3 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5 * nsfns.m (XParseGeometry): Remove.
6 (Fx_create_frame): Call x_set_offset to correctly interpret
9 * frame.c (read_integer, XParseGeometry): Moved from w32xfns.c.
10 (Fx_parse_geometry): If there is a space in string, call
11 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
13 2012-09-17 Eli Zaretskii <eliz@gnu.org>
15 * search.c (scan_buffer): Use character positions in calls to
16 region_cache_forward and region_cache_backward, not byte
17 positions. (Bug#12196)
19 * w32term.c (w32_read_socket): Set pending_signals to 1, like
20 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
22 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
23 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
24 emacs_blocked_malloc, now deleted.
26 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
28 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
29 The workaround was for improving performance on Solaris 2.4, but
30 is getting in the way now. Emacs will still work if someone is
31 still running Solaris 2.4 in a museum somewhere; Sun dropped
32 support for Solaris 2.4 in 2003.
33 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
34 * process.c (create_process) [HAVE_WORKING_VFORK]:
35 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
36 since Emacs no longer uses vfork on that platform.
38 2012-09-17 Glenn Morris <rgm@gnu.org>
40 * emacs.c: Use COPYRIGHT.
42 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
44 Remove configure's --without-sync-input option (Bug#12450).
45 When auditing signal-handling in preparation for cleaning it up,
46 I found that SYNC_INPUT has race conditions and would be a real
47 pain to fix. Since it's an undocumented and deprecated
48 configure-time option, now seems like a good time to remove it.
49 Also see <http://bugs.gnu.org/11080#16>.
50 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
51 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
52 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
54 (check_depth) [XMALLOC_OVERRUN_CHECK]:
55 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
56 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
57 (dont_register_blocks, bytes_used_when_reconsidered)
58 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
59 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
60 [!SYSTEM_MALLOC && !SYNC_INPUT]:
61 Remove. All uses removed.
62 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
63 implementation, one that depends on whether the new macro
64 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
66 * atimer.c (run_timers, handle_alarm_signal):
67 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
68 (handle_async_input, process_pending_signals)
69 (handle_input_available_signal, init_keyboard):
70 * nsterm.m (ns_read_socket):
71 * process.c (wait_reading_process_output):
72 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
73 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
75 * xterm.c (XTread_socket):
77 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
78 * eval.c (handling_signal): Remove. All uses removed.
79 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
80 All uses replaced with the SYNC_INPUT version.
81 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
83 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
86 * font.c (Ffont_shape_gstring): Remove unused local.
88 2012-09-16 Glenn Morris <rgm@gnu.org>
90 * Makefile.in (clean): No longer run nextstep's clean.
92 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
94 (ns-app): Move here from ns.mk, and simplify.
95 (clean): Simplify nextstep entry.
98 2012-09-16 Kenichi Handa <handa@gnu.org>
100 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
101 not covert the last few charactes.
103 2012-09-16 Kenichi Handa <handa@gnu.org>
105 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
106 here, but just check the validity of glyphs in the glyph-string.
108 2012-09-16 Martin Rudalics <rudalics@gmx.at>
110 * window.c (Fwindow_parameter, Fset_window_parameter): Accept
111 any window as argument (Bug#12452).
113 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
115 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
116 to ns_term_init to avoid memory leak.
118 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
119 explicit retain/release.
120 (ns_term_init): Only allow one display. Initialize outerpool and
123 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
125 Port _setjmp fix to POSIXish hosts as well as Microsoft.
126 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
127 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
128 the Microsoft problem in a different way, by altering ../nt/config.nt.
130 2012-09-15 Eli Zaretskii <eliz@gnu.org>
145 * w16select.c: Remove inclusion of setjmp.h, as it is now included
146 by lisp.h. This completes removal of setjmp.h inclusion
147 erroneously announced in the previous commit. (Bug#12446)
149 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
152 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
153 not defined as a macro. The latter happens on MS-Windows.
156 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
158 Port better to POSIX hosts lacking _setjmp (Bug#12446).
159 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
160 Some instances of '#include <setjmp.h>' removed, if the
161 only reason for the instance was because "lisp.h" was included.
162 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
163 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
164 and _longjmp with the new symbols. Emacs already uses _setjmp if
165 available, so this change affects only POSIXish hosts that have
166 sigsetjmp but not _setjmp, such as some versions of Solaris and
167 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
168 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
169 (png_load_body) [HAVE_PNG]:
170 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
171 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
172 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
173 since PNG requires jmp_buf. This is the only exception to the
174 general rule that we now use sys_setjmp and sys_longjmp.
175 This exception is OK since this code does not change the signal
176 mask or longjmp out of a signal handler.
178 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
180 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
181 Include "syssignal.h", for 'main_thread'.
183 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
185 Avoid out-of-range marker position (Bug#12426).
186 * insdel.c (replace_range, replace_range_2): Adjust
187 markers before overlays, as suggested by comments.
188 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
189 Remove redundant check before calling offset_intervals.
191 2012-09-14 Martin Rudalics <rudalics@gmx.at>
193 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
194 current buffer (Bug#12387).
196 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
198 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
200 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
202 Use a more backwards-compatible timer format (Bug#12430).
203 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
204 vector element, not from the 4th, since PSECS is now at the end.
205 (Fcurrent_idle_time): Doc fix.
207 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
209 Function to mark objects and remove killed buffers at once.
210 * alloc.c (discard_killed_buffers): Rename to ...
211 (mark_discard_killed buffers) ... new name. Add marking
212 of remaining objects. Fix comment. Adjust users.
213 (mark_object): Do not touch frame buffer lists here.
214 * frame.c (delete_frame): Reset frame buffer lists here.
216 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
218 Better workaround for GNOME bug when --enable-gcc-warnings.
219 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
220 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
221 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
223 Simplify SIGIO usage (Bug#12408).
224 The code that dealt with SIGIO was crufty and confusing, e.g., it
225 played tricks like "#undef SIGIO" but these tricks were not used
226 consistently. Simplify mostly by not #undeffing standard symbols,
227 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
228 or not as we please) rather than "defined SIGIO" (standard symbol
229 that we probably shouldn't #undef).
230 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
231 Modules that need it can include it.
232 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
233 * dispextern.h (ignore_sigio): New decl.
234 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
235 unconditionally, since it's now a no-op if !USABLE_SIGIO.
236 * emacs.c (shut_down_emacs):
237 * keyboard.c (kbd_buffer_store_event_hold):
238 Use ignore_sigio rather than invoking 'signal' directly.
239 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
241 (FIONREAD, SIGIO): Do not #undef.
242 (tty_read_avail_input): Use #error rather than a syntax error.
243 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
244 for I_PIPE, used by SETUP_SLAVE_PTY.
245 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
246 * sysdep.c (croak): Remove; no longer needed. This bit of
247 temporary code, with Fred N. Fish's comment that it's temporary,
248 has been in Emacs since at least 1992!
249 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
250 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
251 * syssignal.h (croak): Remove decl.
252 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
253 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
254 now that we're termios-only.
255 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
256 * term.c (dissociate_if_controlling_tty): Use #error rather than
259 Work around GCC and GNOME bugs when --enable-gcc-warnings.
260 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
261 to work around GNOME bug 683906.
262 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
263 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
264 This works around GCC bug 54561.
266 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
268 More fixes for 'volatile' and setjmp/longjmp.
269 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
270 * image.c (struct png_load_context) [HAVE_PNG]: New type.
271 (png_load_body) [HAVE_PNG]:
272 (jpeg_load_body) [HAVE_JPEG]:
273 New function, with most of the old parent function's body.
274 (png_load) [HAVE_PNG]:
275 (jpeg_load) [HAVE_JPEG]:
276 Invoke the new function, to avoid longjmp munging our locals.
277 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
278 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
279 longjmp is passed 2, as the C standard doesn't guarantee this.
280 Instead, store the failure code into mgr->failure_code.
282 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
284 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
285 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
286 (syms_of_keyboard): Remove support for unread-command-char.
288 2012-09-12 Eli Zaretskii <eliz@gnu.org>
290 * w32proc.c (sys_kill): If PID is our process ID and the signal is
291 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
292 violation. (Bug#12426)
294 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
296 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
298 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
300 * eval.c: Add `inhibit-debugger'.
301 (Qinhibit_debugger): New symbol.
302 (call_debugger): Bind it instead of Qdebug_on_error.
303 (maybe_call_debugger): Test Vinhibit_debugger.
304 (syms_of_eval): Define inhibit-debugger.
305 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
306 (syms_of_xdisp): Remove inhibit-debug-on-message.
308 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
310 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
311 If a nonvolatile local variable is written before a _longjmp to
312 the frame containing the variable, and is read after the _longjmp,
313 the value read is indeterminate. Some local variables of type
314 'struct handler' and 'struct catchtag' are used in this way, so
315 mark each of their slots as volatile if the slot can be set before
316 _longjmp and read afterwards.
317 * lisp.h (struct handler): var and chosen_clause are now volatile.
318 (struct catchtag): val, next, and pdlcount are now volatile.
320 * bidi.c (bidi_push_it, bidi_pop_it):
321 * fns.c (copy_hash_table):
322 * image.c (define_image_type):
323 * keyboard.c (kbd_buffer_store_event_hold):
324 * process.c (Fprocess_send_eof):
325 * xfaces.c (x_create_gc) [HAVE_NS]:
326 * xgselect.c (xg_select):
327 Prefer assignment to memcpy when either will do.
329 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
330 Use pointer-to-a-pointer to simplify and avoid a NILP check each
331 time an item is removed. No need to mark this function 'inline';
332 the compiler knows better than we do.
334 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
336 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
337 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
338 to change_frame_size (Bug#12388).
339 (windowDidResize:): Pass YES to updateFrameSize.
341 * nsterm.h: Add delay parameter to updateFrameSize.
343 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
345 Discard killed buffers from deleted window and frame objects.
346 This reduces an amount of references to killed buffers and
347 helps GC to reclaim them faster.
348 * alloc.c (discard_killed_buffers): New function.
349 (mark_object): Use it for deleted windows and frames.
350 (mark_object): If symbol's value is set up for a killed buffer
351 or deleted frame, restore it's global binding.
352 * data.c (swap_in_global_binding): Add GC notice.
353 (swap_in_symval_forwarding): Use convenient set_blv_where.
354 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
355 * window.h: ... to here.
357 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
359 Convenient macro to check whether the buffer is live.
360 * buffer.h (BUFFER_LIVE_P): New macro.
361 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
362 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
364 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
366 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
367 composition cases (Bug#12364).
369 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
370 overhang of succeeding glyphs overlapping box cursor.
372 * w32term.c (x_draw_glyph_string): Likewise.
374 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
376 Simplify, document, and port floating-point (Bug#12381).
377 The porting part of this patch fixes bugs on non-IEEE platforms
378 with frexp, ldexp, logb.
379 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
381 * floatfns.c: Simplify discussion of functions that Emacs doesn't
382 support, by removing commented-out code and briefly listing the
383 C89 functions excluded. The commented-out stuff was confusing
384 maintenance, e.g., we thought we needed cbrt but it was commented out.
385 (logb): Remove decl; no longer needed.
386 (isfinite): New macro, if not already supplied.
387 (isnan): Don't replace any existing macro.
388 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
389 are present on all C89 platforms.
390 (Ffrexp): Do not special-case zero, as frexp does the right thing
392 (Flogb): Do not use logb, as it doesn't have the desired meaning
393 on hosts that use non-base-2 floating point. Instead, stick with
394 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
395 frexp, to avoid getting an unspecified result.
397 * xdisp.c (Qinhibit_debug_on_message): Now static.
399 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
401 * nsterm.m (ns_update_begin): Set clip path to whole view by using
402 NSBezierPath (Bug#12131).
404 2012-09-10 Chong Yidong <cyd@gnu.org>
406 * fns.c (Fdelq, Fdelete): Doc fix.
408 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
410 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
411 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
413 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
415 * lisp.h (make_lisp_ptr): New macro to replace XSET.
416 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
419 2012-09-09 Eli Zaretskii <eliz@gnu.org>
421 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
422 left fringe if the window has a left margin. This avoids leaving
423 traces of the cursor because its leftmost pixel is not drawn over.
425 * dispnew.c (update_window_line): When the left margin area of a
426 screen line is updated, set the redraw_fringe_bitmaps_p flag of
427 that screen line. (Bug#12277)
429 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
431 Assume C89 or later for math functions (Bug#12381).
432 This simplifies the code, and makes it a bit smaller and faster,
433 and (most important) makes it easier to clean up signal handling
434 since we can stop worring about floating-point exceptions in
435 library code. That was a problem before C89, but the problem
436 went away many years ago on all practical Emacs targets.
437 * data.c, image.c, lread.c, print.c:
438 Don't include <math.h>; no longer needed.
439 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
440 might be autoconfigured, as that never happens.
442 * doprnt.c (DBL_MAX_10_EXP):
444 Remove. C89 or later always defines these.
445 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
446 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
447 (arith_error, domain_error, domain_error2):
448 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
449 no longer needed -- we simply return what C returns. All uses removed.
450 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
452 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
453 Remove. All uses expanded, as these macros are no longer used
454 more than once and are now more trouble than they're worth.
455 (Ftan): Use tan, not sin / cos.
456 (Flogb): Assume C89 frexp.
457 (fmod_float): Assume C89 fmod.
458 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
459 (init_floatfns): Remove. All uses removed.
461 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
463 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
464 compositeToPoint for OSX < 10.6 (Bug#12390).
466 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
468 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
469 This produces more-accurate results.
471 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
473 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
476 2012-09-08 Chong Yidong <cyd@gnu.org>
478 * syntax.c (Fstring_to_syntax): Doc fix.
480 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
482 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
483 in the internal border.
484 (x_set_window_size): Remove static variables and their usage.
485 (ns_redraw_scroll_bars): Fix NSTRACE arg.
486 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
487 fringe/internal border adjustment (Bug#11052).
488 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
489 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
490 (ns_fix_rect_ibw): Remove.
491 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
492 (ns_dumpglyphs_box_or_relief): Ditto.
493 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
495 (ns_dumpglyphs_image): Ditto.
496 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
498 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
499 their usage. Add fringe_extended_p and its use as in other terms.
500 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
501 scroll bar was removed.
502 (updateFrameSize): New function.
503 (windowDidResize): Move code to updateFrameSize and call it.
505 * nsterm.h (EmacsView): Add updateFrameSize.
507 2012-09-07 Chong Yidong <cyd@gnu.org>
509 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
511 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
513 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
515 More signal-handler cleanup (Bug#12327).
516 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
517 Problem introduced when merging patches. Noted by Eli Zaretskii in
518 <http://bugs.gnu.org/12327#67>.
519 * floatfns.c: Comment fix.
520 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
521 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
522 and anyway the declaration is harmless even if SIGDANGER is not defined.
523 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
524 defined BROKEN_FIONREAD). systty.h formerly did this, but other
525 source files not surprisingly expected syssignal.h to define, or
526 not define, SIGIO, and it's cleaner to do it that way, for consistency.
527 Include <sys/ioctl.h>, for FIONREAD.
528 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
529 This eliminates a problem whereby other files mysteriously had
530 to include "syssignal.h" before including "systty.h" if they
531 wanted to use "#ifdef SIGIO".
533 2012-09-07 Eli Zaretskii <eliz@gnu.org>
535 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
537 * w32.c (sigemptyset): Empty the set.
538 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
540 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
542 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
544 * alloc.c (mark_buffer): Revert unsafe marking optimization.
545 (mark_object): Likewise for frame objects.
547 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
549 * syssignal.h (handle_on_main_thread): Always declare,
550 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
551 This ports to platforms without HAVE_PTHREAD.
553 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
555 Signal-handler cleanup (Bug#12327).
556 Emacs's signal handlers were written in the old 4.2BSD style with
557 sigblock and sigmask and so forth, and this led to some
558 inefficiencies and confusion. Rewrite these to use
559 pthread_sigmask etc. without copying signal sets around. Also,
560 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
561 'signal', and instead use functions that do not attempt to take
562 over the system name space. This patch causes Emacs's text
563 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
564 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
565 Do not include <signal.h> or "syssignal.h", as these
566 modules do not use signals.
567 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
568 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
569 Do not include <signal.h>, as "syssignal.h" does that for us now.
570 * atimer.c (sigmask_atimers): New function.
571 (block_atimers, unblock_atimers): New functions,
572 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
574 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
575 no longer needed here.
576 * emacs.c (main): Inspect existing signal handler with sigaction,
577 so that there's no need to block and unblock SIGHUP.
578 * sysdep.c (struct save_signal): New member 'action', replacing
579 old member 'handler'.
580 (save_signal_handlers, restore_signal_handlers):
581 Use sigaction instead of 'signal' to save and restore.
582 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
583 New function. All users of 'signal' modified to use set_sighandler
584 if they're writeonly, and to use sys_signal if they're read+write.
585 (emacs_sigaction_init, forwarded_signal): New functions.
586 (sys_signal): Remove. All uses replaced by calls to sigaction
587 and emacs_sigaction_init, or by direct calls to 'signal'.
588 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
589 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
590 all uses replaced by pthread_sigmask etc. calls.
591 * syssignal.h: Include <signal.h>.
592 (emacs_sigaction_init, forwarded_signal): New decls.
593 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
594 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
595 (sigmask, sys_sigmask): Remove; no longer needed.
596 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
597 (sigblock, sigunblock, sigfree):
598 (sigsetmask) [!defined sigsetmask]:
599 Remove. All uses replaced by pthread_sigmask.
600 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
601 no longer need to be replaced, and its typical old uses
602 are now done via emacs_sigaction_init and sigaction.
603 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
604 (sys_sigdel): Remove; unused.
605 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
607 2012-09-06 Eli Zaretskii <eliz@gnu.org>
609 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
610 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
612 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
614 Explicitly mark buffer_defaults and buffer_local_symbols.
615 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
616 mark_local_symbols here.
617 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
618 since special buffers aren't marked here any more.
619 (allocate_buffer): Chain new buffer with all_buffers here...
620 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
622 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
623 (syms_of_buffer): Remove staticpro of the above.
624 (init_buffer_once): Set names for buffer_defaults and
625 buffer_local_symbols.
627 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
629 Use bool for booleans in font-related modules.
630 * font.c (font_intern_prop, font_style_to_value)
631 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
632 (generate_otf_features, font_check_otf_features, font_check_otf)
633 (font_match_p, font_list_entities, font_at):
634 * fontset.c (fontset_id_valid_p, reorder_font_vector
635 (fontset_find_font, Fset_fontset_font)
636 (face_suitable_for_char_p) [0]:
637 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
638 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
639 (m17n_flt_initialized, ftfont_shape_by_flt):
640 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
641 * nsfont.m (nsfont_draw):
642 * w32font.c (w32font_draw):
643 * w32term.c (x_draw_glyphless_glyph_string_foreground):
644 Use bool for booleans.
645 * font.h: Adjust to above API changes.
646 (struct font, struct font_driver, struct font_driver_list):
647 Use bool for booleans.
648 (struct font): Remove useless member encoding_type.
650 * fontset.c, xftfont.c: Omit unnecessary static decls.
652 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
654 * alloc.c (mark_object): Revert window marking code
655 since it's unsafe for the Fset_window_configuration.
657 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
659 Fix race conditions with signal handlers and errno (Bug#12327).
660 Be more systematic about preserving errno whenever a signal
661 handler returns, even if it's not in the main thread. Do this by
662 renaming signal handlers to distinguish between signal delivery
663 and signal handling. All uses changed.
664 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
665 * data.c (deliver_arith_signal): Rename from arith_error.
666 * dispnew.c (deliver_window_change_signal): Rename from
667 window_change_signal.
668 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
669 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
670 * keyboard.c (deliver_input_available_signal): Rename from
671 input_available_signal.
672 (deliver_user_signal): Rename from handle_user_signal.
673 (deliver_interrupt_signal): Rename from interrupt_signal.
674 * process.c (deliver_pipe_signal): Rename from send_process_trap.
675 (deliver_child_signal): Rename from sigchld_handler.
676 * atimer.c (handle_alarm_signal):
677 * data.c (handle_arith_signal):
678 * dispnew.c (handle_window_change_signal):
679 * emacs.c (handle_fatal_signal, handle_danger_signal):
680 * keyboard.c (handle_input_available_signal):
681 * keyboard.c (handle_user_signal, handle_interrupt_signal):
682 * process.c (handle_pipe_signal, handle_child_signal):
683 New functions, with the actual signal-handling code taken from the
684 original respective signal handlers, sans the sporadic attempts to
685 preserve errno, since that's now done by handle_on_main_thread.
686 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
687 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
688 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
690 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
691 Move initialization of main_thread to sysdep.c's init_signals.
692 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
693 our usage, and simplifies the mainline code.
694 (record_child_status_change): New static function, as a helper
695 for handle_child_signal, and with most of the old child handler's
697 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
698 (handle_child_signal): Use the above.
699 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
700 Moved here from emacs.c.
701 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
702 code moved here from emacs.c's main function.
703 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
704 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
705 lets callers save and restore errno properly.
707 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
709 Remove redundant or unused things here and there.
710 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
711 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
712 * editfns.c (Fcompare_buffer_substrings): Likewise.
713 * frame.h (struct terminal, struct font_driver_list):
714 Remove redundant declarations.
715 * window.h (Qleft, Qright): Likewise.
717 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
719 Do not mark objects from deleted buffers, windows and frames.
720 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
721 (mark_object): Likewise for windows and frames.
723 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
725 * alloc.c (valid_lisp_object_p): Treat killed buffers,
726 buffer_defaults and buffer_local_symbols as valid objects.
727 Return special value to denote them.
729 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
731 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
732 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
733 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
734 (file_name_absolute_p, Fsubstitute_in_file_name):
735 (check_executable, check_writable, Ffile_accessible_directory_p)
736 (Fset_file_selinux_context, Fdefault_file_modes)
737 (Finsert_file_contents, choose_write_coding_system)
738 (Fwrite_region, build_annotations, a_write, e_write)
740 * filelock.c (boot_time_initialized, get_boot_time)
741 (get_boot_time_1, lock_file_1, within_one_second):
742 * floatfns.c (in_float):
743 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
744 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
745 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
746 * lisp.h (struct Lisp_Hash_Table.cmpfn):
747 * window.c (compare_window_configurations):
748 Use bool for booleans.
749 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
750 (Fdefault_file_modes): Now mode_t, not int, for modes.
751 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
752 (internal_delete_file): Now returns void, not a (boolean) int,
753 since nobody was looking at the return value.
754 * lisp.h, window.h: Adjust to above API changes.
756 * xdisp.c (set_message): Simplify and reindent last change.
758 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
760 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
762 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
764 * eval.c (call_debugger): Make the function non-static so that we
765 can call it from set_message.
767 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
768 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
770 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
772 Give more-useful info on a fatal error (Bug#12328).
773 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
774 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
775 of doing the work ourselves.
776 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
778 (fatal_error_backtrace): New function, taken from the guts
779 of the old fatal_error_signal, but with a new option to output
781 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
782 info about the signal than just its number.
783 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
784 * sysdep.c: Include <execinfo.h>
785 (emacs_backtrace): New function, taken partly from the previous
786 code of the 'die' function.
787 (emacs_abort): Call fatal_error_backtrace rather than abort.
789 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
791 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
792 eager (load-time) macro-expansion.
793 * lisp.mk (lisp): Add macroexp.
795 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
797 Simplify redefinition of 'abort' (Bug#12316).
798 Do not try to redefine the 'abort' function. Instead, redo
799 the code so that it calls 'emacs_abort' rather than 'abort'.
800 This removes the need for the NO_ABORT configure-time macro
801 and makes it easier to change the abort code to do a backtrace.
802 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
803 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
804 Remove; sysdep.c's emacs_abort now takes its place.
805 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
806 'abort' changed to use 'emacs_abort'.
807 * msdos.c (dos_abort) [defined abort]: Remove; not used.
808 (abort) [!defined abort]: Rename to ...
809 (emacs_abort): ... new name.
810 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
811 the place of the old 'abort' in emacs.c.
812 * w32.c, w32fns.c (abort): Do not #undef.
813 * w32.c (emacs_abort): Rename from w32_abort.
815 2012-09-04 Eli Zaretskii <eliz@gnu.org>
817 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
818 offsets[j].dv, since the y axis of the screen coordinates points
819 down, while the y axis of the font definition coordinates points
820 up. This fixes display of Arabic diacritics such as KASRA and
821 KASRATAN. (Bug#11860)
823 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
825 Be more systematic about _setjmp vs setjmp.
826 * alloc.c (test_setjmp, mark_stack):
827 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
828 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
829 (png_load, my_error_exit, jpeg_load):
830 * process.c (send_process_trap, send_process):
831 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
832 The underscored versions are up to 30x faster on some hosts.
833 Formerly, the code used setjmp+longjmp sometimes and
834 _setjmp+_longjmp at other times, with no particular reason to
835 prefer setjmp+longjmp.
837 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
839 Fix minor problem found by static checking.
840 * buffer.c (Fdelete_all_overlays): Return nil.
842 2012-09-03 Martin Rudalics <rudalics@gmx.at>
844 * buffer.c (Fdelete_all_overlays): New function.
846 2012-09-03 Chong Yidong <cyd@gnu.org>
848 * gtkutil.c: Add extern decl for Qxft.
850 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
852 * emacs.c, eval.c: Use bool for boolean.
853 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
854 (malloc_using_checking) [DOUG_LEA_MALLOC]:
855 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
856 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
857 (main, decode_env_path, Fdaemon_initialized):
858 * eval.c (call_debugger, Finteractive_p, interactive_p):
859 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
860 (maybe_call_debugger, Fbacktrace):
861 * process.c (read_process_output, exec_sentinel):
862 Use bool for booleans.
863 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
865 * eval.c (interactive_p): Omit always-true boolean argument
866 EXCLUDE_SUBRS_P. All callers changed.
867 * dispextern.h, lisp.h: Reflect above API changes.
868 * firstfile.c (dummy): Use the address of 'main', whose signature
869 won't change, instead of the address of 'initialize', whose
870 signature just changed from int to bool.
871 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
872 * msdos.c (fatal_error_in_progress): ... from here.
873 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
875 (redisplay_internal, unwind_redisplay): Simply clear
876 REDISPLAYING_P when unwinding, instead of saving its previous,
877 always-false value and then restoring it.
879 Clean up some extern decls.
880 Mostly, this hoists extern decls out of .c files and into .h files.
881 That way, we're more likely to catch errors if the interfaces change.
882 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
883 declare xg_mark_data.
884 * dispextern.h (x_frame_parm_handlers):
886 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
887 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
888 (Qultra_bold, Qoblique, Qitalic):
889 Move extern decl here from .c file.
890 * alloc.c (xg_mark_data) [USE_GTK]:
892 * eval.c (Qlexical_binding):
893 * fns.c (time) [!HAVE_UNISTD_H]:
894 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
895 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
896 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
897 * lread.c (Qinternal_interpreter_environment):
898 * minibuf.c (Qbuffer):
899 * process.c (QCfamily, QCfilter):
900 * widget.c (free_frame_faces):
901 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
902 * xfont.c (x_clear_errors):
903 * xterm.c (x_frame_parm_handlers):
904 Remove now-redundant extern decls.
905 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
906 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
908 * xfaces.c: Remove unnecessary static decls.
909 * xterm.c (updating_frame): Remove decl of nonexistent object.
911 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
912 when building globals.h, as the objects that are not built on
913 this host are not needed to compile C files on this host.
915 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
917 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
919 * frame.h: Add missing prototype for x_wm_set_size_hint.
921 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
923 * doc.c, editfns.c, insdel.c, intervals.c: Use bool for boolean.
924 * doc.c (read_bytecode_char, get_doc_string, reread_doc_file)
925 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)

967 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
968 more than one grapheme cluster passed to the shaper: compute the
969 offset adjustment values separately for each cluster. (Bug#11860)
971 * image.c: Restore mistakenly removed inclusion of w32.h. Without
972 it, GCC doesn't see prototypes of w32_delayed_load, and complains
973 about implicit conversions from integer to pointer.

1093 for GCC 4.7.1 x86-64.
1095 2012-08-30 Glenn Morris <rgm@gnu.org>
1097 * lread.c (init_lread): For out-of-tree builds, only add the
1098 source directory's site-lisp dir to the load-path if it exists,
1099 consistent with in-tree builds. (Bug#12302)
1101 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

1334 * lisp.h (ASET): Remove attempt to detect side effects.
1335 It was meant to be temporary and it often doesn't work,
1336 because when IDX has side effects the behavior of IDX==IDX
1337 is undefined. See Stefan Monnier in
1338 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.

1349 as that's faster and simpler than static storage. Don't bother
1350 with the g_main_context_query overhead if g_main_context_pending
1351 says no events are pending.

1354 All uses and decls removed.

1382 (getenv_internal, sync_process_alive, call_process_exited):
1383 * lisp.h (USE_SAFE_ALLOCA):
1384 Use bool for booleans, instead of int.
1385 * lisp.h, process.h: Adjust prototypes to match above changes.
1386 * callint.c (Fcall_interactively): Don't assume the mark's
1387 offset fits in 'int'.
1389 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1391 * buffer.c, buffer.h: Use bool for boolean.
1392 * buffer.c (reset_buffer_local_variables)
1393 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1394 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
1395 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
1396 (overlay_touches_p, overlay_strings, Foverlay_put)
1397 (report_overlay_modification, call_overlay_mod_hooks):
1398 (mmap_enlarge, mmap_set_vars):
1399 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1400 Use bool for booleans, instead of int.
1401 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1402 since the 1-or-0 return value is always ignored anyway.
1403 (mmap_initialized_p):
1404 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1405 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1407 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1409 * bidi.c: Use bool for boolean.
1410 This is a bit more readable, and makes the text segment of bidi.o
1411 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1412 Presumably it's faster too.
1413 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1415 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1416 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1417 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1418 (bidi_explicit_dir_char, bidi_level_of_next_char)
1419 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1420 Use bool for booleans, instead of int.
1421 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1422 (bidi_unshelve_cache): Adjust decls to match code.
1424 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1426 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1429 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1431 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1432 * atimer.h: Include <stdbool.h>.
1434 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1436 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1437 compile time tests instead of run time tests on systems that do
1439 (FRAME_MAC_P): Remove leftover from deleted code.
1440 * frame.c (syms_of_frame): Remove leftover from deleted code.
1442 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
1444 * nsterm.m (insertText:): Don't clear modifiers if code is space.
1446 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1448 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1449 Otherwise, the compiler complains about (A?B:C) where B is void
1450 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1451 (fontset_add): Return void, for FONTSET_ADD.
1453 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1455 * alloc.c: Use bool for booleans.
1456 (gc_in_progress, abort_on_gc)
1457 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1458 (dont_register_blocks) [GC_MALLOC_CHECK]:
1459 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1460 (check_string_bytes, make_specified_string, memory_full)
1461 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1462 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1463 (mark_stack, valid_pointer_p, make_pure_string)
1464 (Fgarbage_collect, survives_gc_p, gc_sweep):
1465 Use bool for booleans, instead of int.
1466 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1467 Remove unused local.
1468 * alloc.c (PURE_POINTER_P):
1469 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1470 * editfns.c (Fformat):
1471 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1473 * fns.c (sweep_weak_table):
1474 * lisp.h (suppress_checking, push_message, survives_gc_p)
1475 (make_pure_string, gc_in_progress, abort_on_gc):
1476 * lread.c (readchar, read1):
1477 * print.c (Fprin1_to_string):
1478 * xdisp.c (push_message):
1479 Use bool for booleans affected directly or indirectly by
1482 Make recently-introduced setters macros.
1483 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1484 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1485 (set_fontset_default, set_fontset_fallback): Rename from their
1486 upper-case counterparts, and make them functions rather than macros.
1487 This is more consistent with the other recently-introduced setters.
1488 These don't need to be inline, since they're local.
1490 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1492 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1493 the loop (Bug#12247).
1495 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1497 * lisp.h (vcopy): Use memcpy rather than our own loop.
1498 This fixes a performance regression introduced by the recent
1499 addition of vcopy. This means 'vcopy' will need to be modified
1500 for a copying collector, but that's OK. Also, tighten the
1501 checking in the assertion.
1503 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1505 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1506 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1507 non-base glyph for the width of the base character, according to
1508 what x_draw_composite_glyph_string_foreground expects.
1509 Generate WADJUST value according to composition_gstring_width's
1510 expectations, to produce correct width of the composed character.
1511 Reverse the sign of the DU offset produced by ScriptPlace.
1513 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1515 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1517 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1519 Avoid direct writes to contents member of struct Lisp_Vector.
1520 * lisp.h (vcopy): New function to copy data into vector.

1522 * fns.c (Ffillarray): Use ASET.
1523 * keyboard.c (timer_check_2): Use AREF and ASET.
1524 (append_tool_bar_item, Frecent_keys): Use vcopy.
1525 * lread.c (read_vector): Use ASET.
1526 * msdos.c (Frecent_doskeys): Use vcopy.
1527 * xface.c (Finternal_copy_lisp_face): Use vcopy.
1528 (Finternal_merge_in_global_face): Use ASET and vcopy.

1534 the position of its buffer's point.
1535 (Fset_window_point): For the selected window always go in its
1536 buffer to the specified position.
1538 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1540 Setter macros for fontsets.
1541 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1542 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1543 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1546 2012-08-20 Glenn Morris <rgm@gnu.org>
1548 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1549 Don't assume that `ln -f' works.
1551 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1553 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1554 and later about non-assignments with no effect. See discussion at
1555 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1558 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1560 Inline setter functions for Lisp_Objects slots of struct specbinding.
1561 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
1564 2012-08-20 Martin Rudalics <rudalics@gmx.at>
1566 * window.c (select_window): Always make selected window's buffer
1569 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1571 Use AREF and ASET for docstrings of category tables.
1572 * category.h (CATEGORY_DOCSTRING): Use AREF.
1573 (SET_CATEGORY_DOCSTRING): Use ASET.
1574 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
1576 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1578 Inline setter functions for hash table members.
1579 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
1580 (set_hash_hash, set_hash_index): Rename with _slot suffix.
1581 (set_hash_key_and_value, set_hash_index, set_hash_next)
1582 (set_hash_hash): New functions.
1583 * charset.c, fns.c: Adjust users.
1585 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1587 Inline getter and setter functions for per-buffer values.
1588 * buffer.h (per_buffer_default, set_per_buffer_default)
1589 (per_buffer_value, set_per_buffer_value): New functions.
1590 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
1591 * buffer.c, data.c: Adjust users.
1593 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
1595 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
1597 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
1599 Rely on <config.h> + <unistd.h> to declare 'environ',
1600 as gnulib does this if the system doesn't.
1601 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
1602 Remove declaration. MS-Windows declares it on stdlib.h which is
1603 included by conf_post.h.
1604 * emacs.c (environ) [DOUG_LEA_MALLOC]:
1605 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
1606 * vm-limit.c: Include <unistd.h>, for 'environ'.
1608 * unexaix.c, unexcoff.c: Include "mem-limits.h".
1609 (start_of_data): Remove decl; mem-limits.h provides it.
1611 * xdisp.c (handle_invisible_prop): Make it a bit faster
1612 and avoid a gcc -Wmaybe-uninitialized diagnostic.
1614 2012-08-19 Chong Yidong <cyd@gnu.org>
1616 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
1619 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
1621 * .gdbinit: Use call instead of set when calling a function in the
1624 * data.c (set_internal): Don't use set_blv_found.
1625 (Fkill_local_variable): Likewise.
1627 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
1629 * nsfont.m (ns_ascii_average_width): Ensure the string
1630 ascii_printable is initialized with a null-terminated character
1631 array. Otherwise, it can contain undesired extra characters.
1633 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1635 port new setting code to Sun C 5.8 2005/10/13
1636 * chartab.c, lisp.h (char_table_set, char_table_set_range):
1637 Return void, not Lisp_Object. Otherwise, the compiler
1638 complains about (A?B:C) where B is void and C is Lisp_Object
1639 when compiling CHAR_TABLE_SET, due to the recent change to
1640 the API of sub_char_table_set_contents.
1642 2012-08-18 Chong Yidong <cyd@gnu.org>
1644 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
1645 for the string case (Bug#3874).

1728 are compiled into code.
1729 (tset_param_alist): New setter function.
1731 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>

1766 A few more naming-convention fixes for getters and setters.
1767 * buffer.c (set_buffer_overlays_before): Move here from buffer.h,

1769 (set_buffer_overlays_after): Move here from buffer.h, and rename
1770 from buffer_overlays_set_after.

1800 The old version was confusing because it used the same name

2472 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
2473 * w32.c (init_environment): Change the default values of many
2474 environment variables in dflt_envvars[] to NULL, to avoid pushing
2475 them into environment when they were not already defined.
2476 Remove the code that deletes site-lisp subdirectories from the default
2477 value of EMACSLOADPATH, as it is no longer needed.
2478 (check_windows_init_file): Now external, not static.
2479 Use Vload_path as is, without adding anything, as this function is now
2480 called when Vload_path is already set up.
2482 * w32.h (check_windows_init_file): Add prototype.
2484 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

2528 Remove unnecessary pointer casts.
2529 * alloc.c (record_xmalloc): New function.
2530 * lisp.h (record_xmalloc): New decl.
2531 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
2532 more like a function. This is because the pointer cast is not
2533 needed. All uses changed.
2534 * print.c (print_string, print_error_message): Avoid length recalc.
2536 Improve fix for macroexp crash with debugging (Bug#12118).
2537 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
2538 ARRAY_MARK_FLAG when checking subscripts, because ASET is
2539 not supposed to be invoked from the garbage collector.

2541 (gc_aset): New function, which is like ASET but can be
2542 used in the garbage collector.

2571 with addition of handling of symlinks and support for 'lstat'.
2572 If possible, get file's attributes and security information by
2573 handle, not by name. Produce S_IFLNK bit for symlinks, when
2574 called from 'lstat'.
2575 (stat, lstat): New functions, call 'stat_worker'.
2576 (symlink, readlink, careadlinkat): Rewritten to create and resolve
2577 symlinks when the underlying filesystem supports them.
2579 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
2581 Fix macroexp crash on Windows with debugging (Bug#12118).
2582 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
2583 checking subscripts; problem introduced with the recent
2584 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
2585 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
2586 since it's used in non-static inline functions now.
2588 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
2589 Don't assume buffer size fits in 'int'. Remove unused local.

2609 * composite.c (COMPOSITE_INLINE):
2610 * dispnew.c (DISPEXTERN_INLINE):
2611 * sysdep.c (SYSTIME_INLINE):
2612 Define to EXTERN_INLINE, so that the corresponding functions
2613 are compiled into code.
2614 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
2615 (INLINE_HEADER_END): New macros.
2616 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

2636 hard-coding the path separator.
2638 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
2640 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
2641 This how ASET and AREF are supposed to work, and makes
2642 it easier to think about future improvements. See
2643 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
2644 * charset.h (set_charset_attr): New function.

3142 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

3148 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3149 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3150 not be usable in #if. This simplifies things.

3159 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3160 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3161 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3162 Adjust to changes in lisp.h and emacs.c, by using
3163 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
3164 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
3165 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
3166 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
3167 instead of gdb_valbits.
3168 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
3169 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
3170 instead of gdb_array_mark_flag.
3171 (xboolvector): Get size from $->size, not $->header.size.
3172 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
3173 (xreload, hook-run, hookpost-run): Remove.
3174 * emacs.c: Include <verify.h>.
3175 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)

3183 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these

3186 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
3187 Now enum constants, not macros, so they're visible to GDB.
3188 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
3189 more convenient now. All uses changed.
3190 (VALMASK) [USE_LSB_TAG]: Also define in this case.

3206 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
3207 than macros. This simplifies debugging in the usual case, since
3208 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
3209 and it allows expressions involving EMACS_INT casts.
3210 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
3212 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

3229 buffer_defaults and buffer_local_symbols (for sanity and safety).
3231 2012-07-24 Eli Zaretskii <eliz@gnu.org>

3264 Swap buffer text indirection counters in Fbuffer_swap_text.
3265 * buffer.c (Fbuffer_swap_text): Swap indirections too.
3266 This avoids crash reported by Christoph Scholtes at
3267 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
3269 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
3271 * nsmenu.m (Popdown_data): New struct.

3294 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
3296 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
3297 as it's limited by the amount of memory, not by INT_MAX.
3299 2012-07-21 Eli Zaretskii <eliz@gnu.org>
3301 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

3458 * keyboard.c (command_loop_1): Set it.
3459 * cmds.c (Fself_insert_command): Use it to only remove boundaries that

4044 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
4045 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4046 not functions. All uses rewritten to use the following, respectively:

4048 (add_emacs_time, sub_emacs_time): New functions.
4049 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

4075 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4076 * nsterm.m (ns_term_init):
4077 Avoid the need for strncpy, by using build_string or
4078 make_unibyte_string directly. Use dtoastr, not snprintf.
4079 * process.c (Fmake_network_process): Diagnose service names that
4080 are too long, rather than silently truncating them or creating
4081 non-null-terminated names.
4082 (Fnetwork_interface_info): Likewise, for interface names.
4083 * sysdep.c (system_process_attributes) [GNU_LINUX]:
4084 Prefer sprintf to strncat.
4085 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

4097 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
4098 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

4111 Optimize pure C strings initialization.
4112 * lisp.h (make_pure_string): Fix prototype.
4113 (build_pure_c_string): New function, defined as static inline. This
4114 provides a better opportunity to optimize away calls to strlen when
4115 the function is called with compile-time constant argument.
4116 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
4117 argument, adjust users accordingly. Use build_pure_c_string where
4119 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
4120 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
4121 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
4123 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4125 Avoid calls to strlen in miscellaneous functions.
4126 * buffer.c (init_buffer): Use precalculated len, adjust if needed.

4148 * s/gnu.h (DATA_START): Move definitions to configure.
4150 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
4151 We include usg5-4-common.h, which defines them both.
4153 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
4154 O_RDONLY already includes it).
4156 Stop ns builds setting the EMACSLOADPATH environment variable.
4157 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4158 Now it does not set EMACSLOADPATH, just returns the load-path string.
4159 * nsterm.h: Update accordingly.
4160 * lread.c [HAVE_NS]: Include nsterm.h.
4161 (init_lread) [HAVE_NS]: Use ns_load_path.

4164 2012-07-09 Glenn Morris <rgm@gnu.org>
4166 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
4167 since the included bsd-common.h does so.
4169 Stop ns builds setting the EMACSPATH environment variable.
4170 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
4171 (ns_init_paths): Do not set EMACSPATH.
4172 * nsterm.h (ns_exec_path): Add it.
4173 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
4176 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
4178 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
4180 * process.c (wait_reading_process_output): 'waitchannels' was unset
4181 when read_kbd || !NILP (wait_for_cell); fix this.
4183 Add GCC-style 'const' attribute to functions that can use it.
4184 * character.h (char_resolve_modifier_mask):
4185 * keyboard.h (make_ctrl_char):
4186 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

4195 Add decls with ATTRIBUTE_CONST.
4197 Minor improvements to make_formatted_string.
4198 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
4199 where int is good enough, as vsprintf returns an int.
4200 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
4202 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4204 Use make_formatted_string to avoid double length calculation.
4205 * lisp.h (make_formatted_string): New prototype.
4206 * alloc.c (make_formatted_string): New function.

4229 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4231 Move marker debugging code under MARKER_DEBUG.
4232 * marker.c (MARKER_DEBUG): Move marker debugging code under
4233 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4234 for bootstrap with --enable-checking (~3x slowdown reported
4235 by Juanma Barranquero <lekktu@gmail.com>).
4236 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4238 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4240 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
4241 See <http://bugs.gnu.org/11825#29>.
4243 2012-07-08 Eli Zaretskii <eliz@gnu.org>
4245 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4246 has no font, use the frame's font. (Bug#11813)
4247 (display_line): Add commentary about displaying truncation glyphs
4249 (produce_special_glyphs): Move here from term.c.
4251 * term.c (produce_special_glyphs): Move to xdisp.c.
4253 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4256 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4258 * xdisp.c (display_line): Avoid warning about implicit declaration
4261 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4263 * lisp.h: Remove empty conditional.
4265 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4267 * lread.c (load_path_check): Now static.
4269 Fix some minor --with-ns problems found by static checking.
4270 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
4271 (x_set_font) [!HAVE_X_WINDOWS]:
4272 * image.c (xpm_load_image) [HAVE_NS]:
4273 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4274 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4275 Remove unused local.
4276 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
4277 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
4278 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
4279 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
4280 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
4281 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
4282 Fix pointer signedness problem.
4283 * xfaces.c (FRAME_X_FONT_TABLE):
4284 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
4286 2012-07-07 Glenn Morris <rgm@gnu.org>
4288 * lread.c (load_path_check): New function, split from init_lread.
4289 (init_lread): Reorganize. Motivation:
4290 If EMACSLOADPATH is set, check/warn about that rather than the
4291 defaults, which we are not going to use. Hence we can remove
4292 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4293 Don't warn if site-lisp directories are missing.
4294 If not installed, start from a blank load-path, since
4295 PATH_LOADSEARCH refers to the eventual installation directories.
4297 2012-07-07 Eli Zaretskii <eliz@gnu.org>
4299 Support truncation and continuation glyphs on GUI frames, when
4300 fringes are disabled. (Bug#11832)
4301 * xdisp.c (init_iterator): Get dimensions of truncation and
4302 continuation glyphs even if on GUI frames.
4303 Adjust it->last_visible_x on GUI frames when the left or right fringes,
4304 or both, are absent.
4305 (start_display, move_it_in_display_line_to): Handle the case of a
4306 GUI frame without a fringe to display continuation or truncation
4308 (insert_left_trunc_glyphs): Support GUI frames: make sure
4309 truncation glyphs overwrite enough glyphs from the current line to
4310 have sufficient space in pixels.
4311 (display_line): Support truncation and continuation glyphs on GUI
4312 frames. If some spare pixels are left on the line after inserting
4313 the truncation glyphs, fill that space with a stretch glyph of a
4314 suitably computed width.
4316 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4317 produce_glyphs, to support GUI sessions.
4319 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4321 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4323 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4325 Do not require float-time's arg to fit in time_t (Bug#11825).
4326 This works better on hosts where time_t is unsigned, and where
4327 float-time is applied to the (negative) difference between two times.
4328 * editfns.c (decode_time_components): Last arg is now double *,
4329 not int *, and means to store all the result as a double, without
4330 worrying about whether the seconds part fits in time_t.
4331 All callers changed.
4332 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4333 All callers changed.
4334 (Ffloat_time): Do not fail merely because the specified time falls
4335 outside of time_t range.
4337 2012-07-07 Glenn Morris <rgm@gnu.org>
4339 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
4340 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

4343 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
4345 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
4346 Update dependencies.
4348 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
4350 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4352 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

4354 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
4355 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
4356 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
4357 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
4359 * xfont.c (compare_font_names): Redo to omit the need for casts.
4361 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4363 * xfns.c (Fx_change_window_property): Doc fix.
4364 * w32fns.c (Fx_change_window_property): Doc fix.
4366 * w32fns.c (Fx_window_property): Accept the same arguments as the
4367 X Windows version. Doc fix.
4368 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4370 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4371 Eli Zaretskii <eliz@gnu.org>
4373 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4374 Windows-specific code from nt/config.nt moved here.
4375 Obsolete settings removed.
4377 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4379 * process.c: Avoid unnecessary calls to gettime.
4380 (wait_reading_process_output): Don't get the time of day
4381 when gobbling data immediately and not waiting, as there's no need
4382 for it in that case. This removes a FIXME.
4384 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4386 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4387 is defined (Bug#11768).
4389 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4391 Fix marker debugging code.
4392 * marker.c (byte_char_debug_check): Do not perform the check
4393 if buffer is not multibyte.
4394 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4395 Call byte_char_debug_check with correct arguments.
4397 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4399 Compile marker debugging code only if ENABLE_CHECKING is defined.
4400 * marker.c (byte_char_debug_check, count_markers):
4401 Use only if ENABLE_CHECKING is defined.
4402 (byte_debug_flag): Remove.
4403 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4404 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4406 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4408 Avoid code repetition in marker-related functions.
4409 * marker.c (attach_marker): New function.
4410 (Fset_marker, set_marker_restricted, set_marker_both)
4411 (set_marker_restricted_both): Use it.
4412 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4413 Consistently rename charno to charpos.
4414 (marker_position): Add eassert.
4415 (marker_byte_position): Convert to eassert.

4434 * window.c (save_window_save): Likewise.
4436 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4438 Do not use Fdelete_overlay in delete_all_overlays
4439 to avoid redundant calls to unchain_overlay.
4440 * buffer.c (drop_overlay): New function.
4441 (delete_all_overlays, Fdelete_overlay): Use it.
4442 * minibuf.c (get_minibuffer): Fix comment.
4444 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4446 Port to OpenBSD 5.1 amd64.
4447 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4448 This is needed for OpenBSD, and should be harmless on all BSD systems.
4449 Also, include <sys/sysctl.h>, as it should be available on all
4450 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4451 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4452 use p_pid member, not kp_proc.pid.
4454 2012-07-06 Glenn Morris <rgm@gnu.org>
4456 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4458 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4460 More xmalloc and related cleanup.

4464 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
4465 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:

4469 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4471 Omit needless casts involving void * pointers and allocation.
4472 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4473 as the former is more robust if P's type is changed.
4474 Prefer xzalloc to xmalloc + memset 0.
4475 Simplify malloc-or-realloc to realloc.
4476 Don't worry about xmalloc returning a null pointer.
4477 Prefer xstrdup to xmalloc + strcpy.
4478 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4480 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4481 alloca of a constant.
4483 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4485 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4486 hscroll is larger than the line width. Fixes long and futile
4487 looping inside extend_face_to_end_of_line (on a TTY) producing
4488 glyphs that are not needed and thrown away.
4490 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

4502 not defined (Bug#11768).
4503 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
4504 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
4505 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
4506 followed by gtk_box_set_homogeneous (Bug#11768).
4507 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4508 (update_theme_scrollbar_width, xg_create_scroll_bar):
4509 Use gtk_scrollbar_new (Bug#11768).
4510 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
4511 (is_box_type): New function (Bug#11768).
4512 (xg_tool_item_stale_p): Call is_box_type.

4518 * xdisp.c (window_hscroll_limited): New function.
4519 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
4520 coordinates when window's hscroll is set to insanely large
4523 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
4525 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

4587 Problem reported by Troels Nielsen in
4588 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

4592 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
4593 This should be fixed in a better way; see Eli Zaretskii in
4594 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
4595 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
4597 * fileio.c (time_error_value): Rename from special_mtime.
4598 The old name's problems were noted by Eli Zaretskii in
4599 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
4601 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
4602 This variable's comment says Emacs needs at least one GDB-visible
4603 symbol of type enum pvec_type, to work around GDB problems.
4604 The symbol's value doesn't matter.
4606 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
4607 that causes compilation to fail on pre-C99 compilers.
4609 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
4611 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
4612 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
4614 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4616 * buffer.c (init_buffer_once): Fix initialization of
4617 headers for buffer_defaults and buffer_local_symbols.
4618 Reported by Juanma Barranquero <lekktu@gmail.com>.
4620 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
4622 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
4623 * lisp.h (enum pvec_type): Use fewer bits.
4624 (PSEUDOVECTOR_SIZE_BITS): New constant.
4625 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
4626 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
4627 change in pvec_type.
4628 (PSEUDOVECTOR_TYPEP): New macro.
4629 (TYPED_PSEUDOVECTORP): Use it.
4630 * fns.c (internal_equal): Adapt code to extract pvectype.

4634 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
4635 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
4636 (sweep_vectors): Use it. Use local var `total_bytes' instead of
4637 abusing vector->header.next.nbytes.
4638 (live_vector_p): Use PVEC_TYPE.
4639 (mark_object): Adapt code to extract pvectype. Use switch.
4641 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4643 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
4644 Tighten new eassert a bit.
4646 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4648 Fix compilation with --enable-gcc-warnings and -O1
4650 * doprnt.c (doprnt): Change type of tem to int, initialize
4651 to avoid compiler warning. Add eassert.
4652 * search.c (simple_search): Initialize match_byte to avoid
4653 compiler warning. Add eassert.
4655 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4657 Avoid weird behavior with large horizontal scrolls.
4658 Without this change, for example, large hscroll values would
4659 mess up Emacs's display on Fedora 15 x86, presumably due to
4660 overflows in int calculations in the display code.
4661 Also, if buffers had long lines, Emacs would freeze.
4662 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
4663 (set_window_hscroll): New function, containing the old guts of
4664 Fset_window_hscroll. Return the clipped value.
4665 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
4666 This avoids the need to check against PTRDIFF_MAX.
4668 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
4670 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4672 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
4674 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4676 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
4677 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
4678 since GCC 4.4.6 issues a bogus warning for them.
4680 Fix bugs in file timestamp newness comparisons.
4681 * fileio.c (Ffile_newer_than_file_p):
4682 * lread.c (Fload): Use full timestamp resolution of files,
4683 not just the 1-second resolution, so that files that are only
4684 slightly newer still count as newer.
4685 * fileio.c (Ffile_newer_than_file_p): Don't assume file
4686 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
4688 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
4690 * fileio.c: Improve handling of file time marker. (Bug#11852)
4691 (special_mtime): New function.
4692 (Finsert_file_contents, Fverify_visited_file_modtime):
4693 Use it to set special mtime values consistently.
4695 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
4697 * fileio.c (Finsert_file_contents): Properly handle st_mtime
4698 marker for non-existing file. (Bug#11852)
4700 2012-07-03 Glenn Morris <rgm@gnu.org>
4702 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
4703 and did not make it into globals.h).
4705 2012-07-03 Tom Tromey <tromey@redhat.com>
4707 * window.c (Fset_window_margins, Fset_window_fringes)

4741 * xterm.h: Remove EXFUN.
4743 2012-07-03 Glenn Morris <rgm@gnu.org>
4745 * lisp.h (Frandom): Make it visible to C.
4746 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
4747 buffer for invisible buffers. (Bug#1229)
4749 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4751 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
4752 values which aren't power of 2.
4753 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
4754 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
4757 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
4759 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
4761 * alloc.c (mark_object): Revert part of last patch to use `switch'.
4763 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4765 * alloc.c (allocate_vector_block): Remove redundant
4766 calls to mallopt if DOUG_LEA_MALLOC is defined.
4767 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
4768 avoid calls to mallopt if zero_vector is returned.
4770 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4772 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
4773 is enabled, avoid dereferencing NULL current_sblock if
4776 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4778 Cleanup basic buffer management.
4779 * buffer.h (struct buffer): Change layout to use generic vector
4780 marking code. Fix some comments. Change type of 'clip_changed'
4781 to bitfield. Remove unused #ifndef old.
4782 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
4783 (GET_OVERLAYS_AT): Fix indentation.
4784 (for_each_per_buffer_object_at): New macro.
4785 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

4787 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
4788 * alloc.c (allocate_buffer): Adjust to match new layout of
4789 struct buffer. Fix comment.
4790 (mark_overlay): New function.

4792 Lisp area of struct buffer.
4793 (mark_object): Use it. Adjust marking of misc objects
4794 and related comments.
4796 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
4798 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
4799 wrapper that is not needed because the wrapped code is a no-op (zero
4800 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
4801 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
4803 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
4805 * alloc.c (mark_buffer): Simplify. Remove prototype.
4806 (mark_object): Add comment. Reorganize marking of vector-like
4807 objects. Use CHECK_LIVE for all vector-like objects except buffers
4808 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
4809 Avoid redundant calls to mark_vectorlike for bool vectors.
4811 2012-06-30 Glenn Morris <rgm@gnu.org>
4813 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
4815 * epaths.in (PATH_SITELOADSEARCH): New.
4816 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
4817 This is rather than relying on --enable-locallisppath elements
4818 having "site-lisp" in their names. (Bug#10208#25, 11658)
4820 2012-06-30 Eli Zaretskii <eliz@gnu.org>
4822 * w32proc.c (sys_select): Accept and ignore one more argument.
4824 * w32.c (emacs_gnutls_pull): Call select with one more argument.
4826 * sysselect.h [DOS_NT]: Don't include sys/select.h.
4827 (pselect) [!MS_DOS]: Redirect to sys_select.
4829 * sysdep.c: Don't include dos.h and dosfns.h.
4831 * process.c (sys_select):
4832 * msdos.c (sys_select): Accept one more argument and ignore it.
4834 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
4835 adapt data types and code to that.
4838 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
4839 which clashes with the gnulib function of the same name.
4841 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
4843 * font.c (font_style_to_value, font_style_symbolic)
4844 (font_prop_validate_style): Add type checks for values in
4847 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
4849 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
4852 2012-06-29 Eli Zaretskii <eliz@gnu.org>
4854 * xdisp.c (try_window_id): Undo last change.
4856 * w32.c (getwd): Adjust commentary about startup_dir.
4857 (init_environment): Always call sys_access, even in non-MSVC
4858 builds. Don't chdir to the directory of the Emacs executable.
4859 This undoes code from 1997 which was justified by the need to
4860 "avoid conflicts when removing and renaming directories". But its
4861 downside was that every relative file name was being interpreted
4862 relative to the directory of the Emacs executable, which can never
4863 be TRT. In particular, it broke sys_access when called with
4864 relative file names.
4865 (sys_access): Map GetLastError to errno.
4867 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4869 * window.h (struct window): Change type of 'fringes_outside_margins'

4873 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
4876 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
4878 * gnutls.c (emacs_gnutls_handshake):
4879 Add QUIT to make the loop interruptible.
4881 2012-06-29 Glenn Morris <rgm@gnu.org>
4883 * charset.c (init_charset): Make lack of etc/charsets fatal.
4885 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4887 * editfns.c (region_limit): Fix type mismatch.
4889 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4891 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
4892 undefined. Convert from xassert to eassert.
4893 * nsmenu.m: Convert from xassert to eassert.
4894 * nsterm.m: Likewise.
4896 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
4898 * editfns.c (region_limit): Clip to narrowing (bug#11770).
4900 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
4902 Avoid integer overflow on scroll-left and scroll-right.
4903 * window.c (HSCROLL_MAX): New macro.
4904 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
4905 overflow when requested scroll falls outside ptrdiff_t range.
4907 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
4909 * window.h (struct window): Change type of 'hscroll',
4910 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
4911 'last_modified' and 'last_overlay_modified' to EMACS_INT.
4912 Adjust users accordingly.
4913 * xdisp.c (try_cursor_movement): Replace type check with eassert.
4914 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
4915 from EMACS_INT to ptrdiff_t.
4916 (make_window): Omit redundant initialization.
4918 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
4920 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
4922 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
4924 * window.h (struct window): Change type of 'use_time' and
4925 'sequence_number' from Lisp_Object to int.
4926 * frame.c (make_frame): Adjust users accordingly.
4927 * print.c (print_object): Likewise.
4928 * window.c (select_window, Fwindow_use_time, make_parent_window)
4929 (make_window): Likewise.
4931 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
4933 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
4934 enabled with --enable-checking=[all,glyphs] configure option.
4935 Fix GLYPH_DEBUG usage assuming that it may be undefined,
4936 adjust comments accordingly.
4937 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
4938 undefined, adjust comments accordingly.

5059 Use sprintf return value instead of invoking strlen on result.
5060 In the old days this wasn't portable, since some sprintf
5061 implementations returned char *. But they died out years ago and
5062 Emacs already assumes sprintf returns int.
5063 Similarly for float_to_string.
5064 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

5072 Use sprintf or float_to_string result to avoid need to call strlen.
5073 * data.c (Fnumber_to_string):
5074 Use make_unibyte_string, since the string must be ASCII.
5075 * lisp.h, print.c (float_to_string): Now returns int length.
5076 * term.c (produce_glyphless_glyph):
5077 Use sprintf result rather than recomputing it.
5079 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
5080 * Makefile.in (ALL_CFLAGS):

5112 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

5117 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
5118 instead of truncating it to 63 (admittedly a generous limit).

5178 * keyboard.c (kbd_buffer_get_event):
5179 * process.c (Faccept_process_output):
5180 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
5181 This improves on the previous patch, which introduced a bug
5182 when time_t is unsigned and as wide as intmax_t.
5183 See <http://bugs.gnu.org/9000#51>.

5248 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5250 Support higher-resolution time stamps (Bug#9000).
5251 The time stamps are only nanosecond-resolution at the C level,
5252 since that's the best that any real-world system supports now.
5253 But they are picosecond-resolution at the Lisp level, as that's
5254 easy, and leaves room for future OS improvements.
5256 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5259 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5260 Don't get current time unless it's needed.
5262 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5263 now provides it if it's absent.
5264 (start_atimer): Port to higher-res time stamps.
5265 Check for time stamp overflow. Don't get current time more
5266 often than is needed.
5268 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5269 Include systime.h, not time.h.
5270 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
5272 * dired.c: Include stat-time.h.
5273 (Ffile-attributes): File times now have higher resolution.
5275 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
5276 (struct image): Timestamp now has higher resolution.
5278 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5279 has at least microseconds now. All uses removed.
5280 (update_frame, update_single_window, update_window, update_frame_1)
5281 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5282 (duration_to_sec_usec): Remove; no longer needed.
5284 * editfns.c (time_overflow): Now extern.
5285 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
5286 (float-time, Fformat_time_string, Fcurrent_time_string)

5290 (decode_time_components, lisp_seconds_argument): New functions.
5291 (make_time): Now static.
5292 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
5293 Report an error if the time is invalid, rather than having the caller
5296 * fileio.c: Include <stat-time.h>
5297 (Fcopy_file): Copy higher-resolution time stamps.
5298 Prefer to set the time stamp via a file descriptor if that works.

5300 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
5301 (Fvisited_file_modtime, Fset_visited_file_modtime):
5302 Support higher-resolution time stamps.
5304 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
5306 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
5308 * image.c (prepare_image_for_display, clear_image_cache)
5309 (lookup_image): Port to higer-resolution time stamps.
5311 * keyboard.c (start_polling, bind_polling_period):
5312 Check for time stamp overflow.
5313 (read_char, kbd_buffer_get_event, timer_start_idle)
5314 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
5315 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5316 Port to higher-resolution time stamps. Do not assume time_t is signed.
5317 (decode_timer): New function. Timers are now vectors of length 9,
5318 not 8, to accommodate the picosecond component.
5319 (timer_check_2): Use it.
5321 * nsterm.m (select_timeout, timeval_subtract): Remove.
5322 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5323 as they're a bit more accurate and handle overflow better.
5324 (ns_select): Change prototype to be compatible with pselect.
5325 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5326 * nsterm.h (ns_select): Adjust prototype.
5328 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5329 us-resolution time stamps.
5330 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5332 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5334 * lisp.h (time_overflow): New decl.
5335 (wait_reading_process_output): First arg is now intmax_t, not int,
5336 to accommodate larger waits.
5338 * process.h (struct Lisp_Process.read_output_delay):
5339 Now counts nanoseconds, not microseconds.
5340 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
5342 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
5343 (wait_reading_process_output):
5344 Port to ns-resolution time stamps.
5345 (Faccept_process_output, wait_reading_process_output):
5346 Check for time stamp overflow. Do not assume time_t is signed.
5347 (select_wrapper): Remove; we now use pselect.
5348 (Fprocess_attributes): Now generates ns-resolution time stamps.
5350 * sysdep.c: Include utimens.h. Don't include utime.h
5351 or worry about struct utimbuf; gnulib does that for us now.
5352 (gettimeofday): Remove; gnulib provides a substitute.
5353 (make_timeval): New function.
5354 (set_file_times): Now sets ns-resolution time stamps.
5355 New arg FD; all uses changed.
5356 (time_from_jiffies, ltime_from_jiffies, get_up_time)
5357 (system_process_attributes):
5358 Now returns ns-resolution time stamp. All uses changed.
5359 Check for time stamp overflow.
5361 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5362 provides a substitute now.
5364 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5365 since it guarantees struct timespec.
5366 (EMACS_TIME): Now struct timespec, so that we can support
5367 ns-resolution time stamps.
5368 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5369 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5370 (EMACS_USECS): Remove.
5371 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5372 so multiply the arg by 1000 before storing it.
5373 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
5375 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
5376 Port to ns-resolution time stamps.
5377 (EMACS_TIME_NEG_P): Remove; replaced by....
5378 (EMACS_TIME_SIGN): New macro.
5379 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
5380 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
5381 (set_file_times, make_time, lisp_time_argument): Adjust signature.
5382 (make_timeval, make_lisp_time, decode_time_components): New decls.
5383 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
5384 that it mishandled time_t overflow. You can't compare by subtracting!
5385 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
5386 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
5388 * term.c: Include <sys/time.h>.
5389 (timeval_to_Time): New function, for proper overflow wraparound.
5390 (term_mouse_position, term_mouse_click): Use it.
5392 * undo.c (record_first_change): Support higher-resolution time stamps
5394 (Fprimitive_undo): Use them when restoring time stamps.
5396 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
5397 (w32_get_internal_run_time):
5398 Port to higher-resolution Emacs time stamps.
5399 (ltime): Now accepts single 64-bit integer, as that's more convenient
5402 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
5404 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
5405 for compatibility with pselect. Support ns-resolution time stamps.
5407 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
5409 * xselect.c (wait_for_property_change, x_get_foreign_selection):
5410 Check for time stamp overflow, and support ns-resolution time stamps.
5412 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
5413 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
5414 (timeval_subtract): Remove; no longer needed.
5415 (XTflash, XTring_bell, x_wait_for_event):
5416 Port to ns-resolution time stamps. Don't assume time_t is signed.
5418 2012-06-22 Chong Yidong <cyd@gnu.org>
5420 * xdisp.c (x_consider_frame_title): Revert last change.
5422 2012-06-22 Eli Zaretskii <eliz@gnu.org>
5424 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
5425 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5426 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
5427 staticidx goes up to 1597 out of 1600 = 0x640.)
5429 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
5431 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
5432 Otherwise, the umask might be mistakenly 0 while handling input signals.
5434 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
5436 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

5701 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
5702 Use an inline function on all platforms when using the union type,
5703 since this is simpler and 'static inline' can be used portably

5848 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
5849 would mishandle a string argument "Xc" if X was a multibyte

5920 bitfields where appropriate, remove unused fields.
5921 * window.h (struct window): Remove unused 'last_mark_x' and
5922 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
5923 change it's type from Lisp_Object to bitfield.
5924 Change type of 'force_start', 'optional_new_start',
5925 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
5926 fields from Lisp_Object to bitfield. Adjust users accordingly.
5928 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5930 Pacify gcc -Wdouble-precision when using Xaw.
5931 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
5932 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
5933 Use 'float' consistently, rather than 'float' in most places
5934 and 'double' in a couple of places.
5936 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5938 * xdisp.c (handle_stop): Detect whether we have overlay strings
5939 loaded by testing it->current.overlay_string_index to be
5940 non-negative, instead of checking whether n_overlay_strings is
5941 positive. (Bug#11587)
5943 2012-05-31 Chong Yidong <cyd@gnu.org>
5945 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
5947 * doc.c (Fsubstitute_command_keys): Doc fix.
5949 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5951 * search.c (search_buffer): Remove calls to
5952 r_alloc_inhibit_buffer_relocation, as it is now called by
5953 maybe_unify_char, which was the cause of relocation of buffer text
5956 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5958 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
5959 for the duration of call to load_charset, to avoid problems with
5960 callers of maybe_unify_char that access buffer text through C
5963 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
5964 decrement the inhibition flag, instead of just setting or
5967 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5969 Remove obsolete '#define static' cruft.
5970 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
5971 This #undef was "temporary" in 2000; it is no longer needed
5972 now that '#define static' has gone away.
5973 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
5974 (gray_bitmap_bits): Remove; no longer needed.
5975 All uses replaced with definiens.
5976 * xterm.c: Include "bitmaps/gray.xbm".
5978 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
5980 Clean up __executable_start, monstartup when --enable-profiling.
5981 The following changes affect the code only when profiling.
5982 * dispnew.c (__executable_start): Rename from safe_bcopy.
5983 Define only on platforms that need it.
5984 * emacs.c: Include <sys/gmon.h> when profiling.
5985 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
5986 (__executable_start): Remove decl, since lisp.h does it now.
5987 (safe_bcopy): Remove decl; no longer has that name.
5988 (main): Coalesce #if into single bit of code, for simplicity.
5989 Cast pointers to uintptr_t, since standard libraries want integers
5991 * lisp.h (__executable_start): New decl.
5993 2012-05-31 Glenn Morris <rgm@gnu.org>
5995 * image.c (Fimagemagick_types): Doc fix.

6014 * lread.c (read1): Tiny simplification.
6016 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
6018 Do not create empty overlays with the evaporate property (Bug#9642).
6019 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6020 Bug#9642, but explicitly check that the buffer the overlay would
6021 be moved to is live and rearrange lines to make sure that errors
6022 will not put the overlay in an inconsistent state.
6023 (Fdelete_overlay): Cosmetics.
6025 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6027 * w32term.c (my_bring_window_to_top): New function.
6028 (x_raise_frame): Use handle returned by DeferWindowPos, which
6029 could be different from the original one.

6033 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6034 by calling BringWindowToTop.
6036 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6037 (WM_EMACS_END): Increase by one.
6039 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6041 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6042 This avoids undefined behavior that might cause the eassert
6043 to not catch an out-of-range value.
6045 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6047 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
6048 Update dependencies.
6050 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6052 * bidi.c (bidi_mirror_char): Fix last change.
6054 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

6057 when referring to sectname field in printf format.
6059 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
6061 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6062 Only r_alloc_inhibit_buffer_relocation needed to be added;
6063 the others were already declared.
6065 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6066 before checking whether it's out of range. Put the check inside
6068 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6070 2012-05-27 Ken Brown <kbrown@cornell.edu>
6072 * callproc.c (Fcall_process): Restore a line that was accidentally
6073 commented out in the 2011-02-13 change (bug#11547).
6075 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6077 * lisp.h [REL_ALLOC]: Add prototypes for external functions
6078 defined on ralloc.c.
6080 * buffer.c [REL_ALLOC]: Remove prototypes of
6081 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
6082 they are now on lisp.h.
6084 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6086 * search.c (search_buffer): Use it to inhibit relocation of buffer
6087 text while re_search_2 is doing its job, because re_search_2 is
6088 passed C pointers to buffer text. (Bug#11519)
6090 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6093 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6094 state after an additional call to move_it_in_display_line_to, keep
6095 the values of it->max_ascent and it->max_descent found for the
6097 (pos_visible_p): Revert the comparison against bottom_y to what it
6098 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
6101 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6103 Fix coding-related core dumps with gcc -ftrapv.
6104 The code was computing A - B, where A and B are pointers, and B is
6105 random garbage. This can lead to core dumps on platforms that
6106 have special pointer registers, and it also leads to core dumps on
6107 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6108 A - B only when B is initialized properly.
6109 * coding.c (coding_set_source, coding_set_destination): Return void.
6110 (coding_change_source, coding_change_destinations): New functions,
6111 with the old behaviors of coding_set_source and coding_set_destination.
6112 All callers that need an offset changed to use these new functions.
6114 2012-05-26 Glenn Morris <rgm@gnu.org>
6116 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
6118 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6120 Extend mouse support on W32 text-mode console.
6121 * xdisp.c (draw_row_with_mouse_face):
6122 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6124 * w32console.c: Include window.h.
6125 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6127 (initialize_w32_display): Initialize mouse-highlight data.
6129 * w32inevt.c: Include termchar.h and window.h.
6130 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6131 moves, call note_mouse_highlight. If help_echo changed, call
6132 gen_help_event to produce help-echo message in the echo area.
6133 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6136 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6138 * lread.c (read1): Simplify slightly to avoid an overflow warning
6139 with GCC 4.7.0 on x86-64.
6141 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6143 * bidi.c (bidi_mirror_char): Revert last change: an int is
6144 definitely wide enough here.
6146 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
6148 Fix integer width and related bugs (Bug#9874).
6149 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
6150 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
6151 (string_bytes, check_sblock, allocate_string_data):

6154 (make_string_from_bytes, make_specified_string)
6155 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
6156 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
6158 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6159 (allocate_pseudovector):
6160 Use int, not EMACS_INT, where int is wide enough.
6161 (inhibit_garbage_collection, Fgarbage_collect):
6162 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6163 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
6164 int might not be wide enough.
6165 (bidi_cache_search, bidi_cache_find, bidi_init_it)
6166 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6167 (bidi_at_paragraph_end, bidi_find_paragraph_start)
6168 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
6169 (bidi_level_of_next_char, bidi_move_to_visually_next):
6170 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6171 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
6172 (Fkill_buffer, Fset_buffer_major_mode)
6173 (advance_to_char_boundary, Fbuffer_swap_text)
6174 (Fset_buffer_multibyte, overlays_at, overlays_in)
6175 (overlay_touches_p, struct sortvec, record_overlay_string)
6176 (overlay_strings, recenter_overlay_lists)
6177 (adjust_overlays_for_insert, adjust_overlays_for_delete)
6178 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
6179 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
6180 (Foverlay_recenter, last_overlay_modification_hooks_used)
6181 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6182 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6183 (validate_region): Omit unnecessary test for b <= e,
6184 since that's guaranteed by the previous test.
6185 (adjust_overlays_for_delete): Avoid pos + length overflow.
6186 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6187 (report_overlay_modification):
6188 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6189 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
6190 Omit pointer cast, which isn't needed anyway, and doesn't work
6191 after the EMACS_INT -> ptrdiff_t change.
6192 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
6193 * buffer.h: Adjust decls to match defn changes elsewhere.

6196 Use EMACS_INT, not int, where int might not be wide enough.
6197 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
6198 not int, to avoid needless 32-bit limit on 64-bit hosts.
6199 (exec_byte_code): Use tighter memory-full test, one that checks
6200 for alloca overflow. Don't compute the address of the object just
6201 before an array, as that's not portable. Use EMACS_INT, not
6202 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
6203 * callint.c (Fcall_interactively):
6204 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6205 * callproc.c (call_process_kill, Fcall_process):
6206 Don't assume pid_t fits into an Emacs fixnum.

6209 (call_process_cleanup, Fcall_process, delete_temp_file)
6210 (Fcall_process_region):
6211 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6212 (Fcall_process): Simplify handling of volatile integers.
6213 Use int, not EMACS_INT, where int will do.
6214 * casefiddle.c (casify_object, casify_region, operate_on_word)
6215 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
6216 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6217 (casify_object): Avoid integer overflow when overallocating buffer.
6218 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
6219 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
6220 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
6221 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6222 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6223 integers are now checked earlier. All uses replaced with XINT.
6225 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6226 For CCL_MapSingle, check that content and value are in int range.
6227 (ccl_driver, Fregister_code_conversion_map):
6228 Check that Vcode_version_map_vector is a vector.
6229 (resolve_symbol_ccl_program): Check that vector header is in range.
6230 Always copy the vector, so that we can check its contents reliably
6231 now rather than having to recheck each instruction as it's being
6232 executed. Check that vector words fit in 'int'.
6233 (ccl_get_compiled_code, Fregister_ccl_program)
6234 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6235 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
6236 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
6237 contents are in range.
6238 (Fccl_execute_on_string): Check that status is in range.
6239 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
6240 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
6241 Accept and return EMACS_INT, not int, because callers can pass values
6243 (c_string_width, strwidth, lisp_string_width, chars_in_text)
6244 (multibyte_chars_in_text, parse_str_as_multibyte)
6245 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
6246 (str_as_unibyte, str_to_unibyte, string_count_byte8)
6247 (string_escape_byte8, Fget_byte):
6248 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6249 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
6250 avoid mishandling large integers.
6251 * character.h: Adjust decls to match defn changes elsewhere.
6252 * charset.c (load_charset_map_from_file, find_charsets_in_text)
6253 (Ffind_charset_region):
6254 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6255 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
6256 (load_charset_map_from_vector, Fdefine_charset_internal):
6257 Don't assume fixnum fits in int.
6258 (load_charset_map_from_vector, Fmap_charset_chars):
6259 Remove now-unnecessary CHECK_NATNUMs.
6260 (Fdefine_charset_internal): Check ranges here, more carefully.
6261 Don't rely on undefined behavior with signed left shift overflow.
6262 Don't assume unsigned int fits into fixnum, or that fixnum fits
6263 into unsigned int. Don't require max_code to be a valid fixnum;
6264 that's not true for gb10830 4-byte on a 32-bit host. Allow
6265 invalid_code to be a cons, for the same reason. Require code_offset
6266 to be a character. Avoid int overflow if max_char is close
6268 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
6269 this is intended anyway and avoids some undefined behavior.
6270 (load_charset_map): Pass unsigned, not int, as 2nd arg of
6271 INDEX_TO_CODE_POINT, as that's what it expects.
6272 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
6273 * charset.h (DECODE_CHAR): Return int, not unsigned;
6274 this is what was intended anyway, and it avoids undefined behavior.
6275 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
6276 integer-overflow issues.
6277 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
6278 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
6279 where the argument is EMACS_INT, and this behavior is not intended.
6280 * chartab.c (Fmake_char_table, Fset_char_table_range)
6281 (uniprop_get_decoder, uniprop_get_encoder):
6282 Don't assume fixnum fits in int.
6283 * cmds.c (move_point): New function, that does the gist of
6284 Fforward_char and Fbackward_char, but does so while checking
6285 for integer overflow more accurately.
6286 (Fforward_char, Fbackward_char): Use it.
6287 (Fforward_line, Fend_of_line, internal_self_insert)
6288 (internal_self_insert):
6289 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6290 Fix a FIXME, by checking for integer overflow when calculating
6291 target_clm and actual_clm.

6321 (Funencodable_char_position, Fcheck_coding_systems_region)
6322 (get_translation, handle_composition_annotation, consume_chars):
6323 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6324 (consume_chars): Rewrite to not calculate an address outside buffer.
6325 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
6326 Don't access memory outside of the args array.
6327 (Fdefine_coding_system_internal): Check for charset-id overflow.
6328 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
6329 result of ENCODE_CHAR.
6330 * coding.h: Adjust decls to match defn changes elsewhere.
6331 (struct coding_system):

7053 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
7055 2012-05-17 Juri Linkov <juri@jurta.org>
7057 * search.c (Fword_search_regexp, Fword_search_backward)
7058 (Fword_search_forward, Fword_search_backward_lax)
7059 (Fword_search_forward_lax): Move functions to isearch.el
7060 (bug#10145, bug#11381).
7062 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
7064 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
7066 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
7068 * lread.c (init_obarray): Declare Qt and Qnil as special.
7070 2012-05-14 Glenn Morris <rgm@gnu.org>
7072 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
7073 Put "libexec" before "bin", for the sake of init_callproc_1.
7075 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7077 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
7079 * unexaix.c: Port to more-recent AIX compilers.
7080 (report_error, report_error_1, make_hdr, copy_sym)
7081 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
7082 Make arguments const char *, not char *, to avoid violations of C
7083 standard and to fix some AIX warnings reported by Gilles Pion.
7085 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7087 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
7088 already have overlays loaded.
7089 (handle_single_display_spec): Before returning without displaying
7090 fringe bitmap, synchronize the bidi iterator with the main display
7091 iterator, by calling iterate_out_of_display_property.
7092 (iterate_out_of_display_property): Detect buffer iteration by
7093 testing that it->string is a Lisp string.
7094 (get_next_display_element): When the current object is exhausted,
7095 and there's something on it->stack, call set_iterator_to_next to
7096 proceed with what's on the stack, instead of returning zero.
7097 (set_iterator_to_next): If called at the end of a Lisp string,
7098 proceed to consider_string_end without incrementing string
7099 position. Don't increment display vector index past the end of
7100 the display vector. (Bug#11417)
7101 (pos_visible_p): Don't report a position visible when move_it_to
7102 stopped at the last line of window, which happens to be scanned
7103 backwards by the bidi iteration. (Bug#11464)
7105 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7107 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7108 and right-margin display specs even if the spec is invalid or we
7109 are on a TTY, and thus unable to display on the fringes.
7110 That's because the text with the property will not be displayed anyway,
7111 so we need to signal to the caller that this is a "replacing"
7112 display spec. This fixes display when the spec is invalid or we
7115 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7117 * unexaix.c (make_hdr): Fix typo in prototype.
7118 This bug broke the build on AIX. Problem reported by Gilles Pion.
7120 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
7122 * keyboard.c (kbd_buffer_get_event): Read special events also in
7123 batch mode. (Bug#11415)
7125 2012-05-12 Glenn Morris <rgm@gnu.org>
7127 * ns.mk: Update for ns_appbindir no longer having trailing "/".
7129 2012-05-12 Eli Zaretskii <eliz@gnu.org>
7131 * lisp.mk (lisp): Add newcomment.elc.
7133 2012-05-12 Glenn Morris <rgm@gnu.org>
7135 * Makefile.in (MKDIR_P): New, set by configure.
7136 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
7138 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
7140 Remove unused function hourglass_started.
7141 * dispextern.h (hourglass_started):
7142 * w32fns.c (hourglass_started):
7143 * xdisp.c (hourglass_started): Remove.
7145 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7147 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7148 Update dependencies.
7150 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7152 * xgselect.c (xg_select): Put maxfds+1 into a var.
7153 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
7155 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7157 2012-05-10 Dave Abrahams <dave@boostpro.com>
7159 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7160 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7162 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7164 * dbusbind.c (xd_registered_buses): New internal Lisp object.
7165 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7166 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7167 Initialize xd_registered_buses.
7169 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7171 Untag more efficiently if USE_LSB_TAG.
7172 This is based on a proposal by YAMAMOTO Mitsuharu in
7173 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7174 For an admittedly artificial (nth 8000 longlist) benchmark on
7175 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7176 Emacs's overall text size by 1%.
7177 * lisp.h (XUNTAG): New macro.
7178 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7179 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7180 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7181 * eval.c (Fautoload):
7182 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7183 * frame.h (XFRAME): Use XUNTAG.
7185 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7186 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7187 Remove unportable assumptions about print widths of types like
7189 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7190 intptr_t when converting between pointer and integer, to avoid GCC
7191 warnings about wrong width.
7193 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7195 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7196 stack for each reader_thread, instead of defaulting to 8MB
7197 determined by the linker. This avoids failures in creating
7198 subprocesses on Windows 7, see the discussion in this thread:
7199 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7201 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7203 Fix up display of the *Minibuf-0* buffer in the mini window.
7204 * keyboard.c (read_char): Don't clear the echo area if there's no
7206 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7207 contents of *Minibuf-0*) if there's no message displayed in its stead.
7209 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7211 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7214 2012-05-06 Chong Yidong <cyd@gnu.org>
7216 * lisp.mk (lisp): Update.
7218 2012-05-05 Jim Meyering <meyering@redhat.com>
7220 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7222 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7224 * data.c (PUT_ERROR): New macro.
7225 (syms_of_data): Use it. Add new error type `user-error'.
7226 * undo.c (user_error): New function.
7227 (Fprimitive_undo): Use it.
7228 * print.c (print_error_message): Adjust print style for `user-error'.
7229 * keyboard.c (user_error): New function.
7230 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7232 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7234 Do not limit current-time-string to years 1000..9999.
7235 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7236 (Fcurrent_time_string): Support any year that is supported by the
7237 underlying localtime representation. Don't use asctime, as it
7238 has undefined behavior for years outside the range -999..9999.
7240 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7242 Fix race conditions involving setenv, gmtime, localtime, asctime.
7243 Without this fix, interrupts could mess up code that uses these
7244 nonreentrant functions, since setting TZ invalidates existing
7245 tm_zone or tzname values, and since most of these functions return
7246 pointers to static storage.
7247 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7248 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7249 Grow the critical sections to include not just invoking
7250 localtime/gmtime, but also accessing these functions' results
7251 including their tm_zone values if any, and any related TZ setting.
7252 (format_time_string): Last arg is now struct tm *, not struct tm **,
7253 so that the struct tm is saved in the critical section.
7254 All callers changed. Simplify allocation of initial buffer, partly
7255 motivated by the fact that memory allocation needs to be outside
7256 the critical section.
7258 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7260 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7261 with RESET_INTERVAL.
7263 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7264 Remove duplicated buffer name initialization.
7266 2012-05-02 Jim Meyering <jim@meyering.net>
7268 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7270 * xfns.c (x_window): Use xstrdup (Bug#11375).
7272 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7274 * xdisp.c (pos_visible_p): If already at a newline from the
7275 display string before the 'while' loop, don't walk back the glyphs
7276 from it3.glyph_row. Solves assertion violation when the display
7277 string begins with a newline (egg.el). (Bug#11367)
7279 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7281 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7284 2012-05-01 Glenn Morris <rgm@gnu.org>
7286 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7287 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7288 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7289 All were removed before 23.1.
7291 * dispnew.c: Remove HAVE_LIBNCURSES test;
7292 it is always true on relevant platforms.
7294 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7295 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7297 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
7299 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
7301 * .gdbinit (xpr): Remove checks for no longer existing misc types.
7302 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
7305 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
7307 Do not avoid creating empty evaporating overlays (Bug#9642).
7308 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7309 That is, do not delete an evaporating overlay if it becomes
7310 empty after its bounds are adjusted to fit within its buffer.
7311 This fix caused other problems, and I'm reverting it until we get
7312 to the bottom of them.
7314 2012-04-27 Chong Yidong <cyd@gnu.org>
7316 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7318 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7320 * xdisp.c (pos_visible_p): If the window start position is beyond
7321 ZV, start the display from buffer beginning. Prevents assertion
7322 violation in init_iterator when the minibuffer window is scrolled
7325 * window.c (window_scroll_pixel_based): Likewise.
7327 2012-04-27 Chong Yidong <cyd@gnu.org>
7329 * keymap.c (where_is_internal): Doc fix (Bug#10872).
7331 2012-04-27 Glenn Morris <rgm@gnu.org>
7333 * fileio.c (Fcopy_file, Fset_file_selinux_context):
7334 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
7336 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7338 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
7339 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
7341 2012-04-26 Eli Zaretskii <eliz@gnu.org>
7343 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7344 display element, check also the underlying string or buffer
7345 character. (Bug#11341)
7347 * w32menu.c: Include w32heap.h.
7348 (add_menu_item): If the call to AppendMenuW (via
7349 unicode_append_menu) fails, disable Unicode menus only if we are
7350 running on Windows 9X/Me.
7352 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7354 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
7355 (xgetint): Add missing shift for LSB tags.
7357 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7359 * keyboard.c (read_char): Don't wipe echo area for select window
7360 events: These might get delayed via `mouse-autoselect-window'
7363 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
7365 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
7366 manipulation of :loaded-from data.
7368 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
7370 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
7371 now a cons (bug#11311).
7373 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7375 Do not create empty overlays with the evaporate property (Bug#9642).
7376 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7377 if it becomes empty after its bounds are adjusted to fit within
7378 its buffer. Without this fix, in a nonempty buffer (let ((o
7379 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7380 yields an empty overlay that has the evaporate property, which is
7381 not supposed to happen.
7383 Fix minor GTK3 problems found by static checking.
7384 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7385 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7386 (struct _EmacsFixedClass, emacs_fixed_get_type):
7387 Move decls here from emacsgtkfixed.h, since they needn't be public.
7388 (emacs_fixed_get_type): Now static.
7389 (emacs_fixed_class_init): Omit unused local.
7390 (emacs_fixed_child_type): Remove; unused.

7393 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
7394 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
7395 (EMACS_FIXED_GET_CLASS): Remove; unused.
7396 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
7398 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
7399 Problem reported by Juanma Barranquero for Windows -Wunused-function.
7401 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7403 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
7404 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
7405 (__malloc_size_t, __malloc_ptrdiff_t):
7406 Remove. All uses removed, replaced by the definiens if needed,
7407 since we can assume C89 or better now.
7408 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
7409 (protect_malloc_state, align, get_contiguous_space)
7410 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

7416 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
7417 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
7418 Define using prototypes, not old style.
7419 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
7420 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
7421 (align): Don't assume that signed integer overflow wraps around.
7422 Omit unused local var.
7423 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
7424 (_free_internal_nolock, memalign, mallochook, reallochook):
7425 Omit no-longer-needed casts.
7426 (valloc): Use getpagesize, not __getpagesize.
7427 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
7428 (struct hdr): The 'magic' member is now size_t, not unsigned long.
7430 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
7432 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
7434 Move functions from C to Lisp. Make non-blocking method calls
7435 the default. Implement further D-Bus standard interfaces.
7437 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
7438 (QCdbus_request_name_allow_replacement)
7439 (QCdbus_request_name_replace_existing)

7477 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7479 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
7480 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
7481 Do not assume ptrdiff_t is the same width as 'int'.
7483 * alloc.c: Handle unusual debugging option combinations.
7484 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
7485 since the two debugging options are incompatible.
7486 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7488 (mem_init, mem_insert, mem_insert_fixup):
7489 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
7490 (NEED_MEM_INSERT): Remove; no longer needed.
7492 2012-04-22 Leo Liu <sdl.web@gmail.com>
7494 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
7496 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7498 * sysdep.c [__FreeBSD__]: Minor cleanups.
7499 (list_system_processes, system_process_attributes) [__FreeBSD__]:
7500 Use Emacs indenting style more consistently. Avoid some casts.
7501 Use 'double' consistently rather than mixing 'float' and 'double'.
7503 2012-04-21 Eduard Wiebe <usenet@pusto.de>
7505 * sysdep.c (list_system_processes, system_process_attributes):

7519 * print.c (print_preprocess): Only check print_depth if print-circle
7521 (print_object): Check for cycles even when print-circle is nil and
7522 print-gensym is t, but only check print_depth if print-circle is nil.
7524 2012-04-20 Chong Yidong <cyd@gnu.org>
7526 * process.c (wait_reading_process_output): If EIO occurs on a pty,

7542 farther than the first row after the header line, if any.
7543 Don't consider the header-line row as "partially visible", even if
7544 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
7546 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

7581 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
7582 New extern decls, to avoid calling undeclared functions.
7583 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
7584 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
7585 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

7587 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
7588 Remove one incorrect comment and fix another.

7602 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
7603 Remove decls. This fixes an "It stinks!".
7605 * alloc.c (which_symbols): Fix alignment issue / type clash.
7607 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
7609 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

7622 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
7623 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
7624 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
7625 * s/netbsd.h, s/sol2-6.h:
7626 Remove definition of GC_MARK_STACK, since the default now works.
7627 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
7628 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
7629 no longer the default.
7630 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
7632 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
7634 * lread.c (lisp_file_lexically_bound_p):

7655 2012-04-11 Daniel Colascione <dancol@dancol.org>
7657 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
7658 against is gone. It's better to use vfork now so that when Cygwin
7659 gains a new, working vfork, we use it automatically (bug#10398).
7661 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

7679 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
7681 * w32.c (w32_delayed_load): Record the full path of the library
7682 being loaded (bug#10424).
7684 2012-04-09 Glenn Morris <rgm@gnu.org>
7686 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
7687 not just in the obarray, before snarfing them. (Bug#11036)
7689 * Makefile.in ($(leimdir)/leim-list.el):
7690 Pass EMACS rather than BUILT_EMACS.

7699 Add convenience `GNUTLS_LOG2i' macro.
7701 * gnutls.c (gnutls_log_function2i): Convenience log function.
7702 (emacs_gnutls_read): Use new log functions,
7703 `gnutls_handshakes_tried' process member, and

7714 * minibuf.c (Fread_variable): Callers changed.
7716 2012-04-09 Eli Zaretskii <eliz@gnu.org>
7718 * xdisp.c (set_cursor_from_row): If the display string appears in
7719 the buffer at position that is closer to point than the position
7720 after the display string, display the cursor on the first glyph of
7721 the display string. Fixes cursor display when a 'display' text
7722 property immediately follows invisible text. (Bug#11094)
7724 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
7726 composite.c: use 'double' consistently
7727 * composite.c (get_composition_id): Use 'double' consistently
7728 instead of converting 'float' to 'double' and vice versa; this is
7729 easier to understand and avoids a GCC warning.
7731 2012-04-09 Glenn Morris <rgm@gnu.org>
7733 * Makefile.in: Generate leim-list with bootstrap-emacs, in
7734 preparation for dumping it with emacs. (Bug#4789)

7756 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
7757 (mark_memory): Mark Lisp_Objects only if pointers might hide in
7758 objects, as mark_maybe_pointer will catch them otherwise.
7759 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
7760 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
7762 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
7764 Fix typo that broke non-Windows builds.
7765 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

7776 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
7777 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
7778 [!WINDOWSNT]: New macros.
7779 (init_libxml2_functions, libxml2_loaded_p): New functions.
7780 (parse_region): Call fn_xmlCheckVersion instead of using the macro
7781 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
7782 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
7783 Calls xmlCleanupParser only if libxml2 was loaded (or statically
7785 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
7786 Call init_libxml2_functions before calling libxml2 functions.
7787 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
7789 * emacs.c: Don't include libxml/parser.h.
7790 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
7791 xmlCleanupParser directly.
7793 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
7795 2012-04-07 Eli Zaretskii <eliz@gnu.org>
7797 * indent.c (Fvertical_motion): If there is a display string at
7798 point, use it.vpos to compute how many lines to backtrack after

7803 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
7804 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
7805 about subtle differences between FETCH_CHAR* and STRING_CHAR*
7806 macros related to unification of CJK characters. For the details,
7807 see the discussion following the message here:
7808 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
7810 2012-04-04 Chong Yidong <cyd@gnu.org>
7812 * keyboard.c (Vdelayed_warnings_list): Doc fix.
7814 2012-04-01 Eli Zaretskii <eliz@gnu.org>
7816 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

7824 2012-03-31 Eli Zaretskii <eliz@gnu.org>
7826 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
7827 position we get to after a call to move_it_to fails the
7828 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
7829 only if we wind up in a string from display property. (Bug#11063)
7831 * window.c (Fdelete_other_windows_internal): Invalidate the row
7832 and column information about mouse highlight, so that redisplay
7833 restores it after reallocating the glyph matrices. (Bug#7464)
7835 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
7836 string comes from a `display' text property, use the buffer
7837 position of that property as if we actually saw that position in
7839 (move_it_by_lines): Remove the assertion that
7840 "it->current_x == 0 && it->hpos == 0" which can be legitimately
7841 violated when there's a before-string at the beginning of a line.
7844 2012-03-30 Eli Zaretskii <eliz@gnu.org>
7846 * xdisp.c (append_space_for_newline): If the default face was
7847 remapped, use the remapped face for the appended newline.
7848 (extend_face_to_end_of_line): Use the remapped default face for
7849 extending the face to the end of the line.
7850 (display_line): Call extend_face_to_end_of_line when the default
7851 face was remapped. (Bug#11068)

7877 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
7879 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
7881 2012-03-25 Kenichi Handa <handa@m17n.org>
7883 * dispextern.h (struct glyph): Change the bit length of
7884 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
7886 2012-03-24 Eli Zaretskii <eliz@gnu.org>
7888 * s/ms-w32.h (tzname): Include time.h before redirecting to
7889 _tzname. Fixes the MSVC build. (Bug#9960)

7893 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
7896 * xterm.c (XTread_socket): Only modify handling_signal if
7897 !SYNC_INPUT. (Bug#11080)
7899 2012-03-23 Eli Zaretskii <eliz@gnu.org>
7901 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
7902 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
7903 when fetching a multibyte character consumes more bytes than
7904 CHAR_BYTES returns, due to unification of CJK characters in
7905 string_char. (Bug#11073)
7907 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
7909 * process.c (wait_reading_process_output): Handle pty disconnect
7910 by refraining from sending oneself a SIGCHLD (bug#10933).

7921 2012-03-21 Chong Yidong <cyd@gnu.org>
7923 * xfaces.c (Vface_remapping_alist): Doc fix.
7925 2012-03-20 Eli Zaretskii <eliz@gnu.org>
7927 * w32proc.c (Fw32_set_console_codepage)
7928 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

7939 it fit in a valid range (Bug#11003).
7941 2012-03-18 Eli Zaretskii <eliz@gnu.org>
7943 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
7944 that is not from display property, accept the row as a "cursor
7945 row" if one of the string's character has a non-nil `cursor'
7946 property. Fixes cursor positioning when there are newlines in
7947 overlay strings, e.g. in icomplete.el. (Bug#11035)
7949 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
7951 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

7955 * eval.c (inhibit_lisp_code): Rename from
7956 inhibit_window_configuration_change_hook; move from window.c.
7958 * xfns.c (unwind_create_frame_1, Fx_create_frame):
7959 * window.c (run_window_configuration_change_hook)
7960 (syms_of_window): Callers changed.
7962 2012-03-11 Chong Yidong <cyd@gnu.org>
7964 * keymap.c (Fkey_description): Doc fix (Bug#9700).
7966 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
7968 2012-03-10 Chong Yidong <cyd@gnu.org>
7970 * frame.c (other_visible_frames): Don't assume the selected frame
7971 is visible (Bug#10955).
7973 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
7975 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
7977 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
7979 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
7980 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
7983 2012-03-03 Glenn Morris <rgm@gnu.org>

7990 position past the first glyph_row that ends at ZV. (Bug#10902)
7991 (redisplay_window, next_element_from_string): Fix typos in
7993 (redisplay_window): Pass to move_it_vertically the margin in
7994 pixels, not in screen lines.
7996 2012-03-02 Glenn Morris <rgm@gnu.org>
7998 * buffer.c (buffer-list-update-hook): Doc fix.
8000 2012-02-29 Eli Zaretskii <eliz@gnu.org>

8003 push_it before setting up the iterator for the first overlay
8004 string, even if we have an empty string loaded.
8005 (next_overlay_string): If there's an empty string on the iterator
8006 stack, pop the stack. (Bug#10903)
8008 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8010 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8011 Suggested by Stefan Monnier in
8012 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8013 * alloc.c (widen_to_Lisp_Object): New static function.
8014 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8015 and widening them to Lisp_Objects. This would work even if
8016 USE_LSB_TAG is defined and wide integers are used, which might
8017 happen in a future version of Emacs.
8019 2012-02-25 Chong Yidong <cyd@gnu.org>
8021 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

8025 (x_clipboard_manager_save_all): Print an informative message
8026 before saving to clipboard manager.

8035 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
8036 call when setting menu-bar-lines and tool-bar-lines parameters.
8037 (unwind_create_frame_1): New helper function.
8039 * window.c (inhibit_window_configuration_change_hook): New var.
8040 (run_window_configuration_change_hook): Obey it.
8041 (syms_of_window): Initialize it.
8043 2012-02-22 Chong Yidong <cyd@gnu.org>
8045 * xterm.c (x_draw_image_relief): Add missing type check for

8058 when computing $valmask.
8060 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8061 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8062 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8063 It's useless in that case, and it can cause problems on hosts
8064 that allocate halves of EMACS_INT values separately.
8065 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8066 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8067 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8068 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8069 it avoids undefined behavior on hosts where shifting right by more
8070 than the word width has undefined behavior.
8072 2012-02-19 Chong Yidong <cyd@gnu.org>
8074 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
8075 (Funhandled_file_name_directory, Ffile_name_as_directory)

8094 2012-02-15 Chong Yidong <cyd@gnu.org>
8096 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

8112 2012-02-12 Chong Yidong <cyd@gnu.org>
8114 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
8115 as that creates a dangerous corner case.
8117 * window.c (Fdelete_window_internal): Invalidate the mouse
8118 highlight (Bug#9904).
8120 2012-02-12 Glenn Morris <rgm@gnu.org>

8150 2012-02-07 Chong Yidong <cyd@gnu.org>
8152 * buffer.c (Fbuffer_local_variables)
8153 (buffer_lisp_local_variables): Handle unbound vars correctly;
8154 don't let Qunbound leak into Lisp.
8156 2012-02-07 Glenn Morris <rgm@gnu.org>
8158 * image.c (Fimagemagick_types): Doc fix.
8160 * image.c (imagemagick-render-type): Change it from a lisp object

8195 Handle overflow when computing char display width (Bug#9496).
8196 * character.c (char_width): Return EMACS_INT, not int.
8197 (char_width, c_string_width): Check for overflow when
8198 computing the width; this is possible now that individual
8199 characters can have unbounded width. Problem introduced
8200 by merge from Emacs 23 on 2012-01-19.
8202 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

8342 (Fmake_directory_internal): Use it.

8872 behave as if the cursor position were at the window margin.
8874 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
8875 and the cursor position is out of bounds, behave as if the cursor

8906 * dispnew.c (verify_row_hash): Call row_hash for computing the
8907 hash code of a row, instead of duplicating code from xdisp.c.
8909 * dispextern.h (row_hash): Add prototype.
8911 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

9017 The trivial performance wins aren't worth the portability hassles; see
9018 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
9020 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

9068 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
9069 This is also needed for porting to any host where GC_MARK_STACK is
9070 not GC_MAKE_GCPROS_NOOPS.

9094 (window_box_width, window_box_left, window_box_left_offset)
9095 (window_box_right, window_box_right_offset): Declare extern.
9096 Otherwise, these inline functions do not conform to C99 and
9097 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
9098 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
9099 * intervals.c (adjust_intervals_for_insertion)
9100 (adjust_intervals_for_deletion): Now extern, because otherwise the
9101 extern inline functions 'offset_intervals' couldn't refer to it.
9102 (static_offset_intervals): Remove.
9103 (offset_intervals): Rewrite using the old contents of
9104 static_offset_intervals. The old version didn't conform to C99
9105 because an extern inline function contained a reference to an
9106 identifier with static linkage.

9418 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
9419 * editfns.c: Rewrite current-time-zone so that it invokes
9420 the equivalent of (format-time-string "%Z") to get the time zone name.
9421 This fixes a bug when the time zone name contains characters that
9422 need converting from the system time locale to Emacs internal format.
9423 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9424 that patch fixed format-time-string to do the conversion, but
9425 I forgot to fix current-time-zone.
9426 (format_time_string): New function, containing most of
9427 what Fformat_time_string used to contain.

9435 * systime.h (tzname, timezone): Remove no-longer-used declarations.

9439 * xdisp.c (start_display): If the character at POS is displayed
9440 via a display vector, reset IT->current.dpvec_index to zero.
9441 (try_window_reusing_current_matrix): If a line ends in a display
9442 vector or the next line starts in a display vector, continue
9443 redrawing the window even though the character position of
9444 start_row was reached.
9447 2011-10-18 Chong Yidong <cyd@gnu.org>
9449 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9450 with nobreak-char-display too.
9452 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9454 Fix part 3 of bug#9771.
9455 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9456 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9457 non-neutral characters if the current character is a paragraph
9458 separator (a.k.a. Newline). This avoids running the same
9459 expensive loop twice, once when we consume the preceding newline
9460 and the other time when the line actually needs to be displayed.
9461 Avoid the loop when we see neutrals on the base embedding level
9462 following a character whose directionality is the same as the
9463 paragraph's. This avoids running the expensive loop when a line
9464 ends in a long sequence of neutrals, like control characters.
9465 Add assertion against STRONG_AL type. Slightly rearrange code
9466 that determines the type of a neutral given the first non-neutral
9468 (bidi_level_of_next_char): Set next_en_pos to zero when
9469 invalidating its info.
9471 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9473 * xdisp.c (push_display_prop): Determine whether to record string
9474 or buffer position by IT->string, not by IT->method. Allow
9475 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9476 (move_it_vertically_backward): Don't look for character position
9477 immediately after the newline when in a continuation line.
9480 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9482 * window.c (coordinates_in_window): Rewrite and delabelize
9483 vertical border check. (Bug#5357) (Bug#9618)
9485 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9487 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9488 errors in XSetWindowBorder (bug#9310).
9490 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9492 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9493 avoid crash when xmalloc overrun checking is enabled.
9495 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9497 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9498 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9499 cursor motion with <left> and <right> arrow keys.
9501 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9502 some callers set that themselves.
9504 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9506 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9507 display string and the previous row comes from the same string and
9508 is empty. (Bug#9739) (Bug#9738)
9510 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9512 * doc.c (get_doc_string): Encode file name (bug#9735).
9514 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9516 * bidi.c (bidi_level_of_next_char):
9517 * xdisp.c (get_visually_first_element): Remove old incorrect
9518 comments regarding the Unicode Line Separator character.
9520 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9522 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9524 * alloc.c (Fgc_status): Do not access beyond zombies array
9525 boundary if nzombies > MAX_ZOMBIES.
9526 * alloc.c (dump_zombies): Add missing format specifier.
9528 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9530 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9531 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9533 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9534 Some packages use them to denote characters with modifiers.
9536 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9538 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9539 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9540 matching a pp-number. Rename parameter var to var1.
9542 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9544 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9546 2011-10-08 Glenn Morris <rgm@gnu.org>
9548 * callint.c (Fcall_interactively): Give a more explicit error for the
9549 'c' case with a non-character input. (Bug#8479)
9551 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9553 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9555 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9556 lines that are hscrolled on the left.
9558 * dispnew.c (buffer_posn_from_coords): Account for a possible
9559 presence of header-line. (Bug#4426)
9561 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
9563 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
9564 Don't advertise functionality which we discourage or doesn't work.
9566 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
9568 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
9569 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
9570 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
9571 this makes Emacs dump core during garbage collection on rare
9572 occasions. sizeof is obviously inferior to offsetof here, so
9573 stick with offsetof.
9574 (GC_POINTER_ALIGNMENT): New macro.
9575 (mark_memory): Omit 3rd (offset) arg; caller changed.
9576 Don't assume EMACS_INT alignment is the same as pointer alignment.
9578 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
9580 * keyboard.c (read_key_sequence_remapped): New var.
9581 (read_key_sequence): Compute remapping in the right buffer.
9582 (command_loop_1): Use read_key_sequence's remapping directly.
9584 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
9586 * dired.c (file_name_completion): Don't expand file name.
9587 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
9588 before checking file name handler.
9590 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
9591 they've been requested explicitly (bug#9591).
9593 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
9595 * keymap.c (Fsingle_key_description): Use make_specified_string
9596 instead of build_string to build string from push_key_description.
9599 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9601 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
9602 This fixes a Y2038 bug on 64-bit hosts.
9603 * buffer.c (reset_buffer):
9604 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
9605 (Fclear_buffer_auto_save_failure):
9606 Use 0, not -1, to represent an unset failure time, since time_t
9607 might not be signed.
9609 Remove dependency on glibc malloc internals.
9610 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9611 Move back here from lisp.h, but with their new implementations.
9612 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9613 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
9614 * charset.c (charset_table_init): New static var.
9615 (syms_of_charset): Use it instead of xmalloc. This removes a
9616 dependency on glibc malloc internals. See Eli Zaretskii's comment in
9617 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
9618 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9619 Move back to alloc.c.
9620 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9621 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
9623 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
9625 * nsterm.m (windowDidResize): Call x_set_window_size only when
9626 ns_in_resize is true. Otherwise set pixelwidth/height and
9627 call change_frame_size (Bug#9628).
9629 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9631 Port --enable-checking=all to Fedora 14 x86-64.
9632 * charset.c (syms_of_charset): Also account for glibc malloc's
9633 internal overhead when calculating the initial malloc maximum.
9635 Port --enable-checking=all to Fedora 14 x86.
9636 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9638 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
9639 (overrun_check_realloc, overrun_check_free):
9640 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
9641 That way, xmalloc returns a properly-aligned pointer even if
9642 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
9643 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
9644 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
9645 into account when calculating the initial malloc maximum.
9646 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9647 Move here from alloc.c, so that charset.c can use it too.
9648 Properly align; the old code wasn't right for common 32-bit hosts
9649 when configured with --enable-checking=all.
9650 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9651 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
9653 2011-09-29 Eli Zaretskii <eliz@gnu.org>
9655 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
9658 2011-09-28 Eli Zaretskii <eliz@gnu.org>
9660 * xdisp.c (compute_display_string_end): If there's no display
9661 string at CHARPOS, return -1.
9663 * bidi.c (bidi_fetch_char): When compute_display_string_end
9664 returns a negative value, treat the character as a normal
9665 character not covered by a display string. (Bug#9624)
9667 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
9669 * lread.c (Fread_from_string): Fix typo in docstring.
9671 2011-09-27 Eli Zaretskii <eliz@gnu.org>
9673 * xdisp.c (handle_invisible_prop): If invisible text ends on a
9674 newline, reseat the iterator instead of bidi-iterating there one
9675 character at a time. (Bug#9610)
9676 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
9677 TO_CHARPOS if the bidi iterator is at base embedding level.
9679 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
9681 * lread.c (readevalloop): Use correct code for NBSP.
9682 (read1): Likewise. (Bug#9608)
9684 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
9686 * dbusbind.c (Fdbus_register_signal): When service is not
9687 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
9689 2011-09-25 Glenn Morris <rgm@gnu.org>
9691 * buffer.c (truncate-lines): Doc fix.
9693 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
9695 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
9696 (Fset_window_next_buffers): Doc fix.
9698 2011-09-24 Glenn Morris <rgm@gnu.org>
9700 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
9702 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
9704 Fix minor problems found by static checking.
9705 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
9706 * indent.c (Fvertical_motion): Fix == vs = typo.
9708 2011-09-24 Eli Zaretskii <eliz@gnu.org>
9710 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
9711 Default value is now t. Doc fix.
9713 * indent.c (Fvertical_motion): Compute and apply the overshoot
9714 logic when moving up, not only when moving down. Fix the
9715 confusing name and values of the it_overshoot_expected variable;
9716 logic changes accordingly. (Bug#9254) (Bug#9549)
9718 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
9719 CHARPOS is covered by a display string which includes newlines.
9720 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
9721 is covered by a display string with embedded newlines.
9723 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
9725 * dbusbind.c (Fdbus_register_signal): Add match rule to
9726 Vdbus_registered_objects_table. (Bug#9581)
9727 (Fdbus_register_method, Vdbus_registered_objects_table):
9730 2011-09-24 Jim Meyering <meyering@redhat.com>
9732 do not ignore write error for any output size
9733 The previous change was incomplete.
9734 While it makes emacs --batch detect the vast majority of stdout
9735 write failures, errors were still ignored whenever the output size is
9736 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
9737 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
9738 && echo FAIL: ignored write error
9739 FAIL: ignored write error
9740 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
9741 && echo FAIL: ignored write error
9742 FAIL: ignored write error
9743 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
9745 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
9747 * emacs.c (Fkill_emacs): In noninteractive mode exit
9748 non-successfully if a write error occurred on stdout. (Bug#9574)
9750 2011-09-21 Eli Zaretskii <eliz@gnu.org>
9752 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
9755 * dispextern.h (struct it): Update the comment documenting what
9758 2011-09-20 Eli Zaretskii <eliz@gnu.org>
9760 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
9761 a display string, extend search for cursor position to end of row.
9762 (find_row_edges): If the row ends in a newline from a display
9763 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
9764 Handle the case of a display string with multiple newlines.
9765 (Fcurrent_bidi_paragraph_direction): Fix search for previous
9766 non-empty line. Fixes confusing cursor motion with arrow keys at
9767 the beginning of a line that starts with whitespace.

9776 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
9779 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9781 * xdisp.c (display_line): Record maximum and minimum buffer
9782 positions even if no glyphs were produced (e.g., by a zero-width
9783 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
9784 buffer positions that will be removed from the glyph row because
9786 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
9787 column is beyond frame width: don't subtract 1 "pixel" when
9788 computing width of the stretch.
9789 (reseat_at_next_visible_line_start): Undo the change made on
9790 2011-09-17 that saved paragraph information and restored it after
9791 the call to `reseat'. (Bug#9545)
9793 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9795 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
9796 and turn window cursor on if cleared (Bug#9415).

9807 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
9809 Fix minor problem found by static checking.
9810 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
9811 initialized, to pacify gcc -Wuninitialized.
9813 * fileio.c: Report proper errno when syscall falls.
9814 (Finsert_file_contents): Save and restore errno,
9815 so that report_file_error outputs the correct diagnostic.
9816 (Fwrite_region) [CLASH_DETECTION]: Likewise.
9818 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9820 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
9822 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9824 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
9825 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
9827 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9829 * xdisp.c (reseat_at_next_visible_line_start): Keep information
9830 about the current paragraph and restore it after the call to reseat.
9832 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
9833 (bidi_find_paragraph_start): Search back for paragraph beginning
9834 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
9835 (bidi_move_to_visually_next): Only trigger paragraph-related
9836 computations when the last character is a newline or at EOB, not
9837 just any NEUTRAL_B. (Bug#9470)
9839 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
9840 truncated lines if point is covered by a display string. (Bug#9524)
9842 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
9844 * xselect.c: Relax test for outgoing X longs (Bug#9498).
9845 (cons_to_x_long): New function.
9846 (lisp_data_to_selection_data): Use it. Correct the test for
9847 short-versus-long data; it was negated. Break out of vector
9848 loop, for efficiency, when a long datum is discovered.
9850 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
9852 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
9854 2011-09-16 Eli Zaretskii <eliz@gnu.org>
9856 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
9857 GCC PR/17406) by declaring this function with external scope.

9880 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
9881 This occurs when processing a multibyte format.
9882 Problem reported by Wolfgang Jenker.
9884 2011-09-15 Johan Bockgård <bojohan@gnu.org>
9886 * xdisp.c (try_cursor_movement): Only check for exact match if
9887 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
9889 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9891 Remove unused external symbols.
9892 * dispextern.h (calc_pixel_width_or_height): Remove decl.

9895 * indent.c (check_display_width):
9896 * w32term.c: Fix comment to match code.
9897 * xterm.c, xterm.h (x_catching_errors): Remove.
9899 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9901 * xselect.c: Use signed conversions more consistently (Bug#9498).
9902 (selection_data_to_lisp_data): Assume incoming selection data are
9903 signed integers, not unsigned. This is to be consistent with
9904 outgoing selection data, which was modified to use signed integers
9905 in as part of the fix to Bug#9196 in response to Jan D.'s comment
9906 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
9907 expects long, not unsigned long.

9911 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
9912 computation of loop end. Reported by Johan Bockgård
9915 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
9917 * frame.c (Fother_visible_frames_p): Function deleted.
9919 2011-09-12 Eli Zaretskii <eliz@gnu.org>
9921 * indent.c (compute_motion): Process display vector front to back
9922 rather than the other way around. (Bug#2496)
9924 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
9926 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
9928 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
9930 * minibuf.c (Fread_from_minibuffer): Doc fix.
9932 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9934 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
9935 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
9937 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
9939 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
9940 value for non-existent files.
9942 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9944 * fileio.c (Finsert_file_contents): If the file cannot be opened,
9945 set its "size" to -1. This will set the modtime_size field of
9946 the corresponding buffer to -1, which is what
9947 verify-visited-file-modtime expects for files that do not exist.
9950 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
9952 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
9954 * lisp.h: ... from here. push_key_description is no longer
9955 defined in keyboard.c, so its declaration should not be in
9956 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
9957 logically belongs with push_key_description.
9959 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
9961 * buffer.h: Include <sys/types.h> instead of <time.h>.
9962 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
9963 Problem reported by Herbert J. Skuhra.
9965 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
9967 * xml.c (parse_region): Make the parsing work for
9968 non-comment-starting XML files again (bug#9144).
9970 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
9972 * image.c (gif_load): Fix calculation of bottom and right corner.
9975 2011-09-10 Eli Zaretskii <eliz@gnu.org>
9977 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
9978 redisplay in small windows.
9980 2011-09-09 Eli Zaretskii <eliz@gnu.org>
9982 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
9984 2011-09-08 Martin Rudalics <rudalics@gmx.at>
9986 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
9987 Operate on live windows only.
9989 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
9991 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
9993 2011-09-07 Eli Zaretskii <eliz@gnu.org>
9995 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
9996 only under bidi iteration.
9998 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10000 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10002 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10004 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10005 Without this fix, the command to link temacs failed due to an
10006 undefined symbol __builtin_isnan. This is because
10007 /usr/include/iso/math_c99.h #defines isnan(x) to
10008 __builtin_isnan(x), but the bundled gcc, which identifies itself
10009 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10011 * floatfns.c (isnan): #undef, and then #define to a clone of
10013 (Fisnan): Always define, since it's always available now.
10014 (syms_of_floatfns): Always define isnan at the Lisp level.
10016 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10018 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10020 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10022 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10023 The previous code assumed that file offsets (off_t values) fit in
10024 EMACS_INT variables, which is not true on typical 32-bit hosts.
10025 The code messed up by falsely reporting buffer overflow in cases
10026 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10027 when "big" contains more than 2**29 bytes, even though this
10028 inserts just one byte and does not overflow the buffer.
10029 (Finsert_file_contents): Store file offsets as off_t
10030 values, not as EMACS_INT values. Check for overflow when
10031 converting between EMACS_INT and off_t. When checking for
10032 buffer overflow or for overlap, take the offsets into account.
10033 Don't use EMACS_INT for small values where int suffices.
10034 When checking for overlap, fix a typo: ZV was used where
10035 ZV_BYTE was intended.
10036 (Fwrite_region): Don't assume off_t fits into 'long'.
10037 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10039 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10041 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10043 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10045 sprintf-related integer and memory overflow issues (Bug#9412).
10047 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10048 (esprintf, exprintf, evxprintf): New functions.
10049 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10050 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10051 (modify_event_symbol): Do not assume that the length of
10052 name_alist_or_stem is safe to alloca and fits in int.
10053 (Fexecute_extended_command): Likewise for function name and binding.
10054 (Frecursion_depth): Wrap around reliably on integer overflow.
10055 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10056 since some callers pass EMACS_INT values.
10057 (Fsingle_key_description): Don't crash if symbol name contains more
10058 than MAX_ALLOCA bytes.
10059 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10060 (get_minibuffer): Arg is now EMACS_INT, not int.
10061 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10062 (esprintf, exprintf, evxprintf): New decls.
10063 * window.h (command_loop_level, minibuf_level): Reflect API changes.
10065 * dbusbind.c (signature_cat): New function.
10066 (xd_signature, Fdbus_register_signal):
10067 Do not overrun buffer; instead, report string overflow.
10069 * dispnew.c (add_window_display_history): Don't overrun buffer.
10070 Truncate instead; this is OK since it's just a log.
10072 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10073 even if the time zone offset is outlandishly large.
10074 Don't mishandle offset == INT_MIN.
10076 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10077 when creating daemon; the previous buffer-overflow check was incorrect.
10079 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10080 which has the guts of the old verror function.
10082 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10083 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10085 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10086 (font_unparse_xlfd): Don't blindly alloca long strings.
10087 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10088 fits in int, when using sprintf. Use single snprintf to count
10089 length of string rather than counting it via multiple sprintfs;
10090 that's simpler and more reliable.
10091 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10092 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10093 sprintf, in case result does not fit in int.
10095 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10096 (fontset_from_font): Print it.
10098 * frame.c (tty_frame_count): Now printmax_t, not int.
10099 (make_terminal_frame, set_term_frame_name): Print it.
10100 (x_report_frame_params): In X, window IDs are unsigned long,
10101 not signed long, so print them as unsigned.
10102 (validate_x_resource_name): Check for implausibly long names,
10103 and don't assume name length fits in 'int'.
10104 (x_get_resource_string): Don't blindly alloca invocation name;
10105 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10108 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10109 (xg_check_special_colors, xg_set_geometry):
10110 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10112 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10113 Use esprintf, not sprintf, in case result does not fit in int.
10115 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10116 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10117 it as a large positive number.
10118 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10119 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10121 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10122 in case result does not fit in int.
10124 * print.c (float_to_string): Detect width overflow more reliably.
10125 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10126 buffer overrun. Don't assume list length fits in 'int'. Treat
10127 print length of 0 as 0, not as infinity; to be consistent with other
10128 uses of print length in this function. Don't overflow print length
10129 index. Don't assume hash table size fits in 'long', or that
10130 vectorlike size fits in 'unsigned long'.
10132 * process.c (make_process): Use printmax_t, not int, to format
10133 process-name gensyms.
10135 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10137 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10138 to avoid potential buffer overrun.
10140 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10141 if X resource line is longer than 512 bytes.
10143 * xfns.c (x_window): Make sprintf buffer a bit bigger
10144 to avoid potential buffer overrun.
10146 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10148 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10150 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10152 Integer overflow fixes for scrolling, etc.
10153 Without these, Emacs silently mishandles large integers sometimes.
10154 For example, "C-u 4294967297 M-x recenter" was treated as if
10155 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10157 * xdisp.c (try_window_id): Check Emacs fixnum range before
10158 converting to 'int'.
10160 * window.c (window_scroll_line_based, Frecenter):
10161 Check that an Emacs fixnum is in range before assigning it to 'int'.
10162 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10163 values converted from Emacs fixnums.
10164 (Frecenter): Don't wrap around a line count if it is out of 'int'
10165 range; instead, treat it as an extreme value.
10166 (Fset_window_configuration, compare_window_configurations):
10167 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10169 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10170 that can exceed INT_MAX. Check that EMACS_INT value is in range
10171 before assigning it to the (possibly-narrower) index.
10172 (match_limit): Don't assume that a fixnum can fit in 'int'.
10174 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10177 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10178 (Fvertical_motion): Don't wrap around LINES values that don't fit
10179 in 'int'. Instead, treat them as extreme values. This is good
10180 enough for windows, which can't have more than INT_MAX lines anyway.
10182 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10184 * Require libxml/parser.h to avoid compilation warning.
10186 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10188 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10189 since this reportedly can destroy thread storage.
10191 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10193 * syntax.c (find_defun_start): Update all cache variables if
10194 exiting early (Bug#9401).
10196 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10198 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10200 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10201 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10202 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10204 * term.c (tty_append_glyph): New function.
10205 (produce_stretch_glyph): Static function and its prototype deleted.
10207 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10210 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10212 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10213 when checking :margin (Bug#9390).
10214 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10215 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10216 so that the name doesn't mislead. All uses changed.
10218 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10220 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
10223 2011-08-27 Eli Zaretskii <eliz@gnu.org>
10225 * xdisp.c (move_it_to): Don't bail out early when reaching
10226 position beyond to_charpos, if we are scanning backwards.
10227 (move_it_vertically_backward): When DY == 0, make sure we get to
10228 the first character in the line after the newline.
10230 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10232 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10233 (ccl_driver): Do not generate an out-of-range pointer.
10234 (Fccl_execute_on_string): Remove unnecessary check for
10235 integer overflow, noted by Stefan Monnier in
10236 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10237 Remove a FIXME that didn't need fixing.
10238 Simplify the newly-introduced buffer reallocation code.
10240 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10242 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10244 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10246 Integer and memory overflow issues (Bug#9196).
10248 * doc.c (get_doc_string): Rework so that
10249 get_doc_string_buffer_size is the actual buffer size, rather than
10250 being 1 less than the actual buffer size; this makes xpalloc more
10253 * image.c (x_allocate_bitmap_record, cache_image):
10254 * xselect.c (Fx_register_dnd_atom):
10255 Simplify previous changes by using xpalloc.
10257 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10258 since either will do and ptrdiff_t is convenient with xpalloc.
10260 * charset.c (charset_table_size)
10261 (struct charset_sort_data.priority): Now ptrdiff_t.
10262 (charset_compare): Don't overflow if priorities differ greatly.
10263 (Fsort_charsets): Don't assume list length fits in int.
10264 Check for size-calculation overflow when allocating sort data.
10265 (syms_of_charset): Allocate an initial charset table that is
10266 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10268 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10270 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10271 The actual value is always <= INT_MAX, and leaving it unsigned made
10272 overflow checking harder.
10274 * dispextern.h (struct glyph_matrix.rows_allocated)
10275 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10276 with xpalloc. The values are still always <= INT_MAX.
10278 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10280 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10281 (SAFE_NALLOCA): New macro.
10283 * region-cache.c (struct boundary.pos, find_cache_boundary)
10284 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10285 (set_cache_region, invalidate_region_cache)
10286 (revalidate_region_cache, know_region_cache, region_cache_forward)
10287 (region_cache_backward, pp_cache):
10288 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10289 so that ptrdiff_t * can be passed to xpalloc.
10290 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
10291 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
10292 (pp_cache): Don't assume cache_len fits in int.
10293 * region-cache.h: Adjust extern decls to match.
10295 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
10296 EMACS_INT, since either will do, for xpalloc.
10298 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
10299 (xnmalloc, xnrealloc, xpalloc): New functions.
10301 * bidi.c (bidi_shelve_header_size): New constant.
10302 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
10303 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
10305 * bidi.c (bidi_cache_shrink):
10306 * buffer.c (overlays_at, overlays_in, record_overlay_string)
10308 Don't update size of array until after memory allocation succeeds,
10309 because xmalloc/xrealloc may not return.
10310 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10311 now that we have proper integer overflow checking.
10312 (record_overlay_string, overlay_strings): Catch overflows when
10313 calculating size of overlay_str_buf.
10315 * callproc.c (Fcall_process): Check for size overflow when
10316 calculating size of args2.
10317 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
10318 Normally we prefer signed values, but sticking with ptrdiff_t would
10319 require adding more-complicated checks.
10321 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10322 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
10323 Redo buffer-overflow calculations to avoid integer overflow.
10324 Add a FIXME comment where memory seems to be over-allocated.
10326 * character.c (Fstring): Check for size-calculation overflow.
10328 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
10329 unnecessary integer overflow. Check for size overflow.
10330 (encode_coding_object): Don't update size until xmalloc succeeds.
10332 * composite.c (get_composition_id): Check for overflow in glyph
10333 length calculations.
10335 Integer and memory overflow fixes for display code.
10336 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
10337 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
10338 (scrolling_window): Check for overflow in size calculations.
10339 (line_draw_cost, realloc_glyph_pool, add_row_entry):
10340 Don't assume glyph table len fits in int.
10341 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
10342 (row_table_size): Now ptrdiff_t, not int.
10343 (scrolling_window): Avoid overflow in size calculations.
10344 Don't update size until allocation succeeds.
10345 * fns.c (concat): Check for overflow in size calculations.
10346 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
10347 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
10348 (NEXT_ALMOST_PRIME_LIMIT): New constant.
10350 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
10351 (get_doc_string): Check for size calculation overflow.
10352 Don't update size until allocation succeeds.
10353 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
10354 EMACS_INT, where ptrdiff_t will do.
10355 (Fsubstitute_command_keys): Check for string overflow.
10357 * editfns.c (set_time_zone_rule): Don't assume environment length
10359 (message_length): Now ptrdiff_t, not int.
10360 (Fmessage_box): Don't update size until allocation succeeds.
10361 Don't assume message length fits in int.
10362 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10364 * emacs.c (main): Do not reallocate argv, since there is a null at
10365 the end that can be overwritten, and this way there's no need to
10366 worry about size-calculation overflow.
10367 (sort_args): Check for size-calculation overflow.

10376 (x_set_alpha): Do not assume XINT fits in int.
10378 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10379 This is for the members text_lines, text_cols, total_lines, total_cols,
10380 where the system imposes an 'int' limit.

10389 Check for size-calculation overflow.
10390 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10391 do, as we prefer signed integers.

10447 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
10448 for command line length. Do not attempt to address one before the
10449 beginning of an array, as that's not portable.

10479 Check for size calculation overflow.
10480 (cache_face): Treat size calculation overflows as if they were
10481 memory exhaustion (the usual treatment), rather than aborting.
10483 * xfns.c (x_encode_text, x_set_name_internal)
10484 (Fx_change_window_property): Use ptrdiff_t, not int, to count
10485 sizes, since they can exceed INT_MAX in size. Check for size
10486 calculation overflow.

10489 (xg_select): Check for size calculation overflow.
10490 Don't update size until alloc done.
10492 * xrdb.c (get_environ_db): Don't assume path length fits in int,
10493 as sprintf is limited to int lengths.
10495 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
10496 (X_LONG_MIN): New macros.
10497 Use them to make the following changes clearer.
10498 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
10499 This change doesn't affect the value now, but it may help remind
10500 future maintainers not to raise the value too much later.
10501 (SELECTION_QUANTUM): Remove, replacing with ...
10502 (selection_quantum): ... new function, which avoids overflow.
10504 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10505 assumption that selection length fits in 'int'.

10522 Don't store size until memory allocation succeeds.
10523 (x_get_window_property): Plug memory leak on memory exhaustion.
10524 Don't double-block input; malloc is safe here. Don't assume 2**34
10525 - 4 fits in unsigned long. Add an xassert to check
10526 XGetWindowProperty overflow. Be more careful about overflow
10527 calculations, and distinguish size from memory overflow better.
10528 (receive_incremental_selection): When tracing, don't assume
10529 unsigned int is less than INT_MAX.
10530 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

10533 in the range -65535 through -1 fit in an X unsigned short.
10534 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10535 result parameters unless successful. Rely on cons_to_unsigned
10536 to report problems with elements; the old code wasn't right anyway.
10537 (x_check_property_data): Check for int overflow; we cannot use
10538 a wider type due to X limits.
10539 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

10571 * lisp.h (hash_lookup, hash_put):
10572 * minibuf.c (Ftest_completion):
10573 Use ptrdiff_t for hash table indexes, not int (which is too
10574 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
10575 32-bit --with-wide-int hosts).
10577 * charset.c (Fdefine_charset_internal): Check for integer overflow.
10578 Add a FIXME comment about memory leaks.

10586 with outlandish widths.
10587 * character.h (sanitize_tab_width): Rename from sanitize_width,
10588 now that we have two such functions. All uses changed.

10606 * xterm.c: Don't go over XClientMessageEvent limit.
10607 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
10608 (x_send_scroll_bar_event): Likewise. Check that the size does not
10609 exceed limits imposed by XClientMessageEvent, as well as the usual
10610 ptrdiff_t and size_t limits.
10612 * keyboard.c: Overflow, signedness and related fixes.
10613 (make_lispy_movement): Use same integer type in forward decl
10614 that is used in the definition.
10615 (read_key_sequence, keyremap_step):
10616 Change bufsize argument back to int, undoing my 2011-03-30 change.
10617 We prefer signed types, and int is wide enough here.
10618 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
10619 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
10620 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
10621 length, not size_t. Use ptrdiff_t for index, not int.
10622 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
10623 possibility of integer overflow.

10651 Prefer int to unsigned where either will do.
10652 (tiff_handler): New function, combining the cores of the
10653 old tiff_error_handler and tiff_warning_handler.
10654 This function is rewritten to use vsnprintf and thereby avoid
10655 stack buffer overflows. It uses only the features of vsnprintf
10656 that are common to both POSIX and native Microsoft.
10657 (tiff_error_handler, tiff_warning_handler): Use it.
10658 (tiff_load, gif_load, imagemagick_load_image):
10659 Don't assume :index value fits in 'int'.
10660 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
10661 (imagemagick_load_image): Check that crop parameters fit into
10662 the integer types that MagickCropImage accepts. Don't assume
10663 Vimagemagick_render_type has a nonnegative value. Don't assume
10664 size_t fits in 'long'.
10665 (gs_load): Use printmax_t to print the widest integers possible.

10679 (handle_single_display_spec): If the display spec is of the form
10680 `(space ...)', and specifies display in the text area, return 2
10682 (try_cursor_movement): Check for the need to scroll more
10683 accurately, and prefer exact match for point under bidi.
10684 Don't advance `row' beyond the last row of the window.

10702 buffers, return left-to-right.
10703 (set_cursor_from_row): Consider candidate row a win if its glyph
10704 represents a newline and point is on that newline. Fixes cursor
10705 positioning on the newline at EOL of R2L text within L2R
10706 paragraph, and vice versa.
10707 (try_cursor_movement): Check continued rows, in addition to
10708 continuation rows. Fixes unwarranted scroll when point enters a
10709 continued line of R2L text within an L2R paragraph, or vice versa.
10710 (cursor_row_p): Consider the case of point being equal to
10711 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
10712 from the end of a short line to the beginning of a continued line
10713 of R2L text within L2R paragraph.
10714 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

10737 * xdisp.c (redisplay_window): When computing centering_position,
10738 account for the height of the header line. (Bug#8874)
10740 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
10741 instead of CHAR_TO_BYTE. Fixes a crash when a completion
10742 candidate is selected by the mouse, and that candidate has a
10743 composed character under the mouse.
10745 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
10746 coordinates reported by pos-visible-in-window-p for a composed
10747 character in column zero.
10749 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

10753 2011-08-22 Eli Zaretskii <eliz@gnu.org>
10755 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
10756 consider it a hit if to_charpos is anywhere in the range of the
10757 composed buffer positions.
10759 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
10761 * image.c (gif_load): Don't assume that each subimage has the same
10762 dimensions as the base image. Handle disposal method that is
10763 "undefined" by the gif spec (Bug#9335).
10765 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
10767 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

10772 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
10773 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
10774 from an Org mode buffer to a Speedbar frame.
10776 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
10777 a composition, take its buffer position from IT->cmp_it.charpos.
10778 Fixes cursor positioning at the beginning of a line that begins
10779 with a composed character.
10781 2011-08-18 Eli Zaretskii <eliz@gnu.org>
10783 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
10784 character bidirectional type, use STRONG_L instead. Fixes crashes
10785 in a buffer produced by `describe-categories'.
10787 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
10788 members before the level stack, so they would be saved and
10789 restored when copying iterator state. Fixes incorrect reordering
10790 around TABs covered by display properties.
10792 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
10794 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

10804 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
10805 has no `load' handler, try opening the file locally. (Bug#9311)
10807 2011-08-16 Ken Brown <kbrown@cornell.edu>
10809 * gmalloc.c: Expand comment.
10811 2011-08-16 Eli Zaretskii <eliz@gnu.org>
10813 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
10814 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
10816 2011-08-16 Ken Brown <kbrown@cornell.edu>
10818 Fix memory allocation problems in Cygwin build (Bug#9273).
10820 * unexcw.c ( __malloc_initialized): Declare external variable.
10821 (fixup_executable): Force the dumped emacs to reinitialize malloc.
10823 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
10825 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
10827 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
10828 in the static heap.
10829 [CYGWIN] (special_realloc): New function.
10830 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
10831 requests to realloc storage in the static heap.
10833 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
10835 * bidi.c (bidi_initialize): Remove unused local.
10837 2011-08-15 Eli Zaretskii <eliz@gnu.org>
10840 * biditype.h: Remove file.

10842 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
10844 * dispextern.h: Fix a typo in the comment to bidi_type_t.
10846 * chartab.c: Improve commentary for the uniprop_table API.
10848 * bidi.c (bidi_paragraph_init): Support zero value of
10849 bidi_ignore_explicit_marks_for_paragraph_level.
10850 (bidi_initialize): Use uniprop_table instead of including
10851 biditype.h and bidimirror.h.
10853 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
10854 coordinates of the iterator when restoring from ppos_it.
10857 2011-08-14 Kenichi Handa <handa@m17n.org>
10859 * process.c (create_process): Call setup_process_coding_systems
10860 after the pid of the process is set to -1 (Bug#8162).
10862 2011-08-14 Eli Zaretskii <eliz@gnu.org>
10864 * xdisp.c (move_it_in_display_line_to): Don't invoke
10865 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
10866 ppos_it. Fixes vertical cursor motion when line beginning is
10867 covered by an image. (Bug#9296)
10869 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
10871 * nsterm.h (ns_run_ascript): Declare.
10872 (NSAPP_DATA2_RUNASSCRIPT): Define.
10874 * nsfns.m (as_script, as_result, as_status): New static variables.
10875 (ns_run_ascript): New function.
10876 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
10877 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
10878 the event loop. Get status from as_status (Bug#7276).
10880 * nsterm.m (sendEvent): If event is NSApplicationDefined and
10881 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
10882 the event loop (Bug#7276).
10884 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
10886 * gnutls.c (QCgnutls_bootprop_priority)
10887 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
10888 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
10889 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
10890 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
10891 (QCgnutls_bootprop_verify_hostname_error)
10892 (QCgnutls_bootprop_callbacks_verify): Rename from
10893 Qgnutls_bootprop_..., all uses changed.
10895 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
10898 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
10900 * xfaces.c (Qframe_set_background_mode): Now static.
10901 * dispextern.h (Qframe_set_background_mode): Remove decl.

10905 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
10907 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
10908 (Fnetwork_interface_list): Allocate in increments of bytes instead
10909 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
10910 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
10912 (struct ifflag_def): notrailers is smart on OSX.
10913 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
10914 Get hardware address with getifaddrs if available.
10916 2011-08-12 Eli Zaretskii <eliz@gnu.org>
10918 * xdisp.c (iterate_out_of_display_property): xassert that
10919 IT->position is set to within IT->object's boundaries. Break from
10920 the loop as soon as EOB is reached; avoids infloops in redisplay
10921 when IT->position is set up wrongly due to some bug.
10922 Set IT->current to match the bidi iterator unconditionally.
10923 (push_display_prop): Allow GET_FROM_STRING as IT->method on
10924 entry. Force push_it to save on the stack the current
10925 buffer/string position, to be restored by pop_it. Fix flags in
10926 the iterator structure wrt the object coming from a display
10927 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
10928 properties. (Bug#9284)
10930 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
10932 * fontset.c (fontset_get_font_group): Add proper type checks.
10935 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10937 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
10938 and LC_VERSION_MIN_MACOSX.
10939 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
10940 (dump_it) [LC_FUNCTION_STARTS]: Use it.
10942 2011-08-08 Eli Zaretskii <eliz@gnu.org>
10944 * xdisp.c (forward_to_next_line_start): Allow to use the
10945 no-display-properties-and-no-overlays under bidi display.
10946 Set disp_pos in the bidi iterator to avoid searches for display
10947 properties and overlays.
10949 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
10951 * editfns.c (Fset_time_zone_rule): Document relationship with the
10954 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
10955 the font entity extracted from the cache (Bug#8109).
10957 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
10959 * composite.c (autocmp_chars): Don't reset point. That is done by
10960 restore_point_unwind (Bug#5984).
10962 2011-08-07 Juri Linkov <juri@jurta.org>
10964 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
10965 to show the arg `TIME' instead of `TIMEVAL'.
10967 2011-08-06 Eli Zaretskii <eliz@gnu.org>
10969 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
10970 display property strides EOL and includes a newline, as in
10971 longlines-mode. (Bug#9254)
10972 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
10973 word-wrap under bidirectional display. (Bug#9224)
10975 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
10976 is non-zero, even if the data buffer is NULL. Fixes a crash in
10977 vertical-motion with longlines-mode. (Bug#9254)
10979 2011-08-05 Eli Zaretskii <eliz@gnu.org>
10981 * bidi.c <bidi_cache_total_alloc>: Now static.
10982 (bidi_initialize): Initialize bidi_cache_total_alloc.
10984 * xdisp.c (display_line): Release buffer allocated for shelved bidi
10987 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
10988 amount allocated this far in `bidi_cache_total_alloc'.
10989 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
10990 non-zero, only free the data buffer without restoring the cache
10991 contents. All callers changed.
10993 * dispextern.h (bidi_unshelve_cache): Update prototype.
10995 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
10996 (move_it_in_display_line, move_it_to)
10997 (move_it_vertically_backward, move_it_by_lines): Replace the call
10998 to xfree to an equivalent call to bidi_unshelve_cache.
10999 (move_it_in_display_line_to): Fix logic of returning
11000 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
11002 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11004 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
11005 came from a string character with a `cursor' property. (Bug#9229)
11007 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11009 * Makefile.in (LIB_PTHREAD): New variable.
11010 (LIBES): Add LIB_PTHREAD (Bug#9216).
11012 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
11013 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
11015 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
11017 * regex.c (re_iswctype): Remove some redundant boolean conversions.
11019 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11021 * xterm.c (x_find_topmost_parent): New function.
11022 (x_set_frame_alpha): Find topmost parent window with
11023 x_find_topmost_parent and set the property there also (bug#9181).
11024 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
11026 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
11028 * callproc.c (Fcall_process): Avoid vfork clobbering
11029 the local vars buffer, coding_systems, current_dir.
11031 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
11033 * keymap.c (Fmake_composed_keymap): Move to subr.el.
11035 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
11037 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
11038 so that it is not optimized away.
11040 * xdisp.c (compute_display_string_pos): Remove unused local.
11042 2011-08-02 Eli Zaretskii <eliz@gnu.org>
11044 Fix slow cursor motion and scrolling in large buffers with
11045 selective display, like Org Mode buffers. (Bug#9218)
11047 * dispextern.h (struct bidi_it): New member disp_prop_p.
11049 * xdisp.c: Remove one-slot cache of display string positions.
11050 (compute_display_string_pos): Accept an additional argument
11051 DISP_PROP_P; callers changed. Scan at most 5K characters forward
11052 for a display string or property. If found, set DISP_PROP_P
11055 * bidi.c (bidi_fetch_char): Accept an additional argument
11056 DISP_PROP_P, and pass it to compute_display_string_pos.
11057 Only handle text covered by a display string if DISP_PROP_P is returned
11058 non-zero. All callers of bidi_fetch_char changed.
11060 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
11062 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
11064 2010-12-03 Don March <don@ohspite.net>
11066 * keymap.c (Fdefine_key): Fix non-prefix key error message when
11067 last character M-[char] is translated to ESC [char] (bug#7541).
11069 2011-08-02 Kenichi Handa <handa@m17n.org>
11071 * lisp.h (uniprop_table): Extern it.
11073 * chartab.c (uniprop_table): Make it non-static.
11075 2011-08-01 Eli Zaretskii <eliz@gnu.org>
11077 * xdisp.c (forward_to_next_line_start): Accept additional argument
11078 BIDI_IT_PREV, and store into it the state of the bidi iterator had
11080 (reseat_at_next_visible_line_start): Use the bidi iterator state
11081 returned by forward_to_next_line_start to restore the state of
11082 it->bidi_it after backing up to previous newline. (Bug#9212)
11084 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
11086 * regex.c (re_comp): Protoize.
11087 (re_exec): Fix return type.
11088 (regexec): Fix type of `ret'. (Bug#9203)
11090 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11092 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
11093 This is needed if max-image-size is a floating-point number.
11095 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11097 * print.c (print_object): Print empty symbol as ##.
11099 * lread.c (read1): Read ## as empty symbol.
11101 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11103 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
11104 setting frame foreground color (Bug#9175).
11105 (x_set_background_color): Likewise.
11107 * nsmenu.m (-setText): Size tooltip dimensions precisely to
11108 contents (Bug#9176).
11109 (EmacsTooltip -init): Remove bezels and add shadows to
11112 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
11113 or scroll bar (Bug#8470).
11115 * nsfont.m (nsfont_open): Remove assignment to voffset and
11116 unnecessary vars hshink, expand, hd, full_height, min_height.
11117 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
11119 * nsterm.h (nsfont_info): Remove voffset field.
11121 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11123 Implement strike-through and overline on NextStep (Bug#8863).
11125 * nsfont.m (nsfont_open): Use underline position provided by font,
11126 instead of hard-coded value of 2.
11127 (nsfont_draw): Call ns_draw_text_decoration instead.
11129 * nsterm.h: Add declaration for ns_draw_text_decoration.
11131 * nsterm.m (ns_draw_text_decoration): New function for drawing
11132 underline, overline, and strike-through.
11133 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
11134 ns_draw_text_decoration. Change treatment of cursor drawing to
11135 accommodate underlining, etc.
11137 2011-07-28 Eli Zaretskii <eliz@gnu.org>
11139 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
11142 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11144 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11145 Without this fix, if a signal arrives just after memory fills up,
11146 'malloc' might be invoked reentrantly.
11148 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11149 In other words, assume that every image size is allowed, on non-X
11150 hosts. This assumption is probably wrong, but it lets Emacs compile.
11152 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11154 * regex.c (re_iswctype): Convert return values to boolean.
11156 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
11158 * xdisp.c (compute_display_string_pos): Don't use cached display
11159 string position if the buffer had its restriction changed.
11162 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11164 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11166 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11168 Integer signedness and overflow and related fixes. (Bug#9079)
11170 * bidi.c: Integer size and overflow fixes.
11171 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
11172 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
11173 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11174 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11175 (bidi_find_other_level_edge):
11176 Use ptrdiff_t instead of EMACS_INT where either will do.
11177 This works better on 32-bit hosts configured --with-wide-int.
11178 (bidi_cache_ensure_space): Check for size-calculation overflow.
11179 Use % rather than repeated addition, for better worst-case speed.
11180 Don't set bidi_cache_size until after xrealloc returns, because it
11182 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11183 (bidi_cache_ensure_space): Also check that the bidi cache size
11184 does not exceed that of the largest Lisp string or buffer. See Eli
11185 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11187 * alloc.c (__malloc_size_t): Remove.
11188 All uses replaced by size_t. See Andreas Schwab's note
11189 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11191 * image.c: Improve checking for integer overflow.
11192 (check_image_size): Assume that f is nonnull, since
11193 it is always nonnull in practice. This is one less thing to
11194 worry about when checking for integer overflow later.
11195 (x_check_image_size): New function, which checks for integer
11196 overflow issues inside X.
11197 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11198 This removes the need for a memory_full check.
11199 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11200 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11201 (xbm_read_bitmap_data): Change locals back to 'int', since
11202 their values must fit in 'int'.
11203 (xpm_load_image, png_load, tiff_load):
11204 Invoke x_create_x_image_and_pixmap earlier,
11205 to avoid much needless work if the image is too large.
11206 (tiff_load): Treat overly large images as if
11207 x_create_x_image_and_pixmap failed, not as malloc failures.
11208 (gs_load): Use x_check_image_size.
11210 * gtkutil.c: Omit integer casts.
11211 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11212 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11214 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11216 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11217 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11218 would wrongly return t on a 64-bit host.
11220 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11221 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11222 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11223 and therefore cause GCC to emit a bogus diagnostic in some cases.
11225 * image.c: Integer signedness and overflow and related fixes.
11226 This is not an exhaustive set of fixes, but it's time to
11227 record what I've got.
11228 (lookup_pixel_color, check_image_size): Remove redundant decls.
11229 (check_image_size): Don't assume that arbitrary EMACS_INT values
11230 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11231 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11232 (tiff_load, imagemagick_load_image):
11233 Check for overflow in size calculations.
11234 (x_create_x_image_and_pixmap): Remove unnecessary test for
11235 xmalloc returning NULL; that can't happen.
11236 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11237 (xpm_color_bucket): Use better integer hashing function.
11238 (xpm_cache_color): Don't possibly over-allocate memory.
11239 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11240 (gif_memory_source):
11241 Use ptrdiff_t, not int or size_t, to record sizes.
11242 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11243 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11244 either works, as we prefer signed integers.
11245 (tiff_read_from_memory, tiff_write_from_memory):
11246 Return tsize_t, not size_t, since that's what the TIFF API wants.
11247 (tiff_read_from_memory): Don't fail simply because the read would
11248 go past EOF; instead, return a short read.
11249 (tiff_load): Omit no-longer-needed casts.
11250 (Fimagemagick_types): Don't assume size fits into 'int'.
11252 Improve hashing quality when configured --with-wide-int.
11253 * fns.c (hash_string): New function, taken from sxhash_string.
11254 Do not discard information about ASCII character case; this
11255 discarding is no longer needed.
11256 (sxhash-string): Use it. Change sig to match it. Caller changed.
11257 * lisp.h: Declare it.
11258 * lread.c (hash_string): Remove, since we now use fns.c's version.
11259 The fns.c version returns a wider integer if --with-wide-int is
11260 specified, so this should help the quality of the hashing a bit.
11262 * emacs.c: Integer overflow minor fix.
11263 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11264 Define only if GNU_LINUX.
11265 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11267 * dispnew.c: Integer signedness and overflow fixes.
11268 Remove unnecessary forward decls, that were a maintenance hassle.
11269 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11271 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11272 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11273 (prepare_desired_row, line_draw_cost):
11274 Use int, not unsigned, where either works.
11275 (save_current_matrix, restore_current_matrix):
11276 Use ptrdiff_t, not size_t, where either works.
11277 (init_display): Check for overflow more accurately, and without
11278 relying on undefined behavior.
11280 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11281 Remove, replacing with the new symbols in lisp.h. All uses changed.
11282 * fileio.c (make_temp_name):
11283 * filelock.c (lock_file_1, lock_file):
11284 * xdisp.c (message_dolog):
11285 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11286 Use pMd etc. instead.
11287 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11288 replacing the pWIDE etc. symbols removed from editfns.c.
11290 * keyboard.h (num_input_events): Now uintmax_t.
11291 This is (very slightly) less likely to mess up due to wraparound.
11294 * buffer.c: Integer signedness fixes.
11295 (alloc_buffer_text, enlarge_buffer_text):
11296 Use ptrdiff_t rather than size_t when either will do, as we prefer
11299 * alloc.c: Integer signedness and overflow fixes.
11300 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11301 (__malloc_size_t): Default to size_t, not to int.
11302 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11303 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11304 Prefer ptrdiff_t to size_t when either would do, as we prefer
11306 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11307 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11308 Now const. Initialize with values that are in range even if char
11310 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11311 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11312 These functions do the right thing with sizes > 2**32.
11313 (check_depth): Now ptrdiff_t, not int.
11314 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11315 Adjust to new way of storing sizes. Check for size overflow bugs
11317 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11318 slightly wrong anyway, as it missed one instance of
11319 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11320 (refill_memory_reserve): Omit needless cast to size_t.
11321 (mark_object_loop_halt): Mark as externally visible.
11323 * xselect.c: Integer signedness and overflow fixes.
11324 (Fx_register_dnd_atom, x_handle_dnd_message):
11325 Use ptrdiff_t, not size_t, since we prefer signed.
11326 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11327 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11328 x_dnd_atoms_size and x_dnd_atoms_length.
11330 * doprnt.c: Prefer signed to unsigned when either works.
11332 * doprnt.c (doprnt):
11334 * xdisp.c (vmessage):
11335 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11336 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11337 prefer signed arithmetic to avoid comparison confusion.
11338 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11339 but is a bit tricky.
11341 Assume freestanding C89 headers, string.h, stdlib.h.
11342 * data.c, doprnt.c, floatfns.c, print.c:
11343 Include float.h unconditionally.
11344 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11345 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11346 * regex.c: Likewise for stddef.h, string.h.
11347 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11348 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11349 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11350 (STDC_HEADERS): Remove obsolete defines.
11351 * sysdep.c: Include limits.h unconditionally.
11353 Assume support for memcmp, memcpy, memmove, memset.
11354 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11355 * regex.c (memcmp, memcpy):
11356 Remove; we assume C89 now.
11358 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11359 (__malloc_safe_bcopy): Remove; no longer needed.
11361 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11362 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11363 well either way, and we prefer signed to unsigned.
11365 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11367 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11368 closes the connection while we're reading (bug#9182).
11370 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11372 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11373 are specified (Bug#9168).
11375 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11377 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11378 Found by GCC static checking and --with-wide-int on a 32-bit host.
11380 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11382 * xdisp.c (compute_display_string_pos): Fix logic of caching
11383 previous display string position. Initialize cached_prev_pos to
11384 -1. Fixes slow-down at the beginning of a buffer.
11386 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11388 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11389 for attrs[LFACE_FONTSET_INDEX].
11391 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11393 * xml.c (parse_region): Remove unused local
11394 that was recently introduced.
11396 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11398 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11399 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11401 * xdisp.c (move_it_in_display_line_to): Record the best matching
11402 position for TO_CHARPOS while scanning the line, and restore it on
11403 exit if none of the characters scanned was an exact match.
11404 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11405 when exact match is impossible due to invisible text, and the
11406 lines are truncated.
11408 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11410 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11413 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11415 Fix a significant slow-down of cursor motion with C-n, C-p,
11416 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11417 auto-repeat under bidi redisplay in fontified buffers.
11418 * xdisp.c (compute_stop_pos_backwards): New function.
11419 (next_element_from_buffer): Call compute_stop_pos_backwards to
11420 find a suitable prev_stop when we find ourselves before
11422 (reseat): Don't look for prev_stop, as that could mean a very long
11424 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11425 <cached_disp_overlay_modiff>: Cache for last found display string
11427 (compute_display_string_pos): Return the cached position if asked
11428 about the same buffer in the same area of character positions, and
11429 the buffer wasn't changed since the time the display string
11430 position was cached.
11432 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11434 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11435 is an integer, which is important for empty lines. (Bug#9149)
11437 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11439 * frame.c (Fmodify_frame_parameters): In tty case, update the
11440 default face if necessary (Bug#4238).
11442 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11444 * editfns.c (Fstring_to_char): No need to explain what a character
11445 is in the docstring (Bug#6576).
11447 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11449 * xml.c (parse_region): Make sure we always return a tree.
11451 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11453 * xml.c (parse_region): If a document contains only comments,
11456 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11458 * xml.c (make_dom): Return comments, too.
11460 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11463 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11464 and the surrounding thread.
11465 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11466 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11467 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11469 * s/openbsd.h (BROKEN_SIGIO): Define.
11470 * unexelf.c (unexec) [__OpenBSD__]:
11471 Don't update the .mdebug section of the Alpha COFF symbol table.
11473 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11475 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11478 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11480 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11481 This fixes some race conditions on the permissions of any newly
11484 * alloc.c (valid_pointer_p): Use pipe, not open.
11485 This fixes some permissions issues when debugging.
11487 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11488 If fchown fails to set both uid and gid, try to set just gid,
11489 as that is sometimes allowed. Adjust the file's mode to eliminate
11490 setuid or setgid bits that are inappropriate if fchown fails.
11492 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11494 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11495 to compare Lisp_Objects.
11496 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11497 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11498 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11500 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11502 * lread.c (read_integer): Unread even EOF character.
11503 (read1): Likewise. Properly record start position of symbol.
11505 * lread.c (read1): Read `#:' as empty uninterned symbol if no
11506 symbol character follows.
11508 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11510 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11511 This works around a problem with the previous change to Fcopy_file.
11512 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11513 and without this change, GCC might complain about discarding
11514 fchown's return value.
11516 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11518 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11520 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11522 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11524 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11526 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11527 it's used from the C level.
11529 * process.c: Use the same condition for POLL_FOR_INPUT in both
11530 keyboard.c and process.c (bug#1858).
11532 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11534 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11535 (Fgnutls_boot): Use it.
11537 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11539 * doc.c (Fsubstitute_command_keys): Revert last change.
11541 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11543 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11544 quotes the next character, and doesn't affect other longer
11545 sequences (bug#8935).
11547 * lread.c (syms_of_lread): Clarify that is isn't only
11548 `eval-buffer' and `eval-defun' that's affected by
11549 `lexical-binding' (bug#8460).
11551 2011-07-15 Eli Zaretskii <eliz@gnu.org>
11553 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11554 bidi redisplay when a line includes both an image and is truncated.
11556 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11558 Fix minor problems found by static checking.
11559 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11560 (elsz): Now a signed constant, not a size_t var. We prefer signed
11561 types to unsigned, to avoid integer comparison confusion. Without
11562 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
11563 "cannot optimize loop, the loop counter may overflow", a symptom
11565 * indent.c (Fvertical_motion): Mark locals as initialized.
11566 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
11568 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
11570 * search.c (Fre_search_backward): Mention `case-fold-search' in
11571 all the re_search_* functions (bug#8138).
11573 * keyboard.c (Fopen_dribble_file): Document when the file is

11578 * bidi.c (bidi_dump_cached_states): Fix format of displaying
11581 Support bidi reordering of display and overlay strings.

11584 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
11585 (reseat_to_string): Initialize bidi_it->string.s and
11586 bidi_it->string.schars.
11587 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
11588 NULL (avoids a crash in bidi_paragraph_init).
11589 Initialize itb.string.lstring.
11590 (init_iterator): Call bidi_init_it only of a valid
11591 buffer position was specified. Initialize paragraph_embedding to
11593 (reseat_to_string): Initialize the bidi iterator.
11594 (display_string): If we need to ignore text properties of
11595 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
11596 original value of -1 will not work with bidi.)
11597 (compute_display_string_pos): First arg is now struct
11598 `text_pos *'; all callers changed. Support display properties on
11600 (compute_display_string_end): Support display properties on Lisp
11602 (init_iterator, reseat_1, reseat_to_string): Initialize the
11603 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
11604 when iterating on a string not from display properties).
11605 (compute_display_string_pos, compute_display_string_end):
11606 Fix calculation of the object to scan. Fixes an error when using
11608 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
11609 base_level_stop; instead, set base_level_stop to BEGV.
11610 Fixes crashes in vertical-motion.
11611 (next_element_from_buffer): Improve commentary for when
11612 the iterator is before prev_stop.
11613 (init_iterator): Initialize bidi_p from the default value of
11614 bidi-display-reordering, not from buffer-local value. Use the
11615 buffer-local value only if initializing for buffer iteration.
11616 (handle_invisible_prop): Support invisible properties on strings
11617 that are being bidi-reordered.
11618 (set_iterator_to_next): Support bidi reordering of C strings and
11620 (next_element_from_string): Support bidi reordering of Lisp
11622 (handle_stop_backwards): Support Lisp strings as well.
11623 (display_string): Support display of R2L glyph rows.
11624 Use IT_STRING_CHARPOS when displaying from a Lisp string.
11625 (init_iterator): Don't initialize it->bidi_p for strings
11627 (reseat_to_string): Initialize it->bidi_p for strings here.
11628 (next_element_from_string, next_element_from_c_string)
11629 (next_element_from_buffer): Add xassert's for correspondence
11630 between IT's object being iterated and it->bidi_it.string
11632 (face_before_or_after_it_pos): Support bidi iteration.
11633 (next_element_from_c_string): Handle the case of the first string
11634 character that is not the first one in the visual order.
11635 (get_visually_first_element): New function, refactored from common
11636 parts of next_element_from_buffer, next_element_from_string, and
11637 next_element_from_c_string.
11638 (tool_bar_lines_needed, redisplay_tool_bar)
11639 (display_menu_bar): Force left-to-right direction. Add a FIXME
11640 comment for making that be controlled by a user option.
11641 (push_it, pop_it): Save and restore the state of the
11642 bidi iterator. Save and restore the bidi_p flag.
11643 (pop_it): Iterate out of display property for string iteration as
11645 (iterate_out_of_display_property): Support iteration over strings.
11646 (handle_single_display_spec): Set up it->bidi_it for iteration
11647 over a display string, and call bidi_init_it.
11648 (handle_single_display_spec, next_overlay_string)
11649 (get_overlay_strings_1, push_display_prop): Set up the bidi
11650 iterator for displaying display or overlay strings.
11651 (forward_to_next_line_start): Don't use the shortcut if
11653 (back_to_previous_visible_line_start): If handle_display_prop
11654 pushed the iterator stack, restore the internal state of the bidi
11655 iterator by calling bidi_pop_it same number of times.
11656 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
11657 and we are bidi-iterating, don't decrement the iterator position;
11658 instead, set the first_elt flag in the bidi iterator, to produce
11660 (reseat_1): Remove redundant setting of string_from_display_prop_p.
11661 (push_display_prop): xassert that we are iterating a buffer.
11662 (push_it, pop_it): Save and restore paragraph_embedding member.
11663 (handle_single_display_spec, next_overlay_string)
11664 (get_overlay_strings_1, reseat_1, reseat_to_string)
11665 (push_display_prop): Set up the `unibyte' member of bidi_it.string
11666 correctly. Don't assume unibyte strings are not bidi-reordered.
11667 (compute_display_string_pos)
11668 (compute_display_string_end): Fix handling the case of C string.
11669 (push_it, pop_it): Save and restore from_disp_prop_p.
11670 (handle_single_display_spec, push_display_prop): Set the
11671 from_disp_prop_p flag.
11672 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
11673 (pop_it): Call iterate_out_of_display_property only if we are
11674 popping after iteration over a string that came from a display
11675 property. Fix a typo in popping stretch info. Add an assertion
11676 for verifying that the iterator position is in sync with the bidi
11678 (handle_single_display_spec, get_overlay_strings_1)
11679 (push_display_prop): Fix initialization of paragraph direction for
11680 string when that of the parent object is not yet determined.
11681 (reseat_1): Call bidi_init_it to resync the bidi
11682 iterator with IT's position. (Bug#7616)
11683 (find_row_edges): If ROW->start.pos gives position
11684 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
11685 (handle_stop, back_to_previous_visible_line_start, reseat_1):
11686 Reset the from_disp_prop_p flag.
11687 (SAVE_IT, RESTORE_IT): New macros.
11688 (pos_visible_p, face_before_or_after_it_pos)
11689 (back_to_previous_visible_line_start)
11690 (move_it_in_display_line_to, move_it_in_display_line)
11691 (move_it_to, move_it_vertically_backward, move_it_by_lines)
11692 (try_scrolling, redisplay_window, display_line): Use them when
11693 saving a temporary copy of the iterator and restoring it back.
11694 (back_to_previous_visible_line_start, reseat_1)
11695 (init_iterator): Empty the bidi cache "stack".

12134 Prefer signed to unsigned, since the signedness doesn't matter and
12135 in general we prefer signed. When given a limit, use a
12136 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12137 latter isn't right if USE_2_TAGS_FOR_INTS.
12138 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12139 not 0..VALMASK. Don't discard "excess" bits that random () returns.
12141 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
12143 * textprop.c (text_property_stickiness):
12144 Obey Vtext_property_default_nonsticky.
12145 (syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.

12151 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
12152 This is more efficient than Ffile_directory_p and avoids a minor race.
12154 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
12156 * buffer.c (Foverlay_put): Say what the return value is
12159 * fileio.c (barf_or_query_if_file_exists): Check first if the file
12160 is a directory before asking whether to use the file name
12162 (barf_or_query_if_file_exists): Make the "File is a directory"
12163 error be more correct.
12165 * fns.c (Frequire): Remove the mention of the .gz files, since
12166 that's installation-specific, but keep the mention of
12167 `get-load-suffixes'.
12169 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
12171 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

12176 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
12177 (syms_of_gnutls): Remove duplicate DEFSYM for
12178 Qgnutls_bootprop_verify_hostname_error, an error for
12179 Qgnutls_bootprop_verify_error (which is no longer used).
12181 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
12182 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
12183 Also (re)move comments that are misplaced or no longer relevant.

12284 * eval.c (struct backtrace): Simplify and port the data structure.
12285 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12286 signed bit field, as this assumption is not portable and it makes
12287 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12288 "char debug_on_exit : 1" as this is not portable either; instead,
12289 use the portable "unsigned int debug_on_exit : 1". Remove unused
12290 member evalargs. Remove obsolete comments about cc bombing out.
12292 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
12294 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

12362 (emacs_fixed_get_preferred_height): Use min_width/height from
12363 frames size_hint to set minimum and natural (Bug#8919).
12364 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
12365 and use min_width/height from frames size_hint to set
12366 min_width/height (Bug#8919).
12368 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.

12386 Use gnulib's dup2 module instead of rolling our own.
12387 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

12458 * print.c (printchar, strout): Check for string overflow.
12459 (PRINTPREPARE, printchar, strout):
12460 Don't set size unless allocation succeeds.
12462 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
12463 for sizes. Check for string overflow more accurately.

12467 * keyboard.h (struct keyboard.kbd_macro_bufsize):
12468 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

12477 (read_integer): Radix is now EMACS_INT, not int,
12478 to improve quality of diagnostics for out-of-range radices.
12479 Calculate buffer size correctly for out-of-range radices.
12480 (read1): Check for integer overflow in radices, and in
12481 read-circle numbers.
12482 (read_escape): Avoid int overflow.
12483 (Fload, openp, read_buffer_size, read1)
12484 (substitute_object_recurse, read_vector, read_list, map_obarray):

12507 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
12508 The following patches are for when GLYPH_DEBUG && !XASSERT.
12509 * dispextern.h (trace_redisplay_p, dump_glyph_string):
12510 * dispnew.c (flush_stdout):
12511 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
12512 Mark as externally visible.
12513 * dispnew.c (check_window_matrix_pointers): Now static.
12514 * dispnew.c (window_to_frame_vpos):
12515 * xfns.c (unwind_create_frame):

12524 (debug_method_add): Use va_list and vsprintf rather than relying
12525 on undefined behavior with wrong number of arguments.
12526 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12527 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12528 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12529 since we're not interested in debugging glyphs with old libraries.
12530 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12531 GCC 4.6.0's static checking.
12533 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

12565 (Fnext_overlay_change, Fprevious_overlay_change)
12566 (mouse_face_overlay_overlaps, Foverlays_in):
12567 Use ptrdiff_t, not int, for sizes.
12568 (overlays_at, overlays_in): Check for size-calculation overflow.
12570 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
12572 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
12573 (x_session_initialize): Do not assume string length fits in int.
12575 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
12576 This is unlikely, but can occur if DPI is outlandish.
12578 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
12579 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
12581 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
12582 * xrdb.c (magic_file_p, search_magic_path):
12583 Omit last arg SUFFIX; it was always 0. All callers changed.
12584 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
12586 * xfont.c (xfont_match): Avoid need for strlen.
12588 * xfns.c: Don't assume strlen fits in int.
12589 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
12591 * xdisp.c (message_log_check_duplicate): Return intmax_t,
12592 not unsigned long, as we prefer signed integers. All callers changed.
12593 Detect integer overflow in repeat count.
12594 (message_dolog): Don't assume print length fits in 39 bytes.
12595 (display_mode_element): Don't assume strlen fits in int.
12597 * termcap.c: Don't assume sizes fit in int and never overflow.
12598 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
12599 (gobble_line): Check for size-calculation overflow.
12601 * minibuf.c (Fread_buffer):
12602 * lread.c (intern, intern_c_string):
12603 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
12604 Don't assume string length fits in int.
12606 * keyboard.c (parse_tool_bar_item):
12607 * gtkutil.c (style_changed_cb): Avoid need for strlen.
12609 * font.c: Don't assume string length fits in int.
12610 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
12611 Use ptrdiff_t, not int.
12612 (font_intern_prop): Don't assume string length fits in int.
12613 Don't assume integer property fits in fixnum.
12614 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
12616 * filelock.c: Fix some buffer overrun and integer overflow issues.
12617 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
12618 Reformulate so as not to need the command string.
12619 Invoke gzip -cd rather than gunzip, as it's more portable.
12620 (lock_info_type, lock_file_1, lock_file):
12621 Don't assume pid_t and time_t fit in unsigned long.
12622 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
12623 (current_lock_owner): Prefer signed type for sizes.
12624 Use memcpy, not strncpy, where memcpy is what is really wanted.
12625 Don't assume (via atoi) that time_t and pid_t fit in int.
12626 Check for time_t and/or pid_t out of range, e.g., via a network share.
12627 Don't alloca where an auto var works fine.
12629 * fileio.c: Fix some integer overflow issues.
12630 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
12631 Don't assume string length fits in int.
12632 (directory_file_name): Don't assume string length fits in long.
12633 (make_temp_name): Don't assume pid fits in int, or that its print
12634 length is less than 20.
12636 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
12638 * coding.c (make_subsidiaries): Don't assume string length fits in int.
12640 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
12642 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
12643 We prefer signed integers, even for size calculations.
12645 * emacs.c: Don't assume string length fits in 'int'.
12646 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
12647 (main): Don't invoke strlen when not needed.
12649 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
12650 (XD_DEBUG_MESSAGE): Don't waste a byte.
12652 * callproc.c (getenv_internal_1, getenv_internal)
12653 (Fgetenv_internal):
12654 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
12656 * lread.c (invalid_syntax): Omit length argument.
12657 All uses changed. This doesn't fix a bug, but it simplifies the
12658 code away from its former Hollerith-constant appearance, and it's
12659 one less 'int' to worry about when looking at integer-overflow issues.
12660 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
12662 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
12663 This didn't break anything, but it didn't help either.
12664 It's confusing to put a bogus integer in a place where the actual
12665 value does not matter.
12666 (LIST_END_P): Remove unused macro and its bogus comment.
12667 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
12669 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
12670 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
12672 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
12673 We prefer signed types, and the value cannot exceed the EMACS_INT
12674 range anyway (because otherwise the length would not be representable).
12675 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
12676 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
12677 This avoids a GCC warning when WIDE_EMACS_INT.
12679 * indent.c (sane_tab_width): New function.
12680 (current_column, scan_for_column, Findent_to, position_indentation)
12681 (compute_motion): Use it. This is just for clarity.
12682 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
12684 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
12686 * lisp.h (lint_assume): New macro.
12687 * composite.c (composition_gstring_put_cache):
12688 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
12690 * editfns.c, insdel.c:
12691 Omit unnecessary forward decls, to simplify future changes.
12693 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
12695 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
12697 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
12698 Use much-faster test for byte-length change.
12699 Don't assume string byte-length fits in 'int'.
12700 Check that character arg fits in 'int'.
12701 (mapcar1): Declare byte as byte, for clarity.
12703 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
12705 * fns.c (concat): Catch string overflow earlier.
12706 Do not rely on integer wraparound.
12708 * dispextern.h (struct it.overlay_strings_charpos)
12709 (struct it.selective): Now EMACS_INT, not int.
12710 * xdisp.c (forward_to_next_line_start)
12711 (back_to_previous_visible_line_start)
12712 (reseat_at_next_visible_line_start, next_element_from_buffer):
12713 Don't arbitrarily truncate the value of 'selective' to int.
12715 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
12717 * composite.c: Don't truncate sizes to 'int'.
12718 (composition_gstring_p, composition_reseat_it)
12719 (composition_adjust_point): Use EMACS_INT, not int.
12720 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
12721 not EMACS_UINT, for indexes.
12723 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
12725 * buffer.c: Include <verify.h>.
12726 (struct sortvec.priority, struct sortstr.priority):
12727 Now EMACS_INT, not int.
12728 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
12729 (struct sortstr.size, record_overlay_string)
12730 (struct sortstrlist.size, struct sortlist.used):
12731 Don't truncate size to int.
12732 (record_overlay_string): Check for size-calculation overflow.
12733 (init_buffer_once): Check at compile-time, not run-time.
12735 2011-06-22 Jim Meyering <meyering@redhat.com>
12737 Don't leak an XBM-image-sized buffer
12738 * image.c (xbm_load): Free the image buffer after using it.
12740 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
12743 * composite.c (find_automatic_composition): Omit needless 'return 0;'
12744 that Sun C diagnosed.
12745 * fns.c (secure_hash): Fix pointer signedness issue.
12746 * intervals.c (static_offset_intervals): New function.
12747 (offset_intervals): Use it.
12749 2011-06-21 Leo Liu <sdl.web@gmail.com>
12752 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
12755 * fns.c (secure_hash): Rename from crypto_hash_function and change
12756 the first arg to accept symbols.
12757 (Fsecure_hash): New primitive.
12758 (syms_of_fns): New symbols.
12760 2011-06-20 Deniz Dogan <deniz@dogan.se>
12762 * process.c (Fset_process_buffer): Clarify return value in
12765 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
12767 * dispnew.c (add_window_display_history): Use BVAR.
12769 * xdisp.c (debug_method_add): Use BVAR.
12770 (check_window_end, dump_glyph_matrix, dump_glyph)
12771 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
12773 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
12776 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
12777 check till after the cache is created in init_frame_faces.
12779 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
12781 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
12783 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
12785 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
12786 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
12787 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
12789 Improve buffer-overflow checking (Bug#8873).
12790 * fileio.c (Finsert_file_contents):
12791 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
12792 Remove the old (too-loose) buffer overflow checks.
12793 They weren't needed, since make_gap checks for buffer overflow.
12794 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
12795 The old code merely checked for Emacs fixnum overflow, and relied
12796 on undefined (wraparound) behavior. The new code avoids undefined
12797 behavior, and also checks for ptrdiff_t and/or size_t overflow.
12799 * editfns.c (Finsert_char): Don't dump core with very negative counts.
12800 Tune. Don't use wider integers than needed. Don't use alloca.
12801 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
12803 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
12805 * insdel.c, lisp.h (buffer_overflow): New function.
12806 (insert_from_buffer_1, replace_range, replace_range_2):
12807 * insdel.c (make_gap_larger):
12808 * editfns.c (Finsert_char):
12809 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
12811 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
12813 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
12815 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
12817 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
12818 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
12820 * fileio.c: Don't assume EMACS_INT fits in off_t.
12821 (emacs_lseek): New static function.
12822 (Finsert_file_contents, Fwrite_region): Use it.
12823 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
12825 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
12827 * fns.c: Don't overflow int when computing a list length.
12828 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
12829 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
12830 truncation on 64-bit hosts. Check for QUIT every
12831 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
12832 faster and is responsive enough.
12833 (Flength): Report an error instead of overflowing an integer.
12834 (Fsafe_length): Return a float if the value is not representable
12835 as a fixnum. This shouldn't happen except in contrived situations.
12836 (Fnthcdr, Fsort): Don't assume list length fits in int.
12837 (Fcopy_sequence): Don't assume vector length fits in int.
12839 * alloc.c: Check that resized vectors' lengths fit in fixnums.
12840 (header_size, word_size): New constants.
12841 (allocate_vectorlike): Don't check size overflow here.
12842 (allocate_vector): Check it here instead, since this is the only
12843 caller of allocate_vectorlike that could cause overflow.
12844 Check that the new vector's length is representable as a fixnum.
12846 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
12847 The previous code was bogus. For example, next_almost_prime (32)
12848 returned 39, which is undesirable as it is a multiple of 3; and
12849 next_almost_prime (24) returned 25, which is a multiple of 5 so
12850 why was the code bothering to check for multiples of 7?
12852 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
12854 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
12856 Variadic C functions now count arguments with ptrdiff_t.
12857 This partly undoes my 2011-03-30 change, which replaced int with size_t.
12858 Back then I didn't know that the Emacs coding style prefers signed int.
12859 Also, in the meantime I found a few more instances where arguments
12860 were being counted with int, which may truncate counts on 64-bit
12861 machines, or EMACS_INT, which may be unnecessarily wide.
12862 * lisp.h (struct Lisp_Subr.function.aMANY)
12863 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
12864 Arg counts are now ptrdiff_t, not size_t.
12865 All variadic functions and their callers changed accordingly.
12866 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
12867 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
12868 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
12869 * callint.c (Fcall_interactively): Check arg count for overflow,
12870 to avoid potential buffer overrun. Use signed char, not 'int',
12871 for 'varies' array, so that we needn't bother to check its size
12872 calculation for overflow.
12873 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
12874 * eval.c (apply_lambda):
12875 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
12876 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
12877 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
12879 * callint.c (Fcall_interactively): Don't use index var as event count.
12881 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
12882 * mem-limits.h (SIZE): Remove; no longer used.
12884 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
12886 Remove unnecessary casts.
12887 * xterm.c (x_term_init):
12888 * xfns.c (x_set_border_pixel):
12889 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
12890 These aren't needed now that we assume ANSI C.
12892 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
12893 It's more likely to cause problems (due to unsigned overflow)
12896 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
12898 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
12900 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
12902 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
12904 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
12906 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
12908 GLYPH_CODE_FACE returns EMACS_INT, not int.
12909 * dispextern.h (merge_faces):
12910 * xfaces.c (merge_faces):
12911 * xdisp.c (get_next_display_element, next_element_from_display_vector):
12912 Don't assume EMACS_INT fits in int.
12914 * character.h (CHAR_VALID_P): Remove unused parameter.
12915 * fontset.c, lisp.h, xdisp.c: All uses changed.
12917 * editfns.c (Ftranslate_region_internal): Omit redundant test.
12919 * fns.c (concat): Minor tuning based on overflow analysis.
12920 This doesn't fix any bugs. Use int to hold character, instead
12921 of constantly refetching from Emacs object. Use XFASTINT, not
12922 XINT, for value known to be a character. Don't bother comparing
12923 a single byte to 0400, as it's always less.
12925 * floatfns.c (Fexpt):
12926 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
12928 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
12931 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
12933 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
12934 Without this fix, on a 64-bit host (aset S 0 4294967386) would
12935 incorrectly succeed when S was a string, because 4294967386 was
12936 truncated before it was used.
12938 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
12939 Otherwise, an out-of-range integer could cause undefined behavior
12942 * composite.c: Use int, not EMACS_INT, for characters.
12943 (fill_gstring_body, composition_compute_stop_pos): Use int, not
12944 EMACS_INT, for values that are known to be in character range.
12945 This doesn't fix any bugs but is the usual style inside Emacs and
12946 may generate better code on 32-bit machines.
12948 Make sure a 64-bit char is never passed to ENCODE_CHAR.
12949 This is for reasons similar to the recent CHAR_STRING fix.
12950 * charset.c (Fencode_char): Check that character arg is actually
12951 a character. Pass an int to ENCODE_CHAR.
12952 * charset.h (ENCODE_CHAR): Verify that the character argument is no
12953 wider than 'int', as a compile-time check to prevent future regressions
12956 * character.c (char_string): Remove unnecessary casts.
12958 Make sure a 64-bit char is never passed to CHAR_STRING.
12959 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
12960 by silently ignoring the top 32 bits, allowing some values
12961 that were far too large to be valid characters.
12962 * character.h: Include <verify.h>.
12963 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
12964 arguments are no wider than unsigned, as a compile-time check
12965 to prevent future regressions in this area.
12967 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
12968 (Fsubst_char_in_region):
12970 * xdisp.c (decode_mode_spec_coding):
12971 Adjust to CHAR_STRING's new requirement.
12972 * editfns.c (Finsert_char, Fsubst_char_in_region):
12973 * fns.c (concat): Check that character args are actually
12974 characters. Without this test, these functions did the wrong
12975 thing with wildly out-of-range values on 64-bit hosts.
12977 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
12978 These casts should not be needed on 32-bit hosts, either.
12979 * keyboard.c (read_char):
12980 * lread.c (Fload): Remove casts to unsigned.
12982 * lisp.h (UNSIGNED_CMP): New macro.
12983 This fixes comparison bugs on 64-bit hosts.
12984 (ASCII_CHAR_P): Use it.
12985 * casefiddle.c (casify_object):
12986 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
12987 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
12988 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
12989 * dispextern.h (FACE_FROM_ID):
12990 * keyboard.c (read_char): Use UNSIGNED_CMP.
12992 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
12993 not to EMACS_INT, to avoid GCC warning.
12995 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
12997 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
12998 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
12999 isn't needed on 32-bit machines.
13001 * buffer.c (Fgenerate_new_buffer_name):
13002 Use EMACS_INT for count, not int.
13003 (advance_to_char_boundary): Return EMACS_INT, not int.
13005 * data.c (Qcompiled_function): Now static.
13007 * window.c (window_body_lines): Now static.
13009 * image.c (gif_load): Rename local to avoid shadowing.
13011 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
13012 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
13013 * alloc.c (make_save_value): Integer argument is now of type
13014 ptrdiff_t, not int.
13015 (mark_object): Use ptrdiff_t, not int.
13016 * lisp.h (pD): New macro.
13017 * print.c (print_object): Use it.

13049 (allocate_string_data): Check for string overflow. This catches
13050 some instances we weren't catching before. Also, it catches
13051 size_t overflow on (unusual) hosts where SIZE_MAX <= min
13052 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
13053 and ptrdiff_t and EMACS_INT are both 64 bits.

13561 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
13562 Do not assume that spare memory exists; that assumption is valid
13563 only if SYSTEM_MALLOC.
13564 (LARGE_REQUEST): New macro, so that the issue of large requests
13565 is separated from the issue of spare memory.

13634 instead of using explicit *_CHAR codes.
13635 (bidi_resolve_explicit, bidi_resolve_weak):

13644 (bidi_level_of_next_char): Don't try to lookup the cache for the
13645 next/previous character if nothing is cached there yet, or if we
13646 were just reseat()'ed to a new position.
13648 * xdisp.c (set_cursor_from_row): Set start and stop points
13649 according to the row's direction when priming the loop that looks
13650 for the glyph on which to display cursor.

13652 (display_prop_intangible_p): Reimplement to call
13653 handle_display_spec instead of single_display_spec_intangible_p.
13654 Accept 3 additional arguments needed by handle_display_spec.
13655 This fixes incorrect cursor motion across display property with complex

13663 (compute_display_string_pos): Accept additional argument
13664 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
13665 value of a `display' property is a "replacing spec".
13666 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
13667 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
13668 the display property, but just return a value indicating whether
13669 the display property will replace the characters it covers.
13670 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
13671 frame_window_p members of struct bidi_it.
13672 (compute_display_string_pos, compute_display_string_end):

13695 All callers changed. (Bug#8762)
13697 * gnutls.c: Use Emacs's memory allocators.
13698 Without this change, the gnutls library would invoke malloc etc.
13699 directly, which causes problems on non-SYNC_INPUT hosts, and which
13700 runs afoul of improving memory_full behavior. (Bug#8761)
13701 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
13702 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
13703 xfree instead of the default malloc, realloc, free.
13704 (Fgnutls_boot): No need to check for memory allocation failure,
13705 since xmalloc does that for us.
13707 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
13708 * category.c (hash_get_category_set):

13727 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
13728 for hashes and hash indexes, instead of 'unsigned' and 'int'.
13729 * alloc.c (allocate_vectorlike):
13730 Check for overflow in vector size calculations.
13731 * ccl.c (ccl_driver):
13732 Check for overflow when converting EMACS_INT to int.

13734 need to be updated by these changes.
13735 * fns.c (make_hash_table, maybe_resize_hash_table):
13736 Check for integer overflow with large hash tables.
13737 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
13738 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
13739 (SXHASH_REDUCE): New macro.
13740 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
13741 Use it instead of discarding useful hash info with large hash values.
13742 (sxhash_float): New function.
13743 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
13744 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
13745 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
13746 Rewrite to use FIXNUM_BITS, as this simplifies things.
13747 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
13748 Adjust signatures to match updated version of code.
13749 (consing_since_gc): Now EMACS_INT, since a single hash table can
13750 use more than INT_MAX bytes.

13799 Make it possible to run ./temacs.
13801 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
13802 syms_of_callproc does the same thing. Remove test for

13863 * fns.c (to_uchar): Define.
13864 (crypto_hash_function): Use it to convert some newly-signed
13865 variables to unsigned, to avoid sign-extension bugs. For example,
13866 without this change, (md5 "truc") would evaluate to
13867 45723a2aff78ff4fff7fff1114760e62 rather than the expected
13868 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in

13884 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13885 Use XFASTINT rather than XUINT when numbers are nonnegative.
13886 (xd_append_arg, Fdbus_method_return_internal):
13887 (Fdbus_method_error_internal): Likewise. Also, for unsigned
13888 arguments, check that Lisp number is nonnegative, rather than
13889 silently wrapping negative numbers around. (Bug#8722)
13890 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
13893 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
13895 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
13897 ccl: Add integer overflow checks.
13898 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
13899 (IN_INT_RANGE): New macros.
13900 (ccl_driver): Use them to check for integer overflow when
13901 decoding a CCL program. Many of the new checks are whether XINT (x)
13902 fits in int; it doesn't always, on 64-bit hosts. The new version
13903 doesn't catch all possible integer overflows, but it's an
13904 improvement. (Bug#8719)
13906 * alloc.c (make_event_array): Use XINT, not XUINT.
13907 There's no need for unsigned here.
13909 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
13910 This follows up to the 2011-05-06 change that substituted uintptr_t
13911 for EMACS_INT. This case wasn't caught back then.
13913 Rework Fformat to avoid integer overflow issues.
13914 * editfns.c: Include <float.h> unconditionally, as it's everywhere
13915 now (part of C89). Include <verify.h>.
13916 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
13917 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
13918 (Fformat): Avoid the prepass trying to compute sizes; it was only
13919 approximate and thus did not catch overflow reliably. Instead, walk
13920 through the format just once, formatting and computing sizes as we go,
13921 checking for integer overflow at every step, and allocating a larger
13922 buffer as needed. Keep track separately whether the format is
13923 multibyte. Keep only the most-recently calculated precision, rather
13924 than them all. Record whether each argument has been converted to
13925 string. Use EMACS_INT, not int, for byte and char and arg counts.
13926 Support field widths and precisions larger than INT_MAX. Avoid
13927 sprintf's undefined behavior with conversion specifications such as %#d
13928 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
13929 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
13930 formatting out-of-range floating point numbers with int
13931 formats. (Bug#8668)
13933 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
13935 * data.c: Avoid integer truncation in expressions involving floats.
13936 * data.c: Include <intprops.h>.
13937 (arith_driver): When there's an integer overflow in an expression
13938 involving floating point, convert the integers to floating point
13939 so that the resulting value does not suffer from catastrophic
13940 integer truncation. For example, on a 64-bit host (* 4
13941 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
13942 Do not rely on undefined behavior after integer overflow.
13944 merge count_size_as_multibyte, parse_str_to_multibyte
13945 * character.c, character.h (count_size_as_multibyte):
13946 Rename from parse_str_to_multibyte; all uses changed.
13947 Check for integer overflow.
13948 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
13949 since it's now a duplicate of the other. This is more of
13950 a character than a buffer op, so better that it's in character.c.
13951 * fns.c, print.c: Adjust to above changes.
13953 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
13955 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
13957 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13959 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13960 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
13961 (x_clipboard_manager_save): Now static.
13962 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
13964 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13965 (crypto_hash_function): Now static.
13966 Fix pointer signedness problems. Avoid unnecessary initializations.
13968 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
13970 * termhooks.h (Vselection_alist): Make it terminal-local.
13972 * terminal.c (create_terminal): Initialize it.
13974 * xselect.c: Support for clipboard managers.
13975 (Vselection_alist): Move to termhooks.h as terminal-local var.
13976 (LOCAL_SELECTION): New macro.
13977 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
13978 (symbol_to_x_atom): Remove gratuitous arg.
13979 (x_handle_selection_request, lisp_data_to_selection_data)
13980 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
13981 (x_own_selection, x_get_local_selection, x_convert_selection):
13982 New arg, specifying work frame. Use terminal-local Vselection_alist.
13983 (some_frame_on_display): Delete unused function.
13984 (Fx_own_selection_internal, Fx_get_selection_internal)
13985 (Fx_disown_selection_internal, Fx_selection_owner_p)
13986 (Fx_selection_exists_p): New optional frame arg.
13987 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
13988 (x_handle_selection_clear): Don't treat other terminals with the
13989 same keyboard specially. Use the terminal-local Vselection_alist.
13990 (x_clear_frame_selections): Use Frun_hook_with_args.
13992 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
13994 * xterm.h: Add support for those atoms.
13996 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
13998 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
13999 (converted_selections, conversion_fail_tag): New global variables.
14000 (x_selection_request_lisp_error): Free the above.
14001 (x_get_local_selection): Remove unnecessary code.
14002 (x_reply_selection_request): Args changed; handle arbitrary array
14003 of converted selections stored in converted_selections.
14004 Separate the XChangeProperty and SelectionNotify steps.
14005 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14006 (x_convert_selection): New function.
14007 (x_handle_selection_event): Simplify.
14008 (x_get_foreign_selection): Don't ignore incoming requests while
14009 waiting for an answer; this will fail when we implement
14010 SAVE_TARGETS, and seems unnecessary anyway.
14011 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14012 (Vx_sent_selection_functions): Doc fix.
14014 2011-05-26 Leo Liu <sdl.web@gmail.com>
14016 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14018 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14020 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14022 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14023 for fringe update if it has periodic bitmap.
14024 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14025 and fringe_bitmap_periodic_p.
14027 * fringe.c (get_fringe_bitmap_data): New function.
14028 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14029 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14030 row. Mark glyph row for fringe update if periodicity changed.
14032 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14033 for fringe update unless it has periodic bitmap.
14035 2011-05-25 Kenichi Handa <handa@m17n.org>
14037 * xdisp.c (get_next_display_element): Set correct it->face_id for
14038 a static composition.
14040 2011-05-24 Leo Liu <sdl.web@gmail.com>
14043 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
14045 * fns.c (crypto_hash_function, Fsha1): New function.
14046 (Fmd5): Use crypto_hash_function.
14047 (syms_of_fns): Add Ssha1.
14049 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14051 * gnutls.c: Remove unused macros.
14052 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14053 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14054 Remove macros that are defined and never used.
14055 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14057 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14059 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14060 (Fx_get_selection_internal): Minor cleanup.
14061 (Fx_own_selection_internal): Rename arguments for consistency with
14064 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14066 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
14068 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14070 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
14072 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14074 * dispnew.c (scrolling_window): Don't exclude the case that the
14075 last enabled row in the desired matrix touches the bottom boundary.
14077 2011-05-21 Glenn Morris <rgm@gnu.org>
14079 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
14080 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
14081 and add some more files.
14083 2011-05-20 Eli Zaretskii <eliz@gnu.org>
14085 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
14086 report_file_error introduced by the change from 2011-05-07.
14088 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14090 * systime.h (Time): Define only if emacs is defined.
14091 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14092 where the include path doesn't have X11/X.h by default. See
14093 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14095 2011-05-20 Kenichi Handa <handa@m17n.org>
14097 * composite.c (find_automatic_composition): Fix previous change.
14099 2011-05-20 Glenn Morris <rgm@gnu.org>
14101 * lisp.mk: New file, split from Makefile.in.
14102 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14103 (shortlisp): Remove.
14104 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14106 2011-05-19 Glenn Morris <rgm@gnu.org>
14108 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14109 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14110 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14111 (lisp): Set the order to that of loadup.el.
14112 (shortlisp): Make it a copy of $lisp.
14113 (SOME_MACHINE_LISP): Remove.
14114 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14115 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14117 2011-05-18 Kenichi Handa <handa@m17n.org>
14119 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14120 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14121 (find_automatic_composition): Mostly rewrite for efficiency.
14123 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14125 * makefile.w32-in: Update dependencies.
14127 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14129 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14130 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14132 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14134 Fix some integer overflow issues, such as string length overflow.
14136 * insdel.c (count_size_as_multibyte): Check for string overflow.
14138 * character.c (lisp_string_width): Check for string overflow.
14139 Use EMACS_INT, not int, for string indexes and lengths; in
14140 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14141 the resulting string length overflows an EMACS_INT; instead,
14142 report a string overflow if no precision given. When checking for
14143 precision exhaustion, use a check that cannot possibly have
14144 integer overflow. (Bug#8675)
14145 * character.h (lisp_string_width): Adjust to new signature.
14147 * alloc.c (string_overflow): New function.
14148 (Fmake_string): Use it. This doesn't change behavior, but saves
14149 a few bytes and will simplify future changes.
14150 * character.c (string_escape_byte8): Likewise.
14151 * lisp.h (string_overflow): New decl.
14153 Fixups, following up to the user-interface timestamp change.
14154 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14155 for UI timestamps, instead of unsigned long.
14156 * msdos.c (mouse_get_pos): Likewise.
14157 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14158 * w32gui.h (Time): Define by including "systime.h" rather than by
14159 declaring it ourselves. (Bug#8664)
14161 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14162 * image.c (clear_image_cache): Likewise.
14164 * term.c (term_mouse_position): Don't assume time_t wraparound.
14166 Be more systematic about user-interface timestamps.
14167 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14168 and sometimes 'EMACS_UINT', to represent these timestamps.
14169 This change causes it to use 'Time' uniformly, as that's what X uses.
14170 This makes the code easier to follow, and makes it easier to catch
14171 integer overflow bugs such as Bug#8664.
14172 * frame.c (Fmouse_position, Fmouse_pixel_position):
14173 Use Time, not unsigned long, for user-interface timestamps.
14174 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14175 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14176 * keyboard.h (last_event_timestamp): Likewise.
14177 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14178 * menu.h (xmenu_show): Likewise.
14179 * term.c (term_mouse_position): Likewise.
14180 * termhooks.h (struct input_event.timestamp): Likewise.
14181 (struct terminal.mouse_position_hook): Likewise.
14182 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14183 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14184 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14185 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14186 what it was before.
14187 * menu.h, termhooks.h: Include "systime.h", for Time.
14189 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14190 Don't assume that the difference between two unsigned long values
14191 can fit into an integer. At this point, we know button_down_time
14192 <= event->timestamp, so the difference must be nonnegative, so
14193 there's no need to cast the result if double-click-time is
14194 nonnegative, as it should be; check that it's nonnegative, just in
14195 case. This bug is triggered when events are more than 2**31 ms
14196 apart (about 25 days). (Bug#8664)
14198 * xselect.c (last_event_timestamp): Remove duplicate decl.
14199 (x_own_selection): Remove needless cast to unsigned long.
14201 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14202 that always fit in int. Use a sentinel instead of a counter, to
14203 avoid a temp and to allay GCC's concerns about possible int overflow.
14204 * frame.h (struct frame): Use int for menu_bar_items_used
14205 instead of EMACS_INT, since it always fits in int.
14207 * menu.c (grow_menu_items): Check for int overflow.
14209 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14211 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14212 Before, the code was not consistent. These values cannot exceed
14213 2**31 - 1 so there's no need to make them unsigned.
14214 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14215 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14216 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14218 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14220 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14221 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14222 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14223 presumably because the widths might not match.
14225 * window.c (size_window): Avoid needless test at loop start.
14227 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14229 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14231 2011-05-12 Drew Adams <drew.adams@oracle.com>
14233 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14235 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14237 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14238 `width' to `bar_area_x' and `bar_area_width', respectively.
14239 (x_scroll_run): Take account of fringe background extension.
14241 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14242 Rename local vars `left' and `width' to `bar_area_x' and
14243 `bar_area_width', respectively.
14244 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14245 background extension.
14247 2011-05-10 Jim Meyering <meyering@redhat.com>
14249 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14251 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14253 * image.c (Finit_image_library): Return t for built-in image types,
14254 like pbm and xbm. (Bug#8640)
14256 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14258 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14260 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14262 * w32console.c (Fset_screen_color): Doc fix.
14263 (Fget_screen_color): New function.
14264 (syms_of_ntterm): Defsubr it.
14266 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14267 unlink the temporary file if Fcall_process didn't create it in the
14269 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14270 child process will be redirected to a file specified with `:file'.
14271 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14272 cue to call_process_cleanup not to close that handle.
14274 2011-05-07 Ben Key <bkey76@gmail.com>
14276 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14277 one of two shell specific rules, either bootstrap-temacs-CMD or
14278 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14279 to the previous implementation of the bootstrap-temacs rule.
14280 The bootstrap-temacs-CMD rule is similar to the previous
14281 implementation of the bootstrap-temacs rule except that it
14282 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14285 These changes, along with some changes to nt/configure.bat,
14286 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14287 earlier fix to add support for --cflags and --ldflags options
14288 that include quotes so that it works whether make uses cmd or
14291 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14293 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14294 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14296 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14297 a string. Handle both cases.
14298 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14299 (Fdbus_register_method): Use Qinvalid_function.
14301 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14303 * makefile.w32-in: Update dependencies.
14304 (LISP_H): Add inttypes.h and stdin.h.
14305 (PROCESS_H): Add unistd.h.
14307 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14309 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14310 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14312 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14314 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14316 * term.c (vfatal): Remove stray call to va_end.
14317 It's not needed and the C Standard doesn't allow it here anyway.
14319 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14320 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14322 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14325 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14327 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14329 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14331 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14333 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14335 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14336 * charset.c (Fdefine_charset_internal): Don't initialize
14337 charset.code_space[15]. The value was garbage, on hosts with
14338 32-bit int (Bug#8600).
14340 * lread.c (read_integer): Be more consistent with string-to-number.
14341 Use string_to_number to do the actual conversion; this avoids
14342 rounding errors and fixes some other screwups. Without this fix,
14343 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14344 (digit_to_number): Move earlier, for benefit of read_integer.
14345 Return -1 if the digit is out of range for the base, -2 if it is
14346 not a digit in any supported base. (Bug#8602)
14348 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14350 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14351 to match comment at start of function. This also removes a
14352 GCC warning about overflow in a 32+64-bit port.
14354 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14356 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14357 Reported by Stefan Monnier in
14358 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14359 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14360 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14362 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14363 (EMACS_UINTPTR): Likewise, with uintptr_t.
14365 * lisp.h: Prefer 64-bit EMACS_INT if available.
14366 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14367 on 32-bit hosts that have 64-bit int, so that they can access
14369 However, temporarily disable this change unless the temporary
14370 symbol WIDE_EMACS_INT is defined.
14372 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14374 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14375 This removes an assumption that EMACS_INT and long are the same
14376 width as pointers. The assumption is true for Emacs porting targets
14377 now, but we want to make other targets possible.
14378 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14379 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14380 In the rest of the code, change types of integers that hold casted
14381 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14382 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14383 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14384 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14385 No need to cast type when ORing.
14386 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14387 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14388 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14389 assume EMACS_INT is the same width as char *.
14390 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14391 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14392 Remove no-longer-needed casts.
14393 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14394 (xg_tool_bar_help_callback, xg_make_tool_item):
14395 Use EMACS_INTPTR to hold an integer
14396 that will be cast to void *; this can avoid a GCC warning
14397 if EMACS_INT is not the same width as void *.
14398 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14399 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14400 (current_message_1, set_message_1):
14401 Use a local to convert to proper width without a cast.
14402 * xmenu.c (dialog_selection_callback): Likewise.
14404 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14405 Also, don't assume VALBITS / RAND_BITS is less than 5,
14406 and don't rely on undefined behavior when shifting a 1 left into
14408 * lisp.h (get_random): Change signature to match.
14410 * lread.c (hash_string): Use size_t, not int, for hash computation.
14411 Normally we prefer signed values; but hashing is special, because
14412 it's better to use unsigned division on hash table sizes so that
14413 the remainder is nonnegative. Also, size_t is the natural width
14414 for hashing into memory. The previous code used 'int', which doesn't
14415 retain enough info to hash well into very large tables.
14416 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14418 * dbusbind.c: Don't possibly lose pointer info when converting.
14419 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14420 Use XPNTR rather than XHASH, so that the high-order bits of
14421 the pointer aren't lost when converting through void *.
14423 * eval.c (Fautoload): Don't double-shift a pointer.
14425 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14427 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14429 * gnutls.c (DEF_GNUTLS_FN):
14430 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14432 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14434 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14437 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14439 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14440 New version that can reserve upto 2GB of heap space.
14442 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14444 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14446 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14448 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14449 `gnutls_certificate_set_x509_key_file'.
14451 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
14453 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
14454 Update dependencies.
14456 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14458 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14459 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14460 Remove unused parameter `fildes'.
14461 * process.c (read_process_output, send_process): Don't pass it.
14463 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14465 Fix previous change: the library cache is defined in w32.c.
14466 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14467 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14469 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14471 Implement dynamic loading of GnuTLS on Windows.
14473 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14474 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14475 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14478 * gnutls.c (Qgnutls_dll): Define.
14479 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
14480 (gnutls_*): Declare function pointers.
14481 (init_gnutls_functions): New function to initialize function pointers.

14484 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14485 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
14486 (emacs_gnutls_write, emacs_gnutls_read)
14487 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14488 (Fgnutls_available_p): New function.
14489 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

14499 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
14501 * w32.c (QCloaded_from, Vlibrary_cache): Define.
14502 (w32_delayed_load): Move from image.c. When loading a library, record
14503 its filename in the :loaded-from property of the library id.
14504 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
14505 Initialize and staticpro them.
14506 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
14508 * process.c: Include lisp.h before w32.h, not after.
14509 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
14510 instead of gnutls_record_check_pending.
14512 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
14514 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
14516 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
14517 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
14520 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
14522 * xterm.c (x_set_frame_alpha): Do not set property on anything
14523 else than FRAME_X_OUTER_WINDOW (Bug#8608).
14525 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14527 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
14529 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14531 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

14545 * sysdep.c (wait_for_termination_1): Make static.
14546 (wait_for_termination, interruptible_wait_for_termination):
14547 Move after wait_for_termination_1.
14549 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
14551 * sysdep.c (interruptible_wait_for_termination): New function
14552 which is like wait_for_termination, but allows keyboard
14555 * callproc.c (Fcall_process): Add (:file "file") as an option for
14557 (Fcall_process_region): Ditto.
14559 2011-04-30 Eli Zaretskii <eliz@gnu.org>
14561 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
14562 rather than `XVECTOR (FOO)->size'.
14564 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
14565 inttypes.h, as a gnulib replacement is used if it not available in
14568 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14570 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
14571 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
14572 of MOST_POSITIVE_FIXNUM. (Bug#8528)
14574 * coding.c (coding_alloc_by_realloc): Error out if destination
14575 will grow beyond MOST_POSITIVE_FIXNUM.
14576 (decode_coding_emacs_mule): Abort if there isn't enough place in
14577 charbuf for the composition carryover bytes. Reserve an extra
14578 space for up to 2 characters produced in a loop.
14579 (decode_coding_iso_2022): Abort if there isn't enough place in
14580 charbuf for the composition carryover bytes.
14582 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14584 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
14585 aborting when %lld or %lll format is passed.
14586 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
14587 %llo or %llx format is passed. (Bug#8545)
14589 * window.c (window_scroll_line_based): Use a marker instead of
14590 simple variables to record original value of point. (Bug#7952)
14592 * doprnt.c (doprnt): Fix the case where a multibyte sequence
14593 produced by %s or %c overflows available buffer space. (Bug#8545)
14595 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
14597 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

14607 (command_loop_1): Run `delayed-warnings-hook'
14608 if Vdelayed_warnings_list is non-nil.
14609 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
14610 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
14612 2011-04-28 Eli Zaretskii <eliz@gnu.org>
14614 * doprnt.c (doprnt): Don't return value smaller than the buffer
14615 size if the message was truncated. (Bug#8545).
14617 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14619 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

14622 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14624 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
14626 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
14628 * makefile.w32-in: Update dependencies.
14630 2011-04-27 Eli Zaretskii <eliz@gnu.org>
14632 Improve `doprnt' and its usage. (Bug#8545)
14633 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
14634 `format_end'. Remove support for %l as a conversion specifier.
14635 Don't use xrealloc. Improve diagnostics when the %l size modifier
14636 is used. Update the commentary.
14638 * eval.c (verror): Simplify calculation of size_t.
14640 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
14643 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
14645 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
14648 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14650 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
14651 This makes this file independent of the recent pseudovector change.
14653 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
14655 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
14657 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
14658 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
14659 Remove unused local.
14660 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
14662 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
14663 GCC 4.6.0 optimizes based on type-based alias analysis.
14664 For example, if b is of type struct buffer * and v of type struct
14665 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
14666 != &v->size, and therefore "v->size = 1; b->size = 2; return
14667 v->size;" must therefore return 1. This assumption is incorrect
14668 for Emacs, since it type-puns struct Lisp_Vector * with many other
14669 types. To fix this problem, this patch adds a new type struct
14670 vectorlike_header that documents the constraints on layout of vectors
14671 and pseudovectors, and helps optimizing compilers not get fooled
14672 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
14673 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
14674 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
14676 (XSETPVECTYPE): Rewrite in terms of new macro.
14677 (XSETPVECTYPESIZE): New macro, specifying both type and size.
14678 This is a bit clearer, and further avoids the possibility of
14679 undesirable aliasing.
14680 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
14681 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
14682 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
14683 since Lisp_Subr is a special case (no "next" field).
14684 (ASIZE): Now uses header.size rather than size.
14685 All previous uses of XVECTOR (foo)->size replaced to use this macro,
14686 to avoid the hassle of writing XVECTOR (foo)->header.size.
14687 (struct vectorlike_header): New type.
14688 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
14689 object, to help avoid aliasing.
14690 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
14691 (SUBRP): Likewise, since Lisp_Subr is a special case.
14692 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
14693 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
14694 (struct Lisp_Hash_Table): Combine first two members into a single
14695 struct vectorlike_header member. All uses of "size" and "next" members
14696 changed to be "header.size" and "header.next".
14697 * buffer.h (struct buffer): Likewise.
14698 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
14699 * frame.h (struct frame): Likewise.
14700 * process.h (struct Lisp_Process): Likewise.
14701 * termhooks.h (struct terminal): Likewise.
14702 * window.c (struct save_window_data, struct saved_window): Likewise.
14703 * window.h (struct window): Likewise.
14704 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
14705 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
14706 * buffer.c (init_buffer_once): Likewise.
14707 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
14709 * process.c (Fformat_network_address): Use local var for size,
14712 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
14714 Make the Lisp reader and string-to-float more consistent (Bug#8525)
14715 * data.c (atof): Remove decl; no longer used or needed.
14716 (digit_to_number): Move to lread.c.
14717 (Fstring_to_number): Use new string_to_number function, to be
14718 consistent with how the Lisp reader treats infinities and NaNs.
14719 Do not assume that floating-point numbers represent EMACS_INT
14720 without losing information; this is not true on most 64-bit hosts.
14721 Avoid double-rounding errors, by insisting on integers when
14722 parsing non-base-10 numbers, as the documentation specifies.
14723 * lisp.h (string_to_number): New decl, replacing ...
14724 (isfloat_string): Remove.
14725 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
14726 (read1): Do not accept +. and -. as integers; this
14727 appears to have been a coding error. Similarly, do not accept
14728 strings like +-1e0 as floating point numbers. Do not report
14729 overflow for integer overflows unless the base is not 10 which
14730 means we have no simple and reliable way to continue.
14731 Break out the floating-point parsing into a new
14732 function string_to_number, so that Fstring_to_number parses
14733 floating point numbers consistently with the Lisp reader.
14734 (digit_to_number): Move here from data.c. Make it static inline.
14735 (E_CHAR, EXP_INT): Remove, replacing with ...
14736 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
14737 (string_to_number): New function, replacing isfloat_string.
14738 This function checks for valid syntax and produces the resulting
14739 Lisp float number too. Rework it so that string-to-number
14740 no longer mishandles examples like "1.0e+". Use strtoumax,
14741 so that overflow for non-base-10 numbers is reported only when
14742 there's no portable and simple way to convert to floating point.
14744 * textprop.c (set_text_properties_1): Rewrite for clarity,
14745 and to avoid GCC warning about integer overflow.
14747 * intervals.h (struct interval): Use EMACS_INT for members
14748 where EMACS_UINT might cause problems. See
14749 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
14750 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
14751 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
14753 (offset_intervals): Tell GCC not to worry about length overflow
14754 when negating a negative length.
14756 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
14757 (overrun_check_free): Likewise.
14759 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
14760 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
14763 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14764 (gnutls_make_error): Rename local to avoid shadowing.

14767 Comment out unused local. Fix pointer signedness problems.
14769 * lread.c (openp): Don't stuff size_t into an 'int'.
14770 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
14771 about possible signed overflow.
14773 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14774 (GDK_KEY_g): Don't define if already defined.
14775 (xg_prepare_tooltip): Avoid pointer signedness problem.
14776 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
14778 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
14779 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
14781 * xfns.c (Fx_window_property): Simplify a bit,
14782 to make a bit faster and to avoid GCC 4.6.0 warning.
14783 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
14785 * fns.c (internal_equal): Don't assume size_t fits in int.
14787 * alloc.c (compact_small_strings): Tighten assertion a little.
14789 Replace pEd with more-general pI, and fix some printf arg casts.
14790 * lisp.h (pI): New macro, generalizing old pEd macro to other
14791 conversion specifiers. For example, use "...%"pI"d..." rather
14792 than "...%"pEd"...".
14793 (pEd): Remove. All uses replaced with similar uses of pI.
14794 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
14795 * alloc.c (check_pure_size): Don't overflow by converting size to int.
14796 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
14797 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.

14799 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
14800 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
14802 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
14803 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
14804 * print.c (safe_debug_print, print_object): Likewise.
14805 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
14807 Use pI instead of if-then-else-abort. Use %p to avoid casts,
14808 avoiding the 0 flag, which is not portable.
14809 * process.c (Fmake_network_process): Use pI to avoid cast.
14810 * region-cache.c (pp_cache): Likewise.
14811 * xdisp.c (decode_mode_spec): Likewise.
14812 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
14813 behavior on 64-bit hosts with printf arg.
14814 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
14815 (x_stop_queuing_selection_requests): Likewise.
14816 (x_get_window_property): Don't truncate byte count to an 'int'
14819 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
14820 here, since it parses constructs like leading '-' and spaces,
14821 which are not wanted; and it overflows with large numbers.
14822 Instead, simply match F[0-9]+, which is what is wanted anyway.
14824 * alloc.c: Remove unportable assumptions about struct layout.
14825 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
14826 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
14827 (allocate_vectorlike, make_pure_vector): Use the new macros,
14828 plus offsetof, to remove unportable assumptions about struct layout.
14829 These assumptions hold on all porting targets that I know of, but
14830 they are not guaranteed, they're easy to remove, and removing them
14831 makes further changes easier.
14833 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
14834 This doesn't fix a bug but makes the code clearer.
14835 (string_overrun_cookie): Now const. Use initializers that
14836 don't formally overflow signed char, to avoid warnings.
14837 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
14838 can cause Emacs to crash when string overrun checking is enabled.
14839 (allocate_buffer): Don't assume sizeof (struct buffer) is a
14840 multiple of sizeof (EMACS_INT); it need not be, if
14841 alignof(EMACS_INT) < sizeof (EMACS_INT).
14842 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
14844 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

14871 2011-04-25 Eli Zaretskii <eliz@gnu.org>
14873 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
14874 "cast to pointer from integer of different size".
14876 Improve doprnt and its use in verror. (Bug#8545)
14877 * doprnt.c (doprnt): Document the set of format control sequences
14878 supported by the function. Use SAFE_ALLOCA instead of always
14881 * eval.c (verror): Don't limit the buffer size at size_max-1, that
14882 is one byte too soon. Don't use xrealloc; instead xfree and
14885 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
14887 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

14893 parameters of `gnutls-boot' and documented those parameters in the
14894 docstring. Start callback support.
14895 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
14896 unless a fatal error occurred. Call gnutls_alert_send_appropriate

14974 conversions. Support %l conversion. Don't assume an EMACS_INT
14975 argument for integer conversions and for %c.

14994 * callint.c (Fcall_interactively): When displaying error message
14995 about invalid control letter, pass the character's codepoint, not

15000 codepoint of an invalid character, to avoid displaying a bogus
15003 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15004 `error', not SYMBOL_NAME itself.

15009 * charset.c (check_iso_charset_parameter): Fix incorrect argument
15010 to `error' in error message about FINAL_CHAR argument. Make sure
15011 FINAL_CHAR is a character, and use %c when it is passed as
15012 argument to `error'.
15014 2011-04-23 Eli Zaretskii <eliz@gnu.org>
15016 * s/ms-w32.h (localtime): Redirect to sys_localtime.
15018 * w32.c: Include <time.h>.

15078 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
15079 by pacifying GCC about it. Maybe it's time to retire it?
15080 * xfaces.c (USG, __TIMEVAL__): Likewise.
15082 * dispextern.h (struct redisplay_interface): Rename param
15083 to avoid shadowing.
15084 * termhooks.h (struct terminal): Likewise.
15085 * xterm.c (xembed_send_message): Likewise.
15087 * insdel.c (make_gap_smaller): Define only if
15088 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
15090 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
15093 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
15094 so that we aren't warned about unused symbols.

15131 compatible char. Avoid the old compiler warnings about
15132 out-of-range initializers by using, for example, '\xab' rather
15135 * xgselect.c (xgselect_initialize): Check vs interface
15136 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

15186 (group_in_compile_stack, re_search, re_search_2, regex_compile)
15187 (re_compile_pattern, re_exec): Declare arguments and local
15188 variables `size_t' and `ssize_t' and return values `regoff_t', as

15196 specify buffer/string position and length are now ssize_t and
15197 size_t. Return type is regoff_t.
15199 2011-04-16 Ben Key <bkey76@gmail.com>
15201 * nsfont.m: Fixed bugs in ns_get_family and
15202 ns_descriptor_to_entity that were caused by using free to
15203 deallocate memory blocks that were allocated by xmalloc (via
15204 xstrdup). This caused Emacs to crash when compiled with
15205 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
15206 --enable-checking=xmallocoverrun). xfree is now used to
15207 deallocate these memory blocks.

15634 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
15635 Mark functions with DEFUE instead of DEFUN,
15636 if they are used in other modules.
15637 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
15638 decls for now-static functions.
15639 * buffer.h (Fdelete_overlay): Remove decl.
15640 * callproc.c (Fgetenv_internal): Mark as internal.

15648 * fileio.c (Fmake_symbolic_link): New forward static decl.
15649 * image.c (Finit_image_library): New forward static decl.
15650 * insdel.c (Fcombine_after_change_execute): Make forward decl static.

15675 2011-04-13 Eli Zaretskii <eliz@gnu.org>
15677 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
15678 when at ZV. (Bug#8487)
15680 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
15682 * charset.c (Fclear_charset_maps): Use xfree instead of free.
15684 * keyboard.c (parse_tool_bar_item): Likewise.
15685 * sound.c (sound_cleanup, alsa_close): Likewise.
15686 * termcap.c (tgetent): Likewise.
15687 * xfns.c (x_default_font_parameter): Likewise.
15688 * xsettings.c (read_and_apply_settings): Likewise.
15690 * alloc.c (overrun_check_malloc, overrun_check_realloc)
15691 (overrun_check_free): Protoize.
15693 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
15695 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
15696 since callers should never pass a negative size.
15697 Change the signature to match that of plain 'read' and 'write'; see
15698 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
15699 * lisp.h: Update prototypes of emacs_write and emacs_read.
15701 2011-04-11 Eli Zaretskii <eliz@gnu.org>
15703 * xdisp.c (redisplay_window): Don't try to determine the character
15704 position of the scroll margin if the window start point w->startp
15705 is outside the buffer's accessible region. (Bug#8468)
15707 2011-04-10 Eli Zaretskii <eliz@gnu.org>
15709 Fix write-region and its subroutines for buffers > 2GB.
15710 * fileio.c (a_write, e_write): Modify declaration of arguments and
15711 local variables to support buffers larger than 2GB.
15712 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
15714 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
15715 argument, local variables, and return value.
15717 * lisp.h: Update prototypes of emacs_write and emacs_read.
15719 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
15721 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
15723 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
15725 Fix more problems found by GCC 4.6.0's static checks.
15727 * xdisp.c (vmessage): Use a better test for character truncation.
15729 * charset.c (load_charset_map): <, not <=, for optimization,
15730 and to avoid potential problems with integer overflow.
15731 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
15732 * casetab.c (set_identity, shuffle): Likewise.
15733 * editfns.c (Fformat): Likewise.
15734 * syntax.c (skip_chars): Likewise.
15736 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
15737 This also lets GCC 4.6.0 generate slightly better loop code.
15739 * callint.c (Fcall_interactively): <, not <=, for optimization.
15740 (Fcall_interactively): Count the number of arguments produced,
15741 not the number of arguments given. This is simpler and lets GCC
15742 4.6.0 generate slightly better code.
15744 * ftfont.c: Distingish more carefully between FcChar8 and char.
15745 The previous code passed unsigned char * to a functions like
15746 strlen and xstrcasecmp that expect char *, which does not
15747 conform to the C standard.
15748 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
15749 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
15750 char * when the C standard requires it.
15752 * keyboard.c (read_char): Remove unused var.
15754 * eval.c: Port to Windows vsnprintf (Bug#8435).
15755 Include <limits.h>.
15756 (SIZE_MAX): Define if the headers do not.
15757 (verror): Do not give up if vsnprintf returns a negative count.
15758 Instead, grow the buffer. This ports to Windows vsnprintf, which
15759 does not conform to C99. Problem reported by Eli Zaretskii.
15760 Also, simplify the allocation scheme, by avoiding the need for
15761 calling realloc, and removing the ALLOCATED variable.
15763 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
15765 Remove invocations of doprnt, as Emacs now uses vsnprintf.
15766 But keep the doprint source code for now, as we might revamp it
15767 and use it again (Bug#8435).
15768 * lisp.h (doprnt): Remove.
15769 * Makefile.in (base_obj): Remove doprnt.o.
15770 * deps.mk (doprnt.o): Remove.
15772 error: Print 32- and 64-bit integers portably (Bug#8435).
15773 Without this change, on typical 64-bit hosts error ("...%d...", N)
15774 was used to print both 32- and 64-bit integers N, which relied on
15775 undefined behavior.
15776 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
15777 * lisp.h (error, verror): Mark as printf-like functions.
15778 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
15779 Report overflow in size calculations when allocating printf buffer.
15780 Do not truncate output string at its first null byte.
15781 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
15782 Truncate the output at a character boundary, since vsnprintf does not
15784 * charset.c (check_iso_charset_parameter): Convert internal
15785 character to string before calling 'error', since %c now has the
15787 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
15788 overflow when computing char to be passed to 'error'. Do not
15789 pass Lisp_Object to 'error'; pass the integer instead.
15790 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
15791 formatted with plain %d.
15793 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
15795 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
15797 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
15799 * xterm.c (x_catch_errors): Remove duplicate declaration.
15801 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
15803 * xdisp.c, lisp.h (message_nolog): Remove; unused.
15805 2011-04-10 Jim Meyering <meyering@redhat.com>
15807 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
15808 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
15809 return ssize_t not "int", and use size_t as the buffer length.
15810 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
15811 * gnutls.h: Update declarations.
15812 * process.c (read_process_output): Use ssize_t, to match.
15813 (send_process): Likewise.
15815 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15817 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
15819 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15821 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
15822 Use unsigned char, to match FcChar8 type definition.
15824 * xterm.c (handle_one_xevent):
15825 * xmenu.c (create_and_show_popup_menu):
15826 * xselect.c (x_decline_selection_request)
15827 (x_reply_selection_request): Avoid type-punned deref of X events.
15829 2011-04-09 Eli Zaretskii <eliz@gnu.org>
15831 Fix some uses of `int' instead of EMACS_INT.
15832 * search.c (string_match_1, fast_string_match)
15833 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
15834 (scan_buffer, find_next_newline_no_quit)
15835 (find_before_next_newline, search_command, Freplace_match)
15836 (Fmatch_data): Make some `int' variables be EMACS_INT.
15838 * xdisp.c (display_count_lines): 3rd argument and return value now
15839 EMACS_INT. All callers changed.
15840 (pint2hrstr): Last argument is now EMACS_INT.
15842 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
15843 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
15844 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

15847 (decode_coding_ccl, decode_coding_charset)
15848 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
15849 (decode_coding_iso_2022, decode_coding_emacs_mule)
15850 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
15851 <char_offset, last_offset>: Declare EMACS_INT.

15855 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
15856 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
15858 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
15859 (encode_invocation_designation): Last argument P_NCHARS is now
15861 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
15862 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
15864 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
15867 * ccl.c (Fccl_execute_on_string): Declare some variables
15870 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
15872 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
15874 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
15876 * process.c (Fformat_network_address): Doc fix.
15878 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
15880 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
15882 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
15884 * keyboard.c (read_char): Call Lisp function help-form-show,
15885 instead of using internal_with_output_to_temp_buffer.
15886 (Qhelp_form_show): New var.
15887 (syms_of_keyboard): Use DEFSYM macro.
15889 * print.c (internal_with_output_to_temp_buffer): Function deleted.
15891 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
15893 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
15895 * process.c (Flist_processes): Remove to Lisp.
15896 (list_processes_1): Delete.
15898 2011-04-06 Eli Zaretskii <eliz@gnu.org>
15900 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
15902 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
15904 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
15906 Fix more problems found by GCC 4.6.0's static checks.
15908 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
15910 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
15912 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
15914 * xdisp.c (vmessage): Mark as a printf-like function.
15916 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
15918 * sound.c (sound_warning): Don't crash if arg contains a printf format.
15920 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
15921 printf-like functions.
15922 (tiff_load): Add casts to remove these marks before passing them
15923 to system-supplied API.
15925 * eval.c (Fsignal): Remove excess argument to 'fatal'.
15927 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
15928 This avoids several warnings with gcc -Wstrict-overflow.
15929 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
15930 directly, rather than having caller test rule sign. This avoids
15931 some unnecessary tests.
15932 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
15933 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
15934 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
15936 * xfont.c (xfont_text_extents): Remove var that was set but not used.
15937 (xfont_open): Avoid unnecessary tests.
15939 * composite.c (composition_gstring_put_cache): Use unsigned integer.
15941 * composite.h, composite.c (composition_gstring_put_cache):
15942 Use EMACS_INT, not int, for length.

15945 breaking out part of COMPOSITION_DECODE_RULE.
15946 (COMPOSITION_DECODE_RULE): Use it.

15948 by using the new macro.
15950 * textprop.c (set_text_properties_1): Change while to do-while,
15951 since the condition is always true at first.
15953 * intervals.c (graft_intervals_into_buffer): Mark var as used.
15954 (interval_deletion_adjustment): Return unsigned value.
15957 * process.c (list_processes_1, create_pty, read_process_output):

15967 (update_syntax_table): Use unsigned instead of int.
15969 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
15970 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
15971 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
15973 * print.c (print_error_message): Avoid int overflow.
15975 * font.c (font_list_entities): Redo for clarity,
15976 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
15978 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
15979 (font_score): Avoid potential overflow in diff calculation.
15981 * fns.c (substring_both): Remove var that is set but not used.
15982 (sxhash): Redo loop for clarity and to avoid wraparound warning.
15984 * eval.c (funcall_lambda): Rename local to avoid shadowing.
15986 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
15987 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
15988 can always succeed if overflow has undefined behavior.
15990 * search.c (boyer_moore, wordify): Remove vars set but not used.
15991 (wordify): Omit three unnecessary tests.
15993 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
15994 All callers changed. This avoids the need for an unused var.
15996 * casefiddle.c (casify_region): Remove var that is set but not used.
15998 * dired.c (file_name_completion): Remove var that is set but not used.
16000 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
16002 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16003 (Finsert_file_contents): Remove unnecessary code checking fd.
16005 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
16006 Check for integer overflow on size calculations.
16008 * buffer.c (Fprevious_overlay_change): Remove var that is set
16011 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16012 Remove vars that are set but not used.
16013 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16014 (timer_check_2): Mark vars as initialized.
16016 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16018 * image.c (lookup_image): Remove var that is set but not used.
16019 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16021 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16022 that are set but not used.
16024 * xfns.c (make_invisible_cursor): Don't return garbage
16025 if XCreateBitmapFromData fails (Bug#8410).
16027 * xselect.c (x_get_local_selection, x_handle_property_notify):
16028 Remove vars that are set but not used.
16030 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
16031 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
16033 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
16034 Remove var that is set but not used.

16036 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16037 Check for overflow.
16039 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16040 (map_tty_color) [!defined MSDOS]: Likewise.
16042 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16044 * coding.c: Remove vars that are set but not used.
16045 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
16046 All callers changed.
16047 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
16048 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
16049 (decode_coding_charset): Remove vars that are set but not used.
16051 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
16052 that is set but not used.
16054 * print.c (print_object): Remove var that is set but not used.
16056 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16057 The gnulib version avoids calling malloc in the usual case,
16058 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16059 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16060 * filelock.c (current_lock_owner): Likewise.
16061 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16062 * sysdep.c: Include allocator.h, careadlinkat.h.
16063 (emacs_no_realloc_allocator): New static constant.
16064 (emacs_readlink): New function.
16065 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16066 ../lib/careadlinkat.h.
16068 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
16070 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

16080 * xdisp.c (display_count_lines): Remove parameter `start',
16081 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

16087 (get_per_char_metric): Remove parameter `f', unused since
16088 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
16090 2011-04-02 Jim Meyering <meyering@redhat.com>
16092 do not dereference NULL upon failed strdup
16093 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16094 (ns_get_family): Likewise.
16096 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16098 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16100 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16102 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16105 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16107 Add lexical binding.
16109 * window.c (Ftemp_output_buffer_show): New fun.
16110 (Fsave_window_excursion):
16111 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
16113 * lread.c (lisp_file_lexically_bound_p): New function.
16114 (Fload): Bind Qlexical_binding.
16115 (readevalloop): Remove `evalfun' arg.
16116 Bind Qinternal_interpreter_environment.
16117 (Feval_buffer): Bind Qlexical_binding.
16118 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16120 (syms_of_lread): Declare `lexical-binding'.
16122 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16124 * keyboard.c (eval_dyn): New fun.
16125 (menu_item_eval_property): Use it.
16127 * image.c (parse_image_spec): Use Ffunctionp.
16129 * fns.c (concat, mapcar1): Accept byte-code-functions.
16131 * eval.c (Fsetq): Handle lexical vars.
16132 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16133 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16134 (FletX, Flet): Obey lexical binding.
16135 (Fcommandp): Handle closures.
16136 (Feval): New `lexical' arg.
16137 (eval_sub): New function extracted from Feval. Use it almost
16138 everywhere where Feval was used. Look up vars in lexical env.
16140 (Ffunctionp): Move from subr.el.
16141 (Ffuncall): Handle closures.
16142 (apply_lambda): Remove `eval_flags'.
16143 (funcall_lambda): Handle closures and new byte-code-functions.
16144 (Fspecial_variable_p): New function.
16145 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16146 but without exporting it to Lisp.
16148 * doc.c (Fdocumentation, store_function_docstring):
16149 * data.c (Finteractive_form): Handle closures.
16151 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16154 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16156 (exec_byte_code): New function extracted from Fbyte_code to handle new
16157 calling convention for byte-code-functions. Add new byte-codes.
16159 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
16161 * alloc.c (Fmake_symbol): Init new `declared_special' field.
16163 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16165 * xdisp.c (redisplay_internal): Fix prototype.
16167 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16169 * xdisp.c (SCROLL_LIMIT): New macro.
16170 (try_scrolling): Use it when setting scroll_limit.
16171 Limit scrolling to 100 screen lines.
16172 (redisplay_window): Even when falling back on "recentering",
16173 position point in the window according to scroll-conservatively,
16174 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16176 (try_scrolling): When point is above the window, allow searching
16177 as far as scroll_max, or one screenful, to compute vertical
16178 distance from PT to the scroll margin position. This prevents
16179 try_scrolling from unnecessarily failing when
16180 scroll-conservatively is set to a value slightly larger than the
16181 window height. Clean up the case of PT below the margin at bottom
16182 of window: scroll_max can no longer be INT_MAX. When aggressive
16183 scrolling is in use, don't let point enter the opposite scroll
16184 margin as result of the scroll.
16185 (syms_of_xdisp) <scroll-conservatively>: Document the
16186 threshold of 100 lines for never-recentering scrolling.
16188 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16190 * dispextern.h (move_it_by_lines):
16191 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
16192 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
16193 (message_log_check_duplicate): Remove parameters `prev_bol' and
16194 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16195 (redisplay_internal): Remove parameter `preserve_echo_area',
16196 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16198 * indent.c (Fvertical_motion):
16199 * window.c (window_scroll_pixel_based, Frecenter):
16200 Don't pass `need_y_p' to `move_it_by_lines'.
16202 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16204 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16205 steal a few bits to be more compact.
16206 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16207 Remove unneeded casts.
16209 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16211 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16213 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16214 binding" message (bug#7967).
16216 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16218 Fix more problems found by GCC 4.6.0's static checks.
16220 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16221 Remove unused local var.
16223 * editfns.c (Fmessage_box): Remove unused local var.
16225 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16226 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16227 Omit unused local vars.
16228 * window.c (shrink_windows): Omit unused local var.
16229 * menu.c (digest_single_submenu): Omit unused local var.
16230 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16231 Omit unused local var.
16233 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16234 Don't assume string length fits in int.
16235 (keyremap_step, read_key_sequence): Use size_t for sizes.
16236 (read_key_sequence): Don't check last_real_key_start redundantly.
16238 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
16239 instead of alloca (Bug#8344).
16241 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16242 (Fbacktrace_frame): Don't assume nframes fits in int.
16244 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

16249 * term.c (produce_glyphless_glyph): Remove unnecessary test.
16251 * cm.c (calccost): Turn while-do into do-while, for clarity.
16253 * keyboard.c (syms_of_keyboard): Use the same style as later
16254 in this function when indexing through an array. This also
16255 works around GCC bug 48267.
16257 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16259 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16261 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16262 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16264 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16265 This avoids undefined behavior on integer overflow, and is a bit
16266 more convenient anyway since it is compared to a size_t variable.
16268 Variadic C functions now count arguments with size_t, not int.
16269 This avoids an unnecessary limitation on 64-bit machines, which
16270 caused (substring ...) to crash on large vectors (Bug#8344).

16280 * fns.c (concat): Likewise.
16281 * frame.c (x_set_frame_parameters): Likewise.
16282 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16283 0 if not found, not -1. All callers changed.
16285 * alloc.c (garbage_collect): Don't assume stack size fits in int.
16286 (stack_copy_size): Now size_t, not int.
16287 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
16289 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

16308 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
16309 don't set the hook to nil, but remove the offending function instead.
16310 (Qcommand_hook_internal): Remove, unused.
16311 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
16312 Vcommand_hook_internal.
16314 * eval.c (enum run_hooks_condition): Remove.
16315 (funcall_nil, funcall_not): New functions.
16316 (run_hook_with_args): Call each function through a `funcall' argument.

16493 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
16495 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
16496 unconditionally since it does the check itself.
16498 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
16500 Fix more problems found by GCC 4.5.2's static checks.
16502 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16503 the first time through the loop, since we know p0 < p1 then.
16504 This also avoids a gcc -Wstrict-overflow warning.
16506 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16507 leading to a memory leak, possible in functions like
16508 load_charset_map_from_file that can allocate an unbounded number
16509 of objects (Bug#8318).
16511 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16512 that could (at least in theory) be that large.
16514 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16515 This is less likely to overflow, and avoids undefined behavior if
16516 overflow does occur. All callers changed. Use strtoul to scan
16517 for the unsigned long integer.
16518 (pint2hrstr): Simplify and tune code slightly.
16519 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
16521 * scroll.c (do_scrolling): Work around GCC bug 48228.
16522 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

16529 * fileio.c (Fcopy_file): Report error if fchown or fchmod
16532 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
16534 * process.c (Fmake_network_process): Use socklen_t, not int,
16535 where POSIX says socklen_t is required in portable programs.
16536 This fixes a porting bug on hosts like 64-bit HP-UX, where
16537 socklen_t is wider than int (Bug#8277).
16538 (Fmake_network_process, server_accept_connection):
16539 (wait_reading_process_output, read_process_output):
16542 * process.c: Rename or move locals to avoid shadowing.

16554 Include tparam.h instead, since it declares them.
16555 * cm.h (PC): Remove extern decl; tparam.h now does this.
16556 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
16557 * terminfo.c: Include tparam.h, to check interfaces.
16558 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
16559 (tparam): Adjust signature to match interface in tparam.h;
16560 this removes some undefined behavior. Check that outstring and len
16561 are zero, which they always are with Emacs.
16562 * tparam.h (PC, BC, UP): New extern decls.
16564 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
16565 (xftfont_open): Rename locals to avoid shadowing.
16567 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

16583 (composition_update_it): Mark var as initialized.
16584 (find_automatic_composition): Mark vars as initialized,
16585 with a FIXME (Bug#8290).

16589 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
16590 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
16591 (BUF_DEC_POS): Be more systematic about renaming local temporaries
16592 to avoid shadowing.
16594 * textprop.c (property_change_between_p): Remove; unused.
16596 * intervals.c (interval_start_pos): Now static.
16598 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

16604 Fix pointer signedness.
16605 (alsa_choose_format): Remove unused local var.
16606 (wav_play): Initialize a variable to 0, to prevent undefined
16607 behavior (Bug#8278).
16609 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
16611 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
16613 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
16614 clobbering (Bug#8298).
16615 * sysdep.c (sys_subshell): Likewise.
16616 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
16618 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
16619 This should get cleaned up, so that child_setup has the
16620 same signature on all platforms.
16622 * callproc.c (call_process_cleanup): Now static.
16623 (relocate_fd): Rename locals to avoid shadowing.
16625 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
16627 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
16628 not to be necessary, and produces flickering.
16630 2011-03-20 Glenn Morris <rgm@gnu.org>
16632 * config.in: Remove file.
16634 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
16636 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
16637 are now in src/globals.h.
16638 (syms_of_minibuf): Remove spurious & from previous change.

16648 * xfaces.c (Fx_load_color_file):
16649 Read color file from absolute filename (bug#8250).
16651 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16653 * makefile.w32-in: Update dependencies.
16655 2011-03-17 Eli Zaretskii <eliz@gnu.org>

16664 (sigchld_handler): Now static.
16666 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
16667 That way, the code declares only the vars that it needs.

16677 (CONSTANTLIM): Remove; unused.
16678 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
16679 Define only if needed.
16681 * unexelf.c (unexec): Name an expression,
16682 to avoid gcc -Wbad-function-cast warning.
16683 Use a different way to cause a compilation error if anyone uses
16684 n rather than nn, a way that does not involve shadowing.
16685 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
16687 * deps.mk (unexalpha.o): Remove; unused.
16689 New file unexec.h, the (simple) interface for unexec (Bug#8267).

16691 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
16692 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
16693 Depend on unexec.h.
16694 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
16695 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
16696 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
16697 Change as necessary to match prototype in unexec.h.

16753 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
16754 some of which prompt warnings from gcc -Wbad-function-cast.
16755 (Fformat_time_string, Fencode_time, Finsert_char):
16756 (Ftranslate_region_internal, Fformat):
16757 Rename or remove local vars to avoid shadowing.

16760 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
16763 * lisp.h (eassert): Check that the argument compiles, even if
16764 ENABLE_CHECKING is not defined.
16766 * data.c (Findirect_variable): Name an expression, to avoid
16767 gcc -Wbad-function-cast warning.

16779 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
16780 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
16782 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
16783 (GC_STRING_CHARS): Remove; not used.
16784 (Fmemory_limit): Cast sbrk's returned value to char *.
16786 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
16787 avoids undefined behavior in theory.
16789 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
16791 Use functions, not macros, for up- and down-casing (Bug#8254).
16792 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16793 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
16794 to use the following functions instead of these macros.
16795 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
16796 EMACS_INT, since callers assume the returned value fits in int.
16797 (upcase1): Likewise, for UPCASE_TABLE.
16798 (uppercasep, lowercasep, upcase): New static inline functions.
16799 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

16808 which gcc can warn about.
16809 (regex_compile, re_match_2_internal): Mark locals as initialized.
16810 (RETALLOC_IF): Define only if needed.
16811 (WORDCHAR_P): Likewise. This one is never needed, but is used
16812 only in a comment talking about a compiler bug, so put inside
16813 the #if 0 of that comment.
16814 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
16815 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
16818 * search.c (boyer_moore): Rename locals to avoid shadowing.

16841 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
16842 New macros, so that the caller can use some names other than
16843 gcpro1, gcpro2, etc.
16844 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
16846 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
16847 argument, for consistency with GCPRO2_VAR, etc: it is now the
16848 prefix of the variable, not the variable itself. All uses
16850 * dired.c (directory_files_internal, file_name_completion):
16851 Rename locals to avoid shadowing.
16853 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
16854 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
16855 dired.c's scmp function, had undefined behavior.
16856 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16857 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
16858 * buffer.h: ... to here, because these macros use current_buffer,
16859 and the new implementation with inline functions needs to have
16860 current_buffer in scope now, rather than later when the macros
16862 (downcase, upcase1): New static inline functions.
16863 (DOWNCASE, UPCASE1): Reimplement using these functions.
16864 This avoids undefined behavior in expressions like
16865 DOWNCASE (x) == DOWNCASE (y), which previously suffered
16866 from race conditions in accessing the global variables
16867 case_temp1 and case_temp2.
16868 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
16869 * lisp.h (case_temp1, case_temp2): Remove their decls.
16870 * character.h (ASCII_CHAR_P): Move from here ...
16871 * lisp.h: ... to here, so that the inline functions mentioned
16872 above can use them.
16874 * dired.c (directory_files_internal_unwind): Now static.
16876 * fileio.c (file_name_as_directory, directory_file_name):

16879 (file_name_as_directory): Use const pointers when appropriate.
16880 (Fexpand_file_name): Likewise. In particular, newdir might
16881 point at constant storage, so make it a const pointer.
16882 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
16883 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
16885 (Fset_file_times, Finsert_file_contents, auto_save_error):

16890 to avoid shadowing.
16892 * marker.c (bytepos_to_charpos): Remove; unused.
16894 * lisp.h (verify_bytepos, count_markers): New decls,
16895 so that gcc does not warn that these functions aren't declared.
16897 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
16898 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
16899 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
16900 (copy_text): Remove unused local var.
16902 * filelock.c (within_one_second): Now static.
16903 (lock_file_1): Rename local to avoid shadowing.
16905 * buffer.c (fix_overlays_before): Mark locals as initialized.
16906 (fix_start_end_in_overlays): Likewise. This function should be
16907 simplified by using pointers-to-pointers, but that's a different
16909 (switch_to_buffer_1): Now static.
16910 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
16911 (report_overlay_modification): Rename locals to avoid shadowing.
16913 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
16914 Fix pointer signedness issue.
16915 (sys_subshell): Mark local as volatile if checking for lint,
16916 to suppress a gcc -Wclobbered warning that does not seem to be right.
16917 (MAXPATHLEN): Define only if needed.
16919 * process.c (serial_open, serial_configure): Move decls from here ...
16920 * systty.h: ... to here, so that they can be checked.
16922 * fns.c (get_random, seed_random): Move extern decls from here ...
16923 * lisp.h: ... to here, so that they can be checked.
16925 * sysdep.c (reset_io): Now static.
16926 (wait_for_termination_signal): Remove; unused.
16928 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

16931 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
16932 (DENSE_TABLE_SIZE): Remove; unused.
16933 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
16934 (describe_map_tree):
16935 Rename locals to avoid shadowing.
16937 * keyboard.c: Declare functions static if they are not used elsewhere.

16943 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
16944 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
16945 (read_key_sequence, read_char): Mark locals as initialized.

16955 (DEFINE_DUMMY_FUNCTION): New macro.
16956 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
16958 (main): Add casts to avoid warnings
16959 if GCC considers string literals to be constants.
