3 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4 the new overlay string. (Bug#10159)
6 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
8 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
9 or that fprintf is async-signal-safe. POSIX doesn't require
12 2012-09-22 Chong Yidong <cyd@gnu.org>
14 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
17 2012-09-22 Kenichi Handa <handa@gnu.org>
19 * composite.c (composition_reseat_it): Handle the case that a
20 grapheme cluster is not covered by a single font (Bug#12352).
22 2012-09-21 Chong Yidong <cyd@gnu.org>
24 * image.c (define_image_type): Avoid adding duplicate types to
25 image_types (Bug#12463). Suggested by Jörg Walter.
27 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
29 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
30 (print_load_command_name): Add case LC_DATA_IN_CODE.
31 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
33 2012-09-21 Glenn Morris <rgm@gnu.org>
35 * eval.c (Frun_hook_with_args_until_success)
36 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
38 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
40 * fileio.c (Ffile_selinux_context): Only call freecon when
41 lgetfilecon succeeded.
42 (Fset_file_selinux_context): Likewise. (Bug#12444)
44 2012-09-21 Eli Zaretskii <eliz@gnu.org>
46 * xdisp.c (try_window_reusing_current_matrix): Under bidi
47 reordering, locate the cursor by calling set_cursor_from_row; if
48 that fails, clear the desired glyph matrix before returning a
49 failure indication to the caller. Fixes leaving garbled display
50 when fast scrolling with a down-key. (Bug#12403)
51 (compute_stop_pos_backwards): Fix a typo that caused crashes while
52 scrolling through multibyte text.
54 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
56 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
57 calling mark_vectorlike since that's the one that marks the window.
58 (mark_discard_killed_buffers): Mark the final cdr.
59 * window.h (struct window): Move prev/next_buffers to the
61 * window.c (make_window): Initialize prev/next_buffers manually.
63 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
65 Omit unused arg EXPECTED from socket hooks.
66 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
67 * nsterm.m (ns_term_init):
68 * termhooks.h (struct terminal.read_socket_hook):
69 * w32inevt.c (w32_console_read_socket):
70 * w32term.c (w32_read_socket):
71 * xterm.c (XTread_socket):
72 Omit unused arg EXPECTED. All callers changed.
73 (store_user_signal_events): Return void, not int, since callers no
74 longer care about the return value. All uses changed.
76 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
78 * w32gui.h (XParseGeometry): Do not declare.
80 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
82 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
83 Ignore 'expected'. See Eli Zaretskii in
84 <http://bugs.gnu.org/12471#8> (last line).
86 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
87 (XParseGeometry): Now static. Substitute extremal values for
88 values that are out of range.
90 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
92 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
94 * nsfns.m (XParseGeometry): Remove.
95 (Fx_create_frame): Call x_set_offset to correctly interpret
98 * frame.c (read_integer, XParseGeometry): Moved from w32xfns.c.
99 (Fx_parse_geometry): If there is a space in string, call
100 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
102 2012-09-17 Eli Zaretskii <eliz@gnu.org>
104 * search.c (scan_buffer): Use character positions in calls to
105 region_cache_forward and region_cache_backward, not byte
106 positions. (Bug#12196)
108 * w32term.c (w32_read_socket): Set pending_signals to 1, like
109 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
111 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
112 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
113 emacs_blocked_malloc, now deleted.
115 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
117 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
118 The workaround was for improving performance on Solaris 2.4, but
119 is getting in the way now. Emacs will still work if someone is
120 still running Solaris 2.4 in a museum somewhere; Sun dropped
121 support for Solaris 2.4 in 2003.
122 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
123 * process.c (create_process) [HAVE_WORKING_VFORK]:
124 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
125 since Emacs no longer uses vfork on that platform.
127 2012-09-17 Glenn Morris <rgm@gnu.org>
129 * emacs.c: Use COPYRIGHT.
131 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
133 Remove configure's --without-sync-input option (Bug#12450).
134 When auditing signal-handling in preparation for cleaning it up,
135 I found that SYNC_INPUT has race conditions and would be a real
136 pain to fix. Since it's an undocumented and deprecated
137 configure-time option, now seems like a good time to remove it.
138 Also see <http://bugs.gnu.org/11080#16>.
139 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
140 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
141 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
143 (check_depth) [XMALLOC_OVERRUN_CHECK]:
144 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
145 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
146 (dont_register_blocks, bytes_used_when_reconsidered)
147 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
148 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
149 [!SYSTEM_MALLOC && !SYNC_INPUT]:
150 Remove. All uses removed.
151 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
152 implementation, one that depends on whether the new macro
153 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
155 * atimer.c (run_timers, handle_alarm_signal):
156 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
157 (handle_async_input, process_pending_signals)
158 (handle_input_available_signal, init_keyboard):
159 * nsterm.m (ns_read_socket):
160 * process.c (wait_reading_process_output):
161 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
162 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
164 * xterm.c (XTread_socket):
166 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
167 * eval.c (handling_signal): Remove. All uses removed.
168 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
169 All uses replaced with the SYNC_INPUT version.
170 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
172 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
175 * font.c (Ffont_shape_gstring): Remove unused local.
177 2012-09-16 Glenn Morris <rgm@gnu.org>
179 * Makefile.in (clean): No longer run nextstep's clean.
181 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
183 (ns-app): Move here from ns.mk, and simplify.
184 (clean): Simplify nextstep entry.
185 * ns.mk: Remove file.
187 2012-09-17 Kenichi Handa <handa@gnu.org>
189 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
190 not covert the last few charactes.
192 2012-09-16 Kenichi Handa <handa@gnu.org>
194 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
195 here, but just check the validity of glyphs in the glyph-string.
197 2012-09-16 Martin Rudalics <rudalics@gmx.at>
199 * window.c (Fwindow_parameter, Fset_window_parameter): Accept
200 any window as argument (Bug#12452).
202 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
204 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
205 to ns_term_init to avoid memory leak.
207 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
208 explicit retain/release.
209 (ns_term_init): Only allow one display. Initialize outerpool and
212 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
214 Port _setjmp fix to POSIXish hosts as well as Microsoft.
215 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
216 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
217 the Microsoft problem in a different way, by altering ../nt/config.nt.
219 2012-09-15 Eli Zaretskii <eliz@gnu.org>
234 * w16select.c: Remove inclusion of setjmp.h, as it is now included
235 by lisp.h. This completes removal of setjmp.h inclusion
236 erroneously announced in the previous commit. (Bug#12446)
238 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
241 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
242 not defined as a macro. The latter happens on MS-Windows.
245 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
247 Port better to POSIX hosts lacking _setjmp (Bug#12446).
248 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
249 Some instances of '#include <setjmp.h>' removed, if the
250 only reason for the instance was because "lisp.h" was included.
251 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
252 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
253 and _longjmp with the new symbols. Emacs already uses _setjmp if
254 available, so this change affects only POSIXish hosts that have
255 sigsetjmp but not _setjmp, such as some versions of Solaris and
256 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
257 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
258 (png_load_body) [HAVE_PNG]:
259 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
260 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
261 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
262 since PNG requires jmp_buf. This is the only exception to the
263 general rule that we now use sys_setjmp and sys_longjmp.
264 This exception is OK since this code does not change the signal
265 mask or longjmp out of a signal handler.
267 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
269 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
270 Include "syssignal.h", for 'main_thread'.
272 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
274 Avoid out-of-range marker position (Bug#12426).
275 * insdel.c (replace_range, replace_range_2): Adjust
276 markers before overlays, as suggested by comments.
277 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
278 Remove redundant check before calling offset_intervals.
280 2012-09-14 Martin Rudalics <rudalics@gmx.at>
282 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
283 current buffer (Bug#12387).
285 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
287 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
289 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
291 Use a more backwards-compatible timer format (Bug#12430).
292 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
293 vector element, not from the 4th, since PSECS is now at the end.
294 (Fcurrent_idle_time): Doc fix.
296 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
298 Function to mark objects and remove killed buffers at once.
299 * alloc.c (discard_killed_buffers): Rename to ...
300 (mark_discard_killed buffers) ... new name. Add marking
301 of remaining objects. Fix comment. Adjust users.
302 (mark_object): Do not touch frame buffer lists here.
303 * frame.c (delete_frame): Reset frame buffer lists here.
305 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
307 Better workaround for GNOME bug when --enable-gcc-warnings.
308 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
309 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
310 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
312 Simplify SIGIO usage (Bug#12408).
313 The code that dealt with SIGIO was crufty and confusing, e.g., it
314 played tricks like "#undef SIGIO" but these tricks were not used
315 consistently. Simplify mostly by not #undeffing standard symbols,
316 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
317 or not as we please) rather than "defined SIGIO" (standard symbol
318 that we probably shouldn't #undef).
319 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
320 Modules that need it can include it.
321 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
322 * dispextern.h (ignore_sigio): New decl.
323 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
324 unconditionally, since it's now a no-op if !USABLE_SIGIO.
325 * emacs.c (shut_down_emacs):
326 * keyboard.c (kbd_buffer_store_event_hold):
327 Use ignore_sigio rather than invoking 'signal' directly.
328 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
330 (FIONREAD, SIGIO): Do not #undef.
331 (tty_read_avail_input): Use #error rather than a syntax error.
332 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
333 for I_PIPE, used by SETUP_SLAVE_PTY.
334 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
335 * sysdep.c (croak): Remove; no longer needed. This bit of
336 temporary code, with Fred N. Fish's comment that it's temporary,
337 has been in Emacs since at least 1992!
338 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
339 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
340 * syssignal.h (croak): Remove decl.
341 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
342 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
343 now that we're termios-only.
344 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
345 * term.c (dissociate_if_controlling_tty): Use #error rather than
348 Work around GCC and GNOME bugs when --enable-gcc-warnings.
349 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
350 to work around GNOME bug 683906.
351 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
352 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
353 This works around GCC bug 54561.
355 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
357 More fixes for 'volatile' and setjmp/longjmp.
358 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
359 * image.c (struct png_load_context) [HAVE_PNG]: New type.
360 (png_load_body) [HAVE_PNG]:
361 (jpeg_load_body) [HAVE_JPEG]:
362 New function, with most of the old parent function's body.
363 (png_load) [HAVE_PNG]:
364 (jpeg_load) [HAVE_JPEG]:
365 Invoke the new function, to avoid longjmp munging our locals.
366 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
367 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
368 longjmp is passed 2, as the C standard doesn't guarantee this.
369 Instead, store the failure code into mgr->failure_code.
371 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
373 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
374 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
375 (syms_of_keyboard): Remove support for unread-command-char.
377 2012-09-12 Eli Zaretskii <eliz@gnu.org>
379 * w32proc.c (sys_kill): If PID is our process ID and the signal is
380 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
381 violation. (Bug#12426)
383 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
385 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
387 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
389 * eval.c: Add `inhibit-debugger'.
390 (Qinhibit_debugger): New symbol.
391 (call_debugger): Bind it instead of Qdebug_on_error.
392 (maybe_call_debugger): Test Vinhibit_debugger.
393 (syms_of_eval): Define inhibit-debugger.
394 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
395 (syms_of_xdisp): Remove inhibit-debug-on-message.
397 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
399 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
400 If a nonvolatile local variable is written before a _longjmp to
401 the frame containing the variable, and is read after the _longjmp,
402 the value read is indeterminate. Some local variables of type
403 'struct handler' and 'struct catchtag' are used in this way, so
404 mark each of their slots as volatile if the slot can be set before
405 _longjmp and read afterwards.
406 * lisp.h (struct handler): var and chosen_clause are now volatile.
407 (struct catchtag): val, next, and pdlcount are now volatile.
409 * bidi.c (bidi_push_it, bidi_pop_it):
410 * fns.c (copy_hash_table):
411 * image.c (define_image_type):
412 * keyboard.c (kbd_buffer_store_event_hold):
413 * process.c (Fprocess_send_eof):
414 * xfaces.c (x_create_gc) [HAVE_NS]:
415 * xgselect.c (xg_select):
416 Prefer assignment to memcpy when either will do.
418 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
419 Use pointer-to-a-pointer to simplify and avoid a NILP check each
420 time an item is removed. No need to mark this function 'inline';
421 the compiler knows better than we do.
423 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
425 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
426 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
427 to change_frame_size (Bug#12388).
428 (windowDidResize:): Pass YES to updateFrameSize.
430 * nsterm.h: Add delay parameter to updateFrameSize.
432 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
434 Discard killed buffers from deleted window and frame objects.
435 This reduces an amount of references to killed buffers and
436 helps GC to reclaim them faster.
437 * alloc.c (discard_killed_buffers): New function.
438 (mark_object): Use it for deleted windows and frames.
439 (mark_object): If symbol's value is set up for a killed buffer
440 or deleted frame, restore it's global binding.
441 * data.c (swap_in_global_binding): Add GC notice.
442 (swap_in_symval_forwarding): Use convenient set_blv_where.
443 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
444 * window.h: ... to here.
446 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
448 Convenient macro to check whether the buffer is live.
449 * buffer.h (BUFFER_LIVE_P): New macro.
450 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
451 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
453 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
455 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
456 composition cases (Bug#12364).
458 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
459 overhang of succeeding glyphs overlapping box cursor.
461 * w32term.c (x_draw_glyph_string): Likewise.
463 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
465 Simplify, document, and port floating-point (Bug#12381).
466 The porting part of this patch fixes bugs on non-IEEE platforms
467 with frexp, ldexp, logb.
468 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
470 * floatfns.c: Simplify discussion of functions that Emacs doesn't
471 support, by removing commented-out code and briefly listing the
472 C89 functions excluded. The commented-out stuff was confusing
473 maintenance, e.g., we thought we needed cbrt but it was commented out.
474 (logb): Remove decl; no longer needed.
475 (isfinite): New macro, if not already supplied.
476 (isnan): Don't replace any existing macro.
477 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
478 are present on all C89 platforms.
479 (Ffrexp): Do not special-case zero, as frexp does the right thing
481 (Flogb): Do not use logb, as it doesn't have the desired meaning
482 on hosts that use non-base-2 floating point. Instead, stick with
483 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
484 frexp, to avoid getting an unspecified result.
486 * xdisp.c (Qinhibit_debug_on_message): Now static.
488 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
490 * nsterm.m (ns_update_begin): Set clip path to whole view by using
491 NSBezierPath (Bug#12131).
493 2012-09-10 Chong Yidong <cyd@gnu.org>
495 * fns.c (Fdelq, Fdelete): Doc fix.
497 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
499 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
500 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
502 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
504 * lisp.h (make_lisp_ptr): New macro to replace XSET.
505 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
508 2012-09-09 Eli Zaretskii <eliz@gnu.org>
510 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
511 left fringe if the window has a left margin. This avoids leaving
512 traces of the cursor because its leftmost pixel is not drawn over.
514 * dispnew.c (update_window_line): When the left margin area of a
515 screen line is updated, set the redraw_fringe_bitmaps_p flag of
516 that screen line. (Bug#12277)
518 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
520 Assume C89 or later for math functions (Bug#12381).
521 This simplifies the code, and makes it a bit smaller and faster,
522 and (most important) makes it easier to clean up signal handling
523 since we can stop worring about floating-point exceptions in
524 library code. That was a problem before C89, but the problem
525 went away many years ago on all practical Emacs targets.
526 * data.c, image.c, lread.c, print.c:
527 Don't include <math.h>; no longer needed.
528 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
529 might be autoconfigured, as that never happens.
531 * doprnt.c (DBL_MAX_10_EXP):
533 Remove. C89 or later always defines these.
534 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
535 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
536 (arith_error, domain_error, domain_error2):
537 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
538 no longer needed -- we simply return what C returns. All uses removed.
539 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
541 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
542 Remove. All uses expanded, as these macros are no longer used
543 more than once and are now more trouble than they're worth.
544 (Ftan): Use tan, not sin / cos.
545 (Flogb): Assume C89 frexp.
546 (fmod_float): Assume C89 fmod.
547 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
548 (init_floatfns): Remove. All uses removed.
550 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
552 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
553 compositeToPoint for OSX < 10.6 (Bug#12390).
555 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
557 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
558 This produces more-accurate results.
560 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
562 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
565 2012-09-08 Chong Yidong <cyd@gnu.org>
567 * syntax.c (Fstring_to_syntax): Doc fix.
569 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
571 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
572 in the internal border.
573 (x_set_window_size): Remove static variables and their usage.
574 (ns_redraw_scroll_bars): Fix NSTRACE arg.
575 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
576 fringe/internal border adjustment (Bug#11052).
577 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
578 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
579 (ns_fix_rect_ibw): Remove.
580 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
581 (ns_dumpglyphs_box_or_relief): Ditto.
582 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
584 (ns_dumpglyphs_image): Ditto.
585 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
587 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
588 their usage. Add fringe_extended_p and its use as in other terms.
589 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
590 scroll bar was removed.
591 (updateFrameSize): New function.
592 (windowDidResize): Move code to updateFrameSize and call it.
594 * nsterm.h (EmacsView): Add updateFrameSize.
596 2012-09-07 Chong Yidong <cyd@gnu.org>
598 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
600 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
602 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
604 More signal-handler cleanup (Bug#12327).
605 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
606 Problem introduced when merging patches. Noted by Eli Zaretskii in
607 <http://bugs.gnu.org/12327#67>.
608 * floatfns.c: Comment fix.
609 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
610 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
611 and anyway the declaration is harmless even if SIGDANGER is not defined.
612 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
613 defined BROKEN_FIONREAD). systty.h formerly did this, but other
614 source files not surprisingly expected syssignal.h to define, or
615 not define, SIGIO, and it's cleaner to do it that way, for consistency.
616 Include <sys/ioctl.h>, for FIONREAD.
617 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
618 This eliminates a problem whereby other files mysteriously had
619 to include "syssignal.h" before including "systty.h" if they
620 wanted to use "#ifdef SIGIO".
622 2012-09-07 Eli Zaretskii <eliz@gnu.org>
624 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
626 * w32.c (sigemptyset): Empty the set.
627 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
629 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
631 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
633 * alloc.c (mark_buffer): Revert unsafe marking optimization.
634 (mark_object): Likewise for frame objects.
636 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
638 * syssignal.h (handle_on_main_thread): Always declare,
639 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
640 This ports to platforms without HAVE_PTHREAD.
642 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
644 Signal-handler cleanup (Bug#12327).
645 Emacs's signal handlers were written in the old 4.2BSD style with
646 sigblock and sigmask and so forth, and this led to some
647 inefficiencies and confusion. Rewrite these to use
648 pthread_sigmask etc. without copying signal sets around. Also,
649 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
650 'signal', and instead use functions that do not attempt to take
651 over the system name space. This patch causes Emacs's text
652 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
653 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
654 Do not include <signal.h> or "syssignal.h", as these
655 modules do not use signals.
656 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
657 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
658 Do not include <signal.h>, as "syssignal.h" does that for us now.
659 * atimer.c (sigmask_atimers): New function.
660 (block_atimers, unblock_atimers): New functions,
661 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
663 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
664 no longer needed here.
665 * emacs.c (main): Inspect existing signal handler with sigaction,
666 so that there's no need to block and unblock SIGHUP.
667 * sysdep.c (struct save_signal): New member 'action', replacing
668 old member 'handler'.
669 (save_signal_handlers, restore_signal_handlers):
670 Use sigaction instead of 'signal' to save and restore.
671 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
672 New function. All users of 'signal' modified to use set_sighandler
673 if they're writeonly, and to use sys_signal if they're read+write.
674 (emacs_sigaction_init, forwarded_signal): New functions.
675 (sys_signal): Remove. All uses replaced by calls to sigaction
676 and emacs_sigaction_init, or by direct calls to 'signal'.
677 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
678 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
679 all uses replaced by pthread_sigmask etc. calls.
680 * syssignal.h: Include <signal.h>.
681 (emacs_sigaction_init, forwarded_signal): New decls.
682 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
683 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
684 (sigmask, sys_sigmask): Remove; no longer needed.
685 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
686 (sigblock, sigunblock, sigfree):
687 (sigsetmask) [!defined sigsetmask]:
688 Remove. All uses replaced by pthread_sigmask.
689 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
690 no longer need to be replaced, and its typical old uses
691 are now done via emacs_sigaction_init and sigaction.
692 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
693 (sys_sigdel): Remove; unused.
694 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
696 2012-09-06 Eli Zaretskii <eliz@gnu.org>
698 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
699 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
701 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
703 Explicitly mark buffer_defaults and buffer_local_symbols.
704 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
705 mark_local_symbols here.
706 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
707 since special buffers aren't marked here any more.
708 (allocate_buffer): Chain new buffer with all_buffers here...
709 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
711 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
712 (syms_of_buffer): Remove staticpro of the above.
713 (init_buffer_once): Set names for buffer_defaults and
714 buffer_local_symbols.
716 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
718 Use bool for booleans in font-related modules.
719 * font.c (font_intern_prop, font_style_to_value)
720 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
721 (generate_otf_features, font_check_otf_features, font_check_otf)
722 (font_match_p, font_list_entities, font_at):
723 * fontset.c (fontset_id_valid_p, reorder_font_vector
724 (fontset_find_font, Fset_fontset_font)
725 (face_suitable_for_char_p) [0]:
726 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
727 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
728 (m17n_flt_initialized, ftfont_shape_by_flt):
729 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
730 * nsfont.m (nsfont_draw):
731 * w32font.c (w32font_draw):
732 * w32term.c (x_draw_glyphless_glyph_string_foreground):
733 Use bool for booleans.
734 * font.h: Adjust to above API changes.
735 (struct font, struct font_driver, struct font_driver_list):
736 Use bool for booleans.
737 (struct font): Remove useless member encoding_type.
739 * fontset.c, xftfont.c: Omit unnecessary static decls.
741 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
743 * alloc.c (mark_object): Revert window marking code
744 since it's unsafe for the Fset_window_configuration.
746 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
748 Fix race conditions with signal handlers and errno (Bug#12327).
749 Be more systematic about preserving errno whenever a signal
750 handler returns, even if it's not in the main thread. Do this by
751 renaming signal handlers to distinguish between signal delivery
752 and signal handling. All uses changed.
753 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
754 * data.c (deliver_arith_signal): Rename from arith_error.
755 * dispnew.c (deliver_window_change_signal): Rename from
756 window_change_signal.
757 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
758 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
759 * keyboard.c (deliver_input_available_signal): Rename from
760 input_available_signal.
761 (deliver_user_signal): Rename from handle_user_signal.
762 (deliver_interrupt_signal): Rename from interrupt_signal.
763 * process.c (deliver_pipe_signal): Rename from send_process_trap.
764 (deliver_child_signal): Rename from sigchld_handler.
765 * atimer.c (handle_alarm_signal):
766 * data.c (handle_arith_signal):
767 * dispnew.c (handle_window_change_signal):
768 * emacs.c (handle_fatal_signal, handle_danger_signal):
769 * keyboard.c (handle_input_available_signal):
770 * keyboard.c (handle_user_signal, handle_interrupt_signal):
771 * process.c (handle_pipe_signal, handle_child_signal):
772 New functions, with the actual signal-handling code taken from the
773 original respective signal handlers, sans the sporadic attempts to
774 preserve errno, since that's now done by handle_on_main_thread.
775 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
776 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
777 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
779 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
780 Move initialization of main_thread to sysdep.c's init_signals.
781 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
782 our usage, and simplifies the mainline code.
783 (record_child_status_change): New static function, as a helper
784 for handle_child_signal, and with most of the old child handler's
786 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
787 (handle_child_signal): Use the above.
788 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
789 Moved here from emacs.c.
790 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
791 code moved here from emacs.c's main function.
792 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
793 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
794 lets callers save and restore errno properly.
796 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
798 Remove redundant or unused things here and there.
799 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
800 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
801 * editfns.c (Fcompare_buffer_substrings): Likewise.
802 * frame.h (struct terminal, struct font_driver_list):
803 Remove redundant declarations.
804 * window.h (Qleft, Qright): Likewise.
806 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
808 Do not mark objects from deleted buffers, windows and frames.
809 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
810 (mark_object): Likewise for windows and frames.
812 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
814 * alloc.c (valid_lisp_object_p): Treat killed buffers,
815 buffer_defaults and buffer_local_symbols as valid objects.
816 Return special value to denote them.
818 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
820 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
821 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
822 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
823 (file_name_absolute_p, Fsubstitute_in_file_name):
824 (check_executable, check_writable, Ffile_accessible_directory_p)
825 (Fset_file_selinux_context, Fdefault_file_modes)
826 (Finsert_file_contents, choose_write_coding_system)
827 (Fwrite_region, build_annotations, a_write, e_write)
829 * filelock.c (boot_time_initialized, get_boot_time)
830 (get_boot_time_1, lock_file_1, within_one_second):
831 * floatfns.c (in_float):
832 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
833 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
834 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
835 * lisp.h (struct Lisp_Hash_Table.cmpfn):
836 * window.c (compare_window_configurations):
837 Use bool for booleans.
838 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
839 (Fdefault_file_modes): Now mode_t, not int, for modes.
840 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
841 (internal_delete_file): Now returns void, not a (boolean) int,
842 since nobody was looking at the return value.
843 * lisp.h, window.h: Adjust to above API changes.
845 * xdisp.c (set_message): Simplify and reindent last change.
847 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
849 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
851 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
853 * eval.c (call_debugger): Make the function non-static so that we
854 can call it from set_message.
856 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
857 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
859 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
861 Give more-useful info on a fatal error (Bug#12328).
862 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
863 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
864 of doing the work ourselves.
865 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
867 (fatal_error_backtrace): New function, taken from the guts
868 of the old fatal_error_signal, but with a new option to output
870 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
871 info about the signal than just its number.
872 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
873 * sysdep.c: Include <execinfo.h>
874 (emacs_backtrace): New function, taken partly from the previous
875 code of the 'die' function.
876 (emacs_abort): Call fatal_error_backtrace rather than abort.
878 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
880 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
881 eager (load-time) macro-expansion.
882 * lisp.mk (lisp): Add macroexp.
884 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
886 Simplify redefinition of 'abort' (Bug#12316).
887 Do not try to redefine the 'abort' function. Instead, redo
888 the code so that it calls 'emacs_abort' rather than 'abort'.
889 This removes the need for the NO_ABORT configure-time macro
890 and makes it easier to change the abort code to do a backtrace.
891 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
892 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
893 Remove; sysdep.c's emacs_abort now takes its place.
894 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
895 'abort' changed to use 'emacs_abort'.
896 * msdos.c (dos_abort) [defined abort]: Remove; not used.
897 (abort) [!defined abort]: Rename to ...
898 (emacs_abort): ... new name.
899 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
900 the place of the old 'abort' in emacs.c.
901 * w32.c, w32fns.c (abort): Do not #undef.
902 * w32.c (emacs_abort): Rename from w32_abort.
904 2012-09-04 Eli Zaretskii <eliz@gnu.org>
906 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
907 offsets[j].dv, since the y axis of the screen coordinates points
908 down, while the y axis of the font definition coordinates points
909 up. This fixes display of Arabic diacritics such as KASRA and
910 KASRATAN. (Bug#11860)
912 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
914 Be more systematic about _setjmp vs setjmp.
915 * alloc.c (test_setjmp, mark_stack):
916 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
917 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
918 (png_load, my_error_exit, jpeg_load):
919 * process.c (send_process_trap, send_process):
920 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
921 The underscored versions are up to 30x faster on some hosts.
922 Formerly, the code used setjmp+longjmp sometimes and
923 _setjmp+_longjmp at other times, with no particular reason to
924 prefer setjmp+longjmp.
926 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
928 Fix minor problem found by static checking.
929 * buffer.c (Fdelete_all_overlays): Return nil.
931 2012-09-03 Martin Rudalics <rudalics@gmx.at>
933 * buffer.c (Fdelete_all_overlays): New function.
935 2012-09-03 Chong Yidong <cyd@gnu.org>
937 * gtkutil.c: Add extern decl for Qxft.

955 EXCLUDE_SUBRS_P. All callers changed.
956 * dispextern.h, lisp.h: Reflect above API changes.
957 * firstfile.c (dummy): Use the address of 'main', whose signature
958 won't change, instead of the address of 'initialize', whose
959 signature just changed from int to bool.

961 * msdos.c (fatal_error_in_progress): ... from here.
962 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead

965 REDISPLAYING_P when unwinding, instead of saving its previous,
966 always-false value and then restoring it.
968 Clean up some extern decls.
969 Mostly, this hoists extern decls out of .c files and into .h files.
970 That way, we're more likely to catch errors if the interfaces change.

997 * xfaces.c: Remove unnecessary static decls.
998 * xterm.c (updating_frame): Remove decl of nonexistent object.
1000 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
1001 when building globals.h, as the objects that are not built on
1002 this host are not needed to compile C files on this host.
1004 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>

1056 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
1057 more than one grapheme cluster passed to the shaper: compute the
1058 offset adjustment values separately for each cluster. (Bug#11860)
1060 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1061 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1062 about implicit conversions from integer to pointer.
1064 2012-09-01 Daniel Colascione <dancol@dancol.org>
1066 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

1120 window system declarations.
1122 * frame.h: Move common functions here: set_frame_menubar,
1123 x_set_window_size, x_sync, x_get_focus_frame,
1124 x_set_mouse_position, x_set_mouse_pixel_position,
1125 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

1211 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
1212 Add window_closed and button_values. Add void as return value for
1213 add(Button|String|Split). addButton takes int instead of Lisp_Object.
1214 Add process_dialog as new member.

1385 detection of uninitialized objects from spare memory as live.
1387 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
1390 * Makefile.in (.PHONY): versioclean -> versionclean.
1392 Remove unused external symbols.
1393 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
1394 * window.c (Qwindow_valid_p, decode_valid_window):
1395 Now static, not extern.
1396 * data.c (Qinterval): Remove; unused.
1397 (syms_of_data): Do not define 'interval'.
1398 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
1399 * window.h (decode_valid_window):
1402 * character.c, charset.c, chartab.c: Use bool for booleans.
1403 * character.c (lisp_string_width, string_count_byte8)
1404 (string_escape_byte8):
1405 * charset.c (charset_map_loaded, load_charset_map, read_hex):
1406 (load_charset_map_from_file, map_charset_chars)
1407 (Fdefine_charset_internal, define_charset_internal)
1408 (Fdeclare_equiv_charset, find_charsets_in_text)
1409 (Ffind_charset_region, char_charset, Fiso_charset):
1410 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
1411 (sub_char_table_set, sub_char_table_set_range)
1412 (char_table_set_range, optimize_sub_char_table)
1413 (map_sub_char_table):
1414 Use bool for boolean.
1415 * character.c (str_to_unibyte): Omit last boolean argument; it was
1416 always 0. All callers changed.
1417 * character.h, charset.h: Adjust to match previous changes.
1418 * character.h (char_printable_p): Remove decl of nonexistent function.
1419 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
1420 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
1421 are all boolean, so make them single-bit bitfields.
1423 * lisp.h (ASET): Remove attempt to detect side effects.
1424 It was meant to be temporary and it often doesn't work,
1425 because when IDX has side effects the behavior of IDX==IDX
1426 is undefined. See Stefan Monnier in
1427 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
1429 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
1431 * lisp.h (functionp): New function (extracted from Ffunctionp).
1432 (FUNCTIONP): Use it.
1433 * eval.c (Ffunctionp): Use it.
1435 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1437 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
1438 as that's faster and simpler than static storage. Don't bother
1439 with the g_main_context_query overhead if g_main_context_pending
1440 says no events are pending.
1441 (gfds, gfds_size): Remove these static vars.
1442 (xgselect_initialize): Remove; no longer needed.
1443 All uses and decls removed.
1445 * emacs.c (fatal_error_signal_hook): Remove.
1446 All uses removed. This leftover from old code was always 0.
1448 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
1449 * casefiddle.c (casify_object, casify_region):
1450 * casetab.c (set_case_table):
1451 * category.c, category.h (word_boundary_p):
1452 * category.h (CHAR_HAS_CATEGORY):
1453 Use bool for booleans, instead of int.
1455 2012-08-25 Eli Zaretskii <eliz@gnu.org>
1457 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
1459 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1461 On assertion failure, print backtrace if available.
1462 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1463 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1464 * Makefile.in (LIB_EXECINFO): New macro.
1467 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1468 * bytecode.c (exec_byte_code):
1469 * callint.c (check_mark, Fcall_interactively):
1470 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1471 (getenv_internal, sync_process_alive, call_process_exited):
1472 * lisp.h (USE_SAFE_ALLOCA):
1473 Use bool for booleans, instead of int.
1474 * lisp.h, process.h: Adjust prototypes to match above changes.
1475 * callint.c (Fcall_interactively): Don't assume the mark's
1476 offset fits in 'int'.
1478 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1480 * buffer.c, buffer.h: Use bool for boolean.
1481 * buffer.c (reset_buffer_local_variables)
1482 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1483 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
1484 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
1485 (overlay_touches_p, overlay_strings, Foverlay_put)
1486 (report_overlay_modification, call_overlay_mod_hooks):
1487 (mmap_enlarge, mmap_set_vars):
1488 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1489 Use bool for booleans, instead of int.
1490 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1491 since the 1-or-0 return value is always ignored anyway.
1492 (mmap_initialized_p):
1493 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1494 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1496 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1498 * bidi.c: Use bool for boolean.
1499 This is a bit more readable, and makes the text segment of bidi.o
1500 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1501 Presumably it's faster too.
1502 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1504 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1505 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1506 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1507 (bidi_explicit_dir_char, bidi_level_of_next_char)
1508 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1509 Use bool for booleans, instead of int.
1510 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1511 (bidi_unshelve_cache): Adjust decls to match code.
1513 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1515 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1518 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1520 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1521 * atimer.h: Include <stdbool.h>.
1523 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1525 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1526 compile time tests instead of run time tests on systems that do
1528 (FRAME_MAC_P): Remove leftover from deleted code.
1529 * frame.c (syms_of_frame): Remove leftover from deleted code.
1531 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
1533 * nsterm.m (insertText:): Don't clear modifiers if code is space.
1535 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1537 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1538 Otherwise, the compiler complains about (A?B:C) where B is void
1539 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1540 (fontset_add): Return void, for FONTSET_ADD.
1542 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1544 * alloc.c: Use bool for booleans.
1545 (gc_in_progress, abort_on_gc)
1546 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1547 (dont_register_blocks) [GC_MALLOC_CHECK]:
1548 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1549 (check_string_bytes, make_specified_string, memory_full)
1550 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1551 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1552 (mark_stack, valid_pointer_p, make_pure_string)
1553 (Fgarbage_collect, survives_gc_p, gc_sweep):
1554 Use bool for booleans, instead of int.
1555 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1556 Remove unused local.
1557 * alloc.c (PURE_POINTER_P):
1558 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1559 * editfns.c (Fformat):
1560 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1562 * fns.c (sweep_weak_table):
1563 * lisp.h (suppress_checking, push_message, survives_gc_p)
1564 (make_pure_string, gc_in_progress, abort_on_gc):
1565 * lread.c (readchar, read1):
1566 * print.c (Fprin1_to_string):
1567 * xdisp.c (push_message):
1568 Use bool for booleans affected directly or indirectly by
1571 Make recently-introduced setters macros.
1572 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1573 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1574 (set_fontset_default, set_fontset_fallback): Rename from their
1575 upper-case counterparts, and make them functions rather than macros.
1576 This is more consistent with the other recently-introduced setters.
1577 These don't need to be inline, since they're local.
1579 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1581 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1582 the loop (Bug#12247).
1584 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1586 * lisp.h (vcopy): Use memcpy rather than our own loop.
1587 This fixes a performance regression introduced by the recent
1588 addition of vcopy. This means 'vcopy' will need to be modified
1589 for a copying collector, but that's OK. Also, tighten the
1590 checking in the assertion.
1592 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1594 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1595 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1596 non-base glyph for the width of the base character, according to
1597 what x_draw_composite_glyph_string_foreground expects.
1598 Generate WADJUST value according to composition_gstring_width's
1599 expectations, to produce correct width of the composed character.
1600 Reverse the sign of the DU offset produced by ScriptPlace.
1602 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1604 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1606 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1608 Avoid direct writes to contents member of struct Lisp_Vector.
1609 * lisp.h (vcopy): New function to copy data into vector.
1610 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
1611 * fns.c (Ffillarray): Use ASET.
1612 * keyboard.c (timer_check_2): Use AREF and ASET.
1613 (append_tool_bar_item, Frecent_keys): Use vcopy.
1614 * lread.c (read_vector): Use ASET.
1615 * msdos.c (Frecent_doskeys): Use vcopy.
1616 * xface.c (Finternal_copy_lisp_face): Use vcopy.
1617 (Finternal_merge_in_global_face): Use ASET and vcopy.
1618 * xfont.c (xfont_list_pattern): Likewise.
1620 2012-08-21 Martin Rudalics <rudalics@gmx.at>
1622 * window.c (Fwindow_point): For the selected window always return
1623 the position of its buffer's point.
1624 (Fset_window_point): For the selected window always go in its
1625 buffer to the specified position.
1627 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1629 Setter macros for fontsets.
1630 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1631 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1632 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1635 2012-08-20 Glenn Morris <rgm@gnu.org>
1637 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1638 Don't assume that `ln -f' works.
1640 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1642 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1643 and later about non-assignments with no effect. See discussion at
1644 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1647 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1649 Inline setter functions for Lisp_Objects slots of struct specbinding.
1650 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
1653 2012-08-20 Martin Rudalics <rudalics@gmx.at>
1655 * window.c (select_window): Always make selected window's buffer
1658 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1660 Use AREF and ASET for docstrings of category tables.
1661 * category.h (CATEGORY_DOCSTRING): Use AREF.
1662 (SET_CATEGORY_DOCSTRING): Use ASET.
1663 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
1665 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1667 Inline setter functions for hash table members.
1668 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
1669 (set_hash_hash, set_hash_index): Rename with _slot suffix.
1670 (set_hash_key_and_value, set_hash_index, set_hash_next)
1671 (set_hash_hash): New functions.
1672 * charset.c, fns.c: Adjust users.
1674 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1676 Inline getter and setter functions for per-buffer values.
1677 * buffer.h (per_buffer_default, set_per_buffer_default)
1678 (per_buffer_value, set_per_buffer_value): New functions.
1679 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
1680 * buffer.c, data.c: Adjust users.
1682 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
1684 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
1686 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
1688 Rely on <config.h> + <unistd.h> to declare 'environ',
1689 as gnulib does this if the system doesn't.
1690 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
1691 Remove declaration. MS-Windows declares it on stdlib.h which is
1692 included by conf_post.h.
1693 * emacs.c (environ) [DOUG_LEA_MALLOC]:
1694 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
1695 * vm-limit.c: Include <unistd.h>, for 'environ'.
1697 * unexaix.c, unexcoff.c: Include "mem-limits.h".
1698 (start_of_data): Remove decl; mem-limits.h provides it.
1700 * xdisp.c (handle_invisible_prop): Make it a bit faster
1701 and avoid a gcc -Wmaybe-uninitialized diagnostic.
1703 2012-08-19 Chong Yidong <cyd@gnu.org>
1705 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
1708 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
1710 * .gdbinit: Use call instead of set when calling a function in the
1713 * data.c (set_internal): Don't use set_blv_found.
1714 (Fkill_local_variable): Likewise.
1716 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
1718 * nsfont.m (ns_ascii_average_width): Ensure the string
1719 ascii_printable is initialized with a null-terminated character
1720 array. Otherwise, it can contain undesired extra characters.
1722 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1724 port new setting code to Sun C 5.8 2005/10/13
1725 * chartab.c, lisp.h (char_table_set, char_table_set_range):
1726 Return void, not Lisp_Object. Otherwise, the compiler
1727 complains about (A?B:C) where B is void and C is Lisp_Object
1728 when compiling CHAR_TABLE_SET, due to the recent change to
1729 the API of sub_char_table_set_contents.
1731 2012-08-18 Chong Yidong <cyd@gnu.org>
1733 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
1734 for the string case (Bug#3874).
1736 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1738 * buffer.h (BSET): Remove (Bug#12215).
1739 Replace all uses with calls to new setter functions.

1769 New setter functions.
1771 * process.h (PSET): Remove (Bug#12215).

1786 * window.h (WSET): Remove (Bug#12215).
1787 Replace all uses with calls to new setter functions.
1788 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
1789 (WINDOW_INLINE): New macro.

1808 New setter functions.
1810 * termhooks.h (TSET): Remove (Bug#12215).
1811 Replace all uses with calls to new setter functions.
1812 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
1813 (TERMHOOKS_INLINE): New macro.
1814 (tset_charset_list, tset_selection_alist): New setter functions.
1815 * terminal.c (TERMHOOKS_INLINE):

2566 value of EMACSLOADPATH, as it is no longer needed.
2567 (check_windows_init_file): Now external, not static.

2573 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

2618 * alloc.c (record_xmalloc): New function.
2619 * lisp.h (record_xmalloc): New decl.
2620 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts

2622 needed. All uses changed.
2623 * print.c (print_string, print_error_message): Avoid length recalc.
2625 Improve fix for macroexp crash with debugging (Bug#12118).
2626 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
2627 ARRAY_MARK_FLAG when checking subscripts, because ASET is

2660 with addition of handling of symlinks and support for 'lstat'.
2661 If possible, get file's attributes and security information by
2662 handle, not by name. Produce S_IFLNK bit for symlinks, when
2663 called from 'lstat'.
2664 (stat, lstat): New functions, call 'stat_worker'.
2665 (symlink, readlink, careadlinkat): Rewritten to create and resolve
2666 symlinks when the underlying filesystem supports them.
2668 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
2670 Fix macroexp crash on Windows with debugging (Bug#12118).
2671 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
2672 checking subscripts; problem introduced with the recent
2673 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
2674 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
2675 since it's used in non-static inline functions now.
2677 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
2678 Don't assume buffer size fits in 'int'. Remove unused local.

3166 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
3168 Improve GDB symbol export (Bug#12036).
3169 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
3170 arms of an 'if', not using conditional expressions; otherwise GDB
3171 complains about the types in the unevaluated arm when the argument
3172 is an integer literal.
3173 (xgetint): Simplify expression.
3174 * alloc.c (gdb_make_enums_visible): New constant. This ports to
3175 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
3176 Zaretskii in <http://bugs.gnu.org/12036#13>.
3177 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
3178 needed now that we have gdb_make_enums_visible.
3179 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
3180 (enum enum_USE_LSB_TAG):
3181 New enum types, packaging up enums that need to be exported to GDB.
3183 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3185 Utility function to make a list from specified amount of objects.

3200 * xfns.c (syms_of_xfns): Likewise.
3202 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3204 Fast save_excursion_save and save_excursion_restore.
3205 * lisp.h (struct Lisp_Excursion): New data type.
3206 (PVEC_EXCURSION): New pseudovector type.
3207 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
3208 to deal with it. Adjust comments.
3209 (init_marker, attach_marker): New prototype.
3210 (unchain_marker): Adjust prototype.
3211 * marker.c (attach_marker): Change to global.

3219 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
3221 Fix export of symbols to GDB (Bug#12036).
3222 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
3223 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
3224 emacs.c, as this is a more-suitable home. Had this been done earlier
3225 the fix for 12036 would have avoided some of the problems noted in
3226 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
3227 would have been more obvious.
3228 * emacs.c: Do not include <verify.h>; no longer needed.
3229 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
3230 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
3231 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3232 Remove; now done in lisp.h.
3233 * lisp.h (PUBLISH_TO_GDB): New macro.
3234 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
3235 (DATA_SEG_BITS): Use it.
3236 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
3237 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3238 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3239 not be usable in #if. This simplifies things.
3241 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
3243 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
3245 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
3247 Simplify export of symbols to GDB (Bug#12036).
3248 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3249 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3250 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3251 Adjust to changes in lisp.h and emacs.c, by using
3252 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
3253 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
3254 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
3255 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
3256 instead of gdb_valbits.
3257 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
3258 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
3259 instead of gdb_array_mark_flag.
3260 (xboolvector): Get size from $->size, not $->header.size.
3261 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
3262 (xreload, hook-run, hookpost-run): Remove.
3263 * emacs.c: Include <verify.h>.
3264 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
3265 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
3267 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
3268 (gdb_USE_LSB_TAG): New enum constants.
3269 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3270 Also define these as enum constants, so they're visible to GDB.
3271 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
3272 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
3273 as constants, so they're visible to GDB.
3274 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
3275 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
3276 Now enum constants, not macros, so they're visible to GDB.
3277 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
3278 more convenient now. All uses changed.
3279 (VALMASK) [USE_LSB_TAG]: Also define in this case.
3280 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
3282 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

3287 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
3289 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
3290 add argument, tune behavior, and adjust all callers.
3292 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
3294 Use typedef for EMACS_INT, EMACS_UINT.
3295 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
3296 than macros. This simplifies debugging in the usual case, since
3297 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
3298 and it allows expressions involving EMACS_INT casts.
3299 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
3301 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
3303 * nsterm.m (ns_read_socket): Return early if there is a modal

3311 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
3313 Adjust buffer text indirection counters at the end of Fkill_buffer.
3314 * buffer.c (Fkill_buffer): Adjust indirection counters when the
3315 buffer is definitely dead. This should really fix an issue reported
3316 by Christoph Scholtes again. (Bug#12007).
3317 (init_buffer_once): Initialize indirection counters of
3318 buffer_defaults and buffer_local_symbols (for sanity and safety).
3320 2012-07-24 Eli Zaretskii <eliz@gnu.org>
3322 * xdisp.c (init_iterator): Don't compute dimensions of truncation
3323 and continuation glyphs on tooltip frames, leave them at zero.
3324 Avoids continued lines in tooltips. (Bug#11832)
3326 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

3351 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3353 Swap buffer text indirection counters in Fbuffer_swap_text.
3354 * buffer.c (Fbuffer_swap_text): Swap indirections too.
3355 This avoids crash reported by Christoph Scholtes at
3356 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
3358 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
3360 * nsmenu.m (Popdown_data): New struct.
3361 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
3363 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

3365 and autorelease them. Also autorelease img and matrix (Bug#12005).
3366 (dealloc): Remove (Bug#12005).

3383 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
3385 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
3386 as it's limited by the amount of memory, not by INT_MAX.
3388 2012-07-21 Eli Zaretskii <eliz@gnu.org>
3390 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
3391 in special-event-map. See the discussion at

3450 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
3451 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
3452 Adjust users accordingly.

3471 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
3472 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
3473 'for_each_per_buffer_object_at'.
3474 All uses changed. It's better to use upper-case for macros that
3475 cannot be implemented as functions, to give the reader a clue
3476 that they're special.
3478 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
3480 * alloc.c (Fgarbage_collect): Tweak docstring.

3521 * intervals.c (merge_interval_right, merge_interval_left):
3522 Do not zero out this interval if it is absorbed by its children,
3523 as this interval's total length doesn't change in that case. See
3524 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
3526 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
3528 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
3529 when invoking (make-bool-vector N t) and N is a positive

3532 Remove some struct layout assumptions in bool vectors.
3533 * alloc.c (bool_header_size): New constant.
3534 (header_size, word_size): Move earlier, as they're now used earlier.

3537 padding before the data member of a bool vector.
3538 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
3539 than doing the check by hand with an abort ().
3541 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3543 * eval.c (Fdefvar): Don't check constants since we only set the var if
3544 it's not yet defined anyway (bug#11904).
3546 * lisp.h (last_undo_boundary): Declare new var.
3547 * keyboard.c (command_loop_1): Set it.
3548 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
3549 were auto-added by the command loop (bug#11774).
3551 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
3553 * w32font.c (Qsymbol): Remove local definition.

4042 2012-07-11 Glenn Morris <rgm@gnu.org>
4044 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
4045 since nothing has defined it on these platforms.
4047 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
4048 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

4052 Move CLASH_DETECTION to configure.
4054 * s/gnu.h: Remove file, which is now empty.
4056 * s/gnu.h, s/gnu-linux.h:
4057 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
4059 2012-07-11 John Wiegley <johnw@newartisans.com>
4061 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
4062 function attribute, so we only use it if it exists in the
4065 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
4067 Avoid call to strlen in fast_c_string_match_ignore_case.
4068 * search.c (fast_c_string_match_ignore_case): Change to use
4069 length argument. Adjust users accordingly.
4070 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
4072 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

4089 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
4091 Avoid calls to strlen in font processing functions.

4093 (font_open_by_name): Change to use length argument.
4094 Adjust users accordingly.
4095 * font.h (font_open_by_name, font_parse_xlfd, font_unparse_xlfd):
4097 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
4098 Change to return ptrdiff_t.
4099 (xfont_list_pattern, xfont_match): Use length returned by
4100 xfont_decode_coding_xlfd.

4111 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
4113 Remove "#define unix" that is no longer needed (Bug#11905).
4114 * s/aix4-2.h (unix): Remove; no longer needed.
4116 EMACS_TIME simplification (Bug#11875).
4117 This replaces macros (which typically do not work in GDB)
4118 with functions, typedefs and enums, making the code easier to debug.
4119 The functional style also makes code easier to read and maintain.
4120 * systime.h: Include <sys/time.h> on all hosts, not just if
4121 WINDOWSNT, since 'struct timeval' is needed in general.
4122 (EMACS_TIME): Now a typedef, not a macro.
4123 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
4125 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

4127 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
4128 (EMACS_TIME_LE): Now functions, not macros.
4129 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
4130 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
4131 which are not functions. All uses rewritten to use:
4132 (make_emacs_time): New function.
4133 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
4134 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4135 not functions. All uses rewritten to use the following, respectively:
4136 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
4137 (add_emacs_time, sub_emacs_time): New functions.
4138 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
4139 * fileio.c (Fcopy_file):
4140 * xterm.c (XTflash): Get the current time closer to when it's used.
4141 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

4147 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
4148 * frame.c (Fmake_terminal_frame):
4149 * gtkutil.c (get_utf8_string):
4151 * nsmenu.m (ns_update_menubar):
4152 * regex.c (regerror):
4153 Prefer memcpy to strncpy and strncat when either will do.
4154 * fileio.c (Fsubstitute_in_file_name):
4155 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
4156 (menu_separator_name_p):
4157 * nsmenu.m (ns_update_menubar):
4158 Prefer memcmp to strncmp when either will do.
4159 * nsterm.m: Include <ftoastr.h>.
4161 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
4162 Prefer snprintf to strncpy.
4163 * nsterm.m (ns_term_init):
4164 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4165 * nsterm.m (ns_term_init):
4166 Avoid the need for strncpy, by using build_string or
4167 make_unibyte_string directly. Use dtoastr, not snprintf.
4168 * process.c (Fmake_network_process): Diagnose service names that
4169 are too long, rather than silently truncating them or creating
4170 non-null-terminated names.
4171 (Fnetwork_interface_info): Likewise, for interface names.
4172 * sysdep.c (system_process_attributes) [GNU_LINUX]:
4173 Prefer sprintf to strncat.
4174 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
4175 Prefer vsnprintf to vsprintf + strncpy.
4177 2012-07-10 Glenn Morris <rgm@gnu.org>
4179 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
4180 Clarify fallback case.
4182 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4184 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
4185 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
4186 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
4187 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
4188 where argument type is known to be a Lisp_Cons.
4190 2012-07-10 Tom Tromey <tromey@redhat.com>
4192 * bytecode.c (BYTE_CODE_THREADED): New macro.
4193 (BYTE_CODES): New macro. Replaces all old byte-code defines.
4194 (enum byte_code_op): New type.

4198 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4200 Optimize pure C strings initialization.
4201 * lisp.h (make_pure_string): Fix prototype.
4202 (build_pure_c_string): New function, defined as static inline. This
4203 provides a better opportunity to optimize away calls to strlen when
4204 the function is called with compile-time constant argument.
4205 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
4206 argument, adjust users accordingly. Use build_pure_c_string where
4208 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
4209 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
4210 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
4212 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4214 Avoid calls to strlen in miscellaneous functions.
4215 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
4216 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
4217 * lread.c (openp): Likewise.
4219 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4221 Avoid calls to strlen in path processing functions.
4222 * fileio.c (file_name_as_directory): Add comment. Change to add
4223 srclen argument and return the length of result. Adjust users
4225 (directory_file_name): Fix comment. Change to add srclen argument,
4226 swap 1st and 2nd arguments to obey the common convention.
4227 Adjust users accordingly.
4228 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
4230 2012-07-10 Glenn Morris <rgm@gnu.org>
4232 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
4233 Move PENDING_OUTPUT_COUNT definition to configure.
4235 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
4236 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
4237 * s/gnu.h (DATA_START): Move definitions to configure.
4239 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
4240 We include usg5-4-common.h, which defines them both.
4242 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
4243 O_RDONLY already includes it).
4245 Stop ns builds setting the EMACSLOADPATH environment variable.
4246 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4247 Now it does not set EMACSLOADPATH, just returns the load-path string.
4248 * nsterm.h: Update accordingly.
4249 * lread.c [HAVE_NS]: Include nsterm.h.
4250 (init_lread) [HAVE_NS]: Use ns_load_path.
4251 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
4253 2012-07-09 Glenn Morris <rgm@gnu.org>
4255 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
4256 since the included bsd-common.h does so.
4258 Stop ns builds setting the EMACSPATH environment variable.
4259 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
4260 (ns_init_paths): Do not set EMACSPATH.
4261 * nsterm.h (ns_exec_path): Add it.
4262 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
4265 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
4267 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
4269 * process.c (wait_reading_process_output): 'waitchannels' was unset
4270 when read_kbd || !NILP (wait_for_cell); fix this.
4272 Add GCC-style 'const' attribute to functions that can use it.
4273 * character.h (char_resolve_modifier_mask):
4274 * keyboard.h (make_ctrl_char):
4275 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
4276 (init_character_once, next_almost_prime, init_fns, init_image)
4277 (flush_pending_output, init_sound):
4278 * mem-limits.h (start_of_data):

4282 Declare the dummy function with ATTRIBUTE_CONST.
4283 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
4284 Add decls with ATTRIBUTE_CONST.
4286 Minor improvements to make_formatted_string.
4287 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
4288 where int is good enough, as vsprintf returns an int.
4289 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
4291 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4293 Use make_formatted_string to avoid double length calculation.
4294 * lisp.h (make_formatted_string): New prototype.
4295 * alloc.c (make_formatted_string): New function.

4300 * frame.c (make_terminal_frame, set_term_frame_name)
4301 (x_report_frame_params): Likewise.
4302 * image.c (gs_load): Likewise.
4303 * minibuf.c (get_minibuffer): Likewise.

4318 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4320 Move marker debugging code under MARKER_DEBUG.
4321 * marker.c (MARKER_DEBUG): Move marker debugging code under
4322 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4323 for bootstrap with --enable-checking (~3x slowdown reported
4324 by Juanma Barranquero <lekktu@gmail.com>).
4325 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4327 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4329 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
4330 See <http://bugs.gnu.org/11825#29>.
4332 2012-07-08 Eli Zaretskii <eliz@gnu.org>
4334 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4335 has no font, use the frame's font. (Bug#11813)
4336 (display_line): Add commentary about displaying truncation glyphs
4338 (produce_special_glyphs): Move here from term.c.
4340 * term.c (produce_special_glyphs): Move to xdisp.c.
4342 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4345 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4347 * xdisp.c (display_line): Avoid warning about implicit declaration
4350 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4352 * lisp.h: Remove empty conditional.
4354 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4356 * lread.c (load_path_check): Now static.
4358 Fix some minor --with-ns problems found by static checking.
4359 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
4360 (x_set_font) [!HAVE_X_WINDOWS]:
4361 * image.c (xpm_load_image) [HAVE_NS]:
4362 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4363 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4364 Remove unused local.
4365 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
4366 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
4367 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
4368 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
4369 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
4370 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
4371 Fix pointer signedness problem.
4372 * xfaces.c (FRAME_X_FONT_TABLE):
4373 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
4375 2012-07-07 Glenn Morris <rgm@gnu.org>
4377 * lread.c (load_path_check): New function, split from init_lread.
4378 (init_lread): Reorganize. Motivation:
4379 If EMACSLOADPATH is set, check/warn about that rather than the
4380 defaults, which we are not going to use. Hence we can remove
4381 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4382 Don't warn if site-lisp directories are missing.
4383 If not installed, start from a blank load-path, since
4384 PATH_LOADSEARCH refers to the eventual installation directories.
4386 2012-07-07 Eli Zaretskii <eliz@gnu.org>
4388 Support truncation and continuation glyphs on GUI frames, when
4389 fringes are disabled. (Bug#11832)
4390 * xdisp.c (init_iterator): Get dimensions of truncation and
4391 continuation glyphs even if on GUI frames.
4392 Adjust it->last_visible_x on GUI frames when the left or right fringes,
4393 or both, are absent.
4394 (start_display, move_it_in_display_line_to): Handle the case of a
4395 GUI frame without a fringe to display continuation or truncation
4397 (insert_left_trunc_glyphs): Support GUI frames: make sure
4398 truncation glyphs overwrite enough glyphs from the current line to
4399 have sufficient space in pixels.
4400 (display_line): Support truncation and continuation glyphs on GUI
4401 frames. If some spare pixels are left on the line after inserting
4402 the truncation glyphs, fill that space with a stretch glyph of a
4403 suitably computed width.
4405 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4406 produce_glyphs, to support GUI sessions.
4408 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4410 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4412 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4414 Do not require float-time's arg to fit in time_t (Bug#11825).
4415 This works better on hosts where time_t is unsigned, and where
4416 float-time is applied to the (negative) difference between two times.
4417 * editfns.c (decode_time_components): Last arg is now double *,
4418 not int *, and means to store all the result as a double, without
4419 worrying about whether the seconds part fits in time_t.
4420 All callers changed.
4421 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4422 All callers changed.
4423 (Ffloat_time): Do not fail merely because the specified time falls
4424 outside of time_t range.
4426 2012-07-07 Glenn Morris <rgm@gnu.org>
4428 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

4432 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
4434 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
4435 Update dependencies.
4437 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
4439 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4441 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
4442 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
4443 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
4444 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
4445 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
4446 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
4448 * xfont.c (compare_font_names): Redo to omit the need for casts.
4450 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4452 * xfns.c (Fx_change_window_property): Doc fix.
4453 * w32fns.c (Fx_change_window_property): Doc fix.
4455 * w32fns.c (Fx_window_property): Accept the same arguments as the
4456 X Windows version. Doc fix.
4457 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4459 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4460 Eli Zaretskii <eliz@gnu.org>
4462 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4463 Windows-specific code from nt/config.nt moved here.
4464 Obsolete settings removed.
4466 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4468 * process.c: Avoid unnecessary calls to gettime.
4469 (wait_reading_process_output): Don't get the time of day
4470 when gobbling data immediately and not waiting, as there's no need
4471 for it in that case. This removes a FIXME.
4473 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4475 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4476 is defined (Bug#11768).
4478 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4480 Fix marker debugging code.
4481 * marker.c (byte_char_debug_check): Do not perform the check
4482 if buffer is not multibyte.
4483 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4484 Call byte_char_debug_check with correct arguments.
4486 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4488 Compile marker debugging code only if ENABLE_CHECKING is defined.
4489 * marker.c (byte_char_debug_check, count_markers):
4490 Use only if ENABLE_CHECKING is defined.
4491 (byte_debug_flag): Remove.
4492 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4493 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4495 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4497 Avoid code repetition in marker-related functions.
4498 * marker.c (attach_marker): New function.
4499 (Fset_marker, set_marker_restricted, set_marker_both)
4500 (set_marker_restricted_both): Use it.
4501 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4502 Consistently rename charno to charpos.
4503 (marker_position): Add eassert.
4504 (marker_byte_position): Convert to eassert.
4506 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4508 Simplify list operations in unchain_overlay and unchain_marker.
4509 * buffer.c (unchain_overlay): Simplify. Add comment.
4510 * marker.c (unchain_marker): Simplify. Fix comments.
4512 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4514 Introduce fast path for the widely used marker operation.
4515 * alloc.c (build_marker): New function.
4516 * lisp.h (build_marker): New prototype.
4517 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
4518 * composite.c (autocmp_chars): Likewise.
4519 * editfns.c (buildmark): Remove.
4520 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
4521 (save_restriction_save): Use build_marker.
4522 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
4523 * window.c (save_window_save): Likewise.
4525 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

4528 to avoid redundant calls to unchain_overlay.
4529 * buffer.c (drop_overlay): New function.
4530 (delete_all_overlays, Fdelete_overlay): Use it.
4531 * minibuf.c (get_minibuffer): Fix comment.
4533 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4535 Port to OpenBSD 5.1 amd64.
4536 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4537 This is needed for OpenBSD, and should be harmless on all BSD systems.
4538 Also, include <sys/sysctl.h>, as it should be available on all
4539 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4540 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4541 use p_pid member, not kp_proc.pid.
4543 2012-07-06 Glenn Morris <rgm@gnu.org>
4545 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4547 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4549 More xmalloc and related cleanup.
4550 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

4557 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
4558 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4560 Omit needless casts involving void * pointers and allocation.
4561 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4562 as the former is more robust if P's type is changed.
4563 Prefer xzalloc to xmalloc + memset 0.
4564 Simplify malloc-or-realloc to realloc.
4565 Don't worry about xmalloc returning a null pointer.
4566 Prefer xstrdup to xmalloc + strcpy.
4567 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4569 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4570 alloca of a constant.
4572 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4574 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4575 hscroll is larger than the line width. Fixes long and futile
4576 looping inside extend_face_to_end_of_line (on a TTY) producing
4577 glyphs that are not needed and thrown away.
4579 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4581 * marker.c (set_marker_restricted_both): Simplify by using
4584 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4586 * editfns.c (region_limit): Simplify by using clip_to_bounds.
4588 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
4590 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
4591 not defined (Bug#11768).
4592 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
4593 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
4594 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
4595 followed by gtk_box_set_homogeneous (Bug#11768).
4596 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4597 (update_theme_scrollbar_width, xg_create_scroll_bar):
4598 Use gtk_scrollbar_new (Bug#11768).
4599 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
4600 (is_box_type): New function (Bug#11768).
4601 (xg_tool_item_stale_p): Call is_box_type.
4602 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
4603 with default display (Bug#11768).

4607 * xdisp.c (window_hscroll_limited): New function.
4608 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
4609 coordinates when window's hscroll is set to insanely large
4612 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
4614 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
4615 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
4617 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4620 * lisp.h (xzalloc): New prototype. Omit needless casts.
4621 * alloc.c (xzalloc): New function. Omit needless casts.

4675 * fileio.c (time_error_value): Check the right error number.
4676 Problem reported by Troels Nielsen in
4677 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
4679 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4681 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
4682 This should be fixed in a better way; see Eli Zaretskii in
4683 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
4684 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
4686 * fileio.c (time_error_value): Rename from special_mtime.
4687 The old name's problems were noted by Eli Zaretskii in
4688 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
4690 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
4691 This variable's comment says Emacs needs at least one GDB-visible
4692 symbol of type enum pvec_type, to work around GDB problems.
4693 The symbol's value doesn't matter.
4695 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
4696 that causes compilation to fail on pre-C99 compilers.
4698 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
4700 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
4701 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
4703 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4705 * buffer.c (init_buffer_once): Fix initialization of
4706 headers for buffer_defaults and buffer_local_symbols.
4707 Reported by Juanma Barranquero <lekktu@gmail.com>.
4709 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
4711 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
4712 * lisp.h (enum pvec_type): Use fewer bits.
4713 (PSEUDOVECTOR_SIZE_BITS): New constant.
4714 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
4715 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
4716 change in pvec_type.
4717 (PSEUDOVECTOR_TYPEP): New macro.
4718 (TYPED_PSEUDOVECTORP): Use it.
4719 * fns.c (internal_equal): Adapt code to extract pvectype.

4723 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
4724 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
4725 (sweep_vectors): Use it. Use local var `total_bytes' instead of
4726 abusing vector->header.next.nbytes.
4727 (live_vector_p): Use PVEC_TYPE.
4728 (mark_object): Adapt code to extract pvectype. Use switch.
4730 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4732 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
4733 Tighten new eassert a bit.
4735 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4737 Fix compilation with --enable-gcc-warnings and -O1
4739 * doprnt.c (doprnt): Change type of tem to int, initialize
4740 to avoid compiler warning. Add eassert.
4741 * search.c (simple_search): Initialize match_byte to avoid
4742 compiler warning. Add eassert.
4744 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4746 Avoid weird behavior with large horizontal scrolls.
4747 Without this change, for example, large hscroll values would
4748 mess up Emacs's display on Fedora 15 x86, presumably due to
4749 overflows in int calculations in the display code.
4750 Also, if buffers had long lines, Emacs would freeze.
4751 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
4752 (set_window_hscroll): New function, containing the old guts of
4753 Fset_window_hscroll. Return the clipped value.
4754 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
4755 This avoids the need to check against PTRDIFF_MAX.
4757 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
4759 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4761 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
4763 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4765 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
4766 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
4767 since GCC 4.4.6 issues a bogus warning for them.
4769 Fix bugs in file timestamp newness comparisons.
4770 * fileio.c (Ffile_newer_than_file_p):
4771 * lread.c (Fload): Use full timestamp resolution of files,
4772 not just the 1-second resolution, so that files that are only
4773 slightly newer still count as newer.
4774 * fileio.c (Ffile_newer_than_file_p): Don't assume file
4775 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
4777 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
4779 * fileio.c: Improve handling of file time marker. (Bug#11852)
4780 (special_mtime): New function.
4781 (Finsert_file_contents, Fverify_visited_file_modtime):
4782 Use it to set special mtime values consistently.
4784 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
4786 * fileio.c (Finsert_file_contents): Properly handle st_mtime
4787 marker for non-existing file. (Bug#11852)
4789 2012-07-03 Glenn Morris <rgm@gnu.org>
4791 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
4792 and did not make it into globals.h).
4794 2012-07-03 Tom Tromey <tromey@redhat.com>
4796 * window.c (Fset_window_margins, Fset_window_fringes)
4797 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
4798 * textprop.c (Fprevious_property_change): No longer static.
4799 * syntax.c (Fsyntax_table_p): No longer static.
4800 * process.c (Fget_process, Fprocess_datagram_address): No longer

4821 * intervals.h: Remove EXFUNs.
4822 * fontset.h: Remove EXFUN.

4827 * w32term.h: Remove EXFUNs.
4828 * window.h: Remove EXFUNs.
4829 * xsettings.h: Remove EXFUN.
4830 * xterm.h: Remove EXFUN.
4832 2012-07-03 Glenn Morris <rgm@gnu.org>
4834 * lisp.h (Frandom): Make it visible to C.
4835 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
4836 buffer for invisible buffers. (Bug#1229)
4838 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4840 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
4841 values which aren't power of 2.
4842 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
4843 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
4846 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
4848 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
4850 * alloc.c (mark_object): Revert part of last patch to use `switch'.
4852 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4854 * alloc.c (allocate_vector_block): Remove redundant
4855 calls to mallopt if DOUG_LEA_MALLOC is defined.
4856 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
4857 avoid calls to mallopt if zero_vector is returned.
4859 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4861 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
4862 is enabled, avoid dereferencing NULL current_sblock if
4865 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4867 Cleanup basic buffer management.
4868 * buffer.h (struct buffer): Change layout to use generic vector
4869 marking code. Fix some comments. Change type of 'clip_changed'
4870 to bitfield. Remove unused #ifndef old.
4871 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
4872 (GET_OVERLAYS_AT): Fix indentation.
4873 (for_each_per_buffer_object_at): New macro.
4874 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
4875 (Fbuffer_local_variables): Use it.
4876 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
4877 * alloc.c (allocate_buffer): Adjust to match new layout of
4878 struct buffer. Fix comment.
4879 (mark_overlay): New function.
4880 (mark_buffer): Use it. Use mark_vectorlike to mark normal
4881 Lisp area of struct buffer.
4882 (mark_object): Use it. Adjust marking of misc objects
4883 and related comments.
4885 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
4887 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
4888 wrapper that is not needed because the wrapped code is a no-op (zero
4889 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
4890 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
4892 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
4894 * alloc.c (mark_buffer): Simplify. Remove prototype.
4895 (mark_object): Add comment. Reorganize marking of vector-like
4896 objects. Use CHECK_LIVE for all vector-like objects except buffers
4897 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
4898 Avoid redundant calls to mark_vectorlike for bool vectors.
4900 2012-06-30 Glenn Morris <rgm@gnu.org>
4902 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
4904 * epaths.in (PATH_SITELOADSEARCH): New.
4905 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
4906 This is rather than relying on --enable-locallisppath elements
4907 having "site-lisp" in their names. (Bug#10208#25, 11658)
4909 2012-06-30 Eli Zaretskii <eliz@gnu.org>
4911 * w32proc.c (sys_select): Accept and ignore one more argument.
4913 * w32.c (emacs_gnutls_pull): Call select with one more argument.
4915 * sysselect.h [DOS_NT]: Don't include sys/select.h.
4916 (pselect) [!MS_DOS]: Redirect to sys_select.
4918 * sysdep.c: Don't include dos.h and dosfns.h.
4920 * process.c (sys_select):
4921 * msdos.c (sys_select): Accept one more argument and ignore it.
4923 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
4924 adapt data types and code to that.
4927 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
4928 which clashes with the gnulib function of the same name.
4930 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
4932 * font.c (font_style_to_value, font_style_symbolic)
4933 (font_prop_validate_style): Add type checks for values in
4936 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
4938 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
4941 2012-06-29 Eli Zaretskii <eliz@gnu.org>
4943 * xdisp.c (try_window_id): Undo last change.
4945 * w32.c (getwd): Adjust commentary about startup_dir.
4946 (init_environment): Always call sys_access, even in non-MSVC
4947 builds. Don't chdir to the directory of the Emacs executable.
4948 This undoes code from 1997 which was justified by the need to
4949 "avoid conflicts when removing and renaming directories". But its
4950 downside was that every relative file name was being interpreted
4951 relative to the directory of the Emacs executable, which can never
4952 be TRT. In particular, it broke sys_access when called with
4953 relative file names.
4954 (sys_access): Map GetLastError to errno.
4956 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4958 * window.h (struct window): Change type of 'fringes_outside_margins'

5148 Use sprintf return value instead of invoking strlen on result.
5149 In the old days this wasn't portable, since some sprintf
5150 implementations returned char *. But they died out years ago and
5151 Emacs already assumes sprintf returns int.
5152 Similarly for float_to_string.
5153 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

5161 Use sprintf or float_to_string result to avoid need to call strlen.
5162 * data.c (Fnumber_to_string):
5163 Use make_unibyte_string, since the string must be ASCII.
5164 * lisp.h, print.c (float_to_string): Now returns int length.
5165 * term.c (produce_glyphless_glyph):
5166 Use sprintf result rather than recomputing it.
5168 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
5169 * Makefile.in (ALL_CFLAGS):
5170 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

5199 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
5201 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

5204 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
5206 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
5207 instead of truncating it to 63 (admittedly a generous limit).

5267 * keyboard.c (kbd_buffer_get_event):
5268 * process.c (Faccept_process_output):
5269 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
5270 This improves on the previous patch, which introduced a bug
5271 when time_t is unsigned and as wide as intmax_t.
5272 See <http://bugs.gnu.org/9000#51>.
5274 2012-06-23 Eli Zaretskii <eliz@gnu.org>

5337 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5339 Support higher-resolution time stamps (Bug#9000).
5340 The time stamps are only nanosecond-resolution at the C level,
5341 since that's the best that any real-world system supports now.
5342 But they are picosecond-resolution at the Lisp level, as that's
5343 easy, and leaves room for future OS improvements.
5345 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5348 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5349 Don't get current time unless it's needed.
5351 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5352 now provides it if it's absent.
5353 (start_atimer): Port to higher-res time stamps.
5354 Check for time stamp overflow. Don't get current time more
5355 often than is needed.
5357 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5358 Include systime.h, not time.h.
5359 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
5361 * dired.c: Include stat-time.h.
5362 (Ffile-attributes): File times now have higher resolution.
5364 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
5365 (struct image): Timestamp now has higher resolution.
5367 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5368 has at least microseconds now. All uses removed.
5369 (update_frame, update_single_window, update_window, update_frame_1)
5370 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5371 (duration_to_sec_usec): Remove; no longer needed.
5373 * editfns.c (time_overflow): Now extern.
5374 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
5375 (float-time, Fformat_time_string, Fcurrent_time_string)
5376 (Fcurrent_time_zone): Accept and generate higher-resolution
5378 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
5379 (decode_time_components, lisp_seconds_argument): New functions.
5380 (make_time): Now static.
5381 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
5382 Report an error if the time is invalid, rather than having the caller
5385 * fileio.c: Include <stat-time.h>
5386 (Fcopy_file): Copy higher-resolution time stamps.
5387 Prefer to set the time stamp via a file descriptor if that works.
5388 (Fset_file_times, Finsert_file_contents, Fwrite_region)
5389 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
5390 (Fvisited_file_modtime, Fset_visited_file_modtime):
5391 Support higher-resolution time stamps.
5393 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
5395 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
5397 * image.c (prepare_image_for_display, clear_image_cache)
5398 (lookup_image): Port to higer-resolution time stamps.
5400 * keyboard.c (start_polling, bind_polling_period):
5401 Check for time stamp overflow.
5402 (read_char, kbd_buffer_get_event, timer_start_idle)
5403 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
5404 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5405 Port to higher-resolution time stamps. Do not assume time_t is signed.
5406 (decode_timer): New function. Timers are now vectors of length 9,
5407 not 8, to accommodate the picosecond component.
5408 (timer_check_2): Use it.
5410 * nsterm.m (select_timeout, timeval_subtract): Remove.
5411 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5412 as they're a bit more accurate and handle overflow better.
5413 (ns_select): Change prototype to be compatible with pselect.
5414 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5415 * nsterm.h (ns_select): Adjust prototype.
5417 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5418 us-resolution time stamps.
5419 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5421 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5423 * lisp.h (time_overflow): New decl.
5424 (wait_reading_process_output): First arg is now intmax_t, not int,
5425 to accommodate larger waits.
5427 * process.h (struct Lisp_Process.read_output_delay):
5428 Now counts nanoseconds, not microseconds.
5429 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
5431 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
5432 (wait_reading_process_output):
5433 Port to ns-resolution time stamps.
5434 (Faccept_process_output, wait_reading_process_output):
5435 Check for time stamp overflow. Do not assume time_t is signed.
5436 (select_wrapper): Remove; we now use pselect.
5437 (Fprocess_attributes): Now generates ns-resolution time stamps.
5439 * sysdep.c: Include utimens.h. Don't include utime.h
5440 or worry about struct utimbuf; gnulib does that for us now.
5441 (gettimeofday): Remove; gnulib provides a substitute.
5442 (make_timeval): New function.
5443 (set_file_times): Now sets ns-resolution time stamps.
5444 New arg FD; all uses changed.
5445 (time_from_jiffies, ltime_from_jiffies, get_up_time)
5446 (system_process_attributes):
5447 Now returns ns-resolution time stamp. All uses changed.
5448 Check for time stamp overflow.
5450 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5451 provides a substitute now.
5453 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5454 since it guarantees struct timespec.
5455 (EMACS_TIME): Now struct timespec, so that we can support
5456 ns-resolution time stamps.
5457 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5458 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5459 (EMACS_USECS): Remove.
5460 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5461 so multiply the arg by 1000 before storing it.

5464 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

5471 (make_timeval, make_lisp_time, decode_time_components): New decls.
5472 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
5473 that it mishandled time_t overflow. You can't compare by subtracting!
5474 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
5475 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

5503 (timeval_subtract): Remove; no longer needed.
5504 (XTflash, XTring_bell, x_wait_for_event):
5505 Port to ns-resolution time stamps. Don't assume time_t is signed.

5511 2012-06-22 Eli Zaretskii <eliz@gnu.org>
5513 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
5514 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5515 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
5516 staticidx goes up to 1597 out of 1600 = 0x640.)

5520 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
5521 Otherwise, the umask might be mistakenly 0 while handling input signals.

5554 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
5555 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
5556 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
5557 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

5566 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
5567 gets killed during executing of this function (Bug#11665).
5568 Try to always return Qt when the buffer has been actually killed.
5569 (Vkill_buffer_query_functions): In doc-string say that functions
5570 run by this hook should not change the current buffer.
5572 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
5574 Fix recently-introduced process.c problems found by static checking.

5595 This removes the need for CHECK.
5596 (CHECK): Remove. Its comments about always evaluating its
5597 argument were confusing, as 'eassert' typically does not evaluate
5600 * coding.c (produce_chars): Use ptrdiff_t, not int.
5602 * xterm.c (x_draw_underwave): Check for integer overflow.
5603 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

5921 (all_vectors): Rename to `large_vectors'.
5922 (allocate_vector_from_block, init_vectors, allocate_vector_from_block)
5923 (sweep_vectors): New functions.
5924 (allocate_vectorlike): Return `zero_vector' as the only vector of
5925 0 items. Allocate new vector from block if vector size is less than
5926 or equal to VBLOCK_BYTES_MAX.
5927 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
5928 (init_alloc_once): Add call to init_vectors.
5930 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
5932 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
5934 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
5936 * doprnt.c (doprnt): Truncate multibyte char correctly.
5937 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
5938 would mishandle a string argument "Xc" if X was a multibyte
5939 character of length 2: it would truncate after X's first byte
5940 rather than including all of X.
5942 2012-06-06 Chong Yidong <cyd@gnu.org>
5944 * buffer.c (word_wrap): Doc fix.
5946 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>
5948 * xdisp.c (note_mode_line_or_margin_highlight): Pacify gcc -Wall.

5964 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
5967 2012-06-03 Chong Yidong <cyd@gnu.org>
5969 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
5970 (note_mode_line_or_margin_highlight): If there is no help echo,
5971 use mode-line-default-help-echo. Handle the case where the mouse
5972 position is past the end of the mode line string.
5974 * buffer.c (buffer_local_value_1): New function, split from
5975 Fbuffer_local_value; can return Qunbound.
5976 (Fbuffer_local_value): Use it.
5977 (Vmode_line_format): Docstring tweaks.
5979 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5981 * sysdep.c (system_process_attributes): Improve comment.
5983 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
5985 * keyboard.c: Export real-this-command to Elisp.
5986 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
5987 and DEFVAR it. Update all users.
5989 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5991 * minibuf.c (Fassoc_string): Remove duplicate declaration.
5993 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
5994 Convert pctcpu and pctmem to Lisp float properly.
5995 Let the compiler fold better, as 100.0/0x8000 is exact.
5997 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
5999 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
6002 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
6004 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
6006 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
6008 For a 'struct window', replace some Lisp_Object fields to
6009 bitfields where appropriate, remove unused fields.
6010 * window.h (struct window): Remove unused 'last_mark_x' and
6011 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
6012 change it's type from Lisp_Object to bitfield.
6013 Change type of 'force_start', 'optional_new_start',
6014 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
6015 fields from Lisp_Object to bitfield. Adjust users accordingly.
6017 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6019 Pacify gcc -Wdouble-precision when using Xaw.
6020 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
6021 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
6022 Use 'float' consistently, rather than 'float' in most places
6023 and 'double' in a couple of places.
6025 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6027 * xdisp.c (handle_stop): Detect whether we have overlay strings
6028 loaded by testing it->current.overlay_string_index to be
6029 non-negative, instead of checking whether n_overlay_strings is
6030 positive. (Bug#11587)
6032 2012-05-31 Chong Yidong <cyd@gnu.org>
6034 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
6036 * doc.c (Fsubstitute_command_keys): Doc fix.
6038 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6040 * search.c (search_buffer): Remove calls to
6041 r_alloc_inhibit_buffer_relocation, as it is now called by
6042 maybe_unify_char, which was the cause of relocation of buffer text
6045 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6047 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6048 for the duration of call to load_charset, to avoid problems with
6049 callers of maybe_unify_char that access buffer text through C
6052 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6053 decrement the inhibition flag, instead of just setting or
6056 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6058 Remove obsolete '#define static' cruft.
6059 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6060 This #undef was "temporary" in 2000; it is no longer needed
6061 now that '#define static' has gone away.
6062 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6063 (gray_bitmap_bits): Remove; no longer needed.
6064 All uses replaced with definiens.
6065 * xterm.c: Include "bitmaps/gray.xbm".
6067 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6069 Clean up __executable_start, monstartup when --enable-profiling.
6070 The following changes affect the code only when profiling.
6071 * dispnew.c (__executable_start): Rename from safe_bcopy.
6072 Define only on platforms that need it.
6073 * emacs.c: Include <sys/gmon.h> when profiling.
6074 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6075 (__executable_start): Remove decl, since lisp.h does it now.
6076 (safe_bcopy): Remove decl; no longer has that name.
6077 (main): Coalesce #if into single bit of code, for simplicity.
6078 Cast pointers to uintptr_t, since standard libraries want integers
6080 * lisp.h (__executable_start): New decl.
6082 2012-05-31 Glenn Morris <rgm@gnu.org>
6084 * image.c (Fimagemagick_types): Doc fix.
6086 2012-05-30 Jim Meyering <meyering@redhat.com>
6088 * callproc.c (Fcall_process_region): Include directory component
6089 in mkstemp error message (Bug#11586).

6093 * alloc.c, lisp.h (make_pure_vector): Now static.
6095 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

6098 Move to byte-run.el.
6099 (Fautoload): Do the hash-doc more carefully.
6100 * data.c (Fdefalias): Purify definition, except for keymaps.
6101 (Qdefun): Move from eval.c.
6102 * lisp.h (Qdefun): Remove.
6103 * lread.c (read1): Tiny simplification.
6105 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
6107 Do not create empty overlays with the evaporate property (Bug#9642).
6108 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6109 Bug#9642, but explicitly check that the buffer the overlay would
6110 be moved to is live and rearrange lines to make sure that errors
6111 will not put the overlay in an inconsistent state.
6112 (Fdelete_overlay): Cosmetics.
6114 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6116 * w32term.c (my_bring_window_to_top): New function.
6117 (x_raise_frame): Use handle returned by DeferWindowPos, which
6118 could be different from the original one.
6119 Call my_bring_window_to_top instead of my_set_foreground_window.
6122 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6123 by calling BringWindowToTop.
6125 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6126 (WM_EMACS_END): Increase by one.
6128 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6130 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6131 This avoids undefined behavior that might cause the eassert
6132 to not catch an out-of-range value.
6134 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6136 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
6137 Update dependencies.
6139 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6141 * bidi.c (bidi_mirror_char): Fix last change.
6143 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
6145 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
6146 when referring to sectname field in printf format.
6148 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
6150 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6151 Only r_alloc_inhibit_buffer_relocation needed to be added;
6152 the others were already declared.
6154 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6155 before checking whether it's out of range. Put the check inside
6157 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6159 2012-05-27 Ken Brown <kbrown@cornell.edu>
6161 * callproc.c (Fcall_process): Restore a line that was accidentally
6162 commented out in the 2011-02-13 change (bug#11547).
6164 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6166 * lisp.h [REL_ALLOC]: Add prototypes for external functions
6167 defined on ralloc.c.
6169 * buffer.c [REL_ALLOC]: Remove prototypes of
6170 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
6171 they are now on lisp.h.
6173 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6175 * search.c (search_buffer): Use it to inhibit relocation of buffer
6176 text while re_search_2 is doing its job, because re_search_2 is
6177 passed C pointers to buffer text. (Bug#11519)
6179 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6182 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6183 state after an additional call to move_it_in_display_line_to, keep
6184 the values of it->max_ascent and it->max_descent found for the
6186 (pos_visible_p): Revert the comparison against bottom_y to what it
6187 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
6190 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6192 Fix coding-related core dumps with gcc -ftrapv.
6193 The code was computing A - B, where A and B are pointers, and B is
6194 random garbage. This can lead to core dumps on platforms that
6195 have special pointer registers, and it also leads to core dumps on
6196 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6197 A - B only when B is initialized properly.
6198 * coding.c (coding_set_source, coding_set_destination): Return void.
6199 (coding_change_source, coding_change_destinations): New functions,
6200 with the old behaviors of coding_set_source and coding_set_destination.
6201 All callers that need an offset changed to use these new functions.
6203 2012-05-26 Glenn Morris <rgm@gnu.org>
6205 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
6207 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6209 Extend mouse support on W32 text-mode console.
6210 * xdisp.c (draw_row_with_mouse_face):
6211 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6213 * w32console.c: Include window.h.
6214 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6216 (initialize_w32_display): Initialize mouse-highlight data.
6218 * w32inevt.c: Include termchar.h and window.h.
6219 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6220 moves, call note_mouse_highlight. If help_echo changed, call
6221 gen_help_event to produce help-echo message in the echo area.
6222 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6225 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6227 * lread.c (read1): Simplify slightly to avoid an overflow warning
6228 with GCC 4.7.0 on x86-64.
6230 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6232 * bidi.c (bidi_mirror_char): Revert last change: an int is
6233 definitely wide enough here.
6235 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
6237 Fix integer width and related bugs (Bug#9874).
6238 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
6239 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
6240 (string_bytes, check_sblock, allocate_string_data):
6241 (compact_small_strings, Fmake_bool_vector, make_string)
6242 (make_unibyte_string, make_multibyte_string)
6243 (make_string_from_bytes, make_specified_string)
6244 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
6245 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
6247 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6248 (allocate_pseudovector):
6249 Use int, not EMACS_INT, where int is wide enough.
6250 (inhibit_garbage_collection, Fgarbage_collect):
6251 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6252 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
6253 int might not be wide enough.
6254 (bidi_cache_search, bidi_cache_find, bidi_init_it)
6255 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6256 (bidi_at_paragraph_end, bidi_find_paragraph_start)
6257 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
6258 (bidi_level_of_next_char, bidi_move_to_visually_next):
6259 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6260 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
6261 (Fkill_buffer, Fset_buffer_major_mode)
6262 (advance_to_char_boundary, Fbuffer_swap_text)
6263 (Fset_buffer_multibyte, overlays_at, overlays_in)
6264 (overlay_touches_p, struct sortvec, record_overlay_string)
6265 (overlay_strings, recenter_overlay_lists)
6266 (adjust_overlays_for_insert, adjust_overlays_for_delete)
6267 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
6268 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
6269 (Foverlay_recenter, last_overlay_modification_hooks_used)
6270 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6271 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6272 (validate_region): Omit unnecessary test for b <= e,
6273 since that's guaranteed by the previous test.
6274 (adjust_overlays_for_delete): Avoid pos + length overflow.
6275 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6276 (report_overlay_modification):
6277 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6278 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
6279 Omit pointer cast, which isn't needed anyway, and doesn't work
6280 after the EMACS_INT -> ptrdiff_t change.
6281 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
6282 * buffer.h: Adjust decls to match defn changes elsewhere.
6283 (struct buffer_text, struct buffer):
6284 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6285 Use EMACS_INT, not int, where int might not be wide enough.
6286 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
6287 not int, to avoid needless 32-bit limit on 64-bit hosts.
6288 (exec_byte_code): Use tighter memory-full test, one that checks
6289 for alloca overflow. Don't compute the address of the object just
6290 before an array, as that's not portable. Use EMACS_INT, not
6291 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
6292 * callint.c (Fcall_interactively):
6293 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6294 * callproc.c (call_process_kill, Fcall_process):
6295 Don't assume pid_t fits into an Emacs fixnum.
6296 (call_process_cleanup, Fcall_process, child_setup):
6297 Don't assume pid_t fits into int.
6298 (call_process_cleanup, Fcall_process, delete_temp_file)
6299 (Fcall_process_region):
6300 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6301 (Fcall_process): Simplify handling of volatile integers.
6302 Use int, not EMACS_INT, where int will do.
6303 * casefiddle.c (casify_object, casify_region, operate_on_word)
6304 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
6305 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6306 (casify_object): Avoid integer overflow when overallocating buffer.
6307 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
6308 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
6309 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
6310 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6311 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6312 integers are now checked earlier. All uses replaced with XINT.
6314 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6315 For CCL_MapSingle, check that content and value are in int range.
6316 (ccl_driver, Fregister_code_conversion_map):
6317 Check that Vcode_version_map_vector is a vector.
6318 (resolve_symbol_ccl_program): Check that vector header is in range.
6319 Always copy the vector, so that we can check its contents reliably
6320 now rather than having to recheck each instruction as it's being
6321 executed. Check that vector words fit in 'int'.
6322 (ccl_get_compiled_code, Fregister_ccl_program)
6323 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6324 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
6325 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
6326 contents are in range.
6327 (Fccl_execute_on_string): Check that status is in range.
6328 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
6329 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
6330 Accept and return EMACS_INT, not int, because callers can pass values
6332 (c_string_width, strwidth, lisp_string_width, chars_in_text)
6333 (multibyte_chars_in_text, parse_str_as_multibyte)
6334 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
6335 (str_as_unibyte, str_to_unibyte, string_count_byte8)
6336 (string_escape_byte8, Fget_byte):
6337 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6338 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
6339 avoid mishandling large integers.
6340 * character.h: Adjust decls to match defn changes elsewhere.
6341 * charset.c (load_charset_map_from_file, find_charsets_in_text)
6342 (Ffind_charset_region):
6343 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6344 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
6345 (load_charset_map_from_vector, Fdefine_charset_internal):
6346 Don't assume fixnum fits in int.
6347 (load_charset_map_from_vector, Fmap_charset_chars):
6348 Remove now-unnecessary CHECK_NATNUMs.
6349 (Fdefine_charset_internal): Check ranges here, more carefully.
6350 Don't rely on undefined behavior with signed left shift overflow.
6351 Don't assume unsigned int fits into fixnum, or that fixnum fits
6352 into unsigned int. Don't require max_code to be a valid fixnum;
6353 that's not true for gb10830 4-byte on a 32-bit host. Allow
6354 invalid_code to be a cons, for the same reason. Require code_offset
6355 to be a character. Avoid int overflow if max_char is close
6357 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
6358 this is intended anyway and avoids some undefined behavior.
6359 (load_charset_map): Pass unsigned, not int, as 2nd arg of
6360 INDEX_TO_CODE_POINT, as that's what it expects.

7071 * lisp.h (USE_LSB_TAG):
7072 * mem-limits.h (EXCEEDS_LISP_PTR):
7073 Use VAL_MAX, not VALBITS, in #if.
7074 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
7075 (EMACS_UINT): Define unconditionally now.
7076 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
7077 (BITS_PER_EMACS_INT): New constants, replacing
7078 what used to be in config.h, but not useful in #if.
7079 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
7080 define them any more.
7081 (VAL_MAX): New macro.
7083 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
7084 BITS_PER_EMACS_INT, in #if.
7085 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
7086 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
7087 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
7088 * s/ms-w32.h (DATA_START):
7089 Move here from removed file m/intel386.h.
7090 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
7091 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
7093 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
7095 Assume C89 or later.
7096 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
7097 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
7099 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
7100 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
7101 * textprop.c, tparam.c (NULL): Remove.
7102 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
7103 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
7104 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
7105 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
7106 * xterm.c (input_signal_count): Assume volatile works.
7108 2012-05-21 Ken Brown <kbrown@cornell.edu>
7110 * xgselect.c (xg_select): Fix first argument in call to 'select'
7113 2012-05-20 Ken Brown <kbrown@cornell.edu>
7115 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
7116 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
7118 2012-05-19 Ken Brown <kbrown@cornell.edu>
7120 * xfns.c (x_in_use): Remove `static' qualifier.
7121 * xterm.h (x_in_use): Declare.
7122 * xgselect.c: Include xterm.h.
7123 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
7124 and `display_arg' (bug#9754).
7126 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
7128 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
7130 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
7131 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
7133 2012-05-18 Eli Zaretskii <eliz@gnu.org>
7135 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
7137 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
7138 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
7140 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
7141 reference to image_cache->refcount.
7142 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
7144 2012-05-17 Juri Linkov <juri@jurta.org>
7146 * search.c (Fword_search_regexp, Fword_search_backward)
7147 (Fword_search_forward, Fword_search_backward_lax)
7148 (Fword_search_forward_lax): Move functions to isearch.el
7149 (bug#10145, bug#11381).
7151 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
7153 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
7155 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
7157 * lread.c (init_obarray): Declare Qt and Qnil as special.
7159 2012-05-14 Glenn Morris <rgm@gnu.org>
7161 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
7162 Put "libexec" before "bin", for the sake of init_callproc_1.
7164 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7166 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
7168 * unexaix.c: Port to more-recent AIX compilers.
7169 (report_error, report_error_1, make_hdr, copy_sym)
7170 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
7171 Make arguments const char *, not char *, to avoid violations of C
7172 standard and to fix some AIX warnings reported by Gilles Pion.
7174 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7176 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
7177 already have overlays loaded.
7178 (handle_single_display_spec): Before returning without displaying
7179 fringe bitmap, synchronize the bidi iterator with the main display
7180 iterator, by calling iterate_out_of_display_property.
7181 (iterate_out_of_display_property): Detect buffer iteration by
7182 testing that it->string is a Lisp string.
7183 (get_next_display_element): When the current object is exhausted,
7184 and there's something on it->stack, call set_iterator_to_next to
7185 proceed with what's on the stack, instead of returning zero.
7186 (set_iterator_to_next): If called at the end of a Lisp string,
7187 proceed to consider_string_end without incrementing string
7188 position. Don't increment display vector index past the end of
7189 the display vector. (Bug#11417)
7190 (pos_visible_p): Don't report a position visible when move_it_to
7191 stopped at the last line of window, which happens to be scanned
7192 backwards by the bidi iteration. (Bug#11464)
7194 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7196 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7197 and right-margin display specs even if the spec is invalid or we
7198 are on a TTY, and thus unable to display on the fringes.
7199 That's because the text with the property will not be displayed anyway,
7200 so we need to signal to the caller that this is a "replacing"
7201 display spec. This fixes display when the spec is invalid or we
7204 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7206 * unexaix.c (make_hdr): Fix typo in prototype.
7207 This bug broke the build on AIX. Problem reported by Gilles Pion.
7209 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
7211 * keyboard.c (kbd_buffer_get_event): Read special events also in
7212 batch mode. (Bug#11415)
7214 2012-05-12 Glenn Morris <rgm@gnu.org>
7216 * ns.mk: Update for ns_appbindir no longer having trailing "/".
7218 2012-05-12 Eli Zaretskii <eliz@gnu.org>
7220 * lisp.mk (lisp): Add newcomment.elc.
7222 2012-05-12 Glenn Morris <rgm@gnu.org>
7224 * Makefile.in (MKDIR_P): New, set by configure.
7225 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
7227 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
7229 Remove unused function hourglass_started.
7230 * dispextern.h (hourglass_started):
7231 * w32fns.c (hourglass_started):
7232 * xdisp.c (hourglass_started): Remove.
7234 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7236 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7237 Update dependencies.
7239 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7241 * xgselect.c (xg_select): Put maxfds+1 into a var.
7242 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
7244 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7246 2012-05-10 Dave Abrahams <dave@boostpro.com>
7248 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7249 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7251 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7253 * dbusbind.c (xd_registered_buses): New internal Lisp object.
7254 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7255 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7256 Initialize xd_registered_buses.
7258 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7260 Untag more efficiently if USE_LSB_TAG.
7261 This is based on a proposal by YAMAMOTO Mitsuharu in
7262 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7263 For an admittedly artificial (nth 8000 longlist) benchmark on
7264 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7265 Emacs's overall text size by 1%.
7266 * lisp.h (XUNTAG): New macro.
7267 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7268 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7269 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7270 * eval.c (Fautoload):
7271 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7272 * frame.h (XFRAME): Use XUNTAG.
7274 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7275 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7276 Remove unportable assumptions about print widths of types like
7278 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7279 intptr_t when converting between pointer and integer, to avoid GCC
7280 warnings about wrong width.
7282 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7284 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7285 stack for each reader_thread, instead of defaulting to 8MB
7286 determined by the linker. This avoids failures in creating
7287 subprocesses on Windows 7, see the discussion in this thread:
7288 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7290 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7292 Fix up display of the *Minibuf-0* buffer in the mini window.
7293 * keyboard.c (read_char): Don't clear the echo area if there's no
7295 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7296 contents of *Minibuf-0*) if there's no message displayed in its stead.
7298 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7300 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7303 2012-05-06 Chong Yidong <cyd@gnu.org>
7305 * lisp.mk (lisp): Update.
7307 2012-05-05 Jim Meyering <meyering@redhat.com>
7309 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7311 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7313 * data.c (PUT_ERROR): New macro.
7314 (syms_of_data): Use it. Add new error type `user-error'.
7315 * undo.c (user_error): New function.
7316 (Fprimitive_undo): Use it.
7317 * print.c (print_error_message): Adjust print style for `user-error'.
7318 * keyboard.c (user_error): New function.
7319 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7321 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7323 Do not limit current-time-string to years 1000..9999.
7324 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7325 (Fcurrent_time_string): Support any year that is supported by the
7326 underlying localtime representation. Don't use asctime, as it
7327 has undefined behavior for years outside the range -999..9999.
7329 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7331 Fix race conditions involving setenv, gmtime, localtime, asctime.
7332 Without this fix, interrupts could mess up code that uses these
7333 nonreentrant functions, since setting TZ invalidates existing
7334 tm_zone or tzname values, and since most of these functions return
7335 pointers to static storage.
7336 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7337 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7338 Grow the critical sections to include not just invoking
7339 localtime/gmtime, but also accessing these functions' results
7340 including their tm_zone values if any, and any related TZ setting.
7341 (format_time_string): Last arg is now struct tm *, not struct tm **,
7342 so that the struct tm is saved in the critical section.
7343 All callers changed. Simplify allocation of initial buffer, partly
7344 motivated by the fact that memory allocation needs to be outside
7345 the critical section.
7347 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7349 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7350 with RESET_INTERVAL.
7352 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7353 Remove duplicated buffer name initialization.
7355 2012-05-02 Jim Meyering <jim@meyering.net>
7357 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7359 * xfns.c (x_window): Use xstrdup (Bug#11375).
7361 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7363 * xdisp.c (pos_visible_p): If already at a newline from the
7364 display string before the 'while' loop, don't walk back the glyphs
7365 from it3.glyph_row. Solves assertion violation when the display
7366 string begins with a newline (egg.el). (Bug#11367)
7368 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7370 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7373 2012-05-01 Glenn Morris <rgm@gnu.org>
7375 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7376 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7377 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7378 All were removed before 23.1.
7380 * dispnew.c: Remove HAVE_LIBNCURSES test;
7381 it is always true on relevant platforms.
7383 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7384 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7386 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
7388 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
7390 * .gdbinit (xpr): Remove checks for no longer existing misc types.
7391 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
7394 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
7396 Do not avoid creating empty evaporating overlays (Bug#9642).
7397 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7398 That is, do not delete an evaporating overlay if it becomes
7399 empty after its bounds are adjusted to fit within its buffer.
7400 This fix caused other problems, and I'm reverting it until we get
7401 to the bottom of them.
7403 2012-04-27 Chong Yidong <cyd@gnu.org>
7405 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7407 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7409 * xdisp.c (pos_visible_p): If the window start position is beyond
7410 ZV, start the display from buffer beginning. Prevents assertion
7411 violation in init_iterator when the minibuffer window is scrolled
7414 * window.c (window_scroll_pixel_based): Likewise.
7416 2012-04-27 Chong Yidong <cyd@gnu.org>
7418 * keymap.c (where_is_internal): Doc fix (Bug#10872).
7420 2012-04-27 Glenn Morris <rgm@gnu.org>
7422 * fileio.c (Fcopy_file, Fset_file_selinux_context):
7423 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
7425 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7427 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
7428 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
7430 2012-04-26 Eli Zaretskii <eliz@gnu.org>
7432 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7433 display element, check also the underlying string or buffer
7434 character. (Bug#11341)
7436 * w32menu.c: Include w32heap.h.
7437 (add_menu_item): If the call to AppendMenuW (via
7438 unicode_append_menu) fails, disable Unicode menus only if we are
7439 running on Windows 9X/Me.
7441 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7443 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
7444 (xgetint): Add missing shift for LSB tags.
7446 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7448 * keyboard.c (read_char): Don't wipe echo area for select window
7449 events: These might get delayed via `mouse-autoselect-window'
7452 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
7454 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
7455 manipulation of :loaded-from data.
7457 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
7459 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
7460 now a cons (bug#11311).
7462 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7464 Do not create empty overlays with the evaporate property (Bug#9642).
7465 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7466 if it becomes empty after its bounds are adjusted to fit within
7467 its buffer. Without this fix, in a nonempty buffer (let ((o
7468 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7469 yields an empty overlay that has the evaporate property, which is
7470 not supposed to happen.
7472 Fix minor GTK3 problems found by static checking.
7473 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7474 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7475 (struct _EmacsFixedClass, emacs_fixed_get_type):
7476 Move decls here from emacsgtkfixed.h, since they needn't be public.
7477 (emacs_fixed_get_type): Now static.
7478 (emacs_fixed_class_init): Omit unused local.
7479 (emacs_fixed_child_type): Remove; unused.

7481 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7482 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
7483 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
7484 (EMACS_FIXED_GET_CLASS): Remove; unused.
7485 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
7487 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
7488 Problem reported by Juanma Barranquero for Windows -Wunused-function.
7490 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7492 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
7493 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
7494 (__malloc_size_t, __malloc_ptrdiff_t):
7495 Remove. All uses removed, replaced by the definiens if needed,
7496 since we can assume C89 or better now.
7497 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
7498 (protect_malloc_state, align, get_contiguous_space)
7499 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
7500 (malloc_atfork_handler_child, malloc_enable_thread)

7503 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
7504 (special_realloc, _realloc_internal_nolock, _realloc_internal)
7505 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
7506 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
7507 Define using prototypes, not old style.
7508 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
7509 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
7510 (align): Don't assume that signed integer overflow wraps around.
7511 Omit unused local var.
7512 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
7513 (_free_internal_nolock, memalign, mallochook, reallochook):
7514 Omit no-longer-needed casts.
7515 (valloc): Use getpagesize, not __getpagesize.
7516 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
7517 (struct hdr): The 'magic' member is now size_t, not unsigned long.
7519 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.

7574 since the two debugging options are incompatible.
7575 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7577 (mem_init, mem_insert, mem_insert_fixup):
7578 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

7744 2012-04-11 Daniel Colascione <dancol@dancol.org>
7746 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
7747 against is gone. It's better to use vfork now so that when Cygwin
7748 gains a new, working vfork, we use it automatically (bug#10398).

7805 2012-04-09 Eli Zaretskii <eliz@gnu.org>
7807 * xdisp.c (set_cursor_from_row): If the display string appears in
7808 the buffer at position that is closer to point than the position
7809 after the display string, display the cursor on the first glyph of
7810 the display string. Fixes cursor display when a 'display' text
7811 property immediately follows invisible text. (Bug#11094)
7813 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
7815 composite.c: use 'double' consistently
7816 * composite.c (get_composition_id): Use 'double' consistently
7817 instead of converting 'float' to 'double' and vice versa; this is

7867 [!WINDOWSNT]: New macros.
7868 (init_libxml2_functions, libxml2_loaded_p): New functions.
7869 (parse_region): Call fn_xmlCheckVersion instead of using the macro
7870 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
7871 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.

7892 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
7893 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
7894 about subtle differences between FETCH_CHAR* and STRING_CHAR*
7895 macros related to unification of CJK characters. For the details,
7896 see the discussion following the message here:
7897 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

7916 position we get to after a call to move_it_to fails the
7917 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
7918 only if we wind up in a string from display property. (Bug#11063)
7920 * window.c (Fdelete_other_windows_internal): Invalidate the row
7921 and column information about mouse highlight, so that redisplay
7922 restores it after reallocating the glyph matrices. (Bug#7464)
7924 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
7925 string comes from a `display' text property, use the buffer
7926 position of that property as if we actually saw that position in
7928 (move_it_by_lines): Remove the assertion that
7929 "it->current_x == 0 && it->hpos == 0" which can be legitimately
7930 violated when there's a before-string at the beginning of a line.
7933 2012-03-30 Eli Zaretskii <eliz@gnu.org>

7990 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
7991 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
7992 when fetching a multibyte character consumes more bytes than
7993 CHAR_BYTES returns, due to unification of CJK characters in
7994 string_char. (Bug#11073)
7996 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
7998 * process.c (wait_reading_process_output): Handle pty disconnect
7999 by refraining from sending oneself a SIGCHLD (bug#10933).
8001 2012-03-22 Chong Yidong <cyd@gnu.org>

8016 * w32proc.c (Fw32_set_console_codepage)
8017 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
8020 2012-03-20 Chong Yidong <cyd@gnu.org>
8022 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
8023 to reflect default non-nil value of redisplay-dont-pause.
8025 2012-03-19 Kenichi Handa <handa@m17n.org>
8027 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
8028 it fit in a valid range (Bug#11003).
8030 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8032 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8033 that is not from display property, accept the row as a "cursor
8034 row" if one of the string's character has a non-nil `cursor'
8035 property. Fixes cursor positioning when there are newlines in
8036 overlay strings, e.g. in icomplete.el. (Bug#11035)
8038 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
8040 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
8042 2012-03-12 Chong Yidong <cyd@gnu.org>
8044 * eval.c (inhibit_lisp_code): Rename from
8045 inhibit_window_configuration_change_hook; move from window.c.
8047 * xfns.c (unwind_create_frame_1, Fx_create_frame):
8048 * window.c (run_window_configuration_change_hook)
8049 (syms_of_window): Callers changed.

8064 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
8066 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>

8069 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8072 2012-03-03 Glenn Morris <rgm@gnu.org>
8074 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
8076 2012-03-02 Eli Zaretskii <eliz@gnu.org>
8078 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
8079 position past the first glyph_row that ends at ZV. (Bug#10902)
8080 (redisplay_window, next_element_from_string): Fix typos in
8082 (redisplay_window): Pass to move_it_vertically the margin in
8083 pixels, not in screen lines.
8085 2012-03-02 Glenn Morris <rgm@gnu.org>
8087 * buffer.c (buffer-list-update-hook): Doc fix.
8089 2012-02-29 Eli Zaretskii <eliz@gnu.org>

8092 push_it before setting up the iterator for the first overlay
8093 string, even if we have an empty string loaded.
8094 (next_overlay_string): If there's an empty string on the iterator
8095 stack, pop the stack. (Bug#10903)
8097 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8099 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8100 Suggested by Stefan Monnier in
8101 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8102 * alloc.c (widen_to_Lisp_Object): New static function.
8103 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8104 and widening them to Lisp_Objects. This would work even if
8105 USE_LSB_TAG is defined and wide integers are used, which might
8106 happen in a future version of Emacs.
8108 2012-02-25 Chong Yidong <cyd@gnu.org>
8110 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
8113 * xselect.c (Fx_selection_exists_p): Doc fix.
8114 (x_clipboard_manager_save_all): Print an informative message
8115 before saving to clipboard manager.
8117 2012-02-24 Chong Yidong <cyd@gnu.org>
8119 * keyboard.c (process_special_events): Handle all X selection
8120 requests in kbd_buffer, not just the next one (Bug#8869).
8122 2012-02-23 Chong Yidong <cyd@gnu.org>
8124 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
8125 call when setting menu-bar-lines and tool-bar-lines parameters.
8126 (unwind_create_frame_1): New helper function.
8128 * window.c (inhibit_window_configuration_change_hook): New var.
8129 (run_window_configuration_change_hook): Obey it.
8130 (syms_of_window): Initialize it.
8132 2012-02-22 Chong Yidong <cyd@gnu.org>
8134 * xterm.c (x_draw_image_relief): Add missing type check for
8135 Vtool_bar_button_margin (Bug#10743).
8137 2012-02-21 Chong Yidong <cyd@gnu.org>
8139 * fileio.c (Vfile_name_handler_alist): Doc fix.
8141 * buffer.c (Fget_file_buffer): Protect against invalid file
8142 handler return value.
8144 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
8146 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
8147 when computing $valmask.
8149 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8150 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8151 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8152 It's useless in that case, and it can cause problems on hosts
8153 that allocate halves of EMACS_INT values separately.
8154 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8155 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8156 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8157 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8158 it avoids undefined behavior on hosts where shifting right by more
8159 than the word width has undefined behavior.
8161 2012-02-19 Chong Yidong <cyd@gnu.org>
8163 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
8164 (Funhandled_file_name_directory, Ffile_name_as_directory)
8165 (Fdirectory_file_name, Fexpand_file_name)

8183 2012-02-15 Chong Yidong <cyd@gnu.org>
8185 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
8186 marked as special. Also, starting docstrings with * is obsolete.
8188 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
8190 * gnutls.c (emacs_gnutls_write): Fix last change.
8192 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

8201 2012-02-12 Chong Yidong <cyd@gnu.org>
8203 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
8204 as that creates a dangerous corner case.
8206 * window.c (Fdelete_window_internal): Invalidate the mouse
8207 highlight (Bug#9904).
8209 2012-02-12 Glenn Morris <rgm@gnu.org>

8214 * nsselect.m (Fx_own_selection_internal)
8215 (Fx_disown_selection_internal, Fx_selection_exists_p)
8216 (Fx_selection_owner_p, Fx_get_selection_internal):
8217 Sync docs and argument specs with the xselect.c versions.

8235 2012-02-09 Kenichi Handa <handa@m17n.org>
8237 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
8239 2012-02-07 Chong Yidong <cyd@gnu.org>
8241 * buffer.c (Fbuffer_local_variables)
8242 (buffer_lisp_local_variables): Handle unbound vars correctly;
8243 don't let Qunbound leak into Lisp.
8245 2012-02-07 Glenn Morris <rgm@gnu.org>
8247 * image.c (Fimagemagick_types): Doc fix.
8249 * image.c (imagemagick-render-type): Change it from a lisp object
8250 to an integer. Move the doc here from the lisp manual.

8255 * doc.c (store_function_docstring): Avoid applying docstring of
8256 alias to base function (Bug#2603).
8258 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
8260 * .gdbinit (pp1, pv1): Remove redundant defines.
8263 2012-02-04 Chong Yidong <cyd@gnu.org>

8280 before BEGV. (Bug#10696)
8282 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
8284 Handle overflow when computing char display width (Bug#9496).
8285 * character.c (char_width): Return EMACS_INT, not int.
8286 (char_width, c_string_width): Check for overflow when
8287 computing the width; this is possible now that individual
8288 characters can have unbounded width. Problem introduced
8289 by merge from Emacs 23 on 2012-01-19.
8291 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
8293 * dbusbind.c (Fdbus_register_method): Mention the return value

8306 2012-02-02 Kenichi Handa <handa@m17n.org>
8308 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
8309 0, do not call append_composite_glyph.

8313 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
8315 (x_produce_glyphs): If the component of a composition is a null
8316 string, set it->pixel_width to 1 to avoid zero-width glyph.

8320 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
8321 first 2 arguments are identical. This makes inserting large
8322 output from a subprocess an order of magnitude faster on
8323 MS-Windows, where all sbrk'ed memory is always contiguous.

8381 * character.c (char_width): New function.
8382 (Fchar_width, c_string_width, lisp_string_width):

8408 2012-01-11 Glenn Morris <rgm@gnu.org>
8410 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
8411 from load-path also when installation-directory is nil. (Bug#10208)
8413 2012-01-10 Glenn Morris <rgm@gnu.org>
8415 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.

8422 * xdisp.c (rows_from_pos_range): Accept additional argument
8423 DISP_STRING, and accept any glyph in a row whose object is that
8424 string as eligible for mouse highlight. Fixes mouse highlight of
8425 display strings from overlays. (Bug#10464)
8427 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
8429 emacs: fix an auto-save permissions race condition (Bug#10400)
8430 * fileio.c (auto_saving_dir_umask): New static var.
8431 (Fmake_directory_internal): Use it.
8432 (do_auto_save_make_dir): Set it, instead of invoking chmod after
8433 creating the directory. The old code temporarily assigns
8434 too-generous permissions to the directory.
8435 (do_auto_save_eh): Clear it.
8436 (Fdo_auto_save): Catch all errors, not just file errors, so
8437 that the var is always cleared.

8441 * search.c (scan_buffer): Pass character positions to
8442 know_region_cache, not byte positions. (Bug#6540)

8483 * xmenu.c (x_menu_wait_for_event): Use xg_select for Gtk3 so menus

8490 * callint.c (Fcall_interactively): Don't truncate prompt string.
8492 2011-12-23 Eli Zaretskii <eliz@gnu.org>
8494 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
8495 property that ends at ZV, so that the bidi iteration could be

8942 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
8943 is set, removing the need for VIRT_ADDRESS_VARIES.
8944 (PURE_P): Use a more-efficient implementation that needs just one

8959 (erase_phys_cursor, update_window_cursor, show_mouse_face)
8960 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
8961 behave as if the cursor position were at the window margin.
8963 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
8964 and the cursor position is out of bounds, behave as if the cursor
8965 position were at the window margin. (Bug#10075)
8967 2011-11-18 Chong Yidong <cyd@gnu.org>
8969 * window.c (Fwindow_combination_limit): Make first argument

9454 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
9456 2011-10-27 Chong Yidong <cyd@gnu.org>
9458 * gnutls.c (emacs_gnutls_deinit): New function.
9459 Deallocate credentials structures as well as calling gnutls_deinit.
9460 (Fgnutls_deinit, Fgnutls_boot): Use it.
9462 * process.c (make_process): Initialize GnuTLS credentials to NULL.
9463 (deactivate_process): Call emacs_gnutls_deinit.
9465 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9467 * image.c (x_create_x_image_and_pixmap):
9468 * w32.c (sys_rename, w32_delayed_load):
9469 * w32font.c (fill_in_logfont):
9470 * w32reg.c (x_get_string_resource): Silence compiler warnings.
9472 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
9474 * w32fns.c (w32_default_color_map): New function,
9475 extracted from Fw32_default_color_map.
9476 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
9478 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
9480 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
9482 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
9484 * keyboard.c (test_undefined): New function (bug#9751).
9485 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
9487 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
9489 * sysdep.c (init_sys_modes): Fix the check for the controlling
9490 terminal (Bug#6649).
9492 2011-10-20 Eli Zaretskii <eliz@gnu.org>
9494 * dispextern.h (struct bidi_it): New member next_en_type.
9496 * bidi.c (bidi_line_init): Initialize the next_en_type member.
9497 (bidi_resolve_explicit_1): When next_en_pos is valid for the
9498 current character, check also for next_en_type being WEAK_EN.
9499 (bidi_resolve_weak): Don't enter the expensive loop if the current
9500 position is before next_en_pos. Record the bidi type of the first
9501 non-ET, non-BN character we find, in addition to its position.
9502 (bidi_level_of_next_char): Invalidate next_en_type when
9503 next_en_pos is over-stepped.
9505 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
9507 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
9508 * editfns.c: Rewrite current-time-zone so that it invokes
9509 the equivalent of (format-time-string "%Z") to get the time zone name.
9510 This fixes a bug when the time zone name contains characters that
9511 need converting from the system time locale to Emacs internal format.
9512 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9513 that patch fixed format-time-string to do the conversion, but
9514 I forgot to fix current-time-zone.
9515 (format_time_string): New function, containing most of
9516 what Fformat_time_string used to contain.
9517 (Fformat_time_string): Rewrite in terms of format_time_string.
9518 This doesn't change this function's behavior.
9519 (current-time-zone): Rewrite to use format_time_string.
9520 This fixes the bug reported by Michael Schierl in
9521 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9522 Jason Rumney's 2007-06-07 change worked around this bug, but
9524 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9526 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9528 * xdisp.c (start_display): If the character at POS is displayed
9529 via a display vector, reset IT->current.dpvec_index to zero.
9530 (try_window_reusing_current_matrix): If a line ends in a display
9531 vector or the next line starts in a display vector, continue
9532 redrawing the window even though the character position of
9533 start_row was reached.
9536 2011-10-18 Chong Yidong <cyd@gnu.org>
9538 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9539 with nobreak-char-display too.
9541 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9543 Fix part 3 of bug#9771.
9544 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9545 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9546 non-neutral characters if the current character is a paragraph
9547 separator (a.k.a. Newline). This avoids running the same
9548 expensive loop twice, once when we consume the preceding newline
9549 and the other time when the line actually needs to be displayed.
9550 Avoid the loop when we see neutrals on the base embedding level
9551 following a character whose directionality is the same as the
9552 paragraph's. This avoids running the expensive loop when a line
9553 ends in a long sequence of neutrals, like control characters.
9554 Add assertion against STRONG_AL type. Slightly rearrange code
9555 that determines the type of a neutral given the first non-neutral
9557 (bidi_level_of_next_char): Set next_en_pos to zero when
9558 invalidating its info.
9560 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9562 * xdisp.c (push_display_prop): Determine whether to record string
9563 or buffer position by IT->string, not by IT->method. Allow
9564 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9565 (move_it_vertically_backward): Don't look for character position
9566 immediately after the newline when in a continuation line.
9569 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9571 * window.c (coordinates_in_window): Rewrite and delabelize
9572 vertical border check. (Bug#5357) (Bug#9618)
9574 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9576 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9577 errors in XSetWindowBorder (bug#9310).
9579 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9581 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9582 avoid crash when xmalloc overrun checking is enabled.
9584 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9586 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9587 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9588 cursor motion with <left> and <right> arrow keys.
9590 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9591 some callers set that themselves.
9593 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9595 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9596 display string and the previous row comes from the same string and
9597 is empty. (Bug#9739) (Bug#9738)
9599 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9601 * doc.c (get_doc_string): Encode file name (bug#9735).
9603 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9605 * bidi.c (bidi_level_of_next_char):
9606 * xdisp.c (get_visually_first_element): Remove old incorrect
9607 comments regarding the Unicode Line Separator character.
9609 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9611 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9613 * alloc.c (Fgc_status): Do not access beyond zombies array
9614 boundary if nzombies > MAX_ZOMBIES.
9615 * alloc.c (dump_zombies): Add missing format specifier.
9617 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9619 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9620 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9622 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9623 Some packages use them to denote characters with modifiers.
9625 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9627 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9628 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9629 matching a pp-number. Rename parameter var to var1.
9631 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9633 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9635 2011-10-08 Glenn Morris <rgm@gnu.org>
9637 * callint.c (Fcall_interactively): Give a more explicit error for the
9638 'c' case with a non-character input. (Bug#8479)
9640 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9642 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9644 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9645 lines that are hscrolled on the left.
9647 * dispnew.c (buffer_posn_from_coords): Account for a possible
9648 presence of header-line. (Bug#4426)
9650 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
9652 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
9653 Don't advertise functionality which we discourage or doesn't work.
9655 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
9657 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
9658 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
9659 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
9660 this makes Emacs dump core during garbage collection on rare
9661 occasions. sizeof is obviously inferior to offsetof here, so
9662 stick with offsetof.
9663 (GC_POINTER_ALIGNMENT): New macro.
9664 (mark_memory): Omit 3rd (offset) arg; caller changed.
9665 Don't assume EMACS_INT alignment is the same as pointer alignment.
9667 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
9669 * keyboard.c (read_key_sequence_remapped): New var.
9670 (read_key_sequence): Compute remapping in the right buffer.
9671 (command_loop_1): Use read_key_sequence's remapping directly.
9673 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
9675 * dired.c (file_name_completion): Don't expand file name.
9676 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
9677 before checking file name handler.
9679 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
9680 they've been requested explicitly (bug#9591).
9682 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
9684 * keymap.c (Fsingle_key_description): Use make_specified_string
9685 instead of build_string to build string from push_key_description.
9688 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9690 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
9691 This fixes a Y2038 bug on 64-bit hosts.
9692 * buffer.c (reset_buffer):
9693 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
9694 (Fclear_buffer_auto_save_failure):
9695 Use 0, not -1, to represent an unset failure time, since time_t
9696 might not be signed.
9698 Remove dependency on glibc malloc internals.
9699 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9700 Move back here from lisp.h, but with their new implementations.
9701 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9702 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
9703 * charset.c (charset_table_init): New static var.
9704 (syms_of_charset): Use it instead of xmalloc. This removes a
9705 dependency on glibc malloc internals. See Eli Zaretskii's comment in
9706 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
9707 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9708 Move back to alloc.c.
9709 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9710 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
9712 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
9714 * nsterm.m (windowDidResize): Call x_set_window_size only when
9715 ns_in_resize is true. Otherwise set pixelwidth/height and
9716 call change_frame_size (Bug#9628).
9718 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9720 Port --enable-checking=all to Fedora 14 x86-64.
9721 * charset.c (syms_of_charset): Also account for glibc malloc's
9722 internal overhead when calculating the initial malloc maximum.
9724 Port --enable-checking=all to Fedora 14 x86.
9725 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9727 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
9728 (overrun_check_realloc, overrun_check_free):
9729 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
9730 That way, xmalloc returns a properly-aligned pointer even if
9731 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
9732 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
9733 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
9734 into account when calculating the initial malloc maximum.
9735 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9736 Move here from alloc.c, so that charset.c can use it too.
9737 Properly align; the old code wasn't right for common 32-bit hosts
9738 when configured with --enable-checking=all.
9739 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9740 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
9742 2011-09-29 Eli Zaretskii <eliz@gnu.org>
9744 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
9747 2011-09-28 Eli Zaretskii <eliz@gnu.org>
9749 * xdisp.c (compute_display_string_end): If there's no display
9750 string at CHARPOS, return -1.
9752 * bidi.c (bidi_fetch_char): When compute_display_string_end
9753 returns a negative value, treat the character as a normal
9754 character not covered by a display string. (Bug#9624)
9756 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
9758 * lread.c (Fread_from_string): Fix typo in docstring.
9760 2011-09-27 Eli Zaretskii <eliz@gnu.org>
9762 * xdisp.c (handle_invisible_prop): If invisible text ends on a
9763 newline, reseat the iterator instead of bidi-iterating there one
9764 character at a time. (Bug#9610)
9765 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
9766 TO_CHARPOS if the bidi iterator is at base embedding level.
9768 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
9770 * lread.c (readevalloop): Use correct code for NBSP.
9771 (read1): Likewise. (Bug#9608)
9773 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
9775 * dbusbind.c (Fdbus_register_signal): When service is not
9776 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
9778 2011-09-25 Glenn Morris <rgm@gnu.org>
9780 * buffer.c (truncate-lines): Doc fix.
9782 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
9784 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
9785 (Fset_window_next_buffers): Doc fix.
9787 2011-09-24 Glenn Morris <rgm@gnu.org>
9789 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
9791 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
9793 Fix minor problems found by static checking.
9794 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
9795 * indent.c (Fvertical_motion): Fix == vs = typo.
9797 2011-09-24 Eli Zaretskii <eliz@gnu.org>
9799 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
9800 Default value is now t. Doc fix.
9802 * indent.c (Fvertical_motion): Compute and apply the overshoot
9803 logic when moving up, not only when moving down. Fix the
9804 confusing name and values of the it_overshoot_expected variable;
9805 logic changes accordingly. (Bug#9254) (Bug#9549)
9807 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
9808 CHARPOS is covered by a display string which includes newlines.
9809 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
9810 is covered by a display string with embedded newlines.
9812 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
9814 * dbusbind.c (Fdbus_register_signal): Add match rule to
9815 Vdbus_registered_objects_table. (Bug#9581)
9816 (Fdbus_register_method, Vdbus_registered_objects_table):
9819 2011-09-24 Jim Meyering <meyering@redhat.com>
9821 do not ignore write error for any output size
9822 The previous change was incomplete.
9823 While it makes emacs --batch detect the vast majority of stdout
9824 write failures, errors were still ignored whenever the output size is
9825 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
9826 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
9827 && echo FAIL: ignored write error
9828 FAIL: ignored write error
9829 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
9830 && echo FAIL: ignored write error
9831 FAIL: ignored write error
9832 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
9834 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
9836 * emacs.c (Fkill_emacs): In noninteractive mode exit
9837 non-successfully if a write error occurred on stdout. (Bug#9574)
9839 2011-09-21 Eli Zaretskii <eliz@gnu.org>
9841 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
9844 * dispextern.h (struct it): Update the comment documenting what
9847 2011-09-20 Eli Zaretskii <eliz@gnu.org>
9849 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
9850 a display string, extend search for cursor position to end of row.
9851 (find_row_edges): If the row ends in a newline from a display
9852 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
9853 Handle the case of a display string with multiple newlines.
9854 (Fcurrent_bidi_paragraph_direction): Fix search for previous
9855 non-empty line. Fixes confusing cursor motion with arrow keys at
9856 the beginning of a line that starts with whitespace.
9858 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9860 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
9863 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
9865 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
9868 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9870 * xdisp.c (display_line): Record maximum and minimum buffer
9871 positions even if no glyphs were produced (e.g., by a zero-width
9872 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
9873 buffer positions that will be removed from the glyph row because
9875 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
9876 column is beyond frame width: don't subtract 1 "pixel" when
9877 computing width of the stretch.
9878 (reseat_at_next_visible_line_start): Undo the change made on
9879 2011-09-17 that saved paragraph information and restored it after
9880 the call to `reseat'. (Bug#9545)
9882 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9884 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
9885 and turn window cursor on if cleared (Bug#9415).
9887 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
9889 * search.c (boyer_moore): Take unibyte characters from pattern
9890 literally. (Bug#9458)
9892 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9894 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
9896 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
9898 Fix minor problem found by static checking.
9899 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
9900 initialized, to pacify gcc -Wuninitialized.
9902 * fileio.c: Report proper errno when syscall falls.
9903 (Finsert_file_contents): Save and restore errno,
9904 so that report_file_error outputs the correct diagnostic.
9905 (Fwrite_region) [CLASH_DETECTION]: Likewise.
9907 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9909 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
9911 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9913 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
9914 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
9916 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9918 * xdisp.c (reseat_at_next_visible_line_start): Keep information
9919 about the current paragraph and restore it after the call to reseat.
9921 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
9922 (bidi_find_paragraph_start): Search back for paragraph beginning
9923 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
9924 (bidi_move_to_visually_next): Only trigger paragraph-related
9925 computations when the last character is a newline or at EOB, not
9926 just any NEUTRAL_B. (Bug#9470)
9928 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
9929 truncated lines if point is covered by a display string. (Bug#9524)
9931 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
9933 * xselect.c: Relax test for outgoing X longs (Bug#9498).
9934 (cons_to_x_long): New function.
9935 (lisp_data_to_selection_data): Use it. Correct the test for
9936 short-versus-long data; it was negated. Break out of vector
9937 loop, for efficiency, when a long datum is discovered.
9939 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
9941 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
9943 2011-09-16 Eli Zaretskii <eliz@gnu.org>
9945 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
9946 GCC PR/17406) by declaring this function with external scope.
9948 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9950 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
9951 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
9953 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
9955 * editfns.c (Fformat): Correctly handle text properties on "%%".
9957 2011-09-15 Eli Zaretskii <eliz@gnu.org>
9959 * xterm.c (x_draw_composite_glyph_string_foreground):
9960 * w32term.c (x_draw_composite_glyph_string_foreground):
9961 * term.c (encode_terminal_code):
9962 * composite.c (composition_update_it, get_composition_id):
9963 * xdisp.c (get_next_display_element)
9964 (fill_composite_glyph_string): Add comments about special meaning
9965 of TAB characters in a composition.
9967 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9969 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
9970 This occurs when processing a multibyte format.
9971 Problem reported by Wolfgang Jenker.
9973 2011-09-15 Johan Bockgård <bojohan@gnu.org>
9975 * xdisp.c (try_cursor_movement): Only check for exact match if
9976 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
9978 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9980 Remove unused external symbols.
9981 * dispextern.h (calc_pixel_width_or_height): Remove decl.
9982 * xdisp.c (calc_pixel_width_or_height): Now static.
9983 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
9984 * indent.c (check_display_width):
9985 * w32term.c: Fix comment to match code.
9986 * xterm.c, xterm.h (x_catching_errors): Remove.
9988 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9990 * xselect.c: Use signed conversions more consistently (Bug#9498).
9991 (selection_data_to_lisp_data): Assume incoming selection data are
9992 signed integers, not unsigned. This is to be consistent with
9993 outgoing selection data, which was modified to use signed integers
9994 in as part of the fix to Bug#9196 in response to Jan D.'s comment
9995 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
9996 expects long, not unsigned long.
9998 2011-09-14 Eli Zaretskii <eliz@gnu.org>
10000 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
10001 computation of loop end. Reported by Johan Bockgård
10004 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
10006 * frame.c (Fother_visible_frames_p): Function deleted.
10008 2011-09-12 Eli Zaretskii <eliz@gnu.org>
10010 * indent.c (compute_motion): Process display vector front to back
10011 rather than the other way around. (Bug#2496)
10013 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
10015 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
10017 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
10019 * minibuf.c (Fread_from_minibuffer): Doc fix.
10021 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10023 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
10024 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
10026 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
10028 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
10029 value for non-existent files.
10031 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10033 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10034 set its "size" to -1. This will set the modtime_size field of
10035 the corresponding buffer to -1, which is what
10036 verify-visited-file-modtime expects for files that do not exist.
10039 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
10041 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10043 * lisp.h: ... from here. push_key_description is no longer
10044 defined in keyboard.c, so its declaration should not be in
10045 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10046 logically belongs with push_key_description.
10048 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10050 * buffer.h: Include <sys/types.h> instead of <time.h>.
10051 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
10052 Problem reported by Herbert J. Skuhra.
10054 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
10056 * xml.c (parse_region): Make the parsing work for
10057 non-comment-starting XML files again (bug#9144).
10059 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
10061 * image.c (gif_load): Fix calculation of bottom and right corner.
10064 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10066 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10067 redisplay in small windows.
10069 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10071 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10073 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10075 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10076 Operate on live windows only.
10078 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10080 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10082 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10084 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10085 only under bidi iteration.
10087 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10089 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10091 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10093 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10094 Without this fix, the command to link temacs failed due to an
10095 undefined symbol __builtin_isnan. This is because
10096 /usr/include/iso/math_c99.h #defines isnan(x) to
10097 __builtin_isnan(x), but the bundled gcc, which identifies itself
10098 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10100 * floatfns.c (isnan): #undef, and then #define to a clone of
10102 (Fisnan): Always define, since it's always available now.
10103 (syms_of_floatfns): Always define isnan at the Lisp level.
10105 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10107 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10109 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10111 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10112 The previous code assumed that file offsets (off_t values) fit in
10113 EMACS_INT variables, which is not true on typical 32-bit hosts.
10114 The code messed up by falsely reporting buffer overflow in cases
10115 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10116 when "big" contains more than 2**29 bytes, even though this
10117 inserts just one byte and does not overflow the buffer.
10118 (Finsert_file_contents): Store file offsets as off_t
10119 values, not as EMACS_INT values. Check for overflow when
10120 converting between EMACS_INT and off_t. When checking for
10121 buffer overflow or for overlap, take the offsets into account.
10122 Don't use EMACS_INT for small values where int suffices.
10123 When checking for overlap, fix a typo: ZV was used where
10124 ZV_BYTE was intended.
10125 (Fwrite_region): Don't assume off_t fits into 'long'.
10126 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10128 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10130 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10132 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10134 sprintf-related integer and memory overflow issues (Bug#9412).
10136 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10137 (esprintf, exprintf, evxprintf): New functions.
10138 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10139 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10140 (modify_event_symbol): Do not assume that the length of
10141 name_alist_or_stem is safe to alloca and fits in int.
10142 (Fexecute_extended_command): Likewise for function name and binding.
10143 (Frecursion_depth): Wrap around reliably on integer overflow.
10144 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10145 since some callers pass EMACS_INT values.
10146 (Fsingle_key_description): Don't crash if symbol name contains more
10147 than MAX_ALLOCA bytes.
10148 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10149 (get_minibuffer): Arg is now EMACS_INT, not int.
10150 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10151 (esprintf, exprintf, evxprintf): New decls.
10152 * window.h (command_loop_level, minibuf_level): Reflect API changes.
10154 * dbusbind.c (signature_cat): New function.
10155 (xd_signature, Fdbus_register_signal):
10156 Do not overrun buffer; instead, report string overflow.
10158 * dispnew.c (add_window_display_history): Don't overrun buffer.
10159 Truncate instead; this is OK since it's just a log.
10161 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10162 even if the time zone offset is outlandishly large.
10163 Don't mishandle offset == INT_MIN.
10165 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10166 when creating daemon; the previous buffer-overflow check was incorrect.
10168 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10169 which has the guts of the old verror function.
10171 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10172 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10174 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10175 (font_unparse_xlfd): Don't blindly alloca long strings.
10176 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10177 fits in int, when using sprintf. Use single snprintf to count
10178 length of string rather than counting it via multiple sprintfs;
10179 that's simpler and more reliable.
10180 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10181 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10182 sprintf, in case result does not fit in int.
10184 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10185 (fontset_from_font): Print it.
10187 * frame.c (tty_frame_count): Now printmax_t, not int.
10188 (make_terminal_frame, set_term_frame_name): Print it.
10189 (x_report_frame_params): In X, window IDs are unsigned long,
10190 not signed long, so print them as unsigned.
10191 (validate_x_resource_name): Check for implausibly long names,
10192 and don't assume name length fits in 'int'.
10193 (x_get_resource_string): Don't blindly alloca invocation name;
10194 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10197 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10198 (xg_check_special_colors, xg_set_geometry):
10199 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10201 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10202 Use esprintf, not sprintf, in case result does not fit in int.
10204 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10205 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10206 it as a large positive number.
10207 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10208 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10210 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10211 in case result does not fit in int.
10213 * print.c (float_to_string): Detect width overflow more reliably.
10214 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10215 buffer overrun. Don't assume list length fits in 'int'. Treat
10216 print length of 0 as 0, not as infinity; to be consistent with other
10217 uses of print length in this function. Don't overflow print length
10218 index. Don't assume hash table size fits in 'long', or that
10219 vectorlike size fits in 'unsigned long'.
10221 * process.c (make_process): Use printmax_t, not int, to format
10222 process-name gensyms.
10224 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10226 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10227 to avoid potential buffer overrun.
10229 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10230 if X resource line is longer than 512 bytes.
10232 * xfns.c (x_window): Make sprintf buffer a bit bigger
10233 to avoid potential buffer overrun.
10235 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10237 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10239 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10241 Integer overflow fixes for scrolling, etc.
10242 Without these, Emacs silently mishandles large integers sometimes.
10243 For example, "C-u 4294967297 M-x recenter" was treated as if
10244 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10246 * xdisp.c (try_window_id): Check Emacs fixnum range before
10247 converting to 'int'.
10249 * window.c (window_scroll_line_based, Frecenter):
10250 Check that an Emacs fixnum is in range before assigning it to 'int'.
10251 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10252 values converted from Emacs fixnums.
10253 (Frecenter): Don't wrap around a line count if it is out of 'int'
10254 range; instead, treat it as an extreme value.
10255 (Fset_window_configuration, compare_window_configurations):
10256 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10258 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10259 that can exceed INT_MAX. Check that EMACS_INT value is in range
10260 before assigning it to the (possibly-narrower) index.
10261 (match_limit): Don't assume that a fixnum can fit in 'int'.
10263 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10266 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10267 (Fvertical_motion): Don't wrap around LINES values that don't fit
10268 in 'int'. Instead, treat them as extreme values. This is good
10269 enough for windows, which can't have more than INT_MAX lines anyway.
10271 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10273 * Require libxml/parser.h to avoid compilation warning.
10275 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10277 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10278 since this reportedly can destroy thread storage.
10280 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10282 * syntax.c (find_defun_start): Update all cache variables if
10283 exiting early (Bug#9401).
10285 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10287 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10289 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10290 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10291 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10293 * term.c (tty_append_glyph): New function.
10294 (produce_stretch_glyph): Static function and its prototype deleted.
10296 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10299 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10301 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10302 when checking :margin (Bug#9390).
10303 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10304 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10305 so that the name doesn't mislead. All uses changed.
10307 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10309 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
10312 2011-08-27 Eli Zaretskii <eliz@gnu.org>
10314 * xdisp.c (move_it_to): Don't bail out early when reaching
10315 position beyond to_charpos, if we are scanning backwards.
10316 (move_it_vertically_backward): When DY == 0, make sure we get to
10317 the first character in the line after the newline.
10319 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10321 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10322 (ccl_driver): Do not generate an out-of-range pointer.
10323 (Fccl_execute_on_string): Remove unnecessary check for
10324 integer overflow, noted by Stefan Monnier in
10325 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10326 Remove a FIXME that didn't need fixing.
10327 Simplify the newly-introduced buffer reallocation code.
10329 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10331 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10333 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10335 Integer and memory overflow issues (Bug#9196).
10337 * doc.c (get_doc_string): Rework so that
10338 get_doc_string_buffer_size is the actual buffer size, rather than
10339 being 1 less than the actual buffer size; this makes xpalloc more
10342 * image.c (x_allocate_bitmap_record, cache_image):
10343 * xselect.c (Fx_register_dnd_atom):
10344 Simplify previous changes by using xpalloc.
10346 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10347 since either will do and ptrdiff_t is convenient with xpalloc.
10349 * charset.c (charset_table_size)
10350 (struct charset_sort_data.priority): Now ptrdiff_t.
10351 (charset_compare): Don't overflow if priorities differ greatly.
10352 (Fsort_charsets): Don't assume list length fits in int.
10353 Check for size-calculation overflow when allocating sort data.
10354 (syms_of_charset): Allocate an initial charset table that is
10355 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10357 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10359 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10360 The actual value is always <= INT_MAX, and leaving it unsigned made
10361 overflow checking harder.
10363 * dispextern.h (struct glyph_matrix.rows_allocated)
10364 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10365 with xpalloc. The values are still always <= INT_MAX.
10367 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10369 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10370 (SAFE_NALLOCA): New macro.
10372 * region-cache.c (struct boundary.pos, find_cache_boundary)
10373 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10374 (set_cache_region, invalidate_region_cache)
10375 (revalidate_region_cache, know_region_cache, region_cache_forward)
10376 (region_cache_backward, pp_cache):
10377 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10378 so that ptrdiff_t * can be passed to xpalloc.
10379 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,

10398 because xmalloc/xrealloc may not return.
10399 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10400 now that we have proper integer overflow checking.
10401 (record_overlay_string, overlay_strings): Catch overflows when
10402 calculating size of overlay_str_buf.
10404 * callproc.c (Fcall_process): Check for size overflow when
10405 calculating size of args2.
10406 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.

10408 require adding more-complicated checks.
10410 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10411 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

10451 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10453 * emacs.c (main): Do not reallocate argv, since there is a null at
10454 the end that can be overwritten, and this way there's no need to
10455 worry about size-calculation overflow.
10456 (sort_args): Check for size-calculation overflow.
10458 * eval.c (init_eval_once, grow_specpdl): Don't update size until

10464 Check for integer overflow.
10465 (x_set_alpha): Do not assume XINT fits in int.
10467 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10468 This is for the members text_lines, text_cols, total_lines, total_cols,
10469 where the system imposes an 'int' limit.
10471 * fringe.c (Fdefine_fringe_bitmap):
10472 Don't update size until alloc works.

10477 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
10478 Check for size-calculation overflow.
10479 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10480 do, as we prefer signed integers.

10487 * gtkutil.h: Change prototypes to match the above.
10489 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

10585 (X_LONG_MIN): New macros.
10586 Use them to make the following changes clearer.
10587 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

10589 future maintainers not to raise the value too much later.
10590 (SELECTION_QUANTUM): Remove, replacing with ...
10591 (selection_quantum): ... new function, which avoids overflow.
10593 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10594 assumption that selection length fits in 'int'.

10611 Don't store size until memory allocation succeeds.
10612 (x_get_window_property): Plug memory leak on memory exhaustion.
10613 Don't double-block input; malloc is safe here. Don't assume 2**34
10614 - 4 fits in unsigned long. Add an xassert to check
10615 XGetWindowProperty overflow. Be more careful about overflow
10616 calculations, and distinguish size from memory overflow better.
10617 (receive_incremental_selection): When tracing, don't assume
10618 unsigned int is less than INT_MAX.
10619 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

10622 in the range -65535 through -1 fit in an X unsigned short.
10623 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10624 result parameters unless successful. Rely on cons_to_unsigned
10625 to report problems with elements; the old code wasn't right anyway.
10626 (x_check_property_data): Check for int overflow; we cannot use
10627 a wider type due to X limits.

10660 * lisp.h (hash_lookup, hash_put):
10661 * minibuf.c (Ftest_completion):
10662 Use ptrdiff_t for hash table indexes, not int (which is too
10663 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
10664 32-bit --with-wide-int hosts).
10666 * charset.c (Fdefine_charset_internal): Check for integer overflow.
10667 Add a FIXME comment about memory leaks.

10675 with outlandish widths.
10676 * character.h (sanitize_tab_width): Rename from sanitize_width,

10698 exceed limits imposed by XClientMessageEvent, as well as the usual
10699 ptrdiff_t and size_t limits.
10701 * keyboard.c: Overflow, signedness and related fixes.
10702 (make_lispy_movement): Use same integer type in forward decl
10703 that is used in the definition.
10704 (read_key_sequence, keyremap_step):
10705 Change bufsize argument back to int, undoing my 2011-03-30 change.
10706 We prefer signed types, and int is wide enough here.
10707 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
10708 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
10709 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
10710 length, not size_t. Use ptrdiff_t for index, not int.
10711 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
10712 possibility of integer overflow.

10740 Prefer int to unsigned where either will do.
10741 (tiff_handler): New function, combining the cores of the
10742 old tiff_error_handler and tiff_warning_handler.
10743 This function is rewritten to use vsnprintf and thereby avoid
10744 stack buffer overflows. It uses only the features of vsnprintf
10745 that are common to both POSIX and native Microsoft.
10746 (tiff_error_handler, tiff_warning_handler): Use it.
10747 (tiff_load, gif_load, imagemagick_load_image):
10748 Don't assume :index value fits in 'int'.

10764 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
10765 the display spec is of the form `(space ...)'.
10766 (handle_display_spec): Return the value returned by
10767 handle_single_display_spec, not just 1 or zero.
10768 (handle_single_display_spec): If the display spec is of the form
10769 `(space ...)', and specifies display in the text area, return 2
10771 (try_cursor_movement): Check for the need to scroll more
10772 accurately, and prefer exact match for point under bidi.
10773 Don't advance `row' beyond the last row of the window.

10791 buffers, return left-to-right.
10792 (set_cursor_from_row): Consider candidate row a win if its glyph
10793 represents a newline and point is on that newline. Fixes cursor
10794 positioning on the newline at EOL of R2L text within L2R
10795 paragraph, and vice versa.
10796 (try_cursor_movement): Check continued rows, in addition to
10797 continuation rows. Fixes unwarranted scroll when point enters a
10798 continued line of R2L text within an L2R paragraph, or vice versa.
10799 (cursor_row_p): Consider the case of point being equal to
10800 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
10801 from the end of a short line to the beginning of a continued line
10802 of R2L text within L2R paragraph.

10821 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
10822 extra slot even if the purpose is char-code-property-table.
10824 2011-08-23 Eli Zaretskii <eliz@gnu.org>
10826 * xdisp.c (redisplay_window): When computing centering_position,
10827 account for the height of the header line. (Bug#8874)
10829 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
10830 instead of CHAR_TO_BYTE. Fixes a crash when a completion
10831 candidate is selected by the mouse, and that candidate has a
10832 composed character under the mouse.
10834 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
10835 coordinates reported by pos-visible-in-window-p for a composed
10836 character in column zero.
10838 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

10846 composed buffer positions.
10848 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
10850 * image.c (gif_load): Don't assume that each subimage has the same
10851 dimensions as the base image. Handle disposal method that is
10852 "undefined" by the gif spec (Bug#9335).
10854 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
10856 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

10861 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
10862 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
10863 from an Org mode buffer to a Speedbar frame.
10865 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
10866 a composition, take its buffer position from IT->cmp_it.charpos.
10867 Fixes cursor positioning at the beginning of a line that begins
10868 with a composed character.
10870 2011-08-18 Eli Zaretskii <eliz@gnu.org>
10872 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
10873 character bidirectional type, use STRONG_L instead. Fixes crashes
10874 in a buffer produced by `describe-categories'.
10876 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
10877 members before the level stack, so they would be saved and
10878 restored when copying iterator state. Fixes incorrect reordering
10879 around TABs covered by display properties.
10881 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
10883 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

10888 (internal_condition_case_2, internal_condition_case_n):
10889 Remove unnecessary aborts (Bug#9081).
10891 2011-08-17 Eli Zaretskii <eliz@gnu.org>
10893 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
10894 has no `load' handler, try opening the file locally. (Bug#9311)
10896 2011-08-16 Ken Brown <kbrown@cornell.edu>
10898 * gmalloc.c: Expand comment.
10900 2011-08-16 Eli Zaretskii <eliz@gnu.org>

10916 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
10917 in the static heap.
10918 [CYGWIN] (special_realloc): New function.
10919 (_realloc_internal_nolock) [CYGWIN]: Use the new function on

10951 2011-08-14 Eli Zaretskii <eliz@gnu.org>
10953 * xdisp.c (move_it_in_display_line_to): Don't invoke
10954 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
10955 ppos_it. Fixes vertical cursor motion when line beginning is
10956 covered by an image. (Bug#9296)
10958 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
10960 * nsterm.h (ns_run_ascript): Declare.

10964 (ns_run_ascript): New function.
10965 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
10966 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
10967 the event loop. Get status from as_status (Bug#7276).
10969 * nsterm.m (sendEvent): If event is NSApplicationDefined and
10970 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
10971 the event loop (Bug#7276).
10973 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
10975 * gnutls.c (QCgnutls_bootprop_priority)

10977 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
10978 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
10979 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
10980 (QCgnutls_bootprop_verify_hostname_error)

10997 (Fnetwork_interface_list): Allocate in increments of bytes instead
10998 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
10999 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
11001 (struct ifflag_def): notrailers is smart on OSX.
11002 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
11003 Get hardware address with getifaddrs if available.
11005 2011-08-12 Eli Zaretskii <eliz@gnu.org>
11007 * xdisp.c (iterate_out_of_display_property): xassert that
11008 IT->position is set to within IT->object's boundaries. Break from
11009 the loop as soon as EOB is reached; avoids infloops in redisplay
11010 when IT->position is set up wrongly due to some bug.
11011 Set IT->current to match the bidi iterator unconditionally.
11012 (push_display_prop): Allow GET_FROM_STRING as IT->method on
11013 entry. Force push_it to save on the stack the current
11014 buffer/string position, to be restored by pop_it. Fix flags in
11015 the iterator structure wrt the object coming from a display
11016 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
11017 properties. (Bug#9284)
11019 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
11021 * fontset.c (fontset_get_font_group): Add proper type checks.

11034 no-display-properties-and-no-overlays under bidi display.
11035 Set disp_pos in the bidi iterator to avoid searches for display
11036 properties and overlays.
11038 2011-08-08 Chong Yidong <cyd@stupidchicken.com>

11049 restore_point_unwind (Bug#5984).
11051 2011-08-07 Juri Linkov <juri@jurta.org>
11053 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
11054 to show the arg `TIME' instead of `TIMEVAL'.
11056 2011-08-06 Eli Zaretskii <eliz@gnu.org>
11058 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
11059 display property strides EOL and includes a newline, as in
11060 longlines-mode. (Bug#9254)
11061 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
11062 word-wrap under bidirectional display. (Bug#9224)
11064 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
11065 is non-zero, even if the data buffer is NULL. Fixes a crash in
11066 vertical-motion with longlines-mode. (Bug#9254)
11068 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11070 * bidi.c <bidi_cache_total_alloc>: Now static.
11071 (bidi_initialize): Initialize bidi_cache_total_alloc.
11073 * xdisp.c (display_line): Release buffer allocated for shelved bidi
11076 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
11077 amount allocated this far in `bidi_cache_total_alloc'.
11078 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
11079 non-zero, only free the data buffer without restoring the cache
11080 contents. All callers changed.
11082 * dispextern.h (bidi_unshelve_cache): Update prototype.
11084 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
11085 (move_it_in_display_line, move_it_to)
11086 (move_it_vertically_backward, move_it_by_lines): Replace the call
11087 to xfree to an equivalent call to bidi_unshelve_cache.
11088 (move_it_in_display_line_to): Fix logic of returning
11089 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
11091 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11093 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
11094 came from a string character with a `cursor' property. (Bug#9229)

11108 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11110 * xterm.c (x_find_topmost_parent): New function.
11111 (x_set_frame_alpha): Find topmost parent window with
11112 x_find_topmost_parent and set the property there also (bug#9181).
11113 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
11115 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>

11141 for a display string or property. If found, set DISP_PROP_P
11144 * bidi.c (bidi_fetch_char): Accept an additional argument
11145 DISP_PROP_P, and pass it to compute_display_string_pos.
11146 Only handle text covered by a display string if DISP_PROP_P is returned
11147 non-zero. All callers of bidi_fetch_char changed.
11149 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
11151 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.

11175 * regex.c (re_comp): Protoize.
11176 (re_exec): Fix return type.
11177 (regexec): Fix type of `ret'. (Bug#9203)
11179 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11181 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
11182 This is needed if max-image-size is a floating-point number.
11184 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11186 * print.c (print_object): Print empty symbol as ##.

11231 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11233 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11234 Without this fix, if a signal arrives just after memory fills up,
11235 'malloc' might be invoked reentrantly.
11237 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11238 In other words, assume that every image size is allowed, on non-X
11239 hosts. This assumption is probably wrong, but it lets Emacs compile.
11241 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11243 * regex.c (re_iswctype): Convert return values to boolean.

11262 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11263 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11264 (bidi_find_other_level_edge):
11265 Use ptrdiff_t instead of EMACS_INT where either will do.
11266 This works better on 32-bit hosts configured --with-wide-int.
11267 (bidi_cache_ensure_space): Check for size-calculation overflow.
11268 Use % rather than repeated addition, for better worst-case speed.
11269 Don't set bidi_cache_size until after xrealloc returns, because it
11271 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11272 (bidi_cache_ensure_space): Also check that the bidi cache size
11273 does not exceed that of the largest Lisp string or buffer. See Eli
11274 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11276 * alloc.c (__malloc_size_t): Remove.
11277 All uses replaced by size_t. See Andreas Schwab's note
11278 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11280 * image.c: Improve checking for integer overflow.
11281 (check_image_size): Assume that f is nonnull, since
11282 it is always nonnull in practice. This is one less thing to
11283 worry about when checking for integer overflow later.
11284 (x_check_image_size): New function, which checks for integer
11285 overflow issues inside X.
11286 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11287 This removes the need for a memory_full check.
11288 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11289 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11290 (xbm_read_bitmap_data): Change locals back to 'int', since
11291 their values must fit in 'int'.
11292 (xpm_load_image, png_load, tiff_load):
11293 Invoke x_create_x_image_and_pixmap earlier,
11294 to avoid much needless work if the image is too large.
11295 (tiff_load): Treat overly large images as if
11296 x_create_x_image_and_pixmap failed, not as malloc failures.
11297 (gs_load): Use x_check_image_size.
11299 * gtkutil.c: Omit integer casts.
11300 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11301 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11303 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11305 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11306 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11307 would wrongly return t on a 64-bit host.
11309 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11310 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11311 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11312 and therefore cause GCC to emit a bogus diagnostic in some cases.
11314 * image.c: Integer signedness and overflow and related fixes.
11315 This is not an exhaustive set of fixes, but it's time to
11316 record what I've got.
11317 (lookup_pixel_color, check_image_size): Remove redundant decls.
11318 (check_image_size): Don't assume that arbitrary EMACS_INT values
11319 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11320 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11321 (tiff_load, imagemagick_load_image):
11322 Check for overflow in size calculations.
11323 (x_create_x_image_and_pixmap): Remove unnecessary test for
11324 xmalloc returning NULL; that can't happen.
11325 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11326 (xpm_color_bucket): Use better integer hashing function.
11327 (xpm_cache_color): Don't possibly over-allocate memory.
11328 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11329 (gif_memory_source):
11330 Use ptrdiff_t, not int or size_t, to record sizes.
11331 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11332 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11333 either works, as we prefer signed integers.
11334 (tiff_read_from_memory, tiff_write_from_memory):
11335 Return tsize_t, not size_t, since that's what the TIFF API wants.
11336 (tiff_read_from_memory): Don't fail simply because the read would
11337 go past EOF; instead, return a short read.
11338 (tiff_load): Omit no-longer-needed casts.
11339 (Fimagemagick_types): Don't assume size fits into 'int'.
11341 Improve hashing quality when configured --with-wide-int.
11342 * fns.c (hash_string): New function, taken from sxhash_string.
11343 Do not discard information about ASCII character case; this
11344 discarding is no longer needed.
11345 (sxhash-string): Use it. Change sig to match it. Caller changed.
11346 * lisp.h: Declare it.
11347 * lread.c (hash_string): Remove, since we now use fns.c's version.
11348 The fns.c version returns a wider integer if --with-wide-int is
11349 specified, so this should help the quality of the hashing a bit.
11351 * emacs.c: Integer overflow minor fix.
11352 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11353 Define only if GNU_LINUX.
11354 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11356 * dispnew.c: Integer signedness and overflow fixes.
11357 Remove unnecessary forward decls, that were a maintenance hassle.
11358 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11360 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11361 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11362 (prepare_desired_row, line_draw_cost):
11363 Use int, not unsigned, where either works.
11364 (save_current_matrix, restore_current_matrix):
11365 Use ptrdiff_t, not size_t, where either works.
11366 (init_display): Check for overflow more accurately, and without
11367 relying on undefined behavior.
11369 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11370 Remove, replacing with the new symbols in lisp.h. All uses changed.
11371 * fileio.c (make_temp_name):
11372 * filelock.c (lock_file_1, lock_file):
11373 * xdisp.c (message_dolog):
11374 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11375 Use pMd etc. instead.
11376 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11377 replacing the pWIDE etc. symbols removed from editfns.c.
11379 * keyboard.h (num_input_events): Now uintmax_t.
11380 This is (very slightly) less likely to mess up due to wraparound.
11383 * buffer.c: Integer signedness fixes.
11384 (alloc_buffer_text, enlarge_buffer_text):
11385 Use ptrdiff_t rather than size_t when either will do, as we prefer
11388 * alloc.c: Integer signedness and overflow fixes.
11389 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11390 (__malloc_size_t): Default to size_t, not to int.
11391 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11392 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11393 Prefer ptrdiff_t to size_t when either would do, as we prefer
11395 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11396 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11397 Now const. Initialize with values that are in range even if char
11399 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11400 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11401 These functions do the right thing with sizes > 2**32.
11402 (check_depth): Now ptrdiff_t, not int.
11403 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11404 Adjust to new way of storing sizes. Check for size overflow bugs
11406 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11407 slightly wrong anyway, as it missed one instance of
11408 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11409 (refill_memory_reserve): Omit needless cast to size_t.
11410 (mark_object_loop_halt): Mark as externally visible.
11412 * xselect.c: Integer signedness and overflow fixes.
11413 (Fx_register_dnd_atom, x_handle_dnd_message):
11414 Use ptrdiff_t, not size_t, since we prefer signed.
11415 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11416 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11417 x_dnd_atoms_size and x_dnd_atoms_length.
11419 * doprnt.c: Prefer signed to unsigned when either works.
11421 * doprnt.c (doprnt):
11423 * xdisp.c (vmessage):
11424 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11425 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11426 prefer signed arithmetic to avoid comparison confusion.
11427 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11428 but is a bit tricky.
11430 Assume freestanding C89 headers, string.h, stdlib.h.
11431 * data.c, doprnt.c, floatfns.c, print.c:
11432 Include float.h unconditionally.
11433 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11434 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11435 * regex.c: Likewise for stddef.h, string.h.
11436 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11437 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11438 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11439 (STDC_HEADERS): Remove obsolete defines.
11440 * sysdep.c: Include limits.h unconditionally.
11442 Assume support for memcmp, memcpy, memmove, memset.
11443 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11444 * regex.c (memcmp, memcpy):
11445 Remove; we assume C89 now.
11447 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11448 (__malloc_safe_bcopy): Remove; no longer needed.
11450 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11451 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11452 well either way, and we prefer signed to unsigned.
11454 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11456 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11457 closes the connection while we're reading (bug#9182).
11459 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11461 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11462 are specified (Bug#9168).
11464 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11466 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11467 Found by GCC static checking and --with-wide-int on a 32-bit host.
11469 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11471 * xdisp.c (compute_display_string_pos): Fix logic of caching
11472 previous display string position. Initialize cached_prev_pos to
11473 -1. Fixes slow-down at the beginning of a buffer.
11475 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11477 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11478 for attrs[LFACE_FONTSET_INDEX].
11480 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11482 * xml.c (parse_region): Remove unused local
11483 that was recently introduced.
11485 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11487 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11488 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11490 * xdisp.c (move_it_in_display_line_to): Record the best matching
11491 position for TO_CHARPOS while scanning the line, and restore it on
11492 exit if none of the characters scanned was an exact match.
11493 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11494 when exact match is impossible due to invisible text, and the
11495 lines are truncated.
11497 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11499 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11502 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11504 Fix a significant slow-down of cursor motion with C-n, C-p,
11505 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11506 auto-repeat under bidi redisplay in fontified buffers.
11507 * xdisp.c (compute_stop_pos_backwards): New function.
11508 (next_element_from_buffer): Call compute_stop_pos_backwards to
11509 find a suitable prev_stop when we find ourselves before
11511 (reseat): Don't look for prev_stop, as that could mean a very long
11513 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11514 <cached_disp_overlay_modiff>: Cache for last found display string
11516 (compute_display_string_pos): Return the cached position if asked
11517 about the same buffer in the same area of character positions, and
11518 the buffer wasn't changed since the time the display string
11519 position was cached.
11521 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11523 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11524 is an integer, which is important for empty lines. (Bug#9149)
11526 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11528 * frame.c (Fmodify_frame_parameters): In tty case, update the
11529 default face if necessary (Bug#4238).
11531 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11533 * editfns.c (Fstring_to_char): No need to explain what a character
11534 is in the docstring (Bug#6576).
11536 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11538 * xml.c (parse_region): Make sure we always return a tree.
11540 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11542 * xml.c (parse_region): If a document contains only comments,
11545 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11547 * xml.c (make_dom): Return comments, too.
11549 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11552 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11553 and the surrounding thread.
11554 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11555 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11556 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11558 * s/openbsd.h (BROKEN_SIGIO): Define.
11559 * unexelf.c (unexec) [__OpenBSD__]:
11560 Don't update the .mdebug section of the Alpha COFF symbol table.
11562 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11564 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11567 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11569 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11570 This fixes some race conditions on the permissions of any newly
11573 * alloc.c (valid_pointer_p): Use pipe, not open.
11574 This fixes some permissions issues when debugging.
11576 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11577 If fchown fails to set both uid and gid, try to set just gid,
11578 as that is sometimes allowed. Adjust the file's mode to eliminate
11579 setuid or setgid bits that are inappropriate if fchown fails.
11581 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11583 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11584 to compare Lisp_Objects.
11585 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11586 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11587 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11589 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11591 * lread.c (read_integer): Unread even EOF character.
11592 (read1): Likewise. Properly record start position of symbol.
11594 * lread.c (read1): Read `#:' as empty uninterned symbol if no
11595 symbol character follows.
11597 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11599 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11600 This works around a problem with the previous change to Fcopy_file.
11601 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11602 and without this change, GCC might complain about discarding
11603 fchown's return value.
11605 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11607 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11609 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11611 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11613 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11615 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11616 it's used from the C level.
11618 * process.c: Use the same condition for POLL_FOR_INPUT in both
11619 keyboard.c and process.c (bug#1858).
11621 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11623 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11624 (Fgnutls_boot): Use it.
11626 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11628 * doc.c (Fsubstitute_command_keys): Revert last change.
11630 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11632 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11633 quotes the next character, and doesn't affect other longer
11634 sequences (bug#8935).
11636 * lread.c (syms_of_lread): Clarify that is isn't only
11637 `eval-buffer' and `eval-defun' that's affected by
11638 `lexical-binding' (bug#8460).
11640 2011-07-15 Eli Zaretskii <eliz@gnu.org>
11642 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11643 bidi redisplay when a line includes both an image and is truncated.
11645 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11647 Fix minor problems found by static checking.
11648 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11649 (elsz): Now a signed constant, not a size_t var. We prefer signed
11650 types to unsigned, to avoid integer comparison confusion. Without
11651 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
11652 "cannot optimize loop, the loop counter may overflow", a symptom
11654 * indent.c (Fvertical_motion): Mark locals as initialized.
11655 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
11657 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
11659 * search.c (Fre_search_backward): Mention `case-fold-search' in
11660 all the re_search_* functions (bug#8138).
11662 * keyboard.c (Fopen_dribble_file): Document when the file is
11665 2011-07-14 Eli Zaretskii <eliz@gnu.org>
11667 * bidi.c (bidi_dump_cached_states): Fix format of displaying
11670 Support bidi reordering of display and overlay strings.
11671 * xdisp.c (compute_display_string_pos)
11672 (compute_display_string_end): Accept additional argument STRING.
11673 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
11674 (reseat_to_string): Initialize bidi_it->string.s and
11675 bidi_it->string.schars.
11676 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
11677 NULL (avoids a crash in bidi_paragraph_init).
11678 Initialize itb.string.lstring.
11679 (init_iterator): Call bidi_init_it only of a valid
11680 buffer position was specified. Initialize paragraph_embedding to
11682 (reseat_to_string): Initialize the bidi iterator.
11683 (display_string): If we need to ignore text properties of
11684 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
11685 original value of -1 will not work with bidi.)
11686 (compute_display_string_pos): First arg is now struct
11687 `text_pos *'; all callers changed. Support display properties on
11689 (compute_display_string_end): Support display properties on Lisp
11691 (init_iterator, reseat_1, reseat_to_string): Initialize the
11692 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
11693 when iterating on a string not from display properties).
11694 (compute_display_string_pos, compute_display_string_end):
11695 Fix calculation of the object to scan. Fixes an error when using
11697 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
11698 base_level_stop; instead, set base_level_stop to BEGV.
11699 Fixes crashes in vertical-motion.
11700 (next_element_from_buffer): Improve commentary for when
11701 the iterator is before prev_stop.
11702 (init_iterator): Initialize bidi_p from the default value of
11703 bidi-display-reordering, not from buffer-local value. Use the
11704 buffer-local value only if initializing for buffer iteration.
11705 (handle_invisible_prop): Support invisible properties on strings
11706 that are being bidi-reordered.
11707 (set_iterator_to_next): Support bidi reordering of C strings and
11709 (next_element_from_string): Support bidi reordering of Lisp
11711 (handle_stop_backwards): Support Lisp strings as well.
11712 (display_string): Support display of R2L glyph rows.
11713 Use IT_STRING_CHARPOS when displaying from a Lisp string.
11714 (init_iterator): Don't initialize it->bidi_p for strings
11716 (reseat_to_string): Initialize it->bidi_p for strings here.
11717 (next_element_from_string, next_element_from_c_string)
11718 (next_element_from_buffer): Add xassert's for correspondence
11719 between IT's object being iterated and it->bidi_it.string
11721 (face_before_or_after_it_pos): Support bidi iteration.
11722 (next_element_from_c_string): Handle the case of the first string

12177 * alloc.c (mark_buffer):
12178 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
12179 (clone_per_buffer_values): Don't assume that
12180 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
12181 This isn't true in general, and it's particularly not true
12182 if Emacs is configured with --with-wide-int.
12183 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
12184 New macros, used in the buffer.c change.

12218 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
12220 Random fixes. E.g., (random) never returned negative values.
12221 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
12222 subseconds part to the entropy, as that's a bit more random.
12223 Prefer signed to unsigned, since the signedness doesn't matter and
12224 in general we prefer signed. When given a limit, use a
12225 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12226 latter isn't right if USE_2_TAGS_FOR_INTS.
12227 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12228 not 0..VALMASK. Don't discard "excess" bits that random () returns.
12230 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
12232 * textprop.c (text_property_stickiness):
12233 Obey Vtext_property_default_nonsticky.

12240 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
12241 This is more efficient than Ffile_directory_p and avoids a minor race.
12243 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
12245 * buffer.c (Foverlay_put): Say what the return value is
12248 * fileio.c (barf_or_query_if_file_exists): Check first if the file
12249 is a directory before asking whether to use the file name
12251 (barf_or_query_if_file_exists): Make the "File is a directory"
12252 error be more correct.
12254 * fns.c (Frequire): Remove the mention of the .gz files, since
12255 that's installation-specific, but keep the mention of
12256 `get-load-suffixes'.
12258 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
12260 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

12266 (syms_of_gnutls): Remove duplicate DEFSYM for
12267 Qgnutls_bootprop_verify_hostname_error, an error for
12268 Qgnutls_bootprop_verify_error (which is no longer used).
12270 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
12271 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
12272 Also (re)move comments that are misplaced or no longer relevant.
12274 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12276 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

12335 (syms_of_keymap): Defsubr make-composed-keymap.
12336 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

12373 * eval.c (struct backtrace): Simplify and port the data structure.
12374 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12375 signed bit field, as this assumption is not portable and it makes
12376 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12377 "char debug_on_exit : 1" as this is not portable either; instead,
12378 use the portable "unsigned int debug_on_exit : 1". Remove unused
12379 member evalargs. Remove obsolete comments about cc bombing out.
12381 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

12600 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
12601 Mark as externally visible.
12602 * dispnew.c (check_window_matrix_pointers): Now static.
12603 * dispnew.c (window_to_frame_vpos):
12604 * xfns.c (unwind_create_frame):
12605 * xterm.c (x_check_font): Remove unused local.
12606 * scroll.c (CHECK_BOUNDS):
12607 * xfaces.c (cache_fache): Rename local to avoid shadowing.
12608 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
12609 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
12610 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
12611 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
12613 (debug_method_add): Use va_list and vsprintf rather than relying
12614 on undefined behavior with wrong number of arguments.
12615 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12616 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12617 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12618 since we're not interested in debugging glyphs with old libraries.
12619 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12620 GCC 4.6.0's static checking.
12622 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12624 Integer overflow and signedness fixes (Bug#8873).
12625 A few related buffer overrun fixes, too.

12633 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
12634 (x_create_bitmap_from_xpm_data):
12635 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
12636 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
12638 * xfaces.c (load_pixmap):
12639 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
12640 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
12641 (.bitmaps_last, struct x_output.icon_bitmap):
12642 Use ptrdiff_t, not int, for bitmap indexes.
12643 (x_allocate_bitmap_record): Check for size overflow.
12644 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
12646 Use ptrdiff_t, not int, for overlay counts.
12647 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
12648 * editfns.c (overlays_around, get_pos_property):
12649 * textprop.c (get_char_property_and_overlay):
12650 * xdisp.c (next_overlay_change, note_mouse_highlight):
12651 * xfaces.c (face_at_buffer_position):
12652 * buffer.c (OVERLAY_COUNT_MAX): New macro.
12653 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
12654 (Fnext_overlay_change, Fprevious_overlay_change)
12655 (mouse_face_overlay_overlaps, Foverlays_in):
12656 Use ptrdiff_t, not int, for sizes.
12657 (overlays_at, overlays_in): Check for size-calculation overflow.
12659 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
12661 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
12662 (x_session_initialize): Do not assume string length fits in int.
12664 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
12665 This is unlikely, but can occur if DPI is outlandish.
12667 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
12668 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
12670 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
12671 * xrdb.c (magic_file_p, search_magic_path):
12672 Omit last arg SUFFIX; it was always 0. All callers changed.
12673 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
12675 * xfont.c (xfont_match): Avoid need for strlen.
12677 * xfns.c: Don't assume strlen fits in int.
12678 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
12680 * xdisp.c (message_log_check_duplicate): Return intmax_t,
12681 not unsigned long, as we prefer signed integers. All callers changed.
12682 Detect integer overflow in repeat count.
12683 (message_dolog): Don't assume print length fits in 39 bytes.
12684 (display_mode_element): Don't assume strlen fits in int.
12686 * termcap.c: Don't assume sizes fit in int and never overflow.
12687 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
12688 (gobble_line): Check for size-calculation overflow.
12690 * minibuf.c (Fread_buffer):
12691 * lread.c (intern, intern_c_string):
12692 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
12693 Don't assume string length fits in int.
12695 * keyboard.c (parse_tool_bar_item):
12696 * gtkutil.c (style_changed_cb): Avoid need for strlen.
12698 * font.c: Don't assume string length fits in int.
12699 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
12700 Use ptrdiff_t, not int.
12701 (font_intern_prop): Don't assume string length fits in int.
12702 Don't assume integer property fits in fixnum.
12703 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
12705 * filelock.c: Fix some buffer overrun and integer overflow issues.
12706 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
12707 Reformulate so as not to need the command string.
12708 Invoke gzip -cd rather than gunzip, as it's more portable.
12709 (lock_info_type, lock_file_1, lock_file):
12710 Don't assume pid_t and time_t fit in unsigned long.
12711 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
12712 (current_lock_owner): Prefer signed type for sizes.
12713 Use memcpy, not strncpy, where memcpy is what is really wanted.
12714 Don't assume (via atoi) that time_t and pid_t fit in int.
12715 Check for time_t and/or pid_t out of range, e.g., via a network share.
12716 Don't alloca where an auto var works fine.
12718 * fileio.c: Fix some integer overflow issues.
12719 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
12720 Don't assume string length fits in int.
12721 (directory_file_name): Don't assume string length fits in long.
12722 (make_temp_name): Don't assume pid fits in int, or that its print
12723 length is less than 20.
12725 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
12727 * coding.c (make_subsidiaries): Don't assume string length fits in int.
12729 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
12731 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
12732 We prefer signed integers, even for size calculations.
12734 * emacs.c: Don't assume string length fits in 'int'.
12735 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
12736 (main): Don't invoke strlen when not needed.
12738 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
12739 (XD_DEBUG_MESSAGE): Don't waste a byte.
12741 * callproc.c (getenv_internal_1, getenv_internal)
12742 (Fgetenv_internal):
12743 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
12745 * lread.c (invalid_syntax): Omit length argument.
12746 All uses changed. This doesn't fix a bug, but it simplifies the
12747 code away from its former Hollerith-constant appearance, and it's
12748 one less 'int' to worry about when looking at integer-overflow issues.
12749 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
12751 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
12752 This didn't break anything, but it didn't help either.
12753 It's confusing to put a bogus integer in a place where the actual
12754 value does not matter.
12755 (LIST_END_P): Remove unused macro and its bogus comment.
12756 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
12758 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
12759 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
12761 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
12762 We prefer signed types, and the value cannot exceed the EMACS_INT
12763 range anyway (because otherwise the length would not be representable).
12764 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
12765 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
12766 This avoids a GCC warning when WIDE_EMACS_INT.
12768 * indent.c (sane_tab_width): New function.
12769 (current_column, scan_for_column, Findent_to, position_indentation)
12770 (compute_motion): Use it. This is just for clarity.
12771 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
12773 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
12775 * lisp.h (lint_assume): New macro.
12776 * composite.c (composition_gstring_put_cache):
12777 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
12779 * editfns.c, insdel.c:
12780 Omit unnecessary forward decls, to simplify future changes.
12782 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
12784 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
12786 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
12787 Use much-faster test for byte-length change.
12788 Don't assume string byte-length fits in 'int'.
12789 Check that character arg fits in 'int'.
12790 (mapcar1): Declare byte as byte, for clarity.
12792 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
12794 * fns.c (concat): Catch string overflow earlier.
12795 Do not rely on integer wraparound.
12797 * dispextern.h (struct it.overlay_strings_charpos)
12798 (struct it.selective): Now EMACS_INT, not int.
12799 * xdisp.c (forward_to_next_line_start)
12800 (back_to_previous_visible_line_start)
12801 (reseat_at_next_visible_line_start, next_element_from_buffer):
12802 Don't arbitrarily truncate the value of 'selective' to int.
12804 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
12806 * composite.c: Don't truncate sizes to 'int'.
12807 (composition_gstring_p, composition_reseat_it)
12808 (composition_adjust_point): Use EMACS_INT, not int.
12809 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
12810 not EMACS_UINT, for indexes.
12812 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
12814 * buffer.c: Include <verify.h>.
12815 (struct sortvec.priority, struct sortstr.priority):
12816 Now EMACS_INT, not int.
12817 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
12818 (struct sortstr.size, record_overlay_string)
12819 (struct sortstrlist.size, struct sortlist.used):
12820 Don't truncate size to int.
12821 (record_overlay_string): Check for size-calculation overflow.
12822 (init_buffer_once): Check at compile-time, not run-time.
12824 2011-06-22 Jim Meyering <meyering@redhat.com>
12826 Don't leak an XBM-image-sized buffer
12827 * image.c (xbm_load): Free the image buffer after using it.
12829 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
12832 * composite.c (find_automatic_composition): Omit needless 'return 0;'
12833 that Sun C diagnosed.
12834 * fns.c (secure_hash): Fix pointer signedness issue.
12835 * intervals.c (static_offset_intervals): New function.
12836 (offset_intervals): Use it.
12838 2011-06-21 Leo Liu <sdl.web@gmail.com>
12841 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
12844 * fns.c (secure_hash): Rename from crypto_hash_function and change
12845 the first arg to accept symbols.
12846 (Fsecure_hash): New primitive.
12847 (syms_of_fns): New symbols.
12849 2011-06-20 Deniz Dogan <deniz@dogan.se>
12851 * process.c (Fset_process_buffer): Clarify return value in
12854 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
12856 * dispnew.c (add_window_display_history): Use BVAR.
12858 * xdisp.c (debug_method_add): Use BVAR.
12859 (check_window_end, dump_glyph_matrix, dump_glyph)
12860 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
12862 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
12865 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
12866 check till after the cache is created in init_frame_faces.
12868 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
12870 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
12872 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
12874 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
12875 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
12876 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
12878 Improve buffer-overflow checking (Bug#8873).
12879 * fileio.c (Finsert_file_contents):
12880 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
12881 Remove the old (too-loose) buffer overflow checks.
12882 They weren't needed, since make_gap checks for buffer overflow.
12883 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
12884 The old code merely checked for Emacs fixnum overflow, and relied
12885 on undefined (wraparound) behavior. The new code avoids undefined
12886 behavior, and also checks for ptrdiff_t and/or size_t overflow.
12888 * editfns.c (Finsert_char): Don't dump core with very negative counts.
12889 Tune. Don't use wider integers than needed. Don't use alloca.
12890 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
12892 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
12894 * insdel.c, lisp.h (buffer_overflow): New function.
12895 (insert_from_buffer_1, replace_range, replace_range_2):
12896 * insdel.c (make_gap_larger):
12897 * editfns.c (Finsert_char):
12898 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
12900 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
12902 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
12904 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
12906 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
12907 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
12909 * fileio.c: Don't assume EMACS_INT fits in off_t.
12910 (emacs_lseek): New static function.
12911 (Finsert_file_contents, Fwrite_region): Use it.
12912 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
12914 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
12916 * fns.c: Don't overflow int when computing a list length.
12917 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
12918 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
12919 truncation on 64-bit hosts. Check for QUIT every
12920 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
12921 faster and is responsive enough.
12922 (Flength): Report an error instead of overflowing an integer.
12923 (Fsafe_length): Return a float if the value is not representable
12924 as a fixnum. This shouldn't happen except in contrived situations.
12925 (Fnthcdr, Fsort): Don't assume list length fits in int.
12926 (Fcopy_sequence): Don't assume vector length fits in int.
12928 * alloc.c: Check that resized vectors' lengths fit in fixnums.
12929 (header_size, word_size): New constants.
12930 (allocate_vectorlike): Don't check size overflow here.
12931 (allocate_vector): Check it here instead, since this is the only
12932 caller of allocate_vectorlike that could cause overflow.
12933 Check that the new vector's length is representable as a fixnum.
12935 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
12936 The previous code was bogus. For example, next_almost_prime (32)
12937 returned 39, which is undesirable as it is a multiple of 3; and
12938 next_almost_prime (24) returned 25, which is a multiple of 5 so
12939 why was the code bothering to check for multiples of 7?
12941 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
12943 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
12945 Variadic C functions now count arguments with ptrdiff_t.
12946 This partly undoes my 2011-03-30 change, which replaced int with size_t.
12947 Back then I didn't know that the Emacs coding style prefers signed int.
12948 Also, in the meantime I found a few more instances where arguments
12949 were being counted with int, which may truncate counts on 64-bit
12950 machines, or EMACS_INT, which may be unnecessarily wide.
12951 * lisp.h (struct Lisp_Subr.function.aMANY)
12952 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
12953 Arg counts are now ptrdiff_t, not size_t.
12954 All variadic functions and their callers changed accordingly.
12955 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
12956 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
12957 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
12958 * callint.c (Fcall_interactively): Check arg count for overflow,
12959 to avoid potential buffer overrun. Use signed char, not 'int',
12960 for 'varies' array, so that we needn't bother to check its size
12961 calculation for overflow.
12962 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
12963 * eval.c (apply_lambda):
12964 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
12965 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
12966 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
12968 * callint.c (Fcall_interactively): Don't use index var as event count.
12970 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
12971 * mem-limits.h (SIZE): Remove; no longer used.
12973 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
12975 Remove unnecessary casts.
12976 * xterm.c (x_term_init):
12977 * xfns.c (x_set_border_pixel):
12978 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
12979 These aren't needed now that we assume ANSI C.
12981 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
12982 It's more likely to cause problems (due to unsigned overflow)
12985 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
12987 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
12989 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
12991 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
12993 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
12995 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
12997 GLYPH_CODE_FACE returns EMACS_INT, not int.
12998 * dispextern.h (merge_faces):
12999 * xfaces.c (merge_faces):
13000 * xdisp.c (get_next_display_element, next_element_from_display_vector):
13001 Don't assume EMACS_INT fits in int.
13003 * character.h (CHAR_VALID_P): Remove unused parameter.
13004 * fontset.c, lisp.h, xdisp.c: All uses changed.
13006 * editfns.c (Ftranslate_region_internal): Omit redundant test.
13008 * fns.c (concat): Minor tuning based on overflow analysis.
13009 This doesn't fix any bugs. Use int to hold character, instead
13010 of constantly refetching from Emacs object. Use XFASTINT, not
13011 XINT, for value known to be a character. Don't bother comparing
13012 a single byte to 0400, as it's always less.
13014 * floatfns.c (Fexpt):
13015 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
13017 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
13020 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
13022 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
13023 Without this fix, on a 64-bit host (aset S 0 4294967386) would
13024 incorrectly succeed when S was a string, because 4294967386 was
13025 truncated before it was used.
13027 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13028 Otherwise, an out-of-range integer could cause undefined behavior
13031 * composite.c: Use int, not EMACS_INT, for characters.
13032 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13033 EMACS_INT, for values that are known to be in character range.
13034 This doesn't fix any bugs but is the usual style inside Emacs and
13035 may generate better code on 32-bit machines.
13037 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13038 This is for reasons similar to the recent CHAR_STRING fix.
13039 * charset.c (Fencode_char): Check that character arg is actually
13040 a character. Pass an int to ENCODE_CHAR.
13041 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13042 wider than 'int', as a compile-time check to prevent future regressions
13045 * character.c (char_string): Remove unnecessary casts.
13047 Make sure a 64-bit char is never passed to CHAR_STRING.
13048 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13049 by silently ignoring the top 32 bits, allowing some values
13050 that were far too large to be valid characters.
13051 * character.h: Include <verify.h>.
13052 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13053 arguments are no wider than unsigned, as a compile-time check
13054 to prevent future regressions in this area.
13056 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
13057 (Fsubst_char_in_region):
13059 * xdisp.c (decode_mode_spec_coding):
13060 Adjust to CHAR_STRING's new requirement.
13061 * editfns.c (Finsert_char, Fsubst_char_in_region):
13062 * fns.c (concat): Check that character args are actually
13063 characters. Without this test, these functions did the wrong
13064 thing with wildly out-of-range values on 64-bit hosts.
13066 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13067 These casts should not be needed on 32-bit hosts, either.
13068 * keyboard.c (read_char):
13069 * lread.c (Fload): Remove casts to unsigned.
13071 * lisp.h (UNSIGNED_CMP): New macro.
13072 This fixes comparison bugs on 64-bit hosts.
13073 (ASCII_CHAR_P): Use it.
13074 * casefiddle.c (casify_object):
13075 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
13076 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
13077 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
13078 * dispextern.h (FACE_FROM_ID):
13079 * keyboard.c (read_char): Use UNSIGNED_CMP.
13081 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
13082 not to EMACS_INT, to avoid GCC warning.
13084 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13086 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13087 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
13088 isn't needed on 32-bit machines.
13090 * buffer.c (Fgenerate_new_buffer_name):
13091 Use EMACS_INT for count, not int.
13092 (advance_to_char_boundary): Return EMACS_INT, not int.
13094 * data.c (Qcompiled_function): Now static.
13096 * window.c (window_body_lines): Now static.
13098 * image.c (gif_load): Rename local to avoid shadowing.
13100 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
13101 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
13102 * alloc.c (make_save_value): Integer argument is now of type
13103 ptrdiff_t, not int.
13104 (mark_object): Use ptrdiff_t, not int.
13105 * lisp.h (pD): New macro.
13106 * print.c (print_object): Use it.
13108 * alloc.c: Use EMACS_INT, not int, to count objects.
13109 (total_conses, total_markers, total_symbols, total_vector_size)
13110 (total_free_conses, total_free_markers, total_free_symbols)
13111 (total_free_floats, total_floats, total_free_intervals)
13112 (total_intervals, total_strings, total_free_strings):
13113 Now EMACS_INT, not int. All uses changed.
13114 (Fgarbage_collect): Compute overall total using a double, so that
13115 integer overflow is less likely to be a problem. Check for overflow
13116 when converting back to an integer.
13117 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
13118 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
13119 These were 'int' variables that could overflow on 64-bit hosts;
13120 they were never used, so remove them instead of repairing them.
13121 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
13122 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
13123 Previously, this ceilinged at INT_MAX, but that doesn't work on
13125 (allocate_pseudovector): Don't use EMACS_INT when int would do.
13127 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
13128 (allocate_vectorlike): Check for ptrdiff_t overflow.
13129 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13130 when a (possibly-narrower) signed value would do just as well.
13131 We prefer using signed arithmetic, to avoid comparison confusion.
13133 * alloc.c: Catch some string size overflows that we were missing.
13134 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
13135 for convenience in STRING_BYTES_MAX.
13136 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
13137 The definition here is exact; the one in lisp.h was approximate.
13138 (allocate_string_data): Check for string overflow. This catches
13139 some instances we weren't catching before. Also, it catches
13140 size_t overflow on (unusual) hosts where SIZE_MAX <= min
13141 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
13142 and ptrdiff_t and EMACS_INT are both 64 bits.
13144 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
13145 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
13146 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
13148 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
13150 * alloc.c (Fmake_string): Check for out-of-range init.
13152 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
13154 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
13156 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
13158 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
13159 xg_get_default_scrollbar_width.
13161 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
13162 (int_gtk_range_get_value): Move to the scroll bar part of the file.
13163 (style_changed_cb): Call update_theme_scrollbar_width and call
13164 x_set_scroll_bar_default_width and xg_frame_set_char_size for
13165 all frames (Bug#8505).
13166 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
13167 Call gtk_window_set_resizable if HAVE_GTK3.
13168 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
13169 and height if HAVE_GTK3 (Bug#8505).
13170 (scroll_bar_width_for_theme): New variable.
13171 (update_theme_scrollbar_width): New function.
13172 (xg_get_default_scrollbar_width): Move code to
13173 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

13176 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
13178 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

13185 * window.c (temp_output_buffer_show): Call display_buffer with
13186 second argument Vtemp_buffer_show_specifiers and reset latter
13187 immediately after the call.
13188 (Vtemp_buffer_show_specifiers): New variable.
13189 (auto_window_vscroll_p, next_screen_context_lines)
13190 (Vscroll_preserve_screen_position): Remove leading asterisks from

13733 (bidi_level_of_next_char): Don't try to lookup the cache for the
13734 next/previous character if nothing is cached there yet, or if we
13735 were just reseat()'ed to a new position.
13737 * xdisp.c (set_cursor_from_row): Set start and stop points
13738 according to the row's direction when priming the loop that looks
13739 for the glyph on which to display cursor.

13741 (display_prop_intangible_p): Reimplement to call
13742 handle_display_spec instead of single_display_spec_intangible_p.

13753 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
13754 value of a `display' property is a "replacing spec".
13755 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
13756 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
13757 the display property, but just return a value indicating whether
13758 the display property will replace the characters it covers.
13759 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
13760 frame_window_p members of struct bidi_it.

13786 * gnutls.c: Use Emacs's memory allocators.
13787 Without this change, the gnutls library would invoke malloc etc.
13788 directly, which causes problems on non-SYNC_INPUT hosts, and which
13789 runs afoul of improving memory_full behavior. (Bug#8761)
13790 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
13791 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
13792 xfree instead of the default malloc, realloc, free.
13793 (Fgnutls_boot): No need to check for memory allocation failure,
13794 since xmalloc does that for us.

13818 * alloc.c (allocate_vectorlike):
13819 Check for overflow in vector size calculations.
13820 * ccl.c (ccl_driver):
13821 Check for overflow when converting EMACS_INT to int.

13823 need to be updated by these changes.
13824 * fns.c (make_hash_table, maybe_resize_hash_table):
13825 Check for integer overflow with large hash tables.
13826 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
13827 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
13828 (SXHASH_REDUCE): New macro.
13829 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
13830 Use it instead of discarding useful hash info with large hash values.
13831 (sxhash_float): New function.
13832 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
13833 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
13834 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
13835 Rewrite to use FIXNUM_BITS, as this simplifies things.
13836 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
13837 Adjust signatures to match updated version of code.
13838 (consing_since_gc): Now EMACS_INT, since a single hash table can
13839 use more than INT_MAX bytes.

13888 Make it possible to run ./temacs.
13890 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
13891 syms_of_callproc does the same thing. Remove test for
13892 "initialized", do it in the caller.

13900 (Qmetadata): New var.
13901 * data.c (Qbuffer): Don't make it static.
13902 (syms_of_data): Use DEFSYM.
13904 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
13906 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
13907 (CCL_CODE_MIN): New macro.
13909 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
13911 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
13913 * eval.c (Qdebug): Now static.
13914 * lisp.h (Qdebug): Remove decl. This reverts a part of the
13915 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
13916 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
13918 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
13920 * image.c: Various fixes to ImageMagick code comments.
13921 (Fimagemagick_types): Doc fix.
13923 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
13925 Minor fixes prompted by GCC 4.6.0 warnings.
13927 * xselect.c (converted_selections, conversion_fail_tag): Now static.
13929 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
13930 (x_clipboard_manager_save_all): Move extern decl to ...
13931 * xterm.h: ... here, so that it can be checked for consistency.
13933 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
13935 * xselect.c (x_clipboard_manager_save_frame)
13936 (x_clipboard_manager_save_all): New functions.
13937 (Fx_clipboard_manager_save): Lisp function deleted.
13939 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
13940 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
13942 * xterm.h: Update prototype.
13944 2011-05-28 William Xu <william.xwl@gmail.com>
13946 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
13947 exiting (Bug#8239).
13949 2011-05-28 Jim Meyering <meyering@redhat.com>
13951 Avoid a sign-extension bug in crypto_hash_function.
13952 * fns.c (to_uchar): Define.
13953 (crypto_hash_function): Use it to convert some newly-signed
13954 variables to unsigned, to avoid sign-extension bugs. For example,
13955 without this change, (md5 "truc") would evaluate to
13956 45723a2aff78ff4fff7fff1114760e62 rather than the expected
13957 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
13958 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
13960 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13962 Integer overflow fixes.
13964 * dbusbind.c: Serial number integer overflow fixes.
13965 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
13966 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
13967 to hold a serial number that is too large for a fixnum.
13968 (Fdbus_method_return_internal, Fdbus_method_error_internal):
13969 Check for serial numbers out of range. Decode any serial number
13970 that was so large that it became a float. (Bug#8722)
13972 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
13973 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13974 Use XFASTINT rather than XUINT when numbers are nonnegative.
13975 (xd_append_arg, Fdbus_method_return_internal):
13976 (Fdbus_method_error_internal): Likewise. Also, for unsigned
13977 arguments, check that Lisp number is nonnegative, rather than
13978 silently wrapping negative numbers around. (Bug#8722)
13979 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
13982 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
13984 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
13986 ccl: Add integer overflow checks.
13987 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
13988 (IN_INT_RANGE): New macros.
13989 (ccl_driver): Use them to check for integer overflow when
13990 decoding a CCL program. Many of the new checks are whether XINT (x)
13991 fits in int; it doesn't always, on 64-bit hosts. The new version
13992 doesn't catch all possible integer overflows, but it's an
13993 improvement. (Bug#8719)
13995 * alloc.c (make_event_array): Use XINT, not XUINT.
13996 There's no need for unsigned here.
13998 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
13999 This follows up to the 2011-05-06 change that substituted uintptr_t
14000 for EMACS_INT. This case wasn't caught back then.
14002 Rework Fformat to avoid integer overflow issues.
14003 * editfns.c: Include <float.h> unconditionally, as it's everywhere
14004 now (part of C89). Include <verify.h>.
14005 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
14006 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
14007 (Fformat): Avoid the prepass trying to compute sizes; it was only
14008 approximate and thus did not catch overflow reliably. Instead, walk
14009 through the format just once, formatting and computing sizes as we go,
14010 checking for integer overflow at every step, and allocating a larger
14011 buffer as needed. Keep track separately whether the format is
14012 multibyte. Keep only the most-recently calculated precision, rather
14013 than them all. Record whether each argument has been converted to
14014 string. Use EMACS_INT, not int, for byte and char and arg counts.
14015 Support field widths and precisions larger than INT_MAX. Avoid
14016 sprintf's undefined behavior with conversion specifications such as %#d
14017 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
14018 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
14019 formatting out-of-range floating point numbers with int
14020 formats. (Bug#8668)
14022 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
14024 * data.c: Avoid integer truncation in expressions involving floats.
14025 * data.c: Include <intprops.h>.
14026 (arith_driver): When there's an integer overflow in an expression
14027 involving floating point, convert the integers to floating point
14028 so that the resulting value does not suffer from catastrophic
14029 integer truncation. For example, on a 64-bit host (* 4
14030 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14031 Do not rely on undefined behavior after integer overflow.
14033 merge count_size_as_multibyte, parse_str_to_multibyte
14034 * character.c, character.h (count_size_as_multibyte):
14035 Rename from parse_str_to_multibyte; all uses changed.
14036 Check for integer overflow.
14037 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14038 since it's now a duplicate of the other. This is more of
14039 a character than a buffer op, so better that it's in character.c.
14040 * fns.c, print.c: Adjust to above changes.
14042 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14044 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14046 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14048 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14049 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14050 (x_clipboard_manager_save): Now static.
14051 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14053 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14054 (crypto_hash_function): Now static.
14055 Fix pointer signedness problems. Avoid unnecessary initializations.
14057 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14059 * termhooks.h (Vselection_alist): Make it terminal-local.
14061 * terminal.c (create_terminal): Initialize it.
14063 * xselect.c: Support for clipboard managers.
14064 (Vselection_alist): Move to termhooks.h as terminal-local var.
14065 (LOCAL_SELECTION): New macro.
14066 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14067 (symbol_to_x_atom): Remove gratuitous arg.
14068 (x_handle_selection_request, lisp_data_to_selection_data)
14069 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14070 (x_own_selection, x_get_local_selection, x_convert_selection):
14071 New arg, specifying work frame. Use terminal-local Vselection_alist.
14072 (some_frame_on_display): Delete unused function.
14073 (Fx_own_selection_internal, Fx_get_selection_internal)
14074 (Fx_disown_selection_internal, Fx_selection_owner_p)
14075 (Fx_selection_exists_p): New optional frame arg.
14076 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14077 (x_handle_selection_clear): Don't treat other terminals with the
14078 same keyboard specially. Use the terminal-local Vselection_alist.
14079 (x_clear_frame_selections): Use Frun_hook_with_args.
14081 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14083 * xterm.h: Add support for those atoms.
14085 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14087 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14088 (converted_selections, conversion_fail_tag): New global variables.
14089 (x_selection_request_lisp_error): Free the above.
14090 (x_get_local_selection): Remove unnecessary code.
14091 (x_reply_selection_request): Args changed; handle arbitrary array
14092 of converted selections stored in converted_selections.
14093 Separate the XChangeProperty and SelectionNotify steps.
14094 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14095 (x_convert_selection): New function.
14096 (x_handle_selection_event): Simplify.
14097 (x_get_foreign_selection): Don't ignore incoming requests while
14098 waiting for an answer; this will fail when we implement
14099 SAVE_TARGETS, and seems unnecessary anyway.
14100 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14101 (Vx_sent_selection_functions): Doc fix.
14103 2011-05-26 Leo Liu <sdl.web@gmail.com>
14105 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14107 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14109 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14111 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14112 for fringe update if it has periodic bitmap.
14113 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14114 and fringe_bitmap_periodic_p.
14116 * fringe.c (get_fringe_bitmap_data): New function.
14117 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14118 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14119 row. Mark glyph row for fringe update if periodicity changed.
14121 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14122 for fringe update unless it has periodic bitmap.
14124 2011-05-25 Kenichi Handa <handa@m17n.org>
14126 * xdisp.c (get_next_display_element): Set correct it->face_id for
14127 a static composition.
14129 2011-05-24 Leo Liu <sdl.web@gmail.com>
14132 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
14134 * fns.c (crypto_hash_function, Fsha1): New function.
14135 (Fmd5): Use crypto_hash_function.
14136 (syms_of_fns): Add Ssha1.
14138 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14140 * gnutls.c: Remove unused macros.
14141 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14142 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14143 Remove macros that are defined and never used.
14144 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14146 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14148 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14149 (Fx_get_selection_internal): Minor cleanup.
14150 (Fx_own_selection_internal): Rename arguments for consistency with
14153 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14155 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
14157 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14159 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
14161 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14163 * dispnew.c (scrolling_window): Don't exclude the case that the
14164 last enabled row in the desired matrix touches the bottom boundary.
14166 2011-05-21 Glenn Morris <rgm@gnu.org>
14168 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
14169 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
14170 and add some more files.
14172 2011-05-20 Eli Zaretskii <eliz@gnu.org>
14174 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
14175 report_file_error introduced by the change from 2011-05-07.
14177 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14179 * systime.h (Time): Define only if emacs is defined.
14180 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14181 where the include path doesn't have X11/X.h by default. See
14182 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14184 2011-05-20 Kenichi Handa <handa@m17n.org>
14186 * composite.c (find_automatic_composition): Fix previous change.
14188 2011-05-20 Glenn Morris <rgm@gnu.org>
14190 * lisp.mk: New file, split from Makefile.in.
14191 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14192 (shortlisp): Remove.
14193 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14195 2011-05-19 Glenn Morris <rgm@gnu.org>
14197 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14198 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14199 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14200 (lisp): Set the order to that of loadup.el.
14201 (shortlisp): Make it a copy of $lisp.
14202 (SOME_MACHINE_LISP): Remove.
14203 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14204 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14206 2011-05-18 Kenichi Handa <handa@m17n.org>
14208 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14209 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14210 (find_automatic_composition): Mostly rewrite for efficiency.
14212 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14214 * makefile.w32-in: Update dependencies.
14216 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14218 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14219 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14221 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14223 Fix some integer overflow issues, such as string length overflow.
14225 * insdel.c (count_size_as_multibyte): Check for string overflow.
14227 * character.c (lisp_string_width): Check for string overflow.
14228 Use EMACS_INT, not int, for string indexes and lengths; in
14229 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14230 the resulting string length overflows an EMACS_INT; instead,
14231 report a string overflow if no precision given. When checking for
14232 precision exhaustion, use a check that cannot possibly have
14233 integer overflow. (Bug#8675)
14234 * character.h (lisp_string_width): Adjust to new signature.
14236 * alloc.c (string_overflow): New function.
14237 (Fmake_string): Use it. This doesn't change behavior, but saves
14238 a few bytes and will simplify future changes.
14239 * character.c (string_escape_byte8): Likewise.
14240 * lisp.h (string_overflow): New decl.
14242 Fixups, following up to the user-interface timestamp change.
14243 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14244 for UI timestamps, instead of unsigned long.
14245 * msdos.c (mouse_get_pos): Likewise.
14246 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14247 * w32gui.h (Time): Define by including "systime.h" rather than by
14248 declaring it ourselves. (Bug#8664)
14250 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14251 * image.c (clear_image_cache): Likewise.
14253 * term.c (term_mouse_position): Don't assume time_t wraparound.
14255 Be more systematic about user-interface timestamps.
14256 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14257 and sometimes 'EMACS_UINT', to represent these timestamps.
14258 This change causes it to use 'Time' uniformly, as that's what X uses.
14259 This makes the code easier to follow, and makes it easier to catch
14260 integer overflow bugs such as Bug#8664.
14261 * frame.c (Fmouse_position, Fmouse_pixel_position):
14262 Use Time, not unsigned long, for user-interface timestamps.
14263 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14264 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14265 * keyboard.h (last_event_timestamp): Likewise.
14266 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14267 * menu.h (xmenu_show): Likewise.
14268 * term.c (term_mouse_position): Likewise.
14269 * termhooks.h (struct input_event.timestamp): Likewise.
14270 (struct terminal.mouse_position_hook): Likewise.
14271 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14272 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14273 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14274 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14275 what it was before.
14276 * menu.h, termhooks.h: Include "systime.h", for Time.
14278 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14279 Don't assume that the difference between two unsigned long values
14280 can fit into an integer. At this point, we know button_down_time
14281 <= event->timestamp, so the difference must be nonnegative, so
14282 there's no need to cast the result if double-click-time is
14283 nonnegative, as it should be; check that it's nonnegative, just in
14284 case. This bug is triggered when events are more than 2**31 ms
14285 apart (about 25 days). (Bug#8664)
14287 * xselect.c (last_event_timestamp): Remove duplicate decl.
14288 (x_own_selection): Remove needless cast to unsigned long.
14290 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14291 that always fit in int. Use a sentinel instead of a counter, to
14292 avoid a temp and to allay GCC's concerns about possible int overflow.
14293 * frame.h (struct frame): Use int for menu_bar_items_used
14294 instead of EMACS_INT, since it always fits in int.
14296 * menu.c (grow_menu_items): Check for int overflow.
14298 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14300 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14301 Before, the code was not consistent. These values cannot exceed
14302 2**31 - 1 so there's no need to make them unsigned.
14303 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14304 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14305 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14307 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14309 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14310 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14311 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14312 presumably because the widths might not match.
14314 * window.c (size_window): Avoid needless test at loop start.
14316 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14318 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14320 2011-05-12 Drew Adams <drew.adams@oracle.com>
14322 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14324 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14326 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14327 `width' to `bar_area_x' and `bar_area_width', respectively.
14328 (x_scroll_run): Take account of fringe background extension.
14330 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14331 Rename local vars `left' and `width' to `bar_area_x' and
14332 `bar_area_width', respectively.
14333 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14334 background extension.
14336 2011-05-10 Jim Meyering <meyering@redhat.com>
14338 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14340 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14342 * image.c (Finit_image_library): Return t for built-in image types,
14343 like pbm and xbm. (Bug#8640)
14345 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14347 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14349 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14351 * w32console.c (Fset_screen_color): Doc fix.
14352 (Fget_screen_color): New function.
14353 (syms_of_ntterm): Defsubr it.
14355 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14356 unlink the temporary file if Fcall_process didn't create it in the
14358 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14359 child process will be redirected to a file specified with `:file'.
14360 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14361 cue to call_process_cleanup not to close that handle.
14363 2011-05-07 Ben Key <bkey76@gmail.com>
14365 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14366 one of two shell specific rules, either bootstrap-temacs-CMD or
14367 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14368 to the previous implementation of the bootstrap-temacs rule.
14369 The bootstrap-temacs-CMD rule is similar to the previous
14370 implementation of the bootstrap-temacs rule except that it
14371 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14374 These changes, along with some changes to nt/configure.bat,
14375 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14376 earlier fix to add support for --cflags and --ldflags options
14377 that include quotes so that it works whether make uses cmd or
14380 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14382 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14383 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14385 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14386 a string. Handle both cases.
14387 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14388 (Fdbus_register_method): Use Qinvalid_function.
14390 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14392 * makefile.w32-in: Update dependencies.
14393 (LISP_H): Add inttypes.h and stdin.h.
14394 (PROCESS_H): Add unistd.h.
14396 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14398 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14399 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14401 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14403 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14405 * term.c (vfatal): Remove stray call to va_end.
14406 It's not needed and the C Standard doesn't allow it here anyway.
14408 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14409 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14411 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14414 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14416 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14418 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14420 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14422 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14424 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14425 * charset.c (Fdefine_charset_internal): Don't initialize
14426 charset.code_space[15]. The value was garbage, on hosts with
14427 32-bit int (Bug#8600).
14429 * lread.c (read_integer): Be more consistent with string-to-number.
14430 Use string_to_number to do the actual conversion; this avoids
14431 rounding errors and fixes some other screwups. Without this fix,
14432 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14433 (digit_to_number): Move earlier, for benefit of read_integer.
14434 Return -1 if the digit is out of range for the base, -2 if it is
14435 not a digit in any supported base. (Bug#8602)
14437 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14439 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14440 to match comment at start of function. This also removes a
14441 GCC warning about overflow in a 32+64-bit port.
14443 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14445 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14446 Reported by Stefan Monnier in
14447 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14448 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14449 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14451 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14452 (EMACS_UINTPTR): Likewise, with uintptr_t.
14454 * lisp.h: Prefer 64-bit EMACS_INT if available.
14455 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14456 on 32-bit hosts that have 64-bit int, so that they can access
14458 However, temporarily disable this change unless the temporary
14459 symbol WIDE_EMACS_INT is defined.
14461 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14463 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14464 This removes an assumption that EMACS_INT and long are the same
14465 width as pointers. The assumption is true for Emacs porting targets
14466 now, but we want to make other targets possible.
14467 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14468 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14469 In the rest of the code, change types of integers that hold casted
14470 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14471 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14472 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14473 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14474 No need to cast type when ORing.
14475 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14476 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14477 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14478 assume EMACS_INT is the same width as char *.
14479 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14480 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14481 Remove no-longer-needed casts.
14482 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14483 (xg_tool_bar_help_callback, xg_make_tool_item):
14484 Use EMACS_INTPTR to hold an integer
14485 that will be cast to void *; this can avoid a GCC warning
14486 if EMACS_INT is not the same width as void *.
14487 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14488 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14489 (current_message_1, set_message_1):
14490 Use a local to convert to proper width without a cast.
14491 * xmenu.c (dialog_selection_callback): Likewise.
14493 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14494 Also, don't assume VALBITS / RAND_BITS is less than 5,
14495 and don't rely on undefined behavior when shifting a 1 left into
14497 * lisp.h (get_random): Change signature to match.
14499 * lread.c (hash_string): Use size_t, not int, for hash computation.
14500 Normally we prefer signed values; but hashing is special, because
14501 it's better to use unsigned division on hash table sizes so that
14502 the remainder is nonnegative. Also, size_t is the natural width
14503 for hashing into memory. The previous code used 'int', which doesn't
14504 retain enough info to hash well into very large tables.
14505 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14507 * dbusbind.c: Don't possibly lose pointer info when converting.
14508 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14509 Use XPNTR rather than XHASH, so that the high-order bits of
14510 the pointer aren't lost when converting through void *.
14512 * eval.c (Fautoload): Don't double-shift a pointer.
14514 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14516 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14518 * gnutls.c (DEF_GNUTLS_FN):
14519 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14521 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14523 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14526 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14528 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14529 New version that can reserve upto 2GB of heap space.
14531 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14533 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14535 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14537 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14538 `gnutls_certificate_set_x509_key_file'.
14540 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
14542 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
14543 Update dependencies.
14545 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14547 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14548 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14549 Remove unused parameter `fildes'.
14550 * process.c (read_process_output, send_process): Don't pass it.
14552 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14554 Fix previous change: the library cache is defined in w32.c.
14555 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14556 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14558 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14560 Implement dynamic loading of GnuTLS on Windows.
14562 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14563 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14564 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14567 * gnutls.c (Qgnutls_dll): Define.
14568 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
14569 (gnutls_*): Declare function pointers.
14570 (init_gnutls_functions): New function to initialize function pointers.

14573 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14574 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
14575 (emacs_gnutls_write, emacs_gnutls_read)
14576 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14577 (Fgnutls_available_p): New function.
14578 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
14579 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
14580 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
14582 * image.c: Include w32.h.
14583 (Vimage_type_cache): Delete.

14586 (w32_delayed_load): Move to w32.c.
14588 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
14590 * w32.c (QCloaded_from, Vlibrary_cache): Define.
14591 (w32_delayed_load): Move from image.c. When loading a library, record
14592 its filename in the :loaded-from property of the library id.
14593 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
14594 Initialize and staticpro them.
14595 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
14597 * process.c: Include lisp.h before w32.h, not after.
14598 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
14599 instead of gnutls_record_check_pending.
14601 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
14603 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
14605 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
14606 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
14609 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
14611 * xterm.c (x_set_frame_alpha): Do not set property on anything
14612 else than FRAME_X_OUTER_WINDOW (Bug#8608).
14614 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14616 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
14618 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14620 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

14634 * sysdep.c (wait_for_termination_1): Make static.
14635 (wait_for_termination, interruptible_wait_for_termination):
14636 Move after wait_for_termination_1.
14638 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
14640 * sysdep.c (interruptible_wait_for_termination): New function
14641 which is like wait_for_termination, but allows keyboard
14644 * callproc.c (Fcall_process): Add (:file "file") as an option for
14646 (Fcall_process_region): Ditto.
14648 2011-04-30 Eli Zaretskii <eliz@gnu.org>
14650 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
14651 rather than `XVECTOR (FOO)->size'.
14653 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
14654 inttypes.h, as a gnulib replacement is used if it not available in
14657 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14659 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
14660 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
14661 of MOST_POSITIVE_FIXNUM. (Bug#8528)
14663 * coding.c (coding_alloc_by_realloc): Error out if destination
14664 will grow beyond MOST_POSITIVE_FIXNUM.
14665 (decode_coding_emacs_mule): Abort if there isn't enough place in

14674 aborting when %lld or %lll format is passed.
14675 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
14676 %llo or %llx format is passed. (Bug#8545)
14678 * window.c (window_scroll_line_based): Use a marker instead of
14679 simple variables to record original value of point. (Bug#7952)
14681 * doprnt.c (doprnt): Fix the case where a multibyte sequence
14682 produced by %s or %c overflows available buffer space. (Bug#8545)
14684 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
14686 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
14687 (SIZE_MAX): Move defn after all includes, as they might #define it.
14689 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14691 * w32.c (init_environment): Warn about defaulting HOME to C:\.

14715 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
14717 * makefile.w32-in: Update dependencies.
14719 2011-04-27 Eli Zaretskii <eliz@gnu.org>
14721 Improve `doprnt' and its usage. (Bug#8545)
14722 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
14723 `format_end'. Remove support for %l as a conversion specifier.
14724 Don't use xrealloc. Improve diagnostics when the %l size modifier
14725 is used. Update the commentary.
14727 * eval.c (verror): Simplify calculation of size_t.
14729 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
14732 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
14734 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
14737 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14739 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
14740 This makes this file independent of the recent pseudovector change.
14742 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
14744 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
14746 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
14747 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
14748 Remove unused local.
14749 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
14751 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
14752 GCC 4.6.0 optimizes based on type-based alias analysis.
14753 For example, if b is of type struct buffer * and v of type struct
14754 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
14755 != &v->size, and therefore "v->size = 1; b->size = 2; return
14756 v->size;" must therefore return 1. This assumption is incorrect
14757 for Emacs, since it type-puns struct Lisp_Vector * with many other
14758 types. To fix this problem, this patch adds a new type struct
14759 vectorlike_header that documents the constraints on layout of vectors
14760 and pseudovectors, and helps optimizing compilers not get fooled
14761 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
14762 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
14763 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
14765 (XSETPVECTYPE): Rewrite in terms of new macro.
14766 (XSETPVECTYPESIZE): New macro, specifying both type and size.
14767 This is a bit clearer, and further avoids the possibility of
14768 undesirable aliasing.
14769 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
14770 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
14771 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
14772 since Lisp_Subr is a special case (no "next" field).
14773 (ASIZE): Now uses header.size rather than size.
14774 All previous uses of XVECTOR (foo)->size replaced to use this macro,
14775 to avoid the hassle of writing XVECTOR (foo)->header.size.
14776 (struct vectorlike_header): New type.
14777 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
14778 object, to help avoid aliasing.
14779 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
14780 (SUBRP): Likewise, since Lisp_Subr is a special case.
14781 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
14782 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
14783 (struct Lisp_Hash_Table): Combine first two members into a single
14784 struct vectorlike_header member. All uses of "size" and "next" members
14785 changed to be "header.size" and "header.next".
14786 * buffer.h (struct buffer): Likewise.
14787 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
14788 * frame.h (struct frame): Likewise.
14789 * process.h (struct Lisp_Process): Likewise.
14790 * termhooks.h (struct terminal): Likewise.
14791 * window.c (struct save_window_data, struct saved_window): Likewise.
14792 * window.h (struct window): Likewise.
14793 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
14794 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
14795 * buffer.c (init_buffer_once): Likewise.
14796 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
14798 * process.c (Fformat_network_address): Use local var for size,
14801 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
14803 Make the Lisp reader and string-to-float more consistent (Bug#8525)
14804 * data.c (atof): Remove decl; no longer used or needed.
14805 (digit_to_number): Move to lread.c.
14806 (Fstring_to_number): Use new string_to_number function, to be
14807 consistent with how the Lisp reader treats infinities and NaNs.
14808 Do not assume that floating-point numbers represent EMACS_INT
14809 without losing information; this is not true on most 64-bit hosts.
14810 Avoid double-rounding errors, by insisting on integers when
14811 parsing non-base-10 numbers, as the documentation specifies.
14812 * lisp.h (string_to_number): New decl, replacing ...
14813 (isfloat_string): Remove.
14814 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
14815 (read1): Do not accept +. and -. as integers; this
14816 appears to have been a coding error. Similarly, do not accept
14817 strings like +-1e0 as floating point numbers. Do not report
14818 overflow for integer overflows unless the base is not 10 which
14819 means we have no simple and reliable way to continue.
14820 Break out the floating-point parsing into a new
14821 function string_to_number, so that Fstring_to_number parses
14822 floating point numbers consistently with the Lisp reader.
14823 (digit_to_number): Move here from data.c. Make it static inline.
14824 (E_CHAR, EXP_INT): Remove, replacing with ...
14825 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
14826 (string_to_number): New function, replacing isfloat_string.
14827 This function checks for valid syntax and produces the resulting
14828 Lisp float number too. Rework it so that string-to-number
14829 no longer mishandles examples like "1.0e+". Use strtoumax,
14830 so that overflow for non-base-10 numbers is reported only when
14831 there's no portable and simple way to convert to floating point.
14833 * textprop.c (set_text_properties_1): Rewrite for clarity,
14834 and to avoid GCC warning about integer overflow.
14836 * intervals.h (struct interval): Use EMACS_INT for members
14837 where EMACS_UINT might cause problems. See
14838 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
14839 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
14840 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
14842 (offset_intervals): Tell GCC not to worry about length overflow
14843 when negating a negative length.
14845 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
14846 (overrun_check_free): Likewise.
14848 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
14849 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
14852 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14853 (gnutls_make_error): Rename local to avoid shadowing.
14854 (gnutls_emacs_global_deinit): ifdef out; not used.
14855 (Fgnutls_boot): Use const for pointer to readonly storage.
14856 Comment out unused local. Fix pointer signedness problems.
14858 * lread.c (openp): Don't stuff size_t into an 'int'.
14859 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
14860 about possible signed overflow.
14862 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14863 (GDK_KEY_g): Don't define if already defined.
14864 (xg_prepare_tooltip): Avoid pointer signedness problem.
14865 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
14867 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
14868 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
14870 * xfns.c (Fx_window_property): Simplify a bit,
14871 to make a bit faster and to avoid GCC 4.6.0 warning.
14872 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
14874 * fns.c (internal_equal): Don't assume size_t fits in int.
14876 * alloc.c (compact_small_strings): Tighten assertion a little.
14878 Replace pEd with more-general pI, and fix some printf arg casts.
14879 * lisp.h (pI): New macro, generalizing old pEd macro to other
14880 conversion specifiers. For example, use "...%"pI"d..." rather
14881 than "...%"pEd"...".
14882 (pEd): Remove. All uses replaced with similar uses of pI.
14883 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
14884 * alloc.c (check_pure_size): Don't overflow by converting size to int.
14885 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
14886 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
14887 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
14888 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
14889 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
14891 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
14892 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
14893 * print.c (safe_debug_print, print_object): Likewise.
14894 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
14896 Use pI instead of if-then-else-abort. Use %p to avoid casts,
14897 avoiding the 0 flag, which is not portable.
14898 * process.c (Fmake_network_process): Use pI to avoid cast.
14899 * region-cache.c (pp_cache): Likewise.
14900 * xdisp.c (decode_mode_spec): Likewise.
14901 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
14902 behavior on 64-bit hosts with printf arg.
14903 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
14904 (x_stop_queuing_selection_requests): Likewise.
14905 (x_get_window_property): Don't truncate byte count to an 'int'
14908 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
14909 here, since it parses constructs like leading '-' and spaces,
14910 which are not wanted; and it overflows with large numbers.
14911 Instead, simply match F[0-9]+, which is what is wanted anyway.
14913 * alloc.c: Remove unportable assumptions about struct layout.
14914 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
14915 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
14916 (allocate_vectorlike, make_pure_vector): Use the new macros,
14917 plus offsetof, to remove unportable assumptions about struct layout.
14918 These assumptions hold on all porting targets that I know of, but
14919 they are not guaranteed, they're easy to remove, and removing them
14920 makes further changes easier.
14922 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
14923 This doesn't fix a bug but makes the code clearer.
14924 (string_overrun_cookie): Now const. Use initializers that
14925 don't formally overflow signed char, to avoid warnings.
14926 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
14927 can cause Emacs to crash when string overrun checking is enabled.
14928 (allocate_buffer): Don't assume sizeof (struct buffer) is a
14929 multiple of sizeof (EMACS_INT); it need not be, if
14930 alignof(EMACS_INT) < sizeof (EMACS_INT).
14931 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
14933 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

14939 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
14940 supposed to be handshaking. (Bug#8556)
14941 Reported by Paul Eggert <eggert@cs.ucla.edu>.
14943 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
14945 * lisp.h (Qdebug): List symbol.
14946 * eval.c (Qdebug): Restore global linkage.

14948 (handle_user_signal): Break into debugger when debug-on-event
14949 matches the current signal symbol.
14951 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
14953 * alloc.c (check_sblock, check_string_bytes)
14954 (check_string_free_list): Convert to standard C.
14956 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
14958 * w32.c (emacs_gnutls_push): Fix typo.
14960 2011-04-25 Eli Zaretskii <eliz@gnu.org>
14962 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
14963 "cast to pointer from integer of different size".
14965 Improve doprnt and its use in verror. (Bug#8545)
14966 * doprnt.c (doprnt): Document the set of format control sequences
14967 supported by the function. Use SAFE_ALLOCA instead of always
14970 * eval.c (verror): Don't limit the buffer size at size_max-1, that
14971 is one byte too soon. Don't use xrealloc; instead xfree and
14974 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
14976 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
14979 * gnutls.c: Renamed global_initialized to
14980 gnutls_global_initialized. Added internals for the
14981 :verify-hostname-error, :verify-error, and :verify-flags
14982 parameters of `gnutls-boot' and documented those parameters in the
14983 docstring. Start callback support.
14984 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
14985 unless a fatal error occurred. Call gnutls_alert_send_appropriate
14986 on error. Return error code.
14987 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
14988 (emacs_gnutls_read): Likewise.
14989 (Fgnutls_boot): Return handshake error code.
14990 (emacs_gnutls_handle_error): New function.
14991 (wsaerror_to_errno): Likewise.

15046 changes in globals.h immediately force recompilation.
15047 (TAGS): Depend on $(CURDIR)/m/intel386.h and
15048 $(CURDIR)/s/ms-w32.h.

15053 <char-direction-table>: Deleted.
15055 2011-04-23 Eli Zaretskii <eliz@gnu.org>
15057 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
15058 * doprnt.c: Include limits.h.
15059 (SIZE_MAX): New macro.
15060 (doprnt): Return a size_t value. 2nd arg is now size_t.
15061 Many local variables are now size_t instead of int or unsigned.
15062 Improve overflow protection. Support `l' modifier for integer
15063 conversions. Support %l conversion. Don't assume an EMACS_INT
15064 argument for integer conversions and for %c.
15066 * lisp.h (doprnt): Restore prototype.
15068 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
15069 $(SRC)/character.h.
15071 * Makefile.in (base_obj): Add back doprnt.o.
15073 * deps.mk (doprnt.o): Add back prerequisites.
15074 (callint.o): Depend on character.h.
15076 * eval.c (internal_lisp_condition_case): Include the handler
15077 representation in the error message.
15078 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
15079 when breaking from the loop.

15083 * callint.c (Fcall_interactively): When displaying error message
15084 about invalid control letter, pass the character's codepoint, not
15085 a pointer to its multibyte form. Improve display of the character
15086 in octal and display also its hex code.
15088 * character.c (char_string): Use %x to display the (unsigned)
15089 codepoint of an invalid character, to avoid displaying a bogus
15092 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15093 `error', not SYMBOL_NAME itself.
15095 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
15096 character arguments to `error'.
15098 * charset.c (check_iso_charset_parameter): Fix incorrect argument
15099 to `error' in error message about FINAL_CHAR argument. Make sure
15100 FINAL_CHAR is a character, and use %c when it is passed as
15101 argument to `error'.

15119 zombies (Bug#8467).
15121 2011-04-19 Eli Zaretskii <eliz@gnu.org>
15123 * syntax.h (SETUP_SYNTAX_TABLE_FOR_OBJECT): Fix setting of

15165 Define only if needed.
15167 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
15168 by pacifying GCC about it. Maybe it's time to retire it?
15169 * xfaces.c (USG, __TIMEVAL__): Likewise.
15171 * dispextern.h (struct redisplay_interface): Rename param
15172 to avoid shadowing.
15173 * termhooks.h (struct terminal): Likewise.
15174 * xterm.c (xembed_send_message): Likewise.
15176 * insdel.c (make_gap_smaller): Define only if
15177 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
15179 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
15182 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
15183 so that we aren't warned about unused symbols.
15185 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
15187 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
15189 * xfns.c (x_real_positions): Mark locals as initialized.
15191 * xmenu.c (xmenu_show): Don't use uninitialized vars.
15193 * xterm.c: Fix problems found by static analysis with other toolkits.
15194 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
15195 (x_dispatch_event): Declare static if USE_GTK, and
15196 define if USE_GTK || USE_X_TOOLKIT.
15197 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
15198 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
15199 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
15200 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
15202 * xmenu.c (menu_help_callback): Pointer type fixes.
15203 Use const pointers when pointing at readonly data. Avoid pointer
15204 signedness clashes.

15206 (update_frame_menubar): Remove unused decl.
15208 * xfns.c (Fx_hide_tip): Move locals to avoid shadowing.

15290 * nsfont.m: Fixed bugs in ns_get_family and
15291 ns_descriptor_to_entity that were caused by using free to
15292 deallocate memory blocks that were allocated by xmalloc (via
15293 xstrdup). This caused Emacs to crash when compiled with
15294 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
15295 --enable-checking=xmallocoverrun). xfree is now used to
15296 deallocate these memory blocks.

15658 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
15659 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
15660 was inaccessible from Lisp.
15661 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
15662 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
15664 alloc.c: Import and export fewer symbols, and remove unused items.
15665 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
15667 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
15668 it's not optimized away by whole-program optimization.
15669 (message_enable_multibyte, free_misc): Remove.
15670 (catchlist, handlerlist, mark_backtrace):
15671 Declare only if BYTE_MARK_STACK.
15672 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
15673 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
15674 (message_enable_multibyte): Remove decl.
15675 (free_misc, interval_free_list, float_block, float_block_index):
15676 (n_float_blocks, float_free_list, cons_block, cons_block_index):
15677 (cons_free_list, last_marked_index):
15679 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
15680 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
15681 (mark_backtrace): Define only if BYTE_MARK_STACK.
15682 * xdisp.c (message_enable_multibyte): Now static.
15684 Declare Lisp_Object Q* variables to be 'static' if not exported.
15685 This makes it easier for human readers (and static analyzers)
15686 to see whether these variables are used from other modules.
15687 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
15688 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
15689 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
15690 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
15691 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
15692 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
15693 * xmenu.c, xselect.c:
15694 Declare Q* vars static if they are not used in other modules.
15695 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
15696 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
15697 Remove decls of unexported vars.
15698 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
15700 * lisp.h (DEFINE_FUNC): Make sname 'static'.
15702 Make Emacs functions such as Fatom 'static' by default.
15703 This makes it easier for human readers (and static analyzers)
15704 to see whether these functions can be called from other modules.
15705 DEFUN now defines a static function. To make the function external
15706 so that it can be used in other C modules, use the new macro DEFUE.
15707 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
15708 (Finit_image_library):
15709 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
15710 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
15711 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
15712 Remove decls, since these functions are now static.
15713 (Funintern, Fget_internal_run_time): New decls, since these functions
15714 were already external.
15716 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
15717 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
15718 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
15719 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
15720 * keyboard.c, keymap.c, lread.c:
15721 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
15722 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
15723 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
15724 Mark functions with DEFUE instead of DEFUN,
15725 if they are used in other modules.
15726 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
15727 decls for now-static functions.
15728 * buffer.h (Fdelete_overlay): Remove decl.
15729 * callproc.c (Fgetenv_internal): Mark as internal.
15730 * composite.c (Fremove_list_of_text_properties): Remove decl.

15733 * dired.c (Ffile_attributes): New forward static decl.
15734 * doc.c (Fdocumntation_property): New forward static decl.
15735 * eval.c (Ffetch_bytecode): New forward static decl.
15736 (Funintern): Remove extern decl; now in .h file where it belongs.
15737 * fileio.c (Fmake_symbolic_link): New forward static decl.
15738 * image.c (Finit_image_library): New forward static decl.
15739 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
15740 * intervals.h (Fprevious_property_change):
15741 (Fremove_list_of_text_properties): Remove decls.
15742 * keyboard.c (Fthis_command_keys): Remove decl.
15743 (Fcommand_execute): New forward static decl.
15744 * keymap.c (Flookup_key): New forward static decl.
15745 (Fcopy_keymap): Now static.
15746 * keymap.h (Flookup_key): Remove decl.
15747 * process.c (Fget_process): New forward static decl.
15748 (Fprocess_datagram_address): Mark as internal.
15749 * syntax.c (Fsyntax_table_p): New forward static decl.
15750 (skip_chars): Remove duplicate decl.
15751 * textprop.c (Fprevious_property_change): New forward static decl.
15752 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
15754 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
15755 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
15757 * editfns.c (Fformat): Remove unreachable code.
15759 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
15761 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
15764 2011-04-13 Eli Zaretskii <eliz@gnu.org>
15766 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
15767 when at ZV. (Bug#8487)
15769 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
15771 * charset.c (Fclear_charset_maps): Use xfree instead of free.
15773 * keyboard.c (parse_tool_bar_item): Likewise.
15774 * sound.c (sound_cleanup, alsa_close): Likewise.
15775 * termcap.c (tgetent): Likewise.
15776 * xfns.c (x_default_font_parameter): Likewise.
15777 * xsettings.c (read_and_apply_settings): Likewise.
15779 * alloc.c (overrun_check_malloc, overrun_check_realloc)
15780 (overrun_check_free): Protoize.
15782 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
15784 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
15785 since callers should never pass a negative size.
15786 Change the signature to match that of plain 'read' and 'write'; see
15787 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
15788 * lisp.h: Update prototypes of emacs_write and emacs_read.
15790 2011-04-11 Eli Zaretskii <eliz@gnu.org>
15792 * xdisp.c (redisplay_window): Don't try to determine the character
15793 position of the scroll margin if the window start point w->startp
15794 is outside the buffer's accessible region. (Bug#8468)
15796 2011-04-10 Eli Zaretskii <eliz@gnu.org>
15798 Fix write-region and its subroutines for buffers > 2GB.
15799 * fileio.c (a_write, e_write): Modify declaration of arguments and
15800 local variables to support buffers larger than 2GB.
15801 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
15803 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
15804 argument, local variables, and return value.
15806 * lisp.h: Update prototypes of emacs_write and emacs_read.
15808 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
15810 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
15812 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
15814 Fix more problems found by GCC 4.6.0's static checks.
15816 * xdisp.c (vmessage): Use a better test for character truncation.
15818 * charset.c (load_charset_map): <, not <=, for optimization,
15819 and to avoid potential problems with integer overflow.
15820 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
15821 * casetab.c (set_identity, shuffle): Likewise.
15822 * editfns.c (Fformat): Likewise.
15823 * syntax.c (skip_chars): Likewise.
15825 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
15826 This also lets GCC 4.6.0 generate slightly better loop code.
15828 * callint.c (Fcall_interactively): <, not <=, for optimization.
15829 (Fcall_interactively): Count the number of arguments produced,
15830 not the number of arguments given. This is simpler and lets GCC
15831 4.6.0 generate slightly better code.
15833 * ftfont.c: Distingish more carefully between FcChar8 and char.
15834 The previous code passed unsigned char * to a functions like
15835 strlen and xstrcasecmp that expect char *, which does not
15836 conform to the C standard.
15837 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
15838 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
15839 char * when the C standard requires it.
15841 * keyboard.c (read_char): Remove unused var.
15843 * eval.c: Port to Windows vsnprintf (Bug#8435).
15844 Include <limits.h>.
15845 (SIZE_MAX): Define if the headers do not.
15846 (verror): Do not give up if vsnprintf returns a negative count.
15847 Instead, grow the buffer. This ports to Windows vsnprintf, which
15848 does not conform to C99. Problem reported by Eli Zaretskii.
15849 Also, simplify the allocation scheme, by avoiding the need for
15850 calling realloc, and removing the ALLOCATED variable.
15852 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
15854 Remove invocations of doprnt, as Emacs now uses vsnprintf.
15855 But keep the doprint source code for now, as we might revamp it
15856 and use it again (Bug#8435).
15857 * lisp.h (doprnt): Remove.
15858 * Makefile.in (base_obj): Remove doprnt.o.
15859 * deps.mk (doprnt.o): Remove.
15861 error: Print 32- and 64-bit integers portably (Bug#8435).
15862 Without this change, on typical 64-bit hosts error ("...%d...", N)
15863 was used to print both 32- and 64-bit integers N, which relied on
15864 undefined behavior.
15865 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
15866 * lisp.h (error, verror): Mark as printf-like functions.
15867 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
15868 Report overflow in size calculations when allocating printf buffer.
15869 Do not truncate output string at its first null byte.
15870 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
15871 Truncate the output at a character boundary, since vsnprintf does not
15873 * charset.c (check_iso_charset_parameter): Convert internal
15874 character to string before calling 'error', since %c now has the
15876 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
15877 overflow when computing char to be passed to 'error'. Do not
15878 pass Lisp_Object to 'error'; pass the integer instead.
15879 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
15880 formatted with plain %d.
15882 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
15884 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
15886 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
15888 * xterm.c (x_catch_errors): Remove duplicate declaration.
15890 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
15892 * xdisp.c, lisp.h (message_nolog): Remove; unused.
15894 2011-04-10 Jim Meyering <meyering@redhat.com>
15896 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
15897 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
15898 return ssize_t not "int", and use size_t as the buffer length.
15899 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
15900 * gnutls.h: Update declarations.
15901 * process.c (read_process_output): Use ssize_t, to match.
15902 (send_process): Likewise.
15904 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15906 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
15908 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15910 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
15911 Use unsigned char, to match FcChar8 type definition.
15913 * xterm.c (handle_one_xevent):
15914 * xmenu.c (create_and_show_popup_menu):
15915 * xselect.c (x_decline_selection_request)
15916 (x_reply_selection_request): Avoid type-punned deref of X events.
15918 2011-04-09 Eli Zaretskii <eliz@gnu.org>
15920 Fix some uses of `int' instead of EMACS_INT.
15921 * search.c (string_match_1, fast_string_match)
15922 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
15923 (scan_buffer, find_next_newline_no_quit)
15924 (find_before_next_newline, search_command, Freplace_match)
15925 (Fmatch_data): Make some `int' variables be EMACS_INT.
15927 * xdisp.c (display_count_lines): 3rd argument and return value now
15928 EMACS_INT. All callers changed.
15929 (pint2hrstr): Last argument is now EMACS_INT.
15931 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
15932 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
15933 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
15934 (decode_coding_utf_16, decode_coding_emacs_mule)
15935 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
15936 (decode_coding_ccl, decode_coding_charset)
15937 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
15938 (decode_coding_iso_2022, decode_coding_emacs_mule)
15939 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
15940 <char_offset, last_offset>: Declare EMACS_INT.
15941 (encode_coding_utf_8, encode_coding_utf_16)
15942 (encode_coding_emacs_mule, encode_invocation_designation)
15943 (encode_designation_at_bol, encode_coding_iso_2022)
15944 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
15945 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
15947 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
15948 (encode_invocation_designation): Last argument P_NCHARS is now
15950 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
15951 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
15953 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
15956 * ccl.c (Fccl_execute_on_string): Declare some variables
15959 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
15961 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
15963 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
15965 * process.c (Fformat_network_address): Doc fix.
15967 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
15969 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
15971 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
15973 * keyboard.c (read_char): Call Lisp function help-form-show,
15974 instead of using internal_with_output_to_temp_buffer.
15975 (Qhelp_form_show): New var.
15976 (syms_of_keyboard): Use DEFSYM macro.
15978 * print.c (internal_with_output_to_temp_buffer): Function deleted.
15980 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
15982 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
15984 * process.c (Flist_processes): Remove to Lisp.
15985 (list_processes_1): Delete.
15987 2011-04-06 Eli Zaretskii <eliz@gnu.org>
15989 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
15991 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
15993 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
15995 Fix more problems found by GCC 4.6.0's static checks.
15997 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
15999 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
16001 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
16003 * xdisp.c (vmessage): Mark as a printf-like function.
16005 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
16007 * sound.c (sound_warning): Don't crash if arg contains a printf format.
16009 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
16010 printf-like functions.
16011 (tiff_load): Add casts to remove these marks before passing them
16012 to system-supplied API.
16014 * eval.c (Fsignal): Remove excess argument to 'fatal'.
16016 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
16017 This avoids several warnings with gcc -Wstrict-overflow.
16018 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
16019 directly, rather than having caller test rule sign. This avoids
16020 some unnecessary tests.
16021 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
16022 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
16023 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
16025 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16026 (xfont_open): Avoid unnecessary tests.
16028 * composite.c (composition_gstring_put_cache): Use unsigned integer.
16030 * composite.h, composite.c (composition_gstring_put_cache):
16031 Use EMACS_INT, not int, for length.
16033 * composite.h (COMPOSITION_DECODE_REFS): New macro,
16034 breaking out part of COMPOSITION_DECODE_RULE.
16035 (COMPOSITION_DECODE_RULE): Use it.
16036 * composite.c (get_composition_id): Remove unused local vars,
16037 by using the new macro.
16039 * textprop.c (set_text_properties_1): Change while to do-while,
16040 since the condition is always true at first.
16042 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16043 (interval_deletion_adjustment): Return unsigned value.
16046 * process.c (list_processes_1, create_pty, read_process_output):
16047 (exec_sentinel): Remove vars that were set but not used.
16048 (create_pty): Remove unnecessary "volatile"s.
16049 (Fnetwork_interface_info): Avoid possibility of int overflow.
16050 (read_process_output): Do adaptive read buffering even if carryover.
16051 (read_process_output): Simplify nbytes computation if buffered.
16053 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
16055 * syntax.c (scan_words): Remove var that was set but not used.
16056 (update_syntax_table): Use unsigned instead of int.
16058 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
16059 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
16060 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
16062 * print.c (print_error_message): Avoid int overflow.
16064 * font.c (font_list_entities): Redo for clarity,
16065 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
16067 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
16068 (font_score): Avoid potential overflow in diff calculation.
16070 * fns.c (substring_both): Remove var that is set but not used.
16071 (sxhash): Redo loop for clarity and to avoid wraparound warning.
16073 * eval.c (funcall_lambda): Rename local to avoid shadowing.
16075 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
16076 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
16077 can always succeed if overflow has undefined behavior.
16079 * search.c (boyer_moore, wordify): Remove vars set but not used.
16080 (wordify): Omit three unnecessary tests.
16082 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
16083 All callers changed. This avoids the need for an unused var.

16095 Check for integer overflow on size calculations.
16097 * buffer.c (Fprevious_overlay_change): Remove var that is set
16100 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16101 Remove vars that are set but not used.
16102 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16103 (timer_check_2): Mark vars as initialized.

16107 * image.c (lookup_image): Remove var that is set but not used.
16108 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16110 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16111 that are set but not used.
16113 * xfns.c (make_invisible_cursor): Don't return garbage
16114 if XCreateBitmapFromData fails (Bug#8410).
16116 * xselect.c (x_get_local_selection, x_handle_property_notify):
16117 Remove vars that are set but not used.
16119 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

16125 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16126 Check for overflow.
16128 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16129 (map_tty_color) [!defined MSDOS]: Likewise.
16131 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16133 * coding.c: Remove vars that are set but not used.
16134 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

16143 * print.c (print_object): Remove var that is set but not used.
16145 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16146 The gnulib version avoids calling malloc in the usual case,
16147 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16148 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16149 * filelock.c (current_lock_owner): Likewise.
16150 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16151 * sysdep.c: Include allocator.h, careadlinkat.h.
16152 (emacs_no_realloc_allocator): New static constant.
16153 (emacs_readlink): New function.
16154 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16155 ../lib/careadlinkat.h.
16157 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
16159 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

16181 do not dereference NULL upon failed strdup
16182 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16183 (ns_get_family): Likewise.
16185 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16187 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16189 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16191 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16194 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16196 Add lexical binding.

16207 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16209 (syms_of_lread): Declare `lexical-binding'.
16211 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16213 * keyboard.c (eval_dyn): New fun.
16214 (menu_item_eval_property): Use it.
16216 * image.c (parse_image_spec): Use Ffunctionp.
16218 * fns.c (concat, mapcar1): Accept byte-code-functions.
16220 * eval.c (Fsetq): Handle lexical vars.
16221 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16222 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16223 (FletX, Flet): Obey lexical binding.
16224 (Fcommandp): Handle closures.
16225 (Feval): New `lexical' arg.
16226 (eval_sub): New function extracted from Feval. Use it almost
16227 everywhere where Feval was used. Look up vars in lexical env.
16229 (Ffunctionp): Move from subr.el.
16230 (Ffuncall): Handle closures.
16231 (apply_lambda): Remove `eval_flags'.
16232 (funcall_lambda): Handle closures and new byte-code-functions.
16233 (Fspecial_variable_p): New function.
16234 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16235 but without exporting it to Lisp.
16237 * doc.c (Fdocumentation, store_function_docstring):
16238 * data.c (Finteractive_form): Handle closures.
16240 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16243 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16245 (exec_byte_code): New function extracted from Fbyte_code to handle new
16246 calling convention for byte-code-functions. Add new byte-codes.
16248 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
16250 * alloc.c (Fmake_symbol): Init new `declared_special' field.

16254 * xdisp.c (redisplay_internal): Fix prototype.
16256 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16258 * xdisp.c (SCROLL_LIMIT): New macro.
16259 (try_scrolling): Use it when setting scroll_limit.
16260 Limit scrolling to 100 screen lines.
16261 (redisplay_window): Even when falling back on "recentering",
16262 position point in the window according to scroll-conservatively,
16263 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16265 (try_scrolling): When point is above the window, allow searching
16266 as far as scroll_max, or one screenful, to compute vertical
16267 distance from PT to the scroll margin position. This prevents
16268 try_scrolling from unnecessarily failing when
16269 scroll-conservatively is set to a value slightly larger than the
16270 window height. Clean up the case of PT below the margin at bottom
16271 of window: scroll_max can no longer be INT_MAX. When aggressive
16272 scrolling is in use, don't let point enter the opposite scroll
16273 margin as result of the scroll.
16274 (syms_of_xdisp) <scroll-conservatively>: Document the
16275 threshold of 100 lines for never-recentering scrolling.

16282 (message_log_check_duplicate): Remove parameters `prev_bol' and
16283 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16284 (redisplay_internal): Remove parameter `preserve_echo_area',
16285 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16287 * indent.c (Fvertical_motion):
16288 * window.c (window_scroll_pixel_based, Frecenter):
16289 Don't pass `need_y_p' to `move_it_by_lines'.
16291 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16293 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16294 steal a few bits to be more compact.
16295 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16296 Remove unneeded casts.
16298 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16300 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16302 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16303 binding" message (bug#7967).
16305 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16307 Fix more problems found by GCC 4.6.0's static checks.
16309 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16310 Remove unused local var.
16312 * editfns.c (Fmessage_box): Remove unused local var.
16314 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16315 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16316 Omit unused local vars.
16317 * window.c (shrink_windows): Omit unused local var.
16318 * menu.c (digest_single_submenu): Omit unused local var.
16319 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16320 Omit unused local var.
16322 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16323 Don't assume string length fits in int.
16324 (keyremap_step, read_key_sequence): Use size_t for sizes.

16328 instead of alloca (Bug#8344).
16330 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16331 (Fbacktrace_frame): Don't assume nframes fits in int.
16333 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

16340 * cm.c (calccost): Turn while-do into do-while, for clarity.
16342 * keyboard.c (syms_of_keyboard): Use the same style as later
16343 in this function when indexing through an array. This also
16344 works around GCC bug 48267.
16346 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16348 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16350 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16351 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16353 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16354 This avoids undefined behavior on integer overflow, and is a bit
16355 more convenient anyway since it is compared to a size_t variable.
16357 Variadic C functions now count arguments with size_t, not int.
16358 This avoids an unnecessary limitation on 64-bit machines, which
16359 caused (substring ...) to crash on large vectors (Bug#8344).

16369 * fns.c (concat): Likewise.
16370 * frame.c (x_set_frame_parameters): Likewise.
16371 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16372 0 if not found, not -1. All callers changed.
16374 * alloc.c (garbage_collect): Don't assume stack size fits in int.
16375 (stack_copy_size): Now size_t, not int.
16376 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
16378 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
16380 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
16381 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

16401 Vcommand_hook_internal.

16542 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
16544 * w32term.c (x_set_glyph_string_clipping):
16545 Don't pass uninitialized region to CombineRgn.

16569 2011-03-23 Julien Danjou <julien@danjou.info>
16571 * term.c (Fsuspend_tty, Fresume_tty):
16572 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
16573 * window.c (temp_output_buffer_show):
16574 * insdel.c (signal_before_change):
16575 * frame.c (Fhandle_switch_frame):

16580 * callint.c (Fcall_interactively):
16581 * buffer.c (Fkill_all_local_variables):
16582 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
16584 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
16585 unconditionally since it does the check itself.
16587 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
16589 Fix more problems found by GCC 4.5.2's static checks.
16591 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16592 the first time through the loop, since we know p0 < p1 then.
16593 This also avoids a gcc -Wstrict-overflow warning.
16595 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16596 leading to a memory leak, possible in functions like
16597 load_charset_map_from_file that can allocate an unbounded number
16598 of objects (Bug#8318).
16600 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16601 that could (at least in theory) be that large.
16603 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16604 This is less likely to overflow, and avoids undefined behavior if
16605 overflow does occur. All callers changed. Use strtoul to scan
16606 for the unsigned long integer.
16607 (pint2hrstr): Simplify and tune code slightly.
16608 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
16610 * scroll.c (do_scrolling): Work around GCC bug 48228.
16611 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
16613 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
16614 This also avoids a warning with gcc -Wstrict-overflow.

16616 This also avoids a warning with gcc -Wstrict-overflow.
16618 * fileio.c (Fcopy_file): Report error if fchown or fchmod
16621 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
16623 * process.c (Fmake_network_process): Use socklen_t, not int,
16624 where POSIX says socklen_t is required in portable programs.
16625 This fixes a porting bug on hosts like 64-bit HP-UX, where
16626 socklen_t is wider than int (Bug#8277).
16627 (Fmake_network_process, server_accept_connection):
16628 (wait_reading_process_output, read_process_output):
16631 * process.c: Rename or move locals to avoid shadowing.

16641 Make tparam.h and terminfo.c consistent.
16642 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
16643 Include tparam.h instead, since it declares them.
16644 * cm.h (PC): Remove extern decl; tparam.h now does this.
16645 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
16646 * terminfo.c: Include tparam.h, to check interfaces.
16647 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
16648 (tparam): Adjust signature to match interface in tparam.h;
16649 this removes some undefined behavior. Check that outstring and len
16650 are zero, which they always are with Emacs.
16651 * tparam.h (PC, BC, UP): New extern decls.
16653 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
16654 (xftfont_open): Rename locals to avoid shadowing.
16656 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
16657 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
16658 (OTF_TAG_SYM): Omit macro if not needed.

16666 * xml.c (make_dom): Now static.
16668 * composite.c (composition_compute_stop_pos): Rename local to
16670 (composition_reseat_it): Remove unused locals.
16671 (find_automatic_composition, composition_adjust_point): Likewise.
16672 (composition_update_it): Mark var as initialized.
16673 (find_automatic_composition): Mark vars as initialized,
16674 with a FIXME (Bug#8290).

16677 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
16678 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
16679 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
16680 (BUF_DEC_POS): Be more systematic about renaming local temporaries
16681 to avoid shadowing.
16683 * textprop.c (property_change_between_p): Remove; unused.
16685 * intervals.c (interval_start_pos): Now static.
16687 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

16690 Rename locals to avoid shadowing.
16692 * sound.c (wav_play, au_play, Fplay_sound_internal):
16693 Fix pointer signedness.
16694 (alsa_choose_format): Remove unused local var.
16695 (wav_play): Initialize a variable to 0, to prevent undefined
16696 behavior (Bug#8278).
16698 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
16700 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
16702 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
16703 clobbering (Bug#8298).
16704 * sysdep.c (sys_subshell): Likewise.
16705 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
16707 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
16708 This should get cleaned up, so that child_setup has the
16709 same signature on all platforms.
16711 * callproc.c (call_process_cleanup): Now static.
16712 (relocate_fd): Rename locals to avoid shadowing.
16714 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
16716 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
16717 not to be necessary, and produces flickering.
16719 2011-03-20 Glenn Morris <rgm@gnu.org>
16721 * config.in: Remove file.
16723 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
16725 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
16726 are now in src/globals.h.
16727 (syms_of_minibuf): Remove spurious & from previous change.
16729 2011-03-20 Leo Liu <sdl.web@gmail.com>
16731 * minibuf.c (completing-read-function): New variable.
16732 (completing-read-default): Rename from completing-read.
16733 (completing-read): Call completing-read-function.
16735 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16737 * xfaces.c (Fx_load_color_file):
16738 Read color file from absolute filename (bug#8250).
16740 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16742 * makefile.w32-in: Update dependencies.
16744 2011-03-17 Eli Zaretskii <eliz@gnu.org>
16746 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

16753 (sigchld_handler): Now static.
16755 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
16756 That way, the code declares only the vars that it needs.
16757 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
16758 * s/cygwin.h (PTY_ITERATION): Likewise.
16759 * s/darwin.h (PTY_ITERATION): Likewise.

16766 (CONSTANTLIM): Remove; unused.
16767 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
16768 Define only if needed.
16770 * unexelf.c (unexec): Name an expression,
16771 to avoid gcc -Wbad-function-cast warning.
16772 Use a different way to cause a compilation error if anyone uses
16773 n rather than nn, a way that does not involve shadowing.
16774 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
16776 * deps.mk (unexalpha.o): Remove; unused.
16778 New file unexec.h, the (simple) interface for unexec (Bug#8267).
16779 * unexec.h: New file.
16780 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
16781 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
16782 Depend on unexec.h.
16783 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
16784 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
16785 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
16786 Change as necessary to match prototype in unexec.h.
16788 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

16805 (font_sort_entities): Mark var as initialized.
16807 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
16809 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

16833 * callint.c (quotify_arg, quotify_args): Now static.
16834 (Fcall_interactively): Rename locals to avoid shadowing.
16835 Use const pointer when appropriate.

16841 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
16842 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
16843 some of which prompt warnings from gcc -Wbad-function-cast.
16844 (Fformat_time_string, Fencode_time, Finsert_char):
16845 (Ftranslate_region_internal, Fformat):
16846 Rename or remove local vars to avoid shadowing.
16847 (Ftranslate_region_internal): Mark var as initialized.
16849 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
16852 * lisp.h (eassert): Check that the argument compiles, even if
16853 ENABLE_CHECKING is not defined.
16855 * data.c (Findirect_variable): Name an expression, to avoid
16856 gcc -Wbad-function-cast warning.

16865 Rename locals to avoid shadowing.
16866 (mark_stack): Move local variables into the #ifdef region where
16868 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
16869 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
16871 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
16872 (GC_STRING_CHARS): Remove; not used.
16873 (Fmemory_limit): Cast sbrk's returned value to char *.
16875 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
16876 avoids undefined behavior in theory.

16881 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16882 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
16883 to use the following functions instead of these macros.
16884 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
16885 EMACS_INT, since callers assume the returned value fits in int.
16886 (upcase1): Likewise, for UPCASE_TABLE.
16887 (uppercasep, lowercasep, upcase): New static inline functions.
16888 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
16889 the race-condition problem in the old DOWNCASE.

16893 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
16894 (regex_compile, re_search_2, re_match_2_internal):
16895 Remove unused local vars.
16896 (FREE_VAR): Rewrite so as not to use empty "else",
16897 which gcc can warn about.
16898 (regex_compile, re_match_2_internal): Mark locals as initialized.
16899 (RETALLOC_IF): Define only if needed.
16900 (WORDCHAR_P): Likewise. This one is never needed, but is used
16901 only in a comment talking about a compiler bug, so put inside
16902 the #if 0 of that comment.
16903 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
16904 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
16907 * search.c (boyer_moore): Rename locals to avoid shadowing.
16908 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
16909 (PREV_CHAR_BOUNDARY): Likewise.
16911 * search.c (simple_search): Remove unused var.
16913 * dired.c (compile_pattern): Move decl from here ...

16919 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
16921 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
16922 Rename locals to avoid shadowing.
16923 (Fvertical_motion): Mark locals as initialized.
16925 * casefiddle.c (casify_object, casify_region): Now static.
16926 (casify_region): Mark local as initialized.
16928 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
16930 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
16931 New macros, so that the caller can use some names other than
16932 gcpro1, gcpro2, etc.
16933 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
16935 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
16936 argument, for consistency with GCPRO2_VAR, etc: it is now the
16937 prefix of the variable, not the variable itself. All uses
16939 * dired.c (directory_files_internal, file_name_completion):
16940 Rename locals to avoid shadowing.
16942 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
16943 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
16944 dired.c's scmp function, had undefined behavior.
16945 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16946 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
16947 * buffer.h: ... to here, because these macros use current_buffer,
16948 and the new implementation with inline functions needs to have
16949 current_buffer in scope now, rather than later when the macros
16951 (downcase, upcase1): New static inline functions.
16952 (DOWNCASE, UPCASE1): Reimplement using these functions.
16953 This avoids undefined behavior in expressions like
16954 DOWNCASE (x) == DOWNCASE (y), which previously suffered
16955 from race conditions in accessing the global variables
16956 case_temp1 and case_temp2.
16957 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
16958 * lisp.h (case_temp1, case_temp2): Remove their decls.
16959 * character.h (ASCII_CHAR_P): Move from here ...
16960 * lisp.h: ... to here, so that the inline functions mentioned
16961 above can use them.
16963 * dired.c (directory_files_internal_unwind): Now static.
16965 * fileio.c (file_name_as_directory, directory_file_name):
16966 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
16968 (file_name_as_directory): Use const pointers when appropriate.
16969 (Fexpand_file_name): Likewise. In particular, newdir might
16970 point at constant storage, so make it a const pointer.
16971 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
16972 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer

17404 Move these decls to tparam.h, and make them agree with what
17405 is actually in tparam.c. The previous trick of using incompatible
17406 decls in different modules does not conform to the C standard.
