1 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4 (XParseGeometry): Now static. Substitute extremal values for
5 values that are out of range.
7 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
9 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
11 * nsfns.m (XParseGeometry): Remove.
12 (Fx_create_frame): Call x_set_offset to correctly interpret
15 * frame.c (read_integer, XParseGeometry): Moved from w32xfns.c.
16 (Fx_parse_geometry): If there is a space in string, call
17 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
19 2012-09-17 Eli Zaretskii <eliz@gnu.org>
21 * search.c (scan_buffer): Use character positions in calls to
22 region_cache_forward and region_cache_backward, not byte
23 positions. (Bug#12196)
25 * w32term.c (w32_read_socket): Set pending_signals to 1, like
26 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
28 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
29 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
30 emacs_blocked_malloc, now deleted.
32 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
34 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
35 The workaround was for improving performance on Solaris 2.4, but
36 is getting in the way now. Emacs will still work if someone is
37 still running Solaris 2.4 in a museum somewhere; Sun dropped
38 support for Solaris 2.4 in 2003.
39 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
40 * process.c (create_process) [HAVE_WORKING_VFORK]:
41 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
42 since Emacs no longer uses vfork on that platform.
44 2012-09-17 Glenn Morris <rgm@gnu.org>
46 * emacs.c: Use COPYRIGHT.
48 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
50 Remove configure's --without-sync-input option (Bug#12450).
51 When auditing signal-handling in preparation for cleaning it up,
52 I found that SYNC_INPUT has race conditions and would be a real
53 pain to fix. Since it's an undocumented and deprecated
54 configure-time option, now seems like a good time to remove it.
55 Also see <http://bugs.gnu.org/11080#16>.
56 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
57 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
58 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
60 (check_depth) [XMALLOC_OVERRUN_CHECK]:
61 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
62 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
63 (dont_register_blocks, bytes_used_when_reconsidered)
64 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
65 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
66 [!SYSTEM_MALLOC && !SYNC_INPUT]:
67 Remove. All uses removed.
68 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
69 implementation, one that depends on whether the new macro
70 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
72 * atimer.c (run_timers, handle_alarm_signal):
73 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
74 (handle_async_input, process_pending_signals)
75 (handle_input_available_signal, init_keyboard):
76 * nsterm.m (ns_read_socket):
77 * process.c (wait_reading_process_output):
78 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
79 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
81 * xterm.c (XTread_socket):
83 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
84 * eval.c (handling_signal): Remove. All uses removed.
85 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
86 All uses replaced with the SYNC_INPUT version.
87 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
89 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
92 * font.c (Ffont_shape_gstring): Remove unused local.
94 2012-09-16 Glenn Morris <rgm@gnu.org>
96 * Makefile.in (clean): No longer run nextstep's clean.
98 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
100 (ns-app): Move here from ns.mk, and simplify.
101 (clean): Simplify nextstep entry.
102 * ns.mk: Remove file.
104 2012-09-16 Kenichi Handa <handa@gnu.org>
106 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
107 not covert the last few charactes.
109 2012-09-16 Kenichi Handa <handa@gnu.org>
111 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
112 here, but just check the validity of glyphs in the glyph-string.
114 2012-09-16 Martin Rudalics <rudalics@gmx.at>
116 * window.c (Fwindow_parameter, Fset_window_parameter): Accept
117 any window as argument (Bug#12452).
119 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
121 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
122 to ns_term_init to avoid memory leak.
124 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
125 explicit retain/release.
126 (ns_term_init): Only allow one display. Initialize outerpool and
129 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
131 Port _setjmp fix to POSIXish hosts as well as Microsoft.
132 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
133 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
134 the Microsoft problem in a different way, by altering ../nt/config.nt.
136 2012-09-15 Eli Zaretskii <eliz@gnu.org>
151 * w16select.c: Remove inclusion of setjmp.h, as it is now included
152 by lisp.h. This completes removal of setjmp.h inclusion
153 erroneously announced in the previous commit. (Bug#12446)
155 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
158 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
159 not defined as a macro. The latter happens on MS-Windows.
162 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
164 Port better to POSIX hosts lacking _setjmp (Bug#12446).
165 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
166 Some instances of '#include <setjmp.h>' removed, if the
167 only reason for the instance was because "lisp.h" was included.
168 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
169 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
170 and _longjmp with the new symbols. Emacs already uses _setjmp if
171 available, so this change affects only POSIXish hosts that have
172 sigsetjmp but not _setjmp, such as some versions of Solaris and
173 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
174 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
175 (png_load_body) [HAVE_PNG]:
176 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
177 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
178 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
179 since PNG requires jmp_buf. This is the only exception to the
180 general rule that we now use sys_setjmp and sys_longjmp.
181 This exception is OK since this code does not change the signal
182 mask or longjmp out of a signal handler.
184 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
186 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
187 Include "syssignal.h", for 'main_thread'.
189 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
191 Avoid out-of-range marker position (Bug#12426).
192 * insdel.c (replace_range, replace_range_2): Adjust
193 markers before overlays, as suggested by comments.
194 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
195 Remove redundant check before calling offset_intervals.
197 2012-09-14 Martin Rudalics <rudalics@gmx.at>
199 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
200 current buffer (Bug#12387).
202 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
204 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
206 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
208 Use a more backwards-compatible timer format (Bug#12430).
209 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
210 vector element, not from the 4th, since PSECS is now at the end.
211 (Fcurrent_idle_time): Doc fix.
213 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
215 Function to mark objects and remove killed buffers at once.
216 * alloc.c (discard_killed_buffers): Rename to ...
217 (mark_discard_killed buffers) ... new name. Add marking
218 of remaining objects. Fix comment. Adjust users.
219 (mark_object): Do not touch frame buffer lists here.
220 * frame.c (delete_frame): Reset frame buffer lists here.
222 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
224 Better workaround for GNOME bug when --enable-gcc-warnings.
225 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
226 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
227 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
229 Simplify SIGIO usage (Bug#12408).
230 The code that dealt with SIGIO was crufty and confusing, e.g., it
231 played tricks like "#undef SIGIO" but these tricks were not used
232 consistently. Simplify mostly by not #undeffing standard symbols,
233 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
234 or not as we please) rather than "defined SIGIO" (standard symbol
235 that we probably shouldn't #undef).
236 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
237 Modules that need it can include it.
238 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
239 * dispextern.h (ignore_sigio): New decl.
240 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
241 unconditionally, since it's now a no-op if !USABLE_SIGIO.
242 * emacs.c (shut_down_emacs):
243 * keyboard.c (kbd_buffer_store_event_hold):
244 Use ignore_sigio rather than invoking 'signal' directly.
245 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
247 (FIONREAD, SIGIO): Do not #undef.
248 (tty_read_avail_input): Use #error rather than a syntax error.
249 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
250 for I_PIPE, used by SETUP_SLAVE_PTY.
251 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
252 * sysdep.c (croak): Remove; no longer needed. This bit of
253 temporary code, with Fred N. Fish's comment that it's temporary,
254 has been in Emacs since at least 1992!
255 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
256 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
257 * syssignal.h (croak): Remove decl.
258 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
259 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
260 now that we're termios-only.
261 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
262 * term.c (dissociate_if_controlling_tty): Use #error rather than
265 Work around GCC and GNOME bugs when --enable-gcc-warnings.
266 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
267 to work around GNOME bug 683906.
268 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
269 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
270 This works around GCC bug 54561.
272 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
274 More fixes for 'volatile' and setjmp/longjmp.
275 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
276 * image.c (struct png_load_context) [HAVE_PNG]: New type.
277 (png_load_body) [HAVE_PNG]:
278 (jpeg_load_body) [HAVE_JPEG]:
279 New function, with most of the old parent function's body.
280 (png_load) [HAVE_PNG]:
281 (jpeg_load) [HAVE_JPEG]:
282 Invoke the new function, to avoid longjmp munging our locals.
283 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
284 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
285 longjmp is passed 2, as the C standard doesn't guarantee this.
286 Instead, store the failure code into mgr->failure_code.
288 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
290 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
291 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
292 (syms_of_keyboard): Remove support for unread-command-char.
294 2012-09-12 Eli Zaretskii <eliz@gnu.org>
296 * w32proc.c (sys_kill): If PID is our process ID and the signal is
297 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
298 violation. (Bug#12426)
300 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
302 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
304 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
306 * eval.c: Add `inhibit-debugger'.
307 (Qinhibit_debugger): New symbol.
308 (call_debugger): Bind it instead of Qdebug_on_error.
309 (maybe_call_debugger): Test Vinhibit_debugger.
310 (syms_of_eval): Define inhibit-debugger.
311 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
312 (syms_of_xdisp): Remove inhibit-debug-on-message.
314 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
316 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
317 If a nonvolatile local variable is written before a _longjmp to
318 the frame containing the variable, and is read after the _longjmp,
319 the value read is indeterminate. Some local variables of type
320 'struct handler' and 'struct catchtag' are used in this way, so
321 mark each of their slots as volatile if the slot can be set before
322 _longjmp and read afterwards.
323 * lisp.h (struct handler): var and chosen_clause are now volatile.
324 (struct catchtag): val, next, and pdlcount are now volatile.
326 * bidi.c (bidi_push_it, bidi_pop_it):
327 * fns.c (copy_hash_table):
328 * image.c (define_image_type):
329 * keyboard.c (kbd_buffer_store_event_hold):
330 * process.c (Fprocess_send_eof):
331 * xfaces.c (x_create_gc) [HAVE_NS]:
332 * xgselect.c (xg_select):
333 Prefer assignment to memcpy when either will do.
335 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
336 Use pointer-to-a-pointer to simplify and avoid a NILP check each
337 time an item is removed. No need to mark this function 'inline';
338 the compiler knows better than we do.
340 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
342 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
343 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
344 to change_frame_size (Bug#12388).
345 (windowDidResize:): Pass YES to updateFrameSize.
347 * nsterm.h: Add delay parameter to updateFrameSize.
349 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
351 Discard killed buffers from deleted window and frame objects.
352 This reduces an amount of references to killed buffers and
353 helps GC to reclaim them faster.
354 * alloc.c (discard_killed_buffers): New function.
355 (mark_object): Use it for deleted windows and frames.
356 (mark_object): If symbol's value is set up for a killed buffer
357 or deleted frame, restore it's global binding.
358 * data.c (swap_in_global_binding): Add GC notice.
359 (swap_in_symval_forwarding): Use convenient set_blv_where.
360 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
361 * window.h: ... to here.
363 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
365 Convenient macro to check whether the buffer is live.
366 * buffer.h (BUFFER_LIVE_P): New macro.
367 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
368 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
370 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
372 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
373 composition cases (Bug#12364).
375 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
376 overhang of succeeding glyphs overlapping box cursor.
378 * w32term.c (x_draw_glyph_string): Likewise.
380 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
382 Simplify, document, and port floating-point (Bug#12381).
383 The porting part of this patch fixes bugs on non-IEEE platforms
384 with frexp, ldexp, logb.
385 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
387 * floatfns.c: Simplify discussion of functions that Emacs doesn't
388 support, by removing commented-out code and briefly listing the
389 C89 functions excluded. The commented-out stuff was confusing
390 maintenance, e.g., we thought we needed cbrt but it was commented out.
391 (logb): Remove decl; no longer needed.
392 (isfinite): New macro, if not already supplied.
393 (isnan): Don't replace any existing macro.
394 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
395 are present on all C89 platforms.
396 (Ffrexp): Do not special-case zero, as frexp does the right thing
398 (Flogb): Do not use logb, as it doesn't have the desired meaning
399 on hosts that use non-base-2 floating point. Instead, stick with
400 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
401 frexp, to avoid getting an unspecified result.
403 * xdisp.c (Qinhibit_debug_on_message): Now static.
405 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
407 * nsterm.m (ns_update_begin): Set clip path to whole view by using
408 NSBezierPath (Bug#12131).
410 2012-09-10 Chong Yidong <cyd@gnu.org>
412 * fns.c (Fdelq, Fdelete): Doc fix.
414 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
416 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
417 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
419 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
421 * lisp.h (make_lisp_ptr): New macro to replace XSET.
422 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
425 2012-09-09 Eli Zaretskii <eliz@gnu.org>
427 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
428 left fringe if the window has a left margin. This avoids leaving
429 traces of the cursor because its leftmost pixel is not drawn over.
431 * dispnew.c (update_window_line): When the left margin area of a
432 screen line is updated, set the redraw_fringe_bitmaps_p flag of
433 that screen line. (Bug#12277)
435 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
437 Assume C89 or later for math functions (Bug#12381).
438 This simplifies the code, and makes it a bit smaller and faster,
439 and (most important) makes it easier to clean up signal handling
440 since we can stop worring about floating-point exceptions in
441 library code. That was a problem before C89, but the problem
442 went away many years ago on all practical Emacs targets.
443 * data.c, image.c, lread.c, print.c:
444 Don't include <math.h>; no longer needed.
445 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
446 might be autoconfigured, as that never happens.
448 * doprnt.c (DBL_MAX_10_EXP):
450 Remove. C89 or later always defines these.
451 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
452 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
453 (arith_error, domain_error, domain_error2):
454 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
455 no longer needed -- we simply return what C returns. All uses removed.
456 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
458 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
459 Remove. All uses expanded, as these macros are no longer used
460 more than once and are now more trouble than they're worth.
461 (Ftan): Use tan, not sin / cos.
462 (Flogb): Assume C89 frexp.
463 (fmod_float): Assume C89 fmod.
464 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
465 (init_floatfns): Remove. All uses removed.
467 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
469 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
470 compositeToPoint for OSX < 10.6 (Bug#12390).
472 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
474 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
475 This produces more-accurate results.
477 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
479 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
482 2012-09-08 Chong Yidong <cyd@gnu.org>
484 * syntax.c (Fstring_to_syntax): Doc fix.
486 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
488 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
489 in the internal border.
490 (x_set_window_size): Remove static variables and their usage.
491 (ns_redraw_scroll_bars): Fix NSTRACE arg.
492 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
493 fringe/internal border adjustment (Bug#11052).
494 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
495 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
496 (ns_fix_rect_ibw): Remove.
497 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
498 (ns_dumpglyphs_box_or_relief): Ditto.
499 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
501 (ns_dumpglyphs_image): Ditto.
502 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
504 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
505 their usage. Add fringe_extended_p and its use as in other terms.
506 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
507 scroll bar was removed.
508 (updateFrameSize): New function.
509 (windowDidResize): Move code to updateFrameSize and call it.
511 * nsterm.h (EmacsView): Add updateFrameSize.
513 2012-09-07 Chong Yidong <cyd@gnu.org>
515 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
517 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
519 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
521 More signal-handler cleanup (Bug#12327).
522 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
523 Problem introduced when merging patches. Noted by Eli Zaretskii in
524 <http://bugs.gnu.org/12327#67>.
525 * floatfns.c: Comment fix.
526 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
527 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
528 and anyway the declaration is harmless even if SIGDANGER is not defined.
529 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
530 defined BROKEN_FIONREAD). systty.h formerly did this, but other
531 source files not surprisingly expected syssignal.h to define, or
532 not define, SIGIO, and it's cleaner to do it that way, for consistency.
533 Include <sys/ioctl.h>, for FIONREAD.
534 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
535 This eliminates a problem whereby other files mysteriously had
536 to include "syssignal.h" before including "systty.h" if they
537 wanted to use "#ifdef SIGIO".
539 2012-09-07 Eli Zaretskii <eliz@gnu.org>
541 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
543 * w32.c (sigemptyset): Empty the set.
544 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
546 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
548 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
550 * alloc.c (mark_buffer): Revert unsafe marking optimization.
551 (mark_object): Likewise for frame objects.
553 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
555 * syssignal.h (handle_on_main_thread): Always declare,
556 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
557 This ports to platforms without HAVE_PTHREAD.
559 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
561 Signal-handler cleanup (Bug#12327).
562 Emacs's signal handlers were written in the old 4.2BSD style with
563 sigblock and sigmask and so forth, and this led to some
564 inefficiencies and confusion. Rewrite these to use
565 pthread_sigmask etc. without copying signal sets around. Also,
566 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
567 'signal', and instead use functions that do not attempt to take
568 over the system name space. This patch causes Emacs's text
569 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
570 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
571 Do not include <signal.h> or "syssignal.h", as these
572 modules do not use signals.
573 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
574 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
575 Do not include <signal.h>, as "syssignal.h" does that for us now.
576 * atimer.c (sigmask_atimers): New function.
577 (block_atimers, unblock_atimers): New functions,
578 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
580 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
581 no longer needed here.
582 * emacs.c (main): Inspect existing signal handler with sigaction,
583 so that there's no need to block and unblock SIGHUP.
584 * sysdep.c (struct save_signal): New member 'action', replacing
585 old member 'handler'.
586 (save_signal_handlers, restore_signal_handlers):
587 Use sigaction instead of 'signal' to save and restore.
588 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
589 New function. All users of 'signal' modified to use set_sighandler
590 if they're writeonly, and to use sys_signal if they're read+write.
591 (emacs_sigaction_init, forwarded_signal): New functions.
592 (sys_signal): Remove. All uses replaced by calls to sigaction
593 and emacs_sigaction_init, or by direct calls to 'signal'.
594 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
595 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
596 all uses replaced by pthread_sigmask etc. calls.
597 * syssignal.h: Include <signal.h>.
598 (emacs_sigaction_init, forwarded_signal): New decls.
599 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
600 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
601 (sigmask, sys_sigmask): Remove; no longer needed.
602 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
603 (sigblock, sigunblock, sigfree):
604 (sigsetmask) [!defined sigsetmask]:
605 Remove. All uses replaced by pthread_sigmask.
606 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
607 no longer need to be replaced, and its typical old uses
608 are now done via emacs_sigaction_init and sigaction.
609 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
610 (sys_sigdel): Remove; unused.
611 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
613 2012-09-06 Eli Zaretskii <eliz@gnu.org>
615 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
616 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
618 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
620 Explicitly mark buffer_defaults and buffer_local_symbols.
621 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
622 mark_local_symbols here.
623 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
624 since special buffers aren't marked here any more.
625 (allocate_buffer): Chain new buffer with all_buffers here...
626 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
628 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
629 (syms_of_buffer): Remove staticpro of the above.
630 (init_buffer_once): Set names for buffer_defaults and
631 buffer_local_symbols.
633 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
635 Use bool for booleans in font-related modules.
636 * font.c (font_intern_prop, font_style_to_value)
637 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
638 (generate_otf_features, font_check_otf_features, font_check_otf)
639 (font_match_p, font_list_entities, font_at):
640 * fontset.c (fontset_id_valid_p, reorder_font_vector
641 (fontset_find_font, Fset_fontset_font)
642 (face_suitable_for_char_p) [0]:
643 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
644 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
645 (m17n_flt_initialized, ftfont_shape_by_flt):
646 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
647 * nsfont.m (nsfont_draw):
648 * w32font.c (w32font_draw):
649 * w32term.c (x_draw_glyphless_glyph_string_foreground):
650 Use bool for booleans.
651 * font.h: Adjust to above API changes.
652 (struct font, struct font_driver, struct font_driver_list):
653 Use bool for booleans.
654 (struct font): Remove useless member encoding_type.
656 * fontset.c, xftfont.c: Omit unnecessary static decls.
658 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
660 * alloc.c (mark_object): Revert window marking code
661 since it's unsafe for the Fset_window_configuration.
663 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
665 Fix race conditions with signal handlers and errno (Bug#12327).
666 Be more systematic about preserving errno whenever a signal
667 handler returns, even if it's not in the main thread. Do this by
668 renaming signal handlers to distinguish between signal delivery
669 and signal handling. All uses changed.
670 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
671 * data.c (deliver_arith_signal): Rename from arith_error.
672 * dispnew.c (deliver_window_change_signal): Rename from
673 window_change_signal.
674 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
675 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
676 * keyboard.c (deliver_input_available_signal): Rename from
677 input_available_signal.
678 (deliver_user_signal): Rename from handle_user_signal.
679 (deliver_interrupt_signal): Rename from interrupt_signal.
680 * process.c (deliver_pipe_signal): Rename from send_process_trap.
681 (deliver_child_signal): Rename from sigchld_handler.
682 * atimer.c (handle_alarm_signal):
683 * data.c (handle_arith_signal):
684 * dispnew.c (handle_window_change_signal):
685 * emacs.c (handle_fatal_signal, handle_danger_signal):
686 * keyboard.c (handle_input_available_signal):
687 * keyboard.c (handle_user_signal, handle_interrupt_signal):
688 * process.c (handle_pipe_signal, handle_child_signal):
689 New functions, with the actual signal-handling code taken from the
690 original respective signal handlers, sans the sporadic attempts to
691 preserve errno, since that's now done by handle_on_main_thread.
692 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
693 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
694 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
696 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
697 Move initialization of main_thread to sysdep.c's init_signals.
698 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
699 our usage, and simplifies the mainline code.
700 (record_child_status_change): New static function, as a helper
701 for handle_child_signal, and with most of the old child handler's
703 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
704 (handle_child_signal): Use the above.
705 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
706 Moved here from emacs.c.
707 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
708 code moved here from emacs.c's main function.
709 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
710 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
711 lets callers save and restore errno properly.
713 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
715 Remove redundant or unused things here and there.
716 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
717 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
718 * editfns.c (Fcompare_buffer_substrings): Likewise.
719 * frame.h (struct terminal, struct font_driver_list):
720 Remove redundant declarations.
721 * window.h (Qleft, Qright): Likewise.
723 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
725 Do not mark objects from deleted buffers, windows and frames.
726 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
727 (mark_object): Likewise for windows and frames.
729 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
731 * alloc.c (valid_lisp_object_p): Treat killed buffers,
732 buffer_defaults and buffer_local_symbols as valid objects.
733 Return special value to denote them.
735 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
737 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
738 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
739 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
740 (file_name_absolute_p, Fsubstitute_in_file_name):
741 (check_executable, check_writable, Ffile_accessible_directory_p)
742 (Fset_file_selinux_context, Fdefault_file_modes)
743 (Finsert_file_contents, choose_write_coding_system)
744 (Fwrite_region, build_annotations, a_write, e_write)
746 * filelock.c (boot_time_initialized, get_boot_time)
747 (get_boot_time_1, lock_file_1, within_one_second):
748 * floatfns.c (in_float):
749 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
750 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
751 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
752 * lisp.h (struct Lisp_Hash_Table.cmpfn):
753 * window.c (compare_window_configurations):
754 Use bool for booleans.
755 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
756 (Fdefault_file_modes): Now mode_t, not int, for modes.
757 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
758 (internal_delete_file): Now returns void, not a (boolean) int,
759 since nobody was looking at the return value.
760 * lisp.h, window.h: Adjust to above API changes.
762 * xdisp.c (set_message): Simplify and reindent last change.
764 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
766 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
768 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
770 * eval.c (call_debugger): Make the function non-static so that we
771 can call it from set_message.
773 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
774 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
776 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
778 Give more-useful info on a fatal error (Bug#12328).
779 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
780 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
781 of doing the work ourselves.
782 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
784 (fatal_error_backtrace): New function, taken from the guts
785 of the old fatal_error_signal, but with a new option to output
787 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
788 info about the signal than just its number.
789 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
790 * sysdep.c: Include <execinfo.h>
791 (emacs_backtrace): New function, taken partly from the previous
792 code of the 'die' function.
793 (emacs_abort): Call fatal_error_backtrace rather than abort.
795 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
797 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
798 eager (load-time) macro-expansion.
799 * lisp.mk (lisp): Add macroexp.
801 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
803 Simplify redefinition of 'abort' (Bug#12316).
804 Do not try to redefine the 'abort' function. Instead, redo
805 the code so that it calls 'emacs_abort' rather than 'abort'.
806 This removes the need for the NO_ABORT configure-time macro
807 and makes it easier to change the abort code to do a backtrace.
808 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
809 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
810 Remove; sysdep.c's emacs_abort now takes its place.
811 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
812 'abort' changed to use 'emacs_abort'.
813 * msdos.c (dos_abort) [defined abort]: Remove; not used.
814 (abort) [!defined abort]: Rename to ...
815 (emacs_abort): ... new name.
816 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
817 the place of the old 'abort' in emacs.c.
818 * w32.c, w32fns.c (abort): Do not #undef.
819 * w32.c (emacs_abort): Rename from w32_abort.
821 2012-09-04 Eli Zaretskii <eliz@gnu.org>
823 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
824 offsets[j].dv, since the y axis of the screen coordinates points
825 down, while the y axis of the font definition coordinates points
826 up. This fixes display of Arabic diacritics such as KASRA and
827 KASRATAN. (Bug#11860)
829 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
831 Be more systematic about _setjmp vs setjmp.
832 * alloc.c (test_setjmp, mark_stack):
833 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
834 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
835 (png_load, my_error_exit, jpeg_load):
836 * process.c (send_process_trap, send_process):
837 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
838 The underscored versions are up to 30x faster on some hosts.
839 Formerly, the code used setjmp+longjmp sometimes and
840 _setjmp+_longjmp at other times, with no particular reason to
841 prefer setjmp+longjmp.
843 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
845 Fix minor problem found by static checking.
846 * buffer.c (Fdelete_all_overlays): Return nil.
848 2012-09-03 Martin Rudalics <rudalics@gmx.at>
850 * buffer.c (Fdelete_all_overlays): New function.
852 2012-09-03 Chong Yidong <cyd@gnu.org>
854 * gtkutil.c: Add extern decl for Qxft.
856 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
858 * emacs.c, eval.c: Use bool for boolean.
859 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
860 (malloc_using_checking) [DOUG_LEA_MALLOC]:
861 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
862 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
863 (main, decode_env_path, Fdaemon_initialized):
864 * eval.c (call_debugger, Finteractive_p, interactive_p):
865 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
866 (maybe_call_debugger, Fbacktrace):
867 * process.c (read_process_output, exec_sentinel):
868 Use bool for booleans.
869 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
871 * eval.c (interactive_p): Omit always-true boolean argument
872 EXCLUDE_SUBRS_P. All callers changed.
873 * dispextern.h, lisp.h: Reflect above API changes.
874 * firstfile.c (dummy): Use the address of 'main', whose signature
875 won't change, instead of the address of 'initialize', whose
876 signature just changed from int to bool.
877 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
878 * msdos.c (fatal_error_in_progress): ... from here.
879 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
881 (redisplay_internal, unwind_redisplay): Simply clear
882 REDISPLAYING_P when unwinding, instead of saving its previous,
883 always-false value and then restoring it.
885 Clean up some extern decls.
886 Mostly, this hoists extern decls out of .c files and into .h files.
887 That way, we're more likely to catch errors if the interfaces change.
888 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
889 declare xg_mark_data.
890 * dispextern.h (x_frame_parm_handlers):
892 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
893 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
894 (Qultra_bold, Qoblique, Qitalic):
895 Move extern decl here from .c file.
896 * alloc.c (xg_mark_data) [USE_GTK]:
898 * eval.c (Qlexical_binding):
899 * fns.c (time) [!HAVE_UNISTD_H]:
900 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
901 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
902 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
903 * lread.c (Qinternal_interpreter_environment):
904 * minibuf.c (Qbuffer):
905 * process.c (QCfamily, QCfilter):
906 * widget.c (free_frame_faces):
907 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
908 * xfont.c (x_clear_errors):
909 * xterm.c (x_frame_parm_handlers):
910 Remove now-redundant extern decls.
911 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
912 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
914 * xfaces.c: Remove unnecessary static decls.
915 * xterm.c (updating_frame): Remove decl of nonexistent object.
917 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
918 when building globals.h, as the objects that are not built on
919 this host are not needed to compile C files on this host.
921 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
923 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

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

1040 x_set_window_size, x_sync, x_get_focus_frame,
1041 x_set_mouse_position, x_set_mouse_pixel_position,
1042 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

1099 for GCC 4.7.1 x86-64.
1101 2012-08-30 Glenn Morris <rgm@gnu.org>
1103 * lread.c (init_lread): For out-of-tree builds, only add the
1104 source directory's site-lisp dir to the load-path if it exists,
1105 consistent with in-tree builds. (Bug#12302)
1107 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

1135 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
1136 is not one of the heaps we manage. (Bug#12242)
1138 2012-08-28 Glenn Morris <rgm@gnu.org>

1340 * lisp.h (ASET): Remove attempt to detect side effects.
1341 It was meant to be temporary and it often doesn't work,
1342 because when IDX has side effects the behavior of IDX==IDX
1343 is undefined. See Stefan Monnier in
1344 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
1346 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

1355 as that's faster and simpler than static storage. Don't bother
1356 with the g_main_context_query overhead if g_main_context_pending
1357 says no events are pending.
1358 (gfds, gfds_size): Remove these static vars.
1359 (xgselect_initialize): Remove; no longer needed.
1360 All uses and decls removed.

1380 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1381 * Makefile.in (LIB_EXECINFO): New macro.
1384 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1385 * bytecode.c (exec_byte_code):
1386 * callint.c (check_mark, Fcall_interactively):
1387 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1388 (getenv_internal, sync_process_alive, call_process_exited):
1389 * lisp.h (USE_SAFE_ALLOCA):
1390 Use bool for booleans, instead of int.
1391 * lisp.h, process.h: Adjust prototypes to match above changes.
1392 * callint.c (Fcall_interactively): Don't assume the mark's
1393 offset fits in 'int'.
1395 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1397 * buffer.c, buffer.h: Use bool for boolean.
1398 * buffer.c (reset_buffer_local_variables)
1399 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1400 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
1401 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
1402 (overlay_touches_p, overlay_strings, Foverlay_put)
1403 (report_overlay_modification, call_overlay_mod_hooks):
1404 (mmap_enlarge, mmap_set_vars):
1405 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1406 Use bool for booleans, instead of int.
1407 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1408 since the 1-or-0 return value is always ignored anyway.
1409 (mmap_initialized_p):
1410 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1411 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1413 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1415 * bidi.c: Use bool for boolean.
1416 This is a bit more readable, and makes the text segment of bidi.o
1417 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1418 Presumably it's faster too.
1419 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1421 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1422 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1423 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1424 (bidi_explicit_dir_char, bidi_level_of_next_char)
1425 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1426 Use bool for booleans, instead of int.
1427 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1428 (bidi_unshelve_cache): Adjust decls to match code.
1430 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1432 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1435 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1437 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1438 * atimer.h: Include <stdbool.h>.
1440 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1442 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1443 compile time tests instead of run time tests on systems that do
1445 (FRAME_MAC_P): Remove leftover from deleted code.
1446 * frame.c (syms_of_frame): Remove leftover from deleted code.
1448 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>

1452 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1454 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1455 Otherwise, the compiler complains about (A?B:C) where B is void
1456 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1457 (fontset_add): Return void, for FONTSET_ADD.
1459 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1461 * alloc.c: Use bool for booleans.
1462 (gc_in_progress, abort_on_gc)
1463 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1464 (dont_register_blocks) [GC_MALLOC_CHECK]:
1465 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1466 (check_string_bytes, make_specified_string, memory_full)
1467 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1468 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1469 (mark_stack, valid_pointer_p, make_pure_string)
1470 (Fgarbage_collect, survives_gc_p, gc_sweep):
1471 Use bool for booleans, instead of int.
1472 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1473 Remove unused local.
1474 * alloc.c (PURE_POINTER_P):
1475 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1476 * editfns.c (Fformat):
1477 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1479 * fns.c (sweep_weak_table):
1480 * lisp.h (suppress_checking, push_message, survives_gc_p)
1481 (make_pure_string, gc_in_progress, abort_on_gc):
1482 * lread.c (readchar, read1):
1483 * print.c (Fprin1_to_string):
1484 * xdisp.c (push_message):
1485 Use bool for booleans affected directly or indirectly by
1488 Make recently-introduced setters macros.
1489 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1490 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1491 (set_fontset_default, set_fontset_fallback): Rename from their
1492 upper-case counterparts, and make them functions rather than macros.
1493 This is more consistent with the other recently-introduced setters.
1494 These don't need to be inline, since they're local.
1496 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1498 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1499 the loop (Bug#12247).
1501 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1503 * lisp.h (vcopy): Use memcpy rather than our own loop.
1504 This fixes a performance regression introduced by the recent
1505 addition of vcopy. This means 'vcopy' will need to be modified
1506 for a copying collector, but that's OK. Also, tighten the
1507 checking in the assertion.
1509 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1511 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1512 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1513 non-base glyph for the width of the base character, according to
1514 what x_draw_composite_glyph_string_foreground expects.
1515 Generate WADJUST value according to composition_gstring_width's
1516 expectations, to produce correct width of the composed character.
1517 Reverse the sign of the DU offset produced by ScriptPlace.
1519 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1521 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1523 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1525 Avoid direct writes to contents member of struct Lisp_Vector.
1526 * lisp.h (vcopy): New function to copy data into vector.
1527 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
1528 * fns.c (Ffillarray): Use ASET.
1529 * keyboard.c (timer_check_2): Use AREF and ASET.
1530 (append_tool_bar_item, Frecent_keys): Use vcopy.
1531 * lread.c (read_vector): Use ASET.
1532 * msdos.c (Frecent_doskeys): Use vcopy.

1540 the position of its buffer's point.
1541 (Fset_window_point): For the selected window always go in its
1542 buffer to the specified position.
1544 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1546 Setter macros for fontsets.
1547 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1548 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1549 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1552 2012-08-20 Glenn Morris <rgm@gnu.org>
1554 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1555 Don't assume that `ln -f' works.
1557 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1559 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1560 and later about non-assignments with no effect. See discussion at
1561 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1564 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1566 Inline setter functions for Lisp_Objects slots of struct specbinding.
1567 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
1570 2012-08-20 Martin Rudalics <rudalics@gmx.at>
1572 * window.c (select_window): Always make selected window's buffer
1575 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1577 Use AREF and ASET for docstrings of category tables.
1578 * category.h (CATEGORY_DOCSTRING): Use AREF.
1579 (SET_CATEGORY_DOCSTRING): Use ASET.
1580 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
1582 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1584 Inline setter functions for hash table members.
1585 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
1586 (set_hash_hash, set_hash_index): Rename with _slot suffix.
1587 (set_hash_key_and_value, set_hash_index, set_hash_next)
1588 (set_hash_hash): New functions.
1589 * charset.c, fns.c: Adjust users.
1591 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1593 Inline getter and setter functions for per-buffer values.
1594 * buffer.h (per_buffer_default, set_per_buffer_default)
1595 (per_buffer_value, set_per_buffer_value): New functions.
1596 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
1597 * buffer.c, data.c: Adjust users.
1599 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
1601 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
1603 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
1605 Rely on <config.h> + <unistd.h> to declare 'environ',
1606 as gnulib does this if the system doesn't.
1607 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
1608 Remove declaration. MS-Windows declares it on stdlib.h which is
1609 included by conf_post.h.
1610 * emacs.c (environ) [DOUG_LEA_MALLOC]:
1611 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
1612 * vm-limit.c: Include <unistd.h>, for 'environ'.
1614 * unexaix.c, unexcoff.c: Include "mem-limits.h".
1615 (start_of_data): Remove decl; mem-limits.h provides it.
1617 * xdisp.c (handle_invisible_prop): Make it a bit faster
1618 and avoid a gcc -Wmaybe-uninitialized diagnostic.
1620 2012-08-19 Chong Yidong <cyd@gnu.org>
1622 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
1625 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
1627 * .gdbinit: Use call instead of set when calling a function in the
1630 * data.c (set_internal): Don't use set_blv_found.
1631 (Fkill_local_variable): Likewise.
1633 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
1635 * nsfont.m (ns_ascii_average_width): Ensure the string
1636 ascii_printable is initialized with a null-terminated character
1637 array. Otherwise, it can contain undesired extra characters.
1639 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1641 port new setting code to Sun C 5.8 2005/10/13
1642 * chartab.c, lisp.h (char_table_set, char_table_set_range):
1643 Return void, not Lisp_Object. Otherwise, the compiler
1644 complains about (A?B:C) where B is void and C is Lisp_Object
1645 when compiling CHAR_TABLE_SET, due to the recent change to
1646 the API of sub_char_table_set_contents.
1648 2012-08-18 Chong Yidong <cyd@gnu.org>
1650 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
1651 for the string case (Bug#3874).

2478 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
2479 * w32.c (init_environment): Change the default values of many
2480 environment variables in dflt_envvars[] to NULL, to avoid pushing
2481 them into environment when they were not already defined.
2482 Remove the code that deletes site-lisp subdirectories from the default
2483 value of EMACSLOADPATH, as it is no longer needed.
2484 (check_windows_init_file): Now external, not static.
2485 Use Vload_path as is, without adding anything, as this function is now
2486 called when Vload_path is already set up.
2488 * w32.h (check_windows_init_file): Add prototype.
2490 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

2533 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
2534 Remove unnecessary pointer casts.
2535 * alloc.c (record_xmalloc): New function.
2536 * lisp.h (record_xmalloc): New decl.
2537 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
2538 more like a function. This is because the pointer cast is not
2539 needed. All uses changed.
2540 * print.c (print_string, print_error_message): Avoid length recalc.
2542 Improve fix for macroexp crash with debugging (Bug#12118).
2543 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
2544 ARRAY_MARK_FLAG when checking subscripts, because ASET is
2545 not supposed to be invoked from the garbage collector.

2547 (gc_aset): New function, which is like ASET but can be
2548 used in the garbage collector.

2577 with addition of handling of symlinks and support for 'lstat'.
2578 If possible, get file's attributes and security information by
2579 handle, not by name. Produce S_IFLNK bit for symlinks, when
2580 called from 'lstat'.
2581 (stat, lstat): New functions, call 'stat_worker'.
2582 (symlink, readlink, careadlinkat): Rewritten to create and resolve
2583 symlinks when the underlying filesystem supports them.
2585 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
2587 Fix macroexp crash on Windows with debugging (Bug#12118).
2588 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
2589 checking subscripts; problem introduced with the recent
2590 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
2591 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
2592 since it's used in non-static inline functions now.
2594 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
2595 Don't assume buffer size fits in 'int'. Remove unused local.

2616 * dispnew.c (DISPEXTERN_INLINE):
2617 * sysdep.c (SYSTIME_INLINE):
2618 Define to EXTERN_INLINE, so that the corresponding functions
2619 are compiled into code.

2621 (INLINE_HEADER_END): New macros.
2622 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

2642 hard-coding the path separator.
2644 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
2646 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
2647 This how ASET and AREF are supposed to work, and makes
2648 it easier to think about future improvements. See
2649 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
2650 * charset.h (set_charset_attr): New function.

3143 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
3144 would have been more obvious.
3145 * emacs.c: Do not include <verify.h>; no longer needed.
3146 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
3147 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
3148 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3149 Remove; now done in lisp.h.
3150 * lisp.h (PUBLISH_TO_GDB): New macro.
3151 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
3152 (DATA_SEG_BITS): Use it.
3153 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
3154 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3155 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3156 not be usable in #if. This simplifies things.
3158 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
3160 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
3162 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
3164 Simplify export of symbols to GDB (Bug#12036).
3165 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3166 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3167 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3168 Adjust to changes in lisp.h and emacs.c, by using
3169 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
3170 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
3171 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
3172 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
3173 instead of gdb_valbits.
3174 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
3175 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
3176 instead of gdb_array_mark_flag.
3177 (xboolvector): Get size from $->size, not $->header.size.
3178 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
3179 (xreload, hook-run, hookpost-run): Remove.
3180 * emacs.c: Include <verify.h>.
3181 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
3182 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
3184 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
3185 (gdb_USE_LSB_TAG): New enum constants.
3186 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3187 Also define these as enum constants, so they're visible to GDB.
3188 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
3189 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
3190 as constants, so they're visible to GDB.
3191 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
3192 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
3193 Now enum constants, not macros, so they're visible to GDB.
3194 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
3195 more convenient now. All uses changed.
3196 (VALMASK) [USE_LSB_TAG]: Also define in this case.
3197 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
3199 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

3206 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
3207 add argument, tune behavior, and adjust all callers.
3209 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
3211 Use typedef for EMACS_INT, EMACS_UINT.
3212 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
3213 than macros. This simplifies debugging in the usual case, since
3214 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
3215 and it allows expressions involving EMACS_INT casts.
3216 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
3218 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

3228 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
3230 Adjust buffer text indirection counters at the end of Fkill_buffer.
3231 * buffer.c (Fkill_buffer): Adjust indirection counters when the
3232 buffer is definitely dead. This should really fix an issue reported
3233 by Christoph Scholtes again. (Bug#12007).
3234 (init_buffer_once): Initialize indirection counters of
3235 buffer_defaults and buffer_local_symbols (for sanity and safety).
3237 2012-07-24 Eli Zaretskii <eliz@gnu.org>
3239 * xdisp.c (init_iterator): Don't compute dimensions of truncation
3240 and continuation glyphs on tooltip frames, leave them at zero.
3241 Avoids continued lines in tooltips. (Bug#11832)
3243 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
3245 Simplify copy_overlay.
3246 * buffer.c (copy_overlay): Simplify. Use build_marker.

3252 or invalid. (Bug#12025)
3254 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
3255 it signals an error when a tooltip frame is being created.
3257 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3259 Cleanup miscellaneous objects allocation and initialization.

3266 (build_overlay): Add prototype.
3268 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3270 Swap buffer text indirection counters in Fbuffer_swap_text.
3271 * buffer.c (Fbuffer_swap_text): Swap indirections too.
3272 This avoids crash reported by Christoph Scholtes at
3273 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
3275 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
3277 * nsmenu.m (Popdown_data): New struct.

3300 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
3302 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
3303 as it's limited by the amount of memory, not by INT_MAX.
3305 2012-07-21 Eli Zaretskii <eliz@gnu.org>
3307 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
3308 in special-event-map. See the discussion at

3458 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3460 * eval.c (Fdefvar): Don't check constants since we only set the var if
3461 it's not yet defined anyway (bug#11904).
3463 * lisp.h (last_undo_boundary): Declare new var.
3464 * keyboard.c (command_loop_1): Set it.
3465 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
3466 were auto-added by the command loop (bug#11774).

4048 which are not functions. All uses rewritten to use:
4049 (make_emacs_time): New function.
4050 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
4051 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4052 not functions. All uses rewritten to use the following, respectively:

4054 (add_emacs_time, sub_emacs_time): New functions.
4055 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

4081 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4082 * nsterm.m (ns_term_init):
4083 Avoid the need for strncpy, by using build_string or
4084 make_unibyte_string directly. Use dtoastr, not snprintf.
4085 * process.c (Fmake_network_process): Diagnose service names that
4086 are too long, rather than silently truncating them or creating
4087 non-null-terminated names.
4088 (Fnetwork_interface_info): Likewise, for interface names.
4089 * sysdep.c (system_process_attributes) [GNU_LINUX]:
4090 Prefer sprintf to strncat.
4091 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

4117 Optimize pure C strings initialization.
4118 * lisp.h (make_pure_string): Fix prototype.
4119 (build_pure_c_string): New function, defined as static inline. This
4120 provides a better opportunity to optimize away calls to strlen when
4121 the function is called with compile-time constant argument.
4122 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
4123 argument, adjust users accordingly. Use build_pure_c_string where
4125 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
4126 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
4127 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
4129 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4131 Avoid calls to strlen in miscellaneous functions.
4132 * buffer.c (init_buffer): Use precalculated len, adjust if needed.

4154 * s/gnu.h (DATA_START): Move definitions to configure.
4156 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
4157 We include usg5-4-common.h, which defines them both.
4159 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
4160 O_RDONLY already includes it).
4162 Stop ns builds setting the EMACSLOADPATH environment variable.
4163 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4164 Now it does not set EMACSLOADPATH, just returns the load-path string.
4165 * nsterm.h: Update accordingly.
4166 * lread.c [HAVE_NS]: Include nsterm.h.
4167 (init_lread) [HAVE_NS]: Use ns_load_path.

4170 2012-07-09 Glenn Morris <rgm@gnu.org>
4172 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
4173 since the included bsd-common.h does so.
4175 Stop ns builds setting the EMACSPATH environment variable.
4176 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
4177 (ns_init_paths): Do not set EMACSPATH.
4178 * nsterm.h (ns_exec_path): Add it.
4179 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
4182 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
4184 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
4186 * process.c (wait_reading_process_output): 'waitchannels' was unset
4187 when read_kbd || !NILP (wait_for_cell); fix this.
4189 Add GCC-style 'const' attribute to functions that can use it.
4190 * character.h (char_resolve_modifier_mask):
4191 * keyboard.h (make_ctrl_char):
4192 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

4201 Add decls with ATTRIBUTE_CONST.
4203 Minor improvements to make_formatted_string.
4204 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
4205 where int is good enough, as vsprintf returns an int.
4206 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
4208 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4210 Use make_formatted_string to avoid double length calculation.
4211 * lisp.h (make_formatted_string): New prototype.
4212 * alloc.c (make_formatted_string): New function.
4213 * buffer.c (Fgenerate_new_buffer_name): Use it.

4235 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4237 Move marker debugging code under MARKER_DEBUG.
4238 * marker.c (MARKER_DEBUG): Move marker debugging code under
4239 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4240 for bootstrap with --enable-checking (~3x slowdown reported
4241 by Juanma Barranquero <lekktu@gmail.com>).
4242 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4244 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4246 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
4247 See <http://bugs.gnu.org/11825#29>.
4249 2012-07-08 Eli Zaretskii <eliz@gnu.org>
4251 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4252 has no font, use the frame's font. (Bug#11813)
4253 (display_line): Add commentary about displaying truncation glyphs
4255 (produce_special_glyphs): Move here from term.c.
4257 * term.c (produce_special_glyphs): Move to xdisp.c.
4259 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4262 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4264 * xdisp.c (display_line): Avoid warning about implicit declaration
4267 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4269 * lisp.h: Remove empty conditional.
4271 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4273 * lread.c (load_path_check): Now static.
4275 Fix some minor --with-ns problems found by static checking.
4276 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
4277 (x_set_font) [!HAVE_X_WINDOWS]:
4278 * image.c (xpm_load_image) [HAVE_NS]:
4279 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4280 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4281 Remove unused local.
4282 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
4283 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
4284 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
4285 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
4286 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
4287 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
4288 Fix pointer signedness problem.
4289 * xfaces.c (FRAME_X_FONT_TABLE):
4290 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
4292 2012-07-07 Glenn Morris <rgm@gnu.org>
4294 * lread.c (load_path_check): New function, split from init_lread.
4295 (init_lread): Reorganize. Motivation:
4296 If EMACSLOADPATH is set, check/warn about that rather than the
4297 defaults, which we are not going to use. Hence we can remove
4298 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4299 Don't warn if site-lisp directories are missing.
4300 If not installed, start from a blank load-path, since
4301 PATH_LOADSEARCH refers to the eventual installation directories.
4303 2012-07-07 Eli Zaretskii <eliz@gnu.org>
4305 Support truncation and continuation glyphs on GUI frames, when
4306 fringes are disabled. (Bug#11832)
4307 * xdisp.c (init_iterator): Get dimensions of truncation and
4308 continuation glyphs even if on GUI frames.
4309 Adjust it->last_visible_x on GUI frames when the left or right fringes,
4310 or both, are absent.
4311 (start_display, move_it_in_display_line_to): Handle the case of a
4312 GUI frame without a fringe to display continuation or truncation
4314 (insert_left_trunc_glyphs): Support GUI frames: make sure
4315 truncation glyphs overwrite enough glyphs from the current line to
4316 have sufficient space in pixels.
4317 (display_line): Support truncation and continuation glyphs on GUI
4318 frames. If some spare pixels are left on the line after inserting
4319 the truncation glyphs, fill that space with a stretch glyph of a
4320 suitably computed width.
4322 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4323 produce_glyphs, to support GUI sessions.
4325 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4327 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4329 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4331 Do not require float-time's arg to fit in time_t (Bug#11825).
4332 This works better on hosts where time_t is unsigned, and where
4333 float-time is applied to the (negative) difference between two times.
4334 * editfns.c (decode_time_components): Last arg is now double *,
4335 not int *, and means to store all the result as a double, without
4336 worrying about whether the seconds part fits in time_t.
4337 All callers changed.
4338 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4339 All callers changed.
4340 (Ffloat_time): Do not fail merely because the specified time falls
4341 outside of time_t range.
4343 2012-07-07 Glenn Morris <rgm@gnu.org>
4345 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
4346 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
4347 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
4349 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
4351 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
4352 Update dependencies.
4354 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
4356 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4358 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

4360 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
4361 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
4362 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
4363 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
4365 * xfont.c (compare_font_names): Redo to omit the need for casts.
4367 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4369 * xfns.c (Fx_change_window_property): Doc fix.
4370 * w32fns.c (Fx_change_window_property): Doc fix.
4372 * w32fns.c (Fx_window_property): Accept the same arguments as the
4373 X Windows version. Doc fix.
4374 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4376 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4377 Eli Zaretskii <eliz@gnu.org>
4379 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4380 Windows-specific code from nt/config.nt moved here.
4381 Obsolete settings removed.
4383 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4385 * process.c: Avoid unnecessary calls to gettime.
4386 (wait_reading_process_output): Don't get the time of day
4387 when gobbling data immediately and not waiting, as there's no need
4388 for it in that case. This removes a FIXME.
4390 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4392 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4393 is defined (Bug#11768).
4395 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4397 Fix marker debugging code.
4398 * marker.c (byte_char_debug_check): Do not perform the check
4399 if buffer is not multibyte.
4400 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4401 Call byte_char_debug_check with correct arguments.
4403 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4405 Compile marker debugging code only if ENABLE_CHECKING is defined.
4406 * marker.c (byte_char_debug_check, count_markers):
4407 Use only if ENABLE_CHECKING is defined.
4408 (byte_debug_flag): Remove.
4409 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4410 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4412 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4414 Avoid code repetition in marker-related functions.
4415 * marker.c (attach_marker): New function.
4416 (Fset_marker, set_marker_restricted, set_marker_both)
4417 (set_marker_restricted_both): Use it.
4418 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4419 Consistently rename charno to charpos.
4420 (marker_position): Add eassert.
4421 (marker_byte_position): Convert to eassert.
4423 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

4440 * window.c (save_window_save): Likewise.
4442 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4444 Do not use Fdelete_overlay in delete_all_overlays
4445 to avoid redundant calls to unchain_overlay.
4446 * buffer.c (drop_overlay): New function.
4447 (delete_all_overlays, Fdelete_overlay): Use it.
4448 * minibuf.c (get_minibuffer): Fix comment.
4450 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4452 Port to OpenBSD 5.1 amd64.
4453 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4454 This is needed for OpenBSD, and should be harmless on all BSD systems.
4455 Also, include <sys/sysctl.h>, as it should be available on all
4456 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4457 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4458 use p_pid member, not kp_proc.pid.
4460 2012-07-06 Glenn Morris <rgm@gnu.org>
4462 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4464 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

4477 Omit needless casts involving void * pointers and allocation.
4478 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4479 as the former is more robust if P's type is changed.
4480 Prefer xzalloc to xmalloc + memset 0.
4481 Simplify malloc-or-realloc to realloc.
4482 Don't worry about xmalloc returning a null pointer.
4483 Prefer xstrdup to xmalloc + strcpy.
4484 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4486 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4487 alloca of a constant.
4489 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4491 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4492 hscroll is larger than the line width. Fixes long and futile
4493 looping inside extend_face_to_end_of_line (on a TTY) producing
4494 glyphs that are not needed and thrown away.
4496 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4498 * marker.c (set_marker_restricted_both): Simplify by using
4501 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4503 * editfns.c (region_limit): Simplify by using clip_to_bounds.
4505 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
4507 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
4508 not defined (Bug#11768).
4509 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
4510 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
4511 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
4512 followed by gtk_box_set_homogeneous (Bug#11768).
4513 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4514 (update_theme_scrollbar_width, xg_create_scroll_bar):
4515 Use gtk_scrollbar_new (Bug#11768).
4516 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
4517 (is_box_type): New function (Bug#11768).
4518 (xg_tool_item_stale_p): Call is_box_type.
4519 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
4520 with default display (Bug#11768).

4524 * xdisp.c (window_hscroll_limited): New function.
4525 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
4526 coordinates when window's hscroll is set to insanely large
4529 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
4531 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
4532 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
4534 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4537 * lisp.h (xzalloc): New prototype. Omit needless casts.

4592 * fileio.c (time_error_value): Check the right error number.
4593 Problem reported by Troels Nielsen in
4594 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
4596 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4598 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
4599 This should be fixed in a better way; see Eli Zaretskii in
4600 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
4601 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
4603 * fileio.c (time_error_value): Rename from special_mtime.
4604 The old name's problems were noted by Eli Zaretskii in
4605 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
4607 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
4608 This variable's comment says Emacs needs at least one GDB-visible
4609 symbol of type enum pvec_type, to work around GDB problems.
4610 The symbol's value doesn't matter.
4612 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
4613 that causes compilation to fail on pre-C99 compilers.
4615 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
4617 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
4618 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
4620 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4622 * buffer.c (init_buffer_once): Fix initialization of
4623 headers for buffer_defaults and buffer_local_symbols.
4624 Reported by Juanma Barranquero <lekktu@gmail.com>.
4626 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
4628 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
4629 * lisp.h (enum pvec_type): Use fewer bits.
4630 (PSEUDOVECTOR_SIZE_BITS): New constant.
4631 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
4632 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
4633 change in pvec_type.
4634 (PSEUDOVECTOR_TYPEP): New macro.
4635 (TYPED_PSEUDOVECTORP): Use it.
4636 * fns.c (internal_equal): Adapt code to extract pvectype.

4638 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
4639 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
4640 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
4641 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
4642 (sweep_vectors): Use it. Use local var `total_bytes' instead of
4643 abusing vector->header.next.nbytes.
4644 (live_vector_p): Use PVEC_TYPE.
4645 (mark_object): Adapt code to extract pvectype. Use switch.
4647 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4649 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
4650 Tighten new eassert a bit.
4652 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4654 Fix compilation with --enable-gcc-warnings and -O1
4656 * doprnt.c (doprnt): Change type of tem to int, initialize
4657 to avoid compiler warning. Add eassert.
4658 * search.c (simple_search): Initialize match_byte to avoid
4659 compiler warning. Add eassert.
4661 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4663 Avoid weird behavior with large horizontal scrolls.
4664 Without this change, for example, large hscroll values would
4665 mess up Emacs's display on Fedora 15 x86, presumably due to
4666 overflows in int calculations in the display code.
4667 Also, if buffers had long lines, Emacs would freeze.
4668 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
4669 (set_window_hscroll): New function, containing the old guts of
4670 Fset_window_hscroll. Return the clipped value.
4671 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
4672 This avoids the need to check against PTRDIFF_MAX.
4674 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
4676 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4678 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
4680 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4682 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
4683 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
4684 since GCC 4.4.6 issues a bogus warning for them.
4686 Fix bugs in file timestamp newness comparisons.
4687 * fileio.c (Ffile_newer_than_file_p):
4688 * lread.c (Fload): Use full timestamp resolution of files,
4689 not just the 1-second resolution, so that files that are only
4690 slightly newer still count as newer.
4691 * fileio.c (Ffile_newer_than_file_p): Don't assume file
4692 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
4694 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
4696 * fileio.c: Improve handling of file time marker. (Bug#11852)
4697 (special_mtime): New function.
4698 (Finsert_file_contents, Fverify_visited_file_modtime):
4699 Use it to set special mtime values consistently.
4701 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
4703 * fileio.c (Finsert_file_contents): Properly handle st_mtime
4704 marker for non-existing file. (Bug#11852)
4706 2012-07-03 Glenn Morris <rgm@gnu.org>
4708 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
4709 and did not make it into globals.h).
4711 2012-07-03 Tom Tromey <tromey@redhat.com>
4713 * window.c (Fset_window_margins, Fset_window_fringes)
4714 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
4715 * textprop.c (Fprevious_property_change): No longer static.
4716 * syntax.c (Fsyntax_table_p): No longer static.

4745 * window.h: Remove EXFUNs.

4747 * xterm.h: Remove EXFUN.
4749 2012-07-03 Glenn Morris <rgm@gnu.org>
4751 * lisp.h (Frandom): Make it visible to C.
4752 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
4753 buffer for invisible buffers. (Bug#1229)
4755 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4757 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
4758 values which aren't power of 2.
4759 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
4760 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
4763 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
4765 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
4767 * alloc.c (mark_object): Revert part of last patch to use `switch'.
4769 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4771 * alloc.c (allocate_vector_block): Remove redundant
4772 calls to mallopt if DOUG_LEA_MALLOC is defined.
4773 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
4774 avoid calls to mallopt if zero_vector is returned.
4776 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4778 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
4779 is enabled, avoid dereferencing NULL current_sblock if
4782 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4784 Cleanup basic buffer management.
4785 * buffer.h (struct buffer): Change layout to use generic vector
4786 marking code. Fix some comments. Change type of 'clip_changed'
4787 to bitfield. Remove unused #ifndef old.
4788 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
4789 (GET_OVERLAYS_AT): Fix indentation.
4790 (for_each_per_buffer_object_at): New macro.

4793 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
4794 * alloc.c (allocate_buffer): Adjust to match new layout of
4795 struct buffer. Fix comment.
4796 (mark_overlay): New function.

4799 (mark_object): Use it. Adjust marking of misc objects
4800 and related comments.
4802 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
4804 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
4805 wrapper that is not needed because the wrapped code is a no-op (zero
4806 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
4807 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
4809 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
4811 * alloc.c (mark_buffer): Simplify. Remove prototype.
4812 (mark_object): Add comment. Reorganize marking of vector-like
4813 objects. Use CHECK_LIVE for all vector-like objects except buffers
4814 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
4815 Avoid redundant calls to mark_vectorlike for bool vectors.
4817 2012-06-30 Glenn Morris <rgm@gnu.org>
4819 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
4821 * epaths.in (PATH_SITELOADSEARCH): New.
4822 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
4823 This is rather than relying on --enable-locallisppath elements
4824 having "site-lisp" in their names. (Bug#10208#25, 11658)
4826 2012-06-30 Eli Zaretskii <eliz@gnu.org>
4828 * w32proc.c (sys_select): Accept and ignore one more argument.
4830 * w32.c (emacs_gnutls_pull): Call select with one more argument.
4832 * sysselect.h [DOS_NT]: Don't include sys/select.h.
4833 (pselect) [!MS_DOS]: Redirect to sys_select.
4835 * sysdep.c: Don't include dos.h and dosfns.h.
4837 * process.c (sys_select):
4838 * msdos.c (sys_select): Accept one more argument and ignore it.
4840 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
4841 adapt data types and code to that.
4844 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
4845 which clashes with the gnulib function of the same name.
4847 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
4849 * font.c (font_style_to_value, font_style_symbolic)
4850 (font_prop_validate_style): Add type checks for values in
4853 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
4855 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
4858 2012-06-29 Eli Zaretskii <eliz@gnu.org>
4860 * xdisp.c (try_window_id): Undo last change.
4862 * w32.c (getwd): Adjust commentary about startup_dir.
4863 (init_environment): Always call sys_access, even in non-MSVC
4864 builds. Don't chdir to the directory of the Emacs executable.
4865 This undoes code from 1997 which was justified by the need to
4866 "avoid conflicts when removing and renaming directories". But its
4867 downside was that every relative file name was being interpreted
4868 relative to the directory of the Emacs executable, which can never
4869 be TRT. In particular, it broke sys_access when called with
4870 relative file names.
4871 (sys_access): Map GetLastError to errno.
4873 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4875 * window.h (struct window): Change type of 'fringes_outside_margins'

4879 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
4882 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
4884 * gnutls.c (emacs_gnutls_handshake):
4885 Add QUIT to make the loop interruptible.
4887 2012-06-29 Glenn Morris <rgm@gnu.org>
4889 * charset.c (init_charset): Make lack of etc/charsets fatal.
4891 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4893 * editfns.c (region_limit): Fix type mismatch.
4895 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4897 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
4898 undefined. Convert from xassert to eassert.
4899 * nsmenu.m: Convert from xassert to eassert.
4900 * nsterm.m: Likewise.
4902 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
4904 * editfns.c (region_limit): Clip to narrowing (bug#11770).
4906 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
4908 Avoid integer overflow on scroll-left and scroll-right.
4909 * window.c (HSCROLL_MAX): New macro.
4910 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
4911 overflow when requested scroll falls outside ptrdiff_t range.
4913 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
4915 * window.h (struct window): Change type of 'hscroll',
4916 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
4917 'last_modified' and 'last_overlay_modified' to EMACS_INT.
4918 Adjust users accordingly.
4919 * xdisp.c (try_cursor_movement): Replace type check with eassert.
4920 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
4921 from EMACS_INT to ptrdiff_t.
4922 (make_window): Omit redundant initialization.
4924 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
4926 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
4928 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
4930 * window.h (struct window): Change type of 'use_time' and
4931 'sequence_number' from Lisp_Object to int.
4932 * frame.c (make_frame): Adjust users accordingly.
4933 * print.c (print_object): Likewise.
4934 * window.c (select_window, Fwindow_use_time, make_parent_window)
4935 (make_window): Likewise.
4937 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
4939 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
4940 enabled with --enable-checking=[all,glyphs] configure option.
4941 Fix GLYPH_DEBUG usage assuming that it may be undefined,
4942 adjust comments accordingly.
4943 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
4944 undefined, adjust comments accordingly.

4954 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
4956 Generalize run-time debugging checks.
4957 * dispextern.h (XASSERTS): Remove.
4958 * fontset.c (xassert): Remove.

5065 Use sprintf return value instead of invoking strlen on result.
5066 In the old days this wasn't portable, since some sprintf
5067 implementations returned char *. But they died out years ago and
5068 Emacs already assumes sprintf returns int.
5069 Similarly for float_to_string.
5070 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

5078 Use sprintf or float_to_string result to avoid need to call strlen.
5079 * data.c (Fnumber_to_string):
5080 Use make_unibyte_string, since the string must be ASCII.
5081 * lisp.h, print.c (float_to_string): Now returns int length.
5082 * term.c (produce_glyphless_glyph):
5083 Use sprintf result rather than recomputing it.
5085 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
5086 * Makefile.in (ALL_CFLAGS):

5118 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

5123 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
5124 instead of truncating it to 63 (admittedly a generous limit).

5184 * keyboard.c (kbd_buffer_get_event):
5185 * process.c (Faccept_process_output):

5254 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5256 Support higher-resolution time stamps (Bug#9000).
5257 The time stamps are only nanosecond-resolution at the C level,
5258 since that's the best that any real-world system supports now.
5259 But they are picosecond-resolution at the Lisp level, as that's
5260 easy, and leaves room for future OS improvements.
5262 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5265 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5266 Don't get current time unless it's needed.
5268 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5269 now provides it if it's absent.
5270 (start_atimer): Port to higher-res time stamps.
5271 Check for time stamp overflow. Don't get current time more
5272 often than is needed.
5274 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5275 Include systime.h, not time.h.
5276 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
5278 * dired.c: Include stat-time.h.
5279 (Ffile-attributes): File times now have higher resolution.
5281 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
5282 (struct image): Timestamp now has higher resolution.
5284 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5285 has at least microseconds now. All uses removed.
5286 (update_frame, update_single_window, update_window, update_frame_1)
5287 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5288 (duration_to_sec_usec): Remove; no longer needed.
5290 * editfns.c (time_overflow): Now extern.
5291 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
5292 (float-time, Fformat_time_string, Fcurrent_time_string)

5296 (decode_time_components, lisp_seconds_argument): New functions.
5297 (make_time): Now static.
5298 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
5299 Report an error if the time is invalid, rather than having the caller
5302 * fileio.c: Include <stat-time.h>
5303 (Fcopy_file): Copy higher-resolution time stamps.
5304 Prefer to set the time stamp via a file descriptor if that works.
5305 (Fset_file_times, Finsert_file_contents, Fwrite_region)
5306 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
5307 (Fvisited_file_modtime, Fset_visited_file_modtime):
5308 Support higher-resolution time stamps.
5310 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
5312 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
5314 * image.c (prepare_image_for_display, clear_image_cache)
5315 (lookup_image): Port to higer-resolution time stamps.
5317 * keyboard.c (start_polling, bind_polling_period):
5318 Check for time stamp overflow.
5319 (read_char, kbd_buffer_get_event, timer_start_idle)
5320 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
5321 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5322 Port to higher-resolution time stamps. Do not assume time_t is signed.
5323 (decode_timer): New function. Timers are now vectors of length 9,
5324 not 8, to accommodate the picosecond component.
5325 (timer_check_2): Use it.
5327 * nsterm.m (select_timeout, timeval_subtract): Remove.
5328 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5329 as they're a bit more accurate and handle overflow better.
5330 (ns_select): Change prototype to be compatible with pselect.
5331 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5332 * nsterm.h (ns_select): Adjust prototype.
5334 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5335 us-resolution time stamps.
5336 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5338 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5340 * lisp.h (time_overflow): New decl.
5341 (wait_reading_process_output): First arg is now intmax_t, not int,
5342 to accommodate larger waits.
5344 * process.h (struct Lisp_Process.read_output_delay):
5345 Now counts nanoseconds, not microseconds.
5346 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
5348 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
5349 (wait_reading_process_output):
5350 Port to ns-resolution time stamps.
5351 (Faccept_process_output, wait_reading_process_output):
5352 Check for time stamp overflow. Do not assume time_t is signed.
5353 (select_wrapper): Remove; we now use pselect.
5354 (Fprocess_attributes): Now generates ns-resolution time stamps.
5356 * sysdep.c: Include utimens.h. Don't include utime.h
5357 or worry about struct utimbuf; gnulib does that for us now.
5358 (gettimeofday): Remove; gnulib provides a substitute.
5359 (make_timeval): New function.
5360 (set_file_times): Now sets ns-resolution time stamps.
5361 New arg FD; all uses changed.
5362 (time_from_jiffies, ltime_from_jiffies, get_up_time)
5363 (system_process_attributes):
5364 Now returns ns-resolution time stamp. All uses changed.
5365 Check for time stamp overflow.
5367 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5368 provides a substitute now.
5370 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5371 since it guarantees struct timespec.
5372 (EMACS_TIME): Now struct timespec, so that we can support
5373 ns-resolution time stamps.
5374 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5375 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5376 (EMACS_USECS): Remove.
5377 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5378 so multiply the arg by 1000 before storing it.
5379 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
5381 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
5382 Port to ns-resolution time stamps.
5383 (EMACS_TIME_NEG_P): Remove; replaced by....
5384 (EMACS_TIME_SIGN): New macro.
5385 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
5386 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
5387 (set_file_times, make_time, lisp_time_argument): Adjust signature.
5388 (make_timeval, make_lisp_time, decode_time_components): New decls.
5389 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
5390 that it mishandled time_t overflow. You can't compare by subtracting!
5391 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
5392 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
5394 * term.c: Include <sys/time.h>.
5395 (timeval_to_Time): New function, for proper overflow wraparound.
5396 (term_mouse_position, term_mouse_click): Use it.
5398 * undo.c (record_first_change): Support higher-resolution time stamps
5400 (Fprimitive_undo): Use them when restoring time stamps.
5402 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
5403 (w32_get_internal_run_time):
5404 Port to higher-resolution Emacs time stamps.
5405 (ltime): Now accepts single 64-bit integer, as that's more convenient
5408 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
5410 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
5411 for compatibility with pselect. Support ns-resolution time stamps.
5413 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
5415 * xselect.c (wait_for_property_change, x_get_foreign_selection):
5416 Check for time stamp overflow, and support ns-resolution time stamps.
5418 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
5419 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
5420 (timeval_subtract): Remove; no longer needed.
5421 (XTflash, XTring_bell, x_wait_for_event):
5422 Port to ns-resolution time stamps. Don't assume time_t is signed.
5424 2012-06-22 Chong Yidong <cyd@gnu.org>
5426 * xdisp.c (x_consider_frame_title): Revert last change.
5428 2012-06-22 Eli Zaretskii <eliz@gnu.org>
5430 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
5431 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5432 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
5433 staticidx goes up to 1597 out of 1600 = 0x640.)
5435 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
5437 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
5438 Otherwise, the umask might be mistakenly 0 while handling input signals.
5440 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

5707 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
5708 Use an inline function on all platforms when using the union type,
5709 since this is simpler and 'static inline' can be used portably

5854 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
5855 would mishandle a string argument "Xc" if X was a multibyte

5921 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
5923 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
5925 For a 'struct window', replace some Lisp_Object fields to
5926 bitfields where appropriate, remove unused fields.
5927 * window.h (struct window): Remove unused 'last_mark_x' and
5928 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
5929 change it's type from Lisp_Object to bitfield.
5930 Change type of 'force_start', 'optional_new_start',
5931 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
5932 fields from Lisp_Object to bitfield. Adjust users accordingly.
5934 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5936 Pacify gcc -Wdouble-precision when using Xaw.
5937 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
5938 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
5939 Use 'float' consistently, rather than 'float' in most places
5940 and 'double' in a couple of places.
5942 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5944 * xdisp.c (handle_stop): Detect whether we have overlay strings
5945 loaded by testing it->current.overlay_string_index to be
5946 non-negative, instead of checking whether n_overlay_strings is
5947 positive. (Bug#11587)
5949 2012-05-31 Chong Yidong <cyd@gnu.org>
5951 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
5953 * doc.c (Fsubstitute_command_keys): Doc fix.
5955 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5957 * search.c (search_buffer): Remove calls to
5958 r_alloc_inhibit_buffer_relocation, as it is now called by
5959 maybe_unify_char, which was the cause of relocation of buffer text
5962 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5964 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
5965 for the duration of call to load_charset, to avoid problems with
5966 callers of maybe_unify_char that access buffer text through C
5969 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
5970 decrement the inhibition flag, instead of just setting or
5973 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5975 Remove obsolete '#define static' cruft.
5976 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
5977 This #undef was "temporary" in 2000; it is no longer needed
5978 now that '#define static' has gone away.
5979 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
5980 (gray_bitmap_bits): Remove; no longer needed.
5981 All uses replaced with definiens.
5982 * xterm.c: Include "bitmaps/gray.xbm".
5984 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
5986 Clean up __executable_start, monstartup when --enable-profiling.
5987 The following changes affect the code only when profiling.
5988 * dispnew.c (__executable_start): Rename from safe_bcopy.
5989 Define only on platforms that need it.
5990 * emacs.c: Include <sys/gmon.h> when profiling.
5991 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
5992 (__executable_start): Remove decl, since lisp.h does it now.
5993 (safe_bcopy): Remove decl; no longer has that name.
5994 (main): Coalesce #if into single bit of code, for simplicity.
5995 Cast pointers to uintptr_t, since standard libraries want integers
5997 * lisp.h (__executable_start): New decl.
5999 2012-05-31 Glenn Morris <rgm@gnu.org>
6001 * image.c (Fimagemagick_types): Doc fix.
6003 2012-05-30 Jim Meyering <meyering@redhat.com>
6005 * callproc.c (Fcall_process_region): Include directory component
6006 in mkstemp error message (Bug#11586).

6018 (Qdefun): Move from eval.c.
6019 * lisp.h (Qdefun): Remove.
6020 * lread.c (read1): Tiny simplification.
6022 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
6024 Do not create empty overlays with the evaporate property (Bug#9642).
6025 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6026 Bug#9642, but explicitly check that the buffer the overlay would
6027 be moved to is live and rearrange lines to make sure that errors
6028 will not put the overlay in an inconsistent state.
6029 (Fdelete_overlay): Cosmetics.
6031 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6033 * w32term.c (my_bring_window_to_top): New function.
6034 (x_raise_frame): Use handle returned by DeferWindowPos, which
6035 could be different from the original one.
6036 Call my_bring_window_to_top instead of my_set_foreground_window.
6039 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6040 by calling BringWindowToTop.
6042 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6043 (WM_EMACS_END): Increase by one.
6045 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6047 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6048 This avoids undefined behavior that might cause the eassert
6049 to not catch an out-of-range value.
6051 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6053 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
6054 Update dependencies.
6056 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6058 * bidi.c (bidi_mirror_char): Fix last change.
6060 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
6062 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
6063 when referring to sectname field in printf format.
6065 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
6067 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6068 Only r_alloc_inhibit_buffer_relocation needed to be added;
6069 the others were already declared.
6071 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6072 before checking whether it's out of range. Put the check inside
6074 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6076 2012-05-27 Ken Brown <kbrown@cornell.edu>
6078 * callproc.c (Fcall_process): Restore a line that was accidentally
6079 commented out in the 2011-02-13 change (bug#11547).
6081 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6083 * lisp.h [REL_ALLOC]: Add prototypes for external functions
6084 defined on ralloc.c.
6086 * buffer.c [REL_ALLOC]: Remove prototypes of
6087 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
6088 they are now on lisp.h.
6090 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6092 * search.c (search_buffer): Use it to inhibit relocation of buffer
6093 text while re_search_2 is doing its job, because re_search_2 is
6094 passed C pointers to buffer text. (Bug#11519)
6096 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6099 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6100 state after an additional call to move_it_in_display_line_to, keep
6101 the values of it->max_ascent and it->max_descent found for the
6103 (pos_visible_p): Revert the comparison against bottom_y to what it
6104 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
6107 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6109 Fix coding-related core dumps with gcc -ftrapv.
6110 The code was computing A - B, where A and B are pointers, and B is
6111 random garbage. This can lead to core dumps on platforms that
6112 have special pointer registers, and it also leads to core dumps on
6113 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6114 A - B only when B is initialized properly.
6115 * coding.c (coding_set_source, coding_set_destination): Return void.
6116 (coding_change_source, coding_change_destinations): New functions,
6117 with the old behaviors of coding_set_source and coding_set_destination.
6118 All callers that need an offset changed to use these new functions.
6120 2012-05-26 Glenn Morris <rgm@gnu.org>
6122 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
6124 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6126 Extend mouse support on W32 text-mode console.
6127 * xdisp.c (draw_row_with_mouse_face):
6128 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6130 * w32console.c: Include window.h.
6131 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6133 (initialize_w32_display): Initialize mouse-highlight data.
6135 * w32inevt.c: Include termchar.h and window.h.
6136 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6137 moves, call note_mouse_highlight. If help_echo changed, call
6138 gen_help_event to produce help-echo message in the echo area.
6139 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6142 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6144 * lread.c (read1): Simplify slightly to avoid an overflow warning
6145 with GCC 4.7.0 on x86-64.
6147 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6149 * bidi.c (bidi_mirror_char): Revert last change: an int is
6150 definitely wide enough here.
6152 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
6154 Fix integer width and related bugs (Bug#9874).
6155 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
6156 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
6157 (string_bytes, check_sblock, allocate_string_data):

6161 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
6162 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
6164 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6165 (allocate_pseudovector):
6166 Use int, not EMACS_INT, where int is wide enough.
6167 (inhibit_garbage_collection, Fgarbage_collect):
6168 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6169 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
6170 int might not be wide enough.
6171 (bidi_cache_search, bidi_cache_find, bidi_init_it)
6172 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6173 (bidi_at_paragraph_end, bidi_find_paragraph_start)
6174 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
6175 (bidi_level_of_next_char, bidi_move_to_visually_next):
6176 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6177 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
6178 (Fkill_buffer, Fset_buffer_major_mode)
6179 (advance_to_char_boundary, Fbuffer_swap_text)
6180 (Fset_buffer_multibyte, overlays_at, overlays_in)
6181 (overlay_touches_p, struct sortvec, record_overlay_string)
6182 (overlay_strings, recenter_overlay_lists)
6183 (adjust_overlays_for_insert, adjust_overlays_for_delete)
6184 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
6185 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
6186 (Foverlay_recenter, last_overlay_modification_hooks_used)
6187 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6188 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6189 (validate_region): Omit unnecessary test for b <= e,
6190 since that's guaranteed by the previous test.
6191 (adjust_overlays_for_delete): Avoid pos + length overflow.
6192 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6193 (report_overlay_modification):
6194 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6195 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
6196 Omit pointer cast, which isn't needed anyway, and doesn't work
6197 after the EMACS_INT -> ptrdiff_t change.
6198 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
6199 * buffer.h: Adjust decls to match defn changes elsewhere.
6200 (struct buffer_text, struct buffer):
6201 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6202 Use EMACS_INT, not int, where int might not be wide enough.
6203 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
6204 not int, to avoid needless 32-bit limit on 64-bit hosts.
6205 (exec_byte_code): Use tighter memory-full test, one that checks
6206 for alloca overflow. Don't compute the address of the object just
6207 before an array, as that's not portable. Use EMACS_INT, not
6208 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
6209 * callint.c (Fcall_interactively):
6210 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6211 * callproc.c (call_process_kill, Fcall_process):
6212 Don't assume pid_t fits into an Emacs fixnum.
6213 (call_process_cleanup, Fcall_process, child_setup):

6215 (call_process_cleanup, Fcall_process, delete_temp_file)
6216 (Fcall_process_region):
6217 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6218 (Fcall_process): Simplify handling of volatile integers.
6219 Use int, not EMACS_INT, where int will do.
6220 * casefiddle.c (casify_object, casify_region, operate_on_word)
6221 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
6222 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6223 (casify_object): Avoid integer overflow when overallocating buffer.
6224 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
6225 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
6226 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
6227 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6228 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6229 integers are now checked earlier. All uses replaced with XINT.
6231 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6232 For CCL_MapSingle, check that content and value are in int range.
6233 (ccl_driver, Fregister_code_conversion_map):
6234 Check that Vcode_version_map_vector is a vector.
6235 (resolve_symbol_ccl_program): Check that vector header is in range.
6236 Always copy the vector, so that we can check its contents reliably
6237 now rather than having to recheck each instruction as it's being
6238 executed. Check that vector words fit in 'int'.
6239 (ccl_get_compiled_code, Fregister_ccl_program)
6240 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6241 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
6242 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
6243 contents are in range.
6244 (Fccl_execute_on_string): Check that status is in range.
6245 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
6246 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
6247 Accept and return EMACS_INT, not int, because callers can pass values
6249 (c_string_width, strwidth, lisp_string_width, chars_in_text)
6250 (multibyte_chars_in_text, parse_str_as_multibyte)
6251 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
6252 (str_as_unibyte, str_to_unibyte, string_count_byte8)
6253 (string_escape_byte8, Fget_byte):
6254 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6255 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
6256 avoid mishandling large integers.
6257 * character.h: Adjust decls to match defn changes elsewhere.
6258 * charset.c (load_charset_map_from_file, find_charsets_in_text)
6259 (Ffind_charset_region):
6260 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6261 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
6262 (load_charset_map_from_vector, Fdefine_charset_internal):
6263 Don't assume fixnum fits in int.
6264 (load_charset_map_from_vector, Fmap_charset_chars):
6265 Remove now-unnecessary CHECK_NATNUMs.
6266 (Fdefine_charset_internal): Check ranges here, more carefully.
6267 Don't rely on undefined behavior with signed left shift overflow.
6268 Don't assume unsigned int fits into fixnum, or that fixnum fits
6269 into unsigned int. Don't require max_code to be a valid fixnum;
6270 that's not true for gb10830 4-byte on a 32-bit host. Allow
6271 invalid_code to be a cons, for the same reason. Require code_offset
6272 to be a character. Avoid int overflow if max_char is close
6274 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
6275 this is intended anyway and avoids some undefined behavior.
6276 (load_charset_map): Pass unsigned, not int, as 2nd arg of
6277 INDEX_TO_CODE_POINT, as that's what it expects.
6278 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
6279 * charset.h (DECODE_CHAR): Return int, not unsigned;
6280 this is what was intended anyway, and it avoids undefined behavior.
6281 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
6282 integer-overflow issues.
6283 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
6284 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
6285 where the argument is EMACS_INT, and this behavior is not intended.
6286 * chartab.c (Fmake_char_table, Fset_char_table_range)
6287 (uniprop_get_decoder, uniprop_get_encoder):
6288 Don't assume fixnum fits in int.
6289 * cmds.c (move_point): New function, that does the gist of
6290 Fforward_char and Fbackward_char, but does so while checking
6291 for integer overflow more accurately.
6292 (Fforward_char, Fbackward_char): Use it.
6293 (Fforward_line, Fend_of_line, internal_self_insert)
6294 (internal_self_insert):
6295 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6296 Fix a FIXME, by checking for integer overflow when calculating
6297 target_clm and actual_clm.
6298 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)

6322 (setup_iso_safe_charsets, consume_chars, Funencodable_char_position)
6323 (Fdefine_coding_system_internal):

6327 (Funencodable_char_position, Fcheck_coding_systems_region)
6328 (get_translation, handle_composition_annotation, consume_chars):
6329 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6330 (consume_chars): Rewrite to not calculate an address outside buffer.
6331 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
6332 Don't access memory outside of the args array.
6333 (Fdefine_coding_system_internal): Check for charset-id overflow.

7055 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
7057 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
7058 reference to image_cache->refcount.
7059 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
7061 2012-05-17 Juri Linkov <juri@jurta.org>
7063 * search.c (Fword_search_regexp, Fword_search_backward)
7064 (Fword_search_forward, Fword_search_backward_lax)
7065 (Fword_search_forward_lax): Move functions to isearch.el
7066 (bug#10145, bug#11381).
7068 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
7070 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
7072 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
7074 * lread.c (init_obarray): Declare Qt and Qnil as special.
7076 2012-05-14 Glenn Morris <rgm@gnu.org>
7078 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
7079 Put "libexec" before "bin", for the sake of init_callproc_1.
7081 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7083 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
7085 * unexaix.c: Port to more-recent AIX compilers.
7086 (report_error, report_error_1, make_hdr, copy_sym)
7087 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
7088 Make arguments const char *, not char *, to avoid violations of C
7089 standard and to fix some AIX warnings reported by Gilles Pion.
7091 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7093 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
7094 already have overlays loaded.
7095 (handle_single_display_spec): Before returning without displaying
7096 fringe bitmap, synchronize the bidi iterator with the main display
7097 iterator, by calling iterate_out_of_display_property.
7098 (iterate_out_of_display_property): Detect buffer iteration by
7099 testing that it->string is a Lisp string.
7100 (get_next_display_element): When the current object is exhausted,
7101 and there's something on it->stack, call set_iterator_to_next to
7102 proceed with what's on the stack, instead of returning zero.
7103 (set_iterator_to_next): If called at the end of a Lisp string,
7104 proceed to consider_string_end without incrementing string
7105 position. Don't increment display vector index past the end of
7106 the display vector. (Bug#11417)
7107 (pos_visible_p): Don't report a position visible when move_it_to
7108 stopped at the last line of window, which happens to be scanned
7109 backwards by the bidi iteration. (Bug#11464)
7111 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7113 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7114 and right-margin display specs even if the spec is invalid or we
7115 are on a TTY, and thus unable to display on the fringes.
7116 That's because the text with the property will not be displayed anyway,
7117 so we need to signal to the caller that this is a "replacing"
7118 display spec. This fixes display when the spec is invalid or we
7121 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7123 * unexaix.c (make_hdr): Fix typo in prototype.
7124 This bug broke the build on AIX. Problem reported by Gilles Pion.
7126 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
7128 * keyboard.c (kbd_buffer_get_event): Read special events also in
7129 batch mode. (Bug#11415)
7131 2012-05-12 Glenn Morris <rgm@gnu.org>
7133 * ns.mk: Update for ns_appbindir no longer having trailing "/".
7135 2012-05-12 Eli Zaretskii <eliz@gnu.org>
7137 * lisp.mk (lisp): Add newcomment.elc.
7139 2012-05-12 Glenn Morris <rgm@gnu.org>
7141 * Makefile.in (MKDIR_P): New, set by configure.
7142 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
7144 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
7146 Remove unused function hourglass_started.
7147 * dispextern.h (hourglass_started):
7148 * w32fns.c (hourglass_started):
7149 * xdisp.c (hourglass_started): Remove.
7151 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7153 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7154 Update dependencies.
7156 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7158 * xgselect.c (xg_select): Put maxfds+1 into a var.
7159 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
7161 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7163 2012-05-10 Dave Abrahams <dave@boostpro.com>
7165 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7166 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7168 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7170 * dbusbind.c (xd_registered_buses): New internal Lisp object.
7171 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7172 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7173 Initialize xd_registered_buses.
7175 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7177 Untag more efficiently if USE_LSB_TAG.
7178 This is based on a proposal by YAMAMOTO Mitsuharu in
7179 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7180 For an admittedly artificial (nth 8000 longlist) benchmark on
7181 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7182 Emacs's overall text size by 1%.
7183 * lisp.h (XUNTAG): New macro.
7184 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7185 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7186 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7187 * eval.c (Fautoload):
7188 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7189 * frame.h (XFRAME): Use XUNTAG.
7191 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7192 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7193 Remove unportable assumptions about print widths of types like
7195 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7196 intptr_t when converting between pointer and integer, to avoid GCC
7197 warnings about wrong width.
7199 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7201 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7202 stack for each reader_thread, instead of defaulting to 8MB
7203 determined by the linker. This avoids failures in creating
7204 subprocesses on Windows 7, see the discussion in this thread:
7205 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7207 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7209 Fix up display of the *Minibuf-0* buffer in the mini window.
7210 * keyboard.c (read_char): Don't clear the echo area if there's no
7212 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7213 contents of *Minibuf-0*) if there's no message displayed in its stead.
7215 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7217 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7220 2012-05-06 Chong Yidong <cyd@gnu.org>
7222 * lisp.mk (lisp): Update.
7224 2012-05-05 Jim Meyering <meyering@redhat.com>
7226 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7228 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7230 * data.c (PUT_ERROR): New macro.
7231 (syms_of_data): Use it. Add new error type `user-error'.
7232 * undo.c (user_error): New function.
7233 (Fprimitive_undo): Use it.
7234 * print.c (print_error_message): Adjust print style for `user-error'.
7235 * keyboard.c (user_error): New function.
7236 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7238 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7240 Do not limit current-time-string to years 1000..9999.
7241 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7242 (Fcurrent_time_string): Support any year that is supported by the
7243 underlying localtime representation. Don't use asctime, as it
7244 has undefined behavior for years outside the range -999..9999.
7246 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7248 Fix race conditions involving setenv, gmtime, localtime, asctime.
7249 Without this fix, interrupts could mess up code that uses these
7250 nonreentrant functions, since setting TZ invalidates existing
7251 tm_zone or tzname values, and since most of these functions return
7252 pointers to static storage.
7253 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7254 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7255 Grow the critical sections to include not just invoking
7256 localtime/gmtime, but also accessing these functions' results
7257 including their tm_zone values if any, and any related TZ setting.
7258 (format_time_string): Last arg is now struct tm *, not struct tm **,
7259 so that the struct tm is saved in the critical section.
7260 All callers changed. Simplify allocation of initial buffer, partly
7261 motivated by the fact that memory allocation needs to be outside
7262 the critical section.
7264 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7266 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7267 with RESET_INTERVAL.
7269 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7270 Remove duplicated buffer name initialization.
7272 2012-05-02 Jim Meyering <jim@meyering.net>
7274 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7276 * xfns.c (x_window): Use xstrdup (Bug#11375).
7278 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7280 * xdisp.c (pos_visible_p): If already at a newline from the
7281 display string before the 'while' loop, don't walk back the glyphs
7282 from it3.glyph_row. Solves assertion violation when the display
7283 string begins with a newline (egg.el). (Bug#11367)
7285 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7287 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7290 2012-05-01 Glenn Morris <rgm@gnu.org>
7292 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7293 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7294 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7295 All were removed before 23.1.
7297 * dispnew.c: Remove HAVE_LIBNCURSES test;
7298 it is always true on relevant platforms.
7300 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7301 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7303 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
7305 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
7307 * .gdbinit (xpr): Remove checks for no longer existing misc types.
7308 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
7311 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
7313 Do not avoid creating empty evaporating overlays (Bug#9642).
7314 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7315 That is, do not delete an evaporating overlay if it becomes
7316 empty after its bounds are adjusted to fit within its buffer.
7317 This fix caused other problems, and I'm reverting it until we get
7318 to the bottom of them.
7320 2012-04-27 Chong Yidong <cyd@gnu.org>
7322 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7324 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7326 * xdisp.c (pos_visible_p): If the window start position is beyond
7327 ZV, start the display from buffer beginning. Prevents assertion
7328 violation in init_iterator when the minibuffer window is scrolled
7331 * window.c (window_scroll_pixel_based): Likewise.
7333 2012-04-27 Chong Yidong <cyd@gnu.org>
7335 * keymap.c (where_is_internal): Doc fix (Bug#10872).
7337 2012-04-27 Glenn Morris <rgm@gnu.org>
7339 * fileio.c (Fcopy_file, Fset_file_selinux_context):
7340 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
7342 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7344 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
7345 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
7347 2012-04-26 Eli Zaretskii <eliz@gnu.org>
7349 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7350 display element, check also the underlying string or buffer
7351 character. (Bug#11341)
7353 * w32menu.c: Include w32heap.h.
7354 (add_menu_item): If the call to AppendMenuW (via
7355 unicode_append_menu) fails, disable Unicode menus only if we are
7356 running on Windows 9X/Me.
7358 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7360 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
7361 (xgetint): Add missing shift for LSB tags.
7363 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7365 * keyboard.c (read_char): Don't wipe echo area for select window
7366 events: These might get delayed via `mouse-autoselect-window'
7369 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
7371 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
7372 manipulation of :loaded-from data.
7374 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
7376 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
7377 now a cons (bug#11311).
7379 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7381 Do not create empty overlays with the evaporate property (Bug#9642).
7382 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7383 if it becomes empty after its bounds are adjusted to fit within
7384 its buffer. Without this fix, in a nonempty buffer (let ((o
7385 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7386 yields an empty overlay that has the evaporate property, which is
7387 not supposed to happen.
7389 Fix minor GTK3 problems found by static checking.
7390 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7391 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7392 (struct _EmacsFixedClass, emacs_fixed_get_type):
7393 Move decls here from emacsgtkfixed.h, since they needn't be public.
7394 (emacs_fixed_get_type): Now static.
7395 (emacs_fixed_class_init): Omit unused local.
7396 (emacs_fixed_child_type): Remove; unused.

7398 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7399 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
7400 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
7401 (EMACS_FIXED_GET_CLASS): Remove; unused.
7402 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
7404 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
7405 Problem reported by Juanma Barranquero for Windows -Wunused-function.
7407 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7409 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
7410 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
7411 (__malloc_size_t, __malloc_ptrdiff_t):
7412 Remove. All uses removed, replaced by the definiens if needed,
7413 since we can assume C89 or better now.
7414 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
7415 (protect_malloc_state, align, get_contiguous_space)
7416 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

7422 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
7423 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
7424 Define using prototypes, not old style.
7425 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
7426 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
7427 (align): Don't assume that signed integer overflow wraps around.
7428 Omit unused local var.
7429 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
7430 (_free_internal_nolock, memalign, mallochook, reallochook):
7431 Omit no-longer-needed casts.
7432 (valloc): Use getpagesize, not __getpagesize.
7433 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
7434 (struct hdr): The 'magic' member is now size_t, not unsigned long.
7436 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
7438 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
7440 Move functions from C to Lisp. Make non-blocking method calls
7441 the default. Implement further D-Bus standard interfaces.
7443 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
7444 (QCdbus_request_name_allow_replacement)
7445 (QCdbus_request_name_replace_existing)

7483 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7485 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
7486 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
7487 Do not assume ptrdiff_t is the same width as 'int'.
7489 * alloc.c: Handle unusual debugging option combinations.
7490 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
7491 since the two debugging options are incompatible.
7492 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7494 (mem_init, mem_insert, mem_insert_fixup):
7495 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
7496 (NEED_MEM_INSERT): Remove; no longer needed.
7498 2012-04-22 Leo Liu <sdl.web@gmail.com>
7500 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
7502 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7504 * sysdep.c [__FreeBSD__]: Minor cleanups.
7505 (list_system_processes, system_process_attributes) [__FreeBSD__]:
7506 Use Emacs indenting style more consistently. Avoid some casts.
7507 Use 'double' consistently rather than mixing 'float' and 'double'.

7525 * print.c (print_preprocess): Only check print_depth if print-circle
7527 (print_object): Check for cycles even when print-circle is nil and
7528 print-gensym is t, but only check print_depth if print-circle is nil.
7530 2012-04-20 Chong Yidong <cyd@gnu.org>
7532 * process.c (wait_reading_process_output): If EIO occurs on a pty,
7533 set the status to "failed" and ensure that sentinel is run.

7546 row, return zero immediately.
7547 (try_cursor_movement): If inside continuation line, don't back up
7548 farther than the first row after the header line, if any.
7549 Don't consider the header-line row as "partially visible", even if
7550 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
7552 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

7587 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
7588 New extern decls, to avoid calling undeclared functions.
7589 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
7590 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
7591 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

7593 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
7594 Remove one incorrect comment and fix another.

7608 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
7609 Remove decls. This fixes an "It stinks!".

7613 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
7615 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

7630 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
7631 * s/netbsd.h, s/sol2-6.h:
7632 Remove definition of GC_MARK_STACK, since the default now works.
7633 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
7634 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
7635 no longer the default.
7636 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
7638 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
7640 * lread.c (lisp_file_lexically_bound_p):

7661 2012-04-11 Daniel Colascione <dancol@dancol.org>
7663 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
7664 against is gone. It's better to use vfork now so that when Cygwin
7665 gains a new, working vfork, we use it automatically (bug#10398).
7667 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

7685 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
7687 * w32.c (w32_delayed_load): Record the full path of the library
7688 being loaded (bug#10424).
7690 2012-04-09 Glenn Morris <rgm@gnu.org>
7692 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
7693 not just in the obarray, before snarfing them. (Bug#11036)
7695 * Makefile.in ($(leimdir)/leim-list.el):
7696 Pass EMACS rather than BUILT_EMACS.

7720 * minibuf.c (Fread_variable): Callers changed.
7722 2012-04-09 Eli Zaretskii <eliz@gnu.org>
7724 * xdisp.c (set_cursor_from_row): If the display string appears in
7725 the buffer at position that is closer to point than the position
7726 after the display string, display the cursor on the first glyph of
7727 the display string. Fixes cursor display when a 'display' text
7728 property immediately follows invisible text. (Bug#11094)
7730 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
7732 composite.c: use 'double' consistently
7733 * composite.c (get_composition_id): Use 'double' consistently
7734 instead of converting 'float' to 'double' and vice versa; this is
7735 easier to understand and avoids a GCC warning.
7737 2012-04-09 Glenn Morris <rgm@gnu.org>
7739 * Makefile.in: Generate leim-list with bootstrap-emacs, in
7740 preparation for dumping it with emacs. (Bug#4789)

7762 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
7763 (mark_memory): Mark Lisp_Objects only if pointers might hide in
7764 objects, as mark_maybe_pointer will catch them otherwise.
7765 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
7766 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
7768 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
7770 Fix typo that broke non-Windows builds.
7771 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

7782 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
7783 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
7784 [!WINDOWSNT]: New macros.
7785 (init_libxml2_functions, libxml2_loaded_p): New functions.
7786 (parse_region): Call fn_xmlCheckVersion instead of using the macro
7787 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
7788 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
7789 Calls xmlCleanupParser only if libxml2 was loaded (or statically
7791 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
7792 Call init_libxml2_functions before calling libxml2 functions.
7793 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
7795 * emacs.c: Don't include libxml/parser.h.

7797 xmlCleanupParser directly.
7799 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
7801 2012-04-07 Eli Zaretskii <eliz@gnu.org>

7809 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
7810 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
7811 about subtle differences between FETCH_CHAR* and STRING_CHAR*
7812 macros related to unification of CJK characters. For the details,
7813 see the discussion following the message here:
7814 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
7816 2012-04-04 Chong Yidong <cyd@gnu.org>
7818 * keyboard.c (Vdelayed_warnings_list): Doc fix.
7820 2012-04-01 Eli Zaretskii <eliz@gnu.org>
7822 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

7830 2012-03-31 Eli Zaretskii <eliz@gnu.org>
7832 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
7833 position we get to after a call to move_it_to fails the
7834 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
7835 only if we wind up in a string from display property. (Bug#11063)
7837 * window.c (Fdelete_other_windows_internal): Invalidate the row
7838 and column information about mouse highlight, so that redisplay
7839 restores it after reallocating the glyph matrices. (Bug#7464)
7841 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
7842 string comes from a `display' text property, use the buffer
7843 position of that property as if we actually saw that position in
7845 (move_it_by_lines): Remove the assertion that
7846 "it->current_x == 0 && it->hpos == 0" which can be legitimately
7847 violated when there's a before-string at the beginning of a line.
7850 2012-03-30 Eli Zaretskii <eliz@gnu.org>
7852 * xdisp.c (append_space_for_newline): If the default face was
7853 remapped, use the remapped face for the appended newline.
7854 (extend_face_to_end_of_line): Use the remapped default face for
7855 extending the face to the end of the line.
7856 (display_line): Call extend_face_to_end_of_line when the default
7857 face was remapped. (Bug#11068)

7883 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
7885 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
7887 2012-03-25 Kenichi Handa <handa@m17n.org>
7889 * dispextern.h (struct glyph): Change the bit length of
7890 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
7892 2012-03-24 Eli Zaretskii <eliz@gnu.org>
7894 * s/ms-w32.h (tzname): Include time.h before redirecting to
7895 _tzname. Fixes the MSVC build. (Bug#9960)

7899 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
7902 * xterm.c (XTread_socket): Only modify handling_signal if

7905 2012-03-23 Eli Zaretskii <eliz@gnu.org>
7907 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
7908 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
7909 when fetching a multibyte character consumes more bytes than
7910 CHAR_BYTES returns, due to unification of CJK characters in
7911 string_char. (Bug#11073)
7913 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
7915 * process.c (wait_reading_process_output): Handle pty disconnect
7916 by refraining from sending oneself a SIGCHLD (bug#10933).

7927 2012-03-21 Chong Yidong <cyd@gnu.org>
7929 * xfaces.c (Vface_remapping_alist): Doc fix.
7931 2012-03-20 Eli Zaretskii <eliz@gnu.org>
7933 * w32proc.c (Fw32_set_console_codepage)
7934 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

7945 it fit in a valid range (Bug#11003).
7947 2012-03-18 Eli Zaretskii <eliz@gnu.org>
7949 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
7950 that is not from display property, accept the row as a "cursor
7951 row" if one of the string's character has a non-nil `cursor'
7952 property. Fixes cursor positioning when there are newlines in
7953 overlay strings, e.g. in icomplete.el. (Bug#11035)
7955 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
7957 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

7961 * eval.c (inhibit_lisp_code): Rename from
7962 inhibit_window_configuration_change_hook; move from window.c.
7964 * xfns.c (unwind_create_frame_1, Fx_create_frame):
7965 * window.c (run_window_configuration_change_hook)
7966 (syms_of_window): Callers changed.
7968 2012-03-11 Chong Yidong <cyd@gnu.org>
7970 * keymap.c (Fkey_description): Doc fix (Bug#9700).
7972 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
7974 2012-03-10 Chong Yidong <cyd@gnu.org>

7977 is visible (Bug#10955).
7979 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
7981 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

7986 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
7989 2012-03-03 Glenn Morris <rgm@gnu.org>

8002 2012-03-02 Glenn Morris <rgm@gnu.org>
8004 * buffer.c (buffer-list-update-hook): Doc fix.
8006 2012-02-29 Eli Zaretskii <eliz@gnu.org>

8009 push_it before setting up the iterator for the first overlay
8010 string, even if we have an empty string loaded.
8011 (next_overlay_string): If there's an empty string on the iterator
8012 stack, pop the stack. (Bug#10903)
8014 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8016 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8017 Suggested by Stefan Monnier in
8018 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8019 * alloc.c (widen_to_Lisp_Object): New static function.
8020 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8021 and widening them to Lisp_Objects. This would work even if
8022 USE_LSB_TAG is defined and wide integers are used, which might
8023 happen in a future version of Emacs.
8025 2012-02-25 Chong Yidong <cyd@gnu.org>
8027 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

8042 call when setting menu-bar-lines and tool-bar-lines parameters.
8043 (unwind_create_frame_1): New helper function.
8045 * window.c (inhibit_window_configuration_change_hook): New var.
8046 (run_window_configuration_change_hook): Obey it.
8047 (syms_of_window): Initialize it.
8049 2012-02-22 Chong Yidong <cyd@gnu.org>

8064 when computing $valmask.
8066 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8067 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8068 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8069 It's useless in that case, and it can cause problems on hosts
8070 that allocate halves of EMACS_INT values separately.
8071 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8072 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8073 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8074 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8075 it avoids undefined behavior on hosts where shifting right by more
8076 than the word width has undefined behavior.
8078 2012-02-19 Chong Yidong <cyd@gnu.org>
8080 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
8081 (Funhandled_file_name_directory, Ffile_name_as_directory)

8121 as that creates a dangerous corner case.
8123 * window.c (Fdelete_window_internal): Invalidate the mouse
8124 highlight (Bug#9904).
8126 2012-02-12 Glenn Morris <rgm@gnu.org>

8156 2012-02-07 Chong Yidong <cyd@gnu.org>
8158 * buffer.c (Fbuffer_local_variables)
8159 (buffer_lisp_local_variables): Handle unbound vars correctly;
8160 don't let Qunbound leak into Lisp.
8162 2012-02-07 Glenn Morris <rgm@gnu.org>
8164 * image.c (Fimagemagick_types): Doc fix.
8166 * image.c (imagemagick-render-type): Change it from a lisp object

8202 * character.c (char_width): Return EMACS_INT, not int.
8203 (char_width, c_string_width): Check for overflow when
8204 computing the width; this is possible now that individual
8205 characters can have unbounded width. Problem introduced
8206 by merge from Emacs 23 on 2012-01-19.
8208 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

8878 behave as if the cursor position were at the window margin.
8880 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
8881 and the cursor position is out of bounds, behave as if the cursor

8912 * dispnew.c (verify_row_hash): Call row_hash for computing the
8913 hash code of a row, instead of duplicating code from xdisp.c.
8915 * dispextern.h (row_hash): Add prototype.
8917 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

8951 * image.c (imagemagick_load_image): Fix typo.
8953 2011-11-14 Eli Zaretskii <eliz@gnu.org>
8955 * xdisp.c (display_line): Move the call to

9101 (window_box_right, window_box_right_offset): Declare extern.
9102 Otherwise, these inline functions do not conform to C99 and
9103 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
9104 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
9105 * intervals.c (adjust_intervals_for_insertion)
9106 (adjust_intervals_for_deletion): Now extern, because otherwise the
9107 extern inline functions 'offset_intervals' couldn't refer to it.
9108 (static_offset_intervals): Remove.
9109 (offset_intervals): Rewrite using the old contents of
9110 static_offset_intervals. The old version didn't conform to C99
9111 because an extern inline function contained a reference to an

9283 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
9284 so that this new function doesn't get optimized away by a

9425 * editfns.c: Rewrite current-time-zone so that it invokes
9426 the equivalent of (format-time-string "%Z") to get the time zone name.
9427 This fixes a bug when the time zone name contains characters that
9428 need converting from the system time locale to Emacs internal format.
9429 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9430 that patch fixed format-time-string to do the conversion, but
9431 I forgot to fix current-time-zone.
9432 (format_time_string): New function, containing most of
9433 what Fformat_time_string used to contain.

9438 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9439 Jason Rumney's 2007-06-07 change worked around this bug, but
9441 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9443 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9445 * xdisp.c (start_display): If the character at POS is displayed
9446 via a display vector, reset IT->current.dpvec_index to zero.
9447 (try_window_reusing_current_matrix): If a line ends in a display
9448 vector or the next line starts in a display vector, continue
9449 redrawing the window even though the character position of
9450 start_row was reached.
9453 2011-10-18 Chong Yidong <cyd@gnu.org>
9455 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9456 with nobreak-char-display too.
9458 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9460 Fix part 3 of bug#9771.
9461 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9462 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9463 non-neutral characters if the current character is a paragraph
9464 separator (a.k.a. Newline). This avoids running the same
9465 expensive loop twice, once when we consume the preceding newline
9466 and the other time when the line actually needs to be displayed.
9467 Avoid the loop when we see neutrals on the base embedding level
9468 following a character whose directionality is the same as the
9469 paragraph's. This avoids running the expensive loop when a line
9470 ends in a long sequence of neutrals, like control characters.
9471 Add assertion against STRONG_AL type. Slightly rearrange code
9472 that determines the type of a neutral given the first non-neutral
9474 (bidi_level_of_next_char): Set next_en_pos to zero when
9475 invalidating its info.
9477 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9479 * xdisp.c (push_display_prop): Determine whether to record string
9480 or buffer position by IT->string, not by IT->method. Allow
9481 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9482 (move_it_vertically_backward): Don't look for character position
9483 immediately after the newline when in a continuation line.
9486 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9488 * window.c (coordinates_in_window): Rewrite and delabelize
9489 vertical border check. (Bug#5357) (Bug#9618)
9491 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9493 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9494 errors in XSetWindowBorder (bug#9310).
9496 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9498 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9499 avoid crash when xmalloc overrun checking is enabled.
9501 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9503 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9504 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9505 cursor motion with <left> and <right> arrow keys.
9507 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9508 some callers set that themselves.
9510 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9512 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9513 display string and the previous row comes from the same string and
9514 is empty. (Bug#9739) (Bug#9738)
9516 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9518 * doc.c (get_doc_string): Encode file name (bug#9735).
9520 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9522 * bidi.c (bidi_level_of_next_char):
9523 * xdisp.c (get_visually_first_element): Remove old incorrect
9524 comments regarding the Unicode Line Separator character.
9526 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9528 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9530 * alloc.c (Fgc_status): Do not access beyond zombies array
9531 boundary if nzombies > MAX_ZOMBIES.
9532 * alloc.c (dump_zombies): Add missing format specifier.
9534 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9536 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9537 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9539 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9540 Some packages use them to denote characters with modifiers.
9542 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9544 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9545 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9546 matching a pp-number. Rename parameter var to var1.
9548 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9550 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9552 2011-10-08 Glenn Morris <rgm@gnu.org>
9554 * callint.c (Fcall_interactively): Give a more explicit error for the
9555 'c' case with a non-character input. (Bug#8479)
9557 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9559 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9561 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9562 lines that are hscrolled on the left.
9564 * dispnew.c (buffer_posn_from_coords): Account for a possible
9565 presence of header-line. (Bug#4426)
9567 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
9569 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
9570 Don't advertise functionality which we discourage or doesn't work.
9572 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
9574 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
9575 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
9576 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
9577 this makes Emacs dump core during garbage collection on rare
9578 occasions. sizeof is obviously inferior to offsetof here, so
9579 stick with offsetof.
9580 (GC_POINTER_ALIGNMENT): New macro.
9581 (mark_memory): Omit 3rd (offset) arg; caller changed.
9582 Don't assume EMACS_INT alignment is the same as pointer alignment.
9584 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
9586 * keyboard.c (read_key_sequence_remapped): New var.
9587 (read_key_sequence): Compute remapping in the right buffer.
9588 (command_loop_1): Use read_key_sequence's remapping directly.
9590 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
9592 * dired.c (file_name_completion): Don't expand file name.
9593 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
9594 before checking file name handler.
9596 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
9597 they've been requested explicitly (bug#9591).
9599 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
9601 * keymap.c (Fsingle_key_description): Use make_specified_string
9602 instead of build_string to build string from push_key_description.
9605 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9607 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
9608 This fixes a Y2038 bug on 64-bit hosts.
9609 * buffer.c (reset_buffer):
9610 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
9611 (Fclear_buffer_auto_save_failure):
9612 Use 0, not -1, to represent an unset failure time, since time_t
9613 might not be signed.
9615 Remove dependency on glibc malloc internals.
9616 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9617 Move back here from lisp.h, but with their new implementations.
9618 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9619 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
9620 * charset.c (charset_table_init): New static var.
9621 (syms_of_charset): Use it instead of xmalloc. This removes a
9622 dependency on glibc malloc internals. See Eli Zaretskii's comment in
9623 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
9624 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9625 Move back to alloc.c.
9626 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9627 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
9629 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
9631 * nsterm.m (windowDidResize): Call x_set_window_size only when
9632 ns_in_resize is true. Otherwise set pixelwidth/height and
9633 call change_frame_size (Bug#9628).
9635 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9637 Port --enable-checking=all to Fedora 14 x86-64.
9638 * charset.c (syms_of_charset): Also account for glibc malloc's
9639 internal overhead when calculating the initial malloc maximum.
9641 Port --enable-checking=all to Fedora 14 x86.
9642 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9644 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
9645 (overrun_check_realloc, overrun_check_free):
9646 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
9647 That way, xmalloc returns a properly-aligned pointer even if
9648 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
9649 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
9650 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
9651 into account when calculating the initial malloc maximum.
9652 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9653 Move here from alloc.c, so that charset.c can use it too.
9654 Properly align; the old code wasn't right for common 32-bit hosts
9655 when configured with --enable-checking=all.
9656 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9657 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
9659 2011-09-29 Eli Zaretskii <eliz@gnu.org>
9661 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
9664 2011-09-28 Eli Zaretskii <eliz@gnu.org>
9666 * xdisp.c (compute_display_string_end): If there's no display
9667 string at CHARPOS, return -1.
9669 * bidi.c (bidi_fetch_char): When compute_display_string_end
9670 returns a negative value, treat the character as a normal
9671 character not covered by a display string. (Bug#9624)
9673 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
9675 * lread.c (Fread_from_string): Fix typo in docstring.
9677 2011-09-27 Eli Zaretskii <eliz@gnu.org>
9679 * xdisp.c (handle_invisible_prop): If invisible text ends on a
9680 newline, reseat the iterator instead of bidi-iterating there one
9681 character at a time. (Bug#9610)
9682 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
9683 TO_CHARPOS if the bidi iterator is at base embedding level.
9685 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
9687 * lread.c (readevalloop): Use correct code for NBSP.
9688 (read1): Likewise. (Bug#9608)
9690 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
9692 * dbusbind.c (Fdbus_register_signal): When service is not
9693 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
9695 2011-09-25 Glenn Morris <rgm@gnu.org>
9697 * buffer.c (truncate-lines): Doc fix.
9699 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
9701 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
9702 (Fset_window_next_buffers): Doc fix.
9704 2011-09-24 Glenn Morris <rgm@gnu.org>
9706 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
9708 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
9710 Fix minor problems found by static checking.
9711 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
9712 * indent.c (Fvertical_motion): Fix == vs = typo.
9714 2011-09-24 Eli Zaretskii <eliz@gnu.org>
9716 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
9717 Default value is now t. Doc fix.
9719 * indent.c (Fvertical_motion): Compute and apply the overshoot
9720 logic when moving up, not only when moving down. Fix the
9721 confusing name and values of the it_overshoot_expected variable;
9722 logic changes accordingly. (Bug#9254) (Bug#9549)
9724 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
9725 CHARPOS is covered by a display string which includes newlines.
9726 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
9727 is covered by a display string with embedded newlines.
9729 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
9731 * dbusbind.c (Fdbus_register_signal): Add match rule to
9732 Vdbus_registered_objects_table. (Bug#9581)
9733 (Fdbus_register_method, Vdbus_registered_objects_table):
9736 2011-09-24 Jim Meyering <meyering@redhat.com>
9738 do not ignore write error for any output size
9739 The previous change was incomplete.
9740 While it makes emacs --batch detect the vast majority of stdout
9741 write failures, errors were still ignored whenever the output size is
9742 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
9743 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
9744 && echo FAIL: ignored write error
9745 FAIL: ignored write error
9746 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
9747 && echo FAIL: ignored write error
9748 FAIL: ignored write error
9749 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
9751 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
9753 * emacs.c (Fkill_emacs): In noninteractive mode exit
9754 non-successfully if a write error occurred on stdout. (Bug#9574)
9756 2011-09-21 Eli Zaretskii <eliz@gnu.org>
9758 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
9761 * dispextern.h (struct it): Update the comment documenting what
9764 2011-09-20 Eli Zaretskii <eliz@gnu.org>
9766 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
9767 a display string, extend search for cursor position to end of row.
9768 (find_row_edges): If the row ends in a newline from a display
9769 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
9770 Handle the case of a display string with multiple newlines.
9771 (Fcurrent_bidi_paragraph_direction): Fix search for previous
9772 non-empty line. Fixes confusing cursor motion with arrow keys at
9773 the beginning of a line that starts with whitespace.
9775 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9777 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
9780 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
9782 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
9785 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9787 * xdisp.c (display_line): Record maximum and minimum buffer
9788 positions even if no glyphs were produced (e.g., by a zero-width
9789 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
9790 buffer positions that will be removed from the glyph row because
9792 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
9793 column is beyond frame width: don't subtract 1 "pixel" when
9794 computing width of the stretch.
9795 (reseat_at_next_visible_line_start): Undo the change made on
9796 2011-09-17 that saved paragraph information and restored it after
9797 the call to `reseat'. (Bug#9545)
9799 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9801 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
9802 and turn window cursor on if cleared (Bug#9415).
9804 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
9806 * search.c (boyer_moore): Take unibyte characters from pattern
9807 literally. (Bug#9458)

9811 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
9813 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
9815 Fix minor problem found by static checking.
9816 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
9817 initialized, to pacify gcc -Wuninitialized.
9819 * fileio.c: Report proper errno when syscall falls.
9820 (Finsert_file_contents): Save and restore errno,
9821 so that report_file_error outputs the correct diagnostic.
9822 (Fwrite_region) [CLASH_DETECTION]: Likewise.
9824 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9826 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
9828 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9830 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
9831 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
9833 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9835 * xdisp.c (reseat_at_next_visible_line_start): Keep information
9836 about the current paragraph and restore it after the call to reseat.
9838 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
9839 (bidi_find_paragraph_start): Search back for paragraph beginning
9840 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
9841 (bidi_move_to_visually_next): Only trigger paragraph-related
9842 computations when the last character is a newline or at EOB, not
9843 just any NEUTRAL_B. (Bug#9470)
9845 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
9846 truncated lines if point is covered by a display string. (Bug#9524)
9848 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
9850 * xselect.c: Relax test for outgoing X longs (Bug#9498).
9851 (cons_to_x_long): New function.
9852 (lisp_data_to_selection_data): Use it. Correct the test for
9853 short-versus-long data; it was negated. Break out of vector
9854 loop, for efficiency, when a long datum is discovered.
9856 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
9858 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
9860 2011-09-16 Eli Zaretskii <eliz@gnu.org>
9862 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
9863 GCC PR/17406) by declaring this function with external scope.
9865 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9867 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
9868 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
9870 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
9872 * editfns.c (Fformat): Correctly handle text properties on "%%".

9882 of TAB characters in a composition.
9884 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9886 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
9887 This occurs when processing a multibyte format.
9888 Problem reported by Wolfgang Jenker.
9890 2011-09-15 Johan Bockgård <bojohan@gnu.org>
9892 * xdisp.c (try_cursor_movement): Only check for exact match if
9893 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
9895 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9897 Remove unused external symbols.
9898 * dispextern.h (calc_pixel_width_or_height): Remove decl.
9899 * xdisp.c (calc_pixel_width_or_height): Now static.
9900 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
9901 * indent.c (check_display_width):
9902 * w32term.c: Fix comment to match code.
9903 * xterm.c, xterm.h (x_catching_errors): Remove.
9905 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9907 * xselect.c: Use signed conversions more consistently (Bug#9498).
9908 (selection_data_to_lisp_data): Assume incoming selection data are
9909 signed integers, not unsigned. This is to be consistent with
9910 outgoing selection data, which was modified to use signed integers
9911 in as part of the fix to Bug#9196 in response to Jan D.'s comment
9912 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
9913 expects long, not unsigned long.

9917 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
9918 computation of loop end. Reported by Johan Bockgård
9921 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
9923 * frame.c (Fother_visible_frames_p): Function deleted.
9925 2011-09-12 Eli Zaretskii <eliz@gnu.org>
9927 * indent.c (compute_motion): Process display vector front to back
9928 rather than the other way around. (Bug#2496)
9930 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
9932 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
9934 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
9936 * minibuf.c (Fread_from_minibuffer): Doc fix.
9938 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9940 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
9941 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
9943 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
9945 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
9946 value for non-existent files.
9948 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9950 * fileio.c (Finsert_file_contents): If the file cannot be opened,
9951 set its "size" to -1. This will set the modtime_size field of
9952 the corresponding buffer to -1, which is what
9953 verify-visited-file-modtime expects for files that do not exist.
9956 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
9958 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
9960 * lisp.h: ... from here. push_key_description is no longer
9961 defined in keyboard.c, so its declaration should not be in
9962 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
9963 logically belongs with push_key_description.
9965 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
9967 * buffer.h: Include <sys/types.h> instead of <time.h>.
9968 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
9969 Problem reported by Herbert J. Skuhra.
9971 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
9973 * xml.c (parse_region): Make the parsing work for
9974 non-comment-starting XML files again (bug#9144).
9976 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
9978 * image.c (gif_load): Fix calculation of bottom and right corner.
9981 2011-09-10 Eli Zaretskii <eliz@gnu.org>
9983 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
9984 redisplay in small windows.
9986 2011-09-09 Eli Zaretskii <eliz@gnu.org>
9988 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
9990 2011-09-08 Martin Rudalics <rudalics@gmx.at>
9992 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
9993 Operate on live windows only.
9995 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
9997 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
9999 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10001 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10002 only under bidi iteration.
10004 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10006 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10008 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10010 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10011 Without this fix, the command to link temacs failed due to an
10012 undefined symbol __builtin_isnan. This is because
10013 /usr/include/iso/math_c99.h #defines isnan(x) to
10014 __builtin_isnan(x), but the bundled gcc, which identifies itself
10015 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10017 * floatfns.c (isnan): #undef, and then #define to a clone of
10019 (Fisnan): Always define, since it's always available now.
10020 (syms_of_floatfns): Always define isnan at the Lisp level.
10022 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10024 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10026 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10028 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10029 The previous code assumed that file offsets (off_t values) fit in
10030 EMACS_INT variables, which is not true on typical 32-bit hosts.
10031 The code messed up by falsely reporting buffer overflow in cases
10032 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10033 when "big" contains more than 2**29 bytes, even though this
10034 inserts just one byte and does not overflow the buffer.
10035 (Finsert_file_contents): Store file offsets as off_t
10036 values, not as EMACS_INT values. Check for overflow when
10037 converting between EMACS_INT and off_t. When checking for
10038 buffer overflow or for overlap, take the offsets into account.
10039 Don't use EMACS_INT for small values where int suffices.
10040 When checking for overlap, fix a typo: ZV was used where
10041 ZV_BYTE was intended.
10042 (Fwrite_region): Don't assume off_t fits into 'long'.
10043 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10045 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10047 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10049 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10051 sprintf-related integer and memory overflow issues (Bug#9412).
10053 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10054 (esprintf, exprintf, evxprintf): New functions.
10055 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10056 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10057 (modify_event_symbol): Do not assume that the length of
10058 name_alist_or_stem is safe to alloca and fits in int.
10059 (Fexecute_extended_command): Likewise for function name and binding.
10060 (Frecursion_depth): Wrap around reliably on integer overflow.
10061 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10062 since some callers pass EMACS_INT values.
10063 (Fsingle_key_description): Don't crash if symbol name contains more
10064 than MAX_ALLOCA bytes.
10065 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10066 (get_minibuffer): Arg is now EMACS_INT, not int.
10067 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10068 (esprintf, exprintf, evxprintf): New decls.
10069 * window.h (command_loop_level, minibuf_level): Reflect API changes.
10071 * dbusbind.c (signature_cat): New function.
10072 (xd_signature, Fdbus_register_signal):
10073 Do not overrun buffer; instead, report string overflow.
10075 * dispnew.c (add_window_display_history): Don't overrun buffer.
10076 Truncate instead; this is OK since it's just a log.
10078 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10079 even if the time zone offset is outlandishly large.
10080 Don't mishandle offset == INT_MIN.
10082 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10083 when creating daemon; the previous buffer-overflow check was incorrect.
10085 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10086 which has the guts of the old verror function.
10088 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10089 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10091 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10092 (font_unparse_xlfd): Don't blindly alloca long strings.
10093 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10094 fits in int, when using sprintf. Use single snprintf to count
10095 length of string rather than counting it via multiple sprintfs;
10096 that's simpler and more reliable.
10097 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10098 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10099 sprintf, in case result does not fit in int.
10101 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10102 (fontset_from_font): Print it.
10104 * frame.c (tty_frame_count): Now printmax_t, not int.
10105 (make_terminal_frame, set_term_frame_name): Print it.
10106 (x_report_frame_params): In X, window IDs are unsigned long,
10107 not signed long, so print them as unsigned.
10108 (validate_x_resource_name): Check for implausibly long names,
10109 and don't assume name length fits in 'int'.
10110 (x_get_resource_string): Don't blindly alloca invocation name;
10111 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10114 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10115 (xg_check_special_colors, xg_set_geometry):
10116 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10118 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10119 Use esprintf, not sprintf, in case result does not fit in int.
10121 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10122 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10123 it as a large positive number.
10124 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10125 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10127 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10128 in case result does not fit in int.
10130 * print.c (float_to_string): Detect width overflow more reliably.
10131 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10132 buffer overrun. Don't assume list length fits in 'int'. Treat
10133 print length of 0 as 0, not as infinity; to be consistent with other
10134 uses of print length in this function. Don't overflow print length
10135 index. Don't assume hash table size fits in 'long', or that
10136 vectorlike size fits in 'unsigned long'.
10138 * process.c (make_process): Use printmax_t, not int, to format
10139 process-name gensyms.
10141 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10143 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10144 to avoid potential buffer overrun.
10146 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10147 if X resource line is longer than 512 bytes.
10149 * xfns.c (x_window): Make sprintf buffer a bit bigger
10150 to avoid potential buffer overrun.
10152 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10154 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10156 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10158 Integer overflow fixes for scrolling, etc.
10159 Without these, Emacs silently mishandles large integers sometimes.
10160 For example, "C-u 4294967297 M-x recenter" was treated as if
10161 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10163 * xdisp.c (try_window_id): Check Emacs fixnum range before
10164 converting to 'int'.
10166 * window.c (window_scroll_line_based, Frecenter):
10167 Check that an Emacs fixnum is in range before assigning it to 'int'.
10168 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10169 values converted from Emacs fixnums.
10170 (Frecenter): Don't wrap around a line count if it is out of 'int'
10171 range; instead, treat it as an extreme value.
10172 (Fset_window_configuration, compare_window_configurations):
10173 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10175 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10176 that can exceed INT_MAX. Check that EMACS_INT value is in range
10177 before assigning it to the (possibly-narrower) index.
10178 (match_limit): Don't assume that a fixnum can fit in 'int'.
10180 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10183 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10184 (Fvertical_motion): Don't wrap around LINES values that don't fit
10185 in 'int'. Instead, treat them as extreme values. This is good
10186 enough for windows, which can't have more than INT_MAX lines anyway.
10188 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10190 * Require libxml/parser.h to avoid compilation warning.
10192 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10194 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10195 since this reportedly can destroy thread storage.
10197 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10199 * syntax.c (find_defun_start): Update all cache variables if
10200 exiting early (Bug#9401).
10202 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10204 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10206 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10207 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10208 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10210 * term.c (tty_append_glyph): New function.
10211 (produce_stretch_glyph): Static function and its prototype deleted.
10213 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10216 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10218 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10219 when checking :margin (Bug#9390).
10220 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10221 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10222 so that the name doesn't mislead. All uses changed.
10224 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10226 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
10229 2011-08-27 Eli Zaretskii <eliz@gnu.org>
10231 * xdisp.c (move_it_to): Don't bail out early when reaching
10232 position beyond to_charpos, if we are scanning backwards.
10233 (move_it_vertically_backward): When DY == 0, make sure we get to
10234 the first character in the line after the newline.
10236 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10238 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10239 (ccl_driver): Do not generate an out-of-range pointer.
10240 (Fccl_execute_on_string): Remove unnecessary check for
10241 integer overflow, noted by Stefan Monnier in
10242 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10243 Remove a FIXME that didn't need fixing.
10244 Simplify the newly-introduced buffer reallocation code.
10246 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10248 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10250 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10252 Integer and memory overflow issues (Bug#9196).
10254 * doc.c (get_doc_string): Rework so that
10255 get_doc_string_buffer_size is the actual buffer size, rather than
10256 being 1 less than the actual buffer size; this makes xpalloc more
10259 * image.c (x_allocate_bitmap_record, cache_image):
10260 * xselect.c (Fx_register_dnd_atom):
10261 Simplify previous changes by using xpalloc.
10263 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10264 since either will do and ptrdiff_t is convenient with xpalloc.
10266 * charset.c (charset_table_size)
10267 (struct charset_sort_data.priority): Now ptrdiff_t.
10268 (charset_compare): Don't overflow if priorities differ greatly.
10269 (Fsort_charsets): Don't assume list length fits in int.
10270 Check for size-calculation overflow when allocating sort data.
10271 (syms_of_charset): Allocate an initial charset table that is
10272 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10274 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10276 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10277 The actual value is always <= INT_MAX, and leaving it unsigned made
10278 overflow checking harder.
10280 * dispextern.h (struct glyph_matrix.rows_allocated)
10281 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10282 with xpalloc. The values are still always <= INT_MAX.
10284 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10286 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10287 (SAFE_NALLOCA): New macro.
10289 * region-cache.c (struct boundary.pos, find_cache_boundary)
10290 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10291 (set_cache_region, invalidate_region_cache)
10292 (revalidate_region_cache, know_region_cache, region_cache_forward)
10293 (region_cache_backward, pp_cache):
10294 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10295 so that ptrdiff_t * can be passed to xpalloc.
10296 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
10297 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
10298 (pp_cache): Don't assume cache_len fits in int.
10299 * region-cache.h: Adjust extern decls to match.
10301 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
10302 EMACS_INT, since either will do, for xpalloc.
10304 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
10305 (xnmalloc, xnrealloc, xpalloc): New functions.
10307 * bidi.c (bidi_shelve_header_size): New constant.
10308 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
10309 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
10311 * bidi.c (bidi_cache_shrink):
10312 * buffer.c (overlays_at, overlays_in, record_overlay_string)
10314 Don't update size of array until after memory allocation succeeds,
10315 because xmalloc/xrealloc may not return.
10316 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10317 now that we have proper integer overflow checking.
10318 (record_overlay_string, overlay_strings): Catch overflows when
10319 calculating size of overlay_str_buf.
10321 * callproc.c (Fcall_process): Check for size overflow when
10322 calculating size of args2.
10323 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
10324 Normally we prefer signed values, but sticking with ptrdiff_t would
10325 require adding more-complicated checks.
10327 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10328 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
10329 Redo buffer-overflow calculations to avoid integer overflow.
10330 Add a FIXME comment where memory seems to be over-allocated.
10332 * character.c (Fstring): Check for size-calculation overflow.
10334 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
10335 unnecessary integer overflow. Check for size overflow.
10336 (encode_coding_object): Don't update size until xmalloc succeeds.
10338 * composite.c (get_composition_id): Check for overflow in glyph
10339 length calculations.
10341 Integer and memory overflow fixes for display code.
10342 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
10343 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
10344 (scrolling_window): Check for overflow in size calculations.
10345 (line_draw_cost, realloc_glyph_pool, add_row_entry):
10346 Don't assume glyph table len fits in int.
10347 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
10348 (row_table_size): Now ptrdiff_t, not int.
10349 (scrolling_window): Avoid overflow in size calculations.
10350 Don't update size until allocation succeeds.
10351 * fns.c (concat): Check for overflow in size calculations.
10352 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
10353 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
10354 (NEXT_ALMOST_PRIME_LIMIT): New constant.
10356 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
10357 (get_doc_string): Check for size calculation overflow.
10358 Don't update size until allocation succeeds.
10359 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
10360 EMACS_INT, where ptrdiff_t will do.
10361 (Fsubstitute_command_keys): Check for string overflow.
10363 * editfns.c (set_time_zone_rule): Don't assume environment length
10365 (message_length): Now ptrdiff_t, not int.
10366 (Fmessage_box): Don't update size until allocation succeeds.
10367 Don't assume message length fits in int.
10368 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10370 * emacs.c (main): Do not reallocate argv, since there is a null at
10371 the end that can be overwritten, and this way there's no need to
10372 worry about size-calculation overflow.
10373 (sort_args): Check for size-calculation overflow.
10375 * eval.c (init_eval_once, grow_specpdl): Don't update size until

10381 Check for integer overflow.
10382 (x_set_alpha): Do not assume XINT fits in int.
10384 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10385 This is for the members text_lines, text_cols, total_lines, total_cols,
10386 where the system imposes an 'int' limit.

10395 Check for size-calculation overflow.
10396 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10397 do, as we prefer signed integers.

10453 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
10454 for command line length. Do not attempt to address one before the
10455 beginning of an array, as that's not portable.
10457 * term.c (max_frame_lines): Remove; unused.

10484 (Finternal_make_lisp_face, cache_face):
10485 Check for size calculation overflow.
10486 (cache_face): Treat size calculation overflows as if they were
10487 memory exhaustion (the usual treatment), rather than aborting.
10489 * xfns.c (x_encode_text, x_set_name_internal)
10490 (Fx_change_window_property): Use ptrdiff_t, not int, to count
10491 sizes, since they can exceed INT_MAX in size. Check for size
10492 calculation overflow.

10495 (xg_select): Check for size calculation overflow.
10496 Don't update size until alloc done.
10498 * xrdb.c (get_environ_db): Don't assume path length fits in int,
10499 as sprintf is limited to int lengths.
10501 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
10502 (X_LONG_MIN): New macros.
10503 Use them to make the following changes clearer.
10504 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
10505 This change doesn't affect the value now, but it may help remind
10506 future maintainers not to raise the value too much later.
10507 (SELECTION_QUANTUM): Remove, replacing with ...
10508 (selection_quantum): ... new function, which avoids overflow.
10510 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10511 assumption that selection length fits in 'int'.
10512 (x_reply_selection_request, x_handle_selection_request)
10513 (x_get_window_property, receive_incremental_selection)

10519 Redo calculations to avoid overflow.
10520 (x_reply_selection_request): When sending hint, ceiling it at

10524 (lisp_data_to_selection_data, x_property_data_to_lisp):
10525 Check for size-calculation overflow.

10528 Don't store size until memory allocation succeeds.
10529 (x_get_window_property): Plug memory leak on memory exhaustion.
10530 Don't double-block input; malloc is safe here. Don't assume 2**34
10531 - 4 fits in unsigned long. Add an xassert to check
10532 XGetWindowProperty overflow. Be more careful about overflow
10533 calculations, and distinguish size from memory overflow better.
10534 (receive_incremental_selection): When tracing, don't assume
10535 unsigned int is less than INT_MAX.
10536 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

10538 (lisp_data_to_selection_data): Don't assume that integers
10539 in the range -65535 through -1 fit in an X unsigned short.
10540 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10541 result parameters unless successful. Rely on cons_to_unsigned
10542 to report problems with elements; the old code wasn't right anyway.
10543 (x_check_property_data): Check for int overflow; we cannot use
10544 a wider type due to X limits.
10545 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

10577 * lisp.h (hash_lookup, hash_put):
10578 * minibuf.c (Ftest_completion):
10579 Use ptrdiff_t for hash table indexes, not int (which is too
10580 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
10581 32-bit --with-wide-int hosts).
10583 * charset.c (Fdefine_charset_internal): Check for integer overflow.
10584 Add a FIXME comment about memory leaks.
10585 (syms_of_charset): Don't assume xmalloc returns.

10592 with outlandish widths.
10593 * character.h (sanitize_tab_width): Rename from sanitize_width,
10594 now that we have two such functions. All uses changed.

10612 * xterm.c: Don't go over XClientMessageEvent limit.
10613 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
10614 (x_send_scroll_bar_event): Likewise. Check that the size does not
10615 exceed limits imposed by XClientMessageEvent, as well as the usual
10616 ptrdiff_t and size_t limits.
10618 * keyboard.c: Overflow, signedness and related fixes.
10619 (make_lispy_movement): Use same integer type in forward decl
10620 that is used in the definition.
10621 (read_key_sequence, keyremap_step):
10622 Change bufsize argument back to int, undoing my 2011-03-30 change.
10623 We prefer signed types, and int is wide enough here.
10624 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
10625 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
10626 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
10627 length, not size_t. Use ptrdiff_t for index, not int.
10628 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
10629 possibility of integer overflow.
10631 Overflow, signedness and related fixes for images.

10657 Prefer int to unsigned where either will do.
10658 (tiff_handler): New function, combining the cores of the
10659 old tiff_error_handler and tiff_warning_handler.
10660 This function is rewritten to use vsnprintf and thereby avoid
10661 stack buffer overflows. It uses only the features of vsnprintf
10662 that are common to both POSIX and native Microsoft.
10663 (tiff_error_handler, tiff_warning_handler): Use it.
10664 (tiff_load, gif_load, imagemagick_load_image):
10665 Don't assume :index value fits in 'int'.
10666 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
10667 (imagemagick_load_image): Check that crop parameters fit into
10668 the integer types that MagickCropImage accepts. Don't assume
10669 Vimagemagick_render_type has a nonnegative value. Don't assume
10670 size_t fits in 'long'.
10671 (gs_load): Use printmax_t to print the widest integers possible.

10684 handle_single_display_spec, not just 1 or zero.
10685 (handle_single_display_spec): If the display spec is of the form
10686 `(space ...)', and specifies display in the text area, return 2
10688 (try_cursor_movement): Check for the need to scroll more
10689 accurately, and prefer exact match for point under bidi.
10690 Don't advance `row' beyond the last row of the window.

10708 buffers, return left-to-right.
10709 (set_cursor_from_row): Consider candidate row a win if its glyph
10710 represents a newline and point is on that newline. Fixes cursor
10711 positioning on the newline at EOL of R2L text within L2R
10712 paragraph, and vice versa.
10713 (try_cursor_movement): Check continued rows, in addition to
10714 continuation rows. Fixes unwarranted scroll when point enters a
10715 continued line of R2L text within an L2R paragraph, or vice versa.
10716 (cursor_row_p): Consider the case of point being equal to
10717 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
10718 from the end of a short line to the beginning of a continued line
10719 of R2L text within L2R paragraph.
10720 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

10743 * xdisp.c (redisplay_window): When computing centering_position,
10744 account for the height of the header line. (Bug#8874)
10746 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
10747 instead of CHAR_TO_BYTE. Fixes a crash when a completion
10748 candidate is selected by the mouse, and that candidate has a
10749 composed character under the mouse.
10751 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
10752 coordinates reported by pos-visible-in-window-p for a composed
10753 character in column zero.
10755 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

10759 2011-08-22 Eli Zaretskii <eliz@gnu.org>
10761 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
10762 consider it a hit if to_charpos is anywhere in the range of the
10763 composed buffer positions.
10765 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
10767 * image.c (gif_load): Don't assume that each subimage has the same
10768 dimensions as the base image. Handle disposal method that is
10769 "undefined" by the gif spec (Bug#9335).
10771 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
10773 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

10778 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
10779 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
10780 from an Org mode buffer to a Speedbar frame.
10782 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
10783 a composition, take its buffer position from IT->cmp_it.charpos.
10784 Fixes cursor positioning at the beginning of a line that begins
10785 with a composed character.
10787 2011-08-18 Eli Zaretskii <eliz@gnu.org>
10789 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
10790 character bidirectional type, use STRONG_L instead. Fixes crashes
10791 in a buffer produced by `describe-categories'.
10793 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
10794 members before the level stack, so they would be saved and
10795 restored when copying iterator state. Fixes incorrect reordering
10796 around TABs covered by display properties.
10798 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
10800 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

10804 * eval.c (internal_condition_case, internal_condition_case_1)
10805 (internal_condition_case_2, internal_condition_case_n):
10806 Remove unnecessary aborts (Bug#9081).
10808 2011-08-17 Eli Zaretskii <eliz@gnu.org>
10810 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
10811 has no `load' handler, try opening the file locally. (Bug#9311)
10813 2011-08-16 Ken Brown <kbrown@cornell.edu>
10815 * gmalloc.c: Expand comment.
10817 2011-08-16 Eli Zaretskii <eliz@gnu.org>
10819 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
10820 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
10822 2011-08-16 Ken Brown <kbrown@cornell.edu>
10824 Fix memory allocation problems in Cygwin build (Bug#9273).
10826 * unexcw.c ( __malloc_initialized): Declare external variable.

10829 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
10831 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
10833 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
10834 in the static heap.
10835 [CYGWIN] (special_realloc): New function.
10836 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
10837 requests to realloc storage in the static heap.

10848 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
10850 * dispextern.h: Fix a typo in the comment to bidi_type_t.
10852 * chartab.c: Improve commentary for the uniprop_table API.
10854 * bidi.c (bidi_paragraph_init): Support zero value of
10855 bidi_ignore_explicit_marks_for_paragraph_level.
10856 (bidi_initialize): Use uniprop_table instead of including
10857 biditype.h and bidimirror.h.
10859 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
10860 coordinates of the iterator when restoring from ppos_it.
10863 2011-08-14 Kenichi Handa <handa@m17n.org>
10865 * process.c (create_process): Call setup_process_coding_systems
10866 after the pid of the process is set to -1 (Bug#8162).
10868 2011-08-14 Eli Zaretskii <eliz@gnu.org>
10870 * xdisp.c (move_it_in_display_line_to): Don't invoke
10871 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
10872 ppos_it. Fixes vertical cursor motion when line beginning is
10873 covered by an image. (Bug#9296)
10875 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
10877 * nsterm.h (ns_run_ascript): Declare.
10878 (NSAPP_DATA2_RUNASSCRIPT): Define.
10880 * nsfns.m (as_script, as_result, as_status): New static variables.
10881 (ns_run_ascript): New function.
10882 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
10883 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
10884 the event loop. Get status from as_status (Bug#7276).
10886 * nsterm.m (sendEvent): If event is NSApplicationDefined and
10887 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
10888 the event loop (Bug#7276).
10890 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
10892 * gnutls.c (QCgnutls_bootprop_priority)
10893 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
10894 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
10895 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
10896 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
10897 (QCgnutls_bootprop_verify_hostname_error)
10898 (QCgnutls_bootprop_callbacks_verify): Rename from
10899 Qgnutls_bootprop_..., all uses changed.
10901 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
10904 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
10906 * xfaces.c (Qframe_set_background_mode): Now static.

10911 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
10913 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
10914 (Fnetwork_interface_list): Allocate in increments of bytes instead
10915 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
10916 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
10918 (struct ifflag_def): notrailers is smart on OSX.
10919 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
10920 Get hardware address with getifaddrs if available.
10922 2011-08-12 Eli Zaretskii <eliz@gnu.org>
10924 * xdisp.c (iterate_out_of_display_property): xassert that
10925 IT->position is set to within IT->object's boundaries. Break from
10926 the loop as soon as EOB is reached; avoids infloops in redisplay
10927 when IT->position is set up wrongly due to some bug.
10928 Set IT->current to match the bidi iterator unconditionally.
10929 (push_display_prop): Allow GET_FROM_STRING as IT->method on
10930 entry. Force push_it to save on the stack the current
10931 buffer/string position, to be restored by pop_it. Fix flags in
10932 the iterator structure wrt the object coming from a display
10933 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
10934 properties. (Bug#9284)
10936 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
10938 * fontset.c (fontset_get_font_group): Add proper type checks.
10941 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

10944 and LC_VERSION_MIN_MACOSX.
10945 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
10946 (dump_it) [LC_FUNCTION_STARTS]: Use it.
10948 2011-08-08 Eli Zaretskii <eliz@gnu.org>
10950 * xdisp.c (forward_to_next_line_start): Allow to use the
10951 no-display-properties-and-no-overlays under bidi display.
10952 Set disp_pos in the bidi iterator to avoid searches for display
10953 properties and overlays.
10955 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
10957 * editfns.c (Fset_time_zone_rule): Document relationship with the

10961 the font entity extracted from the cache (Bug#8109).
10963 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
10965 * composite.c (autocmp_chars): Don't reset point. That is done by
10966 restore_point_unwind (Bug#5984).
10968 2011-08-07 Juri Linkov <juri@jurta.org>
10970 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
10971 to show the arg `TIME' instead of `TIMEVAL'.
10973 2011-08-06 Eli Zaretskii <eliz@gnu.org>
10975 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
10976 display property strides EOL and includes a newline, as in
10977 longlines-mode. (Bug#9254)
10978 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
10979 word-wrap under bidirectional display. (Bug#9224)
10981 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
10982 is non-zero, even if the data buffer is NULL. Fixes a crash in
10983 vertical-motion with longlines-mode. (Bug#9254)
10985 2011-08-05 Eli Zaretskii <eliz@gnu.org>
10987 * bidi.c <bidi_cache_total_alloc>: Now static.
10988 (bidi_initialize): Initialize bidi_cache_total_alloc.
10990 * xdisp.c (display_line): Release buffer allocated for shelved bidi
10993 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
10994 amount allocated this far in `bidi_cache_total_alloc'.
10995 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
10996 non-zero, only free the data buffer without restoring the cache
10997 contents. All callers changed.
10999 * dispextern.h (bidi_unshelve_cache): Update prototype.
11001 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
11002 (move_it_in_display_line, move_it_to)
11003 (move_it_vertically_backward, move_it_by_lines): Replace the call
11004 to xfree to an equivalent call to bidi_unshelve_cache.
11005 (move_it_in_display_line_to): Fix logic of returning
11006 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
11008 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11010 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
11011 came from a string character with a `cursor' property. (Bug#9229)
11013 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11015 * Makefile.in (LIB_PTHREAD): New variable.
11016 (LIBES): Add LIB_PTHREAD (Bug#9216).
11018 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
11019 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
11021 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
11023 * regex.c (re_iswctype): Remove some redundant boolean conversions.
11025 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11027 * xterm.c (x_find_topmost_parent): New function.
11028 (x_set_frame_alpha): Find topmost parent window with
11029 x_find_topmost_parent and set the property there also (bug#9181).
11030 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
11032 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
11034 * callproc.c (Fcall_process): Avoid vfork clobbering
11035 the local vars buffer, coding_systems, current_dir.
11037 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
11039 * keymap.c (Fmake_composed_keymap): Move to subr.el.
11041 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
11043 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
11044 so that it is not optimized away.
11046 * xdisp.c (compute_display_string_pos): Remove unused local.
11048 2011-08-02 Eli Zaretskii <eliz@gnu.org>
11050 Fix slow cursor motion and scrolling in large buffers with
11051 selective display, like Org Mode buffers. (Bug#9218)
11053 * dispextern.h (struct bidi_it): New member disp_prop_p.
11055 * xdisp.c: Remove one-slot cache of display string positions.
11056 (compute_display_string_pos): Accept an additional argument
11057 DISP_PROP_P; callers changed. Scan at most 5K characters forward
11058 for a display string or property. If found, set DISP_PROP_P
11061 * bidi.c (bidi_fetch_char): Accept an additional argument
11062 DISP_PROP_P, and pass it to compute_display_string_pos.
11063 Only handle text covered by a display string if DISP_PROP_P is returned
11064 non-zero. All callers of bidi_fetch_char changed.
11066 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
11068 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
11070 2010-12-03 Don March <don@ohspite.net>
11072 * keymap.c (Fdefine_key): Fix non-prefix key error message when
11073 last character M-[char] is translated to ESC [char] (bug#7541).
11075 2011-08-02 Kenichi Handa <handa@m17n.org>
11077 * lisp.h (uniprop_table): Extern it.
11079 * chartab.c (uniprop_table): Make it non-static.
11081 2011-08-01 Eli Zaretskii <eliz@gnu.org>
11083 * xdisp.c (forward_to_next_line_start): Accept additional argument
11084 BIDI_IT_PREV, and store into it the state of the bidi iterator had
11086 (reseat_at_next_visible_line_start): Use the bidi iterator state
11087 returned by forward_to_next_line_start to restore the state of
11088 it->bidi_it after backing up to previous newline. (Bug#9212)
11090 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
11092 * regex.c (re_comp): Protoize.
11093 (re_exec): Fix return type.
11094 (regexec): Fix type of `ret'. (Bug#9203)
11096 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11098 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
11099 This is needed if max-image-size is a floating-point number.
11101 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11103 * print.c (print_object): Print empty symbol as ##.
11105 * lread.c (read1): Read ## as empty symbol.
11107 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11109 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
11110 setting frame foreground color (Bug#9175).
11111 (x_set_background_color): Likewise.
11113 * nsmenu.m (-setText): Size tooltip dimensions precisely to
11114 contents (Bug#9176).
11115 (EmacsTooltip -init): Remove bezels and add shadows to
11118 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
11119 or scroll bar (Bug#8470).
11121 * nsfont.m (nsfont_open): Remove assignment to voffset and
11122 unnecessary vars hshink, expand, hd, full_height, min_height.
11123 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
11125 * nsterm.h (nsfont_info): Remove voffset field.
11127 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11129 Implement strike-through and overline on NextStep (Bug#8863).
11131 * nsfont.m (nsfont_open): Use underline position provided by font,
11132 instead of hard-coded value of 2.
11133 (nsfont_draw): Call ns_draw_text_decoration instead.
11135 * nsterm.h: Add declaration for ns_draw_text_decoration.
11137 * nsterm.m (ns_draw_text_decoration): New function for drawing
11138 underline, overline, and strike-through.
11139 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
11140 ns_draw_text_decoration. Change treatment of cursor drawing to
11141 accommodate underlining, etc.
11143 2011-07-28 Eli Zaretskii <eliz@gnu.org>
11145 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
11148 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11150 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11151 Without this fix, if a signal arrives just after memory fills up,
11152 'malloc' might be invoked reentrantly.
11154 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11155 In other words, assume that every image size is allowed, on non-X
11156 hosts. This assumption is probably wrong, but it lets Emacs compile.
11158 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11160 * regex.c (re_iswctype): Convert return values to boolean.
11162 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
11164 * xdisp.c (compute_display_string_pos): Don't use cached display
11165 string position if the buffer had its restriction changed.
11168 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11170 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11172 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11174 Integer signedness and overflow and related fixes. (Bug#9079)
11176 * bidi.c: Integer size and overflow fixes.
11177 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
11178 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
11179 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11180 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11181 (bidi_find_other_level_edge):
11182 Use ptrdiff_t instead of EMACS_INT where either will do.
11183 This works better on 32-bit hosts configured --with-wide-int.
11184 (bidi_cache_ensure_space): Check for size-calculation overflow.
11185 Use % rather than repeated addition, for better worst-case speed.
11186 Don't set bidi_cache_size until after xrealloc returns, because it
11188 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11189 (bidi_cache_ensure_space): Also check that the bidi cache size
11190 does not exceed that of the largest Lisp string or buffer. See Eli
11191 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11193 * alloc.c (__malloc_size_t): Remove.
11194 All uses replaced by size_t. See Andreas Schwab's note
11195 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11197 * image.c: Improve checking for integer overflow.
11198 (check_image_size): Assume that f is nonnull, since
11199 it is always nonnull in practice. This is one less thing to
11200 worry about when checking for integer overflow later.
11201 (x_check_image_size): New function, which checks for integer
11202 overflow issues inside X.
11203 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11204 This removes the need for a memory_full check.
11205 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11206 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11207 (xbm_read_bitmap_data): Change locals back to 'int', since
11208 their values must fit in 'int'.
11209 (xpm_load_image, png_load, tiff_load):
11210 Invoke x_create_x_image_and_pixmap earlier,
11211 to avoid much needless work if the image is too large.
11212 (tiff_load): Treat overly large images as if
11213 x_create_x_image_and_pixmap failed, not as malloc failures.
11214 (gs_load): Use x_check_image_size.
11216 * gtkutil.c: Omit integer casts.
11217 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11218 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11220 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11222 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11223 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11224 would wrongly return t on a 64-bit host.
11226 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11227 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11228 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11229 and therefore cause GCC to emit a bogus diagnostic in some cases.
11231 * image.c: Integer signedness and overflow and related fixes.
11232 This is not an exhaustive set of fixes, but it's time to
11233 record what I've got.
11234 (lookup_pixel_color, check_image_size): Remove redundant decls.
11235 (check_image_size): Don't assume that arbitrary EMACS_INT values
11236 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11237 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11238 (tiff_load, imagemagick_load_image):
11239 Check for overflow in size calculations.
11240 (x_create_x_image_and_pixmap): Remove unnecessary test for
11241 xmalloc returning NULL; that can't happen.
11242 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11243 (xpm_color_bucket): Use better integer hashing function.
11244 (xpm_cache_color): Don't possibly over-allocate memory.
11245 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11246 (gif_memory_source):
11247 Use ptrdiff_t, not int or size_t, to record sizes.
11248 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11249 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11250 either works, as we prefer signed integers.
11251 (tiff_read_from_memory, tiff_write_from_memory):
11252 Return tsize_t, not size_t, since that's what the TIFF API wants.
11253 (tiff_read_from_memory): Don't fail simply because the read would
11254 go past EOF; instead, return a short read.
11255 (tiff_load): Omit no-longer-needed casts.
11256 (Fimagemagick_types): Don't assume size fits into 'int'.
11258 Improve hashing quality when configured --with-wide-int.
11259 * fns.c (hash_string): New function, taken from sxhash_string.
11260 Do not discard information about ASCII character case; this
11261 discarding is no longer needed.
11262 (sxhash-string): Use it. Change sig to match it. Caller changed.
11263 * lisp.h: Declare it.
11264 * lread.c (hash_string): Remove, since we now use fns.c's version.
11265 The fns.c version returns a wider integer if --with-wide-int is
11266 specified, so this should help the quality of the hashing a bit.
11268 * emacs.c: Integer overflow minor fix.
11269 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11270 Define only if GNU_LINUX.
11271 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11273 * dispnew.c: Integer signedness and overflow fixes.
11274 Remove unnecessary forward decls, that were a maintenance hassle.
11275 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11277 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11278 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11279 (prepare_desired_row, line_draw_cost):
11280 Use int, not unsigned, where either works.
11281 (save_current_matrix, restore_current_matrix):
11282 Use ptrdiff_t, not size_t, where either works.
11283 (init_display): Check for overflow more accurately, and without
11284 relying on undefined behavior.
11286 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11287 Remove, replacing with the new symbols in lisp.h. All uses changed.
11288 * fileio.c (make_temp_name):
11289 * filelock.c (lock_file_1, lock_file):
11290 * xdisp.c (message_dolog):
11291 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11292 Use pMd etc. instead.
11293 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11294 replacing the pWIDE etc. symbols removed from editfns.c.
11296 * keyboard.h (num_input_events): Now uintmax_t.
11297 This is (very slightly) less likely to mess up due to wraparound.
11300 * buffer.c: Integer signedness fixes.
11301 (alloc_buffer_text, enlarge_buffer_text):
11302 Use ptrdiff_t rather than size_t when either will do, as we prefer
11305 * alloc.c: Integer signedness and overflow fixes.
11306 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11307 (__malloc_size_t): Default to size_t, not to int.
11308 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11309 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11310 Prefer ptrdiff_t to size_t when either would do, as we prefer
11312 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11313 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11314 Now const. Initialize with values that are in range even if char
11316 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11317 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11318 These functions do the right thing with sizes > 2**32.
11319 (check_depth): Now ptrdiff_t, not int.
11320 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11321 Adjust to new way of storing sizes. Check for size overflow bugs
11323 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11324 slightly wrong anyway, as it missed one instance of
11325 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11326 (refill_memory_reserve): Omit needless cast to size_t.
11327 (mark_object_loop_halt): Mark as externally visible.
11329 * xselect.c: Integer signedness and overflow fixes.
11330 (Fx_register_dnd_atom, x_handle_dnd_message):
11331 Use ptrdiff_t, not size_t, since we prefer signed.
11332 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11333 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11334 x_dnd_atoms_size and x_dnd_atoms_length.
11336 * doprnt.c: Prefer signed to unsigned when either works.
11338 * doprnt.c (doprnt):
11340 * xdisp.c (vmessage):
11341 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11342 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11343 prefer signed arithmetic to avoid comparison confusion.
11344 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11345 but is a bit tricky.
11347 Assume freestanding C89 headers, string.h, stdlib.h.
11348 * data.c, doprnt.c, floatfns.c, print.c:
11349 Include float.h unconditionally.
11350 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11351 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11352 * regex.c: Likewise for stddef.h, string.h.
11353 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11354 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11355 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11356 (STDC_HEADERS): Remove obsolete defines.
11357 * sysdep.c: Include limits.h unconditionally.
11359 Assume support for memcmp, memcpy, memmove, memset.
11360 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11361 * regex.c (memcmp, memcpy):
11362 Remove; we assume C89 now.
11364 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11365 (__malloc_safe_bcopy): Remove; no longer needed.
11367 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11368 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11369 well either way, and we prefer signed to unsigned.
11371 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11373 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11374 closes the connection while we're reading (bug#9182).
11376 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11378 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11379 are specified (Bug#9168).
11381 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11383 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11384 Found by GCC static checking and --with-wide-int on a 32-bit host.
11386 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11388 * xdisp.c (compute_display_string_pos): Fix logic of caching
11389 previous display string position. Initialize cached_prev_pos to
11390 -1. Fixes slow-down at the beginning of a buffer.
11392 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11394 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11395 for attrs[LFACE_FONTSET_INDEX].
11397 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11399 * xml.c (parse_region): Remove unused local
11400 that was recently introduced.
11402 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11404 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11405 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11407 * xdisp.c (move_it_in_display_line_to): Record the best matching
11408 position for TO_CHARPOS while scanning the line, and restore it on
11409 exit if none of the characters scanned was an exact match.
11410 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11411 when exact match is impossible due to invisible text, and the
11412 lines are truncated.
11414 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11416 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11419 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11421 Fix a significant slow-down of cursor motion with C-n, C-p,
11422 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11423 auto-repeat under bidi redisplay in fontified buffers.
11424 * xdisp.c (compute_stop_pos_backwards): New function.
11425 (next_element_from_buffer): Call compute_stop_pos_backwards to
11426 find a suitable prev_stop when we find ourselves before
11428 (reseat): Don't look for prev_stop, as that could mean a very long
11430 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11431 <cached_disp_overlay_modiff>: Cache for last found display string
11433 (compute_display_string_pos): Return the cached position if asked
11434 about the same buffer in the same area of character positions, and
11435 the buffer wasn't changed since the time the display string
11436 position was cached.
11438 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11440 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11441 is an integer, which is important for empty lines. (Bug#9149)
11443 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11445 * frame.c (Fmodify_frame_parameters): In tty case, update the
11446 default face if necessary (Bug#4238).
11448 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11450 * editfns.c (Fstring_to_char): No need to explain what a character
11451 is in the docstring (Bug#6576).
11453 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11455 * xml.c (parse_region): Make sure we always return a tree.
11457 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11459 * xml.c (parse_region): If a document contains only comments,
11462 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11464 * xml.c (make_dom): Return comments, too.
11466 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11469 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11470 and the surrounding thread.
11471 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11472 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11473 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11475 * s/openbsd.h (BROKEN_SIGIO): Define.
11476 * unexelf.c (unexec) [__OpenBSD__]:
11477 Don't update the .mdebug section of the Alpha COFF symbol table.
11479 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11481 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11484 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11486 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11487 This fixes some race conditions on the permissions of any newly
11490 * alloc.c (valid_pointer_p): Use pipe, not open.
11491 This fixes some permissions issues when debugging.
11493 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11494 If fchown fails to set both uid and gid, try to set just gid,
11495 as that is sometimes allowed. Adjust the file's mode to eliminate
11496 setuid or setgid bits that are inappropriate if fchown fails.
11498 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11500 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11501 to compare Lisp_Objects.
11502 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11503 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11504 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11506 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11508 * lread.c (read_integer): Unread even EOF character.
11509 (read1): Likewise. Properly record start position of symbol.
11511 * lread.c (read1): Read `#:' as empty uninterned symbol if no
11512 symbol character follows.
11514 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11516 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11517 This works around a problem with the previous change to Fcopy_file.
11518 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11519 and without this change, GCC might complain about discarding
11520 fchown's return value.
11522 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11524 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11526 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11528 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11530 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11532 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11533 it's used from the C level.
11535 * process.c: Use the same condition for POLL_FOR_INPUT in both
11536 keyboard.c and process.c (bug#1858).
11538 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11540 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11541 (Fgnutls_boot): Use it.
11543 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11545 * doc.c (Fsubstitute_command_keys): Revert last change.
11547 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11549 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11550 quotes the next character, and doesn't affect other longer
11551 sequences (bug#8935).
11553 * lread.c (syms_of_lread): Clarify that is isn't only
11554 `eval-buffer' and `eval-defun' that's affected by
11555 `lexical-binding' (bug#8460).
11557 2011-07-15 Eli Zaretskii <eliz@gnu.org>
11559 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11560 bidi redisplay when a line includes both an image and is truncated.
11562 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11564 Fix minor problems found by static checking.
11565 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11566 (elsz): Now a signed constant, not a size_t var. We prefer signed
11567 types to unsigned, to avoid integer comparison confusion. Without
11568 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
11569 "cannot optimize loop, the loop counter may overflow", a symptom
11571 * indent.c (Fvertical_motion): Mark locals as initialized.
11572 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
11574 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
11576 * search.c (Fre_search_backward): Mention `case-fold-search' in
11577 all the re_search_* functions (bug#8138).
11579 * keyboard.c (Fopen_dribble_file): Document when the file is

11590 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
11591 (reseat_to_string): Initialize bidi_it->string.s and
11592 bidi_it->string.schars.
11593 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
11594 NULL (avoids a crash in bidi_paragraph_init).
11595 Initialize itb.string.lstring.
11596 (init_iterator): Call bidi_init_it only of a valid
11597 buffer position was specified. Initialize paragraph_embedding to
11599 (reseat_to_string): Initialize the bidi iterator.
11600 (display_string): If we need to ignore text properties of
11601 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
11602 original value of -1 will not work with bidi.)
11603 (compute_display_string_pos): First arg is now struct
11604 `text_pos *'; all callers changed. Support display properties on
11606 (compute_display_string_end): Support display properties on Lisp
11608 (init_iterator, reseat_1, reseat_to_string): Initialize the
11609 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
11610 when iterating on a string not from display properties).
11611 (compute_display_string_pos, compute_display_string_end):
11612 Fix calculation of the object to scan. Fixes an error when using
11614 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
11615 base_level_stop; instead, set base_level_stop to BEGV.
11616 Fixes crashes in vertical-motion.
11617 (next_element_from_buffer): Improve commentary for when
11618 the iterator is before prev_stop.
11619 (init_iterator): Initialize bidi_p from the default value of
11620 bidi-display-reordering, not from buffer-local value. Use the
11621 buffer-local value only if initializing for buffer iteration.
11622 (handle_invisible_prop): Support invisible properties on strings
11623 that are being bidi-reordered.
11624 (set_iterator_to_next): Support bidi reordering of C strings and
11626 (next_element_from_string): Support bidi reordering of Lisp
11628 (handle_stop_backwards): Support Lisp strings as well.
11629 (display_string): Support display of R2L glyph rows.
11630 Use IT_STRING_CHARPOS when displaying from a Lisp string.
11631 (init_iterator): Don't initialize it->bidi_p for strings
11633 (reseat_to_string): Initialize it->bidi_p for strings here.
11634 (next_element_from_string, next_element_from_c_string)
11635 (next_element_from_buffer): Add xassert's for correspondence
11636 between IT's object being iterated and it->bidi_it.string
11638 (face_before_or_after_it_pos): Support bidi iteration.
11639 (next_element_from_c_string): Handle the case of the first string
11640 character that is not the first one in the visual order.
11641 (get_visually_first_element): New function, refactored from common
11642 parts of next_element_from_buffer, next_element_from_string, and
11643 next_element_from_c_string.
11644 (tool_bar_lines_needed, redisplay_tool_bar)
11645 (display_menu_bar): Force left-to-right direction. Add a FIXME
11646 comment for making that be controlled by a user option.
11647 (push_it, pop_it): Save and restore the state of the
11648 bidi iterator. Save and restore the bidi_p flag.
11649 (pop_it): Iterate out of display property for string iteration as
11651 (iterate_out_of_display_property): Support iteration over strings.
11652 (handle_single_display_spec): Set up it->bidi_it for iteration
11653 over a display string, and call bidi_init_it.
11654 (handle_single_display_spec, next_overlay_string)
11655 (get_overlay_strings_1, push_display_prop): Set up the bidi
11656 iterator for displaying display or overlay strings.
11657 (forward_to_next_line_start): Don't use the shortcut if
11659 (back_to_previous_visible_line_start): If handle_display_prop
11660 pushed the iterator stack, restore the internal state of the bidi
11661 iterator by calling bidi_pop_it same number of times.
11662 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
11663 and we are bidi-iterating, don't decrement the iterator position;
11664 instead, set the first_elt flag in the bidi iterator, to produce
11666 (reseat_1): Remove redundant setting of string_from_display_prop_p.
11667 (push_display_prop): xassert that we are iterating a buffer.
11668 (push_it, pop_it): Save and restore paragraph_embedding member.
11669 (handle_single_display_spec, next_overlay_string)
11670 (get_overlay_strings_1, reseat_1, reseat_to_string)
11671 (push_display_prop): Set up the `unibyte' member of bidi_it.string
11672 correctly. Don't assume unibyte strings are not bidi-reordered.
11673 (compute_display_string_pos)
11674 (compute_display_string_end): Fix handling the case of C string.
11675 (push_it, pop_it): Save and restore from_disp_prop_p.
11676 (handle_single_display_spec, push_display_prop): Set the
11677 from_disp_prop_p flag.
11678 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
11679 (pop_it): Call iterate_out_of_display_property only if we are
11680 popping after iteration over a string that came from a display
11681 property. Fix a typo in popping stretch info. Add an assertion
11682 for verifying that the iterator position is in sync with the bidi
11684 (handle_single_display_spec, get_overlay_strings_1)
11685 (push_display_prop): Fix initialization of paragraph direction for
11686 string when that of the parent object is not yet determined.
11687 (reseat_1): Call bidi_init_it to resync the bidi
11688 iterator with IT's position. (Bug#7616)
11689 (find_row_edges): If ROW->start.pos gives position
11690 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
11691 (handle_stop, back_to_previous_visible_line_start, reseat_1):
11692 Reset the from_disp_prop_p flag.
11693 (SAVE_IT, RESTORE_IT): New macros.
11694 (pos_visible_p, face_before_or_after_it_pos)
11695 (back_to_previous_visible_line_start)
11696 (move_it_in_display_line_to, move_it_in_display_line)

12135 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
12137 Random fixes. E.g., (random) never returned negative values.
12138 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
12139 subseconds part to the entropy, as that's a bit more random.
12140 Prefer signed to unsigned, since the signedness doesn't matter and
12141 in general we prefer signed. When given a limit, use a
12142 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12143 latter isn't right if USE_2_TAGS_FOR_INTS.
12144 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12145 not 0..VALMASK. Don't discard "excess" bits that random () returns.
12147 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
12149 * textprop.c (text_property_stickiness):
12150 Obey Vtext_property_default_nonsticky.

12157 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
12158 This is more efficient than Ffile_directory_p and avoids a minor race.
12160 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
12162 * buffer.c (Foverlay_put): Say what the return value is
12165 * fileio.c (barf_or_query_if_file_exists): Check first if the file
12166 is a directory before asking whether to use the file name
12168 (barf_or_query_if_file_exists): Make the "File is a directory"
12169 error be more correct.
12171 * fns.c (Frequire): Remove the mention of the .gz files, since
12172 that's installation-specific, but keep the mention of
12173 `get-load-suffixes'.
12175 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
12177 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

12180 2011-07-04 Juanma Barranquero <lekktu@gmail.com>
12182 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
12183 (syms_of_gnutls): Remove duplicate DEFSYM for
12184 Qgnutls_bootprop_verify_hostname_error, an error for
12185 Qgnutls_bootprop_verify_error (which is no longer used).
12187 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
12188 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
12189 Also (re)move comments that are misplaced or no longer relevant.
12191 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12193 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

12197 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
12198 and background color parameters if they have been changed.

12218 * lread.c (syms_of_lread): Mention single symbols defined by
12219 `defvar' or `defconst' (bug#7154).
12221 * fns.c (Frequire): Mention .el.gz files (bug#7314).
12222 (Frequire): Mention get-load-suffixes.
12224 2011-07-02 Martin Rudalics <rudalics@gmx.at>

12252 (syms_of_keymap): Defsubr make-composed-keymap.
12253 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

12290 * eval.c (struct backtrace): Simplify and port the data structure.
12291 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12292 signed bit field, as this assumption is not portable and it makes
12293 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12294 "char debug_on_exit : 1" as this is not portable either; instead,
12295 use the portable "unsigned int debug_on_exit : 1". Remove unused
12296 member evalargs. Remove obsolete comments about cc bombing out.
12298 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
12300 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

12366 (emacs_fixed_new): Set priv->f to argument.
12367 (emacs_fixed_get_preferred_width)
12368 (emacs_fixed_get_preferred_height): Use min_width/height from
12369 frames size_hint to set minimum and natural (Bug#8919).
12370 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
12371 and use min_width/height from frames size_hint to set
12372 min_width/height (Bug#8919).

12464 * print.c (printchar, strout): Check for string overflow.
12465 (PRINTPREPARE, printchar, strout):
12466 Don't set size unless allocation succeeds.
12468 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
12469 for sizes. Check for string overflow more accurately.

12483 (read_integer): Radix is now EMACS_INT, not int,
12484 to improve quality of diagnostics for out-of-range radices.
12485 Calculate buffer size correctly for out-of-range radices.
12486 (read1): Check for integer overflow in radices, and in
12487 read-circle numbers.
12488 (read_escape): Avoid int overflow.
12489 (Fload, openp, read_buffer_size, read1)
12490 (substitute_object_recurse, read_vector, read_list, map_obarray):
12491 Use ptrdiff_t, not int, for sizes.

12513 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
12514 The following patches are for when GLYPH_DEBUG && !XASSERT.
12515 * dispextern.h (trace_redisplay_p, dump_glyph_string):
12516 * dispnew.c (flush_stdout):
12517 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
12518 Mark as externally visible.
12519 * dispnew.c (check_window_matrix_pointers): Now static.
12520 * dispnew.c (window_to_frame_vpos):
12521 * xfns.c (unwind_create_frame):

12528 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
12530 (debug_method_add): Use va_list and vsprintf rather than relying
12531 on undefined behavior with wrong number of arguments.
12532 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12533 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12534 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12535 since we're not interested in debugging glyphs with old libraries.
12536 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12537 GCC 4.6.0's static checking.
12539 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

12573 Use ptrdiff_t, not int, for sizes.
12574 (overlays_at, overlays_in): Check for size-calculation overflow.
12576 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
12578 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
12579 (x_session_initialize): Do not assume string length fits in int.
12581 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
12582 This is unlikely, but can occur if DPI is outlandish.
12584 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
12585 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
12587 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
12588 * xrdb.c (magic_file_p, search_magic_path):
12589 Omit last arg SUFFIX; it was always 0. All callers changed.
12590 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
12592 * xfont.c (xfont_match): Avoid need for strlen.
12594 * xfns.c: Don't assume strlen fits in int.
12595 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
12597 * xdisp.c (message_log_check_duplicate): Return intmax_t,
12598 not unsigned long, as we prefer signed integers. All callers changed.
12599 Detect integer overflow in repeat count.
12600 (message_dolog): Don't assume print length fits in 39 bytes.
12601 (display_mode_element): Don't assume strlen fits in int.
12603 * termcap.c: Don't assume sizes fit in int and never overflow.
12604 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
12605 (gobble_line): Check for size-calculation overflow.
12607 * minibuf.c (Fread_buffer):
12608 * lread.c (intern, intern_c_string):
12609 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
12610 Don't assume string length fits in int.
12612 * keyboard.c (parse_tool_bar_item):
12613 * gtkutil.c (style_changed_cb): Avoid need for strlen.
12615 * font.c: Don't assume string length fits in int.
12616 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
12617 Use ptrdiff_t, not int.
12618 (font_intern_prop): Don't assume string length fits in int.
12619 Don't assume integer property fits in fixnum.
12620 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
12622 * filelock.c: Fix some buffer overrun and integer overflow issues.
12623 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
12624 Reformulate so as not to need the command string.
12625 Invoke gzip -cd rather than gunzip, as it's more portable.
12626 (lock_info_type, lock_file_1, lock_file):
12627 Don't assume pid_t and time_t fit in unsigned long.
12628 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
12629 (current_lock_owner): Prefer signed type for sizes.
12630 Use memcpy, not strncpy, where memcpy is what is really wanted.
12631 Don't assume (via atoi) that time_t and pid_t fit in int.
12632 Check for time_t and/or pid_t out of range, e.g., via a network share.
12633 Don't alloca where an auto var works fine.
12635 * fileio.c: Fix some integer overflow issues.
12636 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
12637 Don't assume string length fits in int.
12638 (directory_file_name): Don't assume string length fits in long.
12639 (make_temp_name): Don't assume pid fits in int, or that its print
12640 length is less than 20.
12642 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
12644 * coding.c (make_subsidiaries): Don't assume string length fits in int.
12646 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
12648 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
12649 We prefer signed integers, even for size calculations.
12651 * emacs.c: Don't assume string length fits in 'int'.
12652 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
12653 (main): Don't invoke strlen when not needed.
12655 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
12656 (XD_DEBUG_MESSAGE): Don't waste a byte.
12658 * callproc.c (getenv_internal_1, getenv_internal)
12659 (Fgetenv_internal):
12660 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
12662 * lread.c (invalid_syntax): Omit length argument.
12663 All uses changed. This doesn't fix a bug, but it simplifies the
12664 code away from its former Hollerith-constant appearance, and it's
12665 one less 'int' to worry about when looking at integer-overflow issues.
12666 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
12668 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
12669 This didn't break anything, but it didn't help either.
12670 It's confusing to put a bogus integer in a place where the actual
12671 value does not matter.
12672 (LIST_END_P): Remove unused macro and its bogus comment.
12673 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
12675 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
12676 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
12678 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
12679 We prefer signed types, and the value cannot exceed the EMACS_INT
12680 range anyway (because otherwise the length would not be representable).
12681 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
12682 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
12683 This avoids a GCC warning when WIDE_EMACS_INT.
12685 * indent.c (sane_tab_width): New function.
12686 (current_column, scan_for_column, Findent_to, position_indentation)
12687 (compute_motion): Use it. This is just for clarity.
12688 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
12690 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
12692 * lisp.h (lint_assume): New macro.
12693 * composite.c (composition_gstring_put_cache):
12694 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
12696 * editfns.c, insdel.c:
12697 Omit unnecessary forward decls, to simplify future changes.
12699 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
12701 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
12703 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
12704 Use much-faster test for byte-length change.
12705 Don't assume string byte-length fits in 'int'.
12706 Check that character arg fits in 'int'.
12707 (mapcar1): Declare byte as byte, for clarity.
12709 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
12711 * fns.c (concat): Catch string overflow earlier.
12712 Do not rely on integer wraparound.
12714 * dispextern.h (struct it.overlay_strings_charpos)
12715 (struct it.selective): Now EMACS_INT, not int.
12716 * xdisp.c (forward_to_next_line_start)
12717 (back_to_previous_visible_line_start)
12718 (reseat_at_next_visible_line_start, next_element_from_buffer):
12719 Don't arbitrarily truncate the value of 'selective' to int.
12721 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
12723 * composite.c: Don't truncate sizes to 'int'.
12724 (composition_gstring_p, composition_reseat_it)
12725 (composition_adjust_point): Use EMACS_INT, not int.
12726 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
12727 not EMACS_UINT, for indexes.
12729 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
12731 * buffer.c: Include <verify.h>.
12732 (struct sortvec.priority, struct sortstr.priority):
12733 Now EMACS_INT, not int.
12734 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
12735 (struct sortstr.size, record_overlay_string)
12736 (struct sortstrlist.size, struct sortlist.used):
12737 Don't truncate size to int.
12738 (record_overlay_string): Check for size-calculation overflow.
12739 (init_buffer_once): Check at compile-time, not run-time.
12741 2011-06-22 Jim Meyering <meyering@redhat.com>
12743 Don't leak an XBM-image-sized buffer
12744 * image.c (xbm_load): Free the image buffer after using it.
12746 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
12749 * composite.c (find_automatic_composition): Omit needless 'return 0;'
12750 that Sun C diagnosed.
12751 * fns.c (secure_hash): Fix pointer signedness issue.
12752 * intervals.c (static_offset_intervals): New function.
12753 (offset_intervals): Use it.
12755 2011-06-21 Leo Liu <sdl.web@gmail.com>
12758 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
12761 * fns.c (secure_hash): Rename from crypto_hash_function and change
12762 the first arg to accept symbols.
12763 (Fsecure_hash): New primitive.
12764 (syms_of_fns): New symbols.
12766 2011-06-20 Deniz Dogan <deniz@dogan.se>
12768 * process.c (Fset_process_buffer): Clarify return value in
12771 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
12773 * dispnew.c (add_window_display_history): Use BVAR.
12775 * xdisp.c (debug_method_add): Use BVAR.
12776 (check_window_end, dump_glyph_matrix, dump_glyph)
12777 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
12779 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
12782 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
12783 check till after the cache is created in init_frame_faces.
12785 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
12787 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
12789 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
12791 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
12792 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
12793 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
12795 Improve buffer-overflow checking (Bug#8873).
12796 * fileio.c (Finsert_file_contents):
12797 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
12798 Remove the old (too-loose) buffer overflow checks.
12799 They weren't needed, since make_gap checks for buffer overflow.
12800 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
12801 The old code merely checked for Emacs fixnum overflow, and relied
12802 on undefined (wraparound) behavior. The new code avoids undefined
12803 behavior, and also checks for ptrdiff_t and/or size_t overflow.
12805 * editfns.c (Finsert_char): Don't dump core with very negative counts.
12806 Tune. Don't use wider integers than needed. Don't use alloca.
12807 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
12809 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
12811 * insdel.c, lisp.h (buffer_overflow): New function.
12812 (insert_from_buffer_1, replace_range, replace_range_2):
12813 * insdel.c (make_gap_larger):
12814 * editfns.c (Finsert_char):
12815 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
12817 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
12819 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
12821 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
12823 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
12824 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
12826 * fileio.c: Don't assume EMACS_INT fits in off_t.
12827 (emacs_lseek): New static function.
12828 (Finsert_file_contents, Fwrite_region): Use it.
12829 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
12831 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
12833 * fns.c: Don't overflow int when computing a list length.
12834 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
12835 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
12836 truncation on 64-bit hosts. Check for QUIT every
12837 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
12838 faster and is responsive enough.
12839 (Flength): Report an error instead of overflowing an integer.
12840 (Fsafe_length): Return a float if the value is not representable
12841 as a fixnum. This shouldn't happen except in contrived situations.
12842 (Fnthcdr, Fsort): Don't assume list length fits in int.
12843 (Fcopy_sequence): Don't assume vector length fits in int.
12845 * alloc.c: Check that resized vectors' lengths fit in fixnums.
12846 (header_size, word_size): New constants.
12847 (allocate_vectorlike): Don't check size overflow here.
12848 (allocate_vector): Check it here instead, since this is the only
12849 caller of allocate_vectorlike that could cause overflow.
12850 Check that the new vector's length is representable as a fixnum.
12852 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
12853 The previous code was bogus. For example, next_almost_prime (32)
12854 returned 39, which is undesirable as it is a multiple of 3; and
12855 next_almost_prime (24) returned 25, which is a multiple of 5 so
12856 why was the code bothering to check for multiples of 7?
12858 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
12860 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
12862 Variadic C functions now count arguments with ptrdiff_t.
12863 This partly undoes my 2011-03-30 change, which replaced int with size_t.
12864 Back then I didn't know that the Emacs coding style prefers signed int.
12865 Also, in the meantime I found a few more instances where arguments
12866 were being counted with int, which may truncate counts on 64-bit
12867 machines, or EMACS_INT, which may be unnecessarily wide.
12868 * lisp.h (struct Lisp_Subr.function.aMANY)
12869 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
12870 Arg counts are now ptrdiff_t, not size_t.
12871 All variadic functions and their callers changed accordingly.
12872 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
12873 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
12874 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
12875 * callint.c (Fcall_interactively): Check arg count for overflow,
12876 to avoid potential buffer overrun. Use signed char, not 'int',
12877 for 'varies' array, so that we needn't bother to check its size
12878 calculation for overflow.
12879 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
12880 * eval.c (apply_lambda):
12881 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
12882 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
12883 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
12885 * callint.c (Fcall_interactively): Don't use index var as event count.
12887 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
12888 * mem-limits.h (SIZE): Remove; no longer used.
12890 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
12892 Remove unnecessary casts.
12893 * xterm.c (x_term_init):
12894 * xfns.c (x_set_border_pixel):
12895 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
12896 These aren't needed now that we assume ANSI C.
12898 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
12899 It's more likely to cause problems (due to unsigned overflow)
12902 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
12904 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
12906 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
12908 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
12910 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
12912 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
12914 GLYPH_CODE_FACE returns EMACS_INT, not int.
12915 * dispextern.h (merge_faces):
12916 * xfaces.c (merge_faces):
12917 * xdisp.c (get_next_display_element, next_element_from_display_vector):
12918 Don't assume EMACS_INT fits in int.
12920 * character.h (CHAR_VALID_P): Remove unused parameter.
12921 * fontset.c, lisp.h, xdisp.c: All uses changed.
12923 * editfns.c (Ftranslate_region_internal): Omit redundant test.
12925 * fns.c (concat): Minor tuning based on overflow analysis.
12926 This doesn't fix any bugs. Use int to hold character, instead
12927 of constantly refetching from Emacs object. Use XFASTINT, not
12928 XINT, for value known to be a character. Don't bother comparing
12929 a single byte to 0400, as it's always less.
12931 * floatfns.c (Fexpt):
12932 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
12934 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
12937 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
12939 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
12940 Without this fix, on a 64-bit host (aset S 0 4294967386) would
12941 incorrectly succeed when S was a string, because 4294967386 was
12942 truncated before it was used.
12944 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
12945 Otherwise, an out-of-range integer could cause undefined behavior
12948 * composite.c: Use int, not EMACS_INT, for characters.
12949 (fill_gstring_body, composition_compute_stop_pos): Use int, not
12950 EMACS_INT, for values that are known to be in character range.
12951 This doesn't fix any bugs but is the usual style inside Emacs and
12952 may generate better code on 32-bit machines.
12954 Make sure a 64-bit char is never passed to ENCODE_CHAR.
12955 This is for reasons similar to the recent CHAR_STRING fix.
12956 * charset.c (Fencode_char): Check that character arg is actually
12957 a character. Pass an int to ENCODE_CHAR.
12958 * charset.h (ENCODE_CHAR): Verify that the character argument is no
12959 wider than 'int', as a compile-time check to prevent future regressions
12962 * character.c (char_string): Remove unnecessary casts.
12964 Make sure a 64-bit char is never passed to CHAR_STRING.
12965 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
12966 by silently ignoring the top 32 bits, allowing some values
12967 that were far too large to be valid characters.
12968 * character.h: Include <verify.h>.
12969 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
12970 arguments are no wider than unsigned, as a compile-time check
12971 to prevent future regressions in this area.
12973 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
12974 (Fsubst_char_in_region):
12976 * xdisp.c (decode_mode_spec_coding):
12977 Adjust to CHAR_STRING's new requirement.
12978 * editfns.c (Finsert_char, Fsubst_char_in_region):
12979 * fns.c (concat): Check that character args are actually
12980 characters. Without this test, these functions did the wrong
12981 thing with wildly out-of-range values on 64-bit hosts.
12983 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
12984 These casts should not be needed on 32-bit hosts, either.
12985 * keyboard.c (read_char):
12986 * lread.c (Fload): Remove casts to unsigned.
12988 * lisp.h (UNSIGNED_CMP): New macro.
12989 This fixes comparison bugs on 64-bit hosts.
12990 (ASCII_CHAR_P): Use it.
12991 * casefiddle.c (casify_object):
12992 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
12993 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
12994 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
12995 * dispextern.h (FACE_FROM_ID):
12996 * keyboard.c (read_char): Use UNSIGNED_CMP.
12998 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
12999 not to EMACS_INT, to avoid GCC warning.
13001 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13003 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13004 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
13005 isn't needed on 32-bit machines.
13007 * buffer.c (Fgenerate_new_buffer_name):
13008 Use EMACS_INT for count, not int.
13009 (advance_to_char_boundary): Return EMACS_INT, not int.
13011 * data.c (Qcompiled_function): Now static.
13013 * window.c (window_body_lines): Now static.
13015 * image.c (gif_load): Rename local to avoid shadowing.
13017 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
13018 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.

13640 instead of using explicit *_CHAR codes.
13641 (bidi_resolve_explicit, bidi_resolve_weak):

13650 (bidi_level_of_next_char): Don't try to lookup the cache for the
13651 next/previous character if nothing is cached there yet, or if we
13652 were just reseat()'ed to a new position.
13654 * xdisp.c (set_cursor_from_row): Set start and stop points
13655 according to the row's direction when priming the loop that looks
13656 for the glyph on which to display cursor.

13658 (display_prop_intangible_p): Reimplement to call
13659 handle_display_spec instead of single_display_spec_intangible_p.
13660 Accept 3 additional arguments needed by handle_display_spec.
13661 This fixes incorrect cursor motion across display property with complex
13662 values: lists, `(when COND...)' forms, etc.

13664 lists with the argument STRING its top-level element.
13665 (display_prop_string_p): Fix the condition for processing a

13669 (compute_display_string_pos): Accept additional argument
13670 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
13671 value of a `display' property is a "replacing spec".
13672 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
13673 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
13674 the display property, but just return a value indicating whether
13675 the display property will replace the characters it covers.
13676 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
13677 frame_window_p members of struct bidi_it.
13678 (compute_display_string_pos, compute_display_string_end):

13701 All callers changed. (Bug#8762)
13703 * gnutls.c: Use Emacs's memory allocators.
13704 Without this change, the gnutls library would invoke malloc etc.
13705 directly, which causes problems on non-SYNC_INPUT hosts, and which
13706 runs afoul of improving memory_full behavior. (Bug#8761)
13707 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
13708 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
13709 xfree instead of the default malloc, realloc, free.
13710 (Fgnutls_boot): No need to check for memory allocation failure,
13711 since xmalloc does that for us.
13713 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

13733 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
13734 for hashes and hash indexes, instead of 'unsigned' and 'int'.
13735 * alloc.c (allocate_vectorlike):
13736 Check for overflow in vector size calculations.
13737 * ccl.c (ccl_driver):
13738 Check for overflow when converting EMACS_INT to int.

13740 need to be updated by these changes.
13741 * fns.c (make_hash_table, maybe_resize_hash_table):
13742 Check for integer overflow with large hash tables.
13743 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
13744 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
13745 (SXHASH_REDUCE): New macro.
13746 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
13747 Use it instead of discarding useful hash info with large hash values.
13748 (sxhash_float): New function.
13749 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
13750 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
13751 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
13752 Rewrite to use FIXNUM_BITS, as this simplifies things.
13753 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
13754 Adjust signatures to match updated version of code.
13755 (consing_since_gc): Now EMACS_INT, since a single hash table can
13756 use more than INT_MAX bytes.

13805 Make it possible to run ./temacs.
13807 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
13808 syms_of_callproc does the same thing. Remove test for

13869 * fns.c (to_uchar): Define.
13870 (crypto_hash_function): Use it to convert some newly-signed

13873 45723a2aff78ff4fff7fff1114760e62 rather than the expected
13874 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in

13885 (Fdbus_method_return_internal, Fdbus_method_error_internal):
13886 Check for serial numbers out of range. Decode any serial number
13887 that was so large that it became a float. (Bug#8722)
13889 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
13890 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13891 Use XFASTINT rather than XUINT when numbers are nonnegative.
13892 (xd_append_arg, Fdbus_method_return_internal):
13893 (Fdbus_method_error_internal): Likewise. Also, for unsigned
13894 arguments, check that Lisp number is nonnegative, rather than
13895 silently wrapping negative numbers around. (Bug#8722)
13896 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
13899 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
13901 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
13903 ccl: Add integer overflow checks.
13904 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
13905 (IN_INT_RANGE): New macros.
13906 (ccl_driver): Use them to check for integer overflow when
13907 decoding a CCL program. Many of the new checks are whether XINT (x)
13908 fits in int; it doesn't always, on 64-bit hosts. The new version
13909 doesn't catch all possible integer overflows, but it's an
13910 improvement. (Bug#8719)
13912 * alloc.c (make_event_array): Use XINT, not XUINT.
13913 There's no need for unsigned here.
13915 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
13916 This follows up to the 2011-05-06 change that substituted uintptr_t
13917 for EMACS_INT. This case wasn't caught back then.
13919 Rework Fformat to avoid integer overflow issues.
13920 * editfns.c: Include <float.h> unconditionally, as it's everywhere
13921 now (part of C89). Include <verify.h>.
13922 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
13923 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
13924 (Fformat): Avoid the prepass trying to compute sizes; it was only
13925 approximate and thus did not catch overflow reliably. Instead, walk
13926 through the format just once, formatting and computing sizes as we go,
13927 checking for integer overflow at every step, and allocating a larger
13928 buffer as needed. Keep track separately whether the format is
13929 multibyte. Keep only the most-recently calculated precision, rather
13930 than them all. Record whether each argument has been converted to
13931 string. Use EMACS_INT, not int, for byte and char and arg counts.
13932 Support field widths and precisions larger than INT_MAX. Avoid
13933 sprintf's undefined behavior with conversion specifications such as %#d
13934 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
13935 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
13936 formatting out-of-range floating point numbers with int
13937 formats. (Bug#8668)
13939 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
13941 * data.c: Avoid integer truncation in expressions involving floats.
13942 * data.c: Include <intprops.h>.
13943 (arith_driver): When there's an integer overflow in an expression
13944 involving floating point, convert the integers to floating point
13945 so that the resulting value does not suffer from catastrophic
13946 integer truncation. For example, on a 64-bit host (* 4
13947 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
13948 Do not rely on undefined behavior after integer overflow.
13950 merge count_size_as_multibyte, parse_str_to_multibyte
13951 * character.c, character.h (count_size_as_multibyte):
13952 Rename from parse_str_to_multibyte; all uses changed.
13953 Check for integer overflow.
13954 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
13955 since it's now a duplicate of the other. This is more of
13956 a character than a buffer op, so better that it's in character.c.
13957 * fns.c, print.c: Adjust to above changes.
13959 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
13961 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
13963 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13965 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13966 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
13967 (x_clipboard_manager_save): Now static.
13968 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
13970 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13971 (crypto_hash_function): Now static.
13972 Fix pointer signedness problems. Avoid unnecessary initializations.
13974 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
13976 * termhooks.h (Vselection_alist): Make it terminal-local.
13978 * terminal.c (create_terminal): Initialize it.
13980 * xselect.c: Support for clipboard managers.
13981 (Vselection_alist): Move to termhooks.h as terminal-local var.
13982 (LOCAL_SELECTION): New macro.
13983 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
13984 (symbol_to_x_atom): Remove gratuitous arg.
13985 (x_handle_selection_request, lisp_data_to_selection_data)
13986 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
13987 (x_own_selection, x_get_local_selection, x_convert_selection):
13988 New arg, specifying work frame. Use terminal-local Vselection_alist.
13989 (some_frame_on_display): Delete unused function.
13990 (Fx_own_selection_internal, Fx_get_selection_internal)
13991 (Fx_disown_selection_internal, Fx_selection_owner_p)
13992 (Fx_selection_exists_p): New optional frame arg.
13993 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
13994 (x_handle_selection_clear): Don't treat other terminals with the
13995 same keyboard specially. Use the terminal-local Vselection_alist.
13996 (x_clear_frame_selections): Use Frun_hook_with_args.
13998 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14000 * xterm.h: Add support for those atoms.
14002 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14004 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14005 (converted_selections, conversion_fail_tag): New global variables.
14006 (x_selection_request_lisp_error): Free the above.
14007 (x_get_local_selection): Remove unnecessary code.
14008 (x_reply_selection_request): Args changed; handle arbitrary array
14009 of converted selections stored in converted_selections.
14010 Separate the XChangeProperty and SelectionNotify steps.
14011 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14012 (x_convert_selection): New function.
14013 (x_handle_selection_event): Simplify.
14014 (x_get_foreign_selection): Don't ignore incoming requests while
14015 waiting for an answer; this will fail when we implement
14016 SAVE_TARGETS, and seems unnecessary anyway.
14017 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14018 (Vx_sent_selection_functions): Doc fix.
14020 2011-05-26 Leo Liu <sdl.web@gmail.com>
14022 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14024 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14026 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14028 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14029 for fringe update if it has periodic bitmap.
14030 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14031 and fringe_bitmap_periodic_p.
14033 * fringe.c (get_fringe_bitmap_data): New function.
14034 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14035 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14036 row. Mark glyph row for fringe update if periodicity changed.
14038 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14039 for fringe update unless it has periodic bitmap.
14041 2011-05-25 Kenichi Handa <handa@m17n.org>
14043 * xdisp.c (get_next_display_element): Set correct it->face_id for
14044 a static composition.
14046 2011-05-24 Leo Liu <sdl.web@gmail.com>
14049 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
14051 * fns.c (crypto_hash_function, Fsha1): New function.
14052 (Fmd5): Use crypto_hash_function.
14053 (syms_of_fns): Add Ssha1.
14055 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14057 * gnutls.c: Remove unused macros.
14058 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14059 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14060 Remove macros that are defined and never used.
14061 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14063 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14065 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14066 (Fx_get_selection_internal): Minor cleanup.
14067 (Fx_own_selection_internal): Rename arguments for consistency with
14070 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14072 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
14074 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14076 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
14078 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14080 * dispnew.c (scrolling_window): Don't exclude the case that the
14081 last enabled row in the desired matrix touches the bottom boundary.
14083 2011-05-21 Glenn Morris <rgm@gnu.org>
14085 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
14086 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
14087 and add some more files.
14089 2011-05-20 Eli Zaretskii <eliz@gnu.org>
14091 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
14092 report_file_error introduced by the change from 2011-05-07.
14094 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14096 * systime.h (Time): Define only if emacs is defined.
14097 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14098 where the include path doesn't have X11/X.h by default. See
14099 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14101 2011-05-20 Kenichi Handa <handa@m17n.org>
14103 * composite.c (find_automatic_composition): Fix previous change.
14105 2011-05-20 Glenn Morris <rgm@gnu.org>
14107 * lisp.mk: New file, split from Makefile.in.
14108 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14109 (shortlisp): Remove.
14110 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14112 2011-05-19 Glenn Morris <rgm@gnu.org>
14114 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14115 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14116 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14117 (lisp): Set the order to that of loadup.el.
14118 (shortlisp): Make it a copy of $lisp.
14119 (SOME_MACHINE_LISP): Remove.
14120 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14121 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14123 2011-05-18 Kenichi Handa <handa@m17n.org>
14125 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14126 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14127 (find_automatic_composition): Mostly rewrite for efficiency.
14129 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14131 * makefile.w32-in: Update dependencies.
14133 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14135 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14136 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14138 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14140 Fix some integer overflow issues, such as string length overflow.
14142 * insdel.c (count_size_as_multibyte): Check for string overflow.
14144 * character.c (lisp_string_width): Check for string overflow.
14145 Use EMACS_INT, not int, for string indexes and lengths; in
14146 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14147 the resulting string length overflows an EMACS_INT; instead,
14148 report a string overflow if no precision given. When checking for
14149 precision exhaustion, use a check that cannot possibly have
14150 integer overflow. (Bug#8675)
14151 * character.h (lisp_string_width): Adjust to new signature.
14153 * alloc.c (string_overflow): New function.
14154 (Fmake_string): Use it. This doesn't change behavior, but saves
14155 a few bytes and will simplify future changes.
14156 * character.c (string_escape_byte8): Likewise.
14157 * lisp.h (string_overflow): New decl.
14159 Fixups, following up to the user-interface timestamp change.
14160 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14161 for UI timestamps, instead of unsigned long.
14162 * msdos.c (mouse_get_pos): Likewise.
14163 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14164 * w32gui.h (Time): Define by including "systime.h" rather than by
14165 declaring it ourselves. (Bug#8664)
14167 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14168 * image.c (clear_image_cache): Likewise.
14170 * term.c (term_mouse_position): Don't assume time_t wraparound.
14172 Be more systematic about user-interface timestamps.
14173 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14174 and sometimes 'EMACS_UINT', to represent these timestamps.
14175 This change causes it to use 'Time' uniformly, as that's what X uses.
14176 This makes the code easier to follow, and makes it easier to catch
14177 integer overflow bugs such as Bug#8664.
14178 * frame.c (Fmouse_position, Fmouse_pixel_position):
14179 Use Time, not unsigned long, for user-interface timestamps.
14180 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14181 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14182 * keyboard.h (last_event_timestamp): Likewise.
14183 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14184 * menu.h (xmenu_show): Likewise.
14185 * term.c (term_mouse_position): Likewise.
14186 * termhooks.h (struct input_event.timestamp): Likewise.
14187 (struct terminal.mouse_position_hook): Likewise.
14188 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14189 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14190 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14191 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14192 what it was before.
14193 * menu.h, termhooks.h: Include "systime.h", for Time.
14195 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14196 Don't assume that the difference between two unsigned long values
14197 can fit into an integer. At this point, we know button_down_time
14198 <= event->timestamp, so the difference must be nonnegative, so
14199 there's no need to cast the result if double-click-time is
14200 nonnegative, as it should be; check that it's nonnegative, just in
14201 case. This bug is triggered when events are more than 2**31 ms
14202 apart (about 25 days). (Bug#8664)
14204 * xselect.c (last_event_timestamp): Remove duplicate decl.
14205 (x_own_selection): Remove needless cast to unsigned long.
14207 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14208 that always fit in int. Use a sentinel instead of a counter, to
14209 avoid a temp and to allay GCC's concerns about possible int overflow.
14210 * frame.h (struct frame): Use int for menu_bar_items_used
14211 instead of EMACS_INT, since it always fits in int.
14213 * menu.c (grow_menu_items): Check for int overflow.
14215 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14217 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14218 Before, the code was not consistent. These values cannot exceed
14219 2**31 - 1 so there's no need to make them unsigned.
14220 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14221 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14222 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14224 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14226 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14227 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14228 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14229 presumably because the widths might not match.
14231 * window.c (size_window): Avoid needless test at loop start.
14233 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14235 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14237 2011-05-12 Drew Adams <drew.adams@oracle.com>
14239 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14241 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14243 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14244 `width' to `bar_area_x' and `bar_area_width', respectively.
14245 (x_scroll_run): Take account of fringe background extension.
14247 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14248 Rename local vars `left' and `width' to `bar_area_x' and
14249 `bar_area_width', respectively.
14250 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14251 background extension.
14253 2011-05-10 Jim Meyering <meyering@redhat.com>
14255 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14257 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14259 * image.c (Finit_image_library): Return t for built-in image types,
14260 like pbm and xbm. (Bug#8640)
14262 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14264 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14266 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14268 * w32console.c (Fset_screen_color): Doc fix.
14269 (Fget_screen_color): New function.
14270 (syms_of_ntterm): Defsubr it.
14272 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14273 unlink the temporary file if Fcall_process didn't create it in the
14275 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14276 child process will be redirected to a file specified with `:file'.
14277 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14278 cue to call_process_cleanup not to close that handle.
14280 2011-05-07 Ben Key <bkey76@gmail.com>
14282 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14283 one of two shell specific rules, either bootstrap-temacs-CMD or
14284 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14285 to the previous implementation of the bootstrap-temacs rule.
14286 The bootstrap-temacs-CMD rule is similar to the previous
14287 implementation of the bootstrap-temacs rule except that it
14288 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14291 These changes, along with some changes to nt/configure.bat,
14292 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14293 earlier fix to add support for --cflags and --ldflags options
14294 that include quotes so that it works whether make uses cmd or
14297 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14299 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14300 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14302 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14303 a string. Handle both cases.
14304 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14305 (Fdbus_register_method): Use Qinvalid_function.
14307 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14309 * makefile.w32-in: Update dependencies.
14310 (LISP_H): Add inttypes.h and stdin.h.
14311 (PROCESS_H): Add unistd.h.
14313 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14315 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14316 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14318 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14320 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14322 * term.c (vfatal): Remove stray call to va_end.
14323 It's not needed and the C Standard doesn't allow it here anyway.
14325 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14326 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14328 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14331 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14333 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14335 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14337 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14339 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14341 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14342 * charset.c (Fdefine_charset_internal): Don't initialize
14343 charset.code_space[15]. The value was garbage, on hosts with
14344 32-bit int (Bug#8600).
14346 * lread.c (read_integer): Be more consistent with string-to-number.
14347 Use string_to_number to do the actual conversion; this avoids
14348 rounding errors and fixes some other screwups. Without this fix,
14349 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14350 (digit_to_number): Move earlier, for benefit of read_integer.
14351 Return -1 if the digit is out of range for the base, -2 if it is
14352 not a digit in any supported base. (Bug#8602)
14354 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14356 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14357 to match comment at start of function. This also removes a
14358 GCC warning about overflow in a 32+64-bit port.
14360 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14362 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14363 Reported by Stefan Monnier in
14364 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14365 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14366 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14368 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14369 (EMACS_UINTPTR): Likewise, with uintptr_t.
14371 * lisp.h: Prefer 64-bit EMACS_INT if available.
14372 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14373 on 32-bit hosts that have 64-bit int, so that they can access
14375 However, temporarily disable this change unless the temporary
14376 symbol WIDE_EMACS_INT is defined.
14378 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14380 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14381 This removes an assumption that EMACS_INT and long are the same
14382 width as pointers. The assumption is true for Emacs porting targets
14383 now, but we want to make other targets possible.
14384 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14385 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14386 In the rest of the code, change types of integers that hold casted
14387 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14388 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14389 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14390 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14391 No need to cast type when ORing.
14392 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14393 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14394 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14395 assume EMACS_INT is the same width as char *.
14396 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14397 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14398 Remove no-longer-needed casts.
14399 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14400 (xg_tool_bar_help_callback, xg_make_tool_item):
14401 Use EMACS_INTPTR to hold an integer
14402 that will be cast to void *; this can avoid a GCC warning
14403 if EMACS_INT is not the same width as void *.
14404 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14405 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14406 (current_message_1, set_message_1):
14407 Use a local to convert to proper width without a cast.
14408 * xmenu.c (dialog_selection_callback): Likewise.
14410 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14411 Also, don't assume VALBITS / RAND_BITS is less than 5,
14412 and don't rely on undefined behavior when shifting a 1 left into
14414 * lisp.h (get_random): Change signature to match.
14416 * lread.c (hash_string): Use size_t, not int, for hash computation.
14417 Normally we prefer signed values; but hashing is special, because
14418 it's better to use unsigned division on hash table sizes so that
14419 the remainder is nonnegative. Also, size_t is the natural width
14420 for hashing into memory. The previous code used 'int', which doesn't
14421 retain enough info to hash well into very large tables.
14422 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14424 * dbusbind.c: Don't possibly lose pointer info when converting.
14425 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14426 Use XPNTR rather than XHASH, so that the high-order bits of
14427 the pointer aren't lost when converting through void *.
14429 * eval.c (Fautoload): Don't double-shift a pointer.
14431 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14433 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14435 * gnutls.c (DEF_GNUTLS_FN):
14436 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14438 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14440 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14443 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14445 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14446 New version that can reserve upto 2GB of heap space.
14448 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14450 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14452 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14454 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14455 `gnutls_certificate_set_x509_key_file'.
14457 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
14459 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
14460 Update dependencies.
14462 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14464 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14465 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14466 Remove unused parameter `fildes'.
14467 * process.c (read_process_output, send_process): Don't pass it.
14469 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14471 Fix previous change: the library cache is defined in w32.c.
14472 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14473 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14475 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14477 Implement dynamic loading of GnuTLS on Windows.
14479 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14480 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14481 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14484 * gnutls.c (Qgnutls_dll): Define.
14485 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
14486 (gnutls_*): Declare function pointers.
14487 (init_gnutls_functions): New function to initialize function pointers.

14490 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14491 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
14492 (emacs_gnutls_write, emacs_gnutls_read)
14493 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14494 (Fgnutls_available_p): New function.
14495 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
14496 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
14497 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
14499 * image.c: Include w32.h.
14500 (Vimage_type_cache): Delete.
14501 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
14502 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
14503 (w32_delayed_load): Move to w32.c.
14505 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
14507 * w32.c (QCloaded_from, Vlibrary_cache): Define.
14508 (w32_delayed_load): Move from image.c. When loading a library, record
14509 its filename in the :loaded-from property of the library id.
14510 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
14511 Initialize and staticpro them.
14512 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
14514 * process.c: Include lisp.h before w32.h, not after.
14515 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
14516 instead of gnutls_record_check_pending.
14518 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
14520 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
14522 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
14523 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
14526 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
14528 * xterm.c (x_set_frame_alpha): Do not set property on anything
14529 else than FRAME_X_OUTER_WINDOW (Bug#8608).
14531 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14533 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
14535 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14537 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
14538 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

14551 * sysdep.c (wait_for_termination_1): Make static.
14552 (wait_for_termination, interruptible_wait_for_termination):
14553 Move after wait_for_termination_1.
14555 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
14557 * sysdep.c (interruptible_wait_for_termination): New function
14558 which is like wait_for_termination, but allows keyboard
14561 * callproc.c (Fcall_process): Add (:file "file") as an option for
14563 (Fcall_process_region): Ditto.
14565 2011-04-30 Eli Zaretskii <eliz@gnu.org>
14567 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
14568 rather than `XVECTOR (FOO)->size'.
14570 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
14571 inttypes.h, as a gnulib replacement is used if it not available in
14574 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14576 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
14577 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
14578 of MOST_POSITIVE_FIXNUM. (Bug#8528)
14580 * coding.c (coding_alloc_by_realloc): Error out if destination
14581 will grow beyond MOST_POSITIVE_FIXNUM.
14582 (decode_coding_emacs_mule): Abort if there isn't enough place in
14583 charbuf for the composition carryover bytes. Reserve an extra
14584 space for up to 2 characters produced in a loop.
14585 (decode_coding_iso_2022): Abort if there isn't enough place in
14586 charbuf for the composition carryover bytes.
14588 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14590 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
14591 aborting when %lld or %lll format is passed.
14592 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
14593 %llo or %llx format is passed. (Bug#8545)
14595 * window.c (window_scroll_line_based): Use a marker instead of
14596 simple variables to record original value of point. (Bug#7952)
14598 * doprnt.c (doprnt): Fix the case where a multibyte sequence
14599 produced by %s or %c overflows available buffer space. (Bug#8545)
14601 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
14603 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
14604 (SIZE_MAX): Move defn after all includes, as they might #define it.
14606 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

14610 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14612 * keyboard.c (Qdelayed_warnings_hook): Define.
14613 (command_loop_1): Run `delayed-warnings-hook'
14614 if Vdelayed_warnings_list is non-nil.
14615 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
14616 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
14618 2011-04-28 Eli Zaretskii <eliz@gnu.org>
14620 * doprnt.c (doprnt): Don't return value smaller than the buffer
14621 size if the message was truncated. (Bug#8545).
14623 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14625 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
14626 (Fx_window_property): #if-0 the whole functions, not just the bodies.
14628 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14630 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
14632 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
14634 * makefile.w32-in: Update dependencies.
14636 2011-04-27 Eli Zaretskii <eliz@gnu.org>
14638 Improve `doprnt' and its usage. (Bug#8545)
14639 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
14640 `format_end'. Remove support for %l as a conversion specifier.
14641 Don't use xrealloc. Improve diagnostics when the %l size modifier
14642 is used. Update the commentary.
14644 * eval.c (verror): Simplify calculation of size_t.
14646 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
14649 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
14651 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
14654 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14656 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
14657 This makes this file independent of the recent pseudovector change.
14659 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
14661 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
14663 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
14664 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
14665 Remove unused local.
14666 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
14668 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
14669 GCC 4.6.0 optimizes based on type-based alias analysis.
14670 For example, if b is of type struct buffer * and v of type struct
14671 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
14672 != &v->size, and therefore "v->size = 1; b->size = 2; return
14673 v->size;" must therefore return 1. This assumption is incorrect
14674 for Emacs, since it type-puns struct Lisp_Vector * with many other
14675 types. To fix this problem, this patch adds a new type struct
14676 vectorlike_header that documents the constraints on layout of vectors
14677 and pseudovectors, and helps optimizing compilers not get fooled
14678 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
14679 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
14680 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
14682 (XSETPVECTYPE): Rewrite in terms of new macro.
14683 (XSETPVECTYPESIZE): New macro, specifying both type and size.
14684 This is a bit clearer, and further avoids the possibility of
14685 undesirable aliasing.
14686 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
14687 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
14688 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
14689 since Lisp_Subr is a special case (no "next" field).
14690 (ASIZE): Now uses header.size rather than size.
14691 All previous uses of XVECTOR (foo)->size replaced to use this macro,
14692 to avoid the hassle of writing XVECTOR (foo)->header.size.
14693 (struct vectorlike_header): New type.
14694 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
14695 object, to help avoid aliasing.
14696 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
14697 (SUBRP): Likewise, since Lisp_Subr is a special case.
14698 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
14699 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
14700 (struct Lisp_Hash_Table): Combine first two members into a single
14701 struct vectorlike_header member. All uses of "size" and "next" members
14702 changed to be "header.size" and "header.next".
14703 * buffer.h (struct buffer): Likewise.
14704 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
14705 * frame.h (struct frame): Likewise.
14706 * process.h (struct Lisp_Process): Likewise.
14707 * termhooks.h (struct terminal): Likewise.
14708 * window.c (struct save_window_data, struct saved_window): Likewise.
14709 * window.h (struct window): Likewise.
14710 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
14711 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
14712 * buffer.c (init_buffer_once): Likewise.
14713 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
14715 * process.c (Fformat_network_address): Use local var for size,
14718 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
14720 Make the Lisp reader and string-to-float more consistent (Bug#8525)
14721 * data.c (atof): Remove decl; no longer used or needed.
14722 (digit_to_number): Move to lread.c.
14723 (Fstring_to_number): Use new string_to_number function, to be
14724 consistent with how the Lisp reader treats infinities and NaNs.
14725 Do not assume that floating-point numbers represent EMACS_INT
14726 without losing information; this is not true on most 64-bit hosts.
14727 Avoid double-rounding errors, by insisting on integers when
14728 parsing non-base-10 numbers, as the documentation specifies.
14729 * lisp.h (string_to_number): New decl, replacing ...
14730 (isfloat_string): Remove.
14731 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
14732 (read1): Do not accept +. and -. as integers; this
14733 appears to have been a coding error. Similarly, do not accept
14734 strings like +-1e0 as floating point numbers. Do not report
14735 overflow for integer overflows unless the base is not 10 which
14736 means we have no simple and reliable way to continue.
14737 Break out the floating-point parsing into a new
14738 function string_to_number, so that Fstring_to_number parses
14739 floating point numbers consistently with the Lisp reader.
14740 (digit_to_number): Move here from data.c. Make it static inline.
14741 (E_CHAR, EXP_INT): Remove, replacing with ...
14742 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
14743 (string_to_number): New function, replacing isfloat_string.
14744 This function checks for valid syntax and produces the resulting
14745 Lisp float number too. Rework it so that string-to-number
14746 no longer mishandles examples like "1.0e+". Use strtoumax,
14747 so that overflow for non-base-10 numbers is reported only when
14748 there's no portable and simple way to convert to floating point.
14750 * textprop.c (set_text_properties_1): Rewrite for clarity,
14751 and to avoid GCC warning about integer overflow.
14753 * intervals.h (struct interval): Use EMACS_INT for members
14754 where EMACS_UINT might cause problems. See
14755 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
14756 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
14757 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
14759 (offset_intervals): Tell GCC not to worry about length overflow
14760 when negating a negative length.
14762 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
14763 (overrun_check_free): Likewise.
14765 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
14766 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
14769 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14770 (gnutls_make_error): Rename local to avoid shadowing.
14771 (gnutls_emacs_global_deinit): ifdef out; not used.
14772 (Fgnutls_boot): Use const for pointer to readonly storage.
14773 Comment out unused local. Fix pointer signedness problems.
14775 * lread.c (openp): Don't stuff size_t into an 'int'.
14776 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
14777 about possible signed overflow.
14779 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14780 (GDK_KEY_g): Don't define if already defined.
14781 (xg_prepare_tooltip): Avoid pointer signedness problem.
14782 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
14784 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
14785 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
14787 * xfns.c (Fx_window_property): Simplify a bit,
14788 to make a bit faster and to avoid GCC 4.6.0 warning.
14789 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
14791 * fns.c (internal_equal): Don't assume size_t fits in int.
14793 * alloc.c (compact_small_strings): Tighten assertion a little.
14795 Replace pEd with more-general pI, and fix some printf arg casts.
14796 * lisp.h (pI): New macro, generalizing old pEd macro to other
14797 conversion specifiers. For example, use "...%"pI"d..." rather
14798 than "...%"pEd"...".
14799 (pEd): Remove. All uses replaced with similar uses of pI.
14800 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
14801 * alloc.c (check_pure_size): Don't overflow by converting size to int.
14802 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
14803 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
14804 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
14805 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
14806 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
14808 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
14809 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
14810 * print.c (safe_debug_print, print_object): Likewise.
14811 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
14813 Use pI instead of if-then-else-abort. Use %p to avoid casts,
14814 avoiding the 0 flag, which is not portable.
14815 * process.c (Fmake_network_process): Use pI to avoid cast.
14816 * region-cache.c (pp_cache): Likewise.
14817 * xdisp.c (decode_mode_spec): Likewise.
14818 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
14819 behavior on 64-bit hosts with printf arg.
14820 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
14821 (x_stop_queuing_selection_requests): Likewise.
14822 (x_get_window_property): Don't truncate byte count to an 'int'
14825 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
14826 here, since it parses constructs like leading '-' and spaces,
14827 which are not wanted; and it overflows with large numbers.
14828 Instead, simply match F[0-9]+, which is what is wanted anyway.
14830 * alloc.c: Remove unportable assumptions about struct layout.
14831 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
14832 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
14833 (allocate_vectorlike, make_pure_vector): Use the new macros,
14834 plus offsetof, to remove unportable assumptions about struct layout.
14835 These assumptions hold on all porting targets that I know of, but
14836 they are not guaranteed, they're easy to remove, and removing them
14837 makes further changes easier.
14839 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
14840 This doesn't fix a bug but makes the code clearer.
14841 (string_overrun_cookie): Now const. Use initializers that
14842 don't formally overflow signed char, to avoid warnings.
14843 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
14844 can cause Emacs to crash when string overrun checking is enabled.
14845 (allocate_buffer): Don't assume sizeof (struct buffer) is a
14846 multiple of sizeof (EMACS_INT); it need not be, if
14847 alignof(EMACS_INT) < sizeof (EMACS_INT).
14848 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
14850 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

14877 2011-04-25 Eli Zaretskii <eliz@gnu.org>
14879 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
14880 "cast to pointer from integer of different size".
14882 Improve doprnt and its use in verror. (Bug#8545)
14883 * doprnt.c (doprnt): Document the set of format control sequences
14884 supported by the function. Use SAFE_ALLOCA instead of always
14887 * eval.c (verror): Don't limit the buffer size at size_max-1, that
14888 is one byte too soon. Don't use xrealloc; instead xfree and
14891 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
14893 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
14896 * gnutls.c: Renamed global_initialized to
14897 gnutls_global_initialized. Added internals for the
14898 :verify-hostname-error, :verify-error, and :verify-flags
14899 parameters of `gnutls-boot' and documented those parameters in the
14900 docstring. Start callback support.
14901 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
14902 unless a fatal error occurred. Call gnutls_alert_send_appropriate

14978 Many local variables are now size_t instead of int or unsigned.
14979 Improve overflow protection. Support `l' modifier for integer
14980 conversions. Support %l conversion. Don't assume an EMACS_INT
14981 argument for integer conversions and for %c.
14983 * lisp.h (doprnt): Restore prototype.
14985 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
14986 $(SRC)/character.h.

15000 * callint.c (Fcall_interactively): When displaying error message
15001 about invalid control letter, pass the character's codepoint, not

15006 codepoint of an invalid character, to avoid displaying a bogus
15009 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15010 `error', not SYMBOL_NAME itself.

15015 * charset.c (check_iso_charset_parameter): Fix incorrect argument
15016 to `error' in error message about FINAL_CHAR argument. Make sure
15017 FINAL_CHAR is a character, and use %c when it is passed as
15018 argument to `error'.
15020 2011-04-23 Eli Zaretskii <eliz@gnu.org>
15022 * s/ms-w32.h (localtime): Redirect to sys_localtime.
15024 * w32.c: Include <time.h>.

15084 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
15085 by pacifying GCC about it. Maybe it's time to retire it?
15086 * xfaces.c (USG, __TIMEVAL__): Likewise.
15088 * dispextern.h (struct redisplay_interface): Rename param
15089 to avoid shadowing.
15090 * termhooks.h (struct terminal): Likewise.
15091 * xterm.c (xembed_send_message): Likewise.
15093 * insdel.c (make_gap_smaller): Define only if
15094 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
15096 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
15099 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
15100 so that we aren't warned about unused symbols.

15117 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
15119 * xmenu.c (menu_help_callback): Pointer type fixes.

15137 compatible char. Avoid the old compiler warnings about
15138 out-of-range initializers by using, for example, '\xab' rather
15141 * xgselect.c (xgselect_initialize): Check vs interface
15142 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

15169 2011-04-16 Eli Zaretskii <eliz@gnu.org>
15171 * gnutls.c (Fgnutls_boot): Don't pass Lisp_Object to `error'.

15191 (bcmp_translate, regcomp, regexec, print_double_string)
15192 (group_in_compile_stack, re_search, re_search_2, regex_compile)
15193 (re_compile_pattern, re_exec): Declare arguments and local
15194 variables `size_t' and `ssize_t' and return values `regoff_t', as
15196 (POP_FAILURE_REG_OR_COUNT) <pfreg>: Declare `long'.
15197 (CHECK_INFINITE_LOOP) <failure>: Declare `ssize_t'.
15198 <compile_stack_type>: `size' and `avail' are now `size_t'.

15201 (re_search, re_search_2, re_match, re_match_2): Arguments that
15202 specify buffer/string position and length are now ssize_t and
15203 size_t. Return type is regoff_t.
15205 2011-04-16 Ben Key <bkey76@gmail.com>
15207 * nsfont.m: Fixed bugs in ns_get_family and
15208 ns_descriptor_to_entity that were caused by using free to
15209 deallocate memory blocks that were allocated by xmalloc (via
15210 xstrdup). This caused Emacs to crash when compiled with
15211 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
15212 --enable-checking=xmallocoverrun). xfree is now used to

15630 (Funintern, Fget_internal_run_time): New decls, since these functions
15631 were already external.
15633 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
15634 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
15635 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:

15638 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
15639 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
15640 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
15641 Mark functions with DEFUE instead of DEFUN,
15642 if they are used in other modules.
15643 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
15644 decls for now-static functions.
15645 * buffer.h (Fdelete_overlay): Remove decl.
15646 * callproc.c (Fgetenv_internal): Mark as internal.
15647 * composite.c (Fremove_list_of_text_properties): Remove decl.

15653 (Funintern): Remove extern decl; now in .h file where it belongs.
15654 * fileio.c (Fmake_symbolic_link): New forward static decl.
15655 * image.c (Finit_image_library): New forward static decl.
15656 * insdel.c (Fcombine_after_change_execute): Make forward decl static.

15681 2011-04-13 Eli Zaretskii <eliz@gnu.org>
15683 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
15684 when at ZV. (Bug#8487)
15686 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
15688 * charset.c (Fclear_charset_maps): Use xfree instead of free.
15690 * keyboard.c (parse_tool_bar_item): Likewise.
15691 * sound.c (sound_cleanup, alsa_close): Likewise.
15692 * termcap.c (tgetent): Likewise.
15693 * xfns.c (x_default_font_parameter): Likewise.
15694 * xsettings.c (read_and_apply_settings): Likewise.
15696 * alloc.c (overrun_check_malloc, overrun_check_realloc)
15697 (overrun_check_free): Protoize.
15699 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
15701 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
15702 since callers should never pass a negative size.
15703 Change the signature to match that of plain 'read' and 'write'; see
15704 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
15705 * lisp.h: Update prototypes of emacs_write and emacs_read.
15707 2011-04-11 Eli Zaretskii <eliz@gnu.org>
15709 * xdisp.c (redisplay_window): Don't try to determine the character
15710 position of the scroll margin if the window start point w->startp
15711 is outside the buffer's accessible region. (Bug#8468)
15713 2011-04-10 Eli Zaretskii <eliz@gnu.org>
15715 Fix write-region and its subroutines for buffers > 2GB.
15716 * fileio.c (a_write, e_write): Modify declaration of arguments and
15717 local variables to support buffers larger than 2GB.
15718 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
15720 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
15721 argument, local variables, and return value.
15723 * lisp.h: Update prototypes of emacs_write and emacs_read.
15725 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
15727 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
15729 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
15731 Fix more problems found by GCC 4.6.0's static checks.
15733 * xdisp.c (vmessage): Use a better test for character truncation.
15735 * charset.c (load_charset_map): <, not <=, for optimization,
15736 and to avoid potential problems with integer overflow.
15737 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
15738 * casetab.c (set_identity, shuffle): Likewise.
15739 * editfns.c (Fformat): Likewise.
15740 * syntax.c (skip_chars): Likewise.
15742 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
15743 This also lets GCC 4.6.0 generate slightly better loop code.
15745 * callint.c (Fcall_interactively): <, not <=, for optimization.
15746 (Fcall_interactively): Count the number of arguments produced,
15747 not the number of arguments given. This is simpler and lets GCC
15748 4.6.0 generate slightly better code.
15750 * ftfont.c: Distingish more carefully between FcChar8 and char.
15751 The previous code passed unsigned char * to a functions like
15752 strlen and xstrcasecmp that expect char *, which does not
15753 conform to the C standard.
15754 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
15755 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
15756 char * when the C standard requires it.
15758 * keyboard.c (read_char): Remove unused var.
15760 * eval.c: Port to Windows vsnprintf (Bug#8435).
15761 Include <limits.h>.
15762 (SIZE_MAX): Define if the headers do not.
15763 (verror): Do not give up if vsnprintf returns a negative count.
15764 Instead, grow the buffer. This ports to Windows vsnprintf, which
15765 does not conform to C99. Problem reported by Eli Zaretskii.
15766 Also, simplify the allocation scheme, by avoiding the need for
15767 calling realloc, and removing the ALLOCATED variable.
15769 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
15771 Remove invocations of doprnt, as Emacs now uses vsnprintf.
15772 But keep the doprint source code for now, as we might revamp it
15773 and use it again (Bug#8435).
15774 * lisp.h (doprnt): Remove.
15775 * Makefile.in (base_obj): Remove doprnt.o.
15776 * deps.mk (doprnt.o): Remove.
15778 error: Print 32- and 64-bit integers portably (Bug#8435).
15779 Without this change, on typical 64-bit hosts error ("...%d...", N)
15780 was used to print both 32- and 64-bit integers N, which relied on
15781 undefined behavior.
15782 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
15783 * lisp.h (error, verror): Mark as printf-like functions.
15784 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
15785 Report overflow in size calculations when allocating printf buffer.
15786 Do not truncate output string at its first null byte.
15787 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
15788 Truncate the output at a character boundary, since vsnprintf does not
15790 * charset.c (check_iso_charset_parameter): Convert internal
15791 character to string before calling 'error', since %c now has the
15793 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
15794 overflow when computing char to be passed to 'error'. Do not
15795 pass Lisp_Object to 'error'; pass the integer instead.
15796 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
15797 formatted with plain %d.
15799 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
15801 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
15803 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
15805 * xterm.c (x_catch_errors): Remove duplicate declaration.
15807 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
15809 * xdisp.c, lisp.h (message_nolog): Remove; unused.
15811 2011-04-10 Jim Meyering <meyering@redhat.com>
15813 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
15814 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
15815 return ssize_t not "int", and use size_t as the buffer length.
15816 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
15817 * gnutls.h: Update declarations.
15818 * process.c (read_process_output): Use ssize_t, to match.
15819 (send_process): Likewise.
15821 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15823 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
15825 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15827 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
15828 Use unsigned char, to match FcChar8 type definition.
15830 * xterm.c (handle_one_xevent):
15831 * xmenu.c (create_and_show_popup_menu):
15832 * xselect.c (x_decline_selection_request)
15833 (x_reply_selection_request): Avoid type-punned deref of X events.
15835 2011-04-09 Eli Zaretskii <eliz@gnu.org>
15837 Fix some uses of `int' instead of EMACS_INT.
15838 * search.c (string_match_1, fast_string_match)
15839 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
15840 (scan_buffer, find_next_newline_no_quit)
15841 (find_before_next_newline, search_command, Freplace_match)
15842 (Fmatch_data): Make some `int' variables be EMACS_INT.
15844 * xdisp.c (display_count_lines): 3rd argument and return value now
15845 EMACS_INT. All callers changed.
15846 (pint2hrstr): Last argument is now EMACS_INT.
15848 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
15849 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
15850 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
15851 (decode_coding_utf_16, decode_coding_emacs_mule)
15852 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
15853 (decode_coding_ccl, decode_coding_charset)
15854 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
15855 (decode_coding_iso_2022, decode_coding_emacs_mule)
15856 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
15857 <char_offset, last_offset>: Declare EMACS_INT.

15859 (encode_coding_emacs_mule, encode_invocation_designation)
15860 (encode_designation_at_bol, encode_coding_iso_2022)
15861 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
15862 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
15864 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
15865 (encode_invocation_designation): Last argument P_NCHARS is now
15867 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
15868 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
15870 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
15873 * ccl.c (Fccl_execute_on_string): Declare some variables
15876 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
15878 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
15880 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
15882 * process.c (Fformat_network_address): Doc fix.
15884 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
15886 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
15888 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
15890 * keyboard.c (read_char): Call Lisp function help-form-show,
15891 instead of using internal_with_output_to_temp_buffer.
15892 (Qhelp_form_show): New var.
15893 (syms_of_keyboard): Use DEFSYM macro.
15895 * print.c (internal_with_output_to_temp_buffer): Function deleted.
15897 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
15899 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
15901 * process.c (Flist_processes): Remove to Lisp.
15902 (list_processes_1): Delete.
15904 2011-04-06 Eli Zaretskii <eliz@gnu.org>
15906 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
15908 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
15910 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
15912 Fix more problems found by GCC 4.6.0's static checks.
15914 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
15916 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
15918 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
15920 * xdisp.c (vmessage): Mark as a printf-like function.
15922 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
15924 * sound.c (sound_warning): Don't crash if arg contains a printf format.
15926 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
15927 printf-like functions.

15929 to system-supplied API.
15931 * eval.c (Fsignal): Remove excess argument to 'fatal'.
15933 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
15934 This avoids several warnings with gcc -Wstrict-overflow.
15935 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
15936 directly, rather than having caller test rule sign. This avoids
15937 some unnecessary tests.
15938 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
15939 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
15940 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
15942 * xfont.c (xfont_text_extents): Remove var that was set but not used.
15943 (xfont_open): Avoid unnecessary tests.
15945 * composite.c (composition_gstring_put_cache): Use unsigned integer.
15947 * composite.h, composite.c (composition_gstring_put_cache):
15948 Use EMACS_INT, not int, for length.

15951 breaking out part of COMPOSITION_DECODE_RULE.
15952 (COMPOSITION_DECODE_RULE): Use it.

15954 by using the new macro.
15956 * textprop.c (set_text_properties_1): Change while to do-while,
15957 since the condition is always true at first.
15959 * intervals.c (graft_intervals_into_buffer): Mark var as used.
15960 (interval_deletion_adjustment): Return unsigned value.
15963 * process.c (list_processes_1, create_pty, read_process_output):

15973 (update_syntax_table): Use unsigned instead of int.
15975 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
15976 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
15977 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
15979 * print.c (print_error_message): Avoid int overflow.
15981 * font.c (font_list_entities): Redo for clarity,
15982 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
15984 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
15985 (font_score): Avoid potential overflow in diff calculation.
15987 * fns.c (substring_both): Remove var that is set but not used.
15988 (sxhash): Redo loop for clarity and to avoid wraparound warning.
15990 * eval.c (funcall_lambda): Rename local to avoid shadowing.
15992 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
15993 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
15994 can always succeed if overflow has undefined behavior.
15996 * search.c (boyer_moore, wordify): Remove vars set but not used.
15997 (wordify): Omit three unnecessary tests.
15999 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
16000 All callers changed. This avoids the need for an unused var.
16002 * casefiddle.c (casify_region): Remove var that is set but not used.
16004 * dired.c (file_name_completion): Remove var that is set but not used.
16006 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
16008 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16009 (Finsert_file_contents): Remove unnecessary code checking fd.
16011 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
16012 Check for integer overflow on size calculations.
16014 * buffer.c (Fprevious_overlay_change): Remove var that is set
16017 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16018 Remove vars that are set but not used.
16019 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16020 (timer_check_2): Mark vars as initialized.
16022 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16024 * image.c (lookup_image): Remove var that is set but not used.
16025 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16027 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16028 that are set but not used.
16030 * xfns.c (make_invisible_cursor): Don't return garbage
16031 if XCreateBitmapFromData fails (Bug#8410).
16033 * xselect.c (x_get_local_selection, x_handle_property_notify):
16034 Remove vars that are set but not used.
16036 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
16037 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
16039 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
16040 Remove var that is set but not used.

16042 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16043 Check for overflow.
16045 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16046 (map_tty_color) [!defined MSDOS]: Likewise.
16048 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16050 * coding.c: Remove vars that are set but not used.
16051 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
16052 All callers changed.
16053 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
16054 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
16055 (decode_coding_charset): Remove vars that are set but not used.
16057 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
16058 that is set but not used.
16060 * print.c (print_object): Remove var that is set but not used.
16062 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16063 The gnulib version avoids calling malloc in the usual case,
16064 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16065 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16066 * filelock.c (current_lock_owner): Likewise.
16067 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16068 * sysdep.c: Include allocator.h, careadlinkat.h.
16069 (emacs_no_realloc_allocator): New static constant.
16070 (emacs_readlink): New function.
16071 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16072 ../lib/careadlinkat.h.

16076 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
16077 first non-nil return value).

16093 (get_per_char_metric): Remove parameter `f', unused since
16094 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
16096 2011-04-02 Jim Meyering <meyering@redhat.com>
16098 do not dereference NULL upon failed strdup
16099 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16100 (ns_get_family): Likewise.
16102 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16104 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16106 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16108 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16111 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16113 Add lexical binding.
16115 * window.c (Ftemp_output_buffer_show): New fun.
16116 (Fsave_window_excursion):
16117 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.

16122 Bind Qinternal_interpreter_environment.
16123 (Feval_buffer): Bind Qlexical_binding.
16124 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16126 (syms_of_lread): Declare `lexical-binding'.
16128 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16130 * keyboard.c (eval_dyn): New fun.
16131 (menu_item_eval_property): Use it.
16133 * image.c (parse_image_spec): Use Ffunctionp.
16135 * fns.c (concat, mapcar1): Accept byte-code-functions.
16137 * eval.c (Fsetq): Handle lexical vars.
16138 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16139 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16140 (FletX, Flet): Obey lexical binding.
16141 (Fcommandp): Handle closures.
16142 (Feval): New `lexical' arg.
16143 (eval_sub): New function extracted from Feval. Use it almost
16144 everywhere where Feval was used. Look up vars in lexical env.
16146 (Ffunctionp): Move from subr.el.
16147 (Ffuncall): Handle closures.
16148 (apply_lambda): Remove `eval_flags'.
16149 (funcall_lambda): Handle closures and new byte-code-functions.
16150 (Fspecial_variable_p): New function.
16151 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16152 but without exporting it to Lisp.
16154 * doc.c (Fdocumentation, store_function_docstring):
16155 * data.c (Finteractive_form): Handle closures.
16157 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16160 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16162 (exec_byte_code): New function extracted from Fbyte_code to handle new
16163 calling convention for byte-code-functions. Add new byte-codes.
16165 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
16167 * alloc.c (Fmake_symbol): Init new `declared_special' field.
16169 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16171 * xdisp.c (redisplay_internal): Fix prototype.
16173 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16175 * xdisp.c (SCROLL_LIMIT): New macro.
16176 (try_scrolling): Use it when setting scroll_limit.
16177 Limit scrolling to 100 screen lines.
16178 (redisplay_window): Even when falling back on "recentering",
16179 position point in the window according to scroll-conservatively,
16180 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16182 (try_scrolling): When point is above the window, allow searching
16183 as far as scroll_max, or one screenful, to compute vertical
16184 distance from PT to the scroll margin position. This prevents
16185 try_scrolling from unnecessarily failing when
16186 scroll-conservatively is set to a value slightly larger than the
16187 window height. Clean up the case of PT below the margin at bottom
16188 of window: scroll_max can no longer be INT_MAX. When aggressive
16189 scrolling is in use, don't let point enter the opposite scroll
16190 margin as result of the scroll.
16191 (syms_of_xdisp) <scroll-conservatively>: Document the
16192 threshold of 100 lines for never-recentering scrolling.
16194 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16196 * dispextern.h (move_it_by_lines):
16197 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
16198 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
16199 (message_log_check_duplicate): Remove parameters `prev_bol' and
16200 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16201 (redisplay_internal): Remove parameter `preserve_echo_area',
16202 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16204 * indent.c (Fvertical_motion):
16205 * window.c (window_scroll_pixel_based, Frecenter):
16206 Don't pass `need_y_p' to `move_it_by_lines'.
16208 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16210 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16211 steal a few bits to be more compact.
16212 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16213 Remove unneeded casts.
16215 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16217 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16219 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16220 binding" message (bug#7967).
16222 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16224 Fix more problems found by GCC 4.6.0's static checks.
16226 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16227 Remove unused local var.
16229 * editfns.c (Fmessage_box): Remove unused local var.
16231 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16232 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16233 Omit unused local vars.
16234 * window.c (shrink_windows): Omit unused local var.
16235 * menu.c (digest_single_submenu): Omit unused local var.
16236 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16237 Omit unused local var.
16239 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16240 Don't assume string length fits in int.
16241 (keyremap_step, read_key_sequence): Use size_t for sizes.
16242 (read_key_sequence): Don't check last_real_key_start redundantly.
16244 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
16245 instead of alloca (Bug#8344).
16247 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16248 (Fbacktrace_frame): Don't assume nframes fits in int.
16250 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
16252 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
16255 * term.c (produce_glyphless_glyph): Remove unnecessary test.
16257 * cm.c (calccost): Turn while-do into do-while, for clarity.
16259 * keyboard.c (syms_of_keyboard): Use the same style as later
16260 in this function when indexing through an array. This also
16261 works around GCC bug 48267.
16263 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16265 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16267 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16268 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16270 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16271 This avoids undefined behavior on integer overflow, and is a bit
16272 more convenient anyway since it is compared to a size_t variable.
16274 Variadic C functions now count arguments with size_t, not int.
16275 This avoids an unnecessary limitation on 64-bit machines, which
16276 caused (substring ...) to crash on large vectors (Bug#8344).

16286 * fns.c (concat): Likewise.
16287 * frame.c (x_set_frame_parameters): Likewise.
16288 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16289 0 if not found, not -1. All callers changed.
16291 * alloc.c (garbage_collect): Don't assume stack size fits in int.
16292 (stack_copy_size): Now size_t, not int.
16293 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
16295 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
16297 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',

16302 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
16303 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

16314 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
16315 don't set the hook to nil, but remove the offending function instead.
16316 (Qcommand_hook_internal): Remove, unused.
16317 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
16318 Vcommand_hook_internal.
16320 * eval.c (enum run_hooks_condition): Remove.
16321 (funcall_nil, funcall_not): New functions.
16322 (run_hook_with_args): Call each function through a `funcall' argument.

16501 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
16502 unconditionally since it does the check itself.
16504 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
16506 Fix more problems found by GCC 4.5.2's static checks.
16508 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16509 the first time through the loop, since we know p0 < p1 then.
16510 This also avoids a gcc -Wstrict-overflow warning.
16512 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16513 leading to a memory leak, possible in functions like
16514 load_charset_map_from_file that can allocate an unbounded number
16515 of objects (Bug#8318).
16517 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16518 that could (at least in theory) be that large.
16520 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16521 This is less likely to overflow, and avoids undefined behavior if
16522 overflow does occur. All callers changed. Use strtoul to scan
16523 for the unsigned long integer.
16524 (pint2hrstr): Simplify and tune code slightly.
16525 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
16527 * scroll.c (do_scrolling): Work around GCC bug 48228.
16528 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

16531 This also avoids a warning with gcc -Wstrict-overflow.
16532 (validate_x_resource_name): Simplify count usage.
16533 This also avoids a warning with gcc -Wstrict-overflow.
16535 * fileio.c (Fcopy_file): Report error if fchown or fchmod
16538 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
16540 * process.c (Fmake_network_process): Use socklen_t, not int,
16541 where POSIX says socklen_t is required in portable programs.
16542 This fixes a porting bug on hosts like 64-bit HP-UX, where
16543 socklen_t is wider than int (Bug#8277).
16544 (Fmake_network_process, server_accept_connection):
16545 (wait_reading_process_output, read_process_output):
16548 * process.c: Rename or move locals to avoid shadowing.

16558 Make tparam.h and terminfo.c consistent.
16559 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
16560 Include tparam.h instead, since it declares them.
16561 * cm.h (PC): Remove extern decl; tparam.h now does this.
16562 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
16563 * terminfo.c: Include tparam.h, to check interfaces.
16564 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
16565 (tparam): Adjust signature to match interface in tparam.h;
16566 this removes some undefined behavior. Check that outstring and len
16567 are zero, which they always are with Emacs.
16568 * tparam.h (PC, BC, UP): New extern decls.
16570 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
16571 (xftfont_open): Rename locals to avoid shadowing.

16588 (find_automatic_composition, composition_adjust_point): Likewise.
16589 (composition_update_it): Mark var as initialized.
16590 (find_automatic_composition): Mark vars as initialized,
16591 with a FIXME (Bug#8290).

16595 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
16596 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
16597 (BUF_DEC_POS): Be more systematic about renaming local temporaries
16598 to avoid shadowing.
16600 * textprop.c (property_change_between_p): Remove; unused.
16602 * intervals.c (interval_start_pos): Now static.
16604 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

16609 * sound.c (wav_play, au_play, Fplay_sound_internal):
16610 Fix pointer signedness.
16611 (alsa_choose_format): Remove unused local var.
16612 (wav_play): Initialize a variable to 0, to prevent undefined
16613 behavior (Bug#8278).
16615 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
16617 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
16619 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
16620 clobbering (Bug#8298).
16621 * sysdep.c (sys_subshell): Likewise.
16622 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
16624 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
16625 This should get cleaned up, so that child_setup has the
16626 same signature on all platforms.
16628 * callproc.c (call_process_cleanup): Now static.
16629 (relocate_fd): Rename locals to avoid shadowing.
16631 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
16633 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
16634 not to be necessary, and produces flickering.
16636 2011-03-20 Glenn Morris <rgm@gnu.org>
16638 * config.in: Remove file.
16640 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
16642 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
16643 are now in src/globals.h.
16644 (syms_of_minibuf): Remove spurious & from previous change.
16646 2011-03-20 Leo Liu <sdl.web@gmail.com>

16654 * xfaces.c (Fx_load_color_file):
16655 Read color file from absolute filename (bug#8250).
16657 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16659 * makefile.w32-in: Update dependencies.
16661 2011-03-17 Eli Zaretskii <eliz@gnu.org>
16663 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

16670 (sigchld_handler): Now static.
16672 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
16673 That way, the code declares only the vars that it needs.

16683 (CONSTANTLIM): Remove; unused.
16684 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
16685 Define only if needed.
16687 * unexelf.c (unexec): Name an expression,
16688 to avoid gcc -Wbad-function-cast warning.
16689 Use a different way to cause a compilation error if anyone uses
16690 n rather than nn, a way that does not involve shadowing.
16691 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
16693 * deps.mk (unexalpha.o): Remove; unused.
16695 New file unexec.h, the (simple) interface for unexec (Bug#8267).
16696 * unexec.h: New file.
16697 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
16698 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
16699 Depend on unexec.h.
16700 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
16701 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
16702 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
16703 Change as necessary to match prototype in unexec.h.

16750 * callint.c (quotify_arg, quotify_args): Now static.
16751 (Fcall_interactively): Rename locals to avoid shadowing.
16752 Use const pointer when appropriate.

16758 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
16759 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
16760 some of which prompt warnings from gcc -Wbad-function-cast.
16761 (Fformat_time_string, Fencode_time, Finsert_char):
16762 (Ftranslate_region_internal, Fformat):
16763 Rename or remove local vars to avoid shadowing.
16764 (Ftranslate_region_internal): Mark var as initialized.
16766 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
16769 * lisp.h (eassert): Check that the argument compiles, even if
16770 ENABLE_CHECKING is not defined.
16772 * data.c (Findirect_variable): Name an expression, to avoid
16773 gcc -Wbad-function-cast warning.
16774 (default_value, arithcompare, arith_driver, arith_error): Now static.

16785 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
16786 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
16788 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
16789 (GC_STRING_CHARS): Remove; not used.
16790 (Fmemory_limit): Cast sbrk's returned value to char *.
16792 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
16793 avoids undefined behavior in theory.
16795 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
16797 Use functions, not macros, for up- and down-casing (Bug#8254).
16798 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16799 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
16800 to use the following functions instead of these macros.
16801 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
16802 EMACS_INT, since callers assume the returned value fits in int.
16803 (upcase1): Likewise, for UPCASE_TABLE.
16804 (uppercasep, lowercasep, upcase): New static inline functions.
16805 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
16806 the race-condition problem in the old DOWNCASE.

16814 which gcc can warn about.
16815 (regex_compile, re_match_2_internal): Mark locals as initialized.
16816 (RETALLOC_IF): Define only if needed.
16817 (WORDCHAR_P): Likewise. This one is never needed, but is used
16818 only in a comment talking about a compiler bug, so put inside
16819 the #if 0 of that comment.
16820 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
16821 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
16824 * search.c (boyer_moore): Rename locals to avoid shadowing.
16825 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

16847 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
16848 New macros, so that the caller can use some names other than
16849 gcpro1, gcpro2, etc.
16850 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
16852 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
16853 argument, for consistency with GCPRO2_VAR, etc: it is now the
16854 prefix of the variable, not the variable itself. All uses
16856 * dired.c (directory_files_internal, file_name_completion):
16857 Rename locals to avoid shadowing.
16859 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
16860 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
16861 dired.c's scmp function, had undefined behavior.
16862 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16863 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
16864 * buffer.h: ... to here, because these macros use current_buffer,
16865 and the new implementation with inline functions needs to have
16866 current_buffer in scope now, rather than later when the macros
16868 (downcase, upcase1): New static inline functions.
16869 (DOWNCASE, UPCASE1): Reimplement using these functions.
16870 This avoids undefined behavior in expressions like
16871 DOWNCASE (x) == DOWNCASE (y), which previously suffered
16872 from race conditions in accessing the global variables
16873 case_temp1 and case_temp2.
16874 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
16875 * lisp.h (case_temp1, case_temp2): Remove their decls.
16876 * character.h (ASCII_CHAR_P): Move from here ...
16877 * lisp.h: ... to here, so that the inline functions mentioned
16878 above can use them.
16880 * dired.c (directory_files_internal_unwind): Now static.
16882 * fileio.c (file_name_as_directory, directory_file_name):
16883 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
16885 (file_name_as_directory): Use const pointers when appropriate.
16886 (Fexpand_file_name): Likewise. In particular, newdir might
16887 point at constant storage, so make it a const pointer.
16888 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
16889 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
16891 (Fset_file_times, Finsert_file_contents, auto_save_error):
16892 Rename locals to avoid shadowing.
16894 * minibuf.c (choose_minibuf_frame_1): Now static.

16896 to avoid shadowing.
16898 * marker.c (bytepos_to_charpos): Remove; unused.
16900 * lisp.h (verify_bytepos, count_markers): New decls,
16901 so that gcc does not warn that these functions aren't declared.
16903 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
16904 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
16905 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
16906 (copy_text): Remove unused local var.
16908 * filelock.c (within_one_second): Now static.
16909 (lock_file_1): Rename local to avoid shadowing.
16911 * buffer.c (fix_overlays_before): Mark locals as initialized.
16912 (fix_start_end_in_overlays): Likewise. This function should be
16913 simplified by using pointers-to-pointers, but that's a different
16915 (switch_to_buffer_1): Now static.
16916 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
16917 (report_overlay_modification): Rename locals to avoid shadowing.
16919 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
16920 Fix pointer signedness issue.
16921 (sys_subshell): Mark local as volatile if checking for lint,
16922 to suppress a gcc -Wclobbered warning that does not seem to be right.
16923 (MAXPATHLEN): Define only if needed.
16925 * process.c (serial_open, serial_configure): Move decls from here ...
16926 * systty.h: ... to here, so that they can be checked.
16928 * fns.c (get_random, seed_random): Move extern decls from here ...
16929 * lisp.h: ... to here, so that they can be checked.
16931 * sysdep.c (reset_io): Now static.
16932 (wait_for_termination_signal): Remove; unused.
16934 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
16935 (copy_keymap_item, append_key, push_text_char_description):
16937 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
16938 (DENSE_TABLE_SIZE): Remove; unused.
16939 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
16940 (describe_map_tree):
16941 Rename locals to avoid shadowing.
16943 * keyboard.c: Declare functions static if they are not used elsewhere.

16949 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
16950 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
16951 (read_key_sequence, read_char): Mark locals as initialized.
16952 (Fexit_recursive_edit, Fabort_recursive_edit): Mark with NO_RETURN.

16956 * alloc.c (mark_kboards): ... from here.
16958 * lisp.h (force_auto_save_soon): New decl.
16960 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
