673 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
674 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
675 the Microsoft problem in a different way, by altering ../nt/config.nt.
677 2012-09-15 Eli Zaretskii <eliz@gnu.org>
692 * w16select.c: Remove inclusion of setjmp.h, as it is now included
693 by lisp.h. This completes removal of setjmp.h inclusion
694 erroneously announced in the previous commit. (Bug#12446)
696 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
699 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
700 not defined as a macro. The latter happens on MS-Windows.
703 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
705 Port better to POSIX hosts lacking _setjmp (Bug#12446).
706 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
707 Some instances of '#include <setjmp.h>' removed, if the
708 only reason for the instance was because "lisp.h" was included.
709 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
710 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
711 and _longjmp with the new symbols. Emacs already uses _setjmp if
712 available, so this change affects only POSIXish hosts that have
713 sigsetjmp but not _setjmp, such as some versions of Solaris and
714 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
715 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
716 (png_load_body) [HAVE_PNG]:
717 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
718 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
719 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
720 since PNG requires jmp_buf. This is the only exception to the
721 general rule that we now use sys_setjmp and sys_longjmp.
722 This exception is OK since this code does not change the signal
723 mask or longjmp out of a signal handler.
725 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
727 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
728 Include "syssignal.h", for 'main_thread'.
730 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
732 Avoid out-of-range marker position (Bug#12426).
733 * insdel.c (replace_range, replace_range_2):
734 Adjust markers before overlays, as suggested by comments.
735 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
736 Remove redundant check before calling offset_intervals.
738 2012-09-14 Martin Rudalics <rudalics@gmx.at>
740 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
741 current buffer (Bug#12387).
743 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
745 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
747 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
749 Use a more backwards-compatible timer format (Bug#12430).
750 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
751 vector element, not from the 4th, since PSECS is now at the end.
752 (Fcurrent_idle_time): Doc fix.
754 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
756 Function to mark objects and remove killed buffers at once.
757 * alloc.c (discard_killed_buffers): Rename to ...
758 (mark_discard_killed buffers) ... new name. Add marking
759 of remaining objects. Fix comment. Adjust users.
760 (mark_object): Do not touch frame buffer lists here.
761 * frame.c (delete_frame): Reset frame buffer lists here.
763 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
765 Better workaround for GNOME bug when --enable-gcc-warnings.
766 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
767 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
768 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
770 Simplify SIGIO usage (Bug#12408).
771 The code that dealt with SIGIO was crufty and confusing, e.g., it
772 played tricks like "#undef SIGIO" but these tricks were not used
773 consistently. Simplify mostly by not #undeffing standard symbols,
774 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
775 or not as we please) rather than "defined SIGIO" (standard symbol
776 that we probably shouldn't #undef).
777 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
778 Modules that need it can include it.
779 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
780 * dispextern.h (ignore_sigio): New decl.
781 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
782 unconditionally, since it's now a no-op if !USABLE_SIGIO.
783 * emacs.c (shut_down_emacs):
784 * keyboard.c (kbd_buffer_store_event_hold):
785 Use ignore_sigio rather than invoking 'signal' directly.
786 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
788 (FIONREAD, SIGIO): Do not #undef.
789 (tty_read_avail_input): Use #error rather than a syntax error.
790 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
791 for I_PIPE, used by SETUP_SLAVE_PTY.
792 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
793 * sysdep.c (croak): Remove; no longer needed. This bit of
794 temporary code, with Fred N. Fish's comment that it's temporary,
795 has been in Emacs since at least 1992!
796 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
797 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
798 * syssignal.h (croak): Remove decl.
799 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
800 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
801 now that we're termios-only.
802 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
803 * term.c (dissociate_if_controlling_tty): Use #error rather than
806 Work around GCC and GNOME bugs when --enable-gcc-warnings.
807 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
808 to work around GNOME bug 683906.
809 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
810 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
811 This works around GCC bug 54561.
813 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
815 More fixes for 'volatile' and setjmp/longjmp.
816 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
817 * image.c (struct png_load_context) [HAVE_PNG]: New type.
818 (png_load_body) [HAVE_PNG]:
819 (jpeg_load_body) [HAVE_JPEG]:
820 New function, with most of the old parent function's body.
821 (png_load) [HAVE_PNG]:
822 (jpeg_load) [HAVE_JPEG]:
823 Invoke the new function, to avoid longjmp munging our locals.
824 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
825 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
826 longjmp is passed 2, as the C standard doesn't guarantee this.
827 Instead, store the failure code into mgr->failure_code.
829 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
831 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
832 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
833 (syms_of_keyboard): Remove support for unread-command-char.
835 2012-09-12 Eli Zaretskii <eliz@gnu.org>
837 * w32proc.c (sys_kill): If PID is our process ID and the signal is
838 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
839 violation. (Bug#12426)
841 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
843 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
845 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
847 * eval.c: Add `inhibit-debugger'.
848 (Qinhibit_debugger): New symbol.
849 (call_debugger): Bind it instead of Qdebug_on_error.
850 (maybe_call_debugger): Test Vinhibit_debugger.
851 (syms_of_eval): Define inhibit-debugger.
852 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
853 (syms_of_xdisp): Remove inhibit-debug-on-message.
855 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
857 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
858 If a nonvolatile local variable is written before a _longjmp to
859 the frame containing the variable, and is read after the _longjmp,
860 the value read is indeterminate. Some local variables of type
861 'struct handler' and 'struct catchtag' are used in this way, so
862 mark each of their slots as volatile if the slot can be set before
863 _longjmp and read afterwards.
864 * lisp.h (struct handler): var and chosen_clause are now volatile.
865 (struct catchtag): val, next, and pdlcount are now volatile.
867 * bidi.c (bidi_push_it, bidi_pop_it):
868 * fns.c (copy_hash_table):
869 * image.c (define_image_type):
870 * keyboard.c (kbd_buffer_store_event_hold):
871 * process.c (Fprocess_send_eof):
872 * xfaces.c (x_create_gc) [HAVE_NS]:
873 * xgselect.c (xg_select):
874 Prefer assignment to memcpy when either will do.
876 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
877 Use pointer-to-a-pointer to simplify and avoid a NILP check each
878 time an item is removed. No need to mark this function 'inline';
879 the compiler knows better than we do.
881 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
883 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
884 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
885 to change_frame_size (Bug#12388).
886 (windowDidResize:): Pass YES to updateFrameSize.
888 * nsterm.h: Add delay parameter to updateFrameSize.
890 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
892 Discard killed buffers from deleted window and frame objects.
893 This reduces an amount of references to killed buffers and
894 helps GC to reclaim them faster.
895 * alloc.c (discard_killed_buffers): New function.
896 (mark_object): Use it for deleted windows and frames.
897 (mark_object): If symbol's value is set up for a killed buffer
898 or deleted frame, restore it's global binding.
899 * data.c (swap_in_global_binding): Add GC notice.
900 (swap_in_symval_forwarding): Use convenient set_blv_where.
901 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
902 * window.h: ... to here.
904 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
906 Convenient macro to check whether the buffer is live.
907 * buffer.h (BUFFER_LIVE_P): New macro.
908 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
909 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
911 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
913 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
914 composition cases (Bug#12364).
916 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
917 overhang of succeeding glyphs overlapping box cursor.
919 * w32term.c (x_draw_glyph_string): Likewise.
921 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
923 Simplify, document, and port floating-point (Bug#12381).
924 The porting part of this patch fixes bugs on non-IEEE platforms
925 with frexp, ldexp, logb.
926 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
928 * floatfns.c: Simplify discussion of functions that Emacs doesn't
929 support, by removing commented-out code and briefly listing the
930 C89 functions excluded. The commented-out stuff was confusing
931 maintenance, e.g., we thought we needed cbrt but it was commented out.
932 (logb): Remove decl; no longer needed.
933 (isfinite): New macro, if not already supplied.
934 (isnan): Don't replace any existing macro.
935 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
936 are present on all C89 platforms.
937 (Ffrexp): Do not special-case zero, as frexp does the right thing
939 (Flogb): Do not use logb, as it doesn't have the desired meaning
940 on hosts that use non-base-2 floating point. Instead, stick with
941 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
942 frexp, to avoid getting an unspecified result.
944 * xdisp.c (Qinhibit_debug_on_message): Now static.
946 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
948 * nsterm.m (ns_update_begin): Set clip path to whole view by using
949 NSBezierPath (Bug#12131).
951 2012-09-10 Chong Yidong <cyd@gnu.org>
953 * fns.c (Fdelq, Fdelete): Doc fix.
955 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
957 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
958 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
960 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
962 * lisp.h (make_lisp_ptr): New macro to replace XSET.
963 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
966 2012-09-09 Eli Zaretskii <eliz@gnu.org>
968 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
969 left fringe if the window has a left margin. This avoids leaving
970 traces of the cursor because its leftmost pixel is not drawn over.
972 * dispnew.c (update_window_line): When the left margin area of a
973 screen line is updated, set the redraw_fringe_bitmaps_p flag of
974 that screen line. (Bug#12277)
976 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
978 Assume C89 or later for math functions (Bug#12381).
979 This simplifies the code, and makes it a bit smaller and faster,
980 and (most important) makes it easier to clean up signal handling
981 since we can stop worring about floating-point exceptions in
982 library code. That was a problem before C89, but the problem
983 went away many years ago on all practical Emacs targets.
984 * data.c, image.c, lread.c, print.c:
985 Don't include <math.h>; no longer needed.
986 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
987 might be autoconfigured, as that never happens.
989 * doprnt.c (DBL_MAX_10_EXP):
991 Remove. C89 or later always defines these.
992 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
993 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
994 (arith_error, domain_error, domain_error2):
995 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
996 no longer needed -- we simply return what C returns. All uses removed.
997 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
999 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
1000 Remove. All uses expanded, as these macros are no longer used
1001 more than once and are now more trouble than they're worth.
1002 (Ftan): Use tan, not sin / cos.
1003 (Flogb): Assume C89 frexp.
1004 (fmod_float): Assume C89 fmod.
1005 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
1006 (init_floatfns): Remove. All uses removed.
1008 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1010 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
1011 compositeToPoint for OSX < 10.6 (Bug#12390).
1013 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
1015 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
1016 This produces more-accurate results.
1018 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1020 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
1021 changes (Bug#12088).
1023 2012-09-08 Chong Yidong <cyd@gnu.org>
1025 * syntax.c (Fstring_to_syntax): Doc fix.
1027 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1029 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
1030 in the internal border.
1031 (x_set_window_size): Remove static variables and their usage.
1032 (ns_redraw_scroll_bars): Fix NSTRACE arg.
1033 (ns_after_update_window_line, ns_draw_fringe_bitmap):
1034 Remove fringe/internal border adjustment (Bug#11052).
1035 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
1036 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
1037 (ns_fix_rect_ibw): Remove.
1038 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
1039 (ns_dumpglyphs_box_or_relief): Ditto.
1040 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
1042 (ns_dumpglyphs_image): Ditto.
1043 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
1045 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
1046 their usage. Add fringe_extended_p and its use as in other terms.
1047 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
1048 scroll bar was removed.
1049 (updateFrameSize): New function.
1050 (windowDidResize): Move code to updateFrameSize and call it.
1052 * nsterm.h (EmacsView): Add updateFrameSize.
1054 2012-09-07 Chong Yidong <cyd@gnu.org>
1056 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
1058 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
1060 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1062 More signal-handler cleanup (Bug#12327).
1063 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
1064 Problem introduced when merging patches. Noted by Eli Zaretskii in
1065 <http://bugs.gnu.org/12327#67>.
1066 * floatfns.c: Comment fix.
1067 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
1068 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
1069 and anyway the declaration is harmless even if SIGDANGER is not defined.
1070 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
1071 defined BROKEN_FIONREAD). systty.h formerly did this, but other
1072 source files not surprisingly expected syssignal.h to define, or
1073 not define, SIGIO, and it's cleaner to do it that way, for consistency.
1074 Include <sys/ioctl.h>, for FIONREAD.
1075 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
1076 This eliminates a problem whereby other files mysteriously had
1077 to include "syssignal.h" before including "systty.h" if they
1078 wanted to use "#ifdef SIGIO".
1080 2012-09-07 Eli Zaretskii <eliz@gnu.org>
1082 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
1084 * w32.c (sigemptyset): Empty the set.
1085 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
1087 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
1089 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
1091 * alloc.c (mark_buffer): Revert unsafe marking optimization.
1092 (mark_object): Likewise for frame objects.
1094 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1096 * syssignal.h (handle_on_main_thread): Always declare,
1097 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
1098 This ports to platforms without HAVE_PTHREAD.
1100 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1102 Signal-handler cleanup (Bug#12327).
1103 Emacs's signal handlers were written in the old 4.2BSD style with
1104 sigblock and sigmask and so forth, and this led to some
1105 inefficiencies and confusion. Rewrite these to use
1106 pthread_sigmask etc. without copying signal sets around. Also,
1107 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
1108 'signal', and instead use functions that do not attempt to take
1109 over the system name space. This patch causes Emacs's text
1110 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
1111 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
1112 Do not include <signal.h> or "syssignal.h", as these
1113 modules do not use signals.
1114 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
1115 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
1116 Do not include <signal.h>, as "syssignal.h" does that for us now.
1117 * atimer.c (sigmask_atimers): New function.
1118 (block_atimers, unblock_atimers): New functions,
1119 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
1121 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
1122 no longer needed here.
1123 * emacs.c (main): Inspect existing signal handler with sigaction,
1124 so that there's no need to block and unblock SIGHUP.
1125 * sysdep.c (struct save_signal): New member 'action', replacing
1126 old member 'handler'.
1127 (save_signal_handlers, restore_signal_handlers):
1128 Use sigaction instead of 'signal' to save and restore.
1129 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
1130 New function. All users of 'signal' modified to use set_sighandler
1131 if they're writeonly, and to use sys_signal if they're read+write.
1132 (emacs_sigaction_init, forwarded_signal): New functions.
1133 (sys_signal): Remove. All uses replaced by calls to sigaction
1134 and emacs_sigaction_init, or by direct calls to 'signal'.
1135 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
1136 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
1137 all uses replaced by pthread_sigmask etc. calls.
1138 * syssignal.h: Include <signal.h>.
1139 (emacs_sigaction_init, forwarded_signal): New decls.
1140 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
1141 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
1142 (sigmask, sys_sigmask): Remove; no longer needed.
1143 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
1144 (sigblock, sigunblock, sigfree):
1145 (sigsetmask) [!defined sigsetmask]:
1146 Remove. All uses replaced by pthread_sigmask.
1147 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
1148 no longer need to be replaced, and its typical old uses
1149 are now done via emacs_sigaction_init and sigaction.
1150 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
1151 (sys_sigdel): Remove; unused.
1152 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
1154 2012-09-06 Eli Zaretskii <eliz@gnu.org>
1156 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
1157 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
1159 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1161 Explicitly mark buffer_defaults and buffer_local_symbols.
1162 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
1163 mark_local_symbols here.
1164 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
1165 since special buffers aren't marked here any more.
1166 (allocate_buffer): Chain new buffer with all_buffers here...
1167 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
1169 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
1170 (syms_of_buffer): Remove staticpro of the above.
1171 (init_buffer_once): Set names for buffer_defaults and
1172 buffer_local_symbols.
1174 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1176 Use bool for booleans in font-related modules.
1177 * font.c (font_intern_prop, font_style_to_value)
1178 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
1179 (generate_otf_features, font_check_otf_features, font_check_otf)
1180 (font_match_p, font_list_entities, font_at):
1181 * fontset.c (fontset_id_valid_p, reorder_font_vector
1182 (fontset_find_font, Fset_fontset_font)
1183 (face_suitable_for_char_p) [0]:
1184 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
1185 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
1186 (m17n_flt_initialized, ftfont_shape_by_flt):
1187 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
1188 * nsfont.m (nsfont_draw):
1189 * w32font.c (w32font_draw):
1190 * w32term.c (x_draw_glyphless_glyph_string_foreground):
1191 Use bool for booleans.
1192 * font.h: Adjust to above API changes.
1193 (struct font, struct font_driver, struct font_driver_list):
1194 Use bool for booleans.
1195 (struct font): Remove useless member encoding_type.
1197 * fontset.c, xftfont.c: Omit unnecessary static decls.
1199 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1201 * alloc.c (mark_object): Revert window marking code
1202 since it's unsafe for the Fset_window_configuration.
1204 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1206 Fix race conditions with signal handlers and errno (Bug#12327).
1207 Be more systematic about preserving errno whenever a signal
1208 handler returns, even if it's not in the main thread. Do this by
1209 renaming signal handlers to distinguish between signal delivery
1210 and signal handling. All uses changed.
1211 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
1212 * data.c (deliver_arith_signal): Rename from arith_error.
1213 * dispnew.c (deliver_window_change_signal): Rename from
1214 window_change_signal.
1215 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
1216 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
1217 * keyboard.c (deliver_input_available_signal): Rename from
1218 input_available_signal.
1219 (deliver_user_signal): Rename from handle_user_signal.
1220 (deliver_interrupt_signal): Rename from interrupt_signal.
1221 * process.c (deliver_pipe_signal): Rename from send_process_trap.
1222 (deliver_child_signal): Rename from sigchld_handler.
1223 * atimer.c (handle_alarm_signal):
1224 * data.c (handle_arith_signal):
1225 * dispnew.c (handle_window_change_signal):
1226 * emacs.c (handle_fatal_signal, handle_danger_signal):
1227 * keyboard.c (handle_input_available_signal):
1228 * keyboard.c (handle_user_signal, handle_interrupt_signal):
1229 * process.c (handle_pipe_signal, handle_child_signal):
1230 New functions, with the actual signal-handling code taken from the
1231 original respective signal handlers, sans the sporadic attempts to
1232 preserve errno, since that's now done by handle_on_main_thread.
1233 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
1234 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
1235 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1237 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1238 Move initialization of main_thread to sysdep.c's init_signals.
1239 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
1240 our usage, and simplifies the mainline code.
1241 (record_child_status_change): New static function, as a helper
1242 for handle_child_signal, and with most of the old child handler's
1244 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
1245 (handle_child_signal): Use the above.
1246 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1247 Moved here from emacs.c.
1248 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
1249 code moved here from emacs.c's main function.
1250 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
1251 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
1252 This lets callers save and restore errno properly.
1254 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1256 Remove redundant or unused things here and there.
1257 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
1258 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
1259 * editfns.c (Fcompare_buffer_substrings): Likewise.
1260 * frame.h (struct terminal, struct font_driver_list):
1261 Remove redundant declarations.
1262 * window.h (Qleft, Qright): Likewise.
1264 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1266 Do not mark objects from deleted buffers, windows and frames.
1267 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
1268 (mark_object): Likewise for windows and frames.
1270 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1272 * alloc.c (valid_lisp_object_p): Treat killed buffers,
1273 buffer_defaults and buffer_local_symbols as valid objects.
1274 Return special value to denote them.
1276 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1278 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
1279 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
1280 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
1281 (file_name_absolute_p, Fsubstitute_in_file_name):
1282 (check_executable, check_writable, Ffile_accessible_directory_p)
1283 (Fset_file_selinux_context, Fdefault_file_modes)
1284 (Finsert_file_contents, choose_write_coding_system)
1285 (Fwrite_region, build_annotations, a_write, e_write)
1287 * filelock.c (boot_time_initialized, get_boot_time)
1288 (get_boot_time_1, lock_file_1, within_one_second):
1289 * floatfns.c (in_float):
1290 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
1291 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
1292 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
1293 * lisp.h (struct Lisp_Hash_Table.cmpfn):
1294 * window.c (compare_window_configurations):
1295 Use bool for booleans.
1296 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
1297 (Fdefault_file_modes): Now mode_t, not int, for modes.
1298 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
1299 (internal_delete_file): Now returns void, not a (boolean) int,
1300 since nobody was looking at the return value.
1301 * lisp.h, window.h: Adjust to above API changes.
1303 * xdisp.c (set_message): Simplify and reindent last change.
1305 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
1307 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
1309 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
1311 * eval.c (call_debugger): Make the function non-static so that we
1312 can call it from set_message.
1314 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
1315 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
1317 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1319 Give more-useful info on a fatal error (Bug#12328).
1320 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
1321 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
1322 of doing the work ourselves.
1323 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
1324 do most of the work.
1325 (fatal_error_backtrace): New function, taken from the guts
1326 of the old fatal_error_signal, but with a new option to output
1328 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
1329 info about the signal than just its number.
1330 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
1331 * sysdep.c: Include <execinfo.h>
1332 (emacs_backtrace): New function, taken partly from the previous
1333 code of the 'die' function.
1334 (emacs_abort): Call fatal_error_backtrace rather than abort.
1336 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
1338 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
1339 eager (load-time) macro-expansion.
1340 * lisp.mk (lisp): Add macroexp.
1342 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1344 Simplify redefinition of 'abort' (Bug#12316).
1345 Do not try to redefine the 'abort' function. Instead, redo
1346 the code so that it calls 'emacs_abort' rather than 'abort'.
1347 This removes the need for the NO_ABORT configure-time macro
1348 and makes it easier to change the abort code to do a backtrace.
1349 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
1350 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
1351 Remove; sysdep.c's emacs_abort now takes its place.
1352 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
1353 'abort' changed to use 'emacs_abort'.
1354 * msdos.c (dos_abort) [defined abort]: Remove; not used.
1355 (abort) [!defined abort]: Rename to ...
1356 (emacs_abort): ... new name.
1357 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
1358 the place of the old 'abort' in emacs.c.
1359 * w32.c, w32fns.c (abort): Do not #undef.
1360 * w32.c (emacs_abort): Rename from w32_abort.
1362 2012-09-04 Eli Zaretskii <eliz@gnu.org>
1364 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
1365 offsets[j].dv, since the y axis of the screen coordinates points
1366 down, while the y axis of the font definition coordinates points
1367 up. This fixes display of Arabic diacritics such as KASRA and
1368 KASRATAN. (Bug#11860)
1370 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1372 Be more systematic about _setjmp vs setjmp.
1373 * alloc.c (test_setjmp, mark_stack):
1374 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
1375 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
1376 (png_load, my_error_exit, jpeg_load):
1377 * process.c (send_process_trap, send_process):
1378 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
1379 The underscored versions are up to 30x faster on some hosts.
1380 Formerly, the code used setjmp+longjmp sometimes and
1381 _setjmp+_longjmp at other times, with no particular reason to
1382 prefer setjmp+longjmp.
1384 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
1386 Fix minor problem found by static checking.

1413 EXCLUDE_SUBRS_P. All callers changed.
1414 * dispextern.h, lisp.h: Reflect above API changes.
1415 * firstfile.c (dummy): Use the address of 'main', whose signature
1416 won't change, instead of the address of 'initialize', whose
1417 signature just changed from int to bool.
1418 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
1419 * msdos.c (fatal_error_in_progress): ... from here.
1420 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
1422 (redisplay_internal, unwind_redisplay): Simply clear
1423 REDISPLAYING_P when unwinding, instead of saving its previous,
1424 always-false value and then restoring it.
1426 Clean up some extern decls.
1427 Mostly, this hoists extern decls out of .c files and into .h files.
1428 That way, we're more likely to catch errors if the interfaces change.
1429 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
1430 declare xg_mark_data.
1431 * dispextern.h (x_frame_parm_handlers):

1451 Remove now-redundant extern decls.
1452 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
1453 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
1455 * xfaces.c: Remove unnecessary static decls.
1456 * xterm.c (updating_frame): Remove decl of nonexistent object.
1458 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
1459 when building globals.h, as the objects that are not built on
1460 this host are not needed to compile C files on this host.
1462 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
1464 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

1491 (set_intervals_multibyte_1, set_intervals_multibyte):
1492 * keyboard.c (decode_timer):
1493 Use bool for boolean.
1494 * intervals.h, lisp.h, systime.h: Reflect above API changes.

1512 2012-09-01 Eli Zaretskii <eliz@gnu.org>
1514 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
1515 more than one grapheme cluster passed to the shaper: compute the
1516 offset adjustment values separately for each cluster. (Bug#11860)
1518 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1519 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1520 about implicit conversions from integer to pointer.
1522 2012-09-01 Daniel Colascione <dancol@dancol.org>
1524 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
1525 system used too early.
1527 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
1529 Better seed support for (random).

1574 window-system headers. Declare Vlibrary_cache when compiling for
1577 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
1578 window system declarations.
1580 * frame.h: Move common functions here: set_frame_menubar,
1581 x_set_window_size, x_sync, x_get_focus_frame,
1582 x_set_mouse_position, x_set_mouse_pixel_position,
1583 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

1610 * lisp.h (mark_ttys): Remove prototype.
1611 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call

1644 * lread.c (init_lread): For out-of-tree builds, only add the
1645 source directory's site-lisp dir to the load-path if it exists,
1646 consistent with in-tree builds. (Bug#12302)

1667 Handle click on close button as quit.
1669 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
1670 Add window_closed and button_values. Add void as return value for
1671 add(Button|String|Split). addButton takes int instead of Lisp_Object.
1672 Add process_dialog as new member.
1674 2012-08-28 Eli Zaretskii <eliz@gnu.org>
1676 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

1810 * coding.h, lisp.h: Reflect above API changes.
1811 * coding.c: Remove unnecessary static function decls.
1812 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
1813 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
1814 not a boolean 'int', since callers never look at the return value.
1815 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
1816 * coding.h (decoding_buffer_size, encoding_buffer_size)
1817 (emacs_mule_string_char): Remove unused extern decls.
1818 (struct iso_2022_spec, struct coding_system):
1819 Use 'unsigned int : 1' for boolean fields, since there's more than one.
1820 (struct emacs_mule_spec): Remove unused field 'full_support'.
1821 All initializations removed.
1822 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
1824 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
1826 Fix spare memory change (Bug#12286).
1827 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
1828 (valid_lisp_object_p): Likewise.
1830 2012-08-27 Martin Rudalics <rudalics@gmx.at>
1832 * window.c (Fset_window_configuration): Record any window's old
1833 buffer if it's replaced (see Bug#8789). If the new current
1834 buffer doesn't appear in the selected window, go to its old
1837 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
1839 Special MEM_TYPE_SPARE to denote reserved memory.
1840 * alloc.c (enum mem_type): New memory type.
1841 (refill_memory_reserve): Use new type for spare memory.
1842 This prevents live_cons_p and live_string_p from incorrect
1843 detection of uninitialized objects from spare memory as live.
1845 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
1848 * Makefile.in (.PHONY): versioclean -> versionclean.
1850 Remove unused external symbols.
1851 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
1852 * window.c (Qwindow_valid_p, decode_valid_window):
1853 Now static, not extern.
1854 * data.c (Qinterval): Remove; unused.
1855 (syms_of_data): Do not define 'interval'.
1856 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
1857 * window.h (decode_valid_window):
1860 * character.c, charset.c, chartab.c: Use bool for booleans.
1861 * character.c (lisp_string_width, string_count_byte8)
1862 (string_escape_byte8):
1863 * charset.c (charset_map_loaded, load_charset_map, read_hex):
1864 (load_charset_map_from_file, map_charset_chars)
1865 (Fdefine_charset_internal, define_charset_internal)
1866 (Fdeclare_equiv_charset, find_charsets_in_text)
1867 (Ffind_charset_region, char_charset, Fiso_charset):
1868 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
1869 (sub_char_table_set, sub_char_table_set_range)
1870 (char_table_set_range, optimize_sub_char_table)
1871 (map_sub_char_table):
1872 Use bool for boolean.
1873 * character.c (str_to_unibyte): Omit last boolean argument; it was
1874 always 0. All callers changed.
1875 * character.h, charset.h: Adjust to match previous changes.
1876 * character.h (char_printable_p): Remove decl of nonexistent function.
1877 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
1878 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
1879 are all boolean, so make them single-bit bitfields.
1881 * lisp.h (ASET): Remove attempt to detect side effects.
1882 It was meant to be temporary and it often doesn't work,
1883 because when IDX has side effects the behavior of IDX==IDX
1884 is undefined. See Stefan Monnier in
1885 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
1887 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
1889 * lisp.h (functionp): New function (extracted from Ffunctionp).
1890 (FUNCTIONP): Use it.
1891 * eval.c (Ffunctionp): Use it.
1893 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1895 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
1896 as that's faster and simpler than static storage. Don't bother
1897 with the g_main_context_query overhead if g_main_context_pending
1898 says no events are pending.
1899 (gfds, gfds_size): Remove these static vars.
1900 (xgselect_initialize): Remove; no longer needed.
1901 All uses and decls removed.
1903 * emacs.c (fatal_error_signal_hook): Remove.
1904 All uses removed. This leftover from old code was always 0.
1906 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
1907 * casefiddle.c (casify_object, casify_region):
1908 * casetab.c (set_case_table):
1909 * category.c, category.h (word_boundary_p):
1910 * category.h (CHAR_HAS_CATEGORY):
1911 Use bool for booleans, instead of int.
1913 2012-08-25 Eli Zaretskii <eliz@gnu.org>
1915 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
1917 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1919 On assertion failure, print backtrace if available.
1920 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1921 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1922 * Makefile.in (LIB_EXECINFO): New macro.
1925 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1926 * bytecode.c (exec_byte_code):
1927 * callint.c (check_mark, Fcall_interactively):
1928 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1929 (getenv_internal, sync_process_alive, call_process_exited):
1930 * lisp.h (USE_SAFE_ALLOCA):
1931 Use bool for booleans, instead of int.
1932 * lisp.h, process.h: Adjust prototypes to match above changes.
1933 * callint.c (Fcall_interactively): Don't assume the mark's
1934 offset fits in 'int'.
1936 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1938 * buffer.c, buffer.h: Use bool for boolean.
1939 * buffer.c (reset_buffer_local_variables)
1940 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1941 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
1942 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
1943 (overlay_touches_p, overlay_strings, Foverlay_put)
1944 (report_overlay_modification, call_overlay_mod_hooks):
1945 (mmap_enlarge, mmap_set_vars):
1946 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1947 Use bool for booleans, instead of int.
1948 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1949 since the 1-or-0 return value is always ignored anyway.
1950 (mmap_initialized_p):
1951 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1952 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1954 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1956 * bidi.c: Use bool for boolean.
1957 This is a bit more readable, and makes the text segment of bidi.o
1958 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1959 Presumably it's faster too.
1960 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1962 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1963 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1964 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1965 (bidi_explicit_dir_char, bidi_level_of_next_char)
1966 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1967 Use bool for booleans, instead of int.
1968 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1969 (bidi_unshelve_cache): Adjust decls to match code.
1971 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1973 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1976 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1978 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1979 * atimer.h: Include <stdbool.h>.
1981 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1983 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1984 compile time tests instead of run time tests on systems that do
1986 (FRAME_MAC_P): Remove leftover from deleted code.
1987 * frame.c (syms_of_frame): Remove leftover from deleted code.
1989 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
1991 * nsterm.m (insertText:): Don't clear modifiers if code is space.
1993 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1995 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1996 Otherwise, the compiler complains about (A?B:C) where B is void
1997 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1998 (fontset_add): Return void, for FONTSET_ADD.
2000 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2002 * alloc.c: Use bool for booleans.
2003 (gc_in_progress, abort_on_gc)
2004 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2005 (dont_register_blocks) [GC_MALLOC_CHECK]:
2006 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
2007 (check_string_bytes, make_specified_string, memory_full)
2008 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
2009 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
2010 (mark_stack, valid_pointer_p, make_pure_string)
2011 (Fgarbage_collect, survives_gc_p, gc_sweep):
2012 Use bool for booleans, instead of int.
2013 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2014 Remove unused local.
2015 * alloc.c (PURE_POINTER_P):
2016 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
2017 * editfns.c (Fformat):
2018 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
2020 * fns.c (sweep_weak_table):
2021 * lisp.h (suppress_checking, push_message, survives_gc_p)
2022 (make_pure_string, gc_in_progress, abort_on_gc):
2023 * lread.c (readchar, read1):
2024 * print.c (Fprin1_to_string):
2025 * xdisp.c (push_message):
2026 Use bool for booleans affected directly or indirectly by
2029 Make recently-introduced setters macros.
2030 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
2031 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
2032 (set_fontset_default, set_fontset_fallback): Rename from their
2033 upper-case counterparts, and make them functions rather than macros.
2034 This is more consistent with the other recently-introduced setters.
2035 These don't need to be inline, since they're local.
2037 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
2039 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
2040 the loop (Bug#12247).
2042 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2044 * lisp.h (vcopy): Use memcpy rather than our own loop.
2045 This fixes a performance regression introduced by the recent
2046 addition of vcopy. This means 'vcopy' will need to be modified
2047 for a copying collector, but that's OK. Also, tighten the
2048 checking in the assertion.
2050 2012-08-21 Eli Zaretskii <eliz@gnu.org>
2052 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
2053 components for RTL text (Bug#11860). Adjust X-OFFSET of each
2054 non-base glyph for the width of the base character, according to
2055 what x_draw_composite_glyph_string_foreground expects.
2056 Generate WADJUST value according to composition_gstring_width's
2057 expectations, to produce correct width of the composed character.
2058 Reverse the sign of the DU offset produced by ScriptPlace.
2060 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2062 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
2064 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2066 Avoid direct writes to contents member of struct Lisp_Vector.
2067 * lisp.h (vcopy): New function to copy data into vector.
2068 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
2069 * fns.c (Ffillarray): Use ASET.
2070 * keyboard.c (timer_check_2): Use AREF and ASET.
2071 (append_tool_bar_item, Frecent_keys): Use vcopy.
2072 * lread.c (read_vector): Use ASET.
2073 * msdos.c (Frecent_doskeys): Use vcopy.
2074 * xface.c (Finternal_copy_lisp_face): Use vcopy.
2075 (Finternal_merge_in_global_face): Use ASET and vcopy.
2076 * xfont.c (xfont_list_pattern): Likewise.
2078 2012-08-21 Martin Rudalics <rudalics@gmx.at>
2080 * window.c (Fwindow_point): For the selected window always return
2081 the position of its buffer's point.
2082 (Fset_window_point): For the selected window always go in its
2083 buffer to the specified position.
2085 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2087 Setter macros for fontsets.
2088 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
2089 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
2090 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
2093 2012-08-20 Glenn Morris <rgm@gnu.org>
2095 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
2096 Don't assume that `ln -f' works.
2098 2012-08-20 Eli Zaretskii <eliz@gnu.org>
2100 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
2101 and later about non-assignments with no effect. See discussion at
2102 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
2105 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2107 Inline setter functions for Lisp_Objects slots of struct specbinding.
2108 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
2111 2012-08-20 Martin Rudalics <rudalics@gmx.at>
2113 * window.c (select_window): Always make selected window's buffer
2116 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2118 Use AREF and ASET for docstrings of category tables.
2119 * category.h (CATEGORY_DOCSTRING): Use AREF.
2120 (SET_CATEGORY_DOCSTRING): Use ASET.
2121 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
2123 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2125 Inline setter functions for hash table members.
2126 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
2127 (set_hash_hash, set_hash_index): Rename with _slot suffix.
2128 (set_hash_key_and_value, set_hash_index, set_hash_next)
2129 (set_hash_hash): New functions.
2130 * charset.c, fns.c: Adjust users.
2132 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2134 Inline getter and setter functions for per-buffer values.
2135 * buffer.h (per_buffer_default, set_per_buffer_default)
2136 (per_buffer_value, set_per_buffer_value): New functions.
2137 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
2138 * buffer.c, data.c: Adjust users.
2140 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
2142 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
2144 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
2146 Rely on <config.h> + <unistd.h> to declare 'environ',
2147 as gnulib does this if the system doesn't.
2148 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
2149 Remove declaration. MS-Windows declares it on stdlib.h which is
2150 included by conf_post.h.
2151 * emacs.c (environ) [DOUG_LEA_MALLOC]:
2152 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
2153 * vm-limit.c: Include <unistd.h>, for 'environ'.
2155 * unexaix.c, unexcoff.c: Include "mem-limits.h".
2156 (start_of_data): Remove decl; mem-limits.h provides it.
2158 * xdisp.c (handle_invisible_prop): Make it a bit faster
2159 and avoid a gcc -Wmaybe-uninitialized diagnostic.
2161 2012-08-19 Chong Yidong <cyd@gnu.org>
2163 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
2166 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
2168 * .gdbinit: Use call instead of set when calling a function in the
2171 * data.c (set_internal): Don't use set_blv_found.
2172 (Fkill_local_variable): Likewise.
2174 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
2176 * nsfont.m (ns_ascii_average_width): Ensure the string
2177 ascii_printable is initialized with a null-terminated character
2178 array. Otherwise, it can contain undesired extra characters.
2180 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2182 port new setting code to Sun C 5.8 2005/10/13
2183 * chartab.c, lisp.h (char_table_set, char_table_set_range):
2184 Return void, not Lisp_Object. Otherwise, the compiler
2185 complains about (A?B:C) where B is void and C is Lisp_Object
2186 when compiling CHAR_TABLE_SET, due to the recent change to
2187 the API of sub_char_table_set_contents.
2189 2012-08-18 Chong Yidong <cyd@gnu.org>
2191 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
2192 for the string case (Bug#3874).
2194 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2196 * buffer.h (BSET): Remove (Bug#12215).
2197 Replace all uses with calls to new setter functions.

2225 * category.c (bset_category_table):
2226 * syntax.c (bset_syntax_table):
2227 New setter functions.
2229 * process.h (PSET): Remove (Bug#12215).
2230 Replace all uses with calls to new setter functions.
2231 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
2232 (PROCESS_INLINE): New macro.
2233 (pset_childp): New setter function.
2234 (pset_gnutls_cred_type) [HAVE_GNUTLS]: New setter function.
2235 * process.c (PROCESS_INLINE):
2236 Define to EXTERN_INLINE, so that the corresponding functions
2237 are compiled into code.
2238 (pset_buffer, pset_command, pset_decode_coding_system)

2241 (pset_plist, pset_sentinel, pset_status, pset_tty_name)
2242 (pset_type, pset_write_queue): New setter functions.
2244 * window.h (WSET): Remove (Bug#12215).
2245 Replace all uses with calls to new setter functions.

3131 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
3132 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
3133 since it's used in non-static inline functions now.
3135 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

3162 (INLINE_HEADER_END): New macros.
3163 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

3185 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
3187 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
3188 This how ASET and AREF are supposed to work, and makes
3189 it easier to think about future improvements. See
3190 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
3191 * charset.h (set_charset_attr): New function.

3575 (key_event): use uChar.UnicodeChar only if
3576 w32_console_unicode_input is non-zero.
3578 * w32console.c: Include w32heap.h.
3579 <w32_console_unicode_input>: New global variable.

3603 * alloc.c (listn): Fix the order the arguments are consed onto the
3606 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
3607 enumeration constants, as PURE and HEAP are too general, and clash
3608 with other headers and sources, such as gmalloc.c and the
3609 MS-Windows system headers. All users changed.
3611 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3613 Revert last save_excursion_save and save_excursion_restore changes.
3614 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

3624 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
3626 Improve GDB symbol export (Bug#12036).
3627 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
3628 arms of an 'if', not using conditional expressions; otherwise GDB
3629 complains about the types in the unevaluated arm when the argument
3630 is an integer literal.
3631 (xgetint): Simplify expression.
3632 * alloc.c (gdb_make_enums_visible): New constant. This ports to
3633 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
3634 Zaretskii in <http://bugs.gnu.org/12036#13>.
3635 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
3636 needed now that we have gdb_make_enums_visible.
3637 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
3638 (enum enum_USE_LSB_TAG):
3639 New enum types, packaging up enums that need to be exported to GDB.
3641 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3643 Utility function to make a list from specified amount of objects.

3657 * xdisp.c (syms_of_xdisp): Likewise.
3658 * xfns.c (syms_of_xfns): Likewise.
3660 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3662 Fast save_excursion_save and save_excursion_restore.
3663 * lisp.h (struct Lisp_Excursion): New data type.
3664 (PVEC_EXCURSION): New pseudovector type.
3665 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
3666 to deal with it. Adjust comments.
3667 (init_marker, attach_marker): New prototype.
3668 (unchain_marker): Adjust prototype.

3677 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
3679 Fix export of symbols to GDB (Bug#12036).
3680 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
3681 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
3682 emacs.c, as this is a more-suitable home. Had this been done earlier
3683 the fix for 12036 would have avoided some of the problems noted in
3684 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
3685 would have been more obvious.
3686 * emacs.c: Do not include <verify.h>; no longer needed.
3687 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
3688 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
3689 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3690 Remove; now done in lisp.h.
3691 * lisp.h (PUBLISH_TO_GDB): New macro.
3692 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
3693 (DATA_SEG_BITS): Use it.
3694 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
3695 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3696 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3697 not be usable in #if. This simplifies things.
3699 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
3701 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
3703 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
3705 Simplify export of symbols to GDB (Bug#12036).
3706 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3707 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3708 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3709 Adjust to changes in lisp.h and emacs.c, by using
3710 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
3711 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
3712 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
3713 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
3714 instead of gdb_valbits.
3715 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
3716 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
3717 instead of gdb_array_mark_flag.
3718 (xboolvector): Get size from $->size, not $->header.size.
3719 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
3720 (xreload, hook-run, hookpost-run): Remove.
3721 * emacs.c: Include <verify.h>.
3722 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
3723 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
3725 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
3726 (gdb_USE_LSB_TAG): New enum constants.
3727 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3728 Also define these as enum constants, so they're visible to GDB.
3729 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
3730 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
3731 as constants, so they're visible to GDB.
3732 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
3733 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
3734 Now enum constants, not macros, so they're visible to GDB.
3735 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
3736 more convenient now. All uses changed.
3737 (VALMASK) [USE_LSB_TAG]: Also define in this case.
3738 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
3740 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

3745 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
3747 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
3748 add argument, tune behavior, and adjust all callers.
3750 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
3752 Use typedef for EMACS_INT, EMACS_UINT.
3753 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
3754 than macros. This simplifies debugging in the usual case, since
3755 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
3756 and it allows expressions involving EMACS_INT casts.
3757 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
3759 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
3761 * nsterm.m (ns_read_socket): Return early if there is a modal

3767 that FOCUS-FRAME can be omitted.
3769 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
3771 Adjust buffer text indirection counters at the end of Fkill_buffer.
3772 * buffer.c (Fkill_buffer): Adjust indirection counters when the
3773 buffer is definitely dead. This should really fix an issue reported
3774 by Christoph Scholtes again. (Bug#12007).
3775 (init_buffer_once): Initialize indirection counters of
3776 buffer_defaults and buffer_local_symbols (for sanity and safety).
3778 2012-07-24 Eli Zaretskii <eliz@gnu.org>
3780 * xdisp.c (init_iterator): Don't compute dimensions of truncation
3781 and continuation glyphs on tooltip frames, leave them at zero.
3782 Avoids continued lines in tooltips. (Bug#11832)
3784 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
3786 Simplify copy_overlay.
3787 * buffer.c (copy_overlay): Simplify. Use build_marker.

3796 it signals an error when a tooltip frame is being created.
3798 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3800 Cleanup miscellaneous objects allocation and initialization.

3809 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3811 Swap buffer text indirection counters in Fbuffer_swap_text.
3812 * buffer.c (Fbuffer_swap_text): Swap indirections too.
3813 This avoids crash reported by Christoph Scholtes at
3814 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
3816 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
3818 * nsmenu.m (Popdown_data): New struct.
3819 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
3821 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
3822 (initWithContentRect): Make imgView and contentView non-static
3823 and autorelease them. Also autorelease img and matrix (Bug#12005).
3824 (dealloc): Remove (Bug#12005).
3826 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
3828 Adjust consing_since_gc when objects are explicitly freed.

3841 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
3843 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
3844 as it's limited by the amount of memory, not by INT_MAX.
3846 2012-07-21 Eli Zaretskii <eliz@gnu.org>
3848 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
3849 in special-event-map. See the discussion at
3850 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
3853 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
3854 info.dwItemData. Fixes crashes on 64-bit Windows.

3908 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
3909 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
3910 Adjust users accordingly.
3911 * font.h (font_open_by_name): Adjust prototype.
3913 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

3929 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
3930 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
3931 'for_each_per_buffer_object_at'.
3932 All uses changed. It's better to use upper-case for macros that
3933 cannot be implemented as functions, to give the reader a clue
3934 that they're special.
3936 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
3938 * alloc.c (Fgarbage_collect): Tweak docstring.

3979 * intervals.c (merge_interval_right, merge_interval_left):
3980 Do not zero out this interval if it is absorbed by its children,
3981 as this interval's total length doesn't change in that case. See
3982 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
3984 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
3986 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
3987 when invoking (make-bool-vector N t) and N is a positive
3988 multiple of 8 -- the last 8 bits were mistakenly cleared.
3990 Remove some struct layout assumptions in bool vectors.
3991 * alloc.c (bool_header_size): New constant.
3992 (header_size, word_size): Move earlier, as they're now used earlier.

3994 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
3995 padding before the data member of a bool vector.
3996 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
3997 than doing the check by hand with an abort ().
3999 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
4001 * eval.c (Fdefvar): Don't check constants since we only set the var if
4002 it's not yet defined anyway (bug#11904).
4004 * lisp.h (last_undo_boundary): Declare new var.
4005 * keyboard.c (command_loop_1): Set it.
4006 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
4007 were auto-added by the command loop (bug#11774).
4009 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
4011 * w32font.c (Qsymbol): Remove local definition.

4500 2012-07-11 Glenn Morris <rgm@gnu.org>
4502 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
4503 since nothing has defined it on these platforms.
4505 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
4506 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

4517 2012-07-11 John Wiegley <johnw@newartisans.com>
4519 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
4520 function attribute, so we only use it if it exists in the
4523 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
4525 Avoid call to strlen in fast_c_string_match_ignore_case.

4572 * s/aix4-2.h (unix): Remove; no longer needed.
4574 EMACS_TIME simplification (Bug#11875).
4575 This replaces macros (which typically do not work in GDB)
4576 with functions, typedefs and enums, making the code easier to debug.
4577 The functional style also makes code easier to read and maintain.
4578 * systime.h: Include <sys/time.h> on all hosts, not just if
4579 WINDOWSNT, since 'struct timeval' is needed in general.
4580 (EMACS_TIME): Now a typedef, not a macro.
4581 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
4583 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

4587 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
4588 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
4589 which are not functions. All uses rewritten to use:
4590 (make_emacs_time): New function.
4591 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
4592 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4593 not functions. All uses rewritten to use the following, respectively:
4594 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
4595 (add_emacs_time, sub_emacs_time): New functions.
4596 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
4597 * fileio.c (Fcopy_file):
4598 * xterm.c (XTflash): Get the current time closer to when it's used.
4599 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

4607 * gtkutil.c (get_utf8_string):
4609 * nsmenu.m (ns_update_menubar):
4610 * regex.c (regerror):
4611 Prefer memcpy to strncpy and strncat when either will do.
4612 * fileio.c (Fsubstitute_in_file_name):
4613 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
4614 (menu_separator_name_p):
4615 * nsmenu.m (ns_update_menubar):
4616 Prefer memcmp to strncmp when either will do.
4617 * nsterm.m: Include <ftoastr.h>.
4619 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
4620 Prefer snprintf to strncpy.
4621 * nsterm.m (ns_term_init):
4622 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4623 * nsterm.m (ns_term_init):
4624 Avoid the need for strncpy, by using build_string or
4625 make_unibyte_string directly. Use dtoastr, not snprintf.
4626 * process.c (Fmake_network_process): Diagnose service names that
4627 are too long, rather than silently truncating them or creating
4628 non-null-terminated names.
4629 (Fnetwork_interface_info): Likewise, for interface names.
4630 * sysdep.c (system_process_attributes) [GNU_LINUX]:
4631 Prefer sprintf to strncat.
4632 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
4633 Prefer vsnprintf to vsprintf + strncpy.
4635 2012-07-10 Glenn Morris <rgm@gnu.org>
4637 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
4638 Clarify fallback case.
4640 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4642 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
4643 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
4644 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
4645 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
4646 where argument type is known to be a Lisp_Cons.
4648 2012-07-10 Tom Tromey <tromey@redhat.com>
4650 * bytecode.c (BYTE_CODE_THREADED): New macro.

4658 Optimize pure C strings initialization.
4659 * lisp.h (make_pure_string): Fix prototype.
4660 (build_pure_c_string): New function, defined as static inline. This
4661 provides a better opportunity to optimize away calls to strlen when
4662 the function is called with compile-time constant argument.
4663 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
4664 argument, adjust users accordingly. Use build_pure_c_string where
4666 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
4667 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
4668 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
4670 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4672 Avoid calls to strlen in miscellaneous functions.
4673 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
4674 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
4675 * lread.c (openp): Likewise.
4677 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4679 Avoid calls to strlen in path processing functions.
4680 * fileio.c (file_name_as_directory): Add comment. Change to add
4681 srclen argument and return the length of result. Adjust users
4683 (directory_file_name): Fix comment. Change to add srclen argument,
4684 swap 1st and 2nd arguments to obey the common convention.
4685 Adjust users accordingly.
4686 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
4688 2012-07-10 Glenn Morris <rgm@gnu.org>
4690 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

4693 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
4694 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
4695 * s/gnu.h (DATA_START): Move definitions to configure.
4697 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
4698 We include usg5-4-common.h, which defines them both.
4700 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
4701 O_RDONLY already includes it).
4703 Stop ns builds setting the EMACSLOADPATH environment variable.
4704 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4705 Now it does not set EMACSLOADPATH, just returns the load-path string.
4706 * nsterm.h: Update accordingly.
4707 * lread.c [HAVE_NS]: Include nsterm.h.
4708 (init_lread) [HAVE_NS]: Use ns_load_path.
4709 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
4711 2012-07-09 Glenn Morris <rgm@gnu.org>
4713 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
4714 since the included bsd-common.h does so.
4716 Stop ns builds setting the EMACSPATH environment variable.
4717 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
4718 (ns_init_paths): Do not set EMACSPATH.
4719 * nsterm.h (ns_exec_path): Add it.
4720 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
4723 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
4725 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
4727 * process.c (wait_reading_process_output): 'waitchannels' was unset
4728 when read_kbd || !NILP (wait_for_cell); fix this.
4730 Add GCC-style 'const' attribute to functions that can use it.
4731 * character.h (char_resolve_modifier_mask):
4732 * keyboard.h (make_ctrl_char):
4733 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
4734 (init_character_once, next_almost_prime, init_fns, init_image)
4735 (flush_pending_output, init_sound):
4736 * mem-limits.h (start_of_data):

4740 Declare the dummy function with ATTRIBUTE_CONST.
4741 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
4742 Add decls with ATTRIBUTE_CONST.
4744 Minor improvements to make_formatted_string.
4745 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
4746 where int is good enough, as vsprintf returns an int.
4747 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
4749 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4751 Use make_formatted_string to avoid double length calculation.
4752 * lisp.h (make_formatted_string): New prototype.
4753 * alloc.c (make_formatted_string): New function.
4754 * buffer.c (Fgenerate_new_buffer_name): Use it.
4755 * dbus.c (syms_of_dbusbind): Likewise.
4756 * editfns.c (Fcurrent_time_zone): Likewise.
4757 * filelock.c (get_boot_time): Likewise.
4758 * frame.c (make_terminal_frame, set_term_frame_name)
4759 (x_report_frame_params): Likewise.
4760 * image.c (gs_load): Likewise.
4761 * minibuf.c (get_minibuffer): Likewise.
4762 * msdos.c (dos_set_window_size): Likewise.
4763 * process.c (make_process): Likewise.

4776 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4778 Move marker debugging code under MARKER_DEBUG.
4779 * marker.c (MARKER_DEBUG): Move marker debugging code under
4780 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4781 for bootstrap with --enable-checking (~3x slowdown reported
4782 by Juanma Barranquero <lekktu@gmail.com>).
4783 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4785 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4787 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
4788 See <http://bugs.gnu.org/11825#29>.
4790 2012-07-08 Eli Zaretskii <eliz@gnu.org>
4792 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4793 has no font, use the frame's font. (Bug#11813)
4794 (display_line): Add commentary about displaying truncation glyphs
4796 (produce_special_glyphs): Move here from term.c.
4798 * term.c (produce_special_glyphs): Move to xdisp.c.
4800 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4803 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4805 * xdisp.c (display_line): Avoid warning about implicit declaration
4808 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4810 * lisp.h: Remove empty conditional.
4812 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4814 * lread.c (load_path_check): Now static.
4816 Fix some minor --with-ns problems found by static checking.
4817 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
4818 (x_set_font) [!HAVE_X_WINDOWS]:
4819 * image.c (xpm_load_image) [HAVE_NS]:
4820 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4821 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4822 Remove unused local.
4823 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
4824 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
4825 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
4826 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
4827 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
4828 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
4829 Fix pointer signedness problem.
4830 * xfaces.c (FRAME_X_FONT_TABLE):
4831 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
4833 2012-07-07 Glenn Morris <rgm@gnu.org>
4835 * lread.c (load_path_check): New function, split from init_lread.
4836 (init_lread): Reorganize. Motivation:
4837 If EMACSLOADPATH is set, check/warn about that rather than the
4838 defaults, which we are not going to use. Hence we can remove
4839 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4840 Don't warn if site-lisp directories are missing.
4841 If not installed, start from a blank load-path, since
4842 PATH_LOADSEARCH refers to the eventual installation directories.
4844 2012-07-07 Eli Zaretskii <eliz@gnu.org>
4846 Support truncation and continuation glyphs on GUI frames, when
4847 fringes are disabled. (Bug#11832)
4848 * xdisp.c (init_iterator): Get dimensions of truncation and
4849 continuation glyphs even if on GUI frames.
4850 Adjust it->last_visible_x on GUI frames when the left or right fringes,
4851 or both, are absent.
4852 (start_display, move_it_in_display_line_to): Handle the case of a
4853 GUI frame without a fringe to display continuation or truncation
4855 (insert_left_trunc_glyphs): Support GUI frames: make sure
4856 truncation glyphs overwrite enough glyphs from the current line to
4857 have sufficient space in pixels.
4858 (display_line): Support truncation and continuation glyphs on GUI
4859 frames. If some spare pixels are left on the line after inserting
4860 the truncation glyphs, fill that space with a stretch glyph of a
4861 suitably computed width.
4863 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4864 produce_glyphs, to support GUI sessions.
4866 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4868 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4870 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4872 Do not require float-time's arg to fit in time_t (Bug#11825).
4873 This works better on hosts where time_t is unsigned, and where
4874 float-time is applied to the (negative) difference between two times.
4875 * editfns.c (decode_time_components): Last arg is now double *,
4876 not int *, and means to store all the result as a double, without
4877 worrying about whether the seconds part fits in time_t.
4878 All callers changed.
4879 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4880 All callers changed.
4881 (Ffloat_time): Do not fail merely because the specified time falls
4882 outside of time_t range.
4884 2012-07-07 Glenn Morris <rgm@gnu.org>
4886 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
4887 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
4888 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
4890 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
4892 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
4893 Update dependencies.
4895 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
4897 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4899 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
4900 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
4901 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
4902 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
4903 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
4904 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
4906 * xfont.c (compare_font_names): Redo to omit the need for casts.
4908 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4910 * xfns.c (Fx_change_window_property): Doc fix.
4911 * w32fns.c (Fx_change_window_property): Doc fix.
4913 * w32fns.c (Fx_window_property): Accept the same arguments as the
4914 X Windows version. Doc fix.
4915 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4917 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4918 Eli Zaretskii <eliz@gnu.org>
4920 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4921 Windows-specific code from nt/config.nt moved here.
4922 Obsolete settings removed.
4924 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4926 * process.c: Avoid unnecessary calls to gettime.
4927 (wait_reading_process_output): Don't get the time of day
4928 when gobbling data immediately and not waiting, as there's no need
4929 for it in that case. This removes a FIXME.
4931 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4933 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4934 is defined (Bug#11768).
4936 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4938 Fix marker debugging code.
4939 * marker.c (byte_char_debug_check): Do not perform the check
4940 if buffer is not multibyte.
4941 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4942 Call byte_char_debug_check with correct arguments.
4944 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4946 Compile marker debugging code only if ENABLE_CHECKING is defined.
4947 * marker.c (byte_char_debug_check, count_markers):
4948 Use only if ENABLE_CHECKING is defined.
4949 (byte_debug_flag): Remove.
4950 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4951 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4953 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4955 Avoid code repetition in marker-related functions.
4956 * marker.c (attach_marker): New function.

4958 (set_marker_restricted_both): Use it.
4959 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4960 Consistently rename charno to charpos.
4961 (marker_position): Add eassert.
4962 (marker_byte_position): Convert to eassert.
4964 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4966 Simplify list operations in unchain_overlay and unchain_marker.

4974 * lisp.h (build_marker): New prototype.
4975 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
4976 * composite.c (autocmp_chars): Likewise.
4977 * editfns.c (buildmark): Remove.
4978 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
4979 (save_restriction_save): Use build_marker.
4980 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
4981 * window.c (save_window_save): Likewise.
4983 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

4986 to avoid redundant calls to unchain_overlay.
4987 * buffer.c (drop_overlay): New function.
4988 (delete_all_overlays, Fdelete_overlay): Use it.
4989 * minibuf.c (get_minibuffer): Fix comment.
4991 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4993 Port to OpenBSD 5.1 amd64.
4994 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4995 This is needed for OpenBSD, and should be harmless on all BSD systems.
4996 Also, include <sys/sysctl.h>, as it should be available on all
4997 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4998 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4999 use p_pid member, not kp_proc.pid.
5001 2012-07-06 Glenn Morris <rgm@gnu.org>
5003 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
5005 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5007 More xmalloc and related cleanup.
5008 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

5016 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
5018 Omit needless casts involving void * pointers and allocation.
5019 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
5020 as the former is more robust if P's type is changed.
5021 Prefer xzalloc to xmalloc + memset 0.
5022 Simplify malloc-or-realloc to realloc.
5023 Don't worry about xmalloc returning a null pointer.
5024 Prefer xstrdup to xmalloc + strcpy.
5025 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
5027 * keyboard.c (apply_modifiers_uncached): Prefer local array to
5028 alloca of a constant.
5030 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5032 * xdisp.c (display_line): Fix horizontal pixel coordinates when
5033 hscroll is larger than the line width. Fixes long and futile
5034 looping inside extend_face_to_end_of_line (on a TTY) producing
5035 glyphs that are not needed and thrown away.
5037 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5039 * marker.c (set_marker_restricted_both): Simplify by using
5042 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5044 * editfns.c (region_limit): Simplify by using clip_to_bounds.

5049 not defined (Bug#11768).
5050 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
5051 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
5052 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
5053 followed by gtk_box_set_homogeneous (Bug#11768).
5054 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
5055 (update_theme_scrollbar_width, xg_create_scroll_bar):
5056 Use gtk_scrollbar_new (Bug#11768).
5057 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
5058 (is_box_type): New function (Bug#11768).
5059 (xg_tool_item_stale_p): Call is_box_type.
5060 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
5061 with default display (Bug#11768).

5065 * xdisp.c (window_hscroll_limited): New function.
5066 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
5067 coordinates when window's hscroll is set to insanely large
5070 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
5072 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

5131 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5133 * fileio.c (time_error_value): Check the right error number.
5134 Problem reported by Troels Nielsen in
5135 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
5137 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5139 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
5140 This should be fixed in a better way; see Eli Zaretskii in
5141 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
5142 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
5144 * fileio.c (time_error_value): Rename from special_mtime.
5145 The old name's problems were noted by Eli Zaretskii in
5146 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
5148 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
5149 This variable's comment says Emacs needs at least one GDB-visible
5150 symbol of type enum pvec_type, to work around GDB problems.
5151 The symbol's value doesn't matter.
5153 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
5154 that causes compilation to fail on pre-C99 compilers.
5156 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
5158 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
5159 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
5161 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5163 * buffer.c (init_buffer_once): Fix initialization of
5164 headers for buffer_defaults and buffer_local_symbols.
5165 Reported by Juanma Barranquero <lekktu@gmail.com>.
5167 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
5169 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
5170 * lisp.h (enum pvec_type): Use fewer bits.
5171 (PSEUDOVECTOR_SIZE_BITS): New constant.
5172 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
5173 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
5174 change in pvec_type.
5175 (PSEUDOVECTOR_TYPEP): New macro.
5176 (TYPED_PSEUDOVECTORP): Use it.

5181 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
5182 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
5183 (sweep_vectors): Use it. Use local var `total_bytes' instead of
5184 abusing vector->header.next.nbytes.
5185 (live_vector_p): Use PVEC_TYPE.
5186 (mark_object): Adapt code to extract pvectype. Use switch.
5188 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5190 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
5191 Tighten new eassert a bit.
5193 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5195 Fix compilation with --enable-gcc-warnings and -O1
5197 * doprnt.c (doprnt): Change type of tem to int, initialize
5198 to avoid compiler warning. Add eassert.
5199 * search.c (simple_search): Initialize match_byte to avoid
5200 compiler warning. Add eassert.
5202 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5204 Avoid weird behavior with large horizontal scrolls.
5205 Without this change, for example, large hscroll values would
5206 mess up Emacs's display on Fedora 15 x86, presumably due to
5207 overflows in int calculations in the display code.
5208 Also, if buffers had long lines, Emacs would freeze.
5209 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
5210 (set_window_hscroll): New function, containing the old guts of
5211 Fset_window_hscroll. Return the clipped value.
5212 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
5213 This avoids the need to check against PTRDIFF_MAX.
5215 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
5217 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5219 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
5221 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5223 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
5224 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
5225 since GCC 4.4.6 issues a bogus warning for them.
5227 Fix bugs in file timestamp newness comparisons.
5228 * fileio.c (Ffile_newer_than_file_p):
5229 * lread.c (Fload): Use full timestamp resolution of files,
5230 not just the 1-second resolution, so that files that are only
5231 slightly newer still count as newer.
5232 * fileio.c (Ffile_newer_than_file_p): Don't assume file
5233 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
5235 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
5237 * fileio.c: Improve handling of file time marker. (Bug#11852)
5238 (special_mtime): New function.
5239 (Finsert_file_contents, Fverify_visited_file_modtime):
5240 Use it to set special mtime values consistently.
5242 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
5244 * fileio.c (Finsert_file_contents): Properly handle st_mtime
5245 marker for non-existing file. (Bug#11852)
5247 2012-07-03 Glenn Morris <rgm@gnu.org>
5249 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
5250 and did not make it into globals.h).
5252 2012-07-03 Tom Tromey <tromey@redhat.com>
5254 * window.c (Fset_window_margins, Fset_window_fringes)

5288 * xterm.h: Remove EXFUN.
5290 2012-07-03 Glenn Morris <rgm@gnu.org>
5292 * lisp.h (Frandom): Make it visible to C.
5293 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
5294 buffer for invisible buffers. (Bug#1229)

5298 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
5299 values which aren't power of 2.
5300 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
5301 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
5304 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
5306 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

5310 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5312 * alloc.c (allocate_vector_block): Remove redundant
5313 calls to mallopt if DOUG_LEA_MALLOC is defined.
5314 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
5315 avoid calls to mallopt if zero_vector is returned.
5317 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5319 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
5320 is enabled, avoid dereferencing NULL current_sblock if
5323 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5325 Cleanup basic buffer management.
5326 * buffer.h (struct buffer): Change layout to use generic vector
5327 marking code. Fix some comments. Change type of 'clip_changed'
5328 to bitfield. Remove unused #ifndef old.
5329 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
5330 (GET_OVERLAYS_AT): Fix indentation.
5331 (for_each_per_buffer_object_at): New macro.

5335 * alloc.c (allocate_buffer): Adjust to match new layout of
5336 struct buffer. Fix comment.
5337 (mark_overlay): New function.
5338 (mark_buffer): Use it. Use mark_vectorlike to mark normal
5339 Lisp area of struct buffer.
5340 (mark_object): Use it. Adjust marking of misc objects
5341 and related comments.
5343 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
5345 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
5346 wrapper that is not needed because the wrapped code is a no-op (zero
5347 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
5348 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
5350 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
5352 * alloc.c (mark_buffer): Simplify. Remove prototype.
5353 (mark_object): Add comment. Reorganize marking of vector-like
5354 objects. Use CHECK_LIVE for all vector-like objects except buffers
5355 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
5356 Avoid redundant calls to mark_vectorlike for bool vectors.
5358 2012-06-30 Glenn Morris <rgm@gnu.org>
5360 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
5362 * epaths.in (PATH_SITELOADSEARCH): New.
5363 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
5364 This is rather than relying on --enable-locallisppath elements
5365 having "site-lisp" in their names. (Bug#10208#25, 11658)
5367 2012-06-30 Eli Zaretskii <eliz@gnu.org>
5369 * w32proc.c (sys_select): Accept and ignore one more argument.
5371 * w32.c (emacs_gnutls_pull): Call select with one more argument.
5373 * sysselect.h [DOS_NT]: Don't include sys/select.h.
5374 (pselect) [!MS_DOS]: Redirect to sys_select.
5376 * sysdep.c: Don't include dos.h and dosfns.h.
5378 * process.c (sys_select):
5379 * msdos.c (sys_select): Accept one more argument and ignore it.
5381 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
5382 adapt data types and code to that.
5385 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
5386 which clashes with the gnulib function of the same name.
5388 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
5390 * font.c (font_style_to_value, font_style_symbolic)
5391 (font_prop_validate_style): Add type checks for values in
5394 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
5396 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
5399 2012-06-29 Eli Zaretskii <eliz@gnu.org>
5401 * xdisp.c (try_window_id): Undo last change.
5403 * w32.c (getwd): Adjust commentary about startup_dir.
5404 (init_environment): Always call sys_access, even in non-MSVC
5405 builds. Don't chdir to the directory of the Emacs executable.
5406 This undoes code from 1997 which was justified by the need to
5407 "avoid conflicts when removing and renaming directories". But its
5408 downside was that every relative file name was being interpreted
5409 relative to the directory of the Emacs executable, which can never
5410 be TRT. In particular, it broke sys_access when called with
5411 relative file names.
5412 (sys_access): Map GetLastError to errno.
5414 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5416 * window.h (struct window): Change type of 'fringes_outside_margins'

5461 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
5462 from EMACS_INT to ptrdiff_t.

5538 * alloc.c (allocate_string): Omit intervals initialization.
5539 * alloc.c (make_uninit_multibyte_string): Initialize intervals

5596 * alloc.c: Remove build_string.
5597 * lisp.h: Define build_string as static inline. This provides
5598 a better opportunity to optimize away calls to strlen when the
5599 function is called with compile-time constant argument.
5600 * image.c (imagemagick_error): Convert to build_string.
5601 * w32proc.c (sys_spawnve): Likewise.

5604 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
5606 Use sprintf return value instead of invoking strlen on result.
5607 In the old days this wasn't portable, since some sprintf
5608 implementations returned char *. But they died out years ago and
5609 Emacs already assumes sprintf returns int.
5610 Similarly for float_to_string.
5611 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

5618 * xfns.c (syms_of_xfns):
5619 Use sprintf or float_to_string result to avoid need to call strlen.
5620 * data.c (Fnumber_to_string):
5621 Use make_unibyte_string, since the string must be ASCII.
5622 * lisp.h, print.c (float_to_string): Now returns int length.
5623 * term.c (produce_glyphless_glyph):
5624 Use sprintf result rather than recomputing it.
5626 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
5627 * Makefile.in (ALL_CFLAGS):
5628 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

5634 strcasecmp if available.

5653 sprintf already null-terminates its output.
5655 * xfns.c (x_window): Remove redundant cast.
5657 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
5659 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
5660 `const char *' to `char *' to avoid compiler warning.
5662 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
5664 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
5665 instead of truncating it to 63 (admittedly a generous limit).
5667 * process.c: Fix spelling and caps in comments.
5669 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

5724 * dispnew.c (Fsleep_for, sit_for):
5725 * keyboard.c (kbd_buffer_get_event):
5726 * process.c (Faccept_process_output):
5727 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
5728 This improves on the previous patch, which introduced a bug
5729 when time_t is unsigned and as wide as intmax_t.
5730 See <http://bugs.gnu.org/9000#51>.
5732 2012-06-23 Eli Zaretskii <eliz@gnu.org>

5748 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
5749 Privately reported by Herbert J. Skuhra.
5750 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

5761 language ID in the event parameters.
5763 * w32term.c (w32_read_socket): Put the new keyboard codepage into

5795 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5797 Support higher-resolution time stamps (Bug#9000).
5798 The time stamps are only nanosecond-resolution at the C level,
5799 since that's the best that any real-world system supports now.
5800 But they are picosecond-resolution at the Lisp level, as that's
5801 easy, and leaves room for future OS improvements.
5803 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5806 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5807 Don't get current time unless it's needed.
5809 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5810 now provides it if it's absent.
5811 (start_atimer): Port to higher-res time stamps.
5812 Check for time stamp overflow. Don't get current time more
5813 often than is needed.
5815 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5816 Include systime.h, not time.h.
5817 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
5819 * dired.c: Include stat-time.h.
5820 (Ffile-attributes): File times now have higher resolution.
5822 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
5823 (struct image): Timestamp now has higher resolution.
5825 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5826 has at least microseconds now. All uses removed.
5827 (update_frame, update_single_window, update_window, update_frame_1)
5828 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5829 (duration_to_sec_usec): Remove; no longer needed.
5831 * editfns.c (time_overflow): Now extern.
5832 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
5833 (float-time, Fformat_time_string, Fcurrent_time_string)
5834 (Fcurrent_time_zone): Accept and generate higher-resolution
5836 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
5837 (decode_time_components, lisp_seconds_argument): New functions.
5838 (make_time): Now static.
5839 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
5840 Report an error if the time is invalid, rather than having the caller
5843 * fileio.c: Include <stat-time.h>
5844 (Fcopy_file): Copy higher-resolution time stamps.
5845 Prefer to set the time stamp via a file descriptor if that works.
5846 (Fset_file_times, Finsert_file_contents, Fwrite_region)
5847 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
5848 (Fvisited_file_modtime, Fset_visited_file_modtime):
5849 Support higher-resolution time stamps.
5851 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
5853 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
5855 * image.c (prepare_image_for_display, clear_image_cache)
5856 (lookup_image): Port to higer-resolution time stamps.
5858 * keyboard.c (start_polling, bind_polling_period):
5859 Check for time stamp overflow.
5860 (read_char, kbd_buffer_get_event, timer_start_idle)
5861 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
5862 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5863 Port to higher-resolution time stamps. Do not assume time_t is signed.
5864 (decode_timer): New function. Timers are now vectors of length 9,
5865 not 8, to accommodate the picosecond component.
5866 (timer_check_2): Use it.
5868 * nsterm.m (select_timeout, timeval_subtract): Remove.
5869 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5870 as they're a bit more accurate and handle overflow better.
5871 (ns_select): Change prototype to be compatible with pselect.
5872 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5873 * nsterm.h (ns_select): Adjust prototype.
5875 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5876 us-resolution time stamps.
5877 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5879 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5881 * lisp.h (time_overflow): New decl.
5882 (wait_reading_process_output): First arg is now intmax_t, not int,
5883 to accommodate larger waits.
5885 * process.h (struct Lisp_Process.read_output_delay):
5886 Now counts nanoseconds, not microseconds.
5887 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
5889 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
5890 (wait_reading_process_output):
5891 Port to ns-resolution time stamps.
5892 (Faccept_process_output, wait_reading_process_output):
5893 Check for time stamp overflow. Do not assume time_t is signed.
5894 (select_wrapper): Remove; we now use pselect.
5895 (Fprocess_attributes): Now generates ns-resolution time stamps.
5897 * sysdep.c: Include utimens.h. Don't include utime.h
5898 or worry about struct utimbuf; gnulib does that for us now.
5899 (gettimeofday): Remove; gnulib provides a substitute.
5900 (make_timeval): New function.
5901 (set_file_times): Now sets ns-resolution time stamps.
5902 New arg FD; all uses changed.

5905 Now returns ns-resolution time stamp. All uses changed.
5906 Check for time stamp overflow.
5908 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5909 provides a substitute now.
5911 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5912 since it guarantees struct timespec.
5913 (EMACS_TIME): Now struct timespec, so that we can support
5914 ns-resolution time stamps.
5915 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.

5917 (EMACS_USECS): Remove.
5918 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5919 so multiply the arg by 1000 before storing it.
5920 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
5922 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

5929 (make_timeval, make_lisp_time, decode_time_components): New decls.
5930 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
5931 that it mishandled time_t overflow. You can't compare by subtracting!
5932 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
5933 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
5935 * term.c: Include <sys/time.h>.
5936 (timeval_to_Time): New function, for proper overflow wraparound.

5939 * undo.c (record_first_change): Support higher-resolution time stamps
5941 (Fprimitive_undo): Use them when restoring time stamps.
5943 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
5944 (w32_get_internal_run_time):
5945 Port to higher-resolution Emacs time stamps.
5946 (ltime): Now accepts single 64-bit integer, as that's more convenient
5949 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
5951 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
5952 for compatibility with pselect. Support ns-resolution time stamps.

5956 * xselect.c (wait_for_property_change, x_get_foreign_selection):
5957 Check for time stamp overflow, and support ns-resolution time stamps.
5959 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
5960 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
5961 (timeval_subtract): Remove; no longer needed.
5962 (XTflash, XTring_bell, x_wait_for_event):
5963 Port to ns-resolution time stamps. Don't assume time_t is signed.

5969 2012-06-22 Eli Zaretskii <eliz@gnu.org>
5971 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
5972 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5973 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
5974 staticidx goes up to 1597 out of 1600 = 0x640.)
5976 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
5978 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
5979 Otherwise, the umask might be mistakenly 0 while handling input signals.
5981 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
5983 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

5989 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
5990 access to `contents' member of Lisp_Vector objects with AREF and ASET
5993 2012-06-19 Chong Yidong <cyd@gnu.org>
5995 * frame.c (delete_frame): When selecting a frame on a different
5996 text terminal, do not alter the terminal's top-frame.

6000 (unwind_format_mode_line): Restore them.
6001 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
6003 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
6004 since tty frames can be explicitly named.
6005 (prepare_menu_bars): Likewise.
6007 * term.c (Ftty_top_frame): New function.
6009 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
6011 Port byte-code-meter to modern targets.
6012 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
6013 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
6014 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
6015 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
6016 (METER_1, METER_2): Simplify.

6022 2012-06-18 Martin Rudalics <rudalics@gmx.at>
6024 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
6025 gets killed during executing of this function (Bug#11665).
6026 Try to always return Qt when the buffer has been actually killed.
6027 (Vkill_buffer_query_functions): In doc-string say that functions
6028 run by this hook should not change the current buffer.
6030 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
6032 Fix recently-introduced process.c problems found by static checking.
6033 * process.c (write_queue_push, write_queue_pop, send_process):

6052 * lisp.h (eassert): Assume C89 or later.
6053 This removes the need for CHECK.
6054 (CHECK): Remove. Its comments about always evaluating its
6055 argument were confusing, as 'eassert' typically does not evaluate
6058 * coding.c (produce_chars): Use ptrdiff_t, not int.
6060 * xterm.c (x_draw_underwave): Check for integer overflow.
6061 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

6354 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
6356 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
6357 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
6359 2012-06-08 Eli Zaretskii <eliz@gnu.org>
6361 * alloc.c (allocate_vectorlike): Fix last change.
6363 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
6365 Block-based vector allocation of small vectors.
6366 * lisp.h (struct vectorlike_header): New field `nbytes',
6367 adjust comment accordingly.
6368 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
6369 to denote vector blocks. Adjust users (live_vector_p,
6370 mark_maybe_pointer, valid_lisp_object_p) accordingly.
6371 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
6372 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
6373 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
6374 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
6375 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.
6376 (roundup_size): New constant.

6390 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
6392 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
6394 * doprnt.c (doprnt): Truncate multibyte char correctly.
6395 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
6396 would mishandle a string argument "Xc" if X was a multibyte
6397 character of length 2: it would truncate after X's first byte
6398 rather than including all of X.
6400 2012-06-06 Chong Yidong <cyd@gnu.org>
6402 * buffer.c (word_wrap): Doc fix.

6428 (note_mode_line_or_margin_highlight): If there is no help echo,
6429 use mode-line-default-help-echo. Handle the case where the mouse
6430 position is past the end of the mode line string.

6449 * minibuf.c (Fassoc_string): Remove duplicate declaration.
6451 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
6452 Convert pctcpu and pctmem to Lisp float properly.
6453 Let the compiler fold better, as 100.0/0x8000 is exact.
6455 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
6457 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
6460 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
6462 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
6464 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
6466 For a 'struct window', replace some Lisp_Object fields to
6467 bitfields where appropriate, remove unused fields.
6468 * window.h (struct window): Remove unused 'last_mark_x' and
6469 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
6470 change it's type from Lisp_Object to bitfield.
6471 Change type of 'force_start', 'optional_new_start',
6472 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
6473 fields from Lisp_Object to bitfield. Adjust users accordingly.
6475 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6477 Pacify gcc -Wdouble-precision when using Xaw.
6478 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
6479 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
6480 Use 'float' consistently, rather than 'float' in most places
6481 and 'double' in a couple of places.
6483 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6485 * xdisp.c (handle_stop): Detect whether we have overlay strings
6486 loaded by testing it->current.overlay_string_index to be
6487 non-negative, instead of checking whether n_overlay_strings is
6488 positive. (Bug#11587)
6490 2012-05-31 Chong Yidong <cyd@gnu.org>
6492 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
6494 * doc.c (Fsubstitute_command_keys): Doc fix.
6496 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6498 * search.c (search_buffer): Remove calls to
6499 r_alloc_inhibit_buffer_relocation, as it is now called by
6500 maybe_unify_char, which was the cause of relocation of buffer text
6503 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6505 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6506 for the duration of call to load_charset, to avoid problems with
6507 callers of maybe_unify_char that access buffer text through C
6510 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6511 decrement the inhibition flag, instead of just setting or
6514 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6516 Remove obsolete '#define static' cruft.
6517 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6518 This #undef was "temporary" in 2000; it is no longer needed
6519 now that '#define static' has gone away.
6520 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6521 (gray_bitmap_bits): Remove; no longer needed.
6522 All uses replaced with definiens.
6523 * xterm.c: Include "bitmaps/gray.xbm".
6525 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6527 Clean up __executable_start, monstartup when --enable-profiling.
6528 The following changes affect the code only when profiling.
6529 * dispnew.c (__executable_start): Rename from safe_bcopy.
6530 Define only on platforms that need it.
6531 * emacs.c: Include <sys/gmon.h> when profiling.
6532 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6533 (__executable_start): Remove decl, since lisp.h does it now.
6534 (safe_bcopy): Remove decl; no longer has that name.
6535 (main): Coalesce #if into single bit of code, for simplicity.
6536 Cast pointers to uintptr_t, since standard libraries want integers

6561 * lread.c (read1): Tiny simplification.
6563 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
6565 Do not create empty overlays with the evaporate property (Bug#9642).
6566 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6567 Bug#9642, but explicitly check that the buffer the overlay would
6568 be moved to is live and rearrange lines to make sure that errors
6569 will not put the overlay in an inconsistent state.
6570 (Fdelete_overlay): Cosmetics.
6572 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6574 * w32term.c (my_bring_window_to_top): New function.
6575 (x_raise_frame): Use handle returned by DeferWindowPos, which
6576 could be different from the original one.

6580 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6581 by calling BringWindowToTop.
6583 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6584 (WM_EMACS_END): Increase by one.
6586 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6588 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6589 This avoids undefined behavior that might cause the eassert
6590 to not catch an out-of-range value.
6592 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6594 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

6604 when referring to sectname field in printf format.
6606 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
6608 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6609 Only r_alloc_inhibit_buffer_relocation needed to be added;
6610 the others were already declared.
6612 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6613 before checking whether it's out of range. Put the check inside
6615 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6617 2012-05-27 Ken Brown <kbrown@cornell.edu>
6619 * callproc.c (Fcall_process): Restore a line that was accidentally
6620 commented out in the 2011-02-13 change (bug#11547).

6624 * lisp.h [REL_ALLOC]: Add prototypes for external functions
6625 defined on ralloc.c.
6627 * buffer.c [REL_ALLOC]: Remove prototypes of
6628 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
6629 they are now on lisp.h.
6631 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6633 * search.c (search_buffer): Use it to inhibit relocation of buffer
6634 text while re_search_2 is doing its job, because re_search_2 is
6635 passed C pointers to buffer text. (Bug#11519)
6637 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6640 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6641 state after an additional call to move_it_in_display_line_to, keep
6642 the values of it->max_ascent and it->max_descent found for the
6644 (pos_visible_p): Revert the comparison against bottom_y to what it
6645 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
6648 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6650 Fix coding-related core dumps with gcc -ftrapv.
6651 The code was computing A - B, where A and B are pointers, and B is
6652 random garbage. This can lead to core dumps on platforms that
6653 have special pointer registers, and it also leads to core dumps on
6654 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6655 A - B only when B is initialized properly.
6656 * coding.c (coding_set_source, coding_set_destination): Return void.
6657 (coding_change_source, coding_change_destinations): New functions,
6658 with the old behaviors of coding_set_source and coding_set_destination.
6659 All callers that need an offset changed to use these new functions.
6661 2012-05-26 Glenn Morris <rgm@gnu.org>
6663 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
6665 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6667 Extend mouse support on W32 text-mode console.
6668 * xdisp.c (draw_row_with_mouse_face):
6669 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6671 * w32console.c: Include window.h.
6672 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6674 (initialize_w32_display): Initialize mouse-highlight data.
6676 * w32inevt.c: Include termchar.h and window.h.
6677 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6678 moves, call note_mouse_highlight. If help_echo changed, call
6679 gen_help_event to produce help-echo message in the echo area.
6680 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6683 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6685 * lread.c (read1): Simplify slightly to avoid an overflow warning
6686 with GCC 4.7.0 on x86-64.
6688 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6690 * bidi.c (bidi_mirror_char): Revert last change: an int is
6691 definitely wide enough here.
6693 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
6695 Fix integer width and related bugs (Bug#9874).

6705 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6706 (allocate_pseudovector):
6707 Use int, not EMACS_INT, where int is wide enough.
6708 (inhibit_garbage_collection, Fgarbage_collect):
6709 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6710 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
6711 int might not be wide enough.
6712 (bidi_cache_search, bidi_cache_find, bidi_init_it)

6715 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
6716 (bidi_level_of_next_char, bidi_move_to_visually_next):
6717 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6718 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
6719 (Fkill_buffer, Fset_buffer_major_mode)
6720 (advance_to_char_boundary, Fbuffer_swap_text)
6721 (Fset_buffer_multibyte, overlays_at, overlays_in)
6722 (overlay_touches_p, struct sortvec, record_overlay_string)
6723 (overlay_strings, recenter_overlay_lists)
6724 (adjust_overlays_for_insert, adjust_overlays_for_delete)
6725 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
6726 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
6727 (Foverlay_recenter, last_overlay_modification_hooks_used)
6728 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6729 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6730 (validate_region): Omit unnecessary test for b <= e,
6731 since that's guaranteed by the previous test.
6732 (adjust_overlays_for_delete): Avoid pos + length overflow.
6733 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6734 (report_overlay_modification):
6735 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6736 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
6737 Omit pointer cast, which isn't needed anyway, and doesn't work
6738 after the EMACS_INT -> ptrdiff_t change.
6739 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
6740 * buffer.h: Adjust decls to match defn changes elsewhere.
6741 (struct buffer_text, struct buffer):
6742 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6743 Use EMACS_INT, not int, where int might not be wide enough.
6744 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
6745 not int, to avoid needless 32-bit limit on 64-bit hosts.
6746 (exec_byte_code): Use tighter memory-full test, one that checks
6747 for alloca overflow. Don't compute the address of the object just
6748 before an array, as that's not portable. Use EMACS_INT, not
6749 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
6750 * callint.c (Fcall_interactively):
6751 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6752 * callproc.c (call_process_kill, Fcall_process):
6753 Don't assume pid_t fits into an Emacs fixnum.
6754 (call_process_cleanup, Fcall_process, child_setup):
6755 Don't assume pid_t fits into int.
6756 (call_process_cleanup, Fcall_process, delete_temp_file)

6761 * casefiddle.c (casify_object, casify_region, operate_on_word)
6762 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
6763 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6764 (casify_object): Avoid integer overflow when overallocating buffer.
6765 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
6766 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
6767 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
6768 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6769 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6770 integers are now checked earlier. All uses replaced with XINT.
6772 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6773 For CCL_MapSingle, check that content and value are in int range.

6775 Check that Vcode_version_map_vector is a vector.
6776 (resolve_symbol_ccl_program): Check that vector header is in range.
6777 Always copy the vector, so that we can check its contents reliably
6778 now rather than having to recheck each instruction as it's being
6779 executed. Check that vector words fit in 'int'.
6780 (ccl_get_compiled_code, Fregister_ccl_program)
6781 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6782 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
6783 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
6784 contents are in range.
6785 (Fccl_execute_on_string): Check that status is in range.
6786 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
6787 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
6788 Accept and return EMACS_INT, not int, because callers can pass values

6794 (string_escape_byte8, Fget_byte):
6795 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

6797 avoid mishandling large integers.

6813 to be a character. Avoid int overflow if max_char is close

6828 (uniprop_get_decoder, uniprop_get_encoder):
6829 Don't assume fixnum fits in int.
6830 * cmds.c (move_point): New function, that does the gist of

7488 (x_connection_closed):
7489 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7490 * xterm.h: Adjust decls to match defn changes elsewhere.
7491 (struct scroll_bar): Use struct vectorlike_header
7492 rather than rolling our own approximation.
7493 (SCROLL_BAR_VEC_SIZE): Remove; not used.
7495 2012-05-25 Glenn Morris <rgm@gnu.org>
7497 * lisp.mk (lisp): Update for more files being compiled now.
7499 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
7501 * lread.c: Remove `read_pure' which makes no difference.
7502 (read_pure): Remove var.
7503 (unreadpure): Remove function.
7504 (readevalloop): Don't call read_list with -1 flag.
7505 (read1, read_vector): Don't test read_pure any more.
7506 (read_list): Simplify.
7508 * fileio.c, character.h: Minor style tweaks.
7510 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
7512 * window.h (clip_changed): Remove useless declaration.
7514 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
7516 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
7517 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
7519 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
7522 This directory predates autoconf and is no longer needed nowadays.
7523 Move its few remaining bits of functionality to where they're needed.
7524 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
7525 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
7526 * m/template.h: Remove.
7527 * Makefile.in (M_FILE): Remove. All uses removed.
7528 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
7529 * lisp.h (USE_LSB_TAG):
7530 * mem-limits.h (EXCEEDS_LISP_PTR):
7531 Use VAL_MAX, not VALBITS, in #if.
7532 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
7533 (EMACS_UINT): Define unconditionally now.
7534 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
7535 (BITS_PER_EMACS_INT): New constants, replacing
7536 what used to be in config.h, but not useful in #if.
7537 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
7538 define them any more.
7539 (VAL_MAX): New macro.
7541 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
7542 BITS_PER_EMACS_INT, in #if.
7543 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
7544 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
7545 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
7546 * s/ms-w32.h (DATA_START):
7547 Move here from removed file m/intel386.h.
7548 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
7549 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
7551 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
7553 Assume C89 or later.
7554 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
7555 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
7557 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
7558 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
7559 * textprop.c, tparam.c (NULL): Remove.
7560 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
7561 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
7562 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
7563 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
7564 * xterm.c (input_signal_count): Assume volatile works.
7566 2012-05-21 Ken Brown <kbrown@cornell.edu>
7568 * xgselect.c (xg_select): Fix first argument in call to 'select'
7571 2012-05-20 Ken Brown <kbrown@cornell.edu>
7573 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
7574 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
7576 2012-05-19 Ken Brown <kbrown@cornell.edu>
7578 * xfns.c (x_in_use): Remove `static' qualifier.
7579 * xterm.h (x_in_use): Declare.
7580 * xgselect.c: Include xterm.h.
7581 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
7582 and `display_arg' (bug#9754).
7584 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
7586 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
7588 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
7589 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
7591 2012-05-18 Eli Zaretskii <eliz@gnu.org>
7593 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
7595 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
7596 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
7598 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
7599 reference to image_cache->refcount.
7600 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
7602 2012-05-17 Juri Linkov <juri@jurta.org>
7604 * search.c (Fword_search_regexp, Fword_search_backward)
7605 (Fword_search_forward, Fword_search_backward_lax)
7606 (Fword_search_forward_lax): Move functions to isearch.el
7607 (bug#10145, bug#11381).
7609 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
7611 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
7613 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
7615 * lread.c (init_obarray): Declare Qt and Qnil as special.
7617 2012-05-14 Glenn Morris <rgm@gnu.org>
7619 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
7620 Put "libexec" before "bin", for the sake of init_callproc_1.
7622 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7624 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
7626 * unexaix.c: Port to more-recent AIX compilers.
7627 (report_error, report_error_1, make_hdr, copy_sym)
7628 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
7629 Make arguments const char *, not char *, to avoid violations of C
7630 standard and to fix some AIX warnings reported by Gilles Pion.
7632 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7634 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
7635 already have overlays loaded.
7636 (handle_single_display_spec): Before returning without displaying
7637 fringe bitmap, synchronize the bidi iterator with the main display
7638 iterator, by calling iterate_out_of_display_property.
7639 (iterate_out_of_display_property): Detect buffer iteration by
7640 testing that it->string is a Lisp string.
7641 (get_next_display_element): When the current object is exhausted,
7642 and there's something on it->stack, call set_iterator_to_next to
7643 proceed with what's on the stack, instead of returning zero.
7644 (set_iterator_to_next): If called at the end of a Lisp string,
7645 proceed to consider_string_end without incrementing string
7646 position. Don't increment display vector index past the end of
7647 the display vector. (Bug#11417)
7648 (pos_visible_p): Don't report a position visible when move_it_to
7649 stopped at the last line of window, which happens to be scanned
7650 backwards by the bidi iteration. (Bug#11464)
7652 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7654 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7655 and right-margin display specs even if the spec is invalid or we
7656 are on a TTY, and thus unable to display on the fringes.
7657 That's because the text with the property will not be displayed anyway,
7658 so we need to signal to the caller that this is a "replacing"
7659 display spec. This fixes display when the spec is invalid or we
7662 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7664 * unexaix.c (make_hdr): Fix typo in prototype.
7665 This bug broke the build on AIX. Problem reported by Gilles Pion.
7667 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
7669 * keyboard.c (kbd_buffer_get_event): Read special events also in
7670 batch mode. (Bug#11415)
7672 2012-05-12 Glenn Morris <rgm@gnu.org>
7674 * ns.mk: Update for ns_appbindir no longer having trailing "/".
7676 2012-05-12 Eli Zaretskii <eliz@gnu.org>
7678 * lisp.mk (lisp): Add newcomment.elc.
7680 2012-05-12 Glenn Morris <rgm@gnu.org>
7682 * Makefile.in (MKDIR_P): New, set by configure.
7683 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
7685 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
7687 Remove unused function hourglass_started.
7688 * dispextern.h (hourglass_started):
7689 * w32fns.c (hourglass_started):
7690 * xdisp.c (hourglass_started): Remove.
7692 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7694 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7695 Update dependencies.
7697 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7699 * xgselect.c (xg_select): Put maxfds+1 into a var.
7700 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
7702 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7704 2012-05-10 Dave Abrahams <dave@boostpro.com>
7706 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7707 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7709 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7711 * dbusbind.c (xd_registered_buses): New internal Lisp object.
7712 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7713 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7714 Initialize xd_registered_buses.
7716 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7718 Untag more efficiently if USE_LSB_TAG.
7719 This is based on a proposal by YAMAMOTO Mitsuharu in
7720 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7721 For an admittedly artificial (nth 8000 longlist) benchmark on
7722 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7723 Emacs's overall text size by 1%.
7724 * lisp.h (XUNTAG): New macro.
7725 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7726 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7727 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7728 * eval.c (Fautoload):
7729 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7730 * frame.h (XFRAME): Use XUNTAG.
7732 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7733 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7734 Remove unportable assumptions about print widths of types like
7736 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7737 intptr_t when converting between pointer and integer, to avoid GCC
7738 warnings about wrong width.
7740 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7742 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7743 stack for each reader_thread, instead of defaulting to 8MB
7744 determined by the linker. This avoids failures in creating
7745 subprocesses on Windows 7, see the discussion in this thread:
7746 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7748 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7750 Fix up display of the *Minibuf-0* buffer in the mini window.
7751 * keyboard.c (read_char): Don't clear the echo area if there's no
7753 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7754 contents of *Minibuf-0*) if there's no message displayed in its stead.
7756 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7758 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7761 2012-05-06 Chong Yidong <cyd@gnu.org>
7763 * lisp.mk (lisp): Update.
7765 2012-05-05 Jim Meyering <meyering@redhat.com>
7767 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7769 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7771 * data.c (PUT_ERROR): New macro.
7772 (syms_of_data): Use it. Add new error type `user-error'.
7773 * undo.c (user_error): New function.
7774 (Fprimitive_undo): Use it.
7775 * print.c (print_error_message): Adjust print style for `user-error'.
7776 * keyboard.c (user_error): New function.
7777 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7779 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7781 Do not limit current-time-string to years 1000..9999.
7782 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7783 (Fcurrent_time_string): Support any year that is supported by the
7784 underlying localtime representation. Don't use asctime, as it
7785 has undefined behavior for years outside the range -999..9999.
7787 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7789 Fix race conditions involving setenv, gmtime, localtime, asctime.
7790 Without this fix, interrupts could mess up code that uses these
7791 nonreentrant functions, since setting TZ invalidates existing
7792 tm_zone or tzname values, and since most of these functions return
7793 pointers to static storage.
7794 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7795 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7796 Grow the critical sections to include not just invoking
7797 localtime/gmtime, but also accessing these functions' results
7798 including their tm_zone values if any, and any related TZ setting.
7799 (format_time_string): Last arg is now struct tm *, not struct tm **,
7800 so that the struct tm is saved in the critical section.
7801 All callers changed. Simplify allocation of initial buffer, partly
7802 motivated by the fact that memory allocation needs to be outside
7803 the critical section.
7805 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7807 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7808 with RESET_INTERVAL.
7810 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7811 Remove duplicated buffer name initialization.
7813 2012-05-02 Jim Meyering <jim@meyering.net>
7815 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7817 * xfns.c (x_window): Use xstrdup (Bug#11375).
7819 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7821 * xdisp.c (pos_visible_p): If already at a newline from the
7822 display string before the 'while' loop, don't walk back the glyphs
7823 from it3.glyph_row. Solves assertion violation when the display
7824 string begins with a newline (egg.el). (Bug#11367)
7826 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7828 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7831 2012-05-01 Glenn Morris <rgm@gnu.org>
7833 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7834 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7835 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7836 All were removed before 23.1.
7838 * dispnew.c: Remove HAVE_LIBNCURSES test;
7839 it is always true on relevant platforms.
7841 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7842 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7844 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
7846 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
7848 * .gdbinit (xpr): Remove checks for no longer existing misc types.
7849 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
7852 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
7854 Do not avoid creating empty evaporating overlays (Bug#9642).
7855 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7856 That is, do not delete an evaporating overlay if it becomes
7857 empty after its bounds are adjusted to fit within its buffer.
7858 This fix caused other problems, and I'm reverting it until we get
7859 to the bottom of them.
7861 2012-04-27 Chong Yidong <cyd@gnu.org>
7863 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7865 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7867 * xdisp.c (pos_visible_p): If the window start position is beyond
7868 ZV, start the display from buffer beginning. Prevents assertion
7869 violation in init_iterator when the minibuffer window is scrolled
7872 * window.c (window_scroll_pixel_based): Likewise.
7874 2012-04-27 Chong Yidong <cyd@gnu.org>
7876 * keymap.c (where_is_internal): Doc fix (Bug#10872).
7878 2012-04-27 Glenn Morris <rgm@gnu.org>
7880 * fileio.c (Fcopy_file, Fset_file_selinux_context):
7881 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
7883 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7885 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
7886 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
7888 2012-04-26 Eli Zaretskii <eliz@gnu.org>
7890 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7891 display element, check also the underlying string or buffer
7892 character. (Bug#11341)
7894 * w32menu.c: Include w32heap.h.
7895 (add_menu_item): If the call to AppendMenuW (via
7896 unicode_append_menu) fails, disable Unicode menus only if we are
7897 running on Windows 9X/Me.
7899 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7901 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
7902 (xgetint): Add missing shift for LSB tags.
7904 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7906 * keyboard.c (read_char): Don't wipe echo area for select window
7907 events: These might get delayed via `mouse-autoselect-window'
7910 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
7912 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
7913 manipulation of :loaded-from data.
7915 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
7917 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
7918 now a cons (bug#11311).
7920 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7922 Do not create empty overlays with the evaporate property (Bug#9642).
7923 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7924 if it becomes empty after its bounds are adjusted to fit within
7925 its buffer. Without this fix, in a nonempty buffer (let ((o
7926 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7927 yields an empty overlay that has the evaporate property, which is
7928 not supposed to happen.
7930 Fix minor GTK3 problems found by static checking.
7931 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7932 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7933 (struct _EmacsFixedClass, emacs_fixed_get_type):
7934 Move decls here from emacsgtkfixed.h, since they needn't be public.
7935 (emacs_fixed_get_type): Now static.
7936 (emacs_fixed_class_init): Omit unused local.
7937 (emacs_fixed_child_type): Remove; unused.
7938 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7939 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7940 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
7941 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
7942 (EMACS_FIXED_GET_CLASS): Remove; unused.
7943 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.

8030 * alloc.c: Handle unusual debugging option combinations.
8031 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
8032 since the two debugging options are incompatible.
8033 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
8035 (mem_init, mem_insert, mem_insert_fixup):
8036 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

8068 (print_object): Check for cycles even when print-circle is nil and
8069 print-gensym is t, but only check print_depth if print-circle is nil.
8071 2012-04-20 Chong Yidong <cyd@gnu.org>
8073 * process.c (wait_reading_process_output): If EIO occurs on a pty,

8129 New extern decls, to avoid calling undeclared functions.
8130 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
8131 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
8132 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

8149 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
8150 Remove decls. This fixes an "It stinks!".

8154 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
8156 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

8171 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
8172 * s/netbsd.h, s/sol2-6.h:
8173 Remove definition of GC_MARK_STACK, since the default now works.
8174 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
8175 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
8176 no longer the default.
8177 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
8179 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

8202 2012-04-11 Daniel Colascione <dancol@dancol.org>
8204 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
8205 against is gone. It's better to use vfork now so that when Cygwin
8206 gains a new, working vfork, we use it automatically (bug#10398).
8208 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

8229 being loaded (bug#10424).
8231 2012-04-09 Glenn Morris <rgm@gnu.org>

8261 * minibuf.c (Fread_variable): Callers changed.
8263 2012-04-09 Eli Zaretskii <eliz@gnu.org>
8265 * xdisp.c (set_cursor_from_row): If the display string appears in
8266 the buffer at position that is closer to point than the position
8267 after the display string, display the cursor on the first glyph of
8268 the display string. Fixes cursor display when a 'display' text
8269 property immediately follows invisible text. (Bug#11094)
8271 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
8273 composite.c: use 'double' consistently
8274 * composite.c (get_composition_id): Use 'double' consistently
8275 instead of converting 'float' to 'double' and vice versa; this is
8276 easier to understand and avoids a GCC warning.
8278 2012-04-09 Glenn Morris <rgm@gnu.org>
8280 * Makefile.in: Generate leim-list with bootstrap-emacs, in

8325 [!WINDOWSNT]: New macros.
8326 (init_libxml2_functions, libxml2_loaded_p): New functions.
8327 (parse_region): Call fn_xmlCheckVersion instead of using the macro
8328 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
8329 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
8330 Calls xmlCleanupParser only if libxml2 was loaded (or statically
8332 (Flibxml_parse_html_region, Flibxml_parse_xml_region):

8350 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
8351 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
8352 about subtle differences between FETCH_CHAR* and STRING_CHAR*
8353 macros related to unification of CJK characters. For the details,
8354 see the discussion following the message here:
8355 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
8357 2012-04-04 Chong Yidong <cyd@gnu.org>

8373 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
8374 position we get to after a call to move_it_to fails the
8375 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
8376 only if we wind up in a string from display property. (Bug#11063)
8378 * window.c (Fdelete_other_windows_internal): Invalidate the row
8379 and column information about mouse highlight, so that redisplay
8380 restores it after reallocating the glyph matrices. (Bug#7464)
8382 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
8383 string comes from a `display' text property, use the buffer
8384 position of that property as if we actually saw that position in
8386 (move_it_by_lines): Remove the assertion that
8387 "it->current_x == 0 && it->hpos == 0" which can be legitimately
8388 violated when there's a before-string at the beginning of a line.
8391 2012-03-30 Eli Zaretskii <eliz@gnu.org>

8397 (display_line): Call extend_face_to_end_of_line when the default
8398 face was remapped. (Bug#11068)
8400 2012-03-29 Eli Zaretskii <eliz@gnu.org>
8402 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
8404 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
8406 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
8408 2012-03-27 Glenn Morris <rgm@gnu.org>
8410 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
8413 2012-03-26 Kenichi Handa <handa@m17n.org>
8415 * dispextern.h (struct glyph): Fix previous change. Change the
8416 bit length of glyphless.ch to 25 (Bug#11082).
8418 2012-03-26 Chong Yidong <cyd@gnu.org>
8420 * keyboard.c (Vselection_inhibit_update_commands): New variable.
8421 (command_loop_1): Use it; inhibit selection update for
8422 handle-select-window too (Bug#8996).
8424 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
8426 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
8428 2012-03-25 Kenichi Handa <handa@m17n.org>
8430 * dispextern.h (struct glyph): Change the bit length of
8431 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
8433 2012-03-24 Eli Zaretskii <eliz@gnu.org>
8435 * s/ms-w32.h (tzname): Include time.h before redirecting to
8436 _tzname. Fixes the MSVC build. (Bug#9960)

8440 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
8443 * xterm.c (XTread_socket): Only modify handling_signal if
8444 !SYNC_INPUT. (Bug#11080)
8446 2012-03-23 Eli Zaretskii <eliz@gnu.org>
8448 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
8449 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
8450 when fetching a multibyte character consumes more bytes than
8451 CHAR_BYTES returns, due to unification of CJK characters in
8452 string_char. (Bug#11073)
8454 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
8456 * process.c (wait_reading_process_output): Handle pty disconnect
8457 by refraining from sending oneself a SIGCHLD (bug#10933).
8459 2012-03-22 Chong Yidong <cyd@gnu.org>

8474 * w32proc.c (Fw32_set_console_codepage)
8475 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
8478 2012-03-20 Chong Yidong <cyd@gnu.org>
8480 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
8481 to reflect default non-nil value of redisplay-dont-pause.
8483 2012-03-19 Kenichi Handa <handa@m17n.org>
8485 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
8486 it fit in a valid range (Bug#11003).
8488 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8490 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8491 that is not from display property, accept the row as a "cursor
8492 row" if one of the string's character has a non-nil `cursor'
8493 property. Fixes cursor positioning when there are newlines in
8494 overlay strings, e.g. in icomplete.el. (Bug#11035)
8496 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
8498 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
8500 2012-03-12 Chong Yidong <cyd@gnu.org>
8502 * eval.c (inhibit_lisp_code): Rename from
8503 inhibit_window_configuration_change_hook; move from window.c.
8505 * xfns.c (unwind_create_frame_1, Fx_create_frame):
8506 * window.c (run_window_configuration_change_hook)
8507 (syms_of_window): Callers changed.
8509 2012-03-11 Chong Yidong <cyd@gnu.org>

8518 is visible (Bug#10955).
8520 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
8522 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
8524 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
8526 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
8527 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8530 2012-03-03 Glenn Morris <rgm@gnu.org>
8532 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
8534 2012-03-02 Eli Zaretskii <eliz@gnu.org>
8536 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
8537 position past the first glyph_row that ends at ZV. (Bug#10902)
8538 (redisplay_window, next_element_from_string): Fix typos in
8540 (redisplay_window): Pass to move_it_vertically the margin in
8541 pixels, not in screen lines.
8543 2012-03-02 Glenn Morris <rgm@gnu.org>
8545 * buffer.c (buffer-list-update-hook): Doc fix.
8547 2012-02-29 Eli Zaretskii <eliz@gnu.org>
8549 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
8550 push_it before setting up the iterator for the first overlay
8551 string, even if we have an empty string loaded.
8552 (next_overlay_string): If there's an empty string on the iterator
8553 stack, pop the stack. (Bug#10903)
8555 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8557 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8558 Suggested by Stefan Monnier in
8559 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8560 * alloc.c (widen_to_Lisp_Object): New static function.
8561 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8562 and widening them to Lisp_Objects. This would work even if
8563 USE_LSB_TAG is defined and wide integers are used, which might
8564 happen in a future version of Emacs.
8566 2012-02-25 Chong Yidong <cyd@gnu.org>
8568 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
8571 * xselect.c (Fx_selection_exists_p): Doc fix.
8572 (x_clipboard_manager_save_all): Print an informative message
8573 before saving to clipboard manager.
8575 2012-02-24 Chong Yidong <cyd@gnu.org>
8577 * keyboard.c (process_special_events): Handle all X selection
8578 requests in kbd_buffer, not just the next one (Bug#8869).
8580 2012-02-23 Chong Yidong <cyd@gnu.org>
8582 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
8583 call when setting menu-bar-lines and tool-bar-lines parameters.
8584 (unwind_create_frame_1): New helper function.
8586 * window.c (inhibit_window_configuration_change_hook): New var.
8587 (run_window_configuration_change_hook): Obey it.
8588 (syms_of_window): Initialize it.
8590 2012-02-22 Chong Yidong <cyd@gnu.org>
8592 * xterm.c (x_draw_image_relief): Add missing type check for
8593 Vtool_bar_button_margin (Bug#10743).

8597 * fileio.c (Vfile_name_handler_alist): Doc fix.
8599 * buffer.c (Fget_file_buffer): Protect against invalid file
8600 handler return value.
8602 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
8604 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
8605 when computing $valmask.
8607 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8608 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8609 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8610 It's useless in that case, and it can cause problems on hosts
8611 that allocate halves of EMACS_INT values separately.
8612 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8613 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8614 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8615 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8616 it avoids undefined behavior on hosts where shifting right by more
8617 than the word width has undefined behavior.
8619 2012-02-19 Chong Yidong <cyd@gnu.org>
8621 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
8622 (Funhandled_file_name_directory, Ffile_name_as_directory)
8623 (Fdirectory_file_name, Fexpand_file_name)

8639 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
8641 2012-02-15 Chong Yidong <cyd@gnu.org>
8643 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
8644 marked as special. Also, starting docstrings with * is obsolete.
8646 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
8648 * gnutls.c (emacs_gnutls_write): Fix last change.
8650 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

8659 2012-02-12 Chong Yidong <cyd@gnu.org>
8661 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
8662 as that creates a dangerous corner case.
8664 * window.c (Fdelete_window_internal): Invalidate the mouse
8665 highlight (Bug#9904).
8667 2012-02-12 Glenn Morris <rgm@gnu.org>

8670 (Fx_get_selection_internal, Fx_disown_selection_internal)
8671 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
8672 * nsselect.m (Fx_own_selection_internal)
8673 (Fx_disown_selection_internal, Fx_selection_exists_p)
8674 (Fx_selection_owner_p, Fx_get_selection_internal):
8675 Sync docs and argument specs with the xselect.c versions.
8677 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
8679 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

8693 2012-02-09 Kenichi Handa <handa@m17n.org>
8695 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
8697 2012-02-07 Chong Yidong <cyd@gnu.org>
8699 * buffer.c (Fbuffer_local_variables)
8700 (buffer_lisp_local_variables): Handle unbound vars correctly;
8701 don't let Qunbound leak into Lisp.
8703 2012-02-07 Glenn Morris <rgm@gnu.org>
8705 * image.c (Fimagemagick_types): Doc fix.
8707 * image.c (imagemagick-render-type): Change it from a lisp object
8708 to an integer. Move the doc here from the lisp manual.

8711 2012-02-06 Chong Yidong <cyd@gnu.org>
8713 * doc.c (store_function_docstring): Avoid applying docstring of
8714 alias to base function (Bug#2603).
8716 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
8718 * .gdbinit (pp1, pv1): Remove redundant defines.
8721 2012-02-04 Chong Yidong <cyd@gnu.org>
8723 * nsterm.m: Declare a global (Bug#10694).
8725 2012-02-04 Eli Zaretskii <eliz@gnu.org>

8728 Include --enable-checking, if specified, in the return value.
8730 2012-02-04 Martin Rudalics <rudalics@gmx.at>
8732 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
8733 after rounding frame sizes. (Bug#9723)

8737 * keyboard.c (adjust_point_for_property): Don't position point
8738 before BEGV. (Bug#10696)
8740 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
8742 Handle overflow when computing char display width (Bug#9496).
8743 * character.c (char_width): Return EMACS_INT, not int.
8744 (char_width, c_string_width): Check for overflow when
8745 computing the width; this is possible now that individual
8746 characters can have unbounded width. Problem introduced
8747 by merge from Emacs 23 on 2012-01-19.
8749 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
8751 * dbusbind.c (Fdbus_register_method): Mention the return value

8764 2012-02-02 Kenichi Handa <handa@m17n.org>
8766 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
8767 0, do not call append_composite_glyph.
8769 2012-02-02 Kenichi Handa <handa@m17n.org>
8771 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
8773 (x_produce_glyphs): If the component of a composition is a null
8774 string, set it->pixel_width to 1 to avoid zero-width glyph.
8776 2012-02-01 Eli Zaretskii <eliz@gnu.org>
8778 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
8779 first 2 arguments are identical. This makes inserting large
8780 output from a subprocess an order of magnitude faster on
8781 MS-Windows, where all sbrk'ed memory is always contiguous.
8783 2012-01-31 Glenn Morris <rgm@gnu.org>
8785 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

8795 * s/gnu.h: Define POSIX_SIGNALS (Bug#10552).
8797 2012-01-28 Chong Yidong <cyd@gnu.org>

8824 since nil is not allowed anyway.
8826 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
8828 * process.c (read_process_output): Use p instead of XPROCESS (proc).

8835 Rewrite doc-strings.
8837 2012-01-19 Kenichi Handa <handa@m17n.org>
8839 * character.c (char_width): New function.
8840 (Fchar_width, c_string_width, lisp_string_width):
8841 Use char_width (Bug#9496).
8843 2012-01-16 Martin Rudalics <rudalics@gmx.at>
8845 * window.c (Vwindow_persistent_parameters): New variable.
8846 (Fset_window_configuration, save_window_save): Handle persistent
8849 2012-01-14 Eli Zaretskii <eliz@gnu.org>
8851 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid
8852 thrashing the stack of the thread. (Bug#9087)
8854 2012-01-12 Paul Eggert <eggert@cs.ucla.edu>
8856 * xdisp.c (rows_from_pos_range): Add parens as per gcc -Wparentheses.

8863 he end column for display of highlight that ends on a newline
8866 2012-01-11 Glenn Morris <rgm@gnu.org>
8868 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
8869 from load-path also when installation-directory is nil. (Bug#10208)
8871 2012-01-10 Glenn Morris <rgm@gnu.org>
8873 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
8875 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
8876 Update template values to be closer to their typical values these days.
8878 2012-01-09 Eli Zaretskii <eliz@gnu.org>
8880 * xdisp.c (rows_from_pos_range): Accept additional argument
8881 DISP_STRING, and accept any glyph in a row whose object is that
8882 string as eligible for mouse highlight. Fixes mouse highlight of
8883 display strings from overlays. (Bug#10464)
8885 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
8887 emacs: fix an auto-save permissions race condition (Bug#10400)
8888 * fileio.c (auto_saving_dir_umask): New static var.
8889 (Fmake_directory_internal): Use it.
8890 (do_auto_save_make_dir): Set it, instead of invoking chmod after
8891 creating the directory. The old code temporarily assigns
8892 too-generous permissions to the directory.
8893 (do_auto_save_eh): Clear it.
8894 (Fdo_auto_save): Catch all errors, not just file errors, so
8895 that the var is always cleared.
8897 2012-01-07 Eli Zaretskii <eliz@gnu.org>
8899 * search.c (scan_buffer): Pass character positions to
8900 know_region_cache, not byte positions. (Bug#6540)
8902 2012-01-07 LynX <_LynX@bk.ru> (tiny change)
8904 * w32.c (sys_rename): Report EXDEV when rename of a directory

9400 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
9401 is set, removing the need for VIRT_ADDRESS_VARIES.
9402 (PURE_P): Use a more-efficient implementation that needs just one
9403 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
9404 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
9405 to 4 (xorl, subq, cmpq, setbe).
9406 * alloc.c (pure): Always extern now, since that's the
9407 VIRT_ADDR_VARIES behavior.
9408 (PURE_POINTER_P): Use a single comparison, not two, for
9409 consistency with the new puresize.h.
9410 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
9411 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
9412 Remove VIRT_ADDR_VARIES no longer needed.
9414 2011-11-19 Eli Zaretskii <eliz@gnu.org>
9416 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
9417 (erase_phys_cursor, update_window_cursor, show_mouse_face)
9418 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
9419 behave as if the cursor position were at the window margin.
9421 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
9422 and the cursor position is out of bounds, behave as if the cursor
9423 position were at the window margin. (Bug#10075)
9425 2011-11-18 Chong Yidong <cyd@gnu.org>
9427 * window.c (Fwindow_combination_limit): Make first argument
9428 non-optional, since it is meaningless for live windows like the

9442 * dispnew.c (swap_glyph_pointers): Swap the used[] arrays and the
9443 hash values of the two rows.
9444 (copy_row_except_pointers): Preserve the used[] arrays and the
9445 hash values of the two rows. (Bug#10035)
9446 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
9448 * xdisp.c (row_hash): New function, body extracted from
9449 compute_line_metrics.
9450 (compute_line_metrics): Call row_hash, instead of computing the
9453 * dispnew.c (verify_row_hash): Call row_hash for computing the
9454 hash code of a row, instead of duplicating code from xdisp.c.
9456 * dispextern.h (row_hash): Add prototype.
9458 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
9460 * frame.c (delete_frame): Don't delete the terminal when the last
9461 X frame is closed if emacs is built with GTK toolkit.

9492 * image.c (imagemagick_load_image): Fix typo.
9494 2011-11-14 Eli Zaretskii <eliz@gnu.org>
9496 * xdisp.c (display_line): Move the call to
9497 highlight_trailing_whitespace before the call to
9498 compute_line_metrics, since the latter needs to see the final
9499 faces of all the glyphs to compute ROW's hash value.
9500 Fixes assertion violations in row_equal_p. (Bug#10035)
9502 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
9504 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

9509 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
9510 with user-defined heap size. Bump the default size of the temacs
9511 heap to 27MB, to avoid memory warning when running temacs.
9512 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
9514 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

9535 * w32fns.c (unwind_create_frame): Use Fmemq to check if frame is in
9536 Vframe_list (Bug#9999).
9538 2011-11-11 Dmitry Antipov <dmantipov@yandex.ru>
9540 * xdisp.c (syms_of_xdisp): Remove duplicated definition of Qtext.

9561 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
9563 Avoid some portability problems by eschewing 'extern inline' functions.
9564 The trivial performance wins aren't worth the portability hassles; see
9565 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
9567 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
9568 (window_box_width, window_box_left, window_box_left_offset)
9569 (window_box_right, window_box_right_offset): Undo previous change,
9570 by removing the "extern"s.
9571 * intervals.c (adjust_intervals_for_insertion)
9572 (adjust_intervals_for_deletion): Undo previous change,
9573 making these static again.
9574 (offset_intervals, temp_set_point_both, temp_set_point)
9575 (copy_intervals_to_string): No longer inline.
9576 * xdisp.c (window_text_bottom_y, window_box_width)

9615 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
9616 This is also needed for porting to any host where GC_MARK_STACK is
9617 not GC_MAKE_GCPROS_NOOPS.
9618 (which_symbols): Use it.
9620 2011-11-07 Kenichi Handa <handa@m17n.org>

9633 * xmenu.c (cleanup_widget_value_tree): New function.
9634 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
9635 calling free_menubar_widget_value_tree directly (Bug#9830).

9641 (window_box_width, window_box_left, window_box_left_offset)
9642 (window_box_right, window_box_right_offset): Declare extern.
9643 Otherwise, these inline functions do not conform to C99 and
9644 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
9645 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
9646 * intervals.c (adjust_intervals_for_insertion)
9647 (adjust_intervals_for_deletion): Now extern, because otherwise the
9648 extern inline functions 'offset_intervals' couldn't refer to it.
9649 (static_offset_intervals): Remove.
9650 (offset_intervals): Rewrite using the old contents of
9651 static_offset_intervals. The old version didn't conform to C99
9652 because an extern inline function contained a reference to an
9653 identifier with static linkage.
9655 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
9657 * keyboard.c (interrupt_signal): Don't call kill-emacs while in
9660 2011-11-06 Eli Zaretskii <eliz@gnu.org>
9662 * xdisp.c (init_iterator, reseat_to_string): Don't set the
9663 iterator's bidi_p flag if Vpurify_flag is non-nil. (Bug#9963)
9664 (Fcurrent_bidi_paragraph_direction): If Vpurify_flag is non-nil,
9665 return Qleft_to_right.
9667 2011-11-06 Chong Yidong <cyd@gnu.org>

9672 (Fwindow_use_time, Fwindow_total_size, Fwindow_normal_size)
9673 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
9674 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
9675 (Fwindow_vscroll): Doc fix.
9676 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
9677 argument, since it makes no sense to pass a live window and for
9678 consistency with window-child.

9700 initialization code to keep similarity to xfns.c after changes
9703 2011-11-05 Jan Djärv <jan.h.d@swipnet.se>
9705 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
9706 (unwind_create_frame): New function (Bug#9943).
9707 (Fx_create_frame): Restructure code to be more similar to the one in
9708 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
9709 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
9710 Move terminal->reference_count++ just before making the frame official
9713 * nsterm.m (x_free_frame_resources): New function.
9714 (x_destroy_window): Move code to x_free_frame_resources.
9716 * xfns.c (unwind_create_frame): Fix comment.
9717 (Fx_create_frame, x_create_tip_frame):
9718 Move terminal->reference_count++ just before making the frame
9719 official. Move initialization of image_cache_refcount and
9720 dpyinfo_refcount before calling init_frame_faces (Bug#9943).
9722 2011-11-05 Eli Zaretskii <eliz@gnu.org>
9724 Support MSVC build with newer versions of Visual Studio.
9725 * makefile.w32-in (TAGS-gmake): Don't use $(patsubst ...), as

9871 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
9873 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
9875 2011-10-28 Eli Zaretskii <eliz@gnu.org>
9877 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
9878 <oslsachem@gmail.com> for helping to debug this.
9880 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
9881 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
9882 (g_b_init_get_glyph_outline_w): New static variables.
9883 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
9884 (GetGlyphOutlineW_Proc): New typedefs.
9885 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
9886 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
9888 (w32font_open_internal, compute_metrics):
9889 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
9890 instead of calling the "wide" APIs directly.
9892 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
9894 * w32.h (syms_of_w32font): Add prototype.
9896 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9898 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
9899 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
9900 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
9901 (Fmove_to_window_line): Doc fix.
9903 2011-10-27 Chong Yidong <cyd@gnu.org>
9905 * process.c (make_process): Set gnutls_state to NULL.
9907 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
9908 non-NULL, regardless of GNUTLS_INITSTAGE.
9909 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
9910 an error. Set process slots as soon as we allocate them.
9912 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
9914 2011-10-27 Chong Yidong <cyd@gnu.org>
9916 * gnutls.c (emacs_gnutls_deinit): New function.
9917 Deallocate credentials structures as well as calling gnutls_deinit.
9918 (Fgnutls_deinit, Fgnutls_boot): Use it.
9920 * process.c (make_process): Initialize GnuTLS credentials to NULL.
9921 (deactivate_process): Call emacs_gnutls_deinit.
9923 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9925 * image.c (x_create_x_image_and_pixmap):
9926 * w32.c (sys_rename, w32_delayed_load):
9927 * w32font.c (fill_in_logfont):
9928 * w32reg.c (x_get_string_resource): Silence compiler warnings.
9930 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
9932 * w32fns.c (w32_default_color_map): New function,
9933 extracted from Fw32_default_color_map.
9934 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
9936 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
9938 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
9940 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
9942 * keyboard.c (test_undefined): New function (bug#9751).
9943 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
9945 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
9947 * sysdep.c (init_sys_modes): Fix the check for the controlling
9948 terminal (Bug#6649).
9950 2011-10-20 Eli Zaretskii <eliz@gnu.org>
9952 * dispextern.h (struct bidi_it): New member next_en_type.
9954 * bidi.c (bidi_line_init): Initialize the next_en_type member.
9955 (bidi_resolve_explicit_1): When next_en_pos is valid for the
9956 current character, check also for next_en_type being WEAK_EN.
9957 (bidi_resolve_weak): Don't enter the expensive loop if the current
9958 position is before next_en_pos. Record the bidi type of the first
9959 non-ET, non-BN character we find, in addition to its position.
9960 (bidi_level_of_next_char): Invalidate next_en_type when
9961 next_en_pos is over-stepped.
9963 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
9965 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
9966 * editfns.c: Rewrite current-time-zone so that it invokes
9967 the equivalent of (format-time-string "%Z") to get the time zone name.
9968 This fixes a bug when the time zone name contains characters that
9969 need converting from the system time locale to Emacs internal format.
9970 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9971 that patch fixed format-time-string to do the conversion, but
9972 I forgot to fix current-time-zone.
9973 (format_time_string): New function, containing most of
9974 what Fformat_time_string used to contain.
9975 (Fformat_time_string): Rewrite in terms of format_time_string.
9976 This doesn't change this function's behavior.
9977 (current-time-zone): Rewrite to use format_time_string.
9978 This fixes the bug reported by Michael Schierl in
9979 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9980 Jason Rumney's 2007-06-07 change worked around this bug, but
9982 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9984 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9986 * xdisp.c (start_display): If the character at POS is displayed
9987 via a display vector, reset IT->current.dpvec_index to zero.
9988 (try_window_reusing_current_matrix): If a line ends in a display
9989 vector or the next line starts in a display vector, continue
9990 redrawing the window even though the character position of
9991 start_row was reached.
9994 2011-10-18 Chong Yidong <cyd@gnu.org>
9996 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9997 with nobreak-char-display too.
9999 2011-10-18 Eli Zaretskii <eliz@gnu.org>
10001 Fix part 3 of bug#9771.
10002 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
10003 (bidi_resolve_neutral): Don't enter the expensive loop looking for
10004 non-neutral characters if the current character is a paragraph
10005 separator (a.k.a. Newline). This avoids running the same
10006 expensive loop twice, once when we consume the preceding newline
10007 and the other time when the line actually needs to be displayed.
10008 Avoid the loop when we see neutrals on the base embedding level
10009 following a character whose directionality is the same as the
10010 paragraph's. This avoids running the expensive loop when a line
10011 ends in a long sequence of neutrals, like control characters.
10012 Add assertion against STRONG_AL type. Slightly rearrange code
10013 that determines the type of a neutral given the first non-neutral
10015 (bidi_level_of_next_char): Set next_en_pos to zero when
10016 invalidating its info.
10018 2011-10-17 Eli Zaretskii <eliz@gnu.org>
10020 * xdisp.c (push_display_prop): Determine whether to record string
10021 or buffer position by IT->string, not by IT->method. Allow
10022 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
10023 (move_it_vertically_backward): Don't look for character position
10024 immediately after the newline when in a continuation line.
10027 2011-10-15 Martin Rudalics <rudalics@gmx.at>
10029 * window.c (coordinates_in_window): Rewrite and delabelize
10030 vertical border check. (Bug#5357) (Bug#9618)
10032 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
10034 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
10035 errors in XSetWindowBorder (bug#9310).
10037 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
10039 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
10040 avoid crash when xmalloc overrun checking is enabled.
10042 2011-10-13 Eli Zaretskii <eliz@gnu.org>
10044 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
10045 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
10046 cursor motion with <left> and <right> arrow keys.
10048 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
10049 some callers set that themselves.
10051 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10053 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
10054 display string and the previous row comes from the same string and
10055 is empty. (Bug#9739) (Bug#9738)
10057 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
10059 * doc.c (get_doc_string): Encode file name (bug#9735).
10061 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10063 * bidi.c (bidi_level_of_next_char):
10064 * xdisp.c (get_visually_first_element): Remove old incorrect
10065 comments regarding the Unicode Line Separator character.
10067 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
10069 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
10071 * alloc.c (Fgc_status): Do not access beyond zombies array
10072 boundary if nzombies > MAX_ZOMBIES.
10073 * alloc.c (dump_zombies): Add missing format specifier.
10075 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
10077 * xdisp.c (set_cursor_from_row): Simplify conditionals,
10078 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
10080 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
10081 Some packages use them to denote characters with modifiers.
10083 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
10085 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
10086 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
10087 matching a pp-number. Rename parameter var to var1.
10089 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
10091 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
10093 2011-10-08 Glenn Morris <rgm@gnu.org>
10095 * callint.c (Fcall_interactively): Give a more explicit error for the
10096 'c' case with a non-character input. (Bug#8479)
10098 2011-10-08 Eli Zaretskii <eliz@gnu.org>
10100 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
10102 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
10103 lines that are hscrolled on the left.
10105 * dispnew.c (buffer_posn_from_coords): Account for a possible
10106 presence of header-line. (Bug#4426)
10108 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
10110 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
10111 Don't advertise functionality which we discourage or doesn't work.
10113 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
10115 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
10116 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
10117 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
10118 this makes Emacs dump core during garbage collection on rare
10119 occasions. sizeof is obviously inferior to offsetof here, so
10120 stick with offsetof.
10121 (GC_POINTER_ALIGNMENT): New macro.
10122 (mark_memory): Omit 3rd (offset) arg; caller changed.
10123 Don't assume EMACS_INT alignment is the same as pointer alignment.
10125 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
10127 * keyboard.c (read_key_sequence_remapped): New var.
10128 (read_key_sequence): Compute remapping in the right buffer.
10129 (command_loop_1): Use read_key_sequence's remapping directly.
10131 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
10133 * dired.c (file_name_completion): Don't expand file name.
10134 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
10135 before checking file name handler.
10137 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
10138 they've been requested explicitly (bug#9591).
10140 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
10142 * keymap.c (Fsingle_key_description): Use make_specified_string
10143 instead of build_string to build string from push_key_description.
10146 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10148 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
10149 This fixes a Y2038 bug on 64-bit hosts.
10150 * buffer.c (reset_buffer):
10151 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
10152 (Fclear_buffer_auto_save_failure):
10153 Use 0, not -1, to represent an unset failure time, since time_t
10154 might not be signed.
10156 Remove dependency on glibc malloc internals.
10157 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10158 Move back here from lisp.h, but with their new implementations.
10159 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10160 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
10161 * charset.c (charset_table_init): New static var.
10162 (syms_of_charset): Use it instead of xmalloc. This removes a
10163 dependency on glibc malloc internals. See Eli Zaretskii's comment in
10164 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
10165 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10166 Move back to alloc.c.
10167 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10168 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
10170 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
10172 * nsterm.m (windowDidResize): Call x_set_window_size only when
10173 ns_in_resize is true. Otherwise set pixelwidth/height and
10174 call change_frame_size (Bug#9628).
10176 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10178 Port --enable-checking=all to Fedora 14 x86-64.
10179 * charset.c (syms_of_charset): Also account for glibc malloc's
10180 internal overhead when calculating the initial malloc maximum.
10182 Port --enable-checking=all to Fedora 14 x86.
10183 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10185 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
10186 (overrun_check_realloc, overrun_check_free):
10187 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
10188 That way, xmalloc returns a properly-aligned pointer even if
10189 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
10190 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
10191 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
10192 into account when calculating the initial malloc maximum.
10193 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10194 Move here from alloc.c, so that charset.c can use it too.
10195 Properly align; the old code wasn't right for common 32-bit hosts
10196 when configured with --enable-checking=all.
10197 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10198 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
10200 2011-09-29 Eli Zaretskii <eliz@gnu.org>
10202 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
10205 2011-09-28 Eli Zaretskii <eliz@gnu.org>
10207 * xdisp.c (compute_display_string_end): If there's no display
10208 string at CHARPOS, return -1.
10210 * bidi.c (bidi_fetch_char): When compute_display_string_end
10211 returns a negative value, treat the character as a normal
10212 character not covered by a display string. (Bug#9624)
10214 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
10216 * lread.c (Fread_from_string): Fix typo in docstring.
10218 2011-09-27 Eli Zaretskii <eliz@gnu.org>
10220 * xdisp.c (handle_invisible_prop): If invisible text ends on a
10221 newline, reseat the iterator instead of bidi-iterating there one
10222 character at a time. (Bug#9610)
10223 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
10224 TO_CHARPOS if the bidi iterator is at base embedding level.
10226 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
10228 * lread.c (readevalloop): Use correct code for NBSP.
10229 (read1): Likewise. (Bug#9608)
10231 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
10233 * dbusbind.c (Fdbus_register_signal): When service is not
10234 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
10236 2011-09-25 Glenn Morris <rgm@gnu.org>
10238 * buffer.c (truncate-lines): Doc fix.
10240 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
10242 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
10243 (Fset_window_next_buffers): Doc fix.
10245 2011-09-24 Glenn Morris <rgm@gnu.org>
10247 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
10249 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
10251 Fix minor problems found by static checking.
10252 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
10253 * indent.c (Fvertical_motion): Fix == vs = typo.
10255 2011-09-24 Eli Zaretskii <eliz@gnu.org>
10257 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
10258 Default value is now t. Doc fix.
10260 * indent.c (Fvertical_motion): Compute and apply the overshoot
10261 logic when moving up, not only when moving down. Fix the
10262 confusing name and values of the it_overshoot_expected variable;
10263 logic changes accordingly. (Bug#9254) (Bug#9549)
10265 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
10266 CHARPOS is covered by a display string which includes newlines.
10267 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
10268 is covered by a display string with embedded newlines.
10270 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
10272 * dbusbind.c (Fdbus_register_signal): Add match rule to
10273 Vdbus_registered_objects_table. (Bug#9581)
10274 (Fdbus_register_method, Vdbus_registered_objects_table):
10277 2011-09-24 Jim Meyering <meyering@redhat.com>
10279 do not ignore write error for any output size
10280 The previous change was incomplete.
10281 While it makes emacs --batch detect the vast majority of stdout
10282 write failures, errors were still ignored whenever the output size is
10283 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
10284 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
10285 && echo FAIL: ignored write error
10286 FAIL: ignored write error
10287 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
10288 && echo FAIL: ignored write error
10289 FAIL: ignored write error
10290 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
10292 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
10294 * emacs.c (Fkill_emacs): In noninteractive mode exit
10295 non-successfully if a write error occurred on stdout. (Bug#9574)
10297 2011-09-21 Eli Zaretskii <eliz@gnu.org>
10299 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
10302 * dispextern.h (struct it): Update the comment documenting what
10305 2011-09-20 Eli Zaretskii <eliz@gnu.org>
10307 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
10308 a display string, extend search for cursor position to end of row.
10309 (find_row_edges): If the row ends in a newline from a display
10310 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
10311 Handle the case of a display string with multiple newlines.
10312 (Fcurrent_bidi_paragraph_direction): Fix search for previous
10313 non-empty line. Fixes confusing cursor motion with arrow keys at
10314 the beginning of a line that starts with whitespace.
10316 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>

10321 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
10323 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
10324 boolean (Bug#9154).
10326 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10328 * xdisp.c (display_line): Record maximum and minimum buffer
10329 positions even if no glyphs were produced (e.g., by a zero-width
10330 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
10331 buffer positions that will be removed from the glyph row because
10333 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
10334 column is beyond frame width: don't subtract 1 "pixel" when
10335 computing width of the stretch.
10336 (reseat_at_next_visible_line_start): Undo the change made on
10337 2011-09-17 that saved paragraph information and restored it after
10338 the call to `reseat'. (Bug#9545)
10340 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10342 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
10343 and turn window cursor on if cleared (Bug#9415).
10345 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
10347 * search.c (boyer_moore): Take unibyte characters from pattern
10348 literally. (Bug#9458)
10350 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10352 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
10354 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
10356 Fix minor problem found by static checking.
10357 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
10358 initialized, to pacify gcc -Wuninitialized.
10360 * fileio.c: Report proper errno when syscall falls.
10361 (Finsert_file_contents): Save and restore errno,
10362 so that report_file_error outputs the correct diagnostic.
10363 (Fwrite_region) [CLASH_DETECTION]: Likewise.
10365 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10367 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
10369 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10371 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
10372 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
10374 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10376 * xdisp.c (reseat_at_next_visible_line_start): Keep information
10377 about the current paragraph and restore it after the call to reseat.
10379 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
10380 (bidi_find_paragraph_start): Search back for paragraph beginning
10381 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
10382 (bidi_move_to_visually_next): Only trigger paragraph-related
10383 computations when the last character is a newline or at EOB, not
10384 just any NEUTRAL_B. (Bug#9470)
10386 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
10387 truncated lines if point is covered by a display string. (Bug#9524)
10389 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
10391 * xselect.c: Relax test for outgoing X longs (Bug#9498).
10392 (cons_to_x_long): New function.
10393 (lisp_data_to_selection_data): Use it. Correct the test for
10394 short-versus-long data; it was negated. Break out of vector
10395 loop, for efficiency, when a long datum is discovered.
10397 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
10399 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
10401 2011-09-16 Eli Zaretskii <eliz@gnu.org>
10403 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
10404 GCC PR/17406) by declaring this function with external scope.
10406 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10408 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
10409 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
10411 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
10413 * editfns.c (Fformat): Correctly handle text properties on "%%".

10421 * xdisp.c (get_next_display_element)
10422 (fill_composite_glyph_string): Add comments about special meaning
10423 of TAB characters in a composition.
10425 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10427 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
10428 This occurs when processing a multibyte format.
10429 Problem reported by Wolfgang Jenker.
10431 2011-09-15 Johan Bockgård <bojohan@gnu.org>
10433 * xdisp.c (try_cursor_movement): Only check for exact match if
10434 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
10436 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10438 Remove unused external symbols.
10439 * dispextern.h (calc_pixel_width_or_height): Remove decl.
10440 * xdisp.c (calc_pixel_width_or_height): Now static.
10441 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
10442 * indent.c (check_display_width):
10443 * w32term.c: Fix comment to match code.
10444 * xterm.c, xterm.h (x_catching_errors): Remove.
10446 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10448 * xselect.c: Use signed conversions more consistently (Bug#9498).
10449 (selection_data_to_lisp_data): Assume incoming selection data are
10450 signed integers, not unsigned. This is to be consistent with
10451 outgoing selection data, which was modified to use signed integers
10452 in as part of the fix to Bug#9196 in response to Jan D.'s comment
10453 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
10454 expects long, not unsigned long.
10456 2011-09-14 Eli Zaretskii <eliz@gnu.org>
10458 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
10459 computation of loop end. Reported by Johan Bockgård
10462 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
10464 * frame.c (Fother_visible_frames_p): Function deleted.
10466 2011-09-12 Eli Zaretskii <eliz@gnu.org>
10468 * indent.c (compute_motion): Process display vector front to back
10469 rather than the other way around. (Bug#2496)
10471 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
10473 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
10475 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
10477 * minibuf.c (Fread_from_minibuffer): Doc fix.
10479 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10481 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
10482 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
10484 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
10486 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
10487 value for non-existent files.
10489 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10491 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10492 set its "size" to -1. This will set the modtime_size field of
10493 the corresponding buffer to -1, which is what
10494 verify-visited-file-modtime expects for files that do not exist.
10497 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
10499 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10501 * lisp.h: ... from here. push_key_description is no longer
10502 defined in keyboard.c, so its declaration should not be in
10503 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10504 logically belongs with push_key_description.
10506 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10508 * buffer.h: Include <sys/types.h> instead of <time.h>.
10509 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
10510 Problem reported by Herbert J. Skuhra.
10512 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
10514 * xml.c (parse_region): Make the parsing work for
10515 non-comment-starting XML files again (bug#9144).
10517 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
10519 * image.c (gif_load): Fix calculation of bottom and right corner.
10522 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10524 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10525 redisplay in small windows.
10527 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10529 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10531 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10533 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10534 Operate on live windows only.
10536 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10538 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10540 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10542 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10543 only under bidi iteration.
10545 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10547 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10549 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10551 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10552 Without this fix, the command to link temacs failed due to an
10553 undefined symbol __builtin_isnan. This is because
10554 /usr/include/iso/math_c99.h #defines isnan(x) to
10555 __builtin_isnan(x), but the bundled gcc, which identifies itself
10556 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10558 * floatfns.c (isnan): #undef, and then #define to a clone of
10560 (Fisnan): Always define, since it's always available now.
10561 (syms_of_floatfns): Always define isnan at the Lisp level.
10563 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10565 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10567 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10569 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10570 The previous code assumed that file offsets (off_t values) fit in
10571 EMACS_INT variables, which is not true on typical 32-bit hosts.
10572 The code messed up by falsely reporting buffer overflow in cases
10573 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10574 when "big" contains more than 2**29 bytes, even though this
10575 inserts just one byte and does not overflow the buffer.
10576 (Finsert_file_contents): Store file offsets as off_t
10577 values, not as EMACS_INT values. Check for overflow when
10578 converting between EMACS_INT and off_t. When checking for
10579 buffer overflow or for overlap, take the offsets into account.
10580 Don't use EMACS_INT for small values where int suffices.
10581 When checking for overlap, fix a typo: ZV was used where
10582 ZV_BYTE was intended.
10583 (Fwrite_region): Don't assume off_t fits into 'long'.
10584 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10586 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10588 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10590 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10592 sprintf-related integer and memory overflow issues (Bug#9412).
10594 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10595 (esprintf, exprintf, evxprintf): New functions.
10596 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10597 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10598 (modify_event_symbol): Do not assume that the length of
10599 name_alist_or_stem is safe to alloca and fits in int.
10600 (Fexecute_extended_command): Likewise for function name and binding.
10601 (Frecursion_depth): Wrap around reliably on integer overflow.
10602 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10603 since some callers pass EMACS_INT values.
10604 (Fsingle_key_description): Don't crash if symbol name contains more
10605 than MAX_ALLOCA bytes.
10606 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10607 (get_minibuffer): Arg is now EMACS_INT, not int.
10608 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10609 (esprintf, exprintf, evxprintf): New decls.
10610 * window.h (command_loop_level, minibuf_level): Reflect API changes.
10612 * dbusbind.c (signature_cat): New function.
10613 (xd_signature, Fdbus_register_signal):
10614 Do not overrun buffer; instead, report string overflow.
10616 * dispnew.c (add_window_display_history): Don't overrun buffer.
10617 Truncate instead; this is OK since it's just a log.
10619 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10620 even if the time zone offset is outlandishly large.
10621 Don't mishandle offset == INT_MIN.
10623 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10624 when creating daemon; the previous buffer-overflow check was incorrect.
10626 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10627 which has the guts of the old verror function.
10629 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10630 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10632 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10633 (font_unparse_xlfd): Don't blindly alloca long strings.
10634 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10635 fits in int, when using sprintf. Use single snprintf to count
10636 length of string rather than counting it via multiple sprintfs;
10637 that's simpler and more reliable.
10638 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10639 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10640 sprintf, in case result does not fit in int.
10642 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10643 (fontset_from_font): Print it.
10645 * frame.c (tty_frame_count): Now printmax_t, not int.
10646 (make_terminal_frame, set_term_frame_name): Print it.
10647 (x_report_frame_params): In X, window IDs are unsigned long,
10648 not signed long, so print them as unsigned.
10649 (validate_x_resource_name): Check for implausibly long names,
10650 and don't assume name length fits in 'int'.
10651 (x_get_resource_string): Don't blindly alloca invocation name;
10652 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10655 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10656 (xg_check_special_colors, xg_set_geometry):
10657 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10659 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10660 Use esprintf, not sprintf, in case result does not fit in int.
10662 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10663 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10664 it as a large positive number.
10665 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10666 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10668 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10669 in case result does not fit in int.
10671 * print.c (float_to_string): Detect width overflow more reliably.
10672 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10673 buffer overrun. Don't assume list length fits in 'int'. Treat
10674 print length of 0 as 0, not as infinity; to be consistent with other
10675 uses of print length in this function. Don't overflow print length
10676 index. Don't assume hash table size fits in 'long', or that
10677 vectorlike size fits in 'unsigned long'.
10679 * process.c (make_process): Use printmax_t, not int, to format
10680 process-name gensyms.
10682 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10684 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10685 to avoid potential buffer overrun.
10687 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10688 if X resource line is longer than 512 bytes.
10690 * xfns.c (x_window): Make sprintf buffer a bit bigger
10691 to avoid potential buffer overrun.
10693 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10695 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10697 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10699 Integer overflow fixes for scrolling, etc.
10700 Without these, Emacs silently mishandles large integers sometimes.
10701 For example, "C-u 4294967297 M-x recenter" was treated as if
10702 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10704 * xdisp.c (try_window_id): Check Emacs fixnum range before
10705 converting to 'int'.
10707 * window.c (window_scroll_line_based, Frecenter):
10708 Check that an Emacs fixnum is in range before assigning it to 'int'.
10709 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10710 values converted from Emacs fixnums.
10711 (Frecenter): Don't wrap around a line count if it is out of 'int'
10712 range; instead, treat it as an extreme value.
10713 (Fset_window_configuration, compare_window_configurations):
10714 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10716 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10717 that can exceed INT_MAX. Check that EMACS_INT value is in range
10718 before assigning it to the (possibly-narrower) index.
10719 (match_limit): Don't assume that a fixnum can fit in 'int'.
10721 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10724 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10725 (Fvertical_motion): Don't wrap around LINES values that don't fit
10726 in 'int'. Instead, treat them as extreme values. This is good
10727 enough for windows, which can't have more than INT_MAX lines anyway.
10729 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10731 * Require libxml/parser.h to avoid compilation warning.
10733 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10735 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10736 since this reportedly can destroy thread storage.
10738 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10740 * syntax.c (find_defun_start): Update all cache variables if
10741 exiting early (Bug#9401).
10743 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10745 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10747 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10748 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10749 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10751 * term.c (tty_append_glyph): New function.
10752 (produce_stretch_glyph): Static function and its prototype deleted.
10754 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10757 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10759 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10760 when checking :margin (Bug#9390).
10761 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10762 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10763 so that the name doesn't mislead. All uses changed.
10765 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10767 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
10770 2011-08-27 Eli Zaretskii <eliz@gnu.org>
10772 * xdisp.c (move_it_to): Don't bail out early when reaching
10773 position beyond to_charpos, if we are scanning backwards.
10774 (move_it_vertically_backward): When DY == 0, make sure we get to
10775 the first character in the line after the newline.
10777 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10779 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10780 (ccl_driver): Do not generate an out-of-range pointer.
10781 (Fccl_execute_on_string): Remove unnecessary check for
10782 integer overflow, noted by Stefan Monnier in
10783 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10784 Remove a FIXME that didn't need fixing.
10785 Simplify the newly-introduced buffer reallocation code.
10787 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10789 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10791 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10793 Integer and memory overflow issues (Bug#9196).
10795 * doc.c (get_doc_string): Rework so that
10796 get_doc_string_buffer_size is the actual buffer size, rather than
10797 being 1 less than the actual buffer size; this makes xpalloc more
10800 * image.c (x_allocate_bitmap_record, cache_image):
10801 * xselect.c (Fx_register_dnd_atom):
10802 Simplify previous changes by using xpalloc.
10804 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10805 since either will do and ptrdiff_t is convenient with xpalloc.
10807 * charset.c (charset_table_size)
10808 (struct charset_sort_data.priority): Now ptrdiff_t.
10809 (charset_compare): Don't overflow if priorities differ greatly.
10810 (Fsort_charsets): Don't assume list length fits in int.
10811 Check for size-calculation overflow when allocating sort data.
10812 (syms_of_charset): Allocate an initial charset table that is
10813 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10815 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10817 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10818 The actual value is always <= INT_MAX, and leaving it unsigned made
10819 overflow checking harder.
10821 * dispextern.h (struct glyph_matrix.rows_allocated)
10822 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10823 with xpalloc. The values are still always <= INT_MAX.
10825 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10827 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10828 (SAFE_NALLOCA): New macro.
10830 * region-cache.c (struct boundary.pos, find_cache_boundary)
10831 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10832 (set_cache_region, invalidate_region_cache)
10833 (revalidate_region_cache, know_region_cache, region_cache_forward)
10834 (region_cache_backward, pp_cache):
10835 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10836 so that ptrdiff_t * can be passed to xpalloc.
10837 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
10838 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
10839 (pp_cache): Don't assume cache_len fits in int.
10840 * region-cache.h: Adjust extern decls to match.
10842 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
10843 EMACS_INT, since either will do, for xpalloc.
10845 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
10846 (xnmalloc, xnrealloc, xpalloc): New functions.
10848 * bidi.c (bidi_shelve_header_size): New constant.
10849 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
10850 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
10852 * bidi.c (bidi_cache_shrink):
10853 * buffer.c (overlays_at, overlays_in, record_overlay_string)
10855 Don't update size of array until after memory allocation succeeds,
10856 because xmalloc/xrealloc may not return.
10857 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10858 now that we have proper integer overflow checking.
10859 (record_overlay_string, overlay_strings): Catch overflows when
10860 calculating size of overlay_str_buf.
10862 * callproc.c (Fcall_process): Check for size overflow when
10863 calculating size of args2.
10864 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
10865 Normally we prefer signed values, but sticking with ptrdiff_t would
10866 require adding more-complicated checks.
10868 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10869 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
10870 Redo buffer-overflow calculations to avoid integer overflow.
10871 Add a FIXME comment where memory seems to be over-allocated.
10873 * character.c (Fstring): Check for size-calculation overflow.
10875 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
10876 unnecessary integer overflow. Check for size overflow.
10877 (encode_coding_object): Don't update size until xmalloc succeeds.
10879 * composite.c (get_composition_id): Check for overflow in glyph
10880 length calculations.
10882 Integer and memory overflow fixes for display code.
10883 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
10884 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
10885 (scrolling_window): Check for overflow in size calculations.

10890 (scrolling_window): Avoid overflow in size calculations.
10891 Don't update size until allocation succeeds.
10892 * fns.c (concat): Check for overflow in size calculations.
10893 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
10894 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

10897 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
10898 (get_doc_string): Check for size calculation overflow.
10899 Don't update size until allocation succeeds.
10900 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
10901 EMACS_INT, where ptrdiff_t will do.
10902 (Fsubstitute_command_keys): Check for string overflow.
10904 * editfns.c (set_time_zone_rule): Don't assume environment length
10906 (message_length): Now ptrdiff_t, not int.
10907 (Fmessage_box): Don't update size until allocation succeeds.
10908 Don't assume message length fits in int.
10909 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10911 * emacs.c (main): Do not reallocate argv, since there is a null at
10912 the end that can be overwritten, and this way there's no need to
10913 worry about size-calculation overflow.
10914 (sort_args): Check for size-calculation overflow.
10916 * eval.c (init_eval_once, grow_specpdl): Don't update size until
10918 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
10920 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
10921 (x_set_scroll_bar_width, x_figure_window_size):
10922 Check for integer overflow.
10923 (x_set_alpha): Do not assume XINT fits in int.
10925 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10926 This is for the members text_lines, text_cols, total_lines, total_cols,
10927 where the system imposes an 'int' limit.
10929 * fringe.c (Fdefine_fringe_bitmap):
10930 Don't update size until alloc works.
10932 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
10933 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
10935 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
10936 Check for size-calculation overflow.
10937 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10938 do, as we prefer signed integers.
10939 (id_to_widget.max_size, id_to_widget.used)
10940 (xg_store_widget_in_map, xg_remove_widget_from_map)
10941 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
10942 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
10943 Use and return ptrdiff_t, not int.
10944 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
10945 * gtkutil.h: Change prototypes to match the above.
10947 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
10948 are duplicate now that they've been promoted to lisp.h.
10949 (x_allocate_bitmap_record, x_alloc_image_color)
10950 (make_image_cache, cache_image, xpm_load):
10951 Don't update size until alloc is done.

10962 Use ptrdiff_t, not int, to count maps.
10963 (read_char_minibuf_menu_prompt): Check for overflow in size
10964 calculations. Don't update size until allocation succeeds.
10965 Redo calculations to avoid overflow.
10966 * keyboard.h: Change prototypes to match the above.
10968 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
10970 (current_minor_maps): Check for size calculation overflow.
10971 * keymap.h: Change prototypes to match the above.
10973 * lread.c (read1, init_obarray): Don't update size until alloc done.
10975 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

10978 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
10979 Now ptrdiff_t, not int.
10980 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

10992 (Fset_match_data): Don't assume list lengths fit in 'int'.
10994 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
10995 for command line length. Do not attempt to address one before the
10996 beginning of an array, as that's not portable.
10998 * term.c (max_frame_lines): Remove; unused.
10999 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
11001 (encode_terminal_code, calculate_costs): Check for size
11002 calculation overflow.

11008 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
11009 subtracting pointers.
11010 (gobble_line): Check for overflow more carefully. Don't update size
11013 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
11014 Don't update size until alloc done.
11015 Redo size calculations to avoid overflow.
11016 Check for size calculation overflow.

11024 Use ptrdiff_t, not int, for sizes.
11025 (Finternal_make_lisp_face, cache_face):
11026 Check for size calculation overflow.
11027 (cache_face): Treat size calculation overflows as if they were
11028 memory exhaustion (the usual treatment), rather than aborting.
11030 * xfns.c (x_encode_text, x_set_name_internal)
11031 (Fx_change_window_property): Use ptrdiff_t, not int, to count
11032 sizes, since they can exceed INT_MAX in size. Check for size
11033 calculation overflow.
11035 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
11036 (xg_select): Check for size calculation overflow.
11037 Don't update size until alloc done.
11039 * xrdb.c (get_environ_db): Don't assume path length fits in int,
11040 as sprintf is limited to int lengths.
11042 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
11043 (X_LONG_MIN): New macros.
11044 Use them to make the following changes clearer.
11045 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
11046 This change doesn't affect the value now, but it may help remind
11047 future maintainers not to raise the value too much later.
11048 (SELECTION_QUANTUM): Remove, replacing with ...
11049 (selection_quantum): ... new function, which avoids overflow.
11051 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
11052 assumption that selection length fits in 'int'.
11053 (x_reply_selection_request, x_handle_selection_request)
11054 (x_get_window_property, receive_incremental_selection)
11055 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
11056 (lisp_data_to_selection_data, clean_local_selection_data):
11057 Use ptrdiff_t, not int, to record length of selection.
11058 (x_reply_selection_request, x_get_window_property)
11059 (receive_incremental_selection, x_property_data_to_lisp):
11060 Redo calculations to avoid overflow.
11061 (x_reply_selection_request): When sending hint, ceiling it at

11064 (x_get_window_property, receive_incremental_selection)
11065 (lisp_data_to_selection_data, x_property_data_to_lisp):
11066 Check for size-calculation overflow.
11067 (x_get_window_property, receive_incremental_selection)
11068 (lisp_data_to_selection_data, Fx_register_dnd_atom):
11069 Don't store size until memory allocation succeeds.
11070 (x_get_window_property): Plug memory leak on memory exhaustion.
11071 Don't double-block input; malloc is safe here. Don't assume 2**34
11072 - 4 fits in unsigned long. Add an xassert to check
11073 XGetWindowProperty overflow. Be more careful about overflow
11074 calculations, and distinguish size from memory overflow better.
11075 (receive_incremental_selection): When tracing, don't assume
11076 unsigned int is less than INT_MAX.
11077 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
11078 harmful) conversions of unsigned short to int.
11079 (lisp_data_to_selection_data): Don't assume that integers
11080 in the range -65535 through -1 fit in an X unsigned short.
11081 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
11082 result parameters unless successful. Rely on cons_to_unsigned
11083 to report problems with elements; the old code wasn't right anyway.
11084 (x_check_property_data): Check for int overflow; we cannot use
11085 a wider type due to X limits.
11086 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
11088 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

11091 (x_term_init): Check for size calculation overflow.
11092 (x_color_cells): Don't store size until memory allocation succeeds.
11093 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
11094 Don't assume alloca size is less than MAX_ALLOCA.
11095 (x_term_init): Don't assume length fits in int (sprintf is limited
11098 Use ptrdiff_t for composition IDs.

11117 * image.c (xpm_get_color_table_h):
11118 * lisp.h (hash_lookup, hash_put):
11119 * minibuf.c (Ftest_completion):
11120 Use ptrdiff_t for hash table indexes, not int (which is too
11121 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
11122 32-bit --with-wide-int hosts).
11124 * charset.c (Fdefine_charset_internal): Check for integer overflow.
11125 Add a FIXME comment about memory leaks.
11126 (syms_of_charset): Don't assume xmalloc returns.
11128 Don't assume that stated character widths fit in int.
11129 * character.c (Fchar_width, c_string_width, lisp_string_width):
11130 * character.h (CHAR_WIDTH):
11131 * indent.c (MULTIBYTE_BYTES_WIDTH):
11132 Use sanitize_char_width to avoid undefined and/or bad behavior
11133 with outlandish widths.
11134 * character.h (sanitize_tab_width): Rename from sanitize_width,
11135 now that we have two such functions. All uses changed.
11136 (sanitize_char_width): New inline function.
11138 Don't assume that tab-width fits in int.
11139 * character.h (sanitize_width): New inline function.
11140 (SANE_TAB_WIDTH): New macro.
11141 (ASCII_CHAR_WIDTH): Use it.

11146 * fileio.c: Integer overflow issues with file modes.
11147 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
11149 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

11153 * xterm.c: Don't go over XClientMessageEvent limit.
11154 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
11155 (x_send_scroll_bar_event): Likewise. Check that the size does not
11156 exceed limits imposed by XClientMessageEvent, as well as the usual
11157 ptrdiff_t and size_t limits.
11159 * keyboard.c: Overflow, signedness and related fixes.
11160 (make_lispy_movement): Use same integer type in forward decl
11161 that is used in the definition.
11162 (read_key_sequence, keyremap_step):
11163 Change bufsize argument back to int, undoing my 2011-03-30 change.
11164 We prefer signed types, and int is wide enough here.
11165 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
11166 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
11167 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
11168 length, not size_t. Use ptrdiff_t for index, not int.
11169 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
11170 possibility of integer overflow.
11172 Overflow, signedness and related fixes for images.
11174 * dispextern.h (struct it.stack[0].u.image.image_id)
11175 (struct_it.image_id, struct image.id, struct image_cache.size)
11176 (struct image_cache.used, struct image_cache.ref_count):

11182 * xdisp.c (calc_pixel_width_or_height):
11183 * xfns.c (image_cache_refcount):
11184 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
11185 on typical 64-bit hosts.

11193 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
11194 (lookup_image): Remove unnecessary tests.
11195 (xbm_image_p): Locals are now of int, not EMACS_INT,
11196 since parse_image_check makes sure they fit into int.
11197 (png_load, gif_load, svg_load_image):
11198 Prefer int to unsigned where either will do.
11199 (tiff_handler): New function, combining the cores of the
11200 old tiff_error_handler and tiff_warning_handler.
11201 This function is rewritten to use vsnprintf and thereby avoid
11202 stack buffer overflows. It uses only the features of vsnprintf
11203 that are common to both POSIX and native Microsoft.
11204 (tiff_error_handler, tiff_warning_handler): Use it.
11205 (tiff_load, gif_load, imagemagick_load_image):
11206 Don't assume :index value fits in 'int'.
11207 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
11208 (imagemagick_load_image): Check that crop parameters fit into
11209 the integer types that MagickCropImage accepts. Don't assume
11210 Vimagemagick_render_type has a nonnegative value. Don't assume
11211 size_t fits in 'long'.
11212 (gs_load): Use printmax_t to print the widest integers possible.
11213 Check for integer overflow when computing image height and width.

11226 (handle_single_display_spec): If the display spec is of the form
11227 `(space ...)', and specifies display in the text area, return 2
11229 (try_cursor_movement): Check for the need to scroll more
11230 accurately, and prefer exact match for point under bidi.
11231 Don't advance `row' beyond the last row of the window.
11233 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
11234 into disp_prop; all users changed.

11249 buffers, return left-to-right.
11250 (set_cursor_from_row): Consider candidate row a win if its glyph
11251 represents a newline and point is on that newline. Fixes cursor
11252 positioning on the newline at EOL of R2L text within L2R
11253 paragraph, and vice versa.
11254 (try_cursor_movement): Check continued rows, in addition to
11255 continuation rows. Fixes unwarranted scroll when point enters a
11256 continued line of R2L text within an L2R paragraph, or vice versa.
11257 (cursor_row_p): Consider the case of point being equal to
11258 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

11284 * xdisp.c (redisplay_window): When computing centering_position,
11285 account for the height of the header line. (Bug#8874)
11287 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
11288 instead of CHAR_TO_BYTE. Fixes a crash when a completion
11289 candidate is selected by the mouse, and that candidate has a
11290 composed character under the mouse.
11292 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
11293 coordinates reported by pos-visible-in-window-p for a composed
11294 character in column zero.

11304 composed buffer positions.
11306 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
11308 * image.c (gif_load): Don't assume that each subimage has the same
11309 dimensions as the base image. Handle disposal method that is
11310 "undefined" by the gif spec (Bug#9335).

11320 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
11321 from an Org mode buffer to a Speedbar frame.
11323 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
11324 a composition, take its buffer position from IT->cmp_it.charpos.
11325 Fixes cursor positioning at the beginning of a line that begins
11326 with a composed character.
11328 2011-08-18 Eli Zaretskii <eliz@gnu.org>
11330 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
11331 character bidirectional type, use STRONG_L instead. Fixes crashes
11332 in a buffer produced by `describe-categories'.
11334 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
11335 members before the level stack, so they would be saved and
11336 restored when copying iterator state. Fixes incorrect reordering
11337 around TABs covered by display properties.

11474 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
11475 properties. (Bug#9284)

11678 * nsterm.m (ns_draw_text_decoration): New function for drawing
11679 underline, overline, and strike-through.
11680 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
11681 ns_draw_text_decoration. Change treatment of cursor drawing to
11682 accommodate underlining, etc.
11684 2011-07-28 Eli Zaretskii <eliz@gnu.org>
11686 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
11689 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11691 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11692 Without this fix, if a signal arrives just after memory fills up,
11693 'malloc' might be invoked reentrantly.
11695 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11696 In other words, assume that every image size is allowed, on non-X
11697 hosts. This assumption is probably wrong, but it lets Emacs compile.
11699 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11701 * regex.c (re_iswctype): Convert return values to boolean.
11703 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
11705 * xdisp.c (compute_display_string_pos): Don't use cached display
11706 string position if the buffer had its restriction changed.
11709 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11711 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11713 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11715 Integer signedness and overflow and related fixes. (Bug#9079)
11717 * bidi.c: Integer size and overflow fixes.
11718 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
11719 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
11720 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11721 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11722 (bidi_find_other_level_edge):
11723 Use ptrdiff_t instead of EMACS_INT where either will do.
11724 This works better on 32-bit hosts configured --with-wide-int.
11725 (bidi_cache_ensure_space): Check for size-calculation overflow.
11726 Use % rather than repeated addition, for better worst-case speed.
11727 Don't set bidi_cache_size until after xrealloc returns, because it
11729 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11730 (bidi_cache_ensure_space): Also check that the bidi cache size
11731 does not exceed that of the largest Lisp string or buffer. See Eli
11732 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11734 * alloc.c (__malloc_size_t): Remove.
11735 All uses replaced by size_t. See Andreas Schwab's note
11736 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11738 * image.c: Improve checking for integer overflow.
11739 (check_image_size): Assume that f is nonnull, since
11740 it is always nonnull in practice. This is one less thing to
11741 worry about when checking for integer overflow later.
11742 (x_check_image_size): New function, which checks for integer
11743 overflow issues inside X.
11744 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11745 This removes the need for a memory_full check.
11746 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11747 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11748 (xbm_read_bitmap_data): Change locals back to 'int', since
11749 their values must fit in 'int'.
11750 (xpm_load_image, png_load, tiff_load):
11751 Invoke x_create_x_image_and_pixmap earlier,
11752 to avoid much needless work if the image is too large.
11753 (tiff_load): Treat overly large images as if
11754 x_create_x_image_and_pixmap failed, not as malloc failures.
11755 (gs_load): Use x_check_image_size.
11757 * gtkutil.c: Omit integer casts.
11758 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11759 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11761 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11763 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11764 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11765 would wrongly return t on a 64-bit host.
11767 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11768 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11769 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11770 and therefore cause GCC to emit a bogus diagnostic in some cases.
11772 * image.c: Integer signedness and overflow and related fixes.
11773 This is not an exhaustive set of fixes, but it's time to
11774 record what I've got.
11775 (lookup_pixel_color, check_image_size): Remove redundant decls.
11776 (check_image_size): Don't assume that arbitrary EMACS_INT values
11777 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11778 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11779 (tiff_load, imagemagick_load_image):
11780 Check for overflow in size calculations.
11781 (x_create_x_image_and_pixmap): Remove unnecessary test for
11782 xmalloc returning NULL; that can't happen.
11783 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11784 (xpm_color_bucket): Use better integer hashing function.
11785 (xpm_cache_color): Don't possibly over-allocate memory.
11786 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11787 (gif_memory_source):
11788 Use ptrdiff_t, not int or size_t, to record sizes.
11789 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11790 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11791 either works, as we prefer signed integers.
11792 (tiff_read_from_memory, tiff_write_from_memory):
11793 Return tsize_t, not size_t, since that's what the TIFF API wants.
11794 (tiff_read_from_memory): Don't fail simply because the read would
11795 go past EOF; instead, return a short read.
11796 (tiff_load): Omit no-longer-needed casts.
11797 (Fimagemagick_types): Don't assume size fits into 'int'.
11799 Improve hashing quality when configured --with-wide-int.
11800 * fns.c (hash_string): New function, taken from sxhash_string.
11801 Do not discard information about ASCII character case; this
11802 discarding is no longer needed.
11803 (sxhash-string): Use it. Change sig to match it. Caller changed.
11804 * lisp.h: Declare it.
11805 * lread.c (hash_string): Remove, since we now use fns.c's version.
11806 The fns.c version returns a wider integer if --with-wide-int is
11807 specified, so this should help the quality of the hashing a bit.
11809 * emacs.c: Integer overflow minor fix.
11810 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11811 Define only if GNU_LINUX.
11812 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11814 * dispnew.c: Integer signedness and overflow fixes.
11815 Remove unnecessary forward decls, that were a maintenance hassle.
11816 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11818 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11819 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11820 (prepare_desired_row, line_draw_cost):
11821 Use int, not unsigned, where either works.
11822 (save_current_matrix, restore_current_matrix):
11823 Use ptrdiff_t, not size_t, where either works.
11824 (init_display): Check for overflow more accurately, and without
11825 relying on undefined behavior.
11827 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11828 Remove, replacing with the new symbols in lisp.h. All uses changed.
11829 * fileio.c (make_temp_name):
11830 * filelock.c (lock_file_1, lock_file):
11831 * xdisp.c (message_dolog):
11832 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11833 Use pMd etc. instead.
11834 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11835 replacing the pWIDE etc. symbols removed from editfns.c.
11837 * keyboard.h (num_input_events): Now uintmax_t.
11838 This is (very slightly) less likely to mess up due to wraparound.
11841 * buffer.c: Integer signedness fixes.
11842 (alloc_buffer_text, enlarge_buffer_text):
11843 Use ptrdiff_t rather than size_t when either will do, as we prefer
11846 * alloc.c: Integer signedness and overflow fixes.
11847 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11848 (__malloc_size_t): Default to size_t, not to int.
11849 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11850 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11851 Prefer ptrdiff_t to size_t when either would do, as we prefer
11853 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11854 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11855 Now const. Initialize with values that are in range even if char
11857 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11858 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11859 These functions do the right thing with sizes > 2**32.
11860 (check_depth): Now ptrdiff_t, not int.
11861 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11862 Adjust to new way of storing sizes. Check for size overflow bugs
11864 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11865 slightly wrong anyway, as it missed one instance of
11866 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11867 (refill_memory_reserve): Omit needless cast to size_t.
11868 (mark_object_loop_halt): Mark as externally visible.
11870 * xselect.c: Integer signedness and overflow fixes.
11871 (Fx_register_dnd_atom, x_handle_dnd_message):
11872 Use ptrdiff_t, not size_t, since we prefer signed.
11873 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11874 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11875 x_dnd_atoms_size and x_dnd_atoms_length.
11877 * doprnt.c: Prefer signed to unsigned when either works.
11879 * doprnt.c (doprnt):
11881 * xdisp.c (vmessage):
11882 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11883 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11884 prefer signed arithmetic to avoid comparison confusion.
11885 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11886 but is a bit tricky.
11888 Assume freestanding C89 headers, string.h, stdlib.h.
11889 * data.c, doprnt.c, floatfns.c, print.c:
11890 Include float.h unconditionally.
11891 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11892 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11893 * regex.c: Likewise for stddef.h, string.h.
11894 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11895 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11896 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11897 (STDC_HEADERS): Remove obsolete defines.
11898 * sysdep.c: Include limits.h unconditionally.
11900 Assume support for memcmp, memcpy, memmove, memset.
11901 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11902 * regex.c (memcmp, memcpy):
11903 Remove; we assume C89 now.
11905 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11906 (__malloc_safe_bcopy): Remove; no longer needed.
11908 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11909 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11910 well either way, and we prefer signed to unsigned.
11912 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11914 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11915 closes the connection while we're reading (bug#9182).
11917 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11919 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11920 are specified (Bug#9168).
11922 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11924 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11925 Found by GCC static checking and --with-wide-int on a 32-bit host.
11927 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11929 * xdisp.c (compute_display_string_pos): Fix logic of caching
11930 previous display string position. Initialize cached_prev_pos to
11931 -1. Fixes slow-down at the beginning of a buffer.
11933 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11935 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11936 for attrs[LFACE_FONTSET_INDEX].
11938 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11940 * xml.c (parse_region): Remove unused local
11941 that was recently introduced.
11943 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11945 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11946 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11948 * xdisp.c (move_it_in_display_line_to): Record the best matching
11949 position for TO_CHARPOS while scanning the line, and restore it on
11950 exit if none of the characters scanned was an exact match.
11951 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11952 when exact match is impossible due to invisible text, and the
11953 lines are truncated.
11955 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11957 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11960 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11962 Fix a significant slow-down of cursor motion with C-n, C-p,
11963 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11964 auto-repeat under bidi redisplay in fontified buffers.
11965 * xdisp.c (compute_stop_pos_backwards): New function.
11966 (next_element_from_buffer): Call compute_stop_pos_backwards to
11967 find a suitable prev_stop when we find ourselves before
11969 (reseat): Don't look for prev_stop, as that could mean a very long
11971 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11972 <cached_disp_overlay_modiff>: Cache for last found display string
11974 (compute_display_string_pos): Return the cached position if asked
11975 about the same buffer in the same area of character positions, and
11976 the buffer wasn't changed since the time the display string
11977 position was cached.
11979 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11981 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11982 is an integer, which is important for empty lines. (Bug#9149)
11984 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11986 * frame.c (Fmodify_frame_parameters): In tty case, update the
11987 default face if necessary (Bug#4238).
11989 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11991 * editfns.c (Fstring_to_char): No need to explain what a character
11992 is in the docstring (Bug#6576).
11994 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11996 * xml.c (parse_region): Make sure we always return a tree.
11998 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
12000 * xml.c (parse_region): If a document contains only comments,
12003 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12005 * xml.c (make_dom): Return comments, too.
12007 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
12010 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
12011 and the surrounding thread.
12012 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
12013 rather than fgets, and retry after EINTR. Otherwise, 'emacs
12014 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
12016 * s/openbsd.h (BROKEN_SIGIO): Define.
12017 * unexelf.c (unexec) [__OpenBSD__]:
12018 Don't update the .mdebug section of the Alpha COFF symbol table.
12020 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12022 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
12025 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
12027 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
12028 This fixes some race conditions on the permissions of any newly
12031 * alloc.c (valid_pointer_p): Use pipe, not open.
12032 This fixes some permissions issues when debugging.
12034 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
12035 If fchown fails to set both uid and gid, try to set just gid,
12036 as that is sometimes allowed. Adjust the file's mode to eliminate
12037 setuid or setgid bits that are inappropriate if fchown fails.
12039 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
12041 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
12042 to compare Lisp_Objects.
12043 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
12044 global_gnutls_log_level, don't mistake it for a Lisp_Object.
12045 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
12047 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
12049 * lread.c (read_integer): Unread even EOF character.
12050 (read1): Likewise. Properly record start position of symbol.
12052 * lread.c (read1): Read `#:' as empty uninterned symbol if no
12053 symbol character follows.
12055 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
12057 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
12058 This works around a problem with the previous change to Fcopy_file.
12059 Recent glibc declares fchown with __attribute__((warn_unused_result)),
12060 and without this change, GCC might complain about discarding
12061 fchown's return value.
12063 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
12065 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
12067 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
12069 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
12071 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
12073 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
12074 it's used from the C level.
12076 * process.c: Use the same condition for POLL_FOR_INPUT in both
12077 keyboard.c and process.c (bug#1858).
12079 2011-07-09 Lawrence Mitchell <wence@gmx.li>
12081 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
12082 (Fgnutls_boot): Use it.
12084 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
12086 * doc.c (Fsubstitute_command_keys): Revert last change.
12088 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
12090 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
12091 quotes the next character, and doesn't affect other longer
12092 sequences (bug#8935).
12094 * lread.c (syms_of_lread): Clarify that is isn't only
12095 `eval-buffer' and `eval-defun' that's affected by
12096 `lexical-binding' (bug#8460).
12098 2011-07-15 Eli Zaretskii <eliz@gnu.org>
12100 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
12101 bidi redisplay when a line includes both an image and is truncated.
12103 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
12105 Fix minor problems found by static checking.
12106 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
12107 (elsz): Now a signed constant, not a size_t var. We prefer signed
12108 types to unsigned, to avoid integer comparison confusion. Without
12109 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
12110 "cannot optimize loop, the loop counter may overflow", a symptom
12112 * indent.c (Fvertical_motion): Mark locals as initialized.
12113 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
12115 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

12637 (clone_per_buffer_values): Don't assume that

12639 This isn't true in general, and it's particularly not true
12640 if Emacs is configured with --with-wide-int.
12641 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
12642 New macros, used in the buffer.c change.

12678 Random fixes. E.g., (random) never returned negative values.
12679 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
12680 subseconds part to the entropy, as that's a bit more random.
12681 Prefer signed to unsigned, since the signedness doesn't matter and
12682 in general we prefer signed. When given a limit, use a
12683 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12684 latter isn't right if USE_2_TAGS_FOR_INTS.
12685 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12686 not 0..VALMASK. Don't discard "excess" bits that random () returns.

12698 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
12699 This is more efficient than Ffile_directory_p and avoids a minor race.

12703 * buffer.c (Foverlay_put): Say what the return value is
12706 * fileio.c (barf_or_query_if_file_exists): Check first if the file

12710 error be more correct.
12712 * fns.c (Frequire): Remove the mention of the .gz files, since
12713 that's installation-specific, but keep the mention of

12726 Qgnutls_bootprop_verify_error (which is no longer used).
12728 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
12729 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
12730 Also (re)move comments that are misplaced or no longer relevant.
12732 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12734 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

12831 * eval.c (struct backtrace): Simplify and port the data structure.
12832 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12833 signed bit field, as this assumption is not portable and it makes
12834 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12835 "char debug_on_exit : 1" as this is not portable either; instead,
12836 use the portable "unsigned int debug_on_exit : 1". Remove unused
12837 member evalargs. Remove obsolete comments about cc bombing out.
12839 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

12993 * xmenu.c (syms_of_xmenu):
12994 * xsettings.c (syms_of_xsettings):
12995 * xterm.c (syms_of_xterm): Use DEFSYM.
12997 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
12999 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
13001 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
13003 Integer and buffer overflow fixes (Bug#8873).
13005 * print.c (printchar, strout): Check for string overflow.
13006 (PRINTPREPARE, printchar, strout):
13007 Don't set size unless allocation succeeds.
13009 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
13010 for sizes. Check for string overflow more accurately.
13011 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
13013 * macros.c: Integer and buffer overflow fixes.
13014 * keyboard.h (struct keyboard.kbd_macro_bufsize):
13015 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
13016 Use ptrdiff_t, not int, for sizes.
13017 Don't increment bufsize until after realloc succeeds.
13018 Check for size-calculation overflow.
13019 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
13021 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
13023 * lread.c: Integer overflow fixes.
13024 (read_integer): Radix is now EMACS_INT, not int,
13025 to improve quality of diagnostics for out-of-range radices.
13026 Calculate buffer size correctly for out-of-range radices.
13027 (read1): Check for integer overflow in radices, and in
13028 read-circle numbers.
13029 (read_escape): Avoid int overflow.
13030 (Fload, openp, read_buffer_size, read1)
13031 (substitute_object_recurse, read_vector, read_list, map_obarray):
13032 Use ptrdiff_t, not int, for sizes.
13033 (read1): Use EMACS_INT, not int, for sizes.
13034 Check for size overflow.
13036 * image.c (cache_image): Check for size arithmetic overflow.
13038 * lread.c: Integer overflow issues.
13039 (saved_doc_string_size, saved_doc_string_length)
13040 (prev_saved_doc_string_size, prev_saved_doc_string_length):
13041 Now ptrdiff_t, not int.
13042 (read1): Don't assume doc string length fits in int. Check for
13043 out-of-range doc string lengths.
13044 (read_list): Don't assume file position fits in int.
13045 (read_escape): Check for hex character overflow.
13047 2011-06-22 Leo Liu <sdl.web@gmail.com>
13049 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
13050 Move to minibuffer.el.
13052 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13054 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
13055 The following patches are for when GLYPH_DEBUG && !XASSERT.
13056 * dispextern.h (trace_redisplay_p, dump_glyph_string):
13057 * dispnew.c (flush_stdout):
13058 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
13059 Mark as externally visible.
13060 * dispnew.c (check_window_matrix_pointers): Now static.
13061 * dispnew.c (window_to_frame_vpos):
13062 * xfns.c (unwind_create_frame):
13063 * xterm.c (x_check_font): Remove unused local.
13064 * scroll.c (CHECK_BOUNDS):
13065 * xfaces.c (cache_fache): Rename local to avoid shadowing.
13066 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
13067 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
13068 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
13069 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
13071 (debug_method_add): Use va_list and vsprintf rather than relying
13072 on undefined behavior with wrong number of arguments.
13073 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
13074 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
13075 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
13076 since we're not interested in debugging glyphs with old libraries.
13077 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
13078 GCC 4.6.0's static checking.
13080 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13082 Integer overflow and signedness fixes (Bug#8873).

13090 (x_create_bitmap_from_data, x_create_bitmap_from_file)
13091 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
13092 (x_create_bitmap_from_xpm_data):
13093 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
13094 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
13096 * xfaces.c (load_pixmap):
13097 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
13098 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
13099 (.bitmaps_last, struct x_output.icon_bitmap):
13100 Use ptrdiff_t, not int, for bitmap indexes.
13101 (x_allocate_bitmap_record): Check for size overflow.
13102 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
13104 Use ptrdiff_t, not int, for overlay counts.
13105 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
13106 * editfns.c (overlays_around, get_pos_property):
13107 * textprop.c (get_char_property_and_overlay):
13108 * xdisp.c (next_overlay_change, note_mouse_highlight):
13109 * xfaces.c (face_at_buffer_position):
13110 * buffer.c (OVERLAY_COUNT_MAX): New macro.
13111 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
13112 (Fnext_overlay_change, Fprevious_overlay_change)
13113 (mouse_face_overlay_overlaps, Foverlays_in):
13114 Use ptrdiff_t, not int, for sizes.
13115 (overlays_at, overlays_in): Check for size-calculation overflow.
13117 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
13119 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
13120 (x_session_initialize): Do not assume string length fits in int.
13122 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
13123 This is unlikely, but can occur if DPI is outlandish.
13125 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
13126 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
13128 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
13129 * xrdb.c (magic_file_p, search_magic_path):
13130 Omit last arg SUFFIX; it was always 0. All callers changed.
13131 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
13133 * xfont.c (xfont_match): Avoid need for strlen.
13135 * xfns.c: Don't assume strlen fits in int.
13136 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
13138 * xdisp.c (message_log_check_duplicate): Return intmax_t,
13139 not unsigned long, as we prefer signed integers. All callers changed.
13140 Detect integer overflow in repeat count.
13141 (message_dolog): Don't assume print length fits in 39 bytes.
13142 (display_mode_element): Don't assume strlen fits in int.
13144 * termcap.c: Don't assume sizes fit in int and never overflow.
13145 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
13146 (gobble_line): Check for size-calculation overflow.
13148 * minibuf.c (Fread_buffer):
13149 * lread.c (intern, intern_c_string):
13150 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
13151 Don't assume string length fits in int.
13153 * keyboard.c (parse_tool_bar_item):
13154 * gtkutil.c (style_changed_cb): Avoid need for strlen.
13156 * font.c: Don't assume string length fits in int.
13157 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
13158 Use ptrdiff_t, not int.
13159 (font_intern_prop): Don't assume string length fits in int.
13160 Don't assume integer property fits in fixnum.
13161 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
13163 * filelock.c: Fix some buffer overrun and integer overflow issues.
13164 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
13165 Reformulate so as not to need the command string.
13166 Invoke gzip -cd rather than gunzip, as it's more portable.
13167 (lock_info_type, lock_file_1, lock_file):
13168 Don't assume pid_t and time_t fit in unsigned long.
13169 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
13170 (current_lock_owner): Prefer signed type for sizes.
13171 Use memcpy, not strncpy, where memcpy is what is really wanted.
13172 Don't assume (via atoi) that time_t and pid_t fit in int.
13173 Check for time_t and/or pid_t out of range, e.g., via a network share.
13174 Don't alloca where an auto var works fine.
13176 * fileio.c: Fix some integer overflow issues.
13177 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
13178 Don't assume string length fits in int.
13179 (directory_file_name): Don't assume string length fits in long.
13180 (make_temp_name): Don't assume pid fits in int, or that its print
13181 length is less than 20.
13183 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
13185 * coding.c (make_subsidiaries): Don't assume string length fits in int.
13187 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
13189 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
13190 We prefer signed integers, even for size calculations.
13192 * emacs.c: Don't assume string length fits in 'int'.
13193 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
13194 (main): Don't invoke strlen when not needed.
13196 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
13197 (XD_DEBUG_MESSAGE): Don't waste a byte.
13199 * callproc.c (getenv_internal_1, getenv_internal)
13200 (Fgetenv_internal):
13201 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
13203 * lread.c (invalid_syntax): Omit length argument.
13204 All uses changed. This doesn't fix a bug, but it simplifies the
13205 code away from its former Hollerith-constant appearance, and it's
13206 one less 'int' to worry about when looking at integer-overflow issues.
13207 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
13209 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
13210 This didn't break anything, but it didn't help either.
13211 It's confusing to put a bogus integer in a place where the actual
13212 value does not matter.
13213 (LIST_END_P): Remove unused macro and its bogus comment.
13214 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
13216 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
13217 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
13219 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
13220 We prefer signed types, and the value cannot exceed the EMACS_INT
13221 range anyway (because otherwise the length would not be representable).
13222 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
13223 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
13224 This avoids a GCC warning when WIDE_EMACS_INT.
13226 * indent.c (sane_tab_width): New function.
13227 (current_column, scan_for_column, Findent_to, position_indentation)
13228 (compute_motion): Use it. This is just for clarity.
13229 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
13231 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
13233 * lisp.h (lint_assume): New macro.
13234 * composite.c (composition_gstring_put_cache):
13235 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
13237 * editfns.c, insdel.c:
13238 Omit unnecessary forward decls, to simplify future changes.
13240 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
13242 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
13244 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
13245 Use much-faster test for byte-length change.
13246 Don't assume string byte-length fits in 'int'.
13247 Check that character arg fits in 'int'.
13248 (mapcar1): Declare byte as byte, for clarity.
13250 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
13252 * fns.c (concat): Catch string overflow earlier.
13253 Do not rely on integer wraparound.
13255 * dispextern.h (struct it.overlay_strings_charpos)
13256 (struct it.selective): Now EMACS_INT, not int.
13257 * xdisp.c (forward_to_next_line_start)
13258 (back_to_previous_visible_line_start)
13259 (reseat_at_next_visible_line_start, next_element_from_buffer):
13260 Don't arbitrarily truncate the value of 'selective' to int.
13262 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
13264 * composite.c: Don't truncate sizes to 'int'.
13265 (composition_gstring_p, composition_reseat_it)
13266 (composition_adjust_point): Use EMACS_INT, not int.
13267 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
13268 not EMACS_UINT, for indexes.
13270 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
13272 * buffer.c: Include <verify.h>.
13273 (struct sortvec.priority, struct sortstr.priority):
13274 Now EMACS_INT, not int.
13275 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
13276 (struct sortstr.size, record_overlay_string)
13277 (struct sortstrlist.size, struct sortlist.used):
13278 Don't truncate size to int.
13279 (record_overlay_string): Check for size-calculation overflow.
13280 (init_buffer_once): Check at compile-time, not run-time.
13282 2011-06-22 Jim Meyering <meyering@redhat.com>
13284 Don't leak an XBM-image-sized buffer
13285 * image.c (xbm_load): Free the image buffer after using it.
13287 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
13290 * composite.c (find_automatic_composition): Omit needless 'return 0;'
13291 that Sun C diagnosed.
13292 * fns.c (secure_hash): Fix pointer signedness issue.
13293 * intervals.c (static_offset_intervals): New function.
13294 (offset_intervals): Use it.
13296 2011-06-21 Leo Liu <sdl.web@gmail.com>
13299 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
13302 * fns.c (secure_hash): Rename from crypto_hash_function and change
13303 the first arg to accept symbols.
13304 (Fsecure_hash): New primitive.
13305 (syms_of_fns): New symbols.
13307 2011-06-20 Deniz Dogan <deniz@dogan.se>
13309 * process.c (Fset_process_buffer): Clarify return value in
13312 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
13314 * dispnew.c (add_window_display_history): Use BVAR.
13316 * xdisp.c (debug_method_add): Use BVAR.
13317 (check_window_end, dump_glyph_matrix, dump_glyph)
13318 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
13320 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
13323 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
13324 check till after the cache is created in init_frame_faces.
13326 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
13328 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
13330 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
13332 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
13333 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
13334 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
13336 Improve buffer-overflow checking (Bug#8873).
13337 * fileio.c (Finsert_file_contents):
13338 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
13339 Remove the old (too-loose) buffer overflow checks.
13340 They weren't needed, since make_gap checks for buffer overflow.
13341 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
13342 The old code merely checked for Emacs fixnum overflow, and relied
13343 on undefined (wraparound) behavior. The new code avoids undefined
13344 behavior, and also checks for ptrdiff_t and/or size_t overflow.
13346 * editfns.c (Finsert_char): Don't dump core with very negative counts.
13347 Tune. Don't use wider integers than needed. Don't use alloca.
13348 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
13350 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
13352 * insdel.c, lisp.h (buffer_overflow): New function.
13353 (insert_from_buffer_1, replace_range, replace_range_2):
13354 * insdel.c (make_gap_larger):
13355 * editfns.c (Finsert_char):
13356 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
13358 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
13360 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
13362 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
13364 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
13365 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
13367 * fileio.c: Don't assume EMACS_INT fits in off_t.
13368 (emacs_lseek): New static function.
13369 (Finsert_file_contents, Fwrite_region): Use it.
13370 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
13372 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
13374 * fns.c: Don't overflow int when computing a list length.
13375 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
13376 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
13377 truncation on 64-bit hosts. Check for QUIT every
13378 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
13379 faster and is responsive enough.
13380 (Flength): Report an error instead of overflowing an integer.
13381 (Fsafe_length): Return a float if the value is not representable
13382 as a fixnum. This shouldn't happen except in contrived situations.
13383 (Fnthcdr, Fsort): Don't assume list length fits in int.
13384 (Fcopy_sequence): Don't assume vector length fits in int.
13386 * alloc.c: Check that resized vectors' lengths fit in fixnums.
13387 (header_size, word_size): New constants.
13388 (allocate_vectorlike): Don't check size overflow here.
13389 (allocate_vector): Check it here instead, since this is the only
13390 caller of allocate_vectorlike that could cause overflow.
13391 Check that the new vector's length is representable as a fixnum.
13393 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
13394 The previous code was bogus. For example, next_almost_prime (32)
13395 returned 39, which is undesirable as it is a multiple of 3; and
13396 next_almost_prime (24) returned 25, which is a multiple of 5 so
13397 why was the code bothering to check for multiples of 7?
13399 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
13401 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
13403 Variadic C functions now count arguments with ptrdiff_t.
13404 This partly undoes my 2011-03-30 change, which replaced int with size_t.
13405 Back then I didn't know that the Emacs coding style prefers signed int.
13406 Also, in the meantime I found a few more instances where arguments
13407 were being counted with int, which may truncate counts on 64-bit
13408 machines, or EMACS_INT, which may be unnecessarily wide.
13409 * lisp.h (struct Lisp_Subr.function.aMANY)
13410 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
13411 Arg counts are now ptrdiff_t, not size_t.
13412 All variadic functions and their callers changed accordingly.
13413 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
13414 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
13415 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
13416 * callint.c (Fcall_interactively): Check arg count for overflow,
13417 to avoid potential buffer overrun. Use signed char, not 'int',
13418 for 'varies' array, so that we needn't bother to check its size
13419 calculation for overflow.
13420 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
13421 * eval.c (apply_lambda):
13422 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
13423 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
13424 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
13426 * callint.c (Fcall_interactively): Don't use index var as event count.
13428 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
13429 * mem-limits.h (SIZE): Remove; no longer used.
13431 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
13433 Remove unnecessary casts.
13434 * xterm.c (x_term_init):
13435 * xfns.c (x_set_border_pixel):
13436 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
13437 These aren't needed now that we assume ANSI C.
13439 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
13440 It's more likely to cause problems (due to unsigned overflow)
13443 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
13445 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
13447 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
13449 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
13451 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
13453 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
13455 GLYPH_CODE_FACE returns EMACS_INT, not int.
13456 * dispextern.h (merge_faces):
13457 * xfaces.c (merge_faces):
13458 * xdisp.c (get_next_display_element, next_element_from_display_vector):
13459 Don't assume EMACS_INT fits in int.
13461 * character.h (CHAR_VALID_P): Remove unused parameter.
13462 * fontset.c, lisp.h, xdisp.c: All uses changed.
13464 * editfns.c (Ftranslate_region_internal): Omit redundant test.
13466 * fns.c (concat): Minor tuning based on overflow analysis.
13467 This doesn't fix any bugs. Use int to hold character, instead
13468 of constantly refetching from Emacs object. Use XFASTINT, not
13469 XINT, for value known to be a character. Don't bother comparing
13470 a single byte to 0400, as it's always less.
13472 * floatfns.c (Fexpt):
13473 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
13475 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
13478 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
13480 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
13481 Without this fix, on a 64-bit host (aset S 0 4294967386) would
13482 incorrectly succeed when S was a string, because 4294967386 was
13483 truncated before it was used.
13485 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13486 Otherwise, an out-of-range integer could cause undefined behavior
13489 * composite.c: Use int, not EMACS_INT, for characters.
13490 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13491 EMACS_INT, for values that are known to be in character range.
13492 This doesn't fix any bugs but is the usual style inside Emacs and
13493 may generate better code on 32-bit machines.
13495 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13496 This is for reasons similar to the recent CHAR_STRING fix.
13497 * charset.c (Fencode_char): Check that character arg is actually
13498 a character. Pass an int to ENCODE_CHAR.
13499 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13500 wider than 'int', as a compile-time check to prevent future regressions
13503 * character.c (char_string): Remove unnecessary casts.
13505 Make sure a 64-bit char is never passed to CHAR_STRING.
13506 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13507 by silently ignoring the top 32 bits, allowing some values
13508 that were far too large to be valid characters.
13509 * character.h: Include <verify.h>.
13510 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13511 arguments are no wider than unsigned, as a compile-time check
13512 to prevent future regressions in this area.
13514 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
13515 (Fsubst_char_in_region):
13517 * xdisp.c (decode_mode_spec_coding):
13518 Adjust to CHAR_STRING's new requirement.
13519 * editfns.c (Finsert_char, Fsubst_char_in_region):
13520 * fns.c (concat): Check that character args are actually
13521 characters. Without this test, these functions did the wrong
13522 thing with wildly out-of-range values on 64-bit hosts.
13524 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13525 These casts should not be needed on 32-bit hosts, either.
13526 * keyboard.c (read_char):
13527 * lread.c (Fload): Remove casts to unsigned.
13529 * lisp.h (UNSIGNED_CMP): New macro.
13530 This fixes comparison bugs on 64-bit hosts.
13531 (ASCII_CHAR_P): Use it.
13532 * casefiddle.c (casify_object):
13533 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
13534 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
13535 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
13536 * dispextern.h (FACE_FROM_ID):
13537 * keyboard.c (read_char): Use UNSIGNED_CMP.
13539 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
13540 not to EMACS_INT, to avoid GCC warning.
13542 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13544 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13545 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
13546 isn't needed on 32-bit machines.
13548 * buffer.c (Fgenerate_new_buffer_name):
13549 Use EMACS_INT for count, not int.
13550 (advance_to_char_boundary): Return EMACS_INT, not int.
13552 * data.c (Qcompiled_function): Now static.
13554 * window.c (window_body_lines): Now static.
13556 * image.c (gif_load): Rename local to avoid shadowing.
13558 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
13559 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
13560 * alloc.c (make_save_value): Integer argument is now of type
13561 ptrdiff_t, not int.
13562 (mark_object): Use ptrdiff_t, not int.
13563 * lisp.h (pD): New macro.
13564 * print.c (print_object): Use it.
13566 * alloc.c: Use EMACS_INT, not int, to count objects.
13567 (total_conses, total_markers, total_symbols, total_vector_size)
13568 (total_free_conses, total_free_markers, total_free_symbols)
13569 (total_free_floats, total_floats, total_free_intervals)
13570 (total_intervals, total_strings, total_free_strings):
13571 Now EMACS_INT, not int. All uses changed.
13572 (Fgarbage_collect): Compute overall total using a double, so that
13573 integer overflow is less likely to be a problem. Check for overflow
13574 when converting back to an integer.
13575 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
13576 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
13577 These were 'int' variables that could overflow on 64-bit hosts;
13578 they were never used, so remove them instead of repairing them.
13579 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
13580 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
13581 Previously, this ceilinged at INT_MAX, but that doesn't work on
13583 (allocate_pseudovector): Don't use EMACS_INT when int would do.
13585 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
13586 (allocate_vectorlike): Check for ptrdiff_t overflow.
13587 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13588 when a (possibly-narrower) signed value would do just as well.
13589 We prefer using signed arithmetic, to avoid comparison confusion.
13591 * alloc.c: Catch some string size overflows that we were missing.
13592 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
13593 for convenience in STRING_BYTES_MAX.
13594 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
13595 The definition here is exact; the one in lisp.h was approximate.
13596 (allocate_string_data): Check for string overflow. This catches
13597 some instances we weren't catching before. Also, it catches
13598 size_t overflow on (unusual) hosts where SIZE_MAX <= min
13599 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
13600 and ptrdiff_t and EMACS_INT are both 64 bits.
13602 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
13603 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
13604 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
13606 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
13608 * alloc.c (Fmake_string): Check for out-of-range init.
13610 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
13612 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
13614 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
13616 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

13619 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
13620 (int_gtk_range_get_value): Move to the scroll bar part of the file.
13621 (style_changed_cb): Call update_theme_scrollbar_width and call

13627 and height if HAVE_GTK3 (Bug#8505).
13628 (scroll_bar_width_for_theme): New variable.
13629 (update_theme_scrollbar_width): New function.
13630 (xg_get_default_scrollbar_width): Move code to
13631 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
13632 (xg_initialize): Call update_theme_scrollbar_width.
13634 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
13636 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
13638 2011-06-12 Martin Rudalics <rudalics@gmx.at>
13640 * frame.c (make_frame): Call other_buffer_safely instead of
13643 * window.c (temp_output_buffer_show): Call display_buffer with
13644 second argument Vtemp_buffer_show_specifiers and reset latter
13645 immediately after the call.
13646 (Vtemp_buffer_show_specifiers): New variable.
13647 (auto_window_vscroll_p, next_screen_context_lines)
13648 (Vscroll_preserve_screen_position): Remove leading asterisks from

13671 wasn't returning anything.
13672 (compare_window_configurations): Remove unused locals.
13673 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.

13694 (Fset_window_configuration): Rewrite to handle dead buffers and
13695 consequently deletable windows.
13696 (window_tree, Fwindow_tree): Remove. Supply functionality in

13831 Remove static from declaration of Qdelete_window, it's
13832 temporarily needed by Fbury_buffer.
13833 (replace_window): Don't assign orig_top_line and
13835 (Fdelete_window, delete_window): Remove. Window deletion is

13837 (window_loop): Remove DELETE_OTHER_WINDOWS case.
13838 Replace Fdelete_window calls with calls to Qdelete_window.
13839 (Fdelete_other_windows): Remove. Deleting other windows is

14212 value of a `display' property is a "replacing spec".
14213 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
14214 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

14244 * gnutls.c: Use Emacs's memory allocators.
14245 Without this change, the gnutls library would invoke malloc etc.
14246 directly, which causes problems on non-SYNC_INPUT hosts, and which
14247 runs afoul of improving memory_full behavior. (Bug#8761)
14248 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
14249 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
14250 xfree instead of the default malloc, realloc, free.
14251 (Fgnutls_boot): No need to check for memory allocation failure,
14252 since xmalloc does that for us.

14281 need to be updated by these changes.
14282 * fns.c (make_hash_table, maybe_resize_hash_table):
14283 Check for integer overflow with large hash tables.
14284 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
14285 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
14286 (SXHASH_REDUCE): New macro.

14290 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
14291 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
14292 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
14293 Rewrite to use FIXNUM_BITS, as this simplifies things.
14294 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
14295 Adjust signatures to match updated version of code.
14296 (consing_since_gc): Now EMACS_INT, since a single hash table can
14297 use more than INT_MAX bytes.
14299 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
14301 Make it possible to build with GCC-4.6+ -O2 -flto.
14303 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
14305 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
14307 * minibuf.c (get_minibuffer, read_minibuf_unwind):
14308 Call minibuffer-inactive-mode.
14310 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
14312 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
14313 Update dependencies.
14315 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14317 * data.c (init_data): Remove code for UTS, this system is not
14320 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14322 Don't force ./temacs to start in terminal mode.
14324 * frame.c (make_initial_frame): Initialize faces in all cases, not
14325 only when CANNOT_DUMP is defined.
14326 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
14328 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14330 * dispnew.c (add_window_display_history): Use const for the string
14331 pointer. Remove declaration, not needed.
14333 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14335 Use 'inline', not 'INLINE'.
14336 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
14337 * alloc.c, fontset.c (INLINE): Remove.
14338 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
14339 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
14340 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
14341 * gmalloc.c (register_heapinfo): Use inline unconditionally.
14342 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
14344 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14346 Make it possible to run ./temacs.
14348 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
14349 syms_of_callproc does the same thing. Remove test for
14350 "initialized", do it in the caller.
14351 * emacs.c (main): Avoid calling set_initial_environment when dumping.
14353 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
14355 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
14356 (read_minibuf): Use get_minibuffer.
14357 (syms_of_minibuf): Use DEFSYM.
14358 (Qmetadata): New var.
14359 * data.c (Qbuffer): Don't make it static.
14360 (syms_of_data): Use DEFSYM.
14362 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14364 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
14365 (CCL_CODE_MIN): New macro.
14367 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
14369 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
14371 * eval.c (Qdebug): Now static.
14372 * lisp.h (Qdebug): Remove decl. This reverts a part of the
14373 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
14374 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
14376 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14378 * image.c: Various fixes to ImageMagick code comments.
14379 (Fimagemagick_types): Doc fix.
14381 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
14383 Minor fixes prompted by GCC 4.6.0 warnings.
14385 * xselect.c (converted_selections, conversion_fail_tag): Now static.
14387 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
14388 (x_clipboard_manager_save_all): Move extern decl to ...
14389 * xterm.h: ... here, so that it can be checked for consistency.
14391 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14393 * xselect.c (x_clipboard_manager_save_frame)
14394 (x_clipboard_manager_save_all): New functions.
14395 (Fx_clipboard_manager_save): Lisp function deleted.
14397 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
14398 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
14400 * xterm.h: Update prototype.
14402 2011-05-28 William Xu <william.xwl@gmail.com>
14404 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
14405 exiting (Bug#8239).
14407 2011-05-28 Jim Meyering <meyering@redhat.com>
14409 Avoid a sign-extension bug in crypto_hash_function.
14410 * fns.c (to_uchar): Define.
14411 (crypto_hash_function): Use it to convert some newly-signed
14412 variables to unsigned, to avoid sign-extension bugs. For example,
14413 without this change, (md5 "truc") would evaluate to
14414 45723a2aff78ff4fff7fff1114760e62 rather than the expected
14415 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
14416 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
14418 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14420 Integer overflow fixes.
14422 * dbusbind.c: Serial number integer overflow fixes.
14423 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
14424 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
14425 to hold a serial number that is too large for a fixnum.
14426 (Fdbus_method_return_internal, Fdbus_method_error_internal):
14427 Check for serial numbers out of range. Decode any serial number
14428 that was so large that it became a float. (Bug#8722)
14430 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
14431 (Fdbus_call_method, Fdbus_call_method_asynchronously):
14432 Use XFASTINT rather than XUINT when numbers are nonnegative.
14433 (xd_append_arg, Fdbus_method_return_internal):
14434 (Fdbus_method_error_internal): Likewise. Also, for unsigned
14435 arguments, check that Lisp number is nonnegative, rather than
14436 silently wrapping negative numbers around. (Bug#8722)
14437 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
14440 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
14442 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
14444 ccl: Add integer overflow checks.
14445 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
14446 (IN_INT_RANGE): New macros.
14447 (ccl_driver): Use them to check for integer overflow when
14448 decoding a CCL program. Many of the new checks are whether XINT (x)
14449 fits in int; it doesn't always, on 64-bit hosts. The new version
14450 doesn't catch all possible integer overflows, but it's an
14451 improvement. (Bug#8719)
14453 * alloc.c (make_event_array): Use XINT, not XUINT.
14454 There's no need for unsigned here.
14456 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
14457 This follows up to the 2011-05-06 change that substituted uintptr_t
14458 for EMACS_INT. This case wasn't caught back then.
14460 Rework Fformat to avoid integer overflow issues.
14461 * editfns.c: Include <float.h> unconditionally, as it's everywhere
14462 now (part of C89). Include <verify.h>.
14463 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
14464 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
14465 (Fformat): Avoid the prepass trying to compute sizes; it was only
14466 approximate and thus did not catch overflow reliably. Instead, walk
14467 through the format just once, formatting and computing sizes as we go,
14468 checking for integer overflow at every step, and allocating a larger
14469 buffer as needed. Keep track separately whether the format is
14470 multibyte. Keep only the most-recently calculated precision, rather
14471 than them all. Record whether each argument has been converted to
14472 string. Use EMACS_INT, not int, for byte and char and arg counts.
14473 Support field widths and precisions larger than INT_MAX. Avoid
14474 sprintf's undefined behavior with conversion specifications such as %#d
14475 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
14476 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
14477 formatting out-of-range floating point numbers with int
14478 formats. (Bug#8668)
14480 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
14482 * data.c: Avoid integer truncation in expressions involving floats.
14483 * data.c: Include <intprops.h>.
14484 (arith_driver): When there's an integer overflow in an expression
14485 involving floating point, convert the integers to floating point
14486 so that the resulting value does not suffer from catastrophic
14487 integer truncation. For example, on a 64-bit host (* 4
14488 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14489 Do not rely on undefined behavior after integer overflow.
14491 merge count_size_as_multibyte, parse_str_to_multibyte
14492 * character.c, character.h (count_size_as_multibyte):
14493 Rename from parse_str_to_multibyte; all uses changed.
14494 Check for integer overflow.
14495 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14496 since it's now a duplicate of the other. This is more of
14497 a character than a buffer op, so better that it's in character.c.
14498 * fns.c, print.c: Adjust to above changes.
14500 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14502 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14504 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14506 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14507 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14508 (x_clipboard_manager_save): Now static.
14509 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14511 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14512 (crypto_hash_function): Now static.
14513 Fix pointer signedness problems. Avoid unnecessary initializations.
14515 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14517 * termhooks.h (Vselection_alist): Make it terminal-local.
14519 * terminal.c (create_terminal): Initialize it.
14521 * xselect.c: Support for clipboard managers.
14522 (Vselection_alist): Move to termhooks.h as terminal-local var.
14523 (LOCAL_SELECTION): New macro.
14524 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14525 (symbol_to_x_atom): Remove gratuitous arg.
14526 (x_handle_selection_request, lisp_data_to_selection_data)
14527 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14528 (x_own_selection, x_get_local_selection, x_convert_selection):
14529 New arg, specifying work frame. Use terminal-local Vselection_alist.
14530 (some_frame_on_display): Delete unused function.
14531 (Fx_own_selection_internal, Fx_get_selection_internal)
14532 (Fx_disown_selection_internal, Fx_selection_owner_p)
14533 (Fx_selection_exists_p): New optional frame arg.
14534 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14535 (x_handle_selection_clear): Don't treat other terminals with the
14536 same keyboard specially. Use the terminal-local Vselection_alist.
14537 (x_clear_frame_selections): Use Frun_hook_with_args.
14539 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14541 * xterm.h: Add support for those atoms.
14543 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14545 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14546 (converted_selections, conversion_fail_tag): New global variables.
14547 (x_selection_request_lisp_error): Free the above.
14548 (x_get_local_selection): Remove unnecessary code.
14549 (x_reply_selection_request): Args changed; handle arbitrary array
14550 of converted selections stored in converted_selections.
14551 Separate the XChangeProperty and SelectionNotify steps.
14552 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14553 (x_convert_selection): New function.
14554 (x_handle_selection_event): Simplify.
14555 (x_get_foreign_selection): Don't ignore incoming requests while
14556 waiting for an answer; this will fail when we implement
14557 SAVE_TARGETS, and seems unnecessary anyway.
14558 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14559 (Vx_sent_selection_functions): Doc fix.
14561 2011-05-26 Leo Liu <sdl.web@gmail.com>
14563 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14565 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14567 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14569 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14570 for fringe update if it has periodic bitmap.
14571 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14572 and fringe_bitmap_periodic_p.
14574 * fringe.c (get_fringe_bitmap_data): New function.
14575 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14576 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14577 row. Mark glyph row for fringe update if periodicity changed.
14579 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14580 for fringe update unless it has periodic bitmap.
14582 2011-05-25 Kenichi Handa <handa@m17n.org>
14584 * xdisp.c (get_next_display_element): Set correct it->face_id for
14585 a static composition.
14587 2011-05-24 Leo Liu <sdl.web@gmail.com>
14590 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
14592 * fns.c (crypto_hash_function, Fsha1): New function.
14593 (Fmd5): Use crypto_hash_function.
14594 (syms_of_fns): Add Ssha1.
14596 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14598 * gnutls.c: Remove unused macros.
14599 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14600 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14601 Remove macros that are defined and never used.
14602 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14604 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14606 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14607 (Fx_get_selection_internal): Minor cleanup.
14608 (Fx_own_selection_internal): Rename arguments for consistency with
14611 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14613 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
14615 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14617 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
14619 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14621 * dispnew.c (scrolling_window): Don't exclude the case that the
14622 last enabled row in the desired matrix touches the bottom boundary.
14624 2011-05-21 Glenn Morris <rgm@gnu.org>
14626 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
14627 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
14628 and add some more files.
14630 2011-05-20 Eli Zaretskii <eliz@gnu.org>
14632 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
14633 report_file_error introduced by the change from 2011-05-07.
14635 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14637 * systime.h (Time): Define only if emacs is defined.
14638 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14639 where the include path doesn't have X11/X.h by default. See
14640 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14642 2011-05-20 Kenichi Handa <handa@m17n.org>
14644 * composite.c (find_automatic_composition): Fix previous change.
14646 2011-05-20 Glenn Morris <rgm@gnu.org>
14648 * lisp.mk: New file, split from Makefile.in.
14649 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14650 (shortlisp): Remove.
14651 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14653 2011-05-19 Glenn Morris <rgm@gnu.org>
14655 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14656 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14657 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14658 (lisp): Set the order to that of loadup.el.
14659 (shortlisp): Make it a copy of $lisp.
14660 (SOME_MACHINE_LISP): Remove.
14661 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14662 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14664 2011-05-18 Kenichi Handa <handa@m17n.org>
14666 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14667 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14668 (find_automatic_composition): Mostly rewrite for efficiency.
14670 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14672 * makefile.w32-in: Update dependencies.
14674 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14676 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14677 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14679 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14681 Fix some integer overflow issues, such as string length overflow.
14683 * insdel.c (count_size_as_multibyte): Check for string overflow.
14685 * character.c (lisp_string_width): Check for string overflow.
14686 Use EMACS_INT, not int, for string indexes and lengths; in
14687 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14688 the resulting string length overflows an EMACS_INT; instead,
14689 report a string overflow if no precision given. When checking for
14690 precision exhaustion, use a check that cannot possibly have
14691 integer overflow. (Bug#8675)
14692 * character.h (lisp_string_width): Adjust to new signature.
14694 * alloc.c (string_overflow): New function.
14695 (Fmake_string): Use it. This doesn't change behavior, but saves
14696 a few bytes and will simplify future changes.
14697 * character.c (string_escape_byte8): Likewise.
14698 * lisp.h (string_overflow): New decl.
14700 Fixups, following up to the user-interface timestamp change.
14701 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14702 for UI timestamps, instead of unsigned long.
14703 * msdos.c (mouse_get_pos): Likewise.
14704 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14705 * w32gui.h (Time): Define by including "systime.h" rather than by
14706 declaring it ourselves. (Bug#8664)
14708 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14709 * image.c (clear_image_cache): Likewise.
14711 * term.c (term_mouse_position): Don't assume time_t wraparound.
14713 Be more systematic about user-interface timestamps.
14714 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14715 and sometimes 'EMACS_UINT', to represent these timestamps.
14716 This change causes it to use 'Time' uniformly, as that's what X uses.
14717 This makes the code easier to follow, and makes it easier to catch
14718 integer overflow bugs such as Bug#8664.
14719 * frame.c (Fmouse_position, Fmouse_pixel_position):
14720 Use Time, not unsigned long, for user-interface timestamps.
14721 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14722 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14723 * keyboard.h (last_event_timestamp): Likewise.
14724 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14725 * menu.h (xmenu_show): Likewise.
14726 * term.c (term_mouse_position): Likewise.
14727 * termhooks.h (struct input_event.timestamp): Likewise.
14728 (struct terminal.mouse_position_hook): Likewise.
14729 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14730 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14731 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14732 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14733 what it was before.
14734 * menu.h, termhooks.h: Include "systime.h", for Time.
14736 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14737 Don't assume that the difference between two unsigned long values
14738 can fit into an integer. At this point, we know button_down_time
14739 <= event->timestamp, so the difference must be nonnegative, so
14740 there's no need to cast the result if double-click-time is
14741 nonnegative, as it should be; check that it's nonnegative, just in
14742 case. This bug is triggered when events are more than 2**31 ms
14743 apart (about 25 days). (Bug#8664)
14745 * xselect.c (last_event_timestamp): Remove duplicate decl.
14746 (x_own_selection): Remove needless cast to unsigned long.
14748 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14749 that always fit in int. Use a sentinel instead of a counter, to
14750 avoid a temp and to allay GCC's concerns about possible int overflow.
14751 * frame.h (struct frame): Use int for menu_bar_items_used
14752 instead of EMACS_INT, since it always fits in int.
14754 * menu.c (grow_menu_items): Check for int overflow.
14756 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14758 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14759 Before, the code was not consistent. These values cannot exceed
14760 2**31 - 1 so there's no need to make them unsigned.
14761 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14762 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14763 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14765 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14767 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14768 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14769 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14770 presumably because the widths might not match.
14772 * window.c (size_window): Avoid needless test at loop start.
14774 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14776 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14778 2011-05-12 Drew Adams <drew.adams@oracle.com>
14780 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14782 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14784 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14785 `width' to `bar_area_x' and `bar_area_width', respectively.
14786 (x_scroll_run): Take account of fringe background extension.
14788 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14789 Rename local vars `left' and `width' to `bar_area_x' and
14790 `bar_area_width', respectively.
14791 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14792 background extension.
14794 2011-05-10 Jim Meyering <meyering@redhat.com>
14796 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14798 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14800 * image.c (Finit_image_library): Return t for built-in image types,
14801 like pbm and xbm. (Bug#8640)
14803 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14805 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14807 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14809 * w32console.c (Fset_screen_color): Doc fix.
14810 (Fget_screen_color): New function.
14811 (syms_of_ntterm): Defsubr it.
14813 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14814 unlink the temporary file if Fcall_process didn't create it in the
14816 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14817 child process will be redirected to a file specified with `:file'.
14818 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14819 cue to call_process_cleanup not to close that handle.
14821 2011-05-07 Ben Key <bkey76@gmail.com>
14823 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14824 one of two shell specific rules, either bootstrap-temacs-CMD or
14825 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14826 to the previous implementation of the bootstrap-temacs rule.
14827 The bootstrap-temacs-CMD rule is similar to the previous
14828 implementation of the bootstrap-temacs rule except that it
14829 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14832 These changes, along with some changes to nt/configure.bat,
14833 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14834 earlier fix to add support for --cflags and --ldflags options
14835 that include quotes so that it works whether make uses cmd or
14838 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14840 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14841 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14843 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14844 a string. Handle both cases.
14845 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14846 (Fdbus_register_method): Use Qinvalid_function.
14848 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14850 * makefile.w32-in: Update dependencies.
14851 (LISP_H): Add inttypes.h and stdin.h.
14852 (PROCESS_H): Add unistd.h.
14854 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14856 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14857 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14859 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14861 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14863 * term.c (vfatal): Remove stray call to va_end.
14864 It's not needed and the C Standard doesn't allow it here anyway.
14866 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14867 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14869 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14872 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14874 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14876 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14878 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14880 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14882 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14883 * charset.c (Fdefine_charset_internal): Don't initialize
14884 charset.code_space[15]. The value was garbage, on hosts with
14885 32-bit int (Bug#8600).
14887 * lread.c (read_integer): Be more consistent with string-to-number.
14888 Use string_to_number to do the actual conversion; this avoids
14889 rounding errors and fixes some other screwups. Without this fix,
14890 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14891 (digit_to_number): Move earlier, for benefit of read_integer.
14892 Return -1 if the digit is out of range for the base, -2 if it is
14893 not a digit in any supported base. (Bug#8602)
14895 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14897 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14898 to match comment at start of function. This also removes a
14899 GCC warning about overflow in a 32+64-bit port.
14901 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14903 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14904 Reported by Stefan Monnier in
14905 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14906 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14907 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14909 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14910 (EMACS_UINTPTR): Likewise, with uintptr_t.
14912 * lisp.h: Prefer 64-bit EMACS_INT if available.
14913 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14914 on 32-bit hosts that have 64-bit int, so that they can access
14916 However, temporarily disable this change unless the temporary
14917 symbol WIDE_EMACS_INT is defined.
14919 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14921 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14922 This removes an assumption that EMACS_INT and long are the same
14923 width as pointers. The assumption is true for Emacs porting targets
14924 now, but we want to make other targets possible.
14925 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14926 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14927 In the rest of the code, change types of integers that hold casted
14928 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14929 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14930 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14931 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14932 No need to cast type when ORing.
14933 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14934 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14935 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14936 assume EMACS_INT is the same width as char *.
14937 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14938 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14939 Remove no-longer-needed casts.
14940 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14941 (xg_tool_bar_help_callback, xg_make_tool_item):
14942 Use EMACS_INTPTR to hold an integer
14943 that will be cast to void *; this can avoid a GCC warning
14944 if EMACS_INT is not the same width as void *.
14945 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14946 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14947 (current_message_1, set_message_1):
14948 Use a local to convert to proper width without a cast.
14949 * xmenu.c (dialog_selection_callback): Likewise.
14951 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14952 Also, don't assume VALBITS / RAND_BITS is less than 5,
14953 and don't rely on undefined behavior when shifting a 1 left into
14955 * lisp.h (get_random): Change signature to match.
14957 * lread.c (hash_string): Use size_t, not int, for hash computation.
14958 Normally we prefer signed values; but hashing is special, because
14959 it's better to use unsigned division on hash table sizes so that
14960 the remainder is nonnegative. Also, size_t is the natural width
14961 for hashing into memory. The previous code used 'int', which doesn't
14962 retain enough info to hash well into very large tables.
14963 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14965 * dbusbind.c: Don't possibly lose pointer info when converting.
14966 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14967 Use XPNTR rather than XHASH, so that the high-order bits of
14968 the pointer aren't lost when converting through void *.
14970 * eval.c (Fautoload): Don't double-shift a pointer.
14972 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14974 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14976 * gnutls.c (DEF_GNUTLS_FN):
14977 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14979 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14981 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14984 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14986 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14987 New version that can reserve upto 2GB of heap space.
14989 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14991 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14993 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14995 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14996 `gnutls_certificate_set_x509_key_file'.
14998 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
15000 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
15001 Update dependencies.
15003 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15005 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
15006 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
15007 Remove unused parameter `fildes'.
15008 * process.c (read_process_output, send_process): Don't pass it.
15010 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15012 Fix previous change: the library cache is defined in w32.c.
15013 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
15014 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
15016 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15018 Implement dynamic loading of GnuTLS on Windows.
15020 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
15021 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
15022 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15025 * gnutls.c (Qgnutls_dll): Define.
15026 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
15027 (gnutls_*): Declare function pointers.
15028 (init_gnutls_functions): New function to initialize function pointers.
15029 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
15030 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
15031 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15032 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
15033 (emacs_gnutls_write, emacs_gnutls_read)
15034 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
15035 (Fgnutls_available_p): New function.
15036 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
15037 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
15038 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
15040 * image.c: Include w32.h.
15041 (Vimage_type_cache): Delete.
15042 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
15043 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
15044 (w32_delayed_load): Move to w32.c.
15046 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
15048 * w32.c (QCloaded_from, Vlibrary_cache): Define.
15049 (w32_delayed_load): Move from image.c. When loading a library, record
15050 its filename in the :loaded-from property of the library id.
15051 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
15052 Initialize and staticpro them.
15053 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
15055 * process.c: Include lisp.h before w32.h, not after.
15056 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
15057 instead of gnutls_record_check_pending.
15059 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
15061 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
15063 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
15064 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
15067 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
15069 * xterm.c (x_set_frame_alpha): Do not set property on anything
15070 else than FRAME_X_OUTER_WINDOW (Bug#8608).
15072 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
15074 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
15076 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
15078 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
15079 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

15085 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
15086 (Qgnutls_bootprop_callbacks_verify): Make static.
15088 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
15090 * callproc.c: Indentation fixup.
15092 * sysdep.c (wait_for_termination_1): Make static.
15093 (wait_for_termination, interruptible_wait_for_termination):
15094 Move after wait_for_termination_1.
15096 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
15098 * sysdep.c (interruptible_wait_for_termination): New function
15099 which is like wait_for_termination, but allows keyboard
15102 * callproc.c (Fcall_process): Add (:file "file") as an option for
15104 (Fcall_process_region): Ditto.
15106 2011-04-30 Eli Zaretskii <eliz@gnu.org>
15108 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
15109 rather than `XVECTOR (FOO)->size'.
15111 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
15112 inttypes.h, as a gnulib replacement is used if it not available in
15115 2011-04-21 Eli Zaretskii <eliz@gnu.org>
15117 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
15118 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
15119 of MOST_POSITIVE_FIXNUM. (Bug#8528)
15121 * coding.c (coding_alloc_by_realloc): Error out if destination
15122 will grow beyond MOST_POSITIVE_FIXNUM.
15123 (decode_coding_emacs_mule): Abort if there isn't enough place in
15124 charbuf for the composition carryover bytes. Reserve an extra
15125 space for up to 2 characters produced in a loop.
15126 (decode_coding_iso_2022): Abort if there isn't enough place in
15127 charbuf for the composition carryover bytes.
15129 2011-04-21 Eli Zaretskii <eliz@gnu.org>

15132 aborting when %lld or %lll format is passed.
15133 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
15134 %llo or %llx format is passed. (Bug#8545)
15136 * window.c (window_scroll_line_based): Use a marker instead of
15137 simple variables to record original value of point. (Bug#7952)
15139 * doprnt.c (doprnt): Fix the case where a multibyte sequence
15140 produced by %s or %c overflows available buffer space. (Bug#8545)
15142 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
15144 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
15145 (SIZE_MAX): Move defn after all includes, as they might #define it.
15147 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15149 * w32.c (init_environment): Warn about defaulting HOME to C:\.
15151 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

15154 (command_loop_1): Run `delayed-warnings-hook'
15155 if Vdelayed_warnings_list is non-nil.
15156 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
15157 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
15159 2011-04-28 Eli Zaretskii <eliz@gnu.org>
15161 * doprnt.c (doprnt): Don't return value smaller than the buffer
15162 size if the message was truncated. (Bug#8545).
15164 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15166 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
15167 (Fx_window_property): #if-0 the whole functions, not just the bodies.
15169 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15171 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
15173 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
15175 * makefile.w32-in: Update dependencies.
15177 2011-04-27 Eli Zaretskii <eliz@gnu.org>
15179 Improve `doprnt' and its usage. (Bug#8545)
15180 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
15181 `format_end'. Remove support for %l as a conversion specifier.
15182 Don't use xrealloc. Improve diagnostics when the %l size modifier
15183 is used. Update the commentary.
15185 * eval.c (verror): Simplify calculation of size_t.
15187 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
15190 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
15192 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
15195 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15197 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
15198 This makes this file independent of the recent pseudovector change.
15200 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
15202 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
15204 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
15205 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
15206 Remove unused local.
15207 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
15209 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
15210 GCC 4.6.0 optimizes based on type-based alias analysis.
15211 For example, if b is of type struct buffer * and v of type struct
15212 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
15213 != &v->size, and therefore "v->size = 1; b->size = 2; return
15214 v->size;" must therefore return 1. This assumption is incorrect
15215 for Emacs, since it type-puns struct Lisp_Vector * with many other
15216 types. To fix this problem, this patch adds a new type struct
15217 vectorlike_header that documents the constraints on layout of vectors
15218 and pseudovectors, and helps optimizing compilers not get fooled
15219 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
15220 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
15221 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
15223 (XSETPVECTYPE): Rewrite in terms of new macro.
15224 (XSETPVECTYPESIZE): New macro, specifying both type and size.
15225 This is a bit clearer, and further avoids the possibility of
15226 undesirable aliasing.
15227 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
15228 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
15229 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
15230 since Lisp_Subr is a special case (no "next" field).
15231 (ASIZE): Now uses header.size rather than size.
15232 All previous uses of XVECTOR (foo)->size replaced to use this macro,
15233 to avoid the hassle of writing XVECTOR (foo)->header.size.
15234 (struct vectorlike_header): New type.
15235 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
15236 object, to help avoid aliasing.
15237 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
15238 (SUBRP): Likewise, since Lisp_Subr is a special case.
15239 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
15240 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
15241 (struct Lisp_Hash_Table): Combine first two members into a single
15242 struct vectorlike_header member. All uses of "size" and "next" members
15243 changed to be "header.size" and "header.next".
15244 * buffer.h (struct buffer): Likewise.
15245 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
15246 * frame.h (struct frame): Likewise.
15247 * process.h (struct Lisp_Process): Likewise.
15248 * termhooks.h (struct terminal): Likewise.
15249 * window.c (struct save_window_data, struct saved_window): Likewise.
15250 * window.h (struct window): Likewise.
15251 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
15252 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
15253 * buffer.c (init_buffer_once): Likewise.
15254 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
15256 * process.c (Fformat_network_address): Use local var for size,
15259 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
15261 Make the Lisp reader and string-to-float more consistent (Bug#8525)
15262 * data.c (atof): Remove decl; no longer used or needed.
15263 (digit_to_number): Move to lread.c.
15264 (Fstring_to_number): Use new string_to_number function, to be
15265 consistent with how the Lisp reader treats infinities and NaNs.
15266 Do not assume that floating-point numbers represent EMACS_INT
15267 without losing information; this is not true on most 64-bit hosts.
15268 Avoid double-rounding errors, by insisting on integers when
15269 parsing non-base-10 numbers, as the documentation specifies.
15270 * lisp.h (string_to_number): New decl, replacing ...
15271 (isfloat_string): Remove.
15272 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
15273 (read1): Do not accept +. and -. as integers; this
15274 appears to have been a coding error. Similarly, do not accept
15275 strings like +-1e0 as floating point numbers. Do not report
15276 overflow for integer overflows unless the base is not 10 which
15277 means we have no simple and reliable way to continue.
15278 Break out the floating-point parsing into a new
15279 function string_to_number, so that Fstring_to_number parses
15280 floating point numbers consistently with the Lisp reader.
15281 (digit_to_number): Move here from data.c. Make it static inline.
15282 (E_CHAR, EXP_INT): Remove, replacing with ...
15283 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
15284 (string_to_number): New function, replacing isfloat_string.
15285 This function checks for valid syntax and produces the resulting
15286 Lisp float number too. Rework it so that string-to-number
15287 no longer mishandles examples like "1.0e+". Use strtoumax,
15288 so that overflow for non-base-10 numbers is reported only when
15289 there's no portable and simple way to convert to floating point.
15291 * textprop.c (set_text_properties_1): Rewrite for clarity,
15292 and to avoid GCC warning about integer overflow.
15294 * intervals.h (struct interval): Use EMACS_INT for members
15295 where EMACS_UINT might cause problems. See
15296 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
15297 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
15298 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
15300 (offset_intervals): Tell GCC not to worry about length overflow
15301 when negating a negative length.
15303 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
15304 (overrun_check_free): Likewise.
15306 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
15307 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
15310 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15311 (gnutls_make_error): Rename local to avoid shadowing.
15312 (gnutls_emacs_global_deinit): ifdef out; not used.
15313 (Fgnutls_boot): Use const for pointer to readonly storage.
15314 Comment out unused local. Fix pointer signedness problems.
15316 * lread.c (openp): Don't stuff size_t into an 'int'.
15317 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
15318 about possible signed overflow.
15320 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15321 (GDK_KEY_g): Don't define if already defined.
15322 (xg_prepare_tooltip): Avoid pointer signedness problem.
15323 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
15325 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
15326 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
15328 * xfns.c (Fx_window_property): Simplify a bit,
15329 to make a bit faster and to avoid GCC 4.6.0 warning.
15330 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
15332 * fns.c (internal_equal): Don't assume size_t fits in int.
15334 * alloc.c (compact_small_strings): Tighten assertion a little.
15336 Replace pEd with more-general pI, and fix some printf arg casts.
15337 * lisp.h (pI): New macro, generalizing old pEd macro to other
15338 conversion specifiers. For example, use "...%"pI"d..." rather
15339 than "...%"pEd"...".
15340 (pEd): Remove. All uses replaced with similar uses of pI.
15341 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
15342 * alloc.c (check_pure_size): Don't overflow by converting size to int.
15343 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
15344 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
15345 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
15346 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
15347 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
15349 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
15350 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
15351 * print.c (safe_debug_print, print_object): Likewise.
15352 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
15354 Use pI instead of if-then-else-abort. Use %p to avoid casts,
15355 avoiding the 0 flag, which is not portable.
15356 * process.c (Fmake_network_process): Use pI to avoid cast.
15357 * region-cache.c (pp_cache): Likewise.
15358 * xdisp.c (decode_mode_spec): Likewise.
15359 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
15360 behavior on 64-bit hosts with printf arg.
15361 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
15362 (x_stop_queuing_selection_requests): Likewise.
15363 (x_get_window_property): Don't truncate byte count to an 'int'
15366 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
15367 here, since it parses constructs like leading '-' and spaces,
15368 which are not wanted; and it overflows with large numbers.
15369 Instead, simply match F[0-9]+, which is what is wanted anyway.
15371 * alloc.c: Remove unportable assumptions about struct layout.
15372 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
15373 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
15374 (allocate_vectorlike, make_pure_vector): Use the new macros,
15375 plus offsetof, to remove unportable assumptions about struct layout.
15376 These assumptions hold on all porting targets that I know of, but
15377 they are not guaranteed, they're easy to remove, and removing them
15378 makes further changes easier.
15380 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
15381 This doesn't fix a bug but makes the code clearer.
15382 (string_overrun_cookie): Now const. Use initializers that
15383 don't formally overflow signed char, to avoid warnings.
15384 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
15385 can cause Emacs to crash when string overrun checking is enabled.
15386 (allocate_buffer): Don't assume sizeof (struct buffer) is a
15387 multiple of sizeof (EMACS_INT); it need not be, if
15388 alignof(EMACS_INT) < sizeof (EMACS_INT).
15389 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
15391 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

15395 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
15397 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
15398 supposed to be handshaking. (Bug#8556)
15399 Reported by Paul Eggert <eggert@cs.ucla.edu>.
15401 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
15403 * lisp.h (Qdebug): List symbol.
15404 * eval.c (Qdebug): Restore global linkage.

15406 (handle_user_signal): Break into debugger when debug-on-event
15407 matches the current signal symbol.
15409 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
15411 * alloc.c (check_sblock, check_string_bytes)
15412 (check_string_free_list): Convert to standard C.
15414 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
15416 * w32.c (emacs_gnutls_push): Fix typo.
15418 2011-04-25 Eli Zaretskii <eliz@gnu.org>
15420 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
15421 "cast to pointer from integer of different size".
15423 Improve doprnt and its use in verror. (Bug#8545)
15424 * doprnt.c (doprnt): Document the set of format control sequences
15425 supported by the function. Use SAFE_ALLOCA instead of always
15428 * eval.c (verror): Don't limit the buffer size at size_max-1, that
15429 is one byte too soon. Don't use xrealloc; instead xfree and
15432 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
15434 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
15437 * gnutls.c: Renamed global_initialized to
15438 gnutls_global_initialized. Added internals for the
15439 :verify-hostname-error, :verify-error, and :verify-flags
15440 parameters of `gnutls-boot' and documented those parameters in the
15441 docstring. Start callback support.
15442 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
15443 unless a fatal error occurred. Call gnutls_alert_send_appropriate
15444 on error. Return error code.
15445 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
15446 (emacs_gnutls_read): Likewise.
15447 (Fgnutls_boot): Return handshake error code.
15448 (emacs_gnutls_handle_error): New function.
15449 (wsaerror_to_errno): Likewise.

15460 buffered some data internally if no FDs are set for TLS
15463 * makefile.w32-in (OBJ2): Add gnutls.$(O).

15511 <char-direction-table>: Deleted.
15513 2011-04-23 Eli Zaretskii <eliz@gnu.org>
15515 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
15516 * doprnt.c: Include limits.h.
15517 (SIZE_MAX): New macro.
15518 (doprnt): Return a size_t value. 2nd arg is now size_t.
15519 Many local variables are now size_t instead of int or unsigned.
15520 Improve overflow protection. Support `l' modifier for integer
15521 conversions. Support %l conversion. Don't assume an EMACS_INT
15522 argument for integer conversions and for %c.
15524 * lisp.h (doprnt): Restore prototype.
15526 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
15527 $(SRC)/character.h.
15529 * Makefile.in (base_obj): Add back doprnt.o.
15531 * deps.mk (doprnt.o): Add back prerequisites.
15532 (callint.o): Depend on character.h.
15534 * eval.c (internal_lisp_condition_case): Include the handler
15535 representation in the error message.
15536 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
15537 when breaking from the loop.
15539 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
15541 * callint.c (Fcall_interactively): When displaying error message
15542 about invalid control letter, pass the character's codepoint, not
15543 a pointer to its multibyte form. Improve display of the character
15544 in octal and display also its hex code.
15546 * character.c (char_string): Use %x to display the (unsigned)
15547 codepoint of an invalid character, to avoid displaying a bogus
15550 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15551 `error', not SYMBOL_NAME itself.
15553 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
15554 character arguments to `error'.
15556 * charset.c (check_iso_charset_parameter): Fix incorrect argument
15557 to `error' in error message about FINAL_CHAR argument. Make sure
15558 FINAL_CHAR is a character, and use %c when it is passed as
15559 argument to `error'.

15623 Define only if needed.
15625 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
15626 by pacifying GCC about it. Maybe it's time to retire it?
15627 * xfaces.c (USG, __TIMEVAL__): Likewise.
15629 * dispextern.h (struct redisplay_interface): Rename param
15630 to avoid shadowing.

15678 compatible char. Avoid the old compiler warnings about
15679 out-of-range initializers by using, for example, '\xab' rather
15682 * xgselect.c (xgselect_initialize): Check vs interface
15683 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

15748 * nsfont.m: Fixed bugs in ns_get_family and
15749 ns_descriptor_to_entity that were caused by using free to
15750 deallocate memory blocks that were allocated by xmalloc (via
15751 xstrdup). This caused Emacs to crash when compiled with
15752 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
15753 --enable-checking=xmallocoverrun). xfree is now used to
15754 deallocate these memory blocks.

15768 (emacs_read, emacs_write): Remove check for negative size, as the
15769 Emacs source code has been audited now.
15770 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
15771 (emacs_read, emacs_write): Use it.
15772 * process.c (send_process): Adjust to the new signatures of
15773 emacs_write and emacs_gnutls_write. Do not attempt to store
15774 a byte offset into an 'int'; it might overflow.
15775 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

16109 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
16110 * dispextern.h (bidi_dump_cached_states): Remove, since it's
16111 exported only to the debugger.
16113 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
16114 * atimer.h (run_all_atimers): Remove; not exported.
16116 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
16117 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
16118 was inaccessible from Lisp.
16119 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
16120 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
16122 alloc.c: Import and export fewer symbols, and remove unused items.
16123 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
16125 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
16126 it's not optimized away by whole-program optimization.

16139 (mark_backtrace): Define only if BYTE_MARK_STACK.
16140 * xdisp.c (message_enable_multibyte): Now static.
16142 Declare Lisp_Object Q* variables to be 'static' if not exported.
16143 This makes it easier for human readers (and static analyzers)
16144 to see whether these variables are used from other modules.
16145 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

16156 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
16158 * lisp.h (DEFINE_FUNC): Make sname 'static'.
16160 Make Emacs functions such as Fatom 'static' by default.
16161 This makes it easier for human readers (and static analyzers)
16162 to see whether these functions can be called from other modules.
16163 DEFUN now defines a static function. To make the function external
16164 so that it can be used in other C modules, use the new macro DEFUE.

16170 Remove decls, since these functions are now static.
16171 (Funintern, Fget_internal_run_time): New decls, since these functions
16172 were already external.

16182 Mark functions with DEFUE instead of DEFUN,
16183 if they are used in other modules.

16185 decls for now-static functions.
16186 * buffer.h (Fdelete_overlay): Remove decl.

16222 2011-04-13 Eli Zaretskii <eliz@gnu.org>
16224 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
16225 when at ZV. (Bug#8487)
16227 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>

16237 * alloc.c (overrun_check_malloc, overrun_check_realloc)
16238 (overrun_check_free): Protoize.
16240 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
16242 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
16243 since callers should never pass a negative size.
16244 Change the signature to match that of plain 'read' and 'write'; see
16245 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
16246 * lisp.h: Update prototypes of emacs_write and emacs_read.
16248 2011-04-11 Eli Zaretskii <eliz@gnu.org>
16250 * xdisp.c (redisplay_window): Don't try to determine the character
16251 position of the scroll margin if the window start point w->startp
16252 is outside the buffer's accessible region. (Bug#8468)
16254 2011-04-10 Eli Zaretskii <eliz@gnu.org>
16256 Fix write-region and its subroutines for buffers > 2GB.
16257 * fileio.c (a_write, e_write): Modify declaration of arguments and
16258 local variables to support buffers larger than 2GB.
16259 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
16261 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
16262 argument, local variables, and return value.
16264 * lisp.h: Update prototypes of emacs_write and emacs_read.
16266 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
16268 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
16270 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
16272 Fix more problems found by GCC 4.6.0's static checks.
16274 * xdisp.c (vmessage): Use a better test for character truncation.
16276 * charset.c (load_charset_map): <, not <=, for optimization,
16277 and to avoid potential problems with integer overflow.
16278 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
16279 * casetab.c (set_identity, shuffle): Likewise.
16280 * editfns.c (Fformat): Likewise.
16281 * syntax.c (skip_chars): Likewise.
16283 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
16284 This also lets GCC 4.6.0 generate slightly better loop code.
16286 * callint.c (Fcall_interactively): <, not <=, for optimization.
16287 (Fcall_interactively): Count the number of arguments produced,
16288 not the number of arguments given. This is simpler and lets GCC
16289 4.6.0 generate slightly better code.
16291 * ftfont.c: Distingish more carefully between FcChar8 and char.
16292 The previous code passed unsigned char * to a functions like
16293 strlen and xstrcasecmp that expect char *, which does not
16294 conform to the C standard.
16295 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
16296 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
16297 char * when the C standard requires it.
16299 * keyboard.c (read_char): Remove unused var.
16301 * eval.c: Port to Windows vsnprintf (Bug#8435).
16302 Include <limits.h>.
16303 (SIZE_MAX): Define if the headers do not.
16304 (verror): Do not give up if vsnprintf returns a negative count.
16305 Instead, grow the buffer. This ports to Windows vsnprintf, which
16306 does not conform to C99. Problem reported by Eli Zaretskii.
16307 Also, simplify the allocation scheme, by avoiding the need for
16308 calling realloc, and removing the ALLOCATED variable.
16310 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
16312 Remove invocations of doprnt, as Emacs now uses vsnprintf.
16313 But keep the doprint source code for now, as we might revamp it
16314 and use it again (Bug#8435).
16315 * lisp.h (doprnt): Remove.
16316 * Makefile.in (base_obj): Remove doprnt.o.
16317 * deps.mk (doprnt.o): Remove.
16319 error: Print 32- and 64-bit integers portably (Bug#8435).
16320 Without this change, on typical 64-bit hosts error ("...%d...", N)
16321 was used to print both 32- and 64-bit integers N, which relied on
16322 undefined behavior.
16323 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
16324 * lisp.h (error, verror): Mark as printf-like functions.
16325 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
16326 Report overflow in size calculations when allocating printf buffer.
16327 Do not truncate output string at its first null byte.
16328 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
16329 Truncate the output at a character boundary, since vsnprintf does not
16331 * charset.c (check_iso_charset_parameter): Convert internal
16332 character to string before calling 'error', since %c now has the
16334 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
16335 overflow when computing char to be passed to 'error'. Do not
16336 pass Lisp_Object to 'error'; pass the integer instead.
16337 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
16338 formatted with plain %d.
16340 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
16342 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
16344 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
16346 * xterm.c (x_catch_errors): Remove duplicate declaration.
16348 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
16350 * xdisp.c, lisp.h (message_nolog): Remove; unused.
16352 2011-04-10 Jim Meyering <meyering@redhat.com>
16354 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
16355 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
16356 return ssize_t not "int", and use size_t as the buffer length.
16357 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
16358 * gnutls.h: Update declarations.
16359 * process.c (read_process_output): Use ssize_t, to match.
16360 (send_process): Likewise.
16362 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16364 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
16366 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16368 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
16369 Use unsigned char, to match FcChar8 type definition.
16371 * xterm.c (handle_one_xevent):
16372 * xmenu.c (create_and_show_popup_menu):
16373 * xselect.c (x_decline_selection_request)
16374 (x_reply_selection_request): Avoid type-punned deref of X events.
16376 2011-04-09 Eli Zaretskii <eliz@gnu.org>
16378 Fix some uses of `int' instead of EMACS_INT.
16379 * search.c (string_match_1, fast_string_match)
16380 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
16381 (scan_buffer, find_next_newline_no_quit)
16382 (find_before_next_newline, search_command, Freplace_match)
16383 (Fmatch_data): Make some `int' variables be EMACS_INT.
16385 * xdisp.c (display_count_lines): 3rd argument and return value now
16386 EMACS_INT. All callers changed.
16387 (pint2hrstr): Last argument is now EMACS_INT.
16389 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
16390 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
16391 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

16402 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
16403 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
16405 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
16406 (encode_invocation_designation): Last argument P_NCHARS is now
16408 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
16409 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
16411 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
16414 * ccl.c (Fccl_execute_on_string): Declare some variables
16417 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
16419 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
16421 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
16423 * process.c (Fformat_network_address): Doc fix.
16425 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
16427 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
16429 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
16431 * keyboard.c (read_char): Call Lisp function help-form-show,
16432 instead of using internal_with_output_to_temp_buffer.
16433 (Qhelp_form_show): New var.
16434 (syms_of_keyboard): Use DEFSYM macro.
16436 * print.c (internal_with_output_to_temp_buffer): Function deleted.

16443 (list_processes_1): Delete.
16445 2011-04-06 Eli Zaretskii <eliz@gnu.org>
16447 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
16449 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
16451 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
16453 Fix more problems found by GCC 4.6.0's static checks.

16475 This avoids several warnings with gcc -Wstrict-overflow.
16476 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
16477 directly, rather than having caller test rule sign. This avoids
16478 some unnecessary tests.
16479 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
16480 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
16481 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
16483 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16484 (xfont_open): Avoid unnecessary tests.
16486 * composite.c (composition_gstring_put_cache): Use unsigned integer.
16488 * composite.h, composite.c (composition_gstring_put_cache):
16489 Use EMACS_INT, not int, for length.
16491 * composite.h (COMPOSITION_DECODE_REFS): New macro,
16492 breaking out part of COMPOSITION_DECODE_RULE.
16493 (COMPOSITION_DECODE_RULE): Use it.
16494 * composite.c (get_composition_id): Remove unused local vars,
16495 by using the new macro.
16497 * textprop.c (set_text_properties_1): Change while to do-while,
16498 since the condition is always true at first.
16500 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16501 (interval_deletion_adjustment): Return unsigned value.
16504 * process.c (list_processes_1, create_pty, read_process_output):
16505 (exec_sentinel): Remove vars that were set but not used.
16506 (create_pty): Remove unnecessary "volatile"s.
16507 (Fnetwork_interface_info): Avoid possibility of int overflow.
16508 (read_process_output): Do adaptive read buffering even if carryover.
16509 (read_process_output): Simplify nbytes computation if buffered.

16517 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
16518 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
16520 * print.c (print_error_message): Avoid int overflow.
16522 * font.c (font_list_entities): Redo for clarity,
16523 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
16525 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
16526 (font_score): Avoid potential overflow in diff calculation.
16528 * fns.c (substring_both): Remove var that is set but not used.
16529 (sxhash): Redo loop for clarity and to avoid wraparound warning.
16531 * eval.c (funcall_lambda): Rename local to avoid shadowing.
16533 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
16534 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
16535 can always succeed if overflow has undefined behavior.
16537 * search.c (boyer_moore, wordify): Remove vars set but not used.
16538 (wordify): Omit three unnecessary tests.
16540 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
16541 All callers changed. This avoids the need for an unused var.
16543 * casefiddle.c (casify_region): Remove var that is set but not used.
16545 * dired.c (file_name_completion): Remove var that is set but not used.
16547 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
16549 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16550 (Finsert_file_contents): Remove unnecessary code checking fd.
16552 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
16553 Check for integer overflow on size calculations.
16555 * buffer.c (Fprevious_overlay_change): Remove var that is set
16558 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16559 Remove vars that are set but not used.
16560 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16561 (timer_check_2): Mark vars as initialized.
16563 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16565 * image.c (lookup_image): Remove var that is set but not used.
16566 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16568 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16569 that are set but not used.
16571 * xfns.c (make_invisible_cursor): Don't return garbage
16572 if XCreateBitmapFromData fails (Bug#8410).
16574 * xselect.c (x_get_local_selection, x_handle_property_notify):
16575 Remove vars that are set but not used.
16577 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
16578 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
16580 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
16581 Remove var that is set but not used.
16582 (scroll_bar_windows_size): Now size_t, not int.
16583 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16584 Check for overflow.
16586 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16587 (map_tty_color) [!defined MSDOS]: Likewise.
16589 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16591 * coding.c: Remove vars that are set but not used.
16592 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
16593 All callers changed.
16594 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
16595 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
16596 (decode_coding_charset): Remove vars that are set but not used.
16598 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
16599 that is set but not used.
16601 * print.c (print_object): Remove var that is set but not used.
16603 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16604 The gnulib version avoids calling malloc in the usual case,
16605 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16606 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16607 * filelock.c (current_lock_owner): Likewise.
16608 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16609 * sysdep.c: Include allocator.h, careadlinkat.h.
16610 (emacs_no_realloc_allocator): New static constant.
16611 (emacs_readlink): New function.
16612 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16613 ../lib/careadlinkat.h.
16615 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
16617 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
16618 first non-nil return value).
16620 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
16622 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
16623 if not defined (Bug#8403).
16625 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16627 * xdisp.c (display_count_lines): Remove parameter `start',
16628 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16629 (get_char_face_and_encoding): Remove parameter `multibyte_p',
16630 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

16632 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
16633 and thereabouts. All callers changed.
16634 (get_per_char_metric): Remove parameter `f', unused since
16635 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
16637 2011-04-02 Jim Meyering <meyering@redhat.com>
16639 do not dereference NULL upon failed strdup
16640 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16641 (ns_get_family): Likewise.
16643 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16645 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16647 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16649 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16652 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16654 Add lexical binding.
16656 * window.c (Ftemp_output_buffer_show): New fun.
16657 (Fsave_window_excursion):
16658 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
16660 * lread.c (lisp_file_lexically_bound_p): New function.
16661 (Fload): Bind Qlexical_binding.
16662 (readevalloop): Remove `evalfun' arg.
16663 Bind Qinternal_interpreter_environment.
16664 (Feval_buffer): Bind Qlexical_binding.
16665 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16667 (syms_of_lread): Declare `lexical-binding'.
16669 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16671 * keyboard.c (eval_dyn): New fun.
16672 (menu_item_eval_property): Use it.
16674 * image.c (parse_image_spec): Use Ffunctionp.
16676 * fns.c (concat, mapcar1): Accept byte-code-functions.
16678 * eval.c (Fsetq): Handle lexical vars.
16679 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16680 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16681 (FletX, Flet): Obey lexical binding.
16682 (Fcommandp): Handle closures.
16683 (Feval): New `lexical' arg.
16684 (eval_sub): New function extracted from Feval. Use it almost
16685 everywhere where Feval was used. Look up vars in lexical env.
16687 (Ffunctionp): Move from subr.el.
16688 (Ffuncall): Handle closures.
16689 (apply_lambda): Remove `eval_flags'.
16690 (funcall_lambda): Handle closures and new byte-code-functions.
16691 (Fspecial_variable_p): New function.
16692 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16693 but without exporting it to Lisp.
16695 * doc.c (Fdocumentation, store_function_docstring):
16696 * data.c (Finteractive_form): Handle closures.
16698 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16701 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16703 (exec_byte_code): New function extracted from Fbyte_code to handle new
16704 calling convention for byte-code-functions. Add new byte-codes.
16706 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
16708 * alloc.c (Fmake_symbol): Init new `declared_special' field.
16710 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16712 * xdisp.c (redisplay_internal): Fix prototype.
16714 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16716 * xdisp.c (SCROLL_LIMIT): New macro.
16717 (try_scrolling): Use it when setting scroll_limit.
16718 Limit scrolling to 100 screen lines.
16719 (redisplay_window): Even when falling back on "recentering",
16720 position point in the window according to scroll-conservatively,
16721 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16723 (try_scrolling): When point is above the window, allow searching
16724 as far as scroll_max, or one screenful, to compute vertical
16725 distance from PT to the scroll margin position. This prevents
16726 try_scrolling from unnecessarily failing when
16727 scroll-conservatively is set to a value slightly larger than the
16728 window height. Clean up the case of PT below the margin at bottom
16729 of window: scroll_max can no longer be INT_MAX. When aggressive
16730 scrolling is in use, don't let point enter the opposite scroll
16731 margin as result of the scroll.
16732 (syms_of_xdisp) <scroll-conservatively>: Document the
16733 threshold of 100 lines for never-recentering scrolling.
16735 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16737 * dispextern.h (move_it_by_lines):

16740 (message_log_check_duplicate): Remove parameters `prev_bol' and
16741 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16742 (redisplay_internal): Remove parameter `preserve_echo_area',
16743 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16745 * indent.c (Fvertical_motion):
16746 * window.c (window_scroll_pixel_based, Frecenter):
16747 Don't pass `need_y_p' to `move_it_by_lines'.
16749 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16751 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16752 steal a few bits to be more compact.
16753 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16754 Remove unneeded casts.
16756 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16758 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16760 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16761 binding" message (bug#7967).
16763 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16765 Fix more problems found by GCC 4.6.0's static checks.
16767 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16768 Remove unused local var.
16770 * editfns.c (Fmessage_box): Remove unused local var.
16772 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16773 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16774 Omit unused local vars.
16775 * window.c (shrink_windows): Omit unused local var.
16776 * menu.c (digest_single_submenu): Omit unused local var.
16777 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16778 Omit unused local var.
16780 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16781 Don't assume string length fits in int.
16782 (keyremap_step, read_key_sequence): Use size_t for sizes.
16783 (read_key_sequence): Don't check last_real_key_start redundantly.
16785 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
16786 instead of alloca (Bug#8344).
16788 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16789 (Fbacktrace_frame): Don't assume nframes fits in int.
16791 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

16796 * term.c (produce_glyphless_glyph): Remove unnecessary test.
16798 * cm.c (calccost): Turn while-do into do-while, for clarity.
16800 * keyboard.c (syms_of_keyboard): Use the same style as later
16801 in this function when indexing through an array. This also
16802 works around GCC bug 48267.
16804 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16806 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16808 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16809 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16811 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16812 This avoids undefined behavior on integer overflow, and is a bit
16813 more convenient anyway since it is compared to a size_t variable.
16815 Variadic C functions now count arguments with size_t, not int.
16816 This avoids an unnecessary limitation on 64-bit machines, which
16817 caused (substring ...) to crash on large vectors (Bug#8344).
16818 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
16819 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

16827 * fns.c (concat): Likewise.
16828 * frame.c (x_set_frame_parameters): Likewise.
16829 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16830 0 if not found, not -1. All callers changed.
16832 * alloc.c (garbage_collect): Don't assume stack size fits in int.
16833 (stack_copy_size): Now size_t, not int.
16834 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
16836 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
16838 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
16839 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
16840 All callers changed.
16842 * lisp.h (multibyte_char_to_unibyte):
16843 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
16844 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

16855 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
16856 don't set the hook to nil, but remove the offending function instead.
16857 (Qcommand_hook_internal): Remove, unused.
16858 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
16859 Vcommand_hook_internal.
16861 * eval.c (enum run_hooks_condition): Remove.
16862 (funcall_nil, funcall_not): New functions.
16863 (run_hook_with_args): Call each function through a `funcall' argument.
16864 Remove `cond' argument, now redundant.

16877 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
16878 All callers changed.
16880 * w32.c (_wsa_errlist): Use braces for struct initializers.
16882 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
16883 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
16884 All callers changed.

17029 * term.c (Fsuspend_tty, Fresume_tty):
17030 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
17031 * window.c (temp_output_buffer_show):

17040 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
17042 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
17043 unconditionally since it does the check itself.
17045 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
17047 Fix more problems found by GCC 4.5.2's static checks.
17049 * coding.c (encode_coding_raw_text): Avoid unnecessary test
17050 the first time through the loop, since we know p0 < p1 then.
17051 This also avoids a gcc -Wstrict-overflow warning.
17053 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
17054 leading to a memory leak, possible in functions like
17055 load_charset_map_from_file that can allocate an unbounded number
17056 of objects (Bug#8318).
17058 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
17059 that could (at least in theory) be that large.
17061 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
17062 This is less likely to overflow, and avoids undefined behavior if
17063 overflow does occur. All callers changed. Use strtoul to scan
17064 for the unsigned long integer.
17065 (pint2hrstr): Simplify and tune code slightly.
17066 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
17068 * scroll.c (do_scrolling): Work around GCC bug 48228.
17069 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

17076 * fileio.c (Fcopy_file): Report error if fchown or fchmod
17079 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
17081 * process.c (Fmake_network_process): Use socklen_t, not int,
17082 where POSIX says socklen_t is required in portable programs.
17083 This fixes a porting bug on hosts like 64-bit HP-UX, where
17084 socklen_t is wider than int (Bug#8277).
17085 (Fmake_network_process, server_accept_connection):
17086 (wait_reading_process_output, read_process_output):
17089 * process.c: Rename or move locals to avoid shadowing.

17099 Make tparam.h and terminfo.c consistent.
17100 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
17101 Include tparam.h instead, since it declares them.
17102 * cm.h (PC): Remove extern decl; tparam.h now does this.
17103 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
17104 * terminfo.c: Include tparam.h, to check interfaces.
17105 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
17106 (tparam): Adjust signature to match interface in tparam.h;
17107 this removes some undefined behavior. Check that outstring and len
17108 are zero, which they always are with Emacs.
17109 * tparam.h (PC, BC, UP): New extern decls.
17111 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
17112 (xftfont_open): Rename locals to avoid shadowing.
17114 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

17126 * composite.c (composition_compute_stop_pos): Rename local to
17128 (composition_reseat_it): Remove unused locals.
17129 (find_automatic_composition, composition_adjust_point): Likewise.
17130 (composition_update_it): Mark var as initialized.
17131 (find_automatic_composition): Mark vars as initialized,
17132 with a FIXME (Bug#8290).

17136 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
17137 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
17138 (BUF_DEC_POS): Be more systematic about renaming local temporaries
17139 to avoid shadowing.
17141 * textprop.c (property_change_between_p): Remove; unused.
17143 * intervals.c (interval_start_pos): Now static.
17145 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

17151 Fix pointer signedness.
17152 (alsa_choose_format): Remove unused local var.
17153 (wav_play): Initialize a variable to 0, to prevent undefined
17154 behavior (Bug#8278).
17156 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
17158 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
17160 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
17161 clobbering (Bug#8298).
17162 * sysdep.c (sys_subshell): Likewise.
17163 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
17165 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
17166 This should get cleaned up, so that child_setup has the
17167 same signature on all platforms.
17169 * callproc.c (call_process_cleanup): Now static.
17170 (relocate_fd): Rename locals to avoid shadowing.
17172 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
17174 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
17175 not to be necessary, and produces flickering.
17177 2011-03-20 Glenn Morris <rgm@gnu.org>
17179 * config.in: Remove file.
17181 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
17183 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
17184 are now in src/globals.h.
17185 (syms_of_minibuf): Remove spurious & from previous change.

17211 (sigchld_handler): Now static.
17213 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
17214 That way, the code declares only the vars that it needs.

17224 (CONSTANTLIM): Remove; unused.
17225 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
17226 Define only if needed.
17228 * unexelf.c (unexec): Name an expression,
17229 to avoid gcc -Wbad-function-cast warning.
17230 Use a different way to cause a compilation error if anyone uses
17231 n rather than nn, a way that does not involve shadowing.
17232 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
17234 * deps.mk (unexalpha.o): Remove; unused.
17236 New file unexec.h, the (simple) interface for unexec (Bug#8267).

17302 (Fformat_time_string, Fencode_time, Finsert_char):
17303 (Ftranslate_region_internal, Fformat):
17304 Rename or remove local vars to avoid shadowing.

17307 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
17310 * lisp.h (eassert): Check that the argument compiles, even if
17311 ENABLE_CHECKING is not defined.
17313 * data.c (Findirect_variable): Name an expression, to avoid
17314 gcc -Wbad-function-cast warning.

17331 (Fmemory_limit): Cast sbrk's returned value to char *.
17333 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

17341 to use the following functions instead of these macros.
17342 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
17343 EMACS_INT, since callers assume the returned value fits in int.

17357 (RETALLOC_IF): Define only if needed.
17358 (WORDCHAR_P): Likewise. This one is never needed, but is used
17359 only in a comment talking about a compiler bug, so put inside
17360 the #if 0 of that comment.

17390 gcpro1, gcpro2, etc.
17391 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
17393 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second

17409 (downcase, upcase1): New static inline functions.
17410 (DOWNCASE, UPCASE1): Reimplement using these functions.
17411 This avoids undefined behavior in expressions like

17445 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

17452 * buffer.c (fix_overlays_before): Mark locals as initialized.
17453 (fix_start_end_in_overlays): Likewise. This function should be
17454 simplified by using pointers-to-pointers, but that's a different

17463 to suppress a gcc -Wclobbered warning that does not seem to be right.
17464 (MAXPATHLEN): Define only if needed.
17466 * process.c (serial_open, serial_configure): Move decls from here ...
17467 * systty.h: ... to here, so that they can be checked.

17813 a block, when the outer 'i' will do.

17826 -Wuninitialized does not deduce are never used uninitialized.
17827 (detect_coding_iso_2022): Initialize a local variable that might
17828 be used uninitialized. Leave a FIXME because it's not clear that
