3 * image.c (define_image_type): Avoid adding duplicate types to
4 image_types (Bug#12463). Suggested by Jörg Walter.
6 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
8 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
9 (print_load_command_name): Add case LC_DATA_IN_CODE.
10 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
12 2012-09-21 Glenn Morris <rgm@gnu.org>
14 * eval.c (Frun_hook_with_args_until_success)
15 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
17 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
19 * fileio.c (Ffile_selinux_context): Only call freecon when
20 lgetfilecon succeeded.
21 (Fset_file_selinux_context): Likewise. (Bug#12444)
23 2012-09-21 Eli Zaretskii <eliz@gnu.org>
25 * xdisp.c (try_window_reusing_current_matrix): Under bidi
26 reordering, locate the cursor by calling set_cursor_from_row; if
27 that fails, clear the desired glyph matrix before returning a
28 failure indication to the caller. Fixes leaving garbled display
29 when fast scrolling with a down-key. (Bug#12403)
30 (compute_stop_pos_backwards): Fix a typo that caused crashes while
31 scrolling through multibyte text.
33 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
35 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
36 calling mark_vectorlike since that's the one that marks the window.
37 (mark_discard_killed_buffers): Mark the final cdr.
38 * window.h (struct window): Move prev/next_buffers to the
40 * window.c (make_window): Initialize prev/next_buffers manually.
42 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
44 Omit unused arg EXPECTED from socket hooks.
45 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
46 * nsterm.m (ns_term_init):
47 * termhooks.h (struct terminal.read_socket_hook):
48 * w32inevt.c (w32_console_read_socket):
49 * w32term.c (w32_read_socket):
50 * xterm.c (XTread_socket):
51 Omit unused arg EXPECTED. All callers changed.
52 (store_user_signal_events): Return void, not int, since callers no
53 longer care about the return value. All uses changed.
55 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
57 * w32gui.h (XParseGeometry): Do not declare.
59 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
61 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
62 Ignore 'expected'. See Eli Zaretskii in
63 <http://bugs.gnu.org/12471#8> (last line).
65 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
66 (XParseGeometry): Now static. Substitute extremal values for
67 values that are out of range.
69 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
71 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
73 * nsfns.m (XParseGeometry): Remove.
74 (Fx_create_frame): Call x_set_offset to correctly interpret
77 * frame.c (read_integer, XParseGeometry): Moved from w32xfns.c.
78 (Fx_parse_geometry): If there is a space in string, call
79 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
81 2012-09-17 Eli Zaretskii <eliz@gnu.org>
83 * search.c (scan_buffer): Use character positions in calls to
84 region_cache_forward and region_cache_backward, not byte
85 positions. (Bug#12196)
87 * w32term.c (w32_read_socket): Set pending_signals to 1, like
88 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
90 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
91 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
92 emacs_blocked_malloc, now deleted.
94 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
96 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
97 The workaround was for improving performance on Solaris 2.4, but
98 is getting in the way now. Emacs will still work if someone is
99 still running Solaris 2.4 in a museum somewhere; Sun dropped
100 support for Solaris 2.4 in 2003.
101 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
102 * process.c (create_process) [HAVE_WORKING_VFORK]:
103 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
104 since Emacs no longer uses vfork on that platform.
106 2012-09-17 Glenn Morris <rgm@gnu.org>
108 * emacs.c: Use COPYRIGHT.
110 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
112 Remove configure's --without-sync-input option (Bug#12450).
113 When auditing signal-handling in preparation for cleaning it up,
114 I found that SYNC_INPUT has race conditions and would be a real
115 pain to fix. Since it's an undocumented and deprecated
116 configure-time option, now seems like a good time to remove it.
117 Also see <http://bugs.gnu.org/11080#16>.
118 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
119 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
120 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
122 (check_depth) [XMALLOC_OVERRUN_CHECK]:
123 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
124 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
125 (dont_register_blocks, bytes_used_when_reconsidered)
126 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
127 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
128 [!SYSTEM_MALLOC && !SYNC_INPUT]:
129 Remove. All uses removed.
130 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
131 implementation, one that depends on whether the new macro
132 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
134 * atimer.c (run_timers, handle_alarm_signal):
135 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
136 (handle_async_input, process_pending_signals)
137 (handle_input_available_signal, init_keyboard):
138 * nsterm.m (ns_read_socket):
139 * process.c (wait_reading_process_output):
140 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
141 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
143 * xterm.c (XTread_socket):
145 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
146 * eval.c (handling_signal): Remove. All uses removed.
147 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
148 All uses replaced with the SYNC_INPUT version.
149 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
151 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
154 * font.c (Ffont_shape_gstring): Remove unused local.
156 2012-09-16 Glenn Morris <rgm@gnu.org>
158 * Makefile.in (clean): No longer run nextstep's clean.
160 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
162 (ns-app): Move here from ns.mk, and simplify.
163 (clean): Simplify nextstep entry.
164 * ns.mk: Remove file.
166 2012-09-16 Kenichi Handa <handa@gnu.org>
168 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
169 not covert the last few charactes.
171 2012-09-16 Kenichi Handa <handa@gnu.org>
173 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
174 here, but just check the validity of glyphs in the glyph-string.
176 2012-09-16 Martin Rudalics <rudalics@gmx.at>
178 * window.c (Fwindow_parameter, Fset_window_parameter): Accept
179 any window as argument (Bug#12452).
181 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
183 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
184 to ns_term_init to avoid memory leak.
186 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
187 explicit retain/release.
188 (ns_term_init): Only allow one display. Initialize outerpool and
191 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
193 Port _setjmp fix to POSIXish hosts as well as Microsoft.
194 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
195 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
196 the Microsoft problem in a different way, by altering ../nt/config.nt.
198 2012-09-15 Eli Zaretskii <eliz@gnu.org>
213 * w16select.c: Remove inclusion of setjmp.h, as it is now included
214 by lisp.h. This completes removal of setjmp.h inclusion
215 erroneously announced in the previous commit. (Bug#12446)
217 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
220 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
221 not defined as a macro. The latter happens on MS-Windows.
224 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
226 Port better to POSIX hosts lacking _setjmp (Bug#12446).
227 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
228 Some instances of '#include <setjmp.h>' removed, if the
229 only reason for the instance was because "lisp.h" was included.
230 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
231 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
232 and _longjmp with the new symbols. Emacs already uses _setjmp if
233 available, so this change affects only POSIXish hosts that have
234 sigsetjmp but not _setjmp, such as some versions of Solaris and
235 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
236 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
237 (png_load_body) [HAVE_PNG]:
238 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
239 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
240 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
241 since PNG requires jmp_buf. This is the only exception to the
242 general rule that we now use sys_setjmp and sys_longjmp.
243 This exception is OK since this code does not change the signal
244 mask or longjmp out of a signal handler.
246 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
248 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
249 Include "syssignal.h", for 'main_thread'.
251 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
253 Avoid out-of-range marker position (Bug#12426).
254 * insdel.c (replace_range, replace_range_2): Adjust
255 markers before overlays, as suggested by comments.
256 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
257 Remove redundant check before calling offset_intervals.
259 2012-09-14 Martin Rudalics <rudalics@gmx.at>
261 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
262 current buffer (Bug#12387).
264 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
266 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
268 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
270 Use a more backwards-compatible timer format (Bug#12430).
271 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
272 vector element, not from the 4th, since PSECS is now at the end.
273 (Fcurrent_idle_time): Doc fix.
275 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
277 Function to mark objects and remove killed buffers at once.
278 * alloc.c (discard_killed_buffers): Rename to ...
279 (mark_discard_killed buffers) ... new name. Add marking
280 of remaining objects. Fix comment. Adjust users.
281 (mark_object): Do not touch frame buffer lists here.
282 * frame.c (delete_frame): Reset frame buffer lists here.
284 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
286 Better workaround for GNOME bug when --enable-gcc-warnings.
287 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
288 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
289 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
291 Simplify SIGIO usage (Bug#12408).
292 The code that dealt with SIGIO was crufty and confusing, e.g., it
293 played tricks like "#undef SIGIO" but these tricks were not used
294 consistently. Simplify mostly by not #undeffing standard symbols,
295 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
296 or not as we please) rather than "defined SIGIO" (standard symbol
297 that we probably shouldn't #undef).
298 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
299 Modules that need it can include it.
300 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
301 * dispextern.h (ignore_sigio): New decl.
302 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
303 unconditionally, since it's now a no-op if !USABLE_SIGIO.
304 * emacs.c (shut_down_emacs):
305 * keyboard.c (kbd_buffer_store_event_hold):
306 Use ignore_sigio rather than invoking 'signal' directly.
307 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
309 (FIONREAD, SIGIO): Do not #undef.
310 (tty_read_avail_input): Use #error rather than a syntax error.
311 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
312 for I_PIPE, used by SETUP_SLAVE_PTY.
313 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
314 * sysdep.c (croak): Remove; no longer needed. This bit of
315 temporary code, with Fred N. Fish's comment that it's temporary,
316 has been in Emacs since at least 1992!
317 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
318 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
319 * syssignal.h (croak): Remove decl.
320 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
321 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
322 now that we're termios-only.
323 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
324 * term.c (dissociate_if_controlling_tty): Use #error rather than
327 Work around GCC and GNOME bugs when --enable-gcc-warnings.
328 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
329 to work around GNOME bug 683906.
330 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
331 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
332 This works around GCC bug 54561.
334 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
336 More fixes for 'volatile' and setjmp/longjmp.
337 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
338 * image.c (struct png_load_context) [HAVE_PNG]: New type.
339 (png_load_body) [HAVE_PNG]:
340 (jpeg_load_body) [HAVE_JPEG]:
341 New function, with most of the old parent function's body.
342 (png_load) [HAVE_PNG]:
343 (jpeg_load) [HAVE_JPEG]:
344 Invoke the new function, to avoid longjmp munging our locals.
345 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
346 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
347 longjmp is passed 2, as the C standard doesn't guarantee this.
348 Instead, store the failure code into mgr->failure_code.
350 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
352 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
353 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
354 (syms_of_keyboard): Remove support for unread-command-char.
356 2012-09-12 Eli Zaretskii <eliz@gnu.org>
358 * w32proc.c (sys_kill): If PID is our process ID and the signal is
359 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
360 violation. (Bug#12426)
362 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
364 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
366 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
368 * eval.c: Add `inhibit-debugger'.
369 (Qinhibit_debugger): New symbol.
370 (call_debugger): Bind it instead of Qdebug_on_error.
371 (maybe_call_debugger): Test Vinhibit_debugger.
372 (syms_of_eval): Define inhibit-debugger.
373 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
374 (syms_of_xdisp): Remove inhibit-debug-on-message.
376 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
378 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
379 If a nonvolatile local variable is written before a _longjmp to
380 the frame containing the variable, and is read after the _longjmp,
381 the value read is indeterminate. Some local variables of type
382 'struct handler' and 'struct catchtag' are used in this way, so
383 mark each of their slots as volatile if the slot can be set before
384 _longjmp and read afterwards.
385 * lisp.h (struct handler): var and chosen_clause are now volatile.
386 (struct catchtag): val, next, and pdlcount are now volatile.
388 * bidi.c (bidi_push_it, bidi_pop_it):
389 * fns.c (copy_hash_table):
390 * image.c (define_image_type):
391 * keyboard.c (kbd_buffer_store_event_hold):
392 * process.c (Fprocess_send_eof):
393 * xfaces.c (x_create_gc) [HAVE_NS]:
394 * xgselect.c (xg_select):
395 Prefer assignment to memcpy when either will do.
397 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
398 Use pointer-to-a-pointer to simplify and avoid a NILP check each
399 time an item is removed. No need to mark this function 'inline';
400 the compiler knows better than we do.
402 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
404 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
405 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
406 to change_frame_size (Bug#12388).
407 (windowDidResize:): Pass YES to updateFrameSize.
409 * nsterm.h: Add delay parameter to updateFrameSize.
411 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
413 Discard killed buffers from deleted window and frame objects.
414 This reduces an amount of references to killed buffers and
415 helps GC to reclaim them faster.
416 * alloc.c (discard_killed_buffers): New function.
417 (mark_object): Use it for deleted windows and frames.
418 (mark_object): If symbol's value is set up for a killed buffer
419 or deleted frame, restore it's global binding.
420 * data.c (swap_in_global_binding): Add GC notice.
421 (swap_in_symval_forwarding): Use convenient set_blv_where.
422 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
423 * window.h: ... to here.
425 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
427 Convenient macro to check whether the buffer is live.
428 * buffer.h (BUFFER_LIVE_P): New macro.
429 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
430 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
432 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
434 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
435 composition cases (Bug#12364).
437 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
438 overhang of succeeding glyphs overlapping box cursor.
440 * w32term.c (x_draw_glyph_string): Likewise.
442 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
444 Simplify, document, and port floating-point (Bug#12381).
445 The porting part of this patch fixes bugs on non-IEEE platforms
446 with frexp, ldexp, logb.
447 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
449 * floatfns.c: Simplify discussion of functions that Emacs doesn't
450 support, by removing commented-out code and briefly listing the
451 C89 functions excluded. The commented-out stuff was confusing
452 maintenance, e.g., we thought we needed cbrt but it was commented out.
453 (logb): Remove decl; no longer needed.
454 (isfinite): New macro, if not already supplied.
455 (isnan): Don't replace any existing macro.
456 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
457 are present on all C89 platforms.
458 (Ffrexp): Do not special-case zero, as frexp does the right thing
460 (Flogb): Do not use logb, as it doesn't have the desired meaning
461 on hosts that use non-base-2 floating point. Instead, stick with
462 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
463 frexp, to avoid getting an unspecified result.
465 * xdisp.c (Qinhibit_debug_on_message): Now static.
467 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
469 * nsterm.m (ns_update_begin): Set clip path to whole view by using
470 NSBezierPath (Bug#12131).
472 2012-09-10 Chong Yidong <cyd@gnu.org>
474 * fns.c (Fdelq, Fdelete): Doc fix.
476 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
478 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
479 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
481 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
483 * lisp.h (make_lisp_ptr): New macro to replace XSET.
484 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
487 2012-09-09 Eli Zaretskii <eliz@gnu.org>
489 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
490 left fringe if the window has a left margin. This avoids leaving
491 traces of the cursor because its leftmost pixel is not drawn over.
493 * dispnew.c (update_window_line): When the left margin area of a
494 screen line is updated, set the redraw_fringe_bitmaps_p flag of
495 that screen line. (Bug#12277)
497 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
499 Assume C89 or later for math functions (Bug#12381).
500 This simplifies the code, and makes it a bit smaller and faster,
501 and (most important) makes it easier to clean up signal handling
502 since we can stop worring about floating-point exceptions in
503 library code. That was a problem before C89, but the problem
504 went away many years ago on all practical Emacs targets.
505 * data.c, image.c, lread.c, print.c:
506 Don't include <math.h>; no longer needed.
507 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
508 might be autoconfigured, as that never happens.
510 * doprnt.c (DBL_MAX_10_EXP):
512 Remove. C89 or later always defines these.
513 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
514 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
515 (arith_error, domain_error, domain_error2):
516 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
517 no longer needed -- we simply return what C returns. All uses removed.
518 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
520 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
521 Remove. All uses expanded, as these macros are no longer used
522 more than once and are now more trouble than they're worth.
523 (Ftan): Use tan, not sin / cos.
524 (Flogb): Assume C89 frexp.
525 (fmod_float): Assume C89 fmod.
526 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
527 (init_floatfns): Remove. All uses removed.
529 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
531 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
532 compositeToPoint for OSX < 10.6 (Bug#12390).
534 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
536 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
537 This produces more-accurate results.
539 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
541 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
544 2012-09-08 Chong Yidong <cyd@gnu.org>
546 * syntax.c (Fstring_to_syntax): Doc fix.
548 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
550 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
551 in the internal border.
552 (x_set_window_size): Remove static variables and their usage.
553 (ns_redraw_scroll_bars): Fix NSTRACE arg.
554 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
555 fringe/internal border adjustment (Bug#11052).
556 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
557 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
558 (ns_fix_rect_ibw): Remove.
559 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
560 (ns_dumpglyphs_box_or_relief): Ditto.
561 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
563 (ns_dumpglyphs_image): Ditto.
564 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
566 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
567 their usage. Add fringe_extended_p and its use as in other terms.
568 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
569 scroll bar was removed.
570 (updateFrameSize): New function.
571 (windowDidResize): Move code to updateFrameSize and call it.
573 * nsterm.h (EmacsView): Add updateFrameSize.
575 2012-09-07 Chong Yidong <cyd@gnu.org>
577 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
579 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
581 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
583 More signal-handler cleanup (Bug#12327).
584 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
585 Problem introduced when merging patches. Noted by Eli Zaretskii in
586 <http://bugs.gnu.org/12327#67>.
587 * floatfns.c: Comment fix.
588 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
589 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
590 and anyway the declaration is harmless even if SIGDANGER is not defined.
591 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
592 defined BROKEN_FIONREAD). systty.h formerly did this, but other
593 source files not surprisingly expected syssignal.h to define, or
594 not define, SIGIO, and it's cleaner to do it that way, for consistency.
595 Include <sys/ioctl.h>, for FIONREAD.
596 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
597 This eliminates a problem whereby other files mysteriously had
598 to include "syssignal.h" before including "systty.h" if they
599 wanted to use "#ifdef SIGIO".
601 2012-09-07 Eli Zaretskii <eliz@gnu.org>
603 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
605 * w32.c (sigemptyset): Empty the set.
606 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
608 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
610 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
612 * alloc.c (mark_buffer): Revert unsafe marking optimization.
613 (mark_object): Likewise for frame objects.
615 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
617 * syssignal.h (handle_on_main_thread): Always declare,
618 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
619 This ports to platforms without HAVE_PTHREAD.
621 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
623 Signal-handler cleanup (Bug#12327).
624 Emacs's signal handlers were written in the old 4.2BSD style with
625 sigblock and sigmask and so forth, and this led to some
626 inefficiencies and confusion. Rewrite these to use
627 pthread_sigmask etc. without copying signal sets around. Also,
628 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
629 'signal', and instead use functions that do not attempt to take
630 over the system name space. This patch causes Emacs's text
631 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
632 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
633 Do not include <signal.h> or "syssignal.h", as these
634 modules do not use signals.
635 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
636 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
637 Do not include <signal.h>, as "syssignal.h" does that for us now.
638 * atimer.c (sigmask_atimers): New function.
639 (block_atimers, unblock_atimers): New functions,
640 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
642 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
643 no longer needed here.
644 * emacs.c (main): Inspect existing signal handler with sigaction,
645 so that there's no need to block and unblock SIGHUP.
646 * sysdep.c (struct save_signal): New member 'action', replacing
647 old member 'handler'.
648 (save_signal_handlers, restore_signal_handlers):
649 Use sigaction instead of 'signal' to save and restore.
650 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
651 New function. All users of 'signal' modified to use set_sighandler
652 if they're writeonly, and to use sys_signal if they're read+write.
653 (emacs_sigaction_init, forwarded_signal): New functions.
654 (sys_signal): Remove. All uses replaced by calls to sigaction
655 and emacs_sigaction_init, or by direct calls to 'signal'.
656 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
657 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
658 all uses replaced by pthread_sigmask etc. calls.
659 * syssignal.h: Include <signal.h>.
660 (emacs_sigaction_init, forwarded_signal): New decls.
661 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
662 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
663 (sigmask, sys_sigmask): Remove; no longer needed.
664 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
665 (sigblock, sigunblock, sigfree):
666 (sigsetmask) [!defined sigsetmask]:
667 Remove. All uses replaced by pthread_sigmask.
668 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
669 no longer need to be replaced, and its typical old uses
670 are now done via emacs_sigaction_init and sigaction.
671 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
672 (sys_sigdel): Remove; unused.
673 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
675 2012-09-06 Eli Zaretskii <eliz@gnu.org>
677 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
678 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
680 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
682 Explicitly mark buffer_defaults and buffer_local_symbols.
683 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
684 mark_local_symbols here.
685 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
686 since special buffers aren't marked here any more.
687 (allocate_buffer): Chain new buffer with all_buffers here...
688 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
690 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
691 (syms_of_buffer): Remove staticpro of the above.
692 (init_buffer_once): Set names for buffer_defaults and
693 buffer_local_symbols.
695 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
697 Use bool for booleans in font-related modules.
698 * font.c (font_intern_prop, font_style_to_value)
699 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
700 (generate_otf_features, font_check_otf_features, font_check_otf)
701 (font_match_p, font_list_entities, font_at):
702 * fontset.c (fontset_id_valid_p, reorder_font_vector
703 (fontset_find_font, Fset_fontset_font)
704 (face_suitable_for_char_p) [0]:
705 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
706 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
707 (m17n_flt_initialized, ftfont_shape_by_flt):
708 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
709 * nsfont.m (nsfont_draw):
710 * w32font.c (w32font_draw):
711 * w32term.c (x_draw_glyphless_glyph_string_foreground):
712 Use bool for booleans.
713 * font.h: Adjust to above API changes.
714 (struct font, struct font_driver, struct font_driver_list):
715 Use bool for booleans.
716 (struct font): Remove useless member encoding_type.
718 * fontset.c, xftfont.c: Omit unnecessary static decls.
720 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
722 * alloc.c (mark_object): Revert window marking code
723 since it's unsafe for the Fset_window_configuration.
725 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
727 Fix race conditions with signal handlers and errno (Bug#12327).
728 Be more systematic about preserving errno whenever a signal
729 handler returns, even if it's not in the main thread. Do this by
730 renaming signal handlers to distinguish between signal delivery
731 and signal handling. All uses changed.
732 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
733 * data.c (deliver_arith_signal): Rename from arith_error.
734 * dispnew.c (deliver_window_change_signal): Rename from
735 window_change_signal.
736 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
737 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
738 * keyboard.c (deliver_input_available_signal): Rename from
739 input_available_signal.
740 (deliver_user_signal): Rename from handle_user_signal.
741 (deliver_interrupt_signal): Rename from interrupt_signal.
742 * process.c (deliver_pipe_signal): Rename from send_process_trap.
743 (deliver_child_signal): Rename from sigchld_handler.
744 * atimer.c (handle_alarm_signal):
745 * data.c (handle_arith_signal):
746 * dispnew.c (handle_window_change_signal):
747 * emacs.c (handle_fatal_signal, handle_danger_signal):
748 * keyboard.c (handle_input_available_signal):
749 * keyboard.c (handle_user_signal, handle_interrupt_signal):
750 * process.c (handle_pipe_signal, handle_child_signal):
751 New functions, with the actual signal-handling code taken from the
752 original respective signal handlers, sans the sporadic attempts to
753 preserve errno, since that's now done by handle_on_main_thread.
754 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
755 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
756 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
758 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
759 Move initialization of main_thread to sysdep.c's init_signals.
760 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
761 our usage, and simplifies the mainline code.
762 (record_child_status_change): New static function, as a helper
763 for handle_child_signal, and with most of the old child handler's
765 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
766 (handle_child_signal): Use the above.
767 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
768 Moved here from emacs.c.
769 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
770 code moved here from emacs.c's main function.
771 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
772 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
773 lets callers save and restore errno properly.
775 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
777 Remove redundant or unused things here and there.
778 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
779 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
780 * editfns.c (Fcompare_buffer_substrings): Likewise.
781 * frame.h (struct terminal, struct font_driver_list):
782 Remove redundant declarations.
783 * window.h (Qleft, Qright): Likewise.
785 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
787 Do not mark objects from deleted buffers, windows and frames.
788 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
789 (mark_object): Likewise for windows and frames.
791 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
793 * alloc.c (valid_lisp_object_p): Treat killed buffers,
794 buffer_defaults and buffer_local_symbols as valid objects.
795 Return special value to denote them.
797 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
799 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
800 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
801 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
802 (file_name_absolute_p, Fsubstitute_in_file_name):
803 (check_executable, check_writable, Ffile_accessible_directory_p)
804 (Fset_file_selinux_context, Fdefault_file_modes)
805 (Finsert_file_contents, choose_write_coding_system)
806 (Fwrite_region, build_annotations, a_write, e_write)
808 * filelock.c (boot_time_initialized, get_boot_time)
809 (get_boot_time_1, lock_file_1, within_one_second):
810 * floatfns.c (in_float):
811 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
812 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
813 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
814 * lisp.h (struct Lisp_Hash_Table.cmpfn):
815 * window.c (compare_window_configurations):
816 Use bool for booleans.
817 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
818 (Fdefault_file_modes): Now mode_t, not int, for modes.
819 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
820 (internal_delete_file): Now returns void, not a (boolean) int,
821 since nobody was looking at the return value.
822 * lisp.h, window.h: Adjust to above API changes.
824 * xdisp.c (set_message): Simplify and reindent last change.
826 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
828 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
830 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
832 * eval.c (call_debugger): Make the function non-static so that we
833 can call it from set_message.
835 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
836 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
838 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
840 Give more-useful info on a fatal error (Bug#12328).
841 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
842 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
843 of doing the work ourselves.
844 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
846 (fatal_error_backtrace): New function, taken from the guts
847 of the old fatal_error_signal, but with a new option to output
849 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
850 info about the signal than just its number.
851 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
852 * sysdep.c: Include <execinfo.h>
853 (emacs_backtrace): New function, taken partly from the previous
854 code of the 'die' function.
855 (emacs_abort): Call fatal_error_backtrace rather than abort.
857 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
859 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
860 eager (load-time) macro-expansion.
861 * lisp.mk (lisp): Add macroexp.
863 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
865 Simplify redefinition of 'abort' (Bug#12316).
866 Do not try to redefine the 'abort' function. Instead, redo
867 the code so that it calls 'emacs_abort' rather than 'abort'.
868 This removes the need for the NO_ABORT configure-time macro
869 and makes it easier to change the abort code to do a backtrace.
870 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
871 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
872 Remove; sysdep.c's emacs_abort now takes its place.
873 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
874 'abort' changed to use 'emacs_abort'.
875 * msdos.c (dos_abort) [defined abort]: Remove; not used.
876 (abort) [!defined abort]: Rename to ...
877 (emacs_abort): ... new name.
878 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
879 the place of the old 'abort' in emacs.c.
880 * w32.c, w32fns.c (abort): Do not #undef.
881 * w32.c (emacs_abort): Rename from w32_abort.
883 2012-09-04 Eli Zaretskii <eliz@gnu.org>
885 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
886 offsets[j].dv, since the y axis of the screen coordinates points
887 down, while the y axis of the font definition coordinates points
888 up. This fixes display of Arabic diacritics such as KASRA and
889 KASRATAN. (Bug#11860)
891 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
893 Be more systematic about _setjmp vs setjmp.
894 * alloc.c (test_setjmp, mark_stack):
895 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
896 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
897 (png_load, my_error_exit, jpeg_load):
898 * process.c (send_process_trap, send_process):
899 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
900 The underscored versions are up to 30x faster on some hosts.
901 Formerly, the code used setjmp+longjmp sometimes and
902 _setjmp+_longjmp at other times, with no particular reason to
903 prefer setjmp+longjmp.
905 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
907 Fix minor problem found by static checking.
908 * buffer.c (Fdelete_all_overlays): Return nil.
910 2012-09-03 Martin Rudalics <rudalics@gmx.at>
912 * buffer.c (Fdelete_all_overlays): New function.
914 2012-09-03 Chong Yidong <cyd@gnu.org>
916 * gtkutil.c: Add extern decl for Qxft.
918 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
920 * emacs.c, eval.c: Use bool for boolean.
921 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
922 (malloc_using_checking) [DOUG_LEA_MALLOC]:
923 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
924 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
925 (main, decode_env_path, Fdaemon_initialized):
926 * eval.c (call_debugger, Finteractive_p, interactive_p):
927 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
928 (maybe_call_debugger, Fbacktrace):
929 * process.c (read_process_output, exec_sentinel):

939 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
940 * msdos.c (fatal_error_in_progress): ... from here.
941 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead

1035 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
1036 more than one grapheme cluster passed to the shaper: compute the
1037 offset adjustment values separately for each cluster. (Bug#11860)
1039 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1040 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1041 about implicit conversions from integer to pointer.
1043 2012-09-01 Daniel Colascione <dancol@dancol.org>
1045 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

1099 window system declarations.
1101 * frame.h: Move common functions here: set_frame_menubar,
1102 x_set_window_size, x_sync, x_get_focus_frame,
1103 x_set_mouse_position, x_set_mouse_pixel_position,
1104 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

1190 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
1191 Add window_closed and button_values. Add void as return value for
1192 add(Button|String|Split). addButton takes int instead of Lisp_Object.
1193 Add process_dialog as new member.

1384 * charset.c (charset_map_loaded, load_charset_map, read_hex):
1385 (load_charset_map_from_file, map_charset_chars)
1386 (Fdefine_charset_internal, define_charset_internal)
1387 (Fdeclare_equiv_charset, find_charsets_in_text)
1388 (Ffind_charset_region, char_charset, Fiso_charset):
1389 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
1390 (sub_char_table_set, sub_char_table_set_range)
1391 (char_table_set_range, optimize_sub_char_table)
1392 (map_sub_char_table):
1393 Use bool for boolean.
1394 * character.c (str_to_unibyte): Omit last boolean argument; it was
1395 always 0. All callers changed.
1396 * character.h, charset.h: Adjust to match previous changes.
1397 * character.h (char_printable_p): Remove decl of nonexistent function.
1398 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
1399 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
1400 are all boolean, so make them single-bit bitfields.
1402 * lisp.h (ASET): Remove attempt to detect side effects.
1403 It was meant to be temporary and it often doesn't work,
1404 because when IDX has side effects the behavior of IDX==IDX
1405 is undefined. See Stefan Monnier in
1406 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
1408 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
1410 * lisp.h (functionp): New function (extracted from Ffunctionp).
1411 (FUNCTIONP): Use it.
1412 * eval.c (Ffunctionp): Use it.
1414 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1416 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
1417 as that's faster and simpler than static storage. Don't bother
1418 with the g_main_context_query overhead if g_main_context_pending
1419 says no events are pending.
1420 (gfds, gfds_size): Remove these static vars.
1421 (xgselect_initialize): Remove; no longer needed.
1422 All uses and decls removed.
1424 * emacs.c (fatal_error_signal_hook): Remove.
1425 All uses removed. This leftover from old code was always 0.
1427 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
1428 * casefiddle.c (casify_object, casify_region):
1429 * casetab.c (set_case_table):
1430 * category.c, category.h (word_boundary_p):
1431 * category.h (CHAR_HAS_CATEGORY):
1432 Use bool for booleans, instead of int.
1434 2012-08-25 Eli Zaretskii <eliz@gnu.org>
1436 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
1438 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1440 On assertion failure, print backtrace if available.
1441 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1442 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1443 * Makefile.in (LIB_EXECINFO): New macro.
1446 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1447 * bytecode.c (exec_byte_code):
1448 * callint.c (check_mark, Fcall_interactively):
1449 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1450 (getenv_internal, sync_process_alive, call_process_exited):
1451 * lisp.h (USE_SAFE_ALLOCA):
1452 Use bool for booleans, instead of int.
1453 * lisp.h, process.h: Adjust prototypes to match above changes.
1454 * callint.c (Fcall_interactively): Don't assume the mark's
1455 offset fits in 'int'.
1457 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1459 * buffer.c, buffer.h: Use bool for boolean.
1460 * buffer.c (reset_buffer_local_variables)
1461 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1462 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
1463 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
1464 (overlay_touches_p, overlay_strings, Foverlay_put)
1465 (report_overlay_modification, call_overlay_mod_hooks):
1466 (mmap_enlarge, mmap_set_vars):
1467 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1468 Use bool for booleans, instead of int.
1469 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1470 since the 1-or-0 return value is always ignored anyway.
1471 (mmap_initialized_p):
1472 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1473 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1475 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1477 * bidi.c: Use bool for boolean.
1478 This is a bit more readable, and makes the text segment of bidi.o
1479 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1480 Presumably it's faster too.
1481 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1483 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1484 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1485 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1486 (bidi_explicit_dir_char, bidi_level_of_next_char)
1487 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1488 Use bool for booleans, instead of int.
1489 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1490 (bidi_unshelve_cache): Adjust decls to match code.
1492 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1494 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1497 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1499 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1500 * atimer.h: Include <stdbool.h>.
1502 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1504 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1505 compile time tests instead of run time tests on systems that do
1507 (FRAME_MAC_P): Remove leftover from deleted code.
1508 * frame.c (syms_of_frame): Remove leftover from deleted code.
1510 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
1512 * nsterm.m (insertText:): Don't clear modifiers if code is space.
1514 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1516 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1517 Otherwise, the compiler complains about (A?B:C) where B is void
1518 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1519 (fontset_add): Return void, for FONTSET_ADD.
1521 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1523 * alloc.c: Use bool for booleans.
1524 (gc_in_progress, abort_on_gc)
1525 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1526 (dont_register_blocks) [GC_MALLOC_CHECK]:
1527 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1528 (check_string_bytes, make_specified_string, memory_full)
1529 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1530 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1531 (mark_stack, valid_pointer_p, make_pure_string)
1532 (Fgarbage_collect, survives_gc_p, gc_sweep):
1533 Use bool for booleans, instead of int.
1534 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1535 Remove unused local.
1536 * alloc.c (PURE_POINTER_P):
1537 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1538 * editfns.c (Fformat):
1539 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1541 * fns.c (sweep_weak_table):
1542 * lisp.h (suppress_checking, push_message, survives_gc_p)
1543 (make_pure_string, gc_in_progress, abort_on_gc):
1544 * lread.c (readchar, read1):
1545 * print.c (Fprin1_to_string):
1546 * xdisp.c (push_message):
1547 Use bool for booleans affected directly or indirectly by
1550 Make recently-introduced setters macros.
1551 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1552 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1553 (set_fontset_default, set_fontset_fallback): Rename from their
1554 upper-case counterparts, and make them functions rather than macros.
1555 This is more consistent with the other recently-introduced setters.
1556 These don't need to be inline, since they're local.
1558 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1560 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1561 the loop (Bug#12247).
1563 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1565 * lisp.h (vcopy): Use memcpy rather than our own loop.
1566 This fixes a performance regression introduced by the recent
1567 addition of vcopy. This means 'vcopy' will need to be modified
1568 for a copying collector, but that's OK. Also, tighten the
1569 checking in the assertion.
1571 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1573 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1574 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1575 non-base glyph for the width of the base character, according to
1576 what x_draw_composite_glyph_string_foreground expects.
1577 Generate WADJUST value according to composition_gstring_width's
1578 expectations, to produce correct width of the composed character.
1579 Reverse the sign of the DU offset produced by ScriptPlace.
1581 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1583 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1585 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1587 Avoid direct writes to contents member of struct Lisp_Vector.
1588 * lisp.h (vcopy): New function to copy data into vector.
1589 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
1590 * fns.c (Ffillarray): Use ASET.
1591 * keyboard.c (timer_check_2): Use AREF and ASET.
1592 (append_tool_bar_item, Frecent_keys): Use vcopy.
1593 * lread.c (read_vector): Use ASET.
1594 * msdos.c (Frecent_doskeys): Use vcopy.
1595 * xface.c (Finternal_copy_lisp_face): Use vcopy.
1596 (Finternal_merge_in_global_face): Use ASET and vcopy.
1597 * xfont.c (xfont_list_pattern): Likewise.
1599 2012-08-21 Martin Rudalics <rudalics@gmx.at>
1601 * window.c (Fwindow_point): For the selected window always return
1602 the position of its buffer's point.
1603 (Fset_window_point): For the selected window always go in its
1604 buffer to the specified position.
1606 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1608 Setter macros for fontsets.
1609 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1610 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1611 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1614 2012-08-20 Glenn Morris <rgm@gnu.org>
1616 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1617 Don't assume that `ln -f' works.
1619 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1621 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1622 and later about non-assignments with no effect. See discussion at
1623 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1626 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1628 Inline setter functions for Lisp_Objects slots of struct specbinding.
1629 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
1632 2012-08-20 Martin Rudalics <rudalics@gmx.at>
1634 * window.c (select_window): Always make selected window's buffer
1637 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1639 Use AREF and ASET for docstrings of category tables.
1640 * category.h (CATEGORY_DOCSTRING): Use AREF.
1641 (SET_CATEGORY_DOCSTRING): Use ASET.
1642 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
1644 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1646 Inline setter functions for hash table members.
1647 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
1648 (set_hash_hash, set_hash_index): Rename with _slot suffix.
1649 (set_hash_key_and_value, set_hash_index, set_hash_next)
1650 (set_hash_hash): New functions.
1651 * charset.c, fns.c: Adjust users.
1653 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1655 Inline getter and setter functions for per-buffer values.
1656 * buffer.h (per_buffer_default, set_per_buffer_default)
1657 (per_buffer_value, set_per_buffer_value): New functions.
1658 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
1659 * buffer.c, data.c: Adjust users.
1661 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
1663 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
1665 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
1667 Rely on <config.h> + <unistd.h> to declare 'environ',
1668 as gnulib does this if the system doesn't.
1669 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
1670 Remove declaration. MS-Windows declares it on stdlib.h which is
1671 included by conf_post.h.
1672 * emacs.c (environ) [DOUG_LEA_MALLOC]:
1673 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
1674 * vm-limit.c: Include <unistd.h>, for 'environ'.
1676 * unexaix.c, unexcoff.c: Include "mem-limits.h".
1677 (start_of_data): Remove decl; mem-limits.h provides it.
1679 * xdisp.c (handle_invisible_prop): Make it a bit faster
1680 and avoid a gcc -Wmaybe-uninitialized diagnostic.
1682 2012-08-19 Chong Yidong <cyd@gnu.org>
1684 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
1687 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
1689 * .gdbinit: Use call instead of set when calling a function in the
1692 * data.c (set_internal): Don't use set_blv_found.
1693 (Fkill_local_variable): Likewise.
1695 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
1697 * nsfont.m (ns_ascii_average_width): Ensure the string
1698 ascii_printable is initialized with a null-terminated character
1699 array. Otherwise, it can contain undesired extra characters.
1701 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1703 port new setting code to Sun C 5.8 2005/10/13
1704 * chartab.c, lisp.h (char_table_set, char_table_set_range):
1705 Return void, not Lisp_Object. Otherwise, the compiler
1706 complains about (A?B:C) where B is void and C is Lisp_Object
1707 when compiling CHAR_TABLE_SET, due to the recent change to
1708 the API of sub_char_table_set_contents.
1710 2012-08-18 Chong Yidong <cyd@gnu.org>
1712 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
1713 for the string case (Bug#3874).
1715 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1717 * buffer.h (BSET): Remove (Bug#12215).

1787 New setter functions.
1789 * termhooks.h (TSET): Remove (Bug#12215).
1790 Replace all uses with calls to new setter functions.
1791 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
1792 (TERMHOOKS_INLINE): New macro.
1793 (tset_charset_list, tset_selection_alist): New setter functions.
1794 * terminal.c (TERMHOOKS_INLINE):
1795 Define to EXTERN_INLINE, so that the corresponding functions
1796 are compiled into code.
1797 (tset_param_alist): New setter function.
1799 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
1801 * keyboard.h (KSET): Remove (Bug#12215).

2545 value of EMACSLOADPATH, as it is no longer needed.
2546 (check_windows_init_file): Now external, not static.

2597 * alloc.c (record_xmalloc): New function.
2598 * lisp.h (record_xmalloc): New decl.
2599 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
2600 more like a function. This is because the pointer cast is not
2601 needed. All uses changed.
2602 * print.c (print_string, print_error_message): Avoid length recalc.
2604 Improve fix for macroexp crash with debugging (Bug#12118).
2605 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
2606 ARRAY_MARK_FLAG when checking subscripts, because ASET is

2639 with addition of handling of symlinks and support for 'lstat'.
2640 If possible, get file's attributes and security information by
2641 handle, not by name. Produce S_IFLNK bit for symlinks, when
2642 called from 'lstat'.
2643 (stat, lstat): New functions, call 'stat_worker'.
2644 (symlink, readlink, careadlinkat): Rewritten to create and resolve
2645 symlinks when the underlying filesystem supports them.

2649 Fix macroexp crash on Windows with debugging (Bug#12118).
2650 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
2651 checking subscripts; problem introduced with the recent
2652 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
2653 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
2654 since it's used in non-static inline functions now.
2656 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

3151 is an integer literal.
3152 (xgetint): Simplify expression.
3153 * alloc.c (gdb_make_enums_visible): New constant. This ports to
3154 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
3155 Zaretskii in <http://bugs.gnu.org/12036#13>.
3156 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
3157 needed now that we have gdb_make_enums_visible.
3158 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
3159 (enum enum_USE_LSB_TAG):
3160 New enum types, packaging up enums that need to be exported to GDB.
3162 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

3178 * xdisp.c (syms_of_xdisp): Likewise.
3179 * xfns.c (syms_of_xfns): Likewise.
3181 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3183 Fast save_excursion_save and save_excursion_restore.
3184 * lisp.h (struct Lisp_Excursion): New data type.
3185 (PVEC_EXCURSION): New pseudovector type.
3186 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
3187 to deal with it. Adjust comments.
3188 (init_marker, attach_marker): New prototype.
3189 (unchain_marker): Adjust prototype.

3198 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
3200 Fix export of symbols to GDB (Bug#12036).
3201 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
3202 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
3203 emacs.c, as this is a more-suitable home. Had this been done earlier
3204 the fix for 12036 would have avoided some of the problems noted in
3205 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
3206 would have been more obvious.
3207 * emacs.c: Do not include <verify.h>; no longer needed.
3208 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
3209 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
3210 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3211 Remove; now done in lisp.h.
3212 * lisp.h (PUBLISH_TO_GDB): New macro.

3214 (DATA_SEG_BITS): Use it.
3215 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
3216 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3217 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3218 not be usable in #if. This simplifies things.
3220 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
3222 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
3224 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

3227 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3228 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3229 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3230 Adjust to changes in lisp.h and emacs.c, by using
3231 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
3232 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
3233 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
3234 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
3235 instead of gdb_valbits.
3236 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
3237 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
3238 instead of gdb_array_mark_flag.
3239 (xboolvector): Get size from $->size, not $->header.size.
3240 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
3241 (xreload, hook-run, hookpost-run): Remove.
3242 * emacs.c: Include <verify.h>.
3243 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
3244 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
3246 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
3247 (gdb_USE_LSB_TAG): New enum constants.
3248 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3249 Also define these as enum constants, so they're visible to GDB.
3250 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
3251 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
3252 as constants, so they're visible to GDB.
3253 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
3254 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
3255 Now enum constants, not macros, so they're visible to GDB.
3256 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
3257 more convenient now. All uses changed.
3258 (VALMASK) [USE_LSB_TAG]: Also define in this case.
3259 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
3261 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

3268 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
3269 add argument, tune behavior, and adjust all callers.
3271 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
3273 Use typedef for EMACS_INT, EMACS_UINT.
3274 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
3275 than macros. This simplifies debugging in the usual case, since
3276 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
3277 and it allows expressions involving EMACS_INT casts.
3278 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
3280 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

3290 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
3292 Adjust buffer text indirection counters at the end of Fkill_buffer.
3293 * buffer.c (Fkill_buffer): Adjust indirection counters when the
3294 buffer is definitely dead. This should really fix an issue reported
3295 by Christoph Scholtes again. (Bug#12007).
3296 (init_buffer_once): Initialize indirection counters of
3297 buffer_defaults and buffer_local_symbols (for sanity and safety).
3299 2012-07-24 Eli Zaretskii <eliz@gnu.org>
3301 * xdisp.c (init_iterator): Don't compute dimensions of truncation
3302 and continuation glyphs on tooltip frames, leave them at zero.
3303 Avoids continued lines in tooltips. (Bug#11832)
3305 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

3330 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3332 Swap buffer text indirection counters in Fbuffer_swap_text.
3333 * buffer.c (Fbuffer_swap_text): Swap indirections too.
3334 This avoids crash reported by Christoph Scholtes at
3335 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
3337 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
3339 * nsmenu.m (Popdown_data): New struct.

3344 and autorelease them. Also autorelease img and matrix (Bug#12005).
3345 (dealloc): Remove (Bug#12005).

3362 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
3364 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
3365 as it's limited by the amount of memory, not by INT_MAX.
3367 2012-07-21 Eli Zaretskii <eliz@gnu.org>
3369 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
3370 in special-event-map. See the discussion at

3451 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
3452 'for_each_per_buffer_object_at'.
3453 All uses changed. It's better to use upper-case for macros that
3454 cannot be implemented as functions, to give the reader a clue
3455 that they're special.
3457 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>

3503 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
3505 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
3507 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
3508 when invoking (make-bool-vector N t) and N is a positive

3516 padding before the data member of a bool vector.
3517 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
3518 than doing the check by hand with an abort ().
3520 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3522 * eval.c (Fdefvar): Don't check constants since we only set the var if
3523 it's not yet defined anyway (bug#11904).
3525 * lisp.h (last_undo_boundary): Declare new var.
3526 * keyboard.c (command_loop_1): Set it.
3527 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
3528 were auto-added by the command loop (bug#11774).
3530 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
3532 * w32font.c (Qsymbol): Remove local definition.

4040 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
4041 function attribute, so we only use it if it exists in the
4044 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
4046 Avoid call to strlen in fast_c_string_match_ignore_case.
4047 * search.c (fast_c_string_match_ignore_case): Change to use
4048 length argument. Adjust users accordingly.
4049 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
4051 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

4093 * s/aix4-2.h (unix): Remove; no longer needed.
4095 EMACS_TIME simplification (Bug#11875).
4096 This replaces macros (which typically do not work in GDB)
4097 with functions, typedefs and enums, making the code easier to debug.
4098 The functional style also makes code easier to read and maintain.
4099 * systime.h: Include <sys/time.h> on all hosts, not just if
4100 WINDOWSNT, since 'struct timeval' is needed in general.
4101 (EMACS_TIME): Now a typedef, not a macro.
4102 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
4104 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

4107 (EMACS_TIME_LE): Now functions, not macros.
4108 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
4109 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
4110 which are not functions. All uses rewritten to use:
4111 (make_emacs_time): New function.
4112 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
4113 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4114 not functions. All uses rewritten to use the following, respectively:
4115 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
4116 (add_emacs_time, sub_emacs_time): New functions.
4117 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
4118 * fileio.c (Fcopy_file):
4119 * xterm.c (XTflash): Get the current time closer to when it's used.
4120 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

4127 * frame.c (Fmake_terminal_frame):
4128 * gtkutil.c (get_utf8_string):
4130 * nsmenu.m (ns_update_menubar):
4131 * regex.c (regerror):
4132 Prefer memcpy to strncpy and strncat when either will do.
4133 * fileio.c (Fsubstitute_in_file_name):
4134 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
4135 (menu_separator_name_p):
4136 * nsmenu.m (ns_update_menubar):
4137 Prefer memcmp to strncmp when either will do.
4138 * nsterm.m: Include <ftoastr.h>.
4140 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
4141 Prefer snprintf to strncpy.
4142 * nsterm.m (ns_term_init):
4143 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4144 * nsterm.m (ns_term_init):
4145 Avoid the need for strncpy, by using build_string or
4146 make_unibyte_string directly. Use dtoastr, not snprintf.
4147 * process.c (Fmake_network_process): Diagnose service names that
4148 are too long, rather than silently truncating them or creating
4149 non-null-terminated names.
4150 (Fnetwork_interface_info): Likewise, for interface names.
4151 * sysdep.c (system_process_attributes) [GNU_LINUX]:
4152 Prefer sprintf to strncat.
4153 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
4154 Prefer vsnprintf to vsprintf + strncpy.
4156 2012-07-10 Glenn Morris <rgm@gnu.org>
4158 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
4159 Clarify fallback case.
4161 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4163 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
4164 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
4165 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
4166 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
4167 where argument type is known to be a Lisp_Cons.
4169 2012-07-10 Tom Tromey <tromey@redhat.com>
4171 * bytecode.c (BYTE_CODE_THREADED): New macro.
4172 (BYTE_CODES): New macro. Replaces all old byte-code defines.

4179 Optimize pure C strings initialization.
4180 * lisp.h (make_pure_string): Fix prototype.
4181 (build_pure_c_string): New function, defined as static inline. This
4182 provides a better opportunity to optimize away calls to strlen when
4183 the function is called with compile-time constant argument.
4184 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
4185 argument, adjust users accordingly. Use build_pure_c_string where
4187 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
4188 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
4189 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
4191 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4193 Avoid calls to strlen in miscellaneous functions.
4194 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
4195 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
4196 * lread.c (openp): Likewise.
4198 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4200 Avoid calls to strlen in path processing functions.
4201 * fileio.c (file_name_as_directory): Add comment. Change to add
4202 srclen argument and return the length of result. Adjust users
4204 (directory_file_name): Fix comment. Change to add srclen argument,
4205 swap 1st and 2nd arguments to obey the common convention.
4206 Adjust users accordingly.
4207 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
4209 2012-07-10 Glenn Morris <rgm@gnu.org>
4211 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
4212 Move PENDING_OUTPUT_COUNT definition to configure.
4214 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):

4216 * s/gnu.h (DATA_START): Move definitions to configure.
4218 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
4219 We include usg5-4-common.h, which defines them both.
4221 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
4222 O_RDONLY already includes it).
4224 Stop ns builds setting the EMACSLOADPATH environment variable.
4225 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4226 Now it does not set EMACSLOADPATH, just returns the load-path string.
4227 * nsterm.h: Update accordingly.
4228 * lread.c [HAVE_NS]: Include nsterm.h.
4229 (init_lread) [HAVE_NS]: Use ns_load_path.
4230 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
4232 2012-07-09 Glenn Morris <rgm@gnu.org>
4234 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
4235 since the included bsd-common.h does so.
4237 Stop ns builds setting the EMACSPATH environment variable.
4238 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
4239 (ns_init_paths): Do not set EMACSPATH.
4240 * nsterm.h (ns_exec_path): Add it.
4241 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
4244 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
4246 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
4248 * process.c (wait_reading_process_output): 'waitchannels' was unset
4249 when read_kbd || !NILP (wait_for_cell); fix this.
4251 Add GCC-style 'const' attribute to functions that can use it.
4252 * character.h (char_resolve_modifier_mask):
4253 * keyboard.h (make_ctrl_char):
4254 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
4255 (init_character_once, next_almost_prime, init_fns, init_image)
4256 (flush_pending_output, init_sound):
4257 * mem-limits.h (start_of_data):

4261 Declare the dummy function with ATTRIBUTE_CONST.
4262 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
4263 Add decls with ATTRIBUTE_CONST.
4265 Minor improvements to make_formatted_string.
4266 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
4267 where int is good enough, as vsprintf returns an int.
4268 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
4270 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4272 Use make_formatted_string to avoid double length calculation.
4273 * lisp.h (make_formatted_string): New prototype.
4274 * alloc.c (make_formatted_string): New function.
4275 * buffer.c (Fgenerate_new_buffer_name): Use it.
4276 * dbus.c (syms_of_dbusbind): Likewise.

4279 * frame.c (make_terminal_frame, set_term_frame_name)
4280 (x_report_frame_params): Likewise.
4281 * image.c (gs_load): Likewise.
4282 * minibuf.c (get_minibuffer): Likewise.

4297 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4299 Move marker debugging code under MARKER_DEBUG.
4300 * marker.c (MARKER_DEBUG): Move marker debugging code under
4301 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4302 for bootstrap with --enable-checking (~3x slowdown reported
4303 by Juanma Barranquero <lekktu@gmail.com>).
4304 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4306 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4308 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
4309 See <http://bugs.gnu.org/11825#29>.
4311 2012-07-08 Eli Zaretskii <eliz@gnu.org>
4313 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4314 has no font, use the frame's font. (Bug#11813)
4315 (display_line): Add commentary about displaying truncation glyphs
4317 (produce_special_glyphs): Move here from term.c.
4319 * term.c (produce_special_glyphs): Move to xdisp.c.
4321 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4324 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4326 * xdisp.c (display_line): Avoid warning about implicit declaration
4329 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4331 * lisp.h: Remove empty conditional.
4333 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4335 * lread.c (load_path_check): Now static.
4337 Fix some minor --with-ns problems found by static checking.
4338 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
4339 (x_set_font) [!HAVE_X_WINDOWS]:
4340 * image.c (xpm_load_image) [HAVE_NS]:
4341 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4342 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4343 Remove unused local.
4344 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
4345 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
4346 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
4347 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
4348 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
4349 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
4350 Fix pointer signedness problem.
4351 * xfaces.c (FRAME_X_FONT_TABLE):
4352 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
4354 2012-07-07 Glenn Morris <rgm@gnu.org>
4356 * lread.c (load_path_check): New function, split from init_lread.
4357 (init_lread): Reorganize. Motivation:
4358 If EMACSLOADPATH is set, check/warn about that rather than the
4359 defaults, which we are not going to use. Hence we can remove
4360 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4361 Don't warn if site-lisp directories are missing.
4362 If not installed, start from a blank load-path, since
4363 PATH_LOADSEARCH refers to the eventual installation directories.
4365 2012-07-07 Eli Zaretskii <eliz@gnu.org>
4367 Support truncation and continuation glyphs on GUI frames, when
4368 fringes are disabled. (Bug#11832)
4369 * xdisp.c (init_iterator): Get dimensions of truncation and
4370 continuation glyphs even if on GUI frames.
4371 Adjust it->last_visible_x on GUI frames when the left or right fringes,
4372 or both, are absent.
4373 (start_display, move_it_in_display_line_to): Handle the case of a
4374 GUI frame without a fringe to display continuation or truncation
4376 (insert_left_trunc_glyphs): Support GUI frames: make sure
4377 truncation glyphs overwrite enough glyphs from the current line to
4378 have sufficient space in pixels.
4379 (display_line): Support truncation and continuation glyphs on GUI
4380 frames. If some spare pixels are left on the line after inserting
4381 the truncation glyphs, fill that space with a stretch glyph of a
4382 suitably computed width.
4384 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4385 produce_glyphs, to support GUI sessions.
4387 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4389 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4391 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4393 Do not require float-time's arg to fit in time_t (Bug#11825).
4394 This works better on hosts where time_t is unsigned, and where
4395 float-time is applied to the (negative) difference between two times.
4396 * editfns.c (decode_time_components): Last arg is now double *,
4397 not int *, and means to store all the result as a double, without
4398 worrying about whether the seconds part fits in time_t.
4399 All callers changed.
4400 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4401 All callers changed.
4402 (Ffloat_time): Do not fail merely because the specified time falls
4403 outside of time_t range.
4405 2012-07-07 Glenn Morris <rgm@gnu.org>
4407 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

4411 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
4413 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
4414 Update dependencies.
4416 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
4418 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4420 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
4421 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
4422 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
4423 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
4424 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
4425 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
4427 * xfont.c (compare_font_names): Redo to omit the need for casts.
4429 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4431 * xfns.c (Fx_change_window_property): Doc fix.
4432 * w32fns.c (Fx_change_window_property): Doc fix.
4434 * w32fns.c (Fx_window_property): Accept the same arguments as the
4435 X Windows version. Doc fix.
4436 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4438 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4439 Eli Zaretskii <eliz@gnu.org>
4441 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4442 Windows-specific code from nt/config.nt moved here.
4443 Obsolete settings removed.
4445 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4447 * process.c: Avoid unnecessary calls to gettime.
4448 (wait_reading_process_output): Don't get the time of day
4449 when gobbling data immediately and not waiting, as there's no need
4450 for it in that case. This removes a FIXME.
4452 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4454 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4455 is defined (Bug#11768).
4457 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4459 Fix marker debugging code.
4460 * marker.c (byte_char_debug_check): Do not perform the check
4461 if buffer is not multibyte.
4462 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4463 Call byte_char_debug_check with correct arguments.
4465 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4467 Compile marker debugging code only if ENABLE_CHECKING is defined.
4468 * marker.c (byte_char_debug_check, count_markers):
4469 Use only if ENABLE_CHECKING is defined.
4470 (byte_debug_flag): Remove.
4471 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4472 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4474 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4476 Avoid code repetition in marker-related functions.
4477 * marker.c (attach_marker): New function.
4478 (Fset_marker, set_marker_restricted, set_marker_both)
4479 (set_marker_restricted_both): Use it.
4480 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4481 Consistently rename charno to charpos.
4482 (marker_position): Add eassert.
4483 (marker_byte_position): Convert to eassert.

4489 * marker.c (unchain_marker): Simplify. Fix comments.
4491 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4493 Introduce fast path for the widely used marker operation.
4494 * alloc.c (build_marker): New function.
4495 * lisp.h (build_marker): New prototype.
4496 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
4497 * composite.c (autocmp_chars): Likewise.
4498 * editfns.c (buildmark): Remove.
4499 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
4500 (save_restriction_save): Use build_marker.
4501 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
4502 * window.c (save_window_save): Likewise.
4504 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4506 Do not use Fdelete_overlay in delete_all_overlays
4507 to avoid redundant calls to unchain_overlay.
4508 * buffer.c (drop_overlay): New function.
4509 (delete_all_overlays, Fdelete_overlay): Use it.
4510 * minibuf.c (get_minibuffer): Fix comment.
4512 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4514 Port to OpenBSD 5.1 amd64.
4515 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4516 This is needed for OpenBSD, and should be harmless on all BSD systems.
4517 Also, include <sys/sysctl.h>, as it should be available on all
4518 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4519 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4520 use p_pid member, not kp_proc.pid.
4522 2012-07-06 Glenn Morris <rgm@gnu.org>
4524 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4526 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4528 More xmalloc and related cleanup.
4529 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

4535 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
4536 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
4537 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4539 Omit needless casts involving void * pointers and allocation.
4540 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4541 as the former is more robust if P's type is changed.
4542 Prefer xzalloc to xmalloc + memset 0.
4543 Simplify malloc-or-realloc to realloc.
4544 Don't worry about xmalloc returning a null pointer.
4545 Prefer xstrdup to xmalloc + strcpy.
4546 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4548 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4549 alloca of a constant.
4551 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4553 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4554 hscroll is larger than the line width. Fixes long and futile
4555 looping inside extend_face_to_end_of_line (on a TTY) producing
4556 glyphs that are not needed and thrown away.
4558 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4560 * marker.c (set_marker_restricted_both): Simplify by using
4563 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4565 * editfns.c (region_limit): Simplify by using clip_to_bounds.
4567 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
4569 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
4570 not defined (Bug#11768).
4571 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
4572 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
4573 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
4574 followed by gtk_box_set_homogeneous (Bug#11768).
4575 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4576 (update_theme_scrollbar_width, xg_create_scroll_bar):
4577 Use gtk_scrollbar_new (Bug#11768).
4578 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
4579 (is_box_type): New function (Bug#11768).
4580 (xg_tool_item_stale_p): Call is_box_type.
4581 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
4582 with default display (Bug#11768).
4584 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4586 * xdisp.c (window_hscroll_limited): New function.
4587 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
4588 coordinates when window's hscroll is set to insanely large
4591 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
4593 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
4594 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
4596 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4599 * lisp.h (xzalloc): New prototype. Omit needless casts.
4600 * alloc.c (xzalloc): New function. Omit needless casts.
4601 * charset.c: Omit needless casts. Convert all calls to
4602 xmalloc with following memset to xzalloc.

4652 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4654 * fileio.c (time_error_value): Check the right error number.
4655 Problem reported by Troels Nielsen in
4656 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
4658 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4660 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
4661 This should be fixed in a better way; see Eli Zaretskii in
4662 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
4663 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
4665 * fileio.c (time_error_value): Rename from special_mtime.
4666 The old name's problems were noted by Eli Zaretskii in
4667 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
4669 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
4670 This variable's comment says Emacs needs at least one GDB-visible
4671 symbol of type enum pvec_type, to work around GDB problems.
4672 The symbol's value doesn't matter.
4674 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
4675 that causes compilation to fail on pre-C99 compilers.
4677 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
4679 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
4680 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
4682 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4684 * buffer.c (init_buffer_once): Fix initialization of
4685 headers for buffer_defaults and buffer_local_symbols.
4686 Reported by Juanma Barranquero <lekktu@gmail.com>.
4688 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
4690 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
4691 * lisp.h (enum pvec_type): Use fewer bits.
4692 (PSEUDOVECTOR_SIZE_BITS): New constant.
4693 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
4694 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
4695 change in pvec_type.
4696 (PSEUDOVECTOR_TYPEP): New macro.
4697 (TYPED_PSEUDOVECTORP): Use it.
4698 * fns.c (internal_equal): Adapt code to extract pvectype.
4699 * emacs.c (gdb_pvec_type): Update type.
4700 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
4701 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
4702 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
4703 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
4704 (sweep_vectors): Use it. Use local var `total_bytes' instead of
4705 abusing vector->header.next.nbytes.
4706 (live_vector_p): Use PVEC_TYPE.
4707 (mark_object): Adapt code to extract pvectype. Use switch.
4709 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4711 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
4712 Tighten new eassert a bit.
4714 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4716 Fix compilation with --enable-gcc-warnings and -O1
4718 * doprnt.c (doprnt): Change type of tem to int, initialize
4719 to avoid compiler warning. Add eassert.
4720 * search.c (simple_search): Initialize match_byte to avoid
4721 compiler warning. Add eassert.
4723 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4725 Avoid weird behavior with large horizontal scrolls.
4726 Without this change, for example, large hscroll values would
4727 mess up Emacs's display on Fedora 15 x86, presumably due to
4728 overflows in int calculations in the display code.
4729 Also, if buffers had long lines, Emacs would freeze.
4730 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
4731 (set_window_hscroll): New function, containing the old guts of
4732 Fset_window_hscroll. Return the clipped value.
4733 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
4734 This avoids the need to check against PTRDIFF_MAX.
4736 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
4738 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4740 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
4742 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4744 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
4745 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
4746 since GCC 4.4.6 issues a bogus warning for them.
4748 Fix bugs in file timestamp newness comparisons.
4749 * fileio.c (Ffile_newer_than_file_p):
4750 * lread.c (Fload): Use full timestamp resolution of files,
4751 not just the 1-second resolution, so that files that are only
4752 slightly newer still count as newer.
4753 * fileio.c (Ffile_newer_than_file_p): Don't assume file
4754 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
4756 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
4758 * fileio.c: Improve handling of file time marker. (Bug#11852)
4759 (special_mtime): New function.
4760 (Finsert_file_contents, Fverify_visited_file_modtime):
4761 Use it to set special mtime values consistently.
4763 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
4765 * fileio.c (Finsert_file_contents): Properly handle st_mtime
4766 marker for non-existing file. (Bug#11852)
4768 2012-07-03 Glenn Morris <rgm@gnu.org>
4770 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
4771 and did not make it into globals.h).
4773 2012-07-03 Tom Tromey <tromey@redhat.com>
4775 * window.c (Fset_window_margins, Fset_window_fringes)
4776 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
4777 * textprop.c (Fprevious_property_change): No longer static.
4778 * syntax.c (Fsyntax_table_p): No longer static.
4779 * process.c (Fget_process, Fprocess_datagram_address): No longer

4793 * dired.c (Ffile_attributes): No longer static.
4794 * composite.c (Fcomposition_get_gstring): No longer static.
4795 * callproc.c (Fgetenv_internal): No longer static.
4797 * ccl.h: Remove EXFUNs.
4798 * buffer.h: Remove EXFUNs.
4799 * dispextern.h: Remove EXFUNs.
4800 * intervals.h: Remove EXFUNs.
4801 * fontset.h: Remove EXFUN.
4802 * font.h: Remove EXFUNs.
4803 * dosfns.c (system_process_attributes): Remove EXFUN.
4804 * keymap.h: Remove EXFUNs.
4805 * lisp.h: Remove EXFUNs.
4806 * w32term.h: Remove EXFUNs.
4807 * window.h: Remove EXFUNs.
4808 * xsettings.h: Remove EXFUN.
4809 * xterm.h: Remove EXFUN.
4811 2012-07-03 Glenn Morris <rgm@gnu.org>
4813 * lisp.h (Frandom): Make it visible to C.
4814 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
4815 buffer for invisible buffers. (Bug#1229)
4817 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4819 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
4820 values which aren't power of 2.
4821 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
4822 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
4825 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
4827 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
4829 * alloc.c (mark_object): Revert part of last patch to use `switch'.
4831 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4833 * alloc.c (allocate_vector_block): Remove redundant
4834 calls to mallopt if DOUG_LEA_MALLOC is defined.
4835 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
4836 avoid calls to mallopt if zero_vector is returned.
4838 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4840 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
4841 is enabled, avoid dereferencing NULL current_sblock if
4844 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4846 Cleanup basic buffer management.
4847 * buffer.h (struct buffer): Change layout to use generic vector
4848 marking code. Fix some comments. Change type of 'clip_changed'
4849 to bitfield. Remove unused #ifndef old.
4850 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
4851 (GET_OVERLAYS_AT): Fix indentation.
4852 (for_each_per_buffer_object_at): New macro.
4853 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
4854 (Fbuffer_local_variables): Use it.
4855 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
4856 * alloc.c (allocate_buffer): Adjust to match new layout of
4857 struct buffer. Fix comment.
4858 (mark_overlay): New function.
4859 (mark_buffer): Use it. Use mark_vectorlike to mark normal
4860 Lisp area of struct buffer.
4861 (mark_object): Use it. Adjust marking of misc objects
4862 and related comments.
4864 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
4866 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
4867 wrapper that is not needed because the wrapped code is a no-op (zero
4868 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
4869 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
4871 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
4873 * alloc.c (mark_buffer): Simplify. Remove prototype.
4874 (mark_object): Add comment. Reorganize marking of vector-like
4875 objects. Use CHECK_LIVE for all vector-like objects except buffers
4876 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
4877 Avoid redundant calls to mark_vectorlike for bool vectors.
4879 2012-06-30 Glenn Morris <rgm@gnu.org>
4881 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
4883 * epaths.in (PATH_SITELOADSEARCH): New.
4884 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
4885 This is rather than relying on --enable-locallisppath elements
4886 having "site-lisp" in their names. (Bug#10208#25, 11658)
4888 2012-06-30 Eli Zaretskii <eliz@gnu.org>
4890 * w32proc.c (sys_select): Accept and ignore one more argument.
4892 * w32.c (emacs_gnutls_pull): Call select with one more argument.
4894 * sysselect.h [DOS_NT]: Don't include sys/select.h.
4895 (pselect) [!MS_DOS]: Redirect to sys_select.
4897 * sysdep.c: Don't include dos.h and dosfns.h.
4899 * process.c (sys_select):
4900 * msdos.c (sys_select): Accept one more argument and ignore it.
4902 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
4903 adapt data types and code to that.
4906 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
4907 which clashes with the gnulib function of the same name.
4909 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
4911 * font.c (font_style_to_value, font_style_symbolic)
4912 (font_prop_validate_style): Add type checks for values in
4915 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
4917 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
4920 2012-06-29 Eli Zaretskii <eliz@gnu.org>
4922 * xdisp.c (try_window_id): Undo last change.
4924 * w32.c (getwd): Adjust commentary about startup_dir.
4925 (init_environment): Always call sys_access, even in non-MSVC
4926 builds. Don't chdir to the directory of the Emacs executable.
4927 This undoes code from 1997 which was justified by the need to
4928 "avoid conflicts when removing and renaming directories". But its
4929 downside was that every relative file name was being interpreted
4930 relative to the directory of the Emacs executable, which can never
4931 be TRT. In particular, it broke sys_access when called with
4932 relative file names.
4933 (sys_access): Map GetLastError to errno.
4935 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4937 * window.h (struct window): Change type of 'fringes_outside_margins'
4938 to bitfield. Fix comment. Adjust users accordingly.
4939 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
4941 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
4944 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
4946 * gnutls.c (emacs_gnutls_handshake):
4947 Add QUIT to make the loop interruptible.
4949 2012-06-29 Glenn Morris <rgm@gnu.org>
4951 * charset.c (init_charset): Make lack of etc/charsets fatal.
4953 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4955 * editfns.c (region_limit): Fix type mismatch.
4957 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4959 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
4960 undefined. Convert from xassert to eassert.

5127 Use sprintf return value instead of invoking strlen on result.
5128 In the old days this wasn't portable, since some sprintf
5129 implementations returned char *. But they died out years ago and
5130 Emacs already assumes sprintf returns int.
5131 Similarly for float_to_string.
5132 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

5140 Use sprintf or float_to_string result to avoid need to call strlen.
5141 * data.c (Fnumber_to_string):
5142 Use make_unibyte_string, since the string must be ASCII.
5143 * lisp.h, print.c (float_to_string): Now returns int length.
5144 * term.c (produce_glyphless_glyph):
5145 Use sprintf result rather than recomputing it.
5147 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
5148 * Makefile.in (ALL_CFLAGS):
5149 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

5178 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
5180 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

5183 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
5185 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
5186 instead of truncating it to 63 (admittedly a generous limit).

5246 * keyboard.c (kbd_buffer_get_event):
5247 * process.c (Faccept_process_output):
5248 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
5249 This improves on the previous patch, which introduced a bug
5250 when time_t is unsigned and as wide as intmax_t.
5251 See <http://bugs.gnu.org/9000#51>.
5253 2012-06-23 Eli Zaretskii <eliz@gnu.org>

5316 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5318 Support higher-resolution time stamps (Bug#9000).
5319 The time stamps are only nanosecond-resolution at the C level,
5320 since that's the best that any real-world system supports now.
5321 But they are picosecond-resolution at the Lisp level, as that's
5322 easy, and leaves room for future OS improvements.
5324 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5327 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5328 Don't get current time unless it's needed.
5330 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5331 now provides it if it's absent.
5332 (start_atimer): Port to higher-res time stamps.
5333 Check for time stamp overflow. Don't get current time more
5334 often than is needed.
5336 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5337 Include systime.h, not time.h.
5338 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
5340 * dired.c: Include stat-time.h.
5341 (Ffile-attributes): File times now have higher resolution.

5344 (struct image): Timestamp now has higher resolution.
5346 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5347 has at least microseconds now. All uses removed.
5348 (update_frame, update_single_window, update_window, update_frame_1)
5349 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5350 (duration_to_sec_usec): Remove; no longer needed.
5352 * editfns.c (time_overflow): Now extern.
5353 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
5354 (float-time, Fformat_time_string, Fcurrent_time_string)

5358 (decode_time_components, lisp_seconds_argument): New functions.
5359 (make_time): Now static.
5360 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
5361 Report an error if the time is invalid, rather than having the caller
5364 * fileio.c: Include <stat-time.h>
5365 (Fcopy_file): Copy higher-resolution time stamps.
5366 Prefer to set the time stamp via a file descriptor if that works.
5367 (Fset_file_times, Finsert_file_contents, Fwrite_region)
5368 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
5369 (Fvisited_file_modtime, Fset_visited_file_modtime):
5370 Support higher-resolution time stamps.
5372 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
5374 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
5376 * image.c (prepare_image_for_display, clear_image_cache)
5377 (lookup_image): Port to higer-resolution time stamps.
5379 * keyboard.c (start_polling, bind_polling_period):
5380 Check for time stamp overflow.
5381 (read_char, kbd_buffer_get_event, timer_start_idle)
5382 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
5383 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5384 Port to higher-resolution time stamps. Do not assume time_t is signed.
5385 (decode_timer): New function. Timers are now vectors of length 9,
5386 not 8, to accommodate the picosecond component.
5387 (timer_check_2): Use it.
5389 * nsterm.m (select_timeout, timeval_subtract): Remove.
5390 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5391 as they're a bit more accurate and handle overflow better.
5392 (ns_select): Change prototype to be compatible with pselect.
5393 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5394 * nsterm.h (ns_select): Adjust prototype.
5396 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5397 us-resolution time stamps.
5398 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5400 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5402 * lisp.h (time_overflow): New decl.
5403 (wait_reading_process_output): First arg is now intmax_t, not int,
5404 to accommodate larger waits.
5406 * process.h (struct Lisp_Process.read_output_delay):
5407 Now counts nanoseconds, not microseconds.
5408 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
5410 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
5411 (wait_reading_process_output):
5412 Port to ns-resolution time stamps.
5413 (Faccept_process_output, wait_reading_process_output):
5414 Check for time stamp overflow. Do not assume time_t is signed.
5415 (select_wrapper): Remove; we now use pselect.
5416 (Fprocess_attributes): Now generates ns-resolution time stamps.
5418 * sysdep.c: Include utimens.h. Don't include utime.h
5419 or worry about struct utimbuf; gnulib does that for us now.
5420 (gettimeofday): Remove; gnulib provides a substitute.
5421 (make_timeval): New function.
5422 (set_file_times): Now sets ns-resolution time stamps.
5423 New arg FD; all uses changed.
5424 (time_from_jiffies, ltime_from_jiffies, get_up_time)
5425 (system_process_attributes):
5426 Now returns ns-resolution time stamp. All uses changed.
5427 Check for time stamp overflow.
5429 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5430 provides a substitute now.
5432 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5433 since it guarantees struct timespec.
5434 (EMACS_TIME): Now struct timespec, so that we can support
5435 ns-resolution time stamps.
5436 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5437 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5438 (EMACS_USECS): Remove.
5439 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5440 so multiply the arg by 1000 before storing it.
5441 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
5443 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
5444 Port to ns-resolution time stamps.
5445 (EMACS_TIME_NEG_P): Remove; replaced by....
5446 (EMACS_TIME_SIGN): New macro.
5447 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)

5450 (make_timeval, make_lisp_time, decode_time_components): New decls.
5451 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in

5493 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5494 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,

5546 gets killed during executing of this function (Bug#11665).

5549 run by this hook should not change the current buffer.
5551 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

5917 would mishandle a string argument "Xc" if X was a multibyte
5918 character of length 2: it would truncate after X's first byte
5919 rather than including all of X.
5921 2012-06-06 Chong Yidong <cyd@gnu.org>
5923 * buffer.c (word_wrap): Doc fix.
5925 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>
5927 * xdisp.c (note_mode_line_or_margin_highlight): Pacify gcc -Wall.

5937 binary via PaX flags if the paxctl utility is available.
5938 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5939 Restore PaX flags to their default. (Bug#11398)

5943 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
5946 2012-06-03 Chong Yidong <cyd@gnu.org>
5948 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
5949 (note_mode_line_or_margin_highlight): If there is no help echo,
5950 use mode-line-default-help-echo. Handle the case where the mouse
5951 position is past the end of the mode line string.
5953 * buffer.c (buffer_local_value_1): New function, split from
5954 Fbuffer_local_value; can return Qunbound.
5955 (Fbuffer_local_value): Use it.
5956 (Vmode_line_format): Docstring tweaks.
5958 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5960 * sysdep.c (system_process_attributes): Improve comment.
5962 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
5964 * keyboard.c: Export real-this-command to Elisp.
5965 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
5966 and DEFVAR it. Update all users.
5968 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5970 * minibuf.c (Fassoc_string): Remove duplicate declaration.
5972 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
5973 Convert pctcpu and pctmem to Lisp float properly.
5974 Let the compiler fold better, as 100.0/0x8000 is exact.
5976 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
5978 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
5981 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
5983 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
5985 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
5987 For a 'struct window', replace some Lisp_Object fields to
5988 bitfields where appropriate, remove unused fields.
5989 * window.h (struct window): Remove unused 'last_mark_x' and
5990 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
5991 change it's type from Lisp_Object to bitfield.
5992 Change type of 'force_start', 'optional_new_start',
5993 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
5994 fields from Lisp_Object to bitfield. Adjust users accordingly.
5996 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5998 Pacify gcc -Wdouble-precision when using Xaw.
5999 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
6000 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
6001 Use 'float' consistently, rather than 'float' in most places
6002 and 'double' in a couple of places.
6004 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6006 * xdisp.c (handle_stop): Detect whether we have overlay strings
6007 loaded by testing it->current.overlay_string_index to be
6008 non-negative, instead of checking whether n_overlay_strings is
6009 positive. (Bug#11587)
6011 2012-05-31 Chong Yidong <cyd@gnu.org>
6013 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
6015 * doc.c (Fsubstitute_command_keys): Doc fix.
6017 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6019 * search.c (search_buffer): Remove calls to
6020 r_alloc_inhibit_buffer_relocation, as it is now called by
6021 maybe_unify_char, which was the cause of relocation of buffer text
6024 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6026 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6027 for the duration of call to load_charset, to avoid problems with
6028 callers of maybe_unify_char that access buffer text through C
6031 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6032 decrement the inhibition flag, instead of just setting or
6035 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6037 Remove obsolete '#define static' cruft.
6038 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6039 This #undef was "temporary" in 2000; it is no longer needed
6040 now that '#define static' has gone away.
6041 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6042 (gray_bitmap_bits): Remove; no longer needed.
6043 All uses replaced with definiens.
6044 * xterm.c: Include "bitmaps/gray.xbm".
6046 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6048 Clean up __executable_start, monstartup when --enable-profiling.
6049 The following changes affect the code only when profiling.
6050 * dispnew.c (__executable_start): Rename from safe_bcopy.
6051 Define only on platforms that need it.
6052 * emacs.c: Include <sys/gmon.h> when profiling.
6053 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6054 (__executable_start): Remove decl, since lisp.h does it now.
6055 (safe_bcopy): Remove decl; no longer has that name.
6056 (main): Coalesce #if into single bit of code, for simplicity.
6057 Cast pointers to uintptr_t, since standard libraries want integers
6059 * lisp.h (__executable_start): New decl.
6061 2012-05-31 Glenn Morris <rgm@gnu.org>
6063 * image.c (Fimagemagick_types): Doc fix.
6065 2012-05-30 Jim Meyering <meyering@redhat.com>
6067 * callproc.c (Fcall_process_region): Include directory component
6068 in mkstemp error message (Bug#11586).
6070 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6072 * alloc.c, lisp.h (make_pure_vector): Now static.
6074 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

6079 * data.c (Fdefalias): Purify definition, except for keymaps.
6080 (Qdefun): Move from eval.c.
6081 * lisp.h (Qdefun): Remove.
6082 * lread.c (read1): Tiny simplification.
6084 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
6086 Do not create empty overlays with the evaporate property (Bug#9642).
6087 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6088 Bug#9642, but explicitly check that the buffer the overlay would
6089 be moved to is live and rearrange lines to make sure that errors
6090 will not put the overlay in an inconsistent state.
6091 (Fdelete_overlay): Cosmetics.
6093 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6095 * w32term.c (my_bring_window_to_top): New function.
6096 (x_raise_frame): Use handle returned by DeferWindowPos, which
6097 could be different from the original one.
6098 Call my_bring_window_to_top instead of my_set_foreground_window.
6101 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6102 by calling BringWindowToTop.
6104 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6105 (WM_EMACS_END): Increase by one.
6107 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6109 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6110 This avoids undefined behavior that might cause the eassert
6111 to not catch an out-of-range value.
6113 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6115 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
6116 Update dependencies.
6118 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6120 * bidi.c (bidi_mirror_char): Fix last change.
6122 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
6124 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
6125 when referring to sectname field in printf format.
6127 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
6129 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6130 Only r_alloc_inhibit_buffer_relocation needed to be added;
6131 the others were already declared.
6133 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6134 before checking whether it's out of range. Put the check inside
6136 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6138 2012-05-27 Ken Brown <kbrown@cornell.edu>
6140 * callproc.c (Fcall_process): Restore a line that was accidentally
6141 commented out in the 2011-02-13 change (bug#11547).
6143 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6145 * lisp.h [REL_ALLOC]: Add prototypes for external functions
6146 defined on ralloc.c.
6148 * buffer.c [REL_ALLOC]: Remove prototypes of
6149 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
6150 they are now on lisp.h.
6152 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6154 * search.c (search_buffer): Use it to inhibit relocation of buffer
6155 text while re_search_2 is doing its job, because re_search_2 is
6156 passed C pointers to buffer text. (Bug#11519)
6158 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6161 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6162 state after an additional call to move_it_in_display_line_to, keep
6163 the values of it->max_ascent and it->max_descent found for the
6165 (pos_visible_p): Revert the comparison against bottom_y to what it
6166 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
6169 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6171 Fix coding-related core dumps with gcc -ftrapv.
6172 The code was computing A - B, where A and B are pointers, and B is
6173 random garbage. This can lead to core dumps on platforms that
6174 have special pointer registers, and it also leads to core dumps on
6175 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6176 A - B only when B is initialized properly.
6177 * coding.c (coding_set_source, coding_set_destination): Return void.
6178 (coding_change_source, coding_change_destinations): New functions,
6179 with the old behaviors of coding_set_source and coding_set_destination.
6180 All callers that need an offset changed to use these new functions.
6182 2012-05-26 Glenn Morris <rgm@gnu.org>
6184 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
6186 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6188 Extend mouse support on W32 text-mode console.
6189 * xdisp.c (draw_row_with_mouse_face):
6190 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6192 * w32console.c: Include window.h.
6193 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6195 (initialize_w32_display): Initialize mouse-highlight data.
6197 * w32inevt.c: Include termchar.h and window.h.
6198 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6199 moves, call note_mouse_highlight. If help_echo changed, call
6200 gen_help_event to produce help-echo message in the echo area.
6201 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6204 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6206 * lread.c (read1): Simplify slightly to avoid an overflow warning
6207 with GCC 4.7.0 on x86-64.
6209 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6211 * bidi.c (bidi_mirror_char): Revert last change: an int is
6212 definitely wide enough here.
6214 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
6216 Fix integer width and related bugs (Bug#9874).
6217 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
6218 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
6219 (string_bytes, check_sblock, allocate_string_data):
6220 (compact_small_strings, Fmake_bool_vector, make_string)
6221 (make_unibyte_string, make_multibyte_string)
6222 (make_string_from_bytes, make_specified_string)
6223 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
6224 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
6226 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6227 (allocate_pseudovector):
6228 Use int, not EMACS_INT, where int is wide enough.
6229 (inhibit_garbage_collection, Fgarbage_collect):
6230 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6231 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
6232 int might not be wide enough.
6233 (bidi_cache_search, bidi_cache_find, bidi_init_it)
6234 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6235 (bidi_at_paragraph_end, bidi_find_paragraph_start)
6236 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
6237 (bidi_level_of_next_char, bidi_move_to_visually_next):
6238 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6239 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
6240 (Fkill_buffer, Fset_buffer_major_mode)
6241 (advance_to_char_boundary, Fbuffer_swap_text)
6242 (Fset_buffer_multibyte, overlays_at, overlays_in)
6243 (overlay_touches_p, struct sortvec, record_overlay_string)
6244 (overlay_strings, recenter_overlay_lists)
6245 (adjust_overlays_for_insert, adjust_overlays_for_delete)
6246 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
6247 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
6248 (Foverlay_recenter, last_overlay_modification_hooks_used)
6249 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6250 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6251 (validate_region): Omit unnecessary test for b <= e,
6252 since that's guaranteed by the previous test.
6253 (adjust_overlays_for_delete): Avoid pos + length overflow.
6254 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6255 (report_overlay_modification):
6256 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6257 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
6258 Omit pointer cast, which isn't needed anyway, and doesn't work
6259 after the EMACS_INT -> ptrdiff_t change.
6260 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
6261 * buffer.h: Adjust decls to match defn changes elsewhere.
6262 (struct buffer_text, struct buffer):
6263 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6264 Use EMACS_INT, not int, where int might not be wide enough.
6265 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
6266 not int, to avoid needless 32-bit limit on 64-bit hosts.
6267 (exec_byte_code): Use tighter memory-full test, one that checks
6268 for alloca overflow. Don't compute the address of the object just
6269 before an array, as that's not portable. Use EMACS_INT, not
6270 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
6271 * callint.c (Fcall_interactively):
6272 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6273 * callproc.c (call_process_kill, Fcall_process):
6274 Don't assume pid_t fits into an Emacs fixnum.
6275 (call_process_cleanup, Fcall_process, child_setup):
6276 Don't assume pid_t fits into int.
6277 (call_process_cleanup, Fcall_process, delete_temp_file)
6278 (Fcall_process_region):
6279 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6280 (Fcall_process): Simplify handling of volatile integers.
6281 Use int, not EMACS_INT, where int will do.
6282 * casefiddle.c (casify_object, casify_region, operate_on_word)
6283 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
6284 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6285 (casify_object): Avoid integer overflow when overallocating buffer.
6286 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
6287 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
6288 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
6289 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6290 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6291 integers are now checked earlier. All uses replaced with XINT.
6293 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6294 For CCL_MapSingle, check that content and value are in int range.
6295 (ccl_driver, Fregister_code_conversion_map):
6296 Check that Vcode_version_map_vector is a vector.
6297 (resolve_symbol_ccl_program): Check that vector header is in range.
6298 Always copy the vector, so that we can check its contents reliably
6299 now rather than having to recheck each instruction as it's being
6300 executed. Check that vector words fit in 'int'.
6301 (ccl_get_compiled_code, Fregister_ccl_program)
6302 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6303 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
6304 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
6305 contents are in range.
6306 (Fccl_execute_on_string): Check that status is in range.
6307 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
6308 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
6309 Accept and return EMACS_INT, not int, because callers can pass values
6311 (c_string_width, strwidth, lisp_string_width, chars_in_text)
6312 (multibyte_chars_in_text, parse_str_as_multibyte)
6313 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
6314 (str_as_unibyte, str_to_unibyte, string_count_byte8)
6315 (string_escape_byte8, Fget_byte):
6316 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6317 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
6318 avoid mishandling large integers.
6319 * character.h: Adjust decls to match defn changes elsewhere.
6320 * charset.c (load_charset_map_from_file, find_charsets_in_text)
6321 (Ffind_charset_region):
6322 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6323 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
6324 (load_charset_map_from_vector, Fdefine_charset_internal):
6325 Don't assume fixnum fits in int.
6326 (load_charset_map_from_vector, Fmap_charset_chars):
6327 Remove now-unnecessary CHECK_NATNUMs.
6328 (Fdefine_charset_internal): Check ranges here, more carefully.
6329 Don't rely on undefined behavior with signed left shift overflow.
6330 Don't assume unsigned int fits into fixnum, or that fixnum fits
6331 into unsigned int. Don't require max_code to be a valid fixnum;
6332 that's not true for gb10830 4-byte on a 32-bit host. Allow
6333 invalid_code to be a cons, for the same reason. Require code_offset
6334 to be a character. Avoid int overflow if max_char is close
6336 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
6337 this is intended anyway and avoids some undefined behavior.
6338 (load_charset_map): Pass unsigned, not int, as 2nd arg of
6339 INDEX_TO_CODE_POINT, as that's what it expects.
6340 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
6341 * charset.h (DECODE_CHAR): Return int, not unsigned;
6342 this is what was intended anyway, and it avoids undefined behavior.
6343 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
6344 integer-overflow issues.
6345 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
6346 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
6347 where the argument is EMACS_INT, and this behavior is not intended.
6348 * chartab.c (Fmake_char_table, Fset_char_table_range)
6349 (uniprop_get_decoder, uniprop_get_encoder):
6350 Don't assume fixnum fits in int.
6351 * cmds.c (move_point): New function, that does the gist of
6352 Fforward_char and Fbackward_char, but does so while checking
6353 for integer overflow more accurately.

7064 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
7065 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
7066 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
7067 * s/ms-w32.h (DATA_START):
7068 Move here from removed file m/intel386.h.
7069 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
7070 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
7072 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
7074 Assume C89 or later.
7075 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
7076 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
7078 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
7079 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
7080 * textprop.c, tparam.c (NULL): Remove.
7081 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
7082 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
7083 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
7084 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
7085 * xterm.c (input_signal_count): Assume volatile works.
7087 2012-05-21 Ken Brown <kbrown@cornell.edu>
7089 * xgselect.c (xg_select): Fix first argument in call to 'select'
7092 2012-05-20 Ken Brown <kbrown@cornell.edu>
7094 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
7095 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
7097 2012-05-19 Ken Brown <kbrown@cornell.edu>
7099 * xfns.c (x_in_use): Remove `static' qualifier.
7100 * xterm.h (x_in_use): Declare.
7101 * xgselect.c: Include xterm.h.
7102 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
7103 and `display_arg' (bug#9754).
7105 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
7107 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
7109 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
7110 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
7112 2012-05-18 Eli Zaretskii <eliz@gnu.org>
7114 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
7116 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
7117 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
7119 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
7120 reference to image_cache->refcount.
7121 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
7123 2012-05-17 Juri Linkov <juri@jurta.org>
7125 * search.c (Fword_search_regexp, Fword_search_backward)
7126 (Fword_search_forward, Fword_search_backward_lax)
7127 (Fword_search_forward_lax): Move functions to isearch.el
7128 (bug#10145, bug#11381).
7130 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
7132 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
7134 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
7136 * lread.c (init_obarray): Declare Qt and Qnil as special.
7138 2012-05-14 Glenn Morris <rgm@gnu.org>
7140 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
7141 Put "libexec" before "bin", for the sake of init_callproc_1.
7143 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7145 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
7147 * unexaix.c: Port to more-recent AIX compilers.
7148 (report_error, report_error_1, make_hdr, copy_sym)
7149 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
7150 Make arguments const char *, not char *, to avoid violations of C
7151 standard and to fix some AIX warnings reported by Gilles Pion.
7153 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7155 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
7156 already have overlays loaded.
7157 (handle_single_display_spec): Before returning without displaying
7158 fringe bitmap, synchronize the bidi iterator with the main display
7159 iterator, by calling iterate_out_of_display_property.
7160 (iterate_out_of_display_property): Detect buffer iteration by
7161 testing that it->string is a Lisp string.
7162 (get_next_display_element): When the current object is exhausted,
7163 and there's something on it->stack, call set_iterator_to_next to
7164 proceed with what's on the stack, instead of returning zero.
7165 (set_iterator_to_next): If called at the end of a Lisp string,
7166 proceed to consider_string_end without incrementing string
7167 position. Don't increment display vector index past the end of
7168 the display vector. (Bug#11417)
7169 (pos_visible_p): Don't report a position visible when move_it_to
7170 stopped at the last line of window, which happens to be scanned
7171 backwards by the bidi iteration. (Bug#11464)
7173 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7175 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7176 and right-margin display specs even if the spec is invalid or we
7177 are on a TTY, and thus unable to display on the fringes.
7178 That's because the text with the property will not be displayed anyway,
7179 so we need to signal to the caller that this is a "replacing"
7180 display spec. This fixes display when the spec is invalid or we
7183 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7185 * unexaix.c (make_hdr): Fix typo in prototype.
7186 This bug broke the build on AIX. Problem reported by Gilles Pion.
7188 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
7190 * keyboard.c (kbd_buffer_get_event): Read special events also in
7191 batch mode. (Bug#11415)
7193 2012-05-12 Glenn Morris <rgm@gnu.org>
7195 * ns.mk: Update for ns_appbindir no longer having trailing "/".
7197 2012-05-12 Eli Zaretskii <eliz@gnu.org>
7199 * lisp.mk (lisp): Add newcomment.elc.
7201 2012-05-12 Glenn Morris <rgm@gnu.org>
7203 * Makefile.in (MKDIR_P): New, set by configure.
7204 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
7206 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
7208 Remove unused function hourglass_started.
7209 * dispextern.h (hourglass_started):
7210 * w32fns.c (hourglass_started):
7211 * xdisp.c (hourglass_started): Remove.
7213 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7215 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7216 Update dependencies.
7218 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7220 * xgselect.c (xg_select): Put maxfds+1 into a var.
7221 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
7223 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7225 2012-05-10 Dave Abrahams <dave@boostpro.com>
7227 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7228 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7230 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7232 * dbusbind.c (xd_registered_buses): New internal Lisp object.
7233 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7234 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7235 Initialize xd_registered_buses.
7237 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7239 Untag more efficiently if USE_LSB_TAG.
7240 This is based on a proposal by YAMAMOTO Mitsuharu in
7241 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7242 For an admittedly artificial (nth 8000 longlist) benchmark on
7243 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7244 Emacs's overall text size by 1%.
7245 * lisp.h (XUNTAG): New macro.
7246 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7247 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7248 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7249 * eval.c (Fautoload):
7250 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7251 * frame.h (XFRAME): Use XUNTAG.
7253 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7254 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7255 Remove unportable assumptions about print widths of types like
7257 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7258 intptr_t when converting between pointer and integer, to avoid GCC
7259 warnings about wrong width.
7261 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7263 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7264 stack for each reader_thread, instead of defaulting to 8MB
7265 determined by the linker. This avoids failures in creating
7266 subprocesses on Windows 7, see the discussion in this thread:
7267 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7269 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7271 Fix up display of the *Minibuf-0* buffer in the mini window.
7272 * keyboard.c (read_char): Don't clear the echo area if there's no
7274 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7275 contents of *Minibuf-0*) if there's no message displayed in its stead.
7277 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7279 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7282 2012-05-06 Chong Yidong <cyd@gnu.org>
7284 * lisp.mk (lisp): Update.
7286 2012-05-05 Jim Meyering <meyering@redhat.com>
7288 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7290 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7292 * data.c (PUT_ERROR): New macro.
7293 (syms_of_data): Use it. Add new error type `user-error'.
7294 * undo.c (user_error): New function.
7295 (Fprimitive_undo): Use it.
7296 * print.c (print_error_message): Adjust print style for `user-error'.
7297 * keyboard.c (user_error): New function.
7298 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7300 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7302 Do not limit current-time-string to years 1000..9999.
7303 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7304 (Fcurrent_time_string): Support any year that is supported by the
7305 underlying localtime representation. Don't use asctime, as it
7306 has undefined behavior for years outside the range -999..9999.
7308 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7310 Fix race conditions involving setenv, gmtime, localtime, asctime.
7311 Without this fix, interrupts could mess up code that uses these
7312 nonreentrant functions, since setting TZ invalidates existing
7313 tm_zone or tzname values, and since most of these functions return
7314 pointers to static storage.
7315 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7316 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7317 Grow the critical sections to include not just invoking
7318 localtime/gmtime, but also accessing these functions' results
7319 including their tm_zone values if any, and any related TZ setting.
7320 (format_time_string): Last arg is now struct tm *, not struct tm **,
7321 so that the struct tm is saved in the critical section.
7322 All callers changed. Simplify allocation of initial buffer, partly
7323 motivated by the fact that memory allocation needs to be outside
7324 the critical section.
7326 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7328 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7329 with RESET_INTERVAL.
7331 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7332 Remove duplicated buffer name initialization.
7334 2012-05-02 Jim Meyering <jim@meyering.net>
7336 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7338 * xfns.c (x_window): Use xstrdup (Bug#11375).
7340 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7342 * xdisp.c (pos_visible_p): If already at a newline from the
7343 display string before the 'while' loop, don't walk back the glyphs
7344 from it3.glyph_row. Solves assertion violation when the display
7345 string begins with a newline (egg.el). (Bug#11367)
7347 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7349 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7352 2012-05-01 Glenn Morris <rgm@gnu.org>
7354 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7355 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7356 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7357 All were removed before 23.1.
7359 * dispnew.c: Remove HAVE_LIBNCURSES test;
7360 it is always true on relevant platforms.
7362 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7363 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7365 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
7367 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
7369 * .gdbinit (xpr): Remove checks for no longer existing misc types.
7370 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
7373 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
7375 Do not avoid creating empty evaporating overlays (Bug#9642).
7376 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7377 That is, do not delete an evaporating overlay if it becomes
7378 empty after its bounds are adjusted to fit within its buffer.
7379 This fix caused other problems, and I'm reverting it until we get
7380 to the bottom of them.
7382 2012-04-27 Chong Yidong <cyd@gnu.org>
7384 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7386 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7388 * xdisp.c (pos_visible_p): If the window start position is beyond
7389 ZV, start the display from buffer beginning. Prevents assertion
7390 violation in init_iterator when the minibuffer window is scrolled
7393 * window.c (window_scroll_pixel_based): Likewise.
7395 2012-04-27 Chong Yidong <cyd@gnu.org>
7397 * keymap.c (where_is_internal): Doc fix (Bug#10872).
7399 2012-04-27 Glenn Morris <rgm@gnu.org>
7401 * fileio.c (Fcopy_file, Fset_file_selinux_context):
7402 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
7404 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7406 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
7407 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
7409 2012-04-26 Eli Zaretskii <eliz@gnu.org>
7411 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7412 display element, check also the underlying string or buffer
7413 character. (Bug#11341)
7415 * w32menu.c: Include w32heap.h.
7416 (add_menu_item): If the call to AppendMenuW (via
7417 unicode_append_menu) fails, disable Unicode menus only if we are
7418 running on Windows 9X/Me.
7420 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7422 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
7423 (xgetint): Add missing shift for LSB tags.
7425 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7427 * keyboard.c (read_char): Don't wipe echo area for select window
7428 events: These might get delayed via `mouse-autoselect-window'
7431 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
7433 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
7434 manipulation of :loaded-from data.
7436 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
7438 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
7439 now a cons (bug#11311).
7441 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7443 Do not create empty overlays with the evaporate property (Bug#9642).
7444 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7445 if it becomes empty after its bounds are adjusted to fit within
7446 its buffer. Without this fix, in a nonempty buffer (let ((o
7447 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7448 yields an empty overlay that has the evaporate property, which is
7449 not supposed to happen.
7451 Fix minor GTK3 problems found by static checking.
7452 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7453 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7454 (struct _EmacsFixedClass, emacs_fixed_get_type):
7455 Move decls here from emacsgtkfixed.h, since they needn't be public.
7456 (emacs_fixed_get_type): Now static.
7457 (emacs_fixed_class_init): Omit unused local.
7458 (emacs_fixed_child_type): Remove; unused.

7460 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7461 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
7462 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
7463 (EMACS_FIXED_GET_CLASS): Remove; unused.
7464 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
7466 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
7467 Problem reported by Juanma Barranquero for Windows -Wunused-function.
7469 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7471 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
7472 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
7473 (__malloc_size_t, __malloc_ptrdiff_t):
7474 Remove. All uses removed, replaced by the definiens if needed,
7475 since we can assume C89 or better now.
7476 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
7477 (protect_malloc_state, align, get_contiguous_space)
7478 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
7479 (malloc_atfork_handler_child, malloc_enable_thread)

7484 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
7485 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
7486 Define using prototypes, not old style.
7487 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
7488 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
7489 (align): Don't assume that signed integer overflow wraps around.
7490 Omit unused local var.
7491 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
7492 (_free_internal_nolock, memalign, mallochook, reallochook):
7493 Omit no-longer-needed casts.
7494 (valloc): Use getpagesize, not __getpagesize.
7495 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
7496 (struct hdr): The 'magic' member is now size_t, not unsigned long.
7498 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
7500 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
7502 Move functions from C to Lisp. Make non-blocking method calls
7503 the default. Implement further D-Bus standard interfaces.
7505 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
7506 (QCdbus_request_name_allow_replacement)
7507 (QCdbus_request_name_replace_existing)
7508 (QCdbus_request_name_do_not_queue)

7513 (QCdbus_registered_serial, QCdbus_registered_method)
7514 (QCdbus_registered_signal): New Lisp objects.
7515 (XD_DEBUG_MESSAGE): Use sizeof.

7551 * alloc.c: Handle unusual debugging option combinations.
7552 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
7553 since the two debugging options are incompatible.
7554 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7556 (mem_init, mem_insert, mem_insert_fixup):
7557 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

7589 (print_object): Check for cycles even when print-circle is nil and
7590 print-gensym is t, but only check print_depth if print-circle is nil.
7592 2012-04-20 Chong Yidong <cyd@gnu.org>
7594 * process.c (wait_reading_process_output): If EIO occurs on a pty,

7650 New extern decls, to avoid calling undeclared functions.
7651 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
7652 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
7653 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

7694 Remove definition of GC_MARK_STACK, since the default now works.
7695 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
7696 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
7697 no longer the default.
7698 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
7700 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

7723 2012-04-11 Daniel Colascione <dancol@dancol.org>
7725 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
7726 against is gone. It's better to use vfork now so that when Cygwin
7727 gains a new, working vfork, we use it automatically (bug#10398).
7729 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

7750 being loaded (bug#10424).
7752 2012-04-09 Glenn Morris <rgm@gnu.org>
7754 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
7755 not just in the obarray, before snarfing them. (Bug#11036)

7782 * minibuf.c (Fread_variable): Callers changed.
7784 2012-04-09 Eli Zaretskii <eliz@gnu.org>
7786 * xdisp.c (set_cursor_from_row): If the display string appears in
7787 the buffer at position that is closer to point than the position
7788 after the display string, display the cursor on the first glyph of
7789 the display string. Fixes cursor display when a 'display' text
7790 property immediately follows invisible text. (Bug#11094)
7792 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
7794 composite.c: use 'double' consistently
7795 * composite.c (get_composition_id): Use 'double' consistently
7796 instead of converting 'float' to 'double' and vice versa; this is
7797 easier to understand and avoids a GCC warning.
7799 2012-04-09 Glenn Morris <rgm@gnu.org>
7801 * Makefile.in: Generate leim-list with bootstrap-emacs, in
7802 preparation for dumping it with emacs. (Bug#4789)

7824 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
7825 (mark_memory): Mark Lisp_Objects only if pointers might hide in

7845 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
7846 [!WINDOWSNT]: New macros.
7847 (init_libxml2_functions, libxml2_loaded_p): New functions.
7848 (parse_region): Call fn_xmlCheckVersion instead of using the macro
7849 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
7850 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
7851 Calls xmlCleanupParser only if libxml2 was loaded (or statically
7853 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
7854 Call init_libxml2_functions before calling libxml2 functions.
7855 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
7857 * emacs.c: Don't include libxml/parser.h.

7871 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
7872 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
7873 about subtle differences between FETCH_CHAR* and STRING_CHAR*
7874 macros related to unification of CJK characters. For the details,
7875 see the discussion following the message here:
7876 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
7878 2012-04-04 Chong Yidong <cyd@gnu.org>
7880 * keyboard.c (Vdelayed_warnings_list): Doc fix.

7892 2012-03-31 Eli Zaretskii <eliz@gnu.org>
7894 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
7895 position we get to after a call to move_it_to fails the
7896 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
7897 only if we wind up in a string from display property. (Bug#11063)
7899 * window.c (Fdelete_other_windows_internal): Invalidate the row
7900 and column information about mouse highlight, so that redisplay
7901 restores it after reallocating the glyph matrices. (Bug#7464)
7903 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
7904 string comes from a `display' text property, use the buffer
7905 position of that property as if we actually saw that position in
7907 (move_it_by_lines): Remove the assertion that
7908 "it->current_x == 0 && it->hpos == 0" which can be legitimately
7909 violated when there's a before-string at the beginning of a line.
7912 2012-03-30 Eli Zaretskii <eliz@gnu.org>
7914 * xdisp.c (append_space_for_newline): If the default face was
7915 remapped, use the remapped face for the appended newline.
7916 (extend_face_to_end_of_line): Use the remapped default face for
7917 extending the face to the end of the line.
7918 (display_line): Call extend_face_to_end_of_line when the default
7919 face was remapped. (Bug#11068)
7921 2012-03-29 Eli Zaretskii <eliz@gnu.org>

7943 handle-select-window too (Bug#8996).
7945 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
7947 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.

7952 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
7954 2012-03-24 Eli Zaretskii <eliz@gnu.org>
7956 * s/ms-w32.h (tzname): Include time.h before redirecting to

7967 2012-03-23 Eli Zaretskii <eliz@gnu.org>
7969 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
7970 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
7971 when fetching a multibyte character consumes more bytes than
7972 CHAR_BYTES returns, due to unification of CJK characters in
7973 string_char. (Bug#11073)
7975 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
7977 * process.c (wait_reading_process_output): Handle pty disconnect
7978 by refraining from sending oneself a SIGCHLD (bug#10933).

8001 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
8002 to reflect default non-nil value of redisplay-dont-pause.
8004 2012-03-19 Kenichi Handa <handa@m17n.org>
8006 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
8007 it fit in a valid range (Bug#11003).
8009 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8011 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8012 that is not from display property, accept the row as a "cursor
8013 row" if one of the string's character has a non-nil `cursor'
8014 property. Fixes cursor positioning when there are newlines in
8015 overlay strings, e.g. in icomplete.el. (Bug#11035)
8017 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

8048 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8051 2012-03-03 Glenn Morris <rgm@gnu.org>
8053 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

8066 * buffer.c (buffer-list-update-hook): Doc fix.
8068 2012-02-29 Eli Zaretskii <eliz@gnu.org>

8071 push_it before setting up the iterator for the first overlay
8072 string, even if we have an empty string loaded.
8073 (next_overlay_string): If there's an empty string on the iterator
8074 stack, pop the stack. (Bug#10903)
8076 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8078 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8079 Suggested by Stefan Monnier in
8080 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8081 * alloc.c (widen_to_Lisp_Object): New static function.
8082 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8083 and widening them to Lisp_Objects. This would work even if
8084 USE_LSB_TAG is defined and wide integers are used, which might
8085 happen in a future version of Emacs.
8087 2012-02-25 Chong Yidong <cyd@gnu.org>
8089 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

8103 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
8104 call when setting menu-bar-lines and tool-bar-lines parameters.
8105 (unwind_create_frame_1): New helper function.
8107 * window.c (inhibit_window_configuration_change_hook): New var.
8108 (run_window_configuration_change_hook): Obey it.
8109 (syms_of_window): Initialize it.
8111 2012-02-22 Chong Yidong <cyd@gnu.org>
8113 * xterm.c (x_draw_image_relief): Add missing type check for

8126 when computing $valmask.
8128 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8129 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8130 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8131 It's useless in that case, and it can cause problems on hosts
8132 that allocate halves of EMACS_INT values separately.
8133 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8134 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8135 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8136 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8137 it avoids undefined behavior on hosts where shifting right by more
8138 than the word width has undefined behavior.
8140 2012-02-19 Chong Yidong <cyd@gnu.org>
8142 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
8143 (Funhandled_file_name_directory, Ffile_name_as_directory)

8162 2012-02-15 Chong Yidong <cyd@gnu.org>
8164 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
8165 marked as special. Also, starting docstrings with * is obsolete.
8167 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>

8183 as that creates a dangerous corner case.
8185 * window.c (Fdelete_window_internal): Invalidate the mouse
8186 highlight (Bug#9904).
8188 2012-02-12 Glenn Morris <rgm@gnu.org>

8193 * nsselect.m (Fx_own_selection_internal)
8194 (Fx_disown_selection_internal, Fx_selection_exists_p)
8195 (Fx_selection_owner_p, Fx_get_selection_internal):
8196 Sync docs and argument specs with the xselect.c versions.

8218 2012-02-07 Chong Yidong <cyd@gnu.org>
8220 * buffer.c (Fbuffer_local_variables)
8221 (buffer_lisp_local_variables): Handle unbound vars correctly;
8222 don't let Qunbound leak into Lisp.
8224 2012-02-07 Glenn Morris <rgm@gnu.org>
8226 * image.c (Fimagemagick_types): Doc fix.
8228 * image.c (imagemagick-render-type): Change it from a lisp object

8234 * doc.c (store_function_docstring): Avoid applying docstring of
8235 alias to base function (Bug#2603).

8261 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
8263 Handle overflow when computing char display width (Bug#9496).
8264 * character.c (char_width): Return EMACS_INT, not int.
8265 (char_width, c_string_width): Check for overflow when
8266 computing the width; this is possible now that individual
8267 characters can have unbounded width. Problem introduced
8268 by merge from Emacs 23 on 2012-01-19.
8270 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

8299 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
8300 first 2 arguments are identical. This makes inserting large
8301 output from a subprocess an order of magnitude faster on
8302 MS-Windows, where all sbrk'ed memory is always contiguous.

8408 emacs: fix an auto-save permissions race condition (Bug#10400)
8409 * fileio.c (auto_saving_dir_umask): New static var.
8410 (Fmake_directory_internal): Use it.
8411 (do_auto_save_make_dir): Set it, instead of invoking chmod after
8412 creating the directory. The old code temporarily assigns
8413 too-generous permissions to the directory.
8414 (do_auto_save_eh): Clear it.
8415 (Fdo_auto_save): Catch all errors, not just file errors, so
8416 that the var is always cleared.

8473 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
8474 property that ends at ZV, so that the bidi iteration could be

8921 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
8922 is set, removing the need for VIRT_ADDRESS_VARIES.
8923 (PURE_P): Use a more-efficient implementation that needs just one

8926 to 4 (xorl, subq, cmpq, setbe).

8938 (erase_phys_cursor, update_window_cursor, show_mouse_face)
8939 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
8940 behave as if the cursor position were at the window margin.
8942 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
8943 and the cursor position is out of bounds, behave as if the cursor
8944 position were at the window margin. (Bug#10075)
8946 2011-11-18 Chong Yidong <cyd@gnu.org>
8948 * window.c (Fwindow_combination_limit): Make first argument

8974 * dispnew.c (verify_row_hash): Call row_hash for computing the
8975 hash code of a row, instead of duplicating code from xdisp.c.
8977 * dispextern.h (row_hash): Add prototype.

9196 (Fwindow_vscroll): Doc fix.

9451 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
9453 * w32fns.c (w32_default_color_map): New function,
9454 extracted from Fw32_default_color_map.
9455 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
9457 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
9459 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
9461 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
9463 * keyboard.c (test_undefined): New function (bug#9751).
9464 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
9466 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
9468 * sysdep.c (init_sys_modes): Fix the check for the controlling
9469 terminal (Bug#6649).
9471 2011-10-20 Eli Zaretskii <eliz@gnu.org>
9473 * dispextern.h (struct bidi_it): New member next_en_type.
9475 * bidi.c (bidi_line_init): Initialize the next_en_type member.
9476 (bidi_resolve_explicit_1): When next_en_pos is valid for the
9477 current character, check also for next_en_type being WEAK_EN.
9478 (bidi_resolve_weak): Don't enter the expensive loop if the current
9479 position is before next_en_pos. Record the bidi type of the first
9480 non-ET, non-BN character we find, in addition to its position.
9481 (bidi_level_of_next_char): Invalidate next_en_type when
9482 next_en_pos is over-stepped.
9484 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
9486 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
9487 * editfns.c: Rewrite current-time-zone so that it invokes
9488 the equivalent of (format-time-string "%Z") to get the time zone name.
9489 This fixes a bug when the time zone name contains characters that
9490 need converting from the system time locale to Emacs internal format.
9491 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9492 that patch fixed format-time-string to do the conversion, but
9493 I forgot to fix current-time-zone.
9494 (format_time_string): New function, containing most of
9495 what Fformat_time_string used to contain.
9496 (Fformat_time_string): Rewrite in terms of format_time_string.
9497 This doesn't change this function's behavior.
9498 (current-time-zone): Rewrite to use format_time_string.
9499 This fixes the bug reported by Michael Schierl in
9500 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9501 Jason Rumney's 2007-06-07 change worked around this bug, but
9503 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9505 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9507 * xdisp.c (start_display): If the character at POS is displayed
9508 via a display vector, reset IT->current.dpvec_index to zero.
9509 (try_window_reusing_current_matrix): If a line ends in a display
9510 vector or the next line starts in a display vector, continue
9511 redrawing the window even though the character position of
9512 start_row was reached.
9515 2011-10-18 Chong Yidong <cyd@gnu.org>
9517 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9518 with nobreak-char-display too.
9520 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9522 Fix part 3 of bug#9771.
9523 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9524 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9525 non-neutral characters if the current character is a paragraph
9526 separator (a.k.a. Newline). This avoids running the same
9527 expensive loop twice, once when we consume the preceding newline
9528 and the other time when the line actually needs to be displayed.
9529 Avoid the loop when we see neutrals on the base embedding level
9530 following a character whose directionality is the same as the
9531 paragraph's. This avoids running the expensive loop when a line
9532 ends in a long sequence of neutrals, like control characters.
9533 Add assertion against STRONG_AL type. Slightly rearrange code
9534 that determines the type of a neutral given the first non-neutral
9536 (bidi_level_of_next_char): Set next_en_pos to zero when
9537 invalidating its info.
9539 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9541 * xdisp.c (push_display_prop): Determine whether to record string
9542 or buffer position by IT->string, not by IT->method. Allow
9543 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9544 (move_it_vertically_backward): Don't look for character position
9545 immediately after the newline when in a continuation line.
9548 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9550 * window.c (coordinates_in_window): Rewrite and delabelize
9551 vertical border check. (Bug#5357) (Bug#9618)
9553 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9555 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9556 errors in XSetWindowBorder (bug#9310).
9558 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9560 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9561 avoid crash when xmalloc overrun checking is enabled.
9563 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9565 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9566 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9567 cursor motion with <left> and <right> arrow keys.
9569 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9570 some callers set that themselves.
9572 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9574 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9575 display string and the previous row comes from the same string and
9576 is empty. (Bug#9739) (Bug#9738)
9578 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9580 * doc.c (get_doc_string): Encode file name (bug#9735).
9582 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9584 * bidi.c (bidi_level_of_next_char):
9585 * xdisp.c (get_visually_first_element): Remove old incorrect
9586 comments regarding the Unicode Line Separator character.
9588 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9590 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9592 * alloc.c (Fgc_status): Do not access beyond zombies array
9593 boundary if nzombies > MAX_ZOMBIES.
9594 * alloc.c (dump_zombies): Add missing format specifier.
9596 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9598 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9599 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9601 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9602 Some packages use them to denote characters with modifiers.
9604 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9606 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9607 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9608 matching a pp-number. Rename parameter var to var1.
9610 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9612 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9614 2011-10-08 Glenn Morris <rgm@gnu.org>
9616 * callint.c (Fcall_interactively): Give a more explicit error for the
9617 'c' case with a non-character input. (Bug#8479)
9619 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9621 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9623 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9624 lines that are hscrolled on the left.
9626 * dispnew.c (buffer_posn_from_coords): Account for a possible
9627 presence of header-line. (Bug#4426)
9629 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
9631 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
9632 Don't advertise functionality which we discourage or doesn't work.
9634 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
9636 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
9637 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
9638 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
9639 this makes Emacs dump core during garbage collection on rare
9640 occasions. sizeof is obviously inferior to offsetof here, so
9641 stick with offsetof.
9642 (GC_POINTER_ALIGNMENT): New macro.
9643 (mark_memory): Omit 3rd (offset) arg; caller changed.
9644 Don't assume EMACS_INT alignment is the same as pointer alignment.
9646 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
9648 * keyboard.c (read_key_sequence_remapped): New var.
9649 (read_key_sequence): Compute remapping in the right buffer.
9650 (command_loop_1): Use read_key_sequence's remapping directly.
9652 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
9654 * dired.c (file_name_completion): Don't expand file name.
9655 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
9656 before checking file name handler.
9658 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
9659 they've been requested explicitly (bug#9591).
9661 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
9663 * keymap.c (Fsingle_key_description): Use make_specified_string
9664 instead of build_string to build string from push_key_description.
9667 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9669 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
9670 This fixes a Y2038 bug on 64-bit hosts.
9671 * buffer.c (reset_buffer):
9672 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
9673 (Fclear_buffer_auto_save_failure):
9674 Use 0, not -1, to represent an unset failure time, since time_t
9675 might not be signed.
9677 Remove dependency on glibc malloc internals.
9678 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9679 Move back here from lisp.h, but with their new implementations.
9680 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9681 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
9682 * charset.c (charset_table_init): New static var.
9683 (syms_of_charset): Use it instead of xmalloc. This removes a
9684 dependency on glibc malloc internals. See Eli Zaretskii's comment in
9685 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
9686 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9687 Move back to alloc.c.
9688 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9689 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
9691 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
9693 * nsterm.m (windowDidResize): Call x_set_window_size only when
9694 ns_in_resize is true. Otherwise set pixelwidth/height and
9695 call change_frame_size (Bug#9628).
9697 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9699 Port --enable-checking=all to Fedora 14 x86-64.
9700 * charset.c (syms_of_charset): Also account for glibc malloc's
9701 internal overhead when calculating the initial malloc maximum.
9703 Port --enable-checking=all to Fedora 14 x86.
9704 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9706 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
9707 (overrun_check_realloc, overrun_check_free):
9708 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
9709 That way, xmalloc returns a properly-aligned pointer even if
9710 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
9711 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
9712 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
9713 into account when calculating the initial malloc maximum.
9714 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9715 Move here from alloc.c, so that charset.c can use it too.
9716 Properly align; the old code wasn't right for common 32-bit hosts
9717 when configured with --enable-checking=all.
9718 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9719 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
9721 2011-09-29 Eli Zaretskii <eliz@gnu.org>
9723 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
9726 2011-09-28 Eli Zaretskii <eliz@gnu.org>
9728 * xdisp.c (compute_display_string_end): If there's no display
9729 string at CHARPOS, return -1.
9731 * bidi.c (bidi_fetch_char): When compute_display_string_end
9732 returns a negative value, treat the character as a normal
9733 character not covered by a display string. (Bug#9624)
9735 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
9737 * lread.c (Fread_from_string): Fix typo in docstring.
9739 2011-09-27 Eli Zaretskii <eliz@gnu.org>
9741 * xdisp.c (handle_invisible_prop): If invisible text ends on a
9742 newline, reseat the iterator instead of bidi-iterating there one
9743 character at a time. (Bug#9610)
9744 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
9745 TO_CHARPOS if the bidi iterator is at base embedding level.
9747 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
9749 * lread.c (readevalloop): Use correct code for NBSP.
9750 (read1): Likewise. (Bug#9608)
9752 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
9754 * dbusbind.c (Fdbus_register_signal): When service is not
9755 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
9757 2011-09-25 Glenn Morris <rgm@gnu.org>
9759 * buffer.c (truncate-lines): Doc fix.
9761 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
9763 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
9764 (Fset_window_next_buffers): Doc fix.
9766 2011-09-24 Glenn Morris <rgm@gnu.org>
9768 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
9770 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
9772 Fix minor problems found by static checking.
9773 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
9774 * indent.c (Fvertical_motion): Fix == vs = typo.
9776 2011-09-24 Eli Zaretskii <eliz@gnu.org>
9778 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
9779 Default value is now t. Doc fix.
9781 * indent.c (Fvertical_motion): Compute and apply the overshoot
9782 logic when moving up, not only when moving down. Fix the
9783 confusing name and values of the it_overshoot_expected variable;
9784 logic changes accordingly. (Bug#9254) (Bug#9549)
9786 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
9787 CHARPOS is covered by a display string which includes newlines.
9788 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
9789 is covered by a display string with embedded newlines.
9791 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
9793 * dbusbind.c (Fdbus_register_signal): Add match rule to
9794 Vdbus_registered_objects_table. (Bug#9581)
9795 (Fdbus_register_method, Vdbus_registered_objects_table):
9798 2011-09-24 Jim Meyering <meyering@redhat.com>
9800 do not ignore write error for any output size
9801 The previous change was incomplete.
9802 While it makes emacs --batch detect the vast majority of stdout
9803 write failures, errors were still ignored whenever the output size is
9804 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
9805 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
9806 && echo FAIL: ignored write error
9807 FAIL: ignored write error
9808 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
9809 && echo FAIL: ignored write error
9810 FAIL: ignored write error
9811 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
9813 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
9815 * emacs.c (Fkill_emacs): In noninteractive mode exit
9816 non-successfully if a write error occurred on stdout. (Bug#9574)
9818 2011-09-21 Eli Zaretskii <eliz@gnu.org>
9820 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
9823 * dispextern.h (struct it): Update the comment documenting what
9826 2011-09-20 Eli Zaretskii <eliz@gnu.org>
9828 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
9829 a display string, extend search for cursor position to end of row.
9830 (find_row_edges): If the row ends in a newline from a display
9831 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
9832 Handle the case of a display string with multiple newlines.
9833 (Fcurrent_bidi_paragraph_direction): Fix search for previous
9834 non-empty line. Fixes confusing cursor motion with arrow keys at
9835 the beginning of a line that starts with whitespace.
9837 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9839 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
9842 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
9844 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
9847 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9849 * xdisp.c (display_line): Record maximum and minimum buffer
9850 positions even if no glyphs were produced (e.g., by a zero-width
9851 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
9852 buffer positions that will be removed from the glyph row because
9854 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
9855 column is beyond frame width: don't subtract 1 "pixel" when
9856 computing width of the stretch.
9857 (reseat_at_next_visible_line_start): Undo the change made on
9858 2011-09-17 that saved paragraph information and restored it after
9859 the call to `reseat'. (Bug#9545)
9861 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9863 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
9864 and turn window cursor on if cleared (Bug#9415).
9866 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
9868 * search.c (boyer_moore): Take unibyte characters from pattern
9869 literally. (Bug#9458)
9871 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9873 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
9875 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
9877 Fix minor problem found by static checking.
9878 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
9879 initialized, to pacify gcc -Wuninitialized.
9881 * fileio.c: Report proper errno when syscall falls.
9882 (Finsert_file_contents): Save and restore errno,
9883 so that report_file_error outputs the correct diagnostic.
9884 (Fwrite_region) [CLASH_DETECTION]: Likewise.
9886 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9888 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
9890 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9892 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
9893 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
9895 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9897 * xdisp.c (reseat_at_next_visible_line_start): Keep information
9898 about the current paragraph and restore it after the call to reseat.
9900 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
9901 (bidi_find_paragraph_start): Search back for paragraph beginning
9902 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
9903 (bidi_move_to_visually_next): Only trigger paragraph-related
9904 computations when the last character is a newline or at EOB, not
9905 just any NEUTRAL_B. (Bug#9470)
9907 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
9908 truncated lines if point is covered by a display string. (Bug#9524)
9910 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
9912 * xselect.c: Relax test for outgoing X longs (Bug#9498).
9913 (cons_to_x_long): New function.
9914 (lisp_data_to_selection_data): Use it. Correct the test for
9915 short-versus-long data; it was negated. Break out of vector
9916 loop, for efficiency, when a long datum is discovered.
9918 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
9920 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
9922 2011-09-16 Eli Zaretskii <eliz@gnu.org>
9924 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
9925 GCC PR/17406) by declaring this function with external scope.
9927 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9929 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
9930 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
9932 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
9934 * editfns.c (Fformat): Correctly handle text properties on "%%".
9936 2011-09-15 Eli Zaretskii <eliz@gnu.org>
9938 * xterm.c (x_draw_composite_glyph_string_foreground):
9939 * w32term.c (x_draw_composite_glyph_string_foreground):
9940 * term.c (encode_terminal_code):
9941 * composite.c (composition_update_it, get_composition_id):
9942 * xdisp.c (get_next_display_element)
9943 (fill_composite_glyph_string): Add comments about special meaning
9944 of TAB characters in a composition.
9946 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9948 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
9949 This occurs when processing a multibyte format.
9950 Problem reported by Wolfgang Jenker.
9952 2011-09-15 Johan Bockgård <bojohan@gnu.org>
9954 * xdisp.c (try_cursor_movement): Only check for exact match if
9955 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
9957 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9959 Remove unused external symbols.
9960 * dispextern.h (calc_pixel_width_or_height): Remove decl.
9961 * xdisp.c (calc_pixel_width_or_height): Now static.
9962 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
9963 * indent.c (check_display_width):
9964 * w32term.c: Fix comment to match code.
9965 * xterm.c, xterm.h (x_catching_errors): Remove.
9967 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9969 * xselect.c: Use signed conversions more consistently (Bug#9498).
9970 (selection_data_to_lisp_data): Assume incoming selection data are
9971 signed integers, not unsigned. This is to be consistent with
9972 outgoing selection data, which was modified to use signed integers
9973 in as part of the fix to Bug#9196 in response to Jan D.'s comment
9974 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
9975 expects long, not unsigned long.
9977 2011-09-14 Eli Zaretskii <eliz@gnu.org>
9979 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
9980 computation of loop end. Reported by Johan Bockgård
9983 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
9985 * frame.c (Fother_visible_frames_p): Function deleted.
9987 2011-09-12 Eli Zaretskii <eliz@gnu.org>
9989 * indent.c (compute_motion): Process display vector front to back
9990 rather than the other way around. (Bug#2496)
9992 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
9994 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
9996 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
9998 * minibuf.c (Fread_from_minibuffer): Doc fix.
10000 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10002 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
10003 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
10005 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
10007 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
10008 value for non-existent files.
10010 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10012 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10013 set its "size" to -1. This will set the modtime_size field of
10014 the corresponding buffer to -1, which is what
10015 verify-visited-file-modtime expects for files that do not exist.
10018 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
10020 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10022 * lisp.h: ... from here. push_key_description is no longer
10023 defined in keyboard.c, so its declaration should not be in
10024 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10025 logically belongs with push_key_description.
10027 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10029 * buffer.h: Include <sys/types.h> instead of <time.h>.
10030 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
10031 Problem reported by Herbert J. Skuhra.
10033 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
10035 * xml.c (parse_region): Make the parsing work for
10036 non-comment-starting XML files again (bug#9144).
10038 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
10040 * image.c (gif_load): Fix calculation of bottom and right corner.
10043 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10045 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10046 redisplay in small windows.
10048 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10050 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10052 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10054 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10055 Operate on live windows only.
10057 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10059 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10061 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10063 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10064 only under bidi iteration.
10066 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10068 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10070 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10072 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10073 Without this fix, the command to link temacs failed due to an
10074 undefined symbol __builtin_isnan. This is because
10075 /usr/include/iso/math_c99.h #defines isnan(x) to
10076 __builtin_isnan(x), but the bundled gcc, which identifies itself
10077 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10079 * floatfns.c (isnan): #undef, and then #define to a clone of
10081 (Fisnan): Always define, since it's always available now.
10082 (syms_of_floatfns): Always define isnan at the Lisp level.
10084 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10086 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10088 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10090 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10091 The previous code assumed that file offsets (off_t values) fit in
10092 EMACS_INT variables, which is not true on typical 32-bit hosts.
10093 The code messed up by falsely reporting buffer overflow in cases
10094 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10095 when "big" contains more than 2**29 bytes, even though this
10096 inserts just one byte and does not overflow the buffer.
10097 (Finsert_file_contents): Store file offsets as off_t
10098 values, not as EMACS_INT values. Check for overflow when
10099 converting between EMACS_INT and off_t. When checking for
10100 buffer overflow or for overlap, take the offsets into account.
10101 Don't use EMACS_INT for small values where int suffices.
10102 When checking for overlap, fix a typo: ZV was used where
10103 ZV_BYTE was intended.
10104 (Fwrite_region): Don't assume off_t fits into 'long'.
10105 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10107 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10109 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10111 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10113 sprintf-related integer and memory overflow issues (Bug#9412).
10115 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10116 (esprintf, exprintf, evxprintf): New functions.
10117 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10118 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10119 (modify_event_symbol): Do not assume that the length of
10120 name_alist_or_stem is safe to alloca and fits in int.
10121 (Fexecute_extended_command): Likewise for function name and binding.
10122 (Frecursion_depth): Wrap around reliably on integer overflow.
10123 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10124 since some callers pass EMACS_INT values.
10125 (Fsingle_key_description): Don't crash if symbol name contains more
10126 than MAX_ALLOCA bytes.
10127 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10128 (get_minibuffer): Arg is now EMACS_INT, not int.
10129 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10130 (esprintf, exprintf, evxprintf): New decls.
10131 * window.h (command_loop_level, minibuf_level): Reflect API changes.
10133 * dbusbind.c (signature_cat): New function.
10134 (xd_signature, Fdbus_register_signal):
10135 Do not overrun buffer; instead, report string overflow.
10137 * dispnew.c (add_window_display_history): Don't overrun buffer.
10138 Truncate instead; this is OK since it's just a log.
10140 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10141 even if the time zone offset is outlandishly large.
10142 Don't mishandle offset == INT_MIN.
10144 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10145 when creating daemon; the previous buffer-overflow check was incorrect.
10147 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10148 which has the guts of the old verror function.
10150 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10151 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10153 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10154 (font_unparse_xlfd): Don't blindly alloca long strings.
10155 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10156 fits in int, when using sprintf. Use single snprintf to count
10157 length of string rather than counting it via multiple sprintfs;
10158 that's simpler and more reliable.
10159 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10160 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10161 sprintf, in case result does not fit in int.
10163 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10164 (fontset_from_font): Print it.
10166 * frame.c (tty_frame_count): Now printmax_t, not int.
10167 (make_terminal_frame, set_term_frame_name): Print it.
10168 (x_report_frame_params): In X, window IDs are unsigned long,
10169 not signed long, so print them as unsigned.
10170 (validate_x_resource_name): Check for implausibly long names,
10171 and don't assume name length fits in 'int'.
10172 (x_get_resource_string): Don't blindly alloca invocation name;
10173 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10176 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10177 (xg_check_special_colors, xg_set_geometry):
10178 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10180 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10181 Use esprintf, not sprintf, in case result does not fit in int.
10183 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10184 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10185 it as a large positive number.
10186 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10187 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10189 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10190 in case result does not fit in int.
10192 * print.c (float_to_string): Detect width overflow more reliably.
10193 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10194 buffer overrun. Don't assume list length fits in 'int'. Treat
10195 print length of 0 as 0, not as infinity; to be consistent with other
10196 uses of print length in this function. Don't overflow print length
10197 index. Don't assume hash table size fits in 'long', or that
10198 vectorlike size fits in 'unsigned long'.
10200 * process.c (make_process): Use printmax_t, not int, to format
10201 process-name gensyms.
10203 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10205 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10206 to avoid potential buffer overrun.
10208 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10209 if X resource line is longer than 512 bytes.
10211 * xfns.c (x_window): Make sprintf buffer a bit bigger
10212 to avoid potential buffer overrun.
10214 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10216 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10218 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10220 Integer overflow fixes for scrolling, etc.
10221 Without these, Emacs silently mishandles large integers sometimes.
10222 For example, "C-u 4294967297 M-x recenter" was treated as if
10223 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10225 * xdisp.c (try_window_id): Check Emacs fixnum range before
10226 converting to 'int'.
10228 * window.c (window_scroll_line_based, Frecenter):
10229 Check that an Emacs fixnum is in range before assigning it to 'int'.
10230 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10231 values converted from Emacs fixnums.
10232 (Frecenter): Don't wrap around a line count if it is out of 'int'
10233 range; instead, treat it as an extreme value.
10234 (Fset_window_configuration, compare_window_configurations):
10235 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10237 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10238 that can exceed INT_MAX. Check that EMACS_INT value is in range
10239 before assigning it to the (possibly-narrower) index.
10240 (match_limit): Don't assume that a fixnum can fit in 'int'.
10242 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10245 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10246 (Fvertical_motion): Don't wrap around LINES values that don't fit
10247 in 'int'. Instead, treat them as extreme values. This is good
10248 enough for windows, which can't have more than INT_MAX lines anyway.
10250 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10252 * Require libxml/parser.h to avoid compilation warning.
10254 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10256 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10257 since this reportedly can destroy thread storage.
10259 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10261 * syntax.c (find_defun_start): Update all cache variables if
10262 exiting early (Bug#9401).
10264 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10266 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10268 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10269 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10270 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10272 * term.c (tty_append_glyph): New function.
10273 (produce_stretch_glyph): Static function and its prototype deleted.
10275 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10278 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10280 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10281 when checking :margin (Bug#9390).
10282 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10283 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10284 so that the name doesn't mislead. All uses changed.
10286 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10288 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
10291 2011-08-27 Eli Zaretskii <eliz@gnu.org>
10293 * xdisp.c (move_it_to): Don't bail out early when reaching
10294 position beyond to_charpos, if we are scanning backwards.
10295 (move_it_vertically_backward): When DY == 0, make sure we get to
10296 the first character in the line after the newline.
10298 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10300 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10301 (ccl_driver): Do not generate an out-of-range pointer.
10302 (Fccl_execute_on_string): Remove unnecessary check for
10303 integer overflow, noted by Stefan Monnier in
10304 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10305 Remove a FIXME that didn't need fixing.
10306 Simplify the newly-introduced buffer reallocation code.
10308 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10310 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10312 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10314 Integer and memory overflow issues (Bug#9196).
10316 * doc.c (get_doc_string): Rework so that
10317 get_doc_string_buffer_size is the actual buffer size, rather than
10318 being 1 less than the actual buffer size; this makes xpalloc more
10321 * image.c (x_allocate_bitmap_record, cache_image):
10322 * xselect.c (Fx_register_dnd_atom):
10323 Simplify previous changes by using xpalloc.
10325 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10326 since either will do and ptrdiff_t is convenient with xpalloc.
10328 * charset.c (charset_table_size)
10329 (struct charset_sort_data.priority): Now ptrdiff_t.
10330 (charset_compare): Don't overflow if priorities differ greatly.
10331 (Fsort_charsets): Don't assume list length fits in int.
10332 Check for size-calculation overflow when allocating sort data.
10333 (syms_of_charset): Allocate an initial charset table that is
10334 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10336 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10338 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10339 The actual value is always <= INT_MAX, and leaving it unsigned made
10340 overflow checking harder.
10342 * dispextern.h (struct glyph_matrix.rows_allocated)
10343 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10344 with xpalloc. The values are still always <= INT_MAX.
10346 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10348 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10349 (SAFE_NALLOCA): New macro.
10351 * region-cache.c (struct boundary.pos, find_cache_boundary)
10352 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10353 (set_cache_region, invalidate_region_cache)
10354 (revalidate_region_cache, know_region_cache, region_cache_forward)
10355 (region_cache_backward, pp_cache):
10356 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10357 so that ptrdiff_t * can be passed to xpalloc.
10358 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
10359 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
10360 (pp_cache): Don't assume cache_len fits in int.
10361 * region-cache.h: Adjust extern decls to match.
10363 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
10364 EMACS_INT, since either will do, for xpalloc.
10366 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
10367 (xnmalloc, xnrealloc, xpalloc): New functions.
10369 * bidi.c (bidi_shelve_header_size): New constant.
10370 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
10371 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
10373 * bidi.c (bidi_cache_shrink):
10374 * buffer.c (overlays_at, overlays_in, record_overlay_string)
10376 Don't update size of array until after memory allocation succeeds,
10377 because xmalloc/xrealloc may not return.
10378 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10379 now that we have proper integer overflow checking.

10381 calculating size of overlay_str_buf.
10383 * callproc.c (Fcall_process): Check for size overflow when
10384 calculating size of args2.
10385 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
10386 Normally we prefer signed values, but sticking with ptrdiff_t would
10387 require adding more-complicated checks.
10389 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10390 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
10391 Redo buffer-overflow calculations to avoid integer overflow.

10430 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10432 * emacs.c (main): Do not reallocate argv, since there is a null at
10433 the end that can be overwritten, and this way there's no need to
10434 worry about size-calculation overflow.
10435 (sort_args): Check for size-calculation overflow.
10437 * eval.c (init_eval_once, grow_specpdl): Don't update size until

10443 Check for integer overflow.
10444 (x_set_alpha): Do not assume XINT fits in int.
10446 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10447 This is for the members text_lines, text_cols, total_lines, total_cols,
10448 where the system imposes an 'int' limit.

10457 Check for size-calculation overflow.
10458 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10459 do, as we prefer signed integers.

10466 * gtkutil.h: Change prototypes to match the above.
10468 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

10563 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
10564 (X_LONG_MIN): New macros.
10565 Use them to make the following changes clearer.
10566 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
10567 This change doesn't affect the value now, but it may help remind
10568 future maintainers not to raise the value too much later.
10569 (SELECTION_QUANTUM): Remove, replacing with ...
10570 (selection_quantum): ... new function, which avoids overflow.
10572 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10573 assumption that selection length fits in 'int'.

10590 Don't store size until memory allocation succeeds.
10591 (x_get_window_property): Plug memory leak on memory exhaustion.
10592 Don't double-block input; malloc is safe here. Don't assume 2**34
10593 - 4 fits in unsigned long. Add an xassert to check
10594 XGetWindowProperty overflow. Be more careful about overflow
10595 calculations, and distinguish size from memory overflow better.
10596 (receive_incremental_selection): When tracing, don't assume
10597 unsigned int is less than INT_MAX.
10598 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

10601 in the range -65535 through -1 fit in an X unsigned short.
10602 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10603 result parameters unless successful. Rely on cons_to_unsigned
10604 to report problems with elements; the old code wasn't right anyway.
10605 (x_check_property_data): Check for int overflow; we cannot use
10606 a wider type due to X limits.

10639 * lisp.h (hash_lookup, hash_put):
10640 * minibuf.c (Ftest_completion):
10641 Use ptrdiff_t for hash table indexes, not int (which is too
10642 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
10643 32-bit --with-wide-int hosts).
10645 * charset.c (Fdefine_charset_internal): Check for integer overflow.
10646 Add a FIXME comment about memory leaks.

10654 with outlandish widths.
10655 * character.h (sanitize_tab_width): Rename from sanitize_width,
10656 now that we have two such functions. All uses changed.

10675 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
10676 (x_send_scroll_bar_event): Likewise. Check that the size does not
10677 exceed limits imposed by XClientMessageEvent, as well as the usual
10678 ptrdiff_t and size_t limits.
10680 * keyboard.c: Overflow, signedness and related fixes.
10681 (make_lispy_movement): Use same integer type in forward decl
10682 that is used in the definition.

10684 Change bufsize argument back to int, undoing my 2011-03-30 change.
10685 We prefer signed types, and int is wide enough here.
10686 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
10687 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
10688 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
10689 length, not size_t. Use ptrdiff_t for index, not int.
10690 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
10691 possibility of integer overflow.

10719 Prefer int to unsigned where either will do.
10720 (tiff_handler): New function, combining the cores of the
10721 old tiff_error_handler and tiff_warning_handler.
10722 This function is rewritten to use vsnprintf and thereby avoid
10723 stack buffer overflows. It uses only the features of vsnprintf
10724 that are common to both POSIX and native Microsoft.
10725 (tiff_error_handler, tiff_warning_handler): Use it.
10726 (tiff_load, gif_load, imagemagick_load_image):
10727 Don't assume :index value fits in 'int'.

10730 the integer types that MagickCropImage accepts. Don't assume
10731 Vimagemagick_render_type has a nonnegative value. Don't assume
10732 size_t fits in 'long'.
10733 (gs_load): Use printmax_t to print the widest integers possible.

10747 (handle_single_display_spec): If the display spec is of the form
10748 `(space ...)', and specifies display in the text area, return 2
10750 (try_cursor_movement): Check for the need to scroll more
10751 accurately, and prefer exact match for point under bidi.
10752 Don't advance `row' beyond the last row of the window.

10770 buffers, return left-to-right.
10771 (set_cursor_from_row): Consider candidate row a win if its glyph
10772 represents a newline and point is on that newline. Fixes cursor
10773 positioning on the newline at EOL of R2L text within L2R
10774 paragraph, and vice versa.
10775 (try_cursor_movement): Check continued rows, in addition to
10776 continuation rows. Fixes unwarranted scroll when point enters a
10777 continued line of R2L text within an L2R paragraph, or vice versa.
10778 (cursor_row_p): Consider the case of point being equal to
10779 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
10780 from the end of a short line to the beginning of a continued line
10781 of R2L text within L2R paragraph.
10782 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

10805 * xdisp.c (redisplay_window): When computing centering_position,
10806 account for the height of the header line. (Bug#8874)
10808 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
10809 instead of CHAR_TO_BYTE. Fixes a crash when a completion
10810 candidate is selected by the mouse, and that candidate has a
10811 composed character under the mouse.
10813 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
10814 coordinates reported by pos-visible-in-window-p for a composed
10815 character in column zero.
10817 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

10825 composed buffer positions.
10827 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
10829 * image.c (gif_load): Don't assume that each subimage has the same
10830 dimensions as the base image. Handle disposal method that is
10831 "undefined" by the gif spec (Bug#9335).
10833 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
10835 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

10841 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
10842 from an Org mode buffer to a Speedbar frame.
10844 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
10845 a composition, take its buffer position from IT->cmp_it.charpos.
10846 Fixes cursor positioning at the beginning of a line that begins
10847 with a composed character.
10849 2011-08-18 Eli Zaretskii <eliz@gnu.org>
10851 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
10852 character bidirectional type, use STRONG_L instead. Fixes crashes
10853 in a buffer produced by `describe-categories'.
10855 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
10856 members before the level stack, so they would be saved and
10857 restored when copying iterator state. Fixes incorrect reordering
10858 around TABs covered by display properties.
10860 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
10862 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

10867 (internal_condition_case_2, internal_condition_case_n):
10868 Remove unnecessary aborts (Bug#9081).
10870 2011-08-17 Eli Zaretskii <eliz@gnu.org>
10872 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
10873 has no `load' handler, try opening the file locally. (Bug#9311)
10875 2011-08-16 Ken Brown <kbrown@cornell.edu>
10877 * gmalloc.c: Expand comment.
10879 2011-08-16 Eli Zaretskii <eliz@gnu.org>

10893 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
10895 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
10896 in the static heap.
10897 [CYGWIN] (special_realloc): New function.
10898 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
10899 requests to realloc storage in the static heap.

10928 after the pid of the process is set to -1 (Bug#8162).
10930 2011-08-14 Eli Zaretskii <eliz@gnu.org>
10932 * xdisp.c (move_it_in_display_line_to): Don't invoke
10933 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
10934 ppos_it. Fixes vertical cursor motion when line beginning is
10935 covered by an image. (Bug#9296)
10937 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
10939 * nsterm.h (ns_run_ascript): Declare.
10940 (NSAPP_DATA2_RUNASSCRIPT): Define.
10942 * nsfns.m (as_script, as_result, as_status): New static variables.
10943 (ns_run_ascript): New function.
10944 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
10945 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
10946 the event loop. Get status from as_status (Bug#7276).
10948 * nsterm.m (sendEvent): If event is NSApplicationDefined and
10949 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
10950 the event loop (Bug#7276).
10952 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
10954 * gnutls.c (QCgnutls_bootprop_priority)

10956 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
10957 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
10958 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
10959 (QCgnutls_bootprop_verify_hostname_error)

10975 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
10976 (Fnetwork_interface_list): Allocate in increments of bytes instead
10977 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
10978 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
10980 (struct ifflag_def): notrailers is smart on OSX.
10981 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
10982 Get hardware address with getifaddrs if available.
10984 2011-08-12 Eli Zaretskii <eliz@gnu.org>
10986 * xdisp.c (iterate_out_of_display_property): xassert that
10987 IT->position is set to within IT->object's boundaries. Break from
10988 the loop as soon as EOB is reached; avoids infloops in redisplay
10989 when IT->position is set up wrongly due to some bug.
10990 Set IT->current to match the bidi iterator unconditionally.
10991 (push_display_prop): Allow GET_FROM_STRING as IT->method on
10992 entry. Force push_it to save on the stack the current
10993 buffer/string position, to be restored by pop_it. Fix flags in
10994 the iterator structure wrt the object coming from a display
10995 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
10996 properties. (Bug#9284)
10998 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
11000 * fontset.c (fontset_get_font_group): Add proper type checks.

11013 no-display-properties-and-no-overlays under bidi display.
11014 Set disp_pos in the bidi iterator to avoid searches for display
11015 properties and overlays.
11017 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
11019 * editfns.c (Fset_time_zone_rule): Document relationship with the

11028 restore_point_unwind (Bug#5984).
11030 2011-08-07 Juri Linkov <juri@jurta.org>
11032 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
11033 to show the arg `TIME' instead of `TIMEVAL'.
11035 2011-08-06 Eli Zaretskii <eliz@gnu.org>
11037 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
11038 display property strides EOL and includes a newline, as in
11039 longlines-mode. (Bug#9254)
11040 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
11041 word-wrap under bidirectional display. (Bug#9224)
11043 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
11044 is non-zero, even if the data buffer is NULL. Fixes a crash in
11045 vertical-motion with longlines-mode. (Bug#9254)
11047 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11049 * bidi.c <bidi_cache_total_alloc>: Now static.
11050 (bidi_initialize): Initialize bidi_cache_total_alloc.
11052 * xdisp.c (display_line): Release buffer allocated for shelved bidi
11055 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
11056 amount allocated this far in `bidi_cache_total_alloc'.
11057 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
11058 non-zero, only free the data buffer without restoring the cache
11059 contents. All callers changed.
11061 * dispextern.h (bidi_unshelve_cache): Update prototype.
11063 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
11064 (move_it_in_display_line, move_it_to)
11065 (move_it_vertically_backward, move_it_by_lines): Replace the call
11066 to xfree to an equivalent call to bidi_unshelve_cache.
11067 (move_it_in_display_line_to): Fix logic of returning
11068 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
11070 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11072 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
11073 came from a string character with a `cursor' property. (Bug#9229)
11075 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11077 * Makefile.in (LIB_PTHREAD): New variable.
11078 (LIBES): Add LIB_PTHREAD (Bug#9216).
11080 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
11081 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
11083 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
11085 * regex.c (re_iswctype): Remove some redundant boolean conversions.
11087 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11089 * xterm.c (x_find_topmost_parent): New function.
11090 (x_set_frame_alpha): Find topmost parent window with
11091 x_find_topmost_parent and set the property there also (bug#9181).
11092 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
11094 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>

11105 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
11106 so that it is not optimized away.
11108 * xdisp.c (compute_display_string_pos): Remove unused local.
11110 2011-08-02 Eli Zaretskii <eliz@gnu.org>
11112 Fix slow cursor motion and scrolling in large buffers with
11113 selective display, like Org Mode buffers. (Bug#9218)
11115 * dispextern.h (struct bidi_it): New member disp_prop_p.
11117 * xdisp.c: Remove one-slot cache of display string positions.
11118 (compute_display_string_pos): Accept an additional argument

11120 for a display string or property. If found, set DISP_PROP_P
11123 * bidi.c (bidi_fetch_char): Accept an additional argument
11124 DISP_PROP_P, and pass it to compute_display_string_pos.
11125 Only handle text covered by a display string if DISP_PROP_P is returned
11126 non-zero. All callers of bidi_fetch_char changed.
11128 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
11130 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
11132 2010-12-03 Don March <don@ohspite.net>
11134 * keymap.c (Fdefine_key): Fix non-prefix key error message when
11135 last character M-[char] is translated to ESC [char] (bug#7541).
11137 2011-08-02 Kenichi Handa <handa@m17n.org>
11139 * lisp.h (uniprop_table): Extern it.
11141 * chartab.c (uniprop_table): Make it non-static.
11143 2011-08-01 Eli Zaretskii <eliz@gnu.org>
11145 * xdisp.c (forward_to_next_line_start): Accept additional argument
11146 BIDI_IT_PREV, and store into it the state of the bidi iterator had
11148 (reseat_at_next_visible_line_start): Use the bidi iterator state
11149 returned by forward_to_next_line_start to restore the state of
11150 it->bidi_it after backing up to previous newline. (Bug#9212)
11152 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
11154 * regex.c (re_comp): Protoize.
11155 (re_exec): Fix return type.
11156 (regexec): Fix type of `ret'. (Bug#9203)
11158 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11160 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
11161 This is needed if max-image-size is a floating-point number.
11163 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11165 * print.c (print_object): Print empty symbol as ##.

11171 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
11172 setting frame foreground color (Bug#9175).
11173 (x_set_background_color): Likewise.

11176 contents (Bug#9176).
11177 (EmacsTooltip -init): Remove bezels and add shadows to
11180 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
11181 or scroll bar (Bug#8470).
11183 * nsfont.m (nsfont_open): Remove assignment to voffset and

11187 * nsterm.h (nsfont_info): Remove voffset field.
11189 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11191 Implement strike-through and overline on NextStep (Bug#8863).
11193 * nsfont.m (nsfont_open): Use underline position provided by font,
11194 instead of hard-coded value of 2.
11195 (nsfont_draw): Call ns_draw_text_decoration instead.

11205 2011-07-28 Eli Zaretskii <eliz@gnu.org>
11207 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
11210 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11212 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11213 Without this fix, if a signal arrives just after memory fills up,
11214 'malloc' might be invoked reentrantly.
11216 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11217 In other words, assume that every image size is allowed, on non-X
11218 hosts. This assumption is probably wrong, but it lets Emacs compile.
11220 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11222 * regex.c (re_iswctype): Convert return values to boolean.
11224 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
11226 * xdisp.c (compute_display_string_pos): Don't use cached display
11227 string position if the buffer had its restriction changed.
11230 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11232 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11234 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11236 Integer signedness and overflow and related fixes. (Bug#9079)
11238 * bidi.c: Integer size and overflow fixes.
11239 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
11240 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
11241 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11242 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11243 (bidi_find_other_level_edge):
11244 Use ptrdiff_t instead of EMACS_INT where either will do.
11245 This works better on 32-bit hosts configured --with-wide-int.
11246 (bidi_cache_ensure_space): Check for size-calculation overflow.
11247 Use % rather than repeated addition, for better worst-case speed.
11248 Don't set bidi_cache_size until after xrealloc returns, because it
11250 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11251 (bidi_cache_ensure_space): Also check that the bidi cache size
11252 does not exceed that of the largest Lisp string or buffer. See Eli
11253 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11255 * alloc.c (__malloc_size_t): Remove.
11256 All uses replaced by size_t. See Andreas Schwab's note
11257 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11259 * image.c: Improve checking for integer overflow.
11260 (check_image_size): Assume that f is nonnull, since
11261 it is always nonnull in practice. This is one less thing to
11262 worry about when checking for integer overflow later.
11263 (x_check_image_size): New function, which checks for integer
11264 overflow issues inside X.
11265 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11266 This removes the need for a memory_full check.
11267 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11268 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11269 (xbm_read_bitmap_data): Change locals back to 'int', since
11270 their values must fit in 'int'.
11271 (xpm_load_image, png_load, tiff_load):
11272 Invoke x_create_x_image_and_pixmap earlier,
11273 to avoid much needless work if the image is too large.
11274 (tiff_load): Treat overly large images as if
11275 x_create_x_image_and_pixmap failed, not as malloc failures.
11276 (gs_load): Use x_check_image_size.
11278 * gtkutil.c: Omit integer casts.
11279 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11280 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11282 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11284 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11285 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11286 would wrongly return t on a 64-bit host.
11288 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11289 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11290 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11291 and therefore cause GCC to emit a bogus diagnostic in some cases.
11293 * image.c: Integer signedness and overflow and related fixes.
11294 This is not an exhaustive set of fixes, but it's time to
11295 record what I've got.
11296 (lookup_pixel_color, check_image_size): Remove redundant decls.
11297 (check_image_size): Don't assume that arbitrary EMACS_INT values
11298 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11299 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11300 (tiff_load, imagemagick_load_image):
11301 Check for overflow in size calculations.
11302 (x_create_x_image_and_pixmap): Remove unnecessary test for
11303 xmalloc returning NULL; that can't happen.
11304 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11305 (xpm_color_bucket): Use better integer hashing function.
11306 (xpm_cache_color): Don't possibly over-allocate memory.
11307 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11308 (gif_memory_source):
11309 Use ptrdiff_t, not int or size_t, to record sizes.
11310 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11311 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11312 either works, as we prefer signed integers.
11313 (tiff_read_from_memory, tiff_write_from_memory):
11314 Return tsize_t, not size_t, since that's what the TIFF API wants.
11315 (tiff_read_from_memory): Don't fail simply because the read would
11316 go past EOF; instead, return a short read.
11317 (tiff_load): Omit no-longer-needed casts.
11318 (Fimagemagick_types): Don't assume size fits into 'int'.
11320 Improve hashing quality when configured --with-wide-int.
11321 * fns.c (hash_string): New function, taken from sxhash_string.
11322 Do not discard information about ASCII character case; this
11323 discarding is no longer needed.
11324 (sxhash-string): Use it. Change sig to match it. Caller changed.
11325 * lisp.h: Declare it.
11326 * lread.c (hash_string): Remove, since we now use fns.c's version.
11327 The fns.c version returns a wider integer if --with-wide-int is
11328 specified, so this should help the quality of the hashing a bit.
11330 * emacs.c: Integer overflow minor fix.
11331 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11332 Define only if GNU_LINUX.
11333 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11335 * dispnew.c: Integer signedness and overflow fixes.
11336 Remove unnecessary forward decls, that were a maintenance hassle.
11337 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11339 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11340 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11341 (prepare_desired_row, line_draw_cost):
11342 Use int, not unsigned, where either works.
11343 (save_current_matrix, restore_current_matrix):
11344 Use ptrdiff_t, not size_t, where either works.
11345 (init_display): Check for overflow more accurately, and without
11346 relying on undefined behavior.
11348 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11349 Remove, replacing with the new symbols in lisp.h. All uses changed.
11350 * fileio.c (make_temp_name):
11351 * filelock.c (lock_file_1, lock_file):
11352 * xdisp.c (message_dolog):
11353 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11354 Use pMd etc. instead.
11355 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11356 replacing the pWIDE etc. symbols removed from editfns.c.
11358 * keyboard.h (num_input_events): Now uintmax_t.
11359 This is (very slightly) less likely to mess up due to wraparound.
11362 * buffer.c: Integer signedness fixes.
11363 (alloc_buffer_text, enlarge_buffer_text):
11364 Use ptrdiff_t rather than size_t when either will do, as we prefer
11367 * alloc.c: Integer signedness and overflow fixes.
11368 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11369 (__malloc_size_t): Default to size_t, not to int.
11370 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11371 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11372 Prefer ptrdiff_t to size_t when either would do, as we prefer
11374 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11375 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11376 Now const. Initialize with values that are in range even if char
11378 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11379 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11380 These functions do the right thing with sizes > 2**32.
11381 (check_depth): Now ptrdiff_t, not int.
11382 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11383 Adjust to new way of storing sizes. Check for size overflow bugs
11385 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11386 slightly wrong anyway, as it missed one instance of
11387 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11388 (refill_memory_reserve): Omit needless cast to size_t.
11389 (mark_object_loop_halt): Mark as externally visible.
11391 * xselect.c: Integer signedness and overflow fixes.
11392 (Fx_register_dnd_atom, x_handle_dnd_message):
11393 Use ptrdiff_t, not size_t, since we prefer signed.
11394 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11395 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11396 x_dnd_atoms_size and x_dnd_atoms_length.
11398 * doprnt.c: Prefer signed to unsigned when either works.
11400 * doprnt.c (doprnt):
11402 * xdisp.c (vmessage):
11403 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11404 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11405 prefer signed arithmetic to avoid comparison confusion.
11406 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11407 but is a bit tricky.
11409 Assume freestanding C89 headers, string.h, stdlib.h.
11410 * data.c, doprnt.c, floatfns.c, print.c:
11411 Include float.h unconditionally.
11412 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11413 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11414 * regex.c: Likewise for stddef.h, string.h.
11415 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11416 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11417 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11418 (STDC_HEADERS): Remove obsolete defines.
11419 * sysdep.c: Include limits.h unconditionally.
11421 Assume support for memcmp, memcpy, memmove, memset.
11422 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11423 * regex.c (memcmp, memcpy):
11424 Remove; we assume C89 now.
11426 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11427 (__malloc_safe_bcopy): Remove; no longer needed.
11429 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11430 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11431 well either way, and we prefer signed to unsigned.
11433 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11435 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11436 closes the connection while we're reading (bug#9182).
11438 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11440 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11441 are specified (Bug#9168).
11443 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11445 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11446 Found by GCC static checking and --with-wide-int on a 32-bit host.
11448 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11450 * xdisp.c (compute_display_string_pos): Fix logic of caching
11451 previous display string position. Initialize cached_prev_pos to
11452 -1. Fixes slow-down at the beginning of a buffer.
11454 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11456 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11457 for attrs[LFACE_FONTSET_INDEX].
11459 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11461 * xml.c (parse_region): Remove unused local
11462 that was recently introduced.
11464 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11466 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11467 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11469 * xdisp.c (move_it_in_display_line_to): Record the best matching
11470 position for TO_CHARPOS while scanning the line, and restore it on
11471 exit if none of the characters scanned was an exact match.
11472 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11473 when exact match is impossible due to invisible text, and the
11474 lines are truncated.
11476 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11478 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11481 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11483 Fix a significant slow-down of cursor motion with C-n, C-p,
11484 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11485 auto-repeat under bidi redisplay in fontified buffers.
11486 * xdisp.c (compute_stop_pos_backwards): New function.
11487 (next_element_from_buffer): Call compute_stop_pos_backwards to
11488 find a suitable prev_stop when we find ourselves before
11490 (reseat): Don't look for prev_stop, as that could mean a very long
11492 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11493 <cached_disp_overlay_modiff>: Cache for last found display string
11495 (compute_display_string_pos): Return the cached position if asked
11496 about the same buffer in the same area of character positions, and
11497 the buffer wasn't changed since the time the display string
11498 position was cached.
11500 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11502 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11503 is an integer, which is important for empty lines. (Bug#9149)
11505 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11507 * frame.c (Fmodify_frame_parameters): In tty case, update the
11508 default face if necessary (Bug#4238).
11510 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11512 * editfns.c (Fstring_to_char): No need to explain what a character
11513 is in the docstring (Bug#6576).
11515 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11517 * xml.c (parse_region): Make sure we always return a tree.
11519 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11521 * xml.c (parse_region): If a document contains only comments,
11524 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11526 * xml.c (make_dom): Return comments, too.
11528 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11531 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11532 and the surrounding thread.
11533 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11534 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11535 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11537 * s/openbsd.h (BROKEN_SIGIO): Define.
11538 * unexelf.c (unexec) [__OpenBSD__]:
11539 Don't update the .mdebug section of the Alpha COFF symbol table.
11541 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11543 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11546 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11548 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11549 This fixes some race conditions on the permissions of any newly
11552 * alloc.c (valid_pointer_p): Use pipe, not open.
11553 This fixes some permissions issues when debugging.
11555 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11556 If fchown fails to set both uid and gid, try to set just gid,
11557 as that is sometimes allowed. Adjust the file's mode to eliminate
11558 setuid or setgid bits that are inappropriate if fchown fails.
11560 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11562 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11563 to compare Lisp_Objects.
11564 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11565 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11566 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11568 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11570 * lread.c (read_integer): Unread even EOF character.
11571 (read1): Likewise. Properly record start position of symbol.
11573 * lread.c (read1): Read `#:' as empty uninterned symbol if no
11574 symbol character follows.
11576 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11578 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11579 This works around a problem with the previous change to Fcopy_file.
11580 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11581 and without this change, GCC might complain about discarding
11582 fchown's return value.
11584 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11586 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11588 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11590 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11592 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11594 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11595 it's used from the C level.
11597 * process.c: Use the same condition for POLL_FOR_INPUT in both
11598 keyboard.c and process.c (bug#1858).
11600 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11602 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11603 (Fgnutls_boot): Use it.
11605 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11607 * doc.c (Fsubstitute_command_keys): Revert last change.
11609 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11611 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11612 quotes the next character, and doesn't affect other longer
11613 sequences (bug#8935).
11615 * lread.c (syms_of_lread): Clarify that is isn't only
11616 `eval-buffer' and `eval-defun' that's affected by
11617 `lexical-binding' (bug#8460).
11619 2011-07-15 Eli Zaretskii <eliz@gnu.org>
11621 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11622 bidi redisplay when a line includes both an image and is truncated.
11624 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11626 Fix minor problems found by static checking.
11627 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11628 (elsz): Now a signed constant, not a size_t var. We prefer signed
11629 types to unsigned, to avoid integer comparison confusion. Without
11630 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
11631 "cannot optimize loop, the loop counter may overflow", a symptom
11633 * indent.c (Fvertical_motion): Mark locals as initialized.
11634 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
11636 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
11638 * search.c (Fre_search_backward): Mention `case-fold-search' in
11639 all the re_search_* functions (bug#8138).
11641 * keyboard.c (Fopen_dribble_file): Document when the file is
11644 2011-07-14 Eli Zaretskii <eliz@gnu.org>
11646 * bidi.c (bidi_dump_cached_states): Fix format of displaying
11649 Support bidi reordering of display and overlay strings.
11650 * xdisp.c (compute_display_string_pos)
11651 (compute_display_string_end): Accept additional argument STRING.
11652 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
11653 (reseat_to_string): Initialize bidi_it->string.s and
11654 bidi_it->string.schars.
11655 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
11656 NULL (avoids a crash in bidi_paragraph_init).
11657 Initialize itb.string.lstring.
11658 (init_iterator): Call bidi_init_it only of a valid
11659 buffer position was specified. Initialize paragraph_embedding to
11661 (reseat_to_string): Initialize the bidi iterator.
11662 (display_string): If we need to ignore text properties of
11663 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
11664 original value of -1 will not work with bidi.)
11665 (compute_display_string_pos): First arg is now struct
11666 `text_pos *'; all callers changed. Support display properties on
11668 (compute_display_string_end): Support display properties on Lisp
11670 (init_iterator, reseat_1, reseat_to_string): Initialize the
11671 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
11672 when iterating on a string not from display properties).
11673 (compute_display_string_pos, compute_display_string_end):
11674 Fix calculation of the object to scan. Fixes an error when using
11676 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
11677 base_level_stop; instead, set base_level_stop to BEGV.
11678 Fixes crashes in vertical-motion.
11679 (next_element_from_buffer): Improve commentary for when
11680 the iterator is before prev_stop.
11681 (init_iterator): Initialize bidi_p from the default value of
11682 bidi-display-reordering, not from buffer-local value. Use the
11683 buffer-local value only if initializing for buffer iteration.
11684 (handle_invisible_prop): Support invisible properties on strings
11685 that are being bidi-reordered.
11686 (set_iterator_to_next): Support bidi reordering of C strings and
11688 (next_element_from_string): Support bidi reordering of Lisp
11690 (handle_stop_backwards): Support Lisp strings as well.
11691 (display_string): Support display of R2L glyph rows.
11692 Use IT_STRING_CHARPOS when displaying from a Lisp string.
11693 (init_iterator): Don't initialize it->bidi_p for strings
11695 (reseat_to_string): Initialize it->bidi_p for strings here.
11696 (next_element_from_string, next_element_from_c_string)
11697 (next_element_from_buffer): Add xassert's for correspondence
11698 between IT's object being iterated and it->bidi_it.string
11700 (face_before_or_after_it_pos): Support bidi iteration.
11701 (next_element_from_c_string): Handle the case of the first string
11702 character that is not the first one in the visual order.
11703 (get_visually_first_element): New function, refactored from common
11704 parts of next_element_from_buffer, next_element_from_string, and
11705 next_element_from_c_string.
11706 (tool_bar_lines_needed, redisplay_tool_bar)
11707 (display_menu_bar): Force left-to-right direction. Add a FIXME
11708 comment for making that be controlled by a user option.
11709 (push_it, pop_it): Save and restore the state of the
11710 bidi iterator. Save and restore the bidi_p flag.
11711 (pop_it): Iterate out of display property for string iteration as
11713 (iterate_out_of_display_property): Support iteration over strings.
11714 (handle_single_display_spec): Set up it->bidi_it for iteration
11715 over a display string, and call bidi_init_it.
11716 (handle_single_display_spec, next_overlay_string)
11717 (get_overlay_strings_1, push_display_prop): Set up the bidi

12156 * alloc.c (mark_buffer):
12157 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
12158 (clone_per_buffer_values): Don't assume that
12159 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
12160 This isn't true in general, and it's particularly not true
12161 if Emacs is configured with --with-wide-int.
12162 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
12163 New macros, used in the buffer.c change.

12171 (store_monospaced_changed): Add comment. Call dpyinfo_valid.
12172 (struct xsettings): Move font inside HAVE_XFT.
12173 (GSETTINGS_TOOL_BAR_STYLE, GSETTINGS_FONT_NAME): New defines.
12174 (GSETTINGS_MONO_FONT): Rename from SYSTEM_MONO_FONT.
12175 Move inside HAVE_XFT.
12176 (something_changed_gsettingsCB): Rename from something_changedCB.
12177 Check for changes in GSETTINGS_TOOL_BAR_STYLE and GSETTINGS_FONT_NAME

12183 (parse_settings): Move check for font inside HAVE_XFT.
12184 (read_settings, apply_xft_settings): Add comment.
12185 (read_and_apply_settings): Add comment. Call map_tool_bar_style and
12186 store_tool_bar_style_changed. Move check for font inside HAVE_XFT and
12187 call store_font_name_changed.
12188 (xft_settings_event): Add comment.
12189 (init_gsettings): Add comment. Get values for GSETTINGS_TOOL_BAR_STYLE
12190 and GSETTINGS_FONT_NAME. Move check for fonts within HAVE_XFT.

12197 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
12199 Random fixes. E.g., (random) never returned negative values.
12200 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
12201 subseconds part to the entropy, as that's a bit more random.
12202 Prefer signed to unsigned, since the signedness doesn't matter and
12203 in general we prefer signed. When given a limit, use a
12204 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12205 latter isn't right if USE_2_TAGS_FOR_INTS.
12206 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12207 not 0..VALMASK. Don't discard "excess" bits that random () returns.
12209 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
12211 * textprop.c (text_property_stickiness):
12212 Obey Vtext_property_default_nonsticky.
12213 (syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.
12214 * w32fns.c (syms_of_w32fns):

12217 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
12219 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
12220 This is more efficient than Ffile_directory_p and avoids a minor race.
12222 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
12224 * buffer.c (Foverlay_put): Say what the return value is
12227 * fileio.c (barf_or_query_if_file_exists): Check first if the file
12228 is a directory before asking whether to use the file name
12230 (barf_or_query_if_file_exists): Make the "File is a directory"
12231 error be more correct.
12233 * fns.c (Frequire): Remove the mention of the .gz files, since
12234 that's installation-specific, but keep the mention of
12235 `get-load-suffixes'.
12237 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
12239 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

12244 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
12245 (syms_of_gnutls): Remove duplicate DEFSYM for
12246 Qgnutls_bootprop_verify_hostname_error, an error for
12247 Qgnutls_bootprop_verify_error (which is no longer used).
12249 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
12250 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
12251 Also (re)move comments that are misplaced or no longer relevant.
12253 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12255 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).
12257 2011-07-03 Chong Yidong <cyd@stupidchicken.com>
12259 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
12260 and background color parameters if they have been changed.

12273 2011-07-02 Chong Yidong <cyd@stupidchicken.com>
12275 * keyboard.c (command_loop_1): If a down-mouse event is unbound,
12276 leave any prefix arg for the up event (Bug#1586).

12280 * lread.c (syms_of_lread): Mention single symbols defined by
12281 `defvar' or `defconst' (bug#7154).
12283 * fns.c (Frequire): Mention .el.gz files (bug#7314).
12284 (Frequire): Mention get-load-suffixes.

12314 (syms_of_keymap): Defsubr make-composed-keymap.
12315 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

12352 * eval.c (struct backtrace): Simplify and port the data structure.
12353 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12354 signed bit field, as this assumption is not portable and it makes
12355 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12356 "char debug_on_exit : 1" as this is not portable either; instead,
12357 use the portable "unsigned int debug_on_exit : 1". Remove unused
12358 member evalargs. Remove obsolete comments about cc bombing out.
12360 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

12592 (debug_method_add): Use va_list and vsprintf rather than relying
12593 on undefined behavior with wrong number of arguments.
12594 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12595 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12596 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12597 since we're not interested in debugging glyphs with old libraries.
12598 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12599 GCC 4.6.0's static checking.
12601 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12603 Integer overflow and signedness fixes (Bug#8873).
12604 A few related buffer overrun fixes, too.

12612 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
12613 (x_create_bitmap_from_xpm_data):
12614 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
12615 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
12617 * xfaces.c (load_pixmap):
12618 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
12619 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
12620 (.bitmaps_last, struct x_output.icon_bitmap):
12621 Use ptrdiff_t, not int, for bitmap indexes.
12622 (x_allocate_bitmap_record): Check for size overflow.
12623 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
12625 Use ptrdiff_t, not int, for overlay counts.
12626 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
12627 * editfns.c (overlays_around, get_pos_property):
12628 * textprop.c (get_char_property_and_overlay):
12629 * xdisp.c (next_overlay_change, note_mouse_highlight):
12630 * xfaces.c (face_at_buffer_position):
12631 * buffer.c (OVERLAY_COUNT_MAX): New macro.
12632 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
12633 (Fnext_overlay_change, Fprevious_overlay_change)
12634 (mouse_face_overlay_overlaps, Foverlays_in):
12635 Use ptrdiff_t, not int, for sizes.
12636 (overlays_at, overlays_in): Check for size-calculation overflow.
12638 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
12640 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
12641 (x_session_initialize): Do not assume string length fits in int.
12643 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
12644 This is unlikely, but can occur if DPI is outlandish.
12646 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
12647 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
12649 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
12650 * xrdb.c (magic_file_p, search_magic_path):
12651 Omit last arg SUFFIX; it was always 0. All callers changed.
12652 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
12654 * xfont.c (xfont_match): Avoid need for strlen.
12656 * xfns.c: Don't assume strlen fits in int.
12657 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
12659 * xdisp.c (message_log_check_duplicate): Return intmax_t,
12660 not unsigned long, as we prefer signed integers. All callers changed.
12661 Detect integer overflow in repeat count.
12662 (message_dolog): Don't assume print length fits in 39 bytes.
12663 (display_mode_element): Don't assume strlen fits in int.
12665 * termcap.c: Don't assume sizes fit in int and never overflow.
12666 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
12667 (gobble_line): Check for size-calculation overflow.
12669 * minibuf.c (Fread_buffer):
12670 * lread.c (intern, intern_c_string):
12671 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
12672 Don't assume string length fits in int.
12674 * keyboard.c (parse_tool_bar_item):
12675 * gtkutil.c (style_changed_cb): Avoid need for strlen.
12677 * font.c: Don't assume string length fits in int.
12678 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
12679 Use ptrdiff_t, not int.
12680 (font_intern_prop): Don't assume string length fits in int.
12681 Don't assume integer property fits in fixnum.
12682 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
12684 * filelock.c: Fix some buffer overrun and integer overflow issues.
12685 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
12686 Reformulate so as not to need the command string.
12687 Invoke gzip -cd rather than gunzip, as it's more portable.
12688 (lock_info_type, lock_file_1, lock_file):
12689 Don't assume pid_t and time_t fit in unsigned long.
12690 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
12691 (current_lock_owner): Prefer signed type for sizes.
12692 Use memcpy, not strncpy, where memcpy is what is really wanted.
12693 Don't assume (via atoi) that time_t and pid_t fit in int.
12694 Check for time_t and/or pid_t out of range, e.g., via a network share.
12695 Don't alloca where an auto var works fine.
12697 * fileio.c: Fix some integer overflow issues.
12698 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
12699 Don't assume string length fits in int.
12700 (directory_file_name): Don't assume string length fits in long.
12701 (make_temp_name): Don't assume pid fits in int, or that its print
12702 length is less than 20.
12704 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
12706 * coding.c (make_subsidiaries): Don't assume string length fits in int.
12708 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
12710 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
12711 We prefer signed integers, even for size calculations.
12713 * emacs.c: Don't assume string length fits in 'int'.
12714 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
12715 (main): Don't invoke strlen when not needed.
12717 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
12718 (XD_DEBUG_MESSAGE): Don't waste a byte.
12720 * callproc.c (getenv_internal_1, getenv_internal)
12721 (Fgetenv_internal):
12722 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
12724 * lread.c (invalid_syntax): Omit length argument.
12725 All uses changed. This doesn't fix a bug, but it simplifies the
12726 code away from its former Hollerith-constant appearance, and it's
12727 one less 'int' to worry about when looking at integer-overflow issues.
12728 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
12730 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
12731 This didn't break anything, but it didn't help either.
12732 It's confusing to put a bogus integer in a place where the actual
12733 value does not matter.
12734 (LIST_END_P): Remove unused macro and its bogus comment.
12735 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
12737 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
12738 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
12740 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
12741 We prefer signed types, and the value cannot exceed the EMACS_INT
12742 range anyway (because otherwise the length would not be representable).
12743 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
12744 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
12745 This avoids a GCC warning when WIDE_EMACS_INT.
12747 * indent.c (sane_tab_width): New function.
12748 (current_column, scan_for_column, Findent_to, position_indentation)
12749 (compute_motion): Use it. This is just for clarity.
12750 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
12752 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
12754 * lisp.h (lint_assume): New macro.
12755 * composite.c (composition_gstring_put_cache):
12756 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
12758 * editfns.c, insdel.c:
12759 Omit unnecessary forward decls, to simplify future changes.
12761 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
12763 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
12765 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
12766 Use much-faster test for byte-length change.
12767 Don't assume string byte-length fits in 'int'.
12768 Check that character arg fits in 'int'.
12769 (mapcar1): Declare byte as byte, for clarity.
12771 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
12773 * fns.c (concat): Catch string overflow earlier.
12774 Do not rely on integer wraparound.
12776 * dispextern.h (struct it.overlay_strings_charpos)
12777 (struct it.selective): Now EMACS_INT, not int.
12778 * xdisp.c (forward_to_next_line_start)
12779 (back_to_previous_visible_line_start)
12780 (reseat_at_next_visible_line_start, next_element_from_buffer):
12781 Don't arbitrarily truncate the value of 'selective' to int.
12783 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
12785 * composite.c: Don't truncate sizes to 'int'.
12786 (composition_gstring_p, composition_reseat_it)
12787 (composition_adjust_point): Use EMACS_INT, not int.
12788 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
12789 not EMACS_UINT, for indexes.
12791 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
12793 * buffer.c: Include <verify.h>.
12794 (struct sortvec.priority, struct sortstr.priority):
12795 Now EMACS_INT, not int.
12796 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
12797 (struct sortstr.size, record_overlay_string)
12798 (struct sortstrlist.size, struct sortlist.used):
12799 Don't truncate size to int.
12800 (record_overlay_string): Check for size-calculation overflow.
12801 (init_buffer_once): Check at compile-time, not run-time.
12803 2011-06-22 Jim Meyering <meyering@redhat.com>
12805 Don't leak an XBM-image-sized buffer
12806 * image.c (xbm_load): Free the image buffer after using it.
12808 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
12811 * composite.c (find_automatic_composition): Omit needless 'return 0;'
12812 that Sun C diagnosed.
12813 * fns.c (secure_hash): Fix pointer signedness issue.
12814 * intervals.c (static_offset_intervals): New function.
12815 (offset_intervals): Use it.
12817 2011-06-21 Leo Liu <sdl.web@gmail.com>
12820 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
12823 * fns.c (secure_hash): Rename from crypto_hash_function and change
12824 the first arg to accept symbols.
12825 (Fsecure_hash): New primitive.
12826 (syms_of_fns): New symbols.
12828 2011-06-20 Deniz Dogan <deniz@dogan.se>
12830 * process.c (Fset_process_buffer): Clarify return value in
12833 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
12835 * dispnew.c (add_window_display_history): Use BVAR.
12837 * xdisp.c (debug_method_add): Use BVAR.
12838 (check_window_end, dump_glyph_matrix, dump_glyph)
12839 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
12841 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
12844 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
12845 check till after the cache is created in init_frame_faces.
12847 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
12849 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
12851 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
12853 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
12854 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
12855 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
12857 Improve buffer-overflow checking (Bug#8873).
12858 * fileio.c (Finsert_file_contents):
12859 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
12860 Remove the old (too-loose) buffer overflow checks.
12861 They weren't needed, since make_gap checks for buffer overflow.
12862 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
12863 The old code merely checked for Emacs fixnum overflow, and relied
12864 on undefined (wraparound) behavior. The new code avoids undefined
12865 behavior, and also checks for ptrdiff_t and/or size_t overflow.
12867 * editfns.c (Finsert_char): Don't dump core with very negative counts.
12868 Tune. Don't use wider integers than needed. Don't use alloca.
12869 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
12871 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
12873 * insdel.c, lisp.h (buffer_overflow): New function.
12874 (insert_from_buffer_1, replace_range, replace_range_2):
12875 * insdel.c (make_gap_larger):
12876 * editfns.c (Finsert_char):
12877 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
12879 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
12881 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
12883 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
12885 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
12886 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
12888 * fileio.c: Don't assume EMACS_INT fits in off_t.
12889 (emacs_lseek): New static function.
12890 (Finsert_file_contents, Fwrite_region): Use it.
12891 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
12893 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
12895 * fns.c: Don't overflow int when computing a list length.
12896 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
12897 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
12898 truncation on 64-bit hosts. Check for QUIT every
12899 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
12900 faster and is responsive enough.
12901 (Flength): Report an error instead of overflowing an integer.
12902 (Fsafe_length): Return a float if the value is not representable
12903 as a fixnum. This shouldn't happen except in contrived situations.
12904 (Fnthcdr, Fsort): Don't assume list length fits in int.
12905 (Fcopy_sequence): Don't assume vector length fits in int.
12907 * alloc.c: Check that resized vectors' lengths fit in fixnums.
12908 (header_size, word_size): New constants.
12909 (allocate_vectorlike): Don't check size overflow here.
12910 (allocate_vector): Check it here instead, since this is the only
12911 caller of allocate_vectorlike that could cause overflow.
12912 Check that the new vector's length is representable as a fixnum.
12914 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
12915 The previous code was bogus. For example, next_almost_prime (32)
12916 returned 39, which is undesirable as it is a multiple of 3; and
12917 next_almost_prime (24) returned 25, which is a multiple of 5 so
12918 why was the code bothering to check for multiples of 7?
12920 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
12922 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
12924 Variadic C functions now count arguments with ptrdiff_t.
12925 This partly undoes my 2011-03-30 change, which replaced int with size_t.
12926 Back then I didn't know that the Emacs coding style prefers signed int.
12927 Also, in the meantime I found a few more instances where arguments
12928 were being counted with int, which may truncate counts on 64-bit
12929 machines, or EMACS_INT, which may be unnecessarily wide.
12930 * lisp.h (struct Lisp_Subr.function.aMANY)
12931 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
12932 Arg counts are now ptrdiff_t, not size_t.
12933 All variadic functions and their callers changed accordingly.
12934 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
12935 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
12936 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
12937 * callint.c (Fcall_interactively): Check arg count for overflow,
12938 to avoid potential buffer overrun. Use signed char, not 'int',
12939 for 'varies' array, so that we needn't bother to check its size
12940 calculation for overflow.
12941 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
12942 * eval.c (apply_lambda):
12943 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
12944 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
12945 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
12947 * callint.c (Fcall_interactively): Don't use index var as event count.
12949 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
12950 * mem-limits.h (SIZE): Remove; no longer used.
12952 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
12954 Remove unnecessary casts.
12955 * xterm.c (x_term_init):
12956 * xfns.c (x_set_border_pixel):
12957 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
12958 These aren't needed now that we assume ANSI C.
12960 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
12961 It's more likely to cause problems (due to unsigned overflow)
12964 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
12966 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
12968 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
12970 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
12972 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
12974 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
12976 GLYPH_CODE_FACE returns EMACS_INT, not int.
12977 * dispextern.h (merge_faces):
12978 * xfaces.c (merge_faces):
12979 * xdisp.c (get_next_display_element, next_element_from_display_vector):
12980 Don't assume EMACS_INT fits in int.
12982 * character.h (CHAR_VALID_P): Remove unused parameter.
12983 * fontset.c, lisp.h, xdisp.c: All uses changed.
12985 * editfns.c (Ftranslate_region_internal): Omit redundant test.
12987 * fns.c (concat): Minor tuning based on overflow analysis.
12988 This doesn't fix any bugs. Use int to hold character, instead
12989 of constantly refetching from Emacs object. Use XFASTINT, not
12990 XINT, for value known to be a character. Don't bother comparing
12991 a single byte to 0400, as it's always less.
12993 * floatfns.c (Fexpt):
12994 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
12996 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
12999 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
13001 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
13002 Without this fix, on a 64-bit host (aset S 0 4294967386) would
13003 incorrectly succeed when S was a string, because 4294967386 was
13004 truncated before it was used.
13006 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13007 Otherwise, an out-of-range integer could cause undefined behavior
13010 * composite.c: Use int, not EMACS_INT, for characters.
13011 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13012 EMACS_INT, for values that are known to be in character range.
13013 This doesn't fix any bugs but is the usual style inside Emacs and
13014 may generate better code on 32-bit machines.
13016 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13017 This is for reasons similar to the recent CHAR_STRING fix.
13018 * charset.c (Fencode_char): Check that character arg is actually
13019 a character. Pass an int to ENCODE_CHAR.
13020 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13021 wider than 'int', as a compile-time check to prevent future regressions
13024 * character.c (char_string): Remove unnecessary casts.
13026 Make sure a 64-bit char is never passed to CHAR_STRING.
13027 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13028 by silently ignoring the top 32 bits, allowing some values
13029 that were far too large to be valid characters.
13030 * character.h: Include <verify.h>.
13031 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13032 arguments are no wider than unsigned, as a compile-time check
13033 to prevent future regressions in this area.

13039 Adjust to CHAR_STRING's new requirement.
13040 * editfns.c (Finsert_char, Fsubst_char_in_region):
13041 * fns.c (concat): Check that character args are actually
13042 characters. Without this test, these functions did the wrong
13043 thing with wildly out-of-range values on 64-bit hosts.
13045 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13046 These casts should not be needed on 32-bit hosts, either.
13047 * keyboard.c (read_char):
13048 * lread.c (Fload): Remove casts to unsigned.
13050 * lisp.h (UNSIGNED_CMP): New macro.

13058 * keyboard.c (read_char): Use UNSIGNED_CMP.
13060 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
13061 not to EMACS_INT, to avoid GCC warning.
13063 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13065 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13066 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
13067 isn't needed on 32-bit machines.
13069 * buffer.c (Fgenerate_new_buffer_name):
13070 Use EMACS_INT for count, not int.
13071 (advance_to_char_boundary): Return EMACS_INT, not int.

13090 (total_free_floats, total_floats, total_free_intervals)
13091 (total_intervals, total_strings, total_free_strings):
13092 Now EMACS_INT, not int. All uses changed.
13093 (Fgarbage_collect): Compute overall total using a double, so that
13094 integer overflow is less likely to be a problem. Check for overflow
13095 when converting back to an integer.
13096 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
13097 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
13098 These were 'int' variables that could overflow on 64-bit hosts;
13099 they were never used, so remove them instead of repairing them.
13100 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
13101 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
13102 Previously, this ceilinged at INT_MAX, but that doesn't work on
13104 (allocate_pseudovector): Don't use EMACS_INT when int would do.
13106 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
13107 (allocate_vectorlike): Check for ptrdiff_t overflow.
13108 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13109 when a (possibly-narrower) signed value would do just as well.
13110 We prefer using signed arithmetic, to avoid comparison confusion.
13112 * alloc.c: Catch some string size overflows that we were missing.
13113 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
13114 for convenience in STRING_BYTES_MAX.
13115 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
13116 The definition here is exact; the one in lisp.h was approximate.
13117 (allocate_string_data): Check for string overflow. This catches
13118 some instances we weren't catching before. Also, it catches
13119 size_t overflow on (unusual) hosts where SIZE_MAX <= min
13120 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
13121 and ptrdiff_t and EMACS_INT are both 64 bits.
13123 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
13124 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
13125 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
13127 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
13129 * alloc.c (Fmake_string): Check for out-of-range init.

13702 instead of using explicit *_CHAR codes.
13703 (bidi_resolve_explicit, bidi_resolve_weak):

13712 (bidi_level_of_next_char): Don't try to lookup the cache for the
13713 next/previous character if nothing is cached there yet, or if we
13714 were just reseat()'ed to a new position.
13716 * xdisp.c (set_cursor_from_row): Set start and stop points
13717 according to the row's direction when priming the loop that looks
13718 for the glyph on which to display cursor.
13719 (single_display_spec_intangible_p): Function deleted.
13720 (display_prop_intangible_p): Reimplement to call
13721 handle_display_spec instead of single_display_spec_intangible_p.
13722 Accept 3 additional arguments needed by handle_display_spec.
13723 This fixes incorrect cursor motion across display property with complex
13724 values: lists, `(when COND...)' forms, etc.

13732 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
13733 value of a `display' property is a "replacing spec".
13734 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
13735 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
13736 the display property, but just return a value indicating whether
13737 the display property will replace the characters it covers.
13738 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
13739 frame_window_p members of struct bidi_it.
13740 (compute_display_string_pos, compute_display_string_end):

13765 * gnutls.c: Use Emacs's memory allocators.
13766 Without this change, the gnutls library would invoke malloc etc.
13767 directly, which causes problems on non-SYNC_INPUT hosts, and which
13768 runs afoul of improving memory_full behavior. (Bug#8761)
13769 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
13770 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
13771 xfree instead of the default malloc, realloc, free.
13772 (Fgnutls_boot): No need to check for memory allocation failure,
13773 since xmalloc does that for us.

13796 for hashes and hash indexes, instead of 'unsigned' and 'int'.
13797 * alloc.c (allocate_vectorlike):
13798 Check for overflow in vector size calculations.
13799 * ccl.c (ccl_driver):
13800 Check for overflow when converting EMACS_INT to int.

13802 need to be updated by these changes.
13803 * fns.c (make_hash_table, maybe_resize_hash_table):
13804 Check for integer overflow with large hash tables.
13805 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
13806 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
13807 (SXHASH_REDUCE): New macro.
13808 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
13809 Use it instead of discarding useful hash info with large hash values.
13810 (sxhash_float): New function.
13811 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
13812 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
13813 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
13814 Rewrite to use FIXNUM_BITS, as this simplifies things.
13815 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
13816 Adjust signatures to match updated version of code.
13817 (consing_since_gc): Now EMACS_INT, since a single hash table can
13818 use more than INT_MAX bytes.

13867 Make it possible to run ./temacs.
13869 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
13870 syms_of_callproc does the same thing. Remove test for
13871 "initialized", do it in the caller.

13899 * image.c: Various fixes to ImageMagick code comments.
13900 (Fimagemagick_types): Doc fix.
13902 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
13904 Minor fixes prompted by GCC 4.6.0 warnings.
13906 * xselect.c (converted_selections, conversion_fail_tag): Now static.
13908 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
13909 (x_clipboard_manager_save_all): Move extern decl to ...
13910 * xterm.h: ... here, so that it can be checked for consistency.
13912 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
13914 * xselect.c (x_clipboard_manager_save_frame)
13915 (x_clipboard_manager_save_all): New functions.
13916 (Fx_clipboard_manager_save): Lisp function deleted.
13918 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
13919 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
13921 * xterm.h: Update prototype.
13923 2011-05-28 William Xu <william.xwl@gmail.com>
13925 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
13926 exiting (Bug#8239).
13928 2011-05-28 Jim Meyering <meyering@redhat.com>
13930 Avoid a sign-extension bug in crypto_hash_function.
13931 * fns.c (to_uchar): Define.
13932 (crypto_hash_function): Use it to convert some newly-signed
13933 variables to unsigned, to avoid sign-extension bugs. For example,
13934 without this change, (md5 "truc") would evaluate to
13935 45723a2aff78ff4fff7fff1114760e62 rather than the expected
13936 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
13937 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
13939 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13941 Integer overflow fixes.
13943 * dbusbind.c: Serial number integer overflow fixes.
13944 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
13945 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
13946 to hold a serial number that is too large for a fixnum.
13947 (Fdbus_method_return_internal, Fdbus_method_error_internal):
13948 Check for serial numbers out of range. Decode any serial number
13949 that was so large that it became a float. (Bug#8722)
13951 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
13952 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13953 Use XFASTINT rather than XUINT when numbers are nonnegative.
13954 (xd_append_arg, Fdbus_method_return_internal):
13955 (Fdbus_method_error_internal): Likewise. Also, for unsigned
13956 arguments, check that Lisp number is nonnegative, rather than
13957 silently wrapping negative numbers around. (Bug#8722)
13958 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
13961 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
13963 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
13965 ccl: Add integer overflow checks.
13966 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
13967 (IN_INT_RANGE): New macros.
13968 (ccl_driver): Use them to check for integer overflow when
13969 decoding a CCL program. Many of the new checks are whether XINT (x)
13970 fits in int; it doesn't always, on 64-bit hosts. The new version
13971 doesn't catch all possible integer overflows, but it's an
13972 improvement. (Bug#8719)
13974 * alloc.c (make_event_array): Use XINT, not XUINT.
13975 There's no need for unsigned here.
13977 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
13978 This follows up to the 2011-05-06 change that substituted uintptr_t
13979 for EMACS_INT. This case wasn't caught back then.
13981 Rework Fformat to avoid integer overflow issues.
13982 * editfns.c: Include <float.h> unconditionally, as it's everywhere
13983 now (part of C89). Include <verify.h>.
13984 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
13985 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
13986 (Fformat): Avoid the prepass trying to compute sizes; it was only
13987 approximate and thus did not catch overflow reliably. Instead, walk
13988 through the format just once, formatting and computing sizes as we go,
13989 checking for integer overflow at every step, and allocating a larger
13990 buffer as needed. Keep track separately whether the format is
13991 multibyte. Keep only the most-recently calculated precision, rather
13992 than them all. Record whether each argument has been converted to
13993 string. Use EMACS_INT, not int, for byte and char and arg counts.
13994 Support field widths and precisions larger than INT_MAX. Avoid
13995 sprintf's undefined behavior with conversion specifications such as %#d
13996 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
13997 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
13998 formatting out-of-range floating point numbers with int
13999 formats. (Bug#8668)
14001 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
14003 * data.c: Avoid integer truncation in expressions involving floats.
14004 * data.c: Include <intprops.h>.
14005 (arith_driver): When there's an integer overflow in an expression
14006 involving floating point, convert the integers to floating point
14007 so that the resulting value does not suffer from catastrophic
14008 integer truncation. For example, on a 64-bit host (* 4
14009 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14010 Do not rely on undefined behavior after integer overflow.
14012 merge count_size_as_multibyte, parse_str_to_multibyte
14013 * character.c, character.h (count_size_as_multibyte):
14014 Rename from parse_str_to_multibyte; all uses changed.
14015 Check for integer overflow.
14016 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14017 since it's now a duplicate of the other. This is more of
14018 a character than a buffer op, so better that it's in character.c.
14019 * fns.c, print.c: Adjust to above changes.
14021 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14023 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14025 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14027 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14028 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14029 (x_clipboard_manager_save): Now static.
14030 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14032 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14033 (crypto_hash_function): Now static.
14034 Fix pointer signedness problems. Avoid unnecessary initializations.
14036 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14038 * termhooks.h (Vselection_alist): Make it terminal-local.
14040 * terminal.c (create_terminal): Initialize it.
14042 * xselect.c: Support for clipboard managers.
14043 (Vselection_alist): Move to termhooks.h as terminal-local var.
14044 (LOCAL_SELECTION): New macro.
14045 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14046 (symbol_to_x_atom): Remove gratuitous arg.
14047 (x_handle_selection_request, lisp_data_to_selection_data)
14048 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14049 (x_own_selection, x_get_local_selection, x_convert_selection):
14050 New arg, specifying work frame. Use terminal-local Vselection_alist.
14051 (some_frame_on_display): Delete unused function.
14052 (Fx_own_selection_internal, Fx_get_selection_internal)
14053 (Fx_disown_selection_internal, Fx_selection_owner_p)
14054 (Fx_selection_exists_p): New optional frame arg.
14055 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14056 (x_handle_selection_clear): Don't treat other terminals with the
14057 same keyboard specially. Use the terminal-local Vselection_alist.
14058 (x_clear_frame_selections): Use Frun_hook_with_args.
14060 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14062 * xterm.h: Add support for those atoms.
14064 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14066 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14067 (converted_selections, conversion_fail_tag): New global variables.
14068 (x_selection_request_lisp_error): Free the above.
14069 (x_get_local_selection): Remove unnecessary code.
14070 (x_reply_selection_request): Args changed; handle arbitrary array
14071 of converted selections stored in converted_selections.
14072 Separate the XChangeProperty and SelectionNotify steps.
14073 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14074 (x_convert_selection): New function.
14075 (x_handle_selection_event): Simplify.
14076 (x_get_foreign_selection): Don't ignore incoming requests while
14077 waiting for an answer; this will fail when we implement
14078 SAVE_TARGETS, and seems unnecessary anyway.
14079 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14080 (Vx_sent_selection_functions): Doc fix.
14082 2011-05-26 Leo Liu <sdl.web@gmail.com>
14084 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14086 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14088 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14090 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14091 for fringe update if it has periodic bitmap.
14092 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14093 and fringe_bitmap_periodic_p.
14095 * fringe.c (get_fringe_bitmap_data): New function.
14096 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14097 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14098 row. Mark glyph row for fringe update if periodicity changed.
14100 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14101 for fringe update unless it has periodic bitmap.
14103 2011-05-25 Kenichi Handa <handa@m17n.org>
14105 * xdisp.c (get_next_display_element): Set correct it->face_id for
14106 a static composition.
14108 2011-05-24 Leo Liu <sdl.web@gmail.com>
14111 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
14113 * fns.c (crypto_hash_function, Fsha1): New function.
14114 (Fmd5): Use crypto_hash_function.
14115 (syms_of_fns): Add Ssha1.
14117 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14119 * gnutls.c: Remove unused macros.
14120 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14121 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14122 Remove macros that are defined and never used.
14123 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14125 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14127 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14128 (Fx_get_selection_internal): Minor cleanup.
14129 (Fx_own_selection_internal): Rename arguments for consistency with
14132 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14134 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
14136 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14138 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
14140 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14142 * dispnew.c (scrolling_window): Don't exclude the case that the
14143 last enabled row in the desired matrix touches the bottom boundary.
14145 2011-05-21 Glenn Morris <rgm@gnu.org>
14147 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
14148 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
14149 and add some more files.
14151 2011-05-20 Eli Zaretskii <eliz@gnu.org>
14153 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
14154 report_file_error introduced by the change from 2011-05-07.
14156 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14158 * systime.h (Time): Define only if emacs is defined.
14159 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14160 where the include path doesn't have X11/X.h by default. See
14161 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14163 2011-05-20 Kenichi Handa <handa@m17n.org>
14165 * composite.c (find_automatic_composition): Fix previous change.
14167 2011-05-20 Glenn Morris <rgm@gnu.org>
14169 * lisp.mk: New file, split from Makefile.in.
14170 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14171 (shortlisp): Remove.
14172 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14174 2011-05-19 Glenn Morris <rgm@gnu.org>
14176 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14177 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14178 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14179 (lisp): Set the order to that of loadup.el.
14180 (shortlisp): Make it a copy of $lisp.
14181 (SOME_MACHINE_LISP): Remove.
14182 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14183 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14185 2011-05-18 Kenichi Handa <handa@m17n.org>
14187 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14188 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14189 (find_automatic_composition): Mostly rewrite for efficiency.
14191 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14193 * makefile.w32-in: Update dependencies.
14195 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14197 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14198 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14200 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14202 Fix some integer overflow issues, such as string length overflow.
14204 * insdel.c (count_size_as_multibyte): Check for string overflow.
14206 * character.c (lisp_string_width): Check for string overflow.
14207 Use EMACS_INT, not int, for string indexes and lengths; in
14208 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14209 the resulting string length overflows an EMACS_INT; instead,
14210 report a string overflow if no precision given. When checking for
14211 precision exhaustion, use a check that cannot possibly have
14212 integer overflow. (Bug#8675)
14213 * character.h (lisp_string_width): Adjust to new signature.
14215 * alloc.c (string_overflow): New function.
14216 (Fmake_string): Use it. This doesn't change behavior, but saves
14217 a few bytes and will simplify future changes.
14218 * character.c (string_escape_byte8): Likewise.
14219 * lisp.h (string_overflow): New decl.
14221 Fixups, following up to the user-interface timestamp change.
14222 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14223 for UI timestamps, instead of unsigned long.
14224 * msdos.c (mouse_get_pos): Likewise.
14225 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14226 * w32gui.h (Time): Define by including "systime.h" rather than by
14227 declaring it ourselves. (Bug#8664)
14229 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14230 * image.c (clear_image_cache): Likewise.
14232 * term.c (term_mouse_position): Don't assume time_t wraparound.
14234 Be more systematic about user-interface timestamps.
14235 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14236 and sometimes 'EMACS_UINT', to represent these timestamps.
14237 This change causes it to use 'Time' uniformly, as that's what X uses.
14238 This makes the code easier to follow, and makes it easier to catch
14239 integer overflow bugs such as Bug#8664.
14240 * frame.c (Fmouse_position, Fmouse_pixel_position):
14241 Use Time, not unsigned long, for user-interface timestamps.
14242 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14243 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14244 * keyboard.h (last_event_timestamp): Likewise.
14245 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14246 * menu.h (xmenu_show): Likewise.
14247 * term.c (term_mouse_position): Likewise.
14248 * termhooks.h (struct input_event.timestamp): Likewise.
14249 (struct terminal.mouse_position_hook): Likewise.
14250 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14251 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14252 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14253 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14254 what it was before.
14255 * menu.h, termhooks.h: Include "systime.h", for Time.
14257 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14258 Don't assume that the difference between two unsigned long values
14259 can fit into an integer. At this point, we know button_down_time
14260 <= event->timestamp, so the difference must be nonnegative, so
14261 there's no need to cast the result if double-click-time is
14262 nonnegative, as it should be; check that it's nonnegative, just in
14263 case. This bug is triggered when events are more than 2**31 ms
14264 apart (about 25 days). (Bug#8664)
14266 * xselect.c (last_event_timestamp): Remove duplicate decl.
14267 (x_own_selection): Remove needless cast to unsigned long.
14269 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14270 that always fit in int. Use a sentinel instead of a counter, to
14271 avoid a temp and to allay GCC's concerns about possible int overflow.
14272 * frame.h (struct frame): Use int for menu_bar_items_used
14273 instead of EMACS_INT, since it always fits in int.
14275 * menu.c (grow_menu_items): Check for int overflow.
14277 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14279 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14280 Before, the code was not consistent. These values cannot exceed
14281 2**31 - 1 so there's no need to make them unsigned.
14282 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14283 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14284 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14286 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14288 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14289 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14290 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14291 presumably because the widths might not match.
14293 * window.c (size_window): Avoid needless test at loop start.
14295 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14297 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14299 2011-05-12 Drew Adams <drew.adams@oracle.com>
14301 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14303 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14305 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14306 `width' to `bar_area_x' and `bar_area_width', respectively.
14307 (x_scroll_run): Take account of fringe background extension.
14309 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14310 Rename local vars `left' and `width' to `bar_area_x' and
14311 `bar_area_width', respectively.
14312 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14313 background extension.
14315 2011-05-10 Jim Meyering <meyering@redhat.com>
14317 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14319 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14321 * image.c (Finit_image_library): Return t for built-in image types,
14322 like pbm and xbm. (Bug#8640)
14324 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14326 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14328 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14330 * w32console.c (Fset_screen_color): Doc fix.
14331 (Fget_screen_color): New function.
14332 (syms_of_ntterm): Defsubr it.
14334 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14335 unlink the temporary file if Fcall_process didn't create it in the
14337 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14338 child process will be redirected to a file specified with `:file'.
14339 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14340 cue to call_process_cleanup not to close that handle.
14342 2011-05-07 Ben Key <bkey76@gmail.com>
14344 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14345 one of two shell specific rules, either bootstrap-temacs-CMD or
14346 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14347 to the previous implementation of the bootstrap-temacs rule.
14348 The bootstrap-temacs-CMD rule is similar to the previous
14349 implementation of the bootstrap-temacs rule except that it
14350 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14353 These changes, along with some changes to nt/configure.bat,
14354 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14355 earlier fix to add support for --cflags and --ldflags options
14356 that include quotes so that it works whether make uses cmd or
14359 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14361 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14362 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14364 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14365 a string. Handle both cases.
14366 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14367 (Fdbus_register_method): Use Qinvalid_function.
14369 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14371 * makefile.w32-in: Update dependencies.
14372 (LISP_H): Add inttypes.h and stdin.h.
14373 (PROCESS_H): Add unistd.h.
14375 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14377 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14378 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14380 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14382 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14384 * term.c (vfatal): Remove stray call to va_end.
14385 It's not needed and the C Standard doesn't allow it here anyway.
14387 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14388 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14390 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14393 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14395 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14397 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14399 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14401 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14403 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14404 * charset.c (Fdefine_charset_internal): Don't initialize
14405 charset.code_space[15]. The value was garbage, on hosts with
14406 32-bit int (Bug#8600).
14408 * lread.c (read_integer): Be more consistent with string-to-number.
14409 Use string_to_number to do the actual conversion; this avoids
14410 rounding errors and fixes some other screwups. Without this fix,
14411 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14412 (digit_to_number): Move earlier, for benefit of read_integer.
14413 Return -1 if the digit is out of range for the base, -2 if it is
14414 not a digit in any supported base. (Bug#8602)
14416 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14418 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14419 to match comment at start of function. This also removes a
14420 GCC warning about overflow in a 32+64-bit port.
14422 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14424 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14425 Reported by Stefan Monnier in
14426 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14427 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14428 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14430 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14431 (EMACS_UINTPTR): Likewise, with uintptr_t.
14433 * lisp.h: Prefer 64-bit EMACS_INT if available.
14434 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14435 on 32-bit hosts that have 64-bit int, so that they can access
14437 However, temporarily disable this change unless the temporary
14438 symbol WIDE_EMACS_INT is defined.
14440 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14442 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14443 This removes an assumption that EMACS_INT and long are the same
14444 width as pointers. The assumption is true for Emacs porting targets
14445 now, but we want to make other targets possible.
14446 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14447 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14448 In the rest of the code, change types of integers that hold casted
14449 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14450 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14451 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14452 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14453 No need to cast type when ORing.
14454 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14455 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14456 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14457 assume EMACS_INT is the same width as char *.
14458 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14459 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14460 Remove no-longer-needed casts.
14461 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14462 (xg_tool_bar_help_callback, xg_make_tool_item):
14463 Use EMACS_INTPTR to hold an integer
14464 that will be cast to void *; this can avoid a GCC warning
14465 if EMACS_INT is not the same width as void *.
14466 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14467 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14468 (current_message_1, set_message_1):
14469 Use a local to convert to proper width without a cast.
14470 * xmenu.c (dialog_selection_callback): Likewise.
14472 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14473 Also, don't assume VALBITS / RAND_BITS is less than 5,
14474 and don't rely on undefined behavior when shifting a 1 left into
14476 * lisp.h (get_random): Change signature to match.
14478 * lread.c (hash_string): Use size_t, not int, for hash computation.
14479 Normally we prefer signed values; but hashing is special, because
14480 it's better to use unsigned division on hash table sizes so that
14481 the remainder is nonnegative. Also, size_t is the natural width
14482 for hashing into memory. The previous code used 'int', which doesn't
14483 retain enough info to hash well into very large tables.
14484 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14486 * dbusbind.c: Don't possibly lose pointer info when converting.
14487 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14488 Use XPNTR rather than XHASH, so that the high-order bits of
14489 the pointer aren't lost when converting through void *.
14491 * eval.c (Fautoload): Don't double-shift a pointer.
14493 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14495 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14497 * gnutls.c (DEF_GNUTLS_FN):
14498 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14500 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14502 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14505 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14507 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14508 New version that can reserve upto 2GB of heap space.
14510 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14512 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14514 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14516 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14517 `gnutls_certificate_set_x509_key_file'.
14519 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
14521 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
14522 Update dependencies.
14524 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14526 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14527 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14528 Remove unused parameter `fildes'.
14529 * process.c (read_process_output, send_process): Don't pass it.
14531 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14533 Fix previous change: the library cache is defined in w32.c.
14534 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14535 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14537 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14539 Implement dynamic loading of GnuTLS on Windows.
14541 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14542 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14543 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14546 * gnutls.c (Qgnutls_dll): Define.
14547 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
14548 (gnutls_*): Declare function pointers.
14549 (init_gnutls_functions): New function to initialize function pointers.

14551 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
14552 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14553 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
14554 (emacs_gnutls_write, emacs_gnutls_read)
14555 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14556 (Fgnutls_available_p): New function.
14557 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
14558 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
14559 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
14561 * image.c: Include w32.h.
14562 (Vimage_type_cache): Delete.

14565 (w32_delayed_load): Move to w32.c.
14567 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
14569 * w32.c (QCloaded_from, Vlibrary_cache): Define.
14570 (w32_delayed_load): Move from image.c. When loading a library, record
14571 its filename in the :loaded-from property of the library id.
14572 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
14573 Initialize and staticpro them.
14574 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
14576 * process.c: Include lisp.h before w32.h, not after.
14577 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
14578 instead of gnutls_record_check_pending.
14580 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
14582 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
14584 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
14585 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
14588 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
14590 * xterm.c (x_set_frame_alpha): Do not set property on anything
14591 else than FRAME_X_OUTER_WINDOW (Bug#8608).
14593 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14595 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
14597 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14599 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

14613 * sysdep.c (wait_for_termination_1): Make static.
14614 (wait_for_termination, interruptible_wait_for_termination):
14615 Move after wait_for_termination_1.
14617 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
14619 * sysdep.c (interruptible_wait_for_termination): New function
14620 which is like wait_for_termination, but allows keyboard
14623 * callproc.c (Fcall_process): Add (:file "file") as an option for
14625 (Fcall_process_region): Ditto.
14627 2011-04-30 Eli Zaretskii <eliz@gnu.org>
14629 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
14630 rather than `XVECTOR (FOO)->size'.
14632 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
14633 inttypes.h, as a gnulib replacement is used if it not available in
14636 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14638 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
14639 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
14640 of MOST_POSITIVE_FIXNUM. (Bug#8528)
14642 * coding.c (coding_alloc_by_realloc): Error out if destination
14643 will grow beyond MOST_POSITIVE_FIXNUM.
14644 (decode_coding_emacs_mule): Abort if there isn't enough place in
14645 charbuf for the composition carryover bytes. Reserve an extra
14646 space for up to 2 characters produced in a loop.
14647 (decode_coding_iso_2022): Abort if there isn't enough place in
14648 charbuf for the composition carryover bytes.
14650 2011-04-21 Eli Zaretskii <eliz@gnu.org>

14653 aborting when %lld or %lll format is passed.
14654 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
14655 %llo or %llx format is passed. (Bug#8545)
14657 * window.c (window_scroll_line_based): Use a marker instead of
14658 simple variables to record original value of point. (Bug#7952)
14660 * doprnt.c (doprnt): Fix the case where a multibyte sequence
14661 produced by %s or %c overflows available buffer space. (Bug#8545)
14663 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
14665 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
14666 (SIZE_MAX): Move defn after all includes, as they might #define it.
14668 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14670 * w32.c (init_environment): Warn about defaulting HOME to C:\.

14694 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
14696 * makefile.w32-in: Update dependencies.
14698 2011-04-27 Eli Zaretskii <eliz@gnu.org>
14700 Improve `doprnt' and its usage. (Bug#8545)
14701 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
14702 `format_end'. Remove support for %l as a conversion specifier.
14703 Don't use xrealloc. Improve diagnostics when the %l size modifier
14704 is used. Update the commentary.
14706 * eval.c (verror): Simplify calculation of size_t.
14708 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
14711 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
14713 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
14716 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14718 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
14719 This makes this file independent of the recent pseudovector change.
14721 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
14723 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
14725 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
14726 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
14727 Remove unused local.
14728 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
14730 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
14731 GCC 4.6.0 optimizes based on type-based alias analysis.
14732 For example, if b is of type struct buffer * and v of type struct
14733 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
14734 != &v->size, and therefore "v->size = 1; b->size = 2; return
14735 v->size;" must therefore return 1. This assumption is incorrect
14736 for Emacs, since it type-puns struct Lisp_Vector * with many other
14737 types. To fix this problem, this patch adds a new type struct
14738 vectorlike_header that documents the constraints on layout of vectors
14739 and pseudovectors, and helps optimizing compilers not get fooled
14740 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
14741 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
14742 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
14744 (XSETPVECTYPE): Rewrite in terms of new macro.
14745 (XSETPVECTYPESIZE): New macro, specifying both type and size.
14746 This is a bit clearer, and further avoids the possibility of
14747 undesirable aliasing.
14748 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
14749 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
14750 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
14751 since Lisp_Subr is a special case (no "next" field).
14752 (ASIZE): Now uses header.size rather than size.
14753 All previous uses of XVECTOR (foo)->size replaced to use this macro,
14754 to avoid the hassle of writing XVECTOR (foo)->header.size.
14755 (struct vectorlike_header): New type.
14756 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
14757 object, to help avoid aliasing.
14758 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
14759 (SUBRP): Likewise, since Lisp_Subr is a special case.
14760 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
14761 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
14762 (struct Lisp_Hash_Table): Combine first two members into a single
14763 struct vectorlike_header member. All uses of "size" and "next" members
14764 changed to be "header.size" and "header.next".
14765 * buffer.h (struct buffer): Likewise.
14766 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
14767 * frame.h (struct frame): Likewise.
14768 * process.h (struct Lisp_Process): Likewise.
14769 * termhooks.h (struct terminal): Likewise.
14770 * window.c (struct save_window_data, struct saved_window): Likewise.
14771 * window.h (struct window): Likewise.
14772 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
14773 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
14774 * buffer.c (init_buffer_once): Likewise.
14775 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
14777 * process.c (Fformat_network_address): Use local var for size,
14780 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
14782 Make the Lisp reader and string-to-float more consistent (Bug#8525)
14783 * data.c (atof): Remove decl; no longer used or needed.
14784 (digit_to_number): Move to lread.c.
14785 (Fstring_to_number): Use new string_to_number function, to be
14786 consistent with how the Lisp reader treats infinities and NaNs.
14787 Do not assume that floating-point numbers represent EMACS_INT
14788 without losing information; this is not true on most 64-bit hosts.
14789 Avoid double-rounding errors, by insisting on integers when
14790 parsing non-base-10 numbers, as the documentation specifies.
14791 * lisp.h (string_to_number): New decl, replacing ...
14792 (isfloat_string): Remove.
14793 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
14794 (read1): Do not accept +. and -. as integers; this
14795 appears to have been a coding error. Similarly, do not accept
14796 strings like +-1e0 as floating point numbers. Do not report
14797 overflow for integer overflows unless the base is not 10 which
14798 means we have no simple and reliable way to continue.
14799 Break out the floating-point parsing into a new
14800 function string_to_number, so that Fstring_to_number parses
14801 floating point numbers consistently with the Lisp reader.
14802 (digit_to_number): Move here from data.c. Make it static inline.
14803 (E_CHAR, EXP_INT): Remove, replacing with ...
14804 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
14805 (string_to_number): New function, replacing isfloat_string.
14806 This function checks for valid syntax and produces the resulting
14807 Lisp float number too. Rework it so that string-to-number
14808 no longer mishandles examples like "1.0e+". Use strtoumax,
14809 so that overflow for non-base-10 numbers is reported only when
14810 there's no portable and simple way to convert to floating point.
14812 * textprop.c (set_text_properties_1): Rewrite for clarity,
14813 and to avoid GCC warning about integer overflow.
14815 * intervals.h (struct interval): Use EMACS_INT for members
14816 where EMACS_UINT might cause problems. See
14817 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
14818 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
14819 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
14821 (offset_intervals): Tell GCC not to worry about length overflow
14822 when negating a negative length.
14824 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
14825 (overrun_check_free): Likewise.
14827 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
14828 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
14831 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14832 (gnutls_make_error): Rename local to avoid shadowing.
14833 (gnutls_emacs_global_deinit): ifdef out; not used.
14834 (Fgnutls_boot): Use const for pointer to readonly storage.
14835 Comment out unused local. Fix pointer signedness problems.
14837 * lread.c (openp): Don't stuff size_t into an 'int'.
14838 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
14839 about possible signed overflow.
14841 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14842 (GDK_KEY_g): Don't define if already defined.
14843 (xg_prepare_tooltip): Avoid pointer signedness problem.
14844 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
14846 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
14847 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
14849 * xfns.c (Fx_window_property): Simplify a bit,
14850 to make a bit faster and to avoid GCC 4.6.0 warning.
14851 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
14853 * fns.c (internal_equal): Don't assume size_t fits in int.
14855 * alloc.c (compact_small_strings): Tighten assertion a little.
14857 Replace pEd with more-general pI, and fix some printf arg casts.
14858 * lisp.h (pI): New macro, generalizing old pEd macro to other
14859 conversion specifiers. For example, use "...%"pI"d..." rather
14860 than "...%"pEd"...".
14861 (pEd): Remove. All uses replaced with similar uses of pI.
14862 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
14863 * alloc.c (check_pure_size): Don't overflow by converting size to int.
14864 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
14865 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
14866 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
14867 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
14868 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
14870 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
14871 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
14872 * print.c (safe_debug_print, print_object): Likewise.
14873 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
14875 Use pI instead of if-then-else-abort. Use %p to avoid casts,
14876 avoiding the 0 flag, which is not portable.
14877 * process.c (Fmake_network_process): Use pI to avoid cast.
14878 * region-cache.c (pp_cache): Likewise.
14879 * xdisp.c (decode_mode_spec): Likewise.
14880 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
14881 behavior on 64-bit hosts with printf arg.
14882 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
14883 (x_stop_queuing_selection_requests): Likewise.
14884 (x_get_window_property): Don't truncate byte count to an 'int'
14887 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
14888 here, since it parses constructs like leading '-' and spaces,
14889 which are not wanted; and it overflows with large numbers.
14890 Instead, simply match F[0-9]+, which is what is wanted anyway.
14892 * alloc.c: Remove unportable assumptions about struct layout.
14893 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
14894 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
14895 (allocate_vectorlike, make_pure_vector): Use the new macros,
14896 plus offsetof, to remove unportable assumptions about struct layout.
14897 These assumptions hold on all porting targets that I know of, but
14898 they are not guaranteed, they're easy to remove, and removing them
14899 makes further changes easier.
14901 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
14902 This doesn't fix a bug but makes the code clearer.
14903 (string_overrun_cookie): Now const. Use initializers that
14904 don't formally overflow signed char, to avoid warnings.
14905 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
14906 can cause Emacs to crash when string overrun checking is enabled.
14907 (allocate_buffer): Don't assume sizeof (struct buffer) is a
14908 multiple of sizeof (EMACS_INT); it need not be, if
14909 alignof(EMACS_INT) < sizeof (EMACS_INT).
14910 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
14912 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

14919 supposed to be handshaking. (Bug#8556)
14920 Reported by Paul Eggert <eggert@cs.ucla.edu>.
14922 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

14933 (check_string_free_list): Convert to standard C.
14935 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
14937 * w32.c (emacs_gnutls_push): Fix typo.
14939 2011-04-25 Eli Zaretskii <eliz@gnu.org>
14941 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
14942 "cast to pointer from integer of different size".
14944 Improve doprnt and its use in verror. (Bug#8545)
14945 * doprnt.c (doprnt): Document the set of format control sequences
14946 supported by the function. Use SAFE_ALLOCA instead of always
14949 * eval.c (verror): Don't limit the buffer size at size_max-1, that
14950 is one byte too soon. Don't use xrealloc; instead xfree and
14953 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
14955 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
14958 * gnutls.c: Renamed global_initialized to
14959 gnutls_global_initialized. Added internals for the
14960 :verify-hostname-error, :verify-error, and :verify-flags
14961 parameters of `gnutls-boot' and documented those parameters in the
14962 docstring. Start callback support.
14963 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
14964 unless a fatal error occurred. Call gnutls_alert_send_appropriate
14965 on error. Return error code.

15025 changes in globals.h immediately force recompilation.
15026 (TAGS): Depend on $(CURDIR)/m/intel386.h and
15027 $(CURDIR)/s/ms-w32.h.

15037 * doprnt.c: Include limits.h.
15038 (SIZE_MAX): New macro.
15039 (doprnt): Return a size_t value. 2nd arg is now size_t.
15040 Many local variables are now size_t instead of int or unsigned.
15041 Improve overflow protection. Support `l' modifier for integer
15042 conversions. Support %l conversion. Don't assume an EMACS_INT
15043 argument for integer conversions and for %c.
15045 * lisp.h (doprnt): Restore prototype.
15047 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
15048 $(SRC)/character.h.
15050 * Makefile.in (base_obj): Add back doprnt.o.
15052 * deps.mk (doprnt.o): Add back prerequisites.
15053 (callint.o): Depend on character.h.
15055 * eval.c (internal_lisp_condition_case): Include the handler
15056 representation in the error message.
15057 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
15058 when breaking from the loop.
15060 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
15062 * callint.c (Fcall_interactively): When displaying error message
15063 about invalid control letter, pass the character's codepoint, not
15064 a pointer to its multibyte form. Improve display of the character
15065 in octal and display also its hex code.
15067 * character.c (char_string): Use %x to display the (unsigned)
15068 codepoint of an invalid character, to avoid displaying a bogus
15071 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15072 `error', not SYMBOL_NAME itself.
15074 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
15075 character arguments to `error'.
15077 * charset.c (check_iso_charset_parameter): Fix incorrect argument
15078 to `error' in error message about FINAL_CHAR argument. Make sure
15079 FINAL_CHAR is a character, and use %c when it is passed as

15144 Define only if needed.
15146 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
15147 by pacifying GCC about it. Maybe it's time to retire it?
15148 * xfaces.c (USG, __TIMEVAL__): Likewise.
15150 * dispextern.h (struct redisplay_interface): Rename param
15151 to avoid shadowing.
15152 * termhooks.h (struct terminal): Likewise.
15153 * xterm.c (xembed_send_message): Likewise.
15155 * insdel.c (make_gap_smaller): Define only if
15156 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
15158 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
15161 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
15162 so that we aren't warned about unused symbols.
15164 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
15166 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

15173 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
15174 (x_dispatch_event): Declare static if USE_GTK, and
15175 define if USE_GTK || USE_X_TOOLKIT.
15176 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
15177 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
15178 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
15179 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
15181 * xmenu.c (menu_help_callback): Pointer type fixes.
15182 Use const pointers when pointing at readonly data. Avoid pointer

15199 compatible char. Avoid the old compiler warnings about
15200 out-of-range initializers by using, for example, '\xab' rather
15203 * xgselect.c (xgselect_initialize): Check vs interface
15204 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

15273 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
15274 --enable-checking=xmallocoverrun). xfree is now used to
15275 deallocate these memory blocks.

15653 (message_enable_multibyte): Remove decl.
15654 (free_misc, interval_free_list, float_block, float_block_index):
15655 (n_float_blocks, float_free_list, cons_block, cons_block_index):
15656 (cons_free_list, last_marked_index):
15658 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
15659 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
15660 (mark_backtrace): Define only if BYTE_MARK_STACK.
15661 * xdisp.c (message_enable_multibyte): Now static.
15663 Declare Lisp_Object Q* variables to be 'static' if not exported.
15664 This makes it easier for human readers (and static analyzers)
15665 to see whether these variables are used from other modules.
15666 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
15667 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
15668 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
15669 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
15670 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
15671 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
15672 * xmenu.c, xselect.c:
15673 Declare Q* vars static if they are not used in other modules.
15674 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
15675 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
15676 Remove decls of unexported vars.
15677 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
15679 * lisp.h (DEFINE_FUNC): Make sname 'static'.
15681 Make Emacs functions such as Fatom 'static' by default.
15682 This makes it easier for human readers (and static analyzers)
15683 to see whether these functions can be called from other modules.
15684 DEFUN now defines a static function. To make the function external
15685 so that it can be used in other C modules, use the new macro DEFUE.
15686 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
15687 (Finit_image_library):
15688 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
15689 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
15690 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
15691 Remove decls, since these functions are now static.
15692 (Funintern, Fget_internal_run_time): New decls, since these functions
15693 were already external.
15695 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
15696 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
15697 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
15698 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
15699 * keyboard.c, keymap.c, lread.c:
15700 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
15701 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
15702 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
15703 Mark functions with DEFUE instead of DEFUN,
15704 if they are used in other modules.
15705 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
15706 decls for now-static functions.
15707 * buffer.h (Fdelete_overlay): Remove decl.
15708 * callproc.c (Fgetenv_internal): Mark as internal.
15709 * composite.c (Fremove_list_of_text_properties): Remove decl.

15712 * dired.c (Ffile_attributes): New forward static decl.
15713 * doc.c (Fdocumntation_property): New forward static decl.
15714 * eval.c (Ffetch_bytecode): New forward static decl.
15715 (Funintern): Remove extern decl; now in .h file where it belongs.
15716 * fileio.c (Fmake_symbolic_link): New forward static decl.
15717 * image.c (Finit_image_library): New forward static decl.
15718 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
15719 * intervals.h (Fprevious_property_change):
15720 (Fremove_list_of_text_properties): Remove decls.
15721 * keyboard.c (Fthis_command_keys): Remove decl.
15722 (Fcommand_execute): New forward static decl.
15723 * keymap.c (Flookup_key): New forward static decl.
15724 (Fcopy_keymap): Now static.
15725 * keymap.h (Flookup_key): Remove decl.
15726 * process.c (Fget_process): New forward static decl.
15727 (Fprocess_datagram_address): Mark as internal.
15728 * syntax.c (Fsyntax_table_p): New forward static decl.
15729 (skip_chars): Remove duplicate decl.
15730 * textprop.c (Fprevious_property_change): New forward static decl.
15731 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
15733 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
15734 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
15736 * editfns.c (Fformat): Remove unreachable code.
15738 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
15740 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
15743 2011-04-13 Eli Zaretskii <eliz@gnu.org>
15745 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
15746 when at ZV. (Bug#8487)
15748 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
15750 * charset.c (Fclear_charset_maps): Use xfree instead of free.
15752 * keyboard.c (parse_tool_bar_item): Likewise.
15753 * sound.c (sound_cleanup, alsa_close): Likewise.
15754 * termcap.c (tgetent): Likewise.
15755 * xfns.c (x_default_font_parameter): Likewise.
15756 * xsettings.c (read_and_apply_settings): Likewise.
15758 * alloc.c (overrun_check_malloc, overrun_check_realloc)
15759 (overrun_check_free): Protoize.
15761 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
15763 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
15764 since callers should never pass a negative size.
15765 Change the signature to match that of plain 'read' and 'write'; see
15766 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
15767 * lisp.h: Update prototypes of emacs_write and emacs_read.
15769 2011-04-11 Eli Zaretskii <eliz@gnu.org>
15771 * xdisp.c (redisplay_window): Don't try to determine the character
15772 position of the scroll margin if the window start point w->startp
15773 is outside the buffer's accessible region. (Bug#8468)
15775 2011-04-10 Eli Zaretskii <eliz@gnu.org>
15777 Fix write-region and its subroutines for buffers > 2GB.
15778 * fileio.c (a_write, e_write): Modify declaration of arguments and
15779 local variables to support buffers larger than 2GB.
15780 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
15782 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
15783 argument, local variables, and return value.
15785 * lisp.h: Update prototypes of emacs_write and emacs_read.
15787 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
15789 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
15791 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
15793 Fix more problems found by GCC 4.6.0's static checks.
15795 * xdisp.c (vmessage): Use a better test for character truncation.
15797 * charset.c (load_charset_map): <, not <=, for optimization,
15798 and to avoid potential problems with integer overflow.
15799 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
15800 * casetab.c (set_identity, shuffle): Likewise.
15801 * editfns.c (Fformat): Likewise.
15802 * syntax.c (skip_chars): Likewise.
15804 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
15805 This also lets GCC 4.6.0 generate slightly better loop code.
15807 * callint.c (Fcall_interactively): <, not <=, for optimization.
15808 (Fcall_interactively): Count the number of arguments produced,
15809 not the number of arguments given. This is simpler and lets GCC
15810 4.6.0 generate slightly better code.
15812 * ftfont.c: Distingish more carefully between FcChar8 and char.
15813 The previous code passed unsigned char * to a functions like
15814 strlen and xstrcasecmp that expect char *, which does not
15815 conform to the C standard.
15816 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
15817 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
15818 char * when the C standard requires it.
15820 * keyboard.c (read_char): Remove unused var.
15822 * eval.c: Port to Windows vsnprintf (Bug#8435).
15823 Include <limits.h>.
15824 (SIZE_MAX): Define if the headers do not.
15825 (verror): Do not give up if vsnprintf returns a negative count.
15826 Instead, grow the buffer. This ports to Windows vsnprintf, which
15827 does not conform to C99. Problem reported by Eli Zaretskii.
15828 Also, simplify the allocation scheme, by avoiding the need for
15829 calling realloc, and removing the ALLOCATED variable.
15831 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
15833 Remove invocations of doprnt, as Emacs now uses vsnprintf.
15834 But keep the doprint source code for now, as we might revamp it
15835 and use it again (Bug#8435).
15836 * lisp.h (doprnt): Remove.
15837 * Makefile.in (base_obj): Remove doprnt.o.
15838 * deps.mk (doprnt.o): Remove.
15840 error: Print 32- and 64-bit integers portably (Bug#8435).
15841 Without this change, on typical 64-bit hosts error ("...%d...", N)
15842 was used to print both 32- and 64-bit integers N, which relied on
15843 undefined behavior.
15844 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
15845 * lisp.h (error, verror): Mark as printf-like functions.
15846 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
15847 Report overflow in size calculations when allocating printf buffer.
15848 Do not truncate output string at its first null byte.
15849 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
15850 Truncate the output at a character boundary, since vsnprintf does not
15852 * charset.c (check_iso_charset_parameter): Convert internal
15853 character to string before calling 'error', since %c now has the
15855 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
15856 overflow when computing char to be passed to 'error'. Do not
15857 pass Lisp_Object to 'error'; pass the integer instead.
15858 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
15859 formatted with plain %d.
15861 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
15863 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
15865 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
15867 * xterm.c (x_catch_errors): Remove duplicate declaration.
15869 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
15871 * xdisp.c, lisp.h (message_nolog): Remove; unused.
15873 2011-04-10 Jim Meyering <meyering@redhat.com>
15875 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
15876 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
15877 return ssize_t not "int", and use size_t as the buffer length.
15878 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
15879 * gnutls.h: Update declarations.
15880 * process.c (read_process_output): Use ssize_t, to match.
15881 (send_process): Likewise.
15883 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15885 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
15887 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15889 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
15890 Use unsigned char, to match FcChar8 type definition.
15892 * xterm.c (handle_one_xevent):
15893 * xmenu.c (create_and_show_popup_menu):
15894 * xselect.c (x_decline_selection_request)
15895 (x_reply_selection_request): Avoid type-punned deref of X events.
15897 2011-04-09 Eli Zaretskii <eliz@gnu.org>
15899 Fix some uses of `int' instead of EMACS_INT.
15900 * search.c (string_match_1, fast_string_match)
15901 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
15902 (scan_buffer, find_next_newline_no_quit)
15903 (find_before_next_newline, search_command, Freplace_match)
15904 (Fmatch_data): Make some `int' variables be EMACS_INT.
15906 * xdisp.c (display_count_lines): 3rd argument and return value now
15907 EMACS_INT. All callers changed.
15908 (pint2hrstr): Last argument is now EMACS_INT.
15910 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
15911 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
15912 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
15913 (decode_coding_utf_16, decode_coding_emacs_mule)
15914 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
15915 (decode_coding_ccl, decode_coding_charset)
15916 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
15917 (decode_coding_iso_2022, decode_coding_emacs_mule)
15918 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
15919 <char_offset, last_offset>: Declare EMACS_INT.
15920 (encode_coding_utf_8, encode_coding_utf_16)
15921 (encode_coding_emacs_mule, encode_invocation_designation)
15922 (encode_designation_at_bol, encode_coding_iso_2022)
15923 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
15924 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
15926 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
15927 (encode_invocation_designation): Last argument P_NCHARS is now
15929 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
15930 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
15932 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
15935 * ccl.c (Fccl_execute_on_string): Declare some variables
15938 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
15940 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
15942 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
15944 * process.c (Fformat_network_address): Doc fix.
15946 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
15948 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
15950 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
15952 * keyboard.c (read_char): Call Lisp function help-form-show,
15953 instead of using internal_with_output_to_temp_buffer.
15954 (Qhelp_form_show): New var.
15955 (syms_of_keyboard): Use DEFSYM macro.
15957 * print.c (internal_with_output_to_temp_buffer): Function deleted.
15959 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
15961 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
15963 * process.c (Flist_processes): Remove to Lisp.
15964 (list_processes_1): Delete.
15966 2011-04-06 Eli Zaretskii <eliz@gnu.org>
15968 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
15970 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
15972 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
15974 Fix more problems found by GCC 4.6.0's static checks.
15976 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
15978 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
15980 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
15982 * xdisp.c (vmessage): Mark as a printf-like function.
15984 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
15986 * sound.c (sound_warning): Don't crash if arg contains a printf format.
15988 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
15989 printf-like functions.

15991 to system-supplied API.
15993 * eval.c (Fsignal): Remove excess argument to 'fatal'.
15995 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
15996 This avoids several warnings with gcc -Wstrict-overflow.
15997 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
15998 directly, rather than having caller test rule sign. This avoids
15999 some unnecessary tests.
16000 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
16001 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
16002 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
16004 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16005 (xfont_open): Avoid unnecessary tests.
16007 * composite.c (composition_gstring_put_cache): Use unsigned integer.
16009 * composite.h, composite.c (composition_gstring_put_cache):
16010 Use EMACS_INT, not int, for length.
16012 * composite.h (COMPOSITION_DECODE_REFS): New macro,
16013 breaking out part of COMPOSITION_DECODE_RULE.
16014 (COMPOSITION_DECODE_RULE): Use it.
16015 * composite.c (get_composition_id): Remove unused local vars,
16016 by using the new macro.
16018 * textprop.c (set_text_properties_1): Change while to do-while,
16019 since the condition is always true at first.
16021 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16022 (interval_deletion_adjustment): Return unsigned value.
16025 * process.c (list_processes_1, create_pty, read_process_output):
16026 (exec_sentinel): Remove vars that were set but not used.
16027 (create_pty): Remove unnecessary "volatile"s.
16028 (Fnetwork_interface_info): Avoid possibility of int overflow.

16030 (read_process_output): Simplify nbytes computation if buffered.
16032 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
16034 * syntax.c (scan_words): Remove var that was set but not used.
16035 (update_syntax_table): Use unsigned instead of int.
16037 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
16038 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
16039 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
16041 * print.c (print_error_message): Avoid int overflow.
16043 * font.c (font_list_entities): Redo for clarity,
16044 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
16046 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
16047 (font_score): Avoid potential overflow in diff calculation.
16049 * fns.c (substring_both): Remove var that is set but not used.
16050 (sxhash): Redo loop for clarity and to avoid wraparound warning.
16052 * eval.c (funcall_lambda): Rename local to avoid shadowing.
16054 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
16055 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
16056 can always succeed if overflow has undefined behavior.
16058 * search.c (boyer_moore, wordify): Remove vars set but not used.
16059 (wordify): Omit three unnecessary tests.
16061 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
16062 All callers changed. This avoids the need for an unused var.
16064 * casefiddle.c (casify_region): Remove var that is set but not used.
16066 * dired.c (file_name_completion): Remove var that is set but not used.
16068 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
16070 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16071 (Finsert_file_contents): Remove unnecessary code checking fd.
16073 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
16074 Check for integer overflow on size calculations.
16076 * buffer.c (Fprevious_overlay_change): Remove var that is set
16079 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16080 Remove vars that are set but not used.
16081 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16082 (timer_check_2): Mark vars as initialized.
16084 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16086 * image.c (lookup_image): Remove var that is set but not used.
16087 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16089 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16090 that are set but not used.
16092 * xfns.c (make_invisible_cursor): Don't return garbage
16093 if XCreateBitmapFromData fails (Bug#8410).
16095 * xselect.c (x_get_local_selection, x_handle_property_notify):
16096 Remove vars that are set but not used.
16098 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

16102 Remove var that is set but not used.
16103 (scroll_bar_windows_size): Now size_t, not int.
16104 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16105 Check for overflow.
16107 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16108 (map_tty_color) [!defined MSDOS]: Likewise.
16110 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16112 * coding.c: Remove vars that are set but not used.
16113 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

16120 that is set but not used.
16122 * print.c (print_object): Remove var that is set but not used.
16124 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16125 The gnulib version avoids calling malloc in the usual case,
16126 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16127 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16128 * filelock.c (current_lock_owner): Likewise.
16129 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16130 * sysdep.c: Include allocator.h, careadlinkat.h.
16131 (emacs_no_realloc_allocator): New static constant.
16132 (emacs_readlink): New function.
16133 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16134 ../lib/careadlinkat.h.
16136 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
16138 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

16160 do not dereference NULL upon failed strdup
16161 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16162 (ns_get_family): Likewise.
16164 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16166 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16168 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16170 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16173 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16175 Add lexical binding.
16177 * window.c (Ftemp_output_buffer_show): New fun.
16178 (Fsave_window_excursion):
16179 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.

16184 Bind Qinternal_interpreter_environment.
16185 (Feval_buffer): Bind Qlexical_binding.
16186 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16188 (syms_of_lread): Declare `lexical-binding'.
16190 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16192 * keyboard.c (eval_dyn): New fun.
16193 (menu_item_eval_property): Use it.
16195 * image.c (parse_image_spec): Use Ffunctionp.
16197 * fns.c (concat, mapcar1): Accept byte-code-functions.
16199 * eval.c (Fsetq): Handle lexical vars.
16200 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16201 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16202 (FletX, Flet): Obey lexical binding.
16203 (Fcommandp): Handle closures.
16204 (Feval): New `lexical' arg.
16205 (eval_sub): New function extracted from Feval. Use it almost
16206 everywhere where Feval was used. Look up vars in lexical env.
16208 (Ffunctionp): Move from subr.el.
16209 (Ffuncall): Handle closures.
16210 (apply_lambda): Remove `eval_flags'.
16211 (funcall_lambda): Handle closures and new byte-code-functions.
16212 (Fspecial_variable_p): New function.
16213 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16214 but without exporting it to Lisp.
16216 * doc.c (Fdocumentation, store_function_docstring):
16217 * data.c (Finteractive_form): Handle closures.
16219 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16222 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16224 (exec_byte_code): New function extracted from Fbyte_code to handle new
16225 calling convention for byte-code-functions. Add new byte-codes.
16227 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
16229 * alloc.c (Fmake_symbol): Init new `declared_special' field.
16231 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16233 * xdisp.c (redisplay_internal): Fix prototype.
16235 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16237 * xdisp.c (SCROLL_LIMIT): New macro.
16238 (try_scrolling): Use it when setting scroll_limit.
16239 Limit scrolling to 100 screen lines.
16240 (redisplay_window): Even when falling back on "recentering",
16241 position point in the window according to scroll-conservatively,
16242 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16244 (try_scrolling): When point is above the window, allow searching
16245 as far as scroll_max, or one screenful, to compute vertical
16246 distance from PT to the scroll margin position. This prevents
16247 try_scrolling from unnecessarily failing when
16248 scroll-conservatively is set to a value slightly larger than the
16249 window height. Clean up the case of PT below the margin at bottom
16250 of window: scroll_max can no longer be INT_MAX. When aggressive
16251 scrolling is in use, don't let point enter the opposite scroll
16252 margin as result of the scroll.
16253 (syms_of_xdisp) <scroll-conservatively>: Document the
16254 threshold of 100 lines for never-recentering scrolling.
16256 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

16261 (message_log_check_duplicate): Remove parameters `prev_bol' and
16262 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16263 (redisplay_internal): Remove parameter `preserve_echo_area',
16264 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16266 * indent.c (Fvertical_motion):
16267 * window.c (window_scroll_pixel_based, Frecenter):
16268 Don't pass `need_y_p' to `move_it_by_lines'.
16270 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16272 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16273 steal a few bits to be more compact.
16274 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16275 Remove unneeded casts.
16277 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16279 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16281 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16282 binding" message (bug#7967).
16284 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16286 Fix more problems found by GCC 4.6.0's static checks.
16288 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16289 Remove unused local var.
16291 * editfns.c (Fmessage_box): Remove unused local var.
16293 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16294 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16295 Omit unused local vars.
16296 * window.c (shrink_windows): Omit unused local var.
16297 * menu.c (digest_single_submenu): Omit unused local var.
16298 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16299 Omit unused local var.
16301 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16302 Don't assume string length fits in int.
16303 (keyremap_step, read_key_sequence): Use size_t for sizes.

16306 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
16307 instead of alloca (Bug#8344).
16309 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16310 (Fbacktrace_frame): Don't assume nframes fits in int.
16312 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

16319 * cm.c (calccost): Turn while-do into do-while, for clarity.
16321 * keyboard.c (syms_of_keyboard): Use the same style as later
16322 in this function when indexing through an array. This also
16323 works around GCC bug 48267.
16325 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16327 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16329 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16330 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16332 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16333 This avoids undefined behavior on integer overflow, and is a bit
16334 more convenient anyway since it is compared to a size_t variable.
16336 Variadic C functions now count arguments with size_t, not int.
16337 This avoids an unnecessary limitation on 64-bit machines, which
16338 caused (substring ...) to crash on large vectors (Bug#8344).

16348 * fns.c (concat): Likewise.
16349 * frame.c (x_set_frame_parameters): Likewise.
16350 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16351 0 if not found, not -1. All callers changed.
16353 * alloc.c (garbage_collect): Don't assume stack size fits in int.
16354 (stack_copy_size): Now size_t, not int.
16355 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
16357 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
16359 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
16360 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

16376 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
16377 don't set the hook to nil, but remove the offending function instead.
16378 (Qcommand_hook_internal): Remove, unused.
16379 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
16380 Vcommand_hook_internal.
16382 * eval.c (enum run_hooks_condition): Remove.
16383 (funcall_nil, funcall_not): New functions.
16384 (run_hook_with_args): Call each function through a `funcall' argument.

16523 * w32term.c (x_set_glyph_string_clipping):
16524 Don't pass uninitialized region to CombineRgn.
16526 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
16528 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
16529 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
16530 (Fx_close_connection): Remove unused variable `i'.

16548 2011-03-23 Julien Danjou <julien@danjou.info>
16550 * term.c (Fsuspend_tty, Fresume_tty):
16551 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
16552 * window.c (temp_output_buffer_show):
16553 * insdel.c (signal_before_change):
16554 * frame.c (Fhandle_switch_frame):
16555 * fileio.c (Fdo_auto_save):
16556 * emacs.c (Fkill_emacs):
16557 * editfns.c (save_excursion_restore):
16558 * cmds.c (internal_self_insert):
16559 * callint.c (Fcall_interactively):
16560 * buffer.c (Fkill_all_local_variables):
16561 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
16563 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
16564 unconditionally since it does the check itself.
16566 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
16568 Fix more problems found by GCC 4.5.2's static checks.
16570 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16571 the first time through the loop, since we know p0 < p1 then.
16572 This also avoids a gcc -Wstrict-overflow warning.
16574 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16575 leading to a memory leak, possible in functions like
16576 load_charset_map_from_file that can allocate an unbounded number
16577 of objects (Bug#8318).
16579 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16580 that could (at least in theory) be that large.
16582 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16583 This is less likely to overflow, and avoids undefined behavior if
16584 overflow does occur. All callers changed. Use strtoul to scan
16585 for the unsigned long integer.
16586 (pint2hrstr): Simplify and tune code slightly.
16587 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
16589 * scroll.c (do_scrolling): Work around GCC bug 48228.
16590 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
16592 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
16593 This also avoids a warning with gcc -Wstrict-overflow.
16594 (validate_x_resource_name): Simplify count usage.
16595 This also avoids a warning with gcc -Wstrict-overflow.
16597 * fileio.c (Fcopy_file): Report error if fchown or fchmod
16600 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
16602 * process.c (Fmake_network_process): Use socklen_t, not int,
16603 where POSIX says socklen_t is required in portable programs.
16604 This fixes a porting bug on hosts like 64-bit HP-UX, where
16605 socklen_t is wider than int (Bug#8277).
16606 (Fmake_network_process, server_accept_connection):
16607 (wait_reading_process_output, read_process_output):
16610 * process.c: Rename or move locals to avoid shadowing.

16620 Make tparam.h and terminfo.c consistent.
16621 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
16622 Include tparam.h instead, since it declares them.
16623 * cm.h (PC): Remove extern decl; tparam.h now does this.
16624 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
16625 * terminfo.c: Include tparam.h, to check interfaces.
16626 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
16627 (tparam): Adjust signature to match interface in tparam.h;
16628 this removes some undefined behavior. Check that outstring and len
16629 are zero, which they always are with Emacs.
16630 * tparam.h (PC, BC, UP): New extern decls.
16632 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
16633 (xftfont_open): Rename locals to avoid shadowing.
16635 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
16636 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
16637 (OTF_TAG_SYM): Omit macro if not needed.

16645 * xml.c (make_dom): Now static.
16647 * composite.c (composition_compute_stop_pos): Rename local to
16649 (composition_reseat_it): Remove unused locals.
16650 (find_automatic_composition, composition_adjust_point): Likewise.
16651 (composition_update_it): Mark var as initialized.
16652 (find_automatic_composition): Mark vars as initialized,
16653 with a FIXME (Bug#8290).
16655 character.h: Rename locals to avoid shadowing.
16656 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
16657 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
16658 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
16659 (BUF_DEC_POS): Be more systematic about renaming local temporaries
16660 to avoid shadowing.
16662 * textprop.c (property_change_between_p): Remove; unused.
16664 * intervals.c (interval_start_pos): Now static.
16666 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

16669 Rename locals to avoid shadowing.
16671 * sound.c (wav_play, au_play, Fplay_sound_internal):
16672 Fix pointer signedness.
16673 (alsa_choose_format): Remove unused local var.
16674 (wav_play): Initialize a variable to 0, to prevent undefined
16675 behavior (Bug#8278).
16677 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
16679 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
16681 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
16682 clobbering (Bug#8298).
16683 * sysdep.c (sys_subshell): Likewise.
16684 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
16686 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
16687 This should get cleaned up, so that child_setup has the
16688 same signature on all platforms.
16690 * callproc.c (call_process_cleanup): Now static.
16691 (relocate_fd): Rename locals to avoid shadowing.
16693 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
16695 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
16696 not to be necessary, and produces flickering.
16698 2011-03-20 Glenn Morris <rgm@gnu.org>
16700 * config.in: Remove file.
16702 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
16704 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
16705 are now in src/globals.h.
16706 (syms_of_minibuf): Remove spurious & from previous change.
16708 2011-03-20 Leo Liu <sdl.web@gmail.com>
16710 * minibuf.c (completing-read-function): New variable.
16711 (completing-read-default): Rename from completing-read.
16712 (completing-read): Call completing-read-function.
16714 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16716 * xfaces.c (Fx_load_color_file):
16717 Read color file from absolute filename (bug#8250).
16719 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16721 * makefile.w32-in: Update dependencies.
16723 2011-03-17 Eli Zaretskii <eliz@gnu.org>
16725 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

16732 (sigchld_handler): Now static.
16734 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
16735 That way, the code declares only the vars that it needs.
16736 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
16737 * s/cygwin.h (PTY_ITERATION): Likewise.
16738 * s/darwin.h (PTY_ITERATION): Likewise.

16742 * process.c (allocate_pty): Don't declare stb unless it's needed.
16744 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
16745 (CONSTANTLIM): Remove; unused.
16746 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
16747 Define only if needed.
16749 * unexelf.c (unexec): Name an expression,
16750 to avoid gcc -Wbad-function-cast warning.
16751 Use a different way to cause a compilation error if anyone uses
16752 n rather than nn, a way that does not involve shadowing.
16753 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
16755 * deps.mk (unexalpha.o): Remove; unused.
16757 New file unexec.h, the (simple) interface for unexec (Bug#8267).
16758 * unexec.h: New file.
16759 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
16760 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
16761 Depend on unexec.h.
16762 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
16763 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
16764 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
16765 Change as necessary to match prototype in unexec.h.
16767 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
16769 (back_comment, skip_chars): Mark vars as initialized.
16771 * character.h (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS):

16777 * print.c (Fredirect_debugging_output): Fix pointer signedess.
16779 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
16780 warning when compiling print.c.

16783 instead of using an uninitialized var.
16784 (font_sort_entities): Mark var as initialized.
16786 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
16788 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

16800 * floatfns.c (domain_error2): Define only if needed.
16801 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
16803 * alloc.c (mark_backtrace): Move decl from here ...
16804 * lisp.h: ... to here, so that it can be checked.
16806 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
16807 (Fdefvar): Rewrite so as not to use empty "else".
16808 (lisp_indirect_variable): Name an expression,
16809 to avoid gcc -Wbad-function-cast warning.
16810 (Fdefvar): Rename locals to avoid shadowing.
16812 * callint.c (quotify_arg, quotify_args): Now static.
16813 (Fcall_interactively): Rename locals to avoid shadowing.
16814 Use const pointer when appropriate.
16816 * lisp.h (get_system_name, get_operating_system_release):
16817 Move decls here, to check interfaces.
16818 * process.c (get_operating_system_release): Move decl to lisp.h.

16820 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
16821 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
16822 some of which prompt warnings from gcc -Wbad-function-cast.
16823 (Fformat_time_string, Fencode_time, Finsert_char):
16824 (Ftranslate_region_internal, Fformat):
16825 Rename or remove local vars to avoid shadowing.
16826 (Ftranslate_region_internal): Mark var as initialized.
16828 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
16831 * lisp.h (eassert): Check that the argument compiles, even if
16832 ENABLE_CHECKING is not defined.
16834 * data.c (Findirect_variable): Name an expression, to avoid
16835 gcc -Wbad-function-cast warning.
16836 (default_value, arithcompare, arith_driver, arith_error): Now static.
16837 (store_symval_forwarding): Rename local to avoid shadowing.
16838 (Fmake_variable_buffer_local, Fmake_local_variable):

16843 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
16844 Rename locals to avoid shadowing.
16845 (mark_stack): Move local variables into the #ifdef region where
16847 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
16848 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
16850 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
16851 (GC_STRING_CHARS): Remove; not used.
16852 (Fmemory_limit): Cast sbrk's returned value to char *.
16854 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
16855 avoids undefined behavior in theory.
16857 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
16859 Use functions, not macros, for up- and down-casing (Bug#8254).
16860 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16861 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
16862 to use the following functions instead of these macros.
16863 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
16864 EMACS_INT, since callers assume the returned value fits in int.
16865 (upcase1): Likewise, for UPCASE_TABLE.
16866 (uppercasep, lowercasep, upcase): New static inline functions.
16867 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
16868 the race-condition problem in the old DOWNCASE.
16870 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
16871 Rename locals to avoid shadowing.
16872 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
16873 (regex_compile, re_search_2, re_match_2_internal):
16874 Remove unused local vars.
16875 (FREE_VAR): Rewrite so as not to use empty "else",
16876 which gcc can warn about.
16877 (regex_compile, re_match_2_internal): Mark locals as initialized.
16878 (RETALLOC_IF): Define only if needed.
16879 (WORDCHAR_P): Likewise. This one is never needed, but is used
16880 only in a comment talking about a compiler bug, so put inside
16881 the #if 0 of that comment.
16882 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
16883 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
16886 * search.c (boyer_moore): Rename locals to avoid shadowing.
16887 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
16888 (PREV_CHAR_BOUNDARY): Likewise.
16890 * search.c (simple_search): Remove unused var.
16892 * dired.c (compile_pattern): Move decl from here ...

16896 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
16898 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
16900 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
16901 Rename locals to avoid shadowing.
16902 (Fvertical_motion): Mark locals as initialized.
16904 * casefiddle.c (casify_object, casify_region): Now static.
16905 (casify_region): Mark local as initialized.
16907 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
16909 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
16910 New macros, so that the caller can use some names other than
16911 gcpro1, gcpro2, etc.
16912 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
16914 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
16915 argument, for consistency with GCPRO2_VAR, etc: it is now the
16916 prefix of the variable, not the variable itself. All uses
16918 * dired.c (directory_files_internal, file_name_completion):
16919 Rename locals to avoid shadowing.
16921 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
16922 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
16923 dired.c's scmp function, had undefined behavior.
16924 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16925 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
16926 * buffer.h: ... to here, because these macros use current_buffer,
16927 and the new implementation with inline functions needs to have
16928 current_buffer in scope now, rather than later when the macros
16930 (downcase, upcase1): New static inline functions.
16931 (DOWNCASE, UPCASE1): Reimplement using these functions.
16932 This avoids undefined behavior in expressions like
16933 DOWNCASE (x) == DOWNCASE (y), which previously suffered
16934 from race conditions in accessing the global variables
16935 case_temp1 and case_temp2.
16936 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
16937 * lisp.h (case_temp1, case_temp2): Remove their decls.
16938 * character.h (ASCII_CHAR_P): Move from here ...
16939 * lisp.h: ... to here, so that the inline functions mentioned
16940 above can use them.
16942 * dired.c (directory_files_internal_unwind): Now static.
16944 * fileio.c (file_name_as_directory, directory_file_name):
16945 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
16947 (file_name_as_directory): Use const pointers when appropriate.
16948 (Fexpand_file_name): Likewise. In particular, newdir might
16949 point at constant storage, so make it a const pointer.
16950 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
16951 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
16953 (Fset_file_times, Finsert_file_contents, auto_save_error):
16954 Rename locals to avoid shadowing.
16956 * minibuf.c (choose_minibuf_frame_1): Now static.
16957 (Ftry_completion, Fall_completions): Rename or remove locals
16958 to avoid shadowing.
16960 * marker.c (bytepos_to_charpos): Remove; unused.
16962 * lisp.h (verify_bytepos, count_markers): New decls,
16963 so that gcc does not warn that these functions aren't declared.
16965 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
16966 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
16967 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
16968 (copy_text): Remove unused local var.
16970 * filelock.c (within_one_second): Now static.
16971 (lock_file_1): Rename local to avoid shadowing.
16973 * buffer.c (fix_overlays_before): Mark locals as initialized.
