8 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
10 Move Vlibrary_cache to emacs.c and reset before dumping.
12 * lisp.h (reset_image_types): Declare.
13 [WINDOWSNT] (Vlibrary_cache): Declare.
15 * image.c (reset_image_types): New function.
17 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

26 2012-09-25 Eli Zaretskii <eliz@gnu.org>
28 * w32proc.c (sys_signal): Handle all signals defined by the
29 MS-Windows runtime, not just SIGCHLD. Actually install the signal
30 handlers for signals supported by Windows. Don't override
31 term_ntproc as the handler for SIGABRT.
32 (sigaction): Rewrite to call sys_signal instead of duplicating its
34 (sys_kill): Improve commentary.
36 * w32.c (term_ntproc): Accept (and ignore) one argument, for
37 consistency with a signature of a signal handler. All callers
39 (init_ntproc): Accept an argument DUMPING. If dumping, don't
40 install term_ntproc as a signal handler for SIGABRT, as that
41 should be done by the dumped Emacs.
43 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
45 * w32select.c (term_w32select): Protect against repeated
46 invocation by setting clipboard_owner to NULL after calling
49 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
50 and term_ntproc to their modified signatures.
52 * character.c (char_string, string_char): Remove calls to

64 when encountering an unknown bytecode.
66 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
68 image.c, indent.c: Use bool for booleans.
69 * dispextern.h (struct image_type): Members valid_p, load, init
70 now return bool, not int. All uses changed.
71 * image.c: Omit unnecessary static decls.
72 (x_create_bitmap_mask, x_build_heuristic_mask):
73 Return void, not int, since callers don't care about the return value.

111 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
112 (interruptible_wait_for_termination):
113 Move these decls from lisp.h to syswait.h, since they use pid_t.
114 Needed on FreeBSD; see Herbert J. Skuhra in
115 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.

137 * gtkutil.c (xg_update_frame_menubar):
138 * xmenu.c (update_frame_menubar):

164 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
165 fatal_error_backtrace.
167 * w32proc.c (sys_kill): Undo last change: don't do anything when
168 invoked to deliver SIGABRT to our own process. This is now
169 handled by emacs_raise.
171 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
173 * w32term.c (w32_read_socket): Remove leftover reference to
174 interrupt_input_pending.
176 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
178 Do not use SA_NODEFER.
179 Problem reported by Dani Moncayo in
180 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
182 * sysdep.c (emacs_abort): Do not reset signal handler.
183 * emacs.c (terminate_due_to_signal): Reset signal handler here.
184 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
185 wanted even on POSIXish hosts, and it doesn't work on Windows.
187 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
189 * xterm.c (x_term_init): Call fixup_locale before and after calling
190 gtk_init (Bug#12392).
192 2012-09-23 Chong Yidong <cyd@gnu.org>
194 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
195 Vdynamic_library_alist.
197 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
198 (Fgnutls_available_p): Caller changed.
200 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
201 (Flibxml_parse_xml_region): Likewise.
203 * dispextern.h (struct image_type): Remove arg from init function.
205 * image.c (Finit_image_library, lookup_image_type)
206 (define_image_type): Remove now-unneeded second arg.
207 (init_xpm_functions, init_png_functions, init_jpeg_functions)
208 (init_tiff_functions, init_gif_functions, init_svg_functions):
209 Arglist and w32_delayed_load calling convention changed.
210 (gs_type): Remove init_gs_functions; there is no such function.
211 (valid_image_p, make_image): Fix caller to lookup_image_type.
213 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
215 Simplify and avoid signal-handling races (Bug#12471).
217 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
218 Avoid recursive loop if there's a fatal error in the function itself.
219 * atimer.c (pending_atimers):
220 * blockinput.h: Don't include "atimer.h"; no longer needed.
221 (interrupt_input_pending): Remove. All uses removed.
222 pending_signals now counts both atimers and ordinary interrupts.
223 This is less racy than having three separate pending-signal flags.
224 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
226 Rename from their upper-case counterparts BLOCK_INPUT,
227 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
228 INPUT_BLOCKED_P, and turn into functions. All uses changed.
229 This makes it easier to access volatile variables more accurately.
230 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
231 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
232 that's more reliable if the code is buggy and sets
233 interrupt_input_blocked to a negative value. All uses changed.
234 * atimer.c (deliver_alarm_signal):
235 Remove. No need to deliver this to the parent; any thread can
236 handle this signal now. All uses replaced by underlying handler.
237 * atimer.c (turn_on_atimers):
238 * dispnew.c (handle_window_change_signal):
239 * emacs.c (handle_danger_signal):
240 * keyboard.c (kbd_buffer_get_event):
241 Don't reestablish signal handler; not needed with sigaction.
242 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
244 Rework to avoid unnecessary accesses to volatile variables.
245 (UNBLOCK_INPUT_TO): Now a function.
246 (totally_unblock_input, unblock_input): New decls.
247 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
248 (init_data): Remove. Necessary stuff now done in init_signal.
249 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
250 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
251 (fatal_error_code): Remove; no longer needed.
252 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
253 it doesn't always backtrace. All uses changed. No need to reset
254 signal to default, since sigaction and/or die does that for us now.
255 Use emacs_raise (FOO), not kill (getpid (), FOO).
256 (main): Check more-accurately whether we're dumping.
257 Move fatal-error setup to sysdep.c
258 * floatfns.c: Do not include "syssignal.h"; no longer needed.
259 * gtkutil.c (xg_get_file_name, xg_get_font):
260 Remove no-longer-needed signal-mask manipulation.
261 * keyboard.c, process.c (POLL_FOR_INPUT):
262 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
263 * keyboard.c (read_avail_input): Remove.
264 All uses replaced by gobble_input.
265 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
266 (kbd_buffer_store_event_hold, gobble_input):
267 (record_asynch_buffer_change) [USABLE_SIGIO]:
268 (store_user_signal_events):
269 No need to mess with signal mask.
270 (gobble_input): If blocking input and there are terminals, simply
271 set pending_signals to 1 and return. All hooks changed to not
272 worry about whether input is blocked.
273 (process_pending_signals): Clear pending_signals before processing
274 them, in case a signal comes in while we're processing.
275 By convention callers now test pending_signals before calling us.
276 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
277 New functions, to support changes to blockinput.h.
278 (handle_input_available_signal): Now extern.
279 (reinvoke_input_signal): Remove. All uses replaced by
281 (quit_count): Now volatile, since a signal handler uses it.
282 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg. All
283 callers changed. Block SIGINT only if not already blocked.
284 Clear sigmask reliably, even if Fsignal returns, which it can.
285 Omit unnecessary accesses to volatile var.
286 (quit_throw_to_read_char): No need to restore sigmask.
287 * keyboard.c (gobble_input, handle_user_signal):
288 * process.c (wait_reading_process_output):
289 Call signal-handling code rather than killing ourselves.
290 * lisp.h: Include <float.h>, for...
291 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
292 (pending_signals): Now volatile.
293 (syms_of_data): Now const if IEEE floating point.
294 (handle_input_available_signal) [USABLE_SIGIO]:
295 (terminate_due_to_signal, record_child_status_change): New decls.
296 * process.c (create_process): Avoid disaster if memory is exhausted
297 while we're processing a vfork, by tightening the critical section
299 (send_process_frame, process_sent_to, handle_pipe_signal)
300 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
302 (send_process): No need for setjmp/longjmp any more, since the
303 SIGPIPE stuff is now gone. Instead, report an error if errno
305 (record_child_status_change): Now extern. PID and W are now args.
306 Return void, not bool. All callers changed.
307 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
308 Remove. All uses removed. This bug should be fixed now in a
310 (wait_for_termination_1): Use waitpid rather than sigsuspend,
311 and record the child status change directly. This avoids the
312 need to futz with the signal mask.
313 (process_fatal_action): Move here from emacs.c.
314 (emacs_sigaction_flags): New function, containing
315 much of what used to be in emacs_sigaction_init.
316 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
317 caught by emacs, to make races less likely.
318 (deliver_process_signal): Rename from handle_on_main_thread.
320 (BACKTRACE_LIMIT_MAX): Now at top level.
321 (thread_backtrace_buffer, threadback_backtrace_pointers):
323 (deliver_thread_signal, deliver_fatal_thread_signal):
324 New functions, for more-accurate delivery of thread-specific signals.
325 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
326 (deliver_arith_signal): Handle in this thread, not
327 in the main thread, since it's triggered by this thread.
328 (maybe_fatal_sig): New function.
329 (init_signals): New arg DUMPING so that we can be more accurate
330 about whether we're dumping. Caller changed.
331 Treat thread-specific signals differently from process-general signals.
332 Block all signals while handling fatal error; that's safer.
333 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
335 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
336 Ignore SIGPIPE unless batch.
337 (emacs_backtrace): Output backtrace for the appropriate thread,
338 which is not necessarily the main thread.
339 * syssignal.h: Include <stdbool.h>.
340 (emacs_raise): New macro.
341 * xterm.c (x_connection_signal): Remove; no longer needed
342 now that we use sigaction.
343 (x_connection_closed): No need to mess with sigmask now.
344 (x_initialize): No need to reset SIGPIPE handler here, since
345 init_signals does this for us now.
347 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
349 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
350 background rect may be larger (Bug#12445).
352 2012-09-23 Chong Yidong <cyd@gnu.org>
354 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
356 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
358 * .gdbinit: Just stop at fatal_error_backtrace.
359 See Stefan Monnier's request in
360 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
361 Remove no-longer-used query of system type.
363 2012-09-22 Chong Yidong <cyd@gnu.org>
365 * search.c (Freplace_match): Doc fix (Bug#12325).
367 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).

376 * dispextern.h (struct image_type): Add new slot, storing a type
377 initialization function.
379 * image.c (define_image_type): Call the image initializer function
380 if it is defined. Arguments and return value changed.
381 (valid_image_p, make_image): Callers changed.
382 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
383 (gif_type, imagemagick_type, svg_type, gs_type): Add
384 initialization functions.
385 (Finit_image_library): Call lookup_image_type.
386 (CHECK_LIB_AVAILABLE): Macro deleted.
387 (lookup_image_type): Call define_image_type here, rather than via
388 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
389 (syms_of_image): Move define_image_type calls for xbm_type and
390 pbm_type to lookup_image_type.
392 2012-09-22 Eli Zaretskii <eliz@gnu.org>
394 * keyboard.c (timer_check_2): Move calculation of 'timers' and
395 'idle_timers' from here ...
396 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
397 lists, to avoid infloops when the timer does something stupid,
398 like reinvoke itself with the same or smaller time-out.
401 2012-09-22 Martin Rudalics <rudalics@gmx.at>
403 * window.c (Fsplit_window_internal): Handle only Qt value of
404 Vwindow_combination_limit separately.
405 (Qtemp_buffer_resize): New symbol.
406 (Vwindow_combination_limit): New default value. Rewrite

411 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
412 the new overlay string. (Bug#10159)
414 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
416 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
417 or that fprintf is async-signal-safe. POSIX doesn't require
420 2012-09-22 Chong Yidong <cyd@gnu.org>
422 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
425 2012-09-22 Kenichi Handa <handa@gnu.org>
427 * composite.c (composition_reseat_it): Handle the case that a
428 grapheme cluster is not covered by a single font (Bug#12352).
430 2012-09-21 Chong Yidong <cyd@gnu.org>
432 * image.c (define_image_type): Avoid adding duplicate types to
433 image_types (Bug#12463). Suggested by Jörg Walter.
435 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
437 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
438 (print_load_command_name): Add case LC_DATA_IN_CODE.
439 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
441 2012-09-21 Glenn Morris <rgm@gnu.org>

444 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
446 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
448 * fileio.c (Ffile_selinux_context): Only call freecon when
449 lgetfilecon succeeded.
450 (Fset_file_selinux_context): Likewise. (Bug#12444)
452 2012-09-21 Eli Zaretskii <eliz@gnu.org>
454 * xdisp.c (try_window_reusing_current_matrix): Under bidi
455 reordering, locate the cursor by calling set_cursor_from_row; if
456 that fails, clear the desired glyph matrix before returning a
457 failure indication to the caller. Fixes leaving garbled display
458 when fast scrolling with a down-key. (Bug#12403)
459 (compute_stop_pos_backwards): Fix a typo that caused crashes while
460 scrolling through multibyte text.
462 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
464 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
465 calling mark_vectorlike since that's the one that marks the window.
466 (mark_discard_killed_buffers): Mark the final cdr.
467 * window.h (struct window): Move prev/next_buffers to the
469 * window.c (make_window): Initialize prev/next_buffers manually.
471 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
473 Omit unused arg EXPECTED from socket hooks.
474 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
475 * nsterm.m (ns_term_init):
476 * termhooks.h (struct terminal.read_socket_hook):
477 * w32inevt.c (w32_console_read_socket):
478 * w32term.c (w32_read_socket):
479 * xterm.c (XTread_socket):
480 Omit unused arg EXPECTED. All callers changed.
481 (store_user_signal_events): Return void, not int, since callers no
482 longer care about the return value. All uses changed.
484 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
486 * w32gui.h (XParseGeometry): Do not declare.
488 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
490 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
491 Ignore 'expected'. See Eli Zaretskii in
492 <http://bugs.gnu.org/12471#8> (last line).
494 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
495 (XParseGeometry): Now static. Substitute extremal values for
496 values that are out of range.
498 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
500 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
502 * nsfns.m (XParseGeometry): Remove.
503 (Fx_create_frame): Call x_set_offset to correctly interpret
506 * frame.c (read_integer, XParseGeometry): Moved from w32xfns.c.
507 (Fx_parse_geometry): If there is a space in string, call
508 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
510 2012-09-17 Eli Zaretskii <eliz@gnu.org>
512 * search.c (scan_buffer): Use character positions in calls to
513 region_cache_forward and region_cache_backward, not byte
514 positions. (Bug#12196)
516 * w32term.c (w32_read_socket): Set pending_signals to 1, like
517 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
519 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
520 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
521 emacs_blocked_malloc, now deleted.
523 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
525 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
526 The workaround was for improving performance on Solaris 2.4, but
527 is getting in the way now. Emacs will still work if someone is
528 still running Solaris 2.4 in a museum somewhere; Sun dropped
529 support for Solaris 2.4 in 2003.
530 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
531 * process.c (create_process) [HAVE_WORKING_VFORK]:
532 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
533 since Emacs no longer uses vfork on that platform.
535 2012-09-17 Glenn Morris <rgm@gnu.org>
537 * emacs.c: Use COPYRIGHT.
539 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
541 Remove configure's --without-sync-input option (Bug#12450).
542 When auditing signal-handling in preparation for cleaning it up,
543 I found that SYNC_INPUT has race conditions and would be a real
544 pain to fix. Since it's an undocumented and deprecated
545 configure-time option, now seems like a good time to remove it.
546 Also see <http://bugs.gnu.org/11080#16>.
547 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
548 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
549 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
551 (check_depth) [XMALLOC_OVERRUN_CHECK]:
552 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
553 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
554 (dont_register_blocks, bytes_used_when_reconsidered)
555 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
556 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
557 [!SYSTEM_MALLOC && !SYNC_INPUT]:
558 Remove. All uses removed.
559 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
560 implementation, one that depends on whether the new macro
561 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
563 * atimer.c (run_timers, handle_alarm_signal):
564 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
565 (handle_async_input, process_pending_signals)
566 (handle_input_available_signal, init_keyboard):
567 * nsterm.m (ns_read_socket):
568 * process.c (wait_reading_process_output):
569 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
570 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
572 * xterm.c (XTread_socket):
574 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
575 * eval.c (handling_signal): Remove. All uses removed.
576 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
577 All uses replaced with the SYNC_INPUT version.
578 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
580 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
583 * font.c (Ffont_shape_gstring): Remove unused local.
585 2012-09-16 Glenn Morris <rgm@gnu.org>
587 * Makefile.in (clean): No longer run nextstep's clean.
589 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
591 (ns-app): Move here from ns.mk, and simplify.
592 (clean): Simplify nextstep entry.
593 * ns.mk: Remove file.
595 2012-09-17 Kenichi Handa <handa@gnu.org>
597 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
598 not covert the last few charactes.
600 2012-09-16 Kenichi Handa <handa@gnu.org>
602 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
603 here, but just check the validity of glyphs in the glyph-string.
605 2012-09-16 Martin Rudalics <rudalics@gmx.at>
607 * window.c (Fwindow_parameter, Fset_window_parameter): Accept
608 any window as argument (Bug#12452).
610 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
612 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
613 to ns_term_init to avoid memory leak.
615 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
616 explicit retain/release.
617 (ns_term_init): Only allow one display. Initialize outerpool and
620 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
622 Port _setjmp fix to POSIXish hosts as well as Microsoft.
623 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
624 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
625 the Microsoft problem in a different way, by altering ../nt/config.nt.
627 2012-09-15 Eli Zaretskii <eliz@gnu.org>
642 * w16select.c: Remove inclusion of setjmp.h, as it is now included
643 by lisp.h. This completes removal of setjmp.h inclusion
644 erroneously announced in the previous commit. (Bug#12446)
646 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
649 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
650 not defined as a macro. The latter happens on MS-Windows.
653 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
655 Port better to POSIX hosts lacking _setjmp (Bug#12446).
656 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
657 Some instances of '#include <setjmp.h>' removed, if the
658 only reason for the instance was because "lisp.h" was included.
659 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
660 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
661 and _longjmp with the new symbols. Emacs already uses _setjmp if
662 available, so this change affects only POSIXish hosts that have
663 sigsetjmp but not _setjmp, such as some versions of Solaris and
664 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
665 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
666 (png_load_body) [HAVE_PNG]:
667 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
668 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
669 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
670 since PNG requires jmp_buf. This is the only exception to the
671 general rule that we now use sys_setjmp and sys_longjmp.
672 This exception is OK since this code does not change the signal
673 mask or longjmp out of a signal handler.
675 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
677 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
678 Include "syssignal.h", for 'main_thread'.
680 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
682 Avoid out-of-range marker position (Bug#12426).
683 * insdel.c (replace_range, replace_range_2): Adjust
684 markers before overlays, as suggested by comments.
685 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
686 Remove redundant check before calling offset_intervals.
688 2012-09-14 Martin Rudalics <rudalics@gmx.at>
690 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
691 current buffer (Bug#12387).
693 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
695 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
697 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
699 Use a more backwards-compatible timer format (Bug#12430).
700 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
701 vector element, not from the 4th, since PSECS is now at the end.
702 (Fcurrent_idle_time): Doc fix.
704 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
706 Function to mark objects and remove killed buffers at once.
707 * alloc.c (discard_killed_buffers): Rename to ...
708 (mark_discard_killed buffers) ... new name. Add marking
709 of remaining objects. Fix comment. Adjust users.
710 (mark_object): Do not touch frame buffer lists here.
711 * frame.c (delete_frame): Reset frame buffer lists here.
713 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
715 Better workaround for GNOME bug when --enable-gcc-warnings.
716 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
717 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
718 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
720 Simplify SIGIO usage (Bug#12408).
721 The code that dealt with SIGIO was crufty and confusing, e.g., it
722 played tricks like "#undef SIGIO" but these tricks were not used
723 consistently. Simplify mostly by not #undeffing standard symbols,
724 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
725 or not as we please) rather than "defined SIGIO" (standard symbol
726 that we probably shouldn't #undef).
727 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
728 Modules that need it can include it.
729 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
730 * dispextern.h (ignore_sigio): New decl.
731 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
732 unconditionally, since it's now a no-op if !USABLE_SIGIO.
733 * emacs.c (shut_down_emacs):
734 * keyboard.c (kbd_buffer_store_event_hold):
735 Use ignore_sigio rather than invoking 'signal' directly.
736 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
738 (FIONREAD, SIGIO): Do not #undef.
739 (tty_read_avail_input): Use #error rather than a syntax error.
740 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
741 for I_PIPE, used by SETUP_SLAVE_PTY.
742 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
743 * sysdep.c (croak): Remove; no longer needed. This bit of
744 temporary code, with Fred N. Fish's comment that it's temporary,
745 has been in Emacs since at least 1992!
746 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
747 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
748 * syssignal.h (croak): Remove decl.
749 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
750 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
751 now that we're termios-only.
752 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
753 * term.c (dissociate_if_controlling_tty): Use #error rather than
756 Work around GCC and GNOME bugs when --enable-gcc-warnings.
757 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
758 to work around GNOME bug 683906.
759 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
760 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
761 This works around GCC bug 54561.
763 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
765 More fixes for 'volatile' and setjmp/longjmp.
766 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
767 * image.c (struct png_load_context) [HAVE_PNG]: New type.
768 (png_load_body) [HAVE_PNG]:
769 (jpeg_load_body) [HAVE_JPEG]:
770 New function, with most of the old parent function's body.
771 (png_load) [HAVE_PNG]:
772 (jpeg_load) [HAVE_JPEG]:
773 Invoke the new function, to avoid longjmp munging our locals.
774 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
775 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
776 longjmp is passed 2, as the C standard doesn't guarantee this.
777 Instead, store the failure code into mgr->failure_code.
779 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
781 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
782 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
783 (syms_of_keyboard): Remove support for unread-command-char.
785 2012-09-12 Eli Zaretskii <eliz@gnu.org>
787 * w32proc.c (sys_kill): If PID is our process ID and the signal is
788 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
789 violation. (Bug#12426)
791 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
793 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
795 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
797 * eval.c: Add `inhibit-debugger'.
798 (Qinhibit_debugger): New symbol.
799 (call_debugger): Bind it instead of Qdebug_on_error.
800 (maybe_call_debugger): Test Vinhibit_debugger.
801 (syms_of_eval): Define inhibit-debugger.
802 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
803 (syms_of_xdisp): Remove inhibit-debug-on-message.
805 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
807 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
808 If a nonvolatile local variable is written before a _longjmp to
809 the frame containing the variable, and is read after the _longjmp,
810 the value read is indeterminate. Some local variables of type
811 'struct handler' and 'struct catchtag' are used in this way, so
812 mark each of their slots as volatile if the slot can be set before
813 _longjmp and read afterwards.
814 * lisp.h (struct handler): var and chosen_clause are now volatile.
815 (struct catchtag): val, next, and pdlcount are now volatile.
817 * bidi.c (bidi_push_it, bidi_pop_it):
818 * fns.c (copy_hash_table):
819 * image.c (define_image_type):
820 * keyboard.c (kbd_buffer_store_event_hold):
821 * process.c (Fprocess_send_eof):
822 * xfaces.c (x_create_gc) [HAVE_NS]:
823 * xgselect.c (xg_select):
824 Prefer assignment to memcpy when either will do.
826 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
827 Use pointer-to-a-pointer to simplify and avoid a NILP check each
828 time an item is removed. No need to mark this function 'inline';
829 the compiler knows better than we do.
831 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
833 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
834 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
835 to change_frame_size (Bug#12388).
836 (windowDidResize:): Pass YES to updateFrameSize.
838 * nsterm.h: Add delay parameter to updateFrameSize.
840 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
842 Discard killed buffers from deleted window and frame objects.
843 This reduces an amount of references to killed buffers and
844 helps GC to reclaim them faster.
845 * alloc.c (discard_killed_buffers): New function.
846 (mark_object): Use it for deleted windows and frames.
847 (mark_object): If symbol's value is set up for a killed buffer
848 or deleted frame, restore it's global binding.
849 * data.c (swap_in_global_binding): Add GC notice.
850 (swap_in_symval_forwarding): Use convenient set_blv_where.
851 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
852 * window.h: ... to here.
854 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
856 Convenient macro to check whether the buffer is live.
857 * buffer.h (BUFFER_LIVE_P): New macro.
858 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
859 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
861 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
863 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
864 composition cases (Bug#12364).
866 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
867 overhang of succeeding glyphs overlapping box cursor.
869 * w32term.c (x_draw_glyph_string): Likewise.
871 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
873 Simplify, document, and port floating-point (Bug#12381).
874 The porting part of this patch fixes bugs on non-IEEE platforms
875 with frexp, ldexp, logb.
876 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
878 * floatfns.c: Simplify discussion of functions that Emacs doesn't
879 support, by removing commented-out code and briefly listing the
880 C89 functions excluded. The commented-out stuff was confusing
881 maintenance, e.g., we thought we needed cbrt but it was commented out.
882 (logb): Remove decl; no longer needed.
883 (isfinite): New macro, if not already supplied.
884 (isnan): Don't replace any existing macro.
885 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
886 are present on all C89 platforms.
887 (Ffrexp): Do not special-case zero, as frexp does the right thing
889 (Flogb): Do not use logb, as it doesn't have the desired meaning
890 on hosts that use non-base-2 floating point. Instead, stick with
891 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
892 frexp, to avoid getting an unspecified result.
894 * xdisp.c (Qinhibit_debug_on_message): Now static.
896 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
898 * nsterm.m (ns_update_begin): Set clip path to whole view by using
899 NSBezierPath (Bug#12131).
901 2012-09-10 Chong Yidong <cyd@gnu.org>
903 * fns.c (Fdelq, Fdelete): Doc fix.
905 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
907 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
908 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
910 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
912 * lisp.h (make_lisp_ptr): New macro to replace XSET.
913 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
916 2012-09-09 Eli Zaretskii <eliz@gnu.org>
918 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
919 left fringe if the window has a left margin. This avoids leaving
920 traces of the cursor because its leftmost pixel is not drawn over.
922 * dispnew.c (update_window_line): When the left margin area of a
923 screen line is updated, set the redraw_fringe_bitmaps_p flag of
924 that screen line. (Bug#12277)
926 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
928 Assume C89 or later for math functions (Bug#12381).
929 This simplifies the code, and makes it a bit smaller and faster,
930 and (most important) makes it easier to clean up signal handling
931 since we can stop worring about floating-point exceptions in
932 library code. That was a problem before C89, but the problem
933 went away many years ago on all practical Emacs targets.
934 * data.c, image.c, lread.c, print.c:
935 Don't include <math.h>; no longer needed.
936 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
937 might be autoconfigured, as that never happens.
939 * doprnt.c (DBL_MAX_10_EXP):
941 Remove. C89 or later always defines these.
942 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
943 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
944 (arith_error, domain_error, domain_error2):
945 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
946 no longer needed -- we simply return what C returns. All uses removed.
947 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
949 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
950 Remove. All uses expanded, as these macros are no longer used
951 more than once and are now more trouble than they're worth.
952 (Ftan): Use tan, not sin / cos.
953 (Flogb): Assume C89 frexp.
954 (fmod_float): Assume C89 fmod.
955 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
956 (init_floatfns): Remove. All uses removed.
958 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
960 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
961 compositeToPoint for OSX < 10.6 (Bug#12390).
963 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
965 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
966 This produces more-accurate results.
968 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
970 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
973 2012-09-08 Chong Yidong <cyd@gnu.org>
975 * syntax.c (Fstring_to_syntax): Doc fix.
977 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
979 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
980 in the internal border.
981 (x_set_window_size): Remove static variables and their usage.
982 (ns_redraw_scroll_bars): Fix NSTRACE arg.
983 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
984 fringe/internal border adjustment (Bug#11052).
985 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
986 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
987 (ns_fix_rect_ibw): Remove.
988 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
989 (ns_dumpglyphs_box_or_relief): Ditto.
990 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
992 (ns_dumpglyphs_image): Ditto.
993 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
995 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
996 their usage. Add fringe_extended_p and its use as in other terms.
997 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
998 scroll bar was removed.
999 (updateFrameSize): New function.
1000 (windowDidResize): Move code to updateFrameSize and call it.
1002 * nsterm.h (EmacsView): Add updateFrameSize.
1004 2012-09-07 Chong Yidong <cyd@gnu.org>
1006 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
1008 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
1010 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1012 More signal-handler cleanup (Bug#12327).
1013 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
1014 Problem introduced when merging patches. Noted by Eli Zaretskii in
1015 <http://bugs.gnu.org/12327#67>.
1016 * floatfns.c: Comment fix.
1017 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
1018 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
1019 and anyway the declaration is harmless even if SIGDANGER is not defined.
1020 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
1021 defined BROKEN_FIONREAD). systty.h formerly did this, but other
1022 source files not surprisingly expected syssignal.h to define, or
1023 not define, SIGIO, and it's cleaner to do it that way, for consistency.
1024 Include <sys/ioctl.h>, for FIONREAD.
1025 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
1026 This eliminates a problem whereby other files mysteriously had
1027 to include "syssignal.h" before including "systty.h" if they
1028 wanted to use "#ifdef SIGIO".
1030 2012-09-07 Eli Zaretskii <eliz@gnu.org>
1032 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
1034 * w32.c (sigemptyset): Empty the set.
1035 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
1037 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
1039 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
1041 * alloc.c (mark_buffer): Revert unsafe marking optimization.
1042 (mark_object): Likewise for frame objects.
1044 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1046 * syssignal.h (handle_on_main_thread): Always declare,
1047 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
1048 This ports to platforms without HAVE_PTHREAD.
1050 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1052 Signal-handler cleanup (Bug#12327).
1053 Emacs's signal handlers were written in the old 4.2BSD style with
1054 sigblock and sigmask and so forth, and this led to some
1055 inefficiencies and confusion. Rewrite these to use
1056 pthread_sigmask etc. without copying signal sets around. Also,
1057 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
1058 'signal', and instead use functions that do not attempt to take
1059 over the system name space. This patch causes Emacs's text
1060 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
1061 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
1062 Do not include <signal.h> or "syssignal.h", as these
1063 modules do not use signals.
1064 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
1065 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
1066 Do not include <signal.h>, as "syssignal.h" does that for us now.
1067 * atimer.c (sigmask_atimers): New function.
1068 (block_atimers, unblock_atimers): New functions,
1069 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
1071 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
1072 no longer needed here.
1073 * emacs.c (main): Inspect existing signal handler with sigaction,
1074 so that there's no need to block and unblock SIGHUP.
1075 * sysdep.c (struct save_signal): New member 'action', replacing
1076 old member 'handler'.
1077 (save_signal_handlers, restore_signal_handlers):
1078 Use sigaction instead of 'signal' to save and restore.
1079 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
1080 New function. All users of 'signal' modified to use set_sighandler
1081 if they're writeonly, and to use sys_signal if they're read+write.
1082 (emacs_sigaction_init, forwarded_signal): New functions.
1083 (sys_signal): Remove. All uses replaced by calls to sigaction
1084 and emacs_sigaction_init, or by direct calls to 'signal'.
1085 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
1086 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
1087 all uses replaced by pthread_sigmask etc. calls.
1088 * syssignal.h: Include <signal.h>.
1089 (emacs_sigaction_init, forwarded_signal): New decls.
1090 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
1091 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
1092 (sigmask, sys_sigmask): Remove; no longer needed.
1093 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
1094 (sigblock, sigunblock, sigfree):
1095 (sigsetmask) [!defined sigsetmask]:
1096 Remove. All uses replaced by pthread_sigmask.
1097 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
1098 no longer need to be replaced, and its typical old uses
1099 are now done via emacs_sigaction_init and sigaction.
1100 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
1101 (sys_sigdel): Remove; unused.
1102 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
1104 2012-09-06 Eli Zaretskii <eliz@gnu.org>
1106 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
1107 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
1109 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1111 Explicitly mark buffer_defaults and buffer_local_symbols.
1112 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
1113 mark_local_symbols here.
1114 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
1115 since special buffers aren't marked here any more.
1116 (allocate_buffer): Chain new buffer with all_buffers here...
1117 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
1119 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
1120 (syms_of_buffer): Remove staticpro of the above.
1121 (init_buffer_once): Set names for buffer_defaults and
1122 buffer_local_symbols.
1124 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1126 Use bool for booleans in font-related modules.
1127 * font.c (font_intern_prop, font_style_to_value)
1128 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
1129 (generate_otf_features, font_check_otf_features, font_check_otf)
1130 (font_match_p, font_list_entities, font_at):
1131 * fontset.c (fontset_id_valid_p, reorder_font_vector
1132 (fontset_find_font, Fset_fontset_font)
1133 (face_suitable_for_char_p) [0]:
1134 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
1135 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
1136 (m17n_flt_initialized, ftfont_shape_by_flt):
1137 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
1138 * nsfont.m (nsfont_draw):
1139 * w32font.c (w32font_draw):
1140 * w32term.c (x_draw_glyphless_glyph_string_foreground):
1141 Use bool for booleans.
1142 * font.h: Adjust to above API changes.
1143 (struct font, struct font_driver, struct font_driver_list):
1144 Use bool for booleans.
1145 (struct font): Remove useless member encoding_type.
1147 * fontset.c, xftfont.c: Omit unnecessary static decls.
1149 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1151 * alloc.c (mark_object): Revert window marking code
1152 since it's unsafe for the Fset_window_configuration.
1154 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1156 Fix race conditions with signal handlers and errno (Bug#12327).
1157 Be more systematic about preserving errno whenever a signal
1158 handler returns, even if it's not in the main thread. Do this by
1159 renaming signal handlers to distinguish between signal delivery
1160 and signal handling. All uses changed.
1161 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
1162 * data.c (deliver_arith_signal): Rename from arith_error.
1163 * dispnew.c (deliver_window_change_signal): Rename from
1164 window_change_signal.
1165 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
1166 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
1167 * keyboard.c (deliver_input_available_signal): Rename from
1168 input_available_signal.
1169 (deliver_user_signal): Rename from handle_user_signal.
1170 (deliver_interrupt_signal): Rename from interrupt_signal.
1171 * process.c (deliver_pipe_signal): Rename from send_process_trap.
1172 (deliver_child_signal): Rename from sigchld_handler.
1173 * atimer.c (handle_alarm_signal):
1174 * data.c (handle_arith_signal):
1175 * dispnew.c (handle_window_change_signal):
1176 * emacs.c (handle_fatal_signal, handle_danger_signal):
1177 * keyboard.c (handle_input_available_signal):
1178 * keyboard.c (handle_user_signal, handle_interrupt_signal):
1179 * process.c (handle_pipe_signal, handle_child_signal):
1180 New functions, with the actual signal-handling code taken from the
1181 original respective signal handlers, sans the sporadic attempts to
1182 preserve errno, since that's now done by handle_on_main_thread.
1183 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
1184 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
1185 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1187 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1188 Move initialization of main_thread to sysdep.c's init_signals.
1189 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
1190 our usage, and simplifies the mainline code.
1191 (record_child_status_change): New static function, as a helper
1192 for handle_child_signal, and with most of the old child handler's
1194 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
1195 (handle_child_signal): Use the above.
1196 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1197 Moved here from emacs.c.
1198 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
1199 code moved here from emacs.c's main function.
1200 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
1201 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
1202 lets callers save and restore errno properly.
1204 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1206 Remove redundant or unused things here and there.
1207 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
1208 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
1209 * editfns.c (Fcompare_buffer_substrings): Likewise.
1210 * frame.h (struct terminal, struct font_driver_list):
1211 Remove redundant declarations.
1212 * window.h (Qleft, Qright): Likewise.
1214 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1216 Do not mark objects from deleted buffers, windows and frames.
1217 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
1218 (mark_object): Likewise for windows and frames.
1220 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1222 * alloc.c (valid_lisp_object_p): Treat killed buffers,
1223 buffer_defaults and buffer_local_symbols as valid objects.
1224 Return special value to denote them.
1226 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1228 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
1229 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
1230 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
1231 (file_name_absolute_p, Fsubstitute_in_file_name):
1232 (check_executable, check_writable, Ffile_accessible_directory_p)
1233 (Fset_file_selinux_context, Fdefault_file_modes)
1234 (Finsert_file_contents, choose_write_coding_system)
1235 (Fwrite_region, build_annotations, a_write, e_write)
1237 * filelock.c (boot_time_initialized, get_boot_time)
1238 (get_boot_time_1, lock_file_1, within_one_second):
1239 * floatfns.c (in_float):
1240 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
1241 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
1242 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
1243 * lisp.h (struct Lisp_Hash_Table.cmpfn):
1244 * window.c (compare_window_configurations):
1245 Use bool for booleans.
1246 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
1247 (Fdefault_file_modes): Now mode_t, not int, for modes.
1248 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
1249 (internal_delete_file): Now returns void, not a (boolean) int,
1250 since nobody was looking at the return value.
1251 * lisp.h, window.h: Adjust to above API changes.
1253 * xdisp.c (set_message): Simplify and reindent last change.
1255 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
1257 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
1259 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
1261 * eval.c (call_debugger): Make the function non-static so that we
1262 can call it from set_message.
1264 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
1265 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
1267 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1269 Give more-useful info on a fatal error (Bug#12328).
1270 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
1271 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
1272 of doing the work ourselves.
1273 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
1274 do most of the work.
1275 (fatal_error_backtrace): New function, taken from the guts
1276 of the old fatal_error_signal, but with a new option to output
1278 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
1279 info about the signal than just its number.
1280 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
1281 * sysdep.c: Include <execinfo.h>
1282 (emacs_backtrace): New function, taken partly from the previous
1283 code of the 'die' function.
1284 (emacs_abort): Call fatal_error_backtrace rather than abort.
1286 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
1288 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
1289 eager (load-time) macro-expansion.
1290 * lisp.mk (lisp): Add macroexp.
1292 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1294 Simplify redefinition of 'abort' (Bug#12316).
1295 Do not try to redefine the 'abort' function. Instead, redo
1296 the code so that it calls 'emacs_abort' rather than 'abort'.
1297 This removes the need for the NO_ABORT configure-time macro
1298 and makes it easier to change the abort code to do a backtrace.
1299 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
1300 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
1301 Remove; sysdep.c's emacs_abort now takes its place.
1302 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
1303 'abort' changed to use 'emacs_abort'.
1304 * msdos.c (dos_abort) [defined abort]: Remove; not used.
1305 (abort) [!defined abort]: Rename to ...
1306 (emacs_abort): ... new name.
1307 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
1308 the place of the old 'abort' in emacs.c.
1309 * w32.c, w32fns.c (abort): Do not #undef.
1310 * w32.c (emacs_abort): Rename from w32_abort.
1312 2012-09-04 Eli Zaretskii <eliz@gnu.org>
1314 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
1315 offsets[j].dv, since the y axis of the screen coordinates points
1316 down, while the y axis of the font definition coordinates points
1317 up. This fixes display of Arabic diacritics such as KASRA and
1318 KASRATAN. (Bug#11860)
1320 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1322 Be more systematic about _setjmp vs setjmp.
1323 * alloc.c (test_setjmp, mark_stack):
1324 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
1325 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
1326 (png_load, my_error_exit, jpeg_load):
1327 * process.c (send_process_trap, send_process):
1328 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
1329 The underscored versions are up to 30x faster on some hosts.
1330 Formerly, the code used setjmp+longjmp sometimes and
1331 _setjmp+_longjmp at other times, with no particular reason to
1332 prefer setjmp+longjmp.
1334 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
1336 Fix minor problem found by static checking.
1337 * buffer.c (Fdelete_all_overlays): Return nil.
1339 2012-09-03 Martin Rudalics <rudalics@gmx.at>
1341 * buffer.c (Fdelete_all_overlays): New function.
1343 2012-09-03 Chong Yidong <cyd@gnu.org>
1345 * gtkutil.c: Add extern decl for Qxft.
1347 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
1349 * emacs.c, eval.c: Use bool for boolean.
1350 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
1351 (malloc_using_checking) [DOUG_LEA_MALLOC]:
1352 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
1353 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
1354 (main, decode_env_path, Fdaemon_initialized):
1355 * eval.c (call_debugger, Finteractive_p, interactive_p):
1356 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
1357 (maybe_call_debugger, Fbacktrace):
1358 * process.c (read_process_output, exec_sentinel):
1359 Use bool for booleans.
1360 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
1361 All callers changed.
1362 * eval.c (interactive_p): Omit always-true boolean argument
1363 EXCLUDE_SUBRS_P. All callers changed.
1364 * dispextern.h, lisp.h: Reflect above API changes.
1365 * firstfile.c (dummy): Use the address of 'main', whose signature

1373 REDISPLAYING_P when unwinding, instead of saving its previous,
1374 always-false value and then restoring it.
1376 Clean up some extern decls.
1377 Mostly, this hoists extern decls out of .c files and into .h files.
1378 That way, we're more likely to catch errors if the interfaces change.

1464 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
1465 more than one grapheme cluster passed to the shaper: compute the
1466 offset adjustment values separately for each cluster. (Bug#11860)
1468 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1469 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1470 about implicit conversions from integer to pointer.
1472 2012-09-01 Daniel Colascione <dancol@dancol.org>
1474 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

1528 window system declarations.
1530 * frame.h: Move common functions here: set_frame_menubar,
1531 x_set_window_size, x_sync, x_get_focus_frame,
1532 x_set_mouse_position, x_set_mouse_pixel_position,
1533 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

1620 Add window_closed and button_values. Add void as return value for
1621 add(Button|String|Split). addButton takes int instead of Lisp_Object.
1622 Add process_dialog as new member.

1814 (load_charset_map_from_file, map_charset_chars)
1815 (Fdefine_charset_internal, define_charset_internal)
1816 (Fdeclare_equiv_charset, find_charsets_in_text)
1817 (Ffind_charset_region, char_charset, Fiso_charset):
1818 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
1819 (sub_char_table_set, sub_char_table_set_range)
1820 (char_table_set_range, optimize_sub_char_table)
1821 (map_sub_char_table):
1822 Use bool for boolean.
1823 * character.c (str_to_unibyte): Omit last boolean argument; it was
1824 always 0. All callers changed.
1825 * character.h, charset.h: Adjust to match previous changes.
1826 * character.h (char_printable_p): Remove decl of nonexistent function.
1827 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
1828 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
1829 are all boolean, so make them single-bit bitfields.
1831 * lisp.h (ASET): Remove attempt to detect side effects.
1832 It was meant to be temporary and it often doesn't work,
1833 because when IDX has side effects the behavior of IDX==IDX
1834 is undefined. See Stefan Monnier in
1835 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
1837 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
1839 * lisp.h (functionp): New function (extracted from Ffunctionp).
1840 (FUNCTIONP): Use it.
1841 * eval.c (Ffunctionp): Use it.
1843 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1845 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
1846 as that's faster and simpler than static storage. Don't bother
1847 with the g_main_context_query overhead if g_main_context_pending
1848 says no events are pending.
1849 (gfds, gfds_size): Remove these static vars.
1850 (xgselect_initialize): Remove; no longer needed.
1851 All uses and decls removed.
1853 * emacs.c (fatal_error_signal_hook): Remove.
1854 All uses removed. This leftover from old code was always 0.
1856 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
1857 * casefiddle.c (casify_object, casify_region):
1858 * casetab.c (set_case_table):
1859 * category.c, category.h (word_boundary_p):
1860 * category.h (CHAR_HAS_CATEGORY):
1861 Use bool for booleans, instead of int.
1863 2012-08-25 Eli Zaretskii <eliz@gnu.org>
1865 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
1867 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1869 On assertion failure, print backtrace if available.
1870 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1871 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1872 * Makefile.in (LIB_EXECINFO): New macro.
1875 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1876 * bytecode.c (exec_byte_code):
1877 * callint.c (check_mark, Fcall_interactively):
1878 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1879 (getenv_internal, sync_process_alive, call_process_exited):
1880 * lisp.h (USE_SAFE_ALLOCA):
1881 Use bool for booleans, instead of int.
1882 * lisp.h, process.h: Adjust prototypes to match above changes.
1883 * callint.c (Fcall_interactively): Don't assume the mark's
1884 offset fits in 'int'.
1886 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1888 * buffer.c, buffer.h: Use bool for boolean.
1889 * buffer.c (reset_buffer_local_variables)
1890 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1891 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
1892 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
1893 (overlay_touches_p, overlay_strings, Foverlay_put)
1894 (report_overlay_modification, call_overlay_mod_hooks):
1895 (mmap_enlarge, mmap_set_vars):
1896 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1897 Use bool for booleans, instead of int.
1898 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1899 since the 1-or-0 return value is always ignored anyway.
1900 (mmap_initialized_p):
1901 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1902 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1904 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1906 * bidi.c: Use bool for boolean.
1907 This is a bit more readable, and makes the text segment of bidi.o
1908 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1909 Presumably it's faster too.
1910 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1912 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1913 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1914 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1915 (bidi_explicit_dir_char, bidi_level_of_next_char)
1916 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1917 Use bool for booleans, instead of int.
1918 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1919 (bidi_unshelve_cache): Adjust decls to match code.
1921 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1923 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1926 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1928 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1929 * atimer.h: Include <stdbool.h>.
1931 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1933 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1934 compile time tests instead of run time tests on systems that do
1936 (FRAME_MAC_P): Remove leftover from deleted code.
1937 * frame.c (syms_of_frame): Remove leftover from deleted code.
1939 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
1941 * nsterm.m (insertText:): Don't clear modifiers if code is space.
1943 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1945 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1946 Otherwise, the compiler complains about (A?B:C) where B is void
1947 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1948 (fontset_add): Return void, for FONTSET_ADD.
1950 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1952 * alloc.c: Use bool for booleans.
1953 (gc_in_progress, abort_on_gc)
1954 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1955 (dont_register_blocks) [GC_MALLOC_CHECK]:
1956 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1957 (check_string_bytes, make_specified_string, memory_full)
1958 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1959 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1960 (mark_stack, valid_pointer_p, make_pure_string)
1961 (Fgarbage_collect, survives_gc_p, gc_sweep):
1962 Use bool for booleans, instead of int.
1963 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1964 Remove unused local.
1965 * alloc.c (PURE_POINTER_P):
1966 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1967 * editfns.c (Fformat):
1968 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1970 * fns.c (sweep_weak_table):
1971 * lisp.h (suppress_checking, push_message, survives_gc_p)
1972 (make_pure_string, gc_in_progress, abort_on_gc):
1973 * lread.c (readchar, read1):
1974 * print.c (Fprin1_to_string):
1975 * xdisp.c (push_message):
1976 Use bool for booleans affected directly or indirectly by
1979 Make recently-introduced setters macros.
1980 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1981 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1982 (set_fontset_default, set_fontset_fallback): Rename from their
1983 upper-case counterparts, and make them functions rather than macros.
1984 This is more consistent with the other recently-introduced setters.
1985 These don't need to be inline, since they're local.
1987 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1989 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1990 the loop (Bug#12247).
1992 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1994 * lisp.h (vcopy): Use memcpy rather than our own loop.
1995 This fixes a performance regression introduced by the recent
1996 addition of vcopy. This means 'vcopy' will need to be modified
1997 for a copying collector, but that's OK. Also, tighten the
1998 checking in the assertion.
2000 2012-08-21 Eli Zaretskii <eliz@gnu.org>
2002 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
2003 components for RTL text (Bug#11860). Adjust X-OFFSET of each
2004 non-base glyph for the width of the base character, according to
2005 what x_draw_composite_glyph_string_foreground expects.
2006 Generate WADJUST value according to composition_gstring_width's
2007 expectations, to produce correct width of the composed character.
2008 Reverse the sign of the DU offset produced by ScriptPlace.
2010 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2012 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
2014 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2016 Avoid direct writes to contents member of struct Lisp_Vector.
2017 * lisp.h (vcopy): New function to copy data into vector.
2018 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
2019 * fns.c (Ffillarray): Use ASET.
2020 * keyboard.c (timer_check_2): Use AREF and ASET.
2021 (append_tool_bar_item, Frecent_keys): Use vcopy.
2022 * lread.c (read_vector): Use ASET.
2023 * msdos.c (Frecent_doskeys): Use vcopy.
2024 * xface.c (Finternal_copy_lisp_face): Use vcopy.
2025 (Finternal_merge_in_global_face): Use ASET and vcopy.
2026 * xfont.c (xfont_list_pattern): Likewise.
2028 2012-08-21 Martin Rudalics <rudalics@gmx.at>
2030 * window.c (Fwindow_point): For the selected window always return
2031 the position of its buffer's point.
2032 (Fset_window_point): For the selected window always go in its
2033 buffer to the specified position.
2035 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2037 Setter macros for fontsets.
2038 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
2039 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
2040 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
2043 2012-08-20 Glenn Morris <rgm@gnu.org>
2045 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
2046 Don't assume that `ln -f' works.
2048 2012-08-20 Eli Zaretskii <eliz@gnu.org>
2050 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
2051 and later about non-assignments with no effect. See discussion at
2052 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
2055 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2057 Inline setter functions for Lisp_Objects slots of struct specbinding.
2058 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
2061 2012-08-20 Martin Rudalics <rudalics@gmx.at>
2063 * window.c (select_window): Always make selected window's buffer
2066 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2068 Use AREF and ASET for docstrings of category tables.
2069 * category.h (CATEGORY_DOCSTRING): Use AREF.
2070 (SET_CATEGORY_DOCSTRING): Use ASET.
2071 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
2073 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2075 Inline setter functions for hash table members.
2076 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
2077 (set_hash_hash, set_hash_index): Rename with _slot suffix.
2078 (set_hash_key_and_value, set_hash_index, set_hash_next)
2079 (set_hash_hash): New functions.
2080 * charset.c, fns.c: Adjust users.
2082 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2084 Inline getter and setter functions for per-buffer values.
2085 * buffer.h (per_buffer_default, set_per_buffer_default)
2086 (per_buffer_value, set_per_buffer_value): New functions.
2087 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
2088 * buffer.c, data.c: Adjust users.
2090 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
2092 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
2094 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
2096 Rely on <config.h> + <unistd.h> to declare 'environ',
2097 as gnulib does this if the system doesn't.
2098 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
2099 Remove declaration. MS-Windows declares it on stdlib.h which is
2100 included by conf_post.h.
2101 * emacs.c (environ) [DOUG_LEA_MALLOC]:
2102 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
2103 * vm-limit.c: Include <unistd.h>, for 'environ'.
2105 * unexaix.c, unexcoff.c: Include "mem-limits.h".
2106 (start_of_data): Remove decl; mem-limits.h provides it.
2108 * xdisp.c (handle_invisible_prop): Make it a bit faster
2109 and avoid a gcc -Wmaybe-uninitialized diagnostic.
2111 2012-08-19 Chong Yidong <cyd@gnu.org>
2113 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
2116 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
2118 * .gdbinit: Use call instead of set when calling a function in the
2121 * data.c (set_internal): Don't use set_blv_found.
2122 (Fkill_local_variable): Likewise.
2124 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
2126 * nsfont.m (ns_ascii_average_width): Ensure the string
2127 ascii_printable is initialized with a null-terminated character
2128 array. Otherwise, it can contain undesired extra characters.
2130 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2132 port new setting code to Sun C 5.8 2005/10/13
2133 * chartab.c, lisp.h (char_table_set, char_table_set_range):
2134 Return void, not Lisp_Object. Otherwise, the compiler
2135 complains about (A?B:C) where B is void and C is Lisp_Object
2136 when compiling CHAR_TABLE_SET, due to the recent change to
2137 the API of sub_char_table_set_contents.
2139 2012-08-18 Chong Yidong <cyd@gnu.org>
2141 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
2142 for the string case (Bug#3874).
2144 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2146 * buffer.h (BSET): Remove (Bug#12215).
2147 Replace all uses with calls to new setter functions.

2216 New setter functions.
2218 * termhooks.h (TSET): Remove (Bug#12215).
2219 Replace all uses with calls to new setter functions.
2220 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
2221 (TERMHOOKS_INLINE): New macro.
2222 (tset_charset_list, tset_selection_alist): New setter functions.
2223 * terminal.c (TERMHOOKS_INLINE):
2224 Define to EXTERN_INLINE, so that the corresponding functions
2225 are compiled into code.
2226 (tset_param_alist): New setter function.
2228 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
2230 * keyboard.h (KSET): Remove (Bug#12215).

2974 value of EMACSLOADPATH, as it is no longer needed.
2975 (check_windows_init_file): Now external, not static.

3026 * alloc.c (record_xmalloc): New function.
3027 * lisp.h (record_xmalloc): New decl.
3028 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
3029 more like a function. This is because the pointer cast is not
3030 needed. All uses changed.
3031 * print.c (print_string, print_error_message): Avoid length recalc.
3033 Improve fix for macroexp crash with debugging (Bug#12118).
3034 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to

3068 with addition of handling of symlinks and support for 'lstat'.
3069 If possible, get file's attributes and security information by
3070 handle, not by name. Produce S_IFLNK bit for symlinks, when
3071 called from 'lstat'.
3072 (stat, lstat): New functions, call 'stat_worker'.
3073 (symlink, readlink, careadlinkat): Rewritten to create and resolve
3074 symlinks when the underlying filesystem supports them.

3079 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
3080 checking subscripts; problem introduced with the recent
3081 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
3082 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
3083 since it's used in non-static inline functions now.
3085 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

3580 is an integer literal.
3581 (xgetint): Simplify expression.
3582 * alloc.c (gdb_make_enums_visible): New constant. This ports to
3583 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
3584 Zaretskii in <http://bugs.gnu.org/12036#13>.
3585 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
3586 needed now that we have gdb_make_enums_visible.
3587 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
3588 (enum enum_USE_LSB_TAG):
3589 New enum types, packaging up enums that need to be exported to GDB.
3591 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

3607 * xdisp.c (syms_of_xdisp): Likewise.
3608 * xfns.c (syms_of_xfns): Likewise.
3610 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3612 Fast save_excursion_save and save_excursion_restore.
3613 * lisp.h (struct Lisp_Excursion): New data type.
3614 (PVEC_EXCURSION): New pseudovector type.
3615 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
3616 to deal with it. Adjust comments.
3617 (init_marker, attach_marker): New prototype.
3618 (unchain_marker): Adjust prototype.
3619 * marker.c (attach_marker): Change to global.

3627 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
3629 Fix export of symbols to GDB (Bug#12036).
3630 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
3631 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
3632 emacs.c, as this is a more-suitable home. Had this been done earlier
3633 the fix for 12036 would have avoided some of the problems noted in
3634 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
3635 would have been more obvious.
3636 * emacs.c: Do not include <verify.h>; no longer needed.
3637 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
3638 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
3639 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3640 Remove; now done in lisp.h.
3641 * lisp.h (PUBLISH_TO_GDB): New macro.

3643 (DATA_SEG_BITS): Use it.
3644 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
3645 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3646 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3647 not be usable in #if. This simplifies things.
3649 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
3651 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
3653 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
3655 Simplify export of symbols to GDB (Bug#12036).
3656 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3657 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3658 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3659 Adjust to changes in lisp.h and emacs.c, by using
3660 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
3661 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
3662 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
3663 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
3664 instead of gdb_valbits.
3665 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
3666 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
3667 instead of gdb_array_mark_flag.
3668 (xboolvector): Get size from $->size, not $->header.size.
3669 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
3670 (xreload, hook-run, hookpost-run): Remove.
3671 * emacs.c: Include <verify.h>.
3672 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
3673 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
3675 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
3676 (gdb_USE_LSB_TAG): New enum constants.
3677 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3678 Also define these as enum constants, so they're visible to GDB.
3679 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
3680 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
3681 as constants, so they're visible to GDB.
3682 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
3683 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
3684 Now enum constants, not macros, so they're visible to GDB.
3685 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
3686 more convenient now. All uses changed.
3687 (VALMASK) [USE_LSB_TAG]: Also define in this case.
3688 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
3690 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

3697 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
3698 add argument, tune behavior, and adjust all callers.
3700 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
3702 Use typedef for EMACS_INT, EMACS_UINT.
3703 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
3704 than macros. This simplifies debugging in the usual case, since
3705 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
3706 and it allows expressions involving EMACS_INT casts.
3707 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
3709 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

3719 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
3721 Adjust buffer text indirection counters at the end of Fkill_buffer.
3722 * buffer.c (Fkill_buffer): Adjust indirection counters when the
3723 buffer is definitely dead. This should really fix an issue reported
3724 by Christoph Scholtes again. (Bug#12007).
3725 (init_buffer_once): Initialize indirection counters of
3726 buffer_defaults and buffer_local_symbols (for sanity and safety).
3728 2012-07-24 Eli Zaretskii <eliz@gnu.org>
3730 * xdisp.c (init_iterator): Don't compute dimensions of truncation
3731 and continuation glyphs on tooltip frames, leave them at zero.
3732 Avoids continued lines in tooltips. (Bug#11832)
3734 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

3759 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3761 Swap buffer text indirection counters in Fbuffer_swap_text.
3762 * buffer.c (Fbuffer_swap_text): Swap indirections too.
3763 This avoids crash reported by Christoph Scholtes at
3764 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
3766 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
3768 * nsmenu.m (Popdown_data): New struct.

3773 and autorelease them. Also autorelease img and matrix (Bug#12005).
3774 (dealloc): Remove (Bug#12005).

3791 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
3793 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
3794 as it's limited by the amount of memory, not by INT_MAX.
3796 2012-07-21 Eli Zaretskii <eliz@gnu.org>
3798 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
3799 in special-event-map. See the discussion at

3858 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
3859 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
3860 Adjust users accordingly.
3861 * font.h (font_open_by_name): Adjust prototype.
3863 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

3880 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
3881 'for_each_per_buffer_object_at'.
3882 All uses changed. It's better to use upper-case for macros that
3883 cannot be implemented as functions, to give the reader a clue
3884 that they're special.
3886 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>

3932 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
3934 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
3936 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
3937 when invoking (make-bool-vector N t) and N is a positive

3945 padding before the data member of a bool vector.
3946 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
3947 than doing the check by hand with an abort ().
3949 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3951 * eval.c (Fdefvar): Don't check constants since we only set the var if
3952 it's not yet defined anyway (bug#11904).
3954 * lisp.h (last_undo_boundary): Declare new var.
3955 * keyboard.c (command_loop_1): Set it.
3956 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
3957 were auto-added by the command loop (bug#11774).
3959 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
3961 * w32font.c (Qsymbol): Remove local definition.

4469 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
4470 function attribute, so we only use it if it exists in the
4473 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
4475 Avoid call to strlen in fast_c_string_match_ignore_case.
4476 * search.c (fast_c_string_match_ignore_case): Change to use
4477 length argument. Adjust users accordingly.
4478 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
4480 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

4521 Remove "#define unix" that is no longer needed (Bug#11905).
4522 * s/aix4-2.h (unix): Remove; no longer needed.
4524 EMACS_TIME simplification (Bug#11875).
4525 This replaces macros (which typically do not work in GDB)
4526 with functions, typedefs and enums, making the code easier to debug.
4527 The functional style also makes code easier to read and maintain.
4528 * systime.h: Include <sys/time.h> on all hosts, not just if
4529 WINDOWSNT, since 'struct timeval' is needed in general.
4530 (EMACS_TIME): Now a typedef, not a macro.
4531 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
4533 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

4536 (EMACS_TIME_LE): Now functions, not macros.
4537 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
4538 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
4539 which are not functions. All uses rewritten to use:
4540 (make_emacs_time): New function.
4541 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
4542 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4543 not functions. All uses rewritten to use the following, respectively:
4544 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
4545 (add_emacs_time, sub_emacs_time): New functions.
4546 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
4547 * fileio.c (Fcopy_file):
4548 * xterm.c (XTflash): Get the current time closer to when it's used.
4549 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

4556 * frame.c (Fmake_terminal_frame):
4557 * gtkutil.c (get_utf8_string):
4559 * nsmenu.m (ns_update_menubar):
4560 * regex.c (regerror):
4561 Prefer memcpy to strncpy and strncat when either will do.
4562 * fileio.c (Fsubstitute_in_file_name):
4563 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
4564 (menu_separator_name_p):
4565 * nsmenu.m (ns_update_menubar):
4566 Prefer memcmp to strncmp when either will do.
4567 * nsterm.m: Include <ftoastr.h>.
4569 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
4570 Prefer snprintf to strncpy.
4571 * nsterm.m (ns_term_init):
4572 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4573 * nsterm.m (ns_term_init):
4574 Avoid the need for strncpy, by using build_string or
4575 make_unibyte_string directly. Use dtoastr, not snprintf.
4576 * process.c (Fmake_network_process): Diagnose service names that
4577 are too long, rather than silently truncating them or creating
4578 non-null-terminated names.
4579 (Fnetwork_interface_info): Likewise, for interface names.
4580 * sysdep.c (system_process_attributes) [GNU_LINUX]:
4581 Prefer sprintf to strncat.
4582 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
4583 Prefer vsnprintf to vsprintf + strncpy.
4585 2012-07-10 Glenn Morris <rgm@gnu.org>
4587 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
4588 Clarify fallback case.
4590 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4592 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
4593 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
4594 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
4595 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
4596 where argument type is known to be a Lisp_Cons.
4598 2012-07-10 Tom Tromey <tromey@redhat.com>
4600 * bytecode.c (BYTE_CODE_THREADED): New macro.
4601 (BYTE_CODES): New macro. Replaces all old byte-code defines.
4602 (enum byte_code_op): New type.

4608 Optimize pure C strings initialization.
4609 * lisp.h (make_pure_string): Fix prototype.
4610 (build_pure_c_string): New function, defined as static inline. This
4611 provides a better opportunity to optimize away calls to strlen when
4612 the function is called with compile-time constant argument.
4613 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
4614 argument, adjust users accordingly. Use build_pure_c_string where
4616 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
4617 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
4618 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
4620 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4622 Avoid calls to strlen in miscellaneous functions.
4623 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
4624 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
4625 * lread.c (openp): Likewise.
4627 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4629 Avoid calls to strlen in path processing functions.
4630 * fileio.c (file_name_as_directory): Add comment. Change to add
4631 srclen argument and return the length of result. Adjust users
4633 (directory_file_name): Fix comment. Change to add srclen argument,
4634 swap 1st and 2nd arguments to obey the common convention.
4635 Adjust users accordingly.
4636 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
4638 2012-07-10 Glenn Morris <rgm@gnu.org>
4640 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
4641 Move PENDING_OUTPUT_COUNT definition to configure.
4643 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
4644 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
4645 * s/gnu.h (DATA_START): Move definitions to configure.
4647 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
4648 We include usg5-4-common.h, which defines them both.
4650 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
4651 O_RDONLY already includes it).
4653 Stop ns builds setting the EMACSLOADPATH environment variable.
4654 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4655 Now it does not set EMACSLOADPATH, just returns the load-path string.
4656 * nsterm.h: Update accordingly.
4657 * lread.c [HAVE_NS]: Include nsterm.h.
4658 (init_lread) [HAVE_NS]: Use ns_load_path.
4659 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
4661 2012-07-09 Glenn Morris <rgm@gnu.org>
4663 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
4664 since the included bsd-common.h does so.
4666 Stop ns builds setting the EMACSPATH environment variable.
4667 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
4668 (ns_init_paths): Do not set EMACSPATH.
4669 * nsterm.h (ns_exec_path): Add it.
4670 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
4673 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
4675 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
4677 * process.c (wait_reading_process_output): 'waitchannels' was unset
4678 when read_kbd || !NILP (wait_for_cell); fix this.
4680 Add GCC-style 'const' attribute to functions that can use it.
4681 * character.h (char_resolve_modifier_mask):
4682 * keyboard.h (make_ctrl_char):
4683 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
4684 (init_character_once, next_almost_prime, init_fns, init_image)
4685 (flush_pending_output, init_sound):
4686 * mem-limits.h (start_of_data):

4690 Declare the dummy function with ATTRIBUTE_CONST.
4691 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
4692 Add decls with ATTRIBUTE_CONST.
4694 Minor improvements to make_formatted_string.
4695 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
4696 where int is good enough, as vsprintf returns an int.
4697 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
4699 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4701 Use make_formatted_string to avoid double length calculation.
4702 * lisp.h (make_formatted_string): New prototype.
4703 * alloc.c (make_formatted_string): New function.
4704 * buffer.c (Fgenerate_new_buffer_name): Use it.
4705 * dbus.c (syms_of_dbusbind): Likewise.

4708 * frame.c (make_terminal_frame, set_term_frame_name)
4709 (x_report_frame_params): Likewise.
4710 * image.c (gs_load): Likewise.
4711 * minibuf.c (get_minibuffer): Likewise.
4712 * msdos.c (dos_set_window_size): Likewise.
4713 * process.c (make_process): Likewise.

4724 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
4726 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4728 Move marker debugging code under MARKER_DEBUG.
4729 * marker.c (MARKER_DEBUG): Move marker debugging code under
4730 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4731 for bootstrap with --enable-checking (~3x slowdown reported
4732 by Juanma Barranquero <lekktu@gmail.com>).
4733 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4735 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4737 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
4738 See <http://bugs.gnu.org/11825#29>.
4740 2012-07-08 Eli Zaretskii <eliz@gnu.org>
4742 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4743 has no font, use the frame's font. (Bug#11813)
4744 (display_line): Add commentary about displaying truncation glyphs
4746 (produce_special_glyphs): Move here from term.c.
4748 * term.c (produce_special_glyphs): Move to xdisp.c.
4750 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4753 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4755 * xdisp.c (display_line): Avoid warning about implicit declaration
4758 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4760 * lisp.h: Remove empty conditional.
4762 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4764 * lread.c (load_path_check): Now static.
4766 Fix some minor --with-ns problems found by static checking.
4767 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
4768 (x_set_font) [!HAVE_X_WINDOWS]:
4769 * image.c (xpm_load_image) [HAVE_NS]:
4770 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4771 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4772 Remove unused local.
4773 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
4774 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
4775 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
4776 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
4777 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
4778 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
4779 Fix pointer signedness problem.
4780 * xfaces.c (FRAME_X_FONT_TABLE):
4781 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
4783 2012-07-07 Glenn Morris <rgm@gnu.org>
4785 * lread.c (load_path_check): New function, split from init_lread.
4786 (init_lread): Reorganize. Motivation:
4787 If EMACSLOADPATH is set, check/warn about that rather than the
4788 defaults, which we are not going to use. Hence we can remove
4789 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4790 Don't warn if site-lisp directories are missing.
4791 If not installed, start from a blank load-path, since
4792 PATH_LOADSEARCH refers to the eventual installation directories.
4794 2012-07-07 Eli Zaretskii <eliz@gnu.org>
4796 Support truncation and continuation glyphs on GUI frames, when
4797 fringes are disabled. (Bug#11832)
4798 * xdisp.c (init_iterator): Get dimensions of truncation and
4799 continuation glyphs even if on GUI frames.
4800 Adjust it->last_visible_x on GUI frames when the left or right fringes,
4801 or both, are absent.
4802 (start_display, move_it_in_display_line_to): Handle the case of a
4803 GUI frame without a fringe to display continuation or truncation
4805 (insert_left_trunc_glyphs): Support GUI frames: make sure
4806 truncation glyphs overwrite enough glyphs from the current line to
4807 have sufficient space in pixels.
4808 (display_line): Support truncation and continuation glyphs on GUI
4809 frames. If some spare pixels are left on the line after inserting
4810 the truncation glyphs, fill that space with a stretch glyph of a
4811 suitably computed width.
4813 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4814 produce_glyphs, to support GUI sessions.
4816 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4818 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4820 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4822 Do not require float-time's arg to fit in time_t (Bug#11825).
4823 This works better on hosts where time_t is unsigned, and where
4824 float-time is applied to the (negative) difference between two times.
4825 * editfns.c (decode_time_components): Last arg is now double *,
4826 not int *, and means to store all the result as a double, without
4827 worrying about whether the seconds part fits in time_t.
4828 All callers changed.
4829 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4830 All callers changed.
4831 (Ffloat_time): Do not fail merely because the specified time falls
4832 outside of time_t range.
4834 2012-07-07 Glenn Morris <rgm@gnu.org>
4836 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

4840 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
4842 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
4843 Update dependencies.
4845 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
4847 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4849 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
4850 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
4851 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
4852 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
4853 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
4854 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
4856 * xfont.c (compare_font_names): Redo to omit the need for casts.
4858 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4860 * xfns.c (Fx_change_window_property): Doc fix.
4861 * w32fns.c (Fx_change_window_property): Doc fix.
4863 * w32fns.c (Fx_window_property): Accept the same arguments as the
4864 X Windows version. Doc fix.
4865 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4867 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4868 Eli Zaretskii <eliz@gnu.org>
4870 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4871 Windows-specific code from nt/config.nt moved here.
4872 Obsolete settings removed.
4874 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4876 * process.c: Avoid unnecessary calls to gettime.
4877 (wait_reading_process_output): Don't get the time of day
4878 when gobbling data immediately and not waiting, as there's no need
4879 for it in that case. This removes a FIXME.
4881 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4883 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4884 is defined (Bug#11768).
4886 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4888 Fix marker debugging code.
4889 * marker.c (byte_char_debug_check): Do not perform the check
4890 if buffer is not multibyte.
4891 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4892 Call byte_char_debug_check with correct arguments.
4894 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4896 Compile marker debugging code only if ENABLE_CHECKING is defined.
4897 * marker.c (byte_char_debug_check, count_markers):
4898 Use only if ENABLE_CHECKING is defined.
4899 (byte_debug_flag): Remove.
4900 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4901 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4903 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4905 Avoid code repetition in marker-related functions.
4906 * marker.c (attach_marker): New function.
4907 (Fset_marker, set_marker_restricted, set_marker_both)
4908 (set_marker_restricted_both): Use it.
4909 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4910 Consistently rename charno to charpos.
4911 (marker_position): Add eassert.
4912 (marker_byte_position): Convert to eassert.

4918 * marker.c (unchain_marker): Simplify. Fix comments.
4920 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4922 Introduce fast path for the widely used marker operation.
4923 * alloc.c (build_marker): New function.
4924 * lisp.h (build_marker): New prototype.
4925 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
4926 * composite.c (autocmp_chars): Likewise.
4927 * editfns.c (buildmark): Remove.
4928 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
4929 (save_restriction_save): Use build_marker.
4930 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
4931 * window.c (save_window_save): Likewise.
4933 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4935 Do not use Fdelete_overlay in delete_all_overlays
4936 to avoid redundant calls to unchain_overlay.
4937 * buffer.c (drop_overlay): New function.
4938 (delete_all_overlays, Fdelete_overlay): Use it.
4939 * minibuf.c (get_minibuffer): Fix comment.
4941 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4943 Port to OpenBSD 5.1 amd64.
4944 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4945 This is needed for OpenBSD, and should be harmless on all BSD systems.
4946 Also, include <sys/sysctl.h>, as it should be available on all
4947 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4948 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4949 use p_pid member, not kp_proc.pid.
4951 2012-07-06 Glenn Morris <rgm@gnu.org>
4953 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4955 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4957 More xmalloc and related cleanup.
4958 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

4965 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
4966 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4968 Omit needless casts involving void * pointers and allocation.
4969 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4970 as the former is more robust if P's type is changed.
4971 Prefer xzalloc to xmalloc + memset 0.
4972 Simplify malloc-or-realloc to realloc.
4973 Don't worry about xmalloc returning a null pointer.
4974 Prefer xstrdup to xmalloc + strcpy.
4975 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4977 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4978 alloca of a constant.
4980 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4982 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4983 hscroll is larger than the line width. Fixes long and futile
4984 looping inside extend_face_to_end_of_line (on a TTY) producing
4985 glyphs that are not needed and thrown away.
4987 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4989 * marker.c (set_marker_restricted_both): Simplify by using
4992 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4994 * editfns.c (region_limit): Simplify by using clip_to_bounds.
4996 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
4998 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
4999 not defined (Bug#11768).
5000 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
5001 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
5002 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
5003 followed by gtk_box_set_homogeneous (Bug#11768).
5004 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
5005 (update_theme_scrollbar_width, xg_create_scroll_bar):
5006 Use gtk_scrollbar_new (Bug#11768).
5007 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
5008 (is_box_type): New function (Bug#11768).
5009 (xg_tool_item_stale_p): Call is_box_type.
5010 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
5011 with default display (Bug#11768).
5013 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5015 * xdisp.c (window_hscroll_limited): New function.
5016 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
5017 coordinates when window's hscroll is set to insanely large
5020 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
5022 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
5023 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
5025 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5028 * lisp.h (xzalloc): New prototype. Omit needless casts.
5029 * alloc.c (xzalloc): New function. Omit needless casts.
5030 * charset.c: Omit needless casts. Convert all calls to
5031 xmalloc with following memset to xzalloc.

5081 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5083 * fileio.c (time_error_value): Check the right error number.
5084 Problem reported by Troels Nielsen in
5085 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
5087 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5089 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
5090 This should be fixed in a better way; see Eli Zaretskii in
5091 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
5092 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
5094 * fileio.c (time_error_value): Rename from special_mtime.
5095 The old name's problems were noted by Eli Zaretskii in
5096 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
5098 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
5099 This variable's comment says Emacs needs at least one GDB-visible
5100 symbol of type enum pvec_type, to work around GDB problems.
5101 The symbol's value doesn't matter.
5103 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
5104 that causes compilation to fail on pre-C99 compilers.
5106 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
5108 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
5109 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
5111 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5113 * buffer.c (init_buffer_once): Fix initialization of
5114 headers for buffer_defaults and buffer_local_symbols.
5115 Reported by Juanma Barranquero <lekktu@gmail.com>.
5117 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
5119 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
5120 * lisp.h (enum pvec_type): Use fewer bits.
5121 (PSEUDOVECTOR_SIZE_BITS): New constant.
5122 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
5123 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
5124 change in pvec_type.
5125 (PSEUDOVECTOR_TYPEP): New macro.
5126 (TYPED_PSEUDOVECTORP): Use it.
5127 * fns.c (internal_equal): Adapt code to extract pvectype.
5128 * emacs.c (gdb_pvec_type): Update type.
5129 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
5130 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
5131 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
5132 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
5133 (sweep_vectors): Use it. Use local var `total_bytes' instead of
5134 abusing vector->header.next.nbytes.
5135 (live_vector_p): Use PVEC_TYPE.
5136 (mark_object): Adapt code to extract pvectype. Use switch.
5138 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5140 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
5141 Tighten new eassert a bit.
5143 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5145 Fix compilation with --enable-gcc-warnings and -O1
5147 * doprnt.c (doprnt): Change type of tem to int, initialize
5148 to avoid compiler warning. Add eassert.
5149 * search.c (simple_search): Initialize match_byte to avoid
5150 compiler warning. Add eassert.
5152 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5154 Avoid weird behavior with large horizontal scrolls.
5155 Without this change, for example, large hscroll values would
5156 mess up Emacs's display on Fedora 15 x86, presumably due to
5157 overflows in int calculations in the display code.
5158 Also, if buffers had long lines, Emacs would freeze.
5159 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
5160 (set_window_hscroll): New function, containing the old guts of
5161 Fset_window_hscroll. Return the clipped value.
5162 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
5163 This avoids the need to check against PTRDIFF_MAX.
5165 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
5167 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5169 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
5171 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5173 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
5174 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
5175 since GCC 4.4.6 issues a bogus warning for them.
5177 Fix bugs in file timestamp newness comparisons.
5178 * fileio.c (Ffile_newer_than_file_p):
5179 * lread.c (Fload): Use full timestamp resolution of files,
5180 not just the 1-second resolution, so that files that are only
5181 slightly newer still count as newer.
5182 * fileio.c (Ffile_newer_than_file_p): Don't assume file
5183 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
5185 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
5187 * fileio.c: Improve handling of file time marker. (Bug#11852)
5188 (special_mtime): New function.
5189 (Finsert_file_contents, Fverify_visited_file_modtime):
5190 Use it to set special mtime values consistently.
5192 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
5194 * fileio.c (Finsert_file_contents): Properly handle st_mtime
5195 marker for non-existing file. (Bug#11852)
5197 2012-07-03 Glenn Morris <rgm@gnu.org>
5199 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
5200 and did not make it into globals.h).
5202 2012-07-03 Tom Tromey <tromey@redhat.com>
5204 * window.c (Fset_window_margins, Fset_window_fringes)
5205 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
5206 * textprop.c (Fprevious_property_change): No longer static.
5207 * syntax.c (Fsyntax_table_p): No longer static.
5208 * process.c (Fget_process, Fprocess_datagram_address): No longer

5220 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): No longer
5222 * dired.c (Ffile_attributes): No longer static.
5223 * composite.c (Fcomposition_get_gstring): No longer static.
5224 * callproc.c (Fgetenv_internal): No longer static.
5226 * ccl.h: Remove EXFUNs.
5227 * buffer.h: Remove EXFUNs.
5228 * dispextern.h: Remove EXFUNs.
5229 * intervals.h: Remove EXFUNs.
5230 * fontset.h: Remove EXFUN.
5231 * font.h: Remove EXFUNs.
5232 * dosfns.c (system_process_attributes): Remove EXFUN.
5233 * keymap.h: Remove EXFUNs.
5234 * lisp.h: Remove EXFUNs.
5235 * w32term.h: Remove EXFUNs.
5236 * window.h: Remove EXFUNs.
5237 * xsettings.h: Remove EXFUN.
5238 * xterm.h: Remove EXFUN.
5240 2012-07-03 Glenn Morris <rgm@gnu.org>
5242 * lisp.h (Frandom): Make it visible to C.
5243 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
5244 buffer for invisible buffers. (Bug#1229)
5246 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5248 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
5249 values which aren't power of 2.
5250 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
5251 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
5254 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
5256 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
5258 * alloc.c (mark_object): Revert part of last patch to use `switch'.
5260 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5262 * alloc.c (allocate_vector_block): Remove redundant
5263 calls to mallopt if DOUG_LEA_MALLOC is defined.
5264 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
5265 avoid calls to mallopt if zero_vector is returned.
5267 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5269 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
5270 is enabled, avoid dereferencing NULL current_sblock if
5273 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5275 Cleanup basic buffer management.
5276 * buffer.h (struct buffer): Change layout to use generic vector
5277 marking code. Fix some comments. Change type of 'clip_changed'
5278 to bitfield. Remove unused #ifndef old.
5279 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
5280 (GET_OVERLAYS_AT): Fix indentation.
5281 (for_each_per_buffer_object_at): New macro.
5282 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
5283 (Fbuffer_local_variables): Use it.
5284 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
5285 * alloc.c (allocate_buffer): Adjust to match new layout of
5286 struct buffer. Fix comment.
5287 (mark_overlay): New function.
5288 (mark_buffer): Use it. Use mark_vectorlike to mark normal
5289 Lisp area of struct buffer.
5290 (mark_object): Use it. Adjust marking of misc objects
5291 and related comments.
5293 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
5295 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
5296 wrapper that is not needed because the wrapped code is a no-op (zero
5297 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
5298 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
5300 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
5302 * alloc.c (mark_buffer): Simplify. Remove prototype.
5303 (mark_object): Add comment. Reorganize marking of vector-like
5304 objects. Use CHECK_LIVE for all vector-like objects except buffers
5305 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
5306 Avoid redundant calls to mark_vectorlike for bool vectors.
5308 2012-06-30 Glenn Morris <rgm@gnu.org>
5310 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
5312 * epaths.in (PATH_SITELOADSEARCH): New.
5313 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
5314 This is rather than relying on --enable-locallisppath elements
5315 having "site-lisp" in their names. (Bug#10208#25, 11658)
5317 2012-06-30 Eli Zaretskii <eliz@gnu.org>
5319 * w32proc.c (sys_select): Accept and ignore one more argument.
5321 * w32.c (emacs_gnutls_pull): Call select with one more argument.
5323 * sysselect.h [DOS_NT]: Don't include sys/select.h.
5324 (pselect) [!MS_DOS]: Redirect to sys_select.
5326 * sysdep.c: Don't include dos.h and dosfns.h.
5328 * process.c (sys_select):
5329 * msdos.c (sys_select): Accept one more argument and ignore it.
5331 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
5332 adapt data types and code to that.
5335 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
5336 which clashes with the gnulib function of the same name.
5338 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
5340 * font.c (font_style_to_value, font_style_symbolic)
5341 (font_prop_validate_style): Add type checks for values in
5344 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
5346 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
5349 2012-06-29 Eli Zaretskii <eliz@gnu.org>
5351 * xdisp.c (try_window_id): Undo last change.
5353 * w32.c (getwd): Adjust commentary about startup_dir.
5354 (init_environment): Always call sys_access, even in non-MSVC
5355 builds. Don't chdir to the directory of the Emacs executable.
5356 This undoes code from 1997 which was justified by the need to
5357 "avoid conflicts when removing and renaming directories". But its
5358 downside was that every relative file name was being interpreted
5359 relative to the directory of the Emacs executable, which can never
5360 be TRT. In particular, it broke sys_access when called with
5361 relative file names.
5362 (sys_access): Map GetLastError to errno.
5364 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5366 * window.h (struct window): Change type of 'fringes_outside_margins'
5367 to bitfield. Fix comment. Adjust users accordingly.
5368 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
5370 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
5373 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
5375 * gnutls.c (emacs_gnutls_handshake):
5376 Add QUIT to make the loop interruptible.
5378 2012-06-29 Glenn Morris <rgm@gnu.org>
5380 * charset.c (init_charset): Make lack of etc/charsets fatal.
5382 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5384 * editfns.c (region_limit): Fix type mismatch.
5386 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5388 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
5389 undefined. Convert from xassert to eassert.

5556 Use sprintf return value instead of invoking strlen on result.
5557 In the old days this wasn't portable, since some sprintf
5558 implementations returned char *. But they died out years ago and
5559 Emacs already assumes sprintf returns int.
5560 Similarly for float_to_string.
5561 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

5569 Use sprintf or float_to_string result to avoid need to call strlen.
5570 * data.c (Fnumber_to_string):
5571 Use make_unibyte_string, since the string must be ASCII.
5572 * lisp.h, print.c (float_to_string): Now returns int length.
5573 * term.c (produce_glyphless_glyph):
5574 Use sprintf result rather than recomputing it.
5576 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
5577 * Makefile.in (ALL_CFLAGS):
5578 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

5607 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
5609 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

5612 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
5614 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
5615 instead of truncating it to 63 (admittedly a generous limit).

5675 * keyboard.c (kbd_buffer_get_event):
5676 * process.c (Faccept_process_output):
5677 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
5678 This improves on the previous patch, which introduced a bug
5679 when time_t is unsigned and as wide as intmax_t.
5680 See <http://bugs.gnu.org/9000#51>.
5682 2012-06-23 Eli Zaretskii <eliz@gnu.org>

5745 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5747 Support higher-resolution time stamps (Bug#9000).
5748 The time stamps are only nanosecond-resolution at the C level,
5749 since that's the best that any real-world system supports now.
5750 But they are picosecond-resolution at the Lisp level, as that's
5751 easy, and leaves room for future OS improvements.
5753 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5756 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5757 Don't get current time unless it's needed.
5759 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5760 now provides it if it's absent.
5761 (start_atimer): Port to higher-res time stamps.
5762 Check for time stamp overflow. Don't get current time more
5763 often than is needed.
5765 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5766 Include systime.h, not time.h.
5767 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.

5773 (struct image): Timestamp now has higher resolution.
5775 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5776 has at least microseconds now. All uses removed.
5777 (update_frame, update_single_window, update_window, update_frame_1)
5778 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5779 (duration_to_sec_usec): Remove; no longer needed.
5781 * editfns.c (time_overflow): Now extern.
5782 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
5783 (float-time, Fformat_time_string, Fcurrent_time_string)

5787 (decode_time_components, lisp_seconds_argument): New functions.
5788 (make_time): Now static.
5789 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
5790 Report an error if the time is invalid, rather than having the caller
5793 * fileio.c: Include <stat-time.h>
5794 (Fcopy_file): Copy higher-resolution time stamps.
5795 Prefer to set the time stamp via a file descriptor if that works.
5796 (Fset_file_times, Finsert_file_contents, Fwrite_region)
5797 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
5798 (Fvisited_file_modtime, Fset_visited_file_modtime):
5799 Support higher-resolution time stamps.
5801 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
5803 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
5805 * image.c (prepare_image_for_display, clear_image_cache)
5806 (lookup_image): Port to higer-resolution time stamps.
5808 * keyboard.c (start_polling, bind_polling_period):
5809 Check for time stamp overflow.
5810 (read_char, kbd_buffer_get_event, timer_start_idle)
5811 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
5812 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5813 Port to higher-resolution time stamps. Do not assume time_t is signed.
5814 (decode_timer): New function. Timers are now vectors of length 9,
5815 not 8, to accommodate the picosecond component.
5816 (timer_check_2): Use it.
5818 * nsterm.m (select_timeout, timeval_subtract): Remove.
5819 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5820 as they're a bit more accurate and handle overflow better.
5821 (ns_select): Change prototype to be compatible with pselect.
5822 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5823 * nsterm.h (ns_select): Adjust prototype.
5825 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5826 us-resolution time stamps.
5827 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5829 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5831 * lisp.h (time_overflow): New decl.
5832 (wait_reading_process_output): First arg is now intmax_t, not int,
5833 to accommodate larger waits.
5835 * process.h (struct Lisp_Process.read_output_delay):
5836 Now counts nanoseconds, not microseconds.
5837 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
5839 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
5840 (wait_reading_process_output):
5841 Port to ns-resolution time stamps.
5842 (Faccept_process_output, wait_reading_process_output):
5843 Check for time stamp overflow. Do not assume time_t is signed.
5844 (select_wrapper): Remove; we now use pselect.
5845 (Fprocess_attributes): Now generates ns-resolution time stamps.
5847 * sysdep.c: Include utimens.h. Don't include utime.h
5848 or worry about struct utimbuf; gnulib does that for us now.
5849 (gettimeofday): Remove; gnulib provides a substitute.
5850 (make_timeval): New function.
5851 (set_file_times): Now sets ns-resolution time stamps.
5852 New arg FD; all uses changed.
5853 (time_from_jiffies, ltime_from_jiffies, get_up_time)
5854 (system_process_attributes):
5855 Now returns ns-resolution time stamp. All uses changed.
5856 Check for time stamp overflow.
5858 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5859 provides a substitute now.
5861 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5862 since it guarantees struct timespec.
5863 (EMACS_TIME): Now struct timespec, so that we can support
5864 ns-resolution time stamps.
5865 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5866 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5867 (EMACS_USECS): Remove.
5868 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5869 so multiply the arg by 1000 before storing it.
5870 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
5872 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
5873 Port to ns-resolution time stamps.
5874 (EMACS_TIME_NEG_P): Remove; replaced by....
5875 (EMACS_TIME_SIGN): New macro.
5876 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)

5879 (make_timeval, make_lisp_time, decode_time_components): New decls.
5880 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in

5922 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5923 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,

5975 gets killed during executing of this function (Bug#11665).

6346 would mishandle a string argument "Xc" if X was a multibyte
6347 character of length 2: it would truncate after X's first byte
6348 rather than including all of X.
6350 2012-06-06 Chong Yidong <cyd@gnu.org>
6352 * buffer.c (word_wrap): Doc fix.
6354 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>
6356 * xdisp.c (note_mode_line_or_margin_highlight): Pacify gcc -Wall.

6366 binary via PaX flags if the paxctl utility is available.
6367 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6368 Restore PaX flags to their default. (Bug#11398)

6372 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
6375 2012-06-03 Chong Yidong <cyd@gnu.org>
6377 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
6378 (note_mode_line_or_margin_highlight): If there is no help echo,
6379 use mode-line-default-help-echo. Handle the case where the mouse
6380 position is past the end of the mode line string.
6382 * buffer.c (buffer_local_value_1): New function, split from
6383 Fbuffer_local_value; can return Qunbound.
6384 (Fbuffer_local_value): Use it.

6387 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
6389 * sysdep.c (system_process_attributes): Improve comment.
6391 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
6393 * keyboard.c: Export real-this-command to Elisp.
6394 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
6395 and DEFVAR it. Update all users.
6397 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
6399 * minibuf.c (Fassoc_string): Remove duplicate declaration.
6401 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
6402 Convert pctcpu and pctmem to Lisp float properly.
6403 Let the compiler fold better, as 100.0/0x8000 is exact.
6405 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
6407 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
6410 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
6412 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
6414 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
6416 For a 'struct window', replace some Lisp_Object fields to
6417 bitfields where appropriate, remove unused fields.
6418 * window.h (struct window): Remove unused 'last_mark_x' and
6419 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
6420 change it's type from Lisp_Object to bitfield.
6421 Change type of 'force_start', 'optional_new_start',
6422 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
6423 fields from Lisp_Object to bitfield. Adjust users accordingly.
6425 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6427 Pacify gcc -Wdouble-precision when using Xaw.
6428 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
6429 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
6430 Use 'float' consistently, rather than 'float' in most places
6431 and 'double' in a couple of places.
6433 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6435 * xdisp.c (handle_stop): Detect whether we have overlay strings
6436 loaded by testing it->current.overlay_string_index to be
6437 non-negative, instead of checking whether n_overlay_strings is
6438 positive. (Bug#11587)
6440 2012-05-31 Chong Yidong <cyd@gnu.org>
6442 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
6444 * doc.c (Fsubstitute_command_keys): Doc fix.
6446 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6448 * search.c (search_buffer): Remove calls to
6449 r_alloc_inhibit_buffer_relocation, as it is now called by
6450 maybe_unify_char, which was the cause of relocation of buffer text
6453 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6455 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6456 for the duration of call to load_charset, to avoid problems with
6457 callers of maybe_unify_char that access buffer text through C
6460 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6461 decrement the inhibition flag, instead of just setting or
6464 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6466 Remove obsolete '#define static' cruft.
6467 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6468 This #undef was "temporary" in 2000; it is no longer needed
6469 now that '#define static' has gone away.
6470 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6471 (gray_bitmap_bits): Remove; no longer needed.
6472 All uses replaced with definiens.
6473 * xterm.c: Include "bitmaps/gray.xbm".
6475 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6477 Clean up __executable_start, monstartup when --enable-profiling.
6478 The following changes affect the code only when profiling.
6479 * dispnew.c (__executable_start): Rename from safe_bcopy.
6480 Define only on platforms that need it.
6481 * emacs.c: Include <sys/gmon.h> when profiling.
6482 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6483 (__executable_start): Remove decl, since lisp.h does it now.
6484 (safe_bcopy): Remove decl; no longer has that name.
6485 (main): Coalesce #if into single bit of code, for simplicity.
6486 Cast pointers to uintptr_t, since standard libraries want integers
6488 * lisp.h (__executable_start): New decl.
6490 2012-05-31 Glenn Morris <rgm@gnu.org>
6492 * image.c (Fimagemagick_types): Doc fix.
6494 2012-05-30 Jim Meyering <meyering@redhat.com>
6496 * callproc.c (Fcall_process_region): Include directory component
6497 in mkstemp error message (Bug#11586).
6499 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6501 * alloc.c, lisp.h (make_pure_vector): Now static.
6503 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

6509 (Qdefun): Move from eval.c.
6510 * lisp.h (Qdefun): Remove.
6511 * lread.c (read1): Tiny simplification.
6513 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
6515 Do not create empty overlays with the evaporate property (Bug#9642).
6516 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6517 Bug#9642, but explicitly check that the buffer the overlay would
6518 be moved to is live and rearrange lines to make sure that errors
6519 will not put the overlay in an inconsistent state.
6520 (Fdelete_overlay): Cosmetics.
6522 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6524 * w32term.c (my_bring_window_to_top): New function.
6525 (x_raise_frame): Use handle returned by DeferWindowPos, which
6526 could be different from the original one.
6527 Call my_bring_window_to_top instead of my_set_foreground_window.
6530 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6531 by calling BringWindowToTop.
6533 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6534 (WM_EMACS_END): Increase by one.
6536 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6538 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6539 This avoids undefined behavior that might cause the eassert
6540 to not catch an out-of-range value.
6542 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6544 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
6545 Update dependencies.
6547 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6549 * bidi.c (bidi_mirror_char): Fix last change.
6551 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
6553 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
6554 when referring to sectname field in printf format.
6556 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
6558 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6559 Only r_alloc_inhibit_buffer_relocation needed to be added;
6560 the others were already declared.
6562 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6563 before checking whether it's out of range. Put the check inside
6565 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6567 2012-05-27 Ken Brown <kbrown@cornell.edu>
6569 * callproc.c (Fcall_process): Restore a line that was accidentally
6570 commented out in the 2011-02-13 change (bug#11547).
6572 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6574 * lisp.h [REL_ALLOC]: Add prototypes for external functions
6575 defined on ralloc.c.
6577 * buffer.c [REL_ALLOC]: Remove prototypes of
6578 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
6579 they are now on lisp.h.
6581 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6583 * search.c (search_buffer): Use it to inhibit relocation of buffer
6584 text while re_search_2 is doing its job, because re_search_2 is
6585 passed C pointers to buffer text. (Bug#11519)
6587 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6590 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6591 state after an additional call to move_it_in_display_line_to, keep
6592 the values of it->max_ascent and it->max_descent found for the
6594 (pos_visible_p): Revert the comparison against bottom_y to what it
6595 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
6598 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6600 Fix coding-related core dumps with gcc -ftrapv.
6601 The code was computing A - B, where A and B are pointers, and B is
6602 random garbage. This can lead to core dumps on platforms that
6603 have special pointer registers, and it also leads to core dumps on
6604 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6605 A - B only when B is initialized properly.
6606 * coding.c (coding_set_source, coding_set_destination): Return void.
6607 (coding_change_source, coding_change_destinations): New functions,
6608 with the old behaviors of coding_set_source and coding_set_destination.
6609 All callers that need an offset changed to use these new functions.
6611 2012-05-26 Glenn Morris <rgm@gnu.org>
6613 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
6615 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6617 Extend mouse support on W32 text-mode console.
6618 * xdisp.c (draw_row_with_mouse_face):
6619 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6621 * w32console.c: Include window.h.
6622 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6624 (initialize_w32_display): Initialize mouse-highlight data.
6626 * w32inevt.c: Include termchar.h and window.h.
6627 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6628 moves, call note_mouse_highlight. If help_echo changed, call
6629 gen_help_event to produce help-echo message in the echo area.
6630 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6633 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6635 * lread.c (read1): Simplify slightly to avoid an overflow warning
6636 with GCC 4.7.0 on x86-64.
6638 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6640 * bidi.c (bidi_mirror_char): Revert last change: an int is
6641 definitely wide enough here.
6643 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
6645 Fix integer width and related bugs (Bug#9874).
6646 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
6647 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
6648 (string_bytes, check_sblock, allocate_string_data):
6649 (compact_small_strings, Fmake_bool_vector, make_string)
6650 (make_unibyte_string, make_multibyte_string)
6651 (make_string_from_bytes, make_specified_string)
6652 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
6653 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
6655 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6656 (allocate_pseudovector):
6657 Use int, not EMACS_INT, where int is wide enough.
6658 (inhibit_garbage_collection, Fgarbage_collect):
6659 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6660 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
6661 int might not be wide enough.
6662 (bidi_cache_search, bidi_cache_find, bidi_init_it)
6663 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6664 (bidi_at_paragraph_end, bidi_find_paragraph_start)
6665 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
6666 (bidi_level_of_next_char, bidi_move_to_visually_next):
6667 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6668 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
6669 (Fkill_buffer, Fset_buffer_major_mode)
6670 (advance_to_char_boundary, Fbuffer_swap_text)
6671 (Fset_buffer_multibyte, overlays_at, overlays_in)
6672 (overlay_touches_p, struct sortvec, record_overlay_string)
6673 (overlay_strings, recenter_overlay_lists)
6674 (adjust_overlays_for_insert, adjust_overlays_for_delete)
6675 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
6676 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
6677 (Foverlay_recenter, last_overlay_modification_hooks_used)
6678 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6679 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6680 (validate_region): Omit unnecessary test for b <= e,
6681 since that's guaranteed by the previous test.
6682 (adjust_overlays_for_delete): Avoid pos + length overflow.
6683 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6684 (report_overlay_modification):
6685 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6686 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
6687 Omit pointer cast, which isn't needed anyway, and doesn't work
6688 after the EMACS_INT -> ptrdiff_t change.
6689 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
6690 * buffer.h: Adjust decls to match defn changes elsewhere.
6691 (struct buffer_text, struct buffer):
6692 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6693 Use EMACS_INT, not int, where int might not be wide enough.
6694 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
6695 not int, to avoid needless 32-bit limit on 64-bit hosts.
6696 (exec_byte_code): Use tighter memory-full test, one that checks
6697 for alloca overflow. Don't compute the address of the object just
6698 before an array, as that's not portable. Use EMACS_INT, not
6699 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
6700 * callint.c (Fcall_interactively):
6701 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6702 * callproc.c (call_process_kill, Fcall_process):
6703 Don't assume pid_t fits into an Emacs fixnum.
6704 (call_process_cleanup, Fcall_process, child_setup):
6705 Don't assume pid_t fits into int.
6706 (call_process_cleanup, Fcall_process, delete_temp_file)
6707 (Fcall_process_region):
6708 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6709 (Fcall_process): Simplify handling of volatile integers.
6710 Use int, not EMACS_INT, where int will do.
6711 * casefiddle.c (casify_object, casify_region, operate_on_word)
6712 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
6713 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6714 (casify_object): Avoid integer overflow when overallocating buffer.
6715 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
6716 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
6717 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
6718 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6719 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6720 integers are now checked earlier. All uses replaced with XINT.
6722 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6723 For CCL_MapSingle, check that content and value are in int range.
6724 (ccl_driver, Fregister_code_conversion_map):
6725 Check that Vcode_version_map_vector is a vector.
6726 (resolve_symbol_ccl_program): Check that vector header is in range.
6727 Always copy the vector, so that we can check its contents reliably
6728 now rather than having to recheck each instruction as it's being
6729 executed. Check that vector words fit in 'int'.
6730 (ccl_get_compiled_code, Fregister_ccl_program)
6731 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6732 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
6733 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
6734 contents are in range.
6735 (Fccl_execute_on_string): Check that status is in range.
6736 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
6737 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
6738 Accept and return EMACS_INT, not int, because callers can pass values
6740 (c_string_width, strwidth, lisp_string_width, chars_in_text)
6741 (multibyte_chars_in_text, parse_str_as_multibyte)
6742 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
6743 (str_as_unibyte, str_to_unibyte, string_count_byte8)
6744 (string_escape_byte8, Fget_byte):
6745 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6746 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
6747 avoid mishandling large integers.
6748 * character.h: Adjust decls to match defn changes elsewhere.
6749 * charset.c (load_charset_map_from_file, find_charsets_in_text)
6750 (Ffind_charset_region):
6751 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6752 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
6753 (load_charset_map_from_vector, Fdefine_charset_internal):
6754 Don't assume fixnum fits in int.
6755 (load_charset_map_from_vector, Fmap_charset_chars):
6756 Remove now-unnecessary CHECK_NATNUMs.
6757 (Fdefine_charset_internal): Check ranges here, more carefully.
6758 Don't rely on undefined behavior with signed left shift overflow.
6759 Don't assume unsigned int fits into fixnum, or that fixnum fits
6760 into unsigned int. Don't require max_code to be a valid fixnum;
6761 that's not true for gb10830 4-byte on a 32-bit host. Allow
6762 invalid_code to be a cons, for the same reason. Require code_offset
6763 to be a character. Avoid int overflow if max_char is close
6765 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
6766 this is intended anyway and avoids some undefined behavior.
6767 (load_charset_map): Pass unsigned, not int, as 2nd arg of
6768 INDEX_TO_CODE_POINT, as that's what it expects.
6769 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
6770 * charset.h (DECODE_CHAR): Return int, not unsigned;
6771 this is what was intended anyway, and it avoids undefined behavior.
6772 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
6773 integer-overflow issues.
6774 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
6775 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
6776 where the argument is EMACS_INT, and this behavior is not intended.
6777 * chartab.c (Fmake_char_table, Fset_char_table_range)
6778 (uniprop_get_decoder, uniprop_get_encoder):
6779 Don't assume fixnum fits in int.
6780 * cmds.c (move_point): New function, that does the gist of
6781 Fforward_char and Fbackward_char, but does so while checking
6782 for integer overflow more accurately.

7493 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
7494 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
7495 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
7496 * s/ms-w32.h (DATA_START):
7497 Move here from removed file m/intel386.h.
7498 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
7499 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
7501 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
7503 Assume C89 or later.
7504 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
7505 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
7507 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
7508 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
7509 * textprop.c, tparam.c (NULL): Remove.
7510 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
7511 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
7512 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
7513 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
7514 * xterm.c (input_signal_count): Assume volatile works.
7516 2012-05-21 Ken Brown <kbrown@cornell.edu>
7518 * xgselect.c (xg_select): Fix first argument in call to 'select'
7521 2012-05-20 Ken Brown <kbrown@cornell.edu>
7523 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
7524 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
7526 2012-05-19 Ken Brown <kbrown@cornell.edu>
7528 * xfns.c (x_in_use): Remove `static' qualifier.
7529 * xterm.h (x_in_use): Declare.
7530 * xgselect.c: Include xterm.h.
7531 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
7532 and `display_arg' (bug#9754).
7534 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
7536 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
7538 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
7539 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
7541 2012-05-18 Eli Zaretskii <eliz@gnu.org>
7543 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
7545 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
7546 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
7548 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
7549 reference to image_cache->refcount.
7550 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
7552 2012-05-17 Juri Linkov <juri@jurta.org>
7554 * search.c (Fword_search_regexp, Fword_search_backward)
7555 (Fword_search_forward, Fword_search_backward_lax)
7556 (Fword_search_forward_lax): Move functions to isearch.el
7557 (bug#10145, bug#11381).
7559 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
7561 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
7563 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
7565 * lread.c (init_obarray): Declare Qt and Qnil as special.
7567 2012-05-14 Glenn Morris <rgm@gnu.org>
7569 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
7570 Put "libexec" before "bin", for the sake of init_callproc_1.
7572 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7574 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
7576 * unexaix.c: Port to more-recent AIX compilers.
7577 (report_error, report_error_1, make_hdr, copy_sym)
7578 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
7579 Make arguments const char *, not char *, to avoid violations of C
7580 standard and to fix some AIX warnings reported by Gilles Pion.
7582 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7584 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
7585 already have overlays loaded.
7586 (handle_single_display_spec): Before returning without displaying
7587 fringe bitmap, synchronize the bidi iterator with the main display
7588 iterator, by calling iterate_out_of_display_property.
7589 (iterate_out_of_display_property): Detect buffer iteration by
7590 testing that it->string is a Lisp string.
7591 (get_next_display_element): When the current object is exhausted,
7592 and there's something on it->stack, call set_iterator_to_next to
7593 proceed with what's on the stack, instead of returning zero.
7594 (set_iterator_to_next): If called at the end of a Lisp string,
7595 proceed to consider_string_end without incrementing string
7596 position. Don't increment display vector index past the end of
7597 the display vector. (Bug#11417)
7598 (pos_visible_p): Don't report a position visible when move_it_to
7599 stopped at the last line of window, which happens to be scanned
7600 backwards by the bidi iteration. (Bug#11464)
7602 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7604 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7605 and right-margin display specs even if the spec is invalid or we
7606 are on a TTY, and thus unable to display on the fringes.
7607 That's because the text with the property will not be displayed anyway,
7608 so we need to signal to the caller that this is a "replacing"
7609 display spec. This fixes display when the spec is invalid or we
7612 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7614 * unexaix.c (make_hdr): Fix typo in prototype.
7615 This bug broke the build on AIX. Problem reported by Gilles Pion.
7617 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
7619 * keyboard.c (kbd_buffer_get_event): Read special events also in
7620 batch mode. (Bug#11415)
7622 2012-05-12 Glenn Morris <rgm@gnu.org>
7624 * ns.mk: Update for ns_appbindir no longer having trailing "/".
7626 2012-05-12 Eli Zaretskii <eliz@gnu.org>
7628 * lisp.mk (lisp): Add newcomment.elc.
7630 2012-05-12 Glenn Morris <rgm@gnu.org>
7632 * Makefile.in (MKDIR_P): New, set by configure.
7633 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
7635 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
7637 Remove unused function hourglass_started.
7638 * dispextern.h (hourglass_started):
7639 * w32fns.c (hourglass_started):
7640 * xdisp.c (hourglass_started): Remove.
7642 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7644 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7645 Update dependencies.
7647 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7649 * xgselect.c (xg_select): Put maxfds+1 into a var.
7650 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
7652 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7654 2012-05-10 Dave Abrahams <dave@boostpro.com>
7656 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7657 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7659 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7661 * dbusbind.c (xd_registered_buses): New internal Lisp object.
7662 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7663 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7664 Initialize xd_registered_buses.
7666 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7668 Untag more efficiently if USE_LSB_TAG.
7669 This is based on a proposal by YAMAMOTO Mitsuharu in
7670 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7671 For an admittedly artificial (nth 8000 longlist) benchmark on
7672 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7673 Emacs's overall text size by 1%.
7674 * lisp.h (XUNTAG): New macro.
7675 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7676 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7677 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7678 * eval.c (Fautoload):
7679 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7680 * frame.h (XFRAME): Use XUNTAG.
7682 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7683 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7684 Remove unportable assumptions about print widths of types like
7686 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7687 intptr_t when converting between pointer and integer, to avoid GCC
7688 warnings about wrong width.
7690 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7692 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7693 stack for each reader_thread, instead of defaulting to 8MB
7694 determined by the linker. This avoids failures in creating
7695 subprocesses on Windows 7, see the discussion in this thread:
7696 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7698 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7700 Fix up display of the *Minibuf-0* buffer in the mini window.
7701 * keyboard.c (read_char): Don't clear the echo area if there's no
7703 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7704 contents of *Minibuf-0*) if there's no message displayed in its stead.
7706 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7708 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7711 2012-05-06 Chong Yidong <cyd@gnu.org>
7713 * lisp.mk (lisp): Update.
7715 2012-05-05 Jim Meyering <meyering@redhat.com>
7717 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7719 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7721 * data.c (PUT_ERROR): New macro.
7722 (syms_of_data): Use it. Add new error type `user-error'.
7723 * undo.c (user_error): New function.
7724 (Fprimitive_undo): Use it.
7725 * print.c (print_error_message): Adjust print style for `user-error'.
7726 * keyboard.c (user_error): New function.
7727 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7729 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7731 Do not limit current-time-string to years 1000..9999.
7732 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7733 (Fcurrent_time_string): Support any year that is supported by the
7734 underlying localtime representation. Don't use asctime, as it
7735 has undefined behavior for years outside the range -999..9999.
7737 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7739 Fix race conditions involving setenv, gmtime, localtime, asctime.
7740 Without this fix, interrupts could mess up code that uses these
7741 nonreentrant functions, since setting TZ invalidates existing
7742 tm_zone or tzname values, and since most of these functions return
7743 pointers to static storage.
7744 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7745 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7746 Grow the critical sections to include not just invoking
7747 localtime/gmtime, but also accessing these functions' results
7748 including their tm_zone values if any, and any related TZ setting.
7749 (format_time_string): Last arg is now struct tm *, not struct tm **,
7750 so that the struct tm is saved in the critical section.
7751 All callers changed. Simplify allocation of initial buffer, partly
7752 motivated by the fact that memory allocation needs to be outside
7753 the critical section.
7755 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7757 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7758 with RESET_INTERVAL.
7760 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7761 Remove duplicated buffer name initialization.
7763 2012-05-02 Jim Meyering <jim@meyering.net>
7765 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7767 * xfns.c (x_window): Use xstrdup (Bug#11375).
7769 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7771 * xdisp.c (pos_visible_p): If already at a newline from the
7772 display string before the 'while' loop, don't walk back the glyphs
7773 from it3.glyph_row. Solves assertion violation when the display
7774 string begins with a newline (egg.el). (Bug#11367)
7776 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7778 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7781 2012-05-01 Glenn Morris <rgm@gnu.org>
7783 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7784 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7785 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7786 All were removed before 23.1.
7788 * dispnew.c: Remove HAVE_LIBNCURSES test;
7789 it is always true on relevant platforms.
7791 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7792 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7794 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
7796 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
7798 * .gdbinit (xpr): Remove checks for no longer existing misc types.
7799 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
7802 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
7804 Do not avoid creating empty evaporating overlays (Bug#9642).
7805 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7806 That is, do not delete an evaporating overlay if it becomes
7807 empty after its bounds are adjusted to fit within its buffer.
7808 This fix caused other problems, and I'm reverting it until we get
7809 to the bottom of them.
7811 2012-04-27 Chong Yidong <cyd@gnu.org>
7813 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7815 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7817 * xdisp.c (pos_visible_p): If the window start position is beyond
7818 ZV, start the display from buffer beginning. Prevents assertion
7819 violation in init_iterator when the minibuffer window is scrolled
7822 * window.c (window_scroll_pixel_based): Likewise.
7824 2012-04-27 Chong Yidong <cyd@gnu.org>
7826 * keymap.c (where_is_internal): Doc fix (Bug#10872).
7828 2012-04-27 Glenn Morris <rgm@gnu.org>
7830 * fileio.c (Fcopy_file, Fset_file_selinux_context):
7831 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
7833 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7835 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
7836 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
7838 2012-04-26 Eli Zaretskii <eliz@gnu.org>
7840 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7841 display element, check also the underlying string or buffer
7842 character. (Bug#11341)
7844 * w32menu.c: Include w32heap.h.
7845 (add_menu_item): If the call to AppendMenuW (via
7846 unicode_append_menu) fails, disable Unicode menus only if we are
7847 running on Windows 9X/Me.
7849 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7851 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
7852 (xgetint): Add missing shift for LSB tags.
7854 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7856 * keyboard.c (read_char): Don't wipe echo area for select window
7857 events: These might get delayed via `mouse-autoselect-window'
7860 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
7862 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
7863 manipulation of :loaded-from data.
7865 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
7867 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
7868 now a cons (bug#11311).
7870 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7872 Do not create empty overlays with the evaporate property (Bug#9642).
7873 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7874 if it becomes empty after its bounds are adjusted to fit within
7875 its buffer. Without this fix, in a nonempty buffer (let ((o
7876 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7877 yields an empty overlay that has the evaporate property, which is
7878 not supposed to happen.
7880 Fix minor GTK3 problems found by static checking.
7881 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7882 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7883 (struct _EmacsFixedClass, emacs_fixed_get_type):
7884 Move decls here from emacsgtkfixed.h, since they needn't be public.
7885 (emacs_fixed_get_type): Now static.
7886 (emacs_fixed_class_init): Omit unused local.
7887 (emacs_fixed_child_type): Remove; unused.

7889 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7890 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
7891 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
7892 (EMACS_FIXED_GET_CLASS): Remove; unused.
7893 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
7895 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
7896 Problem reported by Juanma Barranquero for Windows -Wunused-function.
7898 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7900 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
7901 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
7902 (__malloc_size_t, __malloc_ptrdiff_t):
7903 Remove. All uses removed, replaced by the definiens if needed,
7904 since we can assume C89 or better now.
7905 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
7906 (protect_malloc_state, align, get_contiguous_space)
7907 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
7908 (malloc_atfork_handler_child, malloc_enable_thread)

7913 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
7914 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
7915 Define using prototypes, not old style.
7916 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
7917 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
7918 (align): Don't assume that signed integer overflow wraps around.
7919 Omit unused local var.
7920 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
7921 (_free_internal_nolock, memalign, mallochook, reallochook):
7922 Omit no-longer-needed casts.
7923 (valloc): Use getpagesize, not __getpagesize.
7924 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
7925 (struct hdr): The 'magic' member is now size_t, not unsigned long.
7927 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
7929 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
7931 Move functions from C to Lisp. Make non-blocking method calls
7932 the default. Implement further D-Bus standard interfaces.
7934 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
7935 (QCdbus_request_name_allow_replacement)
7936 (QCdbus_request_name_replace_existing)
7937 (QCdbus_request_name_do_not_queue)

7941 (QCdbus_request_name_reply_already_owner): Move to dbus.el.
7942 (QCdbus_registered_serial, QCdbus_registered_method)
7943 (QCdbus_registered_signal): New Lisp objects.
7944 (XD_DEBUG_MESSAGE): Use sizeof.

7980 * alloc.c: Handle unusual debugging option combinations.
7981 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
7982 since the two debugging options are incompatible.
7983 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7985 (mem_init, mem_insert, mem_insert_fixup):
7986 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

8016 * print.c (print_preprocess): Only check print_depth if print-circle
8018 (print_object): Check for cycles even when print-circle is nil and
8019 print-gensym is t, but only check print_depth if print-circle is nil.
8021 2012-04-20 Chong Yidong <cyd@gnu.org>
8023 * process.c (wait_reading_process_output): If EIO occurs on a pty,

8079 New extern decls, to avoid calling undeclared functions.
8080 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
8081 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
8082 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

8123 Remove definition of GC_MARK_STACK, since the default now works.
8124 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
8125 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
8126 no longer the default.
8127 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
8129 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

8152 2012-04-11 Daniel Colascione <dancol@dancol.org>
8154 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
8155 against is gone. It's better to use vfork now so that when Cygwin
8156 gains a new, working vfork, we use it automatically (bug#10398).
8158 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

8179 being loaded (bug#10424).
8181 2012-04-09 Glenn Morris <rgm@gnu.org>
8183 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
8184 not just in the obarray, before snarfing them. (Bug#11036)

8211 * minibuf.c (Fread_variable): Callers changed.
8213 2012-04-09 Eli Zaretskii <eliz@gnu.org>
8215 * xdisp.c (set_cursor_from_row): If the display string appears in
8216 the buffer at position that is closer to point than the position
8217 after the display string, display the cursor on the first glyph of
8218 the display string. Fixes cursor display when a 'display' text
8219 property immediately follows invisible text. (Bug#11094)
8221 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
8223 composite.c: use 'double' consistently
8224 * composite.c (get_composition_id): Use 'double' consistently
8225 instead of converting 'float' to 'double' and vice versa; this is
8226 easier to understand and avoids a GCC warning.
8228 2012-04-09 Glenn Morris <rgm@gnu.org>
8230 * Makefile.in: Generate leim-list with bootstrap-emacs, in
8231 preparation for dumping it with emacs. (Bug#4789)

8253 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
8254 (mark_memory): Mark Lisp_Objects only if pointers might hide in

8273 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
8274 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
8275 [!WINDOWSNT]: New macros.
8276 (init_libxml2_functions, libxml2_loaded_p): New functions.
8277 (parse_region): Call fn_xmlCheckVersion instead of using the macro
8278 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
8279 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
8280 Calls xmlCleanupParser only if libxml2 was loaded (or statically
8282 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
8283 Call init_libxml2_functions before calling libxml2 functions.
8284 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
8286 * emacs.c: Don't include libxml/parser.h.

8300 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
8301 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
8302 about subtle differences between FETCH_CHAR* and STRING_CHAR*
8303 macros related to unification of CJK characters. For the details,
8304 see the discussion following the message here:
8305 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
8307 2012-04-04 Chong Yidong <cyd@gnu.org>
8309 * keyboard.c (Vdelayed_warnings_list): Doc fix.

8321 2012-03-31 Eli Zaretskii <eliz@gnu.org>
8323 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
8324 position we get to after a call to move_it_to fails the
8325 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
8326 only if we wind up in a string from display property. (Bug#11063)
8328 * window.c (Fdelete_other_windows_internal): Invalidate the row
8329 and column information about mouse highlight, so that redisplay
8330 restores it after reallocating the glyph matrices. (Bug#7464)
8332 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
8333 string comes from a `display' text property, use the buffer
8334 position of that property as if we actually saw that position in
8336 (move_it_by_lines): Remove the assertion that
8337 "it->current_x == 0 && it->hpos == 0" which can be legitimately
8338 violated when there's a before-string at the beginning of a line.
8341 2012-03-30 Eli Zaretskii <eliz@gnu.org>
8343 * xdisp.c (append_space_for_newline): If the default face was
8344 remapped, use the remapped face for the appended newline.
8345 (extend_face_to_end_of_line): Use the remapped default face for
8346 extending the face to the end of the line.
8347 (display_line): Call extend_face_to_end_of_line when the default
8348 face was remapped. (Bug#11068)
8350 2012-03-29 Eli Zaretskii <eliz@gnu.org>

8372 handle-select-window too (Bug#8996).
8374 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
8376 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.

8380 * dispextern.h (struct glyph): Change the bit length of
8381 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
8383 2012-03-24 Eli Zaretskii <eliz@gnu.org>
8385 * s/ms-w32.h (tzname): Include time.h before redirecting to

8396 2012-03-23 Eli Zaretskii <eliz@gnu.org>
8398 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
8399 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
8400 when fetching a multibyte character consumes more bytes than
8401 CHAR_BYTES returns, due to unification of CJK characters in
8402 string_char. (Bug#11073)
8404 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
8406 * process.c (wait_reading_process_output): Handle pty disconnect
8407 by refraining from sending oneself a SIGCHLD (bug#10933).

8430 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
8431 to reflect default non-nil value of redisplay-dont-pause.
8433 2012-03-19 Kenichi Handa <handa@m17n.org>
8435 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
8436 it fit in a valid range (Bug#11003).
8438 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8440 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8441 that is not from display property, accept the row as a "cursor
8442 row" if one of the string's character has a non-nil `cursor'
8443 property. Fixes cursor positioning when there are newlines in
8444 overlay strings, e.g. in icomplete.el. (Bug#11035)
8446 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

8477 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8480 2012-03-03 Glenn Morris <rgm@gnu.org>
8482 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

8493 2012-03-02 Glenn Morris <rgm@gnu.org>
8495 * buffer.c (buffer-list-update-hook): Doc fix.
8497 2012-02-29 Eli Zaretskii <eliz@gnu.org>

8500 push_it before setting up the iterator for the first overlay
8501 string, even if we have an empty string loaded.
8502 (next_overlay_string): If there's an empty string on the iterator
8503 stack, pop the stack. (Bug#10903)
8505 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8507 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8508 Suggested by Stefan Monnier in
8509 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8510 * alloc.c (widen_to_Lisp_Object): New static function.
8511 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8512 and widening them to Lisp_Objects. This would work even if
8513 USE_LSB_TAG is defined and wide integers are used, which might
8514 happen in a future version of Emacs.
8516 2012-02-25 Chong Yidong <cyd@gnu.org>
8518 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

8522 (x_clipboard_manager_save_all): Print an informative message
8523 before saving to clipboard manager.
8525 2012-02-24 Chong Yidong <cyd@gnu.org>
8527 * keyboard.c (process_special_events): Handle all X selection

8532 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
8533 call when setting menu-bar-lines and tool-bar-lines parameters.
8534 (unwind_create_frame_1): New helper function.
8536 * window.c (inhibit_window_configuration_change_hook): New var.
8537 (run_window_configuration_change_hook): Obey it.
8538 (syms_of_window): Initialize it.
8540 2012-02-22 Chong Yidong <cyd@gnu.org>
8542 * xterm.c (x_draw_image_relief): Add missing type check for

8555 when computing $valmask.
8557 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8558 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8559 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8560 It's useless in that case, and it can cause problems on hosts
8561 that allocate halves of EMACS_INT values separately.
8562 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8563 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8564 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8565 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8566 it avoids undefined behavior on hosts where shifting right by more
8567 than the word width has undefined behavior.
8569 2012-02-19 Chong Yidong <cyd@gnu.org>
8571 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
8572 (Funhandled_file_name_directory, Ffile_name_as_directory)

8591 2012-02-15 Chong Yidong <cyd@gnu.org>
8593 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
8594 marked as special. Also, starting docstrings with * is obsolete.
8596 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>

8612 as that creates a dangerous corner case.
8614 * window.c (Fdelete_window_internal): Invalidate the mouse
8615 highlight (Bug#9904).
8617 2012-02-12 Glenn Morris <rgm@gnu.org>

8622 * nsselect.m (Fx_own_selection_internal)
8623 (Fx_disown_selection_internal, Fx_selection_exists_p)
8624 (Fx_selection_owner_p, Fx_get_selection_internal):
8625 Sync docs and argument specs with the xselect.c versions.

8647 2012-02-07 Chong Yidong <cyd@gnu.org>
8649 * buffer.c (Fbuffer_local_variables)
8650 (buffer_lisp_local_variables): Handle unbound vars correctly;
8651 don't let Qunbound leak into Lisp.
8653 2012-02-07 Glenn Morris <rgm@gnu.org>
8655 * image.c (Fimagemagick_types): Doc fix.
8657 * image.c (imagemagick-render-type): Change it from a lisp object

8663 * doc.c (store_function_docstring): Avoid applying docstring of
8664 alias to base function (Bug#2603).

8690 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
8692 Handle overflow when computing char display width (Bug#9496).
8693 * character.c (char_width): Return EMACS_INT, not int.
8694 (char_width, c_string_width): Check for overflow when
8695 computing the width; this is possible now that individual
8696 characters can have unbounded width. Problem introduced
8697 by merge from Emacs 23 on 2012-01-19.
8699 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

8728 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
8729 first 2 arguments are identical. This makes inserting large
8730 output from a subprocess an order of magnitude faster on
8731 MS-Windows, where all sbrk'ed memory is always contiguous.

8837 emacs: fix an auto-save permissions race condition (Bug#10400)
8838 * fileio.c (auto_saving_dir_umask): New static var.
8839 (Fmake_directory_internal): Use it.
8840 (do_auto_save_make_dir): Set it, instead of invoking chmod after
8841 creating the directory. The old code temporarily assigns
8842 too-generous permissions to the directory.
8843 (do_auto_save_eh): Clear it.
8844 (Fdo_auto_save): Catch all errors, not just file errors, so
8845 that the var is always cleared.

8849 * search.c (scan_buffer): Pass character positions to
8850 know_region_cache, not byte positions. (Bug#6540)

8902 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
8903 property that ends at ZV, so that the bidi iteration could be

9350 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
9351 is set, removing the need for VIRT_ADDRESS_VARIES.
9352 (PURE_P): Use a more-efficient implementation that needs just one

9367 (erase_phys_cursor, update_window_cursor, show_mouse_face)
9368 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
9369 behave as if the cursor position were at the window margin.
9371 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
9372 and the cursor position is out of bounds, behave as if the cursor
9373 position were at the window margin. (Bug#10075)
9375 2011-11-18 Chong Yidong <cyd@gnu.org>
9377 * window.c (Fwindow_combination_limit): Make first argument

9403 * dispnew.c (verify_row_hash): Call row_hash for computing the
9404 hash code of a row, instead of duplicating code from xdisp.c.
9406 * dispextern.h (row_hash): Add prototype.

9880 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
9882 * w32fns.c (w32_default_color_map): New function,
9883 extracted from Fw32_default_color_map.
9884 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
9886 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
9888 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
9890 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
9892 * keyboard.c (test_undefined): New function (bug#9751).
9893 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
9895 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
9897 * sysdep.c (init_sys_modes): Fix the check for the controlling
9898 terminal (Bug#6649).
9900 2011-10-20 Eli Zaretskii <eliz@gnu.org>
9902 * dispextern.h (struct bidi_it): New member next_en_type.
9904 * bidi.c (bidi_line_init): Initialize the next_en_type member.
9905 (bidi_resolve_explicit_1): When next_en_pos is valid for the
9906 current character, check also for next_en_type being WEAK_EN.
9907 (bidi_resolve_weak): Don't enter the expensive loop if the current
9908 position is before next_en_pos. Record the bidi type of the first
9909 non-ET, non-BN character we find, in addition to its position.
9910 (bidi_level_of_next_char): Invalidate next_en_type when
9911 next_en_pos is over-stepped.
9913 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
9915 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
9916 * editfns.c: Rewrite current-time-zone so that it invokes
9917 the equivalent of (format-time-string "%Z") to get the time zone name.
9918 This fixes a bug when the time zone name contains characters that
9919 need converting from the system time locale to Emacs internal format.
9920 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9921 that patch fixed format-time-string to do the conversion, but
9922 I forgot to fix current-time-zone.
9923 (format_time_string): New function, containing most of
9924 what Fformat_time_string used to contain.
9925 (Fformat_time_string): Rewrite in terms of format_time_string.
9926 This doesn't change this function's behavior.
9927 (current-time-zone): Rewrite to use format_time_string.
9928 This fixes the bug reported by Michael Schierl in
9929 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9930 Jason Rumney's 2007-06-07 change worked around this bug, but
9932 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9934 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9936 * xdisp.c (start_display): If the character at POS is displayed
9937 via a display vector, reset IT->current.dpvec_index to zero.
9938 (try_window_reusing_current_matrix): If a line ends in a display
9939 vector or the next line starts in a display vector, continue
9940 redrawing the window even though the character position of
9941 start_row was reached.
9944 2011-10-18 Chong Yidong <cyd@gnu.org>
9946 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9947 with nobreak-char-display too.
9949 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9951 Fix part 3 of bug#9771.
9952 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9953 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9954 non-neutral characters if the current character is a paragraph
9955 separator (a.k.a. Newline). This avoids running the same
9956 expensive loop twice, once when we consume the preceding newline
9957 and the other time when the line actually needs to be displayed.
9958 Avoid the loop when we see neutrals on the base embedding level
9959 following a character whose directionality is the same as the
9960 paragraph's. This avoids running the expensive loop when a line
9961 ends in a long sequence of neutrals, like control characters.
9962 Add assertion against STRONG_AL type. Slightly rearrange code
9963 that determines the type of a neutral given the first non-neutral
9965 (bidi_level_of_next_char): Set next_en_pos to zero when
9966 invalidating its info.
9968 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9970 * xdisp.c (push_display_prop): Determine whether to record string
9971 or buffer position by IT->string, not by IT->method. Allow
9972 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9973 (move_it_vertically_backward): Don't look for character position
9974 immediately after the newline when in a continuation line.
9977 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9979 * window.c (coordinates_in_window): Rewrite and delabelize
9980 vertical border check. (Bug#5357) (Bug#9618)
9982 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9984 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9985 errors in XSetWindowBorder (bug#9310).
9987 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9989 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9990 avoid crash when xmalloc overrun checking is enabled.
9992 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9994 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9995 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9996 cursor motion with <left> and <right> arrow keys.
9998 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9999 some callers set that themselves.
10001 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10003 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
10004 display string and the previous row comes from the same string and
10005 is empty. (Bug#9739) (Bug#9738)
10007 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
10009 * doc.c (get_doc_string): Encode file name (bug#9735).
10011 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10013 * bidi.c (bidi_level_of_next_char):
10014 * xdisp.c (get_visually_first_element): Remove old incorrect
10015 comments regarding the Unicode Line Separator character.
10017 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
10019 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
10021 * alloc.c (Fgc_status): Do not access beyond zombies array
10022 boundary if nzombies > MAX_ZOMBIES.
10023 * alloc.c (dump_zombies): Add missing format specifier.
10025 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
10027 * xdisp.c (set_cursor_from_row): Simplify conditionals,
10028 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
10030 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
10031 Some packages use them to denote characters with modifiers.
10033 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
10035 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
10036 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
10037 matching a pp-number. Rename parameter var to var1.
10039 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
10041 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
10043 2011-10-08 Glenn Morris <rgm@gnu.org>
10045 * callint.c (Fcall_interactively): Give a more explicit error for the
10046 'c' case with a non-character input. (Bug#8479)
10048 2011-10-08 Eli Zaretskii <eliz@gnu.org>
10050 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
10052 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
10053 lines that are hscrolled on the left.
10055 * dispnew.c (buffer_posn_from_coords): Account for a possible
10056 presence of header-line. (Bug#4426)
10058 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
10060 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
10061 Don't advertise functionality which we discourage or doesn't work.
10063 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
10065 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
10066 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
10067 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
10068 this makes Emacs dump core during garbage collection on rare
10069 occasions. sizeof is obviously inferior to offsetof here, so
10070 stick with offsetof.
10071 (GC_POINTER_ALIGNMENT): New macro.
10072 (mark_memory): Omit 3rd (offset) arg; caller changed.
10073 Don't assume EMACS_INT alignment is the same as pointer alignment.
10075 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
10077 * keyboard.c (read_key_sequence_remapped): New var.
10078 (read_key_sequence): Compute remapping in the right buffer.
10079 (command_loop_1): Use read_key_sequence's remapping directly.
10081 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
10083 * dired.c (file_name_completion): Don't expand file name.
10084 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
10085 before checking file name handler.
10087 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
10088 they've been requested explicitly (bug#9591).
10090 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
10092 * keymap.c (Fsingle_key_description): Use make_specified_string
10093 instead of build_string to build string from push_key_description.
10096 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10098 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
10099 This fixes a Y2038 bug on 64-bit hosts.
10100 * buffer.c (reset_buffer):
10101 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
10102 (Fclear_buffer_auto_save_failure):
10103 Use 0, not -1, to represent an unset failure time, since time_t
10104 might not be signed.
10106 Remove dependency on glibc malloc internals.
10107 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10108 Move back here from lisp.h, but with their new implementations.
10109 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10110 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
10111 * charset.c (charset_table_init): New static var.
10112 (syms_of_charset): Use it instead of xmalloc. This removes a
10113 dependency on glibc malloc internals. See Eli Zaretskii's comment in
10114 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
10115 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10116 Move back to alloc.c.
10117 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10118 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
10120 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
10122 * nsterm.m (windowDidResize): Call x_set_window_size only when
10123 ns_in_resize is true. Otherwise set pixelwidth/height and
10124 call change_frame_size (Bug#9628).
10126 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10128 Port --enable-checking=all to Fedora 14 x86-64.
10129 * charset.c (syms_of_charset): Also account for glibc malloc's
10130 internal overhead when calculating the initial malloc maximum.
10132 Port --enable-checking=all to Fedora 14 x86.
10133 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10135 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
10136 (overrun_check_realloc, overrun_check_free):
10137 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
10138 That way, xmalloc returns a properly-aligned pointer even if
10139 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
10140 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
10141 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
10142 into account when calculating the initial malloc maximum.
10143 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10144 Move here from alloc.c, so that charset.c can use it too.
10145 Properly align; the old code wasn't right for common 32-bit hosts
10146 when configured with --enable-checking=all.
10147 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10148 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
10150 2011-09-29 Eli Zaretskii <eliz@gnu.org>
10152 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
10155 2011-09-28 Eli Zaretskii <eliz@gnu.org>
10157 * xdisp.c (compute_display_string_end): If there's no display
10158 string at CHARPOS, return -1.
10160 * bidi.c (bidi_fetch_char): When compute_display_string_end
10161 returns a negative value, treat the character as a normal
10162 character not covered by a display string. (Bug#9624)
10164 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
10166 * lread.c (Fread_from_string): Fix typo in docstring.
10168 2011-09-27 Eli Zaretskii <eliz@gnu.org>
10170 * xdisp.c (handle_invisible_prop): If invisible text ends on a
10171 newline, reseat the iterator instead of bidi-iterating there one
10172 character at a time. (Bug#9610)
10173 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
10174 TO_CHARPOS if the bidi iterator is at base embedding level.
10176 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
10178 * lread.c (readevalloop): Use correct code for NBSP.
10179 (read1): Likewise. (Bug#9608)
10181 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
10183 * dbusbind.c (Fdbus_register_signal): When service is not
10184 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
10186 2011-09-25 Glenn Morris <rgm@gnu.org>
10188 * buffer.c (truncate-lines): Doc fix.
10190 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
10192 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
10193 (Fset_window_next_buffers): Doc fix.
10195 2011-09-24 Glenn Morris <rgm@gnu.org>
10197 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
10199 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
10201 Fix minor problems found by static checking.
10202 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
10203 * indent.c (Fvertical_motion): Fix == vs = typo.
10205 2011-09-24 Eli Zaretskii <eliz@gnu.org>
10207 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
10208 Default value is now t. Doc fix.
10210 * indent.c (Fvertical_motion): Compute and apply the overshoot
10211 logic when moving up, not only when moving down. Fix the
10212 confusing name and values of the it_overshoot_expected variable;
10213 logic changes accordingly. (Bug#9254) (Bug#9549)
10215 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
10216 CHARPOS is covered by a display string which includes newlines.
10217 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
10218 is covered by a display string with embedded newlines.
10220 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
10222 * dbusbind.c (Fdbus_register_signal): Add match rule to
10223 Vdbus_registered_objects_table. (Bug#9581)
10224 (Fdbus_register_method, Vdbus_registered_objects_table):
10227 2011-09-24 Jim Meyering <meyering@redhat.com>
10229 do not ignore write error for any output size
10230 The previous change was incomplete.
10231 While it makes emacs --batch detect the vast majority of stdout
10232 write failures, errors were still ignored whenever the output size is
10233 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
10234 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
10235 && echo FAIL: ignored write error
10236 FAIL: ignored write error
10237 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
10238 && echo FAIL: ignored write error
10239 FAIL: ignored write error
10240 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
10242 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
10244 * emacs.c (Fkill_emacs): In noninteractive mode exit
10245 non-successfully if a write error occurred on stdout. (Bug#9574)
10247 2011-09-21 Eli Zaretskii <eliz@gnu.org>
10249 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
10252 * dispextern.h (struct it): Update the comment documenting what
10255 2011-09-20 Eli Zaretskii <eliz@gnu.org>
10257 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
10258 a display string, extend search for cursor position to end of row.
10259 (find_row_edges): If the row ends in a newline from a display
10260 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
10261 Handle the case of a display string with multiple newlines.
10262 (Fcurrent_bidi_paragraph_direction): Fix search for previous
10263 non-empty line. Fixes confusing cursor motion with arrow keys at
10264 the beginning of a line that starts with whitespace.
10266 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10268 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
10271 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
10273 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
10274 boolean (Bug#9154).
10276 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10278 * xdisp.c (display_line): Record maximum and minimum buffer
10279 positions even if no glyphs were produced (e.g., by a zero-width
10280 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
10281 buffer positions that will be removed from the glyph row because
10283 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
10284 column is beyond frame width: don't subtract 1 "pixel" when
10285 computing width of the stretch.
10286 (reseat_at_next_visible_line_start): Undo the change made on
10287 2011-09-17 that saved paragraph information and restored it after
10288 the call to `reseat'. (Bug#9545)
10290 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10292 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
10293 and turn window cursor on if cleared (Bug#9415).
10295 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
10297 * search.c (boyer_moore): Take unibyte characters from pattern
10298 literally. (Bug#9458)
10300 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10302 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
10304 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
10306 Fix minor problem found by static checking.
10307 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
10308 initialized, to pacify gcc -Wuninitialized.
10310 * fileio.c: Report proper errno when syscall falls.
10311 (Finsert_file_contents): Save and restore errno,
10312 so that report_file_error outputs the correct diagnostic.
10313 (Fwrite_region) [CLASH_DETECTION]: Likewise.
10315 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10317 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
10319 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10321 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
10322 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
10324 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10326 * xdisp.c (reseat_at_next_visible_line_start): Keep information
10327 about the current paragraph and restore it after the call to reseat.
10329 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
10330 (bidi_find_paragraph_start): Search back for paragraph beginning
10331 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
10332 (bidi_move_to_visually_next): Only trigger paragraph-related
10333 computations when the last character is a newline or at EOB, not
10334 just any NEUTRAL_B. (Bug#9470)
10336 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
10337 truncated lines if point is covered by a display string. (Bug#9524)
10339 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
10341 * xselect.c: Relax test for outgoing X longs (Bug#9498).
10342 (cons_to_x_long): New function.
10343 (lisp_data_to_selection_data): Use it. Correct the test for
10344 short-versus-long data; it was negated. Break out of vector
10345 loop, for efficiency, when a long datum is discovered.
10347 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
10349 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
10351 2011-09-16 Eli Zaretskii <eliz@gnu.org>
10353 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
10354 GCC PR/17406) by declaring this function with external scope.
10356 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10358 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
10359 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
10361 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
10363 * editfns.c (Fformat): Correctly handle text properties on "%%".
10365 2011-09-15 Eli Zaretskii <eliz@gnu.org>
10367 * xterm.c (x_draw_composite_glyph_string_foreground):
10368 * w32term.c (x_draw_composite_glyph_string_foreground):
10369 * term.c (encode_terminal_code):
10370 * composite.c (composition_update_it, get_composition_id):
10371 * xdisp.c (get_next_display_element)
10372 (fill_composite_glyph_string): Add comments about special meaning
10373 of TAB characters in a composition.
10375 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10377 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
10378 This occurs when processing a multibyte format.
10379 Problem reported by Wolfgang Jenker.
10381 2011-09-15 Johan Bockgård <bojohan@gnu.org>
10383 * xdisp.c (try_cursor_movement): Only check for exact match if
10384 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
10386 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10388 Remove unused external symbols.
10389 * dispextern.h (calc_pixel_width_or_height): Remove decl.
10390 * xdisp.c (calc_pixel_width_or_height): Now static.
10391 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
10392 * indent.c (check_display_width):
10393 * w32term.c: Fix comment to match code.
10394 * xterm.c, xterm.h (x_catching_errors): Remove.
10396 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10398 * xselect.c: Use signed conversions more consistently (Bug#9498).
10399 (selection_data_to_lisp_data): Assume incoming selection data are
10400 signed integers, not unsigned. This is to be consistent with
10401 outgoing selection data, which was modified to use signed integers
10402 in as part of the fix to Bug#9196 in response to Jan D.'s comment
10403 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
10404 expects long, not unsigned long.
10406 2011-09-14 Eli Zaretskii <eliz@gnu.org>
10408 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
10409 computation of loop end. Reported by Johan Bockgård
10412 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
10414 * frame.c (Fother_visible_frames_p): Function deleted.
10416 2011-09-12 Eli Zaretskii <eliz@gnu.org>
10418 * indent.c (compute_motion): Process display vector front to back
10419 rather than the other way around. (Bug#2496)
10421 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
10423 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
10425 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
10427 * minibuf.c (Fread_from_minibuffer): Doc fix.
10429 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10431 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
10432 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
10434 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
10436 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
10437 value for non-existent files.
10439 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10441 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10442 set its "size" to -1. This will set the modtime_size field of
10443 the corresponding buffer to -1, which is what
10444 verify-visited-file-modtime expects for files that do not exist.
10447 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
10449 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10451 * lisp.h: ... from here. push_key_description is no longer
10452 defined in keyboard.c, so its declaration should not be in
10453 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10454 logically belongs with push_key_description.
10456 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10458 * buffer.h: Include <sys/types.h> instead of <time.h>.
10459 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
10460 Problem reported by Herbert J. Skuhra.
10462 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
10464 * xml.c (parse_region): Make the parsing work for
10465 non-comment-starting XML files again (bug#9144).
10467 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
10469 * image.c (gif_load): Fix calculation of bottom and right corner.
10472 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10474 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10475 redisplay in small windows.
10477 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10479 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10481 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10483 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10484 Operate on live windows only.
10486 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10488 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10490 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10492 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10493 only under bidi iteration.
10495 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10497 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10499 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10501 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10502 Without this fix, the command to link temacs failed due to an
10503 undefined symbol __builtin_isnan. This is because
10504 /usr/include/iso/math_c99.h #defines isnan(x) to
10505 __builtin_isnan(x), but the bundled gcc, which identifies itself
10506 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10508 * floatfns.c (isnan): #undef, and then #define to a clone of
10510 (Fisnan): Always define, since it's always available now.
10511 (syms_of_floatfns): Always define isnan at the Lisp level.
10513 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10515 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10517 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10519 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10520 The previous code assumed that file offsets (off_t values) fit in
10521 EMACS_INT variables, which is not true on typical 32-bit hosts.
10522 The code messed up by falsely reporting buffer overflow in cases
10523 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10524 when "big" contains more than 2**29 bytes, even though this
10525 inserts just one byte and does not overflow the buffer.
10526 (Finsert_file_contents): Store file offsets as off_t
10527 values, not as EMACS_INT values. Check for overflow when
10528 converting between EMACS_INT and off_t. When checking for
10529 buffer overflow or for overlap, take the offsets into account.
10530 Don't use EMACS_INT for small values where int suffices.
10531 When checking for overlap, fix a typo: ZV was used where
10532 ZV_BYTE was intended.
10533 (Fwrite_region): Don't assume off_t fits into 'long'.
10534 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10536 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10538 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10540 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10542 sprintf-related integer and memory overflow issues (Bug#9412).
10544 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10545 (esprintf, exprintf, evxprintf): New functions.
10546 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10547 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10548 (modify_event_symbol): Do not assume that the length of
10549 name_alist_or_stem is safe to alloca and fits in int.
10550 (Fexecute_extended_command): Likewise for function name and binding.
10551 (Frecursion_depth): Wrap around reliably on integer overflow.
10552 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10553 since some callers pass EMACS_INT values.
10554 (Fsingle_key_description): Don't crash if symbol name contains more
10555 than MAX_ALLOCA bytes.
10556 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10557 (get_minibuffer): Arg is now EMACS_INT, not int.
10558 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10559 (esprintf, exprintf, evxprintf): New decls.
10560 * window.h (command_loop_level, minibuf_level): Reflect API changes.
10562 * dbusbind.c (signature_cat): New function.
10563 (xd_signature, Fdbus_register_signal):
10564 Do not overrun buffer; instead, report string overflow.
10566 * dispnew.c (add_window_display_history): Don't overrun buffer.
10567 Truncate instead; this is OK since it's just a log.
10569 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10570 even if the time zone offset is outlandishly large.
10571 Don't mishandle offset == INT_MIN.
10573 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10574 when creating daemon; the previous buffer-overflow check was incorrect.
10576 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10577 which has the guts of the old verror function.
10579 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10580 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10582 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10583 (font_unparse_xlfd): Don't blindly alloca long strings.
10584 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10585 fits in int, when using sprintf. Use single snprintf to count
10586 length of string rather than counting it via multiple sprintfs;
10587 that's simpler and more reliable.
10588 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10589 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10590 sprintf, in case result does not fit in int.
10592 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10593 (fontset_from_font): Print it.
10595 * frame.c (tty_frame_count): Now printmax_t, not int.
10596 (make_terminal_frame, set_term_frame_name): Print it.
10597 (x_report_frame_params): In X, window IDs are unsigned long,
10598 not signed long, so print them as unsigned.
10599 (validate_x_resource_name): Check for implausibly long names,
10600 and don't assume name length fits in 'int'.
10601 (x_get_resource_string): Don't blindly alloca invocation name;
10602 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10605 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10606 (xg_check_special_colors, xg_set_geometry):
10607 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10609 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10610 Use esprintf, not sprintf, in case result does not fit in int.
10612 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10613 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10614 it as a large positive number.
10615 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10616 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10618 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10619 in case result does not fit in int.
10621 * print.c (float_to_string): Detect width overflow more reliably.
10622 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10623 buffer overrun. Don't assume list length fits in 'int'. Treat
10624 print length of 0 as 0, not as infinity; to be consistent with other
10625 uses of print length in this function. Don't overflow print length
10626 index. Don't assume hash table size fits in 'long', or that
10627 vectorlike size fits in 'unsigned long'.
10629 * process.c (make_process): Use printmax_t, not int, to format
10630 process-name gensyms.
10632 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10634 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10635 to avoid potential buffer overrun.
10637 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10638 if X resource line is longer than 512 bytes.
10640 * xfns.c (x_window): Make sprintf buffer a bit bigger
10641 to avoid potential buffer overrun.
10643 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10645 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10647 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10649 Integer overflow fixes for scrolling, etc.
10650 Without these, Emacs silently mishandles large integers sometimes.
10651 For example, "C-u 4294967297 M-x recenter" was treated as if
10652 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10654 * xdisp.c (try_window_id): Check Emacs fixnum range before
10655 converting to 'int'.
10657 * window.c (window_scroll_line_based, Frecenter):
10658 Check that an Emacs fixnum is in range before assigning it to 'int'.
10659 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10660 values converted from Emacs fixnums.
10661 (Frecenter): Don't wrap around a line count if it is out of 'int'
10662 range; instead, treat it as an extreme value.
10663 (Fset_window_configuration, compare_window_configurations):
10664 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10666 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10667 that can exceed INT_MAX. Check that EMACS_INT value is in range
10668 before assigning it to the (possibly-narrower) index.
10669 (match_limit): Don't assume that a fixnum can fit in 'int'.
10671 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10674 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10675 (Fvertical_motion): Don't wrap around LINES values that don't fit
10676 in 'int'. Instead, treat them as extreme values. This is good
10677 enough for windows, which can't have more than INT_MAX lines anyway.
10679 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10681 * Require libxml/parser.h to avoid compilation warning.
10683 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10685 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10686 since this reportedly can destroy thread storage.
10688 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10690 * syntax.c (find_defun_start): Update all cache variables if
10691 exiting early (Bug#9401).
10693 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10695 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10697 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10698 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10699 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10701 * term.c (tty_append_glyph): New function.
10702 (produce_stretch_glyph): Static function and its prototype deleted.
10704 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10707 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10709 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10710 when checking :margin (Bug#9390).
10711 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10712 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10713 so that the name doesn't mislead. All uses changed.
10715 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10717 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
10720 2011-08-27 Eli Zaretskii <eliz@gnu.org>
10722 * xdisp.c (move_it_to): Don't bail out early when reaching
10723 position beyond to_charpos, if we are scanning backwards.
10724 (move_it_vertically_backward): When DY == 0, make sure we get to
10725 the first character in the line after the newline.
10727 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10729 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10730 (ccl_driver): Do not generate an out-of-range pointer.
10731 (Fccl_execute_on_string): Remove unnecessary check for
10732 integer overflow, noted by Stefan Monnier in
10733 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10734 Remove a FIXME that didn't need fixing.
10735 Simplify the newly-introduced buffer reallocation code.
10737 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10739 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10741 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10743 Integer and memory overflow issues (Bug#9196).
10745 * doc.c (get_doc_string): Rework so that
10746 get_doc_string_buffer_size is the actual buffer size, rather than
10747 being 1 less than the actual buffer size; this makes xpalloc more
10750 * image.c (x_allocate_bitmap_record, cache_image):
10751 * xselect.c (Fx_register_dnd_atom):
10752 Simplify previous changes by using xpalloc.
10754 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10755 since either will do and ptrdiff_t is convenient with xpalloc.
10757 * charset.c (charset_table_size)
10758 (struct charset_sort_data.priority): Now ptrdiff_t.
10759 (charset_compare): Don't overflow if priorities differ greatly.
10760 (Fsort_charsets): Don't assume list length fits in int.
10761 Check for size-calculation overflow when allocating sort data.
10762 (syms_of_charset): Allocate an initial charset table that is
10763 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10765 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10767 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10768 The actual value is always <= INT_MAX, and leaving it unsigned made
10769 overflow checking harder.
10771 * dispextern.h (struct glyph_matrix.rows_allocated)
10772 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10773 with xpalloc. The values are still always <= INT_MAX.
10775 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10777 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10778 (SAFE_NALLOCA): New macro.
10780 * region-cache.c (struct boundary.pos, find_cache_boundary)
10781 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10782 (set_cache_region, invalidate_region_cache)
10783 (revalidate_region_cache, know_region_cache, region_cache_forward)
10784 (region_cache_backward, pp_cache):
10785 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10786 so that ptrdiff_t * can be passed to xpalloc.
10787 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
10788 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

10806 because xmalloc/xrealloc may not return.
10807 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10808 now that we have proper integer overflow checking.
10809 (record_overlay_string, overlay_strings): Catch overflows when
10810 calculating size of overlay_str_buf.
10812 * callproc.c (Fcall_process): Check for size overflow when
10813 calculating size of args2.
10814 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.

10816 require adding more-complicated checks.
10818 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10819 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

10859 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10861 * emacs.c (main): Do not reallocate argv, since there is a null at
10862 the end that can be overwritten, and this way there's no need to
10863 worry about size-calculation overflow.
10864 (sort_args): Check for size-calculation overflow.
10866 * eval.c (init_eval_once, grow_specpdl): Don't update size until

10872 Check for integer overflow.
10873 (x_set_alpha): Do not assume XINT fits in int.
10875 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10876 This is for the members text_lines, text_cols, total_lines, total_cols,
10877 where the system imposes an 'int' limit.
10879 * fringe.c (Fdefine_fringe_bitmap):
10880 Don't update size until alloc works.

10885 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
10886 Check for size-calculation overflow.
10887 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10888 do, as we prefer signed integers.
10889 (id_to_widget.max_size, id_to_widget.used)
10890 (xg_store_widget_in_map, xg_remove_widget_from_map)

10895 * gtkutil.h: Change prototypes to match the above.
10897 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

10944 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
10945 for command line length. Do not attempt to address one before the
10946 beginning of an array, as that's not portable.

10981 (Fx_change_window_property): Use ptrdiff_t, not int, to count
10982 sizes, since they can exceed INT_MAX in size. Check for size

10993 (X_LONG_MIN): New macros.
10994 Use them to make the following changes clearer.
10995 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
10996 This change doesn't affect the value now, but it may help remind
10997 future maintainers not to raise the value too much later.
10998 (SELECTION_QUANTUM): Remove, replacing with ...
10999 (selection_quantum): ... new function, which avoids overflow.
11001 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
11002 assumption that selection length fits in 'int'.

11019 Don't store size until memory allocation succeeds.
11020 (x_get_window_property): Plug memory leak on memory exhaustion.
11021 Don't double-block input; malloc is safe here. Don't assume 2**34
11022 - 4 fits in unsigned long. Add an xassert to check
11023 XGetWindowProperty overflow. Be more careful about overflow
11024 calculations, and distinguish size from memory overflow better.
11025 (receive_incremental_selection): When tracing, don't assume
11026 unsigned int is less than INT_MAX.
11027 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

11030 in the range -65535 through -1 fit in an X unsigned short.
11031 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
11032 result parameters unless successful. Rely on cons_to_unsigned
11033 to report problems with elements; the old code wasn't right anyway.
11034 (x_check_property_data): Check for int overflow; we cannot use
11035 a wider type due to X limits.

11068 * lisp.h (hash_lookup, hash_put):
11069 * minibuf.c (Ftest_completion):
11070 Use ptrdiff_t for hash table indexes, not int (which is too
11071 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
11072 32-bit --with-wide-int hosts).
11074 * charset.c (Fdefine_charset_internal): Check for integer overflow.
11075 Add a FIXME comment about memory leaks.

11083 with outlandish widths.
11084 * character.h (sanitize_tab_width): Rename from sanitize_width,

11104 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
11105 (x_send_scroll_bar_event): Likewise. Check that the size does not
11106 exceed limits imposed by XClientMessageEvent, as well as the usual
11107 ptrdiff_t and size_t limits.
11109 * keyboard.c: Overflow, signedness and related fixes.
11110 (make_lispy_movement): Use same integer type in forward decl
11111 that is used in the definition.

11113 Change bufsize argument back to int, undoing my 2011-03-30 change.
11114 We prefer signed types, and int is wide enough here.
11115 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
11116 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
11117 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
11118 length, not size_t. Use ptrdiff_t for index, not int.
11119 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
11120 possibility of integer overflow.

11148 Prefer int to unsigned where either will do.
11149 (tiff_handler): New function, combining the cores of the
11150 old tiff_error_handler and tiff_warning_handler.
11151 This function is rewritten to use vsnprintf and thereby avoid
11152 stack buffer overflows. It uses only the features of vsnprintf
11153 that are common to both POSIX and native Microsoft.
11154 (tiff_error_handler, tiff_warning_handler): Use it.
11155 (tiff_load, gif_load, imagemagick_load_image):
11156 Don't assume :index value fits in 'int'.

11159 the integer types that MagickCropImage accepts. Don't assume
11160 Vimagemagick_render_type has a nonnegative value. Don't assume
11161 size_t fits in 'long'.
11162 (gs_load): Use printmax_t to print the widest integers possible.

11165 2011-08-26 Eli Zaretskii <eliz@gnu.org>
11167 * xdisp.c (redisplay_window): Don't force window start if point

11175 handle_single_display_spec, not just 1 or zero.
11176 (handle_single_display_spec): If the display spec is of the form
11177 `(space ...)', and specifies display in the text area, return 2
11179 (try_cursor_movement): Check for the need to scroll more
11180 accurately, and prefer exact match for point under bidi.
11181 Don't advance `row' beyond the last row of the window.

11198 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
11199 buffers, return left-to-right.
11200 (set_cursor_from_row): Consider candidate row a win if its glyph
11201 represents a newline and point is on that newline. Fixes cursor
11202 positioning on the newline at EOL of R2L text within L2R
11203 paragraph, and vice versa.
11204 (try_cursor_movement): Check continued rows, in addition to
11205 continuation rows. Fixes unwarranted scroll when point enters a
11206 continued line of R2L text within an L2R paragraph, or vice versa.
11207 (cursor_row_p): Consider the case of point being equal to
11208 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
11209 from the end of a short line to the beginning of a continued line
11210 of R2L text within L2R paragraph.
11211 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

11229 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
11230 extra slot even if the purpose is char-code-property-table.
11232 2011-08-23 Eli Zaretskii <eliz@gnu.org>
11234 * xdisp.c (redisplay_window): When computing centering_position,
11235 account for the height of the header line. (Bug#8874)
11237 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
11238 instead of CHAR_TO_BYTE. Fixes a crash when a completion
11239 candidate is selected by the mouse, and that candidate has a
11240 composed character under the mouse.
11242 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
11243 coordinates reported by pos-visible-in-window-p for a composed
11244 character in column zero.
11246 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

11254 composed buffer positions.
11256 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
11258 * image.c (gif_load): Don't assume that each subimage has the same
11259 dimensions as the base image. Handle disposal method that is
11260 "undefined" by the gif spec (Bug#9335).
11262 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
11264 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

11269 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
11270 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
11271 from an Org mode buffer to a Speedbar frame.
11273 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
11274 a composition, take its buffer position from IT->cmp_it.charpos.
11275 Fixes cursor positioning at the beginning of a line that begins
11276 with a composed character.
11278 2011-08-18 Eli Zaretskii <eliz@gnu.org>
11280 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
11281 character bidirectional type, use STRONG_L instead. Fixes crashes
11282 in a buffer produced by `describe-categories'.
11284 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
11285 members before the level stack, so they would be saved and
11286 restored when copying iterator state. Fixes incorrect reordering
11287 around TABs covered by display properties.
11289 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
11291 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

11296 (internal_condition_case_2, internal_condition_case_n):
11297 Remove unnecessary aborts (Bug#9081).
11299 2011-08-17 Eli Zaretskii <eliz@gnu.org>
11301 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
11302 has no `load' handler, try opening the file locally. (Bug#9311)
11304 2011-08-16 Ken Brown <kbrown@cornell.edu>
11306 * gmalloc.c: Expand comment.
11308 2011-08-16 Eli Zaretskii <eliz@gnu.org>

11324 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
11325 in the static heap.
11326 [CYGWIN] (special_realloc): New function.
11327 (_realloc_internal_nolock) [CYGWIN]: Use the new function on

11359 2011-08-14 Eli Zaretskii <eliz@gnu.org>
11361 * xdisp.c (move_it_in_display_line_to): Don't invoke
11362 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
11363 ppos_it. Fixes vertical cursor motion when line beginning is
11364 covered by an image. (Bug#9296)
11366 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
11368 * nsterm.h (ns_run_ascript): Declare.

11372 (ns_run_ascript): New function.
11373 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
11374 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
11375 the event loop. Get status from as_status (Bug#7276).
11377 * nsterm.m (sendEvent): If event is NSApplicationDefined and
11378 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
11379 the event loop (Bug#7276).
11381 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
11383 * gnutls.c (QCgnutls_bootprop_priority)

11385 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
11386 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
11387 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
11388 (QCgnutls_bootprop_verify_hostname_error)

11404 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
11405 (Fnetwork_interface_list): Allocate in increments of bytes instead
11406 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
11407 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
11409 (struct ifflag_def): notrailers is smart on OSX.
11410 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
11411 Get hardware address with getifaddrs if available.
11413 2011-08-12 Eli Zaretskii <eliz@gnu.org>
11415 * xdisp.c (iterate_out_of_display_property): xassert that
11416 IT->position is set to within IT->object's boundaries. Break from
11417 the loop as soon as EOB is reached; avoids infloops in redisplay
11418 when IT->position is set up wrongly due to some bug.
11419 Set IT->current to match the bidi iterator unconditionally.
11420 (push_display_prop): Allow GET_FROM_STRING as IT->method on
11421 entry. Force push_it to save on the stack the current
11422 buffer/string position, to be restored by pop_it. Fix flags in
11423 the iterator structure wrt the object coming from a display
11424 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
11425 properties. (Bug#9284)
11427 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
11429 * fontset.c (fontset_get_font_group): Add proper type checks.

11442 no-display-properties-and-no-overlays under bidi display.
11443 Set disp_pos in the bidi iterator to avoid searches for display
11444 properties and overlays.
11446 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
11448 * editfns.c (Fset_time_zone_rule): Document relationship with the

11457 restore_point_unwind (Bug#5984).
11459 2011-08-07 Juri Linkov <juri@jurta.org>
11461 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
11462 to show the arg `TIME' instead of `TIMEVAL'.
11464 2011-08-06 Eli Zaretskii <eliz@gnu.org>
11466 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
11467 display property strides EOL and includes a newline, as in
11468 longlines-mode. (Bug#9254)
11469 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
11470 word-wrap under bidirectional display. (Bug#9224)
11472 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
11473 is non-zero, even if the data buffer is NULL. Fixes a crash in
11474 vertical-motion with longlines-mode. (Bug#9254)
11476 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11478 * bidi.c <bidi_cache_total_alloc>: Now static.
11479 (bidi_initialize): Initialize bidi_cache_total_alloc.
11481 * xdisp.c (display_line): Release buffer allocated for shelved bidi
11484 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
11485 amount allocated this far in `bidi_cache_total_alloc'.
11486 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
11487 non-zero, only free the data buffer without restoring the cache
11488 contents. All callers changed.
11490 * dispextern.h (bidi_unshelve_cache): Update prototype.
11492 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
11493 (move_it_in_display_line, move_it_to)
11494 (move_it_vertically_backward, move_it_by_lines): Replace the call
11495 to xfree to an equivalent call to bidi_unshelve_cache.
11496 (move_it_in_display_line_to): Fix logic of returning
11497 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
11499 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11501 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
11502 came from a string character with a `cursor' property. (Bug#9229)
11504 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11506 * Makefile.in (LIB_PTHREAD): New variable.
11507 (LIBES): Add LIB_PTHREAD (Bug#9216).
11509 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
11510 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
11512 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
11514 * regex.c (re_iswctype): Remove some redundant boolean conversions.
11516 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11518 * xterm.c (x_find_topmost_parent): New function.
11519 (x_set_frame_alpha): Find topmost parent window with
11520 x_find_topmost_parent and set the property there also (bug#9181).
11521 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
11523 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
11525 * callproc.c (Fcall_process): Avoid vfork clobbering
11526 the local vars buffer, coding_systems, current_dir.

11534 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
11535 so that it is not optimized away.
11537 * xdisp.c (compute_display_string_pos): Remove unused local.
11539 2011-08-02 Eli Zaretskii <eliz@gnu.org>
11541 Fix slow cursor motion and scrolling in large buffers with
11542 selective display, like Org Mode buffers. (Bug#9218)

11546 * xdisp.c: Remove one-slot cache of display string positions.
11547 (compute_display_string_pos): Accept an additional argument

11549 for a display string or property. If found, set DISP_PROP_P
11552 * bidi.c (bidi_fetch_char): Accept an additional argument
11553 DISP_PROP_P, and pass it to compute_display_string_pos.
11554 Only handle text covered by a display string if DISP_PROP_P is returned
11555 non-zero. All callers of bidi_fetch_char changed.
11557 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
11559 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
11561 2010-12-03 Don March <don@ohspite.net>
11563 * keymap.c (Fdefine_key): Fix non-prefix key error message when
11564 last character M-[char] is translated to ESC [char] (bug#7541).
11566 2011-08-02 Kenichi Handa <handa@m17n.org>
11568 * lisp.h (uniprop_table): Extern it.
11570 * chartab.c (uniprop_table): Make it non-static.
11572 2011-08-01 Eli Zaretskii <eliz@gnu.org>
11574 * xdisp.c (forward_to_next_line_start): Accept additional argument
11575 BIDI_IT_PREV, and store into it the state of the bidi iterator had
11577 (reseat_at_next_visible_line_start): Use the bidi iterator state
11578 returned by forward_to_next_line_start to restore the state of
11579 it->bidi_it after backing up to previous newline. (Bug#9212)
11581 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
11583 * regex.c (re_comp): Protoize.
11584 (re_exec): Fix return type.
11585 (regexec): Fix type of `ret'. (Bug#9203)
11587 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11589 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
11590 This is needed if max-image-size is a floating-point number.
11592 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11594 * print.c (print_object): Print empty symbol as ##.

11605 contents (Bug#9176).
11606 (EmacsTooltip -init): Remove bezels and add shadows to
11609 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
11610 or scroll bar (Bug#8470).
11612 * nsfont.m (nsfont_open): Remove assignment to voffset and

11616 * nsterm.h (nsfont_info): Remove voffset field.
11618 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11620 Implement strike-through and overline on NextStep (Bug#8863).
11622 * nsfont.m (nsfont_open): Use underline position provided by font,
11623 instead of hard-coded value of 2.
11624 (nsfont_draw): Call ns_draw_text_decoration instead.

11639 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11641 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11642 Without this fix, if a signal arrives just after memory fills up,
11643 'malloc' might be invoked reentrantly.
11645 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11646 In other words, assume that every image size is allowed, on non-X
11647 hosts. This assumption is probably wrong, but it lets Emacs compile.
11649 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11651 * regex.c (re_iswctype): Convert return values to boolean.

11655 * xdisp.c (compute_display_string_pos): Don't use cached display
11656 string position if the buffer had its restriction changed.
11659 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11661 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11663 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11665 Integer signedness and overflow and related fixes. (Bug#9079)
11667 * bidi.c: Integer size and overflow fixes.
11668 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
11669 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
11670 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11671 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11672 (bidi_find_other_level_edge):
11673 Use ptrdiff_t instead of EMACS_INT where either will do.
11674 This works better on 32-bit hosts configured --with-wide-int.
11675 (bidi_cache_ensure_space): Check for size-calculation overflow.
11676 Use % rather than repeated addition, for better worst-case speed.
11677 Don't set bidi_cache_size until after xrealloc returns, because it
11679 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11680 (bidi_cache_ensure_space): Also check that the bidi cache size
11681 does not exceed that of the largest Lisp string or buffer. See Eli
11682 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11684 * alloc.c (__malloc_size_t): Remove.
11685 All uses replaced by size_t. See Andreas Schwab's note
11686 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11688 * image.c: Improve checking for integer overflow.
11689 (check_image_size): Assume that f is nonnull, since
11690 it is always nonnull in practice. This is one less thing to
11691 worry about when checking for integer overflow later.
11692 (x_check_image_size): New function, which checks for integer
11693 overflow issues inside X.
11694 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11695 This removes the need for a memory_full check.
11696 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11697 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11698 (xbm_read_bitmap_data): Change locals back to 'int', since
11699 their values must fit in 'int'.
11700 (xpm_load_image, png_load, tiff_load):
11701 Invoke x_create_x_image_and_pixmap earlier,
11702 to avoid much needless work if the image is too large.
11703 (tiff_load): Treat overly large images as if
11704 x_create_x_image_and_pixmap failed, not as malloc failures.
11705 (gs_load): Use x_check_image_size.
11707 * gtkutil.c: Omit integer casts.
11708 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11709 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11711 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11713 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11714 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11715 would wrongly return t on a 64-bit host.
11717 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11718 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11719 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11720 and therefore cause GCC to emit a bogus diagnostic in some cases.
11722 * image.c: Integer signedness and overflow and related fixes.
11723 This is not an exhaustive set of fixes, but it's time to
11724 record what I've got.
11725 (lookup_pixel_color, check_image_size): Remove redundant decls.
11726 (check_image_size): Don't assume that arbitrary EMACS_INT values
11727 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11728 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11729 (tiff_load, imagemagick_load_image):
11730 Check for overflow in size calculations.
11731 (x_create_x_image_and_pixmap): Remove unnecessary test for
11732 xmalloc returning NULL; that can't happen.
11733 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11734 (xpm_color_bucket): Use better integer hashing function.
11735 (xpm_cache_color): Don't possibly over-allocate memory.
11736 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11737 (gif_memory_source):
11738 Use ptrdiff_t, not int or size_t, to record sizes.
11739 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11740 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11741 either works, as we prefer signed integers.
11742 (tiff_read_from_memory, tiff_write_from_memory):
11743 Return tsize_t, not size_t, since that's what the TIFF API wants.
11744 (tiff_read_from_memory): Don't fail simply because the read would
11745 go past EOF; instead, return a short read.
11746 (tiff_load): Omit no-longer-needed casts.
11747 (Fimagemagick_types): Don't assume size fits into 'int'.
11749 Improve hashing quality when configured --with-wide-int.
11750 * fns.c (hash_string): New function, taken from sxhash_string.
11751 Do not discard information about ASCII character case; this
11752 discarding is no longer needed.
11753 (sxhash-string): Use it. Change sig to match it. Caller changed.
11754 * lisp.h: Declare it.
11755 * lread.c (hash_string): Remove, since we now use fns.c's version.
11756 The fns.c version returns a wider integer if --with-wide-int is
11757 specified, so this should help the quality of the hashing a bit.
11759 * emacs.c: Integer overflow minor fix.
11760 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11761 Define only if GNU_LINUX.
11762 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11764 * dispnew.c: Integer signedness and overflow fixes.
11765 Remove unnecessary forward decls, that were a maintenance hassle.
11766 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11768 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11769 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11770 (prepare_desired_row, line_draw_cost):
11771 Use int, not unsigned, where either works.
11772 (save_current_matrix, restore_current_matrix):
11773 Use ptrdiff_t, not size_t, where either works.
11774 (init_display): Check for overflow more accurately, and without
11775 relying on undefined behavior.
11777 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11778 Remove, replacing with the new symbols in lisp.h. All uses changed.
11779 * fileio.c (make_temp_name):
11780 * filelock.c (lock_file_1, lock_file):
11781 * xdisp.c (message_dolog):
11782 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11783 Use pMd etc. instead.
11784 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11785 replacing the pWIDE etc. symbols removed from editfns.c.
11787 * keyboard.h (num_input_events): Now uintmax_t.
11788 This is (very slightly) less likely to mess up due to wraparound.
11791 * buffer.c: Integer signedness fixes.
11792 (alloc_buffer_text, enlarge_buffer_text):
11793 Use ptrdiff_t rather than size_t when either will do, as we prefer
11796 * alloc.c: Integer signedness and overflow fixes.
11797 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11798 (__malloc_size_t): Default to size_t, not to int.
11799 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11800 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11801 Prefer ptrdiff_t to size_t when either would do, as we prefer
11803 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11804 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11805 Now const. Initialize with values that are in range even if char
11807 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11808 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11809 These functions do the right thing with sizes > 2**32.
11810 (check_depth): Now ptrdiff_t, not int.
11811 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11812 Adjust to new way of storing sizes. Check for size overflow bugs
11814 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11815 slightly wrong anyway, as it missed one instance of
11816 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11817 (refill_memory_reserve): Omit needless cast to size_t.
11818 (mark_object_loop_halt): Mark as externally visible.
11820 * xselect.c: Integer signedness and overflow fixes.
11821 (Fx_register_dnd_atom, x_handle_dnd_message):
11822 Use ptrdiff_t, not size_t, since we prefer signed.
11823 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11824 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11825 x_dnd_atoms_size and x_dnd_atoms_length.
11827 * doprnt.c: Prefer signed to unsigned when either works.
11829 * doprnt.c (doprnt):
11831 * xdisp.c (vmessage):
11832 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11833 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11834 prefer signed arithmetic to avoid comparison confusion.
11835 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11836 but is a bit tricky.
11838 Assume freestanding C89 headers, string.h, stdlib.h.
11839 * data.c, doprnt.c, floatfns.c, print.c:
11840 Include float.h unconditionally.
11841 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11842 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11843 * regex.c: Likewise for stddef.h, string.h.
11844 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11845 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11846 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11847 (STDC_HEADERS): Remove obsolete defines.
11848 * sysdep.c: Include limits.h unconditionally.
11850 Assume support for memcmp, memcpy, memmove, memset.
11851 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11852 * regex.c (memcmp, memcpy):
11853 Remove; we assume C89 now.
11855 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11856 (__malloc_safe_bcopy): Remove; no longer needed.
11858 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11859 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11860 well either way, and we prefer signed to unsigned.
11862 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11864 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11865 closes the connection while we're reading (bug#9182).
11867 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11869 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11870 are specified (Bug#9168).
11872 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11874 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11875 Found by GCC static checking and --with-wide-int on a 32-bit host.
11877 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11879 * xdisp.c (compute_display_string_pos): Fix logic of caching
11880 previous display string position. Initialize cached_prev_pos to
11881 -1. Fixes slow-down at the beginning of a buffer.
11883 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11885 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11886 for attrs[LFACE_FONTSET_INDEX].
11888 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11890 * xml.c (parse_region): Remove unused local
11891 that was recently introduced.
11893 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11895 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11896 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11898 * xdisp.c (move_it_in_display_line_to): Record the best matching
11899 position for TO_CHARPOS while scanning the line, and restore it on
11900 exit if none of the characters scanned was an exact match.
11901 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11902 when exact match is impossible due to invisible text, and the
11903 lines are truncated.
11905 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11907 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11910 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11912 Fix a significant slow-down of cursor motion with C-n, C-p,
11913 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11914 auto-repeat under bidi redisplay in fontified buffers.
11915 * xdisp.c (compute_stop_pos_backwards): New function.
11916 (next_element_from_buffer): Call compute_stop_pos_backwards to
11917 find a suitable prev_stop when we find ourselves before
11919 (reseat): Don't look for prev_stop, as that could mean a very long
11921 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11922 <cached_disp_overlay_modiff>: Cache for last found display string
11924 (compute_display_string_pos): Return the cached position if asked
11925 about the same buffer in the same area of character positions, and
11926 the buffer wasn't changed since the time the display string
11927 position was cached.
11929 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11931 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11932 is an integer, which is important for empty lines. (Bug#9149)
11934 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11936 * frame.c (Fmodify_frame_parameters): In tty case, update the
11937 default face if necessary (Bug#4238).
11939 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11941 * editfns.c (Fstring_to_char): No need to explain what a character
11942 is in the docstring (Bug#6576).
11944 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11946 * xml.c (parse_region): Make sure we always return a tree.
11948 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11950 * xml.c (parse_region): If a document contains only comments,
11953 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11955 * xml.c (make_dom): Return comments, too.
11957 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11960 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11961 and the surrounding thread.
11962 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11963 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11964 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11966 * s/openbsd.h (BROKEN_SIGIO): Define.
11967 * unexelf.c (unexec) [__OpenBSD__]:
11968 Don't update the .mdebug section of the Alpha COFF symbol table.
11970 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11972 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11975 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11977 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11978 This fixes some race conditions on the permissions of any newly
11981 * alloc.c (valid_pointer_p): Use pipe, not open.
11982 This fixes some permissions issues when debugging.
11984 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11985 If fchown fails to set both uid and gid, try to set just gid,
11986 as that is sometimes allowed. Adjust the file's mode to eliminate
11987 setuid or setgid bits that are inappropriate if fchown fails.
11989 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11991 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11992 to compare Lisp_Objects.
11993 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11994 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11995 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11997 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11999 * lread.c (read_integer): Unread even EOF character.
12000 (read1): Likewise. Properly record start position of symbol.
12002 * lread.c (read1): Read `#:' as empty uninterned symbol if no
12003 symbol character follows.
12005 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
12007 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
12008 This works around a problem with the previous change to Fcopy_file.
12009 Recent glibc declares fchown with __attribute__((warn_unused_result)),
12010 and without this change, GCC might complain about discarding
12011 fchown's return value.
12013 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
12015 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
12017 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
12019 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
12021 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
12023 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
12024 it's used from the C level.
12026 * process.c: Use the same condition for POLL_FOR_INPUT in both
12027 keyboard.c and process.c (bug#1858).
12029 2011-07-09 Lawrence Mitchell <wence@gmx.li>
12031 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
12032 (Fgnutls_boot): Use it.
12034 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
12036 * doc.c (Fsubstitute_command_keys): Revert last change.
12038 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
12040 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
12041 quotes the next character, and doesn't affect other longer
12042 sequences (bug#8935).
12044 * lread.c (syms_of_lread): Clarify that is isn't only
12045 `eval-buffer' and `eval-defun' that's affected by
12046 `lexical-binding' (bug#8460).
12048 2011-07-15 Eli Zaretskii <eliz@gnu.org>
12050 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
12051 bidi redisplay when a line includes both an image and is truncated.
12053 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
12055 Fix minor problems found by static checking.
12056 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
12057 (elsz): Now a signed constant, not a size_t var. We prefer signed
12058 types to unsigned, to avoid integer comparison confusion. Without
12059 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
12060 "cannot optimize loop, the loop counter may overflow", a symptom
12062 * indent.c (Fvertical_motion): Mark locals as initialized.
12063 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
12065 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
12067 * search.c (Fre_search_backward): Mention `case-fold-search' in
12068 all the re_search_* functions (bug#8138).
12070 * keyboard.c (Fopen_dribble_file): Document when the file is
12073 2011-07-14 Eli Zaretskii <eliz@gnu.org>
12075 * bidi.c (bidi_dump_cached_states): Fix format of displaying
12078 Support bidi reordering of display and overlay strings.
12079 * xdisp.c (compute_display_string_pos)
12080 (compute_display_string_end): Accept additional argument STRING.
12081 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
12082 (reseat_to_string): Initialize bidi_it->string.s and
12083 bidi_it->string.schars.
12084 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
12085 NULL (avoids a crash in bidi_paragraph_init).
12086 Initialize itb.string.lstring.
12087 (init_iterator): Call bidi_init_it only of a valid
12088 buffer position was specified. Initialize paragraph_embedding to
12090 (reseat_to_string): Initialize the bidi iterator.
12091 (display_string): If we need to ignore text properties of
12092 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
12093 original value of -1 will not work with bidi.)
12094 (compute_display_string_pos): First arg is now struct
12095 `text_pos *'; all callers changed. Support display properties on
12097 (compute_display_string_end): Support display properties on Lisp
12099 (init_iterator, reseat_1, reseat_to_string): Initialize the
12100 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
12101 when iterating on a string not from display properties).
12102 (compute_display_string_pos, compute_display_string_end):
12103 Fix calculation of the object to scan. Fixes an error when using
12105 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
12106 base_level_stop; instead, set base_level_stop to BEGV.
12107 Fixes crashes in vertical-motion.
12108 (next_element_from_buffer): Improve commentary for when
12109 the iterator is before prev_stop.
12110 (init_iterator): Initialize bidi_p from the default value of
12111 bidi-display-reordering, not from buffer-local value. Use the
12112 buffer-local value only if initializing for buffer iteration.
12113 (handle_invisible_prop): Support invisible properties on strings
12114 that are being bidi-reordered.
12115 (set_iterator_to_next): Support bidi reordering of C strings and
12117 (next_element_from_string): Support bidi reordering of Lisp
12119 (handle_stop_backwards): Support Lisp strings as well.
12120 (display_string): Support display of R2L glyph rows.
12121 Use IT_STRING_CHARPOS when displaying from a Lisp string.
12122 (init_iterator): Don't initialize it->bidi_p for strings
12124 (reseat_to_string): Initialize it->bidi_p for strings here.
12125 (next_element_from_string, next_element_from_c_string)
12126 (next_element_from_buffer): Add xassert's for correspondence
12127 between IT's object being iterated and it->bidi_it.string
12129 (face_before_or_after_it_pos): Support bidi iteration.
12130 (next_element_from_c_string): Handle the case of the first string
12131 character that is not the first one in the visual order.
12132 (get_visually_first_element): New function, refactored from common

12585 * alloc.c (mark_buffer):
12586 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
12587 (clone_per_buffer_values): Don't assume that
12588 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
12589 This isn't true in general, and it's particularly not true
12590 if Emacs is configured with --with-wide-int.
12591 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
12592 New macros, used in the buffer.c change.

12628 Random fixes. E.g., (random) never returned negative values.
12629 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
12630 subseconds part to the entropy, as that's a bit more random.
12631 Prefer signed to unsigned, since the signedness doesn't matter and
12632 in general we prefer signed. When given a limit, use a
12633 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12634 latter isn't right if USE_2_TAGS_FOR_INTS.
12635 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12636 not 0..VALMASK. Don't discard "excess" bits that random () returns.
12638 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
12640 * textprop.c (text_property_stickiness):
12641 Obey Vtext_property_default_nonsticky.

12648 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
12649 This is more efficient than Ffile_directory_p and avoids a minor race.
12651 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
12653 * buffer.c (Foverlay_put): Say what the return value is
12656 * fileio.c (barf_or_query_if_file_exists): Check first if the file
12657 is a directory before asking whether to use the file name
12659 (barf_or_query_if_file_exists): Make the "File is a directory"
12660 error be more correct.
12662 * fns.c (Frequire): Remove the mention of the .gz files, since
12663 that's installation-specific, but keep the mention of
12664 `get-load-suffixes'.

12668 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

12676 Qgnutls_bootprop_verify_error (which is no longer used).
12678 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
12679 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
12680 Also (re)move comments that are misplaced or no longer relevant.
12682 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12684 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

12743 (syms_of_keymap): Defsubr make-composed-keymap.
12744 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

12781 * eval.c (struct backtrace): Simplify and port the data structure.
12782 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12783 signed bit field, as this assumption is not portable and it makes
12784 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12785 "char debug_on_exit : 1" as this is not portable either; instead,
12786 use the portable "unsigned int debug_on_exit : 1". Remove unused
12787 member evalargs. Remove obsolete comments about cc bombing out.
12789 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

13011 * dispnew.c (window_to_frame_vpos):
13012 * xfns.c (unwind_create_frame):
13013 * xterm.c (x_check_font): Remove unused local.
13014 * scroll.c (CHECK_BOUNDS):
13015 * xfaces.c (cache_fache): Rename local to avoid shadowing.
13016 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
13017 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
13018 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
13019 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
13021 (debug_method_add): Use va_list and vsprintf rather than relying
13022 on undefined behavior with wrong number of arguments.
13023 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
13024 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
13025 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
13026 since we're not interested in debugging glyphs with old libraries.
13027 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
13028 GCC 4.6.0's static checking.
13030 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13032 Integer overflow and signedness fixes (Bug#8873).
13033 A few related buffer overrun fixes, too.

13037 * dispextern.h (struct face.stipple):
13038 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)

13041 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
13042 (x_create_bitmap_from_xpm_data):
13043 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
13044 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
13046 * xfaces.c (load_pixmap):
13047 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
13048 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
13049 (.bitmaps_last, struct x_output.icon_bitmap):
13050 Use ptrdiff_t, not int, for bitmap indexes.
13051 (x_allocate_bitmap_record): Check for size overflow.
13052 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
13054 Use ptrdiff_t, not int, for overlay counts.
13055 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
13056 * editfns.c (overlays_around, get_pos_property):
13057 * textprop.c (get_char_property_and_overlay):
13058 * xdisp.c (next_overlay_change, note_mouse_highlight):
13059 * xfaces.c (face_at_buffer_position):
13060 * buffer.c (OVERLAY_COUNT_MAX): New macro.
13061 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
13062 (Fnext_overlay_change, Fprevious_overlay_change)
13063 (mouse_face_overlay_overlaps, Foverlays_in):
13064 Use ptrdiff_t, not int, for sizes.
13065 (overlays_at, overlays_in): Check for size-calculation overflow.
13067 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
13069 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
13070 (x_session_initialize): Do not assume string length fits in int.
13072 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
13073 This is unlikely, but can occur if DPI is outlandish.
13075 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
13076 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
13078 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
13079 * xrdb.c (magic_file_p, search_magic_path):
13080 Omit last arg SUFFIX; it was always 0. All callers changed.
13081 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
13083 * xfont.c (xfont_match): Avoid need for strlen.
13085 * xfns.c: Don't assume strlen fits in int.
13086 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
13088 * xdisp.c (message_log_check_duplicate): Return intmax_t,
13089 not unsigned long, as we prefer signed integers. All callers changed.
13090 Detect integer overflow in repeat count.
13091 (message_dolog): Don't assume print length fits in 39 bytes.
13092 (display_mode_element): Don't assume strlen fits in int.
13094 * termcap.c: Don't assume sizes fit in int and never overflow.
13095 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
13096 (gobble_line): Check for size-calculation overflow.
13098 * minibuf.c (Fread_buffer):
13099 * lread.c (intern, intern_c_string):
13100 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
13101 Don't assume string length fits in int.
13103 * keyboard.c (parse_tool_bar_item):
13104 * gtkutil.c (style_changed_cb): Avoid need for strlen.
13106 * font.c: Don't assume string length fits in int.
13107 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
13108 Use ptrdiff_t, not int.
13109 (font_intern_prop): Don't assume string length fits in int.
13110 Don't assume integer property fits in fixnum.
13111 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
13113 * filelock.c: Fix some buffer overrun and integer overflow issues.
13114 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
13115 Reformulate so as not to need the command string.
13116 Invoke gzip -cd rather than gunzip, as it's more portable.
13117 (lock_info_type, lock_file_1, lock_file):
13118 Don't assume pid_t and time_t fit in unsigned long.
13119 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
13120 (current_lock_owner): Prefer signed type for sizes.
13121 Use memcpy, not strncpy, where memcpy is what is really wanted.
13122 Don't assume (via atoi) that time_t and pid_t fit in int.
13123 Check for time_t and/or pid_t out of range, e.g., via a network share.
13124 Don't alloca where an auto var works fine.
13126 * fileio.c: Fix some integer overflow issues.
13127 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
13128 Don't assume string length fits in int.
13129 (directory_file_name): Don't assume string length fits in long.
13130 (make_temp_name): Don't assume pid fits in int, or that its print
13131 length is less than 20.
13133 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
13135 * coding.c (make_subsidiaries): Don't assume string length fits in int.
13137 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
13139 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
13140 We prefer signed integers, even for size calculations.
13142 * emacs.c: Don't assume string length fits in 'int'.
13143 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
13144 (main): Don't invoke strlen when not needed.
13146 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
13147 (XD_DEBUG_MESSAGE): Don't waste a byte.
13149 * callproc.c (getenv_internal_1, getenv_internal)
13150 (Fgetenv_internal):
13151 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
13153 * lread.c (invalid_syntax): Omit length argument.
13154 All uses changed. This doesn't fix a bug, but it simplifies the
13155 code away from its former Hollerith-constant appearance, and it's
13156 one less 'int' to worry about when looking at integer-overflow issues.
13157 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
13159 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
13160 This didn't break anything, but it didn't help either.
13161 It's confusing to put a bogus integer in a place where the actual
13162 value does not matter.
13163 (LIST_END_P): Remove unused macro and its bogus comment.
13164 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
13166 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
13167 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
13169 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
13170 We prefer signed types, and the value cannot exceed the EMACS_INT
13171 range anyway (because otherwise the length would not be representable).
13172 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
13173 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
13174 This avoids a GCC warning when WIDE_EMACS_INT.
13176 * indent.c (sane_tab_width): New function.
13177 (current_column, scan_for_column, Findent_to, position_indentation)
13178 (compute_motion): Use it. This is just for clarity.
13179 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
13181 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
13183 * lisp.h (lint_assume): New macro.
13184 * composite.c (composition_gstring_put_cache):
13185 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
13187 * editfns.c, insdel.c:
13188 Omit unnecessary forward decls, to simplify future changes.
13190 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
13192 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
13194 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
13195 Use much-faster test for byte-length change.
13196 Don't assume string byte-length fits in 'int'.
13197 Check that character arg fits in 'int'.
13198 (mapcar1): Declare byte as byte, for clarity.
13200 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
13202 * fns.c (concat): Catch string overflow earlier.
13203 Do not rely on integer wraparound.
13205 * dispextern.h (struct it.overlay_strings_charpos)
13206 (struct it.selective): Now EMACS_INT, not int.
13207 * xdisp.c (forward_to_next_line_start)
13208 (back_to_previous_visible_line_start)
13209 (reseat_at_next_visible_line_start, next_element_from_buffer):
13210 Don't arbitrarily truncate the value of 'selective' to int.
13212 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
13214 * composite.c: Don't truncate sizes to 'int'.
13215 (composition_gstring_p, composition_reseat_it)
13216 (composition_adjust_point): Use EMACS_INT, not int.
13217 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
13218 not EMACS_UINT, for indexes.
13220 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
13222 * buffer.c: Include <verify.h>.
13223 (struct sortvec.priority, struct sortstr.priority):
13224 Now EMACS_INT, not int.
13225 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
13226 (struct sortstr.size, record_overlay_string)
13227 (struct sortstrlist.size, struct sortlist.used):
13228 Don't truncate size to int.
13229 (record_overlay_string): Check for size-calculation overflow.
13230 (init_buffer_once): Check at compile-time, not run-time.
13232 2011-06-22 Jim Meyering <meyering@redhat.com>
13234 Don't leak an XBM-image-sized buffer
13235 * image.c (xbm_load): Free the image buffer after using it.
13237 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
13240 * composite.c (find_automatic_composition): Omit needless 'return 0;'
13241 that Sun C diagnosed.
13242 * fns.c (secure_hash): Fix pointer signedness issue.
13243 * intervals.c (static_offset_intervals): New function.
13244 (offset_intervals): Use it.
13246 2011-06-21 Leo Liu <sdl.web@gmail.com>
13249 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
13252 * fns.c (secure_hash): Rename from crypto_hash_function and change
13253 the first arg to accept symbols.
13254 (Fsecure_hash): New primitive.
13255 (syms_of_fns): New symbols.
13257 2011-06-20 Deniz Dogan <deniz@dogan.se>
13259 * process.c (Fset_process_buffer): Clarify return value in
13262 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
13264 * dispnew.c (add_window_display_history): Use BVAR.
13266 * xdisp.c (debug_method_add): Use BVAR.
13267 (check_window_end, dump_glyph_matrix, dump_glyph)
13268 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
13270 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
13273 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
13274 check till after the cache is created in init_frame_faces.
13276 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
13278 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
13280 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
13282 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
13283 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
13284 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
13286 Improve buffer-overflow checking (Bug#8873).
13287 * fileio.c (Finsert_file_contents):
13288 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
13289 Remove the old (too-loose) buffer overflow checks.
13290 They weren't needed, since make_gap checks for buffer overflow.
13291 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
13292 The old code merely checked for Emacs fixnum overflow, and relied
13293 on undefined (wraparound) behavior. The new code avoids undefined
13294 behavior, and also checks for ptrdiff_t and/or size_t overflow.
13296 * editfns.c (Finsert_char): Don't dump core with very negative counts.
13297 Tune. Don't use wider integers than needed. Don't use alloca.
13298 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
13300 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
13302 * insdel.c, lisp.h (buffer_overflow): New function.
13303 (insert_from_buffer_1, replace_range, replace_range_2):
13304 * insdel.c (make_gap_larger):
13305 * editfns.c (Finsert_char):
13306 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
13308 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
13310 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
13312 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
13314 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
13315 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
13317 * fileio.c: Don't assume EMACS_INT fits in off_t.
13318 (emacs_lseek): New static function.
13319 (Finsert_file_contents, Fwrite_region): Use it.
13320 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
13322 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
13324 * fns.c: Don't overflow int when computing a list length.
13325 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
13326 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
13327 truncation on 64-bit hosts. Check for QUIT every
13328 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
13329 faster and is responsive enough.
13330 (Flength): Report an error instead of overflowing an integer.
13331 (Fsafe_length): Return a float if the value is not representable
13332 as a fixnum. This shouldn't happen except in contrived situations.
13333 (Fnthcdr, Fsort): Don't assume list length fits in int.
13334 (Fcopy_sequence): Don't assume vector length fits in int.
13336 * alloc.c: Check that resized vectors' lengths fit in fixnums.
13337 (header_size, word_size): New constants.
13338 (allocate_vectorlike): Don't check size overflow here.
13339 (allocate_vector): Check it here instead, since this is the only
13340 caller of allocate_vectorlike that could cause overflow.
13341 Check that the new vector's length is representable as a fixnum.
13343 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
13344 The previous code was bogus. For example, next_almost_prime (32)
13345 returned 39, which is undesirable as it is a multiple of 3; and
13346 next_almost_prime (24) returned 25, which is a multiple of 5 so
13347 why was the code bothering to check for multiples of 7?
13349 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
13351 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
13353 Variadic C functions now count arguments with ptrdiff_t.
13354 This partly undoes my 2011-03-30 change, which replaced int with size_t.
13355 Back then I didn't know that the Emacs coding style prefers signed int.
13356 Also, in the meantime I found a few more instances where arguments
13357 were being counted with int, which may truncate counts on 64-bit
13358 machines, or EMACS_INT, which may be unnecessarily wide.
13359 * lisp.h (struct Lisp_Subr.function.aMANY)
13360 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
13361 Arg counts are now ptrdiff_t, not size_t.
13362 All variadic functions and their callers changed accordingly.
13363 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
13364 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
13365 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
13366 * callint.c (Fcall_interactively): Check arg count for overflow,
13367 to avoid potential buffer overrun. Use signed char, not 'int',
13368 for 'varies' array, so that we needn't bother to check its size
13369 calculation for overflow.
13370 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
13371 * eval.c (apply_lambda):
13372 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
13373 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
13374 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
13376 * callint.c (Fcall_interactively): Don't use index var as event count.
13378 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
13379 * mem-limits.h (SIZE): Remove; no longer used.
13381 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
13383 Remove unnecessary casts.
13384 * xterm.c (x_term_init):
13385 * xfns.c (x_set_border_pixel):
13386 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
13387 These aren't needed now that we assume ANSI C.
13389 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
13390 It's more likely to cause problems (due to unsigned overflow)
13393 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
13395 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
13397 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
13399 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
13401 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
13403 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
13405 GLYPH_CODE_FACE returns EMACS_INT, not int.
13406 * dispextern.h (merge_faces):
13407 * xfaces.c (merge_faces):
13408 * xdisp.c (get_next_display_element, next_element_from_display_vector):
13409 Don't assume EMACS_INT fits in int.
13411 * character.h (CHAR_VALID_P): Remove unused parameter.
13412 * fontset.c, lisp.h, xdisp.c: All uses changed.
13414 * editfns.c (Ftranslate_region_internal): Omit redundant test.
13416 * fns.c (concat): Minor tuning based on overflow analysis.
13417 This doesn't fix any bugs. Use int to hold character, instead
13418 of constantly refetching from Emacs object. Use XFASTINT, not
13419 XINT, for value known to be a character. Don't bother comparing
13420 a single byte to 0400, as it's always less.
13422 * floatfns.c (Fexpt):
13423 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
13425 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
13428 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
13430 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
13431 Without this fix, on a 64-bit host (aset S 0 4294967386) would
13432 incorrectly succeed when S was a string, because 4294967386 was
13433 truncated before it was used.
13435 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13436 Otherwise, an out-of-range integer could cause undefined behavior
13439 * composite.c: Use int, not EMACS_INT, for characters.
13440 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13441 EMACS_INT, for values that are known to be in character range.
13442 This doesn't fix any bugs but is the usual style inside Emacs and
13443 may generate better code on 32-bit machines.
13445 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13446 This is for reasons similar to the recent CHAR_STRING fix.
13447 * charset.c (Fencode_char): Check that character arg is actually
13448 a character. Pass an int to ENCODE_CHAR.
13449 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13450 wider than 'int', as a compile-time check to prevent future regressions
13453 * character.c (char_string): Remove unnecessary casts.
13455 Make sure a 64-bit char is never passed to CHAR_STRING.
13456 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13457 by silently ignoring the top 32 bits, allowing some values
13458 that were far too large to be valid characters.
13459 * character.h: Include <verify.h>.
13460 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13461 arguments are no wider than unsigned, as a compile-time check
13462 to prevent future regressions in this area.
13464 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
13465 (Fsubst_char_in_region):
13467 * xdisp.c (decode_mode_spec_coding):
13468 Adjust to CHAR_STRING's new requirement.
13469 * editfns.c (Finsert_char, Fsubst_char_in_region):
13470 * fns.c (concat): Check that character args are actually
13471 characters. Without this test, these functions did the wrong
13472 thing with wildly out-of-range values on 64-bit hosts.
13474 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13475 These casts should not be needed on 32-bit hosts, either.
13476 * keyboard.c (read_char):
13477 * lread.c (Fload): Remove casts to unsigned.
13479 * lisp.h (UNSIGNED_CMP): New macro.
13480 This fixes comparison bugs on 64-bit hosts.
13481 (ASCII_CHAR_P): Use it.
13482 * casefiddle.c (casify_object):
13483 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
13484 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
13485 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
13486 * dispextern.h (FACE_FROM_ID):
13487 * keyboard.c (read_char): Use UNSIGNED_CMP.
13489 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
13490 not to EMACS_INT, to avoid GCC warning.
13492 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13494 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13495 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
13496 isn't needed on 32-bit machines.
13498 * buffer.c (Fgenerate_new_buffer_name):
13499 Use EMACS_INT for count, not int.
13500 (advance_to_char_boundary): Return EMACS_INT, not int.
13502 * data.c (Qcompiled_function): Now static.
13504 * window.c (window_body_lines): Now static.
13506 * image.c (gif_load): Rename local to avoid shadowing.
13508 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
13509 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
13510 * alloc.c (make_save_value): Integer argument is now of type
13511 ptrdiff_t, not int.
13512 (mark_object): Use ptrdiff_t, not int.
13513 * lisp.h (pD): New macro.
13514 * print.c (print_object): Use it.
13516 * alloc.c: Use EMACS_INT, not int, to count objects.
13517 (total_conses, total_markers, total_symbols, total_vector_size)
13518 (total_free_conses, total_free_markers, total_free_symbols)
13519 (total_free_floats, total_floats, total_free_intervals)
13520 (total_intervals, total_strings, total_free_strings):
13521 Now EMACS_INT, not int. All uses changed.
13522 (Fgarbage_collect): Compute overall total using a double, so that
13523 integer overflow is less likely to be a problem. Check for overflow
13524 when converting back to an integer.
13525 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
13526 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
13527 These were 'int' variables that could overflow on 64-bit hosts;
13528 they were never used, so remove them instead of repairing them.
13529 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
13530 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
13531 Previously, this ceilinged at INT_MAX, but that doesn't work on
13533 (allocate_pseudovector): Don't use EMACS_INT when int would do.
13535 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
13536 (allocate_vectorlike): Check for ptrdiff_t overflow.
13537 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13538 when a (possibly-narrower) signed value would do just as well.
13539 We prefer using signed arithmetic, to avoid comparison confusion.
13541 * alloc.c: Catch some string size overflows that we were missing.
13542 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
13543 for convenience in STRING_BYTES_MAX.
13544 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
13545 The definition here is exact; the one in lisp.h was approximate.
13546 (allocate_string_data): Check for string overflow. This catches
13547 some instances we weren't catching before. Also, it catches
13548 size_t overflow on (unusual) hosts where SIZE_MAX <= min
13549 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
13550 and ptrdiff_t and EMACS_INT are both 64 bits.
13552 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
13553 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
13554 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
13556 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
13558 * alloc.c (Fmake_string): Check for out-of-range init.
13560 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
13562 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
13564 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
13566 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
13567 xg_get_default_scrollbar_width.
13569 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.

13577 and height if HAVE_GTK3 (Bug#8505).
13578 (scroll_bar_width_for_theme): New variable.
13579 (update_theme_scrollbar_width): New function.
13580 (xg_get_default_scrollbar_width): Move code to
13581 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
13582 (xg_initialize): Call update_theme_scrollbar_width.
13584 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
13586 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

13590 * frame.c (make_frame): Call other_buffer_safely instead of
13593 * window.c (temp_output_buffer_show): Call display_buffer with
13594 second argument Vtemp_buffer_show_specifiers and reset latter
13595 immediately after the call.
13596 (Vtemp_buffer_show_specifiers): New variable.
13597 (auto_window_vscroll_p, next_screen_context_lines)
13598 (Vscroll_preserve_screen_position): Remove leading asterisks from

14143 were just reseat()'ed to a new position.
14145 * xdisp.c (set_cursor_from_row): Set start and stop points
14146 according to the row's direction when priming the loop that looks
14147 for the glyph on which to display cursor.

14149 (display_prop_intangible_p): Reimplement to call
14150 handle_display_spec instead of single_display_spec_intangible_p.

14161 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
14162 value of a `display' property is a "replacing spec".
14163 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
14164 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
14165 the display property, but just return a value indicating whether
14166 the display property will replace the characters it covers.
14167 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
14168 frame_window_p members of struct bidi_it.

14194 * gnutls.c: Use Emacs's memory allocators.
14195 Without this change, the gnutls library would invoke malloc etc.
14196 directly, which causes problems on non-SYNC_INPUT hosts, and which
14197 runs afoul of improving memory_full behavior. (Bug#8761)
14198 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
14199 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
14200 xfree instead of the default malloc, realloc, free.
14201 (Fgnutls_boot): No need to check for memory allocation failure,
14202 since xmalloc does that for us.

14231 need to be updated by these changes.
14232 * fns.c (make_hash_table, maybe_resize_hash_table):
14233 Check for integer overflow with large hash tables.
14234 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
14235 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
14236 (SXHASH_REDUCE): New macro.
14237 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
14238 Use it instead of discarding useful hash info with large hash values.
14239 (sxhash_float): New function.
14240 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
14241 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
14242 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
14243 Rewrite to use FIXNUM_BITS, as this simplifies things.
14244 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
14245 Adjust signatures to match updated version of code.
14246 (consing_since_gc): Now EMACS_INT, since a single hash table can
14247 use more than INT_MAX bytes.

14296 Make it possible to run ./temacs.
14298 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,

14314 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
14315 (CCL_CODE_MIN): New macro.
14317 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
14319 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
14321 * eval.c (Qdebug): Now static.
14322 * lisp.h (Qdebug): Remove decl. This reverts a part of the
14323 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
14324 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
14326 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14328 * image.c: Various fixes to ImageMagick code comments.
14329 (Fimagemagick_types): Doc fix.
14331 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
14333 Minor fixes prompted by GCC 4.6.0 warnings.
14335 * xselect.c (converted_selections, conversion_fail_tag): Now static.
14337 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
14338 (x_clipboard_manager_save_all): Move extern decl to ...
14339 * xterm.h: ... here, so that it can be checked for consistency.
14341 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14343 * xselect.c (x_clipboard_manager_save_frame)
14344 (x_clipboard_manager_save_all): New functions.
14345 (Fx_clipboard_manager_save): Lisp function deleted.
14347 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
14348 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
14350 * xterm.h: Update prototype.
14352 2011-05-28 William Xu <william.xwl@gmail.com>
14354 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
14355 exiting (Bug#8239).
14357 2011-05-28 Jim Meyering <meyering@redhat.com>
14359 Avoid a sign-extension bug in crypto_hash_function.
14360 * fns.c (to_uchar): Define.
14361 (crypto_hash_function): Use it to convert some newly-signed
14362 variables to unsigned, to avoid sign-extension bugs. For example,
14363 without this change, (md5 "truc") would evaluate to
14364 45723a2aff78ff4fff7fff1114760e62 rather than the expected
14365 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
14366 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
14368 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14370 Integer overflow fixes.
14372 * dbusbind.c: Serial number integer overflow fixes.
14373 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
14374 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
14375 to hold a serial number that is too large for a fixnum.
14376 (Fdbus_method_return_internal, Fdbus_method_error_internal):
14377 Check for serial numbers out of range. Decode any serial number
14378 that was so large that it became a float. (Bug#8722)
14380 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
14381 (Fdbus_call_method, Fdbus_call_method_asynchronously):
14382 Use XFASTINT rather than XUINT when numbers are nonnegative.
14383 (xd_append_arg, Fdbus_method_return_internal):
14384 (Fdbus_method_error_internal): Likewise. Also, for unsigned
14385 arguments, check that Lisp number is nonnegative, rather than
14386 silently wrapping negative numbers around. (Bug#8722)
14387 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
14390 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
14392 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
14394 ccl: Add integer overflow checks.
14395 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
14396 (IN_INT_RANGE): New macros.
14397 (ccl_driver): Use them to check for integer overflow when
14398 decoding a CCL program. Many of the new checks are whether XINT (x)
14399 fits in int; it doesn't always, on 64-bit hosts. The new version
14400 doesn't catch all possible integer overflows, but it's an
14401 improvement. (Bug#8719)
14403 * alloc.c (make_event_array): Use XINT, not XUINT.
14404 There's no need for unsigned here.
14406 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
14407 This follows up to the 2011-05-06 change that substituted uintptr_t
14408 for EMACS_INT. This case wasn't caught back then.
14410 Rework Fformat to avoid integer overflow issues.
14411 * editfns.c: Include <float.h> unconditionally, as it's everywhere
14412 now (part of C89). Include <verify.h>.
14413 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
14414 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
14415 (Fformat): Avoid the prepass trying to compute sizes; it was only
14416 approximate and thus did not catch overflow reliably. Instead, walk
14417 through the format just once, formatting and computing sizes as we go,
14418 checking for integer overflow at every step, and allocating a larger
14419 buffer as needed. Keep track separately whether the format is
14420 multibyte. Keep only the most-recently calculated precision, rather
14421 than them all. Record whether each argument has been converted to
14422 string. Use EMACS_INT, not int, for byte and char and arg counts.
14423 Support field widths and precisions larger than INT_MAX. Avoid
14424 sprintf's undefined behavior with conversion specifications such as %#d
14425 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
14426 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
14427 formatting out-of-range floating point numbers with int
14428 formats. (Bug#8668)
14430 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
14432 * data.c: Avoid integer truncation in expressions involving floats.
14433 * data.c: Include <intprops.h>.
14434 (arith_driver): When there's an integer overflow in an expression
14435 involving floating point, convert the integers to floating point
14436 so that the resulting value does not suffer from catastrophic
14437 integer truncation. For example, on a 64-bit host (* 4
14438 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14439 Do not rely on undefined behavior after integer overflow.
14441 merge count_size_as_multibyte, parse_str_to_multibyte
14442 * character.c, character.h (count_size_as_multibyte):
14443 Rename from parse_str_to_multibyte; all uses changed.
14444 Check for integer overflow.
14445 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14446 since it's now a duplicate of the other. This is more of
14447 a character than a buffer op, so better that it's in character.c.
14448 * fns.c, print.c: Adjust to above changes.
14450 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14452 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14454 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14456 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14457 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14458 (x_clipboard_manager_save): Now static.
14459 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14461 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14462 (crypto_hash_function): Now static.
14463 Fix pointer signedness problems. Avoid unnecessary initializations.
14465 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14467 * termhooks.h (Vselection_alist): Make it terminal-local.
14469 * terminal.c (create_terminal): Initialize it.
14471 * xselect.c: Support for clipboard managers.
14472 (Vselection_alist): Move to termhooks.h as terminal-local var.
14473 (LOCAL_SELECTION): New macro.
14474 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14475 (symbol_to_x_atom): Remove gratuitous arg.
14476 (x_handle_selection_request, lisp_data_to_selection_data)
14477 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14478 (x_own_selection, x_get_local_selection, x_convert_selection):
14479 New arg, specifying work frame. Use terminal-local Vselection_alist.
14480 (some_frame_on_display): Delete unused function.
14481 (Fx_own_selection_internal, Fx_get_selection_internal)
14482 (Fx_disown_selection_internal, Fx_selection_owner_p)
14483 (Fx_selection_exists_p): New optional frame arg.
14484 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14485 (x_handle_selection_clear): Don't treat other terminals with the
14486 same keyboard specially. Use the terminal-local Vselection_alist.
14487 (x_clear_frame_selections): Use Frun_hook_with_args.
14489 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14491 * xterm.h: Add support for those atoms.
14493 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14495 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14496 (converted_selections, conversion_fail_tag): New global variables.
14497 (x_selection_request_lisp_error): Free the above.
14498 (x_get_local_selection): Remove unnecessary code.
14499 (x_reply_selection_request): Args changed; handle arbitrary array
14500 of converted selections stored in converted_selections.
14501 Separate the XChangeProperty and SelectionNotify steps.
14502 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14503 (x_convert_selection): New function.
14504 (x_handle_selection_event): Simplify.
14505 (x_get_foreign_selection): Don't ignore incoming requests while
14506 waiting for an answer; this will fail when we implement
14507 SAVE_TARGETS, and seems unnecessary anyway.
14508 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14509 (Vx_sent_selection_functions): Doc fix.
14511 2011-05-26 Leo Liu <sdl.web@gmail.com>
14513 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14515 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14517 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14519 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14520 for fringe update if it has periodic bitmap.
14521 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14522 and fringe_bitmap_periodic_p.
14524 * fringe.c (get_fringe_bitmap_data): New function.
14525 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14526 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14527 row. Mark glyph row for fringe update if periodicity changed.
14529 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14530 for fringe update unless it has periodic bitmap.
14532 2011-05-25 Kenichi Handa <handa@m17n.org>
14534 * xdisp.c (get_next_display_element): Set correct it->face_id for
14535 a static composition.
14537 2011-05-24 Leo Liu <sdl.web@gmail.com>
14540 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
14542 * fns.c (crypto_hash_function, Fsha1): New function.
14543 (Fmd5): Use crypto_hash_function.
14544 (syms_of_fns): Add Ssha1.
14546 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14548 * gnutls.c: Remove unused macros.
14549 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14550 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14551 Remove macros that are defined and never used.
14552 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14554 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14556 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14557 (Fx_get_selection_internal): Minor cleanup.
14558 (Fx_own_selection_internal): Rename arguments for consistency with
14561 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14563 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
14565 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14567 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
14569 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14571 * dispnew.c (scrolling_window): Don't exclude the case that the
14572 last enabled row in the desired matrix touches the bottom boundary.
14574 2011-05-21 Glenn Morris <rgm@gnu.org>
14576 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
14577 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
14578 and add some more files.
14580 2011-05-20 Eli Zaretskii <eliz@gnu.org>
14582 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
14583 report_file_error introduced by the change from 2011-05-07.
14585 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14587 * systime.h (Time): Define only if emacs is defined.
14588 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14589 where the include path doesn't have X11/X.h by default. See
14590 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14592 2011-05-20 Kenichi Handa <handa@m17n.org>
14594 * composite.c (find_automatic_composition): Fix previous change.
14596 2011-05-20 Glenn Morris <rgm@gnu.org>
14598 * lisp.mk: New file, split from Makefile.in.
14599 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14600 (shortlisp): Remove.
14601 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14603 2011-05-19 Glenn Morris <rgm@gnu.org>
14605 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14606 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14607 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14608 (lisp): Set the order to that of loadup.el.
14609 (shortlisp): Make it a copy of $lisp.
14610 (SOME_MACHINE_LISP): Remove.
14611 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14612 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14614 2011-05-18 Kenichi Handa <handa@m17n.org>
14616 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14617 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14618 (find_automatic_composition): Mostly rewrite for efficiency.
14620 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14622 * makefile.w32-in: Update dependencies.
14624 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14626 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14627 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14629 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14631 Fix some integer overflow issues, such as string length overflow.
14633 * insdel.c (count_size_as_multibyte): Check for string overflow.
14635 * character.c (lisp_string_width): Check for string overflow.
14636 Use EMACS_INT, not int, for string indexes and lengths; in
14637 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14638 the resulting string length overflows an EMACS_INT; instead,
14639 report a string overflow if no precision given. When checking for
14640 precision exhaustion, use a check that cannot possibly have
14641 integer overflow. (Bug#8675)
14642 * character.h (lisp_string_width): Adjust to new signature.
14644 * alloc.c (string_overflow): New function.
14645 (Fmake_string): Use it. This doesn't change behavior, but saves
14646 a few bytes and will simplify future changes.
14647 * character.c (string_escape_byte8): Likewise.
14648 * lisp.h (string_overflow): New decl.
14650 Fixups, following up to the user-interface timestamp change.
14651 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14652 for UI timestamps, instead of unsigned long.
14653 * msdos.c (mouse_get_pos): Likewise.
14654 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14655 * w32gui.h (Time): Define by including "systime.h" rather than by
14656 declaring it ourselves. (Bug#8664)
14658 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14659 * image.c (clear_image_cache): Likewise.
14661 * term.c (term_mouse_position): Don't assume time_t wraparound.
14663 Be more systematic about user-interface timestamps.
14664 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14665 and sometimes 'EMACS_UINT', to represent these timestamps.
14666 This change causes it to use 'Time' uniformly, as that's what X uses.
14667 This makes the code easier to follow, and makes it easier to catch
14668 integer overflow bugs such as Bug#8664.
14669 * frame.c (Fmouse_position, Fmouse_pixel_position):
14670 Use Time, not unsigned long, for user-interface timestamps.
14671 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14672 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14673 * keyboard.h (last_event_timestamp): Likewise.
14674 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14675 * menu.h (xmenu_show): Likewise.
14676 * term.c (term_mouse_position): Likewise.
14677 * termhooks.h (struct input_event.timestamp): Likewise.
14678 (struct terminal.mouse_position_hook): Likewise.
14679 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14680 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14681 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14682 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14683 what it was before.
14684 * menu.h, termhooks.h: Include "systime.h", for Time.
14686 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14687 Don't assume that the difference between two unsigned long values
14688 can fit into an integer. At this point, we know button_down_time
14689 <= event->timestamp, so the difference must be nonnegative, so
14690 there's no need to cast the result if double-click-time is
14691 nonnegative, as it should be; check that it's nonnegative, just in
14692 case. This bug is triggered when events are more than 2**31 ms
14693 apart (about 25 days). (Bug#8664)
14695 * xselect.c (last_event_timestamp): Remove duplicate decl.
14696 (x_own_selection): Remove needless cast to unsigned long.
14698 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14699 that always fit in int. Use a sentinel instead of a counter, to
14700 avoid a temp and to allay GCC's concerns about possible int overflow.
14701 * frame.h (struct frame): Use int for menu_bar_items_used
14702 instead of EMACS_INT, since it always fits in int.
14704 * menu.c (grow_menu_items): Check for int overflow.
14706 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14708 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14709 Before, the code was not consistent. These values cannot exceed
14710 2**31 - 1 so there's no need to make them unsigned.
14711 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14712 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14713 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14715 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14717 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14718 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14719 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14720 presumably because the widths might not match.
14722 * window.c (size_window): Avoid needless test at loop start.
14724 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14726 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14728 2011-05-12 Drew Adams <drew.adams@oracle.com>
14730 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14732 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14734 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14735 `width' to `bar_area_x' and `bar_area_width', respectively.
14736 (x_scroll_run): Take account of fringe background extension.
14738 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14739 Rename local vars `left' and `width' to `bar_area_x' and
14740 `bar_area_width', respectively.
14741 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14742 background extension.
14744 2011-05-10 Jim Meyering <meyering@redhat.com>
14746 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14748 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14750 * image.c (Finit_image_library): Return t for built-in image types,
14751 like pbm and xbm. (Bug#8640)
14753 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14755 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14757 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14759 * w32console.c (Fset_screen_color): Doc fix.
14760 (Fget_screen_color): New function.
14761 (syms_of_ntterm): Defsubr it.
14763 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14764 unlink the temporary file if Fcall_process didn't create it in the
14766 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14767 child process will be redirected to a file specified with `:file'.
14768 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14769 cue to call_process_cleanup not to close that handle.
14771 2011-05-07 Ben Key <bkey76@gmail.com>
14773 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14774 one of two shell specific rules, either bootstrap-temacs-CMD or
14775 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14776 to the previous implementation of the bootstrap-temacs rule.
14777 The bootstrap-temacs-CMD rule is similar to the previous
14778 implementation of the bootstrap-temacs rule except that it
14779 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14782 These changes, along with some changes to nt/configure.bat,
14783 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14784 earlier fix to add support for --cflags and --ldflags options
14785 that include quotes so that it works whether make uses cmd or
14788 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14790 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14791 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14793 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14794 a string. Handle both cases.
14795 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14796 (Fdbus_register_method): Use Qinvalid_function.
14798 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14800 * makefile.w32-in: Update dependencies.
14801 (LISP_H): Add inttypes.h and stdin.h.
14802 (PROCESS_H): Add unistd.h.
14804 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14806 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14807 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14809 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14811 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14813 * term.c (vfatal): Remove stray call to va_end.
14814 It's not needed and the C Standard doesn't allow it here anyway.
14816 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14817 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14819 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14822 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14824 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14826 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14828 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14830 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14832 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14833 * charset.c (Fdefine_charset_internal): Don't initialize
14834 charset.code_space[15]. The value was garbage, on hosts with
14835 32-bit int (Bug#8600).
14837 * lread.c (read_integer): Be more consistent with string-to-number.
14838 Use string_to_number to do the actual conversion; this avoids
14839 rounding errors and fixes some other screwups. Without this fix,
14840 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14841 (digit_to_number): Move earlier, for benefit of read_integer.
14842 Return -1 if the digit is out of range for the base, -2 if it is
14843 not a digit in any supported base. (Bug#8602)
14845 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14847 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14848 to match comment at start of function. This also removes a
14849 GCC warning about overflow in a 32+64-bit port.
14851 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14853 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14854 Reported by Stefan Monnier in
14855 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14856 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14857 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14859 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14860 (EMACS_UINTPTR): Likewise, with uintptr_t.
14862 * lisp.h: Prefer 64-bit EMACS_INT if available.
14863 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14864 on 32-bit hosts that have 64-bit int, so that they can access
14866 However, temporarily disable this change unless the temporary
14867 symbol WIDE_EMACS_INT is defined.
14869 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14871 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14872 This removes an assumption that EMACS_INT and long are the same
14873 width as pointers. The assumption is true for Emacs porting targets
14874 now, but we want to make other targets possible.
14875 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14876 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14877 In the rest of the code, change types of integers that hold casted
14878 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14879 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14880 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14881 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14882 No need to cast type when ORing.
14883 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14884 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14885 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14886 assume EMACS_INT is the same width as char *.
14887 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14888 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14889 Remove no-longer-needed casts.
14890 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14891 (xg_tool_bar_help_callback, xg_make_tool_item):
14892 Use EMACS_INTPTR to hold an integer
14893 that will be cast to void *; this can avoid a GCC warning
14894 if EMACS_INT is not the same width as void *.
14895 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14896 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14897 (current_message_1, set_message_1):
14898 Use a local to convert to proper width without a cast.
14899 * xmenu.c (dialog_selection_callback): Likewise.
14901 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14902 Also, don't assume VALBITS / RAND_BITS is less than 5,
14903 and don't rely on undefined behavior when shifting a 1 left into
14905 * lisp.h (get_random): Change signature to match.
14907 * lread.c (hash_string): Use size_t, not int, for hash computation.
14908 Normally we prefer signed values; but hashing is special, because
14909 it's better to use unsigned division on hash table sizes so that
14910 the remainder is nonnegative. Also, size_t is the natural width
14911 for hashing into memory. The previous code used 'int', which doesn't
14912 retain enough info to hash well into very large tables.
14913 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14915 * dbusbind.c: Don't possibly lose pointer info when converting.
14916 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14917 Use XPNTR rather than XHASH, so that the high-order bits of
14918 the pointer aren't lost when converting through void *.
14920 * eval.c (Fautoload): Don't double-shift a pointer.
14922 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14924 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14926 * gnutls.c (DEF_GNUTLS_FN):
14927 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14929 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14931 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14934 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14936 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14937 New version that can reserve upto 2GB of heap space.
14939 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14941 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14943 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14945 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14946 `gnutls_certificate_set_x509_key_file'.
14948 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
14950 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
14951 Update dependencies.
14953 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14955 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14956 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14957 Remove unused parameter `fildes'.
14958 * process.c (read_process_output, send_process): Don't pass it.
14960 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14962 Fix previous change: the library cache is defined in w32.c.
14963 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14964 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14966 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14968 Implement dynamic loading of GnuTLS on Windows.
14970 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14971 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14972 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14975 * gnutls.c (Qgnutls_dll): Define.
14976 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
14977 (gnutls_*): Declare function pointers.
14978 (init_gnutls_functions): New function to initialize function pointers.

14980 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
14981 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14982 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
14983 (emacs_gnutls_write, emacs_gnutls_read)
14984 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14985 (Fgnutls_available_p): New function.
14986 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
14987 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
14988 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.

14994 (w32_delayed_load): Move to w32.c.
14996 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
14998 * w32.c (QCloaded_from, Vlibrary_cache): Define.
14999 (w32_delayed_load): Move from image.c. When loading a library, record
15000 its filename in the :loaded-from property of the library id.
15001 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
15002 Initialize and staticpro them.
15003 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
15005 * process.c: Include lisp.h before w32.h, not after.
15006 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
15007 instead of gnutls_record_check_pending.
15009 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
15011 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
15013 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
15014 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
15017 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
15019 * xterm.c (x_set_frame_alpha): Do not set property on anything
15020 else than FRAME_X_OUTER_WINDOW (Bug#8608).
15022 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
15024 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
15026 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
15028 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

15042 * sysdep.c (wait_for_termination_1): Make static.
15043 (wait_for_termination, interruptible_wait_for_termination):
15044 Move after wait_for_termination_1.
15046 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
15048 * sysdep.c (interruptible_wait_for_termination): New function
15049 which is like wait_for_termination, but allows keyboard
15052 * callproc.c (Fcall_process): Add (:file "file") as an option for
15054 (Fcall_process_region): Ditto.
15056 2011-04-30 Eli Zaretskii <eliz@gnu.org>
15058 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
15059 rather than `XVECTOR (FOO)->size'.
15061 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
15062 inttypes.h, as a gnulib replacement is used if it not available in
15065 2011-04-21 Eli Zaretskii <eliz@gnu.org>
15067 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
15068 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
15069 of MOST_POSITIVE_FIXNUM. (Bug#8528)
15071 * coding.c (coding_alloc_by_realloc): Error out if destination
15072 will grow beyond MOST_POSITIVE_FIXNUM.
15073 (decode_coding_emacs_mule): Abort if there isn't enough place in
15074 charbuf for the composition carryover bytes. Reserve an extra

15082 aborting when %lld or %lll format is passed.
15083 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
15084 %llo or %llx format is passed. (Bug#8545)
15086 * window.c (window_scroll_line_based): Use a marker instead of
15087 simple variables to record original value of point. (Bug#7952)
15089 * doprnt.c (doprnt): Fix the case where a multibyte sequence
15090 produced by %s or %c overflows available buffer space. (Bug#8545)
15092 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
15094 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
15095 (SIZE_MAX): Move defn after all includes, as they might #define it.
15097 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15099 * w32.c (init_environment): Warn about defaulting HOME to C:\.

15119 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15121 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
15123 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
15125 * makefile.w32-in: Update dependencies.
15127 2011-04-27 Eli Zaretskii <eliz@gnu.org>
15129 Improve `doprnt' and its usage. (Bug#8545)
15130 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
15131 `format_end'. Remove support for %l as a conversion specifier.
15132 Don't use xrealloc. Improve diagnostics when the %l size modifier
15133 is used. Update the commentary.
15135 * eval.c (verror): Simplify calculation of size_t.
15137 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
15140 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
15142 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
15145 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15147 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
15148 This makes this file independent of the recent pseudovector change.
15150 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
15152 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
15154 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
15155 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
15156 Remove unused local.
15157 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
15159 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
15160 GCC 4.6.0 optimizes based on type-based alias analysis.
15161 For example, if b is of type struct buffer * and v of type struct
15162 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
15163 != &v->size, and therefore "v->size = 1; b->size = 2; return
15164 v->size;" must therefore return 1. This assumption is incorrect
15165 for Emacs, since it type-puns struct Lisp_Vector * with many other
15166 types. To fix this problem, this patch adds a new type struct
15167 vectorlike_header that documents the constraints on layout of vectors
15168 and pseudovectors, and helps optimizing compilers not get fooled
15169 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
15170 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
15171 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
15173 (XSETPVECTYPE): Rewrite in terms of new macro.
15174 (XSETPVECTYPESIZE): New macro, specifying both type and size.
15175 This is a bit clearer, and further avoids the possibility of
15176 undesirable aliasing.
15177 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
15178 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
15179 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
15180 since Lisp_Subr is a special case (no "next" field).
15181 (ASIZE): Now uses header.size rather than size.
15182 All previous uses of XVECTOR (foo)->size replaced to use this macro,
15183 to avoid the hassle of writing XVECTOR (foo)->header.size.
15184 (struct vectorlike_header): New type.
15185 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
15186 object, to help avoid aliasing.
15187 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
15188 (SUBRP): Likewise, since Lisp_Subr is a special case.
15189 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
15190 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
15191 (struct Lisp_Hash_Table): Combine first two members into a single
15192 struct vectorlike_header member. All uses of "size" and "next" members
15193 changed to be "header.size" and "header.next".
15194 * buffer.h (struct buffer): Likewise.
15195 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
15196 * frame.h (struct frame): Likewise.
15197 * process.h (struct Lisp_Process): Likewise.
15198 * termhooks.h (struct terminal): Likewise.
15199 * window.c (struct save_window_data, struct saved_window): Likewise.
15200 * window.h (struct window): Likewise.
15201 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
15202 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
15203 * buffer.c (init_buffer_once): Likewise.
15204 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
15206 * process.c (Fformat_network_address): Use local var for size,
15209 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
15211 Make the Lisp reader and string-to-float more consistent (Bug#8525)
15212 * data.c (atof): Remove decl; no longer used or needed.
15213 (digit_to_number): Move to lread.c.
15214 (Fstring_to_number): Use new string_to_number function, to be
15215 consistent with how the Lisp reader treats infinities and NaNs.
15216 Do not assume that floating-point numbers represent EMACS_INT
15217 without losing information; this is not true on most 64-bit hosts.
15218 Avoid double-rounding errors, by insisting on integers when
15219 parsing non-base-10 numbers, as the documentation specifies.
15220 * lisp.h (string_to_number): New decl, replacing ...
15221 (isfloat_string): Remove.
15222 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
15223 (read1): Do not accept +. and -. as integers; this
15224 appears to have been a coding error. Similarly, do not accept
15225 strings like +-1e0 as floating point numbers. Do not report
15226 overflow for integer overflows unless the base is not 10 which
15227 means we have no simple and reliable way to continue.
15228 Break out the floating-point parsing into a new
15229 function string_to_number, so that Fstring_to_number parses
15230 floating point numbers consistently with the Lisp reader.
15231 (digit_to_number): Move here from data.c. Make it static inline.
15232 (E_CHAR, EXP_INT): Remove, replacing with ...
15233 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
15234 (string_to_number): New function, replacing isfloat_string.
15235 This function checks for valid syntax and produces the resulting
15236 Lisp float number too. Rework it so that string-to-number
15237 no longer mishandles examples like "1.0e+". Use strtoumax,
15238 so that overflow for non-base-10 numbers is reported only when
15239 there's no portable and simple way to convert to floating point.
15241 * textprop.c (set_text_properties_1): Rewrite for clarity,
15242 and to avoid GCC warning about integer overflow.
15244 * intervals.h (struct interval): Use EMACS_INT for members
15245 where EMACS_UINT might cause problems. See
15246 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
15247 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
15248 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
15250 (offset_intervals): Tell GCC not to worry about length overflow
15251 when negating a negative length.
15253 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
15254 (overrun_check_free): Likewise.
15256 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
15257 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
15260 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15261 (gnutls_make_error): Rename local to avoid shadowing.
15262 (gnutls_emacs_global_deinit): ifdef out; not used.
15263 (Fgnutls_boot): Use const for pointer to readonly storage.
15264 Comment out unused local. Fix pointer signedness problems.
15266 * lread.c (openp): Don't stuff size_t into an 'int'.
15267 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
15268 about possible signed overflow.
15270 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15271 (GDK_KEY_g): Don't define if already defined.
15272 (xg_prepare_tooltip): Avoid pointer signedness problem.
15273 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
15275 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
15276 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
15278 * xfns.c (Fx_window_property): Simplify a bit,
15279 to make a bit faster and to avoid GCC 4.6.0 warning.
15280 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
15282 * fns.c (internal_equal): Don't assume size_t fits in int.
15284 * alloc.c (compact_small_strings): Tighten assertion a little.
15286 Replace pEd with more-general pI, and fix some printf arg casts.
15287 * lisp.h (pI): New macro, generalizing old pEd macro to other
15288 conversion specifiers. For example, use "...%"pI"d..." rather
15289 than "...%"pEd"...".
15290 (pEd): Remove. All uses replaced with similar uses of pI.
15291 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
15292 * alloc.c (check_pure_size): Don't overflow by converting size to int.
15293 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
15294 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
15295 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
15296 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
15297 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
15299 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
15300 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
15301 * print.c (safe_debug_print, print_object): Likewise.
15302 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
15304 Use pI instead of if-then-else-abort. Use %p to avoid casts,
15305 avoiding the 0 flag, which is not portable.
15306 * process.c (Fmake_network_process): Use pI to avoid cast.
15307 * region-cache.c (pp_cache): Likewise.
15308 * xdisp.c (decode_mode_spec): Likewise.
15309 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
15310 behavior on 64-bit hosts with printf arg.
15311 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
15312 (x_stop_queuing_selection_requests): Likewise.
15313 (x_get_window_property): Don't truncate byte count to an 'int'
15316 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
15317 here, since it parses constructs like leading '-' and spaces,
15318 which are not wanted; and it overflows with large numbers.
15319 Instead, simply match F[0-9]+, which is what is wanted anyway.
15321 * alloc.c: Remove unportable assumptions about struct layout.
15322 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
15323 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
15324 (allocate_vectorlike, make_pure_vector): Use the new macros,
15325 plus offsetof, to remove unportable assumptions about struct layout.
15326 These assumptions hold on all porting targets that I know of, but
15327 they are not guaranteed, they're easy to remove, and removing them
15328 makes further changes easier.
15330 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
15331 This doesn't fix a bug but makes the code clearer.
15332 (string_overrun_cookie): Now const. Use initializers that
15333 don't formally overflow signed char, to avoid warnings.
15334 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
15335 can cause Emacs to crash when string overrun checking is enabled.
15336 (allocate_buffer): Don't assume sizeof (struct buffer) is a
15337 multiple of sizeof (EMACS_INT); it need not be, if
15338 alignof(EMACS_INT) < sizeof (EMACS_INT).
15339 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
15341 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

15348 supposed to be handshaking. (Bug#8556)
15349 Reported by Paul Eggert <eggert@cs.ucla.edu>.
15351 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

15362 (check_string_free_list): Convert to standard C.
15364 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
15366 * w32.c (emacs_gnutls_push): Fix typo.
15368 2011-04-25 Eli Zaretskii <eliz@gnu.org>
15370 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
15371 "cast to pointer from integer of different size".
15373 Improve doprnt and its use in verror. (Bug#8545)
15374 * doprnt.c (doprnt): Document the set of format control sequences
15375 supported by the function. Use SAFE_ALLOCA instead of always
15378 * eval.c (verror): Don't limit the buffer size at size_max-1, that
15379 is one byte too soon. Don't use xrealloc; instead xfree and
15382 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
15384 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
15387 * gnutls.c: Renamed global_initialized to
15388 gnutls_global_initialized. Added internals for the
15389 :verify-hostname-error, :verify-error, and :verify-flags
15390 parameters of `gnutls-boot' and documented those parameters in the
15391 docstring. Start callback support.
15392 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
15393 unless a fatal error occurred. Call gnutls_alert_send_appropriate
15394 on error. Return error code.

15396 (emacs_gnutls_read): Likewise.
15397 (Fgnutls_boot): Return handshake error code.
15398 (emacs_gnutls_handle_error): New function.

15454 changes in globals.h immediately force recompilation.
15455 (TAGS): Depend on $(CURDIR)/m/intel386.h and
15456 $(CURDIR)/s/ms-w32.h.

15461 <char-direction-table>: Deleted.
15463 2011-04-23 Eli Zaretskii <eliz@gnu.org>
15465 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
15466 * doprnt.c: Include limits.h.
15467 (SIZE_MAX): New macro.
15468 (doprnt): Return a size_t value. 2nd arg is now size_t.
15469 Many local variables are now size_t instead of int or unsigned.
15470 Improve overflow protection. Support `l' modifier for integer
15471 conversions. Support %l conversion. Don't assume an EMACS_INT
15472 argument for integer conversions and for %c.
15474 * lisp.h (doprnt): Restore prototype.
15476 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
15477 $(SRC)/character.h.
15479 * Makefile.in (base_obj): Add back doprnt.o.
15481 * deps.mk (doprnt.o): Add back prerequisites.
15482 (callint.o): Depend on character.h.
15484 * eval.c (internal_lisp_condition_case): Include the handler
15485 representation in the error message.
15486 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
15487 when breaking from the loop.

15491 * callint.c (Fcall_interactively): When displaying error message
15492 about invalid control letter, pass the character's codepoint, not
15493 a pointer to its multibyte form. Improve display of the character
15494 in octal and display also its hex code.
15496 * character.c (char_string): Use %x to display the (unsigned)
15497 codepoint of an invalid character, to avoid displaying a bogus
15500 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15501 `error', not SYMBOL_NAME itself.
15503 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
15504 character arguments to `error'.
15506 * charset.c (check_iso_charset_parameter): Fix incorrect argument
15507 to `error' in error message about FINAL_CHAR argument. Make sure
15508 FINAL_CHAR is a character, and use %c when it is passed as
15509 argument to `error'.

15573 Define only if needed.
15575 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
15576 by pacifying GCC about it. Maybe it's time to retire it?
15577 * xfaces.c (USG, __TIMEVAL__): Likewise.
15579 * dispextern.h (struct redisplay_interface): Rename param
15580 to avoid shadowing.
15581 * termhooks.h (struct terminal): Likewise.
15582 * xterm.c (xembed_send_message): Likewise.
15584 * insdel.c (make_gap_smaller): Define only if
15585 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
15587 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
15590 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
15591 so that we aren't warned about unused symbols.
15593 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
15595 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
15597 * xfns.c (x_real_positions): Mark locals as initialized.
15599 * xmenu.c (xmenu_show): Don't use uninitialized vars.
15601 * xterm.c: Fix problems found by static analysis with other toolkits.
15602 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
15603 (x_dispatch_event): Declare static if USE_GTK, and
15604 define if USE_GTK || USE_X_TOOLKIT.
15605 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
15606 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
15607 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
15608 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
15610 * xmenu.c (menu_help_callback): Pointer type fixes.
15611 Use const pointers when pointing at readonly data. Avoid pointer

15625 only if HAVE_X_WINDOWS && !USE_X_TOOLKIT.
15627 * bitmaps: Change bitmaps from unsigned char back to the X11
15628 compatible char. Avoid the old compiler warnings about
15629 out-of-range initializers by using, for example, '\xab' rather
15632 * xgselect.c (xgselect_initialize): Check vs interface

16070 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
16072 alloc.c: Import and export fewer symbols, and remove unused items.
16073 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
16075 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
16076 it's not optimized away by whole-program optimization.
16077 (message_enable_multibyte, free_misc): Remove.
16078 (catchlist, handlerlist, mark_backtrace):
16079 Declare only if BYTE_MARK_STACK.
16080 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
16081 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
16082 (message_enable_multibyte): Remove decl.
16083 (free_misc, interval_free_list, float_block, float_block_index):
16084 (n_float_blocks, float_free_list, cons_block, cons_block_index):
16085 (cons_free_list, last_marked_index):
16087 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
16088 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
16089 (mark_backtrace): Define only if BYTE_MARK_STACK.
16090 * xdisp.c (message_enable_multibyte): Now static.
16092 Declare Lisp_Object Q* variables to be 'static' if not exported.
16093 This makes it easier for human readers (and static analyzers)
16094 to see whether these variables are used from other modules.
16095 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
16096 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
16097 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
16098 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
16099 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
16100 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
16101 * xmenu.c, xselect.c:
16102 Declare Q* vars static if they are not used in other modules.
16103 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
16104 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
16105 Remove decls of unexported vars.
16106 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
16108 * lisp.h (DEFINE_FUNC): Make sname 'static'.
16110 Make Emacs functions such as Fatom 'static' by default.
16111 This makes it easier for human readers (and static analyzers)
16112 to see whether these functions can be called from other modules.
16113 DEFUN now defines a static function. To make the function external
16114 so that it can be used in other C modules, use the new macro DEFUE.
16115 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
16116 (Finit_image_library):
16117 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
16118 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
16119 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
16120 Remove decls, since these functions are now static.
16121 (Funintern, Fget_internal_run_time): New decls, since these functions
16122 were already external.
16124 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
16125 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
16126 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
16127 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
16128 * keyboard.c, keymap.c, lread.c:
16129 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
16130 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
16131 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
16132 Mark functions with DEFUE instead of DEFUN,
16133 if they are used in other modules.
16134 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
16135 decls for now-static functions.
16136 * buffer.h (Fdelete_overlay): Remove decl.
16137 * callproc.c (Fgetenv_internal): Mark as internal.
16138 * composite.c (Fremove_list_of_text_properties): Remove decl.

16142 * doc.c (Fdocumntation_property): New forward static decl.
16143 * eval.c (Ffetch_bytecode): New forward static decl.
16144 (Funintern): Remove extern decl; now in .h file where it belongs.
16145 * fileio.c (Fmake_symbolic_link): New forward static decl.
16146 * image.c (Finit_image_library): New forward static decl.
16147 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
16148 * intervals.h (Fprevious_property_change):
16149 (Fremove_list_of_text_properties): Remove decls.
16150 * keyboard.c (Fthis_command_keys): Remove decl.
16151 (Fcommand_execute): New forward static decl.
16152 * keymap.c (Flookup_key): New forward static decl.
16153 (Fcopy_keymap): Now static.
16154 * keymap.h (Flookup_key): Remove decl.
16155 * process.c (Fget_process): New forward static decl.
16156 (Fprocess_datagram_address): Mark as internal.

16169 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
16172 2011-04-13 Eli Zaretskii <eliz@gnu.org>
16174 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
16175 when at ZV. (Bug#8487)
16177 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
16179 * charset.c (Fclear_charset_maps): Use xfree instead of free.
16181 * keyboard.c (parse_tool_bar_item): Likewise.
16182 * sound.c (sound_cleanup, alsa_close): Likewise.
16183 * termcap.c (tgetent): Likewise.
16184 * xfns.c (x_default_font_parameter): Likewise.
16185 * xsettings.c (read_and_apply_settings): Likewise.
16187 * alloc.c (overrun_check_malloc, overrun_check_realloc)
16188 (overrun_check_free): Protoize.
16190 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
16192 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
16193 since callers should never pass a negative size.
16194 Change the signature to match that of plain 'read' and 'write'; see
16195 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
16196 * lisp.h: Update prototypes of emacs_write and emacs_read.
16198 2011-04-11 Eli Zaretskii <eliz@gnu.org>
16200 * xdisp.c (redisplay_window): Don't try to determine the character
16201 position of the scroll margin if the window start point w->startp
16202 is outside the buffer's accessible region. (Bug#8468)
16204 2011-04-10 Eli Zaretskii <eliz@gnu.org>
16206 Fix write-region and its subroutines for buffers > 2GB.
16207 * fileio.c (a_write, e_write): Modify declaration of arguments and
16208 local variables to support buffers larger than 2GB.
16209 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
16211 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
16212 argument, local variables, and return value.
16214 * lisp.h: Update prototypes of emacs_write and emacs_read.
16216 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
16218 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
16220 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
16222 Fix more problems found by GCC 4.6.0's static checks.
16224 * xdisp.c (vmessage): Use a better test for character truncation.
16226 * charset.c (load_charset_map): <, not <=, for optimization,
16227 and to avoid potential problems with integer overflow.
16228 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
16229 * casetab.c (set_identity, shuffle): Likewise.
16230 * editfns.c (Fformat): Likewise.
16231 * syntax.c (skip_chars): Likewise.
16233 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
16234 This also lets GCC 4.6.0 generate slightly better loop code.
16236 * callint.c (Fcall_interactively): <, not <=, for optimization.
16237 (Fcall_interactively): Count the number of arguments produced,
16238 not the number of arguments given. This is simpler and lets GCC
16239 4.6.0 generate slightly better code.
16241 * ftfont.c: Distingish more carefully between FcChar8 and char.
16242 The previous code passed unsigned char * to a functions like
16243 strlen and xstrcasecmp that expect char *, which does not
16244 conform to the C standard.
16245 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
16246 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
16247 char * when the C standard requires it.
16249 * keyboard.c (read_char): Remove unused var.
16251 * eval.c: Port to Windows vsnprintf (Bug#8435).
16252 Include <limits.h>.
16253 (SIZE_MAX): Define if the headers do not.
16254 (verror): Do not give up if vsnprintf returns a negative count.
16255 Instead, grow the buffer. This ports to Windows vsnprintf, which
16256 does not conform to C99. Problem reported by Eli Zaretskii.
16257 Also, simplify the allocation scheme, by avoiding the need for
16258 calling realloc, and removing the ALLOCATED variable.
16260 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
16262 Remove invocations of doprnt, as Emacs now uses vsnprintf.
16263 But keep the doprint source code for now, as we might revamp it
16264 and use it again (Bug#8435).
16265 * lisp.h (doprnt): Remove.
16266 * Makefile.in (base_obj): Remove doprnt.o.
16267 * deps.mk (doprnt.o): Remove.
16269 error: Print 32- and 64-bit integers portably (Bug#8435).
16270 Without this change, on typical 64-bit hosts error ("...%d...", N)
16271 was used to print both 32- and 64-bit integers N, which relied on
16272 undefined behavior.
16273 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
16274 * lisp.h (error, verror): Mark as printf-like functions.
16275 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
16276 Report overflow in size calculations when allocating printf buffer.
16277 Do not truncate output string at its first null byte.
16278 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
16279 Truncate the output at a character boundary, since vsnprintf does not
16281 * charset.c (check_iso_charset_parameter): Convert internal
16282 character to string before calling 'error', since %c now has the
16284 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
16285 overflow when computing char to be passed to 'error'. Do not
16286 pass Lisp_Object to 'error'; pass the integer instead.
16287 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
16288 formatted with plain %d.
16290 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
16292 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
16294 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
16296 * xterm.c (x_catch_errors): Remove duplicate declaration.
16298 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
16300 * xdisp.c, lisp.h (message_nolog): Remove; unused.
16302 2011-04-10 Jim Meyering <meyering@redhat.com>
16304 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
16305 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
16306 return ssize_t not "int", and use size_t as the buffer length.
16307 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
16308 * gnutls.h: Update declarations.
16309 * process.c (read_process_output): Use ssize_t, to match.
16310 (send_process): Likewise.
16312 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16314 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
16316 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16318 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
16319 Use unsigned char, to match FcChar8 type definition.
16321 * xterm.c (handle_one_xevent):
16322 * xmenu.c (create_and_show_popup_menu):
16323 * xselect.c (x_decline_selection_request)
16324 (x_reply_selection_request): Avoid type-punned deref of X events.
16326 2011-04-09 Eli Zaretskii <eliz@gnu.org>
16328 Fix some uses of `int' instead of EMACS_INT.
16329 * search.c (string_match_1, fast_string_match)
16330 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
16331 (scan_buffer, find_next_newline_no_quit)
16332 (find_before_next_newline, search_command, Freplace_match)
16333 (Fmatch_data): Make some `int' variables be EMACS_INT.
16335 * xdisp.c (display_count_lines): 3rd argument and return value now
16336 EMACS_INT. All callers changed.
16337 (pint2hrstr): Last argument is now EMACS_INT.
16339 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
16340 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
16341 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
16342 (decode_coding_utf_16, decode_coding_emacs_mule)
16343 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
16344 (decode_coding_ccl, decode_coding_charset)
16345 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
16346 (decode_coding_iso_2022, decode_coding_emacs_mule)
16347 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
16348 <char_offset, last_offset>: Declare EMACS_INT.
16349 (encode_coding_utf_8, encode_coding_utf_16)
16350 (encode_coding_emacs_mule, encode_invocation_designation)
16351 (encode_designation_at_bol, encode_coding_iso_2022)
16352 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
16353 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
16355 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
16356 (encode_invocation_designation): Last argument P_NCHARS is now
16358 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
16359 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
16361 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
16364 * ccl.c (Fccl_execute_on_string): Declare some variables
16367 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
16369 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
16371 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
16373 * process.c (Fformat_network_address): Doc fix.
16375 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
16377 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
16379 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
16381 * keyboard.c (read_char): Call Lisp function help-form-show,
16382 instead of using internal_with_output_to_temp_buffer.
16383 (Qhelp_form_show): New var.
16384 (syms_of_keyboard): Use DEFSYM macro.
16386 * print.c (internal_with_output_to_temp_buffer): Function deleted.
16388 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
16390 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
16392 * process.c (Flist_processes): Remove to Lisp.
16393 (list_processes_1): Delete.
16395 2011-04-06 Eli Zaretskii <eliz@gnu.org>
16397 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
16399 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
16401 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
16403 Fix more problems found by GCC 4.6.0's static checks.
16405 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
16407 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
16409 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
16411 * xdisp.c (vmessage): Mark as a printf-like function.
16413 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
16415 * sound.c (sound_warning): Don't crash if arg contains a printf format.
16417 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
16418 printf-like functions.
16419 (tiff_load): Add casts to remove these marks before passing them
16420 to system-supplied API.
16422 * eval.c (Fsignal): Remove excess argument to 'fatal'.
16424 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
16425 This avoids several warnings with gcc -Wstrict-overflow.
16426 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
16427 directly, rather than having caller test rule sign. This avoids
16428 some unnecessary tests.
16429 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
16430 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
16431 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
16433 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16434 (xfont_open): Avoid unnecessary tests.
16436 * composite.c (composition_gstring_put_cache): Use unsigned integer.
16438 * composite.h, composite.c (composition_gstring_put_cache):
16439 Use EMACS_INT, not int, for length.
16441 * composite.h (COMPOSITION_DECODE_REFS): New macro,
16442 breaking out part of COMPOSITION_DECODE_RULE.
16443 (COMPOSITION_DECODE_RULE): Use it.
16444 * composite.c (get_composition_id): Remove unused local vars,
16445 by using the new macro.
16447 * textprop.c (set_text_properties_1): Change while to do-while,
16448 since the condition is always true at first.
16450 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16451 (interval_deletion_adjustment): Return unsigned value.
16454 * process.c (list_processes_1, create_pty, read_process_output):
16455 (exec_sentinel): Remove vars that were set but not used.
16456 (create_pty): Remove unnecessary "volatile"s.
16457 (Fnetwork_interface_info): Avoid possibility of int overflow.
16458 (read_process_output): Do adaptive read buffering even if carryover.
16459 (read_process_output): Simplify nbytes computation if buffered.
16461 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
16463 * syntax.c (scan_words): Remove var that was set but not used.
16464 (update_syntax_table): Use unsigned instead of int.
16466 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
16467 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
16468 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
16470 * print.c (print_error_message): Avoid int overflow.
16472 * font.c (font_list_entities): Redo for clarity,
16473 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
16475 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
16476 (font_score): Avoid potential overflow in diff calculation.
16478 * fns.c (substring_both): Remove var that is set but not used.
16479 (sxhash): Redo loop for clarity and to avoid wraparound warning.
16481 * eval.c (funcall_lambda): Rename local to avoid shadowing.
16483 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
16484 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
16485 can always succeed if overflow has undefined behavior.
16487 * search.c (boyer_moore, wordify): Remove vars set but not used.
16488 (wordify): Omit three unnecessary tests.
16490 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
16491 All callers changed. This avoids the need for an unused var.
16493 * casefiddle.c (casify_region): Remove var that is set but not used.
16495 * dired.c (file_name_completion): Remove var that is set but not used.
16497 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
16499 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16500 (Finsert_file_contents): Remove unnecessary code checking fd.
16502 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
16503 Check for integer overflow on size calculations.
16505 * buffer.c (Fprevious_overlay_change): Remove var that is set
16508 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16509 Remove vars that are set but not used.
16510 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16511 (timer_check_2): Mark vars as initialized.
16513 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16515 * image.c (lookup_image): Remove var that is set but not used.
16516 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16518 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16519 that are set but not used.
16521 * xfns.c (make_invisible_cursor): Don't return garbage
16522 if XCreateBitmapFromData fails (Bug#8410).
16524 * xselect.c (x_get_local_selection, x_handle_property_notify):
16525 Remove vars that are set but not used.
16527 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

16531 Remove var that is set but not used.
16532 (scroll_bar_windows_size): Now size_t, not int.
16533 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16534 Check for overflow.
16536 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16537 (map_tty_color) [!defined MSDOS]: Likewise.
16539 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16541 * coding.c: Remove vars that are set but not used.
16542 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
16543 All callers changed.

16549 that is set but not used.
16551 * print.c (print_object): Remove var that is set but not used.
16553 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16554 The gnulib version avoids calling malloc in the usual case,
16555 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16556 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16557 * filelock.c (current_lock_owner): Likewise.
16558 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16559 * sysdep.c: Include allocator.h, careadlinkat.h.
16560 (emacs_no_realloc_allocator): New static constant.
16561 (emacs_readlink): New function.
16562 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16563 ../lib/careadlinkat.h.
16565 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
16567 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

16589 do not dereference NULL upon failed strdup
16590 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16591 (ns_get_family): Likewise.
16593 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16595 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16597 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16599 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16602 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16604 Add lexical binding.
16606 * window.c (Ftemp_output_buffer_show): New fun.

16615 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16617 (syms_of_lread): Declare `lexical-binding'.
16619 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16621 * keyboard.c (eval_dyn): New fun.
16622 (menu_item_eval_property): Use it.
16624 * image.c (parse_image_spec): Use Ffunctionp.
16626 * fns.c (concat, mapcar1): Accept byte-code-functions.
16628 * eval.c (Fsetq): Handle lexical vars.
16629 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16630 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16631 (FletX, Flet): Obey lexical binding.
16632 (Fcommandp): Handle closures.
16633 (Feval): New `lexical' arg.
16634 (eval_sub): New function extracted from Feval. Use it almost
16635 everywhere where Feval was used. Look up vars in lexical env.
16637 (Ffunctionp): Move from subr.el.
16638 (Ffuncall): Handle closures.
16639 (apply_lambda): Remove `eval_flags'.
16640 (funcall_lambda): Handle closures and new byte-code-functions.
16641 (Fspecial_variable_p): New function.
16642 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16643 but without exporting it to Lisp.
16645 * doc.c (Fdocumentation, store_function_docstring):
16646 * data.c (Finteractive_form): Handle closures.
16648 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16651 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16653 (exec_byte_code): New function extracted from Fbyte_code to handle new
16654 calling convention for byte-code-functions. Add new byte-codes.
16656 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
16658 * alloc.c (Fmake_symbol): Init new `declared_special' field.
16660 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16662 * xdisp.c (redisplay_internal): Fix prototype.
16664 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16666 * xdisp.c (SCROLL_LIMIT): New macro.
16667 (try_scrolling): Use it when setting scroll_limit.
16668 Limit scrolling to 100 screen lines.
16669 (redisplay_window): Even when falling back on "recentering",
16670 position point in the window according to scroll-conservatively,
16671 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16673 (try_scrolling): When point is above the window, allow searching
16674 as far as scroll_max, or one screenful, to compute vertical
16675 distance from PT to the scroll margin position. This prevents
16676 try_scrolling from unnecessarily failing when
16677 scroll-conservatively is set to a value slightly larger than the
16678 window height. Clean up the case of PT below the margin at bottom
16679 of window: scroll_max can no longer be INT_MAX. When aggressive
16680 scrolling is in use, don't let point enter the opposite scroll
16681 margin as result of the scroll.
16682 (syms_of_xdisp) <scroll-conservatively>: Document the
16683 threshold of 100 lines for never-recentering scrolling.

16690 (message_log_check_duplicate): Remove parameters `prev_bol' and
16691 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16692 (redisplay_internal): Remove parameter `preserve_echo_area',
16693 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16695 * indent.c (Fvertical_motion):
16696 * window.c (window_scroll_pixel_based, Frecenter):
16697 Don't pass `need_y_p' to `move_it_by_lines'.
16699 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16701 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16702 steal a few bits to be more compact.
16703 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16704 Remove unneeded casts.
16706 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16708 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16710 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16711 binding" message (bug#7967).
16713 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16715 Fix more problems found by GCC 4.6.0's static checks.
16717 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16718 Remove unused local var.
16720 * editfns.c (Fmessage_box): Remove unused local var.
16722 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16723 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16724 Omit unused local vars.
16725 * window.c (shrink_windows): Omit unused local var.
16726 * menu.c (digest_single_submenu): Omit unused local var.
16727 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16728 Omit unused local var.
16730 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16731 Don't assume string length fits in int.
16732 (keyremap_step, read_key_sequence): Use size_t for sizes.

16736 instead of alloca (Bug#8344).
16738 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16739 (Fbacktrace_frame): Don't assume nframes fits in int.
16741 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

16748 * cm.c (calccost): Turn while-do into do-while, for clarity.
16750 * keyboard.c (syms_of_keyboard): Use the same style as later
16751 in this function when indexing through an array. This also
16752 works around GCC bug 48267.
16754 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16756 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16758 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16759 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16761 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16762 This avoids undefined behavior on integer overflow, and is a bit
16763 more convenient anyway since it is compared to a size_t variable.
16765 Variadic C functions now count arguments with size_t, not int.
16766 This avoids an unnecessary limitation on 64-bit machines, which
16767 caused (substring ...) to crash on large vectors (Bug#8344).

16777 * fns.c (concat): Likewise.
16778 * frame.c (x_set_frame_parameters): Likewise.
16779 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16780 0 if not found, not -1. All callers changed.
16782 * alloc.c (garbage_collect): Don't assume stack size fits in int.
16783 (stack_copy_size): Now size_t, not int.
16784 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
16786 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
16788 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
16789 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

16805 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
16806 don't set the hook to nil, but remove the offending function instead.
16807 (Qcommand_hook_internal): Remove, unused.
16808 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
16809 Vcommand_hook_internal.

16812 (funcall_nil, funcall_not): New functions.
16813 (run_hook_with_args): Call each function through a `funcall' argument.

16939 (w32_wnd_proc): Remove unused variable `isdead'.
16940 (unwind_create_frame): Use #if GLYPH_DEBUG, not #ifdef.
16941 (Fx_server_max_request_size): Remove unused variable `dpyinfo'.

16947 * w32term.c (x_draw_composite_glyph_string_foreground):
16948 Remove unused variable `width'.
16950 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
16952 * w32term.c (x_set_glyph_string_clipping):
16953 Don't pass uninitialized region to CombineRgn.
16955 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
16957 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.

16977 2011-03-23 Julien Danjou <julien@danjou.info>
16979 * term.c (Fsuspend_tty, Fresume_tty):
16980 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
16981 * window.c (temp_output_buffer_show):
16982 * insdel.c (signal_before_change):
16983 * frame.c (Fhandle_switch_frame):
16984 * fileio.c (Fdo_auto_save):

16987 * cmds.c (internal_self_insert):
16988 * callint.c (Fcall_interactively):
16989 * buffer.c (Fkill_all_local_variables):
16990 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
16992 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
16993 unconditionally since it does the check itself.
16995 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
16997 Fix more problems found by GCC 4.5.2's static checks.
16999 * coding.c (encode_coding_raw_text): Avoid unnecessary test
17000 the first time through the loop, since we know p0 < p1 then.
17001 This also avoids a gcc -Wstrict-overflow warning.
17003 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
17004 leading to a memory leak, possible in functions like
17005 load_charset_map_from_file that can allocate an unbounded number
17006 of objects (Bug#8318).
17008 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
17009 that could (at least in theory) be that large.
17011 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
17012 This is less likely to overflow, and avoids undefined behavior if
17013 overflow does occur. All callers changed. Use strtoul to scan
17014 for the unsigned long integer.
17015 (pint2hrstr): Simplify and tune code slightly.
17016 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
17018 * scroll.c (do_scrolling): Work around GCC bug 48228.
17019 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
17021 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
17022 This also avoids a warning with gcc -Wstrict-overflow.
17023 (validate_x_resource_name): Simplify count usage.
17024 This also avoids a warning with gcc -Wstrict-overflow.
17026 * fileio.c (Fcopy_file): Report error if fchown or fchmod
17029 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
17031 * process.c (Fmake_network_process): Use socklen_t, not int,
17032 where POSIX says socklen_t is required in portable programs.
17033 This fixes a porting bug on hosts like 64-bit HP-UX, where
17034 socklen_t is wider than int (Bug#8277).
17035 (Fmake_network_process, server_accept_connection):
17036 (wait_reading_process_output, read_process_output):
17039 * process.c: Rename or move locals to avoid shadowing.

17049 Make tparam.h and terminfo.c consistent.
17050 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
17051 Include tparam.h instead, since it declares them.
17052 * cm.h (PC): Remove extern decl; tparam.h now does this.
17053 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
17054 * terminfo.c: Include tparam.h, to check interfaces.
17055 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
17056 (tparam): Adjust signature to match interface in tparam.h;
17057 this removes some undefined behavior. Check that outstring and len
17058 are zero, which they always are with Emacs.
17059 * tparam.h (PC, BC, UP): New extern decls.
17061 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
17062 (xftfont_open): Rename locals to avoid shadowing.
17064 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
17065 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
17066 (OTF_TAG_SYM): Omit macro if not needed.

17068 (get_adstyle_property, ftfont_pattern_entity):
17069 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
17070 Rename locals to avoid shadowing.
17072 * xfont.c (xfont_list_family): Mark var as initialized.
17074 * xml.c (make_dom): Now static.
17076 * composite.c (composition_compute_stop_pos): Rename local to
17078 (composition_reseat_it): Remove unused locals.
17079 (find_automatic_composition, composition_adjust_point): Likewise.
17080 (composition_update_it): Mark var as initialized.
17081 (find_automatic_composition): Mark vars as initialized,
17082 with a FIXME (Bug#8290).
17084 character.h: Rename locals to avoid shadowing.
17085 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
17086 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
17087 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
17088 (BUF_DEC_POS): Be more systematic about renaming local temporaries
17089 to avoid shadowing.
17091 * textprop.c (property_change_between_p): Remove; unused.
17093 * intervals.c (interval_start_pos): Now static.
17095 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

17098 Rename locals to avoid shadowing.
17100 * sound.c (wav_play, au_play, Fplay_sound_internal):
17101 Fix pointer signedness.
17102 (alsa_choose_format): Remove unused local var.
17103 (wav_play): Initialize a variable to 0, to prevent undefined
17104 behavior (Bug#8278).
17106 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
17108 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
17110 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
17111 clobbering (Bug#8298).
17112 * sysdep.c (sys_subshell): Likewise.
17113 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
17115 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
17116 This should get cleaned up, so that child_setup has the
17117 same signature on all platforms.
17119 * callproc.c (call_process_cleanup): Now static.
17120 (relocate_fd): Rename locals to avoid shadowing.
17122 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
17124 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
17125 not to be necessary, and produces flickering.
17127 2011-03-20 Glenn Morris <rgm@gnu.org>
17129 * config.in: Remove file.
17131 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
17133 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
17134 are now in src/globals.h.
17135 (syms_of_minibuf): Remove spurious & from previous change.
17137 2011-03-20 Leo Liu <sdl.web@gmail.com>
17139 * minibuf.c (completing-read-function): New variable.
17140 (completing-read-default): Rename from completing-read.
17141 (completing-read): Call completing-read-function.
17143 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
17145 * xfaces.c (Fx_load_color_file):
17146 Read color file from absolute filename (bug#8250).
17148 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
17150 * makefile.w32-in: Update dependencies.
17152 2011-03-17 Eli Zaretskii <eliz@gnu.org>
17154 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

17161 (sigchld_handler): Now static.
17163 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
17164 That way, the code declares only the vars that it needs.
17165 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
17166 * s/cygwin.h (PTY_ITERATION): Likewise.
17167 * s/darwin.h (PTY_ITERATION): Likewise.

17171 * process.c (allocate_pty): Don't declare stb unless it's needed.
17173 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
17174 (CONSTANTLIM): Remove; unused.
17175 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
17176 Define only if needed.
17178 * unexelf.c (unexec): Name an expression,
17179 to avoid gcc -Wbad-function-cast warning.
17180 Use a different way to cause a compilation error if anyone uses
17181 n rather than nn, a way that does not involve shadowing.
17182 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
17184 * deps.mk (unexalpha.o): Remove; unused.
17186 New file unexec.h, the (simple) interface for unexec (Bug#8267).
17187 * unexec.h: New file.
17188 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
17189 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
17190 Depend on unexec.h.
17191 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
17192 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
17193 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
17194 Change as necessary to match prototype in unexec.h.
17196 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
17198 (back_comment, skip_chars): Mark vars as initialized.

17206 * print.c (Fredirect_debugging_output): Fix pointer signedess.
17208 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
17209 warning when compiling print.c.

17212 instead of using an uninitialized var.
17213 (font_sort_entities): Mark var as initialized.
17215 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
17217 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

17229 * floatfns.c (domain_error2): Define only if needed.
17230 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
17232 * alloc.c (mark_backtrace): Move decl from here ...
17233 * lisp.h: ... to here, so that it can be checked.
17235 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
17236 (Fdefvar): Rewrite so as not to use empty "else".

17241 * callint.c (quotify_arg, quotify_args): Now static.
17242 (Fcall_interactively): Rename locals to avoid shadowing.
17243 Use const pointer when appropriate.
17245 * lisp.h (get_system_name, get_operating_system_release):

17249 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
17250 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
17251 some of which prompt warnings from gcc -Wbad-function-cast.
17252 (Fformat_time_string, Fencode_time, Finsert_char):
17253 (Ftranslate_region_internal, Fformat):
17254 Rename or remove local vars to avoid shadowing.
17255 (Ftranslate_region_internal): Mark var as initialized.
17257 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
17260 * lisp.h (eassert): Check that the argument compiles, even if
17261 ENABLE_CHECKING is not defined.
17263 * data.c (Findirect_variable): Name an expression, to avoid
17264 gcc -Wbad-function-cast warning.

17272 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
17273 Rename locals to avoid shadowing.
17274 (mark_stack): Move local variables into the #ifdef region where
17276 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
17277 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
17279 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
17280 (GC_STRING_CHARS): Remove; not used.
17281 (Fmemory_limit): Cast sbrk's returned value to char *.
17283 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
17284 avoids undefined behavior in theory.
17286 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
17288 Use functions, not macros, for up- and down-casing (Bug#8254).
17289 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17290 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
17291 to use the following functions instead of these macros.
17292 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
17293 EMACS_INT, since callers assume the returned value fits in int.
17294 (upcase1): Likewise, for UPCASE_TABLE.
17295 (uppercasep, lowercasep, upcase): New static inline functions.
17296 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
17297 the race-condition problem in the old DOWNCASE.
17299 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
17300 Rename locals to avoid shadowing.
17301 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
17302 (regex_compile, re_search_2, re_match_2_internal):
17303 Remove unused local vars.
17304 (FREE_VAR): Rewrite so as not to use empty "else",
17305 which gcc can warn about.
17306 (regex_compile, re_match_2_internal): Mark locals as initialized.
17307 (RETALLOC_IF): Define only if needed.
17308 (WORDCHAR_P): Likewise. This one is never needed, but is used
17309 only in a comment talking about a compiler bug, so put inside
17310 the #if 0 of that comment.
17311 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
17312 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
17315 * search.c (boyer_moore): Rename locals to avoid shadowing.
17316 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
17317 (PREV_CHAR_BOUNDARY): Likewise.
17319 * search.c (simple_search): Remove unused var.
17321 * dired.c (compile_pattern): Move decl from here ...

17327 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
17329 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
17330 Rename locals to avoid shadowing.
17331 (Fvertical_motion): Mark locals as initialized.
17333 * casefiddle.c (casify_object, casify_region): Now static.
17334 (casify_region): Mark local as initialized.
17336 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
17338 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
17339 New macros, so that the caller can use some names other than
17340 gcpro1, gcpro2, etc.
17341 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
17343 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
17344 argument, for consistency with GCPRO2_VAR, etc: it is now the
17345 prefix of the variable, not the variable itself. All uses
17347 * dired.c (directory_files_internal, file_name_completion):
17348 Rename locals to avoid shadowing.
17350 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
17351 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
17352 dired.c's scmp function, had undefined behavior.
17353 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17354 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
17355 * buffer.h: ... to here, because these macros use current_buffer,
17356 and the new implementation with inline functions needs to have
17357 current_buffer in scope now, rather than later when the macros
17359 (downcase, upcase1): New static inline functions.
17360 (DOWNCASE, UPCASE1): Reimplement using these functions.
17361 This avoids undefined behavior in expressions like
17362 DOWNCASE (x) == DOWNCASE (y), which previously suffered
17363 from race conditions in accessing the global variables
17364 case_temp1 and case_temp2.
17365 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
17366 * lisp.h (case_temp1, case_temp2): Remove their decls.
17367 * character.h (ASCII_CHAR_P): Move from here ...
17368 * lisp.h: ... to here, so that the inline functions mentioned
17369 above can use them.
17371 * dired.c (directory_files_internal_unwind): Now static.
17373 * fileio.c (file_name_as_directory, directory_file_name):
17374 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
17376 (file_name_as_directory): Use const pointers when appropriate.
17377 (Fexpand_file_name): Likewise. In particular, newdir might
17378 point at constant storage, so make it a const pointer.
17379 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
17380 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
17382 (Fset_file_times, Finsert_file_contents, auto_save_error):
17383 Rename locals to avoid shadowing.
17385 * minibuf.c (choose_minibuf_frame_1): Now static.
17386 (Ftry_completion, Fall_completions): Rename or remove locals
17387 to avoid shadowing.
17389 * marker.c (bytepos_to_charpos): Remove; unused.

17813 is actually in tparam.c. The previous trick of using incompatible
17814 decls in different modules does not conform to the C standard.
17815 All callers of tparam changed to use tparam's actual API.
17816 * tparam.c (tparam1, tparam, tgoto):
17817 Use const pointers where appropriate.

17825 (turn_on_face, init_tty): Likewise.
17826 * termchar.h (struct tty_display_info): Likewise.
17828 * term.c (term_mouse_position): Rename local to avoid shadowing.
17830 * alloc.c (mark_ttys): Move decl from here ...
17831 * lisp.h (mark_ttys): ... to here, so that it's checked against defn.
