3 * emacs.c: Use COPYRIGHT.

7 Remove configure's --without-sync-input option (Bug#12450).
8 When auditing signal-handling in preparation for cleaning it up,
9 I found that SYNC_INPUT has race conditions and would be a real
10 pain to fix. Since it's an undocumented and deprecated
11 configure-time option, now seems like a good time to remove it.
12 Also see <http://bugs.gnu.org/11080#16>.
13 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
14 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
15 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
17 (check_depth) [XMALLOC_OVERRUN_CHECK]:
18 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
19 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
20 (dont_register_blocks, bytes_used_when_reconsidered)
21 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
22 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
23 [!SYSTEM_MALLOC && !SYNC_INPUT]:
24 Remove. All uses removed.
25 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
26 implementation, one that depends on whether the new macro
27 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
29 * atimer.c (run_timers, handle_alarm_signal):
30 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
31 (handle_async_input, process_pending_signals)
32 (handle_input_available_signal, init_keyboard):
33 * nsterm.m (ns_read_socket):
34 * process.c (wait_reading_process_output):
35 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
36 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
38 * xterm.c (XTread_socket):
40 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
41 * eval.c (handling_signal): Remove. All uses removed.
42 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
43 All uses replaced with the SYNC_INPUT version.
44 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
46 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
49 * font.c (Ffont_shape_gstring): Remove unused local.
51 2012-09-16 Glenn Morris <rgm@gnu.org>
53 * Makefile.in (clean): No longer run nextstep's clean.
55 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
57 (ns-app): Move here from ns.mk, and simplify.
58 (clean): Simplify nextstep entry.
61 2012-09-16 Kenichi Handa <handa@gnu.org>
63 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
64 not covert the last few charactes.
66 2012-09-16 Kenichi Handa <handa@gnu.org>
68 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
69 here, but just check the validity of glyphs in the glyph-string.
71 2012-09-16 Martin Rudalics <rudalics@gmx.at>
73 * window.c (Fwindow_parameter, Fset_window_parameter): Accept
74 any window as argument (Bug#12452).
76 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
78 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
79 to ns_term_init to avoid memory leak.
81 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
82 explicit retain/release.
83 (ns_term_init): Only allow one display. Initialize outerpool and
86 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
88 Port _setjmp fix to POSIXish hosts as well as Microsoft.
89 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
90 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
91 the Microsoft problem in a different way, by altering ../nt/config.nt.
93 2012-09-15 Eli Zaretskii <eliz@gnu.org>
108 * w16select.c: Remove inclusion of setjmp.h, as it is now included
109 by lisp.h. This completes removal of setjmp.h inclusion
110 erroneously announced in the previous commit. (Bug#12446)
112 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
115 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
116 not defined as a macro. The latter happens on MS-Windows.
119 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
121 Port better to POSIX hosts lacking _setjmp (Bug#12446).
122 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
123 Some instances of '#include <setjmp.h>' removed, if the
124 only reason for the instance was because "lisp.h" was included.
125 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
126 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
127 and _longjmp with the new symbols. Emacs already uses _setjmp if
128 available, so this change affects only POSIXish hosts that have
129 sigsetjmp but not _setjmp, such as some versions of Solaris and
130 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
131 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
132 (png_load_body) [HAVE_PNG]:
133 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
134 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
135 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
136 since PNG requires jmp_buf. This is the only exception to the
137 general rule that we now use sys_setjmp and sys_longjmp.
138 This exception is OK since this code does not change the signal
139 mask or longjmp out of a signal handler.
141 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
143 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
144 Include "syssignal.h", for 'main_thread'.
146 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
148 Avoid out-of-range marker position (Bug#12426).
149 * insdel.c (replace_range, replace_range_2): Adjust
150 markers before overlays, as suggested by comments.
151 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
152 Remove redundant check before calling offset_intervals.
154 2012-09-14 Martin Rudalics <rudalics@gmx.at>
156 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
157 current buffer (Bug#12387).
159 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
161 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
163 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
165 Use a more backwards-compatible timer format (Bug#12430).
166 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
167 vector element, not from the 4th, since PSECS is now at the end.
168 (Fcurrent_idle_time): Doc fix.
170 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
172 Function to mark objects and remove killed buffers at once.
173 * alloc.c (discard_killed_buffers): Rename to ...
174 (mark_discard_killed buffers) ... new name. Add marking
175 of remaining objects. Fix comment. Adjust users.
176 (mark_object): Do not touch frame buffer lists here.
177 * frame.c (delete_frame): Reset frame buffer lists here.
179 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
181 Better workaround for GNOME bug when --enable-gcc-warnings.
182 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
183 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
184 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
186 Simplify SIGIO usage (Bug#12408).
187 The code that dealt with SIGIO was crufty and confusing, e.g., it
188 played tricks like "#undef SIGIO" but these tricks were not used
189 consistently. Simplify mostly by not #undeffing standard symbols,
190 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
191 or not as we please) rather than "defined SIGIO" (standard symbol
192 that we probably shouldn't #undef).
193 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
194 Modules that need it can include it.
195 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
196 * dispextern.h (ignore_sigio): New decl.
197 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
198 unconditionally, since it's now a no-op if !USABLE_SIGIO.
199 * emacs.c (shut_down_emacs):
200 * keyboard.c (kbd_buffer_store_event_hold):
201 Use ignore_sigio rather than invoking 'signal' directly.
202 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
204 (FIONREAD, SIGIO): Do not #undef.
205 (tty_read_avail_input): Use #error rather than a syntax error.
206 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
207 for I_PIPE, used by SETUP_SLAVE_PTY.
208 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
209 * sysdep.c (croak): Remove; no longer needed. This bit of
210 temporary code, with Fred N. Fish's comment that it's temporary,
211 has been in Emacs since at least 1992!
212 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
213 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
214 * syssignal.h (croak): Remove decl.
215 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
216 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
217 now that we're termios-only.
218 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
219 * term.c (dissociate_if_controlling_tty): Use #error rather than
222 Work around GCC and GNOME bugs when --enable-gcc-warnings.
223 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
224 to work around GNOME bug 683906.
225 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
226 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
227 This works around GCC bug 54561.
229 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
231 More fixes for 'volatile' and setjmp/longjmp.
232 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
233 * image.c (struct png_load_context) [HAVE_PNG]: New type.
234 (png_load_body) [HAVE_PNG]:
235 (jpeg_load_body) [HAVE_JPEG]:
236 New function, with most of the old parent function's body.
237 (png_load) [HAVE_PNG]:
238 (jpeg_load) [HAVE_JPEG]:
239 Invoke the new function, to avoid longjmp munging our locals.
240 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
241 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
242 longjmp is passed 2, as the C standard doesn't guarantee this.
243 Instead, store the failure code into mgr->failure_code.
245 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
247 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
248 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
249 (syms_of_keyboard): Remove support for unread-command-char.
251 2012-09-12 Eli Zaretskii <eliz@gnu.org>
253 * w32proc.c (sys_kill): If PID is our process ID and the signal is
254 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
255 violation. (Bug#12426)
257 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
259 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
261 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
263 * eval.c: Add `inhibit-debugger'.
264 (Qinhibit_debugger): New symbol.
265 (call_debugger): Bind it instead of Qdebug_on_error.
266 (maybe_call_debugger): Test Vinhibit_debugger.
267 (syms_of_eval): Define inhibit-debugger.
268 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
269 (syms_of_xdisp): Remove inhibit-debug-on-message.
271 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
273 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
274 If a nonvolatile local variable is written before a _longjmp to
275 the frame containing the variable, and is read after the _longjmp,
276 the value read is indeterminate. Some local variables of type
277 'struct handler' and 'struct catchtag' are used in this way, so
278 mark each of their slots as volatile if the slot can be set before
279 _longjmp and read afterwards.
280 * lisp.h (struct handler): var and chosen_clause are now volatile.
281 (struct catchtag): val, next, and pdlcount are now volatile.
283 * bidi.c (bidi_push_it, bidi_pop_it):
284 * fns.c (copy_hash_table):
285 * image.c (define_image_type):
286 * keyboard.c (kbd_buffer_store_event_hold):
287 * process.c (Fprocess_send_eof):
288 * xfaces.c (x_create_gc) [HAVE_NS]:
289 * xgselect.c (xg_select):
290 Prefer assignment to memcpy when either will do.
292 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
293 Use pointer-to-a-pointer to simplify and avoid a NILP check each
294 time an item is removed. No need to mark this function 'inline';
295 the compiler knows better than we do.
297 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
299 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
300 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
301 to change_frame_size (Bug#12388).
302 (windowDidResize:): Pass YES to updateFrameSize.
304 * nsterm.h: Add delay parameter to updateFrameSize.
306 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
308 Discard killed buffers from deleted window and frame objects.
309 This reduces an amount of references to killed buffers and
310 helps GC to reclaim them faster.
311 * alloc.c (discard_killed_buffers): New function.
312 (mark_object): Use it for deleted windows and frames.
313 (mark_object): If symbol's value is set up for a killed buffer
314 or deleted frame, restore it's global binding.
315 * data.c (swap_in_global_binding): Add GC notice.
316 (swap_in_symval_forwarding): Use convenient set_blv_where.
317 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
318 * window.h: ... to here.
320 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
322 Convenient macro to check whether the buffer is live.
323 * buffer.h (BUFFER_LIVE_P): New macro.
324 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
325 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
327 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
329 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
330 composition cases (Bug#12364).
332 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
333 overhang of succeeding glyphs overlapping box cursor.
335 * w32term.c (x_draw_glyph_string): Likewise.
337 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
339 Simplify, document, and port floating-point (Bug#12381).
340 The porting part of this patch fixes bugs on non-IEEE platforms
341 with frexp, ldexp, logb.
342 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
344 * floatfns.c: Simplify discussion of functions that Emacs doesn't
345 support, by removing commented-out code and briefly listing the
346 C89 functions excluded. The commented-out stuff was confusing
347 maintenance, e.g., we thought we needed cbrt but it was commented out.
348 (logb): Remove decl; no longer needed.
349 (isfinite): New macro, if not already supplied.
350 (isnan): Don't replace any existing macro.
351 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
352 are present on all C89 platforms.
353 (Ffrexp): Do not special-case zero, as frexp does the right thing
355 (Flogb): Do not use logb, as it doesn't have the desired meaning
356 on hosts that use non-base-2 floating point. Instead, stick with
357 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
358 frexp, to avoid getting an unspecified result.
360 * xdisp.c (Qinhibit_debug_on_message): Now static.
362 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
364 * nsterm.m (ns_update_begin): Set clip path to whole view by using
365 NSBezierPath (Bug#12131).
367 2012-09-10 Chong Yidong <cyd@gnu.org>
369 * fns.c (Fdelq, Fdelete): Doc fix.
371 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
373 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
374 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
376 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
378 * lisp.h (make_lisp_ptr): New macro to replace XSET.
379 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
382 2012-09-09 Eli Zaretskii <eliz@gnu.org>
384 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
385 left fringe if the window has a left margin. This avoids leaving
386 traces of the cursor because its leftmost pixel is not drawn over.
388 * dispnew.c (update_window_line): When the left margin area of a
389 screen line is updated, set the redraw_fringe_bitmaps_p flag of
390 that screen line. (Bug#12277)
392 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
394 Assume C89 or later for math functions (Bug#12381).
395 This simplifies the code, and makes it a bit smaller and faster,
396 and (most important) makes it easier to clean up signal handling
397 since we can stop worring about floating-point exceptions in
398 library code. That was a problem before C89, but the problem
399 went away many years ago on all practical Emacs targets.
400 * data.c, image.c, lread.c, print.c:
401 Don't include <math.h>; no longer needed.
402 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
403 might be autoconfigured, as that never happens.
405 * doprnt.c (DBL_MAX_10_EXP):
407 Remove. C89 or later always defines these.
408 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
409 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
410 (arith_error, domain_error, domain_error2):
411 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
412 no longer needed -- we simply return what C returns. All uses removed.
413 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
415 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
416 Remove. All uses expanded, as these macros are no longer used
417 more than once and are now more trouble than they're worth.
418 (Ftan): Use tan, not sin / cos.
419 (Flogb): Assume C89 frexp.
420 (fmod_float): Assume C89 fmod.
421 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
422 (init_floatfns): Remove. All uses removed.
424 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
426 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
427 compositeToPoint for OSX < 10.6 (Bug#12390).
429 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
431 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
432 This produces more-accurate results.
434 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
436 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
439 2012-09-08 Chong Yidong <cyd@gnu.org>
441 * syntax.c (Fstring_to_syntax): Doc fix.
443 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
445 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
446 in the internal border.
447 (x_set_window_size): Remove static variables and their usage.
448 (ns_redraw_scroll_bars): Fix NSTRACE arg.
449 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
450 fringe/internal border adjustment (Bug#11052).
451 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
452 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
453 (ns_fix_rect_ibw): Remove.
454 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
455 (ns_dumpglyphs_box_or_relief): Ditto.
456 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
458 (ns_dumpglyphs_image): Ditto.
459 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
461 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
462 their usage. Add fringe_extended_p and its use as in other terms.
463 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
464 scroll bar was removed.
465 (updateFrameSize): New function.
466 (windowDidResize): Move code to updateFrameSize and call it.
468 * nsterm.h (EmacsView): Add updateFrameSize.
470 2012-09-07 Chong Yidong <cyd@gnu.org>
472 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
474 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
476 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
478 More signal-handler cleanup (Bug#12327).
479 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
480 Problem introduced when merging patches. Noted by Eli Zaretskii in
481 <http://bugs.gnu.org/12327#67>.
482 * floatfns.c: Comment fix.
483 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
484 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
485 and anyway the declaration is harmless even if SIGDANGER is not defined.
486 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
487 defined BROKEN_FIONREAD). systty.h formerly did this, but other
488 source files not surprisingly expected syssignal.h to define, or
489 not define, SIGIO, and it's cleaner to do it that way, for consistency.
490 Include <sys/ioctl.h>, for FIONREAD.
491 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
492 This eliminates a problem whereby other files mysteriously had
493 to include "syssignal.h" before including "systty.h" if they
494 wanted to use "#ifdef SIGIO".
496 2012-09-07 Eli Zaretskii <eliz@gnu.org>
498 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
500 * w32.c (sigemptyset): Empty the set.
501 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
503 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
505 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
507 * alloc.c (mark_buffer): Revert unsafe marking optimization.
508 (mark_object): Likewise for frame objects.
510 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
512 * syssignal.h (handle_on_main_thread): Always declare,
513 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
514 This ports to platforms without HAVE_PTHREAD.
516 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
518 Signal-handler cleanup (Bug#12327).
519 Emacs's signal handlers were written in the old 4.2BSD style with
520 sigblock and sigmask and so forth, and this led to some
521 inefficiencies and confusion. Rewrite these to use
522 pthread_sigmask etc. without copying signal sets around. Also,
523 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
524 'signal', and instead use functions that do not attempt to take
525 over the system name space. This patch causes Emacs's text
526 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
527 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
528 Do not include <signal.h> or "syssignal.h", as these
529 modules do not use signals.
530 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
531 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
532 Do not include <signal.h>, as "syssignal.h" does that for us now.
533 * atimer.c (sigmask_atimers): New function.
534 (block_atimers, unblock_atimers): New functions,
535 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
537 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
538 no longer needed here.
539 * emacs.c (main): Inspect existing signal handler with sigaction,
540 so that there's no need to block and unblock SIGHUP.
541 * sysdep.c (struct save_signal): New member 'action', replacing
542 old member 'handler'.
543 (save_signal_handlers, restore_signal_handlers):
544 Use sigaction instead of 'signal' to save and restore.
545 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
546 New function. All users of 'signal' modified to use set_sighandler
547 if they're writeonly, and to use sys_signal if they're read+write.
548 (emacs_sigaction_init, forwarded_signal): New functions.
549 (sys_signal): Remove. All uses replaced by calls to sigaction
550 and emacs_sigaction_init, or by direct calls to 'signal'.
551 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
552 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
553 all uses replaced by pthread_sigmask etc. calls.
554 * syssignal.h: Include <signal.h>.
555 (emacs_sigaction_init, forwarded_signal): New decls.
556 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
557 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
558 (sigmask, sys_sigmask): Remove; no longer needed.
559 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
560 (sigblock, sigunblock, sigfree):
561 (sigsetmask) [!defined sigsetmask]:
562 Remove. All uses replaced by pthread_sigmask.
563 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
564 no longer need to be replaced, and its typical old uses
565 are now done via emacs_sigaction_init and sigaction.
566 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
567 (sys_sigdel): Remove; unused.
568 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
570 2012-09-06 Eli Zaretskii <eliz@gnu.org>
572 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
573 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
575 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
577 Explicitly mark buffer_defaults and buffer_local_symbols.
578 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
579 mark_local_symbols here.
580 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
581 since special buffers aren't marked here any more.
582 (allocate_buffer): Chain new buffer with all_buffers here...
583 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
585 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
586 (syms_of_buffer): Remove staticpro of the above.
587 (init_buffer_once): Set names for buffer_defaults and
588 buffer_local_symbols.
590 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
592 Use bool for booleans in font-related modules.
593 * font.c (font_intern_prop, font_style_to_value)
594 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
595 (generate_otf_features, font_check_otf_features, font_check_otf)
596 (font_match_p, font_list_entities, font_at):
597 * fontset.c (fontset_id_valid_p, reorder_font_vector
598 (fontset_find_font, Fset_fontset_font)
599 (face_suitable_for_char_p) [0]:
600 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
601 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
602 (m17n_flt_initialized, ftfont_shape_by_flt):
603 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
604 * nsfont.m (nsfont_draw):
605 * w32font.c (w32font_draw):
606 * w32term.c (x_draw_glyphless_glyph_string_foreground):
607 Use bool for booleans.
608 * font.h: Adjust to above API changes.
609 (struct font, struct font_driver, struct font_driver_list):
610 Use bool for booleans.
611 (struct font): Remove useless member encoding_type.
613 * fontset.c, xftfont.c: Omit unnecessary static decls.
615 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
617 * alloc.c (mark_object): Revert window marking code
618 since it's unsafe for the Fset_window_configuration.
620 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
622 Fix race conditions with signal handlers and errno (Bug#12327).
623 Be more systematic about preserving errno whenever a signal
624 handler returns, even if it's not in the main thread. Do this by
625 renaming signal handlers to distinguish between signal delivery
626 and signal handling. All uses changed.
627 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
628 * data.c (deliver_arith_signal): Rename from arith_error.
629 * dispnew.c (deliver_window_change_signal): Rename from
630 window_change_signal.
631 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
632 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
633 * keyboard.c (deliver_input_available_signal): Rename from
634 input_available_signal.
635 (deliver_user_signal): Rename from handle_user_signal.
636 (deliver_interrupt_signal): Rename from interrupt_signal.
637 * process.c (deliver_pipe_signal): Rename from send_process_trap.
638 (deliver_child_signal): Rename from sigchld_handler.
639 * atimer.c (handle_alarm_signal):
640 * data.c (handle_arith_signal):
641 * dispnew.c (handle_window_change_signal):
642 * emacs.c (handle_fatal_signal, handle_danger_signal):
643 * keyboard.c (handle_input_available_signal):
644 * keyboard.c (handle_user_signal, handle_interrupt_signal):
645 * process.c (handle_pipe_signal, handle_child_signal):
646 New functions, with the actual signal-handling code taken from the
647 original respective signal handlers, sans the sporadic attempts to
648 preserve errno, since that's now done by handle_on_main_thread.
649 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
650 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
651 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
653 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
654 Move initialization of main_thread to sysdep.c's init_signals.
655 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
656 our usage, and simplifies the mainline code.
657 (record_child_status_change): New static function, as a helper
658 for handle_child_signal, and with most of the old child handler's
660 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
661 (handle_child_signal): Use the above.
662 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
663 Moved here from emacs.c.
664 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
665 code moved here from emacs.c's main function.
666 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
667 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
668 lets callers save and restore errno properly.
670 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
672 Remove redundant or unused things here and there.
673 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
674 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
675 * editfns.c (Fcompare_buffer_substrings): Likewise.
676 * frame.h (struct terminal, struct font_driver_list):
677 Remove redundant declarations.
678 * window.h (Qleft, Qright): Likewise.
680 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
682 Do not mark objects from deleted buffers, windows and frames.
683 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
684 (mark_object): Likewise for windows and frames.
686 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
688 * alloc.c (valid_lisp_object_p): Treat killed buffers,
689 buffer_defaults and buffer_local_symbols as valid objects.
690 Return special value to denote them.
692 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
694 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
695 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
696 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
697 (file_name_absolute_p, Fsubstitute_in_file_name):
698 (check_executable, check_writable, Ffile_accessible_directory_p)
699 (Fset_file_selinux_context, Fdefault_file_modes)
700 (Finsert_file_contents, choose_write_coding_system)
701 (Fwrite_region, build_annotations, a_write, e_write)
703 * filelock.c (boot_time_initialized, get_boot_time)
704 (get_boot_time_1, lock_file_1, within_one_second):
705 * floatfns.c (in_float):
706 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
707 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
708 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
709 * lisp.h (struct Lisp_Hash_Table.cmpfn):
710 * window.c (compare_window_configurations):
711 Use bool for booleans.
712 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
713 (Fdefault_file_modes): Now mode_t, not int, for modes.
714 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
715 (internal_delete_file): Now returns void, not a (boolean) int,
716 since nobody was looking at the return value.
717 * lisp.h, window.h: Adjust to above API changes.
719 * xdisp.c (set_message): Simplify and reindent last change.
721 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
723 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
725 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
727 * eval.c (call_debugger): Make the function non-static so that we
728 can call it from set_message.
730 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
731 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
733 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
735 Give more-useful info on a fatal error (Bug#12328).
736 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
737 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
738 of doing the work ourselves.
739 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
741 (fatal_error_backtrace): New function, taken from the guts
742 of the old fatal_error_signal, but with a new option to output
744 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
745 info about the signal than just its number.
746 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
747 * sysdep.c: Include <execinfo.h>
748 (emacs_backtrace): New function, taken partly from the previous
749 code of the 'die' function.
750 (emacs_abort): Call fatal_error_backtrace rather than abort.
752 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
754 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
755 eager (load-time) macro-expansion.
756 * lisp.mk (lisp): Add macroexp.
758 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
760 Simplify redefinition of 'abort' (Bug#12316).
761 Do not try to redefine the 'abort' function. Instead, redo
762 the code so that it calls 'emacs_abort' rather than 'abort'.
763 This removes the need for the NO_ABORT configure-time macro
764 and makes it easier to change the abort code to do a backtrace.
765 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
766 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
767 Remove; sysdep.c's emacs_abort now takes its place.
768 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
769 'abort' changed to use 'emacs_abort'.
770 * msdos.c (dos_abort) [defined abort]: Remove; not used.
771 (abort) [!defined abort]: Rename to ...
772 (emacs_abort): ... new name.
773 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
774 the place of the old 'abort' in emacs.c.
775 * w32.c, w32fns.c (abort): Do not #undef.
776 * w32.c (emacs_abort): Rename from w32_abort.
778 2012-09-04 Eli Zaretskii <eliz@gnu.org>
780 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
781 offsets[j].dv, since the y axis of the screen coordinates points
782 down, while the y axis of the font definition coordinates points
783 up. This fixes display of Arabic diacritics such as KASRA and
784 KASRATAN. (Bug#11860)
786 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
788 Be more systematic about _setjmp vs setjmp.
789 * alloc.c (test_setjmp, mark_stack):
790 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
791 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
792 (png_load, my_error_exit, jpeg_load):
793 * process.c (send_process_trap, send_process):
794 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
795 The underscored versions are up to 30x faster on some hosts.
796 Formerly, the code used setjmp+longjmp sometimes and
797 _setjmp+_longjmp at other times, with no particular reason to
798 prefer setjmp+longjmp.
800 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
802 Fix minor problem found by static checking.
803 * buffer.c (Fdelete_all_overlays): Return nil.
805 2012-09-03 Martin Rudalics <rudalics@gmx.at>
807 * buffer.c (Fdelete_all_overlays): New function.
809 2012-09-03 Chong Yidong <cyd@gnu.org>
811 * gtkutil.c: Add extern decl for Qxft.
813 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
815 * emacs.c, eval.c: Use bool for boolean.
816 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
817 (malloc_using_checking) [DOUG_LEA_MALLOC]:
818 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
819 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
820 (main, decode_env_path, Fdaemon_initialized):
821 * eval.c (call_debugger, Finteractive_p, interactive_p):
822 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
823 (maybe_call_debugger, Fbacktrace):
824 * process.c (read_process_output, exec_sentinel):
825 Use bool for booleans.
826 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
828 * eval.c (interactive_p): Omit always-true boolean argument
829 EXCLUDE_SUBRS_P. All callers changed.
830 * dispextern.h, lisp.h: Reflect above API changes.
831 * firstfile.c (dummy): Use the address of 'main', whose signature
832 won't change, instead of the address of 'initialize', whose
833 signature just changed from int to bool.
834 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
835 * msdos.c (fatal_error_in_progress): ... from here.
836 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
838 (redisplay_internal, unwind_redisplay): Simply clear
839 REDISPLAYING_P when unwinding, instead of saving its previous,
840 always-false value and then restoring it.
842 Clean up some extern decls.
843 Mostly, this hoists extern decls out of .c files and into .h files.
844 That way, we're more likely to catch errors if the interfaces change.
845 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
846 declare xg_mark_data.
847 * dispextern.h (x_frame_parm_handlers):
849 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
850 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
851 (Qultra_bold, Qoblique, Qitalic):
852 Move extern decl here from .c file.
853 * alloc.c (xg_mark_data) [USE_GTK]:
855 * eval.c (Qlexical_binding):
856 * fns.c (time) [!HAVE_UNISTD_H]:
857 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)

860 * lread.c (Qinternal_interpreter_environment):
861 * minibuf.c (Qbuffer):
862 * process.c (QCfamily, QCfilter):
863 * widget.c (free_frame_faces):
864 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
865 * xfont.c (x_clear_errors):
866 * xterm.c (x_frame_parm_handlers):
867 Remove now-redundant extern decls.
868 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
869 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
871 * xfaces.c: Remove unnecessary static decls.
872 * xterm.c (updating_frame): Remove decl of nonexistent object.
874 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
875 when building globals.h, as the objects that are not built on
876 this host are not needed to compile C files on this host.
878 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
880 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
882 * frame.h: Add missing prototype for x_wm_set_size_hint.
884 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

909 Use bool for boolean.
910 * intervals.h, lisp.h, systime.h: Reflect above API changes.
911 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
913 2012-09-02 Chong Yidong <cyd@gnu.org>
915 * keymap.c (push_key_description): Print M-TAB as C-M-i
918 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
920 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

928 2012-09-01 Eli Zaretskii <eliz@gnu.org>
930 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
931 more than one grapheme cluster passed to the shaper: compute the
932 offset adjustment values separately for each cluster. (Bug#11860)
934 * image.c: Restore mistakenly removed inclusion of w32.h. Without
935 it, GCC doesn't see prototypes of w32_delayed_load, and complains
936 about implicit conversions from integer to pointer.
938 2012-09-01 Daniel Colascione <dancol@dancol.org>
940 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

956 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
957 x_wm_set_size_hint, x_query_colors, x_real_positions,
958 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
959 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
960 all of which have been moved to common code.

994 window system declarations.
996 * frame.h: Move common functions here: set_frame_menubar,
997 x_set_window_size, x_sync, x_get_focus_frame,
998 x_set_mouse_position, x_set_mouse_pixel_position,
999 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
1000 x_char_width, x_char_height, x_pixel_width, x_pixel_height,
1001 x_set_frame_alpha, x_set_menu_bar_lines, x_set_tool_bar_lines,
1002 x_activate_menubar, x_real_positions, x_bitmap_icon,
1003 x_set_menu_bar_lines, free_frame_menubar, x_free_frame_resources,
1006 * frame.c: Include TERM_HEADER instead of listing all possible
1007 window-system headers.
1009 * font.c: Include TERM_HEADER instead of listing all possible
1010 window-system headers.
1012 * emacs.c: Include TERM_HEADER.
1014 * dispnew.c: Include TERM_HEADER instead of listing all possible
1015 window-system headers.
1017 * ccl.h: Include character.h.
1019 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
1020 the current window system; include in list of objects to link into
1023 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
1025 Remove mark_ttys function and fix tty_display_info initialization.
1026 * lisp.h (mark_ttys): Remove prototype.
1027 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call

1029 the frames which are reachable from Vframe_list.
1030 * term.c (mark_ttys): Remove.
1031 (init_tty): Safely initialize 'top_frame' slot with Qnil.
1033 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
1035 Change struct frame bitfields from unsigned char to unsigned.
1036 * frame.h (struct frame): Change type of 'display_preempted',
1037 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',

1050 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
1051 does not become zero (Bug#12234).
1053 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
1055 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
1056 for GCC 4.7.1 x86-64.
1058 2012-08-30 Glenn Morris <rgm@gnu.org>
1060 * lread.c (init_lread): For out-of-tree builds, only add the
1061 source directory's site-lisp dir to the load-path if it exists,
1062 consistent with in-tree builds. (Bug#12302)
1064 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
1066 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
1067 button_values to NULL. Call setStykeMask so dialogs get a close button.
1068 (windowShouldClose:): Set window_closed.
1069 (dealloc): New member, free button_values.
1070 (process_dialog:): Make member function. Remove window argument,

1081 (timeout_handler:): Set timer_fired to YES.
1082 (runDialogAt:): Set timer_fired to NO.
1083 Handle click on close button as quit.
1085 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
1086 Add window_closed and button_values. Add void as return value for
1087 add(Button|String|Split). addButton takes int instead of Lisp_Object.
1088 Add process_dialog as new member.
1090 2012-08-28 Eli Zaretskii <eliz@gnu.org>
1092 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
1093 is not one of the heaps we manage. (Bug#12242)
1095 2012-08-28 Glenn Morris <rgm@gnu.org>
1097 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

1159 * dispextern.h (struct composition_it): Use bool for boolean.
1160 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
1161 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
1162 * dired.c (file_name_completion):
1163 Use bool for boolean. (This was missed in an earlier change.)
1165 2012-08-27 Martin Rudalics <rudalics@gmx.at>
1167 * window.c (Fset_window_configuration): Revert first part of
1170 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>

1228 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
1229 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
1230 not a boolean 'int', since callers never look at the return value.
1231 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
1232 * coding.h (decoding_buffer_size, encoding_buffer_size)
1233 (emacs_mule_string_char): Remove unused extern decls.
1234 (struct iso_2022_spec, struct coding_system):

1250 buffer doesn't appear in the selected window, go to its old
1253 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
1255 Special MEM_TYPE_SPARE to denote reserved memory.
1256 * alloc.c (enum mem_type): New memory type.
1257 (refill_memory_reserve): Use new type for spare memory.
1258 This prevents live_cons_p and live_string_p from incorrect

1261 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
1264 * Makefile.in (.PHONY): versioclean -> versionclean.

1268 * window.c (Qwindow_valid_p, decode_valid_window):
1269 Now static, not extern.
1270 * data.c (Qinterval): Remove; unused.

1287 (map_sub_char_table):
1288 Use bool for boolean.
1289 * character.c (str_to_unibyte): Omit last boolean argument; it was
1290 always 0. All callers changed.
1291 * character.h, charset.h: Adjust to match previous changes.
1292 * character.h (char_printable_p): Remove decl of nonexistent function.
1293 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
1294 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
1295 are all boolean, so make them single-bit bitfields.
1297 * lisp.h (ASET): Remove attempt to detect side effects.
1298 It was meant to be temporary and it often doesn't work,
1299 because when IDX has side effects the behavior of IDX==IDX
1300 is undefined. See Stefan Monnier in
1301 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
1303 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
1305 * lisp.h (functionp): New function (extracted from Ffunctionp).
1306 (FUNCTIONP): Use it.
1307 * eval.c (Ffunctionp): Use it.
1309 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1311 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
1312 as that's faster and simpler than static storage. Don't bother
1313 with the g_main_context_query overhead if g_main_context_pending
1314 says no events are pending.
1315 (gfds, gfds_size): Remove these static vars.
1316 (xgselect_initialize): Remove; no longer needed.
1317 All uses and decls removed.
1319 * emacs.c (fatal_error_signal_hook): Remove.
1320 All uses removed. This leftover from old code was always 0.
1322 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
1323 * casefiddle.c (casify_object, casify_region):
1324 * casetab.c (set_case_table):

1326 * category.h (CHAR_HAS_CATEGORY):
1327 Use bool for booleans, instead of int.
1329 2012-08-25 Eli Zaretskii <eliz@gnu.org>
1331 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.

1335 On assertion failure, print backtrace if available.
1336 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1337 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1338 * Makefile.in (LIB_EXECINFO): New macro.
1341 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1342 * bytecode.c (exec_byte_code):
1343 * callint.c (check_mark, Fcall_interactively):
1344 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1345 (getenv_internal, sync_process_alive, call_process_exited):
1346 * lisp.h (USE_SAFE_ALLOCA):
1347 Use bool for booleans, instead of int.
1348 * lisp.h, process.h: Adjust prototypes to match above changes.
1349 * callint.c (Fcall_interactively): Don't assume the mark's
1350 offset fits in 'int'.
1352 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1354 * buffer.c, buffer.h: Use bool for boolean.
1355 * buffer.c (reset_buffer_local_variables)

1361 (mmap_enlarge, mmap_set_vars):
1362 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1363 Use bool for booleans, instead of int.
1364 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1365 since the 1-or-0 return value is always ignored anyway.
1366 (mmap_initialized_p):
1367 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1368 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1370 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1372 * bidi.c: Use bool for boolean.
1373 This is a bit more readable, and makes the text segment of bidi.o
1374 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1375 Presumably it's faster too.
1376 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1378 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1379 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1380 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1381 (bidi_explicit_dir_char, bidi_level_of_next_char)
1382 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1383 Use bool for booleans, instead of int.
1384 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1385 (bidi_unshelve_cache): Adjust decls to match code.
1387 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1389 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1392 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1394 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1395 * atimer.h: Include <stdbool.h>.
1397 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1399 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1400 compile time tests instead of run time tests on systems that do
1402 (FRAME_MAC_P): Remove leftover from deleted code.
1403 * frame.c (syms_of_frame): Remove leftover from deleted code.
1405 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
1407 * nsterm.m (insertText:): Don't clear modifiers if code is space.
1409 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1411 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1412 Otherwise, the compiler complains about (A?B:C) where B is void
1413 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1414 (fontset_add): Return void, for FONTSET_ADD.
1416 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1418 * alloc.c: Use bool for booleans.
1419 (gc_in_progress, abort_on_gc)
1420 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1421 (dont_register_blocks) [GC_MALLOC_CHECK]:
1422 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1423 (check_string_bytes, make_specified_string, memory_full)
1424 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1425 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1426 (mark_stack, valid_pointer_p, make_pure_string)
1427 (Fgarbage_collect, survives_gc_p, gc_sweep):
1428 Use bool for booleans, instead of int.
1429 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1430 Remove unused local.
1431 * alloc.c (PURE_POINTER_P):
1432 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1433 * editfns.c (Fformat):
1434 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1436 * fns.c (sweep_weak_table):
1437 * lisp.h (suppress_checking, push_message, survives_gc_p)
1438 (make_pure_string, gc_in_progress, abort_on_gc):
1439 * lread.c (readchar, read1):
1440 * print.c (Fprin1_to_string):
1441 * xdisp.c (push_message):
1442 Use bool for booleans affected directly or indirectly by
1445 Make recently-introduced setters macros.
1446 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1447 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1448 (set_fontset_default, set_fontset_fallback): Rename from their
1449 upper-case counterparts, and make them functions rather than macros.
1450 This is more consistent with the other recently-introduced setters.
1451 These don't need to be inline, since they're local.
1453 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1455 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1456 the loop (Bug#12247).
1458 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1460 * lisp.h (vcopy): Use memcpy rather than our own loop.
1461 This fixes a performance regression introduced by the recent
1462 addition of vcopy. This means 'vcopy' will need to be modified
1463 for a copying collector, but that's OK. Also, tighten the
1464 checking in the assertion.
1466 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1468 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1469 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1470 non-base glyph for the width of the base character, according to
1471 what x_draw_composite_glyph_string_foreground expects.
1472 Generate WADJUST value according to composition_gstring_width's
1473 expectations, to produce correct width of the composed character.
1474 Reverse the sign of the DU offset produced by ScriptPlace.
1476 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1478 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1480 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1482 Avoid direct writes to contents member of struct Lisp_Vector.
1483 * lisp.h (vcopy): New function to copy data into vector.
1484 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
1485 * fns.c (Ffillarray): Use ASET.
1486 * keyboard.c (timer_check_2): Use AREF and ASET.
1487 (append_tool_bar_item, Frecent_keys): Use vcopy.
1488 * lread.c (read_vector): Use ASET.
1489 * msdos.c (Frecent_doskeys): Use vcopy.
1490 * xface.c (Finternal_copy_lisp_face): Use vcopy.
1491 (Finternal_merge_in_global_face): Use ASET and vcopy.
1492 * xfont.c (xfont_list_pattern): Likewise.

1497 the position of its buffer's point.
1498 (Fset_window_point): For the selected window always go in its
1499 buffer to the specified position.
1501 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1503 Setter macros for fontsets.
1504 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1505 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1506 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1509 2012-08-20 Glenn Morris <rgm@gnu.org>
1511 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1512 Don't assume that `ln -f' works.
1514 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1516 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1517 and later about non-assignments with no effect. See discussion at
1518 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1521 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1523 Inline setter functions for Lisp_Objects slots of struct specbinding.
1524 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
1527 2012-08-20 Martin Rudalics <rudalics@gmx.at>
1529 * window.c (select_window): Always make selected window's buffer
1532 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1534 Use AREF and ASET for docstrings of category tables.
1535 * category.h (CATEGORY_DOCSTRING): Use AREF.
1536 (SET_CATEGORY_DOCSTRING): Use ASET.
1537 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
1539 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1541 Inline setter functions for hash table members.
1542 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
1543 (set_hash_hash, set_hash_index): Rename with _slot suffix.
1544 (set_hash_key_and_value, set_hash_index, set_hash_next)
1545 (set_hash_hash): New functions.
1546 * charset.c, fns.c: Adjust users.
1548 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1550 Inline getter and setter functions for per-buffer values.
1551 * buffer.h (per_buffer_default, set_per_buffer_default)
1552 (per_buffer_value, set_per_buffer_value): New functions.
1553 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
1554 * buffer.c, data.c: Adjust users.
1556 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
1558 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
1560 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
1562 Rely on <config.h> + <unistd.h> to declare 'environ',
1563 as gnulib does this if the system doesn't.
1564 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
1565 Remove declaration. MS-Windows declares it on stdlib.h which is
1566 included by conf_post.h.
1567 * emacs.c (environ) [DOUG_LEA_MALLOC]:
1568 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
1569 * vm-limit.c: Include <unistd.h>, for 'environ'.
1571 * unexaix.c, unexcoff.c: Include "mem-limits.h".
1572 (start_of_data): Remove decl; mem-limits.h provides it.
1574 * xdisp.c (handle_invisible_prop): Make it a bit faster
1575 and avoid a gcc -Wmaybe-uninitialized diagnostic.
1577 2012-08-19 Chong Yidong <cyd@gnu.org>
1579 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
1582 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
1584 * .gdbinit: Use call instead of set when calling a function in the
1587 * data.c (set_internal): Don't use set_blv_found.
1588 (Fkill_local_variable): Likewise.
1590 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
1592 * nsfont.m (ns_ascii_average_width): Ensure the string
1593 ascii_printable is initialized with a null-terminated character
1594 array. Otherwise, it can contain undesired extra characters.
1596 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1598 port new setting code to Sun C 5.8 2005/10/13
1599 * chartab.c, lisp.h (char_table_set, char_table_set_range):
1600 Return void, not Lisp_Object. Otherwise, the compiler
1601 complains about (A?B:C) where B is void and C is Lisp_Object
1602 when compiling CHAR_TABLE_SET, due to the recent change to
1603 the API of sub_char_table_set_contents.
1605 2012-08-18 Chong Yidong <cyd@gnu.org>
1607 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
1608 for the string case (Bug#3874).

1763 The old version was confusing because it used the same name
1764 'parent' for two different things.
1766 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
1768 Functions to get and set Lisp_Object fields of buffer-local variables.

1777 font spec, make the font's attributes take precedence over
1778 directly-specified attributes.
1779 (merge_face_ref): Recognize :font.
1781 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

2435 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
2436 * w32.c (init_environment): Change the default values of many
2437 environment variables in dflt_envvars[] to NULL, to avoid pushing
2438 them into environment when they were not already defined.
2439 Remove the code that deletes site-lisp subdirectories from the default
2440 value of EMACSLOADPATH, as it is no longer needed.
2441 (check_windows_init_file): Now external, not static.
2442 Use Vload_path as is, without adding anything, as this function is now
2443 called when Vload_path is already set up.
2445 * w32.h (check_windows_init_file): Add prototype.
2447 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

2454 installation tree, as appropriate.
2456 * callproc.c (init_callproc_1): Call decode_env_path instead of
2457 doing its equivalent by hand.

2459 the code that sets Vexec_path run on MS-Windows.
2461 * lread.c (init_lread): Add comments to #ifdef's.
2463 * msdos.c (dos_set_window_size, IT_update_begin)

2490 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
2491 Remove unnecessary pointer casts.
2492 * alloc.c (record_xmalloc): New function.
2493 * lisp.h (record_xmalloc): New decl.
2494 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
2495 more like a function. This is because the pointer cast is not
2496 needed. All uses changed.
2497 * print.c (print_string, print_error_message): Avoid length recalc.
2499 Improve fix for macroexp crash with debugging (Bug#12118).
2500 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
2501 ARRAY_MARK_FLAG when checking subscripts, because ASET is
2502 not supposed to be invoked from the garbage collector.
2503 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
2504 (gc_aset): New function, which is like ASET but can be
2505 used in the garbage collector.

2521 headers (most versions of MinGW w32api don't).
2522 (get_security_info, create_symbolic_link)
2523 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

2530 have the required privileges.
2531 (get_file_security_desc_by_name): Rename from
2532 get_file_security_desc.
2533 (stat_worker): New function, with most of the guts of 'stat', and
2534 with addition of handling of symlinks and support for 'lstat'.
2535 If possible, get file's attributes and security information by
2536 handle, not by name. Produce S_IFLNK bit for symlinks, when
2537 called from 'lstat'.
2538 (stat, lstat): New functions, call 'stat_worker'.
2539 (symlink, readlink, careadlinkat): Rewritten to create and resolve
2540 symlinks when the underlying filesystem supports them.
2542 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
2544 Fix macroexp crash on Windows with debugging (Bug#12118).
2545 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
2546 checking subscripts; problem introduced with the recent
2547 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
2548 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
2549 since it's used in non-static inline functions now.
2551 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
2552 Don't assume buffer size fits in 'int'. Remove unused local.

2570 * character.c (CHARACTER_INLINE):
2571 * charset.c (CHARSET_INLINE):
2572 * composite.c (COMPOSITE_INLINE):
2573 * dispnew.c (DISPEXTERN_INLINE):
2574 * sysdep.c (SYSTIME_INLINE):
2575 Define to EXTERN_INLINE, so that the corresponding functions
2576 are compiled into code.
2577 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
2578 (INLINE_HEADER_END): New macros.
2579 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

2599 hard-coding the path separator.
2601 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
2603 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
2604 This how ASET and AREF are supposed to work, and makes
2605 it easier to think about future improvements. See
2606 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
2607 * charset.h (set_charset_attr): New function.

3099 the fix for 12036 would have avoided some of the problems noted in
3100 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
3101 would have been more obvious.

3111 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3112 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3113 not be usable in #if. This simplifies things.
3115 2012-07-26 Juanma Barranquero <lekktu@gmail.com>

3122 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3123 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3124 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3125 Adjust to changes in lisp.h and emacs.c, by using
3126 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead

4037 * nsterm.m (ns_term_init):
4038 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4039 * nsterm.m (ns_term_init):
4040 Avoid the need for strncpy, by using build_string or
4041 make_unibyte_string directly. Use dtoastr, not snprintf.
4042 * process.c (Fmake_network_process): Diagnose service names that
4043 are too long, rather than silently truncating them or creating
4044 non-null-terminated names.
4045 (Fnetwork_interface_info): Likewise, for interface names.
4046 * sysdep.c (system_process_attributes) [GNU_LINUX]:
4047 Prefer sprintf to strncat.
4048 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

4074 Optimize pure C strings initialization.
4075 * lisp.h (make_pure_string): Fix prototype.
4076 (build_pure_c_string): New function, defined as static inline. This
4077 provides a better opportunity to optimize away calls to strlen when
4078 the function is called with compile-time constant argument.
4079 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
4080 argument, adjust users accordingly. Use build_pure_c_string where
4082 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
4083 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
4084 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
4086 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4088 Avoid calls to strlen in miscellaneous functions.
4089 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
4090 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
4091 * lread.c (openp): Likewise.
4093 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4095 Avoid calls to strlen in path processing functions.
4096 * fileio.c (file_name_as_directory): Add comment. Change to add
4097 srclen argument and return the length of result. Adjust users
4099 (directory_file_name): Fix comment. Change to add srclen argument,
4100 swap 1st and 2nd arguments to obey the common convention.
4101 Adjust users accordingly.
4102 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
4104 2012-07-10 Glenn Morris <rgm@gnu.org>
4106 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

4111 * s/gnu.h (DATA_START): Move definitions to configure.
4113 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
4114 We include usg5-4-common.h, which defines them both.
4116 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
4117 O_RDONLY already includes it).
4119 Stop ns builds setting the EMACSLOADPATH environment variable.
4120 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4121 Now it does not set EMACSLOADPATH, just returns the load-path string.
4122 * nsterm.h: Update accordingly.
4123 * lread.c [HAVE_NS]: Include nsterm.h.
4124 (init_lread) [HAVE_NS]: Use ns_load_path.

4127 2012-07-09 Glenn Morris <rgm@gnu.org>
4129 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
4130 since the included bsd-common.h does so.
4132 Stop ns builds setting the EMACSPATH environment variable.
4133 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
4134 (ns_init_paths): Do not set EMACSPATH.
4135 * nsterm.h (ns_exec_path): Add it.
4136 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
4139 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
4141 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
4143 * process.c (wait_reading_process_output): 'waitchannels' was unset
4144 when read_kbd || !NILP (wait_for_cell); fix this.
4146 Add GCC-style 'const' attribute to functions that can use it.
4147 * character.h (char_resolve_modifier_mask):
4148 * keyboard.h (make_ctrl_char):
4149 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

4156 Declare the dummy function with ATTRIBUTE_CONST.
4157 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
4158 Add decls with ATTRIBUTE_CONST.
4160 Minor improvements to make_formatted_string.
4161 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
4162 where int is good enough, as vsprintf returns an int.
4163 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
4165 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4167 Use make_formatted_string to avoid double length calculation.
4168 * lisp.h (make_formatted_string): New prototype.
4169 * alloc.c (make_formatted_string): New function.
4170 * buffer.c (Fgenerate_new_buffer_name): Use it.

4174 * frame.c (make_terminal_frame, set_term_frame_name)
4175 (x_report_frame_params): Likewise.
4176 * image.c (gs_load): Likewise.
4177 * minibuf.c (get_minibuffer): Likewise.

4192 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4194 Move marker debugging code under MARKER_DEBUG.
4195 * marker.c (MARKER_DEBUG): Move marker debugging code under
4196 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4197 for bootstrap with --enable-checking (~3x slowdown reported
4198 by Juanma Barranquero <lekktu@gmail.com>).
4199 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4201 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4203 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
4204 See <http://bugs.gnu.org/11825#29>.
4206 2012-07-08 Eli Zaretskii <eliz@gnu.org>
4208 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4209 has no font, use the frame's font. (Bug#11813)
4210 (display_line): Add commentary about displaying truncation glyphs
4212 (produce_special_glyphs): Move here from term.c.
4214 * term.c (produce_special_glyphs): Move to xdisp.c.
4216 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4219 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4221 * xdisp.c (display_line): Avoid warning about implicit declaration
4224 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4226 * lisp.h: Remove empty conditional.
4228 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4230 * lread.c (load_path_check): Now static.
4232 Fix some minor --with-ns problems found by static checking.
4233 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
4234 (x_set_font) [!HAVE_X_WINDOWS]:
4235 * image.c (xpm_load_image) [HAVE_NS]:
4236 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4237 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4238 Remove unused local.
4239 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
4240 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
4241 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
4242 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
4243 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
4244 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
4245 Fix pointer signedness problem.
4246 * xfaces.c (FRAME_X_FONT_TABLE):
4247 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
4249 2012-07-07 Glenn Morris <rgm@gnu.org>
4251 * lread.c (load_path_check): New function, split from init_lread.
4252 (init_lread): Reorganize. Motivation:
4253 If EMACSLOADPATH is set, check/warn about that rather than the
4254 defaults, which we are not going to use. Hence we can remove
4255 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4256 Don't warn if site-lisp directories are missing.
4257 If not installed, start from a blank load-path, since
4258 PATH_LOADSEARCH refers to the eventual installation directories.
4260 2012-07-07 Eli Zaretskii <eliz@gnu.org>
4262 Support truncation and continuation glyphs on GUI frames, when
4263 fringes are disabled. (Bug#11832)
4264 * xdisp.c (init_iterator): Get dimensions of truncation and
4265 continuation glyphs even if on GUI frames.
4266 Adjust it->last_visible_x on GUI frames when the left or right fringes,
4267 or both, are absent.
4268 (start_display, move_it_in_display_line_to): Handle the case of a
4269 GUI frame without a fringe to display continuation or truncation
4271 (insert_left_trunc_glyphs): Support GUI frames: make sure
4272 truncation glyphs overwrite enough glyphs from the current line to
4273 have sufficient space in pixels.
4274 (display_line): Support truncation and continuation glyphs on GUI
4275 frames. If some spare pixels are left on the line after inserting
4276 the truncation glyphs, fill that space with a stretch glyph of a
4277 suitably computed width.
4279 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4280 produce_glyphs, to support GUI sessions.
4282 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4284 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4286 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4288 Do not require float-time's arg to fit in time_t (Bug#11825).
4289 This works better on hosts where time_t is unsigned, and where
4290 float-time is applied to the (negative) difference between two times.
4291 * editfns.c (decode_time_components): Last arg is now double *,
4292 not int *, and means to store all the result as a double, without
4293 worrying about whether the seconds part fits in time_t.
4294 All callers changed.
4295 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4296 All callers changed.
4297 (Ffloat_time): Do not fail merely because the specified time falls
4298 outside of time_t range.
4300 2012-07-07 Glenn Morris <rgm@gnu.org>
4302 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

4308 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
4309 Update dependencies.
4311 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
4313 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4315 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

4317 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
4318 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
4319 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
4320 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
4322 * xfont.c (compare_font_names): Redo to omit the need for casts.
4324 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4326 * xfns.c (Fx_change_window_property): Doc fix.
4327 * w32fns.c (Fx_change_window_property): Doc fix.
4329 * w32fns.c (Fx_window_property): Accept the same arguments as the
4330 X Windows version. Doc fix.
4331 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4333 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4334 Eli Zaretskii <eliz@gnu.org>
4336 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4337 Windows-specific code from nt/config.nt moved here.
4338 Obsolete settings removed.
4340 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4342 * process.c: Avoid unnecessary calls to gettime.
4343 (wait_reading_process_output): Don't get the time of day
4344 when gobbling data immediately and not waiting, as there's no need
4345 for it in that case. This removes a FIXME.
4347 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4349 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4350 is defined (Bug#11768).
4352 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4354 Fix marker debugging code.
4355 * marker.c (byte_char_debug_check): Do not perform the check
4356 if buffer is not multibyte.
4357 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4358 Call byte_char_debug_check with correct arguments.
4360 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4362 Compile marker debugging code only if ENABLE_CHECKING is defined.
4363 * marker.c (byte_char_debug_check, count_markers):
4364 Use only if ENABLE_CHECKING is defined.
4365 (byte_debug_flag): Remove.
4366 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4367 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4369 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4371 Avoid code repetition in marker-related functions.
4372 * marker.c (attach_marker): New function.
4373 (Fset_marker, set_marker_restricted, set_marker_both)
4374 (set_marker_restricted_both): Use it.
4375 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4376 Consistently rename charno to charpos.
4377 (marker_position): Add eassert.
4378 (marker_byte_position): Convert to eassert.

4397 * window.c (save_window_save): Likewise.
4399 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4401 Do not use Fdelete_overlay in delete_all_overlays
4402 to avoid redundant calls to unchain_overlay.
4403 * buffer.c (drop_overlay): New function.
4404 (delete_all_overlays, Fdelete_overlay): Use it.
4405 * minibuf.c (get_minibuffer): Fix comment.
4407 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4409 Port to OpenBSD 5.1 amd64.
4410 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4411 This is needed for OpenBSD, and should be harmless on all BSD systems.
4412 Also, include <sys/sysctl.h>, as it should be available on all
4413 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4414 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4415 use p_pid member, not kp_proc.pid.
4417 2012-07-06 Glenn Morris <rgm@gnu.org>
4419 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4421 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4423 More xmalloc and related cleanup.
4424 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
4425 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
4426 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
4427 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
4428 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
4429 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
4430 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
4431 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
4432 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4434 Omit needless casts involving void * pointers and allocation.
4435 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4436 as the former is more robust if P's type is changed.
4437 Prefer xzalloc to xmalloc + memset 0.
4438 Simplify malloc-or-realloc to realloc.
4439 Don't worry about xmalloc returning a null pointer.
4440 Prefer xstrdup to xmalloc + strcpy.
4441 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4443 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4444 alloca of a constant.
4446 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4448 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4449 hscroll is larger than the line width. Fixes long and futile
4450 looping inside extend_face_to_end_of_line (on a TTY) producing
4451 glyphs that are not needed and thrown away.
4453 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4455 * marker.c (set_marker_restricted_both): Simplify by using
4458 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4460 * editfns.c (region_limit): Simplify by using clip_to_bounds.

4469 followed by gtk_box_set_homogeneous (Bug#11768).
4470 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4471 (update_theme_scrollbar_width, xg_create_scroll_bar):
4472 Use gtk_scrollbar_new (Bug#11768).
4473 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

4481 * xdisp.c (window_hscroll_limited): New function.
4482 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
4483 coordinates when window's hscroll is set to insanely large
4486 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
4488 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
4489 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
4491 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4494 * lisp.h (xzalloc): New prototype. Omit needless casts.

4549 * fileio.c (time_error_value): Check the right error number.
4550 Problem reported by Troels Nielsen in
4551 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
4553 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4555 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
4556 This should be fixed in a better way; see Eli Zaretskii in
4557 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
4558 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
4560 * fileio.c (time_error_value): Rename from special_mtime.
4561 The old name's problems were noted by Eli Zaretskii in
4562 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
4564 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
4565 This variable's comment says Emacs needs at least one GDB-visible
4566 symbol of type enum pvec_type, to work around GDB problems.
4567 The symbol's value doesn't matter.
4569 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
4570 that causes compilation to fail on pre-C99 compilers.
4572 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
4574 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
4575 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
4577 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4579 * buffer.c (init_buffer_once): Fix initialization of
4580 headers for buffer_defaults and buffer_local_symbols.
4581 Reported by Juanma Barranquero <lekktu@gmail.com>.
4583 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
4585 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
4586 * lisp.h (enum pvec_type): Use fewer bits.
4587 (PSEUDOVECTOR_SIZE_BITS): New constant.
4588 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
4589 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
4590 change in pvec_type.
4591 (PSEUDOVECTOR_TYPEP): New macro.
4592 (TYPED_PSEUDOVECTORP): Use it.
4593 * fns.c (internal_equal): Adapt code to extract pvectype.

4595 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
4596 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
4597 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
4598 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
4599 (sweep_vectors): Use it. Use local var `total_bytes' instead of
4600 abusing vector->header.next.nbytes.
4601 (live_vector_p): Use PVEC_TYPE.
4602 (mark_object): Adapt code to extract pvectype. Use switch.
4604 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4606 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
4607 Tighten new eassert a bit.
4609 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4611 Fix compilation with --enable-gcc-warnings and -O1
4613 * doprnt.c (doprnt): Change type of tem to int, initialize
4614 to avoid compiler warning. Add eassert.
4615 * search.c (simple_search): Initialize match_byte to avoid
4616 compiler warning. Add eassert.
4618 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4620 Avoid weird behavior with large horizontal scrolls.
4621 Without this change, for example, large hscroll values would
4622 mess up Emacs's display on Fedora 15 x86, presumably due to
4623 overflows in int calculations in the display code.
4624 Also, if buffers had long lines, Emacs would freeze.
4625 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
4626 (set_window_hscroll): New function, containing the old guts of
4627 Fset_window_hscroll. Return the clipped value.
4628 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
4629 This avoids the need to check against PTRDIFF_MAX.
4631 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
4633 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4635 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
4637 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4639 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
4640 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
4641 since GCC 4.4.6 issues a bogus warning for them.
4643 Fix bugs in file timestamp newness comparisons.
4644 * fileio.c (Ffile_newer_than_file_p):
4645 * lread.c (Fload): Use full timestamp resolution of files,
4646 not just the 1-second resolution, so that files that are only
4647 slightly newer still count as newer.
4648 * fileio.c (Ffile_newer_than_file_p): Don't assume file
4649 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
4651 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
4653 * fileio.c: Improve handling of file time marker. (Bug#11852)
4654 (special_mtime): New function.
4655 (Finsert_file_contents, Fverify_visited_file_modtime):
4656 Use it to set special mtime values consistently.
4658 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
4660 * fileio.c (Finsert_file_contents): Properly handle st_mtime
4661 marker for non-existing file. (Bug#11852)
4663 2012-07-03 Glenn Morris <rgm@gnu.org>
4665 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
4666 and did not make it into globals.h).
4668 2012-07-03 Tom Tromey <tromey@redhat.com>
4670 * window.c (Fset_window_margins, Fset_window_fringes)
4671 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
4672 * textprop.c (Fprevious_property_change): No longer static.
4673 * syntax.c (Fsyntax_table_p): No longer static.

4695 * intervals.h: Remove EXFUNs.
4696 * fontset.h: Remove EXFUN.

4704 * xterm.h: Remove EXFUN.
4706 2012-07-03 Glenn Morris <rgm@gnu.org>
4708 * lisp.h (Frandom): Make it visible to C.
4709 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
4710 buffer for invisible buffers. (Bug#1229)
4712 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4714 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
4715 values which aren't power of 2.
4716 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
4717 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
4720 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
4722 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
4724 * alloc.c (mark_object): Revert part of last patch to use `switch'.
4726 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4728 * alloc.c (allocate_vector_block): Remove redundant
4729 calls to mallopt if DOUG_LEA_MALLOC is defined.
4730 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
4731 avoid calls to mallopt if zero_vector is returned.
4733 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4735 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
4736 is enabled, avoid dereferencing NULL current_sblock if
4739 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4741 Cleanup basic buffer management.
4742 * buffer.h (struct buffer): Change layout to use generic vector
4743 marking code. Fix some comments. Change type of 'clip_changed'
4744 to bitfield. Remove unused #ifndef old.
4745 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
4746 (GET_OVERLAYS_AT): Fix indentation.
4747 (for_each_per_buffer_object_at): New macro.

4751 * alloc.c (allocate_buffer): Adjust to match new layout of
4752 struct buffer. Fix comment.
4753 (mark_overlay): New function.

4756 (mark_object): Use it. Adjust marking of misc objects
4757 and related comments.
4759 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
4761 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
4762 wrapper that is not needed because the wrapped code is a no-op (zero
4763 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
4764 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
4766 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
4768 * alloc.c (mark_buffer): Simplify. Remove prototype.
4769 (mark_object): Add comment. Reorganize marking of vector-like
4770 objects. Use CHECK_LIVE for all vector-like objects except buffers
4771 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
4772 Avoid redundant calls to mark_vectorlike for bool vectors.
4774 2012-06-30 Glenn Morris <rgm@gnu.org>
4776 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
4778 * epaths.in (PATH_SITELOADSEARCH): New.
4779 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
4780 This is rather than relying on --enable-locallisppath elements
4781 having "site-lisp" in their names. (Bug#10208#25, 11658)
4783 2012-06-30 Eli Zaretskii <eliz@gnu.org>
4785 * w32proc.c (sys_select): Accept and ignore one more argument.
4787 * w32.c (emacs_gnutls_pull): Call select with one more argument.
4789 * sysselect.h [DOS_NT]: Don't include sys/select.h.
4790 (pselect) [!MS_DOS]: Redirect to sys_select.
4792 * sysdep.c: Don't include dos.h and dosfns.h.
4794 * process.c (sys_select):
4795 * msdos.c (sys_select): Accept one more argument and ignore it.
4797 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
4798 adapt data types and code to that.
4801 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
4802 which clashes with the gnulib function of the same name.
4804 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
4806 * font.c (font_style_to_value, font_style_symbolic)
4807 (font_prop_validate_style): Add type checks for values in
4810 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
4812 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
4815 2012-06-29 Eli Zaretskii <eliz@gnu.org>
4817 * xdisp.c (try_window_id): Undo last change.
4819 * w32.c (getwd): Adjust commentary about startup_dir.
4820 (init_environment): Always call sys_access, even in non-MSVC
4821 builds. Don't chdir to the directory of the Emacs executable.
4822 This undoes code from 1997 which was justified by the need to
4823 "avoid conflicts when removing and renaming directories". But its
4824 downside was that every relative file name was being interpreted
4825 relative to the directory of the Emacs executable, which can never
4826 be TRT. In particular, it broke sys_access when called with
4827 relative file names.
4828 (sys_access): Map GetLastError to errno.
4830 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4832 * window.h (struct window): Change type of 'fringes_outside_margins'

4836 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
4839 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
4841 * gnutls.c (emacs_gnutls_handshake):
4842 Add QUIT to make the loop interruptible.
4844 2012-06-29 Glenn Morris <rgm@gnu.org>
4846 * charset.c (init_charset): Make lack of etc/charsets fatal.
4848 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4850 * editfns.c (region_limit): Fix type mismatch.
4852 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4854 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
4855 undefined. Convert from xassert to eassert.
4856 * nsmenu.m: Convert from xassert to eassert.
4857 * nsterm.m: Likewise.
4859 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
4861 * editfns.c (region_limit): Clip to narrowing (bug#11770).
4863 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
4865 Avoid integer overflow on scroll-left and scroll-right.
4866 * window.c (HSCROLL_MAX): New macro.
4867 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
4868 overflow when requested scroll falls outside ptrdiff_t range.
4870 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
4872 * window.h (struct window): Change type of 'hscroll',
4873 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
4874 'last_modified' and 'last_overlay_modified' to EMACS_INT.
4875 Adjust users accordingly.
4876 * xdisp.c (try_cursor_movement): Replace type check with eassert.
4877 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
4878 from EMACS_INT to ptrdiff_t.
4879 (make_window): Omit redundant initialization.
4881 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
4883 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
4885 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
4887 * window.h (struct window): Change type of 'use_time' and
4888 'sequence_number' from Lisp_Object to int.

4897 enabled with --enable-checking=[all,glyphs] configure option.
4898 Fix GLYPH_DEBUG usage assuming that it may be undefined,
4899 adjust comments accordingly.

4950 avoid GCC warning about unused macro.
4952 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
4954 * alloc.c (allocate_string): Omit intervals initialization.
4955 * alloc.c (make_uninit_multibyte_string): Initialize intervals
4956 as in make_pure_string and make_pure_c_string.
4958 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
4960 * alloc.c (allocate_string): Fix last change.
4962 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

4981 when building with Clang.
4983 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>

5012 * alloc.c: Remove build_string.
5013 * lisp.h: Define build_string as static inline. This provides
5014 a better opportunity to optimize away calls to strlen when the
5015 function is called with compile-time constant argument.
5016 * image.c (imagemagick_error): Convert to build_string.
5017 * w32proc.c (sys_spawnve): Likewise.
5018 * xterm.c (x_term_init): Likewise.
5020 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
5022 Use sprintf return value instead of invoking strlen on result.
5023 In the old days this wasn't portable, since some sprintf
5024 implementations returned char *. But they died out years ago and
5025 Emacs already assumes sprintf returns int.
5026 Similarly for float_to_string.
5027 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
5028 * ccl.c (ccl_driver):
5029 * character.c (string_escape_byte8):

5032 * print.c (print_object):
5033 * xdisp.c (message_dolog):
5034 * xfns.c (syms_of_xfns):
5035 Use sprintf or float_to_string result to avoid need to call strlen.
5036 * data.c (Fnumber_to_string):
5037 Use make_unibyte_string, since the string must be ASCII.
5038 * lisp.h, print.c (float_to_string): Now returns int length.
5039 * term.c (produce_glyphless_glyph):
5040 Use sprintf result rather than recomputing it.
5042 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
5043 * Makefile.in (ALL_CFLAGS):
5044 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
5045 * gmalloc.c, regex.c: Include <config.h> unconditionally.
5047 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
5049 * dispextern.h (xstrcasecmp): Define to library function
5050 strcasecmp if available.
5051 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
5053 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>

5066 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
5068 * gtkutil.c (get_utf8_string): Remove redundant assignment.
5069 sprintf already null-terminates its output.
5071 * xfns.c (x_window): Remove redundant cast.
5073 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
5075 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
5076 `const char *' to `char *' to avoid compiler warning.
5078 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
5080 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
5081 instead of truncating it to 63 (admittedly a generous limit).
5083 * process.c: Fix spelling and caps in comments.
5085 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
5087 * emacs.c (setpgrp): Remove definition, unused.

5131 Use _Noreturn rather than NO_RETURN.
5132 No need for separate decl merely because of _Noreturn.
5133 * sound.c (sound_warning, parse_sound):
5134 Remove unnecessary forward decls.
5136 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
5138 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
5139 * lisp.h (WAIT_READING_MAX): New macro.
5140 * dispnew.c (Fsleep_for, sit_for):
5141 * keyboard.c (kbd_buffer_get_event):
5142 * process.c (Faccept_process_output):
5143 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
5144 This improves on the previous patch, which introduced a bug
5145 when time_t is unsigned and as wide as intmax_t.
5146 See <http://bugs.gnu.org/9000#51>.
5148 2012-06-23 Eli Zaretskii <eliz@gnu.org>
5150 * dispnew.c (sit_for, Fsleep_for):
5151 * keyboard.c (kbd_buffer_get_event):

5164 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
5165 Privately reported by Herbert J. Skuhra.
5166 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
5168 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
5169 not make_lisp_timeval, when the argument is of type EMACS_TIME.
5171 2012-06-23 Eli Zaretskii <eliz@gnu.org>
5173 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
5174 last argument of make_unibyte_string.
5176 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
5177 language ID in the event parameters.
5179 * w32term.c (w32_read_socket): Put the new keyboard codepage into
5180 event.code, not the obscure "character set ID".
5182 2012-06-23 Chong Yidong <cyd@gnu.org>
5184 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
5186 2012-06-23 Eli Zaretskii <eliz@gnu.org>
5188 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

5203 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
5204 Privately reported by Herbert J. Skuhra.
5205 [__FreeBSD__]: Remove "*/" typo after "#include".

5209 Don't assume EMACS_TIME and struct timeval are the same type.
5211 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5213 Support higher-resolution time stamps (Bug#9000).
5214 The time stamps are only nanosecond-resolution at the C level,
5215 since that's the best that any real-world system supports now.
5216 But they are picosecond-resolution at the Lisp level, as that's
5217 easy, and leaves room for future OS improvements.
5219 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5222 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5223 Don't get current time unless it's needed.
5225 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5226 now provides it if it's absent.
5227 (start_atimer): Port to higher-res time stamps.
5228 Check for time stamp overflow. Don't get current time more
5229 often than is needed.
5231 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5232 Include systime.h, not time.h.
5233 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
5235 * dired.c: Include stat-time.h.
5236 (Ffile-attributes): File times now have higher resolution.
5238 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
5239 (struct image): Timestamp now has higher resolution.
5241 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5242 has at least microseconds now. All uses removed.
5243 (update_frame, update_single_window, update_window, update_frame_1)
5244 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5245 (duration_to_sec_usec): Remove; no longer needed.
5247 * editfns.c (time_overflow): Now extern.
5248 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
5249 (float-time, Fformat_time_string, Fcurrent_time_string)
5250 (Fcurrent_time_zone): Accept and generate higher-resolution
5252 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
5253 (decode_time_components, lisp_seconds_argument): New functions.
5254 (make_time): Now static.
5255 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
5256 Report an error if the time is invalid, rather than having the caller
5259 * fileio.c: Include <stat-time.h>
5260 (Fcopy_file): Copy higher-resolution time stamps.
5261 Prefer to set the time stamp via a file descriptor if that works.
5262 (Fset_file_times, Finsert_file_contents, Fwrite_region)
5263 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
5264 (Fvisited_file_modtime, Fset_visited_file_modtime):
5265 Support higher-resolution time stamps.
5267 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
5269 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
5271 * image.c (prepare_image_for_display, clear_image_cache)
5272 (lookup_image): Port to higer-resolution time stamps.
5274 * keyboard.c (start_polling, bind_polling_period):
5275 Check for time stamp overflow.
5276 (read_char, kbd_buffer_get_event, timer_start_idle)
5277 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
5278 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5279 Port to higher-resolution time stamps. Do not assume time_t is signed.
5280 (decode_timer): New function. Timers are now vectors of length 9,
5281 not 8, to accommodate the picosecond component.
5282 (timer_check_2): Use it.
5284 * nsterm.m (select_timeout, timeval_subtract): Remove.
5285 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5286 as they're a bit more accurate and handle overflow better.
5287 (ns_select): Change prototype to be compatible with pselect.
5288 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5289 * nsterm.h (ns_select): Adjust prototype.
5291 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5292 us-resolution time stamps.
5293 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5295 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5297 * lisp.h (time_overflow): New decl.
5298 (wait_reading_process_output): First arg is now intmax_t, not int,
5299 to accommodate larger waits.
5301 * process.h (struct Lisp_Process.read_output_delay):
5302 Now counts nanoseconds, not microseconds.
5303 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
5305 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
5306 (wait_reading_process_output):
5307 Port to ns-resolution time stamps.
5308 (Faccept_process_output, wait_reading_process_output):
5309 Check for time stamp overflow. Do not assume time_t is signed.
5310 (select_wrapper): Remove; we now use pselect.
5311 (Fprocess_attributes): Now generates ns-resolution time stamps.
5313 * sysdep.c: Include utimens.h. Don't include utime.h
5314 or worry about struct utimbuf; gnulib does that for us now.
5315 (gettimeofday): Remove; gnulib provides a substitute.
5316 (make_timeval): New function.
5317 (set_file_times): Now sets ns-resolution time stamps.
5318 New arg FD; all uses changed.
5319 (time_from_jiffies, ltime_from_jiffies, get_up_time)
5320 (system_process_attributes):
5321 Now returns ns-resolution time stamp. All uses changed.
5322 Check for time stamp overflow.
5324 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5325 provides a substitute now.
5327 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5328 since it guarantees struct timespec.
5329 (EMACS_TIME): Now struct timespec, so that we can support
5330 ns-resolution time stamps.
5331 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5332 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5333 (EMACS_USECS): Remove.
5334 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5335 so multiply the arg by 1000 before storing it.
5336 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
5338 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
5339 Port to ns-resolution time stamps.
5340 (EMACS_TIME_NEG_P): Remove; replaced by....
5341 (EMACS_TIME_SIGN): New macro.
5342 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
5343 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
5344 (set_file_times, make_time, lisp_time_argument): Adjust signature.
5345 (make_timeval, make_lisp_time, decode_time_components): New decls.
5346 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
5347 that it mishandled time_t overflow. You can't compare by subtracting!
5348 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
5349 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
5351 * term.c: Include <sys/time.h>.
5352 (timeval_to_Time): New function, for proper overflow wraparound.
5353 (term_mouse_position, term_mouse_click): Use it.
5355 * undo.c (record_first_change): Support higher-resolution time stamps
5357 (Fprimitive_undo): Use them when restoring time stamps.
5359 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
5360 (w32_get_internal_run_time):
5361 Port to higher-resolution Emacs time stamps.
5362 (ltime): Now accepts single 64-bit integer, as that's more convenient
5365 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
5367 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
5368 for compatibility with pselect. Support ns-resolution time stamps.
5370 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
5372 * xselect.c (wait_for_property_change, x_get_foreign_selection):
5373 Check for time stamp overflow, and support ns-resolution time stamps.
5375 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
5376 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
5377 (timeval_subtract): Remove; no longer needed.
5378 (XTflash, XTring_bell, x_wait_for_event):
5379 Port to ns-resolution time stamps. Don't assume time_t is signed.
5381 2012-06-22 Chong Yidong <cyd@gnu.org>
5383 * xdisp.c (x_consider_frame_title): Revert last change.
5385 2012-06-22 Eli Zaretskii <eliz@gnu.org>
5387 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
5388 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5389 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
5390 staticidx goes up to 1597 out of 1600 = 0x640.)
5392 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
5394 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
5395 Otherwise, the umask might be mistakenly 0 while handling input signals.
5397 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
5399 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

5404 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
5405 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
5406 access to `contents' member of Lisp_Vector objects with AREF and ASET
5409 2012-06-19 Chong Yidong <cyd@gnu.org>
5411 * frame.c (delete_frame): When selecting a frame on a different
5412 text terminal, do not alter the terminal's top-frame.

5415 frame's selected window and its terminal's top-frame.
5416 (unwind_format_mode_line): Restore them.
5417 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
5419 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
5420 since tty frames can be explicitly named.
5421 (prepare_menu_bars): Likewise.
5423 * term.c (Ftty_top_frame): New function.
5425 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
5427 Port byte-code-meter to modern targets.
5428 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
5429 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
5430 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
5431 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
5432 (METER_1, METER_2): Simplify.
5434 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
5436 * data.c (Fdefalias): Return `symbol' (bug#11686).
5438 2012-06-18 Martin Rudalics <rudalics@gmx.at>
5440 * buffer.c (Fkill_buffer): Don't throw an error when the buffer

5664 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
5665 Use an inline function on all platforms when using the union type,
5666 since this is simpler and 'static inline' can be used portably

5810 * doprnt.c (doprnt): Truncate multibyte char correctly.
5811 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
5812 would mishandle a string argument "Xc" if X was a multibyte

5897 and 'double' in a couple of places.

5901 * xdisp.c (handle_stop): Detect whether we have overlay strings
5902 loaded by testing it->current.overlay_string_index to be
5903 non-negative, instead of checking whether n_overlay_strings is
5904 positive. (Bug#11587)

5922 for the duration of call to load_charset, to avoid problems with
5923 callers of maybe_unify_char that access buffer text through C
5926 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
5927 decrement the inhibition flag, instead of just setting or
5930 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5932 Remove obsolete '#define static' cruft.
5933 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
5934 This #undef was "temporary" in 2000; it is no longer needed
5935 now that '#define static' has gone away.
5936 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
5937 (gray_bitmap_bits): Remove; no longer needed.
5938 All uses replaced with definiens.
5939 * xterm.c: Include "bitmaps/gray.xbm".
5941 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
5943 Clean up __executable_start, monstartup when --enable-profiling.
5944 The following changes affect the code only when profiling.
5945 * dispnew.c (__executable_start): Rename from safe_bcopy.
5946 Define only on platforms that need it.
5947 * emacs.c: Include <sys/gmon.h> when profiling.
5948 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
5949 (__executable_start): Remove decl, since lisp.h does it now.
5950 (safe_bcopy): Remove decl; no longer has that name.
5951 (main): Coalesce #if into single bit of code, for simplicity.
5952 Cast pointers to uintptr_t, since standard libraries want integers
5954 * lisp.h (__executable_start): New decl.
5956 2012-05-31 Glenn Morris <rgm@gnu.org>
5958 * image.c (Fimagemagick_types): Doc fix.
5960 2012-05-30 Jim Meyering <meyering@redhat.com>
5962 * callproc.c (Fcall_process_region): Include directory component
5963 in mkstemp error message (Bug#11586).

5974 * data.c (Fdefalias): Purify definition, except for keymaps.
5975 (Qdefun): Move from eval.c.
5976 * lisp.h (Qdefun): Remove.
5977 * lread.c (read1): Tiny simplification.
5979 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
5981 Do not create empty overlays with the evaporate property (Bug#9642).
5982 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
5983 Bug#9642, but explicitly check that the buffer the overlay would
5984 be moved to is live and rearrange lines to make sure that errors
5985 will not put the overlay in an inconsistent state.
5986 (Fdelete_overlay): Cosmetics.
5988 2012-05-28 Eli Zaretskii <eliz@gnu.org>
5990 * w32term.c (my_bring_window_to_top): New function.
5991 (x_raise_frame): Use handle returned by DeferWindowPos, which
5992 could be different from the original one.

5996 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
5997 by calling BringWindowToTop.
5999 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6000 (WM_EMACS_END): Increase by one.
6002 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6004 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6005 This avoids undefined behavior that might cause the eassert
6006 to not catch an out-of-range value.
6008 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6010 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
6011 Update dependencies.
6013 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6015 * bidi.c (bidi_mirror_char): Fix last change.
6017 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
6019 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
6020 when referring to sectname field in printf format.
6022 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
6024 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6025 Only r_alloc_inhibit_buffer_relocation needed to be added;
6026 the others were already declared.
6028 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6029 before checking whether it's out of range. Put the check inside
6031 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6033 2012-05-27 Ken Brown <kbrown@cornell.edu>
6035 * callproc.c (Fcall_process): Restore a line that was accidentally
6036 commented out in the 2011-02-13 change (bug#11547).
6038 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6040 * lisp.h [REL_ALLOC]: Add prototypes for external functions
6041 defined on ralloc.c.
6043 * buffer.c [REL_ALLOC]: Remove prototypes of
6044 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
6045 they are now on lisp.h.
6047 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6049 * search.c (search_buffer): Use it to inhibit relocation of buffer
6050 text while re_search_2 is doing its job, because re_search_2 is
6051 passed C pointers to buffer text. (Bug#11519)
6053 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6056 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6057 state after an additional call to move_it_in_display_line_to, keep
6058 the values of it->max_ascent and it->max_descent found for the
6060 (pos_visible_p): Revert the comparison against bottom_y to what it
6061 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
6064 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6066 Fix coding-related core dumps with gcc -ftrapv.
6067 The code was computing A - B, where A and B are pointers, and B is
6068 random garbage. This can lead to core dumps on platforms that
6069 have special pointer registers, and it also leads to core dumps on
6070 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6071 A - B only when B is initialized properly.
6072 * coding.c (coding_set_source, coding_set_destination): Return void.
6073 (coding_change_source, coding_change_destinations): New functions,
6074 with the old behaviors of coding_set_source and coding_set_destination.
6075 All callers that need an offset changed to use these new functions.
6077 2012-05-26 Glenn Morris <rgm@gnu.org>
6079 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
6081 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6083 Extend mouse support on W32 text-mode console.
6084 * xdisp.c (draw_row_with_mouse_face):
6085 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6087 * w32console.c: Include window.h.
6088 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6090 (initialize_w32_display): Initialize mouse-highlight data.
6092 * w32inevt.c: Include termchar.h and window.h.
6093 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6094 moves, call note_mouse_highlight. If help_echo changed, call
6095 gen_help_event to produce help-echo message in the echo area.
6096 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6099 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6101 * lread.c (read1): Simplify slightly to avoid an overflow warning
6102 with GCC 4.7.0 on x86-64.
6104 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6106 * bidi.c (bidi_mirror_char): Revert last change: an int is
6107 definitely wide enough here.
6109 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
6111 Fix integer width and related bugs (Bug#9874).
6112 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
6113 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
6114 (string_bytes, check_sblock, allocate_string_data):

6118 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
6119 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
6121 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6122 (allocate_pseudovector):
6123 Use int, not EMACS_INT, where int is wide enough.
6124 (inhibit_garbage_collection, Fgarbage_collect):
6125 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6126 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
6127 int might not be wide enough.
6128 (bidi_cache_search, bidi_cache_find, bidi_init_it)
6129 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)

6131 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
6132 (bidi_level_of_next_char, bidi_move_to_visually_next):
6133 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6134 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
6135 (Fkill_buffer, Fset_buffer_major_mode)
6136 (advance_to_char_boundary, Fbuffer_swap_text)

6139 (overlay_strings, recenter_overlay_lists)
6140 (adjust_overlays_for_insert, adjust_overlays_for_delete)
6141 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
6142 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
6143 (Foverlay_recenter, last_overlay_modification_hooks_used)
6144 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6145 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6146 (validate_region): Omit unnecessary test for b <= e,
6147 since that's guaranteed by the previous test.
6148 (adjust_overlays_for_delete): Avoid pos + length overflow.
6149 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6150 (report_overlay_modification):
6151 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6152 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
6153 Omit pointer cast, which isn't needed anyway, and doesn't work
6154 after the EMACS_INT -> ptrdiff_t change.
6155 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
6156 * buffer.h: Adjust decls to match defn changes elsewhere.

6160 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
6161 not int, to avoid needless 32-bit limit on 64-bit hosts.
6162 (exec_byte_code): Use tighter memory-full test, one that checks
6163 for alloca overflow. Don't compute the address of the object just
6164 before an array, as that's not portable. Use EMACS_INT, not
6165 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
6166 * callint.c (Fcall_interactively):
6167 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6168 * callproc.c (call_process_kill, Fcall_process):
6169 Don't assume pid_t fits into an Emacs fixnum.

6178 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
6179 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6180 (casify_object): Avoid integer overflow when overallocating buffer.
6181 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
6182 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
6183 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
6184 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6185 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6186 integers are now checked earlier. All uses replaced with XINT.
6188 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6189 For CCL_MapSingle, check that content and value are in int range.
6190 (ccl_driver, Fregister_code_conversion_map):
6191 Check that Vcode_version_map_vector is a vector.
6192 (resolve_symbol_ccl_program): Check that vector header is in range.
6193 Always copy the vector, so that we can check its contents reliably
6194 now rather than having to recheck each instruction as it's being
6195 executed. Check that vector words fit in 'int'.
6196 (ccl_get_compiled_code, Fregister_ccl_program)
6197 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6198 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
6199 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
6200 contents are in range.
6201 (Fccl_execute_on_string): Check that status is in range.
6202 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
6203 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
6204 Accept and return EMACS_INT, not int, because callers can pass values
6206 (c_string_width, strwidth, lisp_string_width, chars_in_text)

6209 (str_as_unibyte, str_to_unibyte, string_count_byte8)
6210 (string_escape_byte8, Fget_byte):
6211 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6212 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
6213 avoid mishandling large integers.
6214 * character.h: Adjust decls to match defn changes elsewhere.
6215 * charset.c (load_charset_map_from_file, find_charsets_in_text)

6220 Don't assume fixnum fits in int.
6221 (load_charset_map_from_vector, Fmap_charset_chars):

6223 (Fdefine_charset_internal): Check ranges here, more carefully.
6224 Don't rely on undefined behavior with signed left shift overflow.
6225 Don't assume unsigned int fits into fixnum, or that fixnum fits
6226 into unsigned int. Don't require max_code to be a valid fixnum;
6227 that's not true for gb10830 4-byte on a 32-bit host. Allow
6228 invalid_code to be a cons, for the same reason. Require code_offset
6229 to be a character. Avoid int overflow if max_char is close
6231 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
6232 this is intended anyway and avoids some undefined behavior.
6233 (load_charset_map): Pass unsigned, not int, as 2nd arg of
6234 INDEX_TO_CODE_POINT, as that's what it expects.
6235 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
6236 * charset.h (DECODE_CHAR): Return int, not unsigned;
6237 this is what was intended anyway, and it avoids undefined behavior.
6238 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
6239 integer-overflow issues.
6240 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
6241 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
6242 where the argument is EMACS_INT, and this behavior is not intended.
6243 * chartab.c (Fmake_char_table, Fset_char_table_range)
6244 (uniprop_get_decoder, uniprop_get_encoder):
6245 Don't assume fixnum fits in int.
6246 * cmds.c (move_point): New function, that does the gist of
6247 Fforward_char and Fbackward_char, but does so while checking
6248 for integer overflow more accurately.
6249 (Fforward_char, Fbackward_char): Use it.
6250 (Fforward_line, Fend_of_line, internal_self_insert)
6251 (internal_self_insert):
6252 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6253 Fix a FIXME, by checking for integer overflow when calculating
6254 target_clm and actual_clm.

6286 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6287 (consume_chars): Rewrite to not calculate an address outside buffer.
6288 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
6289 Don't access memory outside of the args array.
6290 (Fdefine_coding_system_internal): Check for charset-id overflow.
6291 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
6292 result of ENCODE_CHAR.
6293 * coding.h: Adjust decls to match defn changes elsewhere.
6294 (struct coding_system):
6295 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

6310 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6311 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
6312 Do not attempt to compute the address of the object just before a
6313 buffer; this is not portable.
6315 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6316 (Faset): Use int, not EMACS_INT, where int is wide enough.
6317 (Fstring_to_number): Don't assume fixnums fit in int.

7056 testing that it->string is a Lisp string.
7057 (get_next_display_element): When the current object is exhausted,
7058 and there's something on it->stack, call set_iterator_to_next to
7059 proceed with what's on the stack, instead of returning zero.
7060 (set_iterator_to_next): If called at the end of a Lisp string,
7061 proceed to consider_string_end without incrementing string
7062 position. Don't increment display vector index past the end of
7063 the display vector. (Bug#11417)
7064 (pos_visible_p): Don't report a position visible when move_it_to
7065 stopped at the last line of window, which happens to be scanned
7066 backwards by the bidi iteration. (Bug#11464)
7068 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7070 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7071 and right-margin display specs even if the spec is invalid or we
7072 are on a TTY, and thus unable to display on the fringes.
7073 That's because the text with the property will not be displayed anyway,
7074 so we need to signal to the caller that this is a "replacing"
7075 display spec. This fixes display when the spec is invalid or we
7078 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7080 * unexaix.c (make_hdr): Fix typo in prototype.
7081 This bug broke the build on AIX. Problem reported by Gilles Pion.
7083 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
7085 * keyboard.c (kbd_buffer_get_event): Read special events also in
7086 batch mode. (Bug#11415)
7088 2012-05-12 Glenn Morris <rgm@gnu.org>
7090 * ns.mk: Update for ns_appbindir no longer having trailing "/".
7092 2012-05-12 Eli Zaretskii <eliz@gnu.org>
7094 * lisp.mk (lisp): Add newcomment.elc.
7096 2012-05-12 Glenn Morris <rgm@gnu.org>
7098 * Makefile.in (MKDIR_P): New, set by configure.
7099 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
7101 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
7103 Remove unused function hourglass_started.
7104 * dispextern.h (hourglass_started):
7105 * w32fns.c (hourglass_started):
7106 * xdisp.c (hourglass_started): Remove.
7108 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7110 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7111 Update dependencies.
7113 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7115 * xgselect.c (xg_select): Put maxfds+1 into a var.
7116 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
7118 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7120 2012-05-10 Dave Abrahams <dave@boostpro.com>
7122 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7123 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7125 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7127 * dbusbind.c (xd_registered_buses): New internal Lisp object.
7128 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7129 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7130 Initialize xd_registered_buses.
7132 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7134 Untag more efficiently if USE_LSB_TAG.
7135 This is based on a proposal by YAMAMOTO Mitsuharu in
7136 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7137 For an admittedly artificial (nth 8000 longlist) benchmark on
7138 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7139 Emacs's overall text size by 1%.
7140 * lisp.h (XUNTAG): New macro.
7141 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7142 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7143 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7144 * eval.c (Fautoload):
7145 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7146 * frame.h (XFRAME): Use XUNTAG.
7148 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7149 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7150 Remove unportable assumptions about print widths of types like
7152 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7153 intptr_t when converting between pointer and integer, to avoid GCC
7154 warnings about wrong width.
7156 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7158 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7159 stack for each reader_thread, instead of defaulting to 8MB
7160 determined by the linker. This avoids failures in creating
7161 subprocesses on Windows 7, see the discussion in this thread:
7162 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7164 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7166 Fix up display of the *Minibuf-0* buffer in the mini window.
7167 * keyboard.c (read_char): Don't clear the echo area if there's no
7169 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7170 contents of *Minibuf-0*) if there's no message displayed in its stead.
7172 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7174 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7177 2012-05-06 Chong Yidong <cyd@gnu.org>
7179 * lisp.mk (lisp): Update.
7181 2012-05-05 Jim Meyering <meyering@redhat.com>
7183 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7185 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7187 * data.c (PUT_ERROR): New macro.
7188 (syms_of_data): Use it. Add new error type `user-error'.
7189 * undo.c (user_error): New function.
7190 (Fprimitive_undo): Use it.
7191 * print.c (print_error_message): Adjust print style for `user-error'.
7192 * keyboard.c (user_error): New function.
7193 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7195 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7197 Do not limit current-time-string to years 1000..9999.
7198 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7199 (Fcurrent_time_string): Support any year that is supported by the
7200 underlying localtime representation. Don't use asctime, as it
7201 has undefined behavior for years outside the range -999..9999.
7203 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7205 Fix race conditions involving setenv, gmtime, localtime, asctime.
7206 Without this fix, interrupts could mess up code that uses these
7207 nonreentrant functions, since setting TZ invalidates existing
7208 tm_zone or tzname values, and since most of these functions return
7209 pointers to static storage.
7210 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7211 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7212 Grow the critical sections to include not just invoking
7213 localtime/gmtime, but also accessing these functions' results
7214 including their tm_zone values if any, and any related TZ setting.
7215 (format_time_string): Last arg is now struct tm *, not struct tm **,
7216 so that the struct tm is saved in the critical section.
7217 All callers changed. Simplify allocation of initial buffer, partly
7218 motivated by the fact that memory allocation needs to be outside
7219 the critical section.
7221 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7223 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7224 with RESET_INTERVAL.
7226 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7227 Remove duplicated buffer name initialization.
7229 2012-05-02 Jim Meyering <jim@meyering.net>
7231 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7233 * xfns.c (x_window): Use xstrdup (Bug#11375).
7235 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7237 * xdisp.c (pos_visible_p): If already at a newline from the
7238 display string before the 'while' loop, don't walk back the glyphs
7239 from it3.glyph_row. Solves assertion violation when the display
7240 string begins with a newline (egg.el). (Bug#11367)
7242 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7244 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7247 2012-05-01 Glenn Morris <rgm@gnu.org>
7249 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7250 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7251 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7252 All were removed before 23.1.
7254 * dispnew.c: Remove HAVE_LIBNCURSES test;
7255 it is always true on relevant platforms.
7257 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7258 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7260 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
7262 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
7264 * .gdbinit (xpr): Remove checks for no longer existing misc types.
7265 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
7268 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
7270 Do not avoid creating empty evaporating overlays (Bug#9642).
7271 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7272 That is, do not delete an evaporating overlay if it becomes
7273 empty after its bounds are adjusted to fit within its buffer.
7274 This fix caused other problems, and I'm reverting it until we get
7275 to the bottom of them.
7277 2012-04-27 Chong Yidong <cyd@gnu.org>
7279 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7281 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7283 * xdisp.c (pos_visible_p): If the window start position is beyond
7284 ZV, start the display from buffer beginning. Prevents assertion
7285 violation in init_iterator when the minibuffer window is scrolled
7288 * window.c (window_scroll_pixel_based): Likewise.
7290 2012-04-27 Chong Yidong <cyd@gnu.org>
7292 * keymap.c (where_is_internal): Doc fix (Bug#10872).
7294 2012-04-27 Glenn Morris <rgm@gnu.org>
7296 * fileio.c (Fcopy_file, Fset_file_selinux_context):
7297 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
7299 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7301 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
7302 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
7304 2012-04-26 Eli Zaretskii <eliz@gnu.org>
7306 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7307 display element, check also the underlying string or buffer
7308 character. (Bug#11341)
7310 * w32menu.c: Include w32heap.h.
7311 (add_menu_item): If the call to AppendMenuW (via
7312 unicode_append_menu) fails, disable Unicode menus only if we are
7313 running on Windows 9X/Me.
7315 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7317 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
7318 (xgetint): Add missing shift for LSB tags.
7320 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7322 * keyboard.c (read_char): Don't wipe echo area for select window
7323 events: These might get delayed via `mouse-autoselect-window'
7326 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
7328 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
7329 manipulation of :loaded-from data.
7331 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
7333 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
7334 now a cons (bug#11311).
7336 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7338 Do not create empty overlays with the evaporate property (Bug#9642).
7339 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7340 if it becomes empty after its bounds are adjusted to fit within
7341 its buffer. Without this fix, in a nonempty buffer (let ((o
7342 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7343 yields an empty overlay that has the evaporate property, which is
7344 not supposed to happen.
7346 Fix minor GTK3 problems found by static checking.
7347 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7348 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7349 (struct _EmacsFixedClass, emacs_fixed_get_type):

7357 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
7358 (EMACS_FIXED_GET_CLASS): Remove; unused.
7359 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
7361 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
7362 Problem reported by Juanma Barranquero for Windows -Wunused-function.
7364 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7366 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
7367 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
7368 (__malloc_size_t, __malloc_ptrdiff_t):
7369 Remove. All uses removed, replaced by the definiens if needed,
7370 since we can assume C89 or better now.
7371 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
7372 (protect_malloc_state, align, get_contiguous_space)
7373 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

7379 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
7380 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
7381 Define using prototypes, not old style.
7382 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
7383 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
7384 (align): Don't assume that signed integer overflow wraps around.
7385 Omit unused local var.
7386 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
7387 (_free_internal_nolock, memalign, mallochook, reallochook):
7388 Omit no-longer-needed casts.

7391 (struct hdr): The 'magic' member is now size_t, not unsigned long.
7393 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
7395 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

7440 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7442 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
7443 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
7444 Do not assume ptrdiff_t is the same width as 'int'.
7446 * alloc.c: Handle unusual debugging option combinations.
7447 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
7448 since the two debugging options are incompatible.
7449 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7451 (mem_init, mem_insert, mem_insert_fixup):
7452 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

7459 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7461 * sysdep.c [__FreeBSD__]: Minor cleanups.
7462 (list_system_processes, system_process_attributes) [__FreeBSD__]:
7463 Use Emacs indenting style more consistently. Avoid some casts.
7464 Use 'double' consistently rather than mixing 'float' and 'double'.
7466 2012-04-21 Eduard Wiebe <usenet@pusto.de>
7468 * sysdep.c (list_system_processes, system_process_attributes):
7469 Add implementation for FreeBSD (Bug#5243).

7482 * print.c (print_preprocess): Only check print_depth if print-circle
7484 (print_object): Check for cycles even when print-circle is nil and

7500 * xdisp.c (string_buffer_position_lim): Limit starting position to
7502 (set_cursor_from_row): If called for a mode-line or header-line
7503 row, return zero immediately.
7504 (try_cursor_movement): If inside continuation line, don't back up
7505 farther than the first row after the header line, if any.
7506 Don't consider the header-line row as "partially visible", even if
7507 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
7509 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

7523 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
7524 -Wunused-result, -Wunused-variable. This should go away once
7525 the Emacs and Gnulib regex code is merged.

7541 2012-04-16 Paul Eggert <eggert@cs.ucla.edu>
7543 Fix minor alloc.c problems found by static checking.
7544 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
7545 New extern decls, to avoid calling undeclared functions.
7546 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
7547 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
7548 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
7549 (NEED_MEM_INSERT): New macro.
7550 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
7551 Remove one incorrect comment and fix another.

7557 (r_alloc_sbrk): Now static.
7559 Improve ralloc.c interface checking.
7560 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

7564 [REL_ALLOC]: ... to here, to check interface.
7565 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
7566 Remove decls. This fixes an "It stinks!".
7568 * alloc.c (which_symbols): Fix alignment issue / type clash.
7570 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
7572 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
7573 (struct Lisp_Misc_Any): Likewise.
7574 (struct Lisp_Free): Likewise.

7583 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
7585 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
7586 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
7587 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
7588 * s/netbsd.h, s/sol2-6.h:
7589 Remove definition of GC_MARK_STACK, since the default now works.
7590 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
7591 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
7592 no longer the default.
7593 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
7595 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
7597 * lread.c (lisp_file_lexically_bound_p):

7605 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
7607 * nsterm.m (constrainFrameRect): Always constrain when there is only
7608 one screen (Bug#10962).
7610 2012-04-13 Ken Brown <kbrown@cornell.edu>
7612 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.

7618 2012-04-11 Daniel Colascione <dancol@dancol.org>
7620 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
7621 against is gone. It's better to use vfork now so that when Cygwin
7622 gains a new, working vfork, we use it automatically (bug#10398).
7624 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
7626 * window.c (save_window_save): Obey window-point-insertion-type.

7640 (handle_interrupt): Use it.
7642 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
7644 * w32.c (w32_delayed_load): Record the full path of the library
7645 being loaded (bug#10424).
7647 2012-04-09 Glenn Morris <rgm@gnu.org>
7649 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
7650 not just in the obarray, before snarfing them. (Bug#11036)
7652 * Makefile.in ($(leimdir)/leim-list.el):
7653 Pass EMACS rather than BUILT_EMACS.

7662 Add convenience `GNUTLS_LOG2i' macro.
7664 * gnutls.c (gnutls_log_function2i): Convenience log function.
7665 (emacs_gnutls_read): Use new log functions,
7666 `gnutls_handshakes_tried' process member, and

7677 * minibuf.c (Fread_variable): Callers changed.
7679 2012-04-09 Eli Zaretskii <eliz@gnu.org>
7681 * xdisp.c (set_cursor_from_row): If the display string appears in
7682 the buffer at position that is closer to point than the position
7683 after the display string, display the cursor on the first glyph of
7684 the display string. Fixes cursor display when a 'display' text
7685 property immediately follows invisible text. (Bug#11094)
7687 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
7689 composite.c: use 'double' consistently
7690 * composite.c (get_composition_id): Use 'double' consistently
7691 instead of converting 'float' to 'double' and vice versa; this is
7692 easier to understand and avoids a GCC warning.
7694 2012-04-09 Glenn Morris <rgm@gnu.org>
7696 * Makefile.in: Generate leim-list with bootstrap-emacs, in
7697 preparation for dumping it with emacs. (Bug#4789)

7716 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
7718 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
7719 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
7720 (mark_memory): Mark Lisp_Objects only if pointers might hide in
7721 objects, as mark_maybe_pointer will catch them otherwise.
7722 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
7723 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
7725 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
7727 Fix typo that broke non-Windows builds.
7728 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
7730 2012-04-07 Eli Zaretskii <eliz@gnu.org>
7732 Support building on MS-Windows with libxml2.
7734 * makefile.w32-in (OBJ2): Add xml.$(O).
7735 (GLOBAL_SOURCES): Add xml.c.
7736 ($(BLD)/xml.$(O)): New dependency list.
7738 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
7739 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
7740 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
7741 [!WINDOWSNT]: New macros.
7742 (init_libxml2_functions, libxml2_loaded_p): New functions.
7743 (parse_region): Call fn_xmlCheckVersion instead of using the macro
7744 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
7745 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
7746 Calls xmlCleanupParser only if libxml2 was loaded (or statically
7748 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
7749 Call init_libxml2_functions before calling libxml2 functions.
7750 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
7752 * emacs.c: Don't include libxml/parser.h.
7753 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
7754 xmlCleanupParser directly.
7756 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
7758 2012-04-07 Eli Zaretskii <eliz@gnu.org>
7760 * indent.c (Fvertical_motion): If there is a display string at
7761 point, use it.vpos to compute how many lines to backtrack after
7762 move_it_to point. (Bug#11133)

7766 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
7767 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
7768 about subtle differences between FETCH_CHAR* and STRING_CHAR*
7769 macros related to unification of CJK characters. For the details,
7770 see the discussion following the message here:
7771 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
7773 2012-04-04 Chong Yidong <cyd@gnu.org>
7775 * keyboard.c (Vdelayed_warnings_list): Doc fix.
7777 2012-04-01 Eli Zaretskii <eliz@gnu.org>
7779 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

7787 2012-03-31 Eli Zaretskii <eliz@gnu.org>
7789 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
7790 position we get to after a call to move_it_to fails the
7791 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
7792 only if we wind up in a string from display property. (Bug#11063)
7794 * window.c (Fdelete_other_windows_internal): Invalidate the row
7795 and column information about mouse highlight, so that redisplay
7796 restores it after reallocating the glyph matrices. (Bug#7464)
7798 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
7799 string comes from a `display' text property, use the buffer
7800 position of that property as if we actually saw that position in
7802 (move_it_by_lines): Remove the assertion that
7803 "it->current_x == 0 && it->hpos == 0" which can be legitimately
7804 violated when there's a before-string at the beginning of a line.
7807 2012-03-30 Eli Zaretskii <eliz@gnu.org>
7809 * xdisp.c (append_space_for_newline): If the default face was
7810 remapped, use the remapped face for the appended newline.
7811 (extend_face_to_end_of_line): Use the remapped default face for
7812 extending the face to the end of the line.
7813 (display_line): Call extend_face_to_end_of_line when the default
7814 face was remapped. (Bug#11068)
7816 2012-03-29 Eli Zaretskii <eliz@gnu.org>
7818 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

7838 handle-select-window too (Bug#8996).
7840 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
7842 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
7844 2012-03-25 Kenichi Handa <handa@m17n.org>
7846 * dispextern.h (struct glyph): Change the bit length of
7847 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
7849 2012-03-24 Eli Zaretskii <eliz@gnu.org>
7851 * s/ms-w32.h (tzname): Include time.h before redirecting to
7852 _tzname. Fixes the MSVC build. (Bug#9960)
7854 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
7856 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
7859 * xterm.c (XTread_socket): Only modify handling_signal if
7860 !SYNC_INPUT. (Bug#11080)
7862 2012-03-23 Eli Zaretskii <eliz@gnu.org>
7864 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
7865 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
7866 when fetching a multibyte character consumes more bytes than
7867 CHAR_BYTES returns, due to unification of CJK characters in
7868 string_char. (Bug#11073)
7870 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
7872 * process.c (wait_reading_process_output): Handle pty disconnect

7884 2012-03-21 Chong Yidong <cyd@gnu.org>
7886 * xfaces.c (Vface_remapping_alist): Doc fix.
7888 2012-03-20 Eli Zaretskii <eliz@gnu.org>
7890 * w32proc.c (Fw32_set_console_codepage)
7891 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

7902 it fit in a valid range (Bug#11003).
7904 2012-03-18 Eli Zaretskii <eliz@gnu.org>
7906 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
7907 that is not from display property, accept the row as a "cursor
7908 row" if one of the string's character has a non-nil `cursor'
7909 property. Fixes cursor positioning when there are newlines in
7910 overlay strings, e.g. in icomplete.el. (Bug#11035)
7912 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
7914 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
7916 2012-03-12 Chong Yidong <cyd@gnu.org>
7918 * eval.c (inhibit_lisp_code): Rename from
7919 inhibit_window_configuration_change_hook; move from window.c.
7921 * xfns.c (unwind_create_frame_1, Fx_create_frame):
7922 * window.c (run_window_configuration_change_hook)
7923 (syms_of_window): Callers changed.
7925 2012-03-11 Chong Yidong <cyd@gnu.org>
7927 * keymap.c (Fkey_description): Doc fix (Bug#9700).
7929 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
7931 2012-03-10 Chong Yidong <cyd@gnu.org>
7933 * frame.c (other_visible_frames): Don't assume the selected frame
7934 is visible (Bug#10955).
7936 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
7938 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
7940 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
7942 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
7943 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
7946 2012-03-03 Glenn Morris <rgm@gnu.org>
7948 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
7950 2012-03-02 Eli Zaretskii <eliz@gnu.org>
7952 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
7953 position past the first glyph_row that ends at ZV. (Bug#10902)
7954 (redisplay_window, next_element_from_string): Fix typos in
7956 (redisplay_window): Pass to move_it_vertically the margin in
7957 pixels, not in screen lines.
7959 2012-03-02 Glenn Morris <rgm@gnu.org>
7961 * buffer.c (buffer-list-update-hook): Doc fix.
7963 2012-02-29 Eli Zaretskii <eliz@gnu.org>
7965 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
7966 push_it before setting up the iterator for the first overlay
7967 string, even if we have an empty string loaded.
7968 (next_overlay_string): If there's an empty string on the iterator
7969 stack, pop the stack. (Bug#10903)
7971 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
7973 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
7974 Suggested by Stefan Monnier in
7975 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
7976 * alloc.c (widen_to_Lisp_Object): New static function.
7977 (mark_memory): Also mark Lisp_Objects by fetching pointer words
7978 and widening them to Lisp_Objects. This would work even if
7979 USE_LSB_TAG is defined and wide integers are used, which might
7980 happen in a future version of Emacs.
7982 2012-02-25 Chong Yidong <cyd@gnu.org>
7984 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

8021 when computing $valmask.
8023 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8024 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8025 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8026 It's useless in that case, and it can cause problems on hosts
8027 that allocate halves of EMACS_INT values separately.
8028 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8029 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8030 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8031 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8032 it avoids undefined behavior on hosts where shifting right by more
8033 than the word width has undefined behavior.
8035 2012-02-19 Chong Yidong <cyd@gnu.org>
8037 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)

8081 highlight (Bug#9904).
8083 2012-02-12 Glenn Morris <rgm@gnu.org>

8115 * buffer.c (Fbuffer_local_variables)
8116 (buffer_lisp_local_variables): Handle unbound vars correctly;

8159 * character.c (char_width): Return EMACS_INT, not int.
8160 (char_width, c_string_width): Check for overflow when
8161 computing the width; this is possible now that individual
8162 characters can have unbounded width. Problem introduced

8835 behave as if the cursor position were at the window margin.
8837 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
8838 and the cursor position is out of bounds, behave as if the cursor

8869 * dispnew.c (verify_row_hash): Call row_hash for computing the
8870 hash code of a row, instead of duplicating code from xdisp.c.
8872 * dispextern.h (row_hash): Add prototype.
8874 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
8876 * frame.c (delete_frame): Don't delete the terminal when the last

8981 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
8983 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
8984 (window_box_width, window_box_left, window_box_left_offset)
8985 (window_box_right, window_box_right_offset): Undo previous change,
8986 by removing the "extern"s.
8987 * intervals.c (adjust_intervals_for_insertion)
8988 (adjust_intervals_for_deletion): Undo previous change,
8989 making these static again.
8990 (offset_intervals, temp_set_point_both, temp_set_point)
8991 (copy_intervals_to_string): No longer inline.
8992 * xdisp.c (window_text_bottom_y, window_box_width)
8993 (window_box_height, window_box_left_offset)
8994 (window_box_right_offset, window_box_left, window_box_right)
8995 (window_box): No longer inline.

9003 (Fwindow_total_size, Fwindow_body_size): Move to Lisp.
9005 2011-11-07 Juanma Barranquero <lekktu@gmail.com>
9007 * lisp.h (syms_of_abbrev): Remove declaration.
9008 Reported by CHENG Gao <chenggao@royau.me>.
9010 2011-11-07 Eli Zaretskii <eliz@gnu.org>
9012 * w32.c (check_windows_init_file): Don't look for term/w32-win.el
9013 if Vpurify_flag is non-nil. Fixes a crash when running w32 build
9014 of temacs in GUI mode.
9016 2011-11-07 Martin Rudalics <rudalics@gmx.at>
9018 * window.h: Declare delete_all_child_windows instead of
9019 delete_all_subwindows.
9020 * window.c (Fwindow_nest, Fset_window_nest)
9021 (Fset_window_new_total, Fset_window_new_normal)

9023 (delete_all_subwindows): Rename to delete_all_child_windows.
9024 (Fdelete_other_windows_internal, Fset_window_configuration):
9025 Call delete_all_child_windows instead of delete_all_subwindows.
9026 * frame.c (delete_frame): Call delete_all_child_windows instead
9027 of delete_all_subwindows.
9029 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
9031 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
9032 This is also needed for porting to any host where GC_MARK_STACK is
9033 not GC_MAKE_GCPROS_NOOPS.
9034 (which_symbols): Use it.
9036 2011-11-07 Kenichi Handa <handa@m17n.org>
9038 * coding.c (coding_set_destination): Check coding->src_pos only

9042 to 0 (bug#9911) when sending a unibyte text.
9044 * callproc.c (Fcall_process): Set the member src_multibyte of
9045 process_coding to 0 (bug#9912).
9047 2011-11-06 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9049 * xmenu.c (cleanup_widget_value_tree): New function.
9050 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
9051 calling free_menubar_widget_value_tree directly (Bug#9830).
9053 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
9055 Fix some portability problems with 'inline'.
9056 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
9057 (window_box_width, window_box_left, window_box_left_offset)
9058 (window_box_right, window_box_right_offset): Declare extern.
9059 Otherwise, these inline functions do not conform to C99 and
9060 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
9061 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
9062 * intervals.c (adjust_intervals_for_insertion)
9063 (adjust_intervals_for_deletion): Now extern, because otherwise the
9064 extern inline functions 'offset_intervals' couldn't refer to it.
9065 (static_offset_intervals): Remove.
9066 (offset_intervals): Rewrite using the old contents of
9067 static_offset_intervals. The old version didn't conform to C99
9068 because an extern inline function contained a reference to an
9069 identifier with static linkage.
9071 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
9073 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

9089 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
9090 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
9091 (Fwindow_vscroll): Doc fix.
9092 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
9093 argument, since it makes no sense to pass a live window and for
9094 consistency with window-child.

9122 (unwind_create_frame): New function (Bug#9943).
9123 (Fx_create_frame): Restructure code to be more similar to the one in
9124 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
9125 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
9126 Move terminal->reference_count++ just before making the frame official

9181 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
9182 label is not null (Bug#9951).

9205 Rename cover_string to disp_string.
9207 2011-11-01 Martin Rudalics <rudalics@gmx.at>

9238 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
9240 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
9241 so that this new function doesn't get optimized away by a
9242 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
9244 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
9246 * frame.h (MOUSE_HL_INFO): Remove excess parens.
9248 2011-10-29 Eli Zaretskii <eliz@gnu.org>

9264 2011-10-29 Glenn Morris <rgm@gnu.org>
9266 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
9267 Not clear what it was for, and it causes various bugs. (Bug#9839)
9269 2011-10-28 Eli Zaretskii <eliz@gnu.org>
9271 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
9272 possible random value that matches one of those tested as
9273 condition to clear the mouse face.
9275 2011-10-28 Chong Yidong <cyd@gnu.org>
9277 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

9302 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
9304 (w32font_open_internal, compute_metrics):
9305 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
9306 instead of calling the "wide" APIs directly.
9308 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
9310 * w32.h (syms_of_w32font): Add prototype.
9312 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9314 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
9315 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
9316 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
9317 (Fmove_to_window_line): Doc fix.
9319 2011-10-27 Chong Yidong <cyd@gnu.org>
9321 * process.c (make_process): Set gnutls_state to NULL.
9323 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
9324 non-NULL, regardless of GNUTLS_INITSTAGE.
9325 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
9326 an error. Set process slots as soon as we allocate them.

9372 current character, check also for next_en_type being WEAK_EN.
9373 (bidi_resolve_weak): Don't enter the expensive loop if the current
9374 position is before next_en_pos. Record the bidi type of the first
9375 non-ET, non-BN character we find, in addition to its position.
9376 (bidi_level_of_next_char): Invalidate next_en_type when
9377 next_en_pos is over-stepped.
9379 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
9381 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
9382 * editfns.c: Rewrite current-time-zone so that it invokes
9383 the equivalent of (format-time-string "%Z") to get the time zone name.
9384 This fixes a bug when the time zone name contains characters that
9385 need converting from the system time locale to Emacs internal format.
9386 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9387 that patch fixed format-time-string to do the conversion, but
9388 I forgot to fix current-time-zone.
9389 (format_time_string): New function, containing most of
9390 what Fformat_time_string used to contain.
9391 (Fformat_time_string): Rewrite in terms of format_time_string.
9392 This doesn't change this function's behavior.
9393 (current-time-zone): Rewrite to use format_time_string.
9394 This fixes the bug reported by Michael Schierl in
9395 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9396 Jason Rumney's 2007-06-07 change worked around this bug, but
9398 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9400 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9402 * xdisp.c (start_display): If the character at POS is displayed
9403 via a display vector, reset IT->current.dpvec_index to zero.
9404 (try_window_reusing_current_matrix): If a line ends in a display
9405 vector or the next line starts in a display vector, continue
9406 redrawing the window even though the character position of
9407 start_row was reached.
9410 2011-10-18 Chong Yidong <cyd@gnu.org>
9412 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9413 with nobreak-char-display too.
9415 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9417 Fix part 3 of bug#9771.
9418 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9419 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9420 non-neutral characters if the current character is a paragraph
9421 separator (a.k.a. Newline). This avoids running the same
9422 expensive loop twice, once when we consume the preceding newline
9423 and the other time when the line actually needs to be displayed.
9424 Avoid the loop when we see neutrals on the base embedding level
9425 following a character whose directionality is the same as the
9426 paragraph's. This avoids running the expensive loop when a line
9427 ends in a long sequence of neutrals, like control characters.
9428 Add assertion against STRONG_AL type. Slightly rearrange code
9429 that determines the type of a neutral given the first non-neutral
9431 (bidi_level_of_next_char): Set next_en_pos to zero when
9432 invalidating its info.
9434 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9436 * xdisp.c (push_display_prop): Determine whether to record string
9437 or buffer position by IT->string, not by IT->method. Allow
9438 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9439 (move_it_vertically_backward): Don't look for character position
9440 immediately after the newline when in a continuation line.
9443 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9445 * window.c (coordinates_in_window): Rewrite and delabelize
9446 vertical border check. (Bug#5357) (Bug#9618)
9448 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9450 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9451 errors in XSetWindowBorder (bug#9310).
9453 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9455 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9456 avoid crash when xmalloc overrun checking is enabled.
9458 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9460 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9461 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9462 cursor motion with <left> and <right> arrow keys.
9464 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9465 some callers set that themselves.
9467 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9469 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9470 display string and the previous row comes from the same string and
9471 is empty. (Bug#9739) (Bug#9738)
9473 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9475 * doc.c (get_doc_string): Encode file name (bug#9735).
9477 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9479 * bidi.c (bidi_level_of_next_char):
9480 * xdisp.c (get_visually_first_element): Remove old incorrect
9481 comments regarding the Unicode Line Separator character.
9483 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9485 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9487 * alloc.c (Fgc_status): Do not access beyond zombies array
9488 boundary if nzombies > MAX_ZOMBIES.
9489 * alloc.c (dump_zombies): Add missing format specifier.
9491 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9493 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9494 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9496 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9497 Some packages use them to denote characters with modifiers.
9499 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9501 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9502 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9503 matching a pp-number. Rename parameter var to var1.
9505 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9507 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9509 2011-10-08 Glenn Morris <rgm@gnu.org>
9511 * callint.c (Fcall_interactively): Give a more explicit error for the
9512 'c' case with a non-character input. (Bug#8479)
9514 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9516 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9518 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9519 lines that are hscrolled on the left.
9521 * dispnew.c (buffer_posn_from_coords): Account for a possible
9522 presence of header-line. (Bug#4426)
9524 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
9526 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
9527 Don't advertise functionality which we discourage or doesn't work.
9529 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
9531 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
9532 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
9533 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
9534 this makes Emacs dump core during garbage collection on rare
9535 occasions. sizeof is obviously inferior to offsetof here, so
9536 stick with offsetof.
9537 (GC_POINTER_ALIGNMENT): New macro.
9538 (mark_memory): Omit 3rd (offset) arg; caller changed.
9539 Don't assume EMACS_INT alignment is the same as pointer alignment.
9541 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
9543 * keyboard.c (read_key_sequence_remapped): New var.
9544 (read_key_sequence): Compute remapping in the right buffer.
9545 (command_loop_1): Use read_key_sequence's remapping directly.
9547 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
9549 * dired.c (file_name_completion): Don't expand file name.
9550 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
9551 before checking file name handler.
9553 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
9554 they've been requested explicitly (bug#9591).
9556 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
9558 * keymap.c (Fsingle_key_description): Use make_specified_string
9559 instead of build_string to build string from push_key_description.
9562 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9564 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
9565 This fixes a Y2038 bug on 64-bit hosts.
9566 * buffer.c (reset_buffer):
9567 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
9568 (Fclear_buffer_auto_save_failure):
9569 Use 0, not -1, to represent an unset failure time, since time_t
9570 might not be signed.
9572 Remove dependency on glibc malloc internals.
9573 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9574 Move back here from lisp.h, but with their new implementations.
9575 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9576 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
9577 * charset.c (charset_table_init): New static var.
9578 (syms_of_charset): Use it instead of xmalloc. This removes a
9579 dependency on glibc malloc internals. See Eli Zaretskii's comment in
9580 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
9581 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9582 Move back to alloc.c.
9583 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9584 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
9586 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
9588 * nsterm.m (windowDidResize): Call x_set_window_size only when
9589 ns_in_resize is true. Otherwise set pixelwidth/height and
9590 call change_frame_size (Bug#9628).
9592 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9594 Port --enable-checking=all to Fedora 14 x86-64.
9595 * charset.c (syms_of_charset): Also account for glibc malloc's
9596 internal overhead when calculating the initial malloc maximum.
9598 Port --enable-checking=all to Fedora 14 x86.
9599 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9601 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
9602 (overrun_check_realloc, overrun_check_free):
9603 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
9604 That way, xmalloc returns a properly-aligned pointer even if
9605 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
9606 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
9607 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
9608 into account when calculating the initial malloc maximum.
9609 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9610 Move here from alloc.c, so that charset.c can use it too.
9611 Properly align; the old code wasn't right for common 32-bit hosts
9612 when configured with --enable-checking=all.
9613 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9614 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
9616 2011-09-29 Eli Zaretskii <eliz@gnu.org>
9618 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
9621 2011-09-28 Eli Zaretskii <eliz@gnu.org>
9623 * xdisp.c (compute_display_string_end): If there's no display
9624 string at CHARPOS, return -1.
9626 * bidi.c (bidi_fetch_char): When compute_display_string_end
9627 returns a negative value, treat the character as a normal
9628 character not covered by a display string. (Bug#9624)
9630 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
9632 * lread.c (Fread_from_string): Fix typo in docstring.
9634 2011-09-27 Eli Zaretskii <eliz@gnu.org>
9636 * xdisp.c (handle_invisible_prop): If invisible text ends on a
9637 newline, reseat the iterator instead of bidi-iterating there one
9638 character at a time. (Bug#9610)
9639 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
9640 TO_CHARPOS if the bidi iterator is at base embedding level.
9642 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
9644 * lread.c (readevalloop): Use correct code for NBSP.
9645 (read1): Likewise. (Bug#9608)
9647 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
9649 * dbusbind.c (Fdbus_register_signal): When service is not
9650 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
9652 2011-09-25 Glenn Morris <rgm@gnu.org>
9654 * buffer.c (truncate-lines): Doc fix.
9656 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
9658 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
9659 (Fset_window_next_buffers): Doc fix.
9661 2011-09-24 Glenn Morris <rgm@gnu.org>
9663 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
9665 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
9667 Fix minor problems found by static checking.
9668 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
9669 * indent.c (Fvertical_motion): Fix == vs = typo.
9671 2011-09-24 Eli Zaretskii <eliz@gnu.org>
9673 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
9674 Default value is now t. Doc fix.
9676 * indent.c (Fvertical_motion): Compute and apply the overshoot
9677 logic when moving up, not only when moving down. Fix the
9678 confusing name and values of the it_overshoot_expected variable;
9679 logic changes accordingly. (Bug#9254) (Bug#9549)
9681 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
9682 CHARPOS is covered by a display string which includes newlines.
9683 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
9684 is covered by a display string with embedded newlines.
9686 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
9688 * dbusbind.c (Fdbus_register_signal): Add match rule to
9689 Vdbus_registered_objects_table. (Bug#9581)
9690 (Fdbus_register_method, Vdbus_registered_objects_table):
9693 2011-09-24 Jim Meyering <meyering@redhat.com>
9695 do not ignore write error for any output size
9696 The previous change was incomplete.
9697 While it makes emacs --batch detect the vast majority of stdout
9698 write failures, errors were still ignored whenever the output size is
9699 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
9700 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
9701 && echo FAIL: ignored write error
9702 FAIL: ignored write error
9703 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
9704 && echo FAIL: ignored write error
9705 FAIL: ignored write error
9706 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
9708 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>

9711 non-successfully if a write error occurred on stdout. (Bug#9574)
9713 2011-09-21 Eli Zaretskii <eliz@gnu.org>
9715 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
9718 * dispextern.h (struct it): Update the comment documenting what
9721 2011-09-20 Eli Zaretskii <eliz@gnu.org>
9723 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
9724 a display string, extend search for cursor position to end of row.
9725 (find_row_edges): If the row ends in a newline from a display
9726 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
9727 Handle the case of a display string with multiple newlines.
9728 (Fcurrent_bidi_paragraph_direction): Fix search for previous
9729 non-empty line. Fixes confusing cursor motion with arrow keys at
9730 the beginning of a line that starts with whitespace.

9739 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
9742 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9744 * xdisp.c (display_line): Record maximum and minimum buffer
9745 positions even if no glyphs were produced (e.g., by a zero-width
9746 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
9747 buffer positions that will be removed from the glyph row because
9749 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
9750 column is beyond frame width: don't subtract 1 "pixel" when
9751 computing width of the stretch.
9752 (reseat_at_next_visible_line_start): Undo the change made on
9753 2011-09-17 that saved paragraph information and restored it after
9754 the call to `reseat'. (Bug#9545)
9756 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9758 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
9759 and turn window cursor on if cleared (Bug#9415).
9761 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
9763 * search.c (boyer_moore): Take unibyte characters from pattern

9772 Fix minor problem found by static checking.
9773 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
9774 initialized, to pacify gcc -Wuninitialized.
9776 * fileio.c: Report proper errno when syscall falls.
9777 (Finsert_file_contents): Save and restore errno,
9778 so that report_file_error outputs the correct diagnostic.
9779 (Fwrite_region) [CLASH_DETECTION]: Likewise.
9781 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9783 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
9785 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9787 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
9788 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
9790 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9792 * xdisp.c (reseat_at_next_visible_line_start): Keep information
9793 about the current paragraph and restore it after the call to reseat.
9795 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
9796 (bidi_find_paragraph_start): Search back for paragraph beginning
9797 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
9798 (bidi_move_to_visually_next): Only trigger paragraph-related
9799 computations when the last character is a newline or at EOB, not
9800 just any NEUTRAL_B. (Bug#9470)

9807 * xselect.c: Relax test for outgoing X longs (Bug#9498).
9808 (cons_to_x_long): New function.
9809 (lisp_data_to_selection_data): Use it. Correct the test for
9810 short-versus-long data; it was negated. Break out of vector
9811 loop, for efficiency, when a long datum is discovered.
9813 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
9815 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
9817 2011-09-16 Eli Zaretskii <eliz@gnu.org>
9819 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
9820 GCC PR/17406) by declaring this function with external scope.
9822 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>

9843 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
9844 This occurs when processing a multibyte format.
9845 Problem reported by Wolfgang Jenker.
9847 2011-09-15 Johan Bockgård <bojohan@gnu.org>
9849 * xdisp.c (try_cursor_movement): Only check for exact match if
9850 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
9852 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9854 Remove unused external symbols.
9855 * dispextern.h (calc_pixel_width_or_height): Remove decl.

9857 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
9858 * indent.c (check_display_width):
9859 * w32term.c: Fix comment to match code.
9860 * xterm.c, xterm.h (x_catching_errors): Remove.
9862 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9864 * xselect.c: Use signed conversions more consistently (Bug#9498).
9865 (selection_data_to_lisp_data): Assume incoming selection data are
9866 signed integers, not unsigned. This is to be consistent with
9867 outgoing selection data, which was modified to use signed integers
9868 in as part of the fix to Bug#9196 in response to Jan D.'s comment
9869 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
9870 expects long, not unsigned long.

9874 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
9875 computation of loop end. Reported by Johan Bockgård

9885 rather than the other way around. (Bug#2496)
9887 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>

9900 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
9902 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
9903 value for non-existent files.
9905 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9907 * fileio.c (Finsert_file_contents): If the file cannot be opened,
9908 set its "size" to -1. This will set the modtime_size field of
9909 the corresponding buffer to -1, which is what
9910 verify-visited-file-modtime expects for files that do not exist.
9913 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
9915 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
9917 * lisp.h: ... from here. push_key_description is no longer
9918 defined in keyboard.c, so its declaration should not be in
9919 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
9920 logically belongs with push_key_description.
9922 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
9924 * buffer.h: Include <sys/types.h> instead of <time.h>.
9925 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
9926 Problem reported by Herbert J. Skuhra.
9928 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
9930 * xml.c (parse_region): Make the parsing work for
9931 non-comment-starting XML files again (bug#9144).
9933 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
9935 * image.c (gif_load): Fix calculation of bottom and right corner.
9938 2011-09-10 Eli Zaretskii <eliz@gnu.org>
9940 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
9941 redisplay in small windows.
9943 2011-09-09 Eli Zaretskii <eliz@gnu.org>
9945 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
9947 2011-09-08 Martin Rudalics <rudalics@gmx.at>
9949 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
9950 Operate on live windows only.
9952 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
9954 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
9956 2011-09-07 Eli Zaretskii <eliz@gnu.org>
9958 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
9959 only under bidi iteration.
9961 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
9963 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
9965 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9967 isnan: Fix porting problem to Solaris 10 with bundled gcc.
9968 Without this fix, the command to link temacs failed due to an
9969 undefined symbol __builtin_isnan. This is because
9970 /usr/include/iso/math_c99.h #defines isnan(x) to
9971 __builtin_isnan(x), but the bundled gcc, which identifies itself
9972 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
9974 * floatfns.c (isnan): #undef, and then #define to a clone of
9976 (Fisnan): Always define, since it's always available now.
9977 (syms_of_floatfns): Always define isnan at the Lisp level.
9979 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9981 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
9983 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9985 * fileio.c: Fix bugs with large file offsets (Bug#9428).
9986 The previous code assumed that file offsets (off_t values) fit in
9987 EMACS_INT variables, which is not true on typical 32-bit hosts.
9988 The code messed up by falsely reporting buffer overflow in cases
9989 such as (insert-file-contents "big" nil 1 2) into an empty buffer
9990 when "big" contains more than 2**29 bytes, even though this
9991 inserts just one byte and does not overflow the buffer.
9992 (Finsert_file_contents): Store file offsets as off_t
9993 values, not as EMACS_INT values. Check for overflow when
9994 converting between EMACS_INT and off_t. When checking for
9995 buffer overflow or for overlap, take the offsets into account.
9996 Don't use EMACS_INT for small values where int suffices.
9997 When checking for overlap, fix a typo: ZV was used where
9998 ZV_BYTE was intended.
9999 (Fwrite_region): Don't assume off_t fits into 'long'.
10000 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10002 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10004 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10006 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10008 sprintf-related integer and memory overflow issues (Bug#9412).
10010 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10011 (esprintf, exprintf, evxprintf): New functions.
10012 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10013 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10014 (modify_event_symbol): Do not assume that the length of
10015 name_alist_or_stem is safe to alloca and fits in int.
10016 (Fexecute_extended_command): Likewise for function name and binding.
10017 (Frecursion_depth): Wrap around reliably on integer overflow.
10018 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10019 since some callers pass EMACS_INT values.
10020 (Fsingle_key_description): Don't crash if symbol name contains more
10021 than MAX_ALLOCA bytes.
10022 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10023 (get_minibuffer): Arg is now EMACS_INT, not int.
10024 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10025 (esprintf, exprintf, evxprintf): New decls.
10026 * window.h (command_loop_level, minibuf_level): Reflect API changes.
10028 * dbusbind.c (signature_cat): New function.
10029 (xd_signature, Fdbus_register_signal):
10030 Do not overrun buffer; instead, report string overflow.
10032 * dispnew.c (add_window_display_history): Don't overrun buffer.
10033 Truncate instead; this is OK since it's just a log.
10035 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10036 even if the time zone offset is outlandishly large.
10037 Don't mishandle offset == INT_MIN.
10039 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10040 when creating daemon; the previous buffer-overflow check was incorrect.
10042 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10043 which has the guts of the old verror function.
10045 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10046 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10048 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10049 (font_unparse_xlfd): Don't blindly alloca long strings.
10050 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10051 fits in int, when using sprintf. Use single snprintf to count
10052 length of string rather than counting it via multiple sprintfs;
10053 that's simpler and more reliable.
10054 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10055 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10056 sprintf, in case result does not fit in int.
10058 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10059 (fontset_from_font): Print it.
10061 * frame.c (tty_frame_count): Now printmax_t, not int.
10062 (make_terminal_frame, set_term_frame_name): Print it.
10063 (x_report_frame_params): In X, window IDs are unsigned long,
10064 not signed long, so print them as unsigned.
10065 (validate_x_resource_name): Check for implausibly long names,
10066 and don't assume name length fits in 'int'.
10067 (x_get_resource_string): Don't blindly alloca invocation name;
10068 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10071 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10072 (xg_check_special_colors, xg_set_geometry):
10073 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10075 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10076 Use esprintf, not sprintf, in case result does not fit in int.
10078 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10079 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10080 it as a large positive number.
10081 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10082 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10084 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10085 in case result does not fit in int.
10087 * print.c (float_to_string): Detect width overflow more reliably.
10088 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10089 buffer overrun. Don't assume list length fits in 'int'. Treat
10090 print length of 0 as 0, not as infinity; to be consistent with other
10091 uses of print length in this function. Don't overflow print length
10092 index. Don't assume hash table size fits in 'long', or that
10093 vectorlike size fits in 'unsigned long'.
10095 * process.c (make_process): Use printmax_t, not int, to format
10096 process-name gensyms.
10098 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10100 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10101 to avoid potential buffer overrun.
10103 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10104 if X resource line is longer than 512 bytes.
10106 * xfns.c (x_window): Make sprintf buffer a bit bigger
10107 to avoid potential buffer overrun.
10109 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10111 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10113 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10115 Integer overflow fixes for scrolling, etc.
10116 Without these, Emacs silently mishandles large integers sometimes.
10117 For example, "C-u 4294967297 M-x recenter" was treated as if
10118 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10120 * xdisp.c (try_window_id): Check Emacs fixnum range before
10121 converting to 'int'.
10123 * window.c (window_scroll_line_based, Frecenter):
10124 Check that an Emacs fixnum is in range before assigning it to 'int'.
10125 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10126 values converted from Emacs fixnums.
10127 (Frecenter): Don't wrap around a line count if it is out of 'int'
10128 range; instead, treat it as an extreme value.
10129 (Fset_window_configuration, compare_window_configurations):
10130 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10132 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10133 that can exceed INT_MAX. Check that EMACS_INT value is in range
10134 before assigning it to the (possibly-narrower) index.
10135 (match_limit): Don't assume that a fixnum can fit in 'int'.
10137 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10140 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10141 (Fvertical_motion): Don't wrap around LINES values that don't fit
10142 in 'int'. Instead, treat them as extreme values. This is good
10143 enough for windows, which can't have more than INT_MAX lines anyway.
10145 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10147 * Require libxml/parser.h to avoid compilation warning.
10149 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10151 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10152 since this reportedly can destroy thread storage.
10154 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10156 * syntax.c (find_defun_start): Update all cache variables if
10157 exiting early (Bug#9401).
10159 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10161 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10163 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10164 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10165 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10167 * term.c (tty_append_glyph): New function.
10168 (produce_stretch_glyph): Static function and its prototype deleted.
10170 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10173 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10175 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10176 when checking :margin (Bug#9390).
10177 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10178 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10179 so that the name doesn't mislead. All uses changed.
10181 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10183 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
10186 2011-08-27 Eli Zaretskii <eliz@gnu.org>
10188 * xdisp.c (move_it_to): Don't bail out early when reaching
10189 position beyond to_charpos, if we are scanning backwards.
10190 (move_it_vertically_backward): When DY == 0, make sure we get to
10191 the first character in the line after the newline.
10193 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10195 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10196 (ccl_driver): Do not generate an out-of-range pointer.
10197 (Fccl_execute_on_string): Remove unnecessary check for
10198 integer overflow, noted by Stefan Monnier in
10199 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10200 Remove a FIXME that didn't need fixing.
10201 Simplify the newly-introduced buffer reallocation code.
10203 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10205 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10207 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10209 Integer and memory overflow issues (Bug#9196).
10211 * doc.c (get_doc_string): Rework so that
10212 get_doc_string_buffer_size is the actual buffer size, rather than
10213 being 1 less than the actual buffer size; this makes xpalloc more
10216 * image.c (x_allocate_bitmap_record, cache_image):
10217 * xselect.c (Fx_register_dnd_atom):
10218 Simplify previous changes by using xpalloc.
10220 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10221 since either will do and ptrdiff_t is convenient with xpalloc.
10223 * charset.c (charset_table_size)
10224 (struct charset_sort_data.priority): Now ptrdiff_t.
10225 (charset_compare): Don't overflow if priorities differ greatly.
10226 (Fsort_charsets): Don't assume list length fits in int.
10227 Check for size-calculation overflow when allocating sort data.
10228 (syms_of_charset): Allocate an initial charset table that is
10229 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10231 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10233 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10234 The actual value is always <= INT_MAX, and leaving it unsigned made
10235 overflow checking harder.
10237 * dispextern.h (struct glyph_matrix.rows_allocated)
10238 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10239 with xpalloc. The values are still always <= INT_MAX.
10241 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10243 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10244 (SAFE_NALLOCA): New macro.
10246 * region-cache.c (struct boundary.pos, find_cache_boundary)
10247 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10248 (set_cache_region, invalidate_region_cache)
10249 (revalidate_region_cache, know_region_cache, region_cache_forward)
10250 (region_cache_backward, pp_cache):
10251 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10252 so that ptrdiff_t * can be passed to xpalloc.
10253 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
10254 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
10255 (pp_cache): Don't assume cache_len fits in int.
10256 * region-cache.h: Adjust extern decls to match.
10258 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
10259 EMACS_INT, since either will do, for xpalloc.
10261 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
10262 (xnmalloc, xnrealloc, xpalloc): New functions.
10264 * bidi.c (bidi_shelve_header_size): New constant.
10265 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
10266 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
10268 * bidi.c (bidi_cache_shrink):
10269 * buffer.c (overlays_at, overlays_in, record_overlay_string)
10271 Don't update size of array until after memory allocation succeeds,
10272 because xmalloc/xrealloc may not return.
10273 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10274 now that we have proper integer overflow checking.
10275 (record_overlay_string, overlay_strings): Catch overflows when
10276 calculating size of overlay_str_buf.
10278 * callproc.c (Fcall_process): Check for size overflow when
10279 calculating size of args2.
10280 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
10281 Normally we prefer signed values, but sticking with ptrdiff_t would
10282 require adding more-complicated checks.
10284 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10285 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
10286 Redo buffer-overflow calculations to avoid integer overflow.
10287 Add a FIXME comment where memory seems to be over-allocated.
10289 * character.c (Fstring): Check for size-calculation overflow.
10291 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
10292 unnecessary integer overflow. Check for size overflow.
10293 (encode_coding_object): Don't update size until xmalloc succeeds.
10295 * composite.c (get_composition_id): Check for overflow in glyph
10296 length calculations.
10298 Integer and memory overflow fixes for display code.
10299 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
10300 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
10301 (scrolling_window): Check for overflow in size calculations.
10302 (line_draw_cost, realloc_glyph_pool, add_row_entry):
10303 Don't assume glyph table len fits in int.
10304 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
10305 (row_table_size): Now ptrdiff_t, not int.
10306 (scrolling_window): Avoid overflow in size calculations.
10307 Don't update size until allocation succeeds.
10308 * fns.c (concat): Check for overflow in size calculations.
10309 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
10310 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
10311 (NEXT_ALMOST_PRIME_LIMIT): New constant.
10313 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
10314 (get_doc_string): Check for size calculation overflow.
10315 Don't update size until allocation succeeds.
10316 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
10317 EMACS_INT, where ptrdiff_t will do.
10318 (Fsubstitute_command_keys): Check for string overflow.
10320 * editfns.c (set_time_zone_rule): Don't assume environment length
10322 (message_length): Now ptrdiff_t, not int.
10323 (Fmessage_box): Don't update size until allocation succeeds.
10324 Don't assume message length fits in int.
10325 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10327 * emacs.c (main): Do not reallocate argv, since there is a null at
10328 the end that can be overwritten, and this way there's no need to
10329 worry about size-calculation overflow.
10330 (sort_args): Check for size-calculation overflow.
10332 * eval.c (init_eval_once, grow_specpdl): Don't update size until
10334 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
10336 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
10337 (x_set_scroll_bar_width, x_figure_window_size):
10338 Check for integer overflow.
10339 (x_set_alpha): Do not assume XINT fits in int.
10341 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10342 This is for the members text_lines, text_cols, total_lines, total_cols,
10343 where the system imposes an 'int' limit.
10345 * fringe.c (Fdefine_fringe_bitmap):
10346 Don't update size until alloc works.
10348 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
10349 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
10351 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
10352 Check for size-calculation overflow.
10353 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10354 do, as we prefer signed integers.
10355 (id_to_widget.max_size, id_to_widget.used)
10356 (xg_store_widget_in_map, xg_remove_widget_from_map)
10357 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
10358 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
10359 Use and return ptrdiff_t, not int.
10360 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
10361 * gtkutil.h: Change prototypes to match the above.
10363 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
10364 are duplicate now that they've been promoted to lisp.h.
10365 (x_allocate_bitmap_record, x_alloc_image_color)

10408 (Fset_match_data): Don't assume list lengths fit in 'int'.
10410 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
10411 for command line length. Do not attempt to address one before the
10412 beginning of an array, as that's not portable.
10414 * term.c (max_frame_lines): Remove; unused.

10442 Check for size calculation overflow.
10443 (cache_face): Treat size calculation overflows as if they were
10444 memory exhaustion (the usual treatment), rather than aborting.
10446 * xfns.c (x_encode_text, x_set_name_internal)
10447 (Fx_change_window_property): Use ptrdiff_t, not int, to count
10448 sizes, since they can exceed INT_MAX in size. Check for size
10449 calculation overflow.

10452 (xg_select): Check for size calculation overflow.
10453 Don't update size until alloc done.
10455 * xrdb.c (get_environ_db): Don't assume path length fits in int,
10456 as sprintf is limited to int lengths.
10458 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
10459 (X_LONG_MIN): New macros.
10460 Use them to make the following changes clearer.
10461 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
10462 This change doesn't affect the value now, but it may help remind
10463 future maintainers not to raise the value too much later.
10464 (SELECTION_QUANTUM): Remove, replacing with ...
10465 (selection_quantum): ... new function, which avoids overflow.
10467 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10468 assumption that selection length fits in 'int'.

10485 Don't store size until memory allocation succeeds.
10486 (x_get_window_property): Plug memory leak on memory exhaustion.
10487 Don't double-block input; malloc is safe here. Don't assume 2**34
10488 - 4 fits in unsigned long. Add an xassert to check
10489 XGetWindowProperty overflow. Be more careful about overflow
10490 calculations, and distinguish size from memory overflow better.
10491 (receive_incremental_selection): When tracing, don't assume
10492 unsigned int is less than INT_MAX.
10493 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

10497 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10498 result parameters unless successful. Rely on cons_to_unsigned
10499 to report problems with elements; the old code wasn't right anyway.
10500 (x_check_property_data): Check for int overflow; we cannot use
10501 a wider type due to X limits.

10534 * lisp.h (hash_lookup, hash_put):
10535 * minibuf.c (Ftest_completion):
10536 Use ptrdiff_t for hash table indexes, not int (which is too
10537 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
10538 32-bit --with-wide-int hosts).
10540 * charset.c (Fdefine_charset_internal): Check for integer overflow.
10541 Add a FIXME comment about memory leaks.

10569 * xterm.c: Don't go over XClientMessageEvent limit.
10570 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
10571 (x_send_scroll_bar_event): Likewise. Check that the size does not
10572 exceed limits imposed by XClientMessageEvent, as well as the usual
10573 ptrdiff_t and size_t limits.

10576 (make_lispy_movement): Use same integer type in forward decl
10577 that is used in the definition.
10578 (read_key_sequence, keyremap_step):
10579 Change bufsize argument back to int, undoing my 2011-03-30 change.
10580 We prefer signed types, and int is wide enough here.
10581 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
10582 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
10583 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
10584 length, not size_t. Use ptrdiff_t for index, not int.
10585 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
10586 possibility of integer overflow.

10614 Prefer int to unsigned where either will do.
10615 (tiff_handler): New function, combining the cores of the
10616 old tiff_error_handler and tiff_warning_handler.
10617 This function is rewritten to use vsnprintf and thereby avoid
10618 stack buffer overflows. It uses only the features of vsnprintf
10619 that are common to both POSIX and native Microsoft.
10620 (tiff_error_handler, tiff_warning_handler): Use it.
10621 (tiff_load, gif_load, imagemagick_load_image):
10622 Don't assume :index value fits in 'int'.
10623 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
10624 (imagemagick_load_image): Check that crop parameters fit into
10625 the integer types that MagickCropImage accepts. Don't assume
10626 Vimagemagick_render_type has a nonnegative value. Don't assume
10627 size_t fits in 'long'.
10628 (gs_load): Use printmax_t to print the widest integers possible.

10665 buffers, return left-to-right.
10666 (set_cursor_from_row): Consider candidate row a win if its glyph

10668 positioning on the newline at EOL of R2L text within L2R
10669 paragraph, and vice versa.
10670 (try_cursor_movement): Check continued rows, in addition to
10671 continuation rows. Fixes unwarranted scroll when point enters a
10672 continued line of R2L text within an L2R paragraph, or vice versa.
10673 (cursor_row_p): Consider the case of point being equal to
10674 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

10703 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
10704 instead of CHAR_TO_BYTE. Fixes a crash when a completion
10705 candidate is selected by the mouse, and that candidate has a
10706 composed character under the mouse.
10708 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
10709 coordinates reported by pos-visible-in-window-p for a composed
10710 character in column zero.

10719 consider it a hit if to_charpos is anywhere in the range of the
10720 composed buffer positions.
10722 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
10724 * image.c (gif_load): Don't assume that each subimage has the same
10725 dimensions as the base image. Handle disposal method that is
10726 "undefined" by the gif spec (Bug#9335).
10728 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
10730 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

10740 a composition, take its buffer position from IT->cmp_it.charpos.
10741 Fixes cursor positioning at the beginning of a line that begins
10742 with a composed character.
10744 2011-08-18 Eli Zaretskii <eliz@gnu.org>
10746 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
10747 character bidirectional type, use STRONG_L instead. Fixes crashes
10748 in a buffer produced by `describe-categories'.
10750 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
10751 members before the level stack, so they would be saved and
10752 restored when copying iterator state. Fixes incorrect reordering
10753 around TABs covered by display properties.
10755 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

10812 bidi_ignore_explicit_marks_for_paragraph_level.
10813 (bidi_initialize): Use uniprop_table instead of including
10814 biditype.h and bidimirror.h.
10816 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
10817 coordinates of the iterator when restoring from ppos_it.
10820 2011-08-14 Kenichi Handa <handa@m17n.org>
10822 * process.c (create_process): Call setup_process_coding_systems
10823 after the pid of the process is set to -1 (Bug#8162).
10825 2011-08-14 Eli Zaretskii <eliz@gnu.org>
10827 * xdisp.c (move_it_in_display_line_to): Don't invoke
10828 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
10829 ppos_it. Fixes vertical cursor motion when line beginning is
10830 covered by an image. (Bug#9296)
10832 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
10834 * nsterm.h (ns_run_ascript): Declare.
10835 (NSAPP_DATA2_RUNASSCRIPT): Define.
10837 * nsfns.m (as_script, as_result, as_status): New static variables.
10838 (ns_run_ascript): New function.
10839 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
10840 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
10841 the event loop. Get status from as_status (Bug#7276).
10843 * nsterm.m (sendEvent): If event is NSApplicationDefined and
10844 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
10845 the event loop (Bug#7276).
10847 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
10849 * gnutls.c (QCgnutls_bootprop_priority)
10850 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
10851 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
10852 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
10853 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
10854 (QCgnutls_bootprop_verify_hostname_error)
10855 (QCgnutls_bootprop_callbacks_verify): Rename from
10856 Qgnutls_bootprop_..., all uses changed.
10858 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
10861 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
10863 * xfaces.c (Qframe_set_background_mode): Now static.
10864 * dispextern.h (Qframe_set_background_mode): Remove decl.
10866 * process.c (Fnetwork_interface_info): Declare local only if needed.
10868 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
10870 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
10871 (Fnetwork_interface_list): Allocate in increments of bytes instead
10872 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
10873 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
10875 (struct ifflag_def): notrailers is smart on OSX.
10876 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
10877 Get hardware address with getifaddrs if available.
10879 2011-08-12 Eli Zaretskii <eliz@gnu.org>
10881 * xdisp.c (iterate_out_of_display_property): xassert that
10882 IT->position is set to within IT->object's boundaries. Break from
10883 the loop as soon as EOB is reached; avoids infloops in redisplay
10884 when IT->position is set up wrongly due to some bug.
10885 Set IT->current to match the bidi iterator unconditionally.
10886 (push_display_prop): Allow GET_FROM_STRING as IT->method on
10887 entry. Force push_it to save on the stack the current
10888 buffer/string position, to be restored by pop_it. Fix flags in
10889 the iterator structure wrt the object coming from a display
10890 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
10891 properties. (Bug#9284)
10893 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
10895 * fontset.c (fontset_get_font_group): Add proper type checks.
10898 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10900 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
10901 and LC_VERSION_MIN_MACOSX.
10902 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
10903 (dump_it) [LC_FUNCTION_STARTS]: Use it.
10905 2011-08-08 Eli Zaretskii <eliz@gnu.org>
10907 * xdisp.c (forward_to_next_line_start): Allow to use the
10908 no-display-properties-and-no-overlays under bidi display.
10909 Set disp_pos in the bidi iterator to avoid searches for display
10910 properties and overlays.
10912 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
10914 * editfns.c (Fset_time_zone_rule): Document relationship with the
10917 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
10918 the font entity extracted from the cache (Bug#8109).
10920 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
10922 * composite.c (autocmp_chars): Don't reset point. That is done by
10923 restore_point_unwind (Bug#5984).
10925 2011-08-07 Juri Linkov <juri@jurta.org>
10927 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
10928 to show the arg `TIME' instead of `TIMEVAL'.
10930 2011-08-06 Eli Zaretskii <eliz@gnu.org>
10932 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
10933 display property strides EOL and includes a newline, as in
10934 longlines-mode. (Bug#9254)
10935 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
10936 word-wrap under bidirectional display. (Bug#9224)
10938 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
10939 is non-zero, even if the data buffer is NULL. Fixes a crash in
10940 vertical-motion with longlines-mode. (Bug#9254)
10942 2011-08-05 Eli Zaretskii <eliz@gnu.org>
10944 * bidi.c <bidi_cache_total_alloc>: Now static.
10945 (bidi_initialize): Initialize bidi_cache_total_alloc.
10947 * xdisp.c (display_line): Release buffer allocated for shelved bidi
10950 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
10951 amount allocated this far in `bidi_cache_total_alloc'.
10952 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
10953 non-zero, only free the data buffer without restoring the cache
10954 contents. All callers changed.
10956 * dispextern.h (bidi_unshelve_cache): Update prototype.
10958 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
10959 (move_it_in_display_line, move_it_to)
10960 (move_it_vertically_backward, move_it_by_lines): Replace the call
10961 to xfree to an equivalent call to bidi_unshelve_cache.
10962 (move_it_in_display_line_to): Fix logic of returning
10963 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
10965 2011-08-05 Eli Zaretskii <eliz@gnu.org>
10967 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
10968 came from a string character with a `cursor' property. (Bug#9229)
10970 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
10972 * Makefile.in (LIB_PTHREAD): New variable.
10973 (LIBES): Add LIB_PTHREAD (Bug#9216).
10975 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
10976 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
10978 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
10980 * regex.c (re_iswctype): Remove some redundant boolean conversions.
10982 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
10984 * xterm.c (x_find_topmost_parent): New function.
10985 (x_set_frame_alpha): Find topmost parent window with
10986 x_find_topmost_parent and set the property there also (bug#9181).
10987 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
10989 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
10991 * callproc.c (Fcall_process): Avoid vfork clobbering
10992 the local vars buffer, coding_systems, current_dir.
10994 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
10996 * keymap.c (Fmake_composed_keymap): Move to subr.el.
10998 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
11000 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
11001 so that it is not optimized away.
11003 * xdisp.c (compute_display_string_pos): Remove unused local.
11005 2011-08-02 Eli Zaretskii <eliz@gnu.org>
11007 Fix slow cursor motion and scrolling in large buffers with
11008 selective display, like Org Mode buffers. (Bug#9218)
11010 * dispextern.h (struct bidi_it): New member disp_prop_p.
11012 * xdisp.c: Remove one-slot cache of display string positions.
11013 (compute_display_string_pos): Accept an additional argument
11014 DISP_PROP_P; callers changed. Scan at most 5K characters forward
11015 for a display string or property. If found, set DISP_PROP_P
11018 * bidi.c (bidi_fetch_char): Accept an additional argument
11019 DISP_PROP_P, and pass it to compute_display_string_pos.
11020 Only handle text covered by a display string if DISP_PROP_P is returned
11021 non-zero. All callers of bidi_fetch_char changed.
11023 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
11025 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
11027 2010-12-03 Don March <don@ohspite.net>
11029 * keymap.c (Fdefine_key): Fix non-prefix key error message when
11030 last character M-[char] is translated to ESC [char] (bug#7541).
11032 2011-08-02 Kenichi Handa <handa@m17n.org>
11034 * lisp.h (uniprop_table): Extern it.
11036 * chartab.c (uniprop_table): Make it non-static.
11038 2011-08-01 Eli Zaretskii <eliz@gnu.org>
11040 * xdisp.c (forward_to_next_line_start): Accept additional argument
11041 BIDI_IT_PREV, and store into it the state of the bidi iterator had
11043 (reseat_at_next_visible_line_start): Use the bidi iterator state
11044 returned by forward_to_next_line_start to restore the state of
11045 it->bidi_it after backing up to previous newline. (Bug#9212)
11047 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
11049 * regex.c (re_comp): Protoize.
11050 (re_exec): Fix return type.
11051 (regexec): Fix type of `ret'. (Bug#9203)
11053 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11055 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
11056 This is needed if max-image-size is a floating-point number.
11058 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11060 * print.c (print_object): Print empty symbol as ##.
11062 * lread.c (read1): Read ## as empty symbol.
11064 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11066 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
11067 setting frame foreground color (Bug#9175).
11068 (x_set_background_color): Likewise.
11070 * nsmenu.m (-setText): Size tooltip dimensions precisely to
11071 contents (Bug#9176).
11072 (EmacsTooltip -init): Remove bezels and add shadows to
11075 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
11076 or scroll bar (Bug#8470).
11078 * nsfont.m (nsfont_open): Remove assignment to voffset and
11079 unnecessary vars hshink, expand, hd, full_height, min_height.
11080 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
11082 * nsterm.h (nsfont_info): Remove voffset field.
11084 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11086 Implement strike-through and overline on NextStep (Bug#8863).
11088 * nsfont.m (nsfont_open): Use underline position provided by font,
11089 instead of hard-coded value of 2.
11090 (nsfont_draw): Call ns_draw_text_decoration instead.
11092 * nsterm.h: Add declaration for ns_draw_text_decoration.
11094 * nsterm.m (ns_draw_text_decoration): New function for drawing
11095 underline, overline, and strike-through.
11096 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
11097 ns_draw_text_decoration. Change treatment of cursor drawing to
11098 accommodate underlining, etc.
11100 2011-07-28 Eli Zaretskii <eliz@gnu.org>
11102 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
11105 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11107 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11108 Without this fix, if a signal arrives just after memory fills up,
11109 'malloc' might be invoked reentrantly.
11111 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11112 In other words, assume that every image size is allowed, on non-X
11113 hosts. This assumption is probably wrong, but it lets Emacs compile.
11115 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11117 * regex.c (re_iswctype): Convert return values to boolean.
11119 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
11121 * xdisp.c (compute_display_string_pos): Don't use cached display
11122 string position if the buffer had its restriction changed.
11125 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11127 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11129 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11131 Integer signedness and overflow and related fixes. (Bug#9079)
11133 * bidi.c: Integer size and overflow fixes.
11134 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
11135 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
11136 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11137 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11138 (bidi_find_other_level_edge):
11139 Use ptrdiff_t instead of EMACS_INT where either will do.
11140 This works better on 32-bit hosts configured --with-wide-int.
11141 (bidi_cache_ensure_space): Check for size-calculation overflow.
11142 Use % rather than repeated addition, for better worst-case speed.
11143 Don't set bidi_cache_size until after xrealloc returns, because it
11145 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11146 (bidi_cache_ensure_space): Also check that the bidi cache size
11147 does not exceed that of the largest Lisp string or buffer. See Eli
11148 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11150 * alloc.c (__malloc_size_t): Remove.
11151 All uses replaced by size_t. See Andreas Schwab's note
11152 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11154 * image.c: Improve checking for integer overflow.
11155 (check_image_size): Assume that f is nonnull, since
11156 it is always nonnull in practice. This is one less thing to
11157 worry about when checking for integer overflow later.
11158 (x_check_image_size): New function, which checks for integer
11159 overflow issues inside X.
11160 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11161 This removes the need for a memory_full check.
11162 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11163 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11164 (xbm_read_bitmap_data): Change locals back to 'int', since
11165 their values must fit in 'int'.
11166 (xpm_load_image, png_load, tiff_load):
11167 Invoke x_create_x_image_and_pixmap earlier,
11168 to avoid much needless work if the image is too large.
11169 (tiff_load): Treat overly large images as if
11170 x_create_x_image_and_pixmap failed, not as malloc failures.
11171 (gs_load): Use x_check_image_size.
11173 * gtkutil.c: Omit integer casts.
11174 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11175 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11177 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11179 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11180 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11181 would wrongly return t on a 64-bit host.
11183 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11184 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11185 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11186 and therefore cause GCC to emit a bogus diagnostic in some cases.
11188 * image.c: Integer signedness and overflow and related fixes.
11189 This is not an exhaustive set of fixes, but it's time to
11190 record what I've got.
11191 (lookup_pixel_color, check_image_size): Remove redundant decls.
11192 (check_image_size): Don't assume that arbitrary EMACS_INT values
11193 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11194 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11195 (tiff_load, imagemagick_load_image):
11196 Check for overflow in size calculations.
11197 (x_create_x_image_and_pixmap): Remove unnecessary test for
11198 xmalloc returning NULL; that can't happen.
11199 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11200 (xpm_color_bucket): Use better integer hashing function.
11201 (xpm_cache_color): Don't possibly over-allocate memory.
11202 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11203 (gif_memory_source):
11204 Use ptrdiff_t, not int or size_t, to record sizes.
11205 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11206 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11207 either works, as we prefer signed integers.
11208 (tiff_read_from_memory, tiff_write_from_memory):
11209 Return tsize_t, not size_t, since that's what the TIFF API wants.
11210 (tiff_read_from_memory): Don't fail simply because the read would
11211 go past EOF; instead, return a short read.
11212 (tiff_load): Omit no-longer-needed casts.
11213 (Fimagemagick_types): Don't assume size fits into 'int'.
11215 Improve hashing quality when configured --with-wide-int.
11216 * fns.c (hash_string): New function, taken from sxhash_string.
11217 Do not discard information about ASCII character case; this
11218 discarding is no longer needed.
11219 (sxhash-string): Use it. Change sig to match it. Caller changed.
11220 * lisp.h: Declare it.
11221 * lread.c (hash_string): Remove, since we now use fns.c's version.
11222 The fns.c version returns a wider integer if --with-wide-int is
11223 specified, so this should help the quality of the hashing a bit.
11225 * emacs.c: Integer overflow minor fix.
11226 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11227 Define only if GNU_LINUX.
11228 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11230 * dispnew.c: Integer signedness and overflow fixes.
11231 Remove unnecessary forward decls, that were a maintenance hassle.
11232 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11234 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11235 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11236 (prepare_desired_row, line_draw_cost):
11237 Use int, not unsigned, where either works.
11238 (save_current_matrix, restore_current_matrix):
11239 Use ptrdiff_t, not size_t, where either works.
11240 (init_display): Check for overflow more accurately, and without
11241 relying on undefined behavior.
11243 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11244 Remove, replacing with the new symbols in lisp.h. All uses changed.
11245 * fileio.c (make_temp_name):
11246 * filelock.c (lock_file_1, lock_file):
11247 * xdisp.c (message_dolog):
11248 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11249 Use pMd etc. instead.
11250 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11251 replacing the pWIDE etc. symbols removed from editfns.c.
11253 * keyboard.h (num_input_events): Now uintmax_t.
11254 This is (very slightly) less likely to mess up due to wraparound.
11257 * buffer.c: Integer signedness fixes.
11258 (alloc_buffer_text, enlarge_buffer_text):
11259 Use ptrdiff_t rather than size_t when either will do, as we prefer
11262 * alloc.c: Integer signedness and overflow fixes.
11263 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11264 (__malloc_size_t): Default to size_t, not to int.
11265 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11266 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11267 Prefer ptrdiff_t to size_t when either would do, as we prefer
11269 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11270 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11271 Now const. Initialize with values that are in range even if char
11273 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11274 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11275 These functions do the right thing with sizes > 2**32.
11276 (check_depth): Now ptrdiff_t, not int.
11277 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11278 Adjust to new way of storing sizes. Check for size overflow bugs
11280 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11281 slightly wrong anyway, as it missed one instance of
11282 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11283 (refill_memory_reserve): Omit needless cast to size_t.
11284 (mark_object_loop_halt): Mark as externally visible.
11286 * xselect.c: Integer signedness and overflow fixes.
11287 (Fx_register_dnd_atom, x_handle_dnd_message):
11288 Use ptrdiff_t, not size_t, since we prefer signed.
11289 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11290 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11291 x_dnd_atoms_size and x_dnd_atoms_length.
11293 * doprnt.c: Prefer signed to unsigned when either works.
11295 * doprnt.c (doprnt):
11297 * xdisp.c (vmessage):
11298 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11299 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11300 prefer signed arithmetic to avoid comparison confusion.
11301 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11302 but is a bit tricky.
11304 Assume freestanding C89 headers, string.h, stdlib.h.
11305 * data.c, doprnt.c, floatfns.c, print.c:
11306 Include float.h unconditionally.
11307 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11308 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11309 * regex.c: Likewise for stddef.h, string.h.
11310 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11311 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11312 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11313 (STDC_HEADERS): Remove obsolete defines.
11314 * sysdep.c: Include limits.h unconditionally.
11316 Assume support for memcmp, memcpy, memmove, memset.
11317 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11318 * regex.c (memcmp, memcpy):
11319 Remove; we assume C89 now.
11321 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11322 (__malloc_safe_bcopy): Remove; no longer needed.
11324 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11325 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11326 well either way, and we prefer signed to unsigned.
11328 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11330 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11331 closes the connection while we're reading (bug#9182).
11333 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11335 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11336 are specified (Bug#9168).
11338 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11340 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11341 Found by GCC static checking and --with-wide-int on a 32-bit host.
11343 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11345 * xdisp.c (compute_display_string_pos): Fix logic of caching
11346 previous display string position. Initialize cached_prev_pos to
11347 -1. Fixes slow-down at the beginning of a buffer.
11349 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11351 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11352 for attrs[LFACE_FONTSET_INDEX].
11354 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11356 * xml.c (parse_region): Remove unused local
11357 that was recently introduced.
11359 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11361 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11362 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11364 * xdisp.c (move_it_in_display_line_to): Record the best matching
11365 position for TO_CHARPOS while scanning the line, and restore it on
11366 exit if none of the characters scanned was an exact match.
11367 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11368 when exact match is impossible due to invisible text, and the
11369 lines are truncated.
11371 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11373 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11376 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11378 Fix a significant slow-down of cursor motion with C-n, C-p,
11379 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11380 auto-repeat under bidi redisplay in fontified buffers.
11381 * xdisp.c (compute_stop_pos_backwards): New function.
11382 (next_element_from_buffer): Call compute_stop_pos_backwards to
11383 find a suitable prev_stop when we find ourselves before
11385 (reseat): Don't look for prev_stop, as that could mean a very long
11387 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11388 <cached_disp_overlay_modiff>: Cache for last found display string
11390 (compute_display_string_pos): Return the cached position if asked
11391 about the same buffer in the same area of character positions, and
11392 the buffer wasn't changed since the time the display string
11393 position was cached.
11395 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11397 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11398 is an integer, which is important for empty lines. (Bug#9149)
11400 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11402 * frame.c (Fmodify_frame_parameters): In tty case, update the
11403 default face if necessary (Bug#4238).
11405 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11407 * editfns.c (Fstring_to_char): No need to explain what a character
11408 is in the docstring (Bug#6576).
11410 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11412 * xml.c (parse_region): Make sure we always return a tree.
11414 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11416 * xml.c (parse_region): If a document contains only comments,
11419 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11421 * xml.c (make_dom): Return comments, too.
11423 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11426 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11427 and the surrounding thread.
11428 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11429 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11430 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11432 * s/openbsd.h (BROKEN_SIGIO): Define.
11433 * unexelf.c (unexec) [__OpenBSD__]:
11434 Don't update the .mdebug section of the Alpha COFF symbol table.
11436 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11438 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11441 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11443 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11444 This fixes some race conditions on the permissions of any newly
11447 * alloc.c (valid_pointer_p): Use pipe, not open.
11448 This fixes some permissions issues when debugging.
11450 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11451 If fchown fails to set both uid and gid, try to set just gid,
11452 as that is sometimes allowed. Adjust the file's mode to eliminate
11453 setuid or setgid bits that are inappropriate if fchown fails.
11455 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11457 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11458 to compare Lisp_Objects.
11459 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11460 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11461 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11463 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11465 * lread.c (read_integer): Unread even EOF character.
11466 (read1): Likewise. Properly record start position of symbol.
11468 * lread.c (read1): Read `#:' as empty uninterned symbol if no
11469 symbol character follows.
11471 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11473 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11474 This works around a problem with the previous change to Fcopy_file.
11475 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11476 and without this change, GCC might complain about discarding
11477 fchown's return value.
11479 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11481 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11483 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11485 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11487 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11489 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11490 it's used from the C level.
11492 * process.c: Use the same condition for POLL_FOR_INPUT in both
11493 keyboard.c and process.c (bug#1858).
11495 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11497 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11498 (Fgnutls_boot): Use it.
11500 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11502 * doc.c (Fsubstitute_command_keys): Revert last change.
11504 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11506 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11507 quotes the next character, and doesn't affect other longer
11508 sequences (bug#8935).
11510 * lread.c (syms_of_lread): Clarify that is isn't only
11511 `eval-buffer' and `eval-defun' that's affected by
11512 `lexical-binding' (bug#8460).
11514 2011-07-15 Eli Zaretskii <eliz@gnu.org>
11516 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11517 bidi redisplay when a line includes both an image and is truncated.
11519 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11521 Fix minor problems found by static checking.
11522 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11523 (elsz): Now a signed constant, not a size_t var. We prefer signed
11524 types to unsigned, to avoid integer comparison confusion. Without
11525 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
11526 "cannot optimize loop, the loop counter may overflow", a symptom
11528 * indent.c (Fvertical_motion): Mark locals as initialized.
11529 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
11531 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
11533 * search.c (Fre_search_backward): Mention `case-fold-search' in
11534 all the re_search_* functions (bug#8138).
11536 * keyboard.c (Fopen_dribble_file): Document when the file is

11547 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
11548 (reseat_to_string): Initialize bidi_it->string.s and
11549 bidi_it->string.schars.
11550 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
11551 NULL (avoids a crash in bidi_paragraph_init).
11552 Initialize itb.string.lstring.
11553 (init_iterator): Call bidi_init_it only of a valid
11554 buffer position was specified. Initialize paragraph_embedding to
11556 (reseat_to_string): Initialize the bidi iterator.
11557 (display_string): If we need to ignore text properties of
11558 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
11559 original value of -1 will not work with bidi.)
11560 (compute_display_string_pos): First arg is now struct
11561 `text_pos *'; all callers changed. Support display properties on
11563 (compute_display_string_end): Support display properties on Lisp
11565 (init_iterator, reseat_1, reseat_to_string): Initialize the
11566 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
11567 when iterating on a string not from display properties).
11568 (compute_display_string_pos, compute_display_string_end):
11569 Fix calculation of the object to scan. Fixes an error when using
11571 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
11572 base_level_stop; instead, set base_level_stop to BEGV.
11573 Fixes crashes in vertical-motion.
11574 (next_element_from_buffer): Improve commentary for when
11575 the iterator is before prev_stop.
11576 (init_iterator): Initialize bidi_p from the default value of
11577 bidi-display-reordering, not from buffer-local value. Use the
11578 buffer-local value only if initializing for buffer iteration.
11579 (handle_invisible_prop): Support invisible properties on strings
11580 that are being bidi-reordered.
11581 (set_iterator_to_next): Support bidi reordering of C strings and
11583 (next_element_from_string): Support bidi reordering of Lisp
11585 (handle_stop_backwards): Support Lisp strings as well.
11586 (display_string): Support display of R2L glyph rows.
11587 Use IT_STRING_CHARPOS when displaying from a Lisp string.
11588 (init_iterator): Don't initialize it->bidi_p for strings
11590 (reseat_to_string): Initialize it->bidi_p for strings here.
11591 (next_element_from_string, next_element_from_c_string)
11592 (next_element_from_buffer): Add xassert's for correspondence
11593 between IT's object being iterated and it->bidi_it.string
11595 (face_before_or_after_it_pos): Support bidi iteration.
11596 (next_element_from_c_string): Handle the case of the first string
11597 character that is not the first one in the visual order.
11598 (get_visually_first_element): New function, refactored from common
11599 parts of next_element_from_buffer, next_element_from_string, and
11600 next_element_from_c_string.
11601 (tool_bar_lines_needed, redisplay_tool_bar)
11602 (display_menu_bar): Force left-to-right direction. Add a FIXME
11603 comment for making that be controlled by a user option.
11604 (push_it, pop_it): Save and restore the state of the
11605 bidi iterator. Save and restore the bidi_p flag.
11606 (pop_it): Iterate out of display property for string iteration as
11608 (iterate_out_of_display_property): Support iteration over strings.
11609 (handle_single_display_spec): Set up it->bidi_it for iteration
11610 over a display string, and call bidi_init_it.
11611 (handle_single_display_spec, next_overlay_string)
11612 (get_overlay_strings_1, push_display_prop): Set up the bidi
11613 iterator for displaying display or overlay strings.
11614 (forward_to_next_line_start): Don't use the shortcut if
11616 (back_to_previous_visible_line_start): If handle_display_prop
11617 pushed the iterator stack, restore the internal state of the bidi
11618 iterator by calling bidi_pop_it same number of times.
11619 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
11620 and we are bidi-iterating, don't decrement the iterator position;
11621 instead, set the first_elt flag in the bidi iterator, to produce
11623 (reseat_1): Remove redundant setting of string_from_display_prop_p.
11624 (push_display_prop): xassert that we are iterating a buffer.
11625 (push_it, pop_it): Save and restore paragraph_embedding member.
11626 (handle_single_display_spec, next_overlay_string)
11627 (get_overlay_strings_1, reseat_1, reseat_to_string)
11628 (push_display_prop): Set up the `unibyte' member of bidi_it.string
11629 correctly. Don't assume unibyte strings are not bidi-reordered.
11630 (compute_display_string_pos)
11631 (compute_display_string_end): Fix handling the case of C string.
11632 (push_it, pop_it): Save and restore from_disp_prop_p.
11633 (handle_single_display_spec, push_display_prop): Set the
11634 from_disp_prop_p flag.
11635 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
11636 (pop_it): Call iterate_out_of_display_property only if we are
11637 popping after iteration over a string that came from a display
11638 property. Fix a typo in popping stretch info. Add an assertion
11639 for verifying that the iterator position is in sync with the bidi
11641 (handle_single_display_spec, get_overlay_strings_1)
11642 (push_display_prop): Fix initialization of paragraph direction for
11643 string when that of the parent object is not yet determined.
11644 (reseat_1): Call bidi_init_it to resync the bidi
11645 iterator with IT's position. (Bug#7616)
11646 (find_row_edges): If ROW->start.pos gives position
11647 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
11648 (handle_stop, back_to_previous_visible_line_start, reseat_1):
11649 Reset the from_disp_prop_p flag.
11650 (SAVE_IT, RESTORE_IT): New macros.
11651 (pos_visible_p, face_before_or_after_it_pos)
11652 (back_to_previous_visible_line_start)
11653 (move_it_in_display_line_to, move_it_in_display_line)
11654 (move_it_to, move_it_vertically_backward, move_it_by_lines)
11655 (try_scrolling, redisplay_window, display_line): Use them when
11656 saving a temporary copy of the iterator and restoring it back.
11657 (back_to_previous_visible_line_start, reseat_1)
11658 (init_iterator): Empty the bidi cache "stack".
11659 (move_it_in_display_line_to): If iterator ended up at
11660 EOL, but we never saw any buffer positions smaller than
11661 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
11662 motion in bidi-reordered lines.
11663 (move_it_in_display_line_to): Record prev_method and prev_pos
11664 immediately before the call to set_iterator_to_next. Fixes cursor
11665 motion in bidi-reordered lines with stretch glyphs and strings
11666 displayed in margins. (Bug#8133) (Bug#8867)
11667 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
11669 (pos_visible_p): Support positions in bidi-reordered lines.
11670 Save and restore bidi cache.
11672 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
11673 (bidi_paragraph_info): Delete unused struct.
11674 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
11675 (bidi_cache_start): New variable.
11676 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
11678 (bidi_cache_fetch_state, bidi_cache_search)
11679 (bidi_cache_find_level_change, bidi_cache_iterator_state)
11680 (bidi_cache_find, bidi_peek_at_next_level)

11684 (bidi_fetch_char): Accept new argument STRING; all callers
11685 changed. Support iteration over a string. Support strings with
11686 display properties. Support unibyte strings. Fix the type of
11687 `len' according to what STRING_CHAR_AND_LENGTH expects.
11688 (bidi_paragraph_init, bidi_resolve_explicit_1)
11689 (bidi_resolve_explicit, bidi_resolve_weak)
11690 (bidi_level_of_next_char, bidi_move_to_visually_next):

11785 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
11786 The old code sometimes used this field without initializing it.
11788 * alloc.c (gc_sweep): Don't read past end of array.
11789 In theory, the old code could also have corrupted Emacs internals,
11790 though it'd be very unlikely.

12053 (clone_per_buffer_values): Don't assume that
12054 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
12055 This isn't true in general, and it's particularly not true
12056 if Emacs is configured with --with-wide-int.
12057 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
12058 New macros, used in the buffer.c change.

12094 Random fixes. E.g., (random) never returned negative values.
12095 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
12096 subseconds part to the entropy, as that's a bit more random.
12097 Prefer signed to unsigned, since the signedness doesn't matter and
12098 in general we prefer signed. When given a limit, use a
12099 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12100 latter isn't right if USE_2_TAGS_FOR_INTS.
12101 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12102 not 0..VALMASK. Don't discard "excess" bits that random () returns.

12112 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
12114 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
12115 This is more efficient than Ffile_directory_p and avoids a minor race.
12117 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
12119 * buffer.c (Foverlay_put): Say what the return value is
12122 * fileio.c (barf_or_query_if_file_exists): Check first if the file
12123 is a directory before asking whether to use the file name
12125 (barf_or_query_if_file_exists): Make the "File is a directory"
12126 error be more correct.
12128 * fns.c (Frequire): Remove the mention of the .gz files, since
12129 that's installation-specific, but keep the mention of
12130 `get-load-suffixes'.
12132 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>

12247 * eval.c (struct backtrace): Simplify and port the data structure.
12248 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12249 signed bit field, as this assumption is not portable and it makes
12250 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12251 "char debug_on_exit : 1" as this is not portable either; instead,
12252 use the portable "unsigned int debug_on_exit : 1". Remove unused
12253 member evalargs. Remove obsolete comments about cc bombing out.

12489 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12490 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12491 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12492 since we're not interested in debugging glyphs with old libraries.
12493 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12494 GCC 4.6.0's static checking.

12536 (x_session_initialize): Do not assume string length fits in int.
12538 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

12576 Don't assume integer property fits in fixnum.
12577 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
12579 * filelock.c: Fix some buffer overrun and integer overflow issues.
12580 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
12581 Reformulate so as not to need the command string.
12582 Invoke gzip -cd rather than gunzip, as it's more portable.
12583 (lock_info_type, lock_file_1, lock_file):
12584 Don't assume pid_t and time_t fit in unsigned long.
12585 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
12586 (current_lock_owner): Prefer signed type for sizes.
12587 Use memcpy, not strncpy, where memcpy is what is really wanted.
12588 Don't assume (via atoi) that time_t and pid_t fit in int.
12589 Check for time_t and/or pid_t out of range, e.g., via a network share.
12590 Don't alloca where an auto var works fine.
12592 * fileio.c: Fix some integer overflow issues.
12593 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
12594 Don't assume string length fits in int.
12595 (directory_file_name): Don't assume string length fits in long.
12596 (make_temp_name): Don't assume pid fits in int, or that its print
12597 length is less than 20.
12599 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
12601 * coding.c (make_subsidiaries): Don't assume string length fits in int.
12603 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
12605 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
12606 We prefer signed integers, even for size calculations.
12608 * emacs.c: Don't assume string length fits in 'int'.
12609 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
12610 (main): Don't invoke strlen when not needed.
12612 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
12613 (XD_DEBUG_MESSAGE): Don't waste a byte.
12615 * callproc.c (getenv_internal_1, getenv_internal)
12616 (Fgetenv_internal):
12617 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
12619 * lread.c (invalid_syntax): Omit length argument.
12620 All uses changed. This doesn't fix a bug, but it simplifies the
12621 code away from its former Hollerith-constant appearance, and it's
12622 one less 'int' to worry about when looking at integer-overflow issues.
12623 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
12625 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
12626 This didn't break anything, but it didn't help either.
12627 It's confusing to put a bogus integer in a place where the actual
12628 value does not matter.
12629 (LIST_END_P): Remove unused macro and its bogus comment.
12630 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
12632 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
12633 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
12635 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
12636 We prefer signed types, and the value cannot exceed the EMACS_INT
12637 range anyway (because otherwise the length would not be representable).
12638 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
12639 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
12640 This avoids a GCC warning when WIDE_EMACS_INT.
12642 * indent.c (sane_tab_width): New function.
12643 (current_column, scan_for_column, Findent_to, position_indentation)
12644 (compute_motion): Use it. This is just for clarity.
12645 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
12647 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
12649 * lisp.h (lint_assume): New macro.
12650 * composite.c (composition_gstring_put_cache):
12651 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
12653 * editfns.c, insdel.c:
12654 Omit unnecessary forward decls, to simplify future changes.
12656 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
12658 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
12660 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
12661 Use much-faster test for byte-length change.
12662 Don't assume string byte-length fits in 'int'.
12663 Check that character arg fits in 'int'.
12664 (mapcar1): Declare byte as byte, for clarity.
12666 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
12668 * fns.c (concat): Catch string overflow earlier.
12669 Do not rely on integer wraparound.
12671 * dispextern.h (struct it.overlay_strings_charpos)
12672 (struct it.selective): Now EMACS_INT, not int.
12673 * xdisp.c (forward_to_next_line_start)
12674 (back_to_previous_visible_line_start)
12675 (reseat_at_next_visible_line_start, next_element_from_buffer):
12676 Don't arbitrarily truncate the value of 'selective' to int.
12678 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
12680 * composite.c: Don't truncate sizes to 'int'.
12681 (composition_gstring_p, composition_reseat_it)
12682 (composition_adjust_point): Use EMACS_INT, not int.
12683 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
12684 not EMACS_UINT, for indexes.
12686 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
12688 * buffer.c: Include <verify.h>.
12689 (struct sortvec.priority, struct sortstr.priority):
12690 Now EMACS_INT, not int.
12691 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
12692 (struct sortstr.size, record_overlay_string)
12693 (struct sortstrlist.size, struct sortlist.used):
12694 Don't truncate size to int.
12695 (record_overlay_string): Check for size-calculation overflow.
12696 (init_buffer_once): Check at compile-time, not run-time.
12698 2011-06-22 Jim Meyering <meyering@redhat.com>
12700 Don't leak an XBM-image-sized buffer
12701 * image.c (xbm_load): Free the image buffer after using it.
12703 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
12706 * composite.c (find_automatic_composition): Omit needless 'return 0;'
12707 that Sun C diagnosed.
12708 * fns.c (secure_hash): Fix pointer signedness issue.
12709 * intervals.c (static_offset_intervals): New function.
12710 (offset_intervals): Use it.
12712 2011-06-21 Leo Liu <sdl.web@gmail.com>
12715 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
12718 * fns.c (secure_hash): Rename from crypto_hash_function and change
12719 the first arg to accept symbols.
12720 (Fsecure_hash): New primitive.
12721 (syms_of_fns): New symbols.
12723 2011-06-20 Deniz Dogan <deniz@dogan.se>
12725 * process.c (Fset_process_buffer): Clarify return value in
12728 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
12730 * dispnew.c (add_window_display_history): Use BVAR.
12732 * xdisp.c (debug_method_add): Use BVAR.
12733 (check_window_end, dump_glyph_matrix, dump_glyph)
12734 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
12736 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
12739 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
12740 check till after the cache is created in init_frame_faces.
12742 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
12744 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
12746 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
12748 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
12749 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
12750 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
12752 Improve buffer-overflow checking (Bug#8873).
12753 * fileio.c (Finsert_file_contents):
12754 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
12755 Remove the old (too-loose) buffer overflow checks.
12756 They weren't needed, since make_gap checks for buffer overflow.
12757 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
12758 The old code merely checked for Emacs fixnum overflow, and relied
12759 on undefined (wraparound) behavior. The new code avoids undefined
12760 behavior, and also checks for ptrdiff_t and/or size_t overflow.
12762 * editfns.c (Finsert_char): Don't dump core with very negative counts.
12763 Tune. Don't use wider integers than needed. Don't use alloca.
12764 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
12766 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
12768 * insdel.c, lisp.h (buffer_overflow): New function.
12769 (insert_from_buffer_1, replace_range, replace_range_2):
12770 * insdel.c (make_gap_larger):
12771 * editfns.c (Finsert_char):
12772 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
12774 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
12776 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
12778 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
12780 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
12781 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
12783 * fileio.c: Don't assume EMACS_INT fits in off_t.
12784 (emacs_lseek): New static function.
12785 (Finsert_file_contents, Fwrite_region): Use it.
12786 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
12788 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
12790 * fns.c: Don't overflow int when computing a list length.
12791 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
12792 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
12793 truncation on 64-bit hosts. Check for QUIT every
12794 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
12795 faster and is responsive enough.
12796 (Flength): Report an error instead of overflowing an integer.
12797 (Fsafe_length): Return a float if the value is not representable
12798 as a fixnum. This shouldn't happen except in contrived situations.
12799 (Fnthcdr, Fsort): Don't assume list length fits in int.
12800 (Fcopy_sequence): Don't assume vector length fits in int.
12802 * alloc.c: Check that resized vectors' lengths fit in fixnums.
12803 (header_size, word_size): New constants.
12804 (allocate_vectorlike): Don't check size overflow here.
12805 (allocate_vector): Check it here instead, since this is the only
12806 caller of allocate_vectorlike that could cause overflow.
12807 Check that the new vector's length is representable as a fixnum.
12809 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
12810 The previous code was bogus. For example, next_almost_prime (32)
12811 returned 39, which is undesirable as it is a multiple of 3; and
12812 next_almost_prime (24) returned 25, which is a multiple of 5 so
12813 why was the code bothering to check for multiples of 7?
12815 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
12817 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
12819 Variadic C functions now count arguments with ptrdiff_t.
12820 This partly undoes my 2011-03-30 change, which replaced int with size_t.
12821 Back then I didn't know that the Emacs coding style prefers signed int.
12822 Also, in the meantime I found a few more instances where arguments
12823 were being counted with int, which may truncate counts on 64-bit
12824 machines, or EMACS_INT, which may be unnecessarily wide.
12825 * lisp.h (struct Lisp_Subr.function.aMANY)
12826 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
12827 Arg counts are now ptrdiff_t, not size_t.
12828 All variadic functions and their callers changed accordingly.
12829 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
12830 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
12831 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
12832 * callint.c (Fcall_interactively): Check arg count for overflow,
12833 to avoid potential buffer overrun. Use signed char, not 'int',
12834 for 'varies' array, so that we needn't bother to check its size
12835 calculation for overflow.
12836 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
12837 * eval.c (apply_lambda):
12838 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
12839 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
12840 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
12842 * callint.c (Fcall_interactively): Don't use index var as event count.
12844 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
12845 * mem-limits.h (SIZE): Remove; no longer used.
12847 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
12849 Remove unnecessary casts.
12850 * xterm.c (x_term_init):
12851 * xfns.c (x_set_border_pixel):
12852 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
12853 These aren't needed now that we assume ANSI C.
12855 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
12856 It's more likely to cause problems (due to unsigned overflow)
12859 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
12861 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
12863 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
12865 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
12867 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
12869 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
12871 GLYPH_CODE_FACE returns EMACS_INT, not int.
12872 * dispextern.h (merge_faces):
12873 * xfaces.c (merge_faces):
12874 * xdisp.c (get_next_display_element, next_element_from_display_vector):
12875 Don't assume EMACS_INT fits in int.
12877 * character.h (CHAR_VALID_P): Remove unused parameter.
12878 * fontset.c, lisp.h, xdisp.c: All uses changed.
12880 * editfns.c (Ftranslate_region_internal): Omit redundant test.
12882 * fns.c (concat): Minor tuning based on overflow analysis.
12883 This doesn't fix any bugs. Use int to hold character, instead
12884 of constantly refetching from Emacs object. Use XFASTINT, not
12885 XINT, for value known to be a character. Don't bother comparing
12886 a single byte to 0400, as it's always less.
12888 * floatfns.c (Fexpt):
12889 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
12891 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
12894 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
12896 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
12897 Without this fix, on a 64-bit host (aset S 0 4294967386) would
12898 incorrectly succeed when S was a string, because 4294967386 was
12899 truncated before it was used.
12901 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
12902 Otherwise, an out-of-range integer could cause undefined behavior
12905 * composite.c: Use int, not EMACS_INT, for characters.
12906 (fill_gstring_body, composition_compute_stop_pos): Use int, not
12907 EMACS_INT, for values that are known to be in character range.
12908 This doesn't fix any bugs but is the usual style inside Emacs and
12909 may generate better code on 32-bit machines.
12911 Make sure a 64-bit char is never passed to ENCODE_CHAR.
12912 This is for reasons similar to the recent CHAR_STRING fix.
12913 * charset.c (Fencode_char): Check that character arg is actually
12914 a character. Pass an int to ENCODE_CHAR.
12915 * charset.h (ENCODE_CHAR): Verify that the character argument is no
12916 wider than 'int', as a compile-time check to prevent future regressions
12919 * character.c (char_string): Remove unnecessary casts.
12921 Make sure a 64-bit char is never passed to CHAR_STRING.
12922 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
12923 by silently ignoring the top 32 bits, allowing some values
12924 that were far too large to be valid characters.
12925 * character.h: Include <verify.h>.
12926 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
12927 arguments are no wider than unsigned, as a compile-time check
12928 to prevent future regressions in this area.
12930 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
12931 (Fsubst_char_in_region):
12933 * xdisp.c (decode_mode_spec_coding):
12934 Adjust to CHAR_STRING's new requirement.
12935 * editfns.c (Finsert_char, Fsubst_char_in_region):
12936 * fns.c (concat): Check that character args are actually
12937 characters. Without this test, these functions did the wrong
12938 thing with wildly out-of-range values on 64-bit hosts.
12940 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
12941 These casts should not be needed on 32-bit hosts, either.
12942 * keyboard.c (read_char):
12943 * lread.c (Fload): Remove casts to unsigned.
12945 * lisp.h (UNSIGNED_CMP): New macro.
12946 This fixes comparison bugs on 64-bit hosts.
12947 (ASCII_CHAR_P): Use it.
12948 * casefiddle.c (casify_object):
12949 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
12950 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
12951 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
12952 * dispextern.h (FACE_FROM_ID):
12953 * keyboard.c (read_char): Use UNSIGNED_CMP.
12955 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
12956 not to EMACS_INT, to avoid GCC warning.
12958 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
12960 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
12961 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
12962 isn't needed on 32-bit machines.
12964 * buffer.c (Fgenerate_new_buffer_name):
12965 Use EMACS_INT for count, not int.
12966 (advance_to_char_boundary): Return EMACS_INT, not int.
12968 * data.c (Qcompiled_function): Now static.
12970 * window.c (window_body_lines): Now static.
12972 * image.c (gif_load): Rename local to avoid shadowing.
12974 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
12975 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
12976 * alloc.c (make_save_value): Integer argument is now of type
12977 ptrdiff_t, not int.
12978 (mark_object): Use ptrdiff_t, not int.
12979 * lisp.h (pD): New macro.
12980 * print.c (print_object): Use it.
12982 * alloc.c: Use EMACS_INT, not int, to count objects.
12983 (total_conses, total_markers, total_symbols, total_vector_size)
12984 (total_free_conses, total_free_markers, total_free_symbols)
12985 (total_free_floats, total_floats, total_free_intervals)
12986 (total_intervals, total_strings, total_free_strings):
12987 Now EMACS_INT, not int. All uses changed.
12988 (Fgarbage_collect): Compute overall total using a double, so that
12989 integer overflow is less likely to be a problem. Check for overflow
12990 when converting back to an integer.
12991 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
12992 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
12993 These were 'int' variables that could overflow on 64-bit hosts;
12994 they were never used, so remove them instead of repairing them.
12995 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
12996 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
12997 Previously, this ceilinged at INT_MAX, but that doesn't work on
12999 (allocate_pseudovector): Don't use EMACS_INT when int would do.
13001 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
13002 (allocate_vectorlike): Check for ptrdiff_t overflow.
13003 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13004 when a (possibly-narrower) signed value would do just as well.
13005 We prefer using signed arithmetic, to avoid comparison confusion.
13007 * alloc.c: Catch some string size overflows that we were missing.
13008 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
13009 for convenience in STRING_BYTES_MAX.
13010 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
13011 The definition here is exact; the one in lisp.h was approximate.
13012 (allocate_string_data): Check for string overflow. This catches
13013 some instances we weren't catching before. Also, it catches
13014 size_t overflow on (unusual) hosts where SIZE_MAX <= min

13458 * buffer.h (struct buffer.modtime): Now time_t, not int.
13459 * fileio.c (Fvisited_file_modtime): No need for time_t cast now.
13460 * undo.c (Fprimitive_undo): Use time_t, not int, for time_t value.
13462 Minor fixes for signed vs unsigned integers.
13463 * character.h (MAYBE_UNIFY_CHAR):
13464 * charset.c (maybe_unify_char):
13465 * keyboard.c (read_char, reorder_modifiers):
13466 XINT -> XFASTINT, since the integer must be nonnegative.
13467 * ftfont.c (ftfont_spec_pattern):
13468 * keymap.c (access_keymap, silly_event_symbol_error):
13469 XUINT -> XFASTINT, since the integer must be nonnegative.
13470 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
13471 since it makes no difference and we prefer signed.
13472 * keyboard.c (record_char): Use XUINT when all the neighbors do.
13473 (access_keymap): NATNUMP -> INTEGERP, since the integer must be

13520 code. Minor doc-string fixes.
13522 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
13524 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
13525 Do not assume that spare memory exists; that assumption is valid
13526 only if SYSTEM_MALLOC.
13527 (LARGE_REQUEST): New macro, so that the issue of large requests
13528 is separated from the issue of spare memory.
13530 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
13532 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

13557 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
13558 New error handlers.
13559 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
13560 Obey Vx_select_enable_clipboard_manager. Catch errors in
13561 x_clipboard_manager_save (Bug#8779).
13562 (Vx_select_enable_clipboard_manager): New variable.
13563 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
13565 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
13567 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
13569 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13571 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
13572 in the current matrix if keep_current_p is non-zero.

13578 2011-06-03 Eli Zaretskii <eliz@gnu.org>
13580 Support bidi reordering of text covered by display properties.
13582 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
13583 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
13584 (bidi_cache_search, bidi_cache_iterator_state)
13585 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
13586 (bidi_level_of_next_char, bidi_move_to_visually_next):
13587 Support character positions inside a run of characters covered by a
13589 (bidi_paragraph_init, bidi_resolve_explicit_1)
13590 (bidi_level_of_next_char): Call bidi_fetch_char and
13591 bidi_fetch_char_advance instead of FETCH_CHAR and

13594 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
13596 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
13597 instead of using explicit *_CHAR codes.
13598 (bidi_resolve_explicit, bidi_resolve_weak):
13599 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
13600 bidirectional text is supported only in multibyte buffers.
13601 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
13602 it to initialize the frame_window_p member of struct bidi_it.
13603 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
13604 (bidi_resolve_explicit, bidi_resolve_weak)

13606 bidi_it->nchars is non-positive.
13607 (bidi_level_of_next_char): Don't try to lookup the cache for the
13608 next/previous character if nothing is cached there yet, or if we
13609 were just reseat()'ed to a new position.
13611 * xdisp.c (set_cursor_from_row): Set start and stop points
13612 according to the row's direction when priming the loop that looks
13613 for the glyph on which to display cursor.
13614 (single_display_spec_intangible_p): Function deleted.
13615 (display_prop_intangible_p): Reimplement to call
13616 handle_display_spec instead of single_display_spec_intangible_p.
13617 Accept 3 additional arguments needed by handle_display_spec.
13618 This fixes incorrect cursor motion across display property with complex
13619 values: lists, `(when COND...)' forms, etc.
13620 (single_display_spec_string_p): Support property values that are
13621 lists with the argument STRING its top-level element.
13622 (display_prop_string_p): Fix the condition for processing a
13623 property that is a list to be consistent with handle_display_spec.
13624 (handle_display_spec): New function, refactored from the
13625 last portion of handle_display_prop.
13626 (compute_display_string_pos): Accept additional argument
13627 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
13628 value of a `display' property is a "replacing spec".
13629 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
13630 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
13631 the display property, but just return a value indicating whether
13632 the display property will replace the characters it covers.
13633 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
13634 frame_window_p members of struct bidi_it.
13635 (compute_display_string_pos, compute_display_string_end):
13637 (push_it): Accept second argument POSITION, where pop_it should
13638 jump to continue iteration.
13639 (reseat_1): Initialize bidi_it.disp_pos.
13641 * keyboard.c (adjust_point_for_property): Adjust the call to
13642 display_prop_intangible_p to its new signature.
13644 * dispextern.h (struct bidi_it): New member frame_window_p.
13645 (bidi_init_it): Update prototypes.
13646 (display_prop_intangible_p): Update prototype.
13647 (compute_display_string_pos, compute_display_string_end):
13648 Declare prototypes.
13649 (struct bidi_it): New members nchars and disp_pos. ch_len is now
13652 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
13654 Malloc failure behavior now depends on size of allocation.
13655 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
13656 * lisp.h: Change signatures accordingly.
13657 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
13658 All callers changed. (Bug#8762)
13660 * gnutls.c: Use Emacs's memory allocators.
13661 Without this change, the gnutls library would invoke malloc etc.
13662 directly, which causes problems on non-SYNC_INPUT hosts, and which
13663 runs afoul of improving memory_full behavior. (Bug#8761)
13664 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
13665 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
13666 xfree instead of the default malloc, realloc, free.
13667 (Fgnutls_boot): No need to check for memory allocation failure,
13668 since xmalloc does that for us.
13670 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
13671 * category.c (hash_get_category_set):
13672 * ccl.c (ccl_driver):

13685 (Fsxhash, Fgethash, Fputhash, Fmaphash):
13686 * image.c (make_image, search_image_cache, lookup_image)
13687 (xpm_put_color_table_h):
13688 * lisp.h (struct Lisp_Hash_Table):
13689 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
13690 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
13691 for hashes and hash indexes, instead of 'unsigned' and 'int'.
13692 * alloc.c (allocate_vectorlike):
13693 Check for overflow in vector size calculations.
13694 * ccl.c (ccl_driver):
13695 Check for overflow when converting EMACS_INT to int.
13696 * fns.c, image.c: Remove unnecessary static decls that would otherwise
13697 need to be updated by these changes.
13698 * fns.c (make_hash_table, maybe_resize_hash_table):
13699 Check for integer overflow with large hash tables.
13700 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
13701 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
13702 (SXHASH_REDUCE): New macro.
13703 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
13704 Use it instead of discarding useful hash info with large hash values.
13705 (sxhash_float): New function.
13706 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
13707 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
13708 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
13709 Rewrite to use FIXNUM_BITS, as this simplifies things.
13710 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
13711 Adjust signatures to match updated version of code.
13712 (consing_since_gc): Now EMACS_INT, since a single hash table can
13713 use more than INT_MAX bytes.
13715 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
13717 Make it possible to build with GCC-4.6+ -O2 -flto.
13719 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
13721 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
13723 * minibuf.c (get_minibuffer, read_minibuf_unwind):
13724 Call minibuffer-inactive-mode.
13726 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
13728 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
13729 Update dependencies.
13731 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
13733 * data.c (init_data): Remove code for UTS, this system is not
13736 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
13738 Don't force ./temacs to start in terminal mode.
13740 * frame.c (make_initial_frame): Initialize faces in all cases, not
13741 only when CANNOT_DUMP is defined.
13742 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
13744 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
13746 * dispnew.c (add_window_display_history): Use const for the string
13747 pointer. Remove declaration, not needed.
13749 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
13751 Use 'inline', not 'INLINE'.
13752 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
13753 * alloc.c, fontset.c (INLINE): Remove.
13754 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
13755 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
13756 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
13757 * gmalloc.c (register_heapinfo): Use inline unconditionally.
13758 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
13760 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
13762 Make it possible to run ./temacs.
13764 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
13765 syms_of_callproc does the same thing. Remove test for
13766 "initialized", do it in the caller.
13767 * emacs.c (main): Avoid calling set_initial_environment when dumping.
13769 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
13771 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
13772 (read_minibuf): Use get_minibuffer.
13773 (syms_of_minibuf): Use DEFSYM.
13774 (Qmetadata): New var.
13775 * data.c (Qbuffer): Don't make it static.
13776 (syms_of_data): Use DEFSYM.
13778 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
13780 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
13781 (CCL_CODE_MIN): New macro.
13783 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
13785 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
13787 * eval.c (Qdebug): Now static.
13788 * lisp.h (Qdebug): Remove decl. This reverts a part of the
13789 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
13790 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
13792 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
13794 * image.c: Various fixes to ImageMagick code comments.
13795 (Fimagemagick_types): Doc fix.
13797 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
13799 Minor fixes prompted by GCC 4.6.0 warnings.
13801 * xselect.c (converted_selections, conversion_fail_tag): Now static.
13803 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
13804 (x_clipboard_manager_save_all): Move extern decl to ...
13805 * xterm.h: ... here, so that it can be checked for consistency.
13807 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
13809 * xselect.c (x_clipboard_manager_save_frame)
13810 (x_clipboard_manager_save_all): New functions.
13811 (Fx_clipboard_manager_save): Lisp function deleted.
13813 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
13814 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
13816 * xterm.h: Update prototype.
13818 2011-05-28 William Xu <william.xwl@gmail.com>
13820 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
13821 exiting (Bug#8239).
13823 2011-05-28 Jim Meyering <meyering@redhat.com>
13825 Avoid a sign-extension bug in crypto_hash_function.
13826 * fns.c (to_uchar): Define.
13827 (crypto_hash_function): Use it to convert some newly-signed
13828 variables to unsigned, to avoid sign-extension bugs. For example,
13829 without this change, (md5 "truc") would evaluate to
13830 45723a2aff78ff4fff7fff1114760e62 rather than the expected
13831 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
13832 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
13834 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13836 Integer overflow fixes.
13838 * dbusbind.c: Serial number integer overflow fixes.
13839 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
13840 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
13841 to hold a serial number that is too large for a fixnum.
13842 (Fdbus_method_return_internal, Fdbus_method_error_internal):
13843 Check for serial numbers out of range. Decode any serial number
13844 that was so large that it became a float. (Bug#8722)
13846 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
13847 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13848 Use XFASTINT rather than XUINT when numbers are nonnegative.
13849 (xd_append_arg, Fdbus_method_return_internal):
13850 (Fdbus_method_error_internal): Likewise. Also, for unsigned
13851 arguments, check that Lisp number is nonnegative, rather than
13852 silently wrapping negative numbers around. (Bug#8722)
13853 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
13856 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
13858 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
13860 ccl: Add integer overflow checks.
13861 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
13862 (IN_INT_RANGE): New macros.
13863 (ccl_driver): Use them to check for integer overflow when
13864 decoding a CCL program. Many of the new checks are whether XINT (x)
13865 fits in int; it doesn't always, on 64-bit hosts. The new version
13866 doesn't catch all possible integer overflows, but it's an
13867 improvement. (Bug#8719)
13869 * alloc.c (make_event_array): Use XINT, not XUINT.
13870 There's no need for unsigned here.
13872 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
13873 This follows up to the 2011-05-06 change that substituted uintptr_t
13874 for EMACS_INT. This case wasn't caught back then.
13876 Rework Fformat to avoid integer overflow issues.
13877 * editfns.c: Include <float.h> unconditionally, as it's everywhere
13878 now (part of C89). Include <verify.h>.
13879 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
13880 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
13881 (Fformat): Avoid the prepass trying to compute sizes; it was only
13882 approximate and thus did not catch overflow reliably. Instead, walk
13883 through the format just once, formatting and computing sizes as we go,
13884 checking for integer overflow at every step, and allocating a larger
13885 buffer as needed. Keep track separately whether the format is
13886 multibyte. Keep only the most-recently calculated precision, rather
13887 than them all. Record whether each argument has been converted to
13888 string. Use EMACS_INT, not int, for byte and char and arg counts.
13889 Support field widths and precisions larger than INT_MAX. Avoid
13890 sprintf's undefined behavior with conversion specifications such as %#d
13891 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
13892 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
13893 formatting out-of-range floating point numbers with int
13894 formats. (Bug#8668)
13896 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
13898 * data.c: Avoid integer truncation in expressions involving floats.
13899 * data.c: Include <intprops.h>.
13900 (arith_driver): When there's an integer overflow in an expression
13901 involving floating point, convert the integers to floating point
13902 so that the resulting value does not suffer from catastrophic
13903 integer truncation. For example, on a 64-bit host (* 4
13904 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
13905 Do not rely on undefined behavior after integer overflow.
13907 merge count_size_as_multibyte, parse_str_to_multibyte
13908 * character.c, character.h (count_size_as_multibyte):
13909 Rename from parse_str_to_multibyte; all uses changed.
13910 Check for integer overflow.
13911 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
13912 since it's now a duplicate of the other. This is more of
13913 a character than a buffer op, so better that it's in character.c.
13914 * fns.c, print.c: Adjust to above changes.
13916 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
13918 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
13920 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13922 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13923 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
13924 (x_clipboard_manager_save): Now static.
13925 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
13927 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13928 (crypto_hash_function): Now static.
13929 Fix pointer signedness problems. Avoid unnecessary initializations.
13931 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
13933 * termhooks.h (Vselection_alist): Make it terminal-local.
13935 * terminal.c (create_terminal): Initialize it.
13937 * xselect.c: Support for clipboard managers.
13938 (Vselection_alist): Move to termhooks.h as terminal-local var.
13939 (LOCAL_SELECTION): New macro.
13940 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
13941 (symbol_to_x_atom): Remove gratuitous arg.
13942 (x_handle_selection_request, lisp_data_to_selection_data)
13943 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
13944 (x_own_selection, x_get_local_selection, x_convert_selection):
13945 New arg, specifying work frame. Use terminal-local Vselection_alist.
13946 (some_frame_on_display): Delete unused function.
13947 (Fx_own_selection_internal, Fx_get_selection_internal)
13948 (Fx_disown_selection_internal, Fx_selection_owner_p)
13949 (Fx_selection_exists_p): New optional frame arg.
13950 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
13951 (x_handle_selection_clear): Don't treat other terminals with the
13952 same keyboard specially. Use the terminal-local Vselection_alist.
13953 (x_clear_frame_selections): Use Frun_hook_with_args.
13955 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
13957 * xterm.h: Add support for those atoms.
13959 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
13961 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
13962 (converted_selections, conversion_fail_tag): New global variables.
13963 (x_selection_request_lisp_error): Free the above.
13964 (x_get_local_selection): Remove unnecessary code.
13965 (x_reply_selection_request): Args changed; handle arbitrary array
13966 of converted selections stored in converted_selections.
13967 Separate the XChangeProperty and SelectionNotify steps.
13968 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
13969 (x_convert_selection): New function.
13970 (x_handle_selection_event): Simplify.
13971 (x_get_foreign_selection): Don't ignore incoming requests while
13972 waiting for an answer; this will fail when we implement
13973 SAVE_TARGETS, and seems unnecessary anyway.
13974 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
13975 (Vx_sent_selection_functions): Doc fix.
13977 2011-05-26 Leo Liu <sdl.web@gmail.com>
13979 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
13981 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13983 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
13985 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
13986 for fringe update if it has periodic bitmap.
13987 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
13988 and fringe_bitmap_periodic_p.
13990 * fringe.c (get_fringe_bitmap_data): New function.
13991 (draw_fringe_bitmap_1, update_window_fringes): Use it.
13992 (update_window_fringes): Record periodicity of fringe bitmap in glyph
13993 row. Mark glyph row for fringe update if periodicity changed.
13995 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
13996 for fringe update unless it has periodic bitmap.
13998 2011-05-25 Kenichi Handa <handa@m17n.org>
14000 * xdisp.c (get_next_display_element): Set correct it->face_id for
14001 a static composition.
14003 2011-05-24 Leo Liu <sdl.web@gmail.com>
14006 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
14008 * fns.c (crypto_hash_function, Fsha1): New function.
14009 (Fmd5): Use crypto_hash_function.
14010 (syms_of_fns): Add Ssha1.
14012 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14014 * gnutls.c: Remove unused macros.
14015 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14016 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14017 Remove macros that are defined and never used.
14018 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14020 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14022 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14023 (Fx_get_selection_internal): Minor cleanup.
14024 (Fx_own_selection_internal): Rename arguments for consistency with
14027 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14029 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
14031 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14033 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
14035 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14037 * dispnew.c (scrolling_window): Don't exclude the case that the
14038 last enabled row in the desired matrix touches the bottom boundary.
14040 2011-05-21 Glenn Morris <rgm@gnu.org>
14042 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
14043 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
14044 and add some more files.
14046 2011-05-20 Eli Zaretskii <eliz@gnu.org>
14048 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
14049 report_file_error introduced by the change from 2011-05-07.
14051 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14053 * systime.h (Time): Define only if emacs is defined.
14054 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14055 where the include path doesn't have X11/X.h by default. See
14056 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14058 2011-05-20 Kenichi Handa <handa@m17n.org>
14060 * composite.c (find_automatic_composition): Fix previous change.
14062 2011-05-20 Glenn Morris <rgm@gnu.org>
14064 * lisp.mk: New file, split from Makefile.in.
14065 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14066 (shortlisp): Remove.
14067 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14069 2011-05-19 Glenn Morris <rgm@gnu.org>
14071 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14072 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14073 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14074 (lisp): Set the order to that of loadup.el.
14075 (shortlisp): Make it a copy of $lisp.
14076 (SOME_MACHINE_LISP): Remove.
14077 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14078 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14080 2011-05-18 Kenichi Handa <handa@m17n.org>
14082 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14083 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14084 (find_automatic_composition): Mostly rewrite for efficiency.
14086 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14088 * makefile.w32-in: Update dependencies.
14090 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14092 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14093 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14095 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14097 Fix some integer overflow issues, such as string length overflow.
14099 * insdel.c (count_size_as_multibyte): Check for string overflow.
14101 * character.c (lisp_string_width): Check for string overflow.
14102 Use EMACS_INT, not int, for string indexes and lengths; in
14103 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14104 the resulting string length overflows an EMACS_INT; instead,
14105 report a string overflow if no precision given. When checking for
14106 precision exhaustion, use a check that cannot possibly have
14107 integer overflow. (Bug#8675)
14108 * character.h (lisp_string_width): Adjust to new signature.
14110 * alloc.c (string_overflow): New function.
14111 (Fmake_string): Use it. This doesn't change behavior, but saves
14112 a few bytes and will simplify future changes.
14113 * character.c (string_escape_byte8): Likewise.
14114 * lisp.h (string_overflow): New decl.
14116 Fixups, following up to the user-interface timestamp change.
14117 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14118 for UI timestamps, instead of unsigned long.
14119 * msdos.c (mouse_get_pos): Likewise.
14120 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14121 * w32gui.h (Time): Define by including "systime.h" rather than by
14122 declaring it ourselves. (Bug#8664)
14124 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14125 * image.c (clear_image_cache): Likewise.
14127 * term.c (term_mouse_position): Don't assume time_t wraparound.
14129 Be more systematic about user-interface timestamps.
14130 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14131 and sometimes 'EMACS_UINT', to represent these timestamps.
14132 This change causes it to use 'Time' uniformly, as that's what X uses.
14133 This makes the code easier to follow, and makes it easier to catch
14134 integer overflow bugs such as Bug#8664.
14135 * frame.c (Fmouse_position, Fmouse_pixel_position):
14136 Use Time, not unsigned long, for user-interface timestamps.
14137 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14138 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14139 * keyboard.h (last_event_timestamp): Likewise.
14140 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14141 * menu.h (xmenu_show): Likewise.
14142 * term.c (term_mouse_position): Likewise.
14143 * termhooks.h (struct input_event.timestamp): Likewise.
14144 (struct terminal.mouse_position_hook): Likewise.
14145 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14146 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14147 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14148 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14149 what it was before.
14150 * menu.h, termhooks.h: Include "systime.h", for Time.
14152 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14153 Don't assume that the difference between two unsigned long values
14154 can fit into an integer. At this point, we know button_down_time
14155 <= event->timestamp, so the difference must be nonnegative, so
14156 there's no need to cast the result if double-click-time is
14157 nonnegative, as it should be; check that it's nonnegative, just in
14158 case. This bug is triggered when events are more than 2**31 ms
14159 apart (about 25 days). (Bug#8664)
14161 * xselect.c (last_event_timestamp): Remove duplicate decl.
14162 (x_own_selection): Remove needless cast to unsigned long.
14164 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14165 that always fit in int. Use a sentinel instead of a counter, to
14166 avoid a temp and to allay GCC's concerns about possible int overflow.
14167 * frame.h (struct frame): Use int for menu_bar_items_used
14168 instead of EMACS_INT, since it always fits in int.
14170 * menu.c (grow_menu_items): Check for int overflow.
14172 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14174 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14175 Before, the code was not consistent. These values cannot exceed
14176 2**31 - 1 so there's no need to make them unsigned.
14177 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14178 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14179 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14181 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14183 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14184 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14185 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14186 presumably because the widths might not match.
14188 * window.c (size_window): Avoid needless test at loop start.
14190 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14192 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14194 2011-05-12 Drew Adams <drew.adams@oracle.com>
14196 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14198 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14200 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14201 `width' to `bar_area_x' and `bar_area_width', respectively.
14202 (x_scroll_run): Take account of fringe background extension.
14204 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14205 Rename local vars `left' and `width' to `bar_area_x' and
14206 `bar_area_width', respectively.
14207 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14208 background extension.
14210 2011-05-10 Jim Meyering <meyering@redhat.com>
14212 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14214 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14216 * image.c (Finit_image_library): Return t for built-in image types,
14217 like pbm and xbm. (Bug#8640)
14219 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14221 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14223 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14225 * w32console.c (Fset_screen_color): Doc fix.
14226 (Fget_screen_color): New function.
14227 (syms_of_ntterm): Defsubr it.
14229 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14230 unlink the temporary file if Fcall_process didn't create it in the
14232 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14233 child process will be redirected to a file specified with `:file'.
14234 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14235 cue to call_process_cleanup not to close that handle.
14237 2011-05-07 Ben Key <bkey76@gmail.com>
14239 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14240 one of two shell specific rules, either bootstrap-temacs-CMD or
14241 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14242 to the previous implementation of the bootstrap-temacs rule.
14243 The bootstrap-temacs-CMD rule is similar to the previous
14244 implementation of the bootstrap-temacs rule except that it
14245 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14248 These changes, along with some changes to nt/configure.bat,
14249 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14250 earlier fix to add support for --cflags and --ldflags options
14251 that include quotes so that it works whether make uses cmd or
14254 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14256 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14257 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14259 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14260 a string. Handle both cases.
14261 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14262 (Fdbus_register_method): Use Qinvalid_function.
14264 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14266 * makefile.w32-in: Update dependencies.
14267 (LISP_H): Add inttypes.h and stdin.h.
14268 (PROCESS_H): Add unistd.h.
14270 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14272 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14273 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14275 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14277 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14279 * term.c (vfatal): Remove stray call to va_end.
14280 It's not needed and the C Standard doesn't allow it here anyway.
14282 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14283 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14285 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14288 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14290 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14292 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14294 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14296 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14298 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14299 * charset.c (Fdefine_charset_internal): Don't initialize
14300 charset.code_space[15]. The value was garbage, on hosts with
14301 32-bit int (Bug#8600).
14303 * lread.c (read_integer): Be more consistent with string-to-number.
14304 Use string_to_number to do the actual conversion; this avoids
14305 rounding errors and fixes some other screwups. Without this fix,
14306 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14307 (digit_to_number): Move earlier, for benefit of read_integer.
14308 Return -1 if the digit is out of range for the base, -2 if it is
14309 not a digit in any supported base. (Bug#8602)
14311 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14313 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14314 to match comment at start of function. This also removes a
14315 GCC warning about overflow in a 32+64-bit port.
14317 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14319 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14320 Reported by Stefan Monnier in
14321 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14322 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14323 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14325 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14326 (EMACS_UINTPTR): Likewise, with uintptr_t.
14328 * lisp.h: Prefer 64-bit EMACS_INT if available.
14329 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14330 on 32-bit hosts that have 64-bit int, so that they can access
14332 However, temporarily disable this change unless the temporary
14333 symbol WIDE_EMACS_INT is defined.
14335 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14337 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14338 This removes an assumption that EMACS_INT and long are the same
14339 width as pointers. The assumption is true for Emacs porting targets
14340 now, but we want to make other targets possible.
14341 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14342 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14343 In the rest of the code, change types of integers that hold casted
14344 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14345 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14346 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14347 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14348 No need to cast type when ORing.
14349 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14350 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14351 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14352 assume EMACS_INT is the same width as char *.
14353 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14354 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14355 Remove no-longer-needed casts.
14356 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14357 (xg_tool_bar_help_callback, xg_make_tool_item):
14358 Use EMACS_INTPTR to hold an integer
14359 that will be cast to void *; this can avoid a GCC warning
14360 if EMACS_INT is not the same width as void *.
14361 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14362 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14363 (current_message_1, set_message_1):
14364 Use a local to convert to proper width without a cast.
14365 * xmenu.c (dialog_selection_callback): Likewise.
14367 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14368 Also, don't assume VALBITS / RAND_BITS is less than 5,
14369 and don't rely on undefined behavior when shifting a 1 left into
14371 * lisp.h (get_random): Change signature to match.
14373 * lread.c (hash_string): Use size_t, not int, for hash computation.
14374 Normally we prefer signed values; but hashing is special, because
14375 it's better to use unsigned division on hash table sizes so that
14376 the remainder is nonnegative. Also, size_t is the natural width
14377 for hashing into memory. The previous code used 'int', which doesn't
14378 retain enough info to hash well into very large tables.
14379 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14381 * dbusbind.c: Don't possibly lose pointer info when converting.
14382 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14383 Use XPNTR rather than XHASH, so that the high-order bits of
14384 the pointer aren't lost when converting through void *.
14386 * eval.c (Fautoload): Don't double-shift a pointer.
14388 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14390 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14392 * gnutls.c (DEF_GNUTLS_FN):
14393 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14395 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14397 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14400 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14402 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14403 New version that can reserve upto 2GB of heap space.
14405 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14407 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14409 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14411 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14412 `gnutls_certificate_set_x509_key_file'.
14414 2011-05-05 Juanma Barranquero <lekktu@gmail.com>

14417 Update dependencies.
14419 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14421 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14422 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14423 Remove unused parameter `fildes'.
14424 * process.c (read_process_output, send_process): Don't pass it.
14426 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14428 Fix previous change: the library cache is defined in w32.c.
14429 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14430 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14432 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14434 Implement dynamic loading of GnuTLS on Windows.
14436 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14437 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14438 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14441 * gnutls.c (Qgnutls_dll): Define.

14450 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14451 (Fgnutls_available_p): New function.
14452 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

14460 (w32_delayed_load): Move to w32.c.
14462 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
14464 * w32.c (QCloaded_from, Vlibrary_cache): Define.
14465 (w32_delayed_load): Move from image.c. When loading a library, record
14466 its filename in the :loaded-from property of the library id.
14467 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
14468 Initialize and staticpro them.
14469 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
14471 * process.c: Include lisp.h before w32.h, not after.
14472 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
14473 instead of gnutls_record_check_pending.
14475 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
14477 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
14479 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
14480 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
14483 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
14485 * xterm.c (x_set_frame_alpha): Do not set property on anything
14486 else than FRAME_X_OUTER_WINDOW (Bug#8608).
14488 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14490 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
14492 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14494 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
14495 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

14508 * sysdep.c (wait_for_termination_1): Make static.
14509 (wait_for_termination, interruptible_wait_for_termination):
14510 Move after wait_for_termination_1.
14512 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
14514 * sysdep.c (interruptible_wait_for_termination): New function
14515 which is like wait_for_termination, but allows keyboard
14518 * callproc.c (Fcall_process): Add (:file "file") as an option for
14520 (Fcall_process_region): Ditto.
14522 2011-04-30 Eli Zaretskii <eliz@gnu.org>
14524 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
14525 rather than `XVECTOR (FOO)->size'.
14527 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
14528 inttypes.h, as a gnulib replacement is used if it not available in
14531 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14533 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
14534 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
14535 of MOST_POSITIVE_FIXNUM. (Bug#8528)
14537 * coding.c (coding_alloc_by_realloc): Error out if destination
14538 will grow beyond MOST_POSITIVE_FIXNUM.
14539 (decode_coding_emacs_mule): Abort if there isn't enough place in
14540 charbuf for the composition carryover bytes. Reserve an extra
14541 space for up to 2 characters produced in a loop.
14542 (decode_coding_iso_2022): Abort if there isn't enough place in
14543 charbuf for the composition carryover bytes.
14545 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14547 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
14548 aborting when %lld or %lll format is passed.
14549 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
14550 %llo or %llx format is passed. (Bug#8545)
14552 * window.c (window_scroll_line_based): Use a marker instead of
14553 simple variables to record original value of point. (Bug#7952)
14555 * doprnt.c (doprnt): Fix the case where a multibyte sequence
14556 produced by %s or %c overflows available buffer space. (Bug#8545)
14558 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
14560 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
14561 (SIZE_MAX): Move defn after all includes, as they might #define it.
14563 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14565 * w32.c (init_environment): Warn about defaulting HOME to C:\.
14567 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14569 * keyboard.c (Qdelayed_warnings_hook): Define.
14570 (command_loop_1): Run `delayed-warnings-hook'
14571 if Vdelayed_warnings_list is non-nil.
14572 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
14573 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
14575 2011-04-28 Eli Zaretskii <eliz@gnu.org>
14577 * doprnt.c (doprnt): Don't return value smaller than the buffer
14578 size if the message was truncated. (Bug#8545).
14580 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14582 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
14583 (Fx_window_property): #if-0 the whole functions, not just the bodies.
14585 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14587 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
14589 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
14591 * makefile.w32-in: Update dependencies.
14593 2011-04-27 Eli Zaretskii <eliz@gnu.org>
14595 Improve `doprnt' and its usage. (Bug#8545)
14596 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
14597 `format_end'. Remove support for %l as a conversion specifier.
14598 Don't use xrealloc. Improve diagnostics when the %l size modifier
14599 is used. Update the commentary.
14601 * eval.c (verror): Simplify calculation of size_t.
14603 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
14606 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
14608 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
14611 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14613 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
14614 This makes this file independent of the recent pseudovector change.
14616 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
14618 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
14620 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
14621 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
14622 Remove unused local.
14623 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
14625 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
14626 GCC 4.6.0 optimizes based on type-based alias analysis.
14627 For example, if b is of type struct buffer * and v of type struct
14628 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
14629 != &v->size, and therefore "v->size = 1; b->size = 2; return
14630 v->size;" must therefore return 1. This assumption is incorrect
14631 for Emacs, since it type-puns struct Lisp_Vector * with many other
14632 types. To fix this problem, this patch adds a new type struct
14633 vectorlike_header that documents the constraints on layout of vectors
14634 and pseudovectors, and helps optimizing compilers not get fooled
14635 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
14636 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
14637 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
14639 (XSETPVECTYPE): Rewrite in terms of new macro.
14640 (XSETPVECTYPESIZE): New macro, specifying both type and size.
14641 This is a bit clearer, and further avoids the possibility of
14642 undesirable aliasing.
14643 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
14644 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
14645 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
14646 since Lisp_Subr is a special case (no "next" field).
14647 (ASIZE): Now uses header.size rather than size.
14648 All previous uses of XVECTOR (foo)->size replaced to use this macro,
14649 to avoid the hassle of writing XVECTOR (foo)->header.size.
14650 (struct vectorlike_header): New type.
14651 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
14652 object, to help avoid aliasing.
14653 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
14654 (SUBRP): Likewise, since Lisp_Subr is a special case.
14655 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
14656 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
14657 (struct Lisp_Hash_Table): Combine first two members into a single
14658 struct vectorlike_header member. All uses of "size" and "next" members
14659 changed to be "header.size" and "header.next".
14660 * buffer.h (struct buffer): Likewise.
14661 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
14662 * frame.h (struct frame): Likewise.
14663 * process.h (struct Lisp_Process): Likewise.
14664 * termhooks.h (struct terminal): Likewise.
14665 * window.c (struct save_window_data, struct saved_window): Likewise.
14666 * window.h (struct window): Likewise.
14667 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
14668 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
14669 * buffer.c (init_buffer_once): Likewise.
14670 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
14672 * process.c (Fformat_network_address): Use local var for size,
14675 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
14677 Make the Lisp reader and string-to-float more consistent (Bug#8525)
14678 * data.c (atof): Remove decl; no longer used or needed.
14679 (digit_to_number): Move to lread.c.
14680 (Fstring_to_number): Use new string_to_number function, to be
14681 consistent with how the Lisp reader treats infinities and NaNs.
14682 Do not assume that floating-point numbers represent EMACS_INT
14683 without losing information; this is not true on most 64-bit hosts.
14684 Avoid double-rounding errors, by insisting on integers when
14685 parsing non-base-10 numbers, as the documentation specifies.
14686 * lisp.h (string_to_number): New decl, replacing ...
14687 (isfloat_string): Remove.
14688 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
14689 (read1): Do not accept +. and -. as integers; this
14690 appears to have been a coding error. Similarly, do not accept
14691 strings like +-1e0 as floating point numbers. Do not report
14692 overflow for integer overflows unless the base is not 10 which
14693 means we have no simple and reliable way to continue.
14694 Break out the floating-point parsing into a new
14695 function string_to_number, so that Fstring_to_number parses
14696 floating point numbers consistently with the Lisp reader.
14697 (digit_to_number): Move here from data.c. Make it static inline.
14698 (E_CHAR, EXP_INT): Remove, replacing with ...
14699 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
14700 (string_to_number): New function, replacing isfloat_string.
14701 This function checks for valid syntax and produces the resulting
14702 Lisp float number too. Rework it so that string-to-number
14703 no longer mishandles examples like "1.0e+". Use strtoumax,
14704 so that overflow for non-base-10 numbers is reported only when
14705 there's no portable and simple way to convert to floating point.
14707 * textprop.c (set_text_properties_1): Rewrite for clarity,
14708 and to avoid GCC warning about integer overflow.
14710 * intervals.h (struct interval): Use EMACS_INT for members
14711 where EMACS_UINT might cause problems. See
14712 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
14713 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
14714 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
14716 (offset_intervals): Tell GCC not to worry about length overflow
14717 when negating a negative length.
14719 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
14720 (overrun_check_free): Likewise.
14722 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
14723 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
14726 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14727 (gnutls_make_error): Rename local to avoid shadowing.
14728 (gnutls_emacs_global_deinit): ifdef out; not used.
14729 (Fgnutls_boot): Use const for pointer to readonly storage.
14730 Comment out unused local. Fix pointer signedness problems.
14732 * lread.c (openp): Don't stuff size_t into an 'int'.
14733 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
14734 about possible signed overflow.
14736 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14737 (GDK_KEY_g): Don't define if already defined.
14738 (xg_prepare_tooltip): Avoid pointer signedness problem.
14739 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
14741 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
14742 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
14744 * xfns.c (Fx_window_property): Simplify a bit,
14745 to make a bit faster and to avoid GCC 4.6.0 warning.
14746 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
14748 * fns.c (internal_equal): Don't assume size_t fits in int.
14750 * alloc.c (compact_small_strings): Tighten assertion a little.
14752 Replace pEd with more-general pI, and fix some printf arg casts.
14753 * lisp.h (pI): New macro, generalizing old pEd macro to other
14754 conversion specifiers. For example, use "...%"pI"d..." rather
14755 than "...%"pEd"...".
14756 (pEd): Remove. All uses replaced with similar uses of pI.
14757 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
14758 * alloc.c (check_pure_size): Don't overflow by converting size to int.
14759 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
14760 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
14761 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
14762 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
14763 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
14765 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
14766 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
14767 * print.c (safe_debug_print, print_object): Likewise.
14768 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
14770 Use pI instead of if-then-else-abort. Use %p to avoid casts,
14771 avoiding the 0 flag, which is not portable.
14772 * process.c (Fmake_network_process): Use pI to avoid cast.
14773 * region-cache.c (pp_cache): Likewise.
14774 * xdisp.c (decode_mode_spec): Likewise.
14775 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
14776 behavior on 64-bit hosts with printf arg.
14777 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
14778 (x_stop_queuing_selection_requests): Likewise.
14779 (x_get_window_property): Don't truncate byte count to an 'int'
14782 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
14783 here, since it parses constructs like leading '-' and spaces,
14784 which are not wanted; and it overflows with large numbers.
14785 Instead, simply match F[0-9]+, which is what is wanted anyway.
14787 * alloc.c: Remove unportable assumptions about struct layout.
14788 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
14789 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
14790 (allocate_vectorlike, make_pure_vector): Use the new macros,
14791 plus offsetof, to remove unportable assumptions about struct layout.
14792 These assumptions hold on all porting targets that I know of, but
14793 they are not guaranteed, they're easy to remove, and removing them
14794 makes further changes easier.
14796 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
14797 This doesn't fix a bug but makes the code clearer.
14798 (string_overrun_cookie): Now const. Use initializers that
14799 don't formally overflow signed char, to avoid warnings.
14800 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
14801 can cause Emacs to crash when string overrun checking is enabled.
14802 (allocate_buffer): Don't assume sizeof (struct buffer) is a
14803 multiple of sizeof (EMACS_INT); it need not be, if
14804 alignof(EMACS_INT) < sizeof (EMACS_INT).
14805 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
14807 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

14836 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
14837 "cast to pointer from integer of different size".
14839 Improve doprnt and its use in verror. (Bug#8545)
14840 * doprnt.c (doprnt): Document the set of format control sequences
14841 supported by the function. Use SAFE_ALLOCA instead of always
14844 * eval.c (verror): Don't limit the buffer size at size_max-1, that
14845 is one byte too soon. Don't use xrealloc; instead xfree and
14848 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
14850 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

14856 parameters of `gnutls-boot' and documented those parameters in the
14857 docstring. Start callback support.
14858 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
14859 unless a fatal error occurred. Call gnutls_alert_send_appropriate

14957 * callint.c (Fcall_interactively): When displaying error message
14958 about invalid control letter, pass the character's codepoint, not

14963 codepoint of an invalid character, to avoid displaying a bogus
14966 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
14967 `error', not SYMBOL_NAME itself.
14969 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

14972 * charset.c (check_iso_charset_parameter): Fix incorrect argument
14973 to `error' in error message about FINAL_CHAR argument. Make sure
14974 FINAL_CHAR is a character, and use %c when it is passed as
14975 argument to `error'.
14977 2011-04-23 Eli Zaretskii <eliz@gnu.org>
14979 * s/ms-w32.h (localtime): Redirect to sys_localtime.
14981 * w32.c: Include <time.h>.

15041 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
15042 by pacifying GCC about it. Maybe it's time to retire it?
15043 * xfaces.c (USG, __TIMEVAL__): Likewise.
15045 * dispextern.h (struct redisplay_interface): Rename param
15046 to avoid shadowing.
15047 * termhooks.h (struct terminal): Likewise.
15048 * xterm.c (xembed_send_message): Likewise.
15050 * insdel.c (make_gap_smaller): Define only if
15051 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.

15164 * nsfont.m: Fixed bugs in ns_get_family and
15165 ns_descriptor_to_entity that were caused by using free to
15166 deallocate memory blocks that were allocated by xmalloc (via
15167 xstrdup). This caused Emacs to crash when compiled with
15168 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
15169 --enable-checking=xmallocoverrun). xfree is now used to
15170 deallocate these memory blocks.
15172 2011-04-15 Paul Eggert <eggert@cs.ucla.edu>
15174 * sysdep.c (emacs_read): Remove unnecessary check vs MAX_RW_COUNT.

15184 (emacs_read, emacs_write): Remove check for negative size, as the
15185 Emacs source code has been audited now.
15186 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
15187 (emacs_read, emacs_write): Use it.
15188 * process.c (send_process): Adjust to the new signatures of
15189 emacs_write and emacs_gnutls_write. Do not attempt to store
15190 a byte offset into an 'int'; it might overflow.
15191 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

15215 * font.c (Qopentype): Don't make static (used from w32uniscribe.c).
15217 2011-04-14 Paul Eggert <eggert@cs.ucla.edu>

15623 * syntax.c (Fsyntax_table_p): New forward static decl.
15624 (skip_chars): Remove duplicate decl.

15638 2011-04-13 Eli Zaretskii <eliz@gnu.org>
15640 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
15641 when at ZV. (Bug#8487)
15643 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
15645 * charset.c (Fclear_charset_maps): Use xfree instead of free.
15647 * keyboard.c (parse_tool_bar_item): Likewise.
15648 * sound.c (sound_cleanup, alsa_close): Likewise.
15649 * termcap.c (tgetent): Likewise.
15650 * xfns.c (x_default_font_parameter): Likewise.
15651 * xsettings.c (read_and_apply_settings): Likewise.
15653 * alloc.c (overrun_check_malloc, overrun_check_realloc)
15654 (overrun_check_free): Protoize.
15656 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
15658 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
15659 since callers should never pass a negative size.
15660 Change the signature to match that of plain 'read' and 'write'; see
15661 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
15662 * lisp.h: Update prototypes of emacs_write and emacs_read.
15664 2011-04-11 Eli Zaretskii <eliz@gnu.org>
15666 * xdisp.c (redisplay_window): Don't try to determine the character
15667 position of the scroll margin if the window start point w->startp
15668 is outside the buffer's accessible region. (Bug#8468)
15670 2011-04-10 Eli Zaretskii <eliz@gnu.org>
15672 Fix write-region and its subroutines for buffers > 2GB.
15673 * fileio.c (a_write, e_write): Modify declaration of arguments and
15674 local variables to support buffers larger than 2GB.
15675 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
15677 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
15678 argument, local variables, and return value.
15680 * lisp.h: Update prototypes of emacs_write and emacs_read.
15682 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
15684 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
15686 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
15688 Fix more problems found by GCC 4.6.0's static checks.
15690 * xdisp.c (vmessage): Use a better test for character truncation.
15692 * charset.c (load_charset_map): <, not <=, for optimization,
15693 and to avoid potential problems with integer overflow.
15694 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
15695 * casetab.c (set_identity, shuffle): Likewise.
15696 * editfns.c (Fformat): Likewise.
15697 * syntax.c (skip_chars): Likewise.
15699 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
15700 This also lets GCC 4.6.0 generate slightly better loop code.
15702 * callint.c (Fcall_interactively): <, not <=, for optimization.
15703 (Fcall_interactively): Count the number of arguments produced,
15704 not the number of arguments given. This is simpler and lets GCC
15705 4.6.0 generate slightly better code.
15707 * ftfont.c: Distingish more carefully between FcChar8 and char.
15708 The previous code passed unsigned char * to a functions like
15709 strlen and xstrcasecmp that expect char *, which does not
15710 conform to the C standard.
15711 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
15712 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
15713 char * when the C standard requires it.
15715 * keyboard.c (read_char): Remove unused var.
15717 * eval.c: Port to Windows vsnprintf (Bug#8435).
15718 Include <limits.h>.
15719 (SIZE_MAX): Define if the headers do not.
15720 (verror): Do not give up if vsnprintf returns a negative count.
15721 Instead, grow the buffer. This ports to Windows vsnprintf, which
15722 does not conform to C99. Problem reported by Eli Zaretskii.
15723 Also, simplify the allocation scheme, by avoiding the need for
15724 calling realloc, and removing the ALLOCATED variable.
15726 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
15728 Remove invocations of doprnt, as Emacs now uses vsnprintf.
15729 But keep the doprint source code for now, as we might revamp it
15730 and use it again (Bug#8435).
15731 * lisp.h (doprnt): Remove.
15732 * Makefile.in (base_obj): Remove doprnt.o.
15733 * deps.mk (doprnt.o): Remove.
15735 error: Print 32- and 64-bit integers portably (Bug#8435).
15736 Without this change, on typical 64-bit hosts error ("...%d...", N)
15737 was used to print both 32- and 64-bit integers N, which relied on
15738 undefined behavior.
15739 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
15740 * lisp.h (error, verror): Mark as printf-like functions.
15741 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
15742 Report overflow in size calculations when allocating printf buffer.
15743 Do not truncate output string at its first null byte.
15744 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
15745 Truncate the output at a character boundary, since vsnprintf does not
15747 * charset.c (check_iso_charset_parameter): Convert internal
15748 character to string before calling 'error', since %c now has the
15750 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
15751 overflow when computing char to be passed to 'error'. Do not
15752 pass Lisp_Object to 'error'; pass the integer instead.
15753 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
15754 formatted with plain %d.
15756 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
15758 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
15760 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
15762 * xterm.c (x_catch_errors): Remove duplicate declaration.
15764 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
15766 * xdisp.c, lisp.h (message_nolog): Remove; unused.
15768 2011-04-10 Jim Meyering <meyering@redhat.com>
15770 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
15771 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
15772 return ssize_t not "int", and use size_t as the buffer length.
15773 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
15774 * gnutls.h: Update declarations.
15775 * process.c (read_process_output): Use ssize_t, to match.
15776 (send_process): Likewise.
15778 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15780 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
15782 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15784 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
15785 Use unsigned char, to match FcChar8 type definition.
15787 * xterm.c (handle_one_xevent):
15788 * xmenu.c (create_and_show_popup_menu):
15789 * xselect.c (x_decline_selection_request)
15790 (x_reply_selection_request): Avoid type-punned deref of X events.
15792 2011-04-09 Eli Zaretskii <eliz@gnu.org>
15794 Fix some uses of `int' instead of EMACS_INT.
15795 * search.c (string_match_1, fast_string_match)
15796 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
15797 (scan_buffer, find_next_newline_no_quit)
15798 (find_before_next_newline, search_command, Freplace_match)
15799 (Fmatch_data): Make some `int' variables be EMACS_INT.
15801 * xdisp.c (display_count_lines): 3rd argument and return value now
15802 EMACS_INT. All callers changed.
15803 (pint2hrstr): Last argument is now EMACS_INT.
15805 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
15806 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
15807 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
15808 (decode_coding_utf_16, decode_coding_emacs_mule)
15809 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
15810 (decode_coding_ccl, decode_coding_charset)
15811 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
15812 (decode_coding_iso_2022, decode_coding_emacs_mule)
15813 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
15814 <char_offset, last_offset>: Declare EMACS_INT.
15815 (encode_coding_utf_8, encode_coding_utf_16)
15816 (encode_coding_emacs_mule, encode_invocation_designation)
15817 (encode_designation_at_bol, encode_coding_iso_2022)
15818 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
15819 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
15821 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
15822 (encode_invocation_designation): Last argument P_NCHARS is now
15824 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
15825 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
15827 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
15830 * ccl.c (Fccl_execute_on_string): Declare some variables
15833 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
15835 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
15837 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
15839 * process.c (Fformat_network_address): Doc fix.
15841 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
15843 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
15845 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
15847 * keyboard.c (read_char): Call Lisp function help-form-show,
15848 instead of using internal_with_output_to_temp_buffer.
15849 (Qhelp_form_show): New var.
15850 (syms_of_keyboard): Use DEFSYM macro.
15852 * print.c (internal_with_output_to_temp_buffer): Function deleted.
15854 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
15856 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
15858 * process.c (Flist_processes): Remove to Lisp.
15859 (list_processes_1): Delete.
15861 2011-04-06 Eli Zaretskii <eliz@gnu.org>
15863 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
15865 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
15867 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
15869 Fix more problems found by GCC 4.6.0's static checks.
15871 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
15873 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
15875 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
15877 * xdisp.c (vmessage): Mark as a printf-like function.
15879 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
15881 * sound.c (sound_warning): Don't crash if arg contains a printf format.
15883 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
15884 printf-like functions.
15885 (tiff_load): Add casts to remove these marks before passing them
15886 to system-supplied API.
15888 * eval.c (Fsignal): Remove excess argument to 'fatal'.
15890 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
15891 This avoids several warnings with gcc -Wstrict-overflow.
15892 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
15893 directly, rather than having caller test rule sign. This avoids
15894 some unnecessary tests.
15895 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
15896 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
15897 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
15899 * xfont.c (xfont_text_extents): Remove var that was set but not used.
15900 (xfont_open): Avoid unnecessary tests.
15902 * composite.c (composition_gstring_put_cache): Use unsigned integer.
15904 * composite.h, composite.c (composition_gstring_put_cache):
15905 Use EMACS_INT, not int, for length.

15908 breaking out part of COMPOSITION_DECODE_RULE.
15909 (COMPOSITION_DECODE_RULE): Use it.
15910 * composite.c (get_composition_id): Remove unused local vars,
15911 by using the new macro.
15913 * textprop.c (set_text_properties_1): Change while to do-while,
15914 since the condition is always true at first.
15916 * intervals.c (graft_intervals_into_buffer): Mark var as used.
15917 (interval_deletion_adjustment): Return unsigned value.
15920 * process.c (list_processes_1, create_pty, read_process_output):

15922 (create_pty): Remove unnecessary "volatile"s.
15923 (Fnetwork_interface_info): Avoid possibility of int overflow.

15930 (update_syntax_table): Use unsigned instead of int.
15932 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
15933 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
15934 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
15936 * print.c (print_error_message): Avoid int overflow.
15938 * font.c (font_list_entities): Redo for clarity,
15939 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
15941 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
15942 (font_score): Avoid potential overflow in diff calculation.
15944 * fns.c (substring_both): Remove var that is set but not used.
15945 (sxhash): Redo loop for clarity and to avoid wraparound warning.
15947 * eval.c (funcall_lambda): Rename local to avoid shadowing.
15949 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
15950 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
15951 can always succeed if overflow has undefined behavior.
15953 * search.c (boyer_moore, wordify): Remove vars set but not used.
15954 (wordify): Omit three unnecessary tests.
15956 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
15957 All callers changed. This avoids the need for an unused var.
15959 * casefiddle.c (casify_region): Remove var that is set but not used.
15961 * dired.c (file_name_completion): Remove var that is set but not used.
15963 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
15965 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
15966 (Finsert_file_contents): Remove unnecessary code checking fd.
15968 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
15969 Check for integer overflow on size calculations.
15971 * buffer.c (Fprevious_overlay_change): Remove var that is set
15974 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
15975 Remove vars that are set but not used.
15976 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
15977 (timer_check_2): Mark vars as initialized.
15979 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
15981 * image.c (lookup_image): Remove var that is set but not used.
15982 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
15984 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
15985 that are set but not used.
15987 * xfns.c (make_invisible_cursor): Don't return garbage
15988 if XCreateBitmapFromData fails (Bug#8410).
15990 * xselect.c (x_get_local_selection, x_handle_property_notify):
15991 Remove vars that are set but not used.
15993 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
15994 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

16003 (map_tty_color) [!defined MSDOS]: Likewise.
16005 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16007 * coding.c: Remove vars that are set but not used.
16008 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
16009 All callers changed.
16010 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
16011 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
16012 (decode_coding_charset): Remove vars that are set but not used.
16014 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
16015 that is set but not used.
16017 * print.c (print_object): Remove var that is set but not used.
16019 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16020 The gnulib version avoids calling malloc in the usual case,
16021 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16022 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16023 * filelock.c (current_lock_owner): Likewise.
16024 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16025 * sysdep.c: Include allocator.h, careadlinkat.h.
16026 (emacs_no_realloc_allocator): New static constant.
16027 (emacs_readlink): New function.
16028 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16029 ../lib/careadlinkat.h.
16031 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
16033 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
16034 first non-nil return value).
16036 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
16038 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
16039 if not defined (Bug#8403).
16041 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16043 * xdisp.c (display_count_lines): Remove parameter `start',
16044 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16045 (get_char_face_and_encoding): Remove parameter `multibyte_p',

16048 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
16049 and thereabouts. All callers changed.
16050 (get_per_char_metric): Remove parameter `f', unused since
16051 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
16053 2011-04-02 Jim Meyering <meyering@redhat.com>
16055 do not dereference NULL upon failed strdup
16056 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16057 (ns_get_family): Likewise.
16059 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16061 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16063 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16065 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16068 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16070 Add lexical binding.
16072 * window.c (Ftemp_output_buffer_show): New fun.
16073 (Fsave_window_excursion):
16074 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
16076 * lread.c (lisp_file_lexically_bound_p): New function.

16081 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16083 (syms_of_lread): Declare `lexical-binding'.
16085 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16087 * keyboard.c (eval_dyn): New fun.
16088 (menu_item_eval_property): Use it.
16090 * image.c (parse_image_spec): Use Ffunctionp.
16092 * fns.c (concat, mapcar1): Accept byte-code-functions.
16094 * eval.c (Fsetq): Handle lexical vars.
16095 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16096 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16097 (FletX, Flet): Obey lexical binding.
16098 (Fcommandp): Handle closures.
16099 (Feval): New `lexical' arg.
16100 (eval_sub): New function extracted from Feval. Use it almost
16101 everywhere where Feval was used. Look up vars in lexical env.
16103 (Ffunctionp): Move from subr.el.
16104 (Ffuncall): Handle closures.
16105 (apply_lambda): Remove `eval_flags'.
16106 (funcall_lambda): Handle closures and new byte-code-functions.
16107 (Fspecial_variable_p): New function.
16108 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16109 but without exporting it to Lisp.
16111 * doc.c (Fdocumentation, store_function_docstring):
16112 * data.c (Finteractive_form): Handle closures.
16114 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16117 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16119 (exec_byte_code): New function extracted from Fbyte_code to handle new
16120 calling convention for byte-code-functions. Add new byte-codes.
16122 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
16124 * alloc.c (Fmake_symbol): Init new `declared_special' field.
16126 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16128 * xdisp.c (redisplay_internal): Fix prototype.
16130 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16132 * xdisp.c (SCROLL_LIMIT): New macro.
16133 (try_scrolling): Use it when setting scroll_limit.
16134 Limit scrolling to 100 screen lines.
16135 (redisplay_window): Even when falling back on "recentering",
16136 position point in the window according to scroll-conservatively,
16137 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16139 (try_scrolling): When point is above the window, allow searching
16140 as far as scroll_max, or one screenful, to compute vertical
16141 distance from PT to the scroll margin position. This prevents
16142 try_scrolling from unnecessarily failing when
16143 scroll-conservatively is set to a value slightly larger than the
16144 window height. Clean up the case of PT below the margin at bottom
16145 of window: scroll_max can no longer be INT_MAX. When aggressive
16146 scrolling is in use, don't let point enter the opposite scroll
16147 margin as result of the scroll.
16148 (syms_of_xdisp) <scroll-conservatively>: Document the
16149 threshold of 100 lines for never-recentering scrolling.
16151 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16153 * dispextern.h (move_it_by_lines):
16154 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
16155 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
16156 (message_log_check_duplicate): Remove parameters `prev_bol' and
16157 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16158 (redisplay_internal): Remove parameter `preserve_echo_area',
16159 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16161 * indent.c (Fvertical_motion):
16162 * window.c (window_scroll_pixel_based, Frecenter):
16163 Don't pass `need_y_p' to `move_it_by_lines'.
16165 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16167 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16168 steal a few bits to be more compact.
16169 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16170 Remove unneeded casts.
16172 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16174 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16176 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16177 binding" message (bug#7967).
16179 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16181 Fix more problems found by GCC 4.6.0's static checks.
16183 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16184 Remove unused local var.
16186 * editfns.c (Fmessage_box): Remove unused local var.
16188 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16189 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16190 Omit unused local vars.
16191 * window.c (shrink_windows): Omit unused local var.
16192 * menu.c (digest_single_submenu): Omit unused local var.
16193 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16194 Omit unused local var.
16196 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16197 Don't assume string length fits in int.
16198 (keyremap_step, read_key_sequence): Use size_t for sizes.
16199 (read_key_sequence): Don't check last_real_key_start redundantly.
16201 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
16202 instead of alloca (Bug#8344).
16204 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16205 (Fbacktrace_frame): Don't assume nframes fits in int.
16207 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
16209 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
16212 * term.c (produce_glyphless_glyph): Remove unnecessary test.
16214 * cm.c (calccost): Turn while-do into do-while, for clarity.
16216 * keyboard.c (syms_of_keyboard): Use the same style as later
16217 in this function when indexing through an array. This also
16218 works around GCC bug 48267.
16220 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16222 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16224 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16225 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16227 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16228 This avoids undefined behavior on integer overflow, and is a bit
16229 more convenient anyway since it is compared to a size_t variable.
16231 Variadic C functions now count arguments with size_t, not int.
16232 This avoids an unnecessary limitation on 64-bit machines, which
16233 caused (substring ...) to crash on large vectors (Bug#8344).
16234 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
16235 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
16236 All variadic functions and their callers changed accordingly.
16237 (struct gcpro.nvars): Now size_t, not int. All uses changed.

16239 * editfns.c (general_insert_function): Likewise.
16240 * eval.c (struct backtrace.nargs, interactive_p)
16241 (internal_condition_case_n, run_hook_with_args, apply_lambda)
16242 (funcall_lambda, mark_backtrace): Likewise.
16243 * fns.c (concat): Likewise.
16244 * frame.c (x_set_frame_parameters): Likewise.
16245 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16246 0 if not found, not -1. All callers changed.
16248 * alloc.c (garbage_collect): Don't assume stack size fits in int.
16249 (stack_copy_size): Now size_t, not int.
16250 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
16252 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
16254 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
16255 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
16256 All callers changed.
16258 * lisp.h (multibyte_char_to_unibyte):
16259 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
16260 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
16261 * character.h (CHAR_TO_BYTE8):
16262 * cmds.c (internal_self_insert):
16263 * editfns.c (general_insert_function):
16264 * keymap.c (push_key_description):
16265 * search.c (Freplace_match):
16266 * xdisp.c (message_dolog, set_message_1): All callers changed.
16268 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
16270 * keyboard.c (safe_run_hook_funcall): New function.
16271 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
16272 don't set the hook to nil, but remove the offending function instead.
16273 (Qcommand_hook_internal): Remove, unused.
16274 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
16275 Vcommand_hook_internal.
16277 * eval.c (enum run_hooks_condition): Remove.
16278 (funcall_nil, funcall_not): New functions.
16279 (run_hook_with_args): Call each function through a `funcall' argument.
16280 Remove `cond' argument, now redundant.
16281 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
16282 (Frun_hook_with_args_until_failure): Adjust accordingly.
16283 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
16285 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
16287 * dispextern.h (string_buffer_position): Remove declaration.
16289 * print.c (strout): Remove parameter `multibyte', unused since
16290 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
16292 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
16293 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
16294 All callers changed.
16296 * w32.c (_wsa_errlist): Use braces for struct initializers.
16298 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
16299 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
16300 All callers changed.
16301 (string_buffer_position): Likewise. Also, make static (it's never
16302 used outside xdisp.c).
16303 (cursor_row_p): Remove parameter `w', unused since
16304 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

16306 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
16307 All callers changed.
16309 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
16311 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
16313 2011-03-27 Anders Lindgren <andlind@gmail.com>
16315 * nsterm.m (ns_menu_bar_is_hidden): New variable.
16316 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
16317 (ns_update_auto_hide_menu_bar): New functions.
16318 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

16322 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
16324 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
16326 * nsmenu.m (runDialogAt): Remove argument to timer_check.
16328 2011-03-27 Glenn Morris <rgm@gnu.org>
16330 * syssignal.h: Replace RETSIGTYPE with void.
16331 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
16332 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
16333 Replace SIGTYPE with void everywhere.
16334 * s/usg5-4-common.h (SIGTYPE): Remove definition.
16335 * s/template.h (SIGTYPE): Remove commented out definition.
16337 2011-03-26 Eli Zaretskii <eliz@gnu.org>
16339 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
16340 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
16342 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
16344 * w32.c (read_unc_volume): Use parameter `henum', instead of
16345 global variable `wget_enum_handle'.
16347 * keymap.c (describe_vector): Remove parameters `indices' and
16348 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
16349 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
16351 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
16353 * keyboard.c (timer_check): Remove parameter `do_it_now',
16354 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
16355 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
16356 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
16358 * keyboard.c (read_char):
16359 * w32menu.c (w32_menu_display_help):
16360 * xmenu.c (show_help_event, menu_help_callback):
16361 Adjust calls to `show_help_echo'.
16363 * gtkutil.c (xg_maybe_add_timer):
16364 * keyboard.c (readable_events):
16365 * process.c (wait_reading_process_output):
16366 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
16368 * insdel.c (adjust_markers_gap_motion):
16369 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
16370 (gap_left, gap_right): Don't call it.
16372 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

16416 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
16418 * w32term.c (x_set_glyph_string_clipping):
16419 Don't pass uninitialized region to CombineRgn.
16421 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
16423 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
16424 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
16425 (Fx_close_connection): Remove unused variable `i'.
16427 * w32font.c (w32font_draw): Return number of glyphs.
16428 (w32font_open_internal): Remove unused variable `i'.

16441 (uniscribe_font_driver): Add missing initializers.
16443 2011-03-23 Julien Danjou <julien@danjou.info>
16445 * term.c (Fsuspend_tty, Fresume_tty):
16446 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
16447 * window.c (temp_output_buffer_show):
16448 * insdel.c (signal_before_change):
16449 * frame.c (Fhandle_switch_frame):
16450 * fileio.c (Fdo_auto_save):
16451 * emacs.c (Fkill_emacs):
16452 * editfns.c (save_excursion_restore):
16453 * cmds.c (internal_self_insert):
16454 * callint.c (Fcall_interactively):
16455 * buffer.c (Fkill_all_local_variables):
16456 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
16458 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
16459 unconditionally since it does the check itself.
16461 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
16463 Fix more problems found by GCC 4.5.2's static checks.
16465 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16466 the first time through the loop, since we know p0 < p1 then.
16467 This also avoids a gcc -Wstrict-overflow warning.
16469 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16470 leading to a memory leak, possible in functions like
16471 load_charset_map_from_file that can allocate an unbounded number
16472 of objects (Bug#8318).
16474 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16475 that could (at least in theory) be that large.
16477 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16478 This is less likely to overflow, and avoids undefined behavior if
16479 overflow does occur. All callers changed. Use strtoul to scan
16480 for the unsigned long integer.
16481 (pint2hrstr): Simplify and tune code slightly.
16482 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
16484 * scroll.c (do_scrolling): Work around GCC bug 48228.
16485 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
16487 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
16488 This also avoids a warning with gcc -Wstrict-overflow.
16489 (validate_x_resource_name): Simplify count usage.
16490 This also avoids a warning with gcc -Wstrict-overflow.
16492 * fileio.c (Fcopy_file): Report error if fchown or fchmod
16495 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
16497 * process.c (Fmake_network_process): Use socklen_t, not int,
16498 where POSIX says socklen_t is required in portable programs.
16499 This fixes a porting bug on hosts like 64-bit HP-UX, where
16500 socklen_t is wider than int (Bug#8277).
16501 (Fmake_network_process, server_accept_connection):
16502 (wait_reading_process_output, read_process_output):
16505 * process.c: Rename or move locals to avoid shadowing.
16506 (list_processes_1, Fmake_network_process):
16507 (read_process_output_error_handler, exec_sentinel_error_handler):
16508 Rename or move locals.
16509 (Fmake_network_process): Define label "retry_connect" only if needed.
16510 (Fnetwork_interface_info): Fix pointer signedness.
16511 (process_send_signal): Add cast to avoid pointer signedness problem.
16512 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
16513 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
16515 Make tparam.h and terminfo.c consistent.
16516 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
16517 Include tparam.h instead, since it declares them.
16518 * cm.h (PC): Remove extern decl; tparam.h now does this.

16577 clobbering (Bug#8298).
16578 * sysdep.c (sys_subshell): Likewise.
16579 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
16581 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
16582 This should get cleaned up, so that child_setup has the
16583 same signature on all platforms.
16585 * callproc.c (call_process_cleanup): Now static.
16586 (relocate_fd): Rename locals to avoid shadowing.
16588 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

16747 (Fmemory_limit): Cast sbrk's returned value to char *.
16749 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

16755 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16756 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
16757 to use the following functions instead of these macros.
16758 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
16759 EMACS_INT, since callers assume the returned value fits in int.
16760 (upcase1): Likewise, for UPCASE_TABLE.
16761 (uppercasep, lowercasep, upcase): New static inline functions.
16762 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

16772 (regex_compile, re_match_2_internal): Mark locals as initialized.
16773 (RETALLOC_IF): Define only if needed.
16774 (WORDCHAR_P): Likewise. This one is never needed, but is used
16775 only in a comment talking about a compiler bug, so put inside
16776 the #if 0 of that comment.
16777 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
16778 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

16805 New macros, so that the caller can use some names other than
16806 gcpro1, gcpro2, etc.
16807 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
16809 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
16810 argument, for consistency with GCPRO2_VAR, etc: it is now the
16811 prefix of the variable, not the variable itself. All uses
16813 * dired.c (directory_files_internal, file_name_completion):
16814 Rename locals to avoid shadowing.
16816 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
16817 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
16818 dired.c's scmp function, had undefined behavior.
16819 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16820 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
16821 * buffer.h: ... to here, because these macros use current_buffer,
16822 and the new implementation with inline functions needs to have
16823 current_buffer in scope now, rather than later when the macros
16825 (downcase, upcase1): New static inline functions.
16826 (DOWNCASE, UPCASE1): Reimplement using these functions.
16827 This avoids undefined behavior in expressions like
16828 DOWNCASE (x) == DOWNCASE (y), which previously suffered
16829 from race conditions in accessing the global variables
16830 case_temp1 and case_temp2.
16831 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
16832 * lisp.h (case_temp1, case_temp2): Remove their decls.
16833 * character.h (ASCII_CHAR_P): Move from here ...
16834 * lisp.h: ... to here, so that the inline functions mentioned
16835 above can use them.

16842 (file_name_as_directory): Use const pointers when appropriate.
16843 (Fexpand_file_name): Likewise. In particular, newdir might
16844 point at constant storage, so make it a const pointer.

16846 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
16848 (Fset_file_times, Finsert_file_contents, auto_save_error):

16853 to avoid shadowing.
16855 * marker.c (bytepos_to_charpos): Remove; unused.
16857 * lisp.h (verify_bytepos, count_markers): New decls,
16858 so that gcc does not warn that these functions aren't declared.
16860 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
16861 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
16862 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
16863 (copy_text): Remove unused local var.

16868 * buffer.c (fix_overlays_before): Mark locals as initialized.
16869 (fix_start_end_in_overlays): Likewise. This function should be
16870 simplified by using pointers-to-pointers, but that's a different
16872 (switch_to_buffer_1): Now static.
16873 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
16874 (report_overlay_modification): Rename locals to avoid shadowing.

16877 Fix pointer signedness issue.

16879 to suppress a gcc -Wclobbered warning that does not seem to be right.
16880 (MAXPATHLEN): Define only if needed.
16882 * process.c (serial_open, serial_configure): Move decls from here ...
16883 * systty.h: ... to here, so that they can be checked.
16885 * fns.c (get_random, seed_random): Move extern decls from here ...
