11 * image.c: Omit unnecessary static decls.
12 (x_create_bitmap_mask, x_build_heuristic_mask):
13 Return void, not int, since callers don't care about the return value.

51 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
52 (interruptible_wait_for_termination):
53 Move these decls from lisp.h to syswait.h, since they use pid_t.
54 Needed on FreeBSD; see Herbert J. Skuhra in
55 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
56 * callproc.c: Include syswait.h.

102 2012-09-23 Eli Zaretskii <eliz@gnu.org>
104 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
105 fatal_error_backtrace.
107 * w32proc.c (sys_kill): Undo last change: don't do anything when
108 invoked to deliver SIGABRT to our own process. This is now
109 handled by emacs_raise.
111 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
113 * w32term.c (w32_read_socket): Remove leftover reference to
114 interrupt_input_pending.
116 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
118 Do not use SA_NODEFER.
119 Problem reported by Dani Moncayo in
120 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
122 * sysdep.c (emacs_abort): Do not reset signal handler.
123 * emacs.c (terminate_due_to_signal): Reset signal handler here.
124 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
125 wanted even on POSIXish hosts, and it doesn't work on Windows.
127 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
129 * xterm.c (x_term_init): Call fixup_locale before and after calling
130 gtk_init (Bug#12392).
132 2012-09-23 Chong Yidong <cyd@gnu.org>
134 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
135 Vdynamic_library_alist.
137 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
138 (Fgnutls_available_p): Caller changed.
140 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
141 (Flibxml_parse_xml_region): Likewise.

147 (init_xpm_functions, init_png_functions, init_jpeg_functions)
148 (init_tiff_functions, init_gif_functions, init_svg_functions):
149 Arglist and w32_delayed_load calling convention changed.
150 (gs_type): Remove init_gs_functions; there is no such function.
151 (valid_image_p, make_image): Fix caller to lookup_image_type.
153 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
155 Simplify and avoid signal-handling races (Bug#12471).
157 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
158 Avoid recursive loop if there's a fatal error in the function itself.
159 * atimer.c (pending_atimers):
160 * blockinput.h: Don't include "atimer.h"; no longer needed.
161 (interrupt_input_pending): Remove. All uses removed.
162 pending_signals now counts both atimers and ordinary interrupts.
163 This is less racy than having three separate pending-signal flags.
164 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
166 Rename from their upper-case counterparts BLOCK_INPUT,
167 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
168 INPUT_BLOCKED_P, and turn into functions. All uses changed.
169 This makes it easier to access volatile variables more accurately.
170 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
171 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
172 that's more reliable if the code is buggy and sets
173 interrupt_input_blocked to a negative value. All uses changed.
174 * atimer.c (deliver_alarm_signal):
175 Remove. No need to deliver this to the parent; any thread can
176 handle this signal now. All uses replaced by underlying handler.
177 * atimer.c (turn_on_atimers):
178 * dispnew.c (handle_window_change_signal):
179 * emacs.c (handle_danger_signal):
180 * keyboard.c (kbd_buffer_get_event):
181 Don't reestablish signal handler; not needed with sigaction.
182 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
184 Rework to avoid unnecessary accesses to volatile variables.
185 (UNBLOCK_INPUT_TO): Now a function.
186 (totally_unblock_input, unblock_input): New decls.
187 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
188 (init_data): Remove. Necessary stuff now done in init_signal.
189 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
190 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
191 (fatal_error_code): Remove; no longer needed.
192 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
193 it doesn't always backtrace. All uses changed. No need to reset
194 signal to default, since sigaction and/or die does that for us now.
195 Use emacs_raise (FOO), not kill (getpid (), FOO).
196 (main): Check more-accurately whether we're dumping.
197 Move fatal-error setup to sysdep.c
198 * floatfns.c: Do not include "syssignal.h"; no longer needed.
199 * gtkutil.c (xg_get_file_name, xg_get_font):
200 Remove no-longer-needed signal-mask manipulation.
201 * keyboard.c, process.c (POLL_FOR_INPUT):
202 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
203 * keyboard.c (read_avail_input): Remove.
204 All uses replaced by gobble_input.
205 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
206 (kbd_buffer_store_event_hold, gobble_input):
207 (record_asynch_buffer_change) [USABLE_SIGIO]:
208 (store_user_signal_events):
209 No need to mess with signal mask.
210 (gobble_input): If blocking input and there are terminals, simply
211 set pending_signals to 1 and return. All hooks changed to not
212 worry about whether input is blocked.
213 (process_pending_signals): Clear pending_signals before processing
214 them, in case a signal comes in while we're processing.
215 By convention callers now test pending_signals before calling us.
216 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
217 New functions, to support changes to blockinput.h.
218 (handle_input_available_signal): Now extern.
219 (reinvoke_input_signal): Remove. All uses replaced by
221 (quit_count): Now volatile, since a signal handler uses it.
222 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg. All
223 callers changed. Block SIGINT only if not already blocked.
224 Clear sigmask reliably, even if Fsignal returns, which it can.
225 Omit unnecessary accesses to volatile var.
226 (quit_throw_to_read_char): No need to restore sigmask.
227 * keyboard.c (gobble_input, handle_user_signal):
228 * process.c (wait_reading_process_output):
229 Call signal-handling code rather than killing ourselves.
230 * lisp.h: Include <float.h>, for...
231 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
232 (pending_signals): Now volatile.
233 (syms_of_data): Now const if IEEE floating point.
234 (handle_input_available_signal) [USABLE_SIGIO]:
235 (terminate_due_to_signal, record_child_status_change): New decls.
236 * process.c (create_process): Avoid disaster if memory is exhausted
237 while we're processing a vfork, by tightening the critical section
239 (send_process_frame, process_sent_to, handle_pipe_signal)
240 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
242 (send_process): No need for setjmp/longjmp any more, since the
243 SIGPIPE stuff is now gone. Instead, report an error if errno
245 (record_child_status_change): Now extern. PID and W are now args.
246 Return void, not bool. All callers changed.
247 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
248 Remove. All uses removed. This bug should be fixed now in a
250 (wait_for_termination_1): Use waitpid rather than sigsuspend,
251 and record the child status change directly. This avoids the
252 need to futz with the signal mask.
253 (process_fatal_action): Move here from emacs.c.
254 (emacs_sigaction_flags): New function, containing
255 much of what used to be in emacs_sigaction_init.
256 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
257 caught by emacs, to make races less likely.
258 (deliver_process_signal): Rename from handle_on_main_thread.
260 (BACKTRACE_LIMIT_MAX): Now at top level.
261 (thread_backtrace_buffer, threadback_backtrace_pointers):
263 (deliver_thread_signal, deliver_fatal_thread_signal):
264 New functions, for more-accurate delivery of thread-specific signals.
265 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
266 (deliver_arith_signal): Handle in this thread, not
267 in the main thread, since it's triggered by this thread.
268 (maybe_fatal_sig): New function.
269 (init_signals): New arg DUMPING so that we can be more accurate
270 about whether we're dumping. Caller changed.
271 Treat thread-specific signals differently from process-general signals.
272 Block all signals while handling fatal error; that's safer.
273 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
275 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
276 Ignore SIGPIPE unless batch.
277 (emacs_backtrace): Output backtrace for the appropriate thread,
278 which is not necessarily the main thread.
279 * syssignal.h: Include <stdbool.h>.
280 (emacs_raise): New macro.
281 * xterm.c (x_connection_signal): Remove; no longer needed
282 now that we use sigaction.
283 (x_connection_closed): No need to mess with sigmask now.
284 (x_initialize): No need to reset SIGPIPE handler here, since
285 init_signals does this for us now.
287 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
289 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
290 background rect may be larger (Bug#12445).
292 2012-09-23 Chong Yidong <cyd@gnu.org>
294 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
296 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
298 * .gdbinit: Just stop at fatal_error_backtrace.
299 See Stefan Monnier's request in
300 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
301 Remove no-longer-used query of system type.
303 2012-09-22 Chong Yidong <cyd@gnu.org>
305 * search.c (Freplace_match): Doc fix (Bug#12325).

322 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
323 (gif_type, imagemagick_type, svg_type, gs_type): Add
324 initialization functions.
325 (Finit_image_library): Call lookup_image_type.
326 (CHECK_LIB_AVAILABLE): Macro deleted.
327 (lookup_image_type): Call define_image_type here, rather than via
328 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
329 (syms_of_image): Move define_image_type calls for xbm_type and
330 pbm_type to lookup_image_type.
332 2012-09-22 Eli Zaretskii <eliz@gnu.org>
334 * keyboard.c (timer_check_2): Move calculation of 'timers' and
335 'idle_timers' from here ...
336 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
337 lists, to avoid infloops when the timer does something stupid,
338 like reinvoke itself with the same or smaller time-out.
341 2012-09-22 Martin Rudalics <rudalics@gmx.at>
343 * window.c (Fsplit_window_internal): Handle only Qt value of

356 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
357 or that fprintf is async-signal-safe. POSIX doesn't require
360 2012-09-22 Chong Yidong <cyd@gnu.org>
362 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
365 2012-09-22 Kenichi Handa <handa@gnu.org>
367 * composite.c (composition_reseat_it): Handle the case that a
368 grapheme cluster is not covered by a single font (Bug#12352).
370 2012-09-21 Chong Yidong <cyd@gnu.org>
372 * image.c (define_image_type): Avoid adding duplicate types to
373 image_types (Bug#12463). Suggested by Jörg Walter.
375 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
377 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
378 (print_load_command_name): Add case LC_DATA_IN_CODE.
379 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.

390 (Fset_file_selinux_context): Likewise. (Bug#12444)
392 2012-09-21 Eli Zaretskii <eliz@gnu.org>
394 * xdisp.c (try_window_reusing_current_matrix): Under bidi
395 reordering, locate the cursor by calling set_cursor_from_row; if
396 that fails, clear the desired glyph matrix before returning a
397 failure indication to the caller. Fixes leaving garbled display
398 when fast scrolling with a down-key. (Bug#12403)
399 (compute_stop_pos_backwards): Fix a typo that caused crashes while
400 scrolling through multibyte text.
402 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
404 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
405 calling mark_vectorlike since that's the one that marks the window.
406 (mark_discard_killed_buffers): Mark the final cdr.
407 * window.h (struct window): Move prev/next_buffers to the
409 * window.c (make_window): Initialize prev/next_buffers manually.

418 * w32term.c (w32_read_socket):
419 * xterm.c (XTread_socket):
420 Omit unused arg EXPECTED. All callers changed.
421 (store_user_signal_events): Return void, not int, since callers no
422 longer care about the return value. All uses changed.
424 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
426 * w32gui.h (XParseGeometry): Do not declare.
428 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
430 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
431 Ignore 'expected'. See Eli Zaretskii in

452 * search.c (scan_buffer): Use character positions in calls to
453 region_cache_forward and region_cache_backward, not byte
454 positions. (Bug#12196)
456 * w32term.c (w32_read_socket): Set pending_signals to 1, like
457 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
459 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
460 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
461 emacs_blocked_malloc, now deleted.
463 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
465 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
466 The workaround was for improving performance on Solaris 2.4, but
467 is getting in the way now. Emacs will still work if someone is
468 still running Solaris 2.4 in a museum somewhere; Sun dropped
469 support for Solaris 2.4 in 2003.
470 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
471 * process.c (create_process) [HAVE_WORKING_VFORK]:
472 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
473 since Emacs no longer uses vfork on that platform.
475 2012-09-17 Glenn Morris <rgm@gnu.org>
477 * emacs.c: Use COPYRIGHT.
479 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
481 Remove configure's --without-sync-input option (Bug#12450).
482 When auditing signal-handling in preparation for cleaning it up,
483 I found that SYNC_INPUT has race conditions and would be a real
484 pain to fix. Since it's an undocumented and deprecated
485 configure-time option, now seems like a good time to remove it.
486 Also see <http://bugs.gnu.org/11080#16>.
487 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
488 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
489 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
491 (check_depth) [XMALLOC_OVERRUN_CHECK]:
492 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
493 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
494 (dont_register_blocks, bytes_used_when_reconsidered)
495 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
496 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
497 [!SYSTEM_MALLOC && !SYNC_INPUT]:
498 Remove. All uses removed.
499 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
500 implementation, one that depends on whether the new macro
501 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
503 * atimer.c (run_timers, handle_alarm_signal):
504 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
505 (handle_async_input, process_pending_signals)
506 (handle_input_available_signal, init_keyboard):
507 * nsterm.m (ns_read_socket):
508 * process.c (wait_reading_process_output):
509 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
510 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
512 * xterm.c (XTread_socket):
514 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
515 * eval.c (handling_signal): Remove. All uses removed.
516 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
517 All uses replaced with the SYNC_INPUT version.
518 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
520 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
523 * font.c (Ffont_shape_gstring): Remove unused local.
525 2012-09-16 Glenn Morris <rgm@gnu.org>
527 * Makefile.in (clean): No longer run nextstep's clean.
529 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
531 (ns-app): Move here from ns.mk, and simplify.
532 (clean): Simplify nextstep entry.
533 * ns.mk: Remove file.
535 2012-09-17 Kenichi Handa <handa@gnu.org>
537 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
538 not covert the last few charactes.
540 2012-09-16 Kenichi Handa <handa@gnu.org>
542 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
543 here, but just check the validity of glyphs in the glyph-string.
545 2012-09-16 Martin Rudalics <rudalics@gmx.at>
547 * window.c (Fwindow_parameter, Fset_window_parameter): Accept
548 any window as argument (Bug#12452).
550 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
552 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
553 to ns_term_init to avoid memory leak.
555 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
556 explicit retain/release.
557 (ns_term_init): Only allow one display. Initialize outerpool and
560 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
562 Port _setjmp fix to POSIXish hosts as well as Microsoft.
563 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
564 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
565 the Microsoft problem in a different way, by altering ../nt/config.nt.
567 2012-09-15 Eli Zaretskii <eliz@gnu.org>
582 * w16select.c: Remove inclusion of setjmp.h, as it is now included
583 by lisp.h. This completes removal of setjmp.h inclusion
584 erroneously announced in the previous commit. (Bug#12446)
586 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
589 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
590 not defined as a macro. The latter happens on MS-Windows.
593 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
595 Port better to POSIX hosts lacking _setjmp (Bug#12446).
596 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
597 Some instances of '#include <setjmp.h>' removed, if the
598 only reason for the instance was because "lisp.h" was included.
599 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
600 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
601 and _longjmp with the new symbols. Emacs already uses _setjmp if
602 available, so this change affects only POSIXish hosts that have
603 sigsetjmp but not _setjmp, such as some versions of Solaris and
604 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
605 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
606 (png_load_body) [HAVE_PNG]:
607 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
608 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
609 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
610 since PNG requires jmp_buf. This is the only exception to the
611 general rule that we now use sys_setjmp and sys_longjmp.
612 This exception is OK since this code does not change the signal
613 mask or longjmp out of a signal handler.
615 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
617 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
618 Include "syssignal.h", for 'main_thread'.
620 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
622 Avoid out-of-range marker position (Bug#12426).
623 * insdel.c (replace_range, replace_range_2): Adjust
624 markers before overlays, as suggested by comments.
625 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
626 Remove redundant check before calling offset_intervals.
628 2012-09-14 Martin Rudalics <rudalics@gmx.at>
630 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
631 current buffer (Bug#12387).
633 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
635 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
637 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
639 Use a more backwards-compatible timer format (Bug#12430).
640 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
641 vector element, not from the 4th, since PSECS is now at the end.
642 (Fcurrent_idle_time): Doc fix.
644 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
646 Function to mark objects and remove killed buffers at once.
647 * alloc.c (discard_killed_buffers): Rename to ...
648 (mark_discard_killed buffers) ... new name. Add marking
649 of remaining objects. Fix comment. Adjust users.
650 (mark_object): Do not touch frame buffer lists here.
651 * frame.c (delete_frame): Reset frame buffer lists here.
653 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
655 Better workaround for GNOME bug when --enable-gcc-warnings.
656 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
657 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
658 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
660 Simplify SIGIO usage (Bug#12408).
661 The code that dealt with SIGIO was crufty and confusing, e.g., it
662 played tricks like "#undef SIGIO" but these tricks were not used
663 consistently. Simplify mostly by not #undeffing standard symbols,
664 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
665 or not as we please) rather than "defined SIGIO" (standard symbol
666 that we probably shouldn't #undef).
667 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
668 Modules that need it can include it.
669 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
670 * dispextern.h (ignore_sigio): New decl.
671 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
672 unconditionally, since it's now a no-op if !USABLE_SIGIO.
673 * emacs.c (shut_down_emacs):
674 * keyboard.c (kbd_buffer_store_event_hold):
675 Use ignore_sigio rather than invoking 'signal' directly.
676 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
678 (FIONREAD, SIGIO): Do not #undef.
679 (tty_read_avail_input): Use #error rather than a syntax error.
680 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
681 for I_PIPE, used by SETUP_SLAVE_PTY.
682 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
683 * sysdep.c (croak): Remove; no longer needed. This bit of
684 temporary code, with Fred N. Fish's comment that it's temporary,
685 has been in Emacs since at least 1992!
686 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
687 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
688 * syssignal.h (croak): Remove decl.
689 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
690 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
691 now that we're termios-only.
692 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
693 * term.c (dissociate_if_controlling_tty): Use #error rather than
696 Work around GCC and GNOME bugs when --enable-gcc-warnings.
697 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
698 to work around GNOME bug 683906.
699 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
700 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
701 This works around GCC bug 54561.
703 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
705 More fixes for 'volatile' and setjmp/longjmp.
706 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
707 * image.c (struct png_load_context) [HAVE_PNG]: New type.
708 (png_load_body) [HAVE_PNG]:
709 (jpeg_load_body) [HAVE_JPEG]:
710 New function, with most of the old parent function's body.
711 (png_load) [HAVE_PNG]:
712 (jpeg_load) [HAVE_JPEG]:
713 Invoke the new function, to avoid longjmp munging our locals.
714 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
715 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
716 longjmp is passed 2, as the C standard doesn't guarantee this.
717 Instead, store the failure code into mgr->failure_code.
719 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
721 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
722 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
723 (syms_of_keyboard): Remove support for unread-command-char.
725 2012-09-12 Eli Zaretskii <eliz@gnu.org>
727 * w32proc.c (sys_kill): If PID is our process ID and the signal is
728 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
729 violation. (Bug#12426)
731 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
733 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
735 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
737 * eval.c: Add `inhibit-debugger'.
738 (Qinhibit_debugger): New symbol.
739 (call_debugger): Bind it instead of Qdebug_on_error.
740 (maybe_call_debugger): Test Vinhibit_debugger.
741 (syms_of_eval): Define inhibit-debugger.
742 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
743 (syms_of_xdisp): Remove inhibit-debug-on-message.
745 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
747 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
748 If a nonvolatile local variable is written before a _longjmp to
749 the frame containing the variable, and is read after the _longjmp,
750 the value read is indeterminate. Some local variables of type
751 'struct handler' and 'struct catchtag' are used in this way, so
752 mark each of their slots as volatile if the slot can be set before
753 _longjmp and read afterwards.
754 * lisp.h (struct handler): var and chosen_clause are now volatile.
755 (struct catchtag): val, next, and pdlcount are now volatile.
757 * bidi.c (bidi_push_it, bidi_pop_it):
758 * fns.c (copy_hash_table):
759 * image.c (define_image_type):
760 * keyboard.c (kbd_buffer_store_event_hold):
761 * process.c (Fprocess_send_eof):
762 * xfaces.c (x_create_gc) [HAVE_NS]:
763 * xgselect.c (xg_select):
764 Prefer assignment to memcpy when either will do.
766 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
767 Use pointer-to-a-pointer to simplify and avoid a NILP check each
768 time an item is removed. No need to mark this function 'inline';
769 the compiler knows better than we do.
771 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
773 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
774 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
775 to change_frame_size (Bug#12388).
776 (windowDidResize:): Pass YES to updateFrameSize.
778 * nsterm.h: Add delay parameter to updateFrameSize.
780 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
782 Discard killed buffers from deleted window and frame objects.
783 This reduces an amount of references to killed buffers and
784 helps GC to reclaim them faster.
785 * alloc.c (discard_killed_buffers): New function.
786 (mark_object): Use it for deleted windows and frames.
787 (mark_object): If symbol's value is set up for a killed buffer
788 or deleted frame, restore it's global binding.
789 * data.c (swap_in_global_binding): Add GC notice.
790 (swap_in_symval_forwarding): Use convenient set_blv_where.
791 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
792 * window.h: ... to here.
794 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
796 Convenient macro to check whether the buffer is live.
797 * buffer.h (BUFFER_LIVE_P): New macro.
798 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
799 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
801 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
803 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
804 composition cases (Bug#12364).
806 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
807 overhang of succeeding glyphs overlapping box cursor.
809 * w32term.c (x_draw_glyph_string): Likewise.
811 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
813 Simplify, document, and port floating-point (Bug#12381).
814 The porting part of this patch fixes bugs on non-IEEE platforms
815 with frexp, ldexp, logb.
816 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
818 * floatfns.c: Simplify discussion of functions that Emacs doesn't
819 support, by removing commented-out code and briefly listing the
820 C89 functions excluded. The commented-out stuff was confusing
821 maintenance, e.g., we thought we needed cbrt but it was commented out.
822 (logb): Remove decl; no longer needed.
823 (isfinite): New macro, if not already supplied.
824 (isnan): Don't replace any existing macro.
825 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
826 are present on all C89 platforms.
827 (Ffrexp): Do not special-case zero, as frexp does the right thing
829 (Flogb): Do not use logb, as it doesn't have the desired meaning
830 on hosts that use non-base-2 floating point. Instead, stick with
831 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
832 frexp, to avoid getting an unspecified result.
834 * xdisp.c (Qinhibit_debug_on_message): Now static.
836 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
838 * nsterm.m (ns_update_begin): Set clip path to whole view by using
839 NSBezierPath (Bug#12131).
841 2012-09-10 Chong Yidong <cyd@gnu.org>
843 * fns.c (Fdelq, Fdelete): Doc fix.
845 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
847 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
848 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
850 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
852 * lisp.h (make_lisp_ptr): New macro to replace XSET.
853 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
856 2012-09-09 Eli Zaretskii <eliz@gnu.org>
858 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
859 left fringe if the window has a left margin. This avoids leaving
860 traces of the cursor because its leftmost pixel is not drawn over.
862 * dispnew.c (update_window_line): When the left margin area of a
863 screen line is updated, set the redraw_fringe_bitmaps_p flag of
864 that screen line. (Bug#12277)
866 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
868 Assume C89 or later for math functions (Bug#12381).
869 This simplifies the code, and makes it a bit smaller and faster,
870 and (most important) makes it easier to clean up signal handling
871 since we can stop worring about floating-point exceptions in
872 library code. That was a problem before C89, but the problem
873 went away many years ago on all practical Emacs targets.
874 * data.c, image.c, lread.c, print.c:
875 Don't include <math.h>; no longer needed.
876 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
877 might be autoconfigured, as that never happens.
879 * doprnt.c (DBL_MAX_10_EXP):
881 Remove. C89 or later always defines these.
882 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
883 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
884 (arith_error, domain_error, domain_error2):
885 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
886 no longer needed -- we simply return what C returns. All uses removed.
887 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
889 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
890 Remove. All uses expanded, as these macros are no longer used
891 more than once and are now more trouble than they're worth.
892 (Ftan): Use tan, not sin / cos.
893 (Flogb): Assume C89 frexp.
894 (fmod_float): Assume C89 fmod.
895 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
896 (init_floatfns): Remove. All uses removed.
898 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
900 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
901 compositeToPoint for OSX < 10.6 (Bug#12390).
903 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
905 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
906 This produces more-accurate results.
908 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
910 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
913 2012-09-08 Chong Yidong <cyd@gnu.org>
915 * syntax.c (Fstring_to_syntax): Doc fix.
917 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
919 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
920 in the internal border.
921 (x_set_window_size): Remove static variables and their usage.
922 (ns_redraw_scroll_bars): Fix NSTRACE arg.
923 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
924 fringe/internal border adjustment (Bug#11052).
925 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
926 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
927 (ns_fix_rect_ibw): Remove.
928 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
929 (ns_dumpglyphs_box_or_relief): Ditto.
930 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
932 (ns_dumpglyphs_image): Ditto.
933 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
935 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
936 their usage. Add fringe_extended_p and its use as in other terms.
937 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
938 scroll bar was removed.
939 (updateFrameSize): New function.
940 (windowDidResize): Move code to updateFrameSize and call it.
942 * nsterm.h (EmacsView): Add updateFrameSize.
944 2012-09-07 Chong Yidong <cyd@gnu.org>
946 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
948 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
950 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
952 More signal-handler cleanup (Bug#12327).
953 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
954 Problem introduced when merging patches. Noted by Eli Zaretskii in
955 <http://bugs.gnu.org/12327#67>.
956 * floatfns.c: Comment fix.
957 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
958 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
959 and anyway the declaration is harmless even if SIGDANGER is not defined.
960 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
961 defined BROKEN_FIONREAD). systty.h formerly did this, but other
962 source files not surprisingly expected syssignal.h to define, or
963 not define, SIGIO, and it's cleaner to do it that way, for consistency.
964 Include <sys/ioctl.h>, for FIONREAD.
965 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
966 This eliminates a problem whereby other files mysteriously had
967 to include "syssignal.h" before including "systty.h" if they
968 wanted to use "#ifdef SIGIO".
970 2012-09-07 Eli Zaretskii <eliz@gnu.org>
972 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
974 * w32.c (sigemptyset): Empty the set.
975 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
977 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
979 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
981 * alloc.c (mark_buffer): Revert unsafe marking optimization.
982 (mark_object): Likewise for frame objects.
984 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
986 * syssignal.h (handle_on_main_thread): Always declare,
987 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
988 This ports to platforms without HAVE_PTHREAD.
990 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
992 Signal-handler cleanup (Bug#12327).
993 Emacs's signal handlers were written in the old 4.2BSD style with
994 sigblock and sigmask and so forth, and this led to some
995 inefficiencies and confusion. Rewrite these to use
996 pthread_sigmask etc. without copying signal sets around. Also,
997 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
998 'signal', and instead use functions that do not attempt to take
999 over the system name space. This patch causes Emacs's text
1000 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
1001 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
1002 Do not include <signal.h> or "syssignal.h", as these
1003 modules do not use signals.
1004 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
1005 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
1006 Do not include <signal.h>, as "syssignal.h" does that for us now.
1007 * atimer.c (sigmask_atimers): New function.
1008 (block_atimers, unblock_atimers): New functions,
1009 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
1011 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
1012 no longer needed here.
1013 * emacs.c (main): Inspect existing signal handler with sigaction,
1014 so that there's no need to block and unblock SIGHUP.
1015 * sysdep.c (struct save_signal): New member 'action', replacing
1016 old member 'handler'.
1017 (save_signal_handlers, restore_signal_handlers):
1018 Use sigaction instead of 'signal' to save and restore.
1019 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
1020 New function. All users of 'signal' modified to use set_sighandler
1021 if they're writeonly, and to use sys_signal if they're read+write.
1022 (emacs_sigaction_init, forwarded_signal): New functions.
1023 (sys_signal): Remove. All uses replaced by calls to sigaction
1024 and emacs_sigaction_init, or by direct calls to 'signal'.
1025 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
1026 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
1027 all uses replaced by pthread_sigmask etc. calls.
1028 * syssignal.h: Include <signal.h>.
1029 (emacs_sigaction_init, forwarded_signal): New decls.
1030 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
1031 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
1032 (sigmask, sys_sigmask): Remove; no longer needed.
1033 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
1034 (sigblock, sigunblock, sigfree):
1035 (sigsetmask) [!defined sigsetmask]:
1036 Remove. All uses replaced by pthread_sigmask.
1037 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
1038 no longer need to be replaced, and its typical old uses
1039 are now done via emacs_sigaction_init and sigaction.
1040 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
1041 (sys_sigdel): Remove; unused.
1042 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
1044 2012-09-06 Eli Zaretskii <eliz@gnu.org>
1046 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
1047 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
1049 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1051 Explicitly mark buffer_defaults and buffer_local_symbols.
1052 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
1053 mark_local_symbols here.
1054 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
1055 since special buffers aren't marked here any more.
1056 (allocate_buffer): Chain new buffer with all_buffers here...
1057 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
1059 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
1060 (syms_of_buffer): Remove staticpro of the above.
1061 (init_buffer_once): Set names for buffer_defaults and
1062 buffer_local_symbols.
1064 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1066 Use bool for booleans in font-related modules.
1067 * font.c (font_intern_prop, font_style_to_value)
1068 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
1069 (generate_otf_features, font_check_otf_features, font_check_otf)
1070 (font_match_p, font_list_entities, font_at):
1071 * fontset.c (fontset_id_valid_p, reorder_font_vector
1072 (fontset_find_font, Fset_fontset_font)
1073 (face_suitable_for_char_p) [0]:
1074 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
1075 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
1076 (m17n_flt_initialized, ftfont_shape_by_flt):
1077 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
1078 * nsfont.m (nsfont_draw):
1079 * w32font.c (w32font_draw):
1080 * w32term.c (x_draw_glyphless_glyph_string_foreground):
1081 Use bool for booleans.
1082 * font.h: Adjust to above API changes.
1083 (struct font, struct font_driver, struct font_driver_list):
1084 Use bool for booleans.
1085 (struct font): Remove useless member encoding_type.
1087 * fontset.c, xftfont.c: Omit unnecessary static decls.
1089 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1091 * alloc.c (mark_object): Revert window marking code
1092 since it's unsafe for the Fset_window_configuration.
1094 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1096 Fix race conditions with signal handlers and errno (Bug#12327).
1097 Be more systematic about preserving errno whenever a signal
1098 handler returns, even if it's not in the main thread. Do this by
1099 renaming signal handlers to distinguish between signal delivery
1100 and signal handling. All uses changed.
1101 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
1102 * data.c (deliver_arith_signal): Rename from arith_error.
1103 * dispnew.c (deliver_window_change_signal): Rename from
1104 window_change_signal.
1105 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
1106 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
1107 * keyboard.c (deliver_input_available_signal): Rename from
1108 input_available_signal.
1109 (deliver_user_signal): Rename from handle_user_signal.
1110 (deliver_interrupt_signal): Rename from interrupt_signal.
1111 * process.c (deliver_pipe_signal): Rename from send_process_trap.
1112 (deliver_child_signal): Rename from sigchld_handler.
1113 * atimer.c (handle_alarm_signal):
1114 * data.c (handle_arith_signal):
1115 * dispnew.c (handle_window_change_signal):
1116 * emacs.c (handle_fatal_signal, handle_danger_signal):
1117 * keyboard.c (handle_input_available_signal):
1118 * keyboard.c (handle_user_signal, handle_interrupt_signal):
1119 * process.c (handle_pipe_signal, handle_child_signal):
1120 New functions, with the actual signal-handling code taken from the
1121 original respective signal handlers, sans the sporadic attempts to
1122 preserve errno, since that's now done by handle_on_main_thread.
1123 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
1124 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
1125 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1127 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1128 Move initialization of main_thread to sysdep.c's init_signals.
1129 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
1130 our usage, and simplifies the mainline code.
1131 (record_child_status_change): New static function, as a helper
1132 for handle_child_signal, and with most of the old child handler's
1134 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
1135 (handle_child_signal): Use the above.
1136 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1137 Moved here from emacs.c.
1138 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
1139 code moved here from emacs.c's main function.
1140 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
1141 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
1142 lets callers save and restore errno properly.
1144 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1146 Remove redundant or unused things here and there.
1147 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
1148 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
1149 * editfns.c (Fcompare_buffer_substrings): Likewise.
1150 * frame.h (struct terminal, struct font_driver_list):
1151 Remove redundant declarations.
1152 * window.h (Qleft, Qright): Likewise.
1154 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1156 Do not mark objects from deleted buffers, windows and frames.
1157 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
1158 (mark_object): Likewise for windows and frames.
1160 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1162 * alloc.c (valid_lisp_object_p): Treat killed buffers,
1163 buffer_defaults and buffer_local_symbols as valid objects.
1164 Return special value to denote them.
1166 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1168 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
1169 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
1170 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
1171 (file_name_absolute_p, Fsubstitute_in_file_name):
1172 (check_executable, check_writable, Ffile_accessible_directory_p)
1173 (Fset_file_selinux_context, Fdefault_file_modes)
1174 (Finsert_file_contents, choose_write_coding_system)
1175 (Fwrite_region, build_annotations, a_write, e_write)
1177 * filelock.c (boot_time_initialized, get_boot_time)
1178 (get_boot_time_1, lock_file_1, within_one_second):
1179 * floatfns.c (in_float):
1180 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
1181 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
1182 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
1183 * lisp.h (struct Lisp_Hash_Table.cmpfn):
1184 * window.c (compare_window_configurations):
1185 Use bool for booleans.
1186 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
1187 (Fdefault_file_modes): Now mode_t, not int, for modes.
1188 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
1189 (internal_delete_file): Now returns void, not a (boolean) int,
1190 since nobody was looking at the return value.
1191 * lisp.h, window.h: Adjust to above API changes.
1193 * xdisp.c (set_message): Simplify and reindent last change.
1195 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
1197 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
1199 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
1201 * eval.c (call_debugger): Make the function non-static so that we
1202 can call it from set_message.
1204 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
1205 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
1207 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1209 Give more-useful info on a fatal error (Bug#12328).
1210 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
1211 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
1212 of doing the work ourselves.
1213 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
1214 do most of the work.
1215 (fatal_error_backtrace): New function, taken from the guts
1216 of the old fatal_error_signal, but with a new option to output
1218 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
1219 info about the signal than just its number.
1220 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
1221 * sysdep.c: Include <execinfo.h>
1222 (emacs_backtrace): New function, taken partly from the previous
1223 code of the 'die' function.
1224 (emacs_abort): Call fatal_error_backtrace rather than abort.
1226 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
1228 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
1229 eager (load-time) macro-expansion.
1230 * lisp.mk (lisp): Add macroexp.
1232 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1234 Simplify redefinition of 'abort' (Bug#12316).
1235 Do not try to redefine the 'abort' function. Instead, redo
1236 the code so that it calls 'emacs_abort' rather than 'abort'.
1237 This removes the need for the NO_ABORT configure-time macro
1238 and makes it easier to change the abort code to do a backtrace.
1239 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
1240 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
1241 Remove; sysdep.c's emacs_abort now takes its place.
1242 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
1243 'abort' changed to use 'emacs_abort'.
1244 * msdos.c (dos_abort) [defined abort]: Remove; not used.
1245 (abort) [!defined abort]: Rename to ...
1246 (emacs_abort): ... new name.
1247 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
1248 the place of the old 'abort' in emacs.c.
1249 * w32.c, w32fns.c (abort): Do not #undef.
1250 * w32.c (emacs_abort): Rename from w32_abort.
1252 2012-09-04 Eli Zaretskii <eliz@gnu.org>
1254 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
1255 offsets[j].dv, since the y axis of the screen coordinates points
1256 down, while the y axis of the font definition coordinates points
1257 up. This fixes display of Arabic diacritics such as KASRA and
1258 KASRATAN. (Bug#11860)
1260 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1262 Be more systematic about _setjmp vs setjmp.
1263 * alloc.c (test_setjmp, mark_stack):
1264 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
1265 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
1266 (png_load, my_error_exit, jpeg_load):
1267 * process.c (send_process_trap, send_process):
1268 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
1269 The underscored versions are up to 30x faster on some hosts.
1270 Formerly, the code used setjmp+longjmp sometimes and
1271 _setjmp+_longjmp at other times, with no particular reason to
1272 prefer setjmp+longjmp.
1274 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
1276 Fix minor problem found by static checking.
1277 * buffer.c (Fdelete_all_overlays): Return nil.
1279 2012-09-03 Martin Rudalics <rudalics@gmx.at>
1281 * buffer.c (Fdelete_all_overlays): New function.
1283 2012-09-03 Chong Yidong <cyd@gnu.org>
1285 * gtkutil.c: Add extern decl for Qxft.
1287 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
1289 * emacs.c, eval.c: Use bool for boolean.
1290 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
1291 (malloc_using_checking) [DOUG_LEA_MALLOC]:
1292 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
1293 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
1294 (main, decode_env_path, Fdaemon_initialized):
1295 * eval.c (call_debugger, Finteractive_p, interactive_p):
1296 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
1297 (maybe_call_debugger, Fbacktrace):
1298 * process.c (read_process_output, exec_sentinel):
1299 Use bool for booleans.
1300 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
1301 All callers changed.
1302 * eval.c (interactive_p): Omit always-true boolean argument
1303 EXCLUDE_SUBRS_P. All callers changed.
1304 * dispextern.h, lisp.h: Reflect above API changes.
1305 * firstfile.c (dummy): Use the address of 'main', whose signature
1306 won't change, instead of the address of 'initialize', whose
1307 signature just changed from int to bool.
1308 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
1309 * msdos.c (fatal_error_in_progress): ... from here.
1310 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
1312 (redisplay_internal, unwind_redisplay): Simply clear
1313 REDISPLAYING_P when unwinding, instead of saving its previous,
1314 always-false value and then restoring it.
1316 Clean up some extern decls.
1317 Mostly, this hoists extern decls out of .c files and into .h files.
1318 That way, we're more likely to catch errors if the interfaces change.
1319 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
1320 declare xg_mark_data.
1321 * dispextern.h (x_frame_parm_handlers):
1323 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
1324 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
1325 (Qultra_bold, Qoblique, Qitalic):
1326 Move extern decl here from .c file.
1327 * alloc.c (xg_mark_data) [USE_GTK]:
1329 * eval.c (Qlexical_binding):
1330 * fns.c (time) [!HAVE_UNISTD_H]:
1331 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
1332 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
1333 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
1334 * lread.c (Qinternal_interpreter_environment):
1335 * minibuf.c (Qbuffer):
1336 * process.c (QCfamily, QCfilter):
1337 * widget.c (free_frame_faces):
1338 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
1339 * xfont.c (x_clear_errors):
1340 * xterm.c (x_frame_parm_handlers):
1341 Remove now-redundant extern decls.
1342 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
1343 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
1345 * xfaces.c: Remove unnecessary static decls.
1346 * xterm.c (updating_frame): Remove decl of nonexistent object.
1348 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
1349 when building globals.h, as the objects that are not built on
1350 this host are not needed to compile C files on this host.
1352 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>

1406 offset adjustment values separately for each cluster. (Bug#11860)
1408 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1409 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1410 about implicit conversions from integer to pointer.

1468 window system declarations.
1470 * frame.h: Move common functions here: set_frame_menubar,
1471 x_set_window_size, x_sync, x_get_focus_frame,
1472 x_set_mouse_position, x_set_mouse_pixel_position,
1473 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

1530 for GCC 4.7.1 x86-64.
1532 2012-08-30 Glenn Morris <rgm@gnu.org>
1534 * lread.c (init_lread): For out-of-tree builds, only add the
1535 source directory's site-lisp dir to the load-path if it exists,
1536 consistent with in-tree builds. (Bug#12302)
1538 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

1772 It was meant to be temporary and it often doesn't work,
1773 because when IDX has side effects the behavior of IDX==IDX
1774 is undefined. See Stefan Monnier in

1801 Use bool for booleans, instead of int.
1803 2012-08-25 Eli Zaretskii <eliz@gnu.org>
1805 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
1807 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1809 On assertion failure, print backtrace if available.
1810 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1811 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1812 * Makefile.in (LIB_EXECINFO): New macro.
1815 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1816 * bytecode.c (exec_byte_code):
1817 * callint.c (check_mark, Fcall_interactively):
1818 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1819 (getenv_internal, sync_process_alive, call_process_exited):
1820 * lisp.h (USE_SAFE_ALLOCA):
1821 Use bool for booleans, instead of int.
1822 * lisp.h, process.h: Adjust prototypes to match above changes.
1823 * callint.c (Fcall_interactively): Don't assume the mark's
1824 offset fits in 'int'.
1826 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1828 * buffer.c, buffer.h: Use bool for boolean.
1829 * buffer.c (reset_buffer_local_variables)
1830 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1831 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
1832 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
1833 (overlay_touches_p, overlay_strings, Foverlay_put)
1834 (report_overlay_modification, call_overlay_mod_hooks):
1835 (mmap_enlarge, mmap_set_vars):
1836 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1837 Use bool for booleans, instead of int.
1838 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1839 since the 1-or-0 return value is always ignored anyway.
1840 (mmap_initialized_p):
1841 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1842 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1844 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1846 * bidi.c: Use bool for boolean.
1847 This is a bit more readable, and makes the text segment of bidi.o
1848 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1849 Presumably it's faster too.
1850 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1852 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1853 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1854 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1855 (bidi_explicit_dir_char, bidi_level_of_next_char)
1856 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1857 Use bool for booleans, instead of int.
1858 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1859 (bidi_unshelve_cache): Adjust decls to match code.
1861 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1863 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1866 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1868 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1869 * atimer.h: Include <stdbool.h>.
1871 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1873 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1874 compile time tests instead of run time tests on systems that do
1876 (FRAME_MAC_P): Remove leftover from deleted code.
1877 * frame.c (syms_of_frame): Remove leftover from deleted code.
1879 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>

1883 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1885 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1886 Otherwise, the compiler complains about (A?B:C) where B is void
1887 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1888 (fontset_add): Return void, for FONTSET_ADD.
1890 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1892 * alloc.c: Use bool for booleans.
1893 (gc_in_progress, abort_on_gc)
1894 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1895 (dont_register_blocks) [GC_MALLOC_CHECK]:
1896 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1897 (check_string_bytes, make_specified_string, memory_full)
1898 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1899 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1900 (mark_stack, valid_pointer_p, make_pure_string)
1901 (Fgarbage_collect, survives_gc_p, gc_sweep):
1902 Use bool for booleans, instead of int.
1903 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1904 Remove unused local.
1905 * alloc.c (PURE_POINTER_P):
1906 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1907 * editfns.c (Fformat):
1908 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1910 * fns.c (sweep_weak_table):
1911 * lisp.h (suppress_checking, push_message, survives_gc_p)
1912 (make_pure_string, gc_in_progress, abort_on_gc):
1913 * lread.c (readchar, read1):
1914 * print.c (Fprin1_to_string):
1915 * xdisp.c (push_message):
1916 Use bool for booleans affected directly or indirectly by
1919 Make recently-introduced setters macros.
1920 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1921 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1922 (set_fontset_default, set_fontset_fallback): Rename from their
1923 upper-case counterparts, and make them functions rather than macros.
1924 This is more consistent with the other recently-introduced setters.
1925 These don't need to be inline, since they're local.
1927 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1929 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1930 the loop (Bug#12247).
1932 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1934 * lisp.h (vcopy): Use memcpy rather than our own loop.
1935 This fixes a performance regression introduced by the recent
1936 addition of vcopy. This means 'vcopy' will need to be modified
1937 for a copying collector, but that's OK. Also, tighten the
1938 checking in the assertion.
1940 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1942 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1943 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1944 non-base glyph for the width of the base character, according to
1945 what x_draw_composite_glyph_string_foreground expects.
1946 Generate WADJUST value according to composition_gstring_width's
1947 expectations, to produce correct width of the composed character.
1948 Reverse the sign of the DU offset produced by ScriptPlace.
1950 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1952 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1954 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1956 Avoid direct writes to contents member of struct Lisp_Vector.
1957 * lisp.h (vcopy): New function to copy data into vector.
1958 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
1959 * fns.c (Ffillarray): Use ASET.
1960 * keyboard.c (timer_check_2): Use AREF and ASET.
1961 (append_tool_bar_item, Frecent_keys): Use vcopy.
1962 * lread.c (read_vector): Use ASET.
1963 * msdos.c (Frecent_doskeys): Use vcopy.

1971 the position of its buffer's point.
1972 (Fset_window_point): For the selected window always go in its
1973 buffer to the specified position.
1975 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1977 Setter macros for fontsets.
1978 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1979 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1980 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1983 2012-08-20 Glenn Morris <rgm@gnu.org>
1985 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1986 Don't assume that `ln -f' works.
1988 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1990 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1991 and later about non-assignments with no effect. See discussion at
1992 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1995 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1997 Inline setter functions for Lisp_Objects slots of struct specbinding.
1998 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
2001 2012-08-20 Martin Rudalics <rudalics@gmx.at>
2003 * window.c (select_window): Always make selected window's buffer
2006 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2008 Use AREF and ASET for docstrings of category tables.
2009 * category.h (CATEGORY_DOCSTRING): Use AREF.
2010 (SET_CATEGORY_DOCSTRING): Use ASET.
2011 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
2013 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2015 Inline setter functions for hash table members.
2016 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
2017 (set_hash_hash, set_hash_index): Rename with _slot suffix.
2018 (set_hash_key_and_value, set_hash_index, set_hash_next)
2019 (set_hash_hash): New functions.
2020 * charset.c, fns.c: Adjust users.
2022 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2024 Inline getter and setter functions for per-buffer values.
2025 * buffer.h (per_buffer_default, set_per_buffer_default)
2026 (per_buffer_value, set_per_buffer_value): New functions.
2027 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
2028 * buffer.c, data.c: Adjust users.
2030 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
2032 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
2034 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
2036 Rely on <config.h> + <unistd.h> to declare 'environ',
2037 as gnulib does this if the system doesn't.
2038 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
2039 Remove declaration. MS-Windows declares it on stdlib.h which is
2040 included by conf_post.h.
2041 * emacs.c (environ) [DOUG_LEA_MALLOC]:
2042 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
2043 * vm-limit.c: Include <unistd.h>, for 'environ'.
2045 * unexaix.c, unexcoff.c: Include "mem-limits.h".
2046 (start_of_data): Remove decl; mem-limits.h provides it.
2048 * xdisp.c (handle_invisible_prop): Make it a bit faster
2049 and avoid a gcc -Wmaybe-uninitialized diagnostic.
2051 2012-08-19 Chong Yidong <cyd@gnu.org>
2053 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string

2061 * data.c (set_internal): Don't use set_blv_found.
2062 (Fkill_local_variable): Likewise.
2064 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
2066 * nsfont.m (ns_ascii_average_width): Ensure the string
2067 ascii_printable is initialized with a null-terminated character
2068 array. Otherwise, it can contain undesired extra characters.

2073 * chartab.c, lisp.h (char_table_set, char_table_set_range):
2074 Return void, not Lisp_Object. Otherwise, the compiler
2075 complains about (A?B:C) where B is void and C is Lisp_Object
2076 when compiling CHAR_TABLE_SET, due to the recent change to
2077 the API of sub_char_table_set_contents.
2079 2012-08-18 Chong Yidong <cyd@gnu.org>
2081 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
2082 for the string case (Bug#3874).

2910 * w32.c (init_environment): Change the default values of many
2911 environment variables in dflt_envvars[] to NULL, to avoid pushing
2912 them into environment when they were not already defined.
2913 Remove the code that deletes site-lisp subdirectories from the default
2914 value of EMACSLOADPATH, as it is no longer needed.
2915 (check_windows_init_file): Now external, not static.
2916 Use Vload_path as is, without adding anything, as this function is now
2917 called when Vload_path is already set up.
2919 * w32.h (check_windows_init_file): Add prototype.
2921 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

2964 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
2965 Remove unnecessary pointer casts.
2966 * alloc.c (record_xmalloc): New function.
2967 * lisp.h (record_xmalloc): New decl.
2968 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
2969 more like a function. This is because the pointer cast is not
2970 needed. All uses changed.
2971 * print.c (print_string, print_error_message): Avoid length recalc.
2973 Improve fix for macroexp crash with debugging (Bug#12118).
2974 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
2975 ARRAY_MARK_FLAG when checking subscripts, because ASET is
2976 not supposed to be invoked from the garbage collector.

2978 (gc_aset): New function, which is like ASET but can be
2979 used in the garbage collector.

3008 with addition of handling of symlinks and support for 'lstat'.
3009 If possible, get file's attributes and security information by
3010 handle, not by name. Produce S_IFLNK bit for symlinks, when
3011 called from 'lstat'.
3012 (stat, lstat): New functions, call 'stat_worker'.
3013 (symlink, readlink, careadlinkat): Rewritten to create and resolve
3014 symlinks when the underlying filesystem supports them.
3016 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
3018 Fix macroexp crash on Windows with debugging (Bug#12118).
3019 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
3020 checking subscripts; problem introduced with the recent
3021 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
3022 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
3023 since it's used in non-static inline functions now.
3025 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
3026 Don't assume buffer size fits in 'int'. Remove unused local.

3046 * composite.c (COMPOSITE_INLINE):
3047 * dispnew.c (DISPEXTERN_INLINE):
3048 * sysdep.c (SYSTIME_INLINE):
3049 Define to EXTERN_INLINE, so that the corresponding functions
3050 are compiled into code.
3051 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
3052 (INLINE_HEADER_END): New macros.
3053 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

3073 hard-coding the path separator.
3075 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
3077 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
3078 This how ASET and AREF are supposed to work, and makes
3079 it easier to think about future improvements. See
3080 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
3081 * charset.h (set_charset_attr): New function.

3565 Reimplement to use struct Lisp_Excursion. Add comments.
3567 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
3569 Fix export of symbols to GDB (Bug#12036).
3570 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
3571 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
3572 emacs.c, as this is a more-suitable home. Had this been done earlier
3573 the fix for 12036 would have avoided some of the problems noted in
3574 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
3575 would have been more obvious.
3576 * emacs.c: Do not include <verify.h>; no longer needed.
3577 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
3578 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
3579 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3580 Remove; now done in lisp.h.
3581 * lisp.h (PUBLISH_TO_GDB): New macro.
3582 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
3583 (DATA_SEG_BITS): Use it.
3584 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
3585 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3586 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3587 not be usable in #if. This simplifies things.
3589 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
3591 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
3593 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

3596 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3597 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3598 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3599 Adjust to changes in lisp.h and emacs.c, by using
3600 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
3601 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
3602 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
3603 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
3604 instead of gdb_valbits.
3605 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
3606 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
3607 instead of gdb_array_mark_flag.
3608 (xboolvector): Get size from $->size, not $->header.size.
3609 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
3610 (xreload, hook-run, hookpost-run): Remove.
3611 * emacs.c: Include <verify.h>.
3612 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
3613 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
3615 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
3616 (gdb_USE_LSB_TAG): New enum constants.
3617 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3618 Also define these as enum constants, so they're visible to GDB.
3619 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
3620 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
3621 as constants, so they're visible to GDB.
3622 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
3623 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
3624 Now enum constants, not macros, so they're visible to GDB.
3625 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
3626 more convenient now. All uses changed.
3627 (VALMASK) [USE_LSB_TAG]: Also define in this case.
3628 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
3630 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
3632 Explicitly free restriction data that are not needed anymore.

3635 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
3637 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
3638 add argument, tune behavior, and adjust all callers.
3640 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
3642 Use typedef for EMACS_INT, EMACS_UINT.
3643 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
3644 than macros. This simplifies debugging in the usual case, since
3645 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
3646 and it allows expressions involving EMACS_INT casts.
3647 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
3649 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

3659 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
3661 Adjust buffer text indirection counters at the end of Fkill_buffer.
3662 * buffer.c (Fkill_buffer): Adjust indirection counters when the
3663 buffer is definitely dead. This should really fix an issue reported
3664 by Christoph Scholtes again. (Bug#12007).
3665 (init_buffer_once): Initialize indirection counters of
3666 buffer_defaults and buffer_local_symbols (for sanity and safety).
3668 2012-07-24 Eli Zaretskii <eliz@gnu.org>
3670 * xdisp.c (init_iterator): Don't compute dimensions of truncation
3671 and continuation glyphs on tooltip frames, leave them at zero.
3672 Avoids continued lines in tooltips. (Bug#11832)
3674 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

3683 or invalid. (Bug#12025)
3685 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
3686 it signals an error when a tooltip frame is being created.

3699 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3701 Swap buffer text indirection counters in Fbuffer_swap_text.
3702 * buffer.c (Fbuffer_swap_text): Swap indirections too.
3703 This avoids crash reported by Christoph Scholtes at
3704 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
3706 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
3708 * nsmenu.m (Popdown_data): New struct.

3713 and autorelease them. Also autorelease img and matrix (Bug#12005).
3714 (dealloc): Remove (Bug#12005).

3731 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
3733 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
3734 as it's limited by the amount of memory, not by INT_MAX.
3736 2012-07-21 Eli Zaretskii <eliz@gnu.org>
3738 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
3739 in special-event-map. See the discussion at

3889 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3891 * eval.c (Fdefvar): Don't check constants since we only set the var if
3892 it's not yet defined anyway (bug#11904).
3894 * lisp.h (last_undo_boundary): Declare new var.
3895 * keyboard.c (command_loop_1): Set it.
3896 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
3897 were auto-added by the command loop (bug#11774).

4465 This replaces macros (which typically do not work in GDB)
4466 with functions, typedefs and enums, making the code easier to debug.
4467 The functional style also makes code easier to read and maintain.
4468 * systime.h: Include <sys/time.h> on all hosts, not just if
4469 WINDOWSNT, since 'struct timeval' is needed in general.
4470 (EMACS_TIME): Now a typedef, not a macro.
4471 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
4473 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
4474 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
4475 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
4476 (EMACS_TIME_LE): Now functions, not macros.
4477 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
4478 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
4479 which are not functions. All uses rewritten to use:
4480 (make_emacs_time): New function.
4481 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
4482 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4483 not functions. All uses rewritten to use the following, respectively:
4484 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
4485 (add_emacs_time, sub_emacs_time): New functions.
4486 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
4487 * fileio.c (Fcopy_file):
4488 * xterm.c (XTflash): Get the current time closer to when it's used.
4489 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
4491 * bytecode.c (targets): Suppress -Woverride-init warnings.
4493 Simplify by avoiding confusing use of strncpy etc.
4494 * doc.c (Fsnarf_documentation):
4495 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
4496 * frame.c (Fmake_terminal_frame):
4497 * gtkutil.c (get_utf8_string):
4499 * nsmenu.m (ns_update_menubar):
4500 * regex.c (regerror):
4501 Prefer memcpy to strncpy and strncat when either will do.
4502 * fileio.c (Fsubstitute_in_file_name):
4503 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
4504 (menu_separator_name_p):
4505 * nsmenu.m (ns_update_menubar):
4506 Prefer memcmp to strncmp when either will do.
4507 * nsterm.m: Include <ftoastr.h>.
4509 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
4510 Prefer snprintf to strncpy.
4511 * nsterm.m (ns_term_init):
4512 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4513 * nsterm.m (ns_term_init):
4514 Avoid the need for strncpy, by using build_string or
4515 make_unibyte_string directly. Use dtoastr, not snprintf.
4516 * process.c (Fmake_network_process): Diagnose service names that
4517 are too long, rather than silently truncating them or creating
4518 non-null-terminated names.
4519 (Fnetwork_interface_info): Likewise, for interface names.
4520 * sysdep.c (system_process_attributes) [GNU_LINUX]:
4521 Prefer sprintf to strncat.
4522 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
4523 Prefer vsnprintf to vsprintf + strncpy.
4525 2012-07-10 Glenn Morris <rgm@gnu.org>
4527 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
4528 Clarify fallback case.
4530 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4532 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
4533 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
4534 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
4535 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
4536 where argument type is known to be a Lisp_Cons.
4538 2012-07-10 Tom Tromey <tromey@redhat.com>
4540 * bytecode.c (BYTE_CODE_THREADED): New macro.
4541 (BYTE_CODES): New macro. Replaces all old byte-code defines.
4542 (enum byte_code_op): New type.
4543 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
4544 (exec_byte_code): Use them. Use token threading when applicable.
4546 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4548 Optimize pure C strings initialization.
4549 * lisp.h (make_pure_string): Fix prototype.
4550 (build_pure_c_string): New function, defined as static inline. This
4551 provides a better opportunity to optimize away calls to strlen when
4552 the function is called with compile-time constant argument.
4553 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
4554 argument, adjust users accordingly. Use build_pure_c_string where
4556 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
4557 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
4558 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
4560 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4562 Avoid calls to strlen in miscellaneous functions.
4563 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
4564 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
4565 * lread.c (openp): Likewise.
4567 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4569 Avoid calls to strlen in path processing functions.
4570 * fileio.c (file_name_as_directory): Add comment. Change to add
4571 srclen argument and return the length of result. Adjust users
4573 (directory_file_name): Fix comment. Change to add srclen argument,
4574 swap 1st and 2nd arguments to obey the common convention.
4575 Adjust users accordingly.
4576 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
4578 2012-07-10 Glenn Morris <rgm@gnu.org>
4580 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
4581 Move PENDING_OUTPUT_COUNT definition to configure.
4583 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
4584 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
4585 * s/gnu.h (DATA_START): Move definitions to configure.
4587 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
4588 We include usg5-4-common.h, which defines them both.
4590 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
4591 O_RDONLY already includes it).
4593 Stop ns builds setting the EMACSLOADPATH environment variable.
4594 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4595 Now it does not set EMACSLOADPATH, just returns the load-path string.
4596 * nsterm.h: Update accordingly.
4597 * lread.c [HAVE_NS]: Include nsterm.h.
4598 (init_lread) [HAVE_NS]: Use ns_load_path.
4599 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
4601 2012-07-09 Glenn Morris <rgm@gnu.org>
4603 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
4604 since the included bsd-common.h does so.
4606 Stop ns builds setting the EMACSPATH environment variable.
4607 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
4608 (ns_init_paths): Do not set EMACSPATH.
4609 * nsterm.h (ns_exec_path): Add it.
4610 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
4613 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
4615 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
4617 * process.c (wait_reading_process_output): 'waitchannels' was unset
4618 when read_kbd || !NILP (wait_for_cell); fix this.
4620 Add GCC-style 'const' attribute to functions that can use it.
4621 * character.h (char_resolve_modifier_mask):
4622 * keyboard.h (make_ctrl_char):
4623 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
4624 (init_character_once, next_almost_prime, init_fns, init_image)
4625 (flush_pending_output, init_sound):
4626 * mem-limits.h (start_of_data):
4627 * menu.h (finish_menu_items):
4628 Add ATTRIBUTE_CONST.

4630 Declare the dummy function with ATTRIBUTE_CONST.
4631 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
4632 Add decls with ATTRIBUTE_CONST.
4634 Minor improvements to make_formatted_string.
4635 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
4636 where int is good enough, as vsprintf returns an int.
4637 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
4639 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4641 Use make_formatted_string to avoid double length calculation.
4642 * lisp.h (make_formatted_string): New prototype.
4643 * alloc.c (make_formatted_string): New function.
4644 * buffer.c (Fgenerate_new_buffer_name): Use it.
4645 * dbus.c (syms_of_dbusbind): Likewise.
4646 * editfns.c (Fcurrent_time_zone): Likewise.
4647 * filelock.c (get_boot_time): Likewise.
4648 * frame.c (make_terminal_frame, set_term_frame_name)
4649 (x_report_frame_params): Likewise.
4650 * image.c (gs_load): Likewise.
4651 * minibuf.c (get_minibuffer): Likewise.
4652 * msdos.c (dos_set_window_size): Likewise.
4653 * process.c (make_process): Likewise.

4657 2012-07-09 Glenn Morris <rgm@gnu.org>
4659 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
4660 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
4661 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
4662 * nsterm.h (ns_etc_directory): Add it.
4663 * callproc.c [HAVE_NS]: Include nsterm.h.
4664 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
4666 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4668 Move marker debugging code under MARKER_DEBUG.
4669 * marker.c (MARKER_DEBUG): Move marker debugging code under
4670 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4671 for bootstrap with --enable-checking (~3x slowdown reported
4672 by Juanma Barranquero <lekktu@gmail.com>).
4673 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4675 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4677 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
4678 See <http://bugs.gnu.org/11825#29>.
4680 2012-07-08 Eli Zaretskii <eliz@gnu.org>
4682 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4683 has no font, use the frame's font. (Bug#11813)
4684 (display_line): Add commentary about displaying truncation glyphs
4686 (produce_special_glyphs): Move here from term.c.
4688 * term.c (produce_special_glyphs): Move to xdisp.c.
4690 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4693 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4695 * xdisp.c (display_line): Avoid warning about implicit declaration
4698 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4700 * lisp.h: Remove empty conditional.
4702 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4704 * lread.c (load_path_check): Now static.
4706 Fix some minor --with-ns problems found by static checking.
4707 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
4708 (x_set_font) [!HAVE_X_WINDOWS]:
4709 * image.c (xpm_load_image) [HAVE_NS]:
4710 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4711 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4712 Remove unused local.
4713 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
4714 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
4715 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
4716 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
4717 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
4718 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
4719 Fix pointer signedness problem.
4720 * xfaces.c (FRAME_X_FONT_TABLE):
4721 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
4723 2012-07-07 Glenn Morris <rgm@gnu.org>
4725 * lread.c (load_path_check): New function, split from init_lread.
4726 (init_lread): Reorganize. Motivation:
4727 If EMACSLOADPATH is set, check/warn about that rather than the
4728 defaults, which we are not going to use. Hence we can remove
4729 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4730 Don't warn if site-lisp directories are missing.
4731 If not installed, start from a blank load-path, since
4732 PATH_LOADSEARCH refers to the eventual installation directories.
4734 2012-07-07 Eli Zaretskii <eliz@gnu.org>
4736 Support truncation and continuation glyphs on GUI frames, when
4737 fringes are disabled. (Bug#11832)
4738 * xdisp.c (init_iterator): Get dimensions of truncation and
4739 continuation glyphs even if on GUI frames.
4740 Adjust it->last_visible_x on GUI frames when the left or right fringes,
4741 or both, are absent.
4742 (start_display, move_it_in_display_line_to): Handle the case of a
4743 GUI frame without a fringe to display continuation or truncation
4745 (insert_left_trunc_glyphs): Support GUI frames: make sure
4746 truncation glyphs overwrite enough glyphs from the current line to
4747 have sufficient space in pixels.
4748 (display_line): Support truncation and continuation glyphs on GUI
4749 frames. If some spare pixels are left on the line after inserting
4750 the truncation glyphs, fill that space with a stretch glyph of a
4751 suitably computed width.
4753 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4754 produce_glyphs, to support GUI sessions.
4756 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4758 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4760 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4762 Do not require float-time's arg to fit in time_t (Bug#11825).
4763 This works better on hosts where time_t is unsigned, and where
4764 float-time is applied to the (negative) difference between two times.
4765 * editfns.c (decode_time_components): Last arg is now double *,
4766 not int *, and means to store all the result as a double, without
4767 worrying about whether the seconds part fits in time_t.
4768 All callers changed.
4769 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4770 All callers changed.
4771 (Ffloat_time): Do not fail merely because the specified time falls
4772 outside of time_t range.
4774 2012-07-07 Glenn Morris <rgm@gnu.org>
4776 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
4777 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
4778 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
4780 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
4782 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
4783 Update dependencies.
4785 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
4787 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4789 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
4790 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
4791 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
4792 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
4793 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
4794 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
4796 * xfont.c (compare_font_names): Redo to omit the need for casts.
4798 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4800 * xfns.c (Fx_change_window_property): Doc fix.
4801 * w32fns.c (Fx_change_window_property): Doc fix.
4803 * w32fns.c (Fx_window_property): Accept the same arguments as the
4804 X Windows version. Doc fix.
4805 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4807 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4808 Eli Zaretskii <eliz@gnu.org>
4810 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4811 Windows-specific code from nt/config.nt moved here.
4812 Obsolete settings removed.
4814 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4816 * process.c: Avoid unnecessary calls to gettime.
4817 (wait_reading_process_output): Don't get the time of day
4818 when gobbling data immediately and not waiting, as there's no need
4819 for it in that case. This removes a FIXME.
4821 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4823 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4824 is defined (Bug#11768).
4826 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4828 Fix marker debugging code.
4829 * marker.c (byte_char_debug_check): Do not perform the check
4830 if buffer is not multibyte.
4831 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4832 Call byte_char_debug_check with correct arguments.
4834 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4836 Compile marker debugging code only if ENABLE_CHECKING is defined.
4837 * marker.c (byte_char_debug_check, count_markers):
4838 Use only if ENABLE_CHECKING is defined.
4839 (byte_debug_flag): Remove.
4840 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4841 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4843 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4845 Avoid code repetition in marker-related functions.
4846 * marker.c (attach_marker): New function.
4847 (Fset_marker, set_marker_restricted, set_marker_both)
4848 (set_marker_restricted_both): Use it.
4849 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4850 Consistently rename charno to charpos.
4851 (marker_position): Add eassert.
4852 (marker_byte_position): Convert to eassert.
4854 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4856 Simplify list operations in unchain_overlay and unchain_marker.
4857 * buffer.c (unchain_overlay): Simplify. Add comment.
4858 * marker.c (unchain_marker): Simplify. Fix comments.
4860 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4862 Introduce fast path for the widely used marker operation.
4863 * alloc.c (build_marker): New function.

4869 (save_restriction_save): Use build_marker.
4870 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
4871 * window.c (save_window_save): Likewise.
4873 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4875 Do not use Fdelete_overlay in delete_all_overlays
4876 to avoid redundant calls to unchain_overlay.
4877 * buffer.c (drop_overlay): New function.
4878 (delete_all_overlays, Fdelete_overlay): Use it.
4879 * minibuf.c (get_minibuffer): Fix comment.
4881 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4883 Port to OpenBSD 5.1 amd64.
4884 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4885 This is needed for OpenBSD, and should be harmless on all BSD systems.
4886 Also, include <sys/sysctl.h>, as it should be available on all
4887 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4888 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4889 use p_pid member, not kp_proc.pid.
4891 2012-07-06 Glenn Morris <rgm@gnu.org>
4893 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4895 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4897 More xmalloc and related cleanup.
4898 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
4899 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

4906 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4908 Omit needless casts involving void * pointers and allocation.
4909 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4910 as the former is more robust if P's type is changed.
4911 Prefer xzalloc to xmalloc + memset 0.
4912 Simplify malloc-or-realloc to realloc.
4913 Don't worry about xmalloc returning a null pointer.
4914 Prefer xstrdup to xmalloc + strcpy.
4915 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4917 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4918 alloca of a constant.
4920 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4922 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4923 hscroll is larger than the line width. Fixes long and futile
4924 looping inside extend_face_to_end_of_line (on a TTY) producing
4925 glyphs that are not needed and thrown away.
4927 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

4939 not defined (Bug#11768).
4940 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
4941 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
4942 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
4943 followed by gtk_box_set_homogeneous (Bug#11768).
4944 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4945 (update_theme_scrollbar_width, xg_create_scroll_bar):
4946 Use gtk_scrollbar_new (Bug#11768).
4947 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

4955 * xdisp.c (window_hscroll_limited): New function.

5024 Problem reported by Troels Nielsen in
5025 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

5029 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
5030 This should be fixed in a better way; see Eli Zaretskii in
5031 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
5032 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
5034 * fileio.c (time_error_value): Rename from special_mtime.
5035 The old name's problems were noted by Eli Zaretskii in
5036 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
5038 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
5039 This variable's comment says Emacs needs at least one GDB-visible
5040 symbol of type enum pvec_type, to work around GDB problems.
5041 The symbol's value doesn't matter.
5043 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
5044 that causes compilation to fail on pre-C99 compilers.
5046 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
5048 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

5054 headers for buffer_defaults and buffer_local_symbols.
5055 Reported by Juanma Barranquero <lekktu@gmail.com>.
5057 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
5059 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
5060 * lisp.h (enum pvec_type): Use fewer bits.
5061 (PSEUDOVECTOR_SIZE_BITS): New constant.
5062 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
5063 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
5064 change in pvec_type.
5065 (PSEUDOVECTOR_TYPEP): New macro.

5071 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
5072 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
5073 (sweep_vectors): Use it. Use local var `total_bytes' instead of
5074 abusing vector->header.next.nbytes.
5075 (live_vector_p): Use PVEC_TYPE.
5076 (mark_object): Adapt code to extract pvectype. Use switch.
5078 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5080 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
5081 Tighten new eassert a bit.
5083 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5085 Fix compilation with --enable-gcc-warnings and -O1
5087 * doprnt.c (doprnt): Change type of tem to int, initialize
5088 to avoid compiler warning. Add eassert.
5089 * search.c (simple_search): Initialize match_byte to avoid
5090 compiler warning. Add eassert.
5092 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5094 Avoid weird behavior with large horizontal scrolls.
5095 Without this change, for example, large hscroll values would
5096 mess up Emacs's display on Fedora 15 x86, presumably due to
5097 overflows in int calculations in the display code.
5098 Also, if buffers had long lines, Emacs would freeze.
5099 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
5100 (set_window_hscroll): New function, containing the old guts of
5101 Fset_window_hscroll. Return the clipped value.
5102 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
5103 This avoids the need to check against PTRDIFF_MAX.
5105 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
5107 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5109 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
5111 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5113 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
5114 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
5115 since GCC 4.4.6 issues a bogus warning for them.
5117 Fix bugs in file timestamp newness comparisons.
5118 * fileio.c (Ffile_newer_than_file_p):
5119 * lread.c (Fload): Use full timestamp resolution of files,
5120 not just the 1-second resolution, so that files that are only
5121 slightly newer still count as newer.
5122 * fileio.c (Ffile_newer_than_file_p): Don't assume file
5123 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
5125 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
5127 * fileio.c: Improve handling of file time marker. (Bug#11852)
5128 (special_mtime): New function.
5129 (Finsert_file_contents, Fverify_visited_file_modtime):
5130 Use it to set special mtime values consistently.
5132 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
5134 * fileio.c (Finsert_file_contents): Properly handle st_mtime
5135 marker for non-existing file. (Bug#11852)
5137 2012-07-03 Glenn Morris <rgm@gnu.org>
5139 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
5140 and did not make it into globals.h).
5142 2012-07-03 Tom Tromey <tromey@redhat.com>
5144 * window.c (Fset_window_margins, Fset_window_fringes)

5178 * xterm.h: Remove EXFUN.
5180 2012-07-03 Glenn Morris <rgm@gnu.org>
5182 * lisp.h (Frandom): Make it visible to C.
5183 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
5184 buffer for invisible buffers. (Bug#1229)
5186 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5188 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
5189 values which aren't power of 2.
5190 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
5191 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
5194 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
5196 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
5198 * alloc.c (mark_object): Revert part of last patch to use `switch'.
5200 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5202 * alloc.c (allocate_vector_block): Remove redundant
5203 calls to mallopt if DOUG_LEA_MALLOC is defined.
5204 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
5205 avoid calls to mallopt if zero_vector is returned.
5207 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5209 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
5210 is enabled, avoid dereferencing NULL current_sblock if
5213 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5215 Cleanup basic buffer management.
5216 * buffer.h (struct buffer): Change layout to use generic vector
5217 marking code. Fix some comments. Change type of 'clip_changed'
5218 to bitfield. Remove unused #ifndef old.
5219 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
5220 (GET_OVERLAYS_AT): Fix indentation.
5221 (for_each_per_buffer_object_at): New macro.

5224 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
5225 * alloc.c (allocate_buffer): Adjust to match new layout of
5226 struct buffer. Fix comment.
5227 (mark_overlay): New function.

5229 Lisp area of struct buffer.
5230 (mark_object): Use it. Adjust marking of misc objects
5231 and related comments.
5233 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
5235 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
5236 wrapper that is not needed because the wrapped code is a no-op (zero
5237 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
5238 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
5240 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
5242 * alloc.c (mark_buffer): Simplify. Remove prototype.
5243 (mark_object): Add comment. Reorganize marking of vector-like
5244 objects. Use CHECK_LIVE for all vector-like objects except buffers
5245 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
5246 Avoid redundant calls to mark_vectorlike for bool vectors.
5248 2012-06-30 Glenn Morris <rgm@gnu.org>
5250 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
5252 * epaths.in (PATH_SITELOADSEARCH): New.
5253 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
5254 This is rather than relying on --enable-locallisppath elements
5255 having "site-lisp" in their names. (Bug#10208#25, 11658)
5257 2012-06-30 Eli Zaretskii <eliz@gnu.org>
5259 * w32proc.c (sys_select): Accept and ignore one more argument.
5261 * w32.c (emacs_gnutls_pull): Call select with one more argument.
5263 * sysselect.h [DOS_NT]: Don't include sys/select.h.
5264 (pselect) [!MS_DOS]: Redirect to sys_select.
5266 * sysdep.c: Don't include dos.h and dosfns.h.
5268 * process.c (sys_select):
5269 * msdos.c (sys_select): Accept one more argument and ignore it.
5271 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
5272 adapt data types and code to that.
5275 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
5276 which clashes with the gnulib function of the same name.
5278 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
5280 * font.c (font_style_to_value, font_style_symbolic)
5281 (font_prop_validate_style): Add type checks for values in
5284 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
5286 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
5289 2012-06-29 Eli Zaretskii <eliz@gnu.org>
5291 * xdisp.c (try_window_id): Undo last change.
5293 * w32.c (getwd): Adjust commentary about startup_dir.
5294 (init_environment): Always call sys_access, even in non-MSVC
5295 builds. Don't chdir to the directory of the Emacs executable.
5296 This undoes code from 1997 which was justified by the need to
5297 "avoid conflicts when removing and renaming directories". But its
5298 downside was that every relative file name was being interpreted
5299 relative to the directory of the Emacs executable, which can never
5300 be TRT. In particular, it broke sys_access when called with
5301 relative file names.
5302 (sys_access): Map GetLastError to errno.
5304 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5306 * window.h (struct window): Change type of 'fringes_outside_margins'

5310 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
5313 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
5315 * gnutls.c (emacs_gnutls_handshake):
5316 Add QUIT to make the loop interruptible.
5318 2012-06-29 Glenn Morris <rgm@gnu.org>
5320 * charset.c (init_charset): Make lack of etc/charsets fatal.
5322 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5324 * editfns.c (region_limit): Fix type mismatch.
5326 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5328 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
5329 undefined. Convert from xassert to eassert.
5330 * nsmenu.m: Convert from xassert to eassert.
5331 * nsterm.m: Likewise.
5333 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
5335 * editfns.c (region_limit): Clip to narrowing (bug#11770).
5337 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
5339 Avoid integer overflow on scroll-left and scroll-right.
5340 * window.c (HSCROLL_MAX): New macro.
5341 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
5342 overflow when requested scroll falls outside ptrdiff_t range.
5344 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
5346 * window.h (struct window): Change type of 'hscroll',
5347 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
5348 'last_modified' and 'last_overlay_modified' to EMACS_INT.
5349 Adjust users accordingly.
5350 * xdisp.c (try_cursor_movement): Replace type check with eassert.
5351 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
5352 from EMACS_INT to ptrdiff_t.
5353 (make_window): Omit redundant initialization.
5355 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
5357 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
5359 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
5361 * window.h (struct window): Change type of 'use_time' and
5362 'sequence_number' from Lisp_Object to int.
5363 * frame.c (make_frame): Adjust users accordingly.
5364 * print.c (print_object): Likewise.
5365 * window.c (select_window, Fwindow_use_time, make_parent_window)
5366 (make_window): Likewise.
5368 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
5370 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
5371 enabled with --enable-checking=[all,glyphs] configure option.
5372 Fix GLYPH_DEBUG usage assuming that it may be undefined,
5373 adjust comments accordingly.
5374 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
5375 undefined, adjust comments accordingly.

5496 Use sprintf return value instead of invoking strlen on result.
5497 In the old days this wasn't portable, since some sprintf
5498 implementations returned char *. But they died out years ago and
5499 Emacs already assumes sprintf returns int.
5500 Similarly for float_to_string.
5501 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

5509 Use sprintf or float_to_string result to avoid need to call strlen.
5510 * data.c (Fnumber_to_string):
5511 Use make_unibyte_string, since the string must be ASCII.
5512 * lisp.h, print.c (float_to_string): Now returns int length.
5513 * term.c (produce_glyphless_glyph):
5514 Use sprintf result rather than recomputing it.
5516 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
5517 * Makefile.in (ALL_CFLAGS):

5547 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
5549 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

5552 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
5554 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
5555 instead of truncating it to 63 (admittedly a generous limit).

5615 * keyboard.c (kbd_buffer_get_event):
5616 * process.c (Faccept_process_output):
5617 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
5618 This improves on the previous patch, which introduced a bug
5619 when time_t is unsigned and as wide as intmax_t.
5620 See <http://bugs.gnu.org/9000#51>.
5622 2012-06-23 Eli Zaretskii <eliz@gnu.org>

5685 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5687 Support higher-resolution time stamps (Bug#9000).
5688 The time stamps are only nanosecond-resolution at the C level,
5689 since that's the best that any real-world system supports now.
5690 But they are picosecond-resolution at the Lisp level, as that's
5691 easy, and leaves room for future OS improvements.
5693 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5696 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5697 Don't get current time unless it's needed.
5699 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5700 now provides it if it's absent.
5701 (start_atimer): Port to higher-res time stamps.
5702 Check for time stamp overflow. Don't get current time more
5703 often than is needed.
5705 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5706 Include systime.h, not time.h.
5707 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
5709 * dired.c: Include stat-time.h.
5710 (Ffile-attributes): File times now have higher resolution.
5712 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
5713 (struct image): Timestamp now has higher resolution.
5715 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5716 has at least microseconds now. All uses removed.
5717 (update_frame, update_single_window, update_window, update_frame_1)
5718 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5719 (duration_to_sec_usec): Remove; no longer needed.
5721 * editfns.c (time_overflow): Now extern.
5722 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
5723 (float-time, Fformat_time_string, Fcurrent_time_string)

5727 (decode_time_components, lisp_seconds_argument): New functions.
5728 (make_time): Now static.
5729 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
5730 Report an error if the time is invalid, rather than having the caller
5733 * fileio.c: Include <stat-time.h>
5734 (Fcopy_file): Copy higher-resolution time stamps.
5735 Prefer to set the time stamp via a file descriptor if that works.
5736 (Fset_file_times, Finsert_file_contents, Fwrite_region)
5737 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
5738 (Fvisited_file_modtime, Fset_visited_file_modtime):
5739 Support higher-resolution time stamps.
5741 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
5743 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
5745 * image.c (prepare_image_for_display, clear_image_cache)
5746 (lookup_image): Port to higer-resolution time stamps.
5748 * keyboard.c (start_polling, bind_polling_period):
5749 Check for time stamp overflow.
5750 (read_char, kbd_buffer_get_event, timer_start_idle)
5751 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
5752 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5753 Port to higher-resolution time stamps. Do not assume time_t is signed.
5754 (decode_timer): New function. Timers are now vectors of length 9,
5755 not 8, to accommodate the picosecond component.
5756 (timer_check_2): Use it.
5758 * nsterm.m (select_timeout, timeval_subtract): Remove.
5759 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5760 as they're a bit more accurate and handle overflow better.
5761 (ns_select): Change prototype to be compatible with pselect.
5762 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5763 * nsterm.h (ns_select): Adjust prototype.
5765 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5766 us-resolution time stamps.
5767 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5769 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5771 * lisp.h (time_overflow): New decl.
5772 (wait_reading_process_output): First arg is now intmax_t, not int,
5773 to accommodate larger waits.
5775 * process.h (struct Lisp_Process.read_output_delay):
5776 Now counts nanoseconds, not microseconds.
5777 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
5779 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
5780 (wait_reading_process_output):
5781 Port to ns-resolution time stamps.
5782 (Faccept_process_output, wait_reading_process_output):
5783 Check for time stamp overflow. Do not assume time_t is signed.
5784 (select_wrapper): Remove; we now use pselect.
5785 (Fprocess_attributes): Now generates ns-resolution time stamps.
5787 * sysdep.c: Include utimens.h. Don't include utime.h
5788 or worry about struct utimbuf; gnulib does that for us now.
5789 (gettimeofday): Remove; gnulib provides a substitute.
5790 (make_timeval): New function.
5791 (set_file_times): Now sets ns-resolution time stamps.
5792 New arg FD; all uses changed.
5793 (time_from_jiffies, ltime_from_jiffies, get_up_time)
5794 (system_process_attributes):
5795 Now returns ns-resolution time stamp. All uses changed.
5796 Check for time stamp overflow.
5798 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5799 provides a substitute now.
5801 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5802 since it guarantees struct timespec.
5803 (EMACS_TIME): Now struct timespec, so that we can support
5804 ns-resolution time stamps.
5805 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5806 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5807 (EMACS_USECS): Remove.
5808 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5809 so multiply the arg by 1000 before storing it.
5810 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
5812 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
5813 Port to ns-resolution time stamps.
5814 (EMACS_TIME_NEG_P): Remove; replaced by....
5815 (EMACS_TIME_SIGN): New macro.
5816 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
5817 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
5818 (set_file_times, make_time, lisp_time_argument): Adjust signature.
5819 (make_timeval, make_lisp_time, decode_time_components): New decls.
5820 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
5821 that it mishandled time_t overflow. You can't compare by subtracting!
5822 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
5823 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
5825 * term.c: Include <sys/time.h>.
5826 (timeval_to_Time): New function, for proper overflow wraparound.
5827 (term_mouse_position, term_mouse_click): Use it.
5829 * undo.c (record_first_change): Support higher-resolution time stamps
5831 (Fprimitive_undo): Use them when restoring time stamps.
5833 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
5834 (w32_get_internal_run_time):
5835 Port to higher-resolution Emacs time stamps.
5836 (ltime): Now accepts single 64-bit integer, as that's more convenient
5839 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
5841 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
5842 for compatibility with pselect. Support ns-resolution time stamps.
5844 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
5846 * xselect.c (wait_for_property_change, x_get_foreign_selection):
5847 Check for time stamp overflow, and support ns-resolution time stamps.
5849 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
5850 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
5851 (timeval_subtract): Remove; no longer needed.
5852 (XTflash, XTring_bell, x_wait_for_event):
5853 Port to ns-resolution time stamps. Don't assume time_t is signed.
5855 2012-06-22 Chong Yidong <cyd@gnu.org>
5857 * xdisp.c (x_consider_frame_title): Revert last change.
5859 2012-06-22 Eli Zaretskii <eliz@gnu.org>
5861 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled

6137 as the union type is for debugging, not for production.
6138 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
6139 Use an inline function on all platforms when using the union type,
6140 since this is simpler and 'static inline' can be used portably

6284 * doprnt.c (doprnt): Truncate multibyte char correctly.
6285 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
6286 would mishandle a string argument "Xc" if X was a multibyte
6287 character of length 2: it would truncate after X's first byte
6288 rather than including all of X.

6339 * minibuf.c (Fassoc_string): Remove duplicate declaration.
6341 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
6342 Convert pctcpu and pctmem to Lisp float properly.
6343 Let the compiler fold better, as 100.0/0x8000 is exact.
6345 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
6347 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
6350 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
6352 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
6354 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
6356 For a 'struct window', replace some Lisp_Object fields to
6357 bitfields where appropriate, remove unused fields.
6358 * window.h (struct window): Remove unused 'last_mark_x' and
6359 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
6360 change it's type from Lisp_Object to bitfield.
6361 Change type of 'force_start', 'optional_new_start',
6362 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
6363 fields from Lisp_Object to bitfield. Adjust users accordingly.
6365 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6367 Pacify gcc -Wdouble-precision when using Xaw.
6368 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
6369 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
6370 Use 'float' consistently, rather than 'float' in most places
6371 and 'double' in a couple of places.
6373 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6375 * xdisp.c (handle_stop): Detect whether we have overlay strings
6376 loaded by testing it->current.overlay_string_index to be
6377 non-negative, instead of checking whether n_overlay_strings is
6378 positive. (Bug#11587)
6380 2012-05-31 Chong Yidong <cyd@gnu.org>
6382 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
6384 * doc.c (Fsubstitute_command_keys): Doc fix.
6386 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6388 * search.c (search_buffer): Remove calls to
6389 r_alloc_inhibit_buffer_relocation, as it is now called by
6390 maybe_unify_char, which was the cause of relocation of buffer text
6393 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6395 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6396 for the duration of call to load_charset, to avoid problems with
6397 callers of maybe_unify_char that access buffer text through C
6400 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6401 decrement the inhibition flag, instead of just setting or
6404 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6406 Remove obsolete '#define static' cruft.
6407 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6408 This #undef was "temporary" in 2000; it is no longer needed
6409 now that '#define static' has gone away.
6410 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6411 (gray_bitmap_bits): Remove; no longer needed.
6412 All uses replaced with definiens.
6413 * xterm.c: Include "bitmaps/gray.xbm".
6415 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6417 Clean up __executable_start, monstartup when --enable-profiling.
6418 The following changes affect the code only when profiling.
6419 * dispnew.c (__executable_start): Rename from safe_bcopy.
6420 Define only on platforms that need it.
6421 * emacs.c: Include <sys/gmon.h> when profiling.
6422 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6423 (__executable_start): Remove decl, since lisp.h does it now.
6424 (safe_bcopy): Remove decl; no longer has that name.
6425 (main): Coalesce #if into single bit of code, for simplicity.
6426 Cast pointers to uintptr_t, since standard libraries want integers
6428 * lisp.h (__executable_start): New decl.
6430 2012-05-31 Glenn Morris <rgm@gnu.org>
6432 * image.c (Fimagemagick_types): Doc fix.
6434 2012-05-30 Jim Meyering <meyering@redhat.com>
6436 * callproc.c (Fcall_process_region): Include directory component
6437 in mkstemp error message (Bug#11586).
6439 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6441 * alloc.c, lisp.h (make_pure_vector): Now static.
6443 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

6448 * data.c (Fdefalias): Purify definition, except for keymaps.
6449 (Qdefun): Move from eval.c.
6450 * lisp.h (Qdefun): Remove.
6451 * lread.c (read1): Tiny simplification.
6453 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
6455 Do not create empty overlays with the evaporate property (Bug#9642).
6456 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6457 Bug#9642, but explicitly check that the buffer the overlay would
6458 be moved to is live and rearrange lines to make sure that errors
6459 will not put the overlay in an inconsistent state.
6460 (Fdelete_overlay): Cosmetics.
6462 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6464 * w32term.c (my_bring_window_to_top): New function.
6465 (x_raise_frame): Use handle returned by DeferWindowPos, which
6466 could be different from the original one.
6467 Call my_bring_window_to_top instead of my_set_foreground_window.
6470 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6471 by calling BringWindowToTop.
6473 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6474 (WM_EMACS_END): Increase by one.
6476 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6478 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6479 This avoids undefined behavior that might cause the eassert
6480 to not catch an out-of-range value.
6482 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6484 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
6485 Update dependencies.
6487 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6489 * bidi.c (bidi_mirror_char): Fix last change.
6491 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
6493 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
6494 when referring to sectname field in printf format.
6496 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
6498 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6499 Only r_alloc_inhibit_buffer_relocation needed to be added;
6500 the others were already declared.
6502 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6503 before checking whether it's out of range. Put the check inside
6505 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6507 2012-05-27 Ken Brown <kbrown@cornell.edu>
6509 * callproc.c (Fcall_process): Restore a line that was accidentally
6510 commented out in the 2011-02-13 change (bug#11547).
6512 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6514 * lisp.h [REL_ALLOC]: Add prototypes for external functions
6515 defined on ralloc.c.
6517 * buffer.c [REL_ALLOC]: Remove prototypes of
6518 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
6519 they are now on lisp.h.
6521 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6523 * search.c (search_buffer): Use it to inhibit relocation of buffer
6524 text while re_search_2 is doing its job, because re_search_2 is
6525 passed C pointers to buffer text. (Bug#11519)
6527 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6530 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6531 state after an additional call to move_it_in_display_line_to, keep
6532 the values of it->max_ascent and it->max_descent found for the
6534 (pos_visible_p): Revert the comparison against bottom_y to what it
6535 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
6538 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6540 Fix coding-related core dumps with gcc -ftrapv.
6541 The code was computing A - B, where A and B are pointers, and B is
6542 random garbage. This can lead to core dumps on platforms that
6543 have special pointer registers, and it also leads to core dumps on
6544 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6545 A - B only when B is initialized properly.
6546 * coding.c (coding_set_source, coding_set_destination): Return void.
6547 (coding_change_source, coding_change_destinations): New functions,
6548 with the old behaviors of coding_set_source and coding_set_destination.
6549 All callers that need an offset changed to use these new functions.
6551 2012-05-26 Glenn Morris <rgm@gnu.org>
6553 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
6555 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6557 Extend mouse support on W32 text-mode console.
6558 * xdisp.c (draw_row_with_mouse_face):
6559 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6561 * w32console.c: Include window.h.
6562 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6564 (initialize_w32_display): Initialize mouse-highlight data.
6566 * w32inevt.c: Include termchar.h and window.h.
6567 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6568 moves, call note_mouse_highlight. If help_echo changed, call
6569 gen_help_event to produce help-echo message in the echo area.
6570 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6573 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6575 * lread.c (read1): Simplify slightly to avoid an overflow warning
6576 with GCC 4.7.0 on x86-64.
6578 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6580 * bidi.c (bidi_mirror_char): Revert last change: an int is
6581 definitely wide enough here.
6583 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
6585 Fix integer width and related bugs (Bug#9874).
6586 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
6587 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
6588 (string_bytes, check_sblock, allocate_string_data):
6589 (compact_small_strings, Fmake_bool_vector, make_string)
6590 (make_unibyte_string, make_multibyte_string)
6591 (make_string_from_bytes, make_specified_string)
6592 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
6593 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
6595 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6596 (allocate_pseudovector):
6597 Use int, not EMACS_INT, where int is wide enough.
6598 (inhibit_garbage_collection, Fgarbage_collect):
6599 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6600 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
6601 int might not be wide enough.
6602 (bidi_cache_search, bidi_cache_find, bidi_init_it)
6603 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6604 (bidi_at_paragraph_end, bidi_find_paragraph_start)
6605 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
6606 (bidi_level_of_next_char, bidi_move_to_visually_next):
6607 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6608 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
6609 (Fkill_buffer, Fset_buffer_major_mode)
6610 (advance_to_char_boundary, Fbuffer_swap_text)
6611 (Fset_buffer_multibyte, overlays_at, overlays_in)
6612 (overlay_touches_p, struct sortvec, record_overlay_string)
6613 (overlay_strings, recenter_overlay_lists)
6614 (adjust_overlays_for_insert, adjust_overlays_for_delete)
6615 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
6616 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
6617 (Foverlay_recenter, last_overlay_modification_hooks_used)
6618 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6619 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6620 (validate_region): Omit unnecessary test for b <= e,
6621 since that's guaranteed by the previous test.
6622 (adjust_overlays_for_delete): Avoid pos + length overflow.
6623 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6624 (report_overlay_modification):
6625 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6626 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
6627 Omit pointer cast, which isn't needed anyway, and doesn't work
6628 after the EMACS_INT -> ptrdiff_t change.
6629 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
6630 * buffer.h: Adjust decls to match defn changes elsewhere.
6631 (struct buffer_text, struct buffer):
6632 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6633 Use EMACS_INT, not int, where int might not be wide enough.
6634 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
6635 not int, to avoid needless 32-bit limit on 64-bit hosts.
6636 (exec_byte_code): Use tighter memory-full test, one that checks
6637 for alloca overflow. Don't compute the address of the object just
6638 before an array, as that's not portable. Use EMACS_INT, not
6639 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
6640 * callint.c (Fcall_interactively):
6641 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6642 * callproc.c (call_process_kill, Fcall_process):
6643 Don't assume pid_t fits into an Emacs fixnum.
6644 (call_process_cleanup, Fcall_process, child_setup):
6645 Don't assume pid_t fits into int.
6646 (call_process_cleanup, Fcall_process, delete_temp_file)
6647 (Fcall_process_region):
6648 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6649 (Fcall_process): Simplify handling of volatile integers.
6650 Use int, not EMACS_INT, where int will do.
6651 * casefiddle.c (casify_object, casify_region, operate_on_word)
6652 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
6653 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6654 (casify_object): Avoid integer overflow when overallocating buffer.
6655 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
6656 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
6657 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
6658 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6659 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6660 integers are now checked earlier. All uses replaced with XINT.
6662 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6663 For CCL_MapSingle, check that content and value are in int range.
6664 (ccl_driver, Fregister_code_conversion_map):
6665 Check that Vcode_version_map_vector is a vector.
6666 (resolve_symbol_ccl_program): Check that vector header is in range.
6667 Always copy the vector, so that we can check its contents reliably
6668 now rather than having to recheck each instruction as it's being
6669 executed. Check that vector words fit in 'int'.
6670 (ccl_get_compiled_code, Fregister_ccl_program)
6671 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6672 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
6673 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
6674 contents are in range.
6675 (Fccl_execute_on_string): Check that status is in range.
6676 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
6677 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
6678 Accept and return EMACS_INT, not int, because callers can pass values
6680 (c_string_width, strwidth, lisp_string_width, chars_in_text)
6681 (multibyte_chars_in_text, parse_str_as_multibyte)
6682 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
6683 (str_as_unibyte, str_to_unibyte, string_count_byte8)
6684 (string_escape_byte8, Fget_byte):
6685 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6686 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
6687 avoid mishandling large integers.
6688 * character.h: Adjust decls to match defn changes elsewhere.
6689 * charset.c (load_charset_map_from_file, find_charsets_in_text)
6690 (Ffind_charset_region):
6691 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6692 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
6693 (load_charset_map_from_vector, Fdefine_charset_internal):
6694 Don't assume fixnum fits in int.
6695 (load_charset_map_from_vector, Fmap_charset_chars):
6696 Remove now-unnecessary CHECK_NATNUMs.
6697 (Fdefine_charset_internal): Check ranges here, more carefully.
6698 Don't rely on undefined behavior with signed left shift overflow.
6699 Don't assume unsigned int fits into fixnum, or that fixnum fits
6700 into unsigned int. Don't require max_code to be a valid fixnum;
6701 that's not true for gb10830 4-byte on a 32-bit host. Allow
6702 invalid_code to be a cons, for the same reason. Require code_offset
6703 to be a character. Avoid int overflow if max_char is close
6705 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
6706 this is intended anyway and avoids some undefined behavior.
6707 (load_charset_map): Pass unsigned, not int, as 2nd arg of
6708 INDEX_TO_CODE_POINT, as that's what it expects.
6709 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
6710 * charset.h (DECODE_CHAR): Return int, not unsigned;
6711 this is what was intended anyway, and it avoids undefined behavior.
6712 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
6713 integer-overflow issues.
6714 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
6715 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
6716 where the argument is EMACS_INT, and this behavior is not intended.
6717 * chartab.c (Fmake_char_table, Fset_char_table_range)
6718 (uniprop_get_decoder, uniprop_get_encoder):
6719 Don't assume fixnum fits in int.
6720 * cmds.c (move_point): New function, that does the gist of
6721 Fforward_char and Fbackward_char, but does so while checking
6722 for integer overflow more accurately.
6723 (Fforward_char, Fbackward_char): Use it.
6724 (Fforward_line, Fend_of_line, internal_self_insert)
6725 (internal_self_insert):
6726 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6727 Fix a FIXME, by checking for integer overflow when calculating
6728 target_clm and actual_clm.
6729 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)

7476 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
7478 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
7479 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
7481 2012-05-18 Eli Zaretskii <eliz@gnu.org>
7483 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
7485 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
7486 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
7488 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
7489 reference to image_cache->refcount.
7490 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
7492 2012-05-17 Juri Linkov <juri@jurta.org>
7494 * search.c (Fword_search_regexp, Fword_search_backward)
7495 (Fword_search_forward, Fword_search_backward_lax)
7496 (Fword_search_forward_lax): Move functions to isearch.el
7497 (bug#10145, bug#11381).
7499 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
7501 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
7503 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
7505 * lread.c (init_obarray): Declare Qt and Qnil as special.
7507 2012-05-14 Glenn Morris <rgm@gnu.org>
7509 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
7510 Put "libexec" before "bin", for the sake of init_callproc_1.
7512 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7514 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
7516 * unexaix.c: Port to more-recent AIX compilers.
7517 (report_error, report_error_1, make_hdr, copy_sym)
7518 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
7519 Make arguments const char *, not char *, to avoid violations of C
7520 standard and to fix some AIX warnings reported by Gilles Pion.
7522 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7524 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
7525 already have overlays loaded.
7526 (handle_single_display_spec): Before returning without displaying
7527 fringe bitmap, synchronize the bidi iterator with the main display
7528 iterator, by calling iterate_out_of_display_property.
7529 (iterate_out_of_display_property): Detect buffer iteration by
7530 testing that it->string is a Lisp string.
7531 (get_next_display_element): When the current object is exhausted,
7532 and there's something on it->stack, call set_iterator_to_next to
7533 proceed with what's on the stack, instead of returning zero.
7534 (set_iterator_to_next): If called at the end of a Lisp string,
7535 proceed to consider_string_end without incrementing string
7536 position. Don't increment display vector index past the end of
7537 the display vector. (Bug#11417)
7538 (pos_visible_p): Don't report a position visible when move_it_to
7539 stopped at the last line of window, which happens to be scanned
7540 backwards by the bidi iteration. (Bug#11464)
7542 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7544 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7545 and right-margin display specs even if the spec is invalid or we
7546 are on a TTY, and thus unable to display on the fringes.
7547 That's because the text with the property will not be displayed anyway,
7548 so we need to signal to the caller that this is a "replacing"
7549 display spec. This fixes display when the spec is invalid or we
7552 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7554 * unexaix.c (make_hdr): Fix typo in prototype.
7555 This bug broke the build on AIX. Problem reported by Gilles Pion.
7557 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
7559 * keyboard.c (kbd_buffer_get_event): Read special events also in
7560 batch mode. (Bug#11415)
7562 2012-05-12 Glenn Morris <rgm@gnu.org>
7564 * ns.mk: Update for ns_appbindir no longer having trailing "/".
7566 2012-05-12 Eli Zaretskii <eliz@gnu.org>
7568 * lisp.mk (lisp): Add newcomment.elc.
7570 2012-05-12 Glenn Morris <rgm@gnu.org>
7572 * Makefile.in (MKDIR_P): New, set by configure.
7573 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
7575 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
7577 Remove unused function hourglass_started.
7578 * dispextern.h (hourglass_started):
7579 * w32fns.c (hourglass_started):
7580 * xdisp.c (hourglass_started): Remove.
7582 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7584 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7585 Update dependencies.
7587 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7589 * xgselect.c (xg_select): Put maxfds+1 into a var.
7590 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
7592 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7594 2012-05-10 Dave Abrahams <dave@boostpro.com>
7596 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7597 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7599 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7601 * dbusbind.c (xd_registered_buses): New internal Lisp object.
7602 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7603 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7604 Initialize xd_registered_buses.
7606 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7608 Untag more efficiently if USE_LSB_TAG.
7609 This is based on a proposal by YAMAMOTO Mitsuharu in
7610 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7611 For an admittedly artificial (nth 8000 longlist) benchmark on
7612 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7613 Emacs's overall text size by 1%.
7614 * lisp.h (XUNTAG): New macro.
7615 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7616 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7617 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7618 * eval.c (Fautoload):
7619 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7620 * frame.h (XFRAME): Use XUNTAG.
7622 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7623 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7624 Remove unportable assumptions about print widths of types like
7626 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7627 intptr_t when converting between pointer and integer, to avoid GCC
7628 warnings about wrong width.
7630 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7632 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7633 stack for each reader_thread, instead of defaulting to 8MB
7634 determined by the linker. This avoids failures in creating
7635 subprocesses on Windows 7, see the discussion in this thread:
7636 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7638 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7640 Fix up display of the *Minibuf-0* buffer in the mini window.
7641 * keyboard.c (read_char): Don't clear the echo area if there's no
7643 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7644 contents of *Minibuf-0*) if there's no message displayed in its stead.
7646 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7648 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7651 2012-05-06 Chong Yidong <cyd@gnu.org>
7653 * lisp.mk (lisp): Update.
7655 2012-05-05 Jim Meyering <meyering@redhat.com>
7657 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7659 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7661 * data.c (PUT_ERROR): New macro.
7662 (syms_of_data): Use it. Add new error type `user-error'.
7663 * undo.c (user_error): New function.
7664 (Fprimitive_undo): Use it.
7665 * print.c (print_error_message): Adjust print style for `user-error'.
7666 * keyboard.c (user_error): New function.
7667 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7669 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7671 Do not limit current-time-string to years 1000..9999.
7672 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7673 (Fcurrent_time_string): Support any year that is supported by the
7674 underlying localtime representation. Don't use asctime, as it
7675 has undefined behavior for years outside the range -999..9999.
7677 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7679 Fix race conditions involving setenv, gmtime, localtime, asctime.
7680 Without this fix, interrupts could mess up code that uses these
7681 nonreentrant functions, since setting TZ invalidates existing
7682 tm_zone or tzname values, and since most of these functions return
7683 pointers to static storage.
7684 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7685 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7686 Grow the critical sections to include not just invoking
7687 localtime/gmtime, but also accessing these functions' results
7688 including their tm_zone values if any, and any related TZ setting.
7689 (format_time_string): Last arg is now struct tm *, not struct tm **,
7690 so that the struct tm is saved in the critical section.
7691 All callers changed. Simplify allocation of initial buffer, partly
7692 motivated by the fact that memory allocation needs to be outside
7693 the critical section.
7695 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7697 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7698 with RESET_INTERVAL.
7700 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7701 Remove duplicated buffer name initialization.
7703 2012-05-02 Jim Meyering <jim@meyering.net>
7705 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7707 * xfns.c (x_window): Use xstrdup (Bug#11375).
7709 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7711 * xdisp.c (pos_visible_p): If already at a newline from the
7712 display string before the 'while' loop, don't walk back the glyphs
7713 from it3.glyph_row. Solves assertion violation when the display
7714 string begins with a newline (egg.el). (Bug#11367)
7716 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7718 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7721 2012-05-01 Glenn Morris <rgm@gnu.org>
7723 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7724 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7725 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7726 All were removed before 23.1.
7728 * dispnew.c: Remove HAVE_LIBNCURSES test;
7729 it is always true on relevant platforms.
7731 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7732 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7734 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
7736 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
7738 * .gdbinit (xpr): Remove checks for no longer existing misc types.
7739 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
7742 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
7744 Do not avoid creating empty evaporating overlays (Bug#9642).
7745 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7746 That is, do not delete an evaporating overlay if it becomes
7747 empty after its bounds are adjusted to fit within its buffer.
7748 This fix caused other problems, and I'm reverting it until we get
7749 to the bottom of them.
7751 2012-04-27 Chong Yidong <cyd@gnu.org>
7753 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7755 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7757 * xdisp.c (pos_visible_p): If the window start position is beyond
7758 ZV, start the display from buffer beginning. Prevents assertion
7759 violation in init_iterator when the minibuffer window is scrolled
7762 * window.c (window_scroll_pixel_based): Likewise.
7764 2012-04-27 Chong Yidong <cyd@gnu.org>
7766 * keymap.c (where_is_internal): Doc fix (Bug#10872).
7768 2012-04-27 Glenn Morris <rgm@gnu.org>
7770 * fileio.c (Fcopy_file, Fset_file_selinux_context):
7771 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
7773 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7775 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
7776 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
7778 2012-04-26 Eli Zaretskii <eliz@gnu.org>
7780 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7781 display element, check also the underlying string or buffer
7782 character. (Bug#11341)
7784 * w32menu.c: Include w32heap.h.
7785 (add_menu_item): If the call to AppendMenuW (via
7786 unicode_append_menu) fails, disable Unicode menus only if we are
7787 running on Windows 9X/Me.
7789 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7791 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
7792 (xgetint): Add missing shift for LSB tags.
7794 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7796 * keyboard.c (read_char): Don't wipe echo area for select window
7797 events: These might get delayed via `mouse-autoselect-window'
7800 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
7802 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
7803 manipulation of :loaded-from data.
7805 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
7807 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
7808 now a cons (bug#11311).
7810 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7812 Do not create empty overlays with the evaporate property (Bug#9642).
7813 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7814 if it becomes empty after its bounds are adjusted to fit within
7815 its buffer. Without this fix, in a nonempty buffer (let ((o
7816 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7817 yields an empty overlay that has the evaporate property, which is
7818 not supposed to happen.
7820 Fix minor GTK3 problems found by static checking.
7821 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7822 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7823 (struct _EmacsFixedClass, emacs_fixed_get_type):
7824 Move decls here from emacsgtkfixed.h, since they needn't be public.
7825 (emacs_fixed_get_type): Now static.
7826 (emacs_fixed_class_init): Omit unused local.
7827 (emacs_fixed_child_type): Remove; unused.

7829 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7830 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
7831 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
7832 (EMACS_FIXED_GET_CLASS): Remove; unused.
7833 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
7835 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
7836 Problem reported by Juanma Barranquero for Windows -Wunused-function.
7838 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7840 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
7841 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
7842 (__malloc_size_t, __malloc_ptrdiff_t):
7843 Remove. All uses removed, replaced by the definiens if needed,
7844 since we can assume C89 or better now.
7845 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
7846 (protect_malloc_state, align, get_contiguous_space)
7847 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

7853 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
7854 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
7855 Define using prototypes, not old style.
7856 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
7857 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
7858 (align): Don't assume that signed integer overflow wraps around.
7859 Omit unused local var.
7860 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
7861 (_free_internal_nolock, memalign, mallochook, reallochook):
7862 Omit no-longer-needed casts.
7863 (valloc): Use getpagesize, not __getpagesize.
7864 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
7865 (struct hdr): The 'magic' member is now size_t, not unsigned long.
7867 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
7869 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
7871 Move functions from C to Lisp. Make non-blocking method calls
7872 the default. Implement further D-Bus standard interfaces.
7874 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
7875 (QCdbus_request_name_allow_replacement)
7876 (QCdbus_request_name_replace_existing)

7914 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7916 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
7917 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
7918 Do not assume ptrdiff_t is the same width as 'int'.
7920 * alloc.c: Handle unusual debugging option combinations.
7921 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
7922 since the two debugging options are incompatible.
7923 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7925 (mem_init, mem_insert, mem_insert_fixup):
7926 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

7958 (print_object): Check for cycles even when print-circle is nil and
7959 print-gensym is t, but only check print_depth if print-circle is nil.
7961 2012-04-20 Chong Yidong <cyd@gnu.org>
7963 * process.c (wait_reading_process_output): If EIO occurs on a pty,

7979 farther than the first row after the header line, if any.
7980 Don't consider the header-line row as "partially visible", even if

8018 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
8019 New extern decls, to avoid calling undeclared functions.
8020 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
8021 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
8022 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
8023 (NEED_MEM_INSERT): New macro.
8024 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
8025 Remove one incorrect comment and fix another.

8039 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
8040 Remove decls. This fixes an "It stinks!".

8044 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
8046 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

8061 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
8062 * s/netbsd.h, s/sol2-6.h:
8063 Remove definition of GC_MARK_STACK, since the default now works.
8064 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
8065 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
8066 no longer the default.
8067 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
8069 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
8071 * lread.c (lisp_file_lexically_bound_p):

8092 2012-04-11 Daniel Colascione <dancol@dancol.org>
8094 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
8095 against is gone. It's better to use vfork now so that when Cygwin
8096 gains a new, working vfork, we use it automatically (bug#10398).
8098 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

8119 being loaded (bug#10424).
8121 2012-04-09 Glenn Morris <rgm@gnu.org>
8123 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
8124 not just in the obarray, before snarfing them. (Bug#11036)
8126 * Makefile.in ($(leimdir)/leim-list.el):
8127 Pass EMACS rather than BUILT_EMACS.

8151 * minibuf.c (Fread_variable): Callers changed.
8153 2012-04-09 Eli Zaretskii <eliz@gnu.org>
8155 * xdisp.c (set_cursor_from_row): If the display string appears in
8156 the buffer at position that is closer to point than the position
8157 after the display string, display the cursor on the first glyph of
8158 the display string. Fixes cursor display when a 'display' text
8159 property immediately follows invisible text. (Bug#11094)
8161 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
8163 composite.c: use 'double' consistently
8164 * composite.c (get_composition_id): Use 'double' consistently
8165 instead of converting 'float' to 'double' and vice versa; this is
8166 easier to understand and avoids a GCC warning.
8168 2012-04-09 Glenn Morris <rgm@gnu.org>
8170 * Makefile.in: Generate leim-list with bootstrap-emacs, in
8171 preparation for dumping it with emacs. (Bug#4789)

8193 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
8194 (mark_memory): Mark Lisp_Objects only if pointers might hide in
8195 objects, as mark_maybe_pointer will catch them otherwise.
8196 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
8197 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

8201 Fix typo that broke non-Windows builds.
8202 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

8213 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
8214 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
8215 [!WINDOWSNT]: New macros.
8216 (init_libxml2_functions, libxml2_loaded_p): New functions.
8217 (parse_region): Call fn_xmlCheckVersion instead of using the macro
8218 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
8219 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
8220 Calls xmlCleanupParser only if libxml2 was loaded (or statically
8222 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
8223 Call init_libxml2_functions before calling libxml2 functions.
8224 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
8226 * emacs.c: Don't include libxml/parser.h.
8227 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
8228 xmlCleanupParser directly.
8230 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
8232 2012-04-07 Eli Zaretskii <eliz@gnu.org>
8234 * indent.c (Fvertical_motion): If there is a display string at
8235 point, use it.vpos to compute how many lines to backtrack after

8238 2012-04-06 Eli Zaretskii <eliz@gnu.org>
8240 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
8241 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
8242 about subtle differences between FETCH_CHAR* and STRING_CHAR*
8243 macros related to unification of CJK characters. For the details,
8244 see the discussion following the message here:
8245 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
8247 2012-04-04 Chong Yidong <cyd@gnu.org>
8249 * keyboard.c (Vdelayed_warnings_list): Doc fix.
8251 2012-04-01 Eli Zaretskii <eliz@gnu.org>
8253 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

8261 2012-03-31 Eli Zaretskii <eliz@gnu.org>
8263 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
8264 position we get to after a call to move_it_to fails the
8265 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
8266 only if we wind up in a string from display property. (Bug#11063)
8268 * window.c (Fdelete_other_windows_internal): Invalidate the row
8269 and column information about mouse highlight, so that redisplay
8270 restores it after reallocating the glyph matrices. (Bug#7464)
8272 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
8273 string comes from a `display' text property, use the buffer
8274 position of that property as if we actually saw that position in
8276 (move_it_by_lines): Remove the assertion that
8277 "it->current_x == 0 && it->hpos == 0" which can be legitimately
8278 violated when there's a before-string at the beginning of a line.
8281 2012-03-30 Eli Zaretskii <eliz@gnu.org>
8283 * xdisp.c (append_space_for_newline): If the default face was
8284 remapped, use the remapped face for the appended newline.
8285 (extend_face_to_end_of_line): Use the remapped default face for
8286 extending the face to the end of the line.
8287 (display_line): Call extend_face_to_end_of_line when the default
8288 face was remapped. (Bug#11068)
8290 2012-03-29 Eli Zaretskii <eliz@gnu.org>

8312 handle-select-window too (Bug#8996).
8314 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
8316 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
8318 2012-03-25 Kenichi Handa <handa@m17n.org>
8320 * dispextern.h (struct glyph): Change the bit length of
8321 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
8323 2012-03-24 Eli Zaretskii <eliz@gnu.org>
8325 * s/ms-w32.h (tzname): Include time.h before redirecting to
8326 _tzname. Fixes the MSVC build. (Bug#9960)

8330 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
8333 * xterm.c (XTread_socket): Only modify handling_signal if

8336 2012-03-23 Eli Zaretskii <eliz@gnu.org>
8338 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
8339 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
8340 when fetching a multibyte character consumes more bytes than
8341 CHAR_BYTES returns, due to unification of CJK characters in
8342 string_char. (Bug#11073)
8344 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
8346 * process.c (wait_reading_process_output): Handle pty disconnect
8347 by refraining from sending oneself a SIGCHLD (bug#10933).

8358 2012-03-21 Chong Yidong <cyd@gnu.org>
8360 * xfaces.c (Vface_remapping_alist): Doc fix.
8362 2012-03-20 Eli Zaretskii <eliz@gnu.org>
8364 * w32proc.c (Fw32_set_console_codepage)
8365 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

8376 it fit in a valid range (Bug#11003).
8378 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8380 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8381 that is not from display property, accept the row as a "cursor
8382 row" if one of the string's character has a non-nil `cursor'
8383 property. Fixes cursor positioning when there are newlines in
8384 overlay strings, e.g. in icomplete.el. (Bug#11035)
8386 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
8388 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
8390 2012-03-12 Chong Yidong <cyd@gnu.org>
8392 * eval.c (inhibit_lisp_code): Rename from
8393 inhibit_window_configuration_change_hook; move from window.c.
8395 * xfns.c (unwind_create_frame_1, Fx_create_frame):
8396 * window.c (run_window_configuration_change_hook)
8397 (syms_of_window): Callers changed.
8399 2012-03-11 Chong Yidong <cyd@gnu.org>
8401 * keymap.c (Fkey_description): Doc fix (Bug#9700).

8417 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8420 2012-03-03 Glenn Morris <rgm@gnu.org>

8435 * buffer.c (buffer-list-update-hook): Doc fix.
8437 2012-02-29 Eli Zaretskii <eliz@gnu.org>

8440 push_it before setting up the iterator for the first overlay
8441 string, even if we have an empty string loaded.
8442 (next_overlay_string): If there's an empty string on the iterator
8443 stack, pop the stack. (Bug#10903)
8445 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8447 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8448 Suggested by Stefan Monnier in
8449 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8450 * alloc.c (widen_to_Lisp_Object): New static function.
8451 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8452 and widening them to Lisp_Objects. This would work even if
8453 USE_LSB_TAG is defined and wide integers are used, which might
8454 happen in a future version of Emacs.
8456 2012-02-25 Chong Yidong <cyd@gnu.org>
8458 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

8474 (unwind_create_frame_1): New helper function.
8476 * window.c (inhibit_window_configuration_change_hook): New var.
8477 (run_window_configuration_change_hook): Obey it.
8478 (syms_of_window): Initialize it.
8480 2012-02-22 Chong Yidong <cyd@gnu.org>

8495 when computing $valmask.
8497 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8498 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8499 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8500 It's useless in that case, and it can cause problems on hosts
8501 that allocate halves of EMACS_INT values separately.
8502 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8503 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8504 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8505 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8506 it avoids undefined behavior on hosts where shifting right by more
8507 than the word width has undefined behavior.
8509 2012-02-19 Chong Yidong <cyd@gnu.org>
8511 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
8512 (Funhandled_file_name_directory, Ffile_name_as_directory)

8531 2012-02-15 Chong Yidong <cyd@gnu.org>
8533 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
8534 marked as special. Also, starting docstrings with * is obsolete.

8552 as that creates a dangerous corner case.
8554 * window.c (Fdelete_window_internal): Invalidate the mouse
8555 highlight (Bug#9904).
8557 2012-02-12 Glenn Morris <rgm@gnu.org>

8587 2012-02-07 Chong Yidong <cyd@gnu.org>
8589 * buffer.c (Fbuffer_local_variables)
8590 (buffer_lisp_local_variables): Handle unbound vars correctly;
8591 don't let Qunbound leak into Lisp.
8593 2012-02-07 Glenn Morris <rgm@gnu.org>
8595 * image.c (Fimagemagick_types): Doc fix.
8597 * image.c (imagemagick-render-type): Change it from a lisp object

8630 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
8632 Handle overflow when computing char display width (Bug#9496).
8633 * character.c (char_width): Return EMACS_INT, not int.
8634 (char_width, c_string_width): Check for overflow when
8635 computing the width; this is possible now that individual
8636 characters can have unbounded width. Problem introduced
8637 by merge from Emacs 23 on 2012-01-19.
8639 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

8668 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
8669 first 2 arguments are identical. This makes inserting large

8779 (Fmake_directory_internal): Use it.
8780 (do_auto_save_make_dir): Set it, instead of invoking chmod after

9309 behave as if the cursor position were at the window margin.
9311 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
9312 and the cursor position is out of bounds, behave as if the cursor

9343 * dispnew.c (verify_row_hash): Call row_hash for computing the
9344 hash code of a row, instead of duplicating code from xdisp.c.
9346 * dispextern.h (row_hash): Add prototype.
9348 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
9350 * frame.c (delete_frame): Don't delete the terminal when the last

9378 occurrences of window_nest to window_combination_limit.
9380 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
9382 * image.c (imagemagick_load_image): Fix typo.
9384 2011-11-14 Eli Zaretskii <eliz@gnu.org>
9386 * xdisp.c (display_line): Move the call to

9453 Avoid some portability problems by eschewing 'extern inline' functions.
9454 The trivial performance wins aren't worth the portability hassles; see
9455 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
9457 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

9505 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
9506 This is also needed for porting to any host where GC_MARK_STACK is
9507 not GC_MAKE_GCPROS_NOOPS.
9508 (which_symbols): Use it.
9510 2011-11-07 Kenichi Handa <handa@m17n.org>

9532 (window_box_right, window_box_right_offset): Declare extern.
9533 Otherwise, these inline functions do not conform to C99 and
9534 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
9535 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
9536 * intervals.c (adjust_intervals_for_insertion)
9537 (adjust_intervals_for_deletion): Now extern, because otherwise the
9538 extern inline functions 'offset_intervals' couldn't refer to it.
9539 (static_offset_intervals): Remove.
9540 (offset_intervals): Rewrite using the old contents of
9541 static_offset_intervals. The old version didn't conform to C99
9542 because an extern inline function contained a reference to an
9543 identifier with static linkage.

9565 (Fwindow_vscroll): Doc fix.
9566 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default

9856 * editfns.c: Rewrite current-time-zone so that it invokes
9857 the equivalent of (format-time-string "%Z") to get the time zone name.
9858 This fixes a bug when the time zone name contains characters that
9859 need converting from the system time locale to Emacs internal format.
9860 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9861 that patch fixed format-time-string to do the conversion, but
9862 I forgot to fix current-time-zone.
9863 (format_time_string): New function, containing most of
9864 what Fformat_time_string used to contain.
9865 (Fformat_time_string): Rewrite in terms of format_time_string.
9866 This doesn't change this function's behavior.
9867 (current-time-zone): Rewrite to use format_time_string.
9868 This fixes the bug reported by Michael Schierl in
9869 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9870 Jason Rumney's 2007-06-07 change worked around this bug, but
9872 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9874 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9876 * xdisp.c (start_display): If the character at POS is displayed
9877 via a display vector, reset IT->current.dpvec_index to zero.
9878 (try_window_reusing_current_matrix): If a line ends in a display
9879 vector or the next line starts in a display vector, continue
9880 redrawing the window even though the character position of
9881 start_row was reached.
9884 2011-10-18 Chong Yidong <cyd@gnu.org>
9886 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9887 with nobreak-char-display too.
9889 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9891 Fix part 3 of bug#9771.
9892 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9893 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9894 non-neutral characters if the current character is a paragraph
9895 separator (a.k.a. Newline). This avoids running the same
9896 expensive loop twice, once when we consume the preceding newline
9897 and the other time when the line actually needs to be displayed.
9898 Avoid the loop when we see neutrals on the base embedding level
9899 following a character whose directionality is the same as the
9900 paragraph's. This avoids running the expensive loop when a line
9901 ends in a long sequence of neutrals, like control characters.
9902 Add assertion against STRONG_AL type. Slightly rearrange code
9903 that determines the type of a neutral given the first non-neutral
9905 (bidi_level_of_next_char): Set next_en_pos to zero when
9906 invalidating its info.
9908 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9910 * xdisp.c (push_display_prop): Determine whether to record string
9911 or buffer position by IT->string, not by IT->method. Allow
9912 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9913 (move_it_vertically_backward): Don't look for character position
9914 immediately after the newline when in a continuation line.
9917 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9919 * window.c (coordinates_in_window): Rewrite and delabelize
9920 vertical border check. (Bug#5357) (Bug#9618)
9922 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9924 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9925 errors in XSetWindowBorder (bug#9310).
9927 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9929 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9930 avoid crash when xmalloc overrun checking is enabled.
9932 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9934 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9935 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9936 cursor motion with <left> and <right> arrow keys.
9938 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9939 some callers set that themselves.
9941 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9943 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9944 display string and the previous row comes from the same string and
9945 is empty. (Bug#9739) (Bug#9738)
9947 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9949 * doc.c (get_doc_string): Encode file name (bug#9735).
9951 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9953 * bidi.c (bidi_level_of_next_char):
9954 * xdisp.c (get_visually_first_element): Remove old incorrect
9955 comments regarding the Unicode Line Separator character.
9957 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9959 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9961 * alloc.c (Fgc_status): Do not access beyond zombies array
9962 boundary if nzombies > MAX_ZOMBIES.
9963 * alloc.c (dump_zombies): Add missing format specifier.
9965 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9967 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9968 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9970 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9971 Some packages use them to denote characters with modifiers.
9973 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9975 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9976 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9977 matching a pp-number. Rename parameter var to var1.
9979 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9981 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9983 2011-10-08 Glenn Morris <rgm@gnu.org>
9985 * callint.c (Fcall_interactively): Give a more explicit error for the
9986 'c' case with a non-character input. (Bug#8479)
9988 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9990 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9992 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9993 lines that are hscrolled on the left.
9995 * dispnew.c (buffer_posn_from_coords): Account for a possible
9996 presence of header-line. (Bug#4426)
9998 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
10000 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
10001 Don't advertise functionality which we discourage or doesn't work.
10003 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
10005 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
10006 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
10007 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
10008 this makes Emacs dump core during garbage collection on rare
10009 occasions. sizeof is obviously inferior to offsetof here, so
10010 stick with offsetof.
10011 (GC_POINTER_ALIGNMENT): New macro.
10012 (mark_memory): Omit 3rd (offset) arg; caller changed.
10013 Don't assume EMACS_INT alignment is the same as pointer alignment.
10015 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
10017 * keyboard.c (read_key_sequence_remapped): New var.
10018 (read_key_sequence): Compute remapping in the right buffer.
10019 (command_loop_1): Use read_key_sequence's remapping directly.
10021 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
10023 * dired.c (file_name_completion): Don't expand file name.
10024 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
10025 before checking file name handler.
10027 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
10028 they've been requested explicitly (bug#9591).
10030 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
10032 * keymap.c (Fsingle_key_description): Use make_specified_string
10033 instead of build_string to build string from push_key_description.
10036 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10038 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
10039 This fixes a Y2038 bug on 64-bit hosts.
10040 * buffer.c (reset_buffer):
10041 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
10042 (Fclear_buffer_auto_save_failure):
10043 Use 0, not -1, to represent an unset failure time, since time_t
10044 might not be signed.
10046 Remove dependency on glibc malloc internals.
10047 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10048 Move back here from lisp.h, but with their new implementations.
10049 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10050 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
10051 * charset.c (charset_table_init): New static var.
10052 (syms_of_charset): Use it instead of xmalloc. This removes a
10053 dependency on glibc malloc internals. See Eli Zaretskii's comment in
10054 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
10055 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10056 Move back to alloc.c.
10057 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10058 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
10060 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
10062 * nsterm.m (windowDidResize): Call x_set_window_size only when
10063 ns_in_resize is true. Otherwise set pixelwidth/height and
10064 call change_frame_size (Bug#9628).
10066 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10068 Port --enable-checking=all to Fedora 14 x86-64.
10069 * charset.c (syms_of_charset): Also account for glibc malloc's
10070 internal overhead when calculating the initial malloc maximum.
10072 Port --enable-checking=all to Fedora 14 x86.
10073 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10075 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
10076 (overrun_check_realloc, overrun_check_free):
10077 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
10078 That way, xmalloc returns a properly-aligned pointer even if
10079 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
10080 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
10081 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
10082 into account when calculating the initial malloc maximum.
10083 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10084 Move here from alloc.c, so that charset.c can use it too.
10085 Properly align; the old code wasn't right for common 32-bit hosts
10086 when configured with --enable-checking=all.
10087 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10088 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
10090 2011-09-29 Eli Zaretskii <eliz@gnu.org>
10092 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
10095 2011-09-28 Eli Zaretskii <eliz@gnu.org>
10097 * xdisp.c (compute_display_string_end): If there's no display
10098 string at CHARPOS, return -1.
10100 * bidi.c (bidi_fetch_char): When compute_display_string_end
10101 returns a negative value, treat the character as a normal
10102 character not covered by a display string. (Bug#9624)
10104 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
10106 * lread.c (Fread_from_string): Fix typo in docstring.
10108 2011-09-27 Eli Zaretskii <eliz@gnu.org>
10110 * xdisp.c (handle_invisible_prop): If invisible text ends on a
10111 newline, reseat the iterator instead of bidi-iterating there one
10112 character at a time. (Bug#9610)
10113 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
10114 TO_CHARPOS if the bidi iterator is at base embedding level.
10116 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
10118 * lread.c (readevalloop): Use correct code for NBSP.
10119 (read1): Likewise. (Bug#9608)
10121 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
10123 * dbusbind.c (Fdbus_register_signal): When service is not
10124 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
10126 2011-09-25 Glenn Morris <rgm@gnu.org>
10128 * buffer.c (truncate-lines): Doc fix.
10130 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
10132 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
10133 (Fset_window_next_buffers): Doc fix.
10135 2011-09-24 Glenn Morris <rgm@gnu.org>
10137 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
10139 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
10141 Fix minor problems found by static checking.
10142 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
10143 * indent.c (Fvertical_motion): Fix == vs = typo.
10145 2011-09-24 Eli Zaretskii <eliz@gnu.org>
10147 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
10148 Default value is now t. Doc fix.
10150 * indent.c (Fvertical_motion): Compute and apply the overshoot
10151 logic when moving up, not only when moving down. Fix the
10152 confusing name and values of the it_overshoot_expected variable;
10153 logic changes accordingly. (Bug#9254) (Bug#9549)
10155 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
10156 CHARPOS is covered by a display string which includes newlines.
10157 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
10158 is covered by a display string with embedded newlines.
10160 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
10162 * dbusbind.c (Fdbus_register_signal): Add match rule to
10163 Vdbus_registered_objects_table. (Bug#9581)
10164 (Fdbus_register_method, Vdbus_registered_objects_table):
10167 2011-09-24 Jim Meyering <meyering@redhat.com>
10169 do not ignore write error for any output size
10170 The previous change was incomplete.
10171 While it makes emacs --batch detect the vast majority of stdout
10172 write failures, errors were still ignored whenever the output size is
10173 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
10174 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
10175 && echo FAIL: ignored write error
10176 FAIL: ignored write error
10177 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
10178 && echo FAIL: ignored write error
10179 FAIL: ignored write error
10180 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
10182 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
10184 * emacs.c (Fkill_emacs): In noninteractive mode exit
10185 non-successfully if a write error occurred on stdout. (Bug#9574)
10187 2011-09-21 Eli Zaretskii <eliz@gnu.org>
10189 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
10192 * dispextern.h (struct it): Update the comment documenting what
10195 2011-09-20 Eli Zaretskii <eliz@gnu.org>
10197 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
10198 a display string, extend search for cursor position to end of row.
10199 (find_row_edges): If the row ends in a newline from a display
10200 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
10201 Handle the case of a display string with multiple newlines.
10202 (Fcurrent_bidi_paragraph_direction): Fix search for previous
10203 non-empty line. Fixes confusing cursor motion with arrow keys at
10204 the beginning of a line that starts with whitespace.
10206 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10208 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
10211 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
10213 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
10214 boolean (Bug#9154).
10216 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10218 * xdisp.c (display_line): Record maximum and minimum buffer
10219 positions even if no glyphs were produced (e.g., by a zero-width
10220 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
10221 buffer positions that will be removed from the glyph row because
10223 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
10224 column is beyond frame width: don't subtract 1 "pixel" when
10225 computing width of the stretch.
10226 (reseat_at_next_visible_line_start): Undo the change made on
10227 2011-09-17 that saved paragraph information and restored it after
10228 the call to `reseat'. (Bug#9545)
10230 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10232 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
10233 and turn window cursor on if cleared (Bug#9415).
10235 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
10237 * search.c (boyer_moore): Take unibyte characters from pattern
10238 literally. (Bug#9458)
10240 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10242 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
10244 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
10246 Fix minor problem found by static checking.
10247 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
10248 initialized, to pacify gcc -Wuninitialized.
10250 * fileio.c: Report proper errno when syscall falls.
10251 (Finsert_file_contents): Save and restore errno,
10252 so that report_file_error outputs the correct diagnostic.
10253 (Fwrite_region) [CLASH_DETECTION]: Likewise.
10255 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10257 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
10259 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10261 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
10262 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
10264 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10266 * xdisp.c (reseat_at_next_visible_line_start): Keep information
10267 about the current paragraph and restore it after the call to reseat.
10269 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
10270 (bidi_find_paragraph_start): Search back for paragraph beginning
10271 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
10272 (bidi_move_to_visually_next): Only trigger paragraph-related
10273 computations when the last character is a newline or at EOB, not
10274 just any NEUTRAL_B. (Bug#9470)
10276 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
10277 truncated lines if point is covered by a display string. (Bug#9524)
10279 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
10281 * xselect.c: Relax test for outgoing X longs (Bug#9498).
10282 (cons_to_x_long): New function.
10283 (lisp_data_to_selection_data): Use it. Correct the test for
10284 short-versus-long data; it was negated. Break out of vector
10285 loop, for efficiency, when a long datum is discovered.
10287 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
10289 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
10291 2011-09-16 Eli Zaretskii <eliz@gnu.org>
10293 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
10294 GCC PR/17406) by declaring this function with external scope.
10296 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10298 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
10299 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
10301 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
10303 * editfns.c (Fformat): Correctly handle text properties on "%%".
10305 2011-09-15 Eli Zaretskii <eliz@gnu.org>
10307 * xterm.c (x_draw_composite_glyph_string_foreground):
10308 * w32term.c (x_draw_composite_glyph_string_foreground):
10309 * term.c (encode_terminal_code):
10310 * composite.c (composition_update_it, get_composition_id):
10311 * xdisp.c (get_next_display_element)
10312 (fill_composite_glyph_string): Add comments about special meaning
10313 of TAB characters in a composition.
10315 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10317 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
10318 This occurs when processing a multibyte format.
10319 Problem reported by Wolfgang Jenker.

10323 * xdisp.c (try_cursor_movement): Only check for exact match if
10324 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
10326 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10328 Remove unused external symbols.
10329 * dispextern.h (calc_pixel_width_or_height): Remove decl.
10330 * xdisp.c (calc_pixel_width_or_height): Now static.
10331 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
10332 * indent.c (check_display_width):
10333 * w32term.c: Fix comment to match code.
10334 * xterm.c, xterm.h (x_catching_errors): Remove.
10336 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10338 * xselect.c: Use signed conversions more consistently (Bug#9498).
10339 (selection_data_to_lisp_data): Assume incoming selection data are
10340 signed integers, not unsigned. This is to be consistent with
10341 outgoing selection data, which was modified to use signed integers
10342 in as part of the fix to Bug#9196 in response to Jan D.'s comment
10343 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
10344 expects long, not unsigned long.
10346 2011-09-14 Eli Zaretskii <eliz@gnu.org>
10348 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
10349 computation of loop end. Reported by Johan Bockgård
10352 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
10354 * frame.c (Fother_visible_frames_p): Function deleted.
10356 2011-09-12 Eli Zaretskii <eliz@gnu.org>
10358 * indent.c (compute_motion): Process display vector front to back
10359 rather than the other way around. (Bug#2496)
10361 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
10363 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
10365 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
10367 * minibuf.c (Fread_from_minibuffer): Doc fix.
10369 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10371 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
10372 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
10374 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
10376 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
10377 value for non-existent files.
10379 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10381 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10382 set its "size" to -1. This will set the modtime_size field of
10383 the corresponding buffer to -1, which is what
10384 verify-visited-file-modtime expects for files that do not exist.
10387 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
10389 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10391 * lisp.h: ... from here. push_key_description is no longer
10392 defined in keyboard.c, so its declaration should not be in
10393 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10394 logically belongs with push_key_description.
10396 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10398 * buffer.h: Include <sys/types.h> instead of <time.h>.
10399 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
10400 Problem reported by Herbert J. Skuhra.
10402 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
10404 * xml.c (parse_region): Make the parsing work for
10405 non-comment-starting XML files again (bug#9144).
10407 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
10409 * image.c (gif_load): Fix calculation of bottom and right corner.
10412 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10414 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10415 redisplay in small windows.
10417 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10419 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10421 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10423 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10424 Operate on live windows only.
10426 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10428 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10430 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10432 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10433 only under bidi iteration.
10435 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10437 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10439 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10441 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10442 Without this fix, the command to link temacs failed due to an
10443 undefined symbol __builtin_isnan. This is because
10444 /usr/include/iso/math_c99.h #defines isnan(x) to
10445 __builtin_isnan(x), but the bundled gcc, which identifies itself
10446 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10448 * floatfns.c (isnan): #undef, and then #define to a clone of
10450 (Fisnan): Always define, since it's always available now.
10451 (syms_of_floatfns): Always define isnan at the Lisp level.
10453 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10455 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10457 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10459 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10460 The previous code assumed that file offsets (off_t values) fit in
10461 EMACS_INT variables, which is not true on typical 32-bit hosts.
10462 The code messed up by falsely reporting buffer overflow in cases
10463 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10464 when "big" contains more than 2**29 bytes, even though this
10465 inserts just one byte and does not overflow the buffer.
10466 (Finsert_file_contents): Store file offsets as off_t
10467 values, not as EMACS_INT values. Check for overflow when
10468 converting between EMACS_INT and off_t. When checking for
10469 buffer overflow or for overlap, take the offsets into account.
10470 Don't use EMACS_INT for small values where int suffices.
10471 When checking for overlap, fix a typo: ZV was used where
10472 ZV_BYTE was intended.
10473 (Fwrite_region): Don't assume off_t fits into 'long'.
10474 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10476 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10478 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10480 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10482 sprintf-related integer and memory overflow issues (Bug#9412).
10484 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10485 (esprintf, exprintf, evxprintf): New functions.
10486 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10487 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10488 (modify_event_symbol): Do not assume that the length of
10489 name_alist_or_stem is safe to alloca and fits in int.
10490 (Fexecute_extended_command): Likewise for function name and binding.
10491 (Frecursion_depth): Wrap around reliably on integer overflow.
10492 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10493 since some callers pass EMACS_INT values.
10494 (Fsingle_key_description): Don't crash if symbol name contains more
10495 than MAX_ALLOCA bytes.
10496 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10497 (get_minibuffer): Arg is now EMACS_INT, not int.
10498 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10499 (esprintf, exprintf, evxprintf): New decls.
10500 * window.h (command_loop_level, minibuf_level): Reflect API changes.
10502 * dbusbind.c (signature_cat): New function.
10503 (xd_signature, Fdbus_register_signal):
10504 Do not overrun buffer; instead, report string overflow.
10506 * dispnew.c (add_window_display_history): Don't overrun buffer.
10507 Truncate instead; this is OK since it's just a log.
10509 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10510 even if the time zone offset is outlandishly large.
10511 Don't mishandle offset == INT_MIN.
10513 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10514 when creating daemon; the previous buffer-overflow check was incorrect.
10516 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10517 which has the guts of the old verror function.
10519 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10520 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10522 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10523 (font_unparse_xlfd): Don't blindly alloca long strings.
10524 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10525 fits in int, when using sprintf. Use single snprintf to count
10526 length of string rather than counting it via multiple sprintfs;
10527 that's simpler and more reliable.
10528 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10529 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10530 sprintf, in case result does not fit in int.
10532 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10533 (fontset_from_font): Print it.
10535 * frame.c (tty_frame_count): Now printmax_t, not int.
10536 (make_terminal_frame, set_term_frame_name): Print it.
10537 (x_report_frame_params): In X, window IDs are unsigned long,
10538 not signed long, so print them as unsigned.
10539 (validate_x_resource_name): Check for implausibly long names,
10540 and don't assume name length fits in 'int'.
10541 (x_get_resource_string): Don't blindly alloca invocation name;
10542 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10545 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10546 (xg_check_special_colors, xg_set_geometry):
10547 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10549 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10550 Use esprintf, not sprintf, in case result does not fit in int.
10552 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10553 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10554 it as a large positive number.
10555 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10556 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10558 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10559 in case result does not fit in int.
10561 * print.c (float_to_string): Detect width overflow more reliably.
10562 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10563 buffer overrun. Don't assume list length fits in 'int'. Treat
10564 print length of 0 as 0, not as infinity; to be consistent with other
10565 uses of print length in this function. Don't overflow print length
10566 index. Don't assume hash table size fits in 'long', or that
10567 vectorlike size fits in 'unsigned long'.
10569 * process.c (make_process): Use printmax_t, not int, to format
10570 process-name gensyms.
10572 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10574 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10575 to avoid potential buffer overrun.
10577 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10578 if X resource line is longer than 512 bytes.
10580 * xfns.c (x_window): Make sprintf buffer a bit bigger
10581 to avoid potential buffer overrun.
10583 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10585 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10587 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10589 Integer overflow fixes for scrolling, etc.
10590 Without these, Emacs silently mishandles large integers sometimes.
10591 For example, "C-u 4294967297 M-x recenter" was treated as if
10592 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10594 * xdisp.c (try_window_id): Check Emacs fixnum range before
10595 converting to 'int'.
10597 * window.c (window_scroll_line_based, Frecenter):
10598 Check that an Emacs fixnum is in range before assigning it to 'int'.
10599 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10600 values converted from Emacs fixnums.
10601 (Frecenter): Don't wrap around a line count if it is out of 'int'
10602 range; instead, treat it as an extreme value.
10603 (Fset_window_configuration, compare_window_configurations):
10604 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10606 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10607 that can exceed INT_MAX. Check that EMACS_INT value is in range
10608 before assigning it to the (possibly-narrower) index.
10609 (match_limit): Don't assume that a fixnum can fit in 'int'.
10611 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10614 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10615 (Fvertical_motion): Don't wrap around LINES values that don't fit
10616 in 'int'. Instead, treat them as extreme values. This is good
10617 enough for windows, which can't have more than INT_MAX lines anyway.
10619 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10621 * Require libxml/parser.h to avoid compilation warning.
10623 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10625 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10626 since this reportedly can destroy thread storage.
10628 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10630 * syntax.c (find_defun_start): Update all cache variables if
10631 exiting early (Bug#9401).
10633 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10635 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10637 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10638 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10639 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10641 * term.c (tty_append_glyph): New function.
10642 (produce_stretch_glyph): Static function and its prototype deleted.
10644 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10647 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10649 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10650 when checking :margin (Bug#9390).
10651 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10652 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10653 so that the name doesn't mislead. All uses changed.
10655 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10657 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
10660 2011-08-27 Eli Zaretskii <eliz@gnu.org>
10662 * xdisp.c (move_it_to): Don't bail out early when reaching
10663 position beyond to_charpos, if we are scanning backwards.
10664 (move_it_vertically_backward): When DY == 0, make sure we get to
10665 the first character in the line after the newline.
10667 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10669 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10670 (ccl_driver): Do not generate an out-of-range pointer.
10671 (Fccl_execute_on_string): Remove unnecessary check for
10672 integer overflow, noted by Stefan Monnier in
10673 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10674 Remove a FIXME that didn't need fixing.
10675 Simplify the newly-introduced buffer reallocation code.
10677 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10679 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10681 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10683 Integer and memory overflow issues (Bug#9196).
10685 * doc.c (get_doc_string): Rework so that
10686 get_doc_string_buffer_size is the actual buffer size, rather than
10687 being 1 less than the actual buffer size; this makes xpalloc more
10690 * image.c (x_allocate_bitmap_record, cache_image):
10691 * xselect.c (Fx_register_dnd_atom):
10692 Simplify previous changes by using xpalloc.
10694 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10695 since either will do and ptrdiff_t is convenient with xpalloc.
10697 * charset.c (charset_table_size)
10698 (struct charset_sort_data.priority): Now ptrdiff_t.
10699 (charset_compare): Don't overflow if priorities differ greatly.
10700 (Fsort_charsets): Don't assume list length fits in int.
10701 Check for size-calculation overflow when allocating sort data.
10702 (syms_of_charset): Allocate an initial charset table that is
10703 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10705 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10707 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10708 The actual value is always <= INT_MAX, and leaving it unsigned made
10709 overflow checking harder.
10711 * dispextern.h (struct glyph_matrix.rows_allocated)
10712 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10713 with xpalloc. The values are still always <= INT_MAX.
10715 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10717 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10718 (SAFE_NALLOCA): New macro.
10720 * region-cache.c (struct boundary.pos, find_cache_boundary)
10721 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10722 (set_cache_region, invalidate_region_cache)
10723 (revalidate_region_cache, know_region_cache, region_cache_forward)
10724 (region_cache_backward, pp_cache):
10725 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10726 so that ptrdiff_t * can be passed to xpalloc.
10727 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
10728 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
10729 (pp_cache): Don't assume cache_len fits in int.
10730 * region-cache.h: Adjust extern decls to match.
10732 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
10733 EMACS_INT, since either will do, for xpalloc.
10735 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
10736 (xnmalloc, xnrealloc, xpalloc): New functions.
10738 * bidi.c (bidi_shelve_header_size): New constant.
10739 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
10740 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
10742 * bidi.c (bidi_cache_shrink):
10743 * buffer.c (overlays_at, overlays_in, record_overlay_string)
10745 Don't update size of array until after memory allocation succeeds,
10746 because xmalloc/xrealloc may not return.
10747 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10748 now that we have proper integer overflow checking.
10749 (record_overlay_string, overlay_strings): Catch overflows when
10750 calculating size of overlay_str_buf.
10752 * callproc.c (Fcall_process): Check for size overflow when
10753 calculating size of args2.
10754 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
10755 Normally we prefer signed values, but sticking with ptrdiff_t would
10756 require adding more-complicated checks.
10758 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10759 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
10760 Redo buffer-overflow calculations to avoid integer overflow.
10761 Add a FIXME comment where memory seems to be over-allocated.
10763 * character.c (Fstring): Check for size-calculation overflow.
10765 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
10766 unnecessary integer overflow. Check for size overflow.
10767 (encode_coding_object): Don't update size until xmalloc succeeds.
10769 * composite.c (get_composition_id): Check for overflow in glyph
10770 length calculations.
10772 Integer and memory overflow fixes for display code.
10773 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
10774 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
10775 (scrolling_window): Check for overflow in size calculations.
10776 (line_draw_cost, realloc_glyph_pool, add_row_entry):
10777 Don't assume glyph table len fits in int.
10778 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)

10799 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10801 * emacs.c (main): Do not reallocate argv, since there is a null at
10802 the end that can be overwritten, and this way there's no need to
10803 worry about size-calculation overflow.

10921 (Fx_change_window_property): Use ptrdiff_t, not int, to count
10922 sizes, since they can exceed INT_MAX in size. Check for size

10933 (X_LONG_MIN): New macros.
10934 Use them to make the following changes clearer.
10935 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
10936 This change doesn't affect the value now, but it may help remind
10937 future maintainers not to raise the value too much later.
10938 (SELECTION_QUANTUM): Remove, replacing with ...
10939 (selection_quantum): ... new function, which avoids overflow.
10941 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10942 assumption that selection length fits in 'int'.

10959 Don't store size until memory allocation succeeds.
10960 (x_get_window_property): Plug memory leak on memory exhaustion.
10961 Don't double-block input; malloc is safe here. Don't assume 2**34
10962 - 4 fits in unsigned long. Add an xassert to check
10963 XGetWindowProperty overflow. Be more careful about overflow
10964 calculations, and distinguish size from memory overflow better.
10965 (receive_incremental_selection): When tracing, don't assume
10966 unsigned int is less than INT_MAX.
10967 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

10971 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10972 result parameters unless successful. Rely on cons_to_unsigned
10973 to report problems with elements; the old code wasn't right anyway.
10974 (x_check_property_data): Check for int overflow; we cannot use
10975 a wider type due to X limits.

11008 * lisp.h (hash_lookup, hash_put):
11009 * minibuf.c (Ftest_completion):
11010 Use ptrdiff_t for hash table indexes, not int (which is too
11011 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
11012 32-bit --with-wide-int hosts).
11014 * charset.c (Fdefine_charset_internal): Check for integer overflow.
11015 Add a FIXME comment about memory leaks.

11023 with outlandish widths.
11024 * character.h (sanitize_tab_width): Rename from sanitize_width,
11025 now that we have two such functions. All uses changed.

11044 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
11045 (x_send_scroll_bar_event): Likewise. Check that the size does not
11046 exceed limits imposed by XClientMessageEvent, as well as the usual
11047 ptrdiff_t and size_t limits.
11049 * keyboard.c: Overflow, signedness and related fixes.
11050 (make_lispy_movement): Use same integer type in forward decl
11051 that is used in the definition.
11052 (read_key_sequence, keyremap_step):
11053 Change bufsize argument back to int, undoing my 2011-03-30 change.
11054 We prefer signed types, and int is wide enough here.
11055 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
11056 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
11057 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
11058 length, not size_t. Use ptrdiff_t for index, not int.
11059 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
11060 possibility of integer overflow.

11088 Prefer int to unsigned where either will do.
11089 (tiff_handler): New function, combining the cores of the
11090 old tiff_error_handler and tiff_warning_handler.

11092 stack buffer overflows. It uses only the features of vsnprintf
11093 that are common to both POSIX and native Microsoft.
11094 (tiff_error_handler, tiff_warning_handler): Use it.
11095 (tiff_load, gif_load, imagemagick_load_image):
11096 Don't assume :index value fits in 'int'.
11097 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
11098 (imagemagick_load_image): Check that crop parameters fit into
11099 the integer types that MagickCropImage accepts. Don't assume
11100 Vimagemagick_render_type has a nonnegative value. Don't assume
11101 size_t fits in 'long'.
11102 (gs_load): Use printmax_t to print the widest integers possible.

11116 (handle_single_display_spec): If the display spec is of the form
11117 `(space ...)', and specifies display in the text area, return 2
11119 (try_cursor_movement): Check for the need to scroll more
11120 accurately, and prefer exact match for point under bidi.
11121 Don't advance `row' beyond the last row of the window.

11142 positioning on the newline at EOL of R2L text within L2R
11143 paragraph, and vice versa.
11144 (try_cursor_movement): Check continued rows, in addition to
11145 continuation rows. Fixes unwarranted scroll when point enters a
11146 continued line of R2L text within an L2R paragraph, or vice versa.
11147 (cursor_row_p): Consider the case of point being equal to
11148 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

11177 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
11178 instead of CHAR_TO_BYTE. Fixes a crash when a completion
11179 candidate is selected by the mouse, and that candidate has a
11180 composed character under the mouse.
11182 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
11183 coordinates reported by pos-visible-in-window-p for a composed

11193 consider it a hit if to_charpos is anywhere in the range of the
11194 composed buffer positions.
11196 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
11198 * image.c (gif_load): Don't assume that each subimage has the same
11199 dimensions as the base image. Handle disposal method that is
11200 "undefined" by the gif spec (Bug#9335).
11202 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
11204 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

11210 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
11211 from an Org mode buffer to a Speedbar frame.
11213 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
11214 a composition, take its buffer position from IT->cmp_it.charpos.
11215 Fixes cursor positioning at the beginning of a line that begins
11216 with a composed character.
11218 2011-08-18 Eli Zaretskii <eliz@gnu.org>
11220 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
11221 character bidirectional type, use STRONG_L instead. Fixes crashes
11222 in a buffer produced by `describe-categories'.
11224 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
11225 members before the level stack, so they would be saved and
11226 restored when copying iterator state. Fixes incorrect reordering
11227 around TABs covered by display properties.
11229 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
11231 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
11233 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
11235 * eval.c (internal_condition_case, internal_condition_case_1)
11236 (internal_condition_case_2, internal_condition_case_n):
11237 Remove unnecessary aborts (Bug#9081).
11239 2011-08-17 Eli Zaretskii <eliz@gnu.org>
11241 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
11242 has no `load' handler, try opening the file locally. (Bug#9311)
11244 2011-08-16 Ken Brown <kbrown@cornell.edu>
11246 * gmalloc.c: Expand comment.
11248 2011-08-16 Eli Zaretskii <eliz@gnu.org>
11250 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
11251 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
11253 2011-08-16 Ken Brown <kbrown@cornell.edu>
11255 Fix memory allocation problems in Cygwin build (Bug#9273).

11262 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
11264 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
11265 in the static heap.
11266 [CYGWIN] (special_realloc): New function.
11267 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
11268 requests to realloc storage in the static heap.

11279 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
11281 * dispextern.h: Fix a typo in the comment to bidi_type_t.
11283 * chartab.c: Improve commentary for the uniprop_table API.
11285 * bidi.c (bidi_paragraph_init): Support zero value of
11286 bidi_ignore_explicit_marks_for_paragraph_level.
11287 (bidi_initialize): Use uniprop_table instead of including
11288 biditype.h and bidimirror.h.
11290 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
11291 coordinates of the iterator when restoring from ppos_it.
11294 2011-08-14 Kenichi Handa <handa@m17n.org>
11296 * process.c (create_process): Call setup_process_coding_systems
11297 after the pid of the process is set to -1 (Bug#8162).
11299 2011-08-14 Eli Zaretskii <eliz@gnu.org>
11301 * xdisp.c (move_it_in_display_line_to): Don't invoke
11302 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
11303 ppos_it. Fixes vertical cursor motion when line beginning is
11304 covered by an image. (Bug#9296)
11306 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
11308 * nsterm.h (ns_run_ascript): Declare.
11309 (NSAPP_DATA2_RUNASSCRIPT): Define.
11311 * nsfns.m (as_script, as_result, as_status): New static variables.
11312 (ns_run_ascript): New function.
11313 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
11314 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
11315 the event loop. Get status from as_status (Bug#7276).
11317 * nsterm.m (sendEvent): If event is NSApplicationDefined and
11318 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
11319 the event loop (Bug#7276).
11321 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
11323 * gnutls.c (QCgnutls_bootprop_priority)
11324 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
11325 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
11326 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
11327 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
11328 (QCgnutls_bootprop_verify_hostname_error)
11329 (QCgnutls_bootprop_callbacks_verify): Rename from
11330 Qgnutls_bootprop_..., all uses changed.
11332 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
11335 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
11337 * xfaces.c (Qframe_set_background_mode): Now static.

11342 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
11344 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
11345 (Fnetwork_interface_list): Allocate in increments of bytes instead
11346 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
11347 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
11349 (struct ifflag_def): notrailers is smart on OSX.
11350 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
11351 Get hardware address with getifaddrs if available.
11353 2011-08-12 Eli Zaretskii <eliz@gnu.org>
11355 * xdisp.c (iterate_out_of_display_property): xassert that
11356 IT->position is set to within IT->object's boundaries. Break from
11357 the loop as soon as EOB is reached; avoids infloops in redisplay
11358 when IT->position is set up wrongly due to some bug.
11359 Set IT->current to match the bidi iterator unconditionally.
11360 (push_display_prop): Allow GET_FROM_STRING as IT->method on
11361 entry. Force push_it to save on the stack the current
11362 buffer/string position, to be restored by pop_it. Fix flags in
11363 the iterator structure wrt the object coming from a display
11364 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
11365 properties. (Bug#9284)
11367 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
11369 * fontset.c (fontset_get_font_group): Add proper type checks.
11372 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

11375 and LC_VERSION_MIN_MACOSX.
11376 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
11377 (dump_it) [LC_FUNCTION_STARTS]: Use it.
11379 2011-08-08 Eli Zaretskii <eliz@gnu.org>
11381 * xdisp.c (forward_to_next_line_start): Allow to use the
11382 no-display-properties-and-no-overlays under bidi display.
11383 Set disp_pos in the bidi iterator to avoid searches for display
11384 properties and overlays.
11386 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
11388 * editfns.c (Fset_time_zone_rule): Document relationship with the

11392 the font entity extracted from the cache (Bug#8109).
11394 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
11396 * composite.c (autocmp_chars): Don't reset point. That is done by
11397 restore_point_unwind (Bug#5984).
11399 2011-08-07 Juri Linkov <juri@jurta.org>
11401 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
11402 to show the arg `TIME' instead of `TIMEVAL'.
11404 2011-08-06 Eli Zaretskii <eliz@gnu.org>
11406 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
11407 display property strides EOL and includes a newline, as in
11408 longlines-mode. (Bug#9254)
11409 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
11410 word-wrap under bidirectional display. (Bug#9224)
11412 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
11413 is non-zero, even if the data buffer is NULL. Fixes a crash in
11414 vertical-motion with longlines-mode. (Bug#9254)
11416 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11418 * bidi.c <bidi_cache_total_alloc>: Now static.
11419 (bidi_initialize): Initialize bidi_cache_total_alloc.
11421 * xdisp.c (display_line): Release buffer allocated for shelved bidi
11424 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
11425 amount allocated this far in `bidi_cache_total_alloc'.
11426 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
11427 non-zero, only free the data buffer without restoring the cache
11428 contents. All callers changed.
11430 * dispextern.h (bidi_unshelve_cache): Update prototype.
11432 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
11433 (move_it_in_display_line, move_it_to)
11434 (move_it_vertically_backward, move_it_by_lines): Replace the call
11435 to xfree to an equivalent call to bidi_unshelve_cache.
11436 (move_it_in_display_line_to): Fix logic of returning
11437 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
11439 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11441 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
11442 came from a string character with a `cursor' property. (Bug#9229)
11444 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11446 * Makefile.in (LIB_PTHREAD): New variable.
11447 (LIBES): Add LIB_PTHREAD (Bug#9216).
11449 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
11450 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
11452 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
11454 * regex.c (re_iswctype): Remove some redundant boolean conversions.
11456 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11458 * xterm.c (x_find_topmost_parent): New function.
11459 (x_set_frame_alpha): Find topmost parent window with
11460 x_find_topmost_parent and set the property there also (bug#9181).
11461 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
11463 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
11465 * callproc.c (Fcall_process): Avoid vfork clobbering
11466 the local vars buffer, coding_systems, current_dir.
11468 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
11470 * keymap.c (Fmake_composed_keymap): Move to subr.el.
11472 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
11474 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
11475 so that it is not optimized away.
11477 * xdisp.c (compute_display_string_pos): Remove unused local.
11479 2011-08-02 Eli Zaretskii <eliz@gnu.org>
11481 Fix slow cursor motion and scrolling in large buffers with
11482 selective display, like Org Mode buffers. (Bug#9218)
11484 * dispextern.h (struct bidi_it): New member disp_prop_p.
11486 * xdisp.c: Remove one-slot cache of display string positions.
11487 (compute_display_string_pos): Accept an additional argument
11488 DISP_PROP_P; callers changed. Scan at most 5K characters forward
11489 for a display string or property. If found, set DISP_PROP_P
11492 * bidi.c (bidi_fetch_char): Accept an additional argument
11493 DISP_PROP_P, and pass it to compute_display_string_pos.
11494 Only handle text covered by a display string if DISP_PROP_P is returned
11495 non-zero. All callers of bidi_fetch_char changed.
11497 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
11499 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
11501 2010-12-03 Don March <don@ohspite.net>
11503 * keymap.c (Fdefine_key): Fix non-prefix key error message when
11504 last character M-[char] is translated to ESC [char] (bug#7541).
11506 2011-08-02 Kenichi Handa <handa@m17n.org>
11508 * lisp.h (uniprop_table): Extern it.
11510 * chartab.c (uniprop_table): Make it non-static.
11512 2011-08-01 Eli Zaretskii <eliz@gnu.org>
11514 * xdisp.c (forward_to_next_line_start): Accept additional argument
11515 BIDI_IT_PREV, and store into it the state of the bidi iterator had
11517 (reseat_at_next_visible_line_start): Use the bidi iterator state
11518 returned by forward_to_next_line_start to restore the state of
11519 it->bidi_it after backing up to previous newline. (Bug#9212)
11521 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
11523 * regex.c (re_comp): Protoize.
11524 (re_exec): Fix return type.
11525 (regexec): Fix type of `ret'. (Bug#9203)
11527 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11529 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
11530 This is needed if max-image-size is a floating-point number.
11532 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11534 * print.c (print_object): Print empty symbol as ##.
11536 * lread.c (read1): Read ## as empty symbol.
11538 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11540 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
11541 setting frame foreground color (Bug#9175).
11542 (x_set_background_color): Likewise.
11544 * nsmenu.m (-setText): Size tooltip dimensions precisely to
11545 contents (Bug#9176).
11546 (EmacsTooltip -init): Remove bezels and add shadows to
11549 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
11550 or scroll bar (Bug#8470).
11552 * nsfont.m (nsfont_open): Remove assignment to voffset and
11553 unnecessary vars hshink, expand, hd, full_height, min_height.
11554 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
11556 * nsterm.h (nsfont_info): Remove voffset field.
11558 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11560 Implement strike-through and overline on NextStep (Bug#8863).
11562 * nsfont.m (nsfont_open): Use underline position provided by font,
11563 instead of hard-coded value of 2.
11564 (nsfont_draw): Call ns_draw_text_decoration instead.
11566 * nsterm.h: Add declaration for ns_draw_text_decoration.
11568 * nsterm.m (ns_draw_text_decoration): New function for drawing
11569 underline, overline, and strike-through.
11570 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
11571 ns_draw_text_decoration. Change treatment of cursor drawing to
11572 accommodate underlining, etc.
11574 2011-07-28 Eli Zaretskii <eliz@gnu.org>
11576 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
11579 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11581 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11582 Without this fix, if a signal arrives just after memory fills up,
11583 'malloc' might be invoked reentrantly.
11585 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11586 In other words, assume that every image size is allowed, on non-X
11587 hosts. This assumption is probably wrong, but it lets Emacs compile.
11589 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11591 * regex.c (re_iswctype): Convert return values to boolean.
11593 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
11595 * xdisp.c (compute_display_string_pos): Don't use cached display
11596 string position if the buffer had its restriction changed.
11599 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11601 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11603 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11605 Integer signedness and overflow and related fixes. (Bug#9079)
11607 * bidi.c: Integer size and overflow fixes.
11608 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
11609 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
11610 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11611 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11612 (bidi_find_other_level_edge):
11613 Use ptrdiff_t instead of EMACS_INT where either will do.
11614 This works better on 32-bit hosts configured --with-wide-int.
11615 (bidi_cache_ensure_space): Check for size-calculation overflow.
11616 Use % rather than repeated addition, for better worst-case speed.
11617 Don't set bidi_cache_size until after xrealloc returns, because it
11619 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11620 (bidi_cache_ensure_space): Also check that the bidi cache size
11621 does not exceed that of the largest Lisp string or buffer. See Eli
11622 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11624 * alloc.c (__malloc_size_t): Remove.
11625 All uses replaced by size_t. See Andreas Schwab's note
11626 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11628 * image.c: Improve checking for integer overflow.
11629 (check_image_size): Assume that f is nonnull, since
11630 it is always nonnull in practice. This is one less thing to
11631 worry about when checking for integer overflow later.
11632 (x_check_image_size): New function, which checks for integer
11633 overflow issues inside X.
11634 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11635 This removes the need for a memory_full check.
11636 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11637 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11638 (xbm_read_bitmap_data): Change locals back to 'int', since
11639 their values must fit in 'int'.
11640 (xpm_load_image, png_load, tiff_load):
11641 Invoke x_create_x_image_and_pixmap earlier,
11642 to avoid much needless work if the image is too large.
11643 (tiff_load): Treat overly large images as if
11644 x_create_x_image_and_pixmap failed, not as malloc failures.
11645 (gs_load): Use x_check_image_size.
11647 * gtkutil.c: Omit integer casts.
11648 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11649 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11651 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11653 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11654 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11655 would wrongly return t on a 64-bit host.
11657 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11658 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11659 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11660 and therefore cause GCC to emit a bogus diagnostic in some cases.
11662 * image.c: Integer signedness and overflow and related fixes.
11663 This is not an exhaustive set of fixes, but it's time to
11664 record what I've got.
11665 (lookup_pixel_color, check_image_size): Remove redundant decls.
11666 (check_image_size): Don't assume that arbitrary EMACS_INT values
11667 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11668 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11669 (tiff_load, imagemagick_load_image):
11670 Check for overflow in size calculations.
11671 (x_create_x_image_and_pixmap): Remove unnecessary test for
11672 xmalloc returning NULL; that can't happen.
11673 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11674 (xpm_color_bucket): Use better integer hashing function.
11675 (xpm_cache_color): Don't possibly over-allocate memory.
11676 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11677 (gif_memory_source):
11678 Use ptrdiff_t, not int or size_t, to record sizes.
11679 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11680 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11681 either works, as we prefer signed integers.
11682 (tiff_read_from_memory, tiff_write_from_memory):
11683 Return tsize_t, not size_t, since that's what the TIFF API wants.
11684 (tiff_read_from_memory): Don't fail simply because the read would
11685 go past EOF; instead, return a short read.
11686 (tiff_load): Omit no-longer-needed casts.
11687 (Fimagemagick_types): Don't assume size fits into 'int'.
11689 Improve hashing quality when configured --with-wide-int.
11690 * fns.c (hash_string): New function, taken from sxhash_string.
11691 Do not discard information about ASCII character case; this
11692 discarding is no longer needed.
11693 (sxhash-string): Use it. Change sig to match it. Caller changed.
11694 * lisp.h: Declare it.
11695 * lread.c (hash_string): Remove, since we now use fns.c's version.
11696 The fns.c version returns a wider integer if --with-wide-int is
11697 specified, so this should help the quality of the hashing a bit.
11699 * emacs.c: Integer overflow minor fix.
11700 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11701 Define only if GNU_LINUX.
11702 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11704 * dispnew.c: Integer signedness and overflow fixes.
11705 Remove unnecessary forward decls, that were a maintenance hassle.
11706 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11708 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11709 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11710 (prepare_desired_row, line_draw_cost):
11711 Use int, not unsigned, where either works.
11712 (save_current_matrix, restore_current_matrix):
11713 Use ptrdiff_t, not size_t, where either works.
11714 (init_display): Check for overflow more accurately, and without
11715 relying on undefined behavior.
11717 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11718 Remove, replacing with the new symbols in lisp.h. All uses changed.
11719 * fileio.c (make_temp_name):
11720 * filelock.c (lock_file_1, lock_file):
11721 * xdisp.c (message_dolog):
11722 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11723 Use pMd etc. instead.
11724 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11725 replacing the pWIDE etc. symbols removed from editfns.c.
11727 * keyboard.h (num_input_events): Now uintmax_t.
11728 This is (very slightly) less likely to mess up due to wraparound.
11731 * buffer.c: Integer signedness fixes.
11732 (alloc_buffer_text, enlarge_buffer_text):
11733 Use ptrdiff_t rather than size_t when either will do, as we prefer
11736 * alloc.c: Integer signedness and overflow fixes.
11737 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11738 (__malloc_size_t): Default to size_t, not to int.
11739 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11740 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11741 Prefer ptrdiff_t to size_t when either would do, as we prefer
11743 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11744 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11745 Now const. Initialize with values that are in range even if char
11747 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11748 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11749 These functions do the right thing with sizes > 2**32.
11750 (check_depth): Now ptrdiff_t, not int.
11751 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11752 Adjust to new way of storing sizes. Check for size overflow bugs
11754 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11755 slightly wrong anyway, as it missed one instance of
11756 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11757 (refill_memory_reserve): Omit needless cast to size_t.
11758 (mark_object_loop_halt): Mark as externally visible.
11760 * xselect.c: Integer signedness and overflow fixes.
11761 (Fx_register_dnd_atom, x_handle_dnd_message):
11762 Use ptrdiff_t, not size_t, since we prefer signed.
11763 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11764 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11765 x_dnd_atoms_size and x_dnd_atoms_length.
11767 * doprnt.c: Prefer signed to unsigned when either works.
11769 * doprnt.c (doprnt):
11771 * xdisp.c (vmessage):
11772 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11773 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11774 prefer signed arithmetic to avoid comparison confusion.
11775 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11776 but is a bit tricky.
11778 Assume freestanding C89 headers, string.h, stdlib.h.
11779 * data.c, doprnt.c, floatfns.c, print.c:
11780 Include float.h unconditionally.
11781 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11782 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11783 * regex.c: Likewise for stddef.h, string.h.
11784 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11785 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11786 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11787 (STDC_HEADERS): Remove obsolete defines.
11788 * sysdep.c: Include limits.h unconditionally.
11790 Assume support for memcmp, memcpy, memmove, memset.
11791 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11792 * regex.c (memcmp, memcpy):
11793 Remove; we assume C89 now.
11795 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11796 (__malloc_safe_bcopy): Remove; no longer needed.
11798 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11799 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11800 well either way, and we prefer signed to unsigned.
11802 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11804 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11805 closes the connection while we're reading (bug#9182).
11807 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11809 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11810 are specified (Bug#9168).
11812 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11814 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11815 Found by GCC static checking and --with-wide-int on a 32-bit host.
11817 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11819 * xdisp.c (compute_display_string_pos): Fix logic of caching
11820 previous display string position. Initialize cached_prev_pos to
11821 -1. Fixes slow-down at the beginning of a buffer.
11823 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11825 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11826 for attrs[LFACE_FONTSET_INDEX].
11828 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11830 * xml.c (parse_region): Remove unused local
11831 that was recently introduced.
11833 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11835 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11836 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11838 * xdisp.c (move_it_in_display_line_to): Record the best matching
11839 position for TO_CHARPOS while scanning the line, and restore it on
11840 exit if none of the characters scanned was an exact match.
11841 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11842 when exact match is impossible due to invisible text, and the
11843 lines are truncated.
11845 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11847 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11850 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11852 Fix a significant slow-down of cursor motion with C-n, C-p,
11853 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11854 auto-repeat under bidi redisplay in fontified buffers.
11855 * xdisp.c (compute_stop_pos_backwards): New function.
11856 (next_element_from_buffer): Call compute_stop_pos_backwards to
11857 find a suitable prev_stop when we find ourselves before
11859 (reseat): Don't look for prev_stop, as that could mean a very long
11861 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11862 <cached_disp_overlay_modiff>: Cache for last found display string
11864 (compute_display_string_pos): Return the cached position if asked
11865 about the same buffer in the same area of character positions, and
11866 the buffer wasn't changed since the time the display string
11867 position was cached.
11869 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11871 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11872 is an integer, which is important for empty lines. (Bug#9149)
11874 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11876 * frame.c (Fmodify_frame_parameters): In tty case, update the
11877 default face if necessary (Bug#4238).
11879 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11881 * editfns.c (Fstring_to_char): No need to explain what a character
11882 is in the docstring (Bug#6576).
11884 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11886 * xml.c (parse_region): Make sure we always return a tree.
11888 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11890 * xml.c (parse_region): If a document contains only comments,
11893 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11895 * xml.c (make_dom): Return comments, too.
11897 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11900 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11901 and the surrounding thread.
11902 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11903 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11904 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11906 * s/openbsd.h (BROKEN_SIGIO): Define.
11907 * unexelf.c (unexec) [__OpenBSD__]:
11908 Don't update the .mdebug section of the Alpha COFF symbol table.
11910 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11912 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11915 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11917 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11918 This fixes some race conditions on the permissions of any newly
11921 * alloc.c (valid_pointer_p): Use pipe, not open.
11922 This fixes some permissions issues when debugging.
11924 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11925 If fchown fails to set both uid and gid, try to set just gid,
11926 as that is sometimes allowed. Adjust the file's mode to eliminate
11927 setuid or setgid bits that are inappropriate if fchown fails.
11929 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11931 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11932 to compare Lisp_Objects.
11933 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11934 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11935 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11937 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11939 * lread.c (read_integer): Unread even EOF character.
11940 (read1): Likewise. Properly record start position of symbol.
11942 * lread.c (read1): Read `#:' as empty uninterned symbol if no
11943 symbol character follows.
11945 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11947 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11948 This works around a problem with the previous change to Fcopy_file.
11949 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11950 and without this change, GCC might complain about discarding
11951 fchown's return value.
11953 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11955 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11957 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11959 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11961 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11963 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11964 it's used from the C level.
11966 * process.c: Use the same condition for POLL_FOR_INPUT in both
11967 keyboard.c and process.c (bug#1858).
11969 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11971 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11972 (Fgnutls_boot): Use it.
11974 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11976 * doc.c (Fsubstitute_command_keys): Revert last change.
11978 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11980 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11981 quotes the next character, and doesn't affect other longer
11982 sequences (bug#8935).
11984 * lread.c (syms_of_lread): Clarify that is isn't only
11985 `eval-buffer' and `eval-defun' that's affected by
11986 `lexical-binding' (bug#8460).
11988 2011-07-15 Eli Zaretskii <eliz@gnu.org>
11990 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11991 bidi redisplay when a line includes both an image and is truncated.
11993 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11995 Fix minor problems found by static checking.
11996 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11997 (elsz): Now a signed constant, not a size_t var. We prefer signed
11998 types to unsigned, to avoid integer comparison confusion. Without
11999 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
12000 "cannot optimize loop, the loop counter may overflow", a symptom
12002 * indent.c (Fvertical_motion): Mark locals as initialized.
12003 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
12005 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
12007 * search.c (Fre_search_backward): Mention `case-fold-search' in
12008 all the re_search_* functions (bug#8138).
12010 * keyboard.c (Fopen_dribble_file): Document when the file is
12013 2011-07-14 Eli Zaretskii <eliz@gnu.org>
12015 * bidi.c (bidi_dump_cached_states): Fix format of displaying
12018 Support bidi reordering of display and overlay strings.

12021 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
12022 (reseat_to_string): Initialize bidi_it->string.s and
12023 bidi_it->string.schars.
12024 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
12025 NULL (avoids a crash in bidi_paragraph_init).
12026 Initialize itb.string.lstring.
12027 (init_iterator): Call bidi_init_it only of a valid
12028 buffer position was specified. Initialize paragraph_embedding to
12030 (reseat_to_string): Initialize the bidi iterator.
12031 (display_string): If we need to ignore text properties of
12032 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
12033 original value of -1 will not work with bidi.)
12034 (compute_display_string_pos): First arg is now struct
12035 `text_pos *'; all callers changed. Support display properties on
12037 (compute_display_string_end): Support display properties on Lisp
12039 (init_iterator, reseat_1, reseat_to_string): Initialize the
12040 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
12041 when iterating on a string not from display properties).
12042 (compute_display_string_pos, compute_display_string_end):
12043 Fix calculation of the object to scan. Fixes an error when using
12045 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
12046 base_level_stop; instead, set base_level_stop to BEGV.
12047 Fixes crashes in vertical-motion.
12048 (next_element_from_buffer): Improve commentary for when
12049 the iterator is before prev_stop.
12050 (init_iterator): Initialize bidi_p from the default value of
12051 bidi-display-reordering, not from buffer-local value. Use the
12052 buffer-local value only if initializing for buffer iteration.
12053 (handle_invisible_prop): Support invisible properties on strings
12054 that are being bidi-reordered.
12055 (set_iterator_to_next): Support bidi reordering of C strings and
12057 (next_element_from_string): Support bidi reordering of Lisp
12059 (handle_stop_backwards): Support Lisp strings as well.
12060 (display_string): Support display of R2L glyph rows.
12061 Use IT_STRING_CHARPOS when displaying from a Lisp string.
12062 (init_iterator): Don't initialize it->bidi_p for strings
12064 (reseat_to_string): Initialize it->bidi_p for strings here.
12065 (next_element_from_string, next_element_from_c_string)
12066 (next_element_from_buffer): Add xassert's for correspondence
12067 between IT's object being iterated and it->bidi_it.string
12069 (face_before_or_after_it_pos): Support bidi iteration.
12070 (next_element_from_c_string): Handle the case of the first string
12071 character that is not the first one in the visual order.
12072 (get_visually_first_element): New function, refactored from common
12073 parts of next_element_from_buffer, next_element_from_string, and
12074 next_element_from_c_string.
12075 (tool_bar_lines_needed, redisplay_tool_bar)
12076 (display_menu_bar): Force left-to-right direction. Add a FIXME
12077 comment for making that be controlled by a user option.
12078 (push_it, pop_it): Save and restore the state of the
12079 bidi iterator. Save and restore the bidi_p flag.
12080 (pop_it): Iterate out of display property for string iteration as
12082 (iterate_out_of_display_property): Support iteration over strings.
12083 (handle_single_display_spec): Set up it->bidi_it for iteration
12084 over a display string, and call bidi_init_it.
12085 (handle_single_display_spec, next_overlay_string)
12086 (get_overlay_strings_1, push_display_prop): Set up the bidi
12087 iterator for displaying display or overlay strings.
12088 (forward_to_next_line_start): Don't use the shortcut if
12090 (back_to_previous_visible_line_start): If handle_display_prop
12091 pushed the iterator stack, restore the internal state of the bidi
12092 iterator by calling bidi_pop_it same number of times.
12093 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
12094 and we are bidi-iterating, don't decrement the iterator position;
12095 instead, set the first_elt flag in the bidi iterator, to produce
12097 (reseat_1): Remove redundant setting of string_from_display_prop_p.
12098 (push_display_prop): xassert that we are iterating a buffer.
12099 (push_it, pop_it): Save and restore paragraph_embedding member.
12100 (handle_single_display_spec, next_overlay_string)
12101 (get_overlay_strings_1, reseat_1, reseat_to_string)
12102 (push_display_prop): Set up the `unibyte' member of bidi_it.string
12103 correctly. Don't assume unibyte strings are not bidi-reordered.
12104 (compute_display_string_pos)
12105 (compute_display_string_end): Fix handling the case of C string.
12106 (push_it, pop_it): Save and restore from_disp_prop_p.
12107 (handle_single_display_spec, push_display_prop): Set the
12108 from_disp_prop_p flag.
12109 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
12110 (pop_it): Call iterate_out_of_display_property only if we are

12566 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
12568 Random fixes. E.g., (random) never returned negative values.
12569 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
12570 subseconds part to the entropy, as that's a bit more random.
12571 Prefer signed to unsigned, since the signedness doesn't matter and
12572 in general we prefer signed. When given a limit, use a
12573 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12574 latter isn't right if USE_2_TAGS_FOR_INTS.
12575 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12576 not 0..VALMASK. Don't discard "excess" bits that random () returns.
12578 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
12580 * textprop.c (text_property_stickiness):
12581 Obey Vtext_property_default_nonsticky.

12589 This is more efficient than Ffile_directory_p and avoids a minor race.
12591 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
12593 * buffer.c (Foverlay_put): Say what the return value is
12596 * fileio.c (barf_or_query_if_file_exists): Check first if the file
12597 is a directory before asking whether to use the file name
12599 (barf_or_query_if_file_exists): Make the "File is a directory"
12600 error be more correct.
12602 * fns.c (Frequire): Remove the mention of the .gz files, since
12603 that's installation-specific, but keep the mention of
12604 `get-load-suffixes'.
12606 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
12608 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

12613 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
12614 (syms_of_gnutls): Remove duplicate DEFSYM for
12615 Qgnutls_bootprop_verify_hostname_error, an error for
12616 Qgnutls_bootprop_verify_error (which is no longer used).
12618 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
12619 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
12620 Also (re)move comments that are misplaced or no longer relevant.
12622 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12624 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

12652 * fns.c (Frequire): Mention .el.gz files (bug#7314).
12653 (Frequire): Mention get-load-suffixes.

12721 * eval.c (struct backtrace): Simplify and port the data structure.
12722 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12723 signed bit field, as this assumption is not portable and it makes
12724 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12725 "char debug_on_exit : 1" as this is not portable either; instead,
12726 use the portable "unsigned int debug_on_exit : 1". Remove unused
12727 member evalargs. Remove obsolete comments about cc bombing out.
12729 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
12731 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

12797 (emacs_fixed_new): Set priv->f to argument.
12798 (emacs_fixed_get_preferred_width)
12799 (emacs_fixed_get_preferred_height): Use min_width/height from
12800 frames size_hint to set minimum and natural (Bug#8919).
12801 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
12802 and use min_width/height from frames size_hint to set
12803 min_width/height (Bug#8919).

12895 * print.c (printchar, strout): Check for string overflow.
12896 (PRINTPREPARE, printchar, strout):
12897 Don't set size unless allocation succeeds.
12899 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
12900 for sizes. Check for string overflow more accurately.

12914 (read_integer): Radix is now EMACS_INT, not int,
12915 to improve quality of diagnostics for out-of-range radices.
12916 Calculate buffer size correctly for out-of-range radices.
12917 (read1): Check for integer overflow in radices, and in
12918 read-circle numbers.
12919 (read_escape): Avoid int overflow.
12920 (Fload, openp, read_buffer_size, read1)
12921 (substitute_object_recurse, read_vector, read_list, map_obarray):
12922 Use ptrdiff_t, not int, for sizes.

12944 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
12945 The following patches are for when GLYPH_DEBUG && !XASSERT.
12946 * dispextern.h (trace_redisplay_p, dump_glyph_string):
12947 * dispnew.c (flush_stdout):
12948 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
12949 Mark as externally visible.
12950 * dispnew.c (check_window_matrix_pointers): Now static.
12951 * dispnew.c (window_to_frame_vpos):
12952 * xfns.c (unwind_create_frame):
12953 * xterm.c (x_check_font): Remove unused local.
12954 * scroll.c (CHECK_BOUNDS):
12955 * xfaces.c (cache_fache): Rename local to avoid shadowing.
12956 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.

12959 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
12961 (debug_method_add): Use va_list and vsprintf rather than relying
12962 on undefined behavior with wrong number of arguments.
12963 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12964 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12965 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12966 since we're not interested in debugging glyphs with old libraries.
12967 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12968 GCC 4.6.0's static checking.
12970 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

12987 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
12988 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
12989 (.bitmaps_last, struct x_output.icon_bitmap):
12990 Use ptrdiff_t, not int, for bitmap indexes.
12991 (x_allocate_bitmap_record): Check for size overflow.
12992 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
12994 Use ptrdiff_t, not int, for overlay counts.
12995 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
12996 * editfns.c (overlays_around, get_pos_property):
12997 * textprop.c (get_char_property_and_overlay):
12998 * xdisp.c (next_overlay_change, note_mouse_highlight):
12999 * xfaces.c (face_at_buffer_position):
13000 * buffer.c (OVERLAY_COUNT_MAX): New macro.
13001 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
13002 (Fnext_overlay_change, Fprevious_overlay_change)
13003 (mouse_face_overlay_overlaps, Foverlays_in):
13004 Use ptrdiff_t, not int, for sizes.
13005 (overlays_at, overlays_in): Check for size-calculation overflow.
13007 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
13009 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
13010 (x_session_initialize): Do not assume string length fits in int.
13012 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
13013 This is unlikely, but can occur if DPI is outlandish.
13015 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
13016 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
13018 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
13019 * xrdb.c (magic_file_p, search_magic_path):
13020 Omit last arg SUFFIX; it was always 0. All callers changed.
13021 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
13023 * xfont.c (xfont_match): Avoid need for strlen.
13025 * xfns.c: Don't assume strlen fits in int.
13026 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
13028 * xdisp.c (message_log_check_duplicate): Return intmax_t,
13029 not unsigned long, as we prefer signed integers. All callers changed.
13030 Detect integer overflow in repeat count.
13031 (message_dolog): Don't assume print length fits in 39 bytes.
13032 (display_mode_element): Don't assume strlen fits in int.
13034 * termcap.c: Don't assume sizes fit in int and never overflow.
13035 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
13036 (gobble_line): Check for size-calculation overflow.
13038 * minibuf.c (Fread_buffer):
13039 * lread.c (intern, intern_c_string):
13040 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
13041 Don't assume string length fits in int.
13043 * keyboard.c (parse_tool_bar_item):
13044 * gtkutil.c (style_changed_cb): Avoid need for strlen.
13046 * font.c: Don't assume string length fits in int.
13047 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
13048 Use ptrdiff_t, not int.
13049 (font_intern_prop): Don't assume string length fits in int.
13050 Don't assume integer property fits in fixnum.
13051 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
13053 * filelock.c: Fix some buffer overrun and integer overflow issues.
13054 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
13055 Reformulate so as not to need the command string.
13056 Invoke gzip -cd rather than gunzip, as it's more portable.
13057 (lock_info_type, lock_file_1, lock_file):
13058 Don't assume pid_t and time_t fit in unsigned long.
13059 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
13060 (current_lock_owner): Prefer signed type for sizes.
13061 Use memcpy, not strncpy, where memcpy is what is really wanted.
13062 Don't assume (via atoi) that time_t and pid_t fit in int.
13063 Check for time_t and/or pid_t out of range, e.g., via a network share.
13064 Don't alloca where an auto var works fine.
13066 * fileio.c: Fix some integer overflow issues.
13067 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
13068 Don't assume string length fits in int.
13069 (directory_file_name): Don't assume string length fits in long.
13070 (make_temp_name): Don't assume pid fits in int, or that its print
13071 length is less than 20.
13073 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
13075 * coding.c (make_subsidiaries): Don't assume string length fits in int.
13077 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
13079 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
13080 We prefer signed integers, even for size calculations.
13082 * emacs.c: Don't assume string length fits in 'int'.
13083 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
13084 (main): Don't invoke strlen when not needed.
13086 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
13087 (XD_DEBUG_MESSAGE): Don't waste a byte.
13089 * callproc.c (getenv_internal_1, getenv_internal)
13090 (Fgetenv_internal):
13091 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
13093 * lread.c (invalid_syntax): Omit length argument.
13094 All uses changed. This doesn't fix a bug, but it simplifies the
13095 code away from its former Hollerith-constant appearance, and it's
13096 one less 'int' to worry about when looking at integer-overflow issues.
13097 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
13099 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
13100 This didn't break anything, but it didn't help either.
13101 It's confusing to put a bogus integer in a place where the actual
13102 value does not matter.
13103 (LIST_END_P): Remove unused macro and its bogus comment.
13104 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
13106 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
13107 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
13109 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
13110 We prefer signed types, and the value cannot exceed the EMACS_INT
13111 range anyway (because otherwise the length would not be representable).
13112 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
13113 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
13114 This avoids a GCC warning when WIDE_EMACS_INT.
13116 * indent.c (sane_tab_width): New function.
13117 (current_column, scan_for_column, Findent_to, position_indentation)
13118 (compute_motion): Use it. This is just for clarity.
13119 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
13121 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
13123 * lisp.h (lint_assume): New macro.
13124 * composite.c (composition_gstring_put_cache):
13125 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
13127 * editfns.c, insdel.c:
13128 Omit unnecessary forward decls, to simplify future changes.
13130 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
13132 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
13134 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
13135 Use much-faster test for byte-length change.
13136 Don't assume string byte-length fits in 'int'.
13137 Check that character arg fits in 'int'.
13138 (mapcar1): Declare byte as byte, for clarity.
13140 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
13142 * fns.c (concat): Catch string overflow earlier.
13143 Do not rely on integer wraparound.
13145 * dispextern.h (struct it.overlay_strings_charpos)
13146 (struct it.selective): Now EMACS_INT, not int.
13147 * xdisp.c (forward_to_next_line_start)
13148 (back_to_previous_visible_line_start)
13149 (reseat_at_next_visible_line_start, next_element_from_buffer):
13150 Don't arbitrarily truncate the value of 'selective' to int.
13152 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
13154 * composite.c: Don't truncate sizes to 'int'.
13155 (composition_gstring_p, composition_reseat_it)
13156 (composition_adjust_point): Use EMACS_INT, not int.
13157 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
13158 not EMACS_UINT, for indexes.
13160 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
13162 * buffer.c: Include <verify.h>.
13163 (struct sortvec.priority, struct sortstr.priority):
13164 Now EMACS_INT, not int.
13165 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
13166 (struct sortstr.size, record_overlay_string)
13167 (struct sortstrlist.size, struct sortlist.used):
13168 Don't truncate size to int.
13169 (record_overlay_string): Check for size-calculation overflow.
13170 (init_buffer_once): Check at compile-time, not run-time.
13172 2011-06-22 Jim Meyering <meyering@redhat.com>
13174 Don't leak an XBM-image-sized buffer
13175 * image.c (xbm_load): Free the image buffer after using it.
13177 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
13180 * composite.c (find_automatic_composition): Omit needless 'return 0;'
13181 that Sun C diagnosed.
13182 * fns.c (secure_hash): Fix pointer signedness issue.
13183 * intervals.c (static_offset_intervals): New function.
13184 (offset_intervals): Use it.
13186 2011-06-21 Leo Liu <sdl.web@gmail.com>
13189 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
13192 * fns.c (secure_hash): Rename from crypto_hash_function and change
13193 the first arg to accept symbols.
13194 (Fsecure_hash): New primitive.
13195 (syms_of_fns): New symbols.
13197 2011-06-20 Deniz Dogan <deniz@dogan.se>
13199 * process.c (Fset_process_buffer): Clarify return value in
13202 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
13204 * dispnew.c (add_window_display_history): Use BVAR.
13206 * xdisp.c (debug_method_add): Use BVAR.
13207 (check_window_end, dump_glyph_matrix, dump_glyph)
13208 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
13210 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
13213 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
13214 check till after the cache is created in init_frame_faces.
13216 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
13218 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
13220 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
13222 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
13223 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
13224 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
13226 Improve buffer-overflow checking (Bug#8873).
13227 * fileio.c (Finsert_file_contents):
13228 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
13229 Remove the old (too-loose) buffer overflow checks.
13230 They weren't needed, since make_gap checks for buffer overflow.
13231 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
13232 The old code merely checked for Emacs fixnum overflow, and relied
13233 on undefined (wraparound) behavior. The new code avoids undefined
13234 behavior, and also checks for ptrdiff_t and/or size_t overflow.
13236 * editfns.c (Finsert_char): Don't dump core with very negative counts.
13237 Tune. Don't use wider integers than needed. Don't use alloca.
13238 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
13240 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
13242 * insdel.c, lisp.h (buffer_overflow): New function.
13243 (insert_from_buffer_1, replace_range, replace_range_2):
13244 * insdel.c (make_gap_larger):
13245 * editfns.c (Finsert_char):
13246 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
13248 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
13250 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
13252 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
13254 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
13255 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
13257 * fileio.c: Don't assume EMACS_INT fits in off_t.
13258 (emacs_lseek): New static function.
13259 (Finsert_file_contents, Fwrite_region): Use it.
13260 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
13262 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
13264 * fns.c: Don't overflow int when computing a list length.
13265 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
13266 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
13267 truncation on 64-bit hosts. Check for QUIT every
13268 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
13269 faster and is responsive enough.
13270 (Flength): Report an error instead of overflowing an integer.
13271 (Fsafe_length): Return a float if the value is not representable
13272 as a fixnum. This shouldn't happen except in contrived situations.
13273 (Fnthcdr, Fsort): Don't assume list length fits in int.
13274 (Fcopy_sequence): Don't assume vector length fits in int.
13276 * alloc.c: Check that resized vectors' lengths fit in fixnums.
13277 (header_size, word_size): New constants.
13278 (allocate_vectorlike): Don't check size overflow here.
13279 (allocate_vector): Check it here instead, since this is the only
13280 caller of allocate_vectorlike that could cause overflow.
13281 Check that the new vector's length is representable as a fixnum.
13283 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
13284 The previous code was bogus. For example, next_almost_prime (32)
13285 returned 39, which is undesirable as it is a multiple of 3; and
13286 next_almost_prime (24) returned 25, which is a multiple of 5 so
13287 why was the code bothering to check for multiples of 7?
13289 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
13291 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
13293 Variadic C functions now count arguments with ptrdiff_t.
13294 This partly undoes my 2011-03-30 change, which replaced int with size_t.
13295 Back then I didn't know that the Emacs coding style prefers signed int.
13296 Also, in the meantime I found a few more instances where arguments
13297 were being counted with int, which may truncate counts on 64-bit
13298 machines, or EMACS_INT, which may be unnecessarily wide.
13299 * lisp.h (struct Lisp_Subr.function.aMANY)
13300 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
13301 Arg counts are now ptrdiff_t, not size_t.
13302 All variadic functions and their callers changed accordingly.
13303 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
13304 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
13305 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
13306 * callint.c (Fcall_interactively): Check arg count for overflow,
13307 to avoid potential buffer overrun. Use signed char, not 'int',
13308 for 'varies' array, so that we needn't bother to check its size
13309 calculation for overflow.
13310 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
13311 * eval.c (apply_lambda):
13312 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
13313 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
13314 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
13316 * callint.c (Fcall_interactively): Don't use index var as event count.
13318 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
13319 * mem-limits.h (SIZE): Remove; no longer used.
13321 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
13323 Remove unnecessary casts.
13324 * xterm.c (x_term_init):
13325 * xfns.c (x_set_border_pixel):
13326 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
13327 These aren't needed now that we assume ANSI C.
13329 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
13330 It's more likely to cause problems (due to unsigned overflow)
13333 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
13335 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
13337 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
13339 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
13341 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
13343 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
13345 GLYPH_CODE_FACE returns EMACS_INT, not int.
13346 * dispextern.h (merge_faces):
13347 * xfaces.c (merge_faces):
13348 * xdisp.c (get_next_display_element, next_element_from_display_vector):
13349 Don't assume EMACS_INT fits in int.
13351 * character.h (CHAR_VALID_P): Remove unused parameter.
13352 * fontset.c, lisp.h, xdisp.c: All uses changed.
13354 * editfns.c (Ftranslate_region_internal): Omit redundant test.
13356 * fns.c (concat): Minor tuning based on overflow analysis.
13357 This doesn't fix any bugs. Use int to hold character, instead
13358 of constantly refetching from Emacs object. Use XFASTINT, not
13359 XINT, for value known to be a character. Don't bother comparing
13360 a single byte to 0400, as it's always less.
13362 * floatfns.c (Fexpt):
13363 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
13365 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
13368 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
13370 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
13371 Without this fix, on a 64-bit host (aset S 0 4294967386) would
13372 incorrectly succeed when S was a string, because 4294967386 was
13373 truncated before it was used.
13375 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13376 Otherwise, an out-of-range integer could cause undefined behavior
13379 * composite.c: Use int, not EMACS_INT, for characters.
13380 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13381 EMACS_INT, for values that are known to be in character range.
13382 This doesn't fix any bugs but is the usual style inside Emacs and
13383 may generate better code on 32-bit machines.
13385 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13386 This is for reasons similar to the recent CHAR_STRING fix.
13387 * charset.c (Fencode_char): Check that character arg is actually
13388 a character. Pass an int to ENCODE_CHAR.
13389 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13390 wider than 'int', as a compile-time check to prevent future regressions
13393 * character.c (char_string): Remove unnecessary casts.
13395 Make sure a 64-bit char is never passed to CHAR_STRING.
13396 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13397 by silently ignoring the top 32 bits, allowing some values
13398 that were far too large to be valid characters.
13399 * character.h: Include <verify.h>.
13400 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13401 arguments are no wider than unsigned, as a compile-time check
13402 to prevent future regressions in this area.
13404 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
13405 (Fsubst_char_in_region):
13407 * xdisp.c (decode_mode_spec_coding):
13408 Adjust to CHAR_STRING's new requirement.
13409 * editfns.c (Finsert_char, Fsubst_char_in_region):
13410 * fns.c (concat): Check that character args are actually
13411 characters. Without this test, these functions did the wrong
13412 thing with wildly out-of-range values on 64-bit hosts.
13414 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13415 These casts should not be needed on 32-bit hosts, either.
13416 * keyboard.c (read_char):
13417 * lread.c (Fload): Remove casts to unsigned.
13419 * lisp.h (UNSIGNED_CMP): New macro.
13420 This fixes comparison bugs on 64-bit hosts.
13421 (ASCII_CHAR_P): Use it.
13422 * casefiddle.c (casify_object):
13423 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
13424 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
13425 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
13426 * dispextern.h (FACE_FROM_ID):
13427 * keyboard.c (read_char): Use UNSIGNED_CMP.
13429 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,

13477 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13478 when a (possibly-narrower) signed value would do just as well.
13479 We prefer using signed arithmetic, to avoid comparison confusion.
13481 * alloc.c: Catch some string size overflows that we were missing.
13482 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
13483 for convenience in STRING_BYTES_MAX.
13484 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
13485 The definition here is exact; the one in lisp.h was approximate.
13486 (allocate_string_data): Check for string overflow. This catches
13487 some instances we weren't catching before. Also, it catches
13488 size_t overflow on (unusual) hosts where SIZE_MAX <= min
13489 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
13490 and ptrdiff_t and EMACS_INT are both 64 bits.
13492 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
13493 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.

14071 instead of using explicit *_CHAR codes.
14072 (bidi_resolve_explicit, bidi_resolve_weak):

14081 (bidi_level_of_next_char): Don't try to lookup the cache for the
14082 next/previous character if nothing is cached there yet, or if we
14083 were just reseat()'ed to a new position.
14085 * xdisp.c (set_cursor_from_row): Set start and stop points
14086 according to the row's direction when priming the loop that looks
14087 for the glyph on which to display cursor.

14089 (display_prop_intangible_p): Reimplement to call
14090 handle_display_spec instead of single_display_spec_intangible_p.
14091 Accept 3 additional arguments needed by handle_display_spec.
14092 This fixes incorrect cursor motion across display property with complex
14093 values: lists, `(when COND...)' forms, etc.

14095 lists with the argument STRING its top-level element.
14096 (display_prop_string_p): Fix the condition for processing a

14101 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
14102 value of a `display' property is a "replacing spec".
14103 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
14104 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
14105 the display property, but just return a value indicating whether
14106 the display property will replace the characters it covers.
14107 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
14108 frame_window_p members of struct bidi_it.

14132 All callers changed. (Bug#8762)
14134 * gnutls.c: Use Emacs's memory allocators.
14135 Without this change, the gnutls library would invoke malloc etc.
14136 directly, which causes problems on non-SYNC_INPUT hosts, and which
14137 runs afoul of improving memory_full behavior. (Bug#8761)
14138 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
14139 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
14140 xfree instead of the default malloc, realloc, free.
14141 (Fgnutls_boot): No need to check for memory allocation failure,
14142 since xmalloc does that for us.

14164 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
14165 for hashes and hash indexes, instead of 'unsigned' and 'int'.
14166 * alloc.c (allocate_vectorlike):
14167 Check for overflow in vector size calculations.
14168 * ccl.c (ccl_driver):
14169 Check for overflow when converting EMACS_INT to int.

14171 need to be updated by these changes.
14172 * fns.c (make_hash_table, maybe_resize_hash_table):
14173 Check for integer overflow with large hash tables.
14174 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
14175 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
14176 (SXHASH_REDUCE): New macro.
14177 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
14178 Use it instead of discarding useful hash info with large hash values.
14179 (sxhash_float): New function.
14180 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
14181 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
14182 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
14183 Rewrite to use FIXNUM_BITS, as this simplifies things.
14184 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
14185 Adjust signatures to match updated version of code.
14186 (consing_since_gc): Now EMACS_INT, since a single hash table can
14187 use more than INT_MAX bytes.

14236 Make it possible to run ./temacs.
14238 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
14239 syms_of_callproc does the same thing. Remove test for

14301 (crypto_hash_function): Use it to convert some newly-signed
14302 variables to unsigned, to avoid sign-extension bugs. For example,
14303 without this change, (md5 "truc") would evaluate to
14304 45723a2aff78ff4fff7fff1114760e62 rather than the expected
14305 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
14306 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
14308 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14310 Integer overflow fixes.
14312 * dbusbind.c: Serial number integer overflow fixes.
14313 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
14314 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
14315 to hold a serial number that is too large for a fixnum.
14316 (Fdbus_method_return_internal, Fdbus_method_error_internal):
14317 Check for serial numbers out of range. Decode any serial number
14318 that was so large that it became a float. (Bug#8722)
14320 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
14321 (Fdbus_call_method, Fdbus_call_method_asynchronously):
14322 Use XFASTINT rather than XUINT when numbers are nonnegative.
14323 (xd_append_arg, Fdbus_method_return_internal):
14324 (Fdbus_method_error_internal): Likewise. Also, for unsigned
14325 arguments, check that Lisp number is nonnegative, rather than
14326 silently wrapping negative numbers around. (Bug#8722)
14327 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
14330 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
14332 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
14334 ccl: Add integer overflow checks.
14335 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
14336 (IN_INT_RANGE): New macros.
14337 (ccl_driver): Use them to check for integer overflow when
14338 decoding a CCL program. Many of the new checks are whether XINT (x)
14339 fits in int; it doesn't always, on 64-bit hosts. The new version
14340 doesn't catch all possible integer overflows, but it's an
14341 improvement. (Bug#8719)
14343 * alloc.c (make_event_array): Use XINT, not XUINT.
14344 There's no need for unsigned here.
14346 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
14347 This follows up to the 2011-05-06 change that substituted uintptr_t
14348 for EMACS_INT. This case wasn't caught back then.
14350 Rework Fformat to avoid integer overflow issues.
14351 * editfns.c: Include <float.h> unconditionally, as it's everywhere
14352 now (part of C89). Include <verify.h>.
14353 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
14354 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
14355 (Fformat): Avoid the prepass trying to compute sizes; it was only
14356 approximate and thus did not catch overflow reliably. Instead, walk
14357 through the format just once, formatting and computing sizes as we go,
14358 checking for integer overflow at every step, and allocating a larger
14359 buffer as needed. Keep track separately whether the format is
14360 multibyte. Keep only the most-recently calculated precision, rather
14361 than them all. Record whether each argument has been converted to
14362 string. Use EMACS_INT, not int, for byte and char and arg counts.
14363 Support field widths and precisions larger than INT_MAX. Avoid
14364 sprintf's undefined behavior with conversion specifications such as %#d
14365 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
14366 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
14367 formatting out-of-range floating point numbers with int
14368 formats. (Bug#8668)
14370 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
14372 * data.c: Avoid integer truncation in expressions involving floats.
14373 * data.c: Include <intprops.h>.
14374 (arith_driver): When there's an integer overflow in an expression
14375 involving floating point, convert the integers to floating point
14376 so that the resulting value does not suffer from catastrophic
14377 integer truncation. For example, on a 64-bit host (* 4
14378 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14379 Do not rely on undefined behavior after integer overflow.
14381 merge count_size_as_multibyte, parse_str_to_multibyte
14382 * character.c, character.h (count_size_as_multibyte):
14383 Rename from parse_str_to_multibyte; all uses changed.
14384 Check for integer overflow.
14385 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14386 since it's now a duplicate of the other. This is more of
14387 a character than a buffer op, so better that it's in character.c.
14388 * fns.c, print.c: Adjust to above changes.
14390 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14392 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14394 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14396 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14397 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14398 (x_clipboard_manager_save): Now static.
14399 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14401 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14402 (crypto_hash_function): Now static.
14403 Fix pointer signedness problems. Avoid unnecessary initializations.
14405 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14407 * termhooks.h (Vselection_alist): Make it terminal-local.
14409 * terminal.c (create_terminal): Initialize it.
14411 * xselect.c: Support for clipboard managers.
14412 (Vselection_alist): Move to termhooks.h as terminal-local var.
14413 (LOCAL_SELECTION): New macro.
14414 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14415 (symbol_to_x_atom): Remove gratuitous arg.
14416 (x_handle_selection_request, lisp_data_to_selection_data)
14417 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14418 (x_own_selection, x_get_local_selection, x_convert_selection):
14419 New arg, specifying work frame. Use terminal-local Vselection_alist.
14420 (some_frame_on_display): Delete unused function.
14421 (Fx_own_selection_internal, Fx_get_selection_internal)
14422 (Fx_disown_selection_internal, Fx_selection_owner_p)
14423 (Fx_selection_exists_p): New optional frame arg.
14424 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14425 (x_handle_selection_clear): Don't treat other terminals with the
14426 same keyboard specially. Use the terminal-local Vselection_alist.
14427 (x_clear_frame_selections): Use Frun_hook_with_args.
14429 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14431 * xterm.h: Add support for those atoms.
14433 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14435 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14436 (converted_selections, conversion_fail_tag): New global variables.
14437 (x_selection_request_lisp_error): Free the above.
14438 (x_get_local_selection): Remove unnecessary code.
14439 (x_reply_selection_request): Args changed; handle arbitrary array
14440 of converted selections stored in converted_selections.
14441 Separate the XChangeProperty and SelectionNotify steps.
14442 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14443 (x_convert_selection): New function.
14444 (x_handle_selection_event): Simplify.
14445 (x_get_foreign_selection): Don't ignore incoming requests while
14446 waiting for an answer; this will fail when we implement
14447 SAVE_TARGETS, and seems unnecessary anyway.
14448 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14449 (Vx_sent_selection_functions): Doc fix.
14451 2011-05-26 Leo Liu <sdl.web@gmail.com>
14453 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14455 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14457 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14459 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14460 for fringe update if it has periodic bitmap.
14461 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14462 and fringe_bitmap_periodic_p.
14464 * fringe.c (get_fringe_bitmap_data): New function.
14465 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14466 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14467 row. Mark glyph row for fringe update if periodicity changed.
14469 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14470 for fringe update unless it has periodic bitmap.
14472 2011-05-25 Kenichi Handa <handa@m17n.org>
14474 * xdisp.c (get_next_display_element): Set correct it->face_id for
14475 a static composition.
14477 2011-05-24 Leo Liu <sdl.web@gmail.com>
14480 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
14482 * fns.c (crypto_hash_function, Fsha1): New function.
14483 (Fmd5): Use crypto_hash_function.
14484 (syms_of_fns): Add Ssha1.
14486 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14488 * gnutls.c: Remove unused macros.
14489 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14490 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14491 Remove macros that are defined and never used.
14492 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14494 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14496 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14497 (Fx_get_selection_internal): Minor cleanup.
14498 (Fx_own_selection_internal): Rename arguments for consistency with
14501 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14503 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
14505 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14507 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
14509 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14511 * dispnew.c (scrolling_window): Don't exclude the case that the
14512 last enabled row in the desired matrix touches the bottom boundary.
14514 2011-05-21 Glenn Morris <rgm@gnu.org>
14516 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
14517 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
14518 and add some more files.
14520 2011-05-20 Eli Zaretskii <eliz@gnu.org>
14522 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
14523 report_file_error introduced by the change from 2011-05-07.
14525 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14527 * systime.h (Time): Define only if emacs is defined.
14528 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14529 where the include path doesn't have X11/X.h by default. See
14530 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14532 2011-05-20 Kenichi Handa <handa@m17n.org>
14534 * composite.c (find_automatic_composition): Fix previous change.
14536 2011-05-20 Glenn Morris <rgm@gnu.org>
14538 * lisp.mk: New file, split from Makefile.in.
14539 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14540 (shortlisp): Remove.
14541 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14543 2011-05-19 Glenn Morris <rgm@gnu.org>
14545 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14546 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14547 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14548 (lisp): Set the order to that of loadup.el.
14549 (shortlisp): Make it a copy of $lisp.
14550 (SOME_MACHINE_LISP): Remove.
14551 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14552 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14554 2011-05-18 Kenichi Handa <handa@m17n.org>
14556 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14557 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14558 (find_automatic_composition): Mostly rewrite for efficiency.
14560 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14562 * makefile.w32-in: Update dependencies.
14564 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14566 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14567 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14569 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14571 Fix some integer overflow issues, such as string length overflow.
14573 * insdel.c (count_size_as_multibyte): Check for string overflow.
14575 * character.c (lisp_string_width): Check for string overflow.
14576 Use EMACS_INT, not int, for string indexes and lengths; in
14577 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14578 the resulting string length overflows an EMACS_INT; instead,
14579 report a string overflow if no precision given. When checking for
14580 precision exhaustion, use a check that cannot possibly have
14581 integer overflow. (Bug#8675)
14582 * character.h (lisp_string_width): Adjust to new signature.
14584 * alloc.c (string_overflow): New function.
14585 (Fmake_string): Use it. This doesn't change behavior, but saves
14586 a few bytes and will simplify future changes.
14587 * character.c (string_escape_byte8): Likewise.
14588 * lisp.h (string_overflow): New decl.
14590 Fixups, following up to the user-interface timestamp change.
14591 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14592 for UI timestamps, instead of unsigned long.
14593 * msdos.c (mouse_get_pos): Likewise.
14594 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14595 * w32gui.h (Time): Define by including "systime.h" rather than by
14596 declaring it ourselves. (Bug#8664)
14598 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14599 * image.c (clear_image_cache): Likewise.
14601 * term.c (term_mouse_position): Don't assume time_t wraparound.
14603 Be more systematic about user-interface timestamps.
14604 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14605 and sometimes 'EMACS_UINT', to represent these timestamps.
14606 This change causes it to use 'Time' uniformly, as that's what X uses.
14607 This makes the code easier to follow, and makes it easier to catch
14608 integer overflow bugs such as Bug#8664.
14609 * frame.c (Fmouse_position, Fmouse_pixel_position):
14610 Use Time, not unsigned long, for user-interface timestamps.
14611 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14612 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14613 * keyboard.h (last_event_timestamp): Likewise.
14614 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14615 * menu.h (xmenu_show): Likewise.
14616 * term.c (term_mouse_position): Likewise.
14617 * termhooks.h (struct input_event.timestamp): Likewise.
14618 (struct terminal.mouse_position_hook): Likewise.
14619 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14620 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14621 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14622 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14623 what it was before.
14624 * menu.h, termhooks.h: Include "systime.h", for Time.
14626 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14627 Don't assume that the difference between two unsigned long values
14628 can fit into an integer. At this point, we know button_down_time
14629 <= event->timestamp, so the difference must be nonnegative, so
14630 there's no need to cast the result if double-click-time is
14631 nonnegative, as it should be; check that it's nonnegative, just in
14632 case. This bug is triggered when events are more than 2**31 ms
14633 apart (about 25 days). (Bug#8664)
14635 * xselect.c (last_event_timestamp): Remove duplicate decl.
14636 (x_own_selection): Remove needless cast to unsigned long.
14638 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14639 that always fit in int. Use a sentinel instead of a counter, to
14640 avoid a temp and to allay GCC's concerns about possible int overflow.
14641 * frame.h (struct frame): Use int for menu_bar_items_used
14642 instead of EMACS_INT, since it always fits in int.
14644 * menu.c (grow_menu_items): Check for int overflow.
14646 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14648 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14649 Before, the code was not consistent. These values cannot exceed
14650 2**31 - 1 so there's no need to make them unsigned.
14651 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14652 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14653 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14655 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14657 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14658 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14659 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14660 presumably because the widths might not match.
14662 * window.c (size_window): Avoid needless test at loop start.
14664 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14666 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14668 2011-05-12 Drew Adams <drew.adams@oracle.com>
14670 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14672 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14674 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14675 `width' to `bar_area_x' and `bar_area_width', respectively.
14676 (x_scroll_run): Take account of fringe background extension.
14678 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14679 Rename local vars `left' and `width' to `bar_area_x' and
14680 `bar_area_width', respectively.
14681 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14682 background extension.
14684 2011-05-10 Jim Meyering <meyering@redhat.com>
14686 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14688 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14690 * image.c (Finit_image_library): Return t for built-in image types,
14691 like pbm and xbm. (Bug#8640)
14693 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14695 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14697 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14699 * w32console.c (Fset_screen_color): Doc fix.
14700 (Fget_screen_color): New function.
14701 (syms_of_ntterm): Defsubr it.
14703 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14704 unlink the temporary file if Fcall_process didn't create it in the
14706 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14707 child process will be redirected to a file specified with `:file'.
14708 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14709 cue to call_process_cleanup not to close that handle.
14711 2011-05-07 Ben Key <bkey76@gmail.com>
14713 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14714 one of two shell specific rules, either bootstrap-temacs-CMD or
14715 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14716 to the previous implementation of the bootstrap-temacs rule.
14717 The bootstrap-temacs-CMD rule is similar to the previous
14718 implementation of the bootstrap-temacs rule except that it
14719 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14722 These changes, along with some changes to nt/configure.bat,
14723 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14724 earlier fix to add support for --cflags and --ldflags options
14725 that include quotes so that it works whether make uses cmd or
14728 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14730 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14731 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14733 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14734 a string. Handle both cases.
14735 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14736 (Fdbus_register_method): Use Qinvalid_function.
14738 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14740 * makefile.w32-in: Update dependencies.
14741 (LISP_H): Add inttypes.h and stdin.h.
14742 (PROCESS_H): Add unistd.h.
14744 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14746 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14747 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14749 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14751 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14753 * term.c (vfatal): Remove stray call to va_end.
14754 It's not needed and the C Standard doesn't allow it here anyway.
14756 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14757 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14759 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14762 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14764 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14766 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14768 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14770 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14772 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14773 * charset.c (Fdefine_charset_internal): Don't initialize
14774 charset.code_space[15]. The value was garbage, on hosts with
14775 32-bit int (Bug#8600).
14777 * lread.c (read_integer): Be more consistent with string-to-number.
14778 Use string_to_number to do the actual conversion; this avoids
14779 rounding errors and fixes some other screwups. Without this fix,
14780 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14781 (digit_to_number): Move earlier, for benefit of read_integer.
14782 Return -1 if the digit is out of range for the base, -2 if it is
14783 not a digit in any supported base. (Bug#8602)
14785 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14787 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14788 to match comment at start of function. This also removes a
14789 GCC warning about overflow in a 32+64-bit port.
14791 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14793 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14794 Reported by Stefan Monnier in
14795 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14796 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14797 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14799 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14800 (EMACS_UINTPTR): Likewise, with uintptr_t.
14802 * lisp.h: Prefer 64-bit EMACS_INT if available.
14803 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14804 on 32-bit hosts that have 64-bit int, so that they can access
14806 However, temporarily disable this change unless the temporary
14807 symbol WIDE_EMACS_INT is defined.
14809 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14811 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14812 This removes an assumption that EMACS_INT and long are the same
14813 width as pointers. The assumption is true for Emacs porting targets
14814 now, but we want to make other targets possible.
14815 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14816 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14817 In the rest of the code, change types of integers that hold casted
14818 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14819 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14820 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14821 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14822 No need to cast type when ORing.
14823 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14824 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14825 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14826 assume EMACS_INT is the same width as char *.
14827 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14828 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14829 Remove no-longer-needed casts.
14830 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14831 (xg_tool_bar_help_callback, xg_make_tool_item):
14832 Use EMACS_INTPTR to hold an integer
14833 that will be cast to void *; this can avoid a GCC warning
14834 if EMACS_INT is not the same width as void *.
14835 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14836 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14837 (current_message_1, set_message_1):
14838 Use a local to convert to proper width without a cast.
14839 * xmenu.c (dialog_selection_callback): Likewise.
14841 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14842 Also, don't assume VALBITS / RAND_BITS is less than 5,
14843 and don't rely on undefined behavior when shifting a 1 left into
14845 * lisp.h (get_random): Change signature to match.
14847 * lread.c (hash_string): Use size_t, not int, for hash computation.
14848 Normally we prefer signed values; but hashing is special, because
14849 it's better to use unsigned division on hash table sizes so that
14850 the remainder is nonnegative. Also, size_t is the natural width
14851 for hashing into memory. The previous code used 'int', which doesn't
14852 retain enough info to hash well into very large tables.
14853 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14855 * dbusbind.c: Don't possibly lose pointer info when converting.
14856 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14857 Use XPNTR rather than XHASH, so that the high-order bits of
14858 the pointer aren't lost when converting through void *.
14860 * eval.c (Fautoload): Don't double-shift a pointer.
14862 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14864 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14866 * gnutls.c (DEF_GNUTLS_FN):
14867 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14869 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14871 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14874 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14876 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14877 New version that can reserve upto 2GB of heap space.
14879 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14881 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14883 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14885 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14886 `gnutls_certificate_set_x509_key_file'.
14888 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
14890 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
14891 Update dependencies.
14893 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14895 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14896 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14897 Remove unused parameter `fildes'.
14898 * process.c (read_process_output, send_process): Don't pass it.
14900 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14902 Fix previous change: the library cache is defined in w32.c.
14903 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14904 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14906 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14908 Implement dynamic loading of GnuTLS on Windows.
14910 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14911 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14912 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14915 * gnutls.c (Qgnutls_dll): Define.
14916 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
14917 (gnutls_*): Declare function pointers.
14918 (init_gnutls_functions): New function to initialize function pointers.

14921 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14922 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
14923 (emacs_gnutls_write, emacs_gnutls_read)
14924 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14925 (Fgnutls_available_p): New function.
14926 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

14939 (w32_delayed_load): Move from image.c. When loading a library, record
14940 its filename in the :loaded-from property of the library id.
14941 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
14942 Initialize and staticpro them.
14943 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
14945 * process.c: Include lisp.h before w32.h, not after.
14946 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
14947 instead of gnutls_record_check_pending.
14949 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
14951 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
14953 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
14954 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
14957 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
14959 * xterm.c (x_set_frame_alpha): Do not set property on anything
14960 else than FRAME_X_OUTER_WINDOW (Bug#8608).
14962 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14964 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
14966 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14968 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

14982 * sysdep.c (wait_for_termination_1): Make static.
14983 (wait_for_termination, interruptible_wait_for_termination):
14984 Move after wait_for_termination_1.
14986 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
14988 * sysdep.c (interruptible_wait_for_termination): New function
14989 which is like wait_for_termination, but allows keyboard
14992 * callproc.c (Fcall_process): Add (:file "file") as an option for
14994 (Fcall_process_region): Ditto.
14996 2011-04-30 Eli Zaretskii <eliz@gnu.org>
14998 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
14999 rather than `XVECTOR (FOO)->size'.
15001 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
15002 inttypes.h, as a gnulib replacement is used if it not available in
15005 2011-04-21 Eli Zaretskii <eliz@gnu.org>
15007 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
15008 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
15009 of MOST_POSITIVE_FIXNUM. (Bug#8528)
15011 * coding.c (coding_alloc_by_realloc): Error out if destination
15012 will grow beyond MOST_POSITIVE_FIXNUM.
15013 (decode_coding_emacs_mule): Abort if there isn't enough place in
15014 charbuf for the composition carryover bytes. Reserve an extra
15015 space for up to 2 characters produced in a loop.
15016 (decode_coding_iso_2022): Abort if there isn't enough place in
15017 charbuf for the composition carryover bytes.
15019 2011-04-21 Eli Zaretskii <eliz@gnu.org>

15024 %llo or %llx format is passed. (Bug#8545)
15026 * window.c (window_scroll_line_based): Use a marker instead of
15027 simple variables to record original value of point. (Bug#7952)
15029 * doprnt.c (doprnt): Fix the case where a multibyte sequence
15030 produced by %s or %c overflows available buffer space. (Bug#8545)
15032 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
15034 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

15067 2011-04-27 Eli Zaretskii <eliz@gnu.org>
15069 Improve `doprnt' and its usage. (Bug#8545)
15070 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
15071 `format_end'. Remove support for %l as a conversion specifier.
15072 Don't use xrealloc. Improve diagnostics when the %l size modifier
15073 is used. Update the commentary.
15075 * eval.c (verror): Simplify calculation of size_t.
15077 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
15080 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
15082 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
15085 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15087 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
15088 This makes this file independent of the recent pseudovector change.
15090 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
15092 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
15094 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
15095 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
15096 Remove unused local.
15097 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
15099 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
15100 GCC 4.6.0 optimizes based on type-based alias analysis.
15101 For example, if b is of type struct buffer * and v of type struct
15102 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
15103 != &v->size, and therefore "v->size = 1; b->size = 2; return
15104 v->size;" must therefore return 1. This assumption is incorrect
15105 for Emacs, since it type-puns struct Lisp_Vector * with many other
15106 types. To fix this problem, this patch adds a new type struct
15107 vectorlike_header that documents the constraints on layout of vectors
15108 and pseudovectors, and helps optimizing compilers not get fooled
15109 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
15110 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
15111 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
15113 (XSETPVECTYPE): Rewrite in terms of new macro.
15114 (XSETPVECTYPESIZE): New macro, specifying both type and size.
15115 This is a bit clearer, and further avoids the possibility of
15116 undesirable aliasing.
15117 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
15118 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
15119 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
15120 since Lisp_Subr is a special case (no "next" field).
15121 (ASIZE): Now uses header.size rather than size.
15122 All previous uses of XVECTOR (foo)->size replaced to use this macro,
15123 to avoid the hassle of writing XVECTOR (foo)->header.size.
15124 (struct vectorlike_header): New type.
15125 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
15126 object, to help avoid aliasing.
15127 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
15128 (SUBRP): Likewise, since Lisp_Subr is a special case.
15129 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
15130 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
15131 (struct Lisp_Hash_Table): Combine first two members into a single
15132 struct vectorlike_header member. All uses of "size" and "next" members
15133 changed to be "header.size" and "header.next".
15134 * buffer.h (struct buffer): Likewise.
15135 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
15136 * frame.h (struct frame): Likewise.
15137 * process.h (struct Lisp_Process): Likewise.
15138 * termhooks.h (struct terminal): Likewise.
15139 * window.c (struct save_window_data, struct saved_window): Likewise.
15140 * window.h (struct window): Likewise.
15141 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
15142 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
15143 * buffer.c (init_buffer_once): Likewise.
15144 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
15146 * process.c (Fformat_network_address): Use local var for size,
15149 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
15151 Make the Lisp reader and string-to-float more consistent (Bug#8525)
15152 * data.c (atof): Remove decl; no longer used or needed.
15153 (digit_to_number): Move to lread.c.
15154 (Fstring_to_number): Use new string_to_number function, to be
15155 consistent with how the Lisp reader treats infinities and NaNs.
15156 Do not assume that floating-point numbers represent EMACS_INT
15157 without losing information; this is not true on most 64-bit hosts.
15158 Avoid double-rounding errors, by insisting on integers when
15159 parsing non-base-10 numbers, as the documentation specifies.
15160 * lisp.h (string_to_number): New decl, replacing ...
15161 (isfloat_string): Remove.
15162 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
15163 (read1): Do not accept +. and -. as integers; this
15164 appears to have been a coding error. Similarly, do not accept
15165 strings like +-1e0 as floating point numbers. Do not report
15166 overflow for integer overflows unless the base is not 10 which
15167 means we have no simple and reliable way to continue.
15168 Break out the floating-point parsing into a new
15169 function string_to_number, so that Fstring_to_number parses
15170 floating point numbers consistently with the Lisp reader.
15171 (digit_to_number): Move here from data.c. Make it static inline.
15172 (E_CHAR, EXP_INT): Remove, replacing with ...
15173 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
15174 (string_to_number): New function, replacing isfloat_string.
15175 This function checks for valid syntax and produces the resulting
15176 Lisp float number too. Rework it so that string-to-number
15177 no longer mishandles examples like "1.0e+". Use strtoumax,
15178 so that overflow for non-base-10 numbers is reported only when
15179 there's no portable and simple way to convert to floating point.
15181 * textprop.c (set_text_properties_1): Rewrite for clarity,
15182 and to avoid GCC warning about integer overflow.
15184 * intervals.h (struct interval): Use EMACS_INT for members
15185 where EMACS_UINT might cause problems. See
15186 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
15187 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
15188 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
15190 (offset_intervals): Tell GCC not to worry about length overflow
15191 when negating a negative length.
15193 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
15194 (overrun_check_free): Likewise.
15196 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
15197 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
15200 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15201 (gnutls_make_error): Rename local to avoid shadowing.
15202 (gnutls_emacs_global_deinit): ifdef out; not used.
15203 (Fgnutls_boot): Use const for pointer to readonly storage.
15204 Comment out unused local. Fix pointer signedness problems.
15206 * lread.c (openp): Don't stuff size_t into an 'int'.
15207 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
15208 about possible signed overflow.
15210 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15211 (GDK_KEY_g): Don't define if already defined.
15212 (xg_prepare_tooltip): Avoid pointer signedness problem.
15213 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
15215 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
15216 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
15218 * xfns.c (Fx_window_property): Simplify a bit,
15219 to make a bit faster and to avoid GCC 4.6.0 warning.
15220 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
15222 * fns.c (internal_equal): Don't assume size_t fits in int.
15224 * alloc.c (compact_small_strings): Tighten assertion a little.
15226 Replace pEd with more-general pI, and fix some printf arg casts.
15227 * lisp.h (pI): New macro, generalizing old pEd macro to other
15228 conversion specifiers. For example, use "...%"pI"d..." rather
15229 than "...%"pEd"...".
15230 (pEd): Remove. All uses replaced with similar uses of pI.
15231 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
15232 * alloc.c (check_pure_size): Don't overflow by converting size to int.
15233 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
15234 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
15235 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
15236 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
15237 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
15239 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
15240 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
15241 * print.c (safe_debug_print, print_object): Likewise.
15242 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
15244 Use pI instead of if-then-else-abort. Use %p to avoid casts,
15245 avoiding the 0 flag, which is not portable.
15246 * process.c (Fmake_network_process): Use pI to avoid cast.
15247 * region-cache.c (pp_cache): Likewise.
15248 * xdisp.c (decode_mode_spec): Likewise.
15249 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
15250 behavior on 64-bit hosts with printf arg.
15251 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
15252 (x_stop_queuing_selection_requests): Likewise.
15253 (x_get_window_property): Don't truncate byte count to an 'int'
15256 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
15257 here, since it parses constructs like leading '-' and spaces,
15258 which are not wanted; and it overflows with large numbers.
15259 Instead, simply match F[0-9]+, which is what is wanted anyway.
15261 * alloc.c: Remove unportable assumptions about struct layout.
15262 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
15263 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
15264 (allocate_vectorlike, make_pure_vector): Use the new macros,
15265 plus offsetof, to remove unportable assumptions about struct layout.
15266 These assumptions hold on all porting targets that I know of, but
15267 they are not guaranteed, they're easy to remove, and removing them
15268 makes further changes easier.
15270 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
15271 This doesn't fix a bug but makes the code clearer.
15272 (string_overrun_cookie): Now const. Use initializers that
15273 don't formally overflow signed char, to avoid warnings.
15274 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
15275 can cause Emacs to crash when string overrun checking is enabled.
15276 (allocate_buffer): Don't assume sizeof (struct buffer) is a
15277 multiple of sizeof (EMACS_INT); it need not be, if
15278 alignof(EMACS_INT) < sizeof (EMACS_INT).
15279 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
15281 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

15288 supposed to be handshaking. (Bug#8556)
15289 Reported by Paul Eggert <eggert@cs.ucla.edu>.
15291 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

15308 2011-04-25 Eli Zaretskii <eliz@gnu.org>
15310 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
15311 "cast to pointer from integer of different size".
15313 Improve doprnt and its use in verror. (Bug#8545)
15314 * doprnt.c (doprnt): Document the set of format control sequences
15315 supported by the function. Use SAFE_ALLOCA instead of always
15318 * eval.c (verror): Don't limit the buffer size at size_max-1, that
15319 is one byte too soon. Don't use xrealloc; instead xfree and
15322 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
15324 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
15327 * gnutls.c: Renamed global_initialized to
15328 gnutls_global_initialized. Added internals for the
15329 :verify-hostname-error, :verify-error, and :verify-flags
15330 parameters of `gnutls-boot' and documented those parameters in the
15331 docstring. Start callback support.
15332 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
15333 unless a fatal error occurred. Call gnutls_alert_send_appropriate

15407 (SIZE_MAX): New macro.
15408 (doprnt): Return a size_t value. 2nd arg is now size_t.
15409 Many local variables are now size_t instead of int or unsigned.
15410 Improve overflow protection. Support `l' modifier for integer
15411 conversions. Support %l conversion. Don't assume an EMACS_INT
15412 argument for integer conversions and for %c.
15414 * lisp.h (doprnt): Restore prototype.
15416 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
15417 $(SRC)/character.h.
15419 * Makefile.in (base_obj): Add back doprnt.o.
15421 * deps.mk (doprnt.o): Add back prerequisites.
15422 (callint.o): Depend on character.h.
15424 * eval.c (internal_lisp_condition_case): Include the handler
15425 representation in the error message.

15431 * callint.c (Fcall_interactively): When displaying error message
15432 about invalid control letter, pass the character's codepoint, not
15433 a pointer to its multibyte form. Improve display of the character
15434 in octal and display also its hex code.
15436 * character.c (char_string): Use %x to display the (unsigned)
15437 codepoint of an invalid character, to avoid displaying a bogus
15440 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15441 `error', not SYMBOL_NAME itself.
15443 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
15444 character arguments to `error'.
15446 * charset.c (check_iso_charset_parameter): Fix incorrect argument
15447 to `error' in error message about FINAL_CHAR argument. Make sure
15448 FINAL_CHAR is a character, and use %c when it is passed as

15515 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
15516 by pacifying GCC about it. Maybe it's time to retire it?
15517 * xfaces.c (USG, __TIMEVAL__): Likewise.
15519 * dispextern.h (struct redisplay_interface): Rename param
15520 to avoid shadowing.
15521 * termhooks.h (struct terminal): Likewise.
15522 * xterm.c (xembed_send_message): Likewise.
15524 * insdel.c (make_gap_smaller): Define only if
15525 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
15527 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
15530 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
15531 so that we aren't warned about unused symbols.
15533 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
15535 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

15544 define if USE_GTK || USE_X_TOOLKIT.
15545 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
15546 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.

15548 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
15550 * xmenu.c (menu_help_callback): Pointer type fixes.

15568 compatible char. Avoid the old compiler warnings about
15569 out-of-range initializers by using, for example, '\xab' rather
15572 * xgselect.c (xgselect_initialize): Check vs interface
15573 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

15638 * nsfont.m: Fixed bugs in ns_get_family and
15639 ns_descriptor_to_entity that were caused by using free to
15640 deallocate memory blocks that were allocated by xmalloc (via
15641 xstrdup). This caused Emacs to crash when compiled with
15642 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
15643 --enable-checking=xmallocoverrun). xfree is now used to
15644 deallocate these memory blocks.

16043 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
16044 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
16045 Remove decls of unexported vars.
16046 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
16048 * lisp.h (DEFINE_FUNC): Make sname 'static'.
16050 Make Emacs functions such as Fatom 'static' by default.
16051 This makes it easier for human readers (and static analyzers)
16052 to see whether these functions can be called from other modules.
16053 DEFUN now defines a static function. To make the function external
16054 so that it can be used in other C modules, use the new macro DEFUE.
16055 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
16056 (Finit_image_library):
16057 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
16058 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
16059 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
16060 Remove decls, since these functions are now static.
16061 (Funintern, Fget_internal_run_time): New decls, since these functions
16062 were already external.
16064 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
16065 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
16066 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
16067 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
16068 * keyboard.c, keymap.c, lread.c:
16069 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
16070 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
16071 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
16072 Mark functions with DEFUE instead of DEFUN,
16073 if they are used in other modules.
16074 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
16075 decls for now-static functions.
16076 * buffer.h (Fdelete_overlay): Remove decl.
16077 * callproc.c (Fgetenv_internal): Mark as internal.
16078 * composite.c (Fremove_list_of_text_properties): Remove decl.
16079 (Fcomposition_get_gstring): New forward static decl.
16080 * composite.h (Fcomposite_get_gstring): Remove decl.
16081 * dired.c (Ffile_attributes): New forward static decl.
16082 * doc.c (Fdocumntation_property): New forward static decl.
16083 * eval.c (Ffetch_bytecode): New forward static decl.
16084 (Funintern): Remove extern decl; now in .h file where it belongs.
16085 * fileio.c (Fmake_symbolic_link): New forward static decl.
16086 * image.c (Finit_image_library): New forward static decl.
16087 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
16088 * intervals.h (Fprevious_property_change):
16089 (Fremove_list_of_text_properties): Remove decls.
16090 * keyboard.c (Fthis_command_keys): Remove decl.
16091 (Fcommand_execute): New forward static decl.
16092 * keymap.c (Flookup_key): New forward static decl.
16093 (Fcopy_keymap): Now static.
16094 * keymap.h (Flookup_key): Remove decl.
16095 * process.c (Fget_process): New forward static decl.
16096 (Fprocess_datagram_address): Mark as internal.
16097 * syntax.c (Fsyntax_table_p): New forward static decl.
16098 (skip_chars): Remove duplicate decl.
16099 * textprop.c (Fprevious_property_change): New forward static decl.
16100 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
16102 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
16103 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
16105 * editfns.c (Fformat): Remove unreachable code.
16107 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
16109 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
16112 2011-04-13 Eli Zaretskii <eliz@gnu.org>
16114 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
16115 when at ZV. (Bug#8487)
16117 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
16119 * charset.c (Fclear_charset_maps): Use xfree instead of free.
16121 * keyboard.c (parse_tool_bar_item): Likewise.
16122 * sound.c (sound_cleanup, alsa_close): Likewise.
16123 * termcap.c (tgetent): Likewise.
16124 * xfns.c (x_default_font_parameter): Likewise.
16125 * xsettings.c (read_and_apply_settings): Likewise.
16127 * alloc.c (overrun_check_malloc, overrun_check_realloc)
16128 (overrun_check_free): Protoize.
16130 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
16132 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
16133 since callers should never pass a negative size.
16134 Change the signature to match that of plain 'read' and 'write'; see
16135 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
16136 * lisp.h: Update prototypes of emacs_write and emacs_read.
16138 2011-04-11 Eli Zaretskii <eliz@gnu.org>
16140 * xdisp.c (redisplay_window): Don't try to determine the character
16141 position of the scroll margin if the window start point w->startp
16142 is outside the buffer's accessible region. (Bug#8468)
16144 2011-04-10 Eli Zaretskii <eliz@gnu.org>
16146 Fix write-region and its subroutines for buffers > 2GB.
16147 * fileio.c (a_write, e_write): Modify declaration of arguments and
16148 local variables to support buffers larger than 2GB.
16149 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
16151 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
16152 argument, local variables, and return value.
16154 * lisp.h: Update prototypes of emacs_write and emacs_read.
16156 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
16158 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
16160 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
16162 Fix more problems found by GCC 4.6.0's static checks.
16164 * xdisp.c (vmessage): Use a better test for character truncation.
16166 * charset.c (load_charset_map): <, not <=, for optimization,
16167 and to avoid potential problems with integer overflow.
16168 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
16169 * casetab.c (set_identity, shuffle): Likewise.
16170 * editfns.c (Fformat): Likewise.
16171 * syntax.c (skip_chars): Likewise.
16173 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
16174 This also lets GCC 4.6.0 generate slightly better loop code.
16176 * callint.c (Fcall_interactively): <, not <=, for optimization.
16177 (Fcall_interactively): Count the number of arguments produced,
16178 not the number of arguments given. This is simpler and lets GCC
16179 4.6.0 generate slightly better code.
16181 * ftfont.c: Distingish more carefully between FcChar8 and char.
16182 The previous code passed unsigned char * to a functions like
16183 strlen and xstrcasecmp that expect char *, which does not
16184 conform to the C standard.
16185 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
16186 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
16187 char * when the C standard requires it.
16189 * keyboard.c (read_char): Remove unused var.
16191 * eval.c: Port to Windows vsnprintf (Bug#8435).
16192 Include <limits.h>.
16193 (SIZE_MAX): Define if the headers do not.
16194 (verror): Do not give up if vsnprintf returns a negative count.
16195 Instead, grow the buffer. This ports to Windows vsnprintf, which
16196 does not conform to C99. Problem reported by Eli Zaretskii.
16197 Also, simplify the allocation scheme, by avoiding the need for
16198 calling realloc, and removing the ALLOCATED variable.
16200 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
16202 Remove invocations of doprnt, as Emacs now uses vsnprintf.
16203 But keep the doprint source code for now, as we might revamp it
16204 and use it again (Bug#8435).
16205 * lisp.h (doprnt): Remove.
16206 * Makefile.in (base_obj): Remove doprnt.o.
16207 * deps.mk (doprnt.o): Remove.
16209 error: Print 32- and 64-bit integers portably (Bug#8435).
16210 Without this change, on typical 64-bit hosts error ("...%d...", N)
16211 was used to print both 32- and 64-bit integers N, which relied on
16212 undefined behavior.
16213 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
16214 * lisp.h (error, verror): Mark as printf-like functions.
16215 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
16216 Report overflow in size calculations when allocating printf buffer.
16217 Do not truncate output string at its first null byte.
16218 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
16219 Truncate the output at a character boundary, since vsnprintf does not
16221 * charset.c (check_iso_charset_parameter): Convert internal
16222 character to string before calling 'error', since %c now has the
16224 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
16225 overflow when computing char to be passed to 'error'. Do not
16226 pass Lisp_Object to 'error'; pass the integer instead.
16227 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
16228 formatted with plain %d.
16230 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
16232 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
16234 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
16236 * xterm.c (x_catch_errors): Remove duplicate declaration.
16238 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
16240 * xdisp.c, lisp.h (message_nolog): Remove; unused.
16242 2011-04-10 Jim Meyering <meyering@redhat.com>
16244 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
16245 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
16246 return ssize_t not "int", and use size_t as the buffer length.
16247 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
16248 * gnutls.h: Update declarations.
16249 * process.c (read_process_output): Use ssize_t, to match.
16250 (send_process): Likewise.
16252 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16254 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
16256 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16258 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
16259 Use unsigned char, to match FcChar8 type definition.
16261 * xterm.c (handle_one_xevent):
16262 * xmenu.c (create_and_show_popup_menu):
16263 * xselect.c (x_decline_selection_request)
16264 (x_reply_selection_request): Avoid type-punned deref of X events.
16266 2011-04-09 Eli Zaretskii <eliz@gnu.org>
16268 Fix some uses of `int' instead of EMACS_INT.
16269 * search.c (string_match_1, fast_string_match)
16270 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
16271 (scan_buffer, find_next_newline_no_quit)
16272 (find_before_next_newline, search_command, Freplace_match)
16273 (Fmatch_data): Make some `int' variables be EMACS_INT.
16275 * xdisp.c (display_count_lines): 3rd argument and return value now
16276 EMACS_INT. All callers changed.
16277 (pint2hrstr): Last argument is now EMACS_INT.
16279 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
16280 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
16281 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
16282 (decode_coding_utf_16, decode_coding_emacs_mule)
16283 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
16284 (decode_coding_ccl, decode_coding_charset)
16285 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
16286 (decode_coding_iso_2022, decode_coding_emacs_mule)
16287 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
16288 <char_offset, last_offset>: Declare EMACS_INT.

16290 (encode_coding_emacs_mule, encode_invocation_designation)
16291 (encode_designation_at_bol, encode_coding_iso_2022)
16292 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
16293 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
16295 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
16296 (encode_invocation_designation): Last argument P_NCHARS is now
16298 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
16299 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
16301 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
16304 * ccl.c (Fccl_execute_on_string): Declare some variables
16307 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
16309 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
16311 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
16313 * process.c (Fformat_network_address): Doc fix.
16315 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
16317 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
16319 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
16321 * keyboard.c (read_char): Call Lisp function help-form-show,
16322 instead of using internal_with_output_to_temp_buffer.
16323 (Qhelp_form_show): New var.
16324 (syms_of_keyboard): Use DEFSYM macro.
16326 * print.c (internal_with_output_to_temp_buffer): Function deleted.

16333 (list_processes_1): Delete.
16335 2011-04-06 Eli Zaretskii <eliz@gnu.org>
16337 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
16339 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
16341 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
16343 Fix more problems found by GCC 4.6.0's static checks.

16349 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
16351 * xdisp.c (vmessage): Mark as a printf-like function.
16353 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
16355 * sound.c (sound_warning): Don't crash if arg contains a printf format.

16360 to system-supplied API.
16362 * eval.c (Fsignal): Remove excess argument to 'fatal'.
16364 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
16365 This avoids several warnings with gcc -Wstrict-overflow.
16366 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
16367 directly, rather than having caller test rule sign. This avoids
16368 some unnecessary tests.
16369 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
16370 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
16371 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
16373 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16374 (xfont_open): Avoid unnecessary tests.
16376 * composite.c (composition_gstring_put_cache): Use unsigned integer.

16385 by using the new macro.
16387 * textprop.c (set_text_properties_1): Change while to do-while,
16388 since the condition is always true at first.
16390 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16391 (interval_deletion_adjustment): Return unsigned value.
16394 * process.c (list_processes_1, create_pty, read_process_output):

16407 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
16408 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
16410 * print.c (print_error_message): Avoid int overflow.
16412 * font.c (font_list_entities): Redo for clarity,
16413 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
16415 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
16416 (font_score): Avoid potential overflow in diff calculation.
16418 * fns.c (substring_both): Remove var that is set but not used.
16419 (sxhash): Redo loop for clarity and to avoid wraparound warning.
16421 * eval.c (funcall_lambda): Rename local to avoid shadowing.
16423 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
16424 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
16425 can always succeed if overflow has undefined behavior.
16427 * search.c (boyer_moore, wordify): Remove vars set but not used.
16428 (wordify): Omit three unnecessary tests.
16430 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
16431 All callers changed. This avoids the need for an unused var.
16433 * casefiddle.c (casify_region): Remove var that is set but not used.
16435 * dired.c (file_name_completion): Remove var that is set but not used.

16439 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16440 (Finsert_file_contents): Remove unnecessary code checking fd.
16442 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
16443 Check for integer overflow on size calculations.
16445 * buffer.c (Fprevious_overlay_change): Remove var that is set
16448 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16449 Remove vars that are set but not used.
16450 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16451 (timer_check_2): Mark vars as initialized.
16453 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16455 * image.c (lookup_image): Remove var that is set but not used.
16456 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16458 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16459 that are set but not used.
16461 * xfns.c (make_invisible_cursor): Don't return garbage
16462 if XCreateBitmapFromData fails (Bug#8410).
16464 * xselect.c (x_get_local_selection, x_handle_property_notify):
16465 Remove vars that are set but not used.
16467 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
16468 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
16470 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
16471 Remove var that is set but not used.

16473 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16474 Check for overflow.
16476 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16477 (map_tty_color) [!defined MSDOS]: Likewise.
16479 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16481 * coding.c: Remove vars that are set but not used.
16482 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
16483 All callers changed.
16484 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):

16489 that is set but not used.
16491 * print.c (print_object): Remove var that is set but not used.
16493 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16494 The gnulib version avoids calling malloc in the usual case,
16495 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16496 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16497 * filelock.c (current_lock_owner): Likewise.
16498 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16499 * sysdep.c: Include allocator.h, careadlinkat.h.
16500 (emacs_no_realloc_allocator): New static constant.
16501 (emacs_readlink): New function.
16502 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16503 ../lib/careadlinkat.h.
16505 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
16507 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

16529 do not dereference NULL upon failed strdup
16530 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16531 (ns_get_family): Likewise.
16533 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16535 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16537 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16539 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16542 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16544 Add lexical binding.
16546 * window.c (Ftemp_output_buffer_show): New fun.
16547 (Fsave_window_excursion):
16548 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.

16553 Bind Qinternal_interpreter_environment.
16554 (Feval_buffer): Bind Qlexical_binding.
16555 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16557 (syms_of_lread): Declare `lexical-binding'.
16559 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16561 * keyboard.c (eval_dyn): New fun.
16562 (menu_item_eval_property): Use it.
16564 * image.c (parse_image_spec): Use Ffunctionp.
16566 * fns.c (concat, mapcar1): Accept byte-code-functions.
16568 * eval.c (Fsetq): Handle lexical vars.
16569 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16570 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16571 (FletX, Flet): Obey lexical binding.
16572 (Fcommandp): Handle closures.
16573 (Feval): New `lexical' arg.
16574 (eval_sub): New function extracted from Feval. Use it almost
16575 everywhere where Feval was used. Look up vars in lexical env.
16577 (Ffunctionp): Move from subr.el.
16578 (Ffuncall): Handle closures.
16579 (apply_lambda): Remove `eval_flags'.
16580 (funcall_lambda): Handle closures and new byte-code-functions.
16581 (Fspecial_variable_p): New function.
16582 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16583 but without exporting it to Lisp.
16585 * doc.c (Fdocumentation, store_function_docstring):
16586 * data.c (Finteractive_form): Handle closures.
16588 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16591 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16593 (exec_byte_code): New function extracted from Fbyte_code to handle new
16594 calling convention for byte-code-functions. Add new byte-codes.
16596 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

16602 * xdisp.c (redisplay_internal): Fix prototype.
16604 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16606 * xdisp.c (SCROLL_LIMIT): New macro.
16607 (try_scrolling): Use it when setting scroll_limit.
16608 Limit scrolling to 100 screen lines.
16609 (redisplay_window): Even when falling back on "recentering",
16610 position point in the window according to scroll-conservatively,
16611 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16613 (try_scrolling): When point is above the window, allow searching
16614 as far as scroll_max, or one screenful, to compute vertical
16615 distance from PT to the scroll margin position. This prevents
16616 try_scrolling from unnecessarily failing when
16617 scroll-conservatively is set to a value slightly larger than the
16618 window height. Clean up the case of PT below the margin at bottom
16619 of window: scroll_max can no longer be INT_MAX. When aggressive
16620 scrolling is in use, don't let point enter the opposite scroll
16621 margin as result of the scroll.
16622 (syms_of_xdisp) <scroll-conservatively>: Document the
16623 threshold of 100 lines for never-recentering scrolling.

16630 (message_log_check_duplicate): Remove parameters `prev_bol' and
16631 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16632 (redisplay_internal): Remove parameter `preserve_echo_area',
16633 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16635 * indent.c (Fvertical_motion):
16636 * window.c (window_scroll_pixel_based, Frecenter):
16637 Don't pass `need_y_p' to `move_it_by_lines'.
16639 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16641 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16642 steal a few bits to be more compact.
16643 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16644 Remove unneeded casts.
16646 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16648 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16650 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16651 binding" message (bug#7967).
16653 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16655 Fix more problems found by GCC 4.6.0's static checks.
16657 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16658 Remove unused local var.
16660 * editfns.c (Fmessage_box): Remove unused local var.
16662 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16663 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16664 Omit unused local vars.
16665 * window.c (shrink_windows): Omit unused local var.
16666 * menu.c (digest_single_submenu): Omit unused local var.
16667 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16668 Omit unused local var.
16670 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16671 Don't assume string length fits in int.
16672 (keyremap_step, read_key_sequence): Use size_t for sizes.
16673 (read_key_sequence): Don't check last_real_key_start redundantly.
16675 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
16676 instead of alloca (Bug#8344).
16678 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16679 (Fbacktrace_frame): Don't assume nframes fits in int.
16681 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

16688 * cm.c (calccost): Turn while-do into do-while, for clarity.
16690 * keyboard.c (syms_of_keyboard): Use the same style as later
16691 in this function when indexing through an array. This also
16692 works around GCC bug 48267.
16694 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16696 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16698 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16699 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16701 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16702 This avoids undefined behavior on integer overflow, and is a bit
16703 more convenient anyway since it is compared to a size_t variable.
16705 Variadic C functions now count arguments with size_t, not int.
16706 This avoids an unnecessary limitation on 64-bit machines, which
16707 caused (substring ...) to crash on large vectors (Bug#8344).

16717 * fns.c (concat): Likewise.
16718 * frame.c (x_set_frame_parameters): Likewise.
16719 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16720 0 if not found, not -1. All callers changed.
16722 * alloc.c (garbage_collect): Don't assume stack size fits in int.
16723 (stack_copy_size): Now size_t, not int.
16724 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

16745 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
16746 don't set the hook to nil, but remove the offending function instead.
16747 (Qcommand_hook_internal): Remove, unused.
16748 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
16749 Vcommand_hook_internal.
16751 * eval.c (enum run_hooks_condition): Remove.
16752 (funcall_nil, funcall_not): New functions.
16753 (run_hook_with_args): Call each function through a `funcall' argument.

16767 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.

16929 * buffer.c (Fkill_all_local_variables):
16930 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
16932 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
16933 unconditionally since it does the check itself.
16935 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
16937 Fix more problems found by GCC 4.5.2's static checks.
16939 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16940 the first time through the loop, since we know p0 < p1 then.
16941 This also avoids a gcc -Wstrict-overflow warning.
16943 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16944 leading to a memory leak, possible in functions like
16945 load_charset_map_from_file that can allocate an unbounded number
16946 of objects (Bug#8318).
16948 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16949 that could (at least in theory) be that large.
16951 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16952 This is less likely to overflow, and avoids undefined behavior if
16953 overflow does occur. All callers changed. Use strtoul to scan
16954 for the unsigned long integer.
16955 (pint2hrstr): Simplify and tune code slightly.
16956 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
16958 * scroll.c (do_scrolling): Work around GCC bug 48228.
16959 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
16961 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
16962 This also avoids a warning with gcc -Wstrict-overflow.
16963 (validate_x_resource_name): Simplify count usage.
16964 This also avoids a warning with gcc -Wstrict-overflow.
16966 * fileio.c (Fcopy_file): Report error if fchown or fchmod
16969 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
16971 * process.c (Fmake_network_process): Use socklen_t, not int,
16972 where POSIX says socklen_t is required in portable programs.
16973 This fixes a porting bug on hosts like 64-bit HP-UX, where
16974 socklen_t is wider than int (Bug#8277).
16975 (Fmake_network_process, server_accept_connection):
16976 (wait_reading_process_output, read_process_output):
16979 * process.c: Rename or move locals to avoid shadowing.

16989 Make tparam.h and terminfo.c consistent.
16990 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
16991 Include tparam.h instead, since it declares them.
16992 * cm.h (PC): Remove extern decl; tparam.h now does this.
16993 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
16994 * terminfo.c: Include tparam.h, to check interfaces.
16995 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
16996 (tparam): Adjust signature to match interface in tparam.h;
16997 this removes some undefined behavior. Check that outstring and len
16998 are zero, which they always are with Emacs.
16999 * tparam.h (PC, BC, UP): New extern decls.
17001 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
17002 (xftfont_open): Rename locals to avoid shadowing.
17004 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
17005 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
17006 (OTF_TAG_SYM): Omit macro if not needed.

17014 * xml.c (make_dom): Now static.
17016 * composite.c (composition_compute_stop_pos): Rename local to
17018 (composition_reseat_it): Remove unused locals.
17019 (find_automatic_composition, composition_adjust_point): Likewise.
17020 (composition_update_it): Mark var as initialized.
17021 (find_automatic_composition): Mark vars as initialized,
17022 with a FIXME (Bug#8290).

17025 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
17026 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
17027 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
17028 (BUF_DEC_POS): Be more systematic about renaming local temporaries
17029 to avoid shadowing.
17031 * textprop.c (property_change_between_p): Remove; unused.
17033 * intervals.c (interval_start_pos): Now static.
17035 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

17038 Rename locals to avoid shadowing.
17040 * sound.c (wav_play, au_play, Fplay_sound_internal):
17041 Fix pointer signedness.
17042 (alsa_choose_format): Remove unused local var.
17043 (wav_play): Initialize a variable to 0, to prevent undefined
17044 behavior (Bug#8278).
17046 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
17048 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
17050 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
17051 clobbering (Bug#8298).
17052 * sysdep.c (sys_subshell): Likewise.
17053 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
17055 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
17056 This should get cleaned up, so that child_setup has the
17057 same signature on all platforms.
17059 * callproc.c (call_process_cleanup): Now static.
17060 (relocate_fd): Rename locals to avoid shadowing.
17062 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
17064 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
17065 not to be necessary, and produces flickering.
17067 2011-03-20 Glenn Morris <rgm@gnu.org>
17069 * config.in: Remove file.
17071 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
17073 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
17074 are now in src/globals.h.
17075 (syms_of_minibuf): Remove spurious & from previous change.
17077 2011-03-20 Leo Liu <sdl.web@gmail.com>
17079 * minibuf.c (completing-read-function): New variable.
17080 (completing-read-default): Rename from completing-read.
17081 (completing-read): Call completing-read-function.
17083 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
17085 * xfaces.c (Fx_load_color_file):
17086 Read color file from absolute filename (bug#8250).
17088 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
17090 * makefile.w32-in: Update dependencies.
17092 2011-03-17 Eli Zaretskii <eliz@gnu.org>
17094 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

17101 (sigchld_handler): Now static.
17103 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
17104 That way, the code declares only the vars that it needs.

17114 (CONSTANTLIM): Remove; unused.
17115 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
17116 Define only if needed.
17118 * unexelf.c (unexec): Name an expression,
17119 to avoid gcc -Wbad-function-cast warning.
17120 Use a different way to cause a compilation error if anyone uses
17121 n rather than nn, a way that does not involve shadowing.
17122 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
17124 * deps.mk (unexalpha.o): Remove; unused.
17126 New file unexec.h, the (simple) interface for unexec (Bug#8267).
17127 * unexec.h: New file.
17128 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
17129 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
17130 Depend on unexec.h.
17131 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
17132 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
17133 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
17134 Change as necessary to match prototype in unexec.h.
17136 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

17152 instead of using an uninitialized var.
17153 (font_sort_entities): Mark var as initialized.
17155 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
17157 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

17182 (Fcall_interactively): Rename locals to avoid shadowing.
17183 Use const pointer when appropriate.

17189 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
17190 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
17191 some of which prompt warnings from gcc -Wbad-function-cast.
17192 (Fformat_time_string, Fencode_time, Finsert_char):
17193 (Ftranslate_region_internal, Fformat):
17194 Rename or remove local vars to avoid shadowing.
17195 (Ftranslate_region_internal): Mark var as initialized.
17197 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
17200 * lisp.h (eassert): Check that the argument compiles, even if
17201 ENABLE_CHECKING is not defined.
17203 * data.c (Findirect_variable): Name an expression, to avoid
17204 gcc -Wbad-function-cast warning.
17205 (default_value, arithcompare, arith_driver, arith_error): Now static.

17213 Rename locals to avoid shadowing.
17214 (mark_stack): Move local variables into the #ifdef region where
17216 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
17217 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
17219 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
17220 (GC_STRING_CHARS): Remove; not used.
17221 (Fmemory_limit): Cast sbrk's returned value to char *.
17223 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
17224 avoids undefined behavior in theory.
17226 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
17228 Use functions, not macros, for up- and down-casing (Bug#8254).
17229 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17230 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
17231 to use the following functions instead of these macros.
17232 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
17233 EMACS_INT, since callers assume the returned value fits in int.
17234 (upcase1): Likewise, for UPCASE_TABLE.
17235 (uppercasep, lowercasep, upcase): New static inline functions.
17236 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
17237 the race-condition problem in the old DOWNCASE.
17239 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):

17241 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
17242 (regex_compile, re_search_2, re_match_2_internal):
17243 Remove unused local vars.
17244 (FREE_VAR): Rewrite so as not to use empty "else",
17245 which gcc can warn about.
17246 (regex_compile, re_match_2_internal): Mark locals as initialized.
17247 (RETALLOC_IF): Define only if needed.
17248 (WORDCHAR_P): Likewise. This one is never needed, but is used
17249 only in a comment talking about a compiler bug, so put inside
17250 the #if 0 of that comment.
17251 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
17252 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
17255 * search.c (boyer_moore): Rename locals to avoid shadowing.
17256 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

17267 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
17269 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
17270 Rename locals to avoid shadowing.
17271 (Fvertical_motion): Mark locals as initialized.
17273 * casefiddle.c (casify_object, casify_region): Now static.
17274 (casify_region): Mark local as initialized.
17276 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
17278 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
17279 New macros, so that the caller can use some names other than
17280 gcpro1, gcpro2, etc.
17281 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
17283 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
17284 argument, for consistency with GCPRO2_VAR, etc: it is now the
17285 prefix of the variable, not the variable itself. All uses
17287 * dired.c (directory_files_internal, file_name_completion):
17288 Rename locals to avoid shadowing.
17290 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
17291 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
17292 dired.c's scmp function, had undefined behavior.
17293 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17294 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
17295 * buffer.h: ... to here, because these macros use current_buffer,
17296 and the new implementation with inline functions needs to have
17297 current_buffer in scope now, rather than later when the macros
17299 (downcase, upcase1): New static inline functions.
17300 (DOWNCASE, UPCASE1): Reimplement using these functions.
17301 This avoids undefined behavior in expressions like
17302 DOWNCASE (x) == DOWNCASE (y), which previously suffered
17303 from race conditions in accessing the global variables
17304 case_temp1 and case_temp2.
17305 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
17306 * lisp.h (case_temp1, case_temp2): Remove their decls.
17307 * character.h (ASCII_CHAR_P): Move from here ...
17308 * lisp.h: ... to here, so that the inline functions mentioned
17309 above can use them.
17311 * dired.c (directory_files_internal_unwind): Now static.
17313 * fileio.c (file_name_as_directory, directory_file_name):
17314 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
17316 (file_name_as_directory): Use const pointers when appropriate.
17317 (Fexpand_file_name): Likewise. In particular, newdir might
17318 point at constant storage, so make it a const pointer.
17319 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
17320 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
17322 (Fset_file_times, Finsert_file_contents, auto_save_error):
17323 Rename locals to avoid shadowing.
17325 * minibuf.c (choose_minibuf_frame_1): Now static.
17326 (Ftry_completion, Fall_completions): Rename or remove locals
17327 to avoid shadowing.
17329 * marker.c (bytepos_to_charpos): Remove; unused.
17331 * lisp.h (verify_bytepos, count_markers): New decls,
17332 so that gcc does not warn that these functions aren't declared.
17334 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
17335 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
17336 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
17337 (copy_text): Remove unused local var.
17339 * filelock.c (within_one_second): Now static.
17340 (lock_file_1): Rename local to avoid shadowing.
17342 * buffer.c (fix_overlays_before): Mark locals as initialized.
17343 (fix_start_end_in_overlays): Likewise. This function should be
17344 simplified by using pointers-to-pointers, but that's a different
17346 (switch_to_buffer_1): Now static.
17347 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
17348 (report_overlay_modification): Rename locals to avoid shadowing.
17350 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
17351 Fix pointer signedness issue.
17352 (sys_subshell): Mark local as volatile if checking for lint,
17353 to suppress a gcc -Wclobbered warning that does not seem to be right.
17354 (MAXPATHLEN): Define only if needed.
17356 * process.c (serial_open, serial_configure): Move decls from here ...
17357 * systty.h: ... to here, so that they can be checked.
17359 * fns.c (get_random, seed_random): Move extern decls from here ...
17360 * lisp.h: ... to here, so that they can be checked.
17362 * sysdep.c (reset_io): Now static.
17363 (wait_for_termination_signal): Remove; unused.
17365 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
17366 (copy_keymap_item, append_key, push_text_char_description):
17368 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
17369 (DENSE_TABLE_SIZE): Remove; unused.
17370 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
17371 (describe_map_tree):
