45 Move pid_t related decls out of lisp.h.
46 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
47 (interruptible_wait_for_termination):
48 Move these decls from lisp.h to syswait.h, since they use pid_t.
49 Needed on FreeBSD; see Herbert J. Skuhra in
50 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
51 * callproc.c: Include syswait.h.

97 2012-09-23 Eli Zaretskii <eliz@gnu.org>
99 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
100 fatal_error_backtrace.
102 * w32proc.c (sys_kill): Undo last change: don't do anything when
103 invoked to deliver SIGABRT to our own process. This is now
104 handled by emacs_raise.
106 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
108 * w32term.c (w32_read_socket): Remove leftover reference to
109 interrupt_input_pending.
111 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
113 Do not use SA_NODEFER.
114 Problem reported by Dani Moncayo in
115 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
117 * sysdep.c (emacs_abort): Do not reset signal handler.
118 * emacs.c (terminate_due_to_signal): Reset signal handler here.
119 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
120 wanted even on POSIXish hosts, and it doesn't work on Windows.
122 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
124 * xterm.c (x_term_init): Call fixup_locale before and after calling
125 gtk_init (Bug#12392).
127 2012-09-23 Chong Yidong <cyd@gnu.org>
129 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
130 Vdynamic_library_alist.
132 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
133 (Fgnutls_available_p): Caller changed.
135 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)

142 (init_xpm_functions, init_png_functions, init_jpeg_functions)
143 (init_tiff_functions, init_gif_functions, init_svg_functions):
144 Arglist and w32_delayed_load calling convention changed.
145 (gs_type): Remove init_gs_functions; there is no such function.
146 (valid_image_p, make_image): Fix caller to lookup_image_type.
148 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
150 Simplify and avoid signal-handling races (Bug#12471).
152 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
153 Avoid recursive loop if there's a fatal error in the function itself.
154 * atimer.c (pending_atimers):
155 * blockinput.h: Don't include "atimer.h"; no longer needed.
156 (interrupt_input_pending): Remove. All uses removed.
157 pending_signals now counts both atimers and ordinary interrupts.
158 This is less racy than having three separate pending-signal flags.
159 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
161 Rename from their upper-case counterparts BLOCK_INPUT,
162 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
163 INPUT_BLOCKED_P, and turn into functions. All uses changed.
164 This makes it easier to access volatile variables more accurately.
165 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
166 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
167 that's more reliable if the code is buggy and sets
168 interrupt_input_blocked to a negative value. All uses changed.
169 * atimer.c (deliver_alarm_signal):
170 Remove. No need to deliver this to the parent; any thread can
171 handle this signal now. All uses replaced by underlying handler.
172 * atimer.c (turn_on_atimers):
173 * dispnew.c (handle_window_change_signal):
174 * emacs.c (handle_danger_signal):
175 * keyboard.c (kbd_buffer_get_event):
176 Don't reestablish signal handler; not needed with sigaction.
177 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
179 Rework to avoid unnecessary accesses to volatile variables.
180 (UNBLOCK_INPUT_TO): Now a function.
181 (totally_unblock_input, unblock_input): New decls.
182 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
183 (init_data): Remove. Necessary stuff now done in init_signal.
184 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
185 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
186 (fatal_error_code): Remove; no longer needed.
187 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
188 it doesn't always backtrace. All uses changed. No need to reset
189 signal to default, since sigaction and/or die does that for us now.
190 Use emacs_raise (FOO), not kill (getpid (), FOO).
191 (main): Check more-accurately whether we're dumping.
192 Move fatal-error setup to sysdep.c
193 * floatfns.c: Do not include "syssignal.h"; no longer needed.
194 * gtkutil.c (xg_get_file_name, xg_get_font):
195 Remove no-longer-needed signal-mask manipulation.
196 * keyboard.c, process.c (POLL_FOR_INPUT):
197 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
198 * keyboard.c (read_avail_input): Remove.
199 All uses replaced by gobble_input.
200 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
201 (kbd_buffer_store_event_hold, gobble_input):
202 (record_asynch_buffer_change) [USABLE_SIGIO]:
203 (store_user_signal_events):
204 No need to mess with signal mask.
205 (gobble_input): If blocking input and there are terminals, simply
206 set pending_signals to 1 and return. All hooks changed to not
207 worry about whether input is blocked.
208 (process_pending_signals): Clear pending_signals before processing
209 them, in case a signal comes in while we're processing.
210 By convention callers now test pending_signals before calling us.
211 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
212 New functions, to support changes to blockinput.h.
213 (handle_input_available_signal): Now extern.
214 (reinvoke_input_signal): Remove. All uses replaced by
216 (quit_count): Now volatile, since a signal handler uses it.
217 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg. All
218 callers changed. Block SIGINT only if not already blocked.
219 Clear sigmask reliably, even if Fsignal returns, which it can.
220 Omit unnecessary accesses to volatile var.
221 (quit_throw_to_read_char): No need to restore sigmask.
222 * keyboard.c (gobble_input, handle_user_signal):
223 * process.c (wait_reading_process_output):
224 Call signal-handling code rather than killing ourselves.
225 * lisp.h: Include <float.h>, for...
226 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
227 (pending_signals): Now volatile.
228 (syms_of_data): Now const if IEEE floating point.
229 (handle_input_available_signal) [USABLE_SIGIO]:
230 (terminate_due_to_signal, record_child_status_change): New decls.
231 * process.c (create_process): Avoid disaster if memory is exhausted
232 while we're processing a vfork, by tightening the critical section
234 (send_process_frame, process_sent_to, handle_pipe_signal)
235 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
237 (send_process): No need for setjmp/longjmp any more, since the
238 SIGPIPE stuff is now gone. Instead, report an error if errno
240 (record_child_status_change): Now extern. PID and W are now args.
241 Return void, not bool. All callers changed.
242 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
243 Remove. All uses removed. This bug should be fixed now in a
245 (wait_for_termination_1): Use waitpid rather than sigsuspend,
246 and record the child status change directly. This avoids the
247 need to futz with the signal mask.
248 (process_fatal_action): Move here from emacs.c.
249 (emacs_sigaction_flags): New function, containing
250 much of what used to be in emacs_sigaction_init.
251 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
252 caught by emacs, to make races less likely.
253 (deliver_process_signal): Rename from handle_on_main_thread.
255 (BACKTRACE_LIMIT_MAX): Now at top level.
256 (thread_backtrace_buffer, threadback_backtrace_pointers):
258 (deliver_thread_signal, deliver_fatal_thread_signal):
259 New functions, for more-accurate delivery of thread-specific signals.
260 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
261 (deliver_arith_signal): Handle in this thread, not
262 in the main thread, since it's triggered by this thread.
263 (maybe_fatal_sig): New function.
264 (init_signals): New arg DUMPING so that we can be more accurate
265 about whether we're dumping. Caller changed.
266 Treat thread-specific signals differently from process-general signals.
267 Block all signals while handling fatal error; that's safer.
268 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
270 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
271 Ignore SIGPIPE unless batch.
272 (emacs_backtrace): Output backtrace for the appropriate thread,
273 which is not necessarily the main thread.
274 * syssignal.h: Include <stdbool.h>.
275 (emacs_raise): New macro.
276 * xterm.c (x_connection_signal): Remove; no longer needed
277 now that we use sigaction.
278 (x_connection_closed): No need to mess with sigmask now.
279 (x_initialize): No need to reset SIGPIPE handler here, since
280 init_signals does this for us now.
282 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
284 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
285 background rect may be larger (Bug#12445).
287 2012-09-23 Chong Yidong <cyd@gnu.org>
289 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
291 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
293 * .gdbinit: Just stop at fatal_error_backtrace.
294 See Stefan Monnier's request in
295 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
296 Remove no-longer-used query of system type.
298 2012-09-22 Chong Yidong <cyd@gnu.org>
300 * search.c (Freplace_match): Doc fix (Bug#12325).

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

351 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
352 or that fprintf is async-signal-safe. POSIX doesn't require
355 2012-09-22 Chong Yidong <cyd@gnu.org>
357 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
360 2012-09-22 Kenichi Handa <handa@gnu.org>
362 * composite.c (composition_reseat_it): Handle the case that a
363 grapheme cluster is not covered by a single font (Bug#12352).
365 2012-09-21 Chong Yidong <cyd@gnu.org>
367 * image.c (define_image_type): Avoid adding duplicate types to
368 image_types (Bug#12463). Suggested by Jörg Walter.
370 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
372 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
373 (print_load_command_name): Add case LC_DATA_IN_CODE.
374 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.

381 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
383 * fileio.c (Ffile_selinux_context): Only call freecon when
384 lgetfilecon succeeded.
385 (Fset_file_selinux_context): Likewise. (Bug#12444)
387 2012-09-21 Eli Zaretskii <eliz@gnu.org>
389 * xdisp.c (try_window_reusing_current_matrix): Under bidi
390 reordering, locate the cursor by calling set_cursor_from_row; if
391 that fails, clear the desired glyph matrix before returning a
392 failure indication to the caller. Fixes leaving garbled display
393 when fast scrolling with a down-key. (Bug#12403)
394 (compute_stop_pos_backwards): Fix a typo that caused crashes while
395 scrolling through multibyte text.
397 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
399 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
400 calling mark_vectorlike since that's the one that marks the window.
401 (mark_discard_killed_buffers): Mark the final cdr.
402 * window.h (struct window): Move prev/next_buffers to the
404 * window.c (make_window): Initialize prev/next_buffers manually.

412 * w32inevt.c (w32_console_read_socket):
413 * w32term.c (w32_read_socket):
414 * xterm.c (XTread_socket):
415 Omit unused arg EXPECTED. All callers changed.
416 (store_user_signal_events): Return void, not int, since callers no
417 longer care about the return value. All uses changed.
419 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
421 * w32gui.h (XParseGeometry): Do not declare.
423 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
425 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
426 Ignore 'expected'. See Eli Zaretskii in

443 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
445 2012-09-17 Eli Zaretskii <eliz@gnu.org>
447 * search.c (scan_buffer): Use character positions in calls to
448 region_cache_forward and region_cache_backward, not byte
449 positions. (Bug#12196)
451 * w32term.c (w32_read_socket): Set pending_signals to 1, like
452 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
454 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
455 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
456 emacs_blocked_malloc, now deleted.
458 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
460 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
461 The workaround was for improving performance on Solaris 2.4, but
462 is getting in the way now. Emacs will still work if someone is
463 still running Solaris 2.4 in a museum somewhere; Sun dropped
464 support for Solaris 2.4 in 2003.
465 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
466 * process.c (create_process) [HAVE_WORKING_VFORK]:
467 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
468 since Emacs no longer uses vfork on that platform.
470 2012-09-17 Glenn Morris <rgm@gnu.org>
472 * emacs.c: Use COPYRIGHT.
474 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
476 Remove configure's --without-sync-input option (Bug#12450).
477 When auditing signal-handling in preparation for cleaning it up,
478 I found that SYNC_INPUT has race conditions and would be a real
479 pain to fix. Since it's an undocumented and deprecated
480 configure-time option, now seems like a good time to remove it.
481 Also see <http://bugs.gnu.org/11080#16>.
482 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
483 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
484 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
486 (check_depth) [XMALLOC_OVERRUN_CHECK]:
487 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
488 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
489 (dont_register_blocks, bytes_used_when_reconsidered)
490 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
491 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
492 [!SYSTEM_MALLOC && !SYNC_INPUT]:
493 Remove. All uses removed.
494 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
495 implementation, one that depends on whether the new macro
496 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
498 * atimer.c (run_timers, handle_alarm_signal):
499 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
500 (handle_async_input, process_pending_signals)
501 (handle_input_available_signal, init_keyboard):
502 * nsterm.m (ns_read_socket):
503 * process.c (wait_reading_process_output):
504 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
505 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
507 * xterm.c (XTread_socket):
509 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
510 * eval.c (handling_signal): Remove. All uses removed.
511 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
512 All uses replaced with the SYNC_INPUT version.
513 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
515 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
518 * font.c (Ffont_shape_gstring): Remove unused local.
520 2012-09-16 Glenn Morris <rgm@gnu.org>
522 * Makefile.in (clean): No longer run nextstep's clean.
524 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
526 (ns-app): Move here from ns.mk, and simplify.
527 (clean): Simplify nextstep entry.
528 * ns.mk: Remove file.
530 2012-09-17 Kenichi Handa <handa@gnu.org>
532 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
533 not covert the last few charactes.
535 2012-09-16 Kenichi Handa <handa@gnu.org>
537 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
538 here, but just check the validity of glyphs in the glyph-string.
540 2012-09-16 Martin Rudalics <rudalics@gmx.at>
542 * window.c (Fwindow_parameter, Fset_window_parameter): Accept
543 any window as argument (Bug#12452).
545 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
547 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
548 to ns_term_init to avoid memory leak.
550 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
551 explicit retain/release.
552 (ns_term_init): Only allow one display. Initialize outerpool and
555 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
557 Port _setjmp fix to POSIXish hosts as well as Microsoft.
558 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
559 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
560 the Microsoft problem in a different way, by altering ../nt/config.nt.
562 2012-09-15 Eli Zaretskii <eliz@gnu.org>
577 * w16select.c: Remove inclusion of setjmp.h, as it is now included
578 by lisp.h. This completes removal of setjmp.h inclusion
579 erroneously announced in the previous commit. (Bug#12446)
581 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
584 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
585 not defined as a macro. The latter happens on MS-Windows.
588 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
590 Port better to POSIX hosts lacking _setjmp (Bug#12446).
591 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
592 Some instances of '#include <setjmp.h>' removed, if the
593 only reason for the instance was because "lisp.h" was included.
594 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
595 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
596 and _longjmp with the new symbols. Emacs already uses _setjmp if
597 available, so this change affects only POSIXish hosts that have
598 sigsetjmp but not _setjmp, such as some versions of Solaris and
599 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
600 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
601 (png_load_body) [HAVE_PNG]:
602 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
603 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
604 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
605 since PNG requires jmp_buf. This is the only exception to the
606 general rule that we now use sys_setjmp and sys_longjmp.
607 This exception is OK since this code does not change the signal
608 mask or longjmp out of a signal handler.
610 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
612 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
613 Include "syssignal.h", for 'main_thread'.
615 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
617 Avoid out-of-range marker position (Bug#12426).
618 * insdel.c (replace_range, replace_range_2): Adjust
619 markers before overlays, as suggested by comments.
620 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
621 Remove redundant check before calling offset_intervals.
623 2012-09-14 Martin Rudalics <rudalics@gmx.at>
625 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
626 current buffer (Bug#12387).
628 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
630 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
632 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
634 Use a more backwards-compatible timer format (Bug#12430).
635 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
636 vector element, not from the 4th, since PSECS is now at the end.
637 (Fcurrent_idle_time): Doc fix.
639 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
641 Function to mark objects and remove killed buffers at once.
642 * alloc.c (discard_killed_buffers): Rename to ...
643 (mark_discard_killed buffers) ... new name. Add marking
644 of remaining objects. Fix comment. Adjust users.
645 (mark_object): Do not touch frame buffer lists here.
646 * frame.c (delete_frame): Reset frame buffer lists here.
648 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
650 Better workaround for GNOME bug when --enable-gcc-warnings.
651 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
652 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
653 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
655 Simplify SIGIO usage (Bug#12408).
656 The code that dealt with SIGIO was crufty and confusing, e.g., it
657 played tricks like "#undef SIGIO" but these tricks were not used
658 consistently. Simplify mostly by not #undeffing standard symbols,
659 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
660 or not as we please) rather than "defined SIGIO" (standard symbol
661 that we probably shouldn't #undef).
662 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
663 Modules that need it can include it.
664 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
665 * dispextern.h (ignore_sigio): New decl.
666 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
667 unconditionally, since it's now a no-op if !USABLE_SIGIO.
668 * emacs.c (shut_down_emacs):
669 * keyboard.c (kbd_buffer_store_event_hold):
670 Use ignore_sigio rather than invoking 'signal' directly.
671 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
673 (FIONREAD, SIGIO): Do not #undef.
674 (tty_read_avail_input): Use #error rather than a syntax error.
675 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
676 for I_PIPE, used by SETUP_SLAVE_PTY.
677 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
678 * sysdep.c (croak): Remove; no longer needed. This bit of
679 temporary code, with Fred N. Fish's comment that it's temporary,
680 has been in Emacs since at least 1992!
681 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
682 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
683 * syssignal.h (croak): Remove decl.
684 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
685 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
686 now that we're termios-only.
687 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
688 * term.c (dissociate_if_controlling_tty): Use #error rather than
691 Work around GCC and GNOME bugs when --enable-gcc-warnings.
692 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
693 to work around GNOME bug 683906.
694 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
695 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
696 This works around GCC bug 54561.
698 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
700 More fixes for 'volatile' and setjmp/longjmp.
701 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
702 * image.c (struct png_load_context) [HAVE_PNG]: New type.
703 (png_load_body) [HAVE_PNG]:
704 (jpeg_load_body) [HAVE_JPEG]:
705 New function, with most of the old parent function's body.
706 (png_load) [HAVE_PNG]:
707 (jpeg_load) [HAVE_JPEG]:
708 Invoke the new function, to avoid longjmp munging our locals.
709 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
710 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
711 longjmp is passed 2, as the C standard doesn't guarantee this.
712 Instead, store the failure code into mgr->failure_code.
714 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
716 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
717 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
718 (syms_of_keyboard): Remove support for unread-command-char.
720 2012-09-12 Eli Zaretskii <eliz@gnu.org>
722 * w32proc.c (sys_kill): If PID is our process ID and the signal is
723 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
724 violation. (Bug#12426)
726 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
728 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
730 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
732 * eval.c: Add `inhibit-debugger'.
733 (Qinhibit_debugger): New symbol.
734 (call_debugger): Bind it instead of Qdebug_on_error.
735 (maybe_call_debugger): Test Vinhibit_debugger.
736 (syms_of_eval): Define inhibit-debugger.
737 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
738 (syms_of_xdisp): Remove inhibit-debug-on-message.
740 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
742 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
743 If a nonvolatile local variable is written before a _longjmp to
744 the frame containing the variable, and is read after the _longjmp,
745 the value read is indeterminate. Some local variables of type
746 'struct handler' and 'struct catchtag' are used in this way, so
747 mark each of their slots as volatile if the slot can be set before
748 _longjmp and read afterwards.
749 * lisp.h (struct handler): var and chosen_clause are now volatile.
750 (struct catchtag): val, next, and pdlcount are now volatile.
752 * bidi.c (bidi_push_it, bidi_pop_it):
753 * fns.c (copy_hash_table):
754 * image.c (define_image_type):
755 * keyboard.c (kbd_buffer_store_event_hold):
756 * process.c (Fprocess_send_eof):
757 * xfaces.c (x_create_gc) [HAVE_NS]:
758 * xgselect.c (xg_select):
759 Prefer assignment to memcpy when either will do.
761 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
762 Use pointer-to-a-pointer to simplify and avoid a NILP check each
763 time an item is removed. No need to mark this function 'inline';
764 the compiler knows better than we do.
766 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
768 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
769 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
770 to change_frame_size (Bug#12388).
771 (windowDidResize:): Pass YES to updateFrameSize.
773 * nsterm.h: Add delay parameter to updateFrameSize.
775 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
777 Discard killed buffers from deleted window and frame objects.
778 This reduces an amount of references to killed buffers and
779 helps GC to reclaim them faster.
780 * alloc.c (discard_killed_buffers): New function.
781 (mark_object): Use it for deleted windows and frames.
782 (mark_object): If symbol's value is set up for a killed buffer
783 or deleted frame, restore it's global binding.
784 * data.c (swap_in_global_binding): Add GC notice.
785 (swap_in_symval_forwarding): Use convenient set_blv_where.
786 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
787 * window.h: ... to here.
789 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
791 Convenient macro to check whether the buffer is live.
792 * buffer.h (BUFFER_LIVE_P): New macro.
793 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
794 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
796 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
798 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
799 composition cases (Bug#12364).
801 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
802 overhang of succeeding glyphs overlapping box cursor.
804 * w32term.c (x_draw_glyph_string): Likewise.
806 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
808 Simplify, document, and port floating-point (Bug#12381).
809 The porting part of this patch fixes bugs on non-IEEE platforms
810 with frexp, ldexp, logb.
811 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
813 * floatfns.c: Simplify discussion of functions that Emacs doesn't
814 support, by removing commented-out code and briefly listing the
815 C89 functions excluded. The commented-out stuff was confusing
816 maintenance, e.g., we thought we needed cbrt but it was commented out.
817 (logb): Remove decl; no longer needed.
818 (isfinite): New macro, if not already supplied.
819 (isnan): Don't replace any existing macro.
820 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
821 are present on all C89 platforms.
822 (Ffrexp): Do not special-case zero, as frexp does the right thing
824 (Flogb): Do not use logb, as it doesn't have the desired meaning
825 on hosts that use non-base-2 floating point. Instead, stick with
826 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
827 frexp, to avoid getting an unspecified result.
829 * xdisp.c (Qinhibit_debug_on_message): Now static.
831 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
833 * nsterm.m (ns_update_begin): Set clip path to whole view by using
834 NSBezierPath (Bug#12131).
836 2012-09-10 Chong Yidong <cyd@gnu.org>
838 * fns.c (Fdelq, Fdelete): Doc fix.
840 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
842 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
843 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
845 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
847 * lisp.h (make_lisp_ptr): New macro to replace XSET.
848 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
851 2012-09-09 Eli Zaretskii <eliz@gnu.org>
853 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
854 left fringe if the window has a left margin. This avoids leaving
855 traces of the cursor because its leftmost pixel is not drawn over.
857 * dispnew.c (update_window_line): When the left margin area of a
858 screen line is updated, set the redraw_fringe_bitmaps_p flag of
859 that screen line. (Bug#12277)
861 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
863 Assume C89 or later for math functions (Bug#12381).
864 This simplifies the code, and makes it a bit smaller and faster,
865 and (most important) makes it easier to clean up signal handling
866 since we can stop worring about floating-point exceptions in
867 library code. That was a problem before C89, but the problem
868 went away many years ago on all practical Emacs targets.
869 * data.c, image.c, lread.c, print.c:
870 Don't include <math.h>; no longer needed.
871 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
872 might be autoconfigured, as that never happens.
874 * doprnt.c (DBL_MAX_10_EXP):
876 Remove. C89 or later always defines these.
877 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
878 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
879 (arith_error, domain_error, domain_error2):
880 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
881 no longer needed -- we simply return what C returns. All uses removed.
882 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
884 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
885 Remove. All uses expanded, as these macros are no longer used
886 more than once and are now more trouble than they're worth.
887 (Ftan): Use tan, not sin / cos.
888 (Flogb): Assume C89 frexp.
889 (fmod_float): Assume C89 fmod.
890 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
891 (init_floatfns): Remove. All uses removed.
893 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
895 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
896 compositeToPoint for OSX < 10.6 (Bug#12390).
898 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
900 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
901 This produces more-accurate results.
903 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
905 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
908 2012-09-08 Chong Yidong <cyd@gnu.org>
910 * syntax.c (Fstring_to_syntax): Doc fix.
912 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
914 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
915 in the internal border.
916 (x_set_window_size): Remove static variables and their usage.
917 (ns_redraw_scroll_bars): Fix NSTRACE arg.
918 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
919 fringe/internal border adjustment (Bug#11052).
920 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
921 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
922 (ns_fix_rect_ibw): Remove.
923 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
924 (ns_dumpglyphs_box_or_relief): Ditto.
925 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
927 (ns_dumpglyphs_image): Ditto.
928 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
930 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
931 their usage. Add fringe_extended_p and its use as in other terms.
932 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
933 scroll bar was removed.
934 (updateFrameSize): New function.
935 (windowDidResize): Move code to updateFrameSize and call it.
937 * nsterm.h (EmacsView): Add updateFrameSize.
939 2012-09-07 Chong Yidong <cyd@gnu.org>
941 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
943 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
945 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
947 More signal-handler cleanup (Bug#12327).
948 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
949 Problem introduced when merging patches. Noted by Eli Zaretskii in
950 <http://bugs.gnu.org/12327#67>.
951 * floatfns.c: Comment fix.
952 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
953 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
954 and anyway the declaration is harmless even if SIGDANGER is not defined.
955 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
956 defined BROKEN_FIONREAD). systty.h formerly did this, but other
957 source files not surprisingly expected syssignal.h to define, or
958 not define, SIGIO, and it's cleaner to do it that way, for consistency.
959 Include <sys/ioctl.h>, for FIONREAD.
960 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
961 This eliminates a problem whereby other files mysteriously had
962 to include "syssignal.h" before including "systty.h" if they
963 wanted to use "#ifdef SIGIO".
965 2012-09-07 Eli Zaretskii <eliz@gnu.org>
967 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
969 * w32.c (sigemptyset): Empty the set.
970 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
972 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
974 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
976 * alloc.c (mark_buffer): Revert unsafe marking optimization.
977 (mark_object): Likewise for frame objects.
979 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
981 * syssignal.h (handle_on_main_thread): Always declare,
982 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
983 This ports to platforms without HAVE_PTHREAD.
985 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
987 Signal-handler cleanup (Bug#12327).
988 Emacs's signal handlers were written in the old 4.2BSD style with
989 sigblock and sigmask and so forth, and this led to some
990 inefficiencies and confusion. Rewrite these to use
991 pthread_sigmask etc. without copying signal sets around. Also,
992 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
993 'signal', and instead use functions that do not attempt to take
994 over the system name space. This patch causes Emacs's text
995 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
996 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
997 Do not include <signal.h> or "syssignal.h", as these
998 modules do not use signals.
999 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
1000 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
1001 Do not include <signal.h>, as "syssignal.h" does that for us now.
1002 * atimer.c (sigmask_atimers): New function.
1003 (block_atimers, unblock_atimers): New functions,
1004 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
1006 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
1007 no longer needed here.
1008 * emacs.c (main): Inspect existing signal handler with sigaction,
1009 so that there's no need to block and unblock SIGHUP.
1010 * sysdep.c (struct save_signal): New member 'action', replacing
1011 old member 'handler'.
1012 (save_signal_handlers, restore_signal_handlers):
1013 Use sigaction instead of 'signal' to save and restore.
1014 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
1015 New function. All users of 'signal' modified to use set_sighandler
1016 if they're writeonly, and to use sys_signal if they're read+write.
1017 (emacs_sigaction_init, forwarded_signal): New functions.
1018 (sys_signal): Remove. All uses replaced by calls to sigaction
1019 and emacs_sigaction_init, or by direct calls to 'signal'.
1020 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
1021 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
1022 all uses replaced by pthread_sigmask etc. calls.
1023 * syssignal.h: Include <signal.h>.
1024 (emacs_sigaction_init, forwarded_signal): New decls.
1025 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
1026 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
1027 (sigmask, sys_sigmask): Remove; no longer needed.
1028 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
1029 (sigblock, sigunblock, sigfree):
1030 (sigsetmask) [!defined sigsetmask]:
1031 Remove. All uses replaced by pthread_sigmask.
1032 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
1033 no longer need to be replaced, and its typical old uses
1034 are now done via emacs_sigaction_init and sigaction.
1035 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
1036 (sys_sigdel): Remove; unused.
1037 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
1039 2012-09-06 Eli Zaretskii <eliz@gnu.org>
1041 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
1042 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
1044 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1046 Explicitly mark buffer_defaults and buffer_local_symbols.
1047 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
1048 mark_local_symbols here.
1049 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
1050 since special buffers aren't marked here any more.
1051 (allocate_buffer): Chain new buffer with all_buffers here...
1052 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
1054 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
1055 (syms_of_buffer): Remove staticpro of the above.
1056 (init_buffer_once): Set names for buffer_defaults and
1057 buffer_local_symbols.
1059 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1061 Use bool for booleans in font-related modules.
1062 * font.c (font_intern_prop, font_style_to_value)
1063 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
1064 (generate_otf_features, font_check_otf_features, font_check_otf)
1065 (font_match_p, font_list_entities, font_at):
1066 * fontset.c (fontset_id_valid_p, reorder_font_vector
1067 (fontset_find_font, Fset_fontset_font)
1068 (face_suitable_for_char_p) [0]:
1069 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
1070 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
1071 (m17n_flt_initialized, ftfont_shape_by_flt):
1072 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
1073 * nsfont.m (nsfont_draw):
1074 * w32font.c (w32font_draw):
1075 * w32term.c (x_draw_glyphless_glyph_string_foreground):
1076 Use bool for booleans.
1077 * font.h: Adjust to above API changes.
1078 (struct font, struct font_driver, struct font_driver_list):
1079 Use bool for booleans.
1080 (struct font): Remove useless member encoding_type.
1082 * fontset.c, xftfont.c: Omit unnecessary static decls.
1084 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1086 * alloc.c (mark_object): Revert window marking code
1087 since it's unsafe for the Fset_window_configuration.
1089 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1091 Fix race conditions with signal handlers and errno (Bug#12327).
1092 Be more systematic about preserving errno whenever a signal
1093 handler returns, even if it's not in the main thread. Do this by
1094 renaming signal handlers to distinguish between signal delivery
1095 and signal handling. All uses changed.
1096 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
1097 * data.c (deliver_arith_signal): Rename from arith_error.
1098 * dispnew.c (deliver_window_change_signal): Rename from
1099 window_change_signal.
1100 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
1101 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
1102 * keyboard.c (deliver_input_available_signal): Rename from
1103 input_available_signal.
1104 (deliver_user_signal): Rename from handle_user_signal.
1105 (deliver_interrupt_signal): Rename from interrupt_signal.
1106 * process.c (deliver_pipe_signal): Rename from send_process_trap.
1107 (deliver_child_signal): Rename from sigchld_handler.
1108 * atimer.c (handle_alarm_signal):
1109 * data.c (handle_arith_signal):
1110 * dispnew.c (handle_window_change_signal):
1111 * emacs.c (handle_fatal_signal, handle_danger_signal):
1112 * keyboard.c (handle_input_available_signal):
1113 * keyboard.c (handle_user_signal, handle_interrupt_signal):
1114 * process.c (handle_pipe_signal, handle_child_signal):
1115 New functions, with the actual signal-handling code taken from the
1116 original respective signal handlers, sans the sporadic attempts to
1117 preserve errno, since that's now done by handle_on_main_thread.
1118 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
1119 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
1120 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1122 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1123 Move initialization of main_thread to sysdep.c's init_signals.
1124 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
1125 our usage, and simplifies the mainline code.
1126 (record_child_status_change): New static function, as a helper
1127 for handle_child_signal, and with most of the old child handler's
1129 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
1130 (handle_child_signal): Use the above.
1131 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1132 Moved here from emacs.c.
1133 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
1134 code moved here from emacs.c's main function.
1135 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
1136 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
1137 lets callers save and restore errno properly.
1139 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1141 Remove redundant or unused things here and there.
1142 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
1143 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
1144 * editfns.c (Fcompare_buffer_substrings): Likewise.
1145 * frame.h (struct terminal, struct font_driver_list):
1146 Remove redundant declarations.
1147 * window.h (Qleft, Qright): Likewise.
1149 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1151 Do not mark objects from deleted buffers, windows and frames.
1152 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
1153 (mark_object): Likewise for windows and frames.
1155 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1157 * alloc.c (valid_lisp_object_p): Treat killed buffers,
1158 buffer_defaults and buffer_local_symbols as valid objects.
1159 Return special value to denote them.
1161 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1163 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
1164 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
1165 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
1166 (file_name_absolute_p, Fsubstitute_in_file_name):
1167 (check_executable, check_writable, Ffile_accessible_directory_p)
1168 (Fset_file_selinux_context, Fdefault_file_modes)
1169 (Finsert_file_contents, choose_write_coding_system)
1170 (Fwrite_region, build_annotations, a_write, e_write)
1172 * filelock.c (boot_time_initialized, get_boot_time)
1173 (get_boot_time_1, lock_file_1, within_one_second):
1174 * floatfns.c (in_float):
1175 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
1176 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
1177 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
1178 * lisp.h (struct Lisp_Hash_Table.cmpfn):
1179 * window.c (compare_window_configurations):
1180 Use bool for booleans.
1181 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
1182 (Fdefault_file_modes): Now mode_t, not int, for modes.
1183 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
1184 (internal_delete_file): Now returns void, not a (boolean) int,
1185 since nobody was looking at the return value.
1186 * lisp.h, window.h: Adjust to above API changes.
1188 * xdisp.c (set_message): Simplify and reindent last change.
1190 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
1192 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
1194 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
1196 * eval.c (call_debugger): Make the function non-static so that we
1197 can call it from set_message.
1199 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
1200 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
1202 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1204 Give more-useful info on a fatal error (Bug#12328).
1205 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
1206 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
1207 of doing the work ourselves.
1208 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
1209 do most of the work.
1210 (fatal_error_backtrace): New function, taken from the guts
1211 of the old fatal_error_signal, but with a new option to output
1213 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
1214 info about the signal than just its number.
1215 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
1216 * sysdep.c: Include <execinfo.h>
1217 (emacs_backtrace): New function, taken partly from the previous
1218 code of the 'die' function.
1219 (emacs_abort): Call fatal_error_backtrace rather than abort.
1221 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
1223 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
1224 eager (load-time) macro-expansion.
1225 * lisp.mk (lisp): Add macroexp.
1227 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1229 Simplify redefinition of 'abort' (Bug#12316).
1230 Do not try to redefine the 'abort' function. Instead, redo
1231 the code so that it calls 'emacs_abort' rather than 'abort'.
1232 This removes the need for the NO_ABORT configure-time macro
1233 and makes it easier to change the abort code to do a backtrace.
1234 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
1235 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
1236 Remove; sysdep.c's emacs_abort now takes its place.
1237 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
1238 'abort' changed to use 'emacs_abort'.
1239 * msdos.c (dos_abort) [defined abort]: Remove; not used.
1240 (abort) [!defined abort]: Rename to ...
1241 (emacs_abort): ... new name.
1242 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
1243 the place of the old 'abort' in emacs.c.
1244 * w32.c, w32fns.c (abort): Do not #undef.
1245 * w32.c (emacs_abort): Rename from w32_abort.
1247 2012-09-04 Eli Zaretskii <eliz@gnu.org>
1249 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
1250 offsets[j].dv, since the y axis of the screen coordinates points
1251 down, while the y axis of the font definition coordinates points
1252 up. This fixes display of Arabic diacritics such as KASRA and
1253 KASRATAN. (Bug#11860)
1255 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1257 Be more systematic about _setjmp vs setjmp.
1258 * alloc.c (test_setjmp, mark_stack):
1259 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
1260 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
1261 (png_load, my_error_exit, jpeg_load):
1262 * process.c (send_process_trap, send_process):
1263 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
1264 The underscored versions are up to 30x faster on some hosts.
1265 Formerly, the code used setjmp+longjmp sometimes and
1266 _setjmp+_longjmp at other times, with no particular reason to
1267 prefer setjmp+longjmp.
1269 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
1271 Fix minor problem found by static checking.
1272 * buffer.c (Fdelete_all_overlays): Return nil.
1274 2012-09-03 Martin Rudalics <rudalics@gmx.at>
1276 * buffer.c (Fdelete_all_overlays): New function.
1278 2012-09-03 Chong Yidong <cyd@gnu.org>
1280 * gtkutil.c: Add extern decl for Qxft.
1282 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
1284 * emacs.c, eval.c: Use bool for boolean.
1285 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
1286 (malloc_using_checking) [DOUG_LEA_MALLOC]:
1287 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
1288 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
1289 (main, decode_env_path, Fdaemon_initialized):
1290 * eval.c (call_debugger, Finteractive_p, interactive_p):
1291 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
1292 (maybe_call_debugger, Fbacktrace):
1293 * process.c (read_process_output, exec_sentinel):
1294 Use bool for booleans.
1295 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
1296 All callers changed.
1297 * eval.c (interactive_p): Omit always-true boolean argument
1298 EXCLUDE_SUBRS_P. All callers changed.
1299 * dispextern.h, lisp.h: Reflect above API changes.
1300 * firstfile.c (dummy): Use the address of 'main', whose signature
1301 won't change, instead of the address of 'initialize', whose
1302 signature just changed from int to bool.
1303 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
1304 * msdos.c (fatal_error_in_progress): ... from here.
1305 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
1307 (redisplay_internal, unwind_redisplay): Simply clear
1308 REDISPLAYING_P when unwinding, instead of saving its previous,
1309 always-false value and then restoring it.
1311 Clean up some extern decls.
1312 Mostly, this hoists extern decls out of .c files and into .h files.
1313 That way, we're more likely to catch errors if the interfaces change.
1314 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
1315 declare xg_mark_data.
1316 * dispextern.h (x_frame_parm_handlers):
1318 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
1319 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
1320 (Qultra_bold, Qoblique, Qitalic):
1321 Move extern decl here from .c file.
1322 * alloc.c (xg_mark_data) [USE_GTK]:
1324 * eval.c (Qlexical_binding):
1325 * fns.c (time) [!HAVE_UNISTD_H]:
1326 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
1327 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
1328 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
1329 * lread.c (Qinternal_interpreter_environment):
1330 * minibuf.c (Qbuffer):
1331 * process.c (QCfamily, QCfilter):
1332 * widget.c (free_frame_faces):
1333 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
1334 * xfont.c (x_clear_errors):
1335 * xterm.c (x_frame_parm_handlers):
1336 Remove now-redundant extern decls.
1337 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
1338 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
1340 * xfaces.c: Remove unnecessary static decls.
1341 * xterm.c (updating_frame): Remove decl of nonexistent object.
1343 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
1344 when building globals.h, as the objects that are not built on
1345 this host are not needed to compile C files on this host.
1347 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>

1401 offset adjustment values separately for each cluster. (Bug#11860)
1403 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1404 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1405 about implicit conversions from integer to pointer.

1463 window system declarations.
1465 * frame.h: Move common functions here: set_frame_menubar,
1466 x_set_window_size, x_sync, x_get_focus_frame,
1467 x_set_mouse_position, x_set_mouse_pixel_position,
1468 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

1525 for GCC 4.7.1 x86-64.
1527 2012-08-30 Glenn Morris <rgm@gnu.org>
1529 * lread.c (init_lread): For out-of-tree builds, only add the
1530 source directory's site-lisp dir to the load-path if it exists,
1531 consistent with in-tree builds. (Bug#12302)
1533 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

1763 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
1764 are all boolean, so make them single-bit bitfields.
1766 * lisp.h (ASET): Remove attempt to detect side effects.
1767 It was meant to be temporary and it often doesn't work,
1768 because when IDX has side effects the behavior of IDX==IDX
1769 is undefined. See Stefan Monnier in
1770 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
1772 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

1775 (FUNCTIONP): Use it.
1776 * eval.c (Ffunctionp): Use it.
1778 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1780 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
1781 as that's faster and simpler than static storage. Don't bother
1782 with the g_main_context_query overhead if g_main_context_pending
1783 says no events are pending.
1784 (gfds, gfds_size): Remove these static vars.
1785 (xgselect_initialize): Remove; no longer needed.
1786 All uses and decls removed.

1800 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
1802 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1804 On assertion failure, print backtrace if available.
1805 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1806 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1807 * Makefile.in (LIB_EXECINFO): New macro.
1810 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1811 * bytecode.c (exec_byte_code):
1812 * callint.c (check_mark, Fcall_interactively):
1813 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1814 (getenv_internal, sync_process_alive, call_process_exited):
1815 * lisp.h (USE_SAFE_ALLOCA):
1816 Use bool for booleans, instead of int.
1817 * lisp.h, process.h: Adjust prototypes to match above changes.
1818 * callint.c (Fcall_interactively): Don't assume the mark's
1819 offset fits in 'int'.
1821 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1823 * buffer.c, buffer.h: Use bool for boolean.
1824 * buffer.c (reset_buffer_local_variables)
1825 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1826 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
1827 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
1828 (overlay_touches_p, overlay_strings, Foverlay_put)
1829 (report_overlay_modification, call_overlay_mod_hooks):
1830 (mmap_enlarge, mmap_set_vars):
1831 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1832 Use bool for booleans, instead of int.
1833 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1834 since the 1-or-0 return value is always ignored anyway.
1835 (mmap_initialized_p):
1836 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1837 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1839 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1841 * bidi.c: Use bool for boolean.
1842 This is a bit more readable, and makes the text segment of bidi.o
1843 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1844 Presumably it's faster too.
1845 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1847 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1848 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1849 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1850 (bidi_explicit_dir_char, bidi_level_of_next_char)
1851 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1852 Use bool for booleans, instead of int.
1853 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1854 (bidi_unshelve_cache): Adjust decls to match code.
1856 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1858 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1861 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1863 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1864 * atimer.h: Include <stdbool.h>.
1866 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1868 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1869 compile time tests instead of run time tests on systems that do
1871 (FRAME_MAC_P): Remove leftover from deleted code.
1872 * frame.c (syms_of_frame): Remove leftover from deleted code.
1874 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>

1878 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1880 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1881 Otherwise, the compiler complains about (A?B:C) where B is void
1882 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1883 (fontset_add): Return void, for FONTSET_ADD.
1885 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1887 * alloc.c: Use bool for booleans.
1888 (gc_in_progress, abort_on_gc)
1889 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1890 (dont_register_blocks) [GC_MALLOC_CHECK]:
1891 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1892 (check_string_bytes, make_specified_string, memory_full)
1893 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1894 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1895 (mark_stack, valid_pointer_p, make_pure_string)
1896 (Fgarbage_collect, survives_gc_p, gc_sweep):
1897 Use bool for booleans, instead of int.
1898 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1899 Remove unused local.
1900 * alloc.c (PURE_POINTER_P):
1901 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1902 * editfns.c (Fformat):
1903 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1905 * fns.c (sweep_weak_table):
1906 * lisp.h (suppress_checking, push_message, survives_gc_p)
1907 (make_pure_string, gc_in_progress, abort_on_gc):
1908 * lread.c (readchar, read1):
1909 * print.c (Fprin1_to_string):
1910 * xdisp.c (push_message):
1911 Use bool for booleans affected directly or indirectly by
1914 Make recently-introduced setters macros.
1915 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1916 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1917 (set_fontset_default, set_fontset_fallback): Rename from their
1918 upper-case counterparts, and make them functions rather than macros.
1919 This is more consistent with the other recently-introduced setters.
1920 These don't need to be inline, since they're local.
1922 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1924 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1925 the loop (Bug#12247).
1927 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1929 * lisp.h (vcopy): Use memcpy rather than our own loop.
1930 This fixes a performance regression introduced by the recent
1931 addition of vcopy. This means 'vcopy' will need to be modified
1932 for a copying collector, but that's OK. Also, tighten the
1933 checking in the assertion.
1935 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1937 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1938 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1939 non-base glyph for the width of the base character, according to
1940 what x_draw_composite_glyph_string_foreground expects.
1941 Generate WADJUST value according to composition_gstring_width's
1942 expectations, to produce correct width of the composed character.
1943 Reverse the sign of the DU offset produced by ScriptPlace.
1945 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1947 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1949 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1951 Avoid direct writes to contents member of struct Lisp_Vector.
1952 * lisp.h (vcopy): New function to copy data into vector.
1953 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
1954 * fns.c (Ffillarray): Use ASET.
1955 * keyboard.c (timer_check_2): Use AREF and ASET.
1956 (append_tool_bar_item, Frecent_keys): Use vcopy.
1957 * lread.c (read_vector): Use ASET.
1958 * msdos.c (Frecent_doskeys): Use vcopy.
1959 * xface.c (Finternal_copy_lisp_face): Use vcopy.

1966 the position of its buffer's point.
1967 (Fset_window_point): For the selected window always go in its
1968 buffer to the specified position.
1970 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1972 Setter macros for fontsets.
1973 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1974 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1975 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1978 2012-08-20 Glenn Morris <rgm@gnu.org>
1980 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1981 Don't assume that `ln -f' works.
1983 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1985 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1986 and later about non-assignments with no effect. See discussion at
1987 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1990 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1992 Inline setter functions for Lisp_Objects slots of struct specbinding.
1993 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
1996 2012-08-20 Martin Rudalics <rudalics@gmx.at>
1998 * window.c (select_window): Always make selected window's buffer
2001 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2003 Use AREF and ASET for docstrings of category tables.
2004 * category.h (CATEGORY_DOCSTRING): Use AREF.
2005 (SET_CATEGORY_DOCSTRING): Use ASET.
2006 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
2008 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2010 Inline setter functions for hash table members.
2011 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
2012 (set_hash_hash, set_hash_index): Rename with _slot suffix.
2013 (set_hash_key_and_value, set_hash_index, set_hash_next)
2014 (set_hash_hash): New functions.
2015 * charset.c, fns.c: Adjust users.
2017 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2019 Inline getter and setter functions for per-buffer values.
2020 * buffer.h (per_buffer_default, set_per_buffer_default)
2021 (per_buffer_value, set_per_buffer_value): New functions.

2023 * buffer.c, data.c: Adjust users.
2025 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
2027 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
2029 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
2031 Rely on <config.h> + <unistd.h> to declare 'environ',
2032 as gnulib does this if the system doesn't.
2033 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
2034 Remove declaration. MS-Windows declares it on stdlib.h which is
2035 included by conf_post.h.
2036 * emacs.c (environ) [DOUG_LEA_MALLOC]:
2037 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
2038 * vm-limit.c: Include <unistd.h>, for 'environ'.
2040 * unexaix.c, unexcoff.c: Include "mem-limits.h".
2041 (start_of_data): Remove decl; mem-limits.h provides it.
2043 * xdisp.c (handle_invisible_prop): Make it a bit faster
2044 and avoid a gcc -Wmaybe-uninitialized diagnostic.
2046 2012-08-19 Chong Yidong <cyd@gnu.org>
2048 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string

2057 (Fkill_local_variable): Likewise.
2059 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
2061 * nsfont.m (ns_ascii_average_width): Ensure the string
2062 ascii_printable is initialized with a null-terminated character
2063 array. Otherwise, it can contain undesired extra characters.

2068 * chartab.c, lisp.h (char_table_set, char_table_set_range):
2069 Return void, not Lisp_Object. Otherwise, the compiler
2070 complains about (A?B:C) where B is void and C is Lisp_Object
2071 when compiling CHAR_TABLE_SET, due to the recent change to
2072 the API of sub_char_table_set_contents.
2074 2012-08-18 Chong Yidong <cyd@gnu.org>
2076 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
2077 for the string case (Bug#3874).

2905 * w32.c (init_environment): Change the default values of many
2906 environment variables in dflt_envvars[] to NULL, to avoid pushing
2907 them into environment when they were not already defined.
2908 Remove the code that deletes site-lisp subdirectories from the default
2909 value of EMACSLOADPATH, as it is no longer needed.
2910 (check_windows_init_file): Now external, not static.
2911 Use Vload_path as is, without adding anything, as this function is now
2912 called when Vload_path is already set up.
2914 * w32.h (check_windows_init_file): Add prototype.
2916 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

2959 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
2960 Remove unnecessary pointer casts.
2961 * alloc.c (record_xmalloc): New function.
2962 * lisp.h (record_xmalloc): New decl.
2963 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
2964 more like a function. This is because the pointer cast is not
2965 needed. All uses changed.
2966 * print.c (print_string, print_error_message): Avoid length recalc.
2968 Improve fix for macroexp crash with debugging (Bug#12118).
2969 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
2970 ARRAY_MARK_FLAG when checking subscripts, because ASET is
2971 not supposed to be invoked from the garbage collector.

2973 (gc_aset): New function, which is like ASET but can be
2974 used in the garbage collector.

3003 with addition of handling of symlinks and support for 'lstat'.
3004 If possible, get file's attributes and security information by
3005 handle, not by name. Produce S_IFLNK bit for symlinks, when
3006 called from 'lstat'.
3007 (stat, lstat): New functions, call 'stat_worker'.
3008 (symlink, readlink, careadlinkat): Rewritten to create and resolve
3009 symlinks when the underlying filesystem supports them.
3011 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
3013 Fix macroexp crash on Windows with debugging (Bug#12118).
3014 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
3015 checking subscripts; problem introduced with the recent
3016 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
3017 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
3018 since it's used in non-static inline functions now.
3020 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
3021 Don't assume buffer size fits in 'int'. Remove unused local.

3041 * composite.c (COMPOSITE_INLINE):
3042 * dispnew.c (DISPEXTERN_INLINE):
3043 * sysdep.c (SYSTIME_INLINE):
3044 Define to EXTERN_INLINE, so that the corresponding functions
3045 are compiled into code.
3046 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
3047 (INLINE_HEADER_END): New macros.
3048 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

3068 hard-coding the path separator.
3070 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
3072 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
3073 This how ASET and AREF are supposed to work, and makes
3074 it easier to think about future improvements. See
3075 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
3076 * charset.h (set_charset_attr): New function.

3564 Fix export of symbols to GDB (Bug#12036).
3565 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
3566 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
3567 emacs.c, as this is a more-suitable home. Had this been done earlier
3568 the fix for 12036 would have avoided some of the problems noted in
3569 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
3570 would have been more obvious.
3571 * emacs.c: Do not include <verify.h>; no longer needed.
3572 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
3573 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
3574 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3575 Remove; now done in lisp.h.
3576 * lisp.h (PUBLISH_TO_GDB): New macro.
3577 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
3578 (DATA_SEG_BITS): Use it.
3579 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
3580 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3581 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3582 not be usable in #if. This simplifies things.
3584 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
3586 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
3588 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
3590 Simplify export of symbols to GDB (Bug#12036).
3591 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3592 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3593 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3594 Adjust to changes in lisp.h and emacs.c, by using
3595 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
3596 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
3597 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
3598 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
3599 instead of gdb_valbits.
3600 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
3601 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
3602 instead of gdb_array_mark_flag.
3603 (xboolvector): Get size from $->size, not $->header.size.
3604 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
3605 (xreload, hook-run, hookpost-run): Remove.
3606 * emacs.c: Include <verify.h>.
3607 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
3608 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
3610 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
3611 (gdb_USE_LSB_TAG): New enum constants.
3612 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3613 Also define these as enum constants, so they're visible to GDB.
3614 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
3615 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
3616 as constants, so they're visible to GDB.
3617 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
3618 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
3619 Now enum constants, not macros, so they're visible to GDB.
3620 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
3621 more convenient now. All uses changed.
3622 (VALMASK) [USE_LSB_TAG]: Also define in this case.
3623 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
3625 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
3627 Explicitly free restriction data that are not needed anymore.
3628 * editfns.c (save_restriction_restore): Free restriction data.
3630 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
3632 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
3633 add argument, tune behavior, and adjust all callers.
3635 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
3637 Use typedef for EMACS_INT, EMACS_UINT.
3638 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
3639 than macros. This simplifies debugging in the usual case, since
3640 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
3641 and it allows expressions involving EMACS_INT casts.
3642 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
3644 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
3646 * nsterm.m (ns_read_socket): Return early if there is a modal

3654 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
3656 Adjust buffer text indirection counters at the end of Fkill_buffer.
3657 * buffer.c (Fkill_buffer): Adjust indirection counters when the
3658 buffer is definitely dead. This should really fix an issue reported
3659 by Christoph Scholtes again. (Bug#12007).
3660 (init_buffer_once): Initialize indirection counters of
3661 buffer_defaults and buffer_local_symbols (for sanity and safety).
3663 2012-07-24 Eli Zaretskii <eliz@gnu.org>
3665 * xdisp.c (init_iterator): Don't compute dimensions of truncation
3666 and continuation glyphs on tooltip frames, leave them at zero.
3667 Avoids continued lines in tooltips. (Bug#11832)
3669 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
3671 Simplify copy_overlay.
3672 * buffer.c (copy_overlay): Simplify. Use build_marker.

3678 or invalid. (Bug#12025)
3680 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
3681 it signals an error when a tooltip frame is being created.
3683 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3685 Cleanup miscellaneous objects allocation and initialization.
3686 * alloc.c (allocate_misc): Change to static. Add argument to
3687 specify the subtype. Adjust comment and users.
3688 (build_overlay): New function.
3689 * buffer.c (copy_overlays, Fmake_overlay): Use it.
3690 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.

3692 (build_overlay): Add prototype.
3694 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3696 Swap buffer text indirection counters in Fbuffer_swap_text.
3697 * buffer.c (Fbuffer_swap_text): Swap indirections too.
3698 This avoids crash reported by Christoph Scholtes at
3699 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
3701 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
3703 * nsmenu.m (Popdown_data): New struct.
3704 (pop_down_menu): p->pointer is Popdown_data. Release the pool and

3708 and autorelease them. Also autorelease img and matrix (Bug#12005).
3709 (dealloc): Remove (Bug#12005).

3726 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
3728 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
3729 as it's limited by the amount of memory, not by INT_MAX.
3731 2012-07-21 Eli Zaretskii <eliz@gnu.org>
3733 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
3734 in special-event-map. See the discussion at

3869 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
3871 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug

3884 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3886 * eval.c (Fdefvar): Don't check constants since we only set the var if
3887 it's not yet defined anyway (bug#11904).
3889 * lisp.h (last_undo_boundary): Declare new var.
3890 * keyboard.c (command_loop_1): Set it.
3891 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
3892 were auto-added by the command loop (bug#11774).
3894 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>

4462 The functional style also makes code easier to read and maintain.
4463 * systime.h: Include <sys/time.h> on all hosts, not just if
4464 WINDOWSNT, since 'struct timeval' is needed in general.
4465 (EMACS_TIME): Now a typedef, not a macro.
4466 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
4468 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
4469 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
4470 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
4471 (EMACS_TIME_LE): Now functions, not macros.
4472 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
4473 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
4474 which are not functions. All uses rewritten to use:
4475 (make_emacs_time): New function.
4476 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
4477 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4478 not functions. All uses rewritten to use the following, respectively:
4479 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
4480 (add_emacs_time, sub_emacs_time): New functions.
4481 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
4482 * fileio.c (Fcopy_file):
4483 * xterm.c (XTflash): Get the current time closer to when it's used.
4484 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

4491 * frame.c (Fmake_terminal_frame):
4492 * gtkutil.c (get_utf8_string):
4494 * nsmenu.m (ns_update_menubar):
4495 * regex.c (regerror):
4496 Prefer memcpy to strncpy and strncat when either will do.

4498 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
4499 (menu_separator_name_p):
4500 * nsmenu.m (ns_update_menubar):
4501 Prefer memcmp to strncmp when either will do.
4502 * nsterm.m: Include <ftoastr.h>.
4504 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
4505 Prefer snprintf to strncpy.
4506 * nsterm.m (ns_term_init):
4507 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4508 * nsterm.m (ns_term_init):
4509 Avoid the need for strncpy, by using build_string or
4510 make_unibyte_string directly. Use dtoastr, not snprintf.
4511 * process.c (Fmake_network_process): Diagnose service names that
4512 are too long, rather than silently truncating them or creating
4513 non-null-terminated names.
4514 (Fnetwork_interface_info): Likewise, for interface names.
4515 * sysdep.c (system_process_attributes) [GNU_LINUX]:
4516 Prefer sprintf to strncat.
4517 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
4518 Prefer vsnprintf to vsprintf + strncpy.
4520 2012-07-10 Glenn Morris <rgm@gnu.org>
4522 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
4523 Clarify fallback case.
4525 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4527 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
4528 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
4529 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
4530 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
4531 where argument type is known to be a Lisp_Cons.

4543 Optimize pure C strings initialization.
4544 * lisp.h (make_pure_string): Fix prototype.
4545 (build_pure_c_string): New function, defined as static inline. This
4546 provides a better opportunity to optimize away calls to strlen when
4547 the function is called with compile-time constant argument.
4548 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
4549 argument, adjust users accordingly. Use build_pure_c_string where
4551 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
4552 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
4553 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
4555 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4557 Avoid calls to strlen in miscellaneous functions.
4558 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
4559 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
4560 * lread.c (openp): Likewise.
4562 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4564 Avoid calls to strlen in path processing functions.
4565 * fileio.c (file_name_as_directory): Add comment. Change to add
4566 srclen argument and return the length of result. Adjust users
4568 (directory_file_name): Fix comment. Change to add srclen argument,
4569 swap 1st and 2nd arguments to obey the common convention.
4570 Adjust users accordingly.
4571 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
4573 2012-07-10 Glenn Morris <rgm@gnu.org>
4575 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
4576 Move PENDING_OUTPUT_COUNT definition to configure.
4578 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
4579 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
4580 * s/gnu.h (DATA_START): Move definitions to configure.
4582 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
4583 We include usg5-4-common.h, which defines them both.
4585 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
4586 O_RDONLY already includes it).
4588 Stop ns builds setting the EMACSLOADPATH environment variable.
4589 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4590 Now it does not set EMACSLOADPATH, just returns the load-path string.
4591 * nsterm.h: Update accordingly.
4592 * lread.c [HAVE_NS]: Include nsterm.h.
4593 (init_lread) [HAVE_NS]: Use ns_load_path.
4594 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
4596 2012-07-09 Glenn Morris <rgm@gnu.org>
4598 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
4599 since the included bsd-common.h does so.
4601 Stop ns builds setting the EMACSPATH environment variable.
4602 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
4603 (ns_init_paths): Do not set EMACSPATH.
4604 * nsterm.h (ns_exec_path): Add it.
4605 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
4608 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
4610 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
4612 * process.c (wait_reading_process_output): 'waitchannels' was unset
4613 when read_kbd || !NILP (wait_for_cell); fix this.
4615 Add GCC-style 'const' attribute to functions that can use it.
4616 * character.h (char_resolve_modifier_mask):
4617 * keyboard.h (make_ctrl_char):
4618 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
4619 (init_character_once, next_almost_prime, init_fns, init_image)
4620 (flush_pending_output, init_sound):
4621 * mem-limits.h (start_of_data):
4622 * menu.h (finish_menu_items):

4625 Declare the dummy function with ATTRIBUTE_CONST.
4626 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
4627 Add decls with ATTRIBUTE_CONST.
4629 Minor improvements to make_formatted_string.
4630 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
4631 where int is good enough, as vsprintf returns an int.
4632 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
4634 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4636 Use make_formatted_string to avoid double length calculation.
4637 * lisp.h (make_formatted_string): New prototype.
4638 * alloc.c (make_formatted_string): New function.
4639 * buffer.c (Fgenerate_new_buffer_name): Use it.
4640 * dbus.c (syms_of_dbusbind): Likewise.

4642 * filelock.c (get_boot_time): Likewise.
4643 * frame.c (make_terminal_frame, set_term_frame_name)
4644 (x_report_frame_params): Likewise.
4645 * image.c (gs_load): Likewise.
4646 * minibuf.c (get_minibuffer): Likewise.

4661 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4663 Move marker debugging code under MARKER_DEBUG.
4664 * marker.c (MARKER_DEBUG): Move marker debugging code under
4665 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4666 for bootstrap with --enable-checking (~3x slowdown reported
4667 by Juanma Barranquero <lekktu@gmail.com>).
4668 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4670 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4672 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
4673 See <http://bugs.gnu.org/11825#29>.
4675 2012-07-08 Eli Zaretskii <eliz@gnu.org>
4677 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4678 has no font, use the frame's font. (Bug#11813)
4679 (display_line): Add commentary about displaying truncation glyphs
4681 (produce_special_glyphs): Move here from term.c.
4683 * term.c (produce_special_glyphs): Move to xdisp.c.
4685 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4688 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4690 * xdisp.c (display_line): Avoid warning about implicit declaration
4693 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4695 * lisp.h: Remove empty conditional.
4697 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4699 * lread.c (load_path_check): Now static.
4701 Fix some minor --with-ns problems found by static checking.
4702 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
4703 (x_set_font) [!HAVE_X_WINDOWS]:
4704 * image.c (xpm_load_image) [HAVE_NS]:
4705 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4706 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4707 Remove unused local.
4708 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
4709 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
4710 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
4711 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
4712 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
4713 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
4714 Fix pointer signedness problem.
4715 * xfaces.c (FRAME_X_FONT_TABLE):
4716 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
4718 2012-07-07 Glenn Morris <rgm@gnu.org>
4720 * lread.c (load_path_check): New function, split from init_lread.
4721 (init_lread): Reorganize. Motivation:
4722 If EMACSLOADPATH is set, check/warn about that rather than the
4723 defaults, which we are not going to use. Hence we can remove
4724 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4725 Don't warn if site-lisp directories are missing.
4726 If not installed, start from a blank load-path, since
4727 PATH_LOADSEARCH refers to the eventual installation directories.
4729 2012-07-07 Eli Zaretskii <eliz@gnu.org>
4731 Support truncation and continuation glyphs on GUI frames, when
4732 fringes are disabled. (Bug#11832)
4733 * xdisp.c (init_iterator): Get dimensions of truncation and
4734 continuation glyphs even if on GUI frames.
4735 Adjust it->last_visible_x on GUI frames when the left or right fringes,
4736 or both, are absent.
4737 (start_display, move_it_in_display_line_to): Handle the case of a
4738 GUI frame without a fringe to display continuation or truncation
4740 (insert_left_trunc_glyphs): Support GUI frames: make sure
4741 truncation glyphs overwrite enough glyphs from the current line to
4742 have sufficient space in pixels.
4743 (display_line): Support truncation and continuation glyphs on GUI
4744 frames. If some spare pixels are left on the line after inserting
4745 the truncation glyphs, fill that space with a stretch glyph of a
4746 suitably computed width.
4748 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4749 produce_glyphs, to support GUI sessions.
4751 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4753 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4755 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4757 Do not require float-time's arg to fit in time_t (Bug#11825).
4758 This works better on hosts where time_t is unsigned, and where
4759 float-time is applied to the (negative) difference between two times.
4760 * editfns.c (decode_time_components): Last arg is now double *,
4761 not int *, and means to store all the result as a double, without
4762 worrying about whether the seconds part fits in time_t.
4763 All callers changed.
4764 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4765 All callers changed.
4766 (Ffloat_time): Do not fail merely because the specified time falls
4767 outside of time_t range.
4769 2012-07-07 Glenn Morris <rgm@gnu.org>
4771 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
4772 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
4773 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
4775 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
4777 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
4778 Update dependencies.
4780 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
4782 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4784 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
4785 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
4786 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
4787 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
4788 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
4789 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
4791 * xfont.c (compare_font_names): Redo to omit the need for casts.
4793 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4795 * xfns.c (Fx_change_window_property): Doc fix.
4796 * w32fns.c (Fx_change_window_property): Doc fix.
4798 * w32fns.c (Fx_window_property): Accept the same arguments as the
4799 X Windows version. Doc fix.
4800 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4802 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4803 Eli Zaretskii <eliz@gnu.org>
4805 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4806 Windows-specific code from nt/config.nt moved here.
4807 Obsolete settings removed.
4809 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4811 * process.c: Avoid unnecessary calls to gettime.
4812 (wait_reading_process_output): Don't get the time of day
4813 when gobbling data immediately and not waiting, as there's no need
4814 for it in that case. This removes a FIXME.
4816 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4818 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4819 is defined (Bug#11768).
4821 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4823 Fix marker debugging code.
4824 * marker.c (byte_char_debug_check): Do not perform the check
4825 if buffer is not multibyte.
4826 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4827 Call byte_char_debug_check with correct arguments.
4829 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4831 Compile marker debugging code only if ENABLE_CHECKING is defined.
4832 * marker.c (byte_char_debug_check, count_markers):
4833 Use only if ENABLE_CHECKING is defined.
4834 (byte_debug_flag): Remove.
4835 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4836 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4838 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4840 Avoid code repetition in marker-related functions.
4841 * marker.c (attach_marker): New function.
4842 (Fset_marker, set_marker_restricted, set_marker_both)
4843 (set_marker_restricted_both): Use it.
4844 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4845 Consistently rename charno to charpos.
4846 (marker_position): Add eassert.
4847 (marker_byte_position): Convert to eassert.
4849 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4851 Simplify list operations in unchain_overlay and unchain_marker.
4852 * buffer.c (unchain_overlay): Simplify. Add comment.
4853 * marker.c (unchain_marker): Simplify. Fix comments.

4865 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
4866 * window.c (save_window_save): Likewise.
4868 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4870 Do not use Fdelete_overlay in delete_all_overlays
4871 to avoid redundant calls to unchain_overlay.
4872 * buffer.c (drop_overlay): New function.
4873 (delete_all_overlays, Fdelete_overlay): Use it.
4874 * minibuf.c (get_minibuffer): Fix comment.
4876 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4878 Port to OpenBSD 5.1 amd64.
4879 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4880 This is needed for OpenBSD, and should be harmless on all BSD systems.
4881 Also, include <sys/sysctl.h>, as it should be available on all
4882 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4883 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4884 use p_pid member, not kp_proc.pid.
4886 2012-07-06 Glenn Morris <rgm@gnu.org>
4888 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4890 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4892 More xmalloc and related cleanup.
4893 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
4894 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

4901 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4903 Omit needless casts involving void * pointers and allocation.
4904 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4905 as the former is more robust if P's type is changed.
4906 Prefer xzalloc to xmalloc + memset 0.
4907 Simplify malloc-or-realloc to realloc.
4908 Don't worry about xmalloc returning a null pointer.
4909 Prefer xstrdup to xmalloc + strcpy.
4910 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4912 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4913 alloca of a constant.
4915 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4917 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4918 hscroll is larger than the line width. Fixes long and futile
4919 looping inside extend_face_to_end_of_line (on a TTY) producing
4920 glyphs that are not needed and thrown away.
4922 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4924 * marker.c (set_marker_restricted_both): Simplify by using

4929 * editfns.c (region_limit): Simplify by using clip_to_bounds.
4931 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
4933 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
4934 not defined (Bug#11768).
4935 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
4936 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
4937 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
4938 followed by gtk_box_set_homogeneous (Bug#11768).
4939 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4940 (update_theme_scrollbar_width, xg_create_scroll_bar):
4941 Use gtk_scrollbar_new (Bug#11768).
4942 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

4950 * xdisp.c (window_hscroll_limited): New function.
4951 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
4952 coordinates when window's hscroll is set to insanely large
4955 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
4957 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

5018 * fileio.c (time_error_value): Check the right error number.
5019 Problem reported by Troels Nielsen in
5020 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
5022 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5024 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
5025 This should be fixed in a better way; see Eli Zaretskii in
5026 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
5027 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
5029 * fileio.c (time_error_value): Rename from special_mtime.
5030 The old name's problems were noted by Eli Zaretskii in
5031 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
5033 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
5034 This variable's comment says Emacs needs at least one GDB-visible
5035 symbol of type enum pvec_type, to work around GDB problems.
5036 The symbol's value doesn't matter.
5038 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
5039 that causes compilation to fail on pre-C99 compilers.
5041 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
5043 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

5046 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5048 * buffer.c (init_buffer_once): Fix initialization of
5049 headers for buffer_defaults and buffer_local_symbols.
5050 Reported by Juanma Barranquero <lekktu@gmail.com>.
5052 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
5054 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
5055 * lisp.h (enum pvec_type): Use fewer bits.
5056 (PSEUDOVECTOR_SIZE_BITS): New constant.
5057 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
5058 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
5059 change in pvec_type.
5060 (PSEUDOVECTOR_TYPEP): New macro.
5061 (TYPED_PSEUDOVECTORP): Use it.
5062 * fns.c (internal_equal): Adapt code to extract pvectype.

5066 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
5067 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
5068 (sweep_vectors): Use it. Use local var `total_bytes' instead of
5069 abusing vector->header.next.nbytes.
5070 (live_vector_p): Use PVEC_TYPE.
5071 (mark_object): Adapt code to extract pvectype. Use switch.
5073 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5075 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
5076 Tighten new eassert a bit.
5078 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5080 Fix compilation with --enable-gcc-warnings and -O1
5082 * doprnt.c (doprnt): Change type of tem to int, initialize
5083 to avoid compiler warning. Add eassert.
5084 * search.c (simple_search): Initialize match_byte to avoid
5085 compiler warning. Add eassert.
5087 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5089 Avoid weird behavior with large horizontal scrolls.
5090 Without this change, for example, large hscroll values would
5091 mess up Emacs's display on Fedora 15 x86, presumably due to
5092 overflows in int calculations in the display code.
5093 Also, if buffers had long lines, Emacs would freeze.
5094 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
5095 (set_window_hscroll): New function, containing the old guts of
5096 Fset_window_hscroll. Return the clipped value.
5097 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
5098 This avoids the need to check against PTRDIFF_MAX.
5100 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
5102 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5104 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
5106 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5108 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
5109 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
5110 since GCC 4.4.6 issues a bogus warning for them.
5112 Fix bugs in file timestamp newness comparisons.
5113 * fileio.c (Ffile_newer_than_file_p):
5114 * lread.c (Fload): Use full timestamp resolution of files,
5115 not just the 1-second resolution, so that files that are only
5116 slightly newer still count as newer.
5117 * fileio.c (Ffile_newer_than_file_p): Don't assume file
5118 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
5120 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
5122 * fileio.c: Improve handling of file time marker. (Bug#11852)
5123 (special_mtime): New function.
5124 (Finsert_file_contents, Fverify_visited_file_modtime):
5125 Use it to set special mtime values consistently.
5127 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
5129 * fileio.c (Finsert_file_contents): Properly handle st_mtime
5130 marker for non-existing file. (Bug#11852)
5132 2012-07-03 Glenn Morris <rgm@gnu.org>
5134 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
5135 and did not make it into globals.h).
5137 2012-07-03 Tom Tromey <tromey@redhat.com>
5139 * window.c (Fset_window_margins, Fset_window_fringes)
5140 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
5141 * textprop.c (Fprevious_property_change): No longer static.

5164 * intervals.h: Remove EXFUNs.
5165 * fontset.h: Remove EXFUN.

5170 * w32term.h: Remove EXFUNs.
5171 * window.h: Remove EXFUNs.
5172 * xsettings.h: Remove EXFUN.
5173 * xterm.h: Remove EXFUN.
5175 2012-07-03 Glenn Morris <rgm@gnu.org>
5177 * lisp.h (Frandom): Make it visible to C.
5178 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
5179 buffer for invisible buffers. (Bug#1229)
5181 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5183 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
5184 values which aren't power of 2.
5185 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
5186 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
5189 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
5191 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
5193 * alloc.c (mark_object): Revert part of last patch to use `switch'.
5195 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5197 * alloc.c (allocate_vector_block): Remove redundant
5198 calls to mallopt if DOUG_LEA_MALLOC is defined.
5199 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
5200 avoid calls to mallopt if zero_vector is returned.
5202 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5204 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
5205 is enabled, avoid dereferencing NULL current_sblock if
5208 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5210 Cleanup basic buffer management.
5211 * buffer.h (struct buffer): Change layout to use generic vector
5212 marking code. Fix some comments. Change type of 'clip_changed'
5213 to bitfield. Remove unused #ifndef old.
5214 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
5215 (GET_OVERLAYS_AT): Fix indentation.
5216 (for_each_per_buffer_object_at): New macro.
5217 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

5219 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
5220 * alloc.c (allocate_buffer): Adjust to match new layout of
5221 struct buffer. Fix comment.
5222 (mark_overlay): New function.

5224 Lisp area of struct buffer.
5225 (mark_object): Use it. Adjust marking of misc objects
5226 and related comments.
5228 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
5230 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
5231 wrapper that is not needed because the wrapped code is a no-op (zero
5232 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
5233 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
5235 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
5237 * alloc.c (mark_buffer): Simplify. Remove prototype.
5238 (mark_object): Add comment. Reorganize marking of vector-like
5239 objects. Use CHECK_LIVE for all vector-like objects except buffers
5240 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
5241 Avoid redundant calls to mark_vectorlike for bool vectors.
5243 2012-06-30 Glenn Morris <rgm@gnu.org>
5245 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
5247 * epaths.in (PATH_SITELOADSEARCH): New.
5248 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
5249 This is rather than relying on --enable-locallisppath elements
5250 having "site-lisp" in their names. (Bug#10208#25, 11658)
5252 2012-06-30 Eli Zaretskii <eliz@gnu.org>
5254 * w32proc.c (sys_select): Accept and ignore one more argument.
5256 * w32.c (emacs_gnutls_pull): Call select with one more argument.
5258 * sysselect.h [DOS_NT]: Don't include sys/select.h.
5259 (pselect) [!MS_DOS]: Redirect to sys_select.
5261 * sysdep.c: Don't include dos.h and dosfns.h.
5263 * process.c (sys_select):
5264 * msdos.c (sys_select): Accept one more argument and ignore it.
5266 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
5267 adapt data types and code to that.
5270 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
5271 which clashes with the gnulib function of the same name.
5273 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
5275 * font.c (font_style_to_value, font_style_symbolic)
5276 (font_prop_validate_style): Add type checks for values in
5279 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
5281 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
5284 2012-06-29 Eli Zaretskii <eliz@gnu.org>
5286 * xdisp.c (try_window_id): Undo last change.
5288 * w32.c (getwd): Adjust commentary about startup_dir.
5289 (init_environment): Always call sys_access, even in non-MSVC
5290 builds. Don't chdir to the directory of the Emacs executable.
5291 This undoes code from 1997 which was justified by the need to
5292 "avoid conflicts when removing and renaming directories". But its
5293 downside was that every relative file name was being interpreted
5294 relative to the directory of the Emacs executable, which can never
5295 be TRT. In particular, it broke sys_access when called with
5296 relative file names.
5297 (sys_access): Map GetLastError to errno.
5299 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5301 * window.h (struct window): Change type of 'fringes_outside_margins'

5305 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
5308 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
5310 * gnutls.c (emacs_gnutls_handshake):
5311 Add QUIT to make the loop interruptible.
5313 2012-06-29 Glenn Morris <rgm@gnu.org>
5315 * charset.c (init_charset): Make lack of etc/charsets fatal.
5317 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5319 * editfns.c (region_limit): Fix type mismatch.
5321 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5323 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
5324 undefined. Convert from xassert to eassert.
5325 * nsmenu.m: Convert from xassert to eassert.
5326 * nsterm.m: Likewise.
5328 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
5330 * editfns.c (region_limit): Clip to narrowing (bug#11770).
5332 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
5334 Avoid integer overflow on scroll-left and scroll-right.
5335 * window.c (HSCROLL_MAX): New macro.
5336 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
5337 overflow when requested scroll falls outside ptrdiff_t range.
5339 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
5341 * window.h (struct window): Change type of 'hscroll',
5342 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
5343 'last_modified' and 'last_overlay_modified' to EMACS_INT.
5344 Adjust users accordingly.
5345 * xdisp.c (try_cursor_movement): Replace type check with eassert.
5346 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
5347 from EMACS_INT to ptrdiff_t.
5348 (make_window): Omit redundant initialization.
5350 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
5352 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
5354 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
5356 * window.h (struct window): Change type of 'use_time' and
5357 'sequence_number' from Lisp_Object to int.
5358 * frame.c (make_frame): Adjust users accordingly.
5359 * print.c (print_object): Likewise.
5360 * window.c (select_window, Fwindow_use_time, make_parent_window)
5361 (make_window): Likewise.
5363 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
5365 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
5366 enabled with --enable-checking=[all,glyphs] configure option.
5367 Fix GLYPH_DEBUG usage assuming that it may be undefined,
5368 adjust comments accordingly.
5369 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
5370 undefined, adjust comments accordingly.

5491 Use sprintf return value instead of invoking strlen on result.
5492 In the old days this wasn't portable, since some sprintf
5493 implementations returned char *. But they died out years ago and
5494 Emacs already assumes sprintf returns int.
5495 Similarly for float_to_string.
5496 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

5504 Use sprintf or float_to_string result to avoid need to call strlen.
5505 * data.c (Fnumber_to_string):
5506 Use make_unibyte_string, since the string must be ASCII.
5507 * lisp.h, print.c (float_to_string): Now returns int length.
5508 * term.c (produce_glyphless_glyph):
5509 Use sprintf result rather than recomputing it.
5511 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
5512 * Makefile.in (ALL_CFLAGS):

5544 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

5549 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
5550 instead of truncating it to 63 (admittedly a generous limit).

5610 * keyboard.c (kbd_buffer_get_event):
5611 * process.c (Faccept_process_output):
5612 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
5613 This improves on the previous patch, which introduced a bug
5614 when time_t is unsigned and as wide as intmax_t.
5615 See <http://bugs.gnu.org/9000#51>.
5617 2012-06-23 Eli Zaretskii <eliz@gnu.org>

5646 language ID in the event parameters.
5648 * w32term.c (w32_read_socket): Put the new keyboard codepage into

5680 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5682 Support higher-resolution time stamps (Bug#9000).
5683 The time stamps are only nanosecond-resolution at the C level,
5684 since that's the best that any real-world system supports now.
5685 But they are picosecond-resolution at the Lisp level, as that's
5686 easy, and leaves room for future OS improvements.
5688 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5691 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5692 Don't get current time unless it's needed.
5694 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5695 now provides it if it's absent.
5696 (start_atimer): Port to higher-res time stamps.
5697 Check for time stamp overflow. Don't get current time more
5698 often than is needed.
5700 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5701 Include systime.h, not time.h.
5702 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
5704 * dired.c: Include stat-time.h.
5705 (Ffile-attributes): File times now have higher resolution.
5707 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
5708 (struct image): Timestamp now has higher resolution.
5710 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5711 has at least microseconds now. All uses removed.
5712 (update_frame, update_single_window, update_window, update_frame_1)
5713 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5714 (duration_to_sec_usec): Remove; no longer needed.
5716 * editfns.c (time_overflow): Now extern.
5717 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
5718 (float-time, Fformat_time_string, Fcurrent_time_string)

5721 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
5722 (decode_time_components, lisp_seconds_argument): New functions.
5723 (make_time): Now static.
5724 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
5725 Report an error if the time is invalid, rather than having the caller
5728 * fileio.c: Include <stat-time.h>
5729 (Fcopy_file): Copy higher-resolution time stamps.
5730 Prefer to set the time stamp via a file descriptor if that works.
5731 (Fset_file_times, Finsert_file_contents, Fwrite_region)
5732 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
5733 (Fvisited_file_modtime, Fset_visited_file_modtime):
5734 Support higher-resolution time stamps.
5736 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
5738 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
5740 * image.c (prepare_image_for_display, clear_image_cache)
5741 (lookup_image): Port to higer-resolution time stamps.
5743 * keyboard.c (start_polling, bind_polling_period):
5744 Check for time stamp overflow.
5745 (read_char, kbd_buffer_get_event, timer_start_idle)
5746 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
5747 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5748 Port to higher-resolution time stamps. Do not assume time_t is signed.
5749 (decode_timer): New function. Timers are now vectors of length 9,
5750 not 8, to accommodate the picosecond component.
5751 (timer_check_2): Use it.
5753 * nsterm.m (select_timeout, timeval_subtract): Remove.
5754 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5755 as they're a bit more accurate and handle overflow better.
5756 (ns_select): Change prototype to be compatible with pselect.
5757 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5758 * nsterm.h (ns_select): Adjust prototype.
5760 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5761 us-resolution time stamps.
5762 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5764 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5766 * lisp.h (time_overflow): New decl.
5767 (wait_reading_process_output): First arg is now intmax_t, not int,
5768 to accommodate larger waits.
5770 * process.h (struct Lisp_Process.read_output_delay):
5771 Now counts nanoseconds, not microseconds.
5772 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
5774 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
5775 (wait_reading_process_output):
5776 Port to ns-resolution time stamps.
5777 (Faccept_process_output, wait_reading_process_output):
5778 Check for time stamp overflow. Do not assume time_t is signed.
5779 (select_wrapper): Remove; we now use pselect.
5780 (Fprocess_attributes): Now generates ns-resolution time stamps.
5782 * sysdep.c: Include utimens.h. Don't include utime.h
5783 or worry about struct utimbuf; gnulib does that for us now.
5784 (gettimeofday): Remove; gnulib provides a substitute.
5785 (make_timeval): New function.
5786 (set_file_times): Now sets ns-resolution time stamps.
5787 New arg FD; all uses changed.
5788 (time_from_jiffies, ltime_from_jiffies, get_up_time)
5789 (system_process_attributes):
5790 Now returns ns-resolution time stamp. All uses changed.
5791 Check for time stamp overflow.
5793 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5794 provides a substitute now.
5796 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5797 since it guarantees struct timespec.
5798 (EMACS_TIME): Now struct timespec, so that we can support
5799 ns-resolution time stamps.
5800 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5801 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5802 (EMACS_USECS): Remove.
5803 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5804 so multiply the arg by 1000 before storing it.
5805 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
5807 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
5808 Port to ns-resolution time stamps.
5809 (EMACS_TIME_NEG_P): Remove; replaced by....
5810 (EMACS_TIME_SIGN): New macro.
5811 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
5812 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
5813 (set_file_times, make_time, lisp_time_argument): Adjust signature.
5814 (make_timeval, make_lisp_time, decode_time_components): New decls.
5815 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
5816 that it mishandled time_t overflow. You can't compare by subtracting!
5817 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
5818 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
5820 * term.c: Include <sys/time.h>.
5821 (timeval_to_Time): New function, for proper overflow wraparound.
5822 (term_mouse_position, term_mouse_click): Use it.
5824 * undo.c (record_first_change): Support higher-resolution time stamps
5826 (Fprimitive_undo): Use them when restoring time stamps.
5828 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
5829 (w32_get_internal_run_time):
5830 Port to higher-resolution Emacs time stamps.
5831 (ltime): Now accepts single 64-bit integer, as that's more convenient
5834 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
5836 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
5837 for compatibility with pselect. Support ns-resolution time stamps.
5839 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
5841 * xselect.c (wait_for_property_change, x_get_foreign_selection):
5842 Check for time stamp overflow, and support ns-resolution time stamps.
5844 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
5845 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
5846 (timeval_subtract): Remove; no longer needed.
5847 (XTflash, XTring_bell, x_wait_for_event):
5848 Port to ns-resolution time stamps. Don't assume time_t is signed.
5850 2012-06-22 Chong Yidong <cyd@gnu.org>
5852 * xdisp.c (x_consider_frame_title): Revert last change.
5854 2012-06-22 Eli Zaretskii <eliz@gnu.org>
5856 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
5857 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER

6131 code works fine either way, and efficiency is not a concern here,
6132 as the union type is for debugging, not for production.
6133 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
6134 Use an inline function on all platforms when using the union type,
6135 since this is simpler and 'static inline' can be used portably

6279 * doprnt.c (doprnt): Truncate multibyte char correctly.
6280 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
6281 would mishandle a string argument "Xc" if X was a multibyte
6282 character of length 2: it would truncate after X's first byte
6283 rather than including all of X.

6336 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
6337 Convert pctcpu and pctmem to Lisp float properly.
6338 Let the compiler fold better, as 100.0/0x8000 is exact.
6340 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
6342 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
6345 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
6347 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
6349 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
6351 For a 'struct window', replace some Lisp_Object fields to
6352 bitfields where appropriate, remove unused fields.
6353 * window.h (struct window): Remove unused 'last_mark_x' and
6354 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
6355 change it's type from Lisp_Object to bitfield.
6356 Change type of 'force_start', 'optional_new_start',
6357 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
6358 fields from Lisp_Object to bitfield. Adjust users accordingly.
6360 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6362 Pacify gcc -Wdouble-precision when using Xaw.
6363 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
6364 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
6365 Use 'float' consistently, rather than 'float' in most places
6366 and 'double' in a couple of places.
6368 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6370 * xdisp.c (handle_stop): Detect whether we have overlay strings
6371 loaded by testing it->current.overlay_string_index to be
6372 non-negative, instead of checking whether n_overlay_strings is
6373 positive. (Bug#11587)
6375 2012-05-31 Chong Yidong <cyd@gnu.org>
6377 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
6379 * doc.c (Fsubstitute_command_keys): Doc fix.
6381 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6383 * search.c (search_buffer): Remove calls to
6384 r_alloc_inhibit_buffer_relocation, as it is now called by
6385 maybe_unify_char, which was the cause of relocation of buffer text
6388 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6390 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6391 for the duration of call to load_charset, to avoid problems with
6392 callers of maybe_unify_char that access buffer text through C
6395 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6396 decrement the inhibition flag, instead of just setting or
6399 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6401 Remove obsolete '#define static' cruft.
6402 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6403 This #undef was "temporary" in 2000; it is no longer needed
6404 now that '#define static' has gone away.
6405 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6406 (gray_bitmap_bits): Remove; no longer needed.
6407 All uses replaced with definiens.
6408 * xterm.c: Include "bitmaps/gray.xbm".
6410 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6412 Clean up __executable_start, monstartup when --enable-profiling.
6413 The following changes affect the code only when profiling.
6414 * dispnew.c (__executable_start): Rename from safe_bcopy.
6415 Define only on platforms that need it.
6416 * emacs.c: Include <sys/gmon.h> when profiling.
6417 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6418 (__executable_start): Remove decl, since lisp.h does it now.
6419 (safe_bcopy): Remove decl; no longer has that name.
6420 (main): Coalesce #if into single bit of code, for simplicity.
6421 Cast pointers to uintptr_t, since standard libraries want integers
6423 * lisp.h (__executable_start): New decl.
6425 2012-05-31 Glenn Morris <rgm@gnu.org>
6427 * image.c (Fimagemagick_types): Doc fix.
6429 2012-05-30 Jim Meyering <meyering@redhat.com>
6431 * callproc.c (Fcall_process_region): Include directory component
6432 in mkstemp error message (Bug#11586).
6434 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6436 * alloc.c, lisp.h (make_pure_vector): Now static.
6438 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

6443 * data.c (Fdefalias): Purify definition, except for keymaps.
6444 (Qdefun): Move from eval.c.
6445 * lisp.h (Qdefun): Remove.
6446 * lread.c (read1): Tiny simplification.
6448 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
6450 Do not create empty overlays with the evaporate property (Bug#9642).
6451 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6452 Bug#9642, but explicitly check that the buffer the overlay would
6453 be moved to is live and rearrange lines to make sure that errors
6454 will not put the overlay in an inconsistent state.
6455 (Fdelete_overlay): Cosmetics.
6457 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6459 * w32term.c (my_bring_window_to_top): New function.
6460 (x_raise_frame): Use handle returned by DeferWindowPos, which
6461 could be different from the original one.
6462 Call my_bring_window_to_top instead of my_set_foreground_window.
6465 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6466 by calling BringWindowToTop.
6468 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6469 (WM_EMACS_END): Increase by one.
6471 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6473 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6474 This avoids undefined behavior that might cause the eassert
6475 to not catch an out-of-range value.
6477 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6479 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
6480 Update dependencies.
6482 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6484 * bidi.c (bidi_mirror_char): Fix last change.
6486 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
6488 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
6489 when referring to sectname field in printf format.
6491 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
6493 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6494 Only r_alloc_inhibit_buffer_relocation needed to be added;
6495 the others were already declared.
6497 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6498 before checking whether it's out of range. Put the check inside
6500 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6502 2012-05-27 Ken Brown <kbrown@cornell.edu>
6504 * callproc.c (Fcall_process): Restore a line that was accidentally
6505 commented out in the 2011-02-13 change (bug#11547).
6507 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6509 * lisp.h [REL_ALLOC]: Add prototypes for external functions
6510 defined on ralloc.c.
6512 * buffer.c [REL_ALLOC]: Remove prototypes of
6513 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
6514 they are now on lisp.h.
6516 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6518 * search.c (search_buffer): Use it to inhibit relocation of buffer
6519 text while re_search_2 is doing its job, because re_search_2 is
6520 passed C pointers to buffer text. (Bug#11519)
6522 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6525 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6526 state after an additional call to move_it_in_display_line_to, keep
6527 the values of it->max_ascent and it->max_descent found for the
6529 (pos_visible_p): Revert the comparison against bottom_y to what it
6530 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
6533 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6535 Fix coding-related core dumps with gcc -ftrapv.
6536 The code was computing A - B, where A and B are pointers, and B is
6537 random garbage. This can lead to core dumps on platforms that
6538 have special pointer registers, and it also leads to core dumps on
6539 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6540 A - B only when B is initialized properly.
6541 * coding.c (coding_set_source, coding_set_destination): Return void.
6542 (coding_change_source, coding_change_destinations): New functions,
6543 with the old behaviors of coding_set_source and coding_set_destination.
6544 All callers that need an offset changed to use these new functions.
6546 2012-05-26 Glenn Morris <rgm@gnu.org>
6548 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
6550 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6552 Extend mouse support on W32 text-mode console.
6553 * xdisp.c (draw_row_with_mouse_face):
6554 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6556 * w32console.c: Include window.h.
6557 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6559 (initialize_w32_display): Initialize mouse-highlight data.
6561 * w32inevt.c: Include termchar.h and window.h.
6562 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6563 moves, call note_mouse_highlight. If help_echo changed, call
6564 gen_help_event to produce help-echo message in the echo area.
6565 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6568 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6570 * lread.c (read1): Simplify slightly to avoid an overflow warning
6571 with GCC 4.7.0 on x86-64.
6573 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6575 * bidi.c (bidi_mirror_char): Revert last change: an int is
6576 definitely wide enough here.
6578 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
6580 Fix integer width and related bugs (Bug#9874).
6581 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
6582 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
6583 (string_bytes, check_sblock, allocate_string_data):
6584 (compact_small_strings, Fmake_bool_vector, make_string)
6585 (make_unibyte_string, make_multibyte_string)
6586 (make_string_from_bytes, make_specified_string)
6587 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
6588 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
6590 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6591 (allocate_pseudovector):
6592 Use int, not EMACS_INT, where int is wide enough.
6593 (inhibit_garbage_collection, Fgarbage_collect):
6594 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6595 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
6596 int might not be wide enough.
6597 (bidi_cache_search, bidi_cache_find, bidi_init_it)
6598 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6599 (bidi_at_paragraph_end, bidi_find_paragraph_start)
6600 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
6601 (bidi_level_of_next_char, bidi_move_to_visually_next):
6602 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6603 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
6604 (Fkill_buffer, Fset_buffer_major_mode)
6605 (advance_to_char_boundary, Fbuffer_swap_text)
6606 (Fset_buffer_multibyte, overlays_at, overlays_in)
6607 (overlay_touches_p, struct sortvec, record_overlay_string)
6608 (overlay_strings, recenter_overlay_lists)
6609 (adjust_overlays_for_insert, adjust_overlays_for_delete)
6610 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
6611 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
6612 (Foverlay_recenter, last_overlay_modification_hooks_used)
6613 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6614 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6615 (validate_region): Omit unnecessary test for b <= e,
6616 since that's guaranteed by the previous test.
6617 (adjust_overlays_for_delete): Avoid pos + length overflow.
6618 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6619 (report_overlay_modification):
6620 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6621 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
6622 Omit pointer cast, which isn't needed anyway, and doesn't work
6623 after the EMACS_INT -> ptrdiff_t change.
6624 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
6625 * buffer.h: Adjust decls to match defn changes elsewhere.
6626 (struct buffer_text, struct buffer):
6627 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6628 Use EMACS_INT, not int, where int might not be wide enough.
6629 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
6630 not int, to avoid needless 32-bit limit on 64-bit hosts.
6631 (exec_byte_code): Use tighter memory-full test, one that checks
6632 for alloca overflow. Don't compute the address of the object just
6633 before an array, as that's not portable. Use EMACS_INT, not
6634 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
6635 * callint.c (Fcall_interactively):
6636 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6637 * callproc.c (call_process_kill, Fcall_process):
6638 Don't assume pid_t fits into an Emacs fixnum.
6639 (call_process_cleanup, Fcall_process, child_setup):
6640 Don't assume pid_t fits into int.
6641 (call_process_cleanup, Fcall_process, delete_temp_file)
6642 (Fcall_process_region):
6643 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6644 (Fcall_process): Simplify handling of volatile integers.
6645 Use int, not EMACS_INT, where int will do.
6646 * casefiddle.c (casify_object, casify_region, operate_on_word)
6647 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
6648 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6649 (casify_object): Avoid integer overflow when overallocating buffer.
6650 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
6651 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
6652 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
6653 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6654 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6655 integers are now checked earlier. All uses replaced with XINT.
6657 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6658 For CCL_MapSingle, check that content and value are in int range.
6659 (ccl_driver, Fregister_code_conversion_map):
6660 Check that Vcode_version_map_vector is a vector.
6661 (resolve_symbol_ccl_program): Check that vector header is in range.
6662 Always copy the vector, so that we can check its contents reliably
6663 now rather than having to recheck each instruction as it's being
6664 executed. Check that vector words fit in 'int'.
6665 (ccl_get_compiled_code, Fregister_ccl_program)
6666 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6667 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
6668 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
6669 contents are in range.
6670 (Fccl_execute_on_string): Check that status is in range.
6671 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
6672 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
6673 Accept and return EMACS_INT, not int, because callers can pass values
6675 (c_string_width, strwidth, lisp_string_width, chars_in_text)
6676 (multibyte_chars_in_text, parse_str_as_multibyte)
6677 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
6678 (str_as_unibyte, str_to_unibyte, string_count_byte8)
6679 (string_escape_byte8, Fget_byte):
6680 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6681 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
6682 avoid mishandling large integers.
6683 * character.h: Adjust decls to match defn changes elsewhere.
6684 * charset.c (load_charset_map_from_file, find_charsets_in_text)
6685 (Ffind_charset_region):
6686 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6687 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
6688 (load_charset_map_from_vector, Fdefine_charset_internal):
6689 Don't assume fixnum fits in int.
6690 (load_charset_map_from_vector, Fmap_charset_chars):
6691 Remove now-unnecessary CHECK_NATNUMs.
6692 (Fdefine_charset_internal): Check ranges here, more carefully.
6693 Don't rely on undefined behavior with signed left shift overflow.
6694 Don't assume unsigned int fits into fixnum, or that fixnum fits
6695 into unsigned int. Don't require max_code to be a valid fixnum;
6696 that's not true for gb10830 4-byte on a 32-bit host. Allow
6697 invalid_code to be a cons, for the same reason. Require code_offset
6698 to be a character. Avoid int overflow if max_char is close
6700 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
6701 this is intended anyway and avoids some undefined behavior.
6702 (load_charset_map): Pass unsigned, not int, as 2nd arg of
6703 INDEX_TO_CODE_POINT, as that's what it expects.
6704 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
6705 * charset.h (DECODE_CHAR): Return int, not unsigned;
6706 this is what was intended anyway, and it avoids undefined behavior.
6707 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
6708 integer-overflow issues.
6709 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
6710 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
6711 where the argument is EMACS_INT, and this behavior is not intended.
6712 * chartab.c (Fmake_char_table, Fset_char_table_range)
6713 (uniprop_get_decoder, uniprop_get_encoder):
6714 Don't assume fixnum fits in int.
6715 * cmds.c (move_point): New function, that does the gist of
6716 Fforward_char and Fbackward_char, but does so while checking
6717 for integer overflow more accurately.
6718 (Fforward_char, Fbackward_char): Use it.
6719 (Fforward_line, Fend_of_line, internal_self_insert)
6720 (internal_self_insert):
6721 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6722 Fix a FIXME, by checking for integer overflow when calculating
6723 target_clm and actual_clm.
6724 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)

7471 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
7473 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
7474 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
7476 2012-05-18 Eli Zaretskii <eliz@gnu.org>
7478 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
7480 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
7481 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
7483 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
7484 reference to image_cache->refcount.
7485 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
7487 2012-05-17 Juri Linkov <juri@jurta.org>
7489 * search.c (Fword_search_regexp, Fword_search_backward)
7490 (Fword_search_forward, Fword_search_backward_lax)
7491 (Fword_search_forward_lax): Move functions to isearch.el
7492 (bug#10145, bug#11381).
7494 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
7496 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
7498 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
7500 * lread.c (init_obarray): Declare Qt and Qnil as special.
7502 2012-05-14 Glenn Morris <rgm@gnu.org>
7504 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
7505 Put "libexec" before "bin", for the sake of init_callproc_1.
7507 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7509 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
7511 * unexaix.c: Port to more-recent AIX compilers.
7512 (report_error, report_error_1, make_hdr, copy_sym)
7513 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
7514 Make arguments const char *, not char *, to avoid violations of C
7515 standard and to fix some AIX warnings reported by Gilles Pion.
7517 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7519 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
7520 already have overlays loaded.
7521 (handle_single_display_spec): Before returning without displaying
7522 fringe bitmap, synchronize the bidi iterator with the main display
7523 iterator, by calling iterate_out_of_display_property.
7524 (iterate_out_of_display_property): Detect buffer iteration by
7525 testing that it->string is a Lisp string.
7526 (get_next_display_element): When the current object is exhausted,
7527 and there's something on it->stack, call set_iterator_to_next to
7528 proceed with what's on the stack, instead of returning zero.
7529 (set_iterator_to_next): If called at the end of a Lisp string,
7530 proceed to consider_string_end without incrementing string
7531 position. Don't increment display vector index past the end of
7532 the display vector. (Bug#11417)
7533 (pos_visible_p): Don't report a position visible when move_it_to
7534 stopped at the last line of window, which happens to be scanned
7535 backwards by the bidi iteration. (Bug#11464)
7537 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7539 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7540 and right-margin display specs even if the spec is invalid or we
7541 are on a TTY, and thus unable to display on the fringes.
7542 That's because the text with the property will not be displayed anyway,
7543 so we need to signal to the caller that this is a "replacing"
7544 display spec. This fixes display when the spec is invalid or we
7547 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7549 * unexaix.c (make_hdr): Fix typo in prototype.
7550 This bug broke the build on AIX. Problem reported by Gilles Pion.
7552 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
7554 * keyboard.c (kbd_buffer_get_event): Read special events also in
7555 batch mode. (Bug#11415)
7557 2012-05-12 Glenn Morris <rgm@gnu.org>
7559 * ns.mk: Update for ns_appbindir no longer having trailing "/".
7561 2012-05-12 Eli Zaretskii <eliz@gnu.org>
7563 * lisp.mk (lisp): Add newcomment.elc.
7565 2012-05-12 Glenn Morris <rgm@gnu.org>
7567 * Makefile.in (MKDIR_P): New, set by configure.
7568 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
7570 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
7572 Remove unused function hourglass_started.
7573 * dispextern.h (hourglass_started):
7574 * w32fns.c (hourglass_started):
7575 * xdisp.c (hourglass_started): Remove.
7577 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7579 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7580 Update dependencies.
7582 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7584 * xgselect.c (xg_select): Put maxfds+1 into a var.
7585 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
7587 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7589 2012-05-10 Dave Abrahams <dave@boostpro.com>
7591 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7592 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7594 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7596 * dbusbind.c (xd_registered_buses): New internal Lisp object.
7597 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7598 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7599 Initialize xd_registered_buses.
7601 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7603 Untag more efficiently if USE_LSB_TAG.
7604 This is based on a proposal by YAMAMOTO Mitsuharu in
7605 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7606 For an admittedly artificial (nth 8000 longlist) benchmark on
7607 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7608 Emacs's overall text size by 1%.
7609 * lisp.h (XUNTAG): New macro.
7610 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7611 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7612 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7613 * eval.c (Fautoload):
7614 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7615 * frame.h (XFRAME): Use XUNTAG.
7617 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7618 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7619 Remove unportable assumptions about print widths of types like
7621 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7622 intptr_t when converting between pointer and integer, to avoid GCC
7623 warnings about wrong width.
7625 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7627 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7628 stack for each reader_thread, instead of defaulting to 8MB
7629 determined by the linker. This avoids failures in creating
7630 subprocesses on Windows 7, see the discussion in this thread:
7631 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7633 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7635 Fix up display of the *Minibuf-0* buffer in the mini window.
7636 * keyboard.c (read_char): Don't clear the echo area if there's no
7638 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7639 contents of *Minibuf-0*) if there's no message displayed in its stead.
7641 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7643 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7646 2012-05-06 Chong Yidong <cyd@gnu.org>
7648 * lisp.mk (lisp): Update.
7650 2012-05-05 Jim Meyering <meyering@redhat.com>
7652 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7654 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7656 * data.c (PUT_ERROR): New macro.
7657 (syms_of_data): Use it. Add new error type `user-error'.
7658 * undo.c (user_error): New function.
7659 (Fprimitive_undo): Use it.
7660 * print.c (print_error_message): Adjust print style for `user-error'.
7661 * keyboard.c (user_error): New function.
7662 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7664 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7666 Do not limit current-time-string to years 1000..9999.
7667 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7668 (Fcurrent_time_string): Support any year that is supported by the
7669 underlying localtime representation. Don't use asctime, as it
7670 has undefined behavior for years outside the range -999..9999.
7672 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7674 Fix race conditions involving setenv, gmtime, localtime, asctime.
7675 Without this fix, interrupts could mess up code that uses these
7676 nonreentrant functions, since setting TZ invalidates existing
7677 tm_zone or tzname values, and since most of these functions return
7678 pointers to static storage.
7679 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7680 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7681 Grow the critical sections to include not just invoking
7682 localtime/gmtime, but also accessing these functions' results
7683 including their tm_zone values if any, and any related TZ setting.
7684 (format_time_string): Last arg is now struct tm *, not struct tm **,
7685 so that the struct tm is saved in the critical section.
7686 All callers changed. Simplify allocation of initial buffer, partly
7687 motivated by the fact that memory allocation needs to be outside
7688 the critical section.
7690 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7692 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7693 with RESET_INTERVAL.
7695 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7696 Remove duplicated buffer name initialization.
7698 2012-05-02 Jim Meyering <jim@meyering.net>
7700 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7702 * xfns.c (x_window): Use xstrdup (Bug#11375).
7704 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7706 * xdisp.c (pos_visible_p): If already at a newline from the
7707 display string before the 'while' loop, don't walk back the glyphs
7708 from it3.glyph_row. Solves assertion violation when the display
7709 string begins with a newline (egg.el). (Bug#11367)
7711 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7713 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7716 2012-05-01 Glenn Morris <rgm@gnu.org>
7718 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7719 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7720 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7721 All were removed before 23.1.
7723 * dispnew.c: Remove HAVE_LIBNCURSES test;
7724 it is always true on relevant platforms.
7726 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7727 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7729 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
7731 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
7733 * .gdbinit (xpr): Remove checks for no longer existing misc types.
7734 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
7737 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
7739 Do not avoid creating empty evaporating overlays (Bug#9642).
7740 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7741 That is, do not delete an evaporating overlay if it becomes
7742 empty after its bounds are adjusted to fit within its buffer.
7743 This fix caused other problems, and I'm reverting it until we get
7744 to the bottom of them.
7746 2012-04-27 Chong Yidong <cyd@gnu.org>
7748 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7750 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7752 * xdisp.c (pos_visible_p): If the window start position is beyond
7753 ZV, start the display from buffer beginning. Prevents assertion
7754 violation in init_iterator when the minibuffer window is scrolled
7757 * window.c (window_scroll_pixel_based): Likewise.
7759 2012-04-27 Chong Yidong <cyd@gnu.org>
7761 * keymap.c (where_is_internal): Doc fix (Bug#10872).
7763 2012-04-27 Glenn Morris <rgm@gnu.org>
7765 * fileio.c (Fcopy_file, Fset_file_selinux_context):
7766 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
7768 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7770 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
7771 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
7773 2012-04-26 Eli Zaretskii <eliz@gnu.org>
7775 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7776 display element, check also the underlying string or buffer
7777 character. (Bug#11341)
7779 * w32menu.c: Include w32heap.h.
7780 (add_menu_item): If the call to AppendMenuW (via
7781 unicode_append_menu) fails, disable Unicode menus only if we are
7782 running on Windows 9X/Me.
7784 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7786 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
7787 (xgetint): Add missing shift for LSB tags.
7789 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7791 * keyboard.c (read_char): Don't wipe echo area for select window
7792 events: These might get delayed via `mouse-autoselect-window'
7795 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
7797 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
7798 manipulation of :loaded-from data.
7800 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
7802 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
7803 now a cons (bug#11311).
7805 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7807 Do not create empty overlays with the evaporate property (Bug#9642).
7808 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7809 if it becomes empty after its bounds are adjusted to fit within
7810 its buffer. Without this fix, in a nonempty buffer (let ((o
7811 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7812 yields an empty overlay that has the evaporate property, which is
7813 not supposed to happen.
7815 Fix minor GTK3 problems found by static checking.
7816 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7817 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7818 (struct _EmacsFixedClass, emacs_fixed_get_type):
7819 Move decls here from emacsgtkfixed.h, since they needn't be public.

7821 (emacs_fixed_class_init): Omit unused local.
7822 (emacs_fixed_child_type): Remove; unused.

7824 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7825 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
7826 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
7827 (EMACS_FIXED_GET_CLASS): Remove; unused.
7828 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
7830 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
7831 Problem reported by Juanma Barranquero for Windows -Wunused-function.
7833 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7835 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
7836 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
7837 (__malloc_size_t, __malloc_ptrdiff_t):
7838 Remove. All uses removed, replaced by the definiens if needed,
7839 since we can assume C89 or better now.
7840 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
7841 (protect_malloc_state, align, get_contiguous_space)
7842 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

7848 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
7849 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
7850 Define using prototypes, not old style.
7851 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
7852 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
7853 (align): Don't assume that signed integer overflow wraps around.
7854 Omit unused local var.
7855 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
7856 (_free_internal_nolock, memalign, mallochook, reallochook):
7857 Omit no-longer-needed casts.
7858 (valloc): Use getpagesize, not __getpagesize.
7859 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
7860 (struct hdr): The 'magic' member is now size_t, not unsigned long.
7862 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
7864 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
7866 Move functions from C to Lisp. Make non-blocking method calls
7867 the default. Implement further D-Bus standard interfaces.
7869 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
7870 (QCdbus_request_name_allow_replacement)
7871 (QCdbus_request_name_replace_existing)

7909 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7911 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
7912 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
7913 Do not assume ptrdiff_t is the same width as 'int'.
7915 * alloc.c: Handle unusual debugging option combinations.
7916 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
7917 since the two debugging options are incompatible.
7918 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7920 (mem_init, mem_insert, mem_insert_fixup):
7921 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

7951 * print.c (print_preprocess): Only check print_depth if print-circle
7953 (print_object): Check for cycles even when print-circle is nil and
7954 print-gensym is t, but only check print_depth if print-circle is nil.
7956 2012-04-20 Chong Yidong <cyd@gnu.org>
7958 * process.c (wait_reading_process_output): If EIO occurs on a pty,
7959 set the status to "failed" and ensure that sentinel is run.

7974 farther than the first row after the header line, if any.
7975 Don't consider the header-line row as "partially visible", even if
7976 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
7978 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

8013 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
8014 New extern decls, to avoid calling undeclared functions.
8015 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
8016 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
8017 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
8018 (NEED_MEM_INSERT): New macro.
8019 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
8020 Remove one incorrect comment and fix another.

8034 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
8035 Remove decls. This fixes an "It stinks!".

8039 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
8041 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

8054 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
8055 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
8056 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
8057 * s/netbsd.h, s/sol2-6.h:
8058 Remove definition of GC_MARK_STACK, since the default now works.
8059 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
8060 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
8061 no longer the default.
8062 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
8064 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
8066 * lread.c (lisp_file_lexically_bound_p):

8087 2012-04-11 Daniel Colascione <dancol@dancol.org>
8089 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
8090 against is gone. It's better to use vfork now so that when Cygwin
8091 gains a new, working vfork, we use it automatically (bug#10398).
8093 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

8111 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
8113 * w32.c (w32_delayed_load): Record the full path of the library
8114 being loaded (bug#10424).
8116 2012-04-09 Glenn Morris <rgm@gnu.org>
8118 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
8119 not just in the obarray, before snarfing them. (Bug#11036)
8121 * Makefile.in ($(leimdir)/leim-list.el):
8122 Pass EMACS rather than BUILT_EMACS.

8131 Add convenience `GNUTLS_LOG2i' macro.
8133 * gnutls.c (gnutls_log_function2i): Convenience log function.
8134 (emacs_gnutls_read): Use new log functions,
8135 `gnutls_handshakes_tried' process member, and

8146 * minibuf.c (Fread_variable): Callers changed.
8148 2012-04-09 Eli Zaretskii <eliz@gnu.org>
8150 * xdisp.c (set_cursor_from_row): If the display string appears in
8151 the buffer at position that is closer to point than the position
8152 after the display string, display the cursor on the first glyph of
8153 the display string. Fixes cursor display when a 'display' text
8154 property immediately follows invisible text. (Bug#11094)
8156 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
8158 composite.c: use 'double' consistently
8159 * composite.c (get_composition_id): Use 'double' consistently
8160 instead of converting 'float' to 'double' and vice versa; this is
8161 easier to understand and avoids a GCC warning.
8163 2012-04-09 Glenn Morris <rgm@gnu.org>
8165 * Makefile.in: Generate leim-list with bootstrap-emacs, in
8166 preparation for dumping it with emacs. (Bug#4789)

8188 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
8189 (mark_memory): Mark Lisp_Objects only if pointers might hide in
8190 objects, as mark_maybe_pointer will catch them otherwise.
8191 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
8192 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
8194 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
8196 Fix typo that broke non-Windows builds.
8197 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

8208 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
8209 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
8210 [!WINDOWSNT]: New macros.
8211 (init_libxml2_functions, libxml2_loaded_p): New functions.
8212 (parse_region): Call fn_xmlCheckVersion instead of using the macro
8213 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
8214 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
8215 Calls xmlCleanupParser only if libxml2 was loaded (or statically
8217 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
8218 Call init_libxml2_functions before calling libxml2 functions.
8219 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
8221 * emacs.c: Don't include libxml/parser.h.
8222 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
8223 xmlCleanupParser directly.
8225 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
8227 2012-04-07 Eli Zaretskii <eliz@gnu.org>
8229 * indent.c (Fvertical_motion): If there is a display string at
8230 point, use it.vpos to compute how many lines to backtrack after
8231 move_it_to point. (Bug#11133)
8233 2012-04-06 Eli Zaretskii <eliz@gnu.org>
8235 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
8236 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
8237 about subtle differences between FETCH_CHAR* and STRING_CHAR*
8238 macros related to unification of CJK characters. For the details,
8239 see the discussion following the message here:
8240 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
8242 2012-04-04 Chong Yidong <cyd@gnu.org>
8244 * keyboard.c (Vdelayed_warnings_list): Doc fix.
8246 2012-04-01 Eli Zaretskii <eliz@gnu.org>
8248 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

8256 2012-03-31 Eli Zaretskii <eliz@gnu.org>
8258 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
8259 position we get to after a call to move_it_to fails the
8260 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
8261 only if we wind up in a string from display property. (Bug#11063)
8263 * window.c (Fdelete_other_windows_internal): Invalidate the row
8264 and column information about mouse highlight, so that redisplay
8265 restores it after reallocating the glyph matrices. (Bug#7464)
8267 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
8268 string comes from a `display' text property, use the buffer
8269 position of that property as if we actually saw that position in
8271 (move_it_by_lines): Remove the assertion that
8272 "it->current_x == 0 && it->hpos == 0" which can be legitimately
8273 violated when there's a before-string at the beginning of a line.
8276 2012-03-30 Eli Zaretskii <eliz@gnu.org>
8278 * xdisp.c (append_space_for_newline): If the default face was
8279 remapped, use the remapped face for the appended newline.
8280 (extend_face_to_end_of_line): Use the remapped default face for
8281 extending the face to the end of the line.
8282 (display_line): Call extend_face_to_end_of_line when the default
8283 face was remapped. (Bug#11068)
8285 2012-03-29 Eli Zaretskii <eliz@gnu.org>
8287 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

8307 handle-select-window too (Bug#8996).
8309 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
8311 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
8313 2012-03-25 Kenichi Handa <handa@m17n.org>
8315 * dispextern.h (struct glyph): Change the bit length of
8316 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
8318 2012-03-24 Eli Zaretskii <eliz@gnu.org>
8320 * s/ms-w32.h (tzname): Include time.h before redirecting to
8321 _tzname. Fixes the MSVC build. (Bug#9960)

8325 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
8328 * xterm.c (XTread_socket): Only modify handling_signal if
8329 !SYNC_INPUT. (Bug#11080)
8331 2012-03-23 Eli Zaretskii <eliz@gnu.org>
8333 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
8334 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
8335 when fetching a multibyte character consumes more bytes than
8336 CHAR_BYTES returns, due to unification of CJK characters in
8337 string_char. (Bug#11073)
8339 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
8341 * process.c (wait_reading_process_output): Handle pty disconnect
8342 by refraining from sending oneself a SIGCHLD (bug#10933).

8353 2012-03-21 Chong Yidong <cyd@gnu.org>
8355 * xfaces.c (Vface_remapping_alist): Doc fix.
8357 2012-03-20 Eli Zaretskii <eliz@gnu.org>
8359 * w32proc.c (Fw32_set_console_codepage)
8360 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

8365 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
8366 to reflect default non-nil value of redisplay-dont-pause.

8371 it fit in a valid range (Bug#11003).
8373 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8375 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8376 that is not from display property, accept the row as a "cursor
8377 row" if one of the string's character has a non-nil `cursor'
8378 property. Fixes cursor positioning when there are newlines in
8379 overlay strings, e.g. in icomplete.el. (Bug#11035)
8381 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
8383 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
8385 2012-03-12 Chong Yidong <cyd@gnu.org>
8387 * eval.c (inhibit_lisp_code): Rename from
8388 inhibit_window_configuration_change_hook; move from window.c.
8390 * xfns.c (unwind_create_frame_1, Fx_create_frame):
8391 * window.c (run_window_configuration_change_hook)
8392 (syms_of_window): Callers changed.
8394 2012-03-11 Chong Yidong <cyd@gnu.org>
8396 * keymap.c (Fkey_description): Doc fix (Bug#9700).

8412 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8415 2012-03-03 Glenn Morris <rgm@gnu.org>

8430 * buffer.c (buffer-list-update-hook): Doc fix.
8432 2012-02-29 Eli Zaretskii <eliz@gnu.org>

8435 push_it before setting up the iterator for the first overlay
8436 string, even if we have an empty string loaded.
8437 (next_overlay_string): If there's an empty string on the iterator
8438 stack, pop the stack. (Bug#10903)
8440 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8442 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8443 Suggested by Stefan Monnier in
8444 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8445 * alloc.c (widen_to_Lisp_Object): New static function.
8446 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8447 and widening them to Lisp_Objects. This would work even if
8448 USE_LSB_TAG is defined and wide integers are used, which might
8449 happen in a future version of Emacs.
8451 2012-02-25 Chong Yidong <cyd@gnu.org>
8453 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

8468 call when setting menu-bar-lines and tool-bar-lines parameters.
8469 (unwind_create_frame_1): New helper function.
8471 * window.c (inhibit_window_configuration_change_hook): New var.
8472 (run_window_configuration_change_hook): Obey it.
8473 (syms_of_window): Initialize it.
8475 2012-02-22 Chong Yidong <cyd@gnu.org>

8490 when computing $valmask.
8492 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8493 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8494 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8495 It's useless in that case, and it can cause problems on hosts
8496 that allocate halves of EMACS_INT values separately.
8497 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8498 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8499 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8500 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8501 it avoids undefined behavior on hosts where shifting right by more
8502 than the word width has undefined behavior.
8504 2012-02-19 Chong Yidong <cyd@gnu.org>
8506 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
8507 (Funhandled_file_name_directory, Ffile_name_as_directory)

8526 2012-02-15 Chong Yidong <cyd@gnu.org>
8528 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

8547 as that creates a dangerous corner case.
8549 * window.c (Fdelete_window_internal): Invalidate the mouse
8550 highlight (Bug#9904).
8552 2012-02-12 Glenn Morris <rgm@gnu.org>

8582 2012-02-07 Chong Yidong <cyd@gnu.org>
8584 * buffer.c (Fbuffer_local_variables)
8585 (buffer_lisp_local_variables): Handle unbound vars correctly;
8586 don't let Qunbound leak into Lisp.
8588 2012-02-07 Glenn Morris <rgm@gnu.org>
8590 * image.c (Fimagemagick_types): Doc fix.
8592 * image.c (imagemagick-render-type): Change it from a lisp object

8625 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
8627 Handle overflow when computing char display width (Bug#9496).
8628 * character.c (char_width): Return EMACS_INT, not int.
8629 (char_width, c_string_width): Check for overflow when
8630 computing the width; this is possible now that individual
8631 characters can have unbounded width. Problem introduced
8632 by merge from Emacs 23 on 2012-01-19.
8634 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

8774 (Fmake_directory_internal): Use it.

9304 behave as if the cursor position were at the window margin.
9306 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
9307 and the cursor position is out of bounds, behave as if the cursor

9338 * dispnew.c (verify_row_hash): Call row_hash for computing the
9339 hash code of a row, instead of duplicating code from xdisp.c.
9341 * dispextern.h (row_hash): Add prototype.
9343 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
9345 * frame.c (delete_frame): Don't delete the terminal when the last

9377 * image.c (imagemagick_load_image): Fix typo.
9379 2011-11-14 Eli Zaretskii <eliz@gnu.org>
9381 * xdisp.c (display_line): Move the call to

9448 Avoid some portability problems by eschewing 'extern inline' functions.
9449 The trivial performance wins aren't worth the portability hassles; see
9450 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
9452 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

9500 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
9501 This is also needed for porting to any host where GC_MARK_STACK is
9502 not GC_MAKE_GCPROS_NOOPS.
9503 (which_symbols): Use it.
9505 2011-11-07 Kenichi Handa <handa@m17n.org>

9527 (window_box_right, window_box_right_offset): Declare extern.
9528 Otherwise, these inline functions do not conform to C99 and
9529 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
9530 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
9531 * intervals.c (adjust_intervals_for_insertion)
9532 (adjust_intervals_for_deletion): Now extern, because otherwise the
9533 extern inline functions 'offset_intervals' couldn't refer to it.
9534 (static_offset_intervals): Remove.
9535 (offset_intervals): Rewrite using the old contents of
9536 static_offset_intervals. The old version didn't conform to C99
9537 because an extern inline function contained a reference to an
9538 identifier with static linkage.

9851 * editfns.c: Rewrite current-time-zone so that it invokes
9852 the equivalent of (format-time-string "%Z") to get the time zone name.
9853 This fixes a bug when the time zone name contains characters that
9854 need converting from the system time locale to Emacs internal format.
9855 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9856 that patch fixed format-time-string to do the conversion, but
9857 I forgot to fix current-time-zone.
9858 (format_time_string): New function, containing most of
9859 what Fformat_time_string used to contain.
9860 (Fformat_time_string): Rewrite in terms of format_time_string.
9861 This doesn't change this function's behavior.
9862 (current-time-zone): Rewrite to use format_time_string.
9863 This fixes the bug reported by Michael Schierl in
9864 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9865 Jason Rumney's 2007-06-07 change worked around this bug, but
9867 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9869 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9871 * xdisp.c (start_display): If the character at POS is displayed
9872 via a display vector, reset IT->current.dpvec_index to zero.
9873 (try_window_reusing_current_matrix): If a line ends in a display
9874 vector or the next line starts in a display vector, continue
9875 redrawing the window even though the character position of
9876 start_row was reached.
9879 2011-10-18 Chong Yidong <cyd@gnu.org>
9881 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9882 with nobreak-char-display too.
9884 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9886 Fix part 3 of bug#9771.
9887 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9888 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9889 non-neutral characters if the current character is a paragraph
9890 separator (a.k.a. Newline). This avoids running the same
9891 expensive loop twice, once when we consume the preceding newline
9892 and the other time when the line actually needs to be displayed.
9893 Avoid the loop when we see neutrals on the base embedding level
9894 following a character whose directionality is the same as the
9895 paragraph's. This avoids running the expensive loop when a line
9896 ends in a long sequence of neutrals, like control characters.
9897 Add assertion against STRONG_AL type. Slightly rearrange code
9898 that determines the type of a neutral given the first non-neutral
9900 (bidi_level_of_next_char): Set next_en_pos to zero when
9901 invalidating its info.
9903 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9905 * xdisp.c (push_display_prop): Determine whether to record string
9906 or buffer position by IT->string, not by IT->method. Allow
9907 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9908 (move_it_vertically_backward): Don't look for character position
9909 immediately after the newline when in a continuation line.
9912 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9914 * window.c (coordinates_in_window): Rewrite and delabelize
9915 vertical border check. (Bug#5357) (Bug#9618)
9917 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9919 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9920 errors in XSetWindowBorder (bug#9310).
9922 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9924 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9925 avoid crash when xmalloc overrun checking is enabled.
9927 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9929 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9930 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9931 cursor motion with <left> and <right> arrow keys.
9933 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9934 some callers set that themselves.
9936 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9938 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9939 display string and the previous row comes from the same string and
9940 is empty. (Bug#9739) (Bug#9738)
9942 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9944 * doc.c (get_doc_string): Encode file name (bug#9735).
9946 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9948 * bidi.c (bidi_level_of_next_char):
9949 * xdisp.c (get_visually_first_element): Remove old incorrect
9950 comments regarding the Unicode Line Separator character.
9952 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9954 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9956 * alloc.c (Fgc_status): Do not access beyond zombies array
9957 boundary if nzombies > MAX_ZOMBIES.
9958 * alloc.c (dump_zombies): Add missing format specifier.
9960 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9962 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9963 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9965 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9966 Some packages use them to denote characters with modifiers.
9968 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9970 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9971 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9972 matching a pp-number. Rename parameter var to var1.
9974 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9976 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9978 2011-10-08 Glenn Morris <rgm@gnu.org>
9980 * callint.c (Fcall_interactively): Give a more explicit error for the
9981 'c' case with a non-character input. (Bug#8479)
9983 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9985 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9987 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9988 lines that are hscrolled on the left.
9990 * dispnew.c (buffer_posn_from_coords): Account for a possible
9991 presence of header-line. (Bug#4426)
9993 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
9995 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
9996 Don't advertise functionality which we discourage or doesn't work.
9998 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
10000 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
10001 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
10002 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
10003 this makes Emacs dump core during garbage collection on rare
10004 occasions. sizeof is obviously inferior to offsetof here, so
10005 stick with offsetof.
10006 (GC_POINTER_ALIGNMENT): New macro.
10007 (mark_memory): Omit 3rd (offset) arg; caller changed.
10008 Don't assume EMACS_INT alignment is the same as pointer alignment.
10010 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
10012 * keyboard.c (read_key_sequence_remapped): New var.
10013 (read_key_sequence): Compute remapping in the right buffer.
10014 (command_loop_1): Use read_key_sequence's remapping directly.
10016 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
10018 * dired.c (file_name_completion): Don't expand file name.
10019 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
10020 before checking file name handler.
10022 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
10023 they've been requested explicitly (bug#9591).
10025 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
10027 * keymap.c (Fsingle_key_description): Use make_specified_string
10028 instead of build_string to build string from push_key_description.
10031 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10033 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
10034 This fixes a Y2038 bug on 64-bit hosts.
10035 * buffer.c (reset_buffer):
10036 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
10037 (Fclear_buffer_auto_save_failure):
10038 Use 0, not -1, to represent an unset failure time, since time_t
10039 might not be signed.
10041 Remove dependency on glibc malloc internals.
10042 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10043 Move back here from lisp.h, but with their new implementations.
10044 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10045 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
10046 * charset.c (charset_table_init): New static var.
10047 (syms_of_charset): Use it instead of xmalloc. This removes a
10048 dependency on glibc malloc internals. See Eli Zaretskii's comment in
10049 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
10050 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10051 Move back to alloc.c.
10052 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10053 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
10055 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
10057 * nsterm.m (windowDidResize): Call x_set_window_size only when
10058 ns_in_resize is true. Otherwise set pixelwidth/height and
10059 call change_frame_size (Bug#9628).
10061 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10063 Port --enable-checking=all to Fedora 14 x86-64.
10064 * charset.c (syms_of_charset): Also account for glibc malloc's
10065 internal overhead when calculating the initial malloc maximum.
10067 Port --enable-checking=all to Fedora 14 x86.
10068 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10070 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
10071 (overrun_check_realloc, overrun_check_free):
10072 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
10073 That way, xmalloc returns a properly-aligned pointer even if
10074 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
10075 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
10076 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
10077 into account when calculating the initial malloc maximum.
10078 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10079 Move here from alloc.c, so that charset.c can use it too.
10080 Properly align; the old code wasn't right for common 32-bit hosts
10081 when configured with --enable-checking=all.
10082 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10083 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
10085 2011-09-29 Eli Zaretskii <eliz@gnu.org>
10087 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
10090 2011-09-28 Eli Zaretskii <eliz@gnu.org>
10092 * xdisp.c (compute_display_string_end): If there's no display
10093 string at CHARPOS, return -1.
10095 * bidi.c (bidi_fetch_char): When compute_display_string_end
10096 returns a negative value, treat the character as a normal
10097 character not covered by a display string. (Bug#9624)
10099 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
10101 * lread.c (Fread_from_string): Fix typo in docstring.
10103 2011-09-27 Eli Zaretskii <eliz@gnu.org>
10105 * xdisp.c (handle_invisible_prop): If invisible text ends on a
10106 newline, reseat the iterator instead of bidi-iterating there one
10107 character at a time. (Bug#9610)
10108 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
10109 TO_CHARPOS if the bidi iterator is at base embedding level.
10111 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
10113 * lread.c (readevalloop): Use correct code for NBSP.
10114 (read1): Likewise. (Bug#9608)
10116 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
10118 * dbusbind.c (Fdbus_register_signal): When service is not
10119 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
10121 2011-09-25 Glenn Morris <rgm@gnu.org>
10123 * buffer.c (truncate-lines): Doc fix.
10125 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
10127 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
10128 (Fset_window_next_buffers): Doc fix.
10130 2011-09-24 Glenn Morris <rgm@gnu.org>
10132 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
10134 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
10136 Fix minor problems found by static checking.
10137 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
10138 * indent.c (Fvertical_motion): Fix == vs = typo.
10140 2011-09-24 Eli Zaretskii <eliz@gnu.org>
10142 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
10143 Default value is now t. Doc fix.
10145 * indent.c (Fvertical_motion): Compute and apply the overshoot
10146 logic when moving up, not only when moving down. Fix the
10147 confusing name and values of the it_overshoot_expected variable;
10148 logic changes accordingly. (Bug#9254) (Bug#9549)
10150 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
10151 CHARPOS is covered by a display string which includes newlines.
10152 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
10153 is covered by a display string with embedded newlines.
10155 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
10157 * dbusbind.c (Fdbus_register_signal): Add match rule to
10158 Vdbus_registered_objects_table. (Bug#9581)
10159 (Fdbus_register_method, Vdbus_registered_objects_table):
10162 2011-09-24 Jim Meyering <meyering@redhat.com>
10164 do not ignore write error for any output size
10165 The previous change was incomplete.
10166 While it makes emacs --batch detect the vast majority of stdout
10167 write failures, errors were still ignored whenever the output size is
10168 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
10169 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
10170 && echo FAIL: ignored write error
10171 FAIL: ignored write error
10172 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
10173 && echo FAIL: ignored write error
10174 FAIL: ignored write error
10175 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
10177 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
10179 * emacs.c (Fkill_emacs): In noninteractive mode exit
10180 non-successfully if a write error occurred on stdout. (Bug#9574)
10182 2011-09-21 Eli Zaretskii <eliz@gnu.org>
10184 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
10187 * dispextern.h (struct it): Update the comment documenting what
10190 2011-09-20 Eli Zaretskii <eliz@gnu.org>
10192 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
10193 a display string, extend search for cursor position to end of row.
10194 (find_row_edges): If the row ends in a newline from a display
10195 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
10196 Handle the case of a display string with multiple newlines.
10197 (Fcurrent_bidi_paragraph_direction): Fix search for previous
10198 non-empty line. Fixes confusing cursor motion with arrow keys at
10199 the beginning of a line that starts with whitespace.
10201 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10203 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
10206 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
10208 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
10209 boolean (Bug#9154).
10211 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10213 * xdisp.c (display_line): Record maximum and minimum buffer
10214 positions even if no glyphs were produced (e.g., by a zero-width
10215 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
10216 buffer positions that will be removed from the glyph row because
10218 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
10219 column is beyond frame width: don't subtract 1 "pixel" when
10220 computing width of the stretch.
10221 (reseat_at_next_visible_line_start): Undo the change made on
10222 2011-09-17 that saved paragraph information and restored it after
10223 the call to `reseat'. (Bug#9545)
10225 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10227 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
10228 and turn window cursor on if cleared (Bug#9415).
10230 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
10232 * search.c (boyer_moore): Take unibyte characters from pattern
10233 literally. (Bug#9458)
10235 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10237 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
10239 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
10241 Fix minor problem found by static checking.
10242 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
10243 initialized, to pacify gcc -Wuninitialized.
10245 * fileio.c: Report proper errno when syscall falls.
10246 (Finsert_file_contents): Save and restore errno,
10247 so that report_file_error outputs the correct diagnostic.
10248 (Fwrite_region) [CLASH_DETECTION]: Likewise.
10250 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10252 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
10254 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10256 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
10257 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
10259 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10261 * xdisp.c (reseat_at_next_visible_line_start): Keep information
10262 about the current paragraph and restore it after the call to reseat.
10264 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
10265 (bidi_find_paragraph_start): Search back for paragraph beginning
10266 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
10267 (bidi_move_to_visually_next): Only trigger paragraph-related
10268 computations when the last character is a newline or at EOB, not
10269 just any NEUTRAL_B. (Bug#9470)
10271 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
10272 truncated lines if point is covered by a display string. (Bug#9524)
10274 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
10276 * xselect.c: Relax test for outgoing X longs (Bug#9498).
10277 (cons_to_x_long): New function.
10278 (lisp_data_to_selection_data): Use it. Correct the test for
10279 short-versus-long data; it was negated. Break out of vector
10280 loop, for efficiency, when a long datum is discovered.
10282 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
10284 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
10286 2011-09-16 Eli Zaretskii <eliz@gnu.org>
10288 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
10289 GCC PR/17406) by declaring this function with external scope.
10291 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10293 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
10294 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
10296 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
10298 * editfns.c (Fformat): Correctly handle text properties on "%%".
10300 2011-09-15 Eli Zaretskii <eliz@gnu.org>
10302 * xterm.c (x_draw_composite_glyph_string_foreground):
10303 * w32term.c (x_draw_composite_glyph_string_foreground):
10304 * term.c (encode_terminal_code):
10305 * composite.c (composition_update_it, get_composition_id):
10306 * xdisp.c (get_next_display_element)
10307 (fill_composite_glyph_string): Add comments about special meaning
10308 of TAB characters in a composition.
10310 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10312 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
10313 This occurs when processing a multibyte format.
10314 Problem reported by Wolfgang Jenker.

10318 * xdisp.c (try_cursor_movement): Only check for exact match if
10319 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
10321 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10323 Remove unused external symbols.
10324 * dispextern.h (calc_pixel_width_or_height): Remove decl.
10325 * xdisp.c (calc_pixel_width_or_height): Now static.
10326 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
10327 * indent.c (check_display_width):
10328 * w32term.c: Fix comment to match code.
10329 * xterm.c, xterm.h (x_catching_errors): Remove.
10331 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10333 * xselect.c: Use signed conversions more consistently (Bug#9498).
10334 (selection_data_to_lisp_data): Assume incoming selection data are
10335 signed integers, not unsigned. This is to be consistent with
10336 outgoing selection data, which was modified to use signed integers
10337 in as part of the fix to Bug#9196 in response to Jan D.'s comment
10338 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
10339 expects long, not unsigned long.
10341 2011-09-14 Eli Zaretskii <eliz@gnu.org>
10343 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
10344 computation of loop end. Reported by Johan Bockgård
10347 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
10349 * frame.c (Fother_visible_frames_p): Function deleted.
10351 2011-09-12 Eli Zaretskii <eliz@gnu.org>
10353 * indent.c (compute_motion): Process display vector front to back
10354 rather than the other way around. (Bug#2496)
10356 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
10358 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
10360 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
10362 * minibuf.c (Fread_from_minibuffer): Doc fix.
10364 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10366 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
10367 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
10369 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
10371 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
10372 value for non-existent files.
10374 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10376 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10377 set its "size" to -1. This will set the modtime_size field of
10378 the corresponding buffer to -1, which is what
10379 verify-visited-file-modtime expects for files that do not exist.
10382 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
10384 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10386 * lisp.h: ... from here. push_key_description is no longer
10387 defined in keyboard.c, so its declaration should not be in
10388 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10389 logically belongs with push_key_description.
10391 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10393 * buffer.h: Include <sys/types.h> instead of <time.h>.
10394 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
10395 Problem reported by Herbert J. Skuhra.
10397 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
10399 * xml.c (parse_region): Make the parsing work for
10400 non-comment-starting XML files again (bug#9144).
10402 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
10404 * image.c (gif_load): Fix calculation of bottom and right corner.
10407 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10409 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10410 redisplay in small windows.
10412 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10414 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10416 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10418 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10419 Operate on live windows only.
10421 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10423 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10425 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10427 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10428 only under bidi iteration.
10430 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10432 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10434 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10436 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10437 Without this fix, the command to link temacs failed due to an
10438 undefined symbol __builtin_isnan. This is because
10439 /usr/include/iso/math_c99.h #defines isnan(x) to
10440 __builtin_isnan(x), but the bundled gcc, which identifies itself
10441 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10443 * floatfns.c (isnan): #undef, and then #define to a clone of
10445 (Fisnan): Always define, since it's always available now.
10446 (syms_of_floatfns): Always define isnan at the Lisp level.
10448 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10450 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10452 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10454 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10455 The previous code assumed that file offsets (off_t values) fit in
10456 EMACS_INT variables, which is not true on typical 32-bit hosts.
10457 The code messed up by falsely reporting buffer overflow in cases
10458 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10459 when "big" contains more than 2**29 bytes, even though this
10460 inserts just one byte and does not overflow the buffer.
10461 (Finsert_file_contents): Store file offsets as off_t
10462 values, not as EMACS_INT values. Check for overflow when
10463 converting between EMACS_INT and off_t. When checking for
10464 buffer overflow or for overlap, take the offsets into account.
10465 Don't use EMACS_INT for small values where int suffices.
10466 When checking for overlap, fix a typo: ZV was used where
10467 ZV_BYTE was intended.
10468 (Fwrite_region): Don't assume off_t fits into 'long'.
10469 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10471 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10473 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10475 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10477 sprintf-related integer and memory overflow issues (Bug#9412).
10479 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10480 (esprintf, exprintf, evxprintf): New functions.
10481 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10482 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10483 (modify_event_symbol): Do not assume that the length of
10484 name_alist_or_stem is safe to alloca and fits in int.
10485 (Fexecute_extended_command): Likewise for function name and binding.
10486 (Frecursion_depth): Wrap around reliably on integer overflow.
10487 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10488 since some callers pass EMACS_INT values.
10489 (Fsingle_key_description): Don't crash if symbol name contains more
10490 than MAX_ALLOCA bytes.
10491 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10492 (get_minibuffer): Arg is now EMACS_INT, not int.
10493 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10494 (esprintf, exprintf, evxprintf): New decls.
10495 * window.h (command_loop_level, minibuf_level): Reflect API changes.
10497 * dbusbind.c (signature_cat): New function.
10498 (xd_signature, Fdbus_register_signal):
10499 Do not overrun buffer; instead, report string overflow.
10501 * dispnew.c (add_window_display_history): Don't overrun buffer.
10502 Truncate instead; this is OK since it's just a log.
10504 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10505 even if the time zone offset is outlandishly large.
10506 Don't mishandle offset == INT_MIN.
10508 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10509 when creating daemon; the previous buffer-overflow check was incorrect.
10511 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10512 which has the guts of the old verror function.
10514 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10515 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10517 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10518 (font_unparse_xlfd): Don't blindly alloca long strings.
10519 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10520 fits in int, when using sprintf. Use single snprintf to count
10521 length of string rather than counting it via multiple sprintfs;
10522 that's simpler and more reliable.
10523 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10524 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10525 sprintf, in case result does not fit in int.
10527 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10528 (fontset_from_font): Print it.
10530 * frame.c (tty_frame_count): Now printmax_t, not int.
10531 (make_terminal_frame, set_term_frame_name): Print it.
10532 (x_report_frame_params): In X, window IDs are unsigned long,
10533 not signed long, so print them as unsigned.
10534 (validate_x_resource_name): Check for implausibly long names,
10535 and don't assume name length fits in 'int'.
10536 (x_get_resource_string): Don't blindly alloca invocation name;
10537 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10540 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10541 (xg_check_special_colors, xg_set_geometry):
10542 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10544 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10545 Use esprintf, not sprintf, in case result does not fit in int.
10547 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10548 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10549 it as a large positive number.
10550 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10551 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10553 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10554 in case result does not fit in int.
10556 * print.c (float_to_string): Detect width overflow more reliably.
10557 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10558 buffer overrun. Don't assume list length fits in 'int'. Treat
10559 print length of 0 as 0, not as infinity; to be consistent with other
10560 uses of print length in this function. Don't overflow print length
10561 index. Don't assume hash table size fits in 'long', or that
10562 vectorlike size fits in 'unsigned long'.
10564 * process.c (make_process): Use printmax_t, not int, to format
10565 process-name gensyms.
10567 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10569 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10570 to avoid potential buffer overrun.
10572 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10573 if X resource line is longer than 512 bytes.
10575 * xfns.c (x_window): Make sprintf buffer a bit bigger
10576 to avoid potential buffer overrun.
10578 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10580 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10582 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10584 Integer overflow fixes for scrolling, etc.
10585 Without these, Emacs silently mishandles large integers sometimes.
10586 For example, "C-u 4294967297 M-x recenter" was treated as if
10587 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10589 * xdisp.c (try_window_id): Check Emacs fixnum range before
10590 converting to 'int'.
10592 * window.c (window_scroll_line_based, Frecenter):
10593 Check that an Emacs fixnum is in range before assigning it to 'int'.
10594 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10595 values converted from Emacs fixnums.
10596 (Frecenter): Don't wrap around a line count if it is out of 'int'
10597 range; instead, treat it as an extreme value.
10598 (Fset_window_configuration, compare_window_configurations):
10599 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10601 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10602 that can exceed INT_MAX. Check that EMACS_INT value is in range
10603 before assigning it to the (possibly-narrower) index.
10604 (match_limit): Don't assume that a fixnum can fit in 'int'.
10606 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10609 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10610 (Fvertical_motion): Don't wrap around LINES values that don't fit
10611 in 'int'. Instead, treat them as extreme values. This is good
10612 enough for windows, which can't have more than INT_MAX lines anyway.
10614 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10616 * Require libxml/parser.h to avoid compilation warning.
10618 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10620 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10621 since this reportedly can destroy thread storage.
10623 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10625 * syntax.c (find_defun_start): Update all cache variables if
10626 exiting early (Bug#9401).
10628 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10630 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10632 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10633 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10634 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10636 * term.c (tty_append_glyph): New function.
10637 (produce_stretch_glyph): Static function and its prototype deleted.
10639 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10642 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10644 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10645 when checking :margin (Bug#9390).
10646 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10647 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10648 so that the name doesn't mislead. All uses changed.
10650 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10652 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
10655 2011-08-27 Eli Zaretskii <eliz@gnu.org>
10657 * xdisp.c (move_it_to): Don't bail out early when reaching
10658 position beyond to_charpos, if we are scanning backwards.
10659 (move_it_vertically_backward): When DY == 0, make sure we get to
10660 the first character in the line after the newline.
10662 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10664 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10665 (ccl_driver): Do not generate an out-of-range pointer.
10666 (Fccl_execute_on_string): Remove unnecessary check for
10667 integer overflow, noted by Stefan Monnier in
10668 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10669 Remove a FIXME that didn't need fixing.
10670 Simplify the newly-introduced buffer reallocation code.
10672 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10674 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10676 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10678 Integer and memory overflow issues (Bug#9196).
10680 * doc.c (get_doc_string): Rework so that
10681 get_doc_string_buffer_size is the actual buffer size, rather than
10682 being 1 less than the actual buffer size; this makes xpalloc more
10685 * image.c (x_allocate_bitmap_record, cache_image):
10686 * xselect.c (Fx_register_dnd_atom):
10687 Simplify previous changes by using xpalloc.
10689 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10690 since either will do and ptrdiff_t is convenient with xpalloc.
10692 * charset.c (charset_table_size)
10693 (struct charset_sort_data.priority): Now ptrdiff_t.
10694 (charset_compare): Don't overflow if priorities differ greatly.
10695 (Fsort_charsets): Don't assume list length fits in int.
10696 Check for size-calculation overflow when allocating sort data.
10697 (syms_of_charset): Allocate an initial charset table that is
10698 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10700 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10702 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10703 The actual value is always <= INT_MAX, and leaving it unsigned made
10704 overflow checking harder.
10706 * dispextern.h (struct glyph_matrix.rows_allocated)
10707 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10708 with xpalloc. The values are still always <= INT_MAX.
10710 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10712 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10713 (SAFE_NALLOCA): New macro.
10715 * region-cache.c (struct boundary.pos, find_cache_boundary)
10716 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10717 (set_cache_region, invalidate_region_cache)
10718 (revalidate_region_cache, know_region_cache, region_cache_forward)
10719 (region_cache_backward, pp_cache):
10720 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10721 so that ptrdiff_t * can be passed to xpalloc.
10722 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
10723 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
10724 (pp_cache): Don't assume cache_len fits in int.
10725 * region-cache.h: Adjust extern decls to match.
10727 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
10728 EMACS_INT, since either will do, for xpalloc.
10730 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
10731 (xnmalloc, xnrealloc, xpalloc): New functions.
10733 * bidi.c (bidi_shelve_header_size): New constant.
10734 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
10735 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
10737 * bidi.c (bidi_cache_shrink):
10738 * buffer.c (overlays_at, overlays_in, record_overlay_string)
10740 Don't update size of array until after memory allocation succeeds,
10741 because xmalloc/xrealloc may not return.
10742 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10743 now that we have proper integer overflow checking.
10744 (record_overlay_string, overlay_strings): Catch overflows when
10745 calculating size of overlay_str_buf.
10747 * callproc.c (Fcall_process): Check for size overflow when
10748 calculating size of args2.
10749 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
10750 Normally we prefer signed values, but sticking with ptrdiff_t would
10751 require adding more-complicated checks.
10753 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10754 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
10755 Redo buffer-overflow calculations to avoid integer overflow.
10756 Add a FIXME comment where memory seems to be over-allocated.
10758 * character.c (Fstring): Check for size-calculation overflow.
10760 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
10761 unnecessary integer overflow. Check for size overflow.
10762 (encode_coding_object): Don't update size until xmalloc succeeds.
10764 * composite.c (get_composition_id): Check for overflow in glyph
10765 length calculations.
10767 Integer and memory overflow fixes for display code.
10768 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
10769 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
10770 (scrolling_window): Check for overflow in size calculations.
10771 (line_draw_cost, realloc_glyph_pool, add_row_entry):
10772 Don't assume glyph table len fits in int.
10773 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)

10794 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10796 * emacs.c (main): Do not reallocate argv, since there is a null at
10797 the end that can be overwritten, and this way there's no need to
10798 worry about size-calculation overflow.
10799 (sort_args): Check for size-calculation overflow.

10916 (Fx_change_window_property): Use ptrdiff_t, not int, to count
10917 sizes, since they can exceed INT_MAX in size. Check for size

10928 (X_LONG_MIN): New macros.
10929 Use them to make the following changes clearer.
10930 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

10932 future maintainers not to raise the value too much later.
10933 (SELECTION_QUANTUM): Remove, replacing with ...
10934 (selection_quantum): ... new function, which avoids overflow.
10936 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10937 assumption that selection length fits in 'int'.

10954 Don't store size until memory allocation succeeds.
10955 (x_get_window_property): Plug memory leak on memory exhaustion.
10956 Don't double-block input; malloc is safe here. Don't assume 2**34
10957 - 4 fits in unsigned long. Add an xassert to check
10958 XGetWindowProperty overflow. Be more careful about overflow
10959 calculations, and distinguish size from memory overflow better.
10960 (receive_incremental_selection): When tracing, don't assume
10961 unsigned int is less than INT_MAX.
10962 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

10966 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10967 result parameters unless successful. Rely on cons_to_unsigned
10968 to report problems with elements; the old code wasn't right anyway.
10969 (x_check_property_data): Check for int overflow; we cannot use
10970 a wider type due to X limits.

11003 * lisp.h (hash_lookup, hash_put):
11004 * minibuf.c (Ftest_completion):
11005 Use ptrdiff_t for hash table indexes, not int (which is too
11006 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
11007 32-bit --with-wide-int hosts).
11009 * charset.c (Fdefine_charset_internal): Check for integer overflow.
11010 Add a FIXME comment about memory leaks.

11039 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
11040 (x_send_scroll_bar_event): Likewise. Check that the size does not
11041 exceed limits imposed by XClientMessageEvent, as well as the usual
11042 ptrdiff_t and size_t limits.
11044 * keyboard.c: Overflow, signedness and related fixes.
11045 (make_lispy_movement): Use same integer type in forward decl
11046 that is used in the definition.
11047 (read_key_sequence, keyremap_step):
11048 Change bufsize argument back to int, undoing my 2011-03-30 change.
11049 We prefer signed types, and int is wide enough here.
11050 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
11051 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
11052 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
11053 length, not size_t. Use ptrdiff_t for index, not int.
11054 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
11055 possibility of integer overflow.

11083 Prefer int to unsigned where either will do.
11084 (tiff_handler): New function, combining the cores of the
11085 old tiff_error_handler and tiff_warning_handler.

11087 stack buffer overflows. It uses only the features of vsnprintf
11088 that are common to both POSIX and native Microsoft.
11089 (tiff_error_handler, tiff_warning_handler): Use it.
11090 (tiff_load, gif_load, imagemagick_load_image):
11091 Don't assume :index value fits in 'int'.
11092 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

11094 the integer types that MagickCropImage accepts. Don't assume
11095 Vimagemagick_render_type has a nonnegative value. Don't assume

11134 buffers, return left-to-right.
11135 (set_cursor_from_row): Consider candidate row a win if its glyph

11137 positioning on the newline at EOL of R2L text within L2R
11138 paragraph, and vice versa.
11139 (try_cursor_movement): Check continued rows, in addition to
11140 continuation rows. Fixes unwarranted scroll when point enters a
11141 continued line of R2L text within an L2R paragraph, or vice versa.
11142 (cursor_row_p): Consider the case of point being equal to
11143 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
11144 from the end of a short line to the beginning of a continued line
11145 of R2L text within L2R paragraph.

11172 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
11173 instead of CHAR_TO_BYTE. Fixes a crash when a completion
11174 candidate is selected by the mouse, and that candidate has a
11175 composed character under the mouse.
11177 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
11178 coordinates reported by pos-visible-in-window-p for a composed

11188 consider it a hit if to_charpos is anywhere in the range of the
11189 composed buffer positions.
11191 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
11193 * image.c (gif_load): Don't assume that each subimage has the same
11194 dimensions as the base image. Handle disposal method that is
11195 "undefined" by the gif spec (Bug#9335).
11197 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
11199 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

11205 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
11206 from an Org mode buffer to a Speedbar frame.
11208 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
11209 a composition, take its buffer position from IT->cmp_it.charpos.
11210 Fixes cursor positioning at the beginning of a line that begins
11211 with a composed character.
11213 2011-08-18 Eli Zaretskii <eliz@gnu.org>
11215 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
11216 character bidirectional type, use STRONG_L instead. Fixes crashes
11217 in a buffer produced by `describe-categories'.
11219 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
11220 members before the level stack, so they would be saved and
11221 restored when copying iterator state. Fixes incorrect reordering
11222 around TABs covered by display properties.
11224 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
11226 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
11228 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
11230 * eval.c (internal_condition_case, internal_condition_case_1)
11231 (internal_condition_case_2, internal_condition_case_n):
11232 Remove unnecessary aborts (Bug#9081).
11234 2011-08-17 Eli Zaretskii <eliz@gnu.org>
11236 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
11237 has no `load' handler, try opening the file locally. (Bug#9311)
11239 2011-08-16 Ken Brown <kbrown@cornell.edu>
11241 * gmalloc.c: Expand comment.
11243 2011-08-16 Eli Zaretskii <eliz@gnu.org>
11245 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
11246 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
11248 2011-08-16 Ken Brown <kbrown@cornell.edu>
11250 Fix memory allocation problems in Cygwin build (Bug#9273).

11257 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
11259 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
11260 in the static heap.
11261 [CYGWIN] (special_realloc): New function.
11262 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
11263 requests to realloc storage in the static heap.

11274 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
11276 * dispextern.h: Fix a typo in the comment to bidi_type_t.
11278 * chartab.c: Improve commentary for the uniprop_table API.
11280 * bidi.c (bidi_paragraph_init): Support zero value of
11281 bidi_ignore_explicit_marks_for_paragraph_level.
11282 (bidi_initialize): Use uniprop_table instead of including
11283 biditype.h and bidimirror.h.
11285 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
11286 coordinates of the iterator when restoring from ppos_it.
11289 2011-08-14 Kenichi Handa <handa@m17n.org>
11291 * process.c (create_process): Call setup_process_coding_systems
11292 after the pid of the process is set to -1 (Bug#8162).
11294 2011-08-14 Eli Zaretskii <eliz@gnu.org>
11296 * xdisp.c (move_it_in_display_line_to): Don't invoke
11297 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
11298 ppos_it. Fixes vertical cursor motion when line beginning is
11299 covered by an image. (Bug#9296)
11301 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
11303 * nsterm.h (ns_run_ascript): Declare.
11304 (NSAPP_DATA2_RUNASSCRIPT): Define.
11306 * nsfns.m (as_script, as_result, as_status): New static variables.
11307 (ns_run_ascript): New function.
11308 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
11309 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
11310 the event loop. Get status from as_status (Bug#7276).
11312 * nsterm.m (sendEvent): If event is NSApplicationDefined and
11313 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
11314 the event loop (Bug#7276).
11316 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
11318 * gnutls.c (QCgnutls_bootprop_priority)
11319 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
11320 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
11321 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
11322 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
11323 (QCgnutls_bootprop_verify_hostname_error)
11324 (QCgnutls_bootprop_callbacks_verify): Rename from
11325 Qgnutls_bootprop_..., all uses changed.
11327 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
11330 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
11332 * xfaces.c (Qframe_set_background_mode): Now static.

11337 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
11339 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
11340 (Fnetwork_interface_list): Allocate in increments of bytes instead
11341 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
11342 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
11344 (struct ifflag_def): notrailers is smart on OSX.
11345 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
11346 Get hardware address with getifaddrs if available.
11348 2011-08-12 Eli Zaretskii <eliz@gnu.org>
11350 * xdisp.c (iterate_out_of_display_property): xassert that
11351 IT->position is set to within IT->object's boundaries. Break from
11352 the loop as soon as EOB is reached; avoids infloops in redisplay
11353 when IT->position is set up wrongly due to some bug.
11354 Set IT->current to match the bidi iterator unconditionally.
11355 (push_display_prop): Allow GET_FROM_STRING as IT->method on
11356 entry. Force push_it to save on the stack the current
11357 buffer/string position, to be restored by pop_it. Fix flags in
11358 the iterator structure wrt the object coming from a display
11359 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
11360 properties. (Bug#9284)
11362 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
11364 * fontset.c (fontset_get_font_group): Add proper type checks.
11367 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

11370 and LC_VERSION_MIN_MACOSX.
11371 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
11372 (dump_it) [LC_FUNCTION_STARTS]: Use it.
11374 2011-08-08 Eli Zaretskii <eliz@gnu.org>
11376 * xdisp.c (forward_to_next_line_start): Allow to use the
11377 no-display-properties-and-no-overlays under bidi display.
11378 Set disp_pos in the bidi iterator to avoid searches for display
11379 properties and overlays.
11381 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
11383 * editfns.c (Fset_time_zone_rule): Document relationship with the

11387 the font entity extracted from the cache (Bug#8109).
11389 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
11391 * composite.c (autocmp_chars): Don't reset point. That is done by
11392 restore_point_unwind (Bug#5984).
11394 2011-08-07 Juri Linkov <juri@jurta.org>
11396 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
11397 to show the arg `TIME' instead of `TIMEVAL'.
11399 2011-08-06 Eli Zaretskii <eliz@gnu.org>
11401 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
11402 display property strides EOL and includes a newline, as in
11403 longlines-mode. (Bug#9254)
11404 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
11405 word-wrap under bidirectional display. (Bug#9224)
11407 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
11408 is non-zero, even if the data buffer is NULL. Fixes a crash in
11409 vertical-motion with longlines-mode. (Bug#9254)
11411 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11413 * bidi.c <bidi_cache_total_alloc>: Now static.
11414 (bidi_initialize): Initialize bidi_cache_total_alloc.
11416 * xdisp.c (display_line): Release buffer allocated for shelved bidi
11419 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
11420 amount allocated this far in `bidi_cache_total_alloc'.
11421 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
11422 non-zero, only free the data buffer without restoring the cache
11423 contents. All callers changed.
11425 * dispextern.h (bidi_unshelve_cache): Update prototype.
11427 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
11428 (move_it_in_display_line, move_it_to)
11429 (move_it_vertically_backward, move_it_by_lines): Replace the call
11430 to xfree to an equivalent call to bidi_unshelve_cache.
11431 (move_it_in_display_line_to): Fix logic of returning
11432 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
11434 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11436 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
11437 came from a string character with a `cursor' property. (Bug#9229)
11439 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11441 * Makefile.in (LIB_PTHREAD): New variable.
11442 (LIBES): Add LIB_PTHREAD (Bug#9216).
11444 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
11445 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
11447 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
11449 * regex.c (re_iswctype): Remove some redundant boolean conversions.
11451 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11453 * xterm.c (x_find_topmost_parent): New function.
11454 (x_set_frame_alpha): Find topmost parent window with
11455 x_find_topmost_parent and set the property there also (bug#9181).
11456 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
11458 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
11460 * callproc.c (Fcall_process): Avoid vfork clobbering
11461 the local vars buffer, coding_systems, current_dir.
11463 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
11465 * keymap.c (Fmake_composed_keymap): Move to subr.el.
11467 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
11469 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
11470 so that it is not optimized away.
11472 * xdisp.c (compute_display_string_pos): Remove unused local.
11474 2011-08-02 Eli Zaretskii <eliz@gnu.org>
11476 Fix slow cursor motion and scrolling in large buffers with
11477 selective display, like Org Mode buffers. (Bug#9218)
11479 * dispextern.h (struct bidi_it): New member disp_prop_p.
11481 * xdisp.c: Remove one-slot cache of display string positions.
11482 (compute_display_string_pos): Accept an additional argument
11483 DISP_PROP_P; callers changed. Scan at most 5K characters forward
11484 for a display string or property. If found, set DISP_PROP_P
11487 * bidi.c (bidi_fetch_char): Accept an additional argument
11488 DISP_PROP_P, and pass it to compute_display_string_pos.
11489 Only handle text covered by a display string if DISP_PROP_P is returned
11490 non-zero. All callers of bidi_fetch_char changed.
11492 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
11494 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
11496 2010-12-03 Don March <don@ohspite.net>
11498 * keymap.c (Fdefine_key): Fix non-prefix key error message when
11499 last character M-[char] is translated to ESC [char] (bug#7541).
11501 2011-08-02 Kenichi Handa <handa@m17n.org>
11503 * lisp.h (uniprop_table): Extern it.
11505 * chartab.c (uniprop_table): Make it non-static.
11507 2011-08-01 Eli Zaretskii <eliz@gnu.org>
11509 * xdisp.c (forward_to_next_line_start): Accept additional argument
11510 BIDI_IT_PREV, and store into it the state of the bidi iterator had
11512 (reseat_at_next_visible_line_start): Use the bidi iterator state
11513 returned by forward_to_next_line_start to restore the state of
11514 it->bidi_it after backing up to previous newline. (Bug#9212)
11516 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
11518 * regex.c (re_comp): Protoize.
11519 (re_exec): Fix return type.
11520 (regexec): Fix type of `ret'. (Bug#9203)
11522 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11524 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
11525 This is needed if max-image-size is a floating-point number.
11527 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11529 * print.c (print_object): Print empty symbol as ##.
11531 * lread.c (read1): Read ## as empty symbol.
11533 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11535 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
11536 setting frame foreground color (Bug#9175).
11537 (x_set_background_color): Likewise.
11539 * nsmenu.m (-setText): Size tooltip dimensions precisely to
11540 contents (Bug#9176).
11541 (EmacsTooltip -init): Remove bezels and add shadows to
11544 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
11545 or scroll bar (Bug#8470).
11547 * nsfont.m (nsfont_open): Remove assignment to voffset and
11548 unnecessary vars hshink, expand, hd, full_height, min_height.
11549 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
11551 * nsterm.h (nsfont_info): Remove voffset field.
11553 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11555 Implement strike-through and overline on NextStep (Bug#8863).
11557 * nsfont.m (nsfont_open): Use underline position provided by font,
11558 instead of hard-coded value of 2.
11559 (nsfont_draw): Call ns_draw_text_decoration instead.
11561 * nsterm.h: Add declaration for ns_draw_text_decoration.
11563 * nsterm.m (ns_draw_text_decoration): New function for drawing
11564 underline, overline, and strike-through.
11565 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
11566 ns_draw_text_decoration. Change treatment of cursor drawing to
11567 accommodate underlining, etc.
11569 2011-07-28 Eli Zaretskii <eliz@gnu.org>
11571 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
11574 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11576 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11577 Without this fix, if a signal arrives just after memory fills up,
11578 'malloc' might be invoked reentrantly.
11580 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11581 In other words, assume that every image size is allowed, on non-X
11582 hosts. This assumption is probably wrong, but it lets Emacs compile.
11584 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11586 * regex.c (re_iswctype): Convert return values to boolean.
11588 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
11590 * xdisp.c (compute_display_string_pos): Don't use cached display
11591 string position if the buffer had its restriction changed.
11594 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11596 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11598 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11600 Integer signedness and overflow and related fixes. (Bug#9079)
11602 * bidi.c: Integer size and overflow fixes.
11603 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
11604 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
11605 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11606 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11607 (bidi_find_other_level_edge):
11608 Use ptrdiff_t instead of EMACS_INT where either will do.
11609 This works better on 32-bit hosts configured --with-wide-int.
11610 (bidi_cache_ensure_space): Check for size-calculation overflow.
11611 Use % rather than repeated addition, for better worst-case speed.
11612 Don't set bidi_cache_size until after xrealloc returns, because it
11614 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11615 (bidi_cache_ensure_space): Also check that the bidi cache size
11616 does not exceed that of the largest Lisp string or buffer. See Eli
11617 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11619 * alloc.c (__malloc_size_t): Remove.
11620 All uses replaced by size_t. See Andreas Schwab's note
11621 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11623 * image.c: Improve checking for integer overflow.
11624 (check_image_size): Assume that f is nonnull, since
11625 it is always nonnull in practice. This is one less thing to
11626 worry about when checking for integer overflow later.
11627 (x_check_image_size): New function, which checks for integer
11628 overflow issues inside X.
11629 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11630 This removes the need for a memory_full check.
11631 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11632 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11633 (xbm_read_bitmap_data): Change locals back to 'int', since
11634 their values must fit in 'int'.
11635 (xpm_load_image, png_load, tiff_load):
11636 Invoke x_create_x_image_and_pixmap earlier,
11637 to avoid much needless work if the image is too large.
11638 (tiff_load): Treat overly large images as if
11639 x_create_x_image_and_pixmap failed, not as malloc failures.
11640 (gs_load): Use x_check_image_size.
11642 * gtkutil.c: Omit integer casts.
11643 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11644 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11646 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11648 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11649 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11650 would wrongly return t on a 64-bit host.
11652 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11653 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11654 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11655 and therefore cause GCC to emit a bogus diagnostic in some cases.
11657 * image.c: Integer signedness and overflow and related fixes.
11658 This is not an exhaustive set of fixes, but it's time to
11659 record what I've got.
11660 (lookup_pixel_color, check_image_size): Remove redundant decls.
11661 (check_image_size): Don't assume that arbitrary EMACS_INT values
11662 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11663 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11664 (tiff_load, imagemagick_load_image):
11665 Check for overflow in size calculations.
11666 (x_create_x_image_and_pixmap): Remove unnecessary test for
11667 xmalloc returning NULL; that can't happen.
11668 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11669 (xpm_color_bucket): Use better integer hashing function.
11670 (xpm_cache_color): Don't possibly over-allocate memory.
11671 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11672 (gif_memory_source):
11673 Use ptrdiff_t, not int or size_t, to record sizes.
11674 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11675 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11676 either works, as we prefer signed integers.
11677 (tiff_read_from_memory, tiff_write_from_memory):
11678 Return tsize_t, not size_t, since that's what the TIFF API wants.
11679 (tiff_read_from_memory): Don't fail simply because the read would
11680 go past EOF; instead, return a short read.
11681 (tiff_load): Omit no-longer-needed casts.
11682 (Fimagemagick_types): Don't assume size fits into 'int'.
11684 Improve hashing quality when configured --with-wide-int.
11685 * fns.c (hash_string): New function, taken from sxhash_string.
11686 Do not discard information about ASCII character case; this
11687 discarding is no longer needed.
11688 (sxhash-string): Use it. Change sig to match it. Caller changed.
11689 * lisp.h: Declare it.
11690 * lread.c (hash_string): Remove, since we now use fns.c's version.
11691 The fns.c version returns a wider integer if --with-wide-int is
11692 specified, so this should help the quality of the hashing a bit.
11694 * emacs.c: Integer overflow minor fix.
11695 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11696 Define only if GNU_LINUX.
11697 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11699 * dispnew.c: Integer signedness and overflow fixes.
11700 Remove unnecessary forward decls, that were a maintenance hassle.
11701 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11703 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11704 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11705 (prepare_desired_row, line_draw_cost):
11706 Use int, not unsigned, where either works.
11707 (save_current_matrix, restore_current_matrix):
11708 Use ptrdiff_t, not size_t, where either works.
11709 (init_display): Check for overflow more accurately, and without
11710 relying on undefined behavior.
11712 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11713 Remove, replacing with the new symbols in lisp.h. All uses changed.
11714 * fileio.c (make_temp_name):
11715 * filelock.c (lock_file_1, lock_file):
11716 * xdisp.c (message_dolog):
11717 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11718 Use pMd etc. instead.
11719 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11720 replacing the pWIDE etc. symbols removed from editfns.c.
11722 * keyboard.h (num_input_events): Now uintmax_t.
11723 This is (very slightly) less likely to mess up due to wraparound.
11726 * buffer.c: Integer signedness fixes.
11727 (alloc_buffer_text, enlarge_buffer_text):
11728 Use ptrdiff_t rather than size_t when either will do, as we prefer
11731 * alloc.c: Integer signedness and overflow fixes.
11732 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11733 (__malloc_size_t): Default to size_t, not to int.
11734 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11735 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11736 Prefer ptrdiff_t to size_t when either would do, as we prefer
11738 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11739 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11740 Now const. Initialize with values that are in range even if char
11742 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11743 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11744 These functions do the right thing with sizes > 2**32.
11745 (check_depth): Now ptrdiff_t, not int.
11746 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11747 Adjust to new way of storing sizes. Check for size overflow bugs
11749 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11750 slightly wrong anyway, as it missed one instance of
11751 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11752 (refill_memory_reserve): Omit needless cast to size_t.
11753 (mark_object_loop_halt): Mark as externally visible.
11755 * xselect.c: Integer signedness and overflow fixes.
11756 (Fx_register_dnd_atom, x_handle_dnd_message):
11757 Use ptrdiff_t, not size_t, since we prefer signed.
11758 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11759 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11760 x_dnd_atoms_size and x_dnd_atoms_length.
11762 * doprnt.c: Prefer signed to unsigned when either works.
11764 * doprnt.c (doprnt):
11766 * xdisp.c (vmessage):
11767 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11768 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11769 prefer signed arithmetic to avoid comparison confusion.
11770 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11771 but is a bit tricky.
11773 Assume freestanding C89 headers, string.h, stdlib.h.
11774 * data.c, doprnt.c, floatfns.c, print.c:
11775 Include float.h unconditionally.
11776 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11777 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11778 * regex.c: Likewise for stddef.h, string.h.
11779 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11780 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11781 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11782 (STDC_HEADERS): Remove obsolete defines.
11783 * sysdep.c: Include limits.h unconditionally.
11785 Assume support for memcmp, memcpy, memmove, memset.
11786 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11787 * regex.c (memcmp, memcpy):
11788 Remove; we assume C89 now.
11790 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11791 (__malloc_safe_bcopy): Remove; no longer needed.
11793 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11794 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11795 well either way, and we prefer signed to unsigned.
11797 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11799 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11800 closes the connection while we're reading (bug#9182).
11802 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11804 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11805 are specified (Bug#9168).
11807 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11809 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11810 Found by GCC static checking and --with-wide-int on a 32-bit host.
11812 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11814 * xdisp.c (compute_display_string_pos): Fix logic of caching
11815 previous display string position. Initialize cached_prev_pos to
11816 -1. Fixes slow-down at the beginning of a buffer.
11818 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11820 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11821 for attrs[LFACE_FONTSET_INDEX].
11823 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11825 * xml.c (parse_region): Remove unused local
11826 that was recently introduced.
11828 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11830 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11831 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11833 * xdisp.c (move_it_in_display_line_to): Record the best matching
11834 position for TO_CHARPOS while scanning the line, and restore it on
11835 exit if none of the characters scanned was an exact match.
11836 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11837 when exact match is impossible due to invisible text, and the
11838 lines are truncated.
11840 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11842 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11845 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11847 Fix a significant slow-down of cursor motion with C-n, C-p,
11848 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11849 auto-repeat under bidi redisplay in fontified buffers.
11850 * xdisp.c (compute_stop_pos_backwards): New function.
11851 (next_element_from_buffer): Call compute_stop_pos_backwards to
11852 find a suitable prev_stop when we find ourselves before
11854 (reseat): Don't look for prev_stop, as that could mean a very long
11856 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11857 <cached_disp_overlay_modiff>: Cache for last found display string
11859 (compute_display_string_pos): Return the cached position if asked
11860 about the same buffer in the same area of character positions, and
11861 the buffer wasn't changed since the time the display string
11862 position was cached.
11864 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11866 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11867 is an integer, which is important for empty lines. (Bug#9149)
11869 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11871 * frame.c (Fmodify_frame_parameters): In tty case, update the
11872 default face if necessary (Bug#4238).
11874 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11876 * editfns.c (Fstring_to_char): No need to explain what a character
11877 is in the docstring (Bug#6576).
11879 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11881 * xml.c (parse_region): Make sure we always return a tree.
11883 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11885 * xml.c (parse_region): If a document contains only comments,
11888 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11890 * xml.c (make_dom): Return comments, too.
11892 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11895 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11896 and the surrounding thread.
11897 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11898 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11899 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11901 * s/openbsd.h (BROKEN_SIGIO): Define.
11902 * unexelf.c (unexec) [__OpenBSD__]:
11903 Don't update the .mdebug section of the Alpha COFF symbol table.
11905 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11907 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11910 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11912 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11913 This fixes some race conditions on the permissions of any newly
11916 * alloc.c (valid_pointer_p): Use pipe, not open.
11917 This fixes some permissions issues when debugging.
11919 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11920 If fchown fails to set both uid and gid, try to set just gid,
11921 as that is sometimes allowed. Adjust the file's mode to eliminate
11922 setuid or setgid bits that are inappropriate if fchown fails.
11924 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11926 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11927 to compare Lisp_Objects.
11928 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11929 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11930 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11932 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11934 * lread.c (read_integer): Unread even EOF character.
11935 (read1): Likewise. Properly record start position of symbol.
11937 * lread.c (read1): Read `#:' as empty uninterned symbol if no
11938 symbol character follows.
11940 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11942 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11943 This works around a problem with the previous change to Fcopy_file.
11944 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11945 and without this change, GCC might complain about discarding
11946 fchown's return value.
11948 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11950 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11952 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11954 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11956 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11958 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11959 it's used from the C level.
11961 * process.c: Use the same condition for POLL_FOR_INPUT in both
11962 keyboard.c and process.c (bug#1858).
11964 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11966 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11967 (Fgnutls_boot): Use it.
11969 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11971 * doc.c (Fsubstitute_command_keys): Revert last change.
11973 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11975 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11976 quotes the next character, and doesn't affect other longer
11977 sequences (bug#8935).
11979 * lread.c (syms_of_lread): Clarify that is isn't only
11980 `eval-buffer' and `eval-defun' that's affected by
11981 `lexical-binding' (bug#8460).
11983 2011-07-15 Eli Zaretskii <eliz@gnu.org>
11985 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11986 bidi redisplay when a line includes both an image and is truncated.
11988 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11990 Fix minor problems found by static checking.
11991 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11992 (elsz): Now a signed constant, not a size_t var. We prefer signed
11993 types to unsigned, to avoid integer comparison confusion. Without
11994 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
11995 "cannot optimize loop, the loop counter may overflow", a symptom
11997 * indent.c (Fvertical_motion): Mark locals as initialized.
11998 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
12000 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
12002 * search.c (Fre_search_backward): Mention `case-fold-search' in
12003 all the re_search_* functions (bug#8138).
12005 * keyboard.c (Fopen_dribble_file): Document when the file is
12008 2011-07-14 Eli Zaretskii <eliz@gnu.org>
12010 * bidi.c (bidi_dump_cached_states): Fix format of displaying
12013 Support bidi reordering of display and overlay strings.

12016 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
12017 (reseat_to_string): Initialize bidi_it->string.s and
12018 bidi_it->string.schars.
12019 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
12020 NULL (avoids a crash in bidi_paragraph_init).
12021 Initialize itb.string.lstring.
12022 (init_iterator): Call bidi_init_it only of a valid
12023 buffer position was specified. Initialize paragraph_embedding to
12025 (reseat_to_string): Initialize the bidi iterator.
12026 (display_string): If we need to ignore text properties of
12027 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
12028 original value of -1 will not work with bidi.)
12029 (compute_display_string_pos): First arg is now struct
12030 `text_pos *'; all callers changed. Support display properties on
12032 (compute_display_string_end): Support display properties on Lisp
12034 (init_iterator, reseat_1, reseat_to_string): Initialize the
12035 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
12036 when iterating on a string not from display properties).
12037 (compute_display_string_pos, compute_display_string_end):
12038 Fix calculation of the object to scan. Fixes an error when using
12040 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
12041 base_level_stop; instead, set base_level_stop to BEGV.
12042 Fixes crashes in vertical-motion.
12043 (next_element_from_buffer): Improve commentary for when
12044 the iterator is before prev_stop.
12045 (init_iterator): Initialize bidi_p from the default value of
12046 bidi-display-reordering, not from buffer-local value. Use the
12047 buffer-local value only if initializing for buffer iteration.
12048 (handle_invisible_prop): Support invisible properties on strings
12049 that are being bidi-reordered.
12050 (set_iterator_to_next): Support bidi reordering of C strings and
12052 (next_element_from_string): Support bidi reordering of Lisp
12054 (handle_stop_backwards): Support Lisp strings as well.
12055 (display_string): Support display of R2L glyph rows.
12056 Use IT_STRING_CHARPOS when displaying from a Lisp string.
12057 (init_iterator): Don't initialize it->bidi_p for strings
12059 (reseat_to_string): Initialize it->bidi_p for strings here.
12060 (next_element_from_string, next_element_from_c_string)
12061 (next_element_from_buffer): Add xassert's for correspondence
12062 between IT's object being iterated and it->bidi_it.string
12064 (face_before_or_after_it_pos): Support bidi iteration.
12065 (next_element_from_c_string): Handle the case of the first string
12066 character that is not the first one in the visual order.
12067 (get_visually_first_element): New function, refactored from common
12068 parts of next_element_from_buffer, next_element_from_string, and
12069 next_element_from_c_string.
12070 (tool_bar_lines_needed, redisplay_tool_bar)
12071 (display_menu_bar): Force left-to-right direction. Add a FIXME
12072 comment for making that be controlled by a user option.
12073 (push_it, pop_it): Save and restore the state of the
12074 bidi iterator. Save and restore the bidi_p flag.
12075 (pop_it): Iterate out of display property for string iteration as
12077 (iterate_out_of_display_property): Support iteration over strings.
12078 (handle_single_display_spec): Set up it->bidi_it for iteration
12079 over a display string, and call bidi_init_it.
12080 (handle_single_display_spec, next_overlay_string)
12081 (get_overlay_strings_1, push_display_prop): Set up the bidi
12082 iterator for displaying display or overlay strings.
12083 (forward_to_next_line_start): Don't use the shortcut if
12085 (back_to_previous_visible_line_start): If handle_display_prop
12086 pushed the iterator stack, restore the internal state of the bidi
12087 iterator by calling bidi_pop_it same number of times.
12088 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
12089 and we are bidi-iterating, don't decrement the iterator position;
12090 instead, set the first_elt flag in the bidi iterator, to produce
12092 (reseat_1): Remove redundant setting of string_from_display_prop_p.
12093 (push_display_prop): xassert that we are iterating a buffer.
12094 (push_it, pop_it): Save and restore paragraph_embedding member.
12095 (handle_single_display_spec, next_overlay_string)
12096 (get_overlay_strings_1, reseat_1, reseat_to_string)
12097 (push_display_prop): Set up the `unibyte' member of bidi_it.string
12098 correctly. Don't assume unibyte strings are not bidi-reordered.
12099 (compute_display_string_pos)
12100 (compute_display_string_end): Fix handling the case of C string.
12101 (push_it, pop_it): Save and restore from_disp_prop_p.
12102 (handle_single_display_spec, push_display_prop): Set the
12103 from_disp_prop_p flag.
12104 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
12105 (pop_it): Call iterate_out_of_display_property only if we are

12561 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
12563 Random fixes. E.g., (random) never returned negative values.
12564 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
12565 subseconds part to the entropy, as that's a bit more random.
12566 Prefer signed to unsigned, since the signedness doesn't matter and
12567 in general we prefer signed. When given a limit, use a
12568 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12569 latter isn't right if USE_2_TAGS_FOR_INTS.
12570 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12571 not 0..VALMASK. Don't discard "excess" bits that random () returns.
12573 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
12575 * textprop.c (text_property_stickiness):
12576 Obey Vtext_property_default_nonsticky.

12583 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
12584 This is more efficient than Ffile_directory_p and avoids a minor race.
12586 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
12588 * buffer.c (Foverlay_put): Say what the return value is
12591 * fileio.c (barf_or_query_if_file_exists): Check first if the file
12592 is a directory before asking whether to use the file name
12594 (barf_or_query_if_file_exists): Make the "File is a directory"
12595 error be more correct.
12597 * fns.c (Frequire): Remove the mention of the .gz files, since
12598 that's installation-specific, but keep the mention of
12599 `get-load-suffixes'.
12601 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
12603 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

12608 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
12609 (syms_of_gnutls): Remove duplicate DEFSYM for
12610 Qgnutls_bootprop_verify_hostname_error, an error for
12611 Qgnutls_bootprop_verify_error (which is no longer used).
12613 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
12614 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
12615 Also (re)move comments that are misplaced or no longer relevant.
12617 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12619 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

12647 * fns.c (Frequire): Mention .el.gz files (bug#7314).
12648 (Frequire): Mention get-load-suffixes.

12716 * eval.c (struct backtrace): Simplify and port the data structure.
12717 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12718 signed bit field, as this assumption is not portable and it makes
12719 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12720 "char debug_on_exit : 1" as this is not portable either; instead,
12721 use the portable "unsigned int debug_on_exit : 1". Remove unused
12722 member evalargs. Remove obsolete comments about cc bombing out.
12724 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

12793 (emacs_fixed_get_preferred_width)
12794 (emacs_fixed_get_preferred_height): Use min_width/height from
12795 frames size_hint to set minimum and natural (Bug#8919).
12796 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
12797 and use min_width/height from frames size_hint to set
12798 min_width/height (Bug#8919).

12890 * print.c (printchar, strout): Check for string overflow.
12891 (PRINTPREPARE, printchar, strout):
12892 Don't set size unless allocation succeeds.
12894 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
12895 for sizes. Check for string overflow more accurately.

12909 (read_integer): Radix is now EMACS_INT, not int,
12910 to improve quality of diagnostics for out-of-range radices.
12911 Calculate buffer size correctly for out-of-range radices.
12912 (read1): Check for integer overflow in radices, and in
12913 read-circle numbers.
12914 (read_escape): Avoid int overflow.
12915 (Fload, openp, read_buffer_size, read1)
12916 (substitute_object_recurse, read_vector, read_list, map_obarray):
12917 Use ptrdiff_t, not int, for sizes.

12939 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
12940 The following patches are for when GLYPH_DEBUG && !XASSERT.
12941 * dispextern.h (trace_redisplay_p, dump_glyph_string):
12942 * dispnew.c (flush_stdout):
12943 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
12944 Mark as externally visible.
12945 * dispnew.c (check_window_matrix_pointers): Now static.
12946 * dispnew.c (window_to_frame_vpos):
12947 * xfns.c (unwind_create_frame):
12948 * xterm.c (x_check_font): Remove unused local.
12949 * scroll.c (CHECK_BOUNDS):
12950 * xfaces.c (cache_fache): Rename local to avoid shadowing.
12951 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.

12953 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
12954 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
12956 (debug_method_add): Use va_list and vsprintf rather than relying
12957 on undefined behavior with wrong number of arguments.
12958 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12959 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12960 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12961 since we're not interested in debugging glyphs with old libraries.
12962 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12963 GCC 4.6.0's static checking.
12965 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12967 Integer overflow and signedness fixes (Bug#8873).

12982 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
12983 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
12984 (.bitmaps_last, struct x_output.icon_bitmap):
12985 Use ptrdiff_t, not int, for bitmap indexes.
12986 (x_allocate_bitmap_record): Check for size overflow.
12987 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
12989 Use ptrdiff_t, not int, for overlay counts.
12990 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
12991 * editfns.c (overlays_around, get_pos_property):
12992 * textprop.c (get_char_property_and_overlay):
12993 * xdisp.c (next_overlay_change, note_mouse_highlight):
12994 * xfaces.c (face_at_buffer_position):
12995 * buffer.c (OVERLAY_COUNT_MAX): New macro.
12996 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
12997 (Fnext_overlay_change, Fprevious_overlay_change)
12998 (mouse_face_overlay_overlaps, Foverlays_in):
12999 Use ptrdiff_t, not int, for sizes.
13000 (overlays_at, overlays_in): Check for size-calculation overflow.
13002 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
13004 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
13005 (x_session_initialize): Do not assume string length fits in int.
13007 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
13008 This is unlikely, but can occur if DPI is outlandish.
13010 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
13011 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
13013 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
13014 * xrdb.c (magic_file_p, search_magic_path):
13015 Omit last arg SUFFIX; it was always 0. All callers changed.
13016 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
13018 * xfont.c (xfont_match): Avoid need for strlen.
13020 * xfns.c: Don't assume strlen fits in int.
13021 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
13023 * xdisp.c (message_log_check_duplicate): Return intmax_t,
13024 not unsigned long, as we prefer signed integers. All callers changed.
13025 Detect integer overflow in repeat count.
13026 (message_dolog): Don't assume print length fits in 39 bytes.
13027 (display_mode_element): Don't assume strlen fits in int.
13029 * termcap.c: Don't assume sizes fit in int and never overflow.
13030 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
13031 (gobble_line): Check for size-calculation overflow.
13033 * minibuf.c (Fread_buffer):
13034 * lread.c (intern, intern_c_string):
13035 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
13036 Don't assume string length fits in int.
13038 * keyboard.c (parse_tool_bar_item):
13039 * gtkutil.c (style_changed_cb): Avoid need for strlen.
13041 * font.c: Don't assume string length fits in int.
13042 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
13043 Use ptrdiff_t, not int.
13044 (font_intern_prop): Don't assume string length fits in int.
13045 Don't assume integer property fits in fixnum.
13046 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
13048 * filelock.c: Fix some buffer overrun and integer overflow issues.
13049 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
13050 Reformulate so as not to need the command string.
13051 Invoke gzip -cd rather than gunzip, as it's more portable.
13052 (lock_info_type, lock_file_1, lock_file):
13053 Don't assume pid_t and time_t fit in unsigned long.
13054 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
13055 (current_lock_owner): Prefer signed type for sizes.
13056 Use memcpy, not strncpy, where memcpy is what is really wanted.
13057 Don't assume (via atoi) that time_t and pid_t fit in int.
13058 Check for time_t and/or pid_t out of range, e.g., via a network share.
13059 Don't alloca where an auto var works fine.
13061 * fileio.c: Fix some integer overflow issues.
13062 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
13063 Don't assume string length fits in int.
13064 (directory_file_name): Don't assume string length fits in long.
13065 (make_temp_name): Don't assume pid fits in int, or that its print
13066 length is less than 20.
13068 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
13070 * coding.c (make_subsidiaries): Don't assume string length fits in int.
13072 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
13074 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
13075 We prefer signed integers, even for size calculations.
13077 * emacs.c: Don't assume string length fits in 'int'.
13078 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
13079 (main): Don't invoke strlen when not needed.
13081 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
13082 (XD_DEBUG_MESSAGE): Don't waste a byte.
13084 * callproc.c (getenv_internal_1, getenv_internal)
13085 (Fgetenv_internal):
13086 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
13088 * lread.c (invalid_syntax): Omit length argument.
13089 All uses changed. This doesn't fix a bug, but it simplifies the
13090 code away from its former Hollerith-constant appearance, and it's
13091 one less 'int' to worry about when looking at integer-overflow issues.
13092 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
13094 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
13095 This didn't break anything, but it didn't help either.
13096 It's confusing to put a bogus integer in a place where the actual
13097 value does not matter.
13098 (LIST_END_P): Remove unused macro and its bogus comment.
13099 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
13101 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
13102 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
13104 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
13105 We prefer signed types, and the value cannot exceed the EMACS_INT
13106 range anyway (because otherwise the length would not be representable).
13107 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
13108 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
13109 This avoids a GCC warning when WIDE_EMACS_INT.
13111 * indent.c (sane_tab_width): New function.
13112 (current_column, scan_for_column, Findent_to, position_indentation)
13113 (compute_motion): Use it. This is just for clarity.
13114 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
13116 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
13118 * lisp.h (lint_assume): New macro.
13119 * composite.c (composition_gstring_put_cache):
13120 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
13122 * editfns.c, insdel.c:
13123 Omit unnecessary forward decls, to simplify future changes.
13125 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
13127 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
13129 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
13130 Use much-faster test for byte-length change.
13131 Don't assume string byte-length fits in 'int'.
13132 Check that character arg fits in 'int'.
13133 (mapcar1): Declare byte as byte, for clarity.
13135 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
13137 * fns.c (concat): Catch string overflow earlier.
13138 Do not rely on integer wraparound.
13140 * dispextern.h (struct it.overlay_strings_charpos)
13141 (struct it.selective): Now EMACS_INT, not int.
13142 * xdisp.c (forward_to_next_line_start)
13143 (back_to_previous_visible_line_start)
13144 (reseat_at_next_visible_line_start, next_element_from_buffer):
13145 Don't arbitrarily truncate the value of 'selective' to int.
13147 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
13149 * composite.c: Don't truncate sizes to 'int'.
13150 (composition_gstring_p, composition_reseat_it)
13151 (composition_adjust_point): Use EMACS_INT, not int.
13152 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
13153 not EMACS_UINT, for indexes.
13155 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
13157 * buffer.c: Include <verify.h>.
13158 (struct sortvec.priority, struct sortstr.priority):
13159 Now EMACS_INT, not int.
13160 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
13161 (struct sortstr.size, record_overlay_string)
13162 (struct sortstrlist.size, struct sortlist.used):
13163 Don't truncate size to int.
13164 (record_overlay_string): Check for size-calculation overflow.
13165 (init_buffer_once): Check at compile-time, not run-time.
13167 2011-06-22 Jim Meyering <meyering@redhat.com>
13169 Don't leak an XBM-image-sized buffer
13170 * image.c (xbm_load): Free the image buffer after using it.
13172 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
13175 * composite.c (find_automatic_composition): Omit needless 'return 0;'
13176 that Sun C diagnosed.
13177 * fns.c (secure_hash): Fix pointer signedness issue.
13178 * intervals.c (static_offset_intervals): New function.
13179 (offset_intervals): Use it.
13181 2011-06-21 Leo Liu <sdl.web@gmail.com>
13184 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
13187 * fns.c (secure_hash): Rename from crypto_hash_function and change
13188 the first arg to accept symbols.
13189 (Fsecure_hash): New primitive.
13190 (syms_of_fns): New symbols.
13192 2011-06-20 Deniz Dogan <deniz@dogan.se>
13194 * process.c (Fset_process_buffer): Clarify return value in
13197 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
13199 * dispnew.c (add_window_display_history): Use BVAR.
13201 * xdisp.c (debug_method_add): Use BVAR.
13202 (check_window_end, dump_glyph_matrix, dump_glyph)
13203 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
13205 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
13208 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
13209 check till after the cache is created in init_frame_faces.
13211 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
13213 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
13215 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
13217 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
13218 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
13219 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
13221 Improve buffer-overflow checking (Bug#8873).
13222 * fileio.c (Finsert_file_contents):
13223 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
13224 Remove the old (too-loose) buffer overflow checks.
13225 They weren't needed, since make_gap checks for buffer overflow.
13226 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
13227 The old code merely checked for Emacs fixnum overflow, and relied
13228 on undefined (wraparound) behavior. The new code avoids undefined
13229 behavior, and also checks for ptrdiff_t and/or size_t overflow.
13231 * editfns.c (Finsert_char): Don't dump core with very negative counts.
13232 Tune. Don't use wider integers than needed. Don't use alloca.
13233 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
13235 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
13237 * insdel.c, lisp.h (buffer_overflow): New function.
13238 (insert_from_buffer_1, replace_range, replace_range_2):
13239 * insdel.c (make_gap_larger):
13240 * editfns.c (Finsert_char):
13241 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
13243 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
13245 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
13247 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
13249 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
13250 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
13252 * fileio.c: Don't assume EMACS_INT fits in off_t.
13253 (emacs_lseek): New static function.
13254 (Finsert_file_contents, Fwrite_region): Use it.
13255 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
13257 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
13259 * fns.c: Don't overflow int when computing a list length.
13260 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
13261 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
13262 truncation on 64-bit hosts. Check for QUIT every
13263 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
13264 faster and is responsive enough.
13265 (Flength): Report an error instead of overflowing an integer.
13266 (Fsafe_length): Return a float if the value is not representable
13267 as a fixnum. This shouldn't happen except in contrived situations.
13268 (Fnthcdr, Fsort): Don't assume list length fits in int.
13269 (Fcopy_sequence): Don't assume vector length fits in int.
13271 * alloc.c: Check that resized vectors' lengths fit in fixnums.
13272 (header_size, word_size): New constants.
13273 (allocate_vectorlike): Don't check size overflow here.
13274 (allocate_vector): Check it here instead, since this is the only
13275 caller of allocate_vectorlike that could cause overflow.
13276 Check that the new vector's length is representable as a fixnum.
13278 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
13279 The previous code was bogus. For example, next_almost_prime (32)
13280 returned 39, which is undesirable as it is a multiple of 3; and
13281 next_almost_prime (24) returned 25, which is a multiple of 5 so
13282 why was the code bothering to check for multiples of 7?
13284 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
13286 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
13288 Variadic C functions now count arguments with ptrdiff_t.
13289 This partly undoes my 2011-03-30 change, which replaced int with size_t.
13290 Back then I didn't know that the Emacs coding style prefers signed int.
13291 Also, in the meantime I found a few more instances where arguments
13292 were being counted with int, which may truncate counts on 64-bit
13293 machines, or EMACS_INT, which may be unnecessarily wide.
13294 * lisp.h (struct Lisp_Subr.function.aMANY)
13295 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
13296 Arg counts are now ptrdiff_t, not size_t.
13297 All variadic functions and their callers changed accordingly.
13298 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
13299 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
13300 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
13301 * callint.c (Fcall_interactively): Check arg count for overflow,
13302 to avoid potential buffer overrun. Use signed char, not 'int',
13303 for 'varies' array, so that we needn't bother to check its size
13304 calculation for overflow.
13305 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
13306 * eval.c (apply_lambda):
13307 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
13308 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
13309 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
13311 * callint.c (Fcall_interactively): Don't use index var as event count.
13313 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
13314 * mem-limits.h (SIZE): Remove; no longer used.
13316 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
13318 Remove unnecessary casts.
13319 * xterm.c (x_term_init):
13320 * xfns.c (x_set_border_pixel):
13321 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
13322 These aren't needed now that we assume ANSI C.
13324 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
13325 It's more likely to cause problems (due to unsigned overflow)
13328 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
13330 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
13332 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
13334 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
13336 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
13338 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
13340 GLYPH_CODE_FACE returns EMACS_INT, not int.
13341 * dispextern.h (merge_faces):
13342 * xfaces.c (merge_faces):
13343 * xdisp.c (get_next_display_element, next_element_from_display_vector):
13344 Don't assume EMACS_INT fits in int.
13346 * character.h (CHAR_VALID_P): Remove unused parameter.
13347 * fontset.c, lisp.h, xdisp.c: All uses changed.
13349 * editfns.c (Ftranslate_region_internal): Omit redundant test.
13351 * fns.c (concat): Minor tuning based on overflow analysis.
13352 This doesn't fix any bugs. Use int to hold character, instead
13353 of constantly refetching from Emacs object. Use XFASTINT, not
13354 XINT, for value known to be a character. Don't bother comparing
13355 a single byte to 0400, as it's always less.
13357 * floatfns.c (Fexpt):
13358 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
13360 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
13363 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
13365 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
13366 Without this fix, on a 64-bit host (aset S 0 4294967386) would
13367 incorrectly succeed when S was a string, because 4294967386 was
13368 truncated before it was used.
13370 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13371 Otherwise, an out-of-range integer could cause undefined behavior
13374 * composite.c: Use int, not EMACS_INT, for characters.
13375 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13376 EMACS_INT, for values that are known to be in character range.
13377 This doesn't fix any bugs but is the usual style inside Emacs and
13378 may generate better code on 32-bit machines.
13380 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13381 This is for reasons similar to the recent CHAR_STRING fix.
13382 * charset.c (Fencode_char): Check that character arg is actually
13383 a character. Pass an int to ENCODE_CHAR.
13384 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13385 wider than 'int', as a compile-time check to prevent future regressions
13388 * character.c (char_string): Remove unnecessary casts.
13390 Make sure a 64-bit char is never passed to CHAR_STRING.
13391 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13392 by silently ignoring the top 32 bits, allowing some values
13393 that were far too large to be valid characters.
13394 * character.h: Include <verify.h>.
13395 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13396 arguments are no wider than unsigned, as a compile-time check
13397 to prevent future regressions in this area.
13399 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
13400 (Fsubst_char_in_region):
13402 * xdisp.c (decode_mode_spec_coding):
13403 Adjust to CHAR_STRING's new requirement.
13404 * editfns.c (Finsert_char, Fsubst_char_in_region):
13405 * fns.c (concat): Check that character args are actually
13406 characters. Without this test, these functions did the wrong
13407 thing with wildly out-of-range values on 64-bit hosts.
13409 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13410 These casts should not be needed on 32-bit hosts, either.
13411 * keyboard.c (read_char):
13412 * lread.c (Fload): Remove casts to unsigned.
13414 * lisp.h (UNSIGNED_CMP): New macro.
13415 This fixes comparison bugs on 64-bit hosts.
13416 (ASCII_CHAR_P): Use it.
13417 * casefiddle.c (casify_object):
13418 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
13419 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
13420 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
13421 * dispextern.h (FACE_FROM_ID):
13422 * keyboard.c (read_char): Use UNSIGNED_CMP.
13424 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,

13472 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13473 when a (possibly-narrower) signed value would do just as well.
13474 We prefer using signed arithmetic, to avoid comparison confusion.
13476 * alloc.c: Catch some string size overflows that we were missing.
13477 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
13478 for convenience in STRING_BYTES_MAX.
13479 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
13480 The definition here is exact; the one in lisp.h was approximate.
13481 (allocate_string_data): Check for string overflow. This catches
13482 some instances we weren't catching before. Also, it catches
13483 size_t overflow on (unusual) hosts where SIZE_MAX <= min
13484 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
13485 and ptrdiff_t and EMACS_INT are both 64 bits.
13487 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
13488 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.

14066 instead of using explicit *_CHAR codes.
14067 (bidi_resolve_explicit, bidi_resolve_weak):

14076 (bidi_level_of_next_char): Don't try to lookup the cache for the
14077 next/previous character if nothing is cached there yet, or if we
14078 were just reseat()'ed to a new position.
14080 * xdisp.c (set_cursor_from_row): Set start and stop points
14081 according to the row's direction when priming the loop that looks
14082 for the glyph on which to display cursor.

14084 (display_prop_intangible_p): Reimplement to call
14085 handle_display_spec instead of single_display_spec_intangible_p.
14086 Accept 3 additional arguments needed by handle_display_spec.
14087 This fixes incorrect cursor motion across display property with complex

14096 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
14097 value of a `display' property is a "replacing spec".
14098 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
14099 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
14100 the display property, but just return a value indicating whether
14101 the display property will replace the characters it covers.
14102 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
14103 frame_window_p members of struct bidi_it.

14127 All callers changed. (Bug#8762)
14129 * gnutls.c: Use Emacs's memory allocators.
14130 Without this change, the gnutls library would invoke malloc etc.
14131 directly, which causes problems on non-SYNC_INPUT hosts, and which
14132 runs afoul of improving memory_full behavior. (Bug#8761)
14133 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
14134 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
14135 xfree instead of the default malloc, realloc, free.
14136 (Fgnutls_boot): No need to check for memory allocation failure,
14137 since xmalloc does that for us.

14160 for hashes and hash indexes, instead of 'unsigned' and 'int'.
14161 * alloc.c (allocate_vectorlike):
14162 Check for overflow in vector size calculations.
14163 * ccl.c (ccl_driver):
14164 Check for overflow when converting EMACS_INT to int.

14166 need to be updated by these changes.
14167 * fns.c (make_hash_table, maybe_resize_hash_table):
14168 Check for integer overflow with large hash tables.
14169 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
14170 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
14171 (SXHASH_REDUCE): New macro.
14172 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
14173 Use it instead of discarding useful hash info with large hash values.
14174 (sxhash_float): New function.
14175 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
14176 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
14177 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
14178 Rewrite to use FIXNUM_BITS, as this simplifies things.
14179 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
14180 Adjust signatures to match updated version of code.
14181 (consing_since_gc): Now EMACS_INT, since a single hash table can
14182 use more than INT_MAX bytes.

14231 Make it possible to run ./temacs.
14233 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
14234 syms_of_callproc does the same thing. Remove test for

14296 (crypto_hash_function): Use it to convert some newly-signed
14297 variables to unsigned, to avoid sign-extension bugs. For example,
14298 without this change, (md5 "truc") would evaluate to
14299 45723a2aff78ff4fff7fff1114760e62 rather than the expected
14300 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
14301 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
14303 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14305 Integer overflow fixes.
14307 * dbusbind.c: Serial number integer overflow fixes.
14308 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
14309 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
14310 to hold a serial number that is too large for a fixnum.
14311 (Fdbus_method_return_internal, Fdbus_method_error_internal):
14312 Check for serial numbers out of range. Decode any serial number
14313 that was so large that it became a float. (Bug#8722)
14315 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
14316 (Fdbus_call_method, Fdbus_call_method_asynchronously):
14317 Use XFASTINT rather than XUINT when numbers are nonnegative.
14318 (xd_append_arg, Fdbus_method_return_internal):
14319 (Fdbus_method_error_internal): Likewise. Also, for unsigned
14320 arguments, check that Lisp number is nonnegative, rather than
14321 silently wrapping negative numbers around. (Bug#8722)
14322 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
14325 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
14327 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
14329 ccl: Add integer overflow checks.
14330 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
14331 (IN_INT_RANGE): New macros.
14332 (ccl_driver): Use them to check for integer overflow when
14333 decoding a CCL program. Many of the new checks are whether XINT (x)
14334 fits in int; it doesn't always, on 64-bit hosts. The new version
14335 doesn't catch all possible integer overflows, but it's an
14336 improvement. (Bug#8719)
14338 * alloc.c (make_event_array): Use XINT, not XUINT.
14339 There's no need for unsigned here.
14341 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
14342 This follows up to the 2011-05-06 change that substituted uintptr_t
14343 for EMACS_INT. This case wasn't caught back then.
14345 Rework Fformat to avoid integer overflow issues.
14346 * editfns.c: Include <float.h> unconditionally, as it's everywhere
14347 now (part of C89). Include <verify.h>.
14348 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
14349 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
14350 (Fformat): Avoid the prepass trying to compute sizes; it was only
14351 approximate and thus did not catch overflow reliably. Instead, walk
14352 through the format just once, formatting and computing sizes as we go,
14353 checking for integer overflow at every step, and allocating a larger
14354 buffer as needed. Keep track separately whether the format is
14355 multibyte. Keep only the most-recently calculated precision, rather
14356 than them all. Record whether each argument has been converted to
14357 string. Use EMACS_INT, not int, for byte and char and arg counts.
14358 Support field widths and precisions larger than INT_MAX. Avoid
14359 sprintf's undefined behavior with conversion specifications such as %#d
14360 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
14361 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
14362 formatting out-of-range floating point numbers with int
14363 formats. (Bug#8668)
14365 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
14367 * data.c: Avoid integer truncation in expressions involving floats.
14368 * data.c: Include <intprops.h>.
14369 (arith_driver): When there's an integer overflow in an expression
14370 involving floating point, convert the integers to floating point
14371 so that the resulting value does not suffer from catastrophic
14372 integer truncation. For example, on a 64-bit host (* 4
14373 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14374 Do not rely on undefined behavior after integer overflow.
14376 merge count_size_as_multibyte, parse_str_to_multibyte
14377 * character.c, character.h (count_size_as_multibyte):
14378 Rename from parse_str_to_multibyte; all uses changed.
14379 Check for integer overflow.
14380 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14381 since it's now a duplicate of the other. This is more of
14382 a character than a buffer op, so better that it's in character.c.
14383 * fns.c, print.c: Adjust to above changes.
14385 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14387 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14389 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14391 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14392 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14393 (x_clipboard_manager_save): Now static.
14394 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14396 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14397 (crypto_hash_function): Now static.
14398 Fix pointer signedness problems. Avoid unnecessary initializations.
14400 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14402 * termhooks.h (Vselection_alist): Make it terminal-local.
14404 * terminal.c (create_terminal): Initialize it.
14406 * xselect.c: Support for clipboard managers.
14407 (Vselection_alist): Move to termhooks.h as terminal-local var.
14408 (LOCAL_SELECTION): New macro.
14409 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14410 (symbol_to_x_atom): Remove gratuitous arg.
14411 (x_handle_selection_request, lisp_data_to_selection_data)
14412 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14413 (x_own_selection, x_get_local_selection, x_convert_selection):
14414 New arg, specifying work frame. Use terminal-local Vselection_alist.
14415 (some_frame_on_display): Delete unused function.
14416 (Fx_own_selection_internal, Fx_get_selection_internal)
14417 (Fx_disown_selection_internal, Fx_selection_owner_p)
14418 (Fx_selection_exists_p): New optional frame arg.
14419 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14420 (x_handle_selection_clear): Don't treat other terminals with the
14421 same keyboard specially. Use the terminal-local Vselection_alist.
14422 (x_clear_frame_selections): Use Frun_hook_with_args.
14424 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14426 * xterm.h: Add support for those atoms.
14428 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14430 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14431 (converted_selections, conversion_fail_tag): New global variables.
14432 (x_selection_request_lisp_error): Free the above.
14433 (x_get_local_selection): Remove unnecessary code.
14434 (x_reply_selection_request): Args changed; handle arbitrary array
14435 of converted selections stored in converted_selections.
14436 Separate the XChangeProperty and SelectionNotify steps.
14437 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14438 (x_convert_selection): New function.
14439 (x_handle_selection_event): Simplify.
14440 (x_get_foreign_selection): Don't ignore incoming requests while
14441 waiting for an answer; this will fail when we implement
14442 SAVE_TARGETS, and seems unnecessary anyway.
14443 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14444 (Vx_sent_selection_functions): Doc fix.
14446 2011-05-26 Leo Liu <sdl.web@gmail.com>
14448 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14450 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14452 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14454 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14455 for fringe update if it has periodic bitmap.
14456 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14457 and fringe_bitmap_periodic_p.
14459 * fringe.c (get_fringe_bitmap_data): New function.
14460 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14461 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14462 row. Mark glyph row for fringe update if periodicity changed.
14464 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14465 for fringe update unless it has periodic bitmap.
14467 2011-05-25 Kenichi Handa <handa@m17n.org>
14469 * xdisp.c (get_next_display_element): Set correct it->face_id for
14470 a static composition.
14472 2011-05-24 Leo Liu <sdl.web@gmail.com>
14475 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
14477 * fns.c (crypto_hash_function, Fsha1): New function.
14478 (Fmd5): Use crypto_hash_function.
14479 (syms_of_fns): Add Ssha1.
14481 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14483 * gnutls.c: Remove unused macros.
14484 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14485 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14486 Remove macros that are defined and never used.
14487 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14489 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14491 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14492 (Fx_get_selection_internal): Minor cleanup.
14493 (Fx_own_selection_internal): Rename arguments for consistency with
14496 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14498 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
14500 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14502 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
14504 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14506 * dispnew.c (scrolling_window): Don't exclude the case that the
14507 last enabled row in the desired matrix touches the bottom boundary.
14509 2011-05-21 Glenn Morris <rgm@gnu.org>
14511 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
14512 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
14513 and add some more files.
14515 2011-05-20 Eli Zaretskii <eliz@gnu.org>
14517 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
14518 report_file_error introduced by the change from 2011-05-07.
14520 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14522 * systime.h (Time): Define only if emacs is defined.
14523 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14524 where the include path doesn't have X11/X.h by default. See
14525 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14527 2011-05-20 Kenichi Handa <handa@m17n.org>
14529 * composite.c (find_automatic_composition): Fix previous change.
14531 2011-05-20 Glenn Morris <rgm@gnu.org>
14533 * lisp.mk: New file, split from Makefile.in.
14534 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14535 (shortlisp): Remove.
14536 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14538 2011-05-19 Glenn Morris <rgm@gnu.org>
14540 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14541 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14542 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14543 (lisp): Set the order to that of loadup.el.
14544 (shortlisp): Make it a copy of $lisp.
14545 (SOME_MACHINE_LISP): Remove.
14546 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14547 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14549 2011-05-18 Kenichi Handa <handa@m17n.org>
14551 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14552 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14553 (find_automatic_composition): Mostly rewrite for efficiency.
14555 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14557 * makefile.w32-in: Update dependencies.
14559 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14561 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14562 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14564 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14566 Fix some integer overflow issues, such as string length overflow.
14568 * insdel.c (count_size_as_multibyte): Check for string overflow.
14570 * character.c (lisp_string_width): Check for string overflow.
14571 Use EMACS_INT, not int, for string indexes and lengths; in
14572 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14573 the resulting string length overflows an EMACS_INT; instead,
14574 report a string overflow if no precision given. When checking for
14575 precision exhaustion, use a check that cannot possibly have
14576 integer overflow. (Bug#8675)
14577 * character.h (lisp_string_width): Adjust to new signature.
14579 * alloc.c (string_overflow): New function.
14580 (Fmake_string): Use it. This doesn't change behavior, but saves
14581 a few bytes and will simplify future changes.
14582 * character.c (string_escape_byte8): Likewise.
14583 * lisp.h (string_overflow): New decl.
14585 Fixups, following up to the user-interface timestamp change.
14586 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14587 for UI timestamps, instead of unsigned long.
14588 * msdos.c (mouse_get_pos): Likewise.
14589 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14590 * w32gui.h (Time): Define by including "systime.h" rather than by
14591 declaring it ourselves. (Bug#8664)
14593 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14594 * image.c (clear_image_cache): Likewise.
14596 * term.c (term_mouse_position): Don't assume time_t wraparound.
14598 Be more systematic about user-interface timestamps.
14599 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14600 and sometimes 'EMACS_UINT', to represent these timestamps.
14601 This change causes it to use 'Time' uniformly, as that's what X uses.
14602 This makes the code easier to follow, and makes it easier to catch
14603 integer overflow bugs such as Bug#8664.
14604 * frame.c (Fmouse_position, Fmouse_pixel_position):
14605 Use Time, not unsigned long, for user-interface timestamps.
14606 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14607 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14608 * keyboard.h (last_event_timestamp): Likewise.
14609 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14610 * menu.h (xmenu_show): Likewise.
14611 * term.c (term_mouse_position): Likewise.
14612 * termhooks.h (struct input_event.timestamp): Likewise.
14613 (struct terminal.mouse_position_hook): Likewise.
14614 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14615 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14616 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14617 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14618 what it was before.
14619 * menu.h, termhooks.h: Include "systime.h", for Time.
14621 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14622 Don't assume that the difference between two unsigned long values
14623 can fit into an integer. At this point, we know button_down_time
14624 <= event->timestamp, so the difference must be nonnegative, so
14625 there's no need to cast the result if double-click-time is
14626 nonnegative, as it should be; check that it's nonnegative, just in
14627 case. This bug is triggered when events are more than 2**31 ms
14628 apart (about 25 days). (Bug#8664)
14630 * xselect.c (last_event_timestamp): Remove duplicate decl.
14631 (x_own_selection): Remove needless cast to unsigned long.
14633 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14634 that always fit in int. Use a sentinel instead of a counter, to
14635 avoid a temp and to allay GCC's concerns about possible int overflow.
14636 * frame.h (struct frame): Use int for menu_bar_items_used
14637 instead of EMACS_INT, since it always fits in int.
14639 * menu.c (grow_menu_items): Check for int overflow.
14641 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14643 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14644 Before, the code was not consistent. These values cannot exceed
14645 2**31 - 1 so there's no need to make them unsigned.
14646 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14647 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14648 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14650 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14652 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14653 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14654 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14655 presumably because the widths might not match.
14657 * window.c (size_window): Avoid needless test at loop start.
14659 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14661 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14663 2011-05-12 Drew Adams <drew.adams@oracle.com>
14665 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14667 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14669 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14670 `width' to `bar_area_x' and `bar_area_width', respectively.
14671 (x_scroll_run): Take account of fringe background extension.
14673 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14674 Rename local vars `left' and `width' to `bar_area_x' and
14675 `bar_area_width', respectively.
14676 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14677 background extension.
14679 2011-05-10 Jim Meyering <meyering@redhat.com>
14681 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14683 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14685 * image.c (Finit_image_library): Return t for built-in image types,
14686 like pbm and xbm. (Bug#8640)
14688 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14690 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14692 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14694 * w32console.c (Fset_screen_color): Doc fix.
14695 (Fget_screen_color): New function.
14696 (syms_of_ntterm): Defsubr it.
14698 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14699 unlink the temporary file if Fcall_process didn't create it in the
14701 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14702 child process will be redirected to a file specified with `:file'.
14703 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14704 cue to call_process_cleanup not to close that handle.
14706 2011-05-07 Ben Key <bkey76@gmail.com>
14708 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14709 one of two shell specific rules, either bootstrap-temacs-CMD or
14710 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14711 to the previous implementation of the bootstrap-temacs rule.
14712 The bootstrap-temacs-CMD rule is similar to the previous
14713 implementation of the bootstrap-temacs rule except that it
14714 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14717 These changes, along with some changes to nt/configure.bat,
14718 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14719 earlier fix to add support for --cflags and --ldflags options
14720 that include quotes so that it works whether make uses cmd or
14723 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14725 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14726 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14728 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14729 a string. Handle both cases.
14730 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14731 (Fdbus_register_method): Use Qinvalid_function.
14733 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14735 * makefile.w32-in: Update dependencies.
14736 (LISP_H): Add inttypes.h and stdin.h.
14737 (PROCESS_H): Add unistd.h.
14739 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14741 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14742 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14744 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14746 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14748 * term.c (vfatal): Remove stray call to va_end.
14749 It's not needed and the C Standard doesn't allow it here anyway.
14751 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14752 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14754 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14757 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14759 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14761 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14763 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14765 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14767 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14768 * charset.c (Fdefine_charset_internal): Don't initialize
14769 charset.code_space[15]. The value was garbage, on hosts with
14770 32-bit int (Bug#8600).
14772 * lread.c (read_integer): Be more consistent with string-to-number.
14773 Use string_to_number to do the actual conversion; this avoids
14774 rounding errors and fixes some other screwups. Without this fix,
14775 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14776 (digit_to_number): Move earlier, for benefit of read_integer.
14777 Return -1 if the digit is out of range for the base, -2 if it is
14778 not a digit in any supported base. (Bug#8602)
14780 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14782 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14783 to match comment at start of function. This also removes a
14784 GCC warning about overflow in a 32+64-bit port.
14786 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14788 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14789 Reported by Stefan Monnier in
14790 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14791 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14792 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14794 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14795 (EMACS_UINTPTR): Likewise, with uintptr_t.
14797 * lisp.h: Prefer 64-bit EMACS_INT if available.
14798 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14799 on 32-bit hosts that have 64-bit int, so that they can access
14801 However, temporarily disable this change unless the temporary
14802 symbol WIDE_EMACS_INT is defined.
14804 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14806 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14807 This removes an assumption that EMACS_INT and long are the same
14808 width as pointers. The assumption is true for Emacs porting targets
14809 now, but we want to make other targets possible.
14810 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14811 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14812 In the rest of the code, change types of integers that hold casted
14813 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14814 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14815 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14816 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14817 No need to cast type when ORing.
14818 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14819 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14820 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14821 assume EMACS_INT is the same width as char *.
14822 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14823 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14824 Remove no-longer-needed casts.
14825 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14826 (xg_tool_bar_help_callback, xg_make_tool_item):
14827 Use EMACS_INTPTR to hold an integer
14828 that will be cast to void *; this can avoid a GCC warning
14829 if EMACS_INT is not the same width as void *.
14830 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14831 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14832 (current_message_1, set_message_1):
14833 Use a local to convert to proper width without a cast.
14834 * xmenu.c (dialog_selection_callback): Likewise.
14836 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14837 Also, don't assume VALBITS / RAND_BITS is less than 5,
14838 and don't rely on undefined behavior when shifting a 1 left into
14840 * lisp.h (get_random): Change signature to match.
14842 * lread.c (hash_string): Use size_t, not int, for hash computation.
14843 Normally we prefer signed values; but hashing is special, because
14844 it's better to use unsigned division on hash table sizes so that
14845 the remainder is nonnegative. Also, size_t is the natural width
14846 for hashing into memory. The previous code used 'int', which doesn't
14847 retain enough info to hash well into very large tables.
14848 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14850 * dbusbind.c: Don't possibly lose pointer info when converting.
14851 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14852 Use XPNTR rather than XHASH, so that the high-order bits of
14853 the pointer aren't lost when converting through void *.
14855 * eval.c (Fautoload): Don't double-shift a pointer.
14857 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14859 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14861 * gnutls.c (DEF_GNUTLS_FN):
14862 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14864 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14866 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14869 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14871 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14872 New version that can reserve upto 2GB of heap space.
14874 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14876 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14878 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14880 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14881 `gnutls_certificate_set_x509_key_file'.
14883 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
14885 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
14886 Update dependencies.
14888 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14890 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14891 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14892 Remove unused parameter `fildes'.
14893 * process.c (read_process_output, send_process): Don't pass it.
14895 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14897 Fix previous change: the library cache is defined in w32.c.
14898 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14899 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14901 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14903 Implement dynamic loading of GnuTLS on Windows.
14905 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14906 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14907 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14910 * gnutls.c (Qgnutls_dll): Define.
14911 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
14912 (gnutls_*): Declare function pointers.
14913 (init_gnutls_functions): New function to initialize function pointers.

14916 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14917 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
14918 (emacs_gnutls_write, emacs_gnutls_read)
14919 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14920 (Fgnutls_available_p): New function.
14921 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

14933 * w32.c (QCloaded_from, Vlibrary_cache): Define.
14934 (w32_delayed_load): Move from image.c. When loading a library, record
14935 its filename in the :loaded-from property of the library id.
14936 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
14937 Initialize and staticpro them.
14938 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
14940 * process.c: Include lisp.h before w32.h, not after.
14941 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
14942 instead of gnutls_record_check_pending.
14944 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
14946 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
14948 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
14949 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
14952 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
14954 * xterm.c (x_set_frame_alpha): Do not set property on anything
14955 else than FRAME_X_OUTER_WINDOW (Bug#8608).

14959 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
14961 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14963 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

14977 * sysdep.c (wait_for_termination_1): Make static.
14978 (wait_for_termination, interruptible_wait_for_termination):
14979 Move after wait_for_termination_1.
14981 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
14983 * sysdep.c (interruptible_wait_for_termination): New function
14984 which is like wait_for_termination, but allows keyboard
14987 * callproc.c (Fcall_process): Add (:file "file") as an option for
14989 (Fcall_process_region): Ditto.
14991 2011-04-30 Eli Zaretskii <eliz@gnu.org>
14993 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
14994 rather than `XVECTOR (FOO)->size'.
14996 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
14997 inttypes.h, as a gnulib replacement is used if it not available in
15000 2011-04-21 Eli Zaretskii <eliz@gnu.org>
15002 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
15003 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
15004 of MOST_POSITIVE_FIXNUM. (Bug#8528)
15006 * coding.c (coding_alloc_by_realloc): Error out if destination
15007 will grow beyond MOST_POSITIVE_FIXNUM.
15008 (decode_coding_emacs_mule): Abort if there isn't enough place in
15009 charbuf for the composition carryover bytes. Reserve an extra
15010 space for up to 2 characters produced in a loop.
15011 (decode_coding_iso_2022): Abort if there isn't enough place in
15012 charbuf for the composition carryover bytes.

15019 %llo or %llx format is passed. (Bug#8545)
15021 * window.c (window_scroll_line_based): Use a marker instead of
15022 simple variables to record original value of point. (Bug#7952)
15024 * doprnt.c (doprnt): Fix the case where a multibyte sequence
15025 produced by %s or %c overflows available buffer space. (Bug#8545)
15027 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
15029 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

15062 2011-04-27 Eli Zaretskii <eliz@gnu.org>
15064 Improve `doprnt' and its usage. (Bug#8545)
15065 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
15066 `format_end'. Remove support for %l as a conversion specifier.
15067 Don't use xrealloc. Improve diagnostics when the %l size modifier
15068 is used. Update the commentary.
15070 * eval.c (verror): Simplify calculation of size_t.
15072 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
15075 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
15077 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
15080 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15082 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
15083 This makes this file independent of the recent pseudovector change.
15085 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
15087 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
15089 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
15090 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
15091 Remove unused local.
15092 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
15094 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
15095 GCC 4.6.0 optimizes based on type-based alias analysis.
15096 For example, if b is of type struct buffer * and v of type struct
15097 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
15098 != &v->size, and therefore "v->size = 1; b->size = 2; return
15099 v->size;" must therefore return 1. This assumption is incorrect
15100 for Emacs, since it type-puns struct Lisp_Vector * with many other
15101 types. To fix this problem, this patch adds a new type struct
15102 vectorlike_header that documents the constraints on layout of vectors
15103 and pseudovectors, and helps optimizing compilers not get fooled
15104 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
15105 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
15106 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
15108 (XSETPVECTYPE): Rewrite in terms of new macro.
15109 (XSETPVECTYPESIZE): New macro, specifying both type and size.
15110 This is a bit clearer, and further avoids the possibility of
15111 undesirable aliasing.
15112 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
15113 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
15114 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
15115 since Lisp_Subr is a special case (no "next" field).
15116 (ASIZE): Now uses header.size rather than size.
15117 All previous uses of XVECTOR (foo)->size replaced to use this macro,
15118 to avoid the hassle of writing XVECTOR (foo)->header.size.
15119 (struct vectorlike_header): New type.
15120 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
15121 object, to help avoid aliasing.
15122 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
15123 (SUBRP): Likewise, since Lisp_Subr is a special case.
15124 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
15125 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
15126 (struct Lisp_Hash_Table): Combine first two members into a single
15127 struct vectorlike_header member. All uses of "size" and "next" members
15128 changed to be "header.size" and "header.next".
15129 * buffer.h (struct buffer): Likewise.
15130 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
15131 * frame.h (struct frame): Likewise.
15132 * process.h (struct Lisp_Process): Likewise.
15133 * termhooks.h (struct terminal): Likewise.
15134 * window.c (struct save_window_data, struct saved_window): Likewise.
15135 * window.h (struct window): Likewise.
15136 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
15137 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
15138 * buffer.c (init_buffer_once): Likewise.
15139 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
15141 * process.c (Fformat_network_address): Use local var for size,
15144 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
15146 Make the Lisp reader and string-to-float more consistent (Bug#8525)
15147 * data.c (atof): Remove decl; no longer used or needed.
15148 (digit_to_number): Move to lread.c.
15149 (Fstring_to_number): Use new string_to_number function, to be
15150 consistent with how the Lisp reader treats infinities and NaNs.
15151 Do not assume that floating-point numbers represent EMACS_INT
15152 without losing information; this is not true on most 64-bit hosts.
15153 Avoid double-rounding errors, by insisting on integers when
15154 parsing non-base-10 numbers, as the documentation specifies.
15155 * lisp.h (string_to_number): New decl, replacing ...
15156 (isfloat_string): Remove.
15157 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
15158 (read1): Do not accept +. and -. as integers; this
15159 appears to have been a coding error. Similarly, do not accept
15160 strings like +-1e0 as floating point numbers. Do not report
15161 overflow for integer overflows unless the base is not 10 which
15162 means we have no simple and reliable way to continue.
15163 Break out the floating-point parsing into a new
15164 function string_to_number, so that Fstring_to_number parses
15165 floating point numbers consistently with the Lisp reader.
15166 (digit_to_number): Move here from data.c. Make it static inline.
15167 (E_CHAR, EXP_INT): Remove, replacing with ...
15168 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
15169 (string_to_number): New function, replacing isfloat_string.
15170 This function checks for valid syntax and produces the resulting
15171 Lisp float number too. Rework it so that string-to-number
15172 no longer mishandles examples like "1.0e+". Use strtoumax,
15173 so that overflow for non-base-10 numbers is reported only when
15174 there's no portable and simple way to convert to floating point.
15176 * textprop.c (set_text_properties_1): Rewrite for clarity,
15177 and to avoid GCC warning about integer overflow.
15179 * intervals.h (struct interval): Use EMACS_INT for members
15180 where EMACS_UINT might cause problems. See
15181 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
15182 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
15183 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
15185 (offset_intervals): Tell GCC not to worry about length overflow
15186 when negating a negative length.
15188 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
15189 (overrun_check_free): Likewise.
15191 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
15192 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
15195 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15196 (gnutls_make_error): Rename local to avoid shadowing.
15197 (gnutls_emacs_global_deinit): ifdef out; not used.
15198 (Fgnutls_boot): Use const for pointer to readonly storage.
15199 Comment out unused local. Fix pointer signedness problems.
15201 * lread.c (openp): Don't stuff size_t into an 'int'.
15202 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
15203 about possible signed overflow.
15205 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15206 (GDK_KEY_g): Don't define if already defined.
15207 (xg_prepare_tooltip): Avoid pointer signedness problem.
15208 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
15210 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
15211 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
15213 * xfns.c (Fx_window_property): Simplify a bit,
15214 to make a bit faster and to avoid GCC 4.6.0 warning.
15215 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
15217 * fns.c (internal_equal): Don't assume size_t fits in int.
15219 * alloc.c (compact_small_strings): Tighten assertion a little.
15221 Replace pEd with more-general pI, and fix some printf arg casts.
15222 * lisp.h (pI): New macro, generalizing old pEd macro to other
15223 conversion specifiers. For example, use "...%"pI"d..." rather
15224 than "...%"pEd"...".
15225 (pEd): Remove. All uses replaced with similar uses of pI.
15226 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
15227 * alloc.c (check_pure_size): Don't overflow by converting size to int.
15228 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
15229 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
15230 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
15231 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
15232 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
15234 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
15235 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
15236 * print.c (safe_debug_print, print_object): Likewise.
15237 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
15239 Use pI instead of if-then-else-abort. Use %p to avoid casts,
15240 avoiding the 0 flag, which is not portable.
15241 * process.c (Fmake_network_process): Use pI to avoid cast.
15242 * region-cache.c (pp_cache): Likewise.
15243 * xdisp.c (decode_mode_spec): Likewise.
15244 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
15245 behavior on 64-bit hosts with printf arg.
15246 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
15247 (x_stop_queuing_selection_requests): Likewise.
15248 (x_get_window_property): Don't truncate byte count to an 'int'
15251 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
15252 here, since it parses constructs like leading '-' and spaces,
15253 which are not wanted; and it overflows with large numbers.
15254 Instead, simply match F[0-9]+, which is what is wanted anyway.
15256 * alloc.c: Remove unportable assumptions about struct layout.
15257 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
15258 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
15259 (allocate_vectorlike, make_pure_vector): Use the new macros,
15260 plus offsetof, to remove unportable assumptions about struct layout.
15261 These assumptions hold on all porting targets that I know of, but
15262 they are not guaranteed, they're easy to remove, and removing them
15263 makes further changes easier.
15265 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
15266 This doesn't fix a bug but makes the code clearer.
15267 (string_overrun_cookie): Now const. Use initializers that
15268 don't formally overflow signed char, to avoid warnings.
15269 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
15270 can cause Emacs to crash when string overrun checking is enabled.
15271 (allocate_buffer): Don't assume sizeof (struct buffer) is a
15272 multiple of sizeof (EMACS_INT); it need not be, if
15273 alignof(EMACS_INT) < sizeof (EMACS_INT).
15274 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
15276 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

15283 supposed to be handshaking. (Bug#8556)
15284 Reported by Paul Eggert <eggert@cs.ucla.edu>.
15286 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

15292 matches the current signal symbol.
15294 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
15296 * alloc.c (check_sblock, check_string_bytes)
15297 (check_string_free_list): Convert to standard C.
15299 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
15301 * w32.c (emacs_gnutls_push): Fix typo.
15303 2011-04-25 Eli Zaretskii <eliz@gnu.org>
15305 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
15306 "cast to pointer from integer of different size".
15308 Improve doprnt and its use in verror. (Bug#8545)
15309 * doprnt.c (doprnt): Document the set of format control sequences
15310 supported by the function. Use SAFE_ALLOCA instead of always
15313 * eval.c (verror): Don't limit the buffer size at size_max-1, that
15314 is one byte too soon. Don't use xrealloc; instead xfree and
15317 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
15319 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
15322 * gnutls.c: Renamed global_initialized to
15323 gnutls_global_initialized. Added internals for the
15324 :verify-hostname-error, :verify-error, and :verify-flags
15325 parameters of `gnutls-boot' and documented those parameters in the
15326 docstring. Start callback support.
15327 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
15328 unless a fatal error occurred. Call gnutls_alert_send_appropriate
15329 on error. Return error code.

15402 (SIZE_MAX): New macro.
15403 (doprnt): Return a size_t value. 2nd arg is now size_t.
15404 Many local variables are now size_t instead of int or unsigned.
15405 Improve overflow protection. Support `l' modifier for integer
15406 conversions. Support %l conversion. Don't assume an EMACS_INT
15407 argument for integer conversions and for %c.
15409 * lisp.h (doprnt): Restore prototype.
15411 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
15412 $(SRC)/character.h.
15414 * Makefile.in (base_obj): Add back doprnt.o.
15416 * deps.mk (doprnt.o): Add back prerequisites.
15417 (callint.o): Depend on character.h.
15419 * eval.c (internal_lisp_condition_case): Include the handler
15420 representation in the error message.

15426 * callint.c (Fcall_interactively): When displaying error message
15427 about invalid control letter, pass the character's codepoint, not
15428 a pointer to its multibyte form. Improve display of the character
15429 in octal and display also its hex code.
15431 * character.c (char_string): Use %x to display the (unsigned)
15432 codepoint of an invalid character, to avoid displaying a bogus
15435 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15436 `error', not SYMBOL_NAME itself.
15438 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
15439 character arguments to `error'.
15441 * charset.c (check_iso_charset_parameter): Fix incorrect argument
15442 to `error' in error message about FINAL_CHAR argument. Make sure
15443 FINAL_CHAR is a character, and use %c when it is passed as

15508 Define only if needed.
15510 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
15511 by pacifying GCC about it. Maybe it's time to retire it?
15512 * xfaces.c (USG, __TIMEVAL__): Likewise.
15514 * dispextern.h (struct redisplay_interface): Rename param
15515 to avoid shadowing.
15516 * termhooks.h (struct terminal): Likewise.
15517 * xterm.c (xembed_send_message): Likewise.
15519 * insdel.c (make_gap_smaller): Define only if
15520 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
15522 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
15525 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
15526 so that we aren't warned about unused symbols.
15528 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
15530 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

15539 define if USE_GTK || USE_X_TOOLKIT.
15540 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
15541 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.

15543 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
15545 * xmenu.c (menu_help_callback): Pointer type fixes.

15563 compatible char. Avoid the old compiler warnings about
15564 out-of-range initializers by using, for example, '\xab' rather
15567 * xgselect.c (xgselect_initialize): Check vs interface
15568 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

15633 * nsfont.m: Fixed bugs in ns_get_family and
15634 ns_descriptor_to_entity that were caused by using free to
15635 deallocate memory blocks that were allocated by xmalloc (via
15636 xstrdup). This caused Emacs to crash when compiled with
15637 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
15638 --enable-checking=xmallocoverrun). xfree is now used to
15639 deallocate these memory blocks.

16038 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
16039 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
16040 Remove decls of unexported vars.
16041 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
16043 * lisp.h (DEFINE_FUNC): Make sname 'static'.
16045 Make Emacs functions such as Fatom 'static' by default.
16046 This makes it easier for human readers (and static analyzers)
16047 to see whether these functions can be called from other modules.
16048 DEFUN now defines a static function. To make the function external
16049 so that it can be used in other C modules, use the new macro DEFUE.
16050 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
16051 (Finit_image_library):
16052 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
16053 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
16054 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
16055 Remove decls, since these functions are now static.
16056 (Funintern, Fget_internal_run_time): New decls, since these functions
16057 were already external.
16059 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
16060 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
16061 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
16062 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
16063 * keyboard.c, keymap.c, lread.c:
16064 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
16065 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
16066 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
16067 Mark functions with DEFUE instead of DEFUN,
16068 if they are used in other modules.
16069 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
16070 decls for now-static functions.
16071 * buffer.h (Fdelete_overlay): Remove decl.
16072 * callproc.c (Fgetenv_internal): Mark as internal.
16073 * composite.c (Fremove_list_of_text_properties): Remove decl.
16074 (Fcomposition_get_gstring): New forward static decl.
16075 * composite.h (Fcomposite_get_gstring): Remove decl.
16076 * dired.c (Ffile_attributes): New forward static decl.
16077 * doc.c (Fdocumntation_property): New forward static decl.
16078 * eval.c (Ffetch_bytecode): New forward static decl.
16079 (Funintern): Remove extern decl; now in .h file where it belongs.
16080 * fileio.c (Fmake_symbolic_link): New forward static decl.
16081 * image.c (Finit_image_library): New forward static decl.
16082 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
16083 * intervals.h (Fprevious_property_change):
16084 (Fremove_list_of_text_properties): Remove decls.
16085 * keyboard.c (Fthis_command_keys): Remove decl.
16086 (Fcommand_execute): New forward static decl.
16087 * keymap.c (Flookup_key): New forward static decl.
16088 (Fcopy_keymap): Now static.
16089 * keymap.h (Flookup_key): Remove decl.
16090 * process.c (Fget_process): New forward static decl.
16091 (Fprocess_datagram_address): Mark as internal.
16092 * syntax.c (Fsyntax_table_p): New forward static decl.
16093 (skip_chars): Remove duplicate decl.
16094 * textprop.c (Fprevious_property_change): New forward static decl.
16095 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
16097 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
16098 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
16100 * editfns.c (Fformat): Remove unreachable code.
16102 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
16104 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
16107 2011-04-13 Eli Zaretskii <eliz@gnu.org>
16109 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
16110 when at ZV. (Bug#8487)
16112 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
16114 * charset.c (Fclear_charset_maps): Use xfree instead of free.
16116 * keyboard.c (parse_tool_bar_item): Likewise.
16117 * sound.c (sound_cleanup, alsa_close): Likewise.
16118 * termcap.c (tgetent): Likewise.
16119 * xfns.c (x_default_font_parameter): Likewise.
16120 * xsettings.c (read_and_apply_settings): Likewise.
16122 * alloc.c (overrun_check_malloc, overrun_check_realloc)
16123 (overrun_check_free): Protoize.
16125 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
16127 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
16128 since callers should never pass a negative size.
16129 Change the signature to match that of plain 'read' and 'write'; see
16130 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
16131 * lisp.h: Update prototypes of emacs_write and emacs_read.
16133 2011-04-11 Eli Zaretskii <eliz@gnu.org>
16135 * xdisp.c (redisplay_window): Don't try to determine the character
16136 position of the scroll margin if the window start point w->startp
16137 is outside the buffer's accessible region. (Bug#8468)
16139 2011-04-10 Eli Zaretskii <eliz@gnu.org>
16141 Fix write-region and its subroutines for buffers > 2GB.
16142 * fileio.c (a_write, e_write): Modify declaration of arguments and
16143 local variables to support buffers larger than 2GB.
16144 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
16146 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
16147 argument, local variables, and return value.
16149 * lisp.h: Update prototypes of emacs_write and emacs_read.
16151 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
16153 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
16155 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
16157 Fix more problems found by GCC 4.6.0's static checks.
16159 * xdisp.c (vmessage): Use a better test for character truncation.
16161 * charset.c (load_charset_map): <, not <=, for optimization,
16162 and to avoid potential problems with integer overflow.
16163 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
16164 * casetab.c (set_identity, shuffle): Likewise.
16165 * editfns.c (Fformat): Likewise.
16166 * syntax.c (skip_chars): Likewise.
16168 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
16169 This also lets GCC 4.6.0 generate slightly better loop code.
16171 * callint.c (Fcall_interactively): <, not <=, for optimization.
16172 (Fcall_interactively): Count the number of arguments produced,
16173 not the number of arguments given. This is simpler and lets GCC
16174 4.6.0 generate slightly better code.
16176 * ftfont.c: Distingish more carefully between FcChar8 and char.
16177 The previous code passed unsigned char * to a functions like
16178 strlen and xstrcasecmp that expect char *, which does not
16179 conform to the C standard.
16180 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
16181 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
16182 char * when the C standard requires it.
16184 * keyboard.c (read_char): Remove unused var.
16186 * eval.c: Port to Windows vsnprintf (Bug#8435).
16187 Include <limits.h>.
16188 (SIZE_MAX): Define if the headers do not.
16189 (verror): Do not give up if vsnprintf returns a negative count.
16190 Instead, grow the buffer. This ports to Windows vsnprintf, which
16191 does not conform to C99. Problem reported by Eli Zaretskii.
16192 Also, simplify the allocation scheme, by avoiding the need for
16193 calling realloc, and removing the ALLOCATED variable.
16195 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
16197 Remove invocations of doprnt, as Emacs now uses vsnprintf.
16198 But keep the doprint source code for now, as we might revamp it
16199 and use it again (Bug#8435).
16200 * lisp.h (doprnt): Remove.
16201 * Makefile.in (base_obj): Remove doprnt.o.
16202 * deps.mk (doprnt.o): Remove.
16204 error: Print 32- and 64-bit integers portably (Bug#8435).
16205 Without this change, on typical 64-bit hosts error ("...%d...", N)
16206 was used to print both 32- and 64-bit integers N, which relied on
16207 undefined behavior.
16208 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
16209 * lisp.h (error, verror): Mark as printf-like functions.
16210 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
16211 Report overflow in size calculations when allocating printf buffer.
16212 Do not truncate output string at its first null byte.
16213 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
16214 Truncate the output at a character boundary, since vsnprintf does not
16216 * charset.c (check_iso_charset_parameter): Convert internal
16217 character to string before calling 'error', since %c now has the
16219 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
16220 overflow when computing char to be passed to 'error'. Do not
16221 pass Lisp_Object to 'error'; pass the integer instead.
16222 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
16223 formatted with plain %d.
16225 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
16227 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
16229 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
16231 * xterm.c (x_catch_errors): Remove duplicate declaration.
16233 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
16235 * xdisp.c, lisp.h (message_nolog): Remove; unused.
16237 2011-04-10 Jim Meyering <meyering@redhat.com>
16239 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
16240 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
16241 return ssize_t not "int", and use size_t as the buffer length.
16242 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
16243 * gnutls.h: Update declarations.
16244 * process.c (read_process_output): Use ssize_t, to match.
16245 (send_process): Likewise.
16247 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16249 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
16251 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16253 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
16254 Use unsigned char, to match FcChar8 type definition.
16256 * xterm.c (handle_one_xevent):
16257 * xmenu.c (create_and_show_popup_menu):
16258 * xselect.c (x_decline_selection_request)
16259 (x_reply_selection_request): Avoid type-punned deref of X events.
16261 2011-04-09 Eli Zaretskii <eliz@gnu.org>
16263 Fix some uses of `int' instead of EMACS_INT.
16264 * search.c (string_match_1, fast_string_match)
16265 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
16266 (scan_buffer, find_next_newline_no_quit)
16267 (find_before_next_newline, search_command, Freplace_match)
16268 (Fmatch_data): Make some `int' variables be EMACS_INT.
16270 * xdisp.c (display_count_lines): 3rd argument and return value now
16271 EMACS_INT. All callers changed.
16272 (pint2hrstr): Last argument is now EMACS_INT.
16274 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
16275 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
16276 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
16277 (decode_coding_utf_16, decode_coding_emacs_mule)
16278 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
16279 (decode_coding_ccl, decode_coding_charset)
16280 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
16281 (decode_coding_iso_2022, decode_coding_emacs_mule)
16282 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
16283 <char_offset, last_offset>: Declare EMACS_INT.

16286 (encode_designation_at_bol, encode_coding_iso_2022)
16287 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
16288 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
16290 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
16291 (encode_invocation_designation): Last argument P_NCHARS is now
16293 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
16294 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
16296 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
16299 * ccl.c (Fccl_execute_on_string): Declare some variables
16302 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
16304 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
16306 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
16308 * process.c (Fformat_network_address): Doc fix.
16310 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
16312 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
16314 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
16316 * keyboard.c (read_char): Call Lisp function help-form-show,
16317 instead of using internal_with_output_to_temp_buffer.
16318 (Qhelp_form_show): New var.
16319 (syms_of_keyboard): Use DEFSYM macro.
16321 * print.c (internal_with_output_to_temp_buffer): Function deleted.

16332 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
16334 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
16336 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
16338 Fix more problems found by GCC 4.6.0's static checks.

16344 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
16346 * xdisp.c (vmessage): Mark as a printf-like function.
16348 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
16350 * sound.c (sound_warning): Don't crash if arg contains a printf format.

16355 to system-supplied API.
16357 * eval.c (Fsignal): Remove excess argument to 'fatal'.
16359 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
16360 This avoids several warnings with gcc -Wstrict-overflow.
16361 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
16362 directly, rather than having caller test rule sign. This avoids
16363 some unnecessary tests.
16364 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
16365 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
16366 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
16368 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16369 (xfont_open): Avoid unnecessary tests.
16371 * composite.c (composition_gstring_put_cache): Use unsigned integer.

16380 by using the new macro.
16382 * textprop.c (set_text_properties_1): Change while to do-while,
16383 since the condition is always true at first.
16385 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16386 (interval_deletion_adjustment): Return unsigned value.
16389 * process.c (list_processes_1, create_pty, read_process_output):

16405 * print.c (print_error_message): Avoid int overflow.
16407 * font.c (font_list_entities): Redo for clarity,
16408 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
16410 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
16411 (font_score): Avoid potential overflow in diff calculation.
16413 * fns.c (substring_both): Remove var that is set but not used.
16414 (sxhash): Redo loop for clarity and to avoid wraparound warning.
16416 * eval.c (funcall_lambda): Rename local to avoid shadowing.
16418 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
16419 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
16420 can always succeed if overflow has undefined behavior.
16422 * search.c (boyer_moore, wordify): Remove vars set but not used.
16423 (wordify): Omit three unnecessary tests.
16425 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
16426 All callers changed. This avoids the need for an unused var.
16428 * casefiddle.c (casify_region): Remove var that is set but not used.
16430 * dired.c (file_name_completion): Remove var that is set but not used.

16434 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16435 (Finsert_file_contents): Remove unnecessary code checking fd.
16437 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
16438 Check for integer overflow on size calculations.
16440 * buffer.c (Fprevious_overlay_change): Remove var that is set
16443 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16444 Remove vars that are set but not used.
16445 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16446 (timer_check_2): Mark vars as initialized.
16448 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16450 * image.c (lookup_image): Remove var that is set but not used.
16451 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16453 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16454 that are set but not used.
16456 * xfns.c (make_invisible_cursor): Don't return garbage
16457 if XCreateBitmapFromData fails (Bug#8410).
16459 * xselect.c (x_get_local_selection, x_handle_property_notify):
16460 Remove vars that are set but not used.
16462 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

16468 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16469 Check for overflow.
16471 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16472 (map_tty_color) [!defined MSDOS]: Likewise.
16474 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16476 * coding.c: Remove vars that are set but not used.
16477 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
16478 All callers changed.
16479 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):

16486 * print.c (print_object): Remove var that is set but not used.
16488 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16489 The gnulib version avoids calling malloc in the usual case,
16490 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16491 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16492 * filelock.c (current_lock_owner): Likewise.
16493 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16494 * sysdep.c: Include allocator.h, careadlinkat.h.
16495 (emacs_no_realloc_allocator): New static constant.
16496 (emacs_readlink): New function.
16497 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16498 ../lib/careadlinkat.h.
16500 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
16502 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

16524 do not dereference NULL upon failed strdup
16525 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16526 (ns_get_family): Likewise.
16528 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16530 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16532 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16534 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16537 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16539 Add lexical binding.
16541 * window.c (Ftemp_output_buffer_show): New fun.

16550 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16552 (syms_of_lread): Declare `lexical-binding'.
16554 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16556 * keyboard.c (eval_dyn): New fun.
16557 (menu_item_eval_property): Use it.
16559 * image.c (parse_image_spec): Use Ffunctionp.
16561 * fns.c (concat, mapcar1): Accept byte-code-functions.
16563 * eval.c (Fsetq): Handle lexical vars.
16564 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16565 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16566 (FletX, Flet): Obey lexical binding.
16567 (Fcommandp): Handle closures.
16568 (Feval): New `lexical' arg.
16569 (eval_sub): New function extracted from Feval. Use it almost
16570 everywhere where Feval was used. Look up vars in lexical env.
16572 (Ffunctionp): Move from subr.el.
16573 (Ffuncall): Handle closures.
16574 (apply_lambda): Remove `eval_flags'.
16575 (funcall_lambda): Handle closures and new byte-code-functions.
16576 (Fspecial_variable_p): New function.
16577 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16578 but without exporting it to Lisp.
16580 * doc.c (Fdocumentation, store_function_docstring):
16581 * data.c (Finteractive_form): Handle closures.
16583 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16586 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16588 (exec_byte_code): New function extracted from Fbyte_code to handle new
16589 calling convention for byte-code-functions. Add new byte-codes.
16591 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

16597 * xdisp.c (redisplay_internal): Fix prototype.
16599 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16601 * xdisp.c (SCROLL_LIMIT): New macro.
16602 (try_scrolling): Use it when setting scroll_limit.
16603 Limit scrolling to 100 screen lines.
16604 (redisplay_window): Even when falling back on "recentering",
16605 position point in the window according to scroll-conservatively,
16606 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16608 (try_scrolling): When point is above the window, allow searching
16609 as far as scroll_max, or one screenful, to compute vertical
16610 distance from PT to the scroll margin position. This prevents
16611 try_scrolling from unnecessarily failing when
16612 scroll-conservatively is set to a value slightly larger than the
16613 window height. Clean up the case of PT below the margin at bottom
16614 of window: scroll_max can no longer be INT_MAX. When aggressive
16615 scrolling is in use, don't let point enter the opposite scroll
16616 margin as result of the scroll.
16617 (syms_of_xdisp) <scroll-conservatively>: Document the
16618 threshold of 100 lines for never-recentering scrolling.

16625 (message_log_check_duplicate): Remove parameters `prev_bol' and
16626 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16627 (redisplay_internal): Remove parameter `preserve_echo_area',
16628 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16630 * indent.c (Fvertical_motion):
16631 * window.c (window_scroll_pixel_based, Frecenter):
16632 Don't pass `need_y_p' to `move_it_by_lines'.
16634 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16636 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16637 steal a few bits to be more compact.
16638 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16639 Remove unneeded casts.
16641 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16643 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16645 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16646 binding" message (bug#7967).
16648 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16650 Fix more problems found by GCC 4.6.0's static checks.
16652 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16653 Remove unused local var.
16655 * editfns.c (Fmessage_box): Remove unused local var.
16657 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16658 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16659 Omit unused local vars.
16660 * window.c (shrink_windows): Omit unused local var.
16661 * menu.c (digest_single_submenu): Omit unused local var.
16662 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16663 Omit unused local var.
16665 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16666 Don't assume string length fits in int.
16667 (keyremap_step, read_key_sequence): Use size_t for sizes.
16668 (read_key_sequence): Don't check last_real_key_start redundantly.
16670 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
16671 instead of alloca (Bug#8344).
16673 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16674 (Fbacktrace_frame): Don't assume nframes fits in int.
16676 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

16683 * cm.c (calccost): Turn while-do into do-while, for clarity.
16685 * keyboard.c (syms_of_keyboard): Use the same style as later
16686 in this function when indexing through an array. This also
16687 works around GCC bug 48267.
16689 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16691 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16693 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16694 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16696 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16697 This avoids undefined behavior on integer overflow, and is a bit
16698 more convenient anyway since it is compared to a size_t variable.
16700 Variadic C functions now count arguments with size_t, not int.
16701 This avoids an unnecessary limitation on 64-bit machines, which
16702 caused (substring ...) to crash on large vectors (Bug#8344).

16712 * fns.c (concat): Likewise.
16713 * frame.c (x_set_frame_parameters): Likewise.
16714 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16715 0 if not found, not -1. All callers changed.
16717 * alloc.c (garbage_collect): Don't assume stack size fits in int.
16718 (stack_copy_size): Now size_t, not int.
16719 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

16740 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
16741 don't set the hook to nil, but remove the offending function instead.

16743 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
16744 Vcommand_hook_internal.

16747 (funcall_nil, funcall_not): New functions.
16748 (run_hook_with_args): Call each function through a `funcall' argument.

16925 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
16927 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
16928 unconditionally since it does the check itself.
16930 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
16932 Fix more problems found by GCC 4.5.2's static checks.
16934 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16935 the first time through the loop, since we know p0 < p1 then.
16936 This also avoids a gcc -Wstrict-overflow warning.
16938 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16939 leading to a memory leak, possible in functions like
16940 load_charset_map_from_file that can allocate an unbounded number
16941 of objects (Bug#8318).
16943 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16944 that could (at least in theory) be that large.
16946 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16947 This is less likely to overflow, and avoids undefined behavior if
16948 overflow does occur. All callers changed. Use strtoul to scan
16949 for the unsigned long integer.
16950 (pint2hrstr): Simplify and tune code slightly.
16951 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
16953 * scroll.c (do_scrolling): Work around GCC bug 48228.
16954 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
16956 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
16957 This also avoids a warning with gcc -Wstrict-overflow.
16958 (validate_x_resource_name): Simplify count usage.
16959 This also avoids a warning with gcc -Wstrict-overflow.
16961 * fileio.c (Fcopy_file): Report error if fchown or fchmod
16964 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
16966 * process.c (Fmake_network_process): Use socklen_t, not int,
16967 where POSIX says socklen_t is required in portable programs.
16968 This fixes a porting bug on hosts like 64-bit HP-UX, where
16969 socklen_t is wider than int (Bug#8277).
16970 (Fmake_network_process, server_accept_connection):
16971 (wait_reading_process_output, read_process_output):
16974 * process.c: Rename or move locals to avoid shadowing.

16984 Make tparam.h and terminfo.c consistent.
16985 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
16986 Include tparam.h instead, since it declares them.
16987 * cm.h (PC): Remove extern decl; tparam.h now does this.
16988 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
16989 * terminfo.c: Include tparam.h, to check interfaces.
16990 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
16991 (tparam): Adjust signature to match interface in tparam.h;
16992 this removes some undefined behavior. Check that outstring and len
16993 are zero, which they always are with Emacs.
16994 * tparam.h (PC, BC, UP): New extern decls.
16996 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
16997 (xftfont_open): Rename locals to avoid shadowing.
16999 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

17009 * xml.c (make_dom): Now static.
17011 * composite.c (composition_compute_stop_pos): Rename local to
17013 (composition_reseat_it): Remove unused locals.
17014 (find_automatic_composition, composition_adjust_point): Likewise.
17015 (composition_update_it): Mark var as initialized.
17016 (find_automatic_composition): Mark vars as initialized,
17017 with a FIXME (Bug#8290).

17020 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
17021 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
17022 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
17023 (BUF_DEC_POS): Be more systematic about renaming local temporaries
17024 to avoid shadowing.
17026 * textprop.c (property_change_between_p): Remove; unused.
17028 * intervals.c (interval_start_pos): Now static.
17030 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

17033 Rename locals to avoid shadowing.
17035 * sound.c (wav_play, au_play, Fplay_sound_internal):
17036 Fix pointer signedness.
17037 (alsa_choose_format): Remove unused local var.
17038 (wav_play): Initialize a variable to 0, to prevent undefined
17039 behavior (Bug#8278).
17041 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
17043 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
17045 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
17046 clobbering (Bug#8298).
17047 * sysdep.c (sys_subshell): Likewise.
17048 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
17050 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
17051 This should get cleaned up, so that child_setup has the
17052 same signature on all platforms.
17054 * callproc.c (call_process_cleanup): Now static.
17055 (relocate_fd): Rename locals to avoid shadowing.
17057 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
17059 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
17060 not to be necessary, and produces flickering.
17062 2011-03-20 Glenn Morris <rgm@gnu.org>
17064 * config.in: Remove file.
17066 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
17068 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
17069 are now in src/globals.h.
17070 (syms_of_minibuf): Remove spurious & from previous change.
17072 2011-03-20 Leo Liu <sdl.web@gmail.com>
17074 * minibuf.c (completing-read-function): New variable.
17075 (completing-read-default): Rename from completing-read.
17076 (completing-read): Call completing-read-function.
17078 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
17080 * xfaces.c (Fx_load_color_file):
17081 Read color file from absolute filename (bug#8250).
17083 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
17085 * makefile.w32-in: Update dependencies.
17087 2011-03-17 Eli Zaretskii <eliz@gnu.org>
17089 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

17096 (sigchld_handler): Now static.
17098 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
17099 That way, the code declares only the vars that it needs.
17100 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
17101 * s/cygwin.h (PTY_ITERATION): Likewise.
17102 * s/darwin.h (PTY_ITERATION): Likewise.

17109 (CONSTANTLIM): Remove; unused.
17110 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
17111 Define only if needed.
17113 * unexelf.c (unexec): Name an expression,
17114 to avoid gcc -Wbad-function-cast warning.
17115 Use a different way to cause a compilation error if anyone uses
17116 n rather than nn, a way that does not involve shadowing.
17117 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
17119 * deps.mk (unexalpha.o): Remove; unused.
17121 New file unexec.h, the (simple) interface for unexec (Bug#8267).
17122 * unexec.h: New file.
17123 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
17124 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
17125 Depend on unexec.h.
17126 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
17127 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
17128 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
17129 Change as necessary to match prototype in unexec.h.
17131 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

17147 instead of using an uninitialized var.
17148 (font_sort_entities): Mark var as initialized.
17150 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
17152 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

17177 (Fcall_interactively): Rename locals to avoid shadowing.
17178 Use const pointer when appropriate.

17184 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
17185 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
17186 some of which prompt warnings from gcc -Wbad-function-cast.
17187 (Fformat_time_string, Fencode_time, Finsert_char):
17188 (Ftranslate_region_internal, Fformat):
17189 Rename or remove local vars to avoid shadowing.
17190 (Ftranslate_region_internal): Mark var as initialized.
17192 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
17195 * lisp.h (eassert): Check that the argument compiles, even if
17196 ENABLE_CHECKING is not defined.
17198 * data.c (Findirect_variable): Name an expression, to avoid
17199 gcc -Wbad-function-cast warning.
17200 (default_value, arithcompare, arith_driver, arith_error): Now static.

17208 Rename locals to avoid shadowing.
17209 (mark_stack): Move local variables into the #ifdef region where
17211 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
17212 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
17214 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
17215 (GC_STRING_CHARS): Remove; not used.
17216 (Fmemory_limit): Cast sbrk's returned value to char *.
17218 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
17219 avoids undefined behavior in theory.
17221 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
17223 Use functions, not macros, for up- and down-casing (Bug#8254).
17224 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17225 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
17226 to use the following functions instead of these macros.
17227 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
17228 EMACS_INT, since callers assume the returned value fits in int.
17229 (upcase1): Likewise, for UPCASE_TABLE.
17230 (uppercasep, lowercasep, upcase): New static inline functions.
17231 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
17232 the race-condition problem in the old DOWNCASE.
17234 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):

17236 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
17237 (regex_compile, re_search_2, re_match_2_internal):
17238 Remove unused local vars.
17239 (FREE_VAR): Rewrite so as not to use empty "else",
17240 which gcc can warn about.
17241 (regex_compile, re_match_2_internal): Mark locals as initialized.
17242 (RETALLOC_IF): Define only if needed.
17243 (WORDCHAR_P): Likewise. This one is never needed, but is used
17244 only in a comment talking about a compiler bug, so put inside
17245 the #if 0 of that comment.
17246 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
17247 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
17250 * search.c (boyer_moore): Rename locals to avoid shadowing.
17251 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
17252 (PREV_CHAR_BOUNDARY): Likewise.

17262 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
17264 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
17265 Rename locals to avoid shadowing.
17266 (Fvertical_motion): Mark locals as initialized.
17268 * casefiddle.c (casify_object, casify_region): Now static.
17269 (casify_region): Mark local as initialized.
17271 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
17273 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
17274 New macros, so that the caller can use some names other than
17275 gcpro1, gcpro2, etc.
17276 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
17278 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
17279 argument, for consistency with GCPRO2_VAR, etc: it is now the
17280 prefix of the variable, not the variable itself. All uses
17282 * dired.c (directory_files_internal, file_name_completion):
17283 Rename locals to avoid shadowing.
17285 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
17286 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
17287 dired.c's scmp function, had undefined behavior.
17288 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17289 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
17290 * buffer.h: ... to here, because these macros use current_buffer,
17291 and the new implementation with inline functions needs to have
17292 current_buffer in scope now, rather than later when the macros
17294 (downcase, upcase1): New static inline functions.
17295 (DOWNCASE, UPCASE1): Reimplement using these functions.
17296 This avoids undefined behavior in expressions like
17297 DOWNCASE (x) == DOWNCASE (y), which previously suffered
17298 from race conditions in accessing the global variables
17299 case_temp1 and case_temp2.
17300 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
17301 * lisp.h (case_temp1, case_temp2): Remove their decls.
17302 * character.h (ASCII_CHAR_P): Move from here ...
17303 * lisp.h: ... to here, so that the inline functions mentioned
17304 above can use them.
17306 * dired.c (directory_files_internal_unwind): Now static.
17308 * fileio.c (file_name_as_directory, directory_file_name):
17309 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
17311 (file_name_as_directory): Use const pointers when appropriate.
17312 (Fexpand_file_name): Likewise. In particular, newdir might
17313 point at constant storage, so make it a const pointer.
17314 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
17315 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
17317 (Fset_file_times, Finsert_file_contents, auto_save_error):
17318 Rename locals to avoid shadowing.
17320 * minibuf.c (choose_minibuf_frame_1): Now static.
17321 (Ftry_completion, Fall_completions): Rename or remove locals
17322 to avoid shadowing.
17324 * marker.c (bytepos_to_charpos): Remove; unused.
17326 * lisp.h (verify_bytepos, count_markers): New decls,
17327 so that gcc does not warn that these functions aren't declared.
17329 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
17330 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
17331 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
17332 (copy_text): Remove unused local var.
17334 * filelock.c (within_one_second): Now static.
17335 (lock_file_1): Rename local to avoid shadowing.
17337 * buffer.c (fix_overlays_before): Mark locals as initialized.
17338 (fix_start_end_in_overlays): Likewise. This function should be
17339 simplified by using pointers-to-pointers, but that's a different
17341 (switch_to_buffer_1): Now static.
17342 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
17343 (report_overlay_modification): Rename locals to avoid shadowing.
17345 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
17346 Fix pointer signedness issue.
17347 (sys_subshell): Mark local as volatile if checking for lint,
17348 to suppress a gcc -Wclobbered warning that does not seem to be right.
17349 (MAXPATHLEN): Define only if needed.
17351 * process.c (serial_open, serial_configure): Move decls from here ...
17352 * systty.h: ... to here, so that they can be checked.
17354 * fns.c (get_random, seed_random): Move extern decls from here ...
17355 * lisp.h: ... to here, so that they can be checked.
17357 * sysdep.c (reset_io): Now static.
17358 (wait_for_termination_signal): Remove; unused.
17360 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
17361 (copy_keymap_item, append_key, push_text_char_description):
17363 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
17364 (DENSE_TABLE_SIZE): Remove; unused.
17365 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
17366 (describe_map_tree):
