3 Omit unused arg EXPECTED from socket hooks.
4 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5 * nsterm.m (ns_term_init):
6 * termhooks.h (struct terminal.read_socket_hook):
7 * w32inevt.c (w32_console_read_socket):
8 * w32term.c (w32_read_socket):
9 * xterm.c (XTread_socket):
10 Omit unused arg EXPECTED. All callers changed.
11 (store_user_signal_events): Return void, not int, since callers no
12 longer care about the return value. All uses changed.
14 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
16 * w32gui.h (XParseGeometry): Do not declare.
18 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
20 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
21 Ignore 'expected'. See Eli Zaretskii in
22 <http://bugs.gnu.org/12471#8> (last line).
24 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
25 (XParseGeometry): Now static. Substitute extremal values for
26 values that are out of range.
28 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
30 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
32 * nsfns.m (XParseGeometry): Remove.
33 (Fx_create_frame): Call x_set_offset to correctly interpret
36 * frame.c (read_integer, XParseGeometry): Moved from w32xfns.c.
37 (Fx_parse_geometry): If there is a space in string, call
38 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
40 2012-09-17 Eli Zaretskii <eliz@gnu.org>
42 * search.c (scan_buffer): Use character positions in calls to
43 region_cache_forward and region_cache_backward, not byte
44 positions. (Bug#12196)
46 * w32term.c (w32_read_socket): Set pending_signals to 1, like
47 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
49 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
50 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
51 emacs_blocked_malloc, now deleted.
53 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
55 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
56 The workaround was for improving performance on Solaris 2.4, but
57 is getting in the way now. Emacs will still work if someone is
58 still running Solaris 2.4 in a museum somewhere; Sun dropped
59 support for Solaris 2.4 in 2003.
60 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
61 * process.c (create_process) [HAVE_WORKING_VFORK]:
62 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
63 since Emacs no longer uses vfork on that platform.
65 2012-09-17 Glenn Morris <rgm@gnu.org>
67 * emacs.c: Use COPYRIGHT.
69 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
71 Remove configure's --without-sync-input option (Bug#12450).
72 When auditing signal-handling in preparation for cleaning it up,
73 I found that SYNC_INPUT has race conditions and would be a real
74 pain to fix. Since it's an undocumented and deprecated
75 configure-time option, now seems like a good time to remove it.
76 Also see <http://bugs.gnu.org/11080#16>.
77 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
78 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
79 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
81 (check_depth) [XMALLOC_OVERRUN_CHECK]:
82 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
83 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
84 (dont_register_blocks, bytes_used_when_reconsidered)
85 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
86 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
87 [!SYSTEM_MALLOC && !SYNC_INPUT]:
88 Remove. All uses removed.
89 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
90 implementation, one that depends on whether the new macro
91 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
93 * atimer.c (run_timers, handle_alarm_signal):
94 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
95 (handle_async_input, process_pending_signals)
96 (handle_input_available_signal, init_keyboard):
97 * nsterm.m (ns_read_socket):
98 * process.c (wait_reading_process_output):
99 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
100 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
102 * xterm.c (XTread_socket):
104 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
105 * eval.c (handling_signal): Remove. All uses removed.
106 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
107 All uses replaced with the SYNC_INPUT version.
108 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
110 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
113 * font.c (Ffont_shape_gstring): Remove unused local.
115 2012-09-16 Glenn Morris <rgm@gnu.org>
117 * Makefile.in (clean): No longer run nextstep's clean.
119 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
121 (ns-app): Move here from ns.mk, and simplify.
122 (clean): Simplify nextstep entry.
123 * ns.mk: Remove file.
125 2012-09-16 Kenichi Handa <handa@gnu.org>
127 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
128 not covert the last few charactes.
130 2012-09-16 Kenichi Handa <handa@gnu.org>
132 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
133 here, but just check the validity of glyphs in the glyph-string.
135 2012-09-16 Martin Rudalics <rudalics@gmx.at>
137 * window.c (Fwindow_parameter, Fset_window_parameter): Accept
138 any window as argument (Bug#12452).
140 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
142 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
143 to ns_term_init to avoid memory leak.
145 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
146 explicit retain/release.
147 (ns_term_init): Only allow one display. Initialize outerpool and
150 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
152 Port _setjmp fix to POSIXish hosts as well as Microsoft.
153 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
154 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
155 the Microsoft problem in a different way, by altering ../nt/config.nt.
157 2012-09-15 Eli Zaretskii <eliz@gnu.org>
172 * w16select.c: Remove inclusion of setjmp.h, as it is now included
173 by lisp.h. This completes removal of setjmp.h inclusion
174 erroneously announced in the previous commit. (Bug#12446)
176 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
179 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
180 not defined as a macro. The latter happens on MS-Windows.
183 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
185 Port better to POSIX hosts lacking _setjmp (Bug#12446).
186 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
187 Some instances of '#include <setjmp.h>' removed, if the
188 only reason for the instance was because "lisp.h" was included.
189 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
190 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
191 and _longjmp with the new symbols. Emacs already uses _setjmp if
192 available, so this change affects only POSIXish hosts that have
193 sigsetjmp but not _setjmp, such as some versions of Solaris and
194 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
195 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
196 (png_load_body) [HAVE_PNG]:
197 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
198 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
199 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
200 since PNG requires jmp_buf. This is the only exception to the
201 general rule that we now use sys_setjmp and sys_longjmp.
202 This exception is OK since this code does not change the signal
203 mask or longjmp out of a signal handler.
205 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
207 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
208 Include "syssignal.h", for 'main_thread'.
210 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
212 Avoid out-of-range marker position (Bug#12426).
213 * insdel.c (replace_range, replace_range_2): Adjust
214 markers before overlays, as suggested by comments.
215 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
216 Remove redundant check before calling offset_intervals.
218 2012-09-14 Martin Rudalics <rudalics@gmx.at>
220 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
221 current buffer (Bug#12387).
223 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
225 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
227 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
229 Use a more backwards-compatible timer format (Bug#12430).
230 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
231 vector element, not from the 4th, since PSECS is now at the end.
232 (Fcurrent_idle_time): Doc fix.
234 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
236 Function to mark objects and remove killed buffers at once.
237 * alloc.c (discard_killed_buffers): Rename to ...
238 (mark_discard_killed buffers) ... new name. Add marking
239 of remaining objects. Fix comment. Adjust users.
240 (mark_object): Do not touch frame buffer lists here.
241 * frame.c (delete_frame): Reset frame buffer lists here.
243 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
245 Better workaround for GNOME bug when --enable-gcc-warnings.
246 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
247 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
248 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
250 Simplify SIGIO usage (Bug#12408).
251 The code that dealt with SIGIO was crufty and confusing, e.g., it
252 played tricks like "#undef SIGIO" but these tricks were not used
253 consistently. Simplify mostly by not #undeffing standard symbols,
254 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
255 or not as we please) rather than "defined SIGIO" (standard symbol
256 that we probably shouldn't #undef).
257 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
258 Modules that need it can include it.
259 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
260 * dispextern.h (ignore_sigio): New decl.
261 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
262 unconditionally, since it's now a no-op if !USABLE_SIGIO.
263 * emacs.c (shut_down_emacs):
264 * keyboard.c (kbd_buffer_store_event_hold):
265 Use ignore_sigio rather than invoking 'signal' directly.
266 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
268 (FIONREAD, SIGIO): Do not #undef.
269 (tty_read_avail_input): Use #error rather than a syntax error.
270 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
271 for I_PIPE, used by SETUP_SLAVE_PTY.
272 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
273 * sysdep.c (croak): Remove; no longer needed. This bit of
274 temporary code, with Fred N. Fish's comment that it's temporary,
275 has been in Emacs since at least 1992!
276 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
277 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
278 * syssignal.h (croak): Remove decl.
279 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
280 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
281 now that we're termios-only.
282 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
283 * term.c (dissociate_if_controlling_tty): Use #error rather than
286 Work around GCC and GNOME bugs when --enable-gcc-warnings.
287 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
288 to work around GNOME bug 683906.
289 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
290 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
291 This works around GCC bug 54561.
293 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
295 More fixes for 'volatile' and setjmp/longjmp.
296 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
297 * image.c (struct png_load_context) [HAVE_PNG]: New type.
298 (png_load_body) [HAVE_PNG]:
299 (jpeg_load_body) [HAVE_JPEG]:
300 New function, with most of the old parent function's body.
301 (png_load) [HAVE_PNG]:
302 (jpeg_load) [HAVE_JPEG]:
303 Invoke the new function, to avoid longjmp munging our locals.
304 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
305 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
306 longjmp is passed 2, as the C standard doesn't guarantee this.
307 Instead, store the failure code into mgr->failure_code.
309 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
311 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
312 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
313 (syms_of_keyboard): Remove support for unread-command-char.
315 2012-09-12 Eli Zaretskii <eliz@gnu.org>
317 * w32proc.c (sys_kill): If PID is our process ID and the signal is
318 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
319 violation. (Bug#12426)
321 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
323 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
325 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
327 * eval.c: Add `inhibit-debugger'.
328 (Qinhibit_debugger): New symbol.
329 (call_debugger): Bind it instead of Qdebug_on_error.
330 (maybe_call_debugger): Test Vinhibit_debugger.
331 (syms_of_eval): Define inhibit-debugger.
332 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
333 (syms_of_xdisp): Remove inhibit-debug-on-message.
335 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
337 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
338 If a nonvolatile local variable is written before a _longjmp to
339 the frame containing the variable, and is read after the _longjmp,
340 the value read is indeterminate. Some local variables of type
341 'struct handler' and 'struct catchtag' are used in this way, so
342 mark each of their slots as volatile if the slot can be set before
343 _longjmp and read afterwards.
344 * lisp.h (struct handler): var and chosen_clause are now volatile.
345 (struct catchtag): val, next, and pdlcount are now volatile.
347 * bidi.c (bidi_push_it, bidi_pop_it):
348 * fns.c (copy_hash_table):
349 * image.c (define_image_type):
350 * keyboard.c (kbd_buffer_store_event_hold):
351 * process.c (Fprocess_send_eof):
352 * xfaces.c (x_create_gc) [HAVE_NS]:
353 * xgselect.c (xg_select):
354 Prefer assignment to memcpy when either will do.
356 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
357 Use pointer-to-a-pointer to simplify and avoid a NILP check each
358 time an item is removed. No need to mark this function 'inline';
359 the compiler knows better than we do.
361 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
363 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
364 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
365 to change_frame_size (Bug#12388).
366 (windowDidResize:): Pass YES to updateFrameSize.
368 * nsterm.h: Add delay parameter to updateFrameSize.
370 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
372 Discard killed buffers from deleted window and frame objects.
373 This reduces an amount of references to killed buffers and
374 helps GC to reclaim them faster.
375 * alloc.c (discard_killed_buffers): New function.
376 (mark_object): Use it for deleted windows and frames.
377 (mark_object): If symbol's value is set up for a killed buffer
378 or deleted frame, restore it's global binding.
379 * data.c (swap_in_global_binding): Add GC notice.
380 (swap_in_symval_forwarding): Use convenient set_blv_where.
381 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
382 * window.h: ... to here.
384 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
386 Convenient macro to check whether the buffer is live.
387 * buffer.h (BUFFER_LIVE_P): New macro.
388 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
389 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
391 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
393 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
394 composition cases (Bug#12364).
396 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
397 overhang of succeeding glyphs overlapping box cursor.
399 * w32term.c (x_draw_glyph_string): Likewise.
401 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
403 Simplify, document, and port floating-point (Bug#12381).
404 The porting part of this patch fixes bugs on non-IEEE platforms
405 with frexp, ldexp, logb.
406 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
408 * floatfns.c: Simplify discussion of functions that Emacs doesn't
409 support, by removing commented-out code and briefly listing the
410 C89 functions excluded. The commented-out stuff was confusing
411 maintenance, e.g., we thought we needed cbrt but it was commented out.
412 (logb): Remove decl; no longer needed.
413 (isfinite): New macro, if not already supplied.
414 (isnan): Don't replace any existing macro.
415 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
416 are present on all C89 platforms.
417 (Ffrexp): Do not special-case zero, as frexp does the right thing
419 (Flogb): Do not use logb, as it doesn't have the desired meaning
420 on hosts that use non-base-2 floating point. Instead, stick with
421 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
422 frexp, to avoid getting an unspecified result.
424 * xdisp.c (Qinhibit_debug_on_message): Now static.
426 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
428 * nsterm.m (ns_update_begin): Set clip path to whole view by using
429 NSBezierPath (Bug#12131).
431 2012-09-10 Chong Yidong <cyd@gnu.org>
433 * fns.c (Fdelq, Fdelete): Doc fix.
435 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
437 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
438 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
440 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
442 * lisp.h (make_lisp_ptr): New macro to replace XSET.
443 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
446 2012-09-09 Eli Zaretskii <eliz@gnu.org>
448 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
449 left fringe if the window has a left margin. This avoids leaving
450 traces of the cursor because its leftmost pixel is not drawn over.
452 * dispnew.c (update_window_line): When the left margin area of a
453 screen line is updated, set the redraw_fringe_bitmaps_p flag of
454 that screen line. (Bug#12277)
456 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
458 Assume C89 or later for math functions (Bug#12381).
459 This simplifies the code, and makes it a bit smaller and faster,
460 and (most important) makes it easier to clean up signal handling
461 since we can stop worring about floating-point exceptions in
462 library code. That was a problem before C89, but the problem
463 went away many years ago on all practical Emacs targets.
464 * data.c, image.c, lread.c, print.c:
465 Don't include <math.h>; no longer needed.
466 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
467 might be autoconfigured, as that never happens.
469 * doprnt.c (DBL_MAX_10_EXP):
471 Remove. C89 or later always defines these.
472 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
473 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
474 (arith_error, domain_error, domain_error2):
475 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
476 no longer needed -- we simply return what C returns. All uses removed.
477 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
479 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
480 Remove. All uses expanded, as these macros are no longer used
481 more than once and are now more trouble than they're worth.
482 (Ftan): Use tan, not sin / cos.
483 (Flogb): Assume C89 frexp.
484 (fmod_float): Assume C89 fmod.
485 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
486 (init_floatfns): Remove. All uses removed.
488 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
490 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
491 compositeToPoint for OSX < 10.6 (Bug#12390).
493 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
495 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
496 This produces more-accurate results.
498 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
500 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
503 2012-09-08 Chong Yidong <cyd@gnu.org>
505 * syntax.c (Fstring_to_syntax): Doc fix.
507 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
509 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
510 in the internal border.
511 (x_set_window_size): Remove static variables and their usage.
512 (ns_redraw_scroll_bars): Fix NSTRACE arg.
513 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
514 fringe/internal border adjustment (Bug#11052).
515 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
516 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
517 (ns_fix_rect_ibw): Remove.
518 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
519 (ns_dumpglyphs_box_or_relief): Ditto.
520 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
522 (ns_dumpglyphs_image): Ditto.
523 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
525 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
526 their usage. Add fringe_extended_p and its use as in other terms.
527 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
528 scroll bar was removed.
529 (updateFrameSize): New function.
530 (windowDidResize): Move code to updateFrameSize and call it.
532 * nsterm.h (EmacsView): Add updateFrameSize.
534 2012-09-07 Chong Yidong <cyd@gnu.org>
536 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
538 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
540 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
542 More signal-handler cleanup (Bug#12327).
543 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
544 Problem introduced when merging patches. Noted by Eli Zaretskii in
545 <http://bugs.gnu.org/12327#67>.
546 * floatfns.c: Comment fix.
547 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
548 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
549 and anyway the declaration is harmless even if SIGDANGER is not defined.
550 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
551 defined BROKEN_FIONREAD). systty.h formerly did this, but other
552 source files not surprisingly expected syssignal.h to define, or
553 not define, SIGIO, and it's cleaner to do it that way, for consistency.
554 Include <sys/ioctl.h>, for FIONREAD.
555 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
556 This eliminates a problem whereby other files mysteriously had
557 to include "syssignal.h" before including "systty.h" if they
558 wanted to use "#ifdef SIGIO".
560 2012-09-07 Eli Zaretskii <eliz@gnu.org>
562 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
564 * w32.c (sigemptyset): Empty the set.
565 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
567 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
569 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
571 * alloc.c (mark_buffer): Revert unsafe marking optimization.
572 (mark_object): Likewise for frame objects.
574 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
576 * syssignal.h (handle_on_main_thread): Always declare,
577 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
578 This ports to platforms without HAVE_PTHREAD.
580 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
582 Signal-handler cleanup (Bug#12327).
583 Emacs's signal handlers were written in the old 4.2BSD style with
584 sigblock and sigmask and so forth, and this led to some
585 inefficiencies and confusion. Rewrite these to use
586 pthread_sigmask etc. without copying signal sets around. Also,
587 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
588 'signal', and instead use functions that do not attempt to take
589 over the system name space. This patch causes Emacs's text
590 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
591 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
592 Do not include <signal.h> or "syssignal.h", as these
593 modules do not use signals.
594 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
595 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
596 Do not include <signal.h>, as "syssignal.h" does that for us now.
597 * atimer.c (sigmask_atimers): New function.
598 (block_atimers, unblock_atimers): New functions,
599 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
601 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
602 no longer needed here.
603 * emacs.c (main): Inspect existing signal handler with sigaction,
604 so that there's no need to block and unblock SIGHUP.
605 * sysdep.c (struct save_signal): New member 'action', replacing
606 old member 'handler'.
607 (save_signal_handlers, restore_signal_handlers):
608 Use sigaction instead of 'signal' to save and restore.
609 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
610 New function. All users of 'signal' modified to use set_sighandler
611 if they're writeonly, and to use sys_signal if they're read+write.
612 (emacs_sigaction_init, forwarded_signal): New functions.
613 (sys_signal): Remove. All uses replaced by calls to sigaction
614 and emacs_sigaction_init, or by direct calls to 'signal'.
615 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
616 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
617 all uses replaced by pthread_sigmask etc. calls.
618 * syssignal.h: Include <signal.h>.
619 (emacs_sigaction_init, forwarded_signal): New decls.
620 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
621 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
622 (sigmask, sys_sigmask): Remove; no longer needed.
623 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
624 (sigblock, sigunblock, sigfree):
625 (sigsetmask) [!defined sigsetmask]:
626 Remove. All uses replaced by pthread_sigmask.
627 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
628 no longer need to be replaced, and its typical old uses
629 are now done via emacs_sigaction_init and sigaction.
630 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
631 (sys_sigdel): Remove; unused.
632 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
634 2012-09-06 Eli Zaretskii <eliz@gnu.org>
636 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
637 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
639 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
641 Explicitly mark buffer_defaults and buffer_local_symbols.
642 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
643 mark_local_symbols here.
644 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
645 since special buffers aren't marked here any more.
646 (allocate_buffer): Chain new buffer with all_buffers here...
647 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
649 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
650 (syms_of_buffer): Remove staticpro of the above.
651 (init_buffer_once): Set names for buffer_defaults and
652 buffer_local_symbols.
654 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
656 Use bool for booleans in font-related modules.
657 * font.c (font_intern_prop, font_style_to_value)
658 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
659 (generate_otf_features, font_check_otf_features, font_check_otf)
660 (font_match_p, font_list_entities, font_at):
661 * fontset.c (fontset_id_valid_p, reorder_font_vector
662 (fontset_find_font, Fset_fontset_font)
663 (face_suitable_for_char_p) [0]:
664 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
665 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
666 (m17n_flt_initialized, ftfont_shape_by_flt):
667 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
668 * nsfont.m (nsfont_draw):
669 * w32font.c (w32font_draw):
670 * w32term.c (x_draw_glyphless_glyph_string_foreground):
671 Use bool for booleans.
672 * font.h: Adjust to above API changes.
673 (struct font, struct font_driver, struct font_driver_list):
674 Use bool for booleans.
675 (struct font): Remove useless member encoding_type.
677 * fontset.c, xftfont.c: Omit unnecessary static decls.
679 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
681 * alloc.c (mark_object): Revert window marking code
682 since it's unsafe for the Fset_window_configuration.
684 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
686 Fix race conditions with signal handlers and errno (Bug#12327).
687 Be more systematic about preserving errno whenever a signal
688 handler returns, even if it's not in the main thread. Do this by
689 renaming signal handlers to distinguish between signal delivery
690 and signal handling. All uses changed.
691 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
692 * data.c (deliver_arith_signal): Rename from arith_error.
693 * dispnew.c (deliver_window_change_signal): Rename from
694 window_change_signal.
695 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
696 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
697 * keyboard.c (deliver_input_available_signal): Rename from
698 input_available_signal.
699 (deliver_user_signal): Rename from handle_user_signal.
700 (deliver_interrupt_signal): Rename from interrupt_signal.
701 * process.c (deliver_pipe_signal): Rename from send_process_trap.
702 (deliver_child_signal): Rename from sigchld_handler.
703 * atimer.c (handle_alarm_signal):
704 * data.c (handle_arith_signal):
705 * dispnew.c (handle_window_change_signal):
706 * emacs.c (handle_fatal_signal, handle_danger_signal):
707 * keyboard.c (handle_input_available_signal):
708 * keyboard.c (handle_user_signal, handle_interrupt_signal):
709 * process.c (handle_pipe_signal, handle_child_signal):
710 New functions, with the actual signal-handling code taken from the
711 original respective signal handlers, sans the sporadic attempts to
712 preserve errno, since that's now done by handle_on_main_thread.
713 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
714 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
715 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
717 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
718 Move initialization of main_thread to sysdep.c's init_signals.
719 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
720 our usage, and simplifies the mainline code.
721 (record_child_status_change): New static function, as a helper
722 for handle_child_signal, and with most of the old child handler's
724 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
725 (handle_child_signal): Use the above.
726 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
727 Moved here from emacs.c.
728 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
729 code moved here from emacs.c's main function.
730 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
731 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
732 lets callers save and restore errno properly.
734 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
736 Remove redundant or unused things here and there.
737 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
738 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
739 * editfns.c (Fcompare_buffer_substrings): Likewise.
740 * frame.h (struct terminal, struct font_driver_list):
741 Remove redundant declarations.
742 * window.h (Qleft, Qright): Likewise.
744 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
746 Do not mark objects from deleted buffers, windows and frames.
747 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
748 (mark_object): Likewise for windows and frames.
750 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
752 * alloc.c (valid_lisp_object_p): Treat killed buffers,
753 buffer_defaults and buffer_local_symbols as valid objects.
754 Return special value to denote them.
756 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
758 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
759 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
760 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
761 (file_name_absolute_p, Fsubstitute_in_file_name):
762 (check_executable, check_writable, Ffile_accessible_directory_p)
763 (Fset_file_selinux_context, Fdefault_file_modes)
764 (Finsert_file_contents, choose_write_coding_system)
765 (Fwrite_region, build_annotations, a_write, e_write)
767 * filelock.c (boot_time_initialized, get_boot_time)
768 (get_boot_time_1, lock_file_1, within_one_second):
769 * floatfns.c (in_float):
770 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
771 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
772 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
773 * lisp.h (struct Lisp_Hash_Table.cmpfn):
774 * window.c (compare_window_configurations):
775 Use bool for booleans.
776 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
777 (Fdefault_file_modes): Now mode_t, not int, for modes.
778 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
779 (internal_delete_file): Now returns void, not a (boolean) int,
780 since nobody was looking at the return value.
781 * lisp.h, window.h: Adjust to above API changes.
783 * xdisp.c (set_message): Simplify and reindent last change.
785 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
787 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
789 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
791 * eval.c (call_debugger): Make the function non-static so that we
792 can call it from set_message.
794 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
795 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
797 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
799 Give more-useful info on a fatal error (Bug#12328).
800 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
801 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
802 of doing the work ourselves.
803 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
805 (fatal_error_backtrace): New function, taken from the guts
806 of the old fatal_error_signal, but with a new option to output
808 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
809 info about the signal than just its number.
810 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
811 * sysdep.c: Include <execinfo.h>
812 (emacs_backtrace): New function, taken partly from the previous
813 code of the 'die' function.
814 (emacs_abort): Call fatal_error_backtrace rather than abort.
816 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
818 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
819 eager (load-time) macro-expansion.
820 * lisp.mk (lisp): Add macroexp.
822 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
824 Simplify redefinition of 'abort' (Bug#12316).
825 Do not try to redefine the 'abort' function. Instead, redo
826 the code so that it calls 'emacs_abort' rather than 'abort'.
827 This removes the need for the NO_ABORT configure-time macro
828 and makes it easier to change the abort code to do a backtrace.
829 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
830 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
831 Remove; sysdep.c's emacs_abort now takes its place.
832 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
833 'abort' changed to use 'emacs_abort'.
834 * msdos.c (dos_abort) [defined abort]: Remove; not used.
835 (abort) [!defined abort]: Rename to ...
836 (emacs_abort): ... new name.
837 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
838 the place of the old 'abort' in emacs.c.
839 * w32.c, w32fns.c (abort): Do not #undef.
840 * w32.c (emacs_abort): Rename from w32_abort.
842 2012-09-04 Eli Zaretskii <eliz@gnu.org>
844 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
845 offsets[j].dv, since the y axis of the screen coordinates points
846 down, while the y axis of the font definition coordinates points
847 up. This fixes display of Arabic diacritics such as KASRA and
848 KASRATAN. (Bug#11860)
850 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
852 Be more systematic about _setjmp vs setjmp.
853 * alloc.c (test_setjmp, mark_stack):
854 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
855 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
856 (png_load, my_error_exit, jpeg_load):
857 * process.c (send_process_trap, send_process):
858 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
859 The underscored versions are up to 30x faster on some hosts.
860 Formerly, the code used setjmp+longjmp sometimes and
861 _setjmp+_longjmp at other times, with no particular reason to
862 prefer setjmp+longjmp.
864 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
866 Fix minor problem found by static checking.
867 * buffer.c (Fdelete_all_overlays): Return nil.
869 2012-09-03 Martin Rudalics <rudalics@gmx.at>
871 * buffer.c (Fdelete_all_overlays): New function.
873 2012-09-03 Chong Yidong <cyd@gnu.org>
875 * gtkutil.c: Add extern decl for Qxft.
877 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
879 * emacs.c, eval.c: Use bool for boolean.
880 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
881 (malloc_using_checking) [DOUG_LEA_MALLOC]:
882 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
883 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
884 (main, decode_env_path, Fdaemon_initialized):
885 * eval.c (call_debugger, Finteractive_p, interactive_p):
886 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
887 (maybe_call_debugger, Fbacktrace):
888 * process.c (read_process_output, exec_sentinel):
889 Use bool for booleans.
890 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
892 * eval.c (interactive_p): Omit always-true boolean argument
893 EXCLUDE_SUBRS_P. All callers changed.
894 * dispextern.h, lisp.h: Reflect above API changes.
895 * firstfile.c (dummy): Use the address of 'main', whose signature
896 won't change, instead of the address of 'initialize', whose
897 signature just changed from int to bool.
898 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
899 * msdos.c (fatal_error_in_progress): ... from here.
900 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
902 (redisplay_internal, unwind_redisplay): Simply clear
903 REDISPLAYING_P when unwinding, instead of saving its previous,
904 always-false value and then restoring it.
906 Clean up some extern decls.
907 Mostly, this hoists extern decls out of .c files and into .h files.
908 That way, we're more likely to catch errors if the interfaces change.
909 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
910 declare xg_mark_data.
911 * dispextern.h (x_frame_parm_handlers):
913 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
914 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
915 (Qultra_bold, Qoblique, Qitalic):
916 Move extern decl here from .c file.
917 * alloc.c (xg_mark_data) [USE_GTK]:
919 * eval.c (Qlexical_binding):
920 * fns.c (time) [!HAVE_UNISTD_H]:
921 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
922 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
923 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
924 * lread.c (Qinternal_interpreter_environment):
925 * minibuf.c (Qbuffer):

994 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
995 more than one grapheme cluster passed to the shaper: compute the
996 offset adjustment values separately for each cluster. (Bug#11860)
998 * image.c: Restore mistakenly removed inclusion of w32.h. Without
999 it, GCC doesn't see prototypes of w32_delayed_load, and complains

1120 for GCC 4.7.1 x86-64.
1122 2012-08-30 Glenn Morris <rgm@gnu.org>
1124 * lread.c (init_lread): For out-of-tree builds, only add the
1125 source directory's site-lisp dir to the load-path if it exists,
1126 consistent with in-tree builds. (Bug#12302)
1128 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

1156 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
1157 is not one of the heaps we manage. (Bug#12242)
1159 2012-08-28 Glenn Morris <rgm@gnu.org>

1358 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
1359 are all boolean, so make them single-bit bitfields.
1361 * lisp.h (ASET): Remove attempt to detect side effects.
1362 It was meant to be temporary and it often doesn't work,
1363 because when IDX has side effects the behavior of IDX==IDX
1364 is undefined. See Stefan Monnier in
1365 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
1367 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

1373 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1375 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
1376 as that's faster and simpler than static storage. Don't bother
1377 with the g_main_context_query overhead if g_main_context_pending
1378 says no events are pending.
1379 (gfds, gfds_size): Remove these static vars.
1380 (xgselect_initialize): Remove; no longer needed.
1381 All uses and decls removed.
1383 * emacs.c (fatal_error_signal_hook): Remove.
1384 All uses removed. This leftover from old code was always 0.
1386 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
1387 * casefiddle.c (casify_object, casify_region):
1388 * casetab.c (set_case_table):
1389 * category.c, category.h (word_boundary_p):
1390 * category.h (CHAR_HAS_CATEGORY):
1391 Use bool for booleans, instead of int.
1393 2012-08-25 Eli Zaretskii <eliz@gnu.org>
1395 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
1397 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1399 On assertion failure, print backtrace if available.
1400 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1401 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1402 * Makefile.in (LIB_EXECINFO): New macro.
1405 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1406 * bytecode.c (exec_byte_code):
1407 * callint.c (check_mark, Fcall_interactively):
1408 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1409 (getenv_internal, sync_process_alive, call_process_exited):
1410 * lisp.h (USE_SAFE_ALLOCA):
1411 Use bool for booleans, instead of int.
1412 * lisp.h, process.h: Adjust prototypes to match above changes.
1413 * callint.c (Fcall_interactively): Don't assume the mark's
1414 offset fits in 'int'.
1416 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1418 * buffer.c, buffer.h: Use bool for boolean.
1419 * buffer.c (reset_buffer_local_variables)
1420 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1421 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
1422 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
1423 (overlay_touches_p, overlay_strings, Foverlay_put)
1424 (report_overlay_modification, call_overlay_mod_hooks):
1425 (mmap_enlarge, mmap_set_vars):
1426 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1427 Use bool for booleans, instead of int.
1428 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1429 since the 1-or-0 return value is always ignored anyway.
1430 (mmap_initialized_p):
1431 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1432 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1434 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1436 * bidi.c: Use bool for boolean.
1437 This is a bit more readable, and makes the text segment of bidi.o
1438 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1439 Presumably it's faster too.
1440 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1442 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1443 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1444 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1445 (bidi_explicit_dir_char, bidi_level_of_next_char)
1446 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1447 Use bool for booleans, instead of int.
1448 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1449 (bidi_unshelve_cache): Adjust decls to match code.
1451 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1453 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1456 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1458 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1459 * atimer.h: Include <stdbool.h>.
1461 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1463 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1464 compile time tests instead of run time tests on systems that do
1466 (FRAME_MAC_P): Remove leftover from deleted code.
1467 * frame.c (syms_of_frame): Remove leftover from deleted code.
1469 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>

1473 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1475 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1476 Otherwise, the compiler complains about (A?B:C) where B is void
1477 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1478 (fontset_add): Return void, for FONTSET_ADD.
1480 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1482 * alloc.c: Use bool for booleans.
1483 (gc_in_progress, abort_on_gc)
1484 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1485 (dont_register_blocks) [GC_MALLOC_CHECK]:
1486 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1487 (check_string_bytes, make_specified_string, memory_full)
1488 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1489 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1490 (mark_stack, valid_pointer_p, make_pure_string)
1491 (Fgarbage_collect, survives_gc_p, gc_sweep):
1492 Use bool for booleans, instead of int.
1493 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1494 Remove unused local.
1495 * alloc.c (PURE_POINTER_P):
1496 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1497 * editfns.c (Fformat):
1498 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1500 * fns.c (sweep_weak_table):
1501 * lisp.h (suppress_checking, push_message, survives_gc_p)
1502 (make_pure_string, gc_in_progress, abort_on_gc):
1503 * lread.c (readchar, read1):
1504 * print.c (Fprin1_to_string):
1505 * xdisp.c (push_message):
1506 Use bool for booleans affected directly or indirectly by
1509 Make recently-introduced setters macros.
1510 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1511 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1512 (set_fontset_default, set_fontset_fallback): Rename from their
1513 upper-case counterparts, and make them functions rather than macros.
1514 This is more consistent with the other recently-introduced setters.
1515 These don't need to be inline, since they're local.
1517 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1519 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1520 the loop (Bug#12247).
1522 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1524 * lisp.h (vcopy): Use memcpy rather than our own loop.
1525 This fixes a performance regression introduced by the recent
1526 addition of vcopy. This means 'vcopy' will need to be modified
1527 for a copying collector, but that's OK. Also, tighten the
1528 checking in the assertion.
1530 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1532 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1533 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1534 non-base glyph for the width of the base character, according to
1535 what x_draw_composite_glyph_string_foreground expects.
1536 Generate WADJUST value according to composition_gstring_width's
1537 expectations, to produce correct width of the composed character.
1538 Reverse the sign of the DU offset produced by ScriptPlace.
1540 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1542 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1544 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1546 Avoid direct writes to contents member of struct Lisp_Vector.
1547 * lisp.h (vcopy): New function to copy data into vector.

1549 * fns.c (Ffillarray): Use ASET.
1550 * keyboard.c (timer_check_2): Use AREF and ASET.
1551 (append_tool_bar_item, Frecent_keys): Use vcopy.
1552 * lread.c (read_vector): Use ASET.
1553 * msdos.c (Frecent_doskeys): Use vcopy.
1554 * xface.c (Finternal_copy_lisp_face): Use vcopy.

1561 the position of its buffer's point.
1562 (Fset_window_point): For the selected window always go in its
1563 buffer to the specified position.
1565 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1567 Setter macros for fontsets.
1568 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1569 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1570 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1573 2012-08-20 Glenn Morris <rgm@gnu.org>
1575 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1576 Don't assume that `ln -f' works.
1578 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1580 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1581 and later about non-assignments with no effect. See discussion at
1582 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1585 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1587 Inline setter functions for Lisp_Objects slots of struct specbinding.
1588 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
1591 2012-08-20 Martin Rudalics <rudalics@gmx.at>
1593 * window.c (select_window): Always make selected window's buffer
1596 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1598 Use AREF and ASET for docstrings of category tables.
1599 * category.h (CATEGORY_DOCSTRING): Use AREF.
1600 (SET_CATEGORY_DOCSTRING): Use ASET.
1601 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
1603 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1605 Inline setter functions for hash table members.
1606 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
1607 (set_hash_hash, set_hash_index): Rename with _slot suffix.
1608 (set_hash_key_and_value, set_hash_index, set_hash_next)
1609 (set_hash_hash): New functions.
1610 * charset.c, fns.c: Adjust users.
1612 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1614 Inline getter and setter functions for per-buffer values.
1615 * buffer.h (per_buffer_default, set_per_buffer_default)
1616 (per_buffer_value, set_per_buffer_value): New functions.
1617 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
1618 * buffer.c, data.c: Adjust users.
1620 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
1622 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
1624 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
1626 Rely on <config.h> + <unistd.h> to declare 'environ',
1627 as gnulib does this if the system doesn't.
1628 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
1629 Remove declaration. MS-Windows declares it on stdlib.h which is
1630 included by conf_post.h.
1631 * emacs.c (environ) [DOUG_LEA_MALLOC]:
1632 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
1633 * vm-limit.c: Include <unistd.h>, for 'environ'.
1635 * unexaix.c, unexcoff.c: Include "mem-limits.h".
1636 (start_of_data): Remove decl; mem-limits.h provides it.
1638 * xdisp.c (handle_invisible_prop): Make it a bit faster
1639 and avoid a gcc -Wmaybe-uninitialized diagnostic.
1641 2012-08-19 Chong Yidong <cyd@gnu.org>
1643 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
1646 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
1648 * .gdbinit: Use call instead of set when calling a function in the
1651 * data.c (set_internal): Don't use set_blv_found.
1652 (Fkill_local_variable): Likewise.
1654 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
1656 * nsfont.m (ns_ascii_average_width): Ensure the string
1657 ascii_printable is initialized with a null-terminated character
1658 array. Otherwise, it can contain undesired extra characters.
1660 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1662 port new setting code to Sun C 5.8 2005/10/13
1663 * chartab.c, lisp.h (char_table_set, char_table_set_range):
1664 Return void, not Lisp_Object. Otherwise, the compiler
1665 complains about (A?B:C) where B is void and C is Lisp_Object
1666 when compiling CHAR_TABLE_SET, due to the recent change to
1667 the API of sub_char_table_set_contents.
1669 2012-08-18 Chong Yidong <cyd@gnu.org>
1671 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
1672 for the string case (Bug#3874).
1674 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1676 * buffer.h (BSET): Remove (Bug#12215).

2500 * w32.c (init_environment): Change the default values of many
2501 environment variables in dflt_envvars[] to NULL, to avoid pushing
2502 them into environment when they were not already defined.
2503 Remove the code that deletes site-lisp subdirectories from the default
2504 value of EMACSLOADPATH, as it is no longer needed.
2505 (check_windows_init_file): Now external, not static.
2506 Use Vload_path as is, without adding anything, as this function is now
2507 called when Vload_path is already set up.

2511 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

2555 Remove unnecessary pointer casts.
2556 * alloc.c (record_xmalloc): New function.
2557 * lisp.h (record_xmalloc): New decl.
2558 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
2559 more like a function. This is because the pointer cast is not
2560 needed. All uses changed.
2561 * print.c (print_string, print_error_message): Avoid length recalc.
2563 Improve fix for macroexp crash with debugging (Bug#12118).
2564 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
2565 ARRAY_MARK_FLAG when checking subscripts, because ASET is

2598 with addition of handling of symlinks and support for 'lstat'.
2599 If possible, get file's attributes and security information by
2600 handle, not by name. Produce S_IFLNK bit for symlinks, when
2601 called from 'lstat'.
2602 (stat, lstat): New functions, call 'stat_worker'.
2603 (symlink, readlink, careadlinkat): Rewritten to create and resolve
2604 symlinks when the underlying filesystem supports them.
2606 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
2608 Fix macroexp crash on Windows with debugging (Bug#12118).
2609 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
2610 checking subscripts; problem introduced with the recent
2611 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
2612 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
2613 since it's used in non-static inline functions now.
2615 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
2616 Don't assume buffer size fits in 'int'. Remove unused local.

2637 * dispnew.c (DISPEXTERN_INLINE):
2638 * sysdep.c (SYSTIME_INLINE):
2639 Define to EXTERN_INLINE, so that the corresponding functions
2640 are compiled into code.
2641 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
2642 (INLINE_HEADER_END): New macros.
2643 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

2663 hard-coding the path separator.
2665 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
2667 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
2668 This how ASET and AREF are supposed to work, and makes
2669 it easier to think about future improvements. See
2670 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
2671 * charset.h (set_charset_attr): New function.

3160 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
3161 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
3162 emacs.c, as this is a more-suitable home. Had this been done earlier
3163 the fix for 12036 would have avoided some of the problems noted in
3164 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
3165 would have been more obvious.
3166 * emacs.c: Do not include <verify.h>; no longer needed.
3167 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
3168 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
3169 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3170 Remove; now done in lisp.h.
3171 * lisp.h (PUBLISH_TO_GDB): New macro.

3175 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3176 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3177 not be usable in #if. This simplifies things.
3179 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
3181 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
3183 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

3186 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3187 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3188 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3189 Adjust to changes in lisp.h and emacs.c, by using
3190 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
3191 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
3192 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
3193 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
3194 instead of gdb_valbits.
3195 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
3196 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
3197 instead of gdb_array_mark_flag.
3198 (xboolvector): Get size from $->size, not $->header.size.
3199 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
3200 (xreload, hook-run, hookpost-run): Remove.
3201 * emacs.c: Include <verify.h>.
3202 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
3203 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
3205 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
3206 (gdb_USE_LSB_TAG): New enum constants.
3207 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3208 Also define these as enum constants, so they're visible to GDB.
3209 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
3210 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
3211 as constants, so they're visible to GDB.

3213 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
3214 Now enum constants, not macros, so they're visible to GDB.
3215 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
3216 more convenient now. All uses changed.
3217 (VALMASK) [USE_LSB_TAG]: Also define in this case.
3218 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
3220 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

3227 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
3228 add argument, tune behavior, and adjust all callers.
3230 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
3232 Use typedef for EMACS_INT, EMACS_UINT.
3233 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
3234 than macros. This simplifies debugging in the usual case, since
3235 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
3236 and it allows expressions involving EMACS_INT casts.
3237 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
3239 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

3251 Adjust buffer text indirection counters at the end of Fkill_buffer.
3252 * buffer.c (Fkill_buffer): Adjust indirection counters when the
3253 buffer is definitely dead. This should really fix an issue reported
3254 by Christoph Scholtes again. (Bug#12007).
3255 (init_buffer_once): Initialize indirection counters of
3256 buffer_defaults and buffer_local_symbols (for sanity and safety).
3258 2012-07-24 Eli Zaretskii <eliz@gnu.org>
3260 * xdisp.c (init_iterator): Don't compute dimensions of truncation
3261 and continuation glyphs on tooltip frames, leave them at zero.

3289 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3291 Swap buffer text indirection counters in Fbuffer_swap_text.
3292 * buffer.c (Fbuffer_swap_text): Swap indirections too.
3293 This avoids crash reported by Christoph Scholtes at
3294 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
3296 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
3298 * nsmenu.m (Popdown_data): New struct.

3321 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
3323 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
3324 as it's limited by the amount of memory, not by INT_MAX.
3326 2012-07-21 Eli Zaretskii <eliz@gnu.org>
3328 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
3329 in special-event-map. See the discussion at

3479 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3481 * eval.c (Fdefvar): Don't check constants since we only set the var if
3482 it's not yet defined anyway (bug#11904).
3484 * lisp.h (last_undo_boundary): Declare new var.
3485 * keyboard.c (command_loop_1): Set it.
3486 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
3487 were auto-added by the command loop (bug#11774).

4046 * sound.c (DEFAULT_SOUND_DEVICE) [!WINDOWSNT]:
4047 * s/netbsd.h (DEFAULT_SOUND_DEVICE): Let configure set it.
4049 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
4051 Remove "#define unix" that is no longer needed (Bug#11905).
4052 * s/aix4-2.h (unix): Remove; no longer needed.
4054 EMACS_TIME simplification (Bug#11875).
4055 This replaces macros (which typically do not work in GDB)
4056 with functions, typedefs and enums, making the code easier to debug.
4057 The functional style also makes code easier to read and maintain.
4058 * systime.h: Include <sys/time.h> on all hosts, not just if
4059 WINDOWSNT, since 'struct timeval' is needed in general.
4060 (EMACS_TIME): Now a typedef, not a macro.
4061 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
4063 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
4064 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
4065 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
4066 (EMACS_TIME_LE): Now functions, not macros.
4067 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
4068 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
4069 which are not functions. All uses rewritten to use:
4070 (make_emacs_time): New function.
4071 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
4072 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4073 not functions. All uses rewritten to use the following, respectively:
4074 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
4075 (add_emacs_time, sub_emacs_time): New functions.
4076 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
4077 * fileio.c (Fcopy_file):
4078 * xterm.c (XTflash): Get the current time closer to when it's used.
4079 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
4081 * bytecode.c (targets): Suppress -Woverride-init warnings.
4083 Simplify by avoiding confusing use of strncpy etc.
4084 * doc.c (Fsnarf_documentation):
4085 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
4086 * frame.c (Fmake_terminal_frame):
4087 * gtkutil.c (get_utf8_string):
4089 * nsmenu.m (ns_update_menubar):
4090 * regex.c (regerror):
4091 Prefer memcpy to strncpy and strncat when either will do.
4092 * fileio.c (Fsubstitute_in_file_name):
4093 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
4094 (menu_separator_name_p):
4095 * nsmenu.m (ns_update_menubar):
4096 Prefer memcmp to strncmp when either will do.
4097 * nsterm.m: Include <ftoastr.h>.
4099 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
4100 Prefer snprintf to strncpy.
4101 * nsterm.m (ns_term_init):
4102 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4103 * nsterm.m (ns_term_init):
4104 Avoid the need for strncpy, by using build_string or
4105 make_unibyte_string directly. Use dtoastr, not snprintf.
4106 * process.c (Fmake_network_process): Diagnose service names that
4107 are too long, rather than silently truncating them or creating
4108 non-null-terminated names.
4109 (Fnetwork_interface_info): Likewise, for interface names.
4110 * sysdep.c (system_process_attributes) [GNU_LINUX]:
4111 Prefer sprintf to strncat.
4112 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
4113 Prefer vsnprintf to vsprintf + strncpy.
4115 2012-07-10 Glenn Morris <rgm@gnu.org>
4117 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
4118 Clarify fallback case.
4120 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4122 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
4123 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
4124 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
4125 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
4126 where argument type is known to be a Lisp_Cons.
4128 2012-07-10 Tom Tromey <tromey@redhat.com>
4130 * bytecode.c (BYTE_CODE_THREADED): New macro.
4131 (BYTE_CODES): New macro. Replaces all old byte-code defines.
4132 (enum byte_code_op): New type.
4133 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
4134 (exec_byte_code): Use them. Use token threading when applicable.
4136 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4138 Optimize pure C strings initialization.
4139 * lisp.h (make_pure_string): Fix prototype.
4140 (build_pure_c_string): New function, defined as static inline. This
4141 provides a better opportunity to optimize away calls to strlen when
4142 the function is called with compile-time constant argument.
4143 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
4144 argument, adjust users accordingly. Use build_pure_c_string where
4146 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
4147 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
4148 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
4150 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4152 Avoid calls to strlen in miscellaneous functions.
4153 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
4154 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
4155 * lread.c (openp): Likewise.
4157 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4159 Avoid calls to strlen in path processing functions.
4160 * fileio.c (file_name_as_directory): Add comment. Change to add
4161 srclen argument and return the length of result. Adjust users
4163 (directory_file_name): Fix comment. Change to add srclen argument,
4164 swap 1st and 2nd arguments to obey the common convention.
4165 Adjust users accordingly.
4166 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
4168 2012-07-10 Glenn Morris <rgm@gnu.org>
4170 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
4171 Move PENDING_OUTPUT_COUNT definition to configure.
4173 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
4174 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
4175 * s/gnu.h (DATA_START): Move definitions to configure.
4177 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
4178 We include usg5-4-common.h, which defines them both.
4180 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
4181 O_RDONLY already includes it).
4183 Stop ns builds setting the EMACSLOADPATH environment variable.
4184 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4185 Now it does not set EMACSLOADPATH, just returns the load-path string.
4186 * nsterm.h: Update accordingly.
4187 * lread.c [HAVE_NS]: Include nsterm.h.
4188 (init_lread) [HAVE_NS]: Use ns_load_path.
4189 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
4191 2012-07-09 Glenn Morris <rgm@gnu.org>
4193 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
4194 since the included bsd-common.h does so.
4196 Stop ns builds setting the EMACSPATH environment variable.
4197 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
4198 (ns_init_paths): Do not set EMACSPATH.
4199 * nsterm.h (ns_exec_path): Add it.
4200 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
4203 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
4205 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
4207 * process.c (wait_reading_process_output): 'waitchannels' was unset
4208 when read_kbd || !NILP (wait_for_cell); fix this.
4210 Add GCC-style 'const' attribute to functions that can use it.
4211 * character.h (char_resolve_modifier_mask):
4212 * keyboard.h (make_ctrl_char):
4213 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
4214 (init_character_once, next_almost_prime, init_fns, init_image)
4215 (flush_pending_output, init_sound):
4216 * mem-limits.h (start_of_data):
4217 * menu.h (finish_menu_items):
4218 Add ATTRIBUTE_CONST.

4220 Declare the dummy function with ATTRIBUTE_CONST.
4221 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
4222 Add decls with ATTRIBUTE_CONST.
4224 Minor improvements to make_formatted_string.
4225 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
4226 where int is good enough, as vsprintf returns an int.
4227 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
4229 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4231 Use make_formatted_string to avoid double length calculation.
4232 * lisp.h (make_formatted_string): New prototype.
4233 * alloc.c (make_formatted_string): New function.
4234 * buffer.c (Fgenerate_new_buffer_name): Use it.
4235 * dbus.c (syms_of_dbusbind): Likewise.
4236 * editfns.c (Fcurrent_time_zone): Likewise.
4237 * filelock.c (get_boot_time): Likewise.
4238 * frame.c (make_terminal_frame, set_term_frame_name)
4239 (x_report_frame_params): Likewise.
4240 * image.c (gs_load): Likewise.
4241 * minibuf.c (get_minibuffer): Likewise.
4242 * msdos.c (dos_set_window_size): Likewise.
4243 * process.c (make_process): Likewise.
4244 * xdisp.c (ensure_echo_area_buffers): Likewise.

4247 2012-07-09 Glenn Morris <rgm@gnu.org>
4249 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
4250 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
4251 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
4252 * nsterm.h (ns_etc_directory): Add it.

4254 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
4256 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4258 Move marker debugging code under MARKER_DEBUG.
4259 * marker.c (MARKER_DEBUG): Move marker debugging code under
4260 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4261 for bootstrap with --enable-checking (~3x slowdown reported
4262 by Juanma Barranquero <lekktu@gmail.com>).
4263 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4265 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4267 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
4268 See <http://bugs.gnu.org/11825#29>.
4270 2012-07-08 Eli Zaretskii <eliz@gnu.org>
4272 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4273 has no font, use the frame's font. (Bug#11813)
4274 (display_line): Add commentary about displaying truncation glyphs
4276 (produce_special_glyphs): Move here from term.c.
4278 * term.c (produce_special_glyphs): Move to xdisp.c.
4280 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4283 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4285 * xdisp.c (display_line): Avoid warning about implicit declaration
4288 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4290 * lisp.h: Remove empty conditional.
4292 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4294 * lread.c (load_path_check): Now static.
4296 Fix some minor --with-ns problems found by static checking.
4297 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
4298 (x_set_font) [!HAVE_X_WINDOWS]:
4299 * image.c (xpm_load_image) [HAVE_NS]:
4300 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4301 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4302 Remove unused local.
4303 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
4304 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
4305 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
4306 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
4307 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
4308 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
4309 Fix pointer signedness problem.
4310 * xfaces.c (FRAME_X_FONT_TABLE):
4311 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
4313 2012-07-07 Glenn Morris <rgm@gnu.org>
4315 * lread.c (load_path_check): New function, split from init_lread.
4316 (init_lread): Reorganize. Motivation:
4317 If EMACSLOADPATH is set, check/warn about that rather than the
4318 defaults, which we are not going to use. Hence we can remove
4319 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4320 Don't warn if site-lisp directories are missing.
4321 If not installed, start from a blank load-path, since
4322 PATH_LOADSEARCH refers to the eventual installation directories.
4324 2012-07-07 Eli Zaretskii <eliz@gnu.org>
4326 Support truncation and continuation glyphs on GUI frames, when
4327 fringes are disabled. (Bug#11832)
4328 * xdisp.c (init_iterator): Get dimensions of truncation and
4329 continuation glyphs even if on GUI frames.
4330 Adjust it->last_visible_x on GUI frames when the left or right fringes,
4331 or both, are absent.
4332 (start_display, move_it_in_display_line_to): Handle the case of a
4333 GUI frame without a fringe to display continuation or truncation
4335 (insert_left_trunc_glyphs): Support GUI frames: make sure
4336 truncation glyphs overwrite enough glyphs from the current line to
4337 have sufficient space in pixels.
4338 (display_line): Support truncation and continuation glyphs on GUI
4339 frames. If some spare pixels are left on the line after inserting
4340 the truncation glyphs, fill that space with a stretch glyph of a
4341 suitably computed width.
4343 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4344 produce_glyphs, to support GUI sessions.
4346 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4348 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4350 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4352 Do not require float-time's arg to fit in time_t (Bug#11825).
4353 This works better on hosts where time_t is unsigned, and where
4354 float-time is applied to the (negative) difference between two times.
4355 * editfns.c (decode_time_components): Last arg is now double *,
4356 not int *, and means to store all the result as a double, without
4357 worrying about whether the seconds part fits in time_t.
4358 All callers changed.
4359 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4360 All callers changed.
4361 (Ffloat_time): Do not fail merely because the specified time falls
4362 outside of time_t range.
4364 2012-07-07 Glenn Morris <rgm@gnu.org>
4366 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
4367 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
4368 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
4370 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
4372 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
4373 Update dependencies.
4375 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
4377 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4379 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
4380 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
4381 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
4382 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
4383 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
4384 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
4386 * xfont.c (compare_font_names): Redo to omit the need for casts.
4388 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4390 * xfns.c (Fx_change_window_property): Doc fix.
4391 * w32fns.c (Fx_change_window_property): Doc fix.
4393 * w32fns.c (Fx_window_property): Accept the same arguments as the
4394 X Windows version. Doc fix.
4395 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4397 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4398 Eli Zaretskii <eliz@gnu.org>
4400 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4401 Windows-specific code from nt/config.nt moved here.
4402 Obsolete settings removed.
4404 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4406 * process.c: Avoid unnecessary calls to gettime.
4407 (wait_reading_process_output): Don't get the time of day
4408 when gobbling data immediately and not waiting, as there's no need
4409 for it in that case. This removes a FIXME.
4411 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4413 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4414 is defined (Bug#11768).
4416 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4418 Fix marker debugging code.
4419 * marker.c (byte_char_debug_check): Do not perform the check
4420 if buffer is not multibyte.
4421 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4422 Call byte_char_debug_check with correct arguments.
4424 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4426 Compile marker debugging code only if ENABLE_CHECKING is defined.
4427 * marker.c (byte_char_debug_check, count_markers):
4428 Use only if ENABLE_CHECKING is defined.
4429 (byte_debug_flag): Remove.
4430 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4431 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4433 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4435 Avoid code repetition in marker-related functions.
4436 * marker.c (attach_marker): New function.
4437 (Fset_marker, set_marker_restricted, set_marker_both)
4438 (set_marker_restricted_both): Use it.
4439 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4440 Consistently rename charno to charpos.
4441 (marker_position): Add eassert.
4442 (marker_byte_position): Convert to eassert.
4444 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4446 Simplify list operations in unchain_overlay and unchain_marker.
4447 * buffer.c (unchain_overlay): Simplify. Add comment.
4448 * marker.c (unchain_marker): Simplify. Fix comments.
4450 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4452 Introduce fast path for the widely used marker operation.
4453 * alloc.c (build_marker): New function.
4454 * lisp.h (build_marker): New prototype.
4455 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
4456 * composite.c (autocmp_chars): Likewise.

4458 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
4459 (save_restriction_save): Use build_marker.
4460 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
4461 * window.c (save_window_save): Likewise.
4463 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4465 Do not use Fdelete_overlay in delete_all_overlays
4466 to avoid redundant calls to unchain_overlay.
4467 * buffer.c (drop_overlay): New function.
4468 (delete_all_overlays, Fdelete_overlay): Use it.
4469 * minibuf.c (get_minibuffer): Fix comment.
4471 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4473 Port to OpenBSD 5.1 amd64.
4474 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4475 This is needed for OpenBSD, and should be harmless on all BSD systems.
4476 Also, include <sys/sysctl.h>, as it should be available on all
4477 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4478 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4479 use p_pid member, not kp_proc.pid.
4481 2012-07-06 Glenn Morris <rgm@gnu.org>
4483 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.

4487 More xmalloc and related cleanup.
4488 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
4489 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
4490 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

4496 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4498 Omit needless casts involving void * pointers and allocation.
4499 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4500 as the former is more robust if P's type is changed.
4501 Prefer xzalloc to xmalloc + memset 0.
4502 Simplify malloc-or-realloc to realloc.
4503 Don't worry about xmalloc returning a null pointer.
4504 Prefer xstrdup to xmalloc + strcpy.
4505 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4507 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4508 alloca of a constant.
4510 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4512 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4513 hscroll is larger than the line width. Fixes long and futile
4514 looping inside extend_face_to_end_of_line (on a TTY) producing
4515 glyphs that are not needed and thrown away.
4517 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4519 * marker.c (set_marker_restricted_both): Simplify by using

4529 not defined (Bug#11768).
4530 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
4531 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
4532 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
4533 followed by gtk_box_set_homogeneous (Bug#11768).
4534 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4535 (update_theme_scrollbar_width, xg_create_scroll_bar):
4536 Use gtk_scrollbar_new (Bug#11768).
4537 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

4545 * xdisp.c (window_hscroll_limited): New function.
4546 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
4547 coordinates when window's hscroll is set to insanely large
4550 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
4552 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
4553 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
4555 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4558 * lisp.h (xzalloc): New prototype. Omit needless casts.
4559 * alloc.c (xzalloc): New function. Omit needless casts.

4611 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4613 * fileio.c (time_error_value): Check the right error number.
4614 Problem reported by Troels Nielsen in
4615 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
4617 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4619 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
4620 This should be fixed in a better way; see Eli Zaretskii in
4621 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
4622 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
4624 * fileio.c (time_error_value): Rename from special_mtime.
4625 The old name's problems were noted by Eli Zaretskii in
4626 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
4628 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
4629 This variable's comment says Emacs needs at least one GDB-visible
4630 symbol of type enum pvec_type, to work around GDB problems.
4631 The symbol's value doesn't matter.
4633 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
4634 that causes compilation to fail on pre-C99 compilers.
4636 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
4638 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
4639 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
4641 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4643 * buffer.c (init_buffer_once): Fix initialization of
4644 headers for buffer_defaults and buffer_local_symbols.
4645 Reported by Juanma Barranquero <lekktu@gmail.com>.
4647 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
4649 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
4650 * lisp.h (enum pvec_type): Use fewer bits.
4651 (PSEUDOVECTOR_SIZE_BITS): New constant.
4652 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
4653 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
4654 change in pvec_type.
4655 (PSEUDOVECTOR_TYPEP): New macro.
4656 (TYPED_PSEUDOVECTORP): Use it.
4657 * fns.c (internal_equal): Adapt code to extract pvectype.
4658 * emacs.c (gdb_pvec_type): Update type.
4659 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
4660 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
4661 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
4662 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
4663 (sweep_vectors): Use it. Use local var `total_bytes' instead of
4664 abusing vector->header.next.nbytes.
4665 (live_vector_p): Use PVEC_TYPE.
4666 (mark_object): Adapt code to extract pvectype. Use switch.
4668 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4670 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
4671 Tighten new eassert a bit.
4673 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4675 Fix compilation with --enable-gcc-warnings and -O1
4677 * doprnt.c (doprnt): Change type of tem to int, initialize
4678 to avoid compiler warning. Add eassert.
4679 * search.c (simple_search): Initialize match_byte to avoid
4680 compiler warning. Add eassert.
4682 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4684 Avoid weird behavior with large horizontal scrolls.
4685 Without this change, for example, large hscroll values would
4686 mess up Emacs's display on Fedora 15 x86, presumably due to
4687 overflows in int calculations in the display code.
4688 Also, if buffers had long lines, Emacs would freeze.
4689 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
4690 (set_window_hscroll): New function, containing the old guts of
4691 Fset_window_hscroll. Return the clipped value.
4692 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
4693 This avoids the need to check against PTRDIFF_MAX.
4695 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
4697 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4699 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
4701 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4703 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
4704 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
4705 since GCC 4.4.6 issues a bogus warning for them.
4707 Fix bugs in file timestamp newness comparisons.
4708 * fileio.c (Ffile_newer_than_file_p):
4709 * lread.c (Fload): Use full timestamp resolution of files,
4710 not just the 1-second resolution, so that files that are only
4711 slightly newer still count as newer.
4712 * fileio.c (Ffile_newer_than_file_p): Don't assume file
4713 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
4715 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
4717 * fileio.c: Improve handling of file time marker. (Bug#11852)
4718 (special_mtime): New function.
4719 (Finsert_file_contents, Fverify_visited_file_modtime):
4720 Use it to set special mtime values consistently.
4722 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
4724 * fileio.c (Finsert_file_contents): Properly handle st_mtime
4725 marker for non-existing file. (Bug#11852)
4727 2012-07-03 Glenn Morris <rgm@gnu.org>
4729 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
4730 and did not make it into globals.h).
4732 2012-07-03 Tom Tromey <tromey@redhat.com>
4734 * window.c (Fset_window_margins, Fset_window_fringes)
4735 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
4736 * textprop.c (Fprevious_property_change): No longer static.
4737 * syntax.c (Fsyntax_table_p): No longer static.
4738 * process.c (Fget_process, Fprocess_datagram_address): No longer

4753 * composite.c (Fcomposition_get_gstring): No longer static.
4754 * callproc.c (Fgetenv_internal): No longer static.
4756 * ccl.h: Remove EXFUNs.
4757 * buffer.h: Remove EXFUNs.
4758 * dispextern.h: Remove EXFUNs.
4759 * intervals.h: Remove EXFUNs.
4760 * fontset.h: Remove EXFUN.
4761 * font.h: Remove EXFUNs.
4762 * dosfns.c (system_process_attributes): Remove EXFUN.
4763 * keymap.h: Remove EXFUNs.
4764 * lisp.h: Remove EXFUNs.
4765 * w32term.h: Remove EXFUNs.
4766 * window.h: Remove EXFUNs.
4767 * xsettings.h: Remove EXFUN.
4768 * xterm.h: Remove EXFUN.
4770 2012-07-03 Glenn Morris <rgm@gnu.org>
4772 * lisp.h (Frandom): Make it visible to C.
4773 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
4774 buffer for invisible buffers. (Bug#1229)
4776 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4778 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
4779 values which aren't power of 2.
4780 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
4781 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
4784 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
4786 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
4788 * alloc.c (mark_object): Revert part of last patch to use `switch'.
4790 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4792 * alloc.c (allocate_vector_block): Remove redundant
4793 calls to mallopt if DOUG_LEA_MALLOC is defined.
4794 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
4795 avoid calls to mallopt if zero_vector is returned.
4797 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4799 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
4800 is enabled, avoid dereferencing NULL current_sblock if
4803 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4805 Cleanup basic buffer management.
4806 * buffer.h (struct buffer): Change layout to use generic vector
4807 marking code. Fix some comments. Change type of 'clip_changed'
4808 to bitfield. Remove unused #ifndef old.
4809 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
4810 (GET_OVERLAYS_AT): Fix indentation.
4811 (for_each_per_buffer_object_at): New macro.
4812 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

4814 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
4815 * alloc.c (allocate_buffer): Adjust to match new layout of
4816 struct buffer. Fix comment.
4817 (mark_overlay): New function.

4819 Lisp area of struct buffer.
4820 (mark_object): Use it. Adjust marking of misc objects
4821 and related comments.
4823 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
4825 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
4826 wrapper that is not needed because the wrapped code is a no-op (zero
4827 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
4828 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
4830 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
4832 * alloc.c (mark_buffer): Simplify. Remove prototype.
4833 (mark_object): Add comment. Reorganize marking of vector-like
4834 objects. Use CHECK_LIVE for all vector-like objects except buffers
4835 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
4836 Avoid redundant calls to mark_vectorlike for bool vectors.
4838 2012-06-30 Glenn Morris <rgm@gnu.org>
4840 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
4842 * epaths.in (PATH_SITELOADSEARCH): New.
4843 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
4844 This is rather than relying on --enable-locallisppath elements
4845 having "site-lisp" in their names. (Bug#10208#25, 11658)
4847 2012-06-30 Eli Zaretskii <eliz@gnu.org>
4849 * w32proc.c (sys_select): Accept and ignore one more argument.
4851 * w32.c (emacs_gnutls_pull): Call select with one more argument.
4853 * sysselect.h [DOS_NT]: Don't include sys/select.h.
4854 (pselect) [!MS_DOS]: Redirect to sys_select.
4856 * sysdep.c: Don't include dos.h and dosfns.h.
4858 * process.c (sys_select):
4859 * msdos.c (sys_select): Accept one more argument and ignore it.
4861 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
4862 adapt data types and code to that.
4865 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
4866 which clashes with the gnulib function of the same name.
4868 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
4870 * font.c (font_style_to_value, font_style_symbolic)
4871 (font_prop_validate_style): Add type checks for values in
4874 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
4876 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
4879 2012-06-29 Eli Zaretskii <eliz@gnu.org>
4881 * xdisp.c (try_window_id): Undo last change.
4883 * w32.c (getwd): Adjust commentary about startup_dir.
4884 (init_environment): Always call sys_access, even in non-MSVC
4885 builds. Don't chdir to the directory of the Emacs executable.
4886 This undoes code from 1997 which was justified by the need to
4887 "avoid conflicts when removing and renaming directories". But its
4888 downside was that every relative file name was being interpreted
4889 relative to the directory of the Emacs executable, which can never
4890 be TRT. In particular, it broke sys_access when called with
4891 relative file names.
4892 (sys_access): Map GetLastError to errno.
4894 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4896 * window.h (struct window): Change type of 'fringes_outside_margins'
4897 to bitfield. Fix comment. Adjust users accordingly.

4900 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
4903 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
4905 * gnutls.c (emacs_gnutls_handshake):
4906 Add QUIT to make the loop interruptible.
4908 2012-06-29 Glenn Morris <rgm@gnu.org>
4910 * charset.c (init_charset): Make lack of etc/charsets fatal.
4912 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4914 * editfns.c (region_limit): Fix type mismatch.
4916 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4918 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
4919 undefined. Convert from xassert to eassert.
4920 * nsmenu.m: Convert from xassert to eassert.
4921 * nsterm.m: Likewise.
4923 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
4925 * editfns.c (region_limit): Clip to narrowing (bug#11770).
4927 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
4929 Avoid integer overflow on scroll-left and scroll-right.
4930 * window.c (HSCROLL_MAX): New macro.
4931 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
4932 overflow when requested scroll falls outside ptrdiff_t range.
4934 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
4936 * window.h (struct window): Change type of 'hscroll',
4937 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
4938 'last_modified' and 'last_overlay_modified' to EMACS_INT.
4939 Adjust users accordingly.
4940 * xdisp.c (try_cursor_movement): Replace type check with eassert.
4941 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
4942 from EMACS_INT to ptrdiff_t.
4943 (make_window): Omit redundant initialization.
4945 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
4947 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
4949 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
4951 * window.h (struct window): Change type of 'use_time' and
4952 'sequence_number' from Lisp_Object to int.
4953 * frame.c (make_frame): Adjust users accordingly.
4954 * print.c (print_object): Likewise.
4955 * window.c (select_window, Fwindow_use_time, make_parent_window)
4956 (make_window): Likewise.
4958 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
4960 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
4961 enabled with --enable-checking=[all,glyphs] configure option.

5086 Use sprintf return value instead of invoking strlen on result.
5087 In the old days this wasn't portable, since some sprintf
5088 implementations returned char *. But they died out years ago and
5089 Emacs already assumes sprintf returns int.
5090 Similarly for float_to_string.
5091 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

5100 * data.c (Fnumber_to_string):
5101 Use make_unibyte_string, since the string must be ASCII.
5102 * lisp.h, print.c (float_to_string): Now returns int length.
5103 * term.c (produce_glyphless_glyph):
5104 Use sprintf result rather than recomputing it.

5275 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5277 Support higher-resolution time stamps (Bug#9000).
5278 The time stamps are only nanosecond-resolution at the C level,
5279 since that's the best that any real-world system supports now.
5280 But they are picosecond-resolution at the Lisp level, as that's
5281 easy, and leaves room for future OS improvements.
5283 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5286 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5287 Don't get current time unless it's needed.
5289 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5290 now provides it if it's absent.
5291 (start_atimer): Port to higher-res time stamps.
5292 Check for time stamp overflow. Don't get current time more
5293 often than is needed.
5295 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5296 Include systime.h, not time.h.
5297 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
5299 * dired.c: Include stat-time.h.
5300 (Ffile-attributes): File times now have higher resolution.

5303 (struct image): Timestamp now has higher resolution.
5305 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5306 has at least microseconds now. All uses removed.
5307 (update_frame, update_single_window, update_window, update_frame_1)
5308 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5309 (duration_to_sec_usec): Remove; no longer needed.
5311 * editfns.c (time_overflow): Now extern.
5312 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

5317 (decode_time_components, lisp_seconds_argument): New functions.
5318 (make_time): Now static.
5319 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
5320 Report an error if the time is invalid, rather than having the caller
5323 * fileio.c: Include <stat-time.h>
5324 (Fcopy_file): Copy higher-resolution time stamps.
5325 Prefer to set the time stamp via a file descriptor if that works.
5326 (Fset_file_times, Finsert_file_contents, Fwrite_region)
5327 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
5328 (Fvisited_file_modtime, Fset_visited_file_modtime):
5329 Support higher-resolution time stamps.
5331 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
5333 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
5335 * image.c (prepare_image_for_display, clear_image_cache)
5336 (lookup_image): Port to higer-resolution time stamps.
5338 * keyboard.c (start_polling, bind_polling_period):
5339 Check for time stamp overflow.
5340 (read_char, kbd_buffer_get_event, timer_start_idle)
5341 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
5342 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5343 Port to higher-resolution time stamps. Do not assume time_t is signed.
5344 (decode_timer): New function. Timers are now vectors of length 9,
5345 not 8, to accommodate the picosecond component.
5346 (timer_check_2): Use it.
5348 * nsterm.m (select_timeout, timeval_subtract): Remove.
5349 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5350 as they're a bit more accurate and handle overflow better.
5351 (ns_select): Change prototype to be compatible with pselect.
5352 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5353 * nsterm.h (ns_select): Adjust prototype.
5355 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5356 us-resolution time stamps.
5357 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5359 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5361 * lisp.h (time_overflow): New decl.
5362 (wait_reading_process_output): First arg is now intmax_t, not int,
5363 to accommodate larger waits.
5365 * process.h (struct Lisp_Process.read_output_delay):
5366 Now counts nanoseconds, not microseconds.
5367 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
5369 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
5370 (wait_reading_process_output):
5371 Port to ns-resolution time stamps.
5372 (Faccept_process_output, wait_reading_process_output):
5373 Check for time stamp overflow. Do not assume time_t is signed.
5374 (select_wrapper): Remove; we now use pselect.
5375 (Fprocess_attributes): Now generates ns-resolution time stamps.
5377 * sysdep.c: Include utimens.h. Don't include utime.h
5378 or worry about struct utimbuf; gnulib does that for us now.
5379 (gettimeofday): Remove; gnulib provides a substitute.
5380 (make_timeval): New function.
5381 (set_file_times): Now sets ns-resolution time stamps.
5382 New arg FD; all uses changed.
5383 (time_from_jiffies, ltime_from_jiffies, get_up_time)
5384 (system_process_attributes):
5385 Now returns ns-resolution time stamp. All uses changed.
5386 Check for time stamp overflow.
5388 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5389 provides a substitute now.
5391 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5392 since it guarantees struct timespec.
5393 (EMACS_TIME): Now struct timespec, so that we can support
5394 ns-resolution time stamps.
5395 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5396 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5397 (EMACS_USECS): Remove.
5398 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5399 so multiply the arg by 1000 before storing it.
5400 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
5402 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
5403 Port to ns-resolution time stamps.
5404 (EMACS_TIME_NEG_P): Remove; replaced by....
5405 (EMACS_TIME_SIGN): New macro.
5406 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
5407 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

5409 (make_timeval, make_lisp_time, decode_time_components): New decls.
5410 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
5411 that it mishandled time_t overflow. You can't compare by subtracting!
5412 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
5413 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
5415 * term.c: Include <sys/time.h>.
5416 (timeval_to_Time): New function, for proper overflow wraparound.
5417 (term_mouse_position, term_mouse_click): Use it.
5419 * undo.c (record_first_change): Support higher-resolution time stamps
5421 (Fprimitive_undo): Use them when restoring time stamps.
5423 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
5424 (w32_get_internal_run_time):
5425 Port to higher-resolution Emacs time stamps.
5426 (ltime): Now accepts single 64-bit integer, as that's more convenient
5429 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
5431 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
5432 for compatibility with pselect. Support ns-resolution time stamps.
5434 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
5436 * xselect.c (wait_for_property_change, x_get_foreign_selection):
5437 Check for time stamp overflow, and support ns-resolution time stamps.
5439 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
5440 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
5441 (timeval_subtract): Remove; no longer needed.
5442 (XTflash, XTring_bell, x_wait_for_event):
5443 Port to ns-resolution time stamps. Don't assume time_t is signed.

5452 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5453 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,

5505 gets killed during executing of this function (Bug#11665).
5506 Try to always return Qt when the buffer has been actually killed.

5533 This removes the need for CHECK.
5534 (CHECK): Remove. Its comments about always evaluating its
5535 argument were confusing, as 'eassert' typically does not evaluate
5538 * coding.c (produce_chars): Use ptrdiff_t, not int.
5540 * xterm.c (x_draw_underwave): Check for integer overflow.
5541 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

5726 code works fine either way, and efficiency is not a concern here,
5727 as the union type is for debugging, not for production.
5728 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
5729 Use an inline function on all platforms when using the union type,
5730 since this is simpler and 'static inline' can be used portably

5874 * doprnt.c (doprnt): Truncate multibyte char correctly.
5875 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
5876 would mishandle a string argument "Xc" if X was a multibyte
5877 character of length 2: it would truncate after X's first byte
5878 rather than including all of X.

5924 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
5925 and DEFVAR it. Update all users.
5927 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5929 * minibuf.c (Fassoc_string): Remove duplicate declaration.
5931 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
5932 Convert pctcpu and pctmem to Lisp float properly.
5933 Let the compiler fold better, as 100.0/0x8000 is exact.
5935 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
5937 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
5940 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
5942 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
5944 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
5946 For a 'struct window', replace some Lisp_Object fields to
5947 bitfields where appropriate, remove unused fields.
5948 * window.h (struct window): Remove unused 'last_mark_x' and
5949 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
5950 change it's type from Lisp_Object to bitfield.
5951 Change type of 'force_start', 'optional_new_start',
5952 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
5953 fields from Lisp_Object to bitfield. Adjust users accordingly.
5955 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5957 Pacify gcc -Wdouble-precision when using Xaw.
5958 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
5959 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
5960 Use 'float' consistently, rather than 'float' in most places
5961 and 'double' in a couple of places.
5963 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5965 * xdisp.c (handle_stop): Detect whether we have overlay strings
5966 loaded by testing it->current.overlay_string_index to be
5967 non-negative, instead of checking whether n_overlay_strings is
5968 positive. (Bug#11587)
5970 2012-05-31 Chong Yidong <cyd@gnu.org>
5972 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
5974 * doc.c (Fsubstitute_command_keys): Doc fix.
5976 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5978 * search.c (search_buffer): Remove calls to
5979 r_alloc_inhibit_buffer_relocation, as it is now called by
5980 maybe_unify_char, which was the cause of relocation of buffer text
5983 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5985 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
5986 for the duration of call to load_charset, to avoid problems with
5987 callers of maybe_unify_char that access buffer text through C
5990 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
5991 decrement the inhibition flag, instead of just setting or
5994 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5996 Remove obsolete '#define static' cruft.
5997 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
5998 This #undef was "temporary" in 2000; it is no longer needed
5999 now that '#define static' has gone away.
6000 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6001 (gray_bitmap_bits): Remove; no longer needed.
6002 All uses replaced with definiens.
6003 * xterm.c: Include "bitmaps/gray.xbm".
6005 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6007 Clean up __executable_start, monstartup when --enable-profiling.
6008 The following changes affect the code only when profiling.
6009 * dispnew.c (__executable_start): Rename from safe_bcopy.
6010 Define only on platforms that need it.
6011 * emacs.c: Include <sys/gmon.h> when profiling.
6012 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6013 (__executable_start): Remove decl, since lisp.h does it now.
6014 (safe_bcopy): Remove decl; no longer has that name.
6015 (main): Coalesce #if into single bit of code, for simplicity.
6016 Cast pointers to uintptr_t, since standard libraries want integers
6018 * lisp.h (__executable_start): New decl.
6020 2012-05-31 Glenn Morris <rgm@gnu.org>
6022 * image.c (Fimagemagick_types): Doc fix.
6024 2012-05-30 Jim Meyering <meyering@redhat.com>
6026 * callproc.c (Fcall_process_region): Include directory component
6027 in mkstemp error message (Bug#11586).
6029 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6031 * alloc.c, lisp.h (make_pure_vector): Now static.
6033 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

6038 * data.c (Fdefalias): Purify definition, except for keymaps.
6039 (Qdefun): Move from eval.c.
6040 * lisp.h (Qdefun): Remove.
6041 * lread.c (read1): Tiny simplification.
6043 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
6045 Do not create empty overlays with the evaporate property (Bug#9642).
6046 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6047 Bug#9642, but explicitly check that the buffer the overlay would
6048 be moved to is live and rearrange lines to make sure that errors
6049 will not put the overlay in an inconsistent state.
6050 (Fdelete_overlay): Cosmetics.
6052 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6054 * w32term.c (my_bring_window_to_top): New function.
6055 (x_raise_frame): Use handle returned by DeferWindowPos, which
6056 could be different from the original one.
6057 Call my_bring_window_to_top instead of my_set_foreground_window.
6060 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6061 by calling BringWindowToTop.
6063 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6064 (WM_EMACS_END): Increase by one.
6066 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6068 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6069 This avoids undefined behavior that might cause the eassert
6070 to not catch an out-of-range value.
6072 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6074 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
6075 Update dependencies.
6077 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6079 * bidi.c (bidi_mirror_char): Fix last change.
6081 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
6083 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
6084 when referring to sectname field in printf format.
6086 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
6088 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6089 Only r_alloc_inhibit_buffer_relocation needed to be added;
6090 the others were already declared.
6092 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6093 before checking whether it's out of range. Put the check inside
6095 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6097 2012-05-27 Ken Brown <kbrown@cornell.edu>
6099 * callproc.c (Fcall_process): Restore a line that was accidentally
6100 commented out in the 2011-02-13 change (bug#11547).
6102 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6104 * lisp.h [REL_ALLOC]: Add prototypes for external functions
6105 defined on ralloc.c.
6107 * buffer.c [REL_ALLOC]: Remove prototypes of
6108 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
6109 they are now on lisp.h.
6111 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6113 * search.c (search_buffer): Use it to inhibit relocation of buffer
6114 text while re_search_2 is doing its job, because re_search_2 is
6115 passed C pointers to buffer text. (Bug#11519)
6117 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6120 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6121 state after an additional call to move_it_in_display_line_to, keep
6122 the values of it->max_ascent and it->max_descent found for the
6124 (pos_visible_p): Revert the comparison against bottom_y to what it
6125 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
6128 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6130 Fix coding-related core dumps with gcc -ftrapv.
6131 The code was computing A - B, where A and B are pointers, and B is
6132 random garbage. This can lead to core dumps on platforms that
6133 have special pointer registers, and it also leads to core dumps on
6134 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6135 A - B only when B is initialized properly.
6136 * coding.c (coding_set_source, coding_set_destination): Return void.
6137 (coding_change_source, coding_change_destinations): New functions,
6138 with the old behaviors of coding_set_source and coding_set_destination.
6139 All callers that need an offset changed to use these new functions.
6141 2012-05-26 Glenn Morris <rgm@gnu.org>
6143 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
6145 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6147 Extend mouse support on W32 text-mode console.
6148 * xdisp.c (draw_row_with_mouse_face):
6149 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6151 * w32console.c: Include window.h.
6152 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6154 (initialize_w32_display): Initialize mouse-highlight data.
6156 * w32inevt.c: Include termchar.h and window.h.
6157 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6158 moves, call note_mouse_highlight. If help_echo changed, call
6159 gen_help_event to produce help-echo message in the echo area.
6160 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6163 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6165 * lread.c (read1): Simplify slightly to avoid an overflow warning
6166 with GCC 4.7.0 on x86-64.
6168 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6170 * bidi.c (bidi_mirror_char): Revert last change: an int is
6171 definitely wide enough here.
6173 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
6175 Fix integer width and related bugs (Bug#9874).
6176 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
6177 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
6178 (string_bytes, check_sblock, allocate_string_data):
6179 (compact_small_strings, Fmake_bool_vector, make_string)
6180 (make_unibyte_string, make_multibyte_string)
6181 (make_string_from_bytes, make_specified_string)
6182 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
6183 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
6185 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6186 (allocate_pseudovector):
6187 Use int, not EMACS_INT, where int is wide enough.
6188 (inhibit_garbage_collection, Fgarbage_collect):
6189 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6190 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
6191 int might not be wide enough.
6192 (bidi_cache_search, bidi_cache_find, bidi_init_it)
6193 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6194 (bidi_at_paragraph_end, bidi_find_paragraph_start)
6195 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
6196 (bidi_level_of_next_char, bidi_move_to_visually_next):
6197 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6198 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
6199 (Fkill_buffer, Fset_buffer_major_mode)
6200 (advance_to_char_boundary, Fbuffer_swap_text)
6201 (Fset_buffer_multibyte, overlays_at, overlays_in)
6202 (overlay_touches_p, struct sortvec, record_overlay_string)
6203 (overlay_strings, recenter_overlay_lists)
6204 (adjust_overlays_for_insert, adjust_overlays_for_delete)
6205 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
6206 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
6207 (Foverlay_recenter, last_overlay_modification_hooks_used)
6208 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6209 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6210 (validate_region): Omit unnecessary test for b <= e,
6211 since that's guaranteed by the previous test.
6212 (adjust_overlays_for_delete): Avoid pos + length overflow.
6213 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6214 (report_overlay_modification):
6215 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6216 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
6217 Omit pointer cast, which isn't needed anyway, and doesn't work
6218 after the EMACS_INT -> ptrdiff_t change.
6219 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
6220 * buffer.h: Adjust decls to match defn changes elsewhere.
6221 (struct buffer_text, struct buffer):
6222 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6223 Use EMACS_INT, not int, where int might not be wide enough.
6224 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
6225 not int, to avoid needless 32-bit limit on 64-bit hosts.
6226 (exec_byte_code): Use tighter memory-full test, one that checks
6227 for alloca overflow. Don't compute the address of the object just
6228 before an array, as that's not portable. Use EMACS_INT, not
6229 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
6230 * callint.c (Fcall_interactively):
6231 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6232 * callproc.c (call_process_kill, Fcall_process):
6233 Don't assume pid_t fits into an Emacs fixnum.
6234 (call_process_cleanup, Fcall_process, child_setup):
6235 Don't assume pid_t fits into int.
6236 (call_process_cleanup, Fcall_process, delete_temp_file)
6237 (Fcall_process_region):
6238 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6239 (Fcall_process): Simplify handling of volatile integers.
6240 Use int, not EMACS_INT, where int will do.
6241 * casefiddle.c (casify_object, casify_region, operate_on_word)
6242 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
6243 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6244 (casify_object): Avoid integer overflow when overallocating buffer.
6245 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
6246 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
6247 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
6248 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6249 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6250 integers are now checked earlier. All uses replaced with XINT.
6252 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6253 For CCL_MapSingle, check that content and value are in int range.
6254 (ccl_driver, Fregister_code_conversion_map):
6255 Check that Vcode_version_map_vector is a vector.
6256 (resolve_symbol_ccl_program): Check that vector header is in range.
6257 Always copy the vector, so that we can check its contents reliably
6258 now rather than having to recheck each instruction as it's being
6259 executed. Check that vector words fit in 'int'.
6260 (ccl_get_compiled_code, Fregister_ccl_program)
6261 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6262 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
6263 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
6264 contents are in range.
6265 (Fccl_execute_on_string): Check that status is in range.
6266 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
6267 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
6268 Accept and return EMACS_INT, not int, because callers can pass values
6270 (c_string_width, strwidth, lisp_string_width, chars_in_text)
6271 (multibyte_chars_in_text, parse_str_as_multibyte)
6272 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
6273 (str_as_unibyte, str_to_unibyte, string_count_byte8)
6274 (string_escape_byte8, Fget_byte):
6275 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6276 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
6277 avoid mishandling large integers.
6278 * character.h: Adjust decls to match defn changes elsewhere.
6279 * charset.c (load_charset_map_from_file, find_charsets_in_text)
6280 (Ffind_charset_region):
6281 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6282 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
6283 (load_charset_map_from_vector, Fdefine_charset_internal):
6284 Don't assume fixnum fits in int.
6285 (load_charset_map_from_vector, Fmap_charset_chars):
6286 Remove now-unnecessary CHECK_NATNUMs.
6287 (Fdefine_charset_internal): Check ranges here, more carefully.
6288 Don't rely on undefined behavior with signed left shift overflow.
6289 Don't assume unsigned int fits into fixnum, or that fixnum fits
6290 into unsigned int. Don't require max_code to be a valid fixnum;
6291 that's not true for gb10830 4-byte on a 32-bit host. Allow
6292 invalid_code to be a cons, for the same reason. Require code_offset
6293 to be a character. Avoid int overflow if max_char is close
6295 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
6296 this is intended anyway and avoids some undefined behavior.
6297 (load_charset_map): Pass unsigned, not int, as 2nd arg of
6298 INDEX_TO_CODE_POINT, as that's what it expects.
6299 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
6300 * charset.h (DECODE_CHAR): Return int, not unsigned;
6301 this is what was intended anyway, and it avoids undefined behavior.
6302 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
6303 integer-overflow issues.
6304 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
6305 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
6306 where the argument is EMACS_INT, and this behavior is not intended.
6307 * chartab.c (Fmake_char_table, Fset_char_table_range)
6308 (uniprop_get_decoder, uniprop_get_encoder):
6309 Don't assume fixnum fits in int.
6310 * cmds.c (move_point): New function, that does the gist of
6311 Fforward_char and Fbackward_char, but does so while checking
6312 for integer overflow more accurately.
6313 (Fforward_char, Fbackward_char): Use it.
6314 (Fforward_line, Fend_of_line, internal_self_insert)
6315 (internal_self_insert):
6316 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6317 Fix a FIXME, by checking for integer overflow when calculating
6318 target_clm and actual_clm.
6319 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
6320 (CODING_ENCODE_CHAR, CODING_CHAR_CHARSET, CODING_CHAR_CHARSET_P)

7058 * xfns.c (x_in_use): Remove `static' qualifier.
7059 * xterm.h (x_in_use): Declare.
7060 * xgselect.c: Include xterm.h.
7061 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
7062 and `display_arg' (bug#9754).
7064 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
7066 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
7068 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
7069 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
7071 2012-05-18 Eli Zaretskii <eliz@gnu.org>
7073 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
7075 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
7076 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
7078 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
7079 reference to image_cache->refcount.
7080 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
7082 2012-05-17 Juri Linkov <juri@jurta.org>
7084 * search.c (Fword_search_regexp, Fword_search_backward)
7085 (Fword_search_forward, Fword_search_backward_lax)
7086 (Fword_search_forward_lax): Move functions to isearch.el
7087 (bug#10145, bug#11381).
7089 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
7091 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
7093 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
7095 * lread.c (init_obarray): Declare Qt and Qnil as special.
7097 2012-05-14 Glenn Morris <rgm@gnu.org>
7099 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
7100 Put "libexec" before "bin", for the sake of init_callproc_1.
7102 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7104 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
7106 * unexaix.c: Port to more-recent AIX compilers.
7107 (report_error, report_error_1, make_hdr, copy_sym)
7108 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
7109 Make arguments const char *, not char *, to avoid violations of C
7110 standard and to fix some AIX warnings reported by Gilles Pion.
7112 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7114 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
7115 already have overlays loaded.
7116 (handle_single_display_spec): Before returning without displaying
7117 fringe bitmap, synchronize the bidi iterator with the main display
7118 iterator, by calling iterate_out_of_display_property.
7119 (iterate_out_of_display_property): Detect buffer iteration by
7120 testing that it->string is a Lisp string.
7121 (get_next_display_element): When the current object is exhausted,
7122 and there's something on it->stack, call set_iterator_to_next to
7123 proceed with what's on the stack, instead of returning zero.
7124 (set_iterator_to_next): If called at the end of a Lisp string,
7125 proceed to consider_string_end without incrementing string
7126 position. Don't increment display vector index past the end of
7127 the display vector. (Bug#11417)
7128 (pos_visible_p): Don't report a position visible when move_it_to
7129 stopped at the last line of window, which happens to be scanned
7130 backwards by the bidi iteration. (Bug#11464)
7132 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7134 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7135 and right-margin display specs even if the spec is invalid or we
7136 are on a TTY, and thus unable to display on the fringes.
7137 That's because the text with the property will not be displayed anyway,
7138 so we need to signal to the caller that this is a "replacing"
7139 display spec. This fixes display when the spec is invalid or we
7142 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7144 * unexaix.c (make_hdr): Fix typo in prototype.
7145 This bug broke the build on AIX. Problem reported by Gilles Pion.
7147 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
7149 * keyboard.c (kbd_buffer_get_event): Read special events also in
7150 batch mode. (Bug#11415)
7152 2012-05-12 Glenn Morris <rgm@gnu.org>
7154 * ns.mk: Update for ns_appbindir no longer having trailing "/".
7156 2012-05-12 Eli Zaretskii <eliz@gnu.org>
7158 * lisp.mk (lisp): Add newcomment.elc.
7160 2012-05-12 Glenn Morris <rgm@gnu.org>
7162 * Makefile.in (MKDIR_P): New, set by configure.
7163 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
7165 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
7167 Remove unused function hourglass_started.
7168 * dispextern.h (hourglass_started):
7169 * w32fns.c (hourglass_started):
7170 * xdisp.c (hourglass_started): Remove.
7172 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7174 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7175 Update dependencies.
7177 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7179 * xgselect.c (xg_select): Put maxfds+1 into a var.
7180 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
7182 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7184 2012-05-10 Dave Abrahams <dave@boostpro.com>
7186 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7187 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7189 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7191 * dbusbind.c (xd_registered_buses): New internal Lisp object.
7192 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7193 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7194 Initialize xd_registered_buses.
7196 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7198 Untag more efficiently if USE_LSB_TAG.
7199 This is based on a proposal by YAMAMOTO Mitsuharu in
7200 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7201 For an admittedly artificial (nth 8000 longlist) benchmark on
7202 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7203 Emacs's overall text size by 1%.
7204 * lisp.h (XUNTAG): New macro.
7205 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7206 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7207 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7208 * eval.c (Fautoload):
7209 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7210 * frame.h (XFRAME): Use XUNTAG.
7212 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7213 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7214 Remove unportable assumptions about print widths of types like
7216 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7217 intptr_t when converting between pointer and integer, to avoid GCC
7218 warnings about wrong width.
7220 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7222 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7223 stack for each reader_thread, instead of defaulting to 8MB
7224 determined by the linker. This avoids failures in creating
7225 subprocesses on Windows 7, see the discussion in this thread:
7226 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7228 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7230 Fix up display of the *Minibuf-0* buffer in the mini window.
7231 * keyboard.c (read_char): Don't clear the echo area if there's no
7233 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7234 contents of *Minibuf-0*) if there's no message displayed in its stead.
7236 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7238 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7241 2012-05-06 Chong Yidong <cyd@gnu.org>
7243 * lisp.mk (lisp): Update.
7245 2012-05-05 Jim Meyering <meyering@redhat.com>
7247 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7249 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7251 * data.c (PUT_ERROR): New macro.
7252 (syms_of_data): Use it. Add new error type `user-error'.
7253 * undo.c (user_error): New function.
7254 (Fprimitive_undo): Use it.
7255 * print.c (print_error_message): Adjust print style for `user-error'.
7256 * keyboard.c (user_error): New function.
7257 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7259 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7261 Do not limit current-time-string to years 1000..9999.
7262 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7263 (Fcurrent_time_string): Support any year that is supported by the
7264 underlying localtime representation. Don't use asctime, as it
7265 has undefined behavior for years outside the range -999..9999.
7267 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7269 Fix race conditions involving setenv, gmtime, localtime, asctime.
7270 Without this fix, interrupts could mess up code that uses these
7271 nonreentrant functions, since setting TZ invalidates existing
7272 tm_zone or tzname values, and since most of these functions return
7273 pointers to static storage.
7274 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7275 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7276 Grow the critical sections to include not just invoking
7277 localtime/gmtime, but also accessing these functions' results
7278 including their tm_zone values if any, and any related TZ setting.
7279 (format_time_string): Last arg is now struct tm *, not struct tm **,
7280 so that the struct tm is saved in the critical section.
7281 All callers changed. Simplify allocation of initial buffer, partly
7282 motivated by the fact that memory allocation needs to be outside
7283 the critical section.
7285 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7287 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7288 with RESET_INTERVAL.
7290 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7291 Remove duplicated buffer name initialization.
7293 2012-05-02 Jim Meyering <jim@meyering.net>
7295 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7297 * xfns.c (x_window): Use xstrdup (Bug#11375).
7299 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7301 * xdisp.c (pos_visible_p): If already at a newline from the
7302 display string before the 'while' loop, don't walk back the glyphs
7303 from it3.glyph_row. Solves assertion violation when the display
7304 string begins with a newline (egg.el). (Bug#11367)
7306 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7308 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7311 2012-05-01 Glenn Morris <rgm@gnu.org>
7313 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7314 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7315 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7316 All were removed before 23.1.
7318 * dispnew.c: Remove HAVE_LIBNCURSES test;
7319 it is always true on relevant platforms.
7321 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7322 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7324 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
7326 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
7328 * .gdbinit (xpr): Remove checks for no longer existing misc types.
7329 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
7332 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
7334 Do not avoid creating empty evaporating overlays (Bug#9642).
7335 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7336 That is, do not delete an evaporating overlay if it becomes
7337 empty after its bounds are adjusted to fit within its buffer.
7338 This fix caused other problems, and I'm reverting it until we get
7339 to the bottom of them.
7341 2012-04-27 Chong Yidong <cyd@gnu.org>
7343 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7345 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7347 * xdisp.c (pos_visible_p): If the window start position is beyond
7348 ZV, start the display from buffer beginning. Prevents assertion
7349 violation in init_iterator when the minibuffer window is scrolled
7352 * window.c (window_scroll_pixel_based): Likewise.
7354 2012-04-27 Chong Yidong <cyd@gnu.org>
7356 * keymap.c (where_is_internal): Doc fix (Bug#10872).
7358 2012-04-27 Glenn Morris <rgm@gnu.org>
7360 * fileio.c (Fcopy_file, Fset_file_selinux_context):
7361 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
7363 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7365 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
7366 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
7368 2012-04-26 Eli Zaretskii <eliz@gnu.org>
7370 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7371 display element, check also the underlying string or buffer
7372 character. (Bug#11341)
7374 * w32menu.c: Include w32heap.h.
7375 (add_menu_item): If the call to AppendMenuW (via
7376 unicode_append_menu) fails, disable Unicode menus only if we are
7377 running on Windows 9X/Me.
7379 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7381 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
7382 (xgetint): Add missing shift for LSB tags.
7384 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7386 * keyboard.c (read_char): Don't wipe echo area for select window
7387 events: These might get delayed via `mouse-autoselect-window'
7390 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
7392 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
7393 manipulation of :loaded-from data.
7395 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
7397 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
7398 now a cons (bug#11311).
7400 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7402 Do not create empty overlays with the evaporate property (Bug#9642).
7403 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7404 if it becomes empty after its bounds are adjusted to fit within
7405 its buffer. Without this fix, in a nonempty buffer (let ((o
7406 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7407 yields an empty overlay that has the evaporate property, which is
7408 not supposed to happen.
7410 Fix minor GTK3 problems found by static checking.
7411 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7412 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7413 (struct _EmacsFixedClass, emacs_fixed_get_type):
7414 Move decls here from emacsgtkfixed.h, since they needn't be public.

7421 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
7422 (EMACS_FIXED_GET_CLASS): Remove; unused.
7423 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
7425 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
7426 Problem reported by Juanma Barranquero for Windows -Wunused-function.
7428 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7430 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
7431 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
7432 (__malloc_size_t, __malloc_ptrdiff_t):
7433 Remove. All uses removed, replaced by the definiens if needed,
7434 since we can assume C89 or better now.
7435 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
7436 (protect_malloc_state, align, get_contiguous_space)
7437 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

7443 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
7444 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
7445 Define using prototypes, not old style.
7446 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
7447 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
7448 (align): Don't assume that signed integer overflow wraps around.
7449 Omit unused local var.
7450 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
7451 (_free_internal_nolock, memalign, mallochook, reallochook):
7452 Omit no-longer-needed casts.
7453 (valloc): Use getpagesize, not __getpagesize.
7454 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
7455 (struct hdr): The 'magic' member is now size_t, not unsigned long.
7457 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
7459 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
7461 Move functions from C to Lisp. Make non-blocking method calls
7462 the default. Implement further D-Bus standard interfaces.

7504 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7506 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
7507 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
7508 Do not assume ptrdiff_t is the same width as 'int'.
7510 * alloc.c: Handle unusual debugging option combinations.
7511 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
7512 since the two debugging options are incompatible.
7513 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7515 (mem_init, mem_insert, mem_insert_fixup):
7516 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

7526 (list_system_processes, system_process_attributes) [__FreeBSD__]:
7527 Use Emacs indenting style more consistently. Avoid some casts.
7528 Use 'double' consistently rather than mixing 'float' and 'double'.

7546 * print.c (print_preprocess): Only check print_depth if print-circle
7548 (print_object): Check for cycles even when print-circle is nil and
7549 print-gensym is t, but only check print_depth if print-circle is nil.
7551 2012-04-20 Chong Yidong <cyd@gnu.org>
7553 * process.c (wait_reading_process_output): If EIO occurs on a pty,
7554 set the status to "failed" and ensure that sentinel is run.
7556 2012-04-20 Glenn Morris <rgm@gnu.org>

7567 row, return zero immediately.
7568 (try_cursor_movement): If inside continuation line, don't back up
7569 farther than the first row after the header line, if any.
7570 Don't consider the header-line row as "partially visible", even if
7571 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
7573 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

7608 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
7609 New extern decls, to avoid calling undeclared functions.
7610 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
7611 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
7612 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
7613 (NEED_MEM_INSERT): New macro.
7614 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
7615 Remove one incorrect comment and fix another.

7629 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
7630 Remove decls. This fixes an "It stinks!".

7634 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
7636 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

7649 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
7650 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
7651 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
7652 * s/netbsd.h, s/sol2-6.h:
7653 Remove definition of GC_MARK_STACK, since the default now works.
7654 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
7655 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
7656 no longer the default.
7657 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
7659 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
7661 * lread.c (lisp_file_lexically_bound_p):

7682 2012-04-11 Daniel Colascione <dancol@dancol.org>
7684 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
7685 against is gone. It's better to use vfork now so that when Cygwin
7686 gains a new, working vfork, we use it automatically (bug#10398).
7688 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

7706 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
7708 * w32.c (w32_delayed_load): Record the full path of the library
7709 being loaded (bug#10424).
7711 2012-04-09 Glenn Morris <rgm@gnu.org>
7713 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
7714 not just in the obarray, before snarfing them. (Bug#11036)
7716 * Makefile.in ($(leimdir)/leim-list.el):
7717 Pass EMACS rather than BUILT_EMACS.

7726 Add convenience `GNUTLS_LOG2i' macro.
7728 * gnutls.c (gnutls_log_function2i): Convenience log function.
7729 (emacs_gnutls_read): Use new log functions,
7730 `gnutls_handshakes_tried' process member, and

7741 * minibuf.c (Fread_variable): Callers changed.
7743 2012-04-09 Eli Zaretskii <eliz@gnu.org>
7745 * xdisp.c (set_cursor_from_row): If the display string appears in
7746 the buffer at position that is closer to point than the position
7747 after the display string, display the cursor on the first glyph of
7748 the display string. Fixes cursor display when a 'display' text
7749 property immediately follows invisible text. (Bug#11094)
7751 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
7753 composite.c: use 'double' consistently
7754 * composite.c (get_composition_id): Use 'double' consistently
7755 instead of converting 'float' to 'double' and vice versa; this is
7756 easier to understand and avoids a GCC warning.
7758 2012-04-09 Glenn Morris <rgm@gnu.org>
7760 * Makefile.in: Generate leim-list with bootstrap-emacs, in
7761 preparation for dumping it with emacs. (Bug#4789)

7783 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
7784 (mark_memory): Mark Lisp_Objects only if pointers might hide in
7785 objects, as mark_maybe_pointer will catch them otherwise.
7786 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
7787 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

7791 Fix typo that broke non-Windows builds.
7792 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

7803 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
7804 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
7805 [!WINDOWSNT]: New macros.
7806 (init_libxml2_functions, libxml2_loaded_p): New functions.
7807 (parse_region): Call fn_xmlCheckVersion instead of using the macro
7808 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
7809 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
7810 Calls xmlCleanupParser only if libxml2 was loaded (or statically
7812 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
7813 Call init_libxml2_functions before calling libxml2 functions.
7814 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
7816 * emacs.c: Don't include libxml/parser.h.
7817 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
7818 xmlCleanupParser directly.
7820 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
7822 2012-04-07 Eli Zaretskii <eliz@gnu.org>

7830 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
7831 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
7832 about subtle differences between FETCH_CHAR* and STRING_CHAR*
7833 macros related to unification of CJK characters. For the details,
7834 see the discussion following the message here:
7835 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
7837 2012-04-04 Chong Yidong <cyd@gnu.org>
7839 * keyboard.c (Vdelayed_warnings_list): Doc fix.
7841 2012-04-01 Eli Zaretskii <eliz@gnu.org>
7843 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

7851 2012-03-31 Eli Zaretskii <eliz@gnu.org>
7853 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
7854 position we get to after a call to move_it_to fails the
7855 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
7856 only if we wind up in a string from display property. (Bug#11063)
7858 * window.c (Fdelete_other_windows_internal): Invalidate the row
7859 and column information about mouse highlight, so that redisplay
7860 restores it after reallocating the glyph matrices. (Bug#7464)
7862 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
7863 string comes from a `display' text property, use the buffer
7864 position of that property as if we actually saw that position in
7866 (move_it_by_lines): Remove the assertion that
7867 "it->current_x == 0 && it->hpos == 0" which can be legitimately
7868 violated when there's a before-string at the beginning of a line.
7871 2012-03-30 Eli Zaretskii <eliz@gnu.org>
7873 * xdisp.c (append_space_for_newline): If the default face was
7874 remapped, use the remapped face for the appended newline.
7875 (extend_face_to_end_of_line): Use the remapped default face for
7876 extending the face to the end of the line.
7877 (display_line): Call extend_face_to_end_of_line when the default
7878 face was remapped. (Bug#11068)
7880 2012-03-29 Eli Zaretskii <eliz@gnu.org>

7902 handle-select-window too (Bug#8996).
7904 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
7906 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
7908 2012-03-25 Kenichi Handa <handa@m17n.org>
7910 * dispextern.h (struct glyph): Change the bit length of
7911 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
7913 2012-03-24 Eli Zaretskii <eliz@gnu.org>
7915 * s/ms-w32.h (tzname): Include time.h before redirecting to
7916 _tzname. Fixes the MSVC build. (Bug#9960)
7918 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
7920 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
7923 * xterm.c (XTread_socket): Only modify handling_signal if

7926 2012-03-23 Eli Zaretskii <eliz@gnu.org>
7928 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
7929 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
7930 when fetching a multibyte character consumes more bytes than
7931 CHAR_BYTES returns, due to unification of CJK characters in
7932 string_char. (Bug#11073)
7934 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
7936 * process.c (wait_reading_process_output): Handle pty disconnect
7937 by refraining from sending oneself a SIGCHLD (bug#10933).

7948 2012-03-21 Chong Yidong <cyd@gnu.org>
7950 * xfaces.c (Vface_remapping_alist): Doc fix.
7952 2012-03-20 Eli Zaretskii <eliz@gnu.org>
7954 * w32proc.c (Fw32_set_console_codepage)
7955 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

7966 it fit in a valid range (Bug#11003).
7968 2012-03-18 Eli Zaretskii <eliz@gnu.org>
7970 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
7971 that is not from display property, accept the row as a "cursor
7972 row" if one of the string's character has a non-nil `cursor'
7973 property. Fixes cursor positioning when there are newlines in
7974 overlay strings, e.g. in icomplete.el. (Bug#11035)
7976 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
7978 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
7980 2012-03-12 Chong Yidong <cyd@gnu.org>
7982 * eval.c (inhibit_lisp_code): Rename from

8007 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8010 2012-03-03 Glenn Morris <rgm@gnu.org>
8012 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

8025 * buffer.c (buffer-list-update-hook): Doc fix.
8027 2012-02-29 Eli Zaretskii <eliz@gnu.org>

8030 push_it before setting up the iterator for the first overlay
8031 string, even if we have an empty string loaded.
8032 (next_overlay_string): If there's an empty string on the iterator
8033 stack, pop the stack. (Bug#10903)
8035 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8037 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8038 Suggested by Stefan Monnier in
8039 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8040 * alloc.c (widen_to_Lisp_Object): New static function.
8041 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8042 and widening them to Lisp_Objects. This would work even if
8043 USE_LSB_TAG is defined and wide integers are used, which might
8044 happen in a future version of Emacs.
8046 2012-02-25 Chong Yidong <cyd@gnu.org>
8048 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

8063 call when setting menu-bar-lines and tool-bar-lines parameters.
8064 (unwind_create_frame_1): New helper function.
8066 * window.c (inhibit_window_configuration_change_hook): New var.
8067 (run_window_configuration_change_hook): Obey it.
8068 (syms_of_window): Initialize it.
8070 2012-02-22 Chong Yidong <cyd@gnu.org>
8072 * xterm.c (x_draw_image_relief): Add missing type check for

8085 when computing $valmask.
8087 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8088 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8089 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8090 It's useless in that case, and it can cause problems on hosts
8091 that allocate halves of EMACS_INT values separately.
8092 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8093 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8094 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8095 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8096 it avoids undefined behavior on hosts where shifting right by more
8097 than the word width has undefined behavior.
8099 2012-02-19 Chong Yidong <cyd@gnu.org>
8101 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
8102 (Funhandled_file_name_directory, Ffile_name_as_directory)

8121 2012-02-15 Chong Yidong <cyd@gnu.org>
8123 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
8124 marked as special. Also, starting docstrings with * is obsolete.

8142 as that creates a dangerous corner case.
8144 * window.c (Fdelete_window_internal): Invalidate the mouse
8145 highlight (Bug#9904).
8147 2012-02-12 Glenn Morris <rgm@gnu.org>

8177 2012-02-07 Chong Yidong <cyd@gnu.org>
8179 * buffer.c (Fbuffer_local_variables)
8180 (buffer_lisp_local_variables): Handle unbound vars correctly;
8181 don't let Qunbound leak into Lisp.
8183 2012-02-07 Glenn Morris <rgm@gnu.org>
8185 * image.c (Fimagemagick_types): Doc fix.
8187 * image.c (imagemagick-render-type): Change it from a lisp object

8220 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
8222 Handle overflow when computing char display width (Bug#9496).
8223 * character.c (char_width): Return EMACS_INT, not int.
8224 (char_width, c_string_width): Check for overflow when
8225 computing the width; this is possible now that individual
8226 characters can have unbounded width. Problem introduced
8227 by merge from Emacs 23 on 2012-01-19.
8229 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

8369 (Fmake_directory_internal): Use it.
8370 (do_auto_save_make_dir): Set it, instead of invoking chmod after

8372 too-generous permissions to the directory.
8373 (do_auto_save_eh): Clear it.
8374 (Fdo_auto_save): Catch all errors, not just file errors, so

8881 is set, removing the need for VIRT_ADDRESS_VARIES.

8885 to 4 (xorl, subq, cmpq, setbe).
8886 * alloc.c (pure): Always extern now, since that's the

8889 consistency with the new puresize.h.
8890 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

8899 behave as if the cursor position were at the window margin.
8901 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
8902 and the cursor position is out of bounds, behave as if the cursor
8903 position were at the window margin. (Bug#10075)
8905 2011-11-18 Chong Yidong <cyd@gnu.org>
8907 * window.c (Fwindow_combination_limit): Make first argument

8929 compute_line_metrics.
8930 (compute_line_metrics): Call row_hash, instead of computing the
8933 * dispnew.c (verify_row_hash): Call row_hash for computing the
8934 hash code of a row, instead of duplicating code from xdisp.c.
8936 * dispextern.h (row_hash): Add prototype.
8938 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
8940 * frame.c (delete_frame): Don't delete the terminal when the last

8965 (recombine_windows, make_parent_window, make_window)
8966 (Fsplit_window_internal, saved_window)
8967 (Fset_window_configuration, save_window_save): Rename all
8968 occurrences of window_nest to window_combination_limit.
8970 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
8972 * image.c (imagemagick_load_image): Fix typo.
8974 2011-11-14 Eli Zaretskii <eliz@gnu.org>
8976 * xdisp.c (display_line): Move the call to
8977 highlight_trailing_whitespace before the call to
8978 compute_line_metrics, since the latter needs to see the final

9446 * editfns.c: Rewrite current-time-zone so that it invokes
9447 the equivalent of (format-time-string "%Z") to get the time zone name.
9448 This fixes a bug when the time zone name contains characters that
9449 need converting from the system time locale to Emacs internal format.
9450 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9451 that patch fixed format-time-string to do the conversion, but
9452 I forgot to fix current-time-zone.
9453 (format_time_string): New function, containing most of
9454 what Fformat_time_string used to contain.
9455 (Fformat_time_string): Rewrite in terms of format_time_string.
9456 This doesn't change this function's behavior.
9457 (current-time-zone): Rewrite to use format_time_string.
9458 This fixes the bug reported by Michael Schierl in
9459 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9460 Jason Rumney's 2007-06-07 change worked around this bug, but
9462 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9464 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9466 * xdisp.c (start_display): If the character at POS is displayed
9467 via a display vector, reset IT->current.dpvec_index to zero.
9468 (try_window_reusing_current_matrix): If a line ends in a display
9469 vector or the next line starts in a display vector, continue
9470 redrawing the window even though the character position of
9471 start_row was reached.
9474 2011-10-18 Chong Yidong <cyd@gnu.org>
9476 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9477 with nobreak-char-display too.
9479 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9481 Fix part 3 of bug#9771.
9482 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9483 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9484 non-neutral characters if the current character is a paragraph
9485 separator (a.k.a. Newline). This avoids running the same
9486 expensive loop twice, once when we consume the preceding newline
9487 and the other time when the line actually needs to be displayed.
9488 Avoid the loop when we see neutrals on the base embedding level
9489 following a character whose directionality is the same as the
9490 paragraph's. This avoids running the expensive loop when a line
9491 ends in a long sequence of neutrals, like control characters.
9492 Add assertion against STRONG_AL type. Slightly rearrange code
9493 that determines the type of a neutral given the first non-neutral
9495 (bidi_level_of_next_char): Set next_en_pos to zero when
9496 invalidating its info.
9498 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9500 * xdisp.c (push_display_prop): Determine whether to record string
9501 or buffer position by IT->string, not by IT->method. Allow
9502 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9503 (move_it_vertically_backward): Don't look for character position
9504 immediately after the newline when in a continuation line.
9507 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9509 * window.c (coordinates_in_window): Rewrite and delabelize
9510 vertical border check. (Bug#5357) (Bug#9618)
9512 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9514 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9515 errors in XSetWindowBorder (bug#9310).
9517 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9519 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9520 avoid crash when xmalloc overrun checking is enabled.
9522 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9524 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9525 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9526 cursor motion with <left> and <right> arrow keys.
9528 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9529 some callers set that themselves.
9531 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9533 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9534 display string and the previous row comes from the same string and
9535 is empty. (Bug#9739) (Bug#9738)
9537 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9539 * doc.c (get_doc_string): Encode file name (bug#9735).
9541 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9543 * bidi.c (bidi_level_of_next_char):
9544 * xdisp.c (get_visually_first_element): Remove old incorrect
9545 comments regarding the Unicode Line Separator character.
9547 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9549 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9551 * alloc.c (Fgc_status): Do not access beyond zombies array
9552 boundary if nzombies > MAX_ZOMBIES.
9553 * alloc.c (dump_zombies): Add missing format specifier.
9555 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9557 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9558 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9560 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9561 Some packages use them to denote characters with modifiers.
9563 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9565 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9566 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9567 matching a pp-number. Rename parameter var to var1.
9569 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9571 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9573 2011-10-08 Glenn Morris <rgm@gnu.org>
9575 * callint.c (Fcall_interactively): Give a more explicit error for the
9576 'c' case with a non-character input. (Bug#8479)
9578 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9580 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9582 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9583 lines that are hscrolled on the left.
9585 * dispnew.c (buffer_posn_from_coords): Account for a possible
9586 presence of header-line. (Bug#4426)
9588 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
9590 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
9591 Don't advertise functionality which we discourage or doesn't work.
9593 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
9595 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
9596 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
9597 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
9598 this makes Emacs dump core during garbage collection on rare
9599 occasions. sizeof is obviously inferior to offsetof here, so
9600 stick with offsetof.
9601 (GC_POINTER_ALIGNMENT): New macro.
9602 (mark_memory): Omit 3rd (offset) arg; caller changed.
9603 Don't assume EMACS_INT alignment is the same as pointer alignment.
9605 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
9607 * keyboard.c (read_key_sequence_remapped): New var.
9608 (read_key_sequence): Compute remapping in the right buffer.
9609 (command_loop_1): Use read_key_sequence's remapping directly.
9611 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
9613 * dired.c (file_name_completion): Don't expand file name.
9614 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
9615 before checking file name handler.
9617 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
9618 they've been requested explicitly (bug#9591).
9620 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
9622 * keymap.c (Fsingle_key_description): Use make_specified_string
9623 instead of build_string to build string from push_key_description.
9626 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9628 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
9629 This fixes a Y2038 bug on 64-bit hosts.
9630 * buffer.c (reset_buffer):
9631 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
9632 (Fclear_buffer_auto_save_failure):
9633 Use 0, not -1, to represent an unset failure time, since time_t
9634 might not be signed.
9636 Remove dependency on glibc malloc internals.
9637 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9638 Move back here from lisp.h, but with their new implementations.
9639 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9640 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
9641 * charset.c (charset_table_init): New static var.
9642 (syms_of_charset): Use it instead of xmalloc. This removes a
9643 dependency on glibc malloc internals. See Eli Zaretskii's comment in
9644 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
9645 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9646 Move back to alloc.c.
9647 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9648 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
9650 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
9652 * nsterm.m (windowDidResize): Call x_set_window_size only when
9653 ns_in_resize is true. Otherwise set pixelwidth/height and
9654 call change_frame_size (Bug#9628).
9656 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9658 Port --enable-checking=all to Fedora 14 x86-64.
9659 * charset.c (syms_of_charset): Also account for glibc malloc's
9660 internal overhead when calculating the initial malloc maximum.
9662 Port --enable-checking=all to Fedora 14 x86.
9663 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9665 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
9666 (overrun_check_realloc, overrun_check_free):
9667 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
9668 That way, xmalloc returns a properly-aligned pointer even if
9669 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
9670 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
9671 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
9672 into account when calculating the initial malloc maximum.
9673 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9674 Move here from alloc.c, so that charset.c can use it too.
9675 Properly align; the old code wasn't right for common 32-bit hosts
9676 when configured with --enable-checking=all.
9677 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9678 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
9680 2011-09-29 Eli Zaretskii <eliz@gnu.org>
9682 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
9685 2011-09-28 Eli Zaretskii <eliz@gnu.org>
9687 * xdisp.c (compute_display_string_end): If there's no display
9688 string at CHARPOS, return -1.
9690 * bidi.c (bidi_fetch_char): When compute_display_string_end
9691 returns a negative value, treat the character as a normal
9692 character not covered by a display string. (Bug#9624)
9694 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
9696 * lread.c (Fread_from_string): Fix typo in docstring.
9698 2011-09-27 Eli Zaretskii <eliz@gnu.org>
9700 * xdisp.c (handle_invisible_prop): If invisible text ends on a
9701 newline, reseat the iterator instead of bidi-iterating there one
9702 character at a time. (Bug#9610)
9703 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
9704 TO_CHARPOS if the bidi iterator is at base embedding level.
9706 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
9708 * lread.c (readevalloop): Use correct code for NBSP.
9709 (read1): Likewise. (Bug#9608)
9711 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
9713 * dbusbind.c (Fdbus_register_signal): When service is not
9714 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
9716 2011-09-25 Glenn Morris <rgm@gnu.org>
9718 * buffer.c (truncate-lines): Doc fix.
9720 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
9722 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
9723 (Fset_window_next_buffers): Doc fix.
9725 2011-09-24 Glenn Morris <rgm@gnu.org>
9727 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
9729 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
9731 Fix minor problems found by static checking.
9732 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
9733 * indent.c (Fvertical_motion): Fix == vs = typo.
9735 2011-09-24 Eli Zaretskii <eliz@gnu.org>
9737 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
9738 Default value is now t. Doc fix.
9740 * indent.c (Fvertical_motion): Compute and apply the overshoot
9741 logic when moving up, not only when moving down. Fix the
9742 confusing name and values of the it_overshoot_expected variable;
9743 logic changes accordingly. (Bug#9254) (Bug#9549)
9745 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
9746 CHARPOS is covered by a display string which includes newlines.
9747 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
9748 is covered by a display string with embedded newlines.
9750 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
9752 * dbusbind.c (Fdbus_register_signal): Add match rule to
9753 Vdbus_registered_objects_table. (Bug#9581)
9754 (Fdbus_register_method, Vdbus_registered_objects_table):
9757 2011-09-24 Jim Meyering <meyering@redhat.com>
9759 do not ignore write error for any output size
9760 The previous change was incomplete.
9761 While it makes emacs --batch detect the vast majority of stdout
9762 write failures, errors were still ignored whenever the output size is
9763 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
9764 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
9765 && echo FAIL: ignored write error
9766 FAIL: ignored write error
9767 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
9768 && echo FAIL: ignored write error
9769 FAIL: ignored write error
9770 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
9772 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
9774 * emacs.c (Fkill_emacs): In noninteractive mode exit
9775 non-successfully if a write error occurred on stdout. (Bug#9574)
9777 2011-09-21 Eli Zaretskii <eliz@gnu.org>
9779 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
9782 * dispextern.h (struct it): Update the comment documenting what
9785 2011-09-20 Eli Zaretskii <eliz@gnu.org>
9787 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
9788 a display string, extend search for cursor position to end of row.
9789 (find_row_edges): If the row ends in a newline from a display
9790 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
9791 Handle the case of a display string with multiple newlines.
9792 (Fcurrent_bidi_paragraph_direction): Fix search for previous
9793 non-empty line. Fixes confusing cursor motion with arrow keys at
9794 the beginning of a line that starts with whitespace.

9803 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
9806 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9808 * xdisp.c (display_line): Record maximum and minimum buffer
9809 positions even if no glyphs were produced (e.g., by a zero-width
9810 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
9811 buffer positions that will be removed from the glyph row because
9813 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
9814 column is beyond frame width: don't subtract 1 "pixel" when
9815 computing width of the stretch.
9816 (reseat_at_next_visible_line_start): Undo the change made on
9817 2011-09-17 that saved paragraph information and restored it after
9818 the call to `reseat'. (Bug#9545)
9820 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9822 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
9823 and turn window cursor on if cleared (Bug#9415).

9836 Fix minor problem found by static checking.
9837 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
9838 initialized, to pacify gcc -Wuninitialized.
9840 * fileio.c: Report proper errno when syscall falls.
9841 (Finsert_file_contents): Save and restore errno,
9842 so that report_file_error outputs the correct diagnostic.
9843 (Fwrite_region) [CLASH_DETECTION]: Likewise.
9845 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9847 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
9849 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9851 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
9852 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
9854 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9856 * xdisp.c (reseat_at_next_visible_line_start): Keep information
9857 about the current paragraph and restore it after the call to reseat.
9859 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
9860 (bidi_find_paragraph_start): Search back for paragraph beginning
9861 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
9862 (bidi_move_to_visually_next): Only trigger paragraph-related
9863 computations when the last character is a newline or at EOB, not
9864 just any NEUTRAL_B. (Bug#9470)
9866 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
9867 truncated lines if point is covered by a display string. (Bug#9524)
9869 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
9871 * xselect.c: Relax test for outgoing X longs (Bug#9498).
9872 (cons_to_x_long): New function.
9873 (lisp_data_to_selection_data): Use it. Correct the test for
9874 short-versus-long data; it was negated. Break out of vector
9875 loop, for efficiency, when a long datum is discovered.
9877 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
9879 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
9881 2011-09-16 Eli Zaretskii <eliz@gnu.org>
9883 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
9884 GCC PR/17406) by declaring this function with external scope.
9886 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>

9907 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
9908 This occurs when processing a multibyte format.
9909 Problem reported by Wolfgang Jenker.
9911 2011-09-15 Johan Bockgård <bojohan@gnu.org>
9913 * xdisp.c (try_cursor_movement): Only check for exact match if
9914 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
9916 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9918 Remove unused external symbols.
9919 * dispextern.h (calc_pixel_width_or_height): Remove decl.
9920 * xdisp.c (calc_pixel_width_or_height): Now static.
9921 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
9922 * indent.c (check_display_width):
9923 * w32term.c: Fix comment to match code.
9924 * xterm.c, xterm.h (x_catching_errors): Remove.
9926 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9928 * xselect.c: Use signed conversions more consistently (Bug#9498).
9929 (selection_data_to_lisp_data): Assume incoming selection data are
9930 signed integers, not unsigned. This is to be consistent with
9931 outgoing selection data, which was modified to use signed integers
9932 in as part of the fix to Bug#9196 in response to Jan D.'s comment
9933 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
9934 expects long, not unsigned long.
9936 2011-09-14 Eli Zaretskii <eliz@gnu.org>
9938 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
9939 computation of loop end. Reported by Johan Bockgård
9942 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
9944 * frame.c (Fother_visible_frames_p): Function deleted.
9946 2011-09-12 Eli Zaretskii <eliz@gnu.org>
9948 * indent.c (compute_motion): Process display vector front to back
9949 rather than the other way around. (Bug#2496)
9951 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
9953 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
9955 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
9957 * minibuf.c (Fread_from_minibuffer): Doc fix.
9959 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9961 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
9962 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
9964 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
9966 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
9967 value for non-existent files.
9969 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9971 * fileio.c (Finsert_file_contents): If the file cannot be opened,
9972 set its "size" to -1. This will set the modtime_size field of
9973 the corresponding buffer to -1, which is what
9974 verify-visited-file-modtime expects for files that do not exist.
9977 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
9979 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
9981 * lisp.h: ... from here. push_key_description is no longer
9982 defined in keyboard.c, so its declaration should not be in
9983 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
9984 logically belongs with push_key_description.
9986 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
9988 * buffer.h: Include <sys/types.h> instead of <time.h>.
9989 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
9990 Problem reported by Herbert J. Skuhra.
9992 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
9994 * xml.c (parse_region): Make the parsing work for
9995 non-comment-starting XML files again (bug#9144).
9997 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
9999 * image.c (gif_load): Fix calculation of bottom and right corner.
10002 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10004 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10005 redisplay in small windows.
10007 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10009 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10011 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10013 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10014 Operate on live windows only.
10016 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10018 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10020 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10022 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10023 only under bidi iteration.
10025 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10027 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10029 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10031 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10032 Without this fix, the command to link temacs failed due to an
10033 undefined symbol __builtin_isnan. This is because
10034 /usr/include/iso/math_c99.h #defines isnan(x) to
10035 __builtin_isnan(x), but the bundled gcc, which identifies itself
10036 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10038 * floatfns.c (isnan): #undef, and then #define to a clone of
10040 (Fisnan): Always define, since it's always available now.
10041 (syms_of_floatfns): Always define isnan at the Lisp level.
10043 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10045 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10047 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10049 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10050 The previous code assumed that file offsets (off_t values) fit in
10051 EMACS_INT variables, which is not true on typical 32-bit hosts.
10052 The code messed up by falsely reporting buffer overflow in cases
10053 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10054 when "big" contains more than 2**29 bytes, even though this
10055 inserts just one byte and does not overflow the buffer.
10056 (Finsert_file_contents): Store file offsets as off_t
10057 values, not as EMACS_INT values. Check for overflow when
10058 converting between EMACS_INT and off_t. When checking for
10059 buffer overflow or for overlap, take the offsets into account.
10060 Don't use EMACS_INT for small values where int suffices.
10061 When checking for overlap, fix a typo: ZV was used where
10062 ZV_BYTE was intended.
10063 (Fwrite_region): Don't assume off_t fits into 'long'.
10064 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10066 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10068 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10070 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10072 sprintf-related integer and memory overflow issues (Bug#9412).
10074 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10075 (esprintf, exprintf, evxprintf): New functions.
10076 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10077 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10078 (modify_event_symbol): Do not assume that the length of
10079 name_alist_or_stem is safe to alloca and fits in int.
10080 (Fexecute_extended_command): Likewise for function name and binding.
10081 (Frecursion_depth): Wrap around reliably on integer overflow.
10082 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10083 since some callers pass EMACS_INT values.
10084 (Fsingle_key_description): Don't crash if symbol name contains more
10085 than MAX_ALLOCA bytes.
10086 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10087 (get_minibuffer): Arg is now EMACS_INT, not int.
10088 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10089 (esprintf, exprintf, evxprintf): New decls.
10090 * window.h (command_loop_level, minibuf_level): Reflect API changes.
10092 * dbusbind.c (signature_cat): New function.
10093 (xd_signature, Fdbus_register_signal):
10094 Do not overrun buffer; instead, report string overflow.
10096 * dispnew.c (add_window_display_history): Don't overrun buffer.
10097 Truncate instead; this is OK since it's just a log.
10099 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10100 even if the time zone offset is outlandishly large.
10101 Don't mishandle offset == INT_MIN.
10103 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10104 when creating daemon; the previous buffer-overflow check was incorrect.
10106 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10107 which has the guts of the old verror function.
10109 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10110 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10112 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10113 (font_unparse_xlfd): Don't blindly alloca long strings.
10114 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10115 fits in int, when using sprintf. Use single snprintf to count
10116 length of string rather than counting it via multiple sprintfs;
10117 that's simpler and more reliable.
10118 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10119 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10120 sprintf, in case result does not fit in int.
10122 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10123 (fontset_from_font): Print it.
10125 * frame.c (tty_frame_count): Now printmax_t, not int.
10126 (make_terminal_frame, set_term_frame_name): Print it.
10127 (x_report_frame_params): In X, window IDs are unsigned long,
10128 not signed long, so print them as unsigned.
10129 (validate_x_resource_name): Check for implausibly long names,
10130 and don't assume name length fits in 'int'.
10131 (x_get_resource_string): Don't blindly alloca invocation name;
10132 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10135 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10136 (xg_check_special_colors, xg_set_geometry):
10137 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10139 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10140 Use esprintf, not sprintf, in case result does not fit in int.
10142 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10143 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10144 it as a large positive number.
10145 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10146 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10148 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10149 in case result does not fit in int.
10151 * print.c (float_to_string): Detect width overflow more reliably.
10152 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10153 buffer overrun. Don't assume list length fits in 'int'. Treat
10154 print length of 0 as 0, not as infinity; to be consistent with other
10155 uses of print length in this function. Don't overflow print length
10156 index. Don't assume hash table size fits in 'long', or that
10157 vectorlike size fits in 'unsigned long'.
10159 * process.c (make_process): Use printmax_t, not int, to format
10160 process-name gensyms.
10162 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10164 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10165 to avoid potential buffer overrun.
10167 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10168 if X resource line is longer than 512 bytes.
10170 * xfns.c (x_window): Make sprintf buffer a bit bigger
10171 to avoid potential buffer overrun.
10173 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10175 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10177 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10179 Integer overflow fixes for scrolling, etc.
10180 Without these, Emacs silently mishandles large integers sometimes.
10181 For example, "C-u 4294967297 M-x recenter" was treated as if
10182 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10184 * xdisp.c (try_window_id): Check Emacs fixnum range before
10185 converting to 'int'.
10187 * window.c (window_scroll_line_based, Frecenter):
10188 Check that an Emacs fixnum is in range before assigning it to 'int'.
10189 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10190 values converted from Emacs fixnums.
10191 (Frecenter): Don't wrap around a line count if it is out of 'int'
10192 range; instead, treat it as an extreme value.
10193 (Fset_window_configuration, compare_window_configurations):
10194 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10196 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10197 that can exceed INT_MAX. Check that EMACS_INT value is in range
10198 before assigning it to the (possibly-narrower) index.
10199 (match_limit): Don't assume that a fixnum can fit in 'int'.
10201 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10204 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10205 (Fvertical_motion): Don't wrap around LINES values that don't fit
10206 in 'int'. Instead, treat them as extreme values. This is good
10207 enough for windows, which can't have more than INT_MAX lines anyway.
10209 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10211 * Require libxml/parser.h to avoid compilation warning.
10213 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10215 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10216 since this reportedly can destroy thread storage.
10218 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10220 * syntax.c (find_defun_start): Update all cache variables if
10221 exiting early (Bug#9401).
10223 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10225 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10227 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10228 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10229 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10231 * term.c (tty_append_glyph): New function.
10232 (produce_stretch_glyph): Static function and its prototype deleted.
10234 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10237 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10239 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10240 when checking :margin (Bug#9390).
10241 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10242 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10243 so that the name doesn't mislead. All uses changed.
10245 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10247 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
10250 2011-08-27 Eli Zaretskii <eliz@gnu.org>
10252 * xdisp.c (move_it_to): Don't bail out early when reaching
10253 position beyond to_charpos, if we are scanning backwards.
10254 (move_it_vertically_backward): When DY == 0, make sure we get to
10255 the first character in the line after the newline.
10257 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10259 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10260 (ccl_driver): Do not generate an out-of-range pointer.
10261 (Fccl_execute_on_string): Remove unnecessary check for
10262 integer overflow, noted by Stefan Monnier in
10263 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10264 Remove a FIXME that didn't need fixing.
10265 Simplify the newly-introduced buffer reallocation code.
10267 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10269 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10271 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10273 Integer and memory overflow issues (Bug#9196).
10275 * doc.c (get_doc_string): Rework so that
10276 get_doc_string_buffer_size is the actual buffer size, rather than
10277 being 1 less than the actual buffer size; this makes xpalloc more
10280 * image.c (x_allocate_bitmap_record, cache_image):
10281 * xselect.c (Fx_register_dnd_atom):
10282 Simplify previous changes by using xpalloc.
10284 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10285 since either will do and ptrdiff_t is convenient with xpalloc.
10287 * charset.c (charset_table_size)
10288 (struct charset_sort_data.priority): Now ptrdiff_t.
10289 (charset_compare): Don't overflow if priorities differ greatly.
10290 (Fsort_charsets): Don't assume list length fits in int.
10291 Check for size-calculation overflow when allocating sort data.
10292 (syms_of_charset): Allocate an initial charset table that is
10293 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10295 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10297 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10298 The actual value is always <= INT_MAX, and leaving it unsigned made
10299 overflow checking harder.
10301 * dispextern.h (struct glyph_matrix.rows_allocated)
10302 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10303 with xpalloc. The values are still always <= INT_MAX.
10305 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10307 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10308 (SAFE_NALLOCA): New macro.
10310 * region-cache.c (struct boundary.pos, find_cache_boundary)
10311 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10312 (set_cache_region, invalidate_region_cache)
10313 (revalidate_region_cache, know_region_cache, region_cache_forward)
10314 (region_cache_backward, pp_cache):
10315 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10316 so that ptrdiff_t * can be passed to xpalloc.
10317 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
10318 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
10319 (pp_cache): Don't assume cache_len fits in int.
10320 * region-cache.h: Adjust extern decls to match.
10322 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
10323 EMACS_INT, since either will do, for xpalloc.
10325 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
10326 (xnmalloc, xnrealloc, xpalloc): New functions.
10328 * bidi.c (bidi_shelve_header_size): New constant.
10329 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
10330 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
10332 * bidi.c (bidi_cache_shrink):
10333 * buffer.c (overlays_at, overlays_in, record_overlay_string)
10335 Don't update size of array until after memory allocation succeeds,
10336 because xmalloc/xrealloc may not return.
10337 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10338 now that we have proper integer overflow checking.
10339 (record_overlay_string, overlay_strings): Catch overflows when
10340 calculating size of overlay_str_buf.
10342 * callproc.c (Fcall_process): Check for size overflow when
10343 calculating size of args2.
10344 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
10345 Normally we prefer signed values, but sticking with ptrdiff_t would
10346 require adding more-complicated checks.
10348 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10349 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
10350 Redo buffer-overflow calculations to avoid integer overflow.
10351 Add a FIXME comment where memory seems to be over-allocated.
10353 * character.c (Fstring): Check for size-calculation overflow.
10355 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
10356 unnecessary integer overflow. Check for size overflow.
10357 (encode_coding_object): Don't update size until xmalloc succeeds.
10359 * composite.c (get_composition_id): Check for overflow in glyph
10360 length calculations.
10362 Integer and memory overflow fixes for display code.
10363 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
10364 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
10365 (scrolling_window): Check for overflow in size calculations.
10366 (line_draw_cost, realloc_glyph_pool, add_row_entry):
10367 Don't assume glyph table len fits in int.
10368 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
10369 (row_table_size): Now ptrdiff_t, not int.
10370 (scrolling_window): Avoid overflow in size calculations.
10371 Don't update size until allocation succeeds.

10389 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10391 * emacs.c (main): Do not reallocate argv, since there is a null at
10392 the end that can be overwritten, and this way there's no need to
10393 worry about size-calculation overflow.
10394 (sort_args): Check for size-calculation overflow.

10416 Check for size-calculation overflow.
10417 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10418 do, as we prefer signed integers.

10511 (Fx_change_window_property): Use ptrdiff_t, not int, to count
10512 sizes, since they can exceed INT_MAX in size. Check for size

10523 (X_LONG_MIN): New macros.
10524 Use them to make the following changes clearer.
10525 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
10526 This change doesn't affect the value now, but it may help remind
10527 future maintainers not to raise the value too much later.
10528 (SELECTION_QUANTUM): Remove, replacing with ...
10529 (selection_quantum): ... new function, which avoids overflow.
10531 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10532 assumption that selection length fits in 'int'.

10549 Don't store size until memory allocation succeeds.
10550 (x_get_window_property): Plug memory leak on memory exhaustion.
10551 Don't double-block input; malloc is safe here. Don't assume 2**34
10552 - 4 fits in unsigned long. Add an xassert to check
10553 XGetWindowProperty overflow. Be more careful about overflow
10554 calculations, and distinguish size from memory overflow better.
10555 (receive_incremental_selection): When tracing, don't assume
10556 unsigned int is less than INT_MAX.
10557 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

10561 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10562 result parameters unless successful. Rely on cons_to_unsigned
10563 to report problems with elements; the old code wasn't right anyway.

10598 * lisp.h (hash_lookup, hash_put):
10599 * minibuf.c (Ftest_completion):
10600 Use ptrdiff_t for hash table indexes, not int (which is too
10601 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
10602 32-bit --with-wide-int hosts).
10604 * charset.c (Fdefine_charset_internal): Check for integer overflow.
10605 Add a FIXME comment about memory leaks.

10636 exceed limits imposed by XClientMessageEvent, as well as the usual
10637 ptrdiff_t and size_t limits.

10640 (make_lispy_movement): Use same integer type in forward decl
10641 that is used in the definition.
10642 (read_key_sequence, keyremap_step):
10643 Change bufsize argument back to int, undoing my 2011-03-30 change.
10644 We prefer signed types, and int is wide enough here.
10645 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
10646 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
10647 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
10648 length, not size_t. Use ptrdiff_t for index, not int.
10649 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
10650 possibility of integer overflow.

10678 Prefer int to unsigned where either will do.
10679 (tiff_handler): New function, combining the cores of the
10680 old tiff_error_handler and tiff_warning_handler.

10682 stack buffer overflows. It uses only the features of vsnprintf
10683 that are common to both POSIX and native Microsoft.
10684 (tiff_error_handler, tiff_warning_handler): Use it.
10685 (tiff_load, gif_load, imagemagick_load_image):
10686 Don't assume :index value fits in 'int'.
10687 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

10689 the integer types that MagickCropImage accepts. Don't assume
10690 Vimagemagick_render_type has a nonnegative value. Don't assume
10691 size_t fits in 'long'.
10692 (gs_load): Use printmax_t to print the widest integers possible.

10729 buffers, return left-to-right.
10730 (set_cursor_from_row): Consider candidate row a win if its glyph

10732 positioning on the newline at EOL of R2L text within L2R
10733 paragraph, and vice versa.
10734 (try_cursor_movement): Check continued rows, in addition to
10735 continuation rows. Fixes unwarranted scroll when point enters a
10736 continued line of R2L text within an L2R paragraph, or vice versa.
10737 (cursor_row_p): Consider the case of point being equal to
10738 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
10739 from the end of a short line to the beginning of a continued line
10740 of R2L text within L2R paragraph.

10767 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
10768 instead of CHAR_TO_BYTE. Fixes a crash when a completion
10769 candidate is selected by the mouse, and that candidate has a
10770 composed character under the mouse.
10772 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
10773 coordinates reported by pos-visible-in-window-p for a composed

10783 consider it a hit if to_charpos is anywhere in the range of the
10784 composed buffer positions.
10786 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
10788 * image.c (gif_load): Don't assume that each subimage has the same
10789 dimensions as the base image. Handle disposal method that is
10790 "undefined" by the gif spec (Bug#9335).
10792 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
10794 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

10804 a composition, take its buffer position from IT->cmp_it.charpos.
10805 Fixes cursor positioning at the beginning of a line that begins
10806 with a composed character.
10808 2011-08-18 Eli Zaretskii <eliz@gnu.org>
10810 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
10811 character bidirectional type, use STRONG_L instead. Fixes crashes
10812 in a buffer produced by `describe-categories'.
10814 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
10815 members before the level stack, so they would be saved and
10816 restored when copying iterator state. Fixes incorrect reordering
10817 around TABs covered by display properties.
10819 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
10821 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
10823 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
10825 * eval.c (internal_condition_case, internal_condition_case_1)
10826 (internal_condition_case_2, internal_condition_case_n):
10827 Remove unnecessary aborts (Bug#9081).
10829 2011-08-17 Eli Zaretskii <eliz@gnu.org>
10831 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
10832 has no `load' handler, try opening the file locally. (Bug#9311)
10834 2011-08-16 Ken Brown <kbrown@cornell.edu>
10836 * gmalloc.c: Expand comment.
10838 2011-08-16 Eli Zaretskii <eliz@gnu.org>
10840 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
10841 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
10843 2011-08-16 Ken Brown <kbrown@cornell.edu>
10845 Fix memory allocation problems in Cygwin build (Bug#9273).
10847 * unexcw.c ( __malloc_initialized): Declare external variable.

10852 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
10854 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
10855 in the static heap.
10856 [CYGWIN] (special_realloc): New function.
10857 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
10858 requests to realloc storage in the static heap.

10869 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
10871 * dispextern.h: Fix a typo in the comment to bidi_type_t.
10873 * chartab.c: Improve commentary for the uniprop_table API.
10875 * bidi.c (bidi_paragraph_init): Support zero value of
10876 bidi_ignore_explicit_marks_for_paragraph_level.
10877 (bidi_initialize): Use uniprop_table instead of including
10878 biditype.h and bidimirror.h.
10880 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
10881 coordinates of the iterator when restoring from ppos_it.
10884 2011-08-14 Kenichi Handa <handa@m17n.org>
10886 * process.c (create_process): Call setup_process_coding_systems
10887 after the pid of the process is set to -1 (Bug#8162).
10889 2011-08-14 Eli Zaretskii <eliz@gnu.org>
10891 * xdisp.c (move_it_in_display_line_to): Don't invoke
10892 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
10893 ppos_it. Fixes vertical cursor motion when line beginning is
10894 covered by an image. (Bug#9296)
10896 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
10898 * nsterm.h (ns_run_ascript): Declare.
10899 (NSAPP_DATA2_RUNASSCRIPT): Define.
10901 * nsfns.m (as_script, as_result, as_status): New static variables.
10902 (ns_run_ascript): New function.
10903 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
10904 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
10905 the event loop. Get status from as_status (Bug#7276).
10907 * nsterm.m (sendEvent): If event is NSApplicationDefined and
10908 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
10909 the event loop (Bug#7276).
10911 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
10913 * gnutls.c (QCgnutls_bootprop_priority)
10914 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
10915 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
10916 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
10917 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
10918 (QCgnutls_bootprop_verify_hostname_error)
10919 (QCgnutls_bootprop_callbacks_verify): Rename from
10920 Qgnutls_bootprop_..., all uses changed.
10922 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
10925 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
10927 * xfaces.c (Qframe_set_background_mode): Now static.

10932 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
10934 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
10935 (Fnetwork_interface_list): Allocate in increments of bytes instead
10936 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
10937 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
10939 (struct ifflag_def): notrailers is smart on OSX.
10940 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
10941 Get hardware address with getifaddrs if available.
10943 2011-08-12 Eli Zaretskii <eliz@gnu.org>
10945 * xdisp.c (iterate_out_of_display_property): xassert that
10946 IT->position is set to within IT->object's boundaries. Break from
10947 the loop as soon as EOB is reached; avoids infloops in redisplay
10948 when IT->position is set up wrongly due to some bug.
10949 Set IT->current to match the bidi iterator unconditionally.
10950 (push_display_prop): Allow GET_FROM_STRING as IT->method on
10951 entry. Force push_it to save on the stack the current
10952 buffer/string position, to be restored by pop_it. Fix flags in
10953 the iterator structure wrt the object coming from a display
10954 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
10955 properties. (Bug#9284)
10957 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
10959 * fontset.c (fontset_get_font_group): Add proper type checks.
10962 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

10965 and LC_VERSION_MIN_MACOSX.
10966 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
10967 (dump_it) [LC_FUNCTION_STARTS]: Use it.
10969 2011-08-08 Eli Zaretskii <eliz@gnu.org>
10971 * xdisp.c (forward_to_next_line_start): Allow to use the
10972 no-display-properties-and-no-overlays under bidi display.
10973 Set disp_pos in the bidi iterator to avoid searches for display
10974 properties and overlays.
10976 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
10978 * editfns.c (Fset_time_zone_rule): Document relationship with the

10982 the font entity extracted from the cache (Bug#8109).
10984 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
10986 * composite.c (autocmp_chars): Don't reset point. That is done by
10987 restore_point_unwind (Bug#5984).
10989 2011-08-07 Juri Linkov <juri@jurta.org>
10991 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
10992 to show the arg `TIME' instead of `TIMEVAL'.
10994 2011-08-06 Eli Zaretskii <eliz@gnu.org>
10996 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
10997 display property strides EOL and includes a newline, as in
10998 longlines-mode. (Bug#9254)
10999 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
11000 word-wrap under bidirectional display. (Bug#9224)
11002 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
11003 is non-zero, even if the data buffer is NULL. Fixes a crash in
11004 vertical-motion with longlines-mode. (Bug#9254)
11006 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11008 * bidi.c <bidi_cache_total_alloc>: Now static.
11009 (bidi_initialize): Initialize bidi_cache_total_alloc.
11011 * xdisp.c (display_line): Release buffer allocated for shelved bidi
11014 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
11015 amount allocated this far in `bidi_cache_total_alloc'.
11016 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
11017 non-zero, only free the data buffer without restoring the cache
11018 contents. All callers changed.
11020 * dispextern.h (bidi_unshelve_cache): Update prototype.
11022 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
11023 (move_it_in_display_line, move_it_to)
11024 (move_it_vertically_backward, move_it_by_lines): Replace the call
11025 to xfree to an equivalent call to bidi_unshelve_cache.
11026 (move_it_in_display_line_to): Fix logic of returning
11027 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
11029 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11031 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
11032 came from a string character with a `cursor' property. (Bug#9229)
11034 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11036 * Makefile.in (LIB_PTHREAD): New variable.
11037 (LIBES): Add LIB_PTHREAD (Bug#9216).
11039 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
11040 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
11042 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
11044 * regex.c (re_iswctype): Remove some redundant boolean conversions.
11046 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11048 * xterm.c (x_find_topmost_parent): New function.
11049 (x_set_frame_alpha): Find topmost parent window with
11050 x_find_topmost_parent and set the property there also (bug#9181).
11051 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
11053 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
11055 * callproc.c (Fcall_process): Avoid vfork clobbering
11056 the local vars buffer, coding_systems, current_dir.
11058 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
11060 * keymap.c (Fmake_composed_keymap): Move to subr.el.
11062 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
11064 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
11065 so that it is not optimized away.
11067 * xdisp.c (compute_display_string_pos): Remove unused local.
11069 2011-08-02 Eli Zaretskii <eliz@gnu.org>
11071 Fix slow cursor motion and scrolling in large buffers with
11072 selective display, like Org Mode buffers. (Bug#9218)
11074 * dispextern.h (struct bidi_it): New member disp_prop_p.
11076 * xdisp.c: Remove one-slot cache of display string positions.
11077 (compute_display_string_pos): Accept an additional argument
11078 DISP_PROP_P; callers changed. Scan at most 5K characters forward
11079 for a display string or property. If found, set DISP_PROP_P
11082 * bidi.c (bidi_fetch_char): Accept an additional argument
11083 DISP_PROP_P, and pass it to compute_display_string_pos.
11084 Only handle text covered by a display string if DISP_PROP_P is returned
11085 non-zero. All callers of bidi_fetch_char changed.
11087 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
11089 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
11091 2010-12-03 Don March <don@ohspite.net>
11093 * keymap.c (Fdefine_key): Fix non-prefix key error message when
11094 last character M-[char] is translated to ESC [char] (bug#7541).
11096 2011-08-02 Kenichi Handa <handa@m17n.org>
11098 * lisp.h (uniprop_table): Extern it.
11100 * chartab.c (uniprop_table): Make it non-static.
11102 2011-08-01 Eli Zaretskii <eliz@gnu.org>
11104 * xdisp.c (forward_to_next_line_start): Accept additional argument
11105 BIDI_IT_PREV, and store into it the state of the bidi iterator had
11107 (reseat_at_next_visible_line_start): Use the bidi iterator state
11108 returned by forward_to_next_line_start to restore the state of
11109 it->bidi_it after backing up to previous newline. (Bug#9212)
11111 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
11113 * regex.c (re_comp): Protoize.
11114 (re_exec): Fix return type.
11115 (regexec): Fix type of `ret'. (Bug#9203)
11117 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11119 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
11120 This is needed if max-image-size is a floating-point number.
11122 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11124 * print.c (print_object): Print empty symbol as ##.
11126 * lread.c (read1): Read ## as empty symbol.
11128 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11130 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
11131 setting frame foreground color (Bug#9175).
11132 (x_set_background_color): Likewise.
11134 * nsmenu.m (-setText): Size tooltip dimensions precisely to
11135 contents (Bug#9176).
11136 (EmacsTooltip -init): Remove bezels and add shadows to
11139 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
11140 or scroll bar (Bug#8470).
11142 * nsfont.m (nsfont_open): Remove assignment to voffset and
11143 unnecessary vars hshink, expand, hd, full_height, min_height.
11144 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
11146 * nsterm.h (nsfont_info): Remove voffset field.
11148 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11150 Implement strike-through and overline on NextStep (Bug#8863).
11152 * nsfont.m (nsfont_open): Use underline position provided by font,
11153 instead of hard-coded value of 2.
11154 (nsfont_draw): Call ns_draw_text_decoration instead.
11156 * nsterm.h: Add declaration for ns_draw_text_decoration.
11158 * nsterm.m (ns_draw_text_decoration): New function for drawing
11159 underline, overline, and strike-through.
11160 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
11161 ns_draw_text_decoration. Change treatment of cursor drawing to
11162 accommodate underlining, etc.
11164 2011-07-28 Eli Zaretskii <eliz@gnu.org>
11166 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
11169 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11171 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11172 Without this fix, if a signal arrives just after memory fills up,
11173 'malloc' might be invoked reentrantly.
11175 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11176 In other words, assume that every image size is allowed, on non-X
11177 hosts. This assumption is probably wrong, but it lets Emacs compile.
11179 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11181 * regex.c (re_iswctype): Convert return values to boolean.
11183 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
11185 * xdisp.c (compute_display_string_pos): Don't use cached display
11186 string position if the buffer had its restriction changed.
11189 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11191 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11193 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11195 Integer signedness and overflow and related fixes. (Bug#9079)
11197 * bidi.c: Integer size and overflow fixes.
11198 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
11199 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
11200 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11201 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11202 (bidi_find_other_level_edge):
11203 Use ptrdiff_t instead of EMACS_INT where either will do.
11204 This works better on 32-bit hosts configured --with-wide-int.
11205 (bidi_cache_ensure_space): Check for size-calculation overflow.
11206 Use % rather than repeated addition, for better worst-case speed.
11207 Don't set bidi_cache_size until after xrealloc returns, because it
11209 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11210 (bidi_cache_ensure_space): Also check that the bidi cache size
11211 does not exceed that of the largest Lisp string or buffer. See Eli
11212 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11214 * alloc.c (__malloc_size_t): Remove.
11215 All uses replaced by size_t. See Andreas Schwab's note
11216 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11218 * image.c: Improve checking for integer overflow.
11219 (check_image_size): Assume that f is nonnull, since
11220 it is always nonnull in practice. This is one less thing to
11221 worry about when checking for integer overflow later.
11222 (x_check_image_size): New function, which checks for integer
11223 overflow issues inside X.
11224 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11225 This removes the need for a memory_full check.
11226 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11227 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11228 (xbm_read_bitmap_data): Change locals back to 'int', since
11229 their values must fit in 'int'.
11230 (xpm_load_image, png_load, tiff_load):
11231 Invoke x_create_x_image_and_pixmap earlier,
11232 to avoid much needless work if the image is too large.
11233 (tiff_load): Treat overly large images as if
11234 x_create_x_image_and_pixmap failed, not as malloc failures.
11235 (gs_load): Use x_check_image_size.
11237 * gtkutil.c: Omit integer casts.
11238 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11239 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11241 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11243 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11244 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11245 would wrongly return t on a 64-bit host.
11247 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11248 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11249 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11250 and therefore cause GCC to emit a bogus diagnostic in some cases.
11252 * image.c: Integer signedness and overflow and related fixes.
11253 This is not an exhaustive set of fixes, but it's time to
11254 record what I've got.
11255 (lookup_pixel_color, check_image_size): Remove redundant decls.
11256 (check_image_size): Don't assume that arbitrary EMACS_INT values
11257 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11258 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11259 (tiff_load, imagemagick_load_image):
11260 Check for overflow in size calculations.
11261 (x_create_x_image_and_pixmap): Remove unnecessary test for
11262 xmalloc returning NULL; that can't happen.
11263 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11264 (xpm_color_bucket): Use better integer hashing function.
11265 (xpm_cache_color): Don't possibly over-allocate memory.
11266 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11267 (gif_memory_source):
11268 Use ptrdiff_t, not int or size_t, to record sizes.
11269 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11270 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11271 either works, as we prefer signed integers.
11272 (tiff_read_from_memory, tiff_write_from_memory):
11273 Return tsize_t, not size_t, since that's what the TIFF API wants.
11274 (tiff_read_from_memory): Don't fail simply because the read would
11275 go past EOF; instead, return a short read.
11276 (tiff_load): Omit no-longer-needed casts.
11277 (Fimagemagick_types): Don't assume size fits into 'int'.
11279 Improve hashing quality when configured --with-wide-int.
11280 * fns.c (hash_string): New function, taken from sxhash_string.
11281 Do not discard information about ASCII character case; this
11282 discarding is no longer needed.
11283 (sxhash-string): Use it. Change sig to match it. Caller changed.
11284 * lisp.h: Declare it.
11285 * lread.c (hash_string): Remove, since we now use fns.c's version.
11286 The fns.c version returns a wider integer if --with-wide-int is
11287 specified, so this should help the quality of the hashing a bit.
11289 * emacs.c: Integer overflow minor fix.
11290 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11291 Define only if GNU_LINUX.
11292 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11294 * dispnew.c: Integer signedness and overflow fixes.
11295 Remove unnecessary forward decls, that were a maintenance hassle.
11296 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11298 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11299 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11300 (prepare_desired_row, line_draw_cost):
11301 Use int, not unsigned, where either works.
11302 (save_current_matrix, restore_current_matrix):
11303 Use ptrdiff_t, not size_t, where either works.
11304 (init_display): Check for overflow more accurately, and without
11305 relying on undefined behavior.
11307 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11308 Remove, replacing with the new symbols in lisp.h. All uses changed.
11309 * fileio.c (make_temp_name):
11310 * filelock.c (lock_file_1, lock_file):
11311 * xdisp.c (message_dolog):
11312 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11313 Use pMd etc. instead.
11314 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11315 replacing the pWIDE etc. symbols removed from editfns.c.
11317 * keyboard.h (num_input_events): Now uintmax_t.
11318 This is (very slightly) less likely to mess up due to wraparound.
11321 * buffer.c: Integer signedness fixes.
11322 (alloc_buffer_text, enlarge_buffer_text):
11323 Use ptrdiff_t rather than size_t when either will do, as we prefer
11326 * alloc.c: Integer signedness and overflow fixes.
11327 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11328 (__malloc_size_t): Default to size_t, not to int.
11329 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11330 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11331 Prefer ptrdiff_t to size_t when either would do, as we prefer
11333 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11334 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11335 Now const. Initialize with values that are in range even if char
11337 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11338 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11339 These functions do the right thing with sizes > 2**32.
11340 (check_depth): Now ptrdiff_t, not int.
11341 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11342 Adjust to new way of storing sizes. Check for size overflow bugs
11344 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11345 slightly wrong anyway, as it missed one instance of
11346 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11347 (refill_memory_reserve): Omit needless cast to size_t.
11348 (mark_object_loop_halt): Mark as externally visible.
11350 * xselect.c: Integer signedness and overflow fixes.
11351 (Fx_register_dnd_atom, x_handle_dnd_message):
11352 Use ptrdiff_t, not size_t, since we prefer signed.
11353 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11354 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11355 x_dnd_atoms_size and x_dnd_atoms_length.
11357 * doprnt.c: Prefer signed to unsigned when either works.
11359 * doprnt.c (doprnt):
11361 * xdisp.c (vmessage):
11362 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11363 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11364 prefer signed arithmetic to avoid comparison confusion.
11365 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11366 but is a bit tricky.
11368 Assume freestanding C89 headers, string.h, stdlib.h.
11369 * data.c, doprnt.c, floatfns.c, print.c:
11370 Include float.h unconditionally.
11371 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11372 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11373 * regex.c: Likewise for stddef.h, string.h.
11374 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11375 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11376 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11377 (STDC_HEADERS): Remove obsolete defines.
11378 * sysdep.c: Include limits.h unconditionally.
11380 Assume support for memcmp, memcpy, memmove, memset.
11381 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11382 * regex.c (memcmp, memcpy):
11383 Remove; we assume C89 now.
11385 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11386 (__malloc_safe_bcopy): Remove; no longer needed.
11388 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11389 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11390 well either way, and we prefer signed to unsigned.
11392 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11394 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11395 closes the connection while we're reading (bug#9182).
11397 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11399 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11400 are specified (Bug#9168).
11402 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11404 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11405 Found by GCC static checking and --with-wide-int on a 32-bit host.
11407 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11409 * xdisp.c (compute_display_string_pos): Fix logic of caching
11410 previous display string position. Initialize cached_prev_pos to
11411 -1. Fixes slow-down at the beginning of a buffer.
11413 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11415 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11416 for attrs[LFACE_FONTSET_INDEX].
11418 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11420 * xml.c (parse_region): Remove unused local
11421 that was recently introduced.
11423 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11425 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11426 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11428 * xdisp.c (move_it_in_display_line_to): Record the best matching
11429 position for TO_CHARPOS while scanning the line, and restore it on
11430 exit if none of the characters scanned was an exact match.
11431 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11432 when exact match is impossible due to invisible text, and the
11433 lines are truncated.
11435 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11437 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11440 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11442 Fix a significant slow-down of cursor motion with C-n, C-p,
11443 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11444 auto-repeat under bidi redisplay in fontified buffers.
11445 * xdisp.c (compute_stop_pos_backwards): New function.
11446 (next_element_from_buffer): Call compute_stop_pos_backwards to
11447 find a suitable prev_stop when we find ourselves before
11449 (reseat): Don't look for prev_stop, as that could mean a very long
11451 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11452 <cached_disp_overlay_modiff>: Cache for last found display string
11454 (compute_display_string_pos): Return the cached position if asked
11455 about the same buffer in the same area of character positions, and
11456 the buffer wasn't changed since the time the display string
11457 position was cached.
11459 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11461 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11462 is an integer, which is important for empty lines. (Bug#9149)
11464 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11466 * frame.c (Fmodify_frame_parameters): In tty case, update the
11467 default face if necessary (Bug#4238).
11469 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11471 * editfns.c (Fstring_to_char): No need to explain what a character
11472 is in the docstring (Bug#6576).
11474 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11476 * xml.c (parse_region): Make sure we always return a tree.
11478 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11480 * xml.c (parse_region): If a document contains only comments,
11483 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11485 * xml.c (make_dom): Return comments, too.
11487 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11490 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11491 and the surrounding thread.
11492 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11493 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11494 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11496 * s/openbsd.h (BROKEN_SIGIO): Define.
11497 * unexelf.c (unexec) [__OpenBSD__]:
11498 Don't update the .mdebug section of the Alpha COFF symbol table.
11500 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11502 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11505 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11507 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11508 This fixes some race conditions on the permissions of any newly
11511 * alloc.c (valid_pointer_p): Use pipe, not open.
11512 This fixes some permissions issues when debugging.
11514 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11515 If fchown fails to set both uid and gid, try to set just gid,
11516 as that is sometimes allowed. Adjust the file's mode to eliminate
11517 setuid or setgid bits that are inappropriate if fchown fails.
11519 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11521 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11522 to compare Lisp_Objects.
11523 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11524 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11525 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11527 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11529 * lread.c (read_integer): Unread even EOF character.
11530 (read1): Likewise. Properly record start position of symbol.
11532 * lread.c (read1): Read `#:' as empty uninterned symbol if no
11533 symbol character follows.
11535 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11537 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11538 This works around a problem with the previous change to Fcopy_file.
11539 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11540 and without this change, GCC might complain about discarding
11541 fchown's return value.
11543 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11545 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11547 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11549 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11551 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11553 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11554 it's used from the C level.
11556 * process.c: Use the same condition for POLL_FOR_INPUT in both
11557 keyboard.c and process.c (bug#1858).
11559 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11561 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11562 (Fgnutls_boot): Use it.
11564 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11566 * doc.c (Fsubstitute_command_keys): Revert last change.
11568 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11570 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11571 quotes the next character, and doesn't affect other longer
11572 sequences (bug#8935).
11574 * lread.c (syms_of_lread): Clarify that is isn't only
11575 `eval-buffer' and `eval-defun' that's affected by
11576 `lexical-binding' (bug#8460).
11578 2011-07-15 Eli Zaretskii <eliz@gnu.org>
11580 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11581 bidi redisplay when a line includes both an image and is truncated.
11583 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11585 Fix minor problems found by static checking.
11586 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11587 (elsz): Now a signed constant, not a size_t var. We prefer signed
11588 types to unsigned, to avoid integer comparison confusion. Without
11589 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
11590 "cannot optimize loop, the loop counter may overflow", a symptom
11592 * indent.c (Fvertical_motion): Mark locals as initialized.
11593 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
11595 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
11597 * search.c (Fre_search_backward): Mention `case-fold-search' in
11598 all the re_search_* functions (bug#8138).
11600 * keyboard.c (Fopen_dribble_file): Document when the file is
11603 2011-07-14 Eli Zaretskii <eliz@gnu.org>
11605 * bidi.c (bidi_dump_cached_states): Fix format of displaying
11608 Support bidi reordering of display and overlay strings.

11611 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
11612 (reseat_to_string): Initialize bidi_it->string.s and
11613 bidi_it->string.schars.
11614 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
11615 NULL (avoids a crash in bidi_paragraph_init).
11616 Initialize itb.string.lstring.
11617 (init_iterator): Call bidi_init_it only of a valid
11618 buffer position was specified. Initialize paragraph_embedding to
11620 (reseat_to_string): Initialize the bidi iterator.
11621 (display_string): If we need to ignore text properties of
11622 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
11623 original value of -1 will not work with bidi.)
11624 (compute_display_string_pos): First arg is now struct
11625 `text_pos *'; all callers changed. Support display properties on
11627 (compute_display_string_end): Support display properties on Lisp
11629 (init_iterator, reseat_1, reseat_to_string): Initialize the
11630 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
11631 when iterating on a string not from display properties).
11632 (compute_display_string_pos, compute_display_string_end):
11633 Fix calculation of the object to scan. Fixes an error when using
11635 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
11636 base_level_stop; instead, set base_level_stop to BEGV.
11637 Fixes crashes in vertical-motion.
11638 (next_element_from_buffer): Improve commentary for when
11639 the iterator is before prev_stop.
11640 (init_iterator): Initialize bidi_p from the default value of
11641 bidi-display-reordering, not from buffer-local value. Use the
11642 buffer-local value only if initializing for buffer iteration.
11643 (handle_invisible_prop): Support invisible properties on strings
11644 that are being bidi-reordered.
11645 (set_iterator_to_next): Support bidi reordering of C strings and
11647 (next_element_from_string): Support bidi reordering of Lisp
11649 (handle_stop_backwards): Support Lisp strings as well.
11650 (display_string): Support display of R2L glyph rows.
11651 Use IT_STRING_CHARPOS when displaying from a Lisp string.
11652 (init_iterator): Don't initialize it->bidi_p for strings
11654 (reseat_to_string): Initialize it->bidi_p for strings here.
11655 (next_element_from_string, next_element_from_c_string)
11656 (next_element_from_buffer): Add xassert's for correspondence
11657 between IT's object being iterated and it->bidi_it.string
11659 (face_before_or_after_it_pos): Support bidi iteration.
11660 (next_element_from_c_string): Handle the case of the first string
11661 character that is not the first one in the visual order.
11662 (get_visually_first_element): New function, refactored from common
11663 parts of next_element_from_buffer, next_element_from_string, and
11664 next_element_from_c_string.
11665 (tool_bar_lines_needed, redisplay_tool_bar)
11666 (display_menu_bar): Force left-to-right direction. Add a FIXME
11667 comment for making that be controlled by a user option.
11668 (push_it, pop_it): Save and restore the state of the
11669 bidi iterator. Save and restore the bidi_p flag.
11670 (pop_it): Iterate out of display property for string iteration as
11672 (iterate_out_of_display_property): Support iteration over strings.
11673 (handle_single_display_spec): Set up it->bidi_it for iteration
11674 over a display string, and call bidi_init_it.
11675 (handle_single_display_spec, next_overlay_string)
11676 (get_overlay_strings_1, push_display_prop): Set up the bidi
11677 iterator for displaying display or overlay strings.
11678 (forward_to_next_line_start): Don't use the shortcut if
11680 (back_to_previous_visible_line_start): If handle_display_prop
11681 pushed the iterator stack, restore the internal state of the bidi
11682 iterator by calling bidi_pop_it same number of times.
11683 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
11684 and we are bidi-iterating, don't decrement the iterator position;
11685 instead, set the first_elt flag in the bidi iterator, to produce
11687 (reseat_1): Remove redundant setting of string_from_display_prop_p.
11688 (push_display_prop): xassert that we are iterating a buffer.
11689 (push_it, pop_it): Save and restore paragraph_embedding member.
11690 (handle_single_display_spec, next_overlay_string)
11691 (get_overlay_strings_1, reseat_1, reseat_to_string)
11692 (push_display_prop): Set up the `unibyte' member of bidi_it.string
11693 correctly. Don't assume unibyte strings are not bidi-reordered.
11694 (compute_display_string_pos)
11695 (compute_display_string_end): Fix handling the case of C string.
11696 (push_it, pop_it): Save and restore from_disp_prop_p.
11697 (handle_single_display_spec, push_display_prop): Set the
11698 from_disp_prop_p flag.
11699 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
11700 (pop_it): Call iterate_out_of_display_property only if we are
11701 popping after iteration over a string that came from a display
11702 property. Fix a typo in popping stretch info. Add an assertion
11703 for verifying that the iterator position is in sync with the bidi
11705 (handle_single_display_spec, get_overlay_strings_1)

12142 (parse_settings): Move check for font inside HAVE_XFT.
12143 (read_settings, apply_xft_settings): Add comment.
12144 (read_and_apply_settings): Add comment. Call map_tool_bar_style and

12156 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
12158 Random fixes. E.g., (random) never returned negative values.
12159 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
12160 subseconds part to the entropy, as that's a bit more random.
12161 Prefer signed to unsigned, since the signedness doesn't matter and
12162 in general we prefer signed. When given a limit, use a
12163 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12164 latter isn't right if USE_2_TAGS_FOR_INTS.
12165 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12166 not 0..VALMASK. Don't discard "excess" bits that random () returns.
12168 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
12170 * textprop.c (text_property_stickiness):
12171 Obey Vtext_property_default_nonsticky.

12179 This is more efficient than Ffile_directory_p and avoids a minor race.
12181 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
12183 * buffer.c (Foverlay_put): Say what the return value is
12186 * fileio.c (barf_or_query_if_file_exists): Check first if the file
12187 is a directory before asking whether to use the file name
12189 (barf_or_query_if_file_exists): Make the "File is a directory"
12190 error be more correct.
12192 * fns.c (Frequire): Remove the mention of the .gz files, since
12193 that's installation-specific, but keep the mention of
12194 `get-load-suffixes'.
12196 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
12198 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

12206 Qgnutls_bootprop_verify_error (which is no longer used).
12208 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
12209 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
12210 Also (re)move comments that are misplaced or no longer relevant.
12212 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12214 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

12242 * fns.c (Frequire): Mention .el.gz files (bug#7314).
12243 (Frequire): Mention get-load-suffixes.

12311 * eval.c (struct backtrace): Simplify and port the data structure.
12312 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12313 signed bit field, as this assumption is not portable and it makes
12314 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12315 "char debug_on_exit : 1" as this is not portable either; instead,
12316 use the portable "unsigned int debug_on_exit : 1". Remove unused
12317 member evalargs. Remove obsolete comments about cc bombing out.
12319 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
12321 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

12389 (emacs_fixed_get_preferred_height): Use min_width/height from
12390 frames size_hint to set minimum and natural (Bug#8919).
12391 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
12392 and use min_width/height from frames size_hint to set
12393 min_width/height (Bug#8919).

12485 * print.c (printchar, strout): Check for string overflow.
12486 (PRINTPREPARE, printchar, strout):
12487 Don't set size unless allocation succeeds.
12489 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
12490 for sizes. Check for string overflow more accurately.

12504 (read_integer): Radix is now EMACS_INT, not int,
12505 to improve quality of diagnostics for out-of-range radices.
12506 Calculate buffer size correctly for out-of-range radices.
12507 (read1): Check for integer overflow in radices, and in
12508 read-circle numbers.
12509 (read_escape): Avoid int overflow.
12510 (Fload, openp, read_buffer_size, read1)
12511 (substitute_object_recurse, read_vector, read_list, map_obarray):
12512 Use ptrdiff_t, not int, for sizes.

12534 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
12535 The following patches are for when GLYPH_DEBUG && !XASSERT.
12536 * dispextern.h (trace_redisplay_p, dump_glyph_string):
12537 * dispnew.c (flush_stdout):
12538 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
12539 Mark as externally visible.
12540 * dispnew.c (check_window_matrix_pointers): Now static.
12541 * dispnew.c (window_to_frame_vpos):
12542 * xfns.c (unwind_create_frame):

12549 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
12551 (debug_method_add): Use va_list and vsprintf rather than relying
12552 on undefined behavior with wrong number of arguments.
12553 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12554 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12555 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12556 since we're not interested in debugging glyphs with old libraries.
12557 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12558 GCC 4.6.0's static checking.
12560 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

12582 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
12584 Use ptrdiff_t, not int, for overlay counts.
12585 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
12586 * editfns.c (overlays_around, get_pos_property):
12587 * textprop.c (get_char_property_and_overlay):
12588 * xdisp.c (next_overlay_change, note_mouse_highlight):
12589 * xfaces.c (face_at_buffer_position):
12590 * buffer.c (OVERLAY_COUNT_MAX): New macro.
12591 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
12592 (Fnext_overlay_change, Fprevious_overlay_change)
12593 (mouse_face_overlay_overlaps, Foverlays_in):
12594 Use ptrdiff_t, not int, for sizes.
12595 (overlays_at, overlays_in): Check for size-calculation overflow.
12597 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
12599 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
12600 (x_session_initialize): Do not assume string length fits in int.
12602 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
12603 This is unlikely, but can occur if DPI is outlandish.
12605 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
12606 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
12608 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
12609 * xrdb.c (magic_file_p, search_magic_path):
12610 Omit last arg SUFFIX; it was always 0. All callers changed.
12611 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
12613 * xfont.c (xfont_match): Avoid need for strlen.
12615 * xfns.c: Don't assume strlen fits in int.
12616 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
12618 * xdisp.c (message_log_check_duplicate): Return intmax_t,
12619 not unsigned long, as we prefer signed integers. All callers changed.
12620 Detect integer overflow in repeat count.
12621 (message_dolog): Don't assume print length fits in 39 bytes.
12622 (display_mode_element): Don't assume strlen fits in int.
12624 * termcap.c: Don't assume sizes fit in int and never overflow.
12625 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
12626 (gobble_line): Check for size-calculation overflow.
12628 * minibuf.c (Fread_buffer):
12629 * lread.c (intern, intern_c_string):
12630 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
12631 Don't assume string length fits in int.
12633 * keyboard.c (parse_tool_bar_item):
12634 * gtkutil.c (style_changed_cb): Avoid need for strlen.
12636 * font.c: Don't assume string length fits in int.
12637 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
12638 Use ptrdiff_t, not int.
12639 (font_intern_prop): Don't assume string length fits in int.
12640 Don't assume integer property fits in fixnum.
12641 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
12643 * filelock.c: Fix some buffer overrun and integer overflow issues.
12644 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
12645 Reformulate so as not to need the command string.
12646 Invoke gzip -cd rather than gunzip, as it's more portable.
12647 (lock_info_type, lock_file_1, lock_file):
12648 Don't assume pid_t and time_t fit in unsigned long.
12649 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
12650 (current_lock_owner): Prefer signed type for sizes.
12651 Use memcpy, not strncpy, where memcpy is what is really wanted.
12652 Don't assume (via atoi) that time_t and pid_t fit in int.
12653 Check for time_t and/or pid_t out of range, e.g., via a network share.
12654 Don't alloca where an auto var works fine.
12656 * fileio.c: Fix some integer overflow issues.
12657 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
12658 Don't assume string length fits in int.
12659 (directory_file_name): Don't assume string length fits in long.
12660 (make_temp_name): Don't assume pid fits in int, or that its print
12661 length is less than 20.
12663 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
12665 * coding.c (make_subsidiaries): Don't assume string length fits in int.
12667 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
12669 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
12670 We prefer signed integers, even for size calculations.
12672 * emacs.c: Don't assume string length fits in 'int'.
12673 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
12674 (main): Don't invoke strlen when not needed.
12676 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
12677 (XD_DEBUG_MESSAGE): Don't waste a byte.
12679 * callproc.c (getenv_internal_1, getenv_internal)
12680 (Fgetenv_internal):
12681 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
12683 * lread.c (invalid_syntax): Omit length argument.
12684 All uses changed. This doesn't fix a bug, but it simplifies the
12685 code away from its former Hollerith-constant appearance, and it's
12686 one less 'int' to worry about when looking at integer-overflow issues.
12687 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
12689 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
12690 This didn't break anything, but it didn't help either.
12691 It's confusing to put a bogus integer in a place where the actual
12692 value does not matter.
12693 (LIST_END_P): Remove unused macro and its bogus comment.
12694 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
12696 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
12697 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
12699 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
12700 We prefer signed types, and the value cannot exceed the EMACS_INT
12701 range anyway (because otherwise the length would not be representable).
12702 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
12703 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
12704 This avoids a GCC warning when WIDE_EMACS_INT.
12706 * indent.c (sane_tab_width): New function.
12707 (current_column, scan_for_column, Findent_to, position_indentation)
12708 (compute_motion): Use it. This is just for clarity.
12709 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
12711 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
12713 * lisp.h (lint_assume): New macro.
12714 * composite.c (composition_gstring_put_cache):
12715 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
12717 * editfns.c, insdel.c:
12718 Omit unnecessary forward decls, to simplify future changes.
12720 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
12722 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
12724 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
12725 Use much-faster test for byte-length change.
12726 Don't assume string byte-length fits in 'int'.
12727 Check that character arg fits in 'int'.
12728 (mapcar1): Declare byte as byte, for clarity.
12730 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
12732 * fns.c (concat): Catch string overflow earlier.
12733 Do not rely on integer wraparound.
12735 * dispextern.h (struct it.overlay_strings_charpos)
12736 (struct it.selective): Now EMACS_INT, not int.
12737 * xdisp.c (forward_to_next_line_start)
12738 (back_to_previous_visible_line_start)
12739 (reseat_at_next_visible_line_start, next_element_from_buffer):
12740 Don't arbitrarily truncate the value of 'selective' to int.
12742 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
12744 * composite.c: Don't truncate sizes to 'int'.
12745 (composition_gstring_p, composition_reseat_it)
12746 (composition_adjust_point): Use EMACS_INT, not int.
12747 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
12748 not EMACS_UINT, for indexes.
12750 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
12752 * buffer.c: Include <verify.h>.
12753 (struct sortvec.priority, struct sortstr.priority):
12754 Now EMACS_INT, not int.
12755 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
12756 (struct sortstr.size, record_overlay_string)
12757 (struct sortstrlist.size, struct sortlist.used):
12758 Don't truncate size to int.
12759 (record_overlay_string): Check for size-calculation overflow.
12760 (init_buffer_once): Check at compile-time, not run-time.
12762 2011-06-22 Jim Meyering <meyering@redhat.com>
12764 Don't leak an XBM-image-sized buffer
12765 * image.c (xbm_load): Free the image buffer after using it.
12767 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
12770 * composite.c (find_automatic_composition): Omit needless 'return 0;'
12771 that Sun C diagnosed.
12772 * fns.c (secure_hash): Fix pointer signedness issue.
12773 * intervals.c (static_offset_intervals): New function.
12774 (offset_intervals): Use it.
12776 2011-06-21 Leo Liu <sdl.web@gmail.com>
12779 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
12782 * fns.c (secure_hash): Rename from crypto_hash_function and change
12783 the first arg to accept symbols.
12784 (Fsecure_hash): New primitive.
12785 (syms_of_fns): New symbols.
12787 2011-06-20 Deniz Dogan <deniz@dogan.se>
12789 * process.c (Fset_process_buffer): Clarify return value in
12792 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
12794 * dispnew.c (add_window_display_history): Use BVAR.
12796 * xdisp.c (debug_method_add): Use BVAR.
12797 (check_window_end, dump_glyph_matrix, dump_glyph)
12798 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
12800 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
12803 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
12804 check till after the cache is created in init_frame_faces.
12806 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
12808 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
12810 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
12812 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
12813 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
12814 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
12816 Improve buffer-overflow checking (Bug#8873).
12817 * fileio.c (Finsert_file_contents):
12818 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
12819 Remove the old (too-loose) buffer overflow checks.
12820 They weren't needed, since make_gap checks for buffer overflow.
12821 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
12822 The old code merely checked for Emacs fixnum overflow, and relied
12823 on undefined (wraparound) behavior. The new code avoids undefined
12824 behavior, and also checks for ptrdiff_t and/or size_t overflow.
12826 * editfns.c (Finsert_char): Don't dump core with very negative counts.
12827 Tune. Don't use wider integers than needed. Don't use alloca.
12828 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
12830 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
12832 * insdel.c, lisp.h (buffer_overflow): New function.
12833 (insert_from_buffer_1, replace_range, replace_range_2):
12834 * insdel.c (make_gap_larger):
12835 * editfns.c (Finsert_char):
12836 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
12838 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
12840 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
12842 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
12844 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
12845 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
12847 * fileio.c: Don't assume EMACS_INT fits in off_t.
12848 (emacs_lseek): New static function.
12849 (Finsert_file_contents, Fwrite_region): Use it.
12850 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
12852 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
12854 * fns.c: Don't overflow int when computing a list length.
12855 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
12856 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
12857 truncation on 64-bit hosts. Check for QUIT every
12858 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
12859 faster and is responsive enough.
12860 (Flength): Report an error instead of overflowing an integer.
12861 (Fsafe_length): Return a float if the value is not representable
12862 as a fixnum. This shouldn't happen except in contrived situations.
12863 (Fnthcdr, Fsort): Don't assume list length fits in int.
12864 (Fcopy_sequence): Don't assume vector length fits in int.
12866 * alloc.c: Check that resized vectors' lengths fit in fixnums.
12867 (header_size, word_size): New constants.
12868 (allocate_vectorlike): Don't check size overflow here.
12869 (allocate_vector): Check it here instead, since this is the only
12870 caller of allocate_vectorlike that could cause overflow.
12871 Check that the new vector's length is representable as a fixnum.
12873 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
12874 The previous code was bogus. For example, next_almost_prime (32)
12875 returned 39, which is undesirable as it is a multiple of 3; and
12876 next_almost_prime (24) returned 25, which is a multiple of 5 so
12877 why was the code bothering to check for multiples of 7?
12879 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
12881 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
12883 Variadic C functions now count arguments with ptrdiff_t.
12884 This partly undoes my 2011-03-30 change, which replaced int with size_t.
12885 Back then I didn't know that the Emacs coding style prefers signed int.
12886 Also, in the meantime I found a few more instances where arguments
12887 were being counted with int, which may truncate counts on 64-bit
12888 machines, or EMACS_INT, which may be unnecessarily wide.
12889 * lisp.h (struct Lisp_Subr.function.aMANY)
12890 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
12891 Arg counts are now ptrdiff_t, not size_t.
12892 All variadic functions and their callers changed accordingly.
12893 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
12894 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
12895 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
12896 * callint.c (Fcall_interactively): Check arg count for overflow,
12897 to avoid potential buffer overrun. Use signed char, not 'int',
12898 for 'varies' array, so that we needn't bother to check its size
12899 calculation for overflow.
12900 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
12901 * eval.c (apply_lambda):
12902 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
12903 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
12904 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
12906 * callint.c (Fcall_interactively): Don't use index var as event count.
12908 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
12909 * mem-limits.h (SIZE): Remove; no longer used.
12911 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
12913 Remove unnecessary casts.
12914 * xterm.c (x_term_init):
12915 * xfns.c (x_set_border_pixel):
12916 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
12917 These aren't needed now that we assume ANSI C.
12919 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
12920 It's more likely to cause problems (due to unsigned overflow)
12923 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
12925 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
12927 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
12929 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
12931 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
12933 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
12935 GLYPH_CODE_FACE returns EMACS_INT, not int.
12936 * dispextern.h (merge_faces):
12937 * xfaces.c (merge_faces):
12938 * xdisp.c (get_next_display_element, next_element_from_display_vector):
12939 Don't assume EMACS_INT fits in int.
12941 * character.h (CHAR_VALID_P): Remove unused parameter.
12942 * fontset.c, lisp.h, xdisp.c: All uses changed.
12944 * editfns.c (Ftranslate_region_internal): Omit redundant test.
12946 * fns.c (concat): Minor tuning based on overflow analysis.
12947 This doesn't fix any bugs. Use int to hold character, instead
12948 of constantly refetching from Emacs object. Use XFASTINT, not
12949 XINT, for value known to be a character. Don't bother comparing
12950 a single byte to 0400, as it's always less.
12952 * floatfns.c (Fexpt):
12953 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
12955 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
12958 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
12960 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
12961 Without this fix, on a 64-bit host (aset S 0 4294967386) would
12962 incorrectly succeed when S was a string, because 4294967386 was
12963 truncated before it was used.
12965 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
12966 Otherwise, an out-of-range integer could cause undefined behavior
12969 * composite.c: Use int, not EMACS_INT, for characters.
12970 (fill_gstring_body, composition_compute_stop_pos): Use int, not
12971 EMACS_INT, for values that are known to be in character range.
12972 This doesn't fix any bugs but is the usual style inside Emacs and
12973 may generate better code on 32-bit machines.
12975 Make sure a 64-bit char is never passed to ENCODE_CHAR.
12976 This is for reasons similar to the recent CHAR_STRING fix.
12977 * charset.c (Fencode_char): Check that character arg is actually
12978 a character. Pass an int to ENCODE_CHAR.
12979 * charset.h (ENCODE_CHAR): Verify that the character argument is no
12980 wider than 'int', as a compile-time check to prevent future regressions
12983 * character.c (char_string): Remove unnecessary casts.
12985 Make sure a 64-bit char is never passed to CHAR_STRING.
12986 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
12987 by silently ignoring the top 32 bits, allowing some values
12988 that were far too large to be valid characters.
12989 * character.h: Include <verify.h>.
12990 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
12991 arguments are no wider than unsigned, as a compile-time check
12992 to prevent future regressions in this area.
12994 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
12995 (Fsubst_char_in_region):
12997 * xdisp.c (decode_mode_spec_coding):
12998 Adjust to CHAR_STRING's new requirement.
12999 * editfns.c (Finsert_char, Fsubst_char_in_region):
13000 * fns.c (concat): Check that character args are actually
13001 characters. Without this test, these functions did the wrong
13002 thing with wildly out-of-range values on 64-bit hosts.
13004 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13005 These casts should not be needed on 32-bit hosts, either.
13006 * keyboard.c (read_char):
13007 * lread.c (Fload): Remove casts to unsigned.
13009 * lisp.h (UNSIGNED_CMP): New macro.
13010 This fixes comparison bugs on 64-bit hosts.
13011 (ASCII_CHAR_P): Use it.
13012 * casefiddle.c (casify_object):
13013 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
13014 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
13015 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
13016 * dispextern.h (FACE_FROM_ID):
13017 * keyboard.c (read_char): Use UNSIGNED_CMP.
13019 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
13020 not to EMACS_INT, to avoid GCC warning.
13022 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13024 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13025 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and

13057 These were 'int' variables that could overflow on 64-bit hosts;
13058 they were never used, so remove them instead of repairing them.

13067 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13068 when a (possibly-narrower) signed value would do just as well.
13069 We prefer using signed arithmetic, to avoid comparison confusion.
13071 * alloc.c: Catch some string size overflows that we were missing.
13072 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
13073 for convenience in STRING_BYTES_MAX.
13074 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
13075 The definition here is exact; the one in lisp.h was approximate.
13076 (allocate_string_data): Check for string overflow. This catches
13077 some instances we weren't catching before. Also, it catches
13078 size_t overflow on (unusual) hosts where SIZE_MAX <= min
13079 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
13080 and ptrdiff_t and EMACS_INT are both 64 bits.
13082 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
13083 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.

13526 Minor fixes for signed vs unsigned integers.
13527 * character.h (MAYBE_UNIFY_CHAR):
13528 * charset.c (maybe_unify_char):

13531 * ftfont.c (ftfont_spec_pattern):
13532 * keymap.c (access_keymap, silly_event_symbol_error):
13533 XUINT -> XFASTINT, since the integer must be nonnegative.
13534 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
13535 since it makes no difference and we prefer signed.
13536 * keyboard.c (record_char): Use XUINT when all the neighbors do.
13537 (access_keymap): NATNUMP -> INTEGERP, since the integer must be

13588 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
13589 Do not assume that spare memory exists; that assumption is valid
13590 only if SYSTEM_MALLOC.
13591 (LARGE_REQUEST): New macro, so that the issue of large requests

13651 Support character positions inside a run of characters covered by a
13653 (bidi_paragraph_init, bidi_resolve_explicit_1)
13654 (bidi_level_of_next_char): Call bidi_fetch_char and
13655 bidi_fetch_char_advance instead of FETCH_CHAR and

13658 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
13660 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
13661 instead of using explicit *_CHAR codes.
13662 (bidi_resolve_explicit, bidi_resolve_weak):
13663 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
13664 bidirectional text is supported only in multibyte buffers.
13665 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
13666 it to initialize the frame_window_p member of struct bidi_it.

13671 (bidi_level_of_next_char): Don't try to lookup the cache for the
13672 next/previous character if nothing is cached there yet, or if we
13673 were just reseat()'ed to a new position.
13675 * xdisp.c (set_cursor_from_row): Set start and stop points
13676 according to the row's direction when priming the loop that looks
13677 for the glyph on which to display cursor.
13678 (single_display_spec_intangible_p): Function deleted.
13679 (display_prop_intangible_p): Reimplement to call
13680 handle_display_spec instead of single_display_spec_intangible_p.
13681 Accept 3 additional arguments needed by handle_display_spec.
13682 This fixes incorrect cursor motion across display property with complex
13683 values: lists, `(when COND...)' forms, etc.

13685 lists with the argument STRING its top-level element.
13686 (display_prop_string_p): Fix the condition for processing a
13687 property that is a list to be consistent with handle_display_spec.
13688 (handle_display_spec): New function, refactored from the
13689 last portion of handle_display_prop.
13690 (compute_display_string_pos): Accept additional argument
13691 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
13692 value of a `display' property is a "replacing spec".
13693 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
13694 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
13695 the display property, but just return a value indicating whether
13696 the display property will replace the characters it covers.
13697 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
13698 frame_window_p members of struct bidi_it.
13699 (compute_display_string_pos, compute_display_string_end):
13701 (push_it): Accept second argument POSITION, where pop_it should
13702 jump to continue iteration.
13703 (reseat_1): Initialize bidi_it.disp_pos.
13705 * keyboard.c (adjust_point_for_property): Adjust the call to
13706 display_prop_intangible_p to its new signature.
13708 * dispextern.h (struct bidi_it): New member frame_window_p.
13709 (bidi_init_it): Update prototypes.
13710 (display_prop_intangible_p): Update prototype.
13711 (compute_display_string_pos, compute_display_string_end):

13720 * lisp.h: Change signatures accordingly.
13721 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
13722 All callers changed. (Bug#8762)
13724 * gnutls.c: Use Emacs's memory allocators.
13725 Without this change, the gnutls library would invoke malloc etc.
13726 directly, which causes problems on non-SYNC_INPUT hosts, and which
13727 runs afoul of improving memory_full behavior. (Bug#8761)
13728 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
13729 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
13730 xfree instead of the default malloc, realloc, free.
13731 (Fgnutls_boot): No need to check for memory allocation failure,
13732 since xmalloc does that for us.
13734 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
13735 * category.c (hash_get_category_set):
13736 * ccl.c (ccl_driver):
13737 * charset.c (Fdefine_charset_internal):

13748 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
13749 (Fsxhash, Fgethash, Fputhash, Fmaphash):
13750 * image.c (make_image, search_image_cache, lookup_image)
13751 (xpm_put_color_table_h):
13752 * lisp.h (struct Lisp_Hash_Table):
13753 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
13754 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
13755 for hashes and hash indexes, instead of 'unsigned' and 'int'.
13756 * alloc.c (allocate_vectorlike):
13757 Check for overflow in vector size calculations.
13758 * ccl.c (ccl_driver):
13759 Check for overflow when converting EMACS_INT to int.
13760 * fns.c, image.c: Remove unnecessary static decls that would otherwise
13761 need to be updated by these changes.
13762 * fns.c (make_hash_table, maybe_resize_hash_table):
13763 Check for integer overflow with large hash tables.
13764 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
13765 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
13766 (SXHASH_REDUCE): New macro.
13767 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
13768 Use it instead of discarding useful hash info with large hash values.
13769 (sxhash_float): New function.
13770 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
13771 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
13772 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
13773 Rewrite to use FIXNUM_BITS, as this simplifies things.
13774 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
13775 Adjust signatures to match updated version of code.
13776 (consing_since_gc): Now EMACS_INT, since a single hash table can
13777 use more than INT_MAX bytes.

13826 Make it possible to run ./temacs.
13828 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
13829 syms_of_callproc does the same thing. Remove test for
13830 "initialized", do it in the caller.
13831 * emacs.c (main): Avoid calling set_initial_environment when dumping.
13833 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>

13851 * eval.c (Qdebug): Now static.
13852 * lisp.h (Qdebug): Remove decl. This reverts a part of the
13853 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
13854 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.

13890 * fns.c (to_uchar): Define.
13891 (crypto_hash_function): Use it to convert some newly-signed
13892 variables to unsigned, to avoid sign-extension bugs. For example,
13893 without this change, (md5 "truc") would evaluate to
13894 45723a2aff78ff4fff7fff1114760e62 rather than the expected
13895 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
13896 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
13898 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13900 Integer overflow fixes.
13902 * dbusbind.c: Serial number integer overflow fixes.
13903 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
13904 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
13905 to hold a serial number that is too large for a fixnum.
13906 (Fdbus_method_return_internal, Fdbus_method_error_internal):
13907 Check for serial numbers out of range. Decode any serial number
13908 that was so large that it became a float. (Bug#8722)
13910 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
13911 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13912 Use XFASTINT rather than XUINT when numbers are nonnegative.
13913 (xd_append_arg, Fdbus_method_return_internal):
13914 (Fdbus_method_error_internal): Likewise. Also, for unsigned
13915 arguments, check that Lisp number is nonnegative, rather than
13916 silently wrapping negative numbers around. (Bug#8722)
13917 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
13920 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
13922 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
13924 ccl: Add integer overflow checks.
13925 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
13926 (IN_INT_RANGE): New macros.
13927 (ccl_driver): Use them to check for integer overflow when
13928 decoding a CCL program. Many of the new checks are whether XINT (x)
13929 fits in int; it doesn't always, on 64-bit hosts. The new version
13930 doesn't catch all possible integer overflows, but it's an
13931 improvement. (Bug#8719)
13933 * alloc.c (make_event_array): Use XINT, not XUINT.
13934 There's no need for unsigned here.
13936 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
13937 This follows up to the 2011-05-06 change that substituted uintptr_t
13938 for EMACS_INT. This case wasn't caught back then.
13940 Rework Fformat to avoid integer overflow issues.
13941 * editfns.c: Include <float.h> unconditionally, as it's everywhere
13942 now (part of C89). Include <verify.h>.
13943 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
13944 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
13945 (Fformat): Avoid the prepass trying to compute sizes; it was only
13946 approximate and thus did not catch overflow reliably. Instead, walk
13947 through the format just once, formatting and computing sizes as we go,
13948 checking for integer overflow at every step, and allocating a larger
13949 buffer as needed. Keep track separately whether the format is
13950 multibyte. Keep only the most-recently calculated precision, rather
13951 than them all. Record whether each argument has been converted to
13952 string. Use EMACS_INT, not int, for byte and char and arg counts.
13953 Support field widths and precisions larger than INT_MAX. Avoid
13954 sprintf's undefined behavior with conversion specifications such as %#d
13955 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
13956 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
13957 formatting out-of-range floating point numbers with int
13958 formats. (Bug#8668)
13960 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
13962 * data.c: Avoid integer truncation in expressions involving floats.
13963 * data.c: Include <intprops.h>.
13964 (arith_driver): When there's an integer overflow in an expression
13965 involving floating point, convert the integers to floating point
13966 so that the resulting value does not suffer from catastrophic
13967 integer truncation. For example, on a 64-bit host (* 4
13968 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
13969 Do not rely on undefined behavior after integer overflow.
13971 merge count_size_as_multibyte, parse_str_to_multibyte
13972 * character.c, character.h (count_size_as_multibyte):
13973 Rename from parse_str_to_multibyte; all uses changed.
13974 Check for integer overflow.
13975 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
13976 since it's now a duplicate of the other. This is more of
13977 a character than a buffer op, so better that it's in character.c.
13978 * fns.c, print.c: Adjust to above changes.
13980 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
13982 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
13984 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13986 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13987 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
13988 (x_clipboard_manager_save): Now static.
13989 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
13991 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13992 (crypto_hash_function): Now static.
13993 Fix pointer signedness problems. Avoid unnecessary initializations.
13995 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
13997 * termhooks.h (Vselection_alist): Make it terminal-local.
13999 * terminal.c (create_terminal): Initialize it.
14001 * xselect.c: Support for clipboard managers.
14002 (Vselection_alist): Move to termhooks.h as terminal-local var.
14003 (LOCAL_SELECTION): New macro.
14004 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14005 (symbol_to_x_atom): Remove gratuitous arg.
14006 (x_handle_selection_request, lisp_data_to_selection_data)
14007 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14008 (x_own_selection, x_get_local_selection, x_convert_selection):
14009 New arg, specifying work frame. Use terminal-local Vselection_alist.
14010 (some_frame_on_display): Delete unused function.
14011 (Fx_own_selection_internal, Fx_get_selection_internal)
14012 (Fx_disown_selection_internal, Fx_selection_owner_p)
14013 (Fx_selection_exists_p): New optional frame arg.
14014 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14015 (x_handle_selection_clear): Don't treat other terminals with the
14016 same keyboard specially. Use the terminal-local Vselection_alist.
14017 (x_clear_frame_selections): Use Frun_hook_with_args.
14019 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14021 * xterm.h: Add support for those atoms.
14023 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14025 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14026 (converted_selections, conversion_fail_tag): New global variables.
14027 (x_selection_request_lisp_error): Free the above.
14028 (x_get_local_selection): Remove unnecessary code.
14029 (x_reply_selection_request): Args changed; handle arbitrary array
14030 of converted selections stored in converted_selections.
14031 Separate the XChangeProperty and SelectionNotify steps.
14032 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14033 (x_convert_selection): New function.
14034 (x_handle_selection_event): Simplify.
14035 (x_get_foreign_selection): Don't ignore incoming requests while
14036 waiting for an answer; this will fail when we implement
14037 SAVE_TARGETS, and seems unnecessary anyway.
14038 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14039 (Vx_sent_selection_functions): Doc fix.
14041 2011-05-26 Leo Liu <sdl.web@gmail.com>
14043 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14045 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14047 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14049 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14050 for fringe update if it has periodic bitmap.
14051 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14052 and fringe_bitmap_periodic_p.
14054 * fringe.c (get_fringe_bitmap_data): New function.
14055 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14056 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14057 row. Mark glyph row for fringe update if periodicity changed.
14059 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14060 for fringe update unless it has periodic bitmap.
14062 2011-05-25 Kenichi Handa <handa@m17n.org>
14064 * xdisp.c (get_next_display_element): Set correct it->face_id for
14065 a static composition.
14067 2011-05-24 Leo Liu <sdl.web@gmail.com>
14070 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
14072 * fns.c (crypto_hash_function, Fsha1): New function.
14073 (Fmd5): Use crypto_hash_function.
14074 (syms_of_fns): Add Ssha1.
14076 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14078 * gnutls.c: Remove unused macros.
14079 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14080 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14081 Remove macros that are defined and never used.
14082 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14084 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14086 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14087 (Fx_get_selection_internal): Minor cleanup.
14088 (Fx_own_selection_internal): Rename arguments for consistency with
14091 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14093 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
14095 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14097 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
14099 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14101 * dispnew.c (scrolling_window): Don't exclude the case that the
14102 last enabled row in the desired matrix touches the bottom boundary.
14104 2011-05-21 Glenn Morris <rgm@gnu.org>
14106 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
14107 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
14108 and add some more files.
14110 2011-05-20 Eli Zaretskii <eliz@gnu.org>
14112 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
14113 report_file_error introduced by the change from 2011-05-07.
14115 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14117 * systime.h (Time): Define only if emacs is defined.
14118 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14119 where the include path doesn't have X11/X.h by default. See
14120 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14122 2011-05-20 Kenichi Handa <handa@m17n.org>
14124 * composite.c (find_automatic_composition): Fix previous change.
14126 2011-05-20 Glenn Morris <rgm@gnu.org>
14128 * lisp.mk: New file, split from Makefile.in.
14129 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14130 (shortlisp): Remove.
14131 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14133 2011-05-19 Glenn Morris <rgm@gnu.org>
14135 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14136 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14137 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14138 (lisp): Set the order to that of loadup.el.
14139 (shortlisp): Make it a copy of $lisp.
14140 (SOME_MACHINE_LISP): Remove.
14141 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14142 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14144 2011-05-18 Kenichi Handa <handa@m17n.org>
14146 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14147 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14148 (find_automatic_composition): Mostly rewrite for efficiency.
14150 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14152 * makefile.w32-in: Update dependencies.
14154 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14156 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14157 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14159 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14161 Fix some integer overflow issues, such as string length overflow.
14163 * insdel.c (count_size_as_multibyte): Check for string overflow.
14165 * character.c (lisp_string_width): Check for string overflow.
14166 Use EMACS_INT, not int, for string indexes and lengths; in
14167 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14168 the resulting string length overflows an EMACS_INT; instead,
14169 report a string overflow if no precision given. When checking for
14170 precision exhaustion, use a check that cannot possibly have
14171 integer overflow. (Bug#8675)
14172 * character.h (lisp_string_width): Adjust to new signature.
14174 * alloc.c (string_overflow): New function.
14175 (Fmake_string): Use it. This doesn't change behavior, but saves
14176 a few bytes and will simplify future changes.
14177 * character.c (string_escape_byte8): Likewise.
14178 * lisp.h (string_overflow): New decl.
14180 Fixups, following up to the user-interface timestamp change.
14181 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14182 for UI timestamps, instead of unsigned long.
14183 * msdos.c (mouse_get_pos): Likewise.
14184 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14185 * w32gui.h (Time): Define by including "systime.h" rather than by
14186 declaring it ourselves. (Bug#8664)
14188 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14189 * image.c (clear_image_cache): Likewise.
14191 * term.c (term_mouse_position): Don't assume time_t wraparound.
14193 Be more systematic about user-interface timestamps.
14194 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14195 and sometimes 'EMACS_UINT', to represent these timestamps.
14196 This change causes it to use 'Time' uniformly, as that's what X uses.
14197 This makes the code easier to follow, and makes it easier to catch
14198 integer overflow bugs such as Bug#8664.
14199 * frame.c (Fmouse_position, Fmouse_pixel_position):
14200 Use Time, not unsigned long, for user-interface timestamps.
14201 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14202 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14203 * keyboard.h (last_event_timestamp): Likewise.
14204 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14205 * menu.h (xmenu_show): Likewise.
14206 * term.c (term_mouse_position): Likewise.
14207 * termhooks.h (struct input_event.timestamp): Likewise.
14208 (struct terminal.mouse_position_hook): Likewise.
14209 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14210 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14211 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14212 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14213 what it was before.
14214 * menu.h, termhooks.h: Include "systime.h", for Time.
14216 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14217 Don't assume that the difference between two unsigned long values
14218 can fit into an integer. At this point, we know button_down_time
14219 <= event->timestamp, so the difference must be nonnegative, so
14220 there's no need to cast the result if double-click-time is
14221 nonnegative, as it should be; check that it's nonnegative, just in
14222 case. This bug is triggered when events are more than 2**31 ms
14223 apart (about 25 days). (Bug#8664)
14225 * xselect.c (last_event_timestamp): Remove duplicate decl.
14226 (x_own_selection): Remove needless cast to unsigned long.
14228 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14229 that always fit in int. Use a sentinel instead of a counter, to
14230 avoid a temp and to allay GCC's concerns about possible int overflow.
14231 * frame.h (struct frame): Use int for menu_bar_items_used
14232 instead of EMACS_INT, since it always fits in int.
14234 * menu.c (grow_menu_items): Check for int overflow.
14236 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14238 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14239 Before, the code was not consistent. These values cannot exceed
14240 2**31 - 1 so there's no need to make them unsigned.
14241 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14242 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14243 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14245 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14247 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14248 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14249 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14250 presumably because the widths might not match.
14252 * window.c (size_window): Avoid needless test at loop start.
14254 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14256 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14258 2011-05-12 Drew Adams <drew.adams@oracle.com>
14260 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14262 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14264 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14265 `width' to `bar_area_x' and `bar_area_width', respectively.
14266 (x_scroll_run): Take account of fringe background extension.
14268 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14269 Rename local vars `left' and `width' to `bar_area_x' and
14270 `bar_area_width', respectively.
14271 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14272 background extension.
14274 2011-05-10 Jim Meyering <meyering@redhat.com>
14276 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14278 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14280 * image.c (Finit_image_library): Return t for built-in image types,
14281 like pbm and xbm. (Bug#8640)
14283 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14285 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14287 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14289 * w32console.c (Fset_screen_color): Doc fix.
14290 (Fget_screen_color): New function.
14291 (syms_of_ntterm): Defsubr it.
14293 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14294 unlink the temporary file if Fcall_process didn't create it in the
14296 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14297 child process will be redirected to a file specified with `:file'.
14298 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14299 cue to call_process_cleanup not to close that handle.
14301 2011-05-07 Ben Key <bkey76@gmail.com>
14303 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14304 one of two shell specific rules, either bootstrap-temacs-CMD or
14305 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14306 to the previous implementation of the bootstrap-temacs rule.
14307 The bootstrap-temacs-CMD rule is similar to the previous
14308 implementation of the bootstrap-temacs rule except that it
14309 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14312 These changes, along with some changes to nt/configure.bat,
14313 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14314 earlier fix to add support for --cflags and --ldflags options
14315 that include quotes so that it works whether make uses cmd or
14318 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14320 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14321 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14323 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14324 a string. Handle both cases.
14325 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14326 (Fdbus_register_method): Use Qinvalid_function.
14328 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14330 * makefile.w32-in: Update dependencies.
14331 (LISP_H): Add inttypes.h and stdin.h.
14332 (PROCESS_H): Add unistd.h.
14334 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14336 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14337 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14339 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14341 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14343 * term.c (vfatal): Remove stray call to va_end.
14344 It's not needed and the C Standard doesn't allow it here anyway.
14346 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14347 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14349 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14352 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14354 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14356 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14358 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14360 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14362 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14363 * charset.c (Fdefine_charset_internal): Don't initialize
14364 charset.code_space[15]. The value was garbage, on hosts with
14365 32-bit int (Bug#8600).
14367 * lread.c (read_integer): Be more consistent with string-to-number.
14368 Use string_to_number to do the actual conversion; this avoids
14369 rounding errors and fixes some other screwups. Without this fix,
14370 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14371 (digit_to_number): Move earlier, for benefit of read_integer.
14372 Return -1 if the digit is out of range for the base, -2 if it is
14373 not a digit in any supported base. (Bug#8602)
14375 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14377 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14378 to match comment at start of function. This also removes a
14379 GCC warning about overflow in a 32+64-bit port.
14381 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14383 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14384 Reported by Stefan Monnier in
14385 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14386 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14387 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14389 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14390 (EMACS_UINTPTR): Likewise, with uintptr_t.
14392 * lisp.h: Prefer 64-bit EMACS_INT if available.
14393 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14394 on 32-bit hosts that have 64-bit int, so that they can access
14396 However, temporarily disable this change unless the temporary
14397 symbol WIDE_EMACS_INT is defined.
14399 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14401 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14402 This removes an assumption that EMACS_INT and long are the same
14403 width as pointers. The assumption is true for Emacs porting targets
14404 now, but we want to make other targets possible.
14405 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14406 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14407 In the rest of the code, change types of integers that hold casted
14408 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14409 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14410 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14411 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14412 No need to cast type when ORing.
14413 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14414 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14415 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14416 assume EMACS_INT is the same width as char *.
14417 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14418 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14419 Remove no-longer-needed casts.
14420 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14421 (xg_tool_bar_help_callback, xg_make_tool_item):
14422 Use EMACS_INTPTR to hold an integer
14423 that will be cast to void *; this can avoid a GCC warning
14424 if EMACS_INT is not the same width as void *.
14425 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14426 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14427 (current_message_1, set_message_1):
14428 Use a local to convert to proper width without a cast.
14429 * xmenu.c (dialog_selection_callback): Likewise.
14431 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14432 Also, don't assume VALBITS / RAND_BITS is less than 5,
14433 and don't rely on undefined behavior when shifting a 1 left into
14435 * lisp.h (get_random): Change signature to match.
14437 * lread.c (hash_string): Use size_t, not int, for hash computation.
14438 Normally we prefer signed values; but hashing is special, because
14439 it's better to use unsigned division on hash table sizes so that
14440 the remainder is nonnegative. Also, size_t is the natural width
14441 for hashing into memory. The previous code used 'int', which doesn't
14442 retain enough info to hash well into very large tables.
14443 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14445 * dbusbind.c: Don't possibly lose pointer info when converting.
14446 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14447 Use XPNTR rather than XHASH, so that the high-order bits of
14448 the pointer aren't lost when converting through void *.
14450 * eval.c (Fautoload): Don't double-shift a pointer.
14452 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14454 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14456 * gnutls.c (DEF_GNUTLS_FN):
14457 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14459 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14461 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14464 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14466 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14467 New version that can reserve upto 2GB of heap space.
14469 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14471 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14473 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14475 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14476 `gnutls_certificate_set_x509_key_file'.
14478 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
14480 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
14481 Update dependencies.
14483 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14485 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14486 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14487 Remove unused parameter `fildes'.
14488 * process.c (read_process_output, send_process): Don't pass it.
14490 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14492 Fix previous change: the library cache is defined in w32.c.
14493 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14494 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14496 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14498 Implement dynamic loading of GnuTLS on Windows.
14500 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14501 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14502 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14505 * gnutls.c (Qgnutls_dll): Define.
14506 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
14507 (gnutls_*): Declare function pointers.
14508 (init_gnutls_functions): New function to initialize function pointers.
14509 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
14510 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
14511 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14512 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
14513 (emacs_gnutls_write, emacs_gnutls_read)
14514 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14515 (Fgnutls_available_p): New function.
14516 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
14517 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
14518 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
14520 * image.c: Include w32.h.
14521 (Vimage_type_cache): Delete.

14524 (w32_delayed_load): Move to w32.c.
14526 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
14528 * w32.c (QCloaded_from, Vlibrary_cache): Define.
14529 (w32_delayed_load): Move from image.c. When loading a library, record
14530 its filename in the :loaded-from property of the library id.
14531 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
14532 Initialize and staticpro them.
14533 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
14535 * process.c: Include lisp.h before w32.h, not after.
14536 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
14537 instead of gnutls_record_check_pending.
14539 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
14541 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
14543 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
14544 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
14547 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
14549 * xterm.c (x_set_frame_alpha): Do not set property on anything
14550 else than FRAME_X_OUTER_WINDOW (Bug#8608).
14552 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14554 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
14556 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14558 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
14559 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

14568 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
14570 * callproc.c: Indentation fixup.
14572 * sysdep.c (wait_for_termination_1): Make static.
14573 (wait_for_termination, interruptible_wait_for_termination):
14574 Move after wait_for_termination_1.
14576 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
14578 * sysdep.c (interruptible_wait_for_termination): New function
14579 which is like wait_for_termination, but allows keyboard
14582 * callproc.c (Fcall_process): Add (:file "file") as an option for
14584 (Fcall_process_region): Ditto.
14586 2011-04-30 Eli Zaretskii <eliz@gnu.org>
14588 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
14589 rather than `XVECTOR (FOO)->size'.
14591 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
14592 inttypes.h, as a gnulib replacement is used if it not available in
14595 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14597 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
14598 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
14599 of MOST_POSITIVE_FIXNUM. (Bug#8528)
14601 * coding.c (coding_alloc_by_realloc): Error out if destination
14602 will grow beyond MOST_POSITIVE_FIXNUM.
14603 (decode_coding_emacs_mule): Abort if there isn't enough place in
14604 charbuf for the composition carryover bytes. Reserve an extra
14605 space for up to 2 characters produced in a loop.
14606 (decode_coding_iso_2022): Abort if there isn't enough place in
14607 charbuf for the composition carryover bytes.
14609 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14611 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
14612 aborting when %lld or %lll format is passed.
14613 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
14614 %llo or %llx format is passed. (Bug#8545)
14616 * window.c (window_scroll_line_based): Use a marker instead of
14617 simple variables to record original value of point. (Bug#7952)
14619 * doprnt.c (doprnt): Fix the case where a multibyte sequence
14620 produced by %s or %c overflows available buffer space. (Bug#8545)
14622 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
14624 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
14625 (SIZE_MAX): Move defn after all includes, as they might #define it.
14627 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14629 * w32.c (init_environment): Warn about defaulting HOME to C:\.
14631 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14633 * keyboard.c (Qdelayed_warnings_hook): Define.
14634 (command_loop_1): Run `delayed-warnings-hook'

14636 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
14637 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
14639 2011-04-28 Eli Zaretskii <eliz@gnu.org>
14641 * doprnt.c (doprnt): Don't return value smaller than the buffer
14642 size if the message was truncated. (Bug#8545).
14644 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14646 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

14649 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14651 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
14653 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
14655 * makefile.w32-in: Update dependencies.
14657 2011-04-27 Eli Zaretskii <eliz@gnu.org>
14659 Improve `doprnt' and its usage. (Bug#8545)
14660 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
14661 `format_end'. Remove support for %l as a conversion specifier.
14662 Don't use xrealloc. Improve diagnostics when the %l size modifier
14663 is used. Update the commentary.
14665 * eval.c (verror): Simplify calculation of size_t.
14667 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
14670 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
14672 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
14675 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14677 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
14678 This makes this file independent of the recent pseudovector change.
14680 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
14682 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
14684 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
14685 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
14686 Remove unused local.
14687 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
14689 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
14690 GCC 4.6.0 optimizes based on type-based alias analysis.
14691 For example, if b is of type struct buffer * and v of type struct
14692 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
14693 != &v->size, and therefore "v->size = 1; b->size = 2; return
14694 v->size;" must therefore return 1. This assumption is incorrect
14695 for Emacs, since it type-puns struct Lisp_Vector * with many other
14696 types. To fix this problem, this patch adds a new type struct
14697 vectorlike_header that documents the constraints on layout of vectors
14698 and pseudovectors, and helps optimizing compilers not get fooled
14699 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
14700 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
14701 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
14703 (XSETPVECTYPE): Rewrite in terms of new macro.
14704 (XSETPVECTYPESIZE): New macro, specifying both type and size.
14705 This is a bit clearer, and further avoids the possibility of
14706 undesirable aliasing.
14707 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
14708 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
14709 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
14710 since Lisp_Subr is a special case (no "next" field).
14711 (ASIZE): Now uses header.size rather than size.
14712 All previous uses of XVECTOR (foo)->size replaced to use this macro,
14713 to avoid the hassle of writing XVECTOR (foo)->header.size.
14714 (struct vectorlike_header): New type.
14715 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
14716 object, to help avoid aliasing.
14717 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
14718 (SUBRP): Likewise, since Lisp_Subr is a special case.
14719 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
14720 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
14721 (struct Lisp_Hash_Table): Combine first two members into a single
14722 struct vectorlike_header member. All uses of "size" and "next" members
14723 changed to be "header.size" and "header.next".
14724 * buffer.h (struct buffer): Likewise.
14725 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
14726 * frame.h (struct frame): Likewise.
14727 * process.h (struct Lisp_Process): Likewise.
14728 * termhooks.h (struct terminal): Likewise.
14729 * window.c (struct save_window_data, struct saved_window): Likewise.
14730 * window.h (struct window): Likewise.
14731 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
14732 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
14733 * buffer.c (init_buffer_once): Likewise.
14734 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
14736 * process.c (Fformat_network_address): Use local var for size,
14739 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
14741 Make the Lisp reader and string-to-float more consistent (Bug#8525)
14742 * data.c (atof): Remove decl; no longer used or needed.
14743 (digit_to_number): Move to lread.c.
14744 (Fstring_to_number): Use new string_to_number function, to be
14745 consistent with how the Lisp reader treats infinities and NaNs.
14746 Do not assume that floating-point numbers represent EMACS_INT
14747 without losing information; this is not true on most 64-bit hosts.
14748 Avoid double-rounding errors, by insisting on integers when
14749 parsing non-base-10 numbers, as the documentation specifies.
14750 * lisp.h (string_to_number): New decl, replacing ...
14751 (isfloat_string): Remove.
14752 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
14753 (read1): Do not accept +. and -. as integers; this
14754 appears to have been a coding error. Similarly, do not accept
14755 strings like +-1e0 as floating point numbers. Do not report
14756 overflow for integer overflows unless the base is not 10 which
14757 means we have no simple and reliable way to continue.
14758 Break out the floating-point parsing into a new
14759 function string_to_number, so that Fstring_to_number parses
14760 floating point numbers consistently with the Lisp reader.
14761 (digit_to_number): Move here from data.c. Make it static inline.
14762 (E_CHAR, EXP_INT): Remove, replacing with ...
14763 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
14764 (string_to_number): New function, replacing isfloat_string.
14765 This function checks for valid syntax and produces the resulting
14766 Lisp float number too. Rework it so that string-to-number
14767 no longer mishandles examples like "1.0e+". Use strtoumax,
14768 so that overflow for non-base-10 numbers is reported only when
14769 there's no portable and simple way to convert to floating point.
14771 * textprop.c (set_text_properties_1): Rewrite for clarity,
14772 and to avoid GCC warning about integer overflow.
14774 * intervals.h (struct interval): Use EMACS_INT for members
14775 where EMACS_UINT might cause problems. See
14776 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
14777 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
14778 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
14780 (offset_intervals): Tell GCC not to worry about length overflow
14781 when negating a negative length.
14783 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
14784 (overrun_check_free): Likewise.
14786 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
14787 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
14790 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14791 (gnutls_make_error): Rename local to avoid shadowing.
14792 (gnutls_emacs_global_deinit): ifdef out; not used.
14793 (Fgnutls_boot): Use const for pointer to readonly storage.
14794 Comment out unused local. Fix pointer signedness problems.
14796 * lread.c (openp): Don't stuff size_t into an 'int'.
14797 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
14798 about possible signed overflow.
14800 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14801 (GDK_KEY_g): Don't define if already defined.
14802 (xg_prepare_tooltip): Avoid pointer signedness problem.
14803 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
14805 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
14806 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
14808 * xfns.c (Fx_window_property): Simplify a bit,
14809 to make a bit faster and to avoid GCC 4.6.0 warning.
14810 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
14812 * fns.c (internal_equal): Don't assume size_t fits in int.
14814 * alloc.c (compact_small_strings): Tighten assertion a little.
14816 Replace pEd with more-general pI, and fix some printf arg casts.
14817 * lisp.h (pI): New macro, generalizing old pEd macro to other
14818 conversion specifiers. For example, use "...%"pI"d..." rather
14819 than "...%"pEd"...".
14820 (pEd): Remove. All uses replaced with similar uses of pI.
14821 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
14822 * alloc.c (check_pure_size): Don't overflow by converting size to int.
14823 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
14824 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
14825 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
14826 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
14827 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
14829 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
14830 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
14831 * print.c (safe_debug_print, print_object): Likewise.
14832 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
14834 Use pI instead of if-then-else-abort. Use %p to avoid casts,
14835 avoiding the 0 flag, which is not portable.
14836 * process.c (Fmake_network_process): Use pI to avoid cast.
14837 * region-cache.c (pp_cache): Likewise.
14838 * xdisp.c (decode_mode_spec): Likewise.
14839 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
14840 behavior on 64-bit hosts with printf arg.
14841 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
14842 (x_stop_queuing_selection_requests): Likewise.
14843 (x_get_window_property): Don't truncate byte count to an 'int'
14846 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
14847 here, since it parses constructs like leading '-' and spaces,
14848 which are not wanted; and it overflows with large numbers.
14849 Instead, simply match F[0-9]+, which is what is wanted anyway.
14851 * alloc.c: Remove unportable assumptions about struct layout.
14852 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
14853 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
14854 (allocate_vectorlike, make_pure_vector): Use the new macros,
14855 plus offsetof, to remove unportable assumptions about struct layout.
14856 These assumptions hold on all porting targets that I know of, but
14857 they are not guaranteed, they're easy to remove, and removing them
14858 makes further changes easier.
14860 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
14861 This doesn't fix a bug but makes the code clearer.
14862 (string_overrun_cookie): Now const. Use initializers that
14863 don't formally overflow signed char, to avoid warnings.
14864 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
14865 can cause Emacs to crash when string overrun checking is enabled.
14866 (allocate_buffer): Don't assume sizeof (struct buffer) is a
14867 multiple of sizeof (EMACS_INT); it need not be, if
14868 alignof(EMACS_INT) < sizeof (EMACS_INT).
14869 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
14871 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

14878 supposed to be handshaking. (Bug#8556)
14879 Reported by Paul Eggert <eggert@cs.ucla.edu>.

14898 2011-04-25 Eli Zaretskii <eliz@gnu.org>
14900 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
14901 "cast to pointer from integer of different size".
14903 Improve doprnt and its use in verror. (Bug#8545)
14904 * doprnt.c (doprnt): Document the set of format control sequences
14905 supported by the function. Use SAFE_ALLOCA instead of always
14908 * eval.c (verror): Don't limit the buffer size at size_max-1, that
14909 is one byte too soon. Don't use xrealloc; instead xfree and
14912 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
14914 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
14917 * gnutls.c: Renamed global_initialized to
14918 gnutls_global_initialized. Added internals for the
14919 :verify-hostname-error, :verify-error, and :verify-flags
14920 parameters of `gnutls-boot' and documented those parameters in the
14921 docstring. Start callback support.
14922 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
14923 unless a fatal error occurred. Call gnutls_alert_send_appropriate

14997 (SIZE_MAX): New macro.
14998 (doprnt): Return a size_t value. 2nd arg is now size_t.
14999 Many local variables are now size_t instead of int or unsigned.
15000 Improve overflow protection. Support `l' modifier for integer
15001 conversions. Support %l conversion. Don't assume an EMACS_INT
15002 argument for integer conversions and for %c.
15004 * lisp.h (doprnt): Restore prototype.
15006 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
15007 $(SRC)/character.h.
15009 * Makefile.in (base_obj): Add back doprnt.o.
15011 * deps.mk (doprnt.o): Add back prerequisites.

15021 * callint.c (Fcall_interactively): When displaying error message
15022 about invalid control letter, pass the character's codepoint, not
15023 a pointer to its multibyte form. Improve display of the character
15024 in octal and display also its hex code.
15026 * character.c (char_string): Use %x to display the (unsigned)
15027 codepoint of an invalid character, to avoid displaying a bogus
15030 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15031 `error', not SYMBOL_NAME itself.
15033 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

15036 * charset.c (check_iso_charset_parameter): Fix incorrect argument
15037 to `error' in error message about FINAL_CHAR argument. Make sure
15038 FINAL_CHAR is a character, and use %c when it is passed as

15109 * dispextern.h (struct redisplay_interface): Rename param
15110 to avoid shadowing.
15111 * termhooks.h (struct terminal): Likewise.

15115 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
15117 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
15120 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
15121 so that we aren't warned about unused symbols.

15138 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
15140 * xmenu.c (menu_help_callback): Pointer type fixes.

15158 compatible char. Avoid the old compiler warnings about
15159 out-of-range initializers by using, for example, '\xab' rather
15162 * xgselect.c (xgselect_initialize): Check vs interface
15163 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

15228 * nsfont.m: Fixed bugs in ns_get_family and
15229 ns_descriptor_to_entity that were caused by using free to
15230 deallocate memory blocks that were allocated by xmalloc (via
15231 xstrdup). This caused Emacs to crash when compiled with
15232 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
15233 --enable-checking=xmallocoverrun). xfree is now used to
15234 deallocate these memory blocks.

15640 Make Emacs functions such as Fatom 'static' by default.
15641 This makes it easier for human readers (and static analyzers)
15642 to see whether these functions can be called from other modules.
15643 DEFUN now defines a static function. To make the function external
15644 so that it can be used in other C modules, use the new macro DEFUE.
15645 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
15646 (Finit_image_library):
15647 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
15648 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
15649 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
15650 Remove decls, since these functions are now static.
15651 (Funintern, Fget_internal_run_time): New decls, since these functions
15652 were already external.
15654 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
15655 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
15656 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
15657 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
15658 * keyboard.c, keymap.c, lread.c:
15659 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
15660 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
15661 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
15662 Mark functions with DEFUE instead of DEFUN,
15663 if they are used in other modules.
15664 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
15665 decls for now-static functions.
15666 * buffer.h (Fdelete_overlay): Remove decl.
15667 * callproc.c (Fgetenv_internal): Mark as internal.
15668 * composite.c (Fremove_list_of_text_properties): Remove decl.
15669 (Fcomposition_get_gstring): New forward static decl.
15670 * composite.h (Fcomposite_get_gstring): Remove decl.
15671 * dired.c (Ffile_attributes): New forward static decl.
15672 * doc.c (Fdocumntation_property): New forward static decl.
15673 * eval.c (Ffetch_bytecode): New forward static decl.
15674 (Funintern): Remove extern decl; now in .h file where it belongs.
15675 * fileio.c (Fmake_symbolic_link): New forward static decl.
15676 * image.c (Finit_image_library): New forward static decl.
15677 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
15678 * intervals.h (Fprevious_property_change):
15679 (Fremove_list_of_text_properties): Remove decls.
15680 * keyboard.c (Fthis_command_keys): Remove decl.
15681 (Fcommand_execute): New forward static decl.
15682 * keymap.c (Flookup_key): New forward static decl.
15683 (Fcopy_keymap): Now static.
15684 * keymap.h (Flookup_key): Remove decl.
15685 * process.c (Fget_process): New forward static decl.
15686 (Fprocess_datagram_address): Mark as internal.
15687 * syntax.c (Fsyntax_table_p): New forward static decl.
15688 (skip_chars): Remove duplicate decl.
15689 * textprop.c (Fprevious_property_change): New forward static decl.
15690 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
15692 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
15693 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
15695 * editfns.c (Fformat): Remove unreachable code.
15697 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
15699 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
15702 2011-04-13 Eli Zaretskii <eliz@gnu.org>
15704 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
15705 when at ZV. (Bug#8487)
15707 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
15709 * charset.c (Fclear_charset_maps): Use xfree instead of free.
15711 * keyboard.c (parse_tool_bar_item): Likewise.
15712 * sound.c (sound_cleanup, alsa_close): Likewise.
15713 * termcap.c (tgetent): Likewise.
15714 * xfns.c (x_default_font_parameter): Likewise.
15715 * xsettings.c (read_and_apply_settings): Likewise.
15717 * alloc.c (overrun_check_malloc, overrun_check_realloc)
15718 (overrun_check_free): Protoize.
15720 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
15722 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
15723 since callers should never pass a negative size.
15724 Change the signature to match that of plain 'read' and 'write'; see
15725 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
15726 * lisp.h: Update prototypes of emacs_write and emacs_read.
15728 2011-04-11 Eli Zaretskii <eliz@gnu.org>
15730 * xdisp.c (redisplay_window): Don't try to determine the character
15731 position of the scroll margin if the window start point w->startp
15732 is outside the buffer's accessible region. (Bug#8468)
15734 2011-04-10 Eli Zaretskii <eliz@gnu.org>
15736 Fix write-region and its subroutines for buffers > 2GB.
15737 * fileio.c (a_write, e_write): Modify declaration of arguments and
15738 local variables to support buffers larger than 2GB.
15739 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
15741 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
15742 argument, local variables, and return value.
15744 * lisp.h: Update prototypes of emacs_write and emacs_read.
15746 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
15748 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
15750 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
15752 Fix more problems found by GCC 4.6.0's static checks.
15754 * xdisp.c (vmessage): Use a better test for character truncation.
15756 * charset.c (load_charset_map): <, not <=, for optimization,
15757 and to avoid potential problems with integer overflow.
15758 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
15759 * casetab.c (set_identity, shuffle): Likewise.
15760 * editfns.c (Fformat): Likewise.
15761 * syntax.c (skip_chars): Likewise.
15763 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
15764 This also lets GCC 4.6.0 generate slightly better loop code.
15766 * callint.c (Fcall_interactively): <, not <=, for optimization.
15767 (Fcall_interactively): Count the number of arguments produced,
15768 not the number of arguments given. This is simpler and lets GCC
15769 4.6.0 generate slightly better code.
15771 * ftfont.c: Distingish more carefully between FcChar8 and char.
15772 The previous code passed unsigned char * to a functions like
15773 strlen and xstrcasecmp that expect char *, which does not
15774 conform to the C standard.
15775 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
15776 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
15777 char * when the C standard requires it.
15779 * keyboard.c (read_char): Remove unused var.
15781 * eval.c: Port to Windows vsnprintf (Bug#8435).
15782 Include <limits.h>.
15783 (SIZE_MAX): Define if the headers do not.
15784 (verror): Do not give up if vsnprintf returns a negative count.
15785 Instead, grow the buffer. This ports to Windows vsnprintf, which
15786 does not conform to C99. Problem reported by Eli Zaretskii.
15787 Also, simplify the allocation scheme, by avoiding the need for
15788 calling realloc, and removing the ALLOCATED variable.
15790 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
15792 Remove invocations of doprnt, as Emacs now uses vsnprintf.
15793 But keep the doprint source code for now, as we might revamp it
15794 and use it again (Bug#8435).
15795 * lisp.h (doprnt): Remove.
15796 * Makefile.in (base_obj): Remove doprnt.o.
15797 * deps.mk (doprnt.o): Remove.
15799 error: Print 32- and 64-bit integers portably (Bug#8435).
15800 Without this change, on typical 64-bit hosts error ("...%d...", N)
15801 was used to print both 32- and 64-bit integers N, which relied on
15802 undefined behavior.
15803 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
15804 * lisp.h (error, verror): Mark as printf-like functions.
15805 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
15806 Report overflow in size calculations when allocating printf buffer.
15807 Do not truncate output string at its first null byte.
15808 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
15809 Truncate the output at a character boundary, since vsnprintf does not
15811 * charset.c (check_iso_charset_parameter): Convert internal
15812 character to string before calling 'error', since %c now has the
15814 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
15815 overflow when computing char to be passed to 'error'. Do not
15816 pass Lisp_Object to 'error'; pass the integer instead.
15817 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
15818 formatted with plain %d.
15820 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
15822 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
15824 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
15826 * xterm.c (x_catch_errors): Remove duplicate declaration.
15828 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
15830 * xdisp.c, lisp.h (message_nolog): Remove; unused.
15832 2011-04-10 Jim Meyering <meyering@redhat.com>
15834 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
15835 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
15836 return ssize_t not "int", and use size_t as the buffer length.
15837 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
15838 * gnutls.h: Update declarations.
15839 * process.c (read_process_output): Use ssize_t, to match.
15840 (send_process): Likewise.
15842 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15844 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
15846 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15848 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
15849 Use unsigned char, to match FcChar8 type definition.
15851 * xterm.c (handle_one_xevent):
15852 * xmenu.c (create_and_show_popup_menu):
15853 * xselect.c (x_decline_selection_request)
15854 (x_reply_selection_request): Avoid type-punned deref of X events.
15856 2011-04-09 Eli Zaretskii <eliz@gnu.org>
15858 Fix some uses of `int' instead of EMACS_INT.
15859 * search.c (string_match_1, fast_string_match)
15860 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
15861 (scan_buffer, find_next_newline_no_quit)
15862 (find_before_next_newline, search_command, Freplace_match)
15863 (Fmatch_data): Make some `int' variables be EMACS_INT.
15865 * xdisp.c (display_count_lines): 3rd argument and return value now
15866 EMACS_INT. All callers changed.
15867 (pint2hrstr): Last argument is now EMACS_INT.
15869 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
15870 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
15871 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
15872 (decode_coding_utf_16, decode_coding_emacs_mule)
15873 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
15874 (decode_coding_ccl, decode_coding_charset)
15875 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
15876 (decode_coding_iso_2022, decode_coding_emacs_mule)
15877 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
15878 <char_offset, last_offset>: Declare EMACS_INT.

15880 (encode_coding_emacs_mule, encode_invocation_designation)
15881 (encode_designation_at_bol, encode_coding_iso_2022)
15882 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
15883 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
15885 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
15886 (encode_invocation_designation): Last argument P_NCHARS is now
15888 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
15889 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
15891 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
15894 * ccl.c (Fccl_execute_on_string): Declare some variables
15897 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
15899 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
15901 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
15903 * process.c (Fformat_network_address): Doc fix.
15905 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
15907 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
15909 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
15911 * keyboard.c (read_char): Call Lisp function help-form-show,
15912 instead of using internal_with_output_to_temp_buffer.
15913 (Qhelp_form_show): New var.
15914 (syms_of_keyboard): Use DEFSYM macro.
15916 * print.c (internal_with_output_to_temp_buffer): Function deleted.
15918 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
15920 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
15922 * process.c (Flist_processes): Remove to Lisp.
15923 (list_processes_1): Delete.
15925 2011-04-06 Eli Zaretskii <eliz@gnu.org>
15927 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
15929 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
15931 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
15933 Fix more problems found by GCC 4.6.0's static checks.
15935 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
15937 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
15939 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
15941 * xdisp.c (vmessage): Mark as a printf-like function.
15943 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
15945 * sound.c (sound_warning): Don't crash if arg contains a printf format.
15947 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
15948 printf-like functions.
15949 (tiff_load): Add casts to remove these marks before passing them
15950 to system-supplied API.
15952 * eval.c (Fsignal): Remove excess argument to 'fatal'.
15954 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
15955 This avoids several warnings with gcc -Wstrict-overflow.
15956 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
15957 directly, rather than having caller test rule sign. This avoids
15958 some unnecessary tests.
15959 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
15960 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
15961 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
15963 * xfont.c (xfont_text_extents): Remove var that was set but not used.
15964 (xfont_open): Avoid unnecessary tests.
15966 * composite.c (composition_gstring_put_cache): Use unsigned integer.
15968 * composite.h, composite.c (composition_gstring_put_cache):
15969 Use EMACS_INT, not int, for length.

15972 breaking out part of COMPOSITION_DECODE_RULE.
15973 (COMPOSITION_DECODE_RULE): Use it.
15974 * composite.c (get_composition_id): Remove unused local vars,
15975 by using the new macro.
15977 * textprop.c (set_text_properties_1): Change while to do-while,
15978 since the condition is always true at first.
15980 * intervals.c (graft_intervals_into_buffer): Mark var as used.
15981 (interval_deletion_adjustment): Return unsigned value.
15984 * process.c (list_processes_1, create_pty, read_process_output):

15989 (read_process_output): Simplify nbytes computation if buffered.
15991 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
15993 * syntax.c (scan_words): Remove var that was set but not used.
15994 (update_syntax_table): Use unsigned instead of int.
15996 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
15997 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
15998 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
16000 * print.c (print_error_message): Avoid int overflow.
16002 * font.c (font_list_entities): Redo for clarity,
16003 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
16005 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
16006 (font_score): Avoid potential overflow in diff calculation.
16008 * fns.c (substring_both): Remove var that is set but not used.
16009 (sxhash): Redo loop for clarity and to avoid wraparound warning.
16011 * eval.c (funcall_lambda): Rename local to avoid shadowing.
16013 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
16014 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
16015 can always succeed if overflow has undefined behavior.
16017 * search.c (boyer_moore, wordify): Remove vars set but not used.
16018 (wordify): Omit three unnecessary tests.
16020 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
16021 All callers changed. This avoids the need for an unused var.
16023 * casefiddle.c (casify_region): Remove var that is set but not used.
16025 * dired.c (file_name_completion): Remove var that is set but not used.
16027 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
16029 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16030 (Finsert_file_contents): Remove unnecessary code checking fd.
16032 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
16033 Check for integer overflow on size calculations.
16035 * buffer.c (Fprevious_overlay_change): Remove var that is set
16038 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16039 Remove vars that are set but not used.
16040 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16041 (timer_check_2): Mark vars as initialized.
16043 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16045 * image.c (lookup_image): Remove var that is set but not used.
16046 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16048 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16049 that are set but not used.
16051 * xfns.c (make_invisible_cursor): Don't return garbage
16052 if XCreateBitmapFromData fails (Bug#8410).
16054 * xselect.c (x_get_local_selection, x_handle_property_notify):
16055 Remove vars that are set but not used.
16057 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
16058 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
16060 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
16061 Remove var that is set but not used.
16062 (scroll_bar_windows_size): Now size_t, not int.
16063 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16064 Check for overflow.
16066 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16067 (map_tty_color) [!defined MSDOS]: Likewise.
16069 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16071 * coding.c: Remove vars that are set but not used.
16072 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
16073 All callers changed.
16074 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
16075 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
16076 (decode_coding_charset): Remove vars that are set but not used.
16078 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
16079 that is set but not used.
16081 * print.c (print_object): Remove var that is set but not used.
16083 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16084 The gnulib version avoids calling malloc in the usual case,
16085 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16086 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16087 * filelock.c (current_lock_owner): Likewise.
16088 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16089 * sysdep.c: Include allocator.h, careadlinkat.h.
16090 (emacs_no_realloc_allocator): New static constant.
16091 (emacs_readlink): New function.
16092 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16093 ../lib/careadlinkat.h.
16095 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
16097 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

16119 do not dereference NULL upon failed strdup
16120 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16121 (ns_get_family): Likewise.
16123 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16125 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16127 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16129 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16132 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16134 Add lexical binding.
16136 * window.c (Ftemp_output_buffer_show): New fun.

16143 Bind Qinternal_interpreter_environment.
16144 (Feval_buffer): Bind Qlexical_binding.
16145 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16147 (syms_of_lread): Declare `lexical-binding'.
16149 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16151 * keyboard.c (eval_dyn): New fun.
16152 (menu_item_eval_property): Use it.
16154 * image.c (parse_image_spec): Use Ffunctionp.
16156 * fns.c (concat, mapcar1): Accept byte-code-functions.
16158 * eval.c (Fsetq): Handle lexical vars.
16159 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16160 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16161 (FletX, Flet): Obey lexical binding.
16162 (Fcommandp): Handle closures.
16163 (Feval): New `lexical' arg.
16164 (eval_sub): New function extracted from Feval. Use it almost
16165 everywhere where Feval was used. Look up vars in lexical env.
16167 (Ffunctionp): Move from subr.el.
16168 (Ffuncall): Handle closures.
16169 (apply_lambda): Remove `eval_flags'.
16170 (funcall_lambda): Handle closures and new byte-code-functions.
16171 (Fspecial_variable_p): New function.
16172 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16173 but without exporting it to Lisp.
16175 * doc.c (Fdocumentation, store_function_docstring):
16176 * data.c (Finteractive_form): Handle closures.
16178 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16181 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16183 (exec_byte_code): New function extracted from Fbyte_code to handle new
16184 calling convention for byte-code-functions. Add new byte-codes.
16186 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
16188 * alloc.c (Fmake_symbol): Init new `declared_special' field.
16190 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16192 * xdisp.c (redisplay_internal): Fix prototype.
16194 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16196 * xdisp.c (SCROLL_LIMIT): New macro.
16197 (try_scrolling): Use it when setting scroll_limit.
16198 Limit scrolling to 100 screen lines.
16199 (redisplay_window): Even when falling back on "recentering",
16200 position point in the window according to scroll-conservatively,
16201 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16203 (try_scrolling): When point is above the window, allow searching
16204 as far as scroll_max, or one screenful, to compute vertical
16205 distance from PT to the scroll margin position. This prevents
16206 try_scrolling from unnecessarily failing when
16207 scroll-conservatively is set to a value slightly larger than the
16208 window height. Clean up the case of PT below the margin at bottom
16209 of window: scroll_max can no longer be INT_MAX. When aggressive
16210 scrolling is in use, don't let point enter the opposite scroll
16211 margin as result of the scroll.
16212 (syms_of_xdisp) <scroll-conservatively>: Document the
16213 threshold of 100 lines for never-recentering scrolling.

16220 (message_log_check_duplicate): Remove parameters `prev_bol' and
16221 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16222 (redisplay_internal): Remove parameter `preserve_echo_area',
16223 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16225 * indent.c (Fvertical_motion):
16226 * window.c (window_scroll_pixel_based, Frecenter):
16227 Don't pass `need_y_p' to `move_it_by_lines'.
16229 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16231 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16232 steal a few bits to be more compact.
16233 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16234 Remove unneeded casts.
16236 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16238 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16240 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16241 binding" message (bug#7967).
16243 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16245 Fix more problems found by GCC 4.6.0's static checks.
16247 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16248 Remove unused local var.
16250 * editfns.c (Fmessage_box): Remove unused local var.
16252 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16253 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16254 Omit unused local vars.
16255 * window.c (shrink_windows): Omit unused local var.
16256 * menu.c (digest_single_submenu): Omit unused local var.
16257 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16258 Omit unused local var.
16260 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16261 Don't assume string length fits in int.
16262 (keyremap_step, read_key_sequence): Use size_t for sizes.

16265 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
16266 instead of alloca (Bug#8344).
16268 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16269 (Fbacktrace_frame): Don't assume nframes fits in int.
16271 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

16278 * cm.c (calccost): Turn while-do into do-while, for clarity.
16280 * keyboard.c (syms_of_keyboard): Use the same style as later
16281 in this function when indexing through an array. This also
16282 works around GCC bug 48267.
16284 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16286 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16288 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16289 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16291 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16292 This avoids undefined behavior on integer overflow, and is a bit
16293 more convenient anyway since it is compared to a size_t variable.
16295 Variadic C functions now count arguments with size_t, not int.
16296 This avoids an unnecessary limitation on 64-bit machines, which
16297 caused (substring ...) to crash on large vectors (Bug#8344).

16307 * fns.c (concat): Likewise.
16308 * frame.c (x_set_frame_parameters): Likewise.
16309 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16310 0 if not found, not -1. All callers changed.
16312 * alloc.c (garbage_collect): Don't assume stack size fits in int.
16313 (stack_copy_size): Now size_t, not int.
16314 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

16335 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
16336 don't set the hook to nil, but remove the offending function instead.
16337 (Qcommand_hook_internal): Remove, unused.
16338 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
16339 Vcommand_hook_internal.
16341 * eval.c (enum run_hooks_condition): Remove.
16342 (funcall_nil, funcall_not): New functions.
16343 (run_hook_with_args): Call each function through a `funcall' argument.

16518 * callint.c (Fcall_interactively):
16519 * buffer.c (Fkill_all_local_variables):
16520 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
16522 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
16523 unconditionally since it does the check itself.
16525 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
16527 Fix more problems found by GCC 4.5.2's static checks.
16529 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16530 the first time through the loop, since we know p0 < p1 then.
16531 This also avoids a gcc -Wstrict-overflow warning.
16533 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16534 leading to a memory leak, possible in functions like
16535 load_charset_map_from_file that can allocate an unbounded number
16536 of objects (Bug#8318).
16538 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16539 that could (at least in theory) be that large.
16541 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16542 This is less likely to overflow, and avoids undefined behavior if
16543 overflow does occur. All callers changed. Use strtoul to scan
16544 for the unsigned long integer.
16545 (pint2hrstr): Simplify and tune code slightly.
16546 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
16548 * scroll.c (do_scrolling): Work around GCC bug 48228.
16549 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
16551 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
16552 This also avoids a warning with gcc -Wstrict-overflow.
16553 (validate_x_resource_name): Simplify count usage.
16554 This also avoids a warning with gcc -Wstrict-overflow.
16556 * fileio.c (Fcopy_file): Report error if fchown or fchmod
16559 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
16561 * process.c (Fmake_network_process): Use socklen_t, not int,
16562 where POSIX says socklen_t is required in portable programs.
16563 This fixes a porting bug on hosts like 64-bit HP-UX, where
16564 socklen_t is wider than int (Bug#8277).
16565 (Fmake_network_process, server_accept_connection):
16566 (wait_reading_process_output, read_process_output):
16569 * process.c: Rename or move locals to avoid shadowing.

16579 Make tparam.h and terminfo.c consistent.
16580 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
16581 Include tparam.h instead, since it declares them.
16582 * cm.h (PC): Remove extern decl; tparam.h now does this.
16583 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
16584 * terminfo.c: Include tparam.h, to check interfaces.
16585 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
16586 (tparam): Adjust signature to match interface in tparam.h;
16587 this removes some undefined behavior. Check that outstring and len
16588 are zero, which they always are with Emacs.
16589 * tparam.h (PC, BC, UP): New extern decls.
16591 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
16592 (xftfont_open): Rename locals to avoid shadowing.
16594 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

16604 * xml.c (make_dom): Now static.
16606 * composite.c (composition_compute_stop_pos): Rename local to
16608 (composition_reseat_it): Remove unused locals.
16609 (find_automatic_composition, composition_adjust_point): Likewise.
16610 (composition_update_it): Mark var as initialized.
16611 (find_automatic_composition): Mark vars as initialized,
16612 with a FIXME (Bug#8290).

16615 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
16616 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
16617 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
16618 (BUF_DEC_POS): Be more systematic about renaming local temporaries
16619 to avoid shadowing.
16621 * textprop.c (property_change_between_p): Remove; unused.
16623 * intervals.c (interval_start_pos): Now static.
16625 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

16628 Rename locals to avoid shadowing.
16630 * sound.c (wav_play, au_play, Fplay_sound_internal):
16631 Fix pointer signedness.
16632 (alsa_choose_format): Remove unused local var.
16633 (wav_play): Initialize a variable to 0, to prevent undefined
16634 behavior (Bug#8278).
16636 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
16638 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
16640 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
16641 clobbering (Bug#8298).
16642 * sysdep.c (sys_subshell): Likewise.
16643 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
16645 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
16646 This should get cleaned up, so that child_setup has the
16647 same signature on all platforms.
16649 * callproc.c (call_process_cleanup): Now static.
16650 (relocate_fd): Rename locals to avoid shadowing.
16652 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
16654 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
16655 not to be necessary, and produces flickering.
16657 2011-03-20 Glenn Morris <rgm@gnu.org>
16659 * config.in: Remove file.
16661 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
16663 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
16664 are now in src/globals.h.
16665 (syms_of_minibuf): Remove spurious & from previous change.
16667 2011-03-20 Leo Liu <sdl.web@gmail.com>
16669 * minibuf.c (completing-read-function): New variable.
16670 (completing-read-default): Rename from completing-read.
16671 (completing-read): Call completing-read-function.
16673 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16675 * xfaces.c (Fx_load_color_file):
16676 Read color file from absolute filename (bug#8250).
16678 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16680 * makefile.w32-in: Update dependencies.
16682 2011-03-17 Eli Zaretskii <eliz@gnu.org>
16684 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

16691 (sigchld_handler): Now static.
16693 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
16694 That way, the code declares only the vars that it needs.
16695 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
16696 * s/cygwin.h (PTY_ITERATION): Likewise.
16697 * s/darwin.h (PTY_ITERATION): Likewise.

16704 (CONSTANTLIM): Remove; unused.
16705 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
16706 Define only if needed.
16708 * unexelf.c (unexec): Name an expression,
16709 to avoid gcc -Wbad-function-cast warning.
16710 Use a different way to cause a compilation error if anyone uses
16711 n rather than nn, a way that does not involve shadowing.
16712 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
16714 * deps.mk (unexalpha.o): Remove; unused.
16716 New file unexec.h, the (simple) interface for unexec (Bug#8267).
16717 * unexec.h: New file.
16718 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
16719 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
16720 Depend on unexec.h.
16721 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
16722 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
16723 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
16724 Change as necessary to match prototype in unexec.h.
16726 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

16743 (font_sort_entities): Mark var as initialized.
16745 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
16747 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

16771 * callint.c (quotify_arg, quotify_args): Now static.
16772 (Fcall_interactively): Rename locals to avoid shadowing.
16773 Use const pointer when appropriate.

16779 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
16780 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
16781 some of which prompt warnings from gcc -Wbad-function-cast.
16782 (Fformat_time_string, Fencode_time, Finsert_char):
16783 (Ftranslate_region_internal, Fformat):
16784 Rename or remove local vars to avoid shadowing.
16785 (Ftranslate_region_internal): Mark var as initialized.
16787 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
16790 * lisp.h (eassert): Check that the argument compiles, even if
16791 ENABLE_CHECKING is not defined.
16793 * data.c (Findirect_variable): Name an expression, to avoid
16794 gcc -Wbad-function-cast warning.
16795 (default_value, arithcompare, arith_driver, arith_error): Now static.

16802 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
16803 Rename locals to avoid shadowing.
16804 (mark_stack): Move local variables into the #ifdef region where
16806 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
16807 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
16809 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
16810 (GC_STRING_CHARS): Remove; not used.
16811 (Fmemory_limit): Cast sbrk's returned value to char *.
16813 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
16814 avoids undefined behavior in theory.
16816 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
16818 Use functions, not macros, for up- and down-casing (Bug#8254).
16819 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16820 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
16821 to use the following functions instead of these macros.
16822 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
16823 EMACS_INT, since callers assume the returned value fits in int.
16824 (upcase1): Likewise, for UPCASE_TABLE.
16825 (uppercasep, lowercasep, upcase): New static inline functions.
16826 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
16827 the race-condition problem in the old DOWNCASE.

16835 which gcc can warn about.
16836 (regex_compile, re_match_2_internal): Mark locals as initialized.
16837 (RETALLOC_IF): Define only if needed.
16838 (WORDCHAR_P): Likewise. This one is never needed, but is used
16839 only in a comment talking about a compiler bug, so put inside
16840 the #if 0 of that comment.
16841 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
16842 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
16845 * search.c (boyer_moore): Rename locals to avoid shadowing.
16846 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

16857 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
16859 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
16860 Rename locals to avoid shadowing.
16861 (Fvertical_motion): Mark locals as initialized.
16863 * casefiddle.c (casify_object, casify_region): Now static.
16864 (casify_region): Mark local as initialized.
16866 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
16868 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
16869 New macros, so that the caller can use some names other than
16870 gcpro1, gcpro2, etc.
16871 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
16873 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
16874 argument, for consistency with GCPRO2_VAR, etc: it is now the
16875 prefix of the variable, not the variable itself. All uses
16877 * dired.c (directory_files_internal, file_name_completion):
16878 Rename locals to avoid shadowing.
16880 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
16881 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
16882 dired.c's scmp function, had undefined behavior.
16883 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16884 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
16885 * buffer.h: ... to here, because these macros use current_buffer,
16886 and the new implementation with inline functions needs to have
16887 current_buffer in scope now, rather than later when the macros
16889 (downcase, upcase1): New static inline functions.
16890 (DOWNCASE, UPCASE1): Reimplement using these functions.
16891 This avoids undefined behavior in expressions like
16892 DOWNCASE (x) == DOWNCASE (y), which previously suffered
16893 from race conditions in accessing the global variables
16894 case_temp1 and case_temp2.
16895 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
16896 * lisp.h (case_temp1, case_temp2): Remove their decls.
16897 * character.h (ASCII_CHAR_P): Move from here ...
16898 * lisp.h: ... to here, so that the inline functions mentioned
16899 above can use them.
16901 * dired.c (directory_files_internal_unwind): Now static.
16903 * fileio.c (file_name_as_directory, directory_file_name):
16904 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
16906 (file_name_as_directory): Use const pointers when appropriate.
16907 (Fexpand_file_name): Likewise. In particular, newdir might
16908 point at constant storage, so make it a const pointer.
16909 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
16910 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
16912 (Fset_file_times, Finsert_file_contents, auto_save_error):
16913 Rename locals to avoid shadowing.
16915 * minibuf.c (choose_minibuf_frame_1): Now static.
16916 (Ftry_completion, Fall_completions): Rename or remove locals
16917 to avoid shadowing.
16919 * marker.c (bytepos_to_charpos): Remove; unused.
16921 * lisp.h (verify_bytepos, count_markers): New decls,
16922 so that gcc does not warn that these functions aren't declared.
16924 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
16925 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
16926 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
16927 (copy_text): Remove unused local var.
16929 * filelock.c (within_one_second): Now static.
16930 (lock_file_1): Rename local to avoid shadowing.
16932 * buffer.c (fix_overlays_before): Mark locals as initialized.
16933 (fix_start_end_in_overlays): Likewise. This function should be
16934 simplified by using pointers-to-pointers, but that's a different
16936 (switch_to_buffer_1): Now static.
16937 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
16938 (report_overlay_modification): Rename locals to avoid shadowing.
16940 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
16941 Fix pointer signedness issue.
16942 (sys_subshell): Mark local as volatile if checking for lint,
16943 to suppress a gcc -Wclobbered warning that does not seem to be right.
16944 (MAXPATHLEN): Define only if needed.
16946 * process.c (serial_open, serial_configure): Move decls from here ...
16947 * systty.h: ... to here, so that they can be checked.
16949 * fns.c (get_random, seed_random): Move extern decls from here ...
16950 * lisp.h: ... to here, so that they can be checked.
16952 * sysdep.c (reset_io): Now static.
16953 (wait_for_termination_signal): Remove; unused.
16955 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

16958 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
16959 (DENSE_TABLE_SIZE): Remove; unused.
16960 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
16961 (describe_map_tree):
16962 Rename locals to avoid shadowing.
16964 * keyboard.c: Declare functions static if they are not used elsewhere.
16965 (echo_char, echo_dash, cmd_error, top_level_2):
16966 (poll_for_input, handle_async_input): Now static.
