3 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4 (print_load_command_name): Add case LC_DATA_IN_CODE.
5 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
7 2012-09-21 Glenn Morris <rgm@gnu.org>
9 * eval.c (Frun_hook_with_args_until_success)
10 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
12 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
14 * fileio.c (Ffile_selinux_context): Only call freecon when
15 lgetfilecon succeeded.
16 (Fset_file_selinux_context): Likewise. (Bug#12444)
18 2012-09-21 Eli Zaretskii <eliz@gnu.org>
20 * xdisp.c (try_window_reusing_current_matrix): Under bidi
21 reordering, locate the cursor by calling set_cursor_from_row; if
22 that fails, clear the desired glyph matrix before returning a
23 failure indication to the caller. Fixes leaving garbled display
24 when fast scrolling with a down-key. (Bug#12403)
25 (compute_stop_pos_backwards): Fix a typo that caused crashes while
26 scrolling through multibyte text.
28 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
30 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
31 calling mark_vectorlike since that's the one that marks the window.
32 (mark_discard_killed_buffers): Mark the final cdr.
33 * window.h (struct window): Move prev/next_buffers to the
35 * window.c (make_window): Initialize prev/next_buffers manually.
37 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
39 Omit unused arg EXPECTED from socket hooks.
40 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
41 * nsterm.m (ns_term_init):
42 * termhooks.h (struct terminal.read_socket_hook):
43 * w32inevt.c (w32_console_read_socket):
44 * w32term.c (w32_read_socket):
45 * xterm.c (XTread_socket):
46 Omit unused arg EXPECTED. All callers changed.
47 (store_user_signal_events): Return void, not int, since callers no
48 longer care about the return value. All uses changed.
50 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
52 * w32gui.h (XParseGeometry): Do not declare.
54 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
56 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
57 Ignore 'expected'. See Eli Zaretskii in
58 <http://bugs.gnu.org/12471#8> (last line).
60 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
61 (XParseGeometry): Now static. Substitute extremal values for
62 values that are out of range.
64 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
66 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
68 * nsfns.m (XParseGeometry): Remove.
69 (Fx_create_frame): Call x_set_offset to correctly interpret
72 * frame.c (read_integer, XParseGeometry): Moved from w32xfns.c.
73 (Fx_parse_geometry): If there is a space in string, call
74 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
76 2012-09-17 Eli Zaretskii <eliz@gnu.org>
78 * search.c (scan_buffer): Use character positions in calls to
79 region_cache_forward and region_cache_backward, not byte
80 positions. (Bug#12196)
82 * w32term.c (w32_read_socket): Set pending_signals to 1, like
83 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
85 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
86 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
87 emacs_blocked_malloc, now deleted.
89 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
91 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
92 The workaround was for improving performance on Solaris 2.4, but
93 is getting in the way now. Emacs will still work if someone is
94 still running Solaris 2.4 in a museum somewhere; Sun dropped
95 support for Solaris 2.4 in 2003.
96 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
97 * process.c (create_process) [HAVE_WORKING_VFORK]:
98 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
99 since Emacs no longer uses vfork on that platform.
101 2012-09-17 Glenn Morris <rgm@gnu.org>
103 * emacs.c: Use COPYRIGHT.
105 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
107 Remove configure's --without-sync-input option (Bug#12450).
108 When auditing signal-handling in preparation for cleaning it up,
109 I found that SYNC_INPUT has race conditions and would be a real
110 pain to fix. Since it's an undocumented and deprecated
111 configure-time option, now seems like a good time to remove it.
112 Also see <http://bugs.gnu.org/11080#16>.
113 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
114 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
115 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
117 (check_depth) [XMALLOC_OVERRUN_CHECK]:
118 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
119 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
120 (dont_register_blocks, bytes_used_when_reconsidered)
121 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
122 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
123 [!SYSTEM_MALLOC && !SYNC_INPUT]:
124 Remove. All uses removed.
125 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
126 implementation, one that depends on whether the new macro
127 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
129 * atimer.c (run_timers, handle_alarm_signal):
130 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
131 (handle_async_input, process_pending_signals)
132 (handle_input_available_signal, init_keyboard):
133 * nsterm.m (ns_read_socket):
134 * process.c (wait_reading_process_output):
135 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
136 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
138 * xterm.c (XTread_socket):
140 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
141 * eval.c (handling_signal): Remove. All uses removed.
142 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
143 All uses replaced with the SYNC_INPUT version.
144 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
146 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
149 * font.c (Ffont_shape_gstring): Remove unused local.
151 2012-09-16 Glenn Morris <rgm@gnu.org>
153 * Makefile.in (clean): No longer run nextstep's clean.
155 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
157 (ns-app): Move here from ns.mk, and simplify.
158 (clean): Simplify nextstep entry.
159 * ns.mk: Remove file.
161 2012-09-16 Kenichi Handa <handa@gnu.org>
163 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
164 not covert the last few charactes.
166 2012-09-16 Kenichi Handa <handa@gnu.org>
168 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
169 here, but just check the validity of glyphs in the glyph-string.
171 2012-09-16 Martin Rudalics <rudalics@gmx.at>
173 * window.c (Fwindow_parameter, Fset_window_parameter): Accept
174 any window as argument (Bug#12452).
176 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
178 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
179 to ns_term_init to avoid memory leak.
181 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
182 explicit retain/release.
183 (ns_term_init): Only allow one display. Initialize outerpool and
186 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
188 Port _setjmp fix to POSIXish hosts as well as Microsoft.
189 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
190 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
191 the Microsoft problem in a different way, by altering ../nt/config.nt.
193 2012-09-15 Eli Zaretskii <eliz@gnu.org>
208 * w16select.c: Remove inclusion of setjmp.h, as it is now included
209 by lisp.h. This completes removal of setjmp.h inclusion
210 erroneously announced in the previous commit. (Bug#12446)
212 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
215 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
216 not defined as a macro. The latter happens on MS-Windows.
219 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
221 Port better to POSIX hosts lacking _setjmp (Bug#12446).
222 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
223 Some instances of '#include <setjmp.h>' removed, if the
224 only reason for the instance was because "lisp.h" was included.
225 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
226 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
227 and _longjmp with the new symbols. Emacs already uses _setjmp if
228 available, so this change affects only POSIXish hosts that have
229 sigsetjmp but not _setjmp, such as some versions of Solaris and
230 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
231 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
232 (png_load_body) [HAVE_PNG]:
233 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
234 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
235 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
236 since PNG requires jmp_buf. This is the only exception to the
237 general rule that we now use sys_setjmp and sys_longjmp.
238 This exception is OK since this code does not change the signal
239 mask or longjmp out of a signal handler.
241 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
243 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
244 Include "syssignal.h", for 'main_thread'.
246 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
248 Avoid out-of-range marker position (Bug#12426).
249 * insdel.c (replace_range, replace_range_2): Adjust
250 markers before overlays, as suggested by comments.
251 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
252 Remove redundant check before calling offset_intervals.
254 2012-09-14 Martin Rudalics <rudalics@gmx.at>
256 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
257 current buffer (Bug#12387).
259 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
261 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
263 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
265 Use a more backwards-compatible timer format (Bug#12430).
266 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
267 vector element, not from the 4th, since PSECS is now at the end.
268 (Fcurrent_idle_time): Doc fix.
270 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
272 Function to mark objects and remove killed buffers at once.
273 * alloc.c (discard_killed_buffers): Rename to ...
274 (mark_discard_killed buffers) ... new name. Add marking
275 of remaining objects. Fix comment. Adjust users.
276 (mark_object): Do not touch frame buffer lists here.
277 * frame.c (delete_frame): Reset frame buffer lists here.
279 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
281 Better workaround for GNOME bug when --enable-gcc-warnings.
282 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
283 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
284 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
286 Simplify SIGIO usage (Bug#12408).
287 The code that dealt with SIGIO was crufty and confusing, e.g., it
288 played tricks like "#undef SIGIO" but these tricks were not used
289 consistently. Simplify mostly by not #undeffing standard symbols,
290 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
291 or not as we please) rather than "defined SIGIO" (standard symbol
292 that we probably shouldn't #undef).
293 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
294 Modules that need it can include it.
295 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
296 * dispextern.h (ignore_sigio): New decl.
297 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
298 unconditionally, since it's now a no-op if !USABLE_SIGIO.
299 * emacs.c (shut_down_emacs):
300 * keyboard.c (kbd_buffer_store_event_hold):
301 Use ignore_sigio rather than invoking 'signal' directly.
302 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
304 (FIONREAD, SIGIO): Do not #undef.
305 (tty_read_avail_input): Use #error rather than a syntax error.
306 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
307 for I_PIPE, used by SETUP_SLAVE_PTY.
308 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
309 * sysdep.c (croak): Remove; no longer needed. This bit of
310 temporary code, with Fred N. Fish's comment that it's temporary,
311 has been in Emacs since at least 1992!
312 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
313 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
314 * syssignal.h (croak): Remove decl.
315 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
316 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
317 now that we're termios-only.
318 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
319 * term.c (dissociate_if_controlling_tty): Use #error rather than
322 Work around GCC and GNOME bugs when --enable-gcc-warnings.
323 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
324 to work around GNOME bug 683906.
325 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
326 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
327 This works around GCC bug 54561.
329 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
331 More fixes for 'volatile' and setjmp/longjmp.
332 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
333 * image.c (struct png_load_context) [HAVE_PNG]: New type.
334 (png_load_body) [HAVE_PNG]:
335 (jpeg_load_body) [HAVE_JPEG]:
336 New function, with most of the old parent function's body.
337 (png_load) [HAVE_PNG]:
338 (jpeg_load) [HAVE_JPEG]:
339 Invoke the new function, to avoid longjmp munging our locals.
340 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
341 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
342 longjmp is passed 2, as the C standard doesn't guarantee this.
343 Instead, store the failure code into mgr->failure_code.
345 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
347 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
348 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
349 (syms_of_keyboard): Remove support for unread-command-char.
351 2012-09-12 Eli Zaretskii <eliz@gnu.org>
353 * w32proc.c (sys_kill): If PID is our process ID and the signal is
354 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
355 violation. (Bug#12426)
357 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
359 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
361 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
363 * eval.c: Add `inhibit-debugger'.
364 (Qinhibit_debugger): New symbol.
365 (call_debugger): Bind it instead of Qdebug_on_error.
366 (maybe_call_debugger): Test Vinhibit_debugger.
367 (syms_of_eval): Define inhibit-debugger.
368 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
369 (syms_of_xdisp): Remove inhibit-debug-on-message.
371 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
373 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
374 If a nonvolatile local variable is written before a _longjmp to
375 the frame containing the variable, and is read after the _longjmp,
376 the value read is indeterminate. Some local variables of type
377 'struct handler' and 'struct catchtag' are used in this way, so
378 mark each of their slots as volatile if the slot can be set before
379 _longjmp and read afterwards.
380 * lisp.h (struct handler): var and chosen_clause are now volatile.
381 (struct catchtag): val, next, and pdlcount are now volatile.
383 * bidi.c (bidi_push_it, bidi_pop_it):
384 * fns.c (copy_hash_table):
385 * image.c (define_image_type):
386 * keyboard.c (kbd_buffer_store_event_hold):
387 * process.c (Fprocess_send_eof):
388 * xfaces.c (x_create_gc) [HAVE_NS]:
389 * xgselect.c (xg_select):
390 Prefer assignment to memcpy when either will do.
392 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
393 Use pointer-to-a-pointer to simplify and avoid a NILP check each
394 time an item is removed. No need to mark this function 'inline';
395 the compiler knows better than we do.
397 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
399 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
400 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
401 to change_frame_size (Bug#12388).
402 (windowDidResize:): Pass YES to updateFrameSize.
404 * nsterm.h: Add delay parameter to updateFrameSize.
406 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
408 Discard killed buffers from deleted window and frame objects.
409 This reduces an amount of references to killed buffers and
410 helps GC to reclaim them faster.
411 * alloc.c (discard_killed_buffers): New function.
412 (mark_object): Use it for deleted windows and frames.
413 (mark_object): If symbol's value is set up for a killed buffer
414 or deleted frame, restore it's global binding.
415 * data.c (swap_in_global_binding): Add GC notice.
416 (swap_in_symval_forwarding): Use convenient set_blv_where.
417 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
418 * window.h: ... to here.
420 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
422 Convenient macro to check whether the buffer is live.
423 * buffer.h (BUFFER_LIVE_P): New macro.
424 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
425 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
427 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
429 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
430 composition cases (Bug#12364).
432 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
433 overhang of succeeding glyphs overlapping box cursor.
435 * w32term.c (x_draw_glyph_string): Likewise.
437 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
439 Simplify, document, and port floating-point (Bug#12381).
440 The porting part of this patch fixes bugs on non-IEEE platforms
441 with frexp, ldexp, logb.
442 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
444 * floatfns.c: Simplify discussion of functions that Emacs doesn't
445 support, by removing commented-out code and briefly listing the
446 C89 functions excluded. The commented-out stuff was confusing
447 maintenance, e.g., we thought we needed cbrt but it was commented out.
448 (logb): Remove decl; no longer needed.
449 (isfinite): New macro, if not already supplied.
450 (isnan): Don't replace any existing macro.
451 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
452 are present on all C89 platforms.
453 (Ffrexp): Do not special-case zero, as frexp does the right thing
455 (Flogb): Do not use logb, as it doesn't have the desired meaning
456 on hosts that use non-base-2 floating point. Instead, stick with
457 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
458 frexp, to avoid getting an unspecified result.
460 * xdisp.c (Qinhibit_debug_on_message): Now static.
462 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
464 * nsterm.m (ns_update_begin): Set clip path to whole view by using
465 NSBezierPath (Bug#12131).
467 2012-09-10 Chong Yidong <cyd@gnu.org>
469 * fns.c (Fdelq, Fdelete): Doc fix.
471 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
473 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
474 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
476 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
478 * lisp.h (make_lisp_ptr): New macro to replace XSET.
479 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
482 2012-09-09 Eli Zaretskii <eliz@gnu.org>
484 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
485 left fringe if the window has a left margin. This avoids leaving
486 traces of the cursor because its leftmost pixel is not drawn over.
488 * dispnew.c (update_window_line): When the left margin area of a
489 screen line is updated, set the redraw_fringe_bitmaps_p flag of
490 that screen line. (Bug#12277)
492 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
494 Assume C89 or later for math functions (Bug#12381).
495 This simplifies the code, and makes it a bit smaller and faster,
496 and (most important) makes it easier to clean up signal handling
497 since we can stop worring about floating-point exceptions in
498 library code. That was a problem before C89, but the problem
499 went away many years ago on all practical Emacs targets.
500 * data.c, image.c, lread.c, print.c:
501 Don't include <math.h>; no longer needed.
502 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
503 might be autoconfigured, as that never happens.
505 * doprnt.c (DBL_MAX_10_EXP):
507 Remove. C89 or later always defines these.
508 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
509 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
510 (arith_error, domain_error, domain_error2):
511 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
512 no longer needed -- we simply return what C returns. All uses removed.
513 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
515 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
516 Remove. All uses expanded, as these macros are no longer used
517 more than once and are now more trouble than they're worth.
518 (Ftan): Use tan, not sin / cos.
519 (Flogb): Assume C89 frexp.
520 (fmod_float): Assume C89 fmod.
521 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
522 (init_floatfns): Remove. All uses removed.
524 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
526 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
527 compositeToPoint for OSX < 10.6 (Bug#12390).
529 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
531 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
532 This produces more-accurate results.
534 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
536 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
539 2012-09-08 Chong Yidong <cyd@gnu.org>
541 * syntax.c (Fstring_to_syntax): Doc fix.
543 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
545 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
546 in the internal border.
547 (x_set_window_size): Remove static variables and their usage.
548 (ns_redraw_scroll_bars): Fix NSTRACE arg.
549 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
550 fringe/internal border adjustment (Bug#11052).
551 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
552 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
553 (ns_fix_rect_ibw): Remove.
554 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
555 (ns_dumpglyphs_box_or_relief): Ditto.
556 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
558 (ns_dumpglyphs_image): Ditto.
559 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
561 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
562 their usage. Add fringe_extended_p and its use as in other terms.
563 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
564 scroll bar was removed.
565 (updateFrameSize): New function.
566 (windowDidResize): Move code to updateFrameSize and call it.
568 * nsterm.h (EmacsView): Add updateFrameSize.
570 2012-09-07 Chong Yidong <cyd@gnu.org>
572 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
574 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
576 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
578 More signal-handler cleanup (Bug#12327).
579 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
580 Problem introduced when merging patches. Noted by Eli Zaretskii in
581 <http://bugs.gnu.org/12327#67>.
582 * floatfns.c: Comment fix.
583 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
584 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
585 and anyway the declaration is harmless even if SIGDANGER is not defined.
586 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
587 defined BROKEN_FIONREAD). systty.h formerly did this, but other
588 source files not surprisingly expected syssignal.h to define, or
589 not define, SIGIO, and it's cleaner to do it that way, for consistency.
590 Include <sys/ioctl.h>, for FIONREAD.
591 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
592 This eliminates a problem whereby other files mysteriously had
593 to include "syssignal.h" before including "systty.h" if they
594 wanted to use "#ifdef SIGIO".
596 2012-09-07 Eli Zaretskii <eliz@gnu.org>
598 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
600 * w32.c (sigemptyset): Empty the set.
601 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
603 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
605 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
607 * alloc.c (mark_buffer): Revert unsafe marking optimization.
608 (mark_object): Likewise for frame objects.
610 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
612 * syssignal.h (handle_on_main_thread): Always declare,
613 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
614 This ports to platforms without HAVE_PTHREAD.
616 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
618 Signal-handler cleanup (Bug#12327).
619 Emacs's signal handlers were written in the old 4.2BSD style with
620 sigblock and sigmask and so forth, and this led to some
621 inefficiencies and confusion. Rewrite these to use
622 pthread_sigmask etc. without copying signal sets around. Also,
623 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
624 'signal', and instead use functions that do not attempt to take
625 over the system name space. This patch causes Emacs's text
626 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
627 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
628 Do not include <signal.h> or "syssignal.h", as these
629 modules do not use signals.
630 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
631 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
632 Do not include <signal.h>, as "syssignal.h" does that for us now.
633 * atimer.c (sigmask_atimers): New function.
634 (block_atimers, unblock_atimers): New functions,
635 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
637 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
638 no longer needed here.
639 * emacs.c (main): Inspect existing signal handler with sigaction,
640 so that there's no need to block and unblock SIGHUP.
641 * sysdep.c (struct save_signal): New member 'action', replacing
642 old member 'handler'.
643 (save_signal_handlers, restore_signal_handlers):
644 Use sigaction instead of 'signal' to save and restore.
645 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
646 New function. All users of 'signal' modified to use set_sighandler
647 if they're writeonly, and to use sys_signal if they're read+write.
648 (emacs_sigaction_init, forwarded_signal): New functions.
649 (sys_signal): Remove. All uses replaced by calls to sigaction
650 and emacs_sigaction_init, or by direct calls to 'signal'.
651 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
652 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
653 all uses replaced by pthread_sigmask etc. calls.
654 * syssignal.h: Include <signal.h>.
655 (emacs_sigaction_init, forwarded_signal): New decls.
656 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
657 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
658 (sigmask, sys_sigmask): Remove; no longer needed.
659 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
660 (sigblock, sigunblock, sigfree):
661 (sigsetmask) [!defined sigsetmask]:
662 Remove. All uses replaced by pthread_sigmask.
663 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
664 no longer need to be replaced, and its typical old uses
665 are now done via emacs_sigaction_init and sigaction.
666 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
667 (sys_sigdel): Remove; unused.
668 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
670 2012-09-06 Eli Zaretskii <eliz@gnu.org>
672 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
673 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
675 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
677 Explicitly mark buffer_defaults and buffer_local_symbols.
678 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
679 mark_local_symbols here.
680 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
681 since special buffers aren't marked here any more.
682 (allocate_buffer): Chain new buffer with all_buffers here...
683 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
685 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
686 (syms_of_buffer): Remove staticpro of the above.
687 (init_buffer_once): Set names for buffer_defaults and
688 buffer_local_symbols.
690 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
692 Use bool for booleans in font-related modules.
693 * font.c (font_intern_prop, font_style_to_value)
694 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
695 (generate_otf_features, font_check_otf_features, font_check_otf)
696 (font_match_p, font_list_entities, font_at):
697 * fontset.c (fontset_id_valid_p, reorder_font_vector
698 (fontset_find_font, Fset_fontset_font)
699 (face_suitable_for_char_p) [0]:
700 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
701 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
702 (m17n_flt_initialized, ftfont_shape_by_flt):
703 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
704 * nsfont.m (nsfont_draw):
705 * w32font.c (w32font_draw):
706 * w32term.c (x_draw_glyphless_glyph_string_foreground):
707 Use bool for booleans.
708 * font.h: Adjust to above API changes.
709 (struct font, struct font_driver, struct font_driver_list):
710 Use bool for booleans.
711 (struct font): Remove useless member encoding_type.
713 * fontset.c, xftfont.c: Omit unnecessary static decls.
715 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
717 * alloc.c (mark_object): Revert window marking code
718 since it's unsafe for the Fset_window_configuration.
720 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
722 Fix race conditions with signal handlers and errno (Bug#12327).
723 Be more systematic about preserving errno whenever a signal
724 handler returns, even if it's not in the main thread. Do this by
725 renaming signal handlers to distinguish between signal delivery
726 and signal handling. All uses changed.
727 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
728 * data.c (deliver_arith_signal): Rename from arith_error.
729 * dispnew.c (deliver_window_change_signal): Rename from
730 window_change_signal.
731 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
732 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
733 * keyboard.c (deliver_input_available_signal): Rename from
734 input_available_signal.
735 (deliver_user_signal): Rename from handle_user_signal.
736 (deliver_interrupt_signal): Rename from interrupt_signal.
737 * process.c (deliver_pipe_signal): Rename from send_process_trap.
738 (deliver_child_signal): Rename from sigchld_handler.
739 * atimer.c (handle_alarm_signal):
740 * data.c (handle_arith_signal):
741 * dispnew.c (handle_window_change_signal):
742 * emacs.c (handle_fatal_signal, handle_danger_signal):
743 * keyboard.c (handle_input_available_signal):
744 * keyboard.c (handle_user_signal, handle_interrupt_signal):
745 * process.c (handle_pipe_signal, handle_child_signal):
746 New functions, with the actual signal-handling code taken from the
747 original respective signal handlers, sans the sporadic attempts to
748 preserve errno, since that's now done by handle_on_main_thread.
749 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
750 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
751 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
753 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
754 Move initialization of main_thread to sysdep.c's init_signals.
755 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
756 our usage, and simplifies the mainline code.
757 (record_child_status_change): New static function, as a helper
758 for handle_child_signal, and with most of the old child handler's
760 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
761 (handle_child_signal): Use the above.
762 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
763 Moved here from emacs.c.
764 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
765 code moved here from emacs.c's main function.
766 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
767 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
768 lets callers save and restore errno properly.
770 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
772 Remove redundant or unused things here and there.
773 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
774 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
775 * editfns.c (Fcompare_buffer_substrings): Likewise.
776 * frame.h (struct terminal, struct font_driver_list):
777 Remove redundant declarations.
778 * window.h (Qleft, Qright): Likewise.
780 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
782 Do not mark objects from deleted buffers, windows and frames.
783 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
784 (mark_object): Likewise for windows and frames.
786 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
788 * alloc.c (valid_lisp_object_p): Treat killed buffers,
789 buffer_defaults and buffer_local_symbols as valid objects.
790 Return special value to denote them.
792 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
794 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
795 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
796 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
797 (file_name_absolute_p, Fsubstitute_in_file_name):
798 (check_executable, check_writable, Ffile_accessible_directory_p)
799 (Fset_file_selinux_context, Fdefault_file_modes)
800 (Finsert_file_contents, choose_write_coding_system)
801 (Fwrite_region, build_annotations, a_write, e_write)
803 * filelock.c (boot_time_initialized, get_boot_time)
804 (get_boot_time_1, lock_file_1, within_one_second):
805 * floatfns.c (in_float):
806 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
807 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
808 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
809 * lisp.h (struct Lisp_Hash_Table.cmpfn):
810 * window.c (compare_window_configurations):
811 Use bool for booleans.
812 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
813 (Fdefault_file_modes): Now mode_t, not int, for modes.
814 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
815 (internal_delete_file): Now returns void, not a (boolean) int,
816 since nobody was looking at the return value.
817 * lisp.h, window.h: Adjust to above API changes.
819 * xdisp.c (set_message): Simplify and reindent last change.
821 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
823 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
825 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
827 * eval.c (call_debugger): Make the function non-static so that we
828 can call it from set_message.
830 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
831 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
833 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
835 Give more-useful info on a fatal error (Bug#12328).
836 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
837 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
838 of doing the work ourselves.
839 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
841 (fatal_error_backtrace): New function, taken from the guts
842 of the old fatal_error_signal, but with a new option to output
844 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
845 info about the signal than just its number.
846 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
847 * sysdep.c: Include <execinfo.h>
848 (emacs_backtrace): New function, taken partly from the previous
849 code of the 'die' function.
850 (emacs_abort): Call fatal_error_backtrace rather than abort.
852 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
854 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
855 eager (load-time) macro-expansion.
856 * lisp.mk (lisp): Add macroexp.
858 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
860 Simplify redefinition of 'abort' (Bug#12316).
861 Do not try to redefine the 'abort' function. Instead, redo
862 the code so that it calls 'emacs_abort' rather than 'abort'.
863 This removes the need for the NO_ABORT configure-time macro
864 and makes it easier to change the abort code to do a backtrace.
865 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
866 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
867 Remove; sysdep.c's emacs_abort now takes its place.
868 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
869 'abort' changed to use 'emacs_abort'.
870 * msdos.c (dos_abort) [defined abort]: Remove; not used.
871 (abort) [!defined abort]: Rename to ...
872 (emacs_abort): ... new name.
873 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
874 the place of the old 'abort' in emacs.c.
875 * w32.c, w32fns.c (abort): Do not #undef.
876 * w32.c (emacs_abort): Rename from w32_abort.
878 2012-09-04 Eli Zaretskii <eliz@gnu.org>
880 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
881 offsets[j].dv, since the y axis of the screen coordinates points
882 down, while the y axis of the font definition coordinates points
883 up. This fixes display of Arabic diacritics such as KASRA and
884 KASRATAN. (Bug#11860)
886 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
888 Be more systematic about _setjmp vs setjmp.
889 * alloc.c (test_setjmp, mark_stack):
890 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
891 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
892 (png_load, my_error_exit, jpeg_load):
893 * process.c (send_process_trap, send_process):
894 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
895 The underscored versions are up to 30x faster on some hosts.
896 Formerly, the code used setjmp+longjmp sometimes and
897 _setjmp+_longjmp at other times, with no particular reason to
898 prefer setjmp+longjmp.
900 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
902 Fix minor problem found by static checking.
903 * buffer.c (Fdelete_all_overlays): Return nil.
905 2012-09-03 Martin Rudalics <rudalics@gmx.at>
907 * buffer.c (Fdelete_all_overlays): New function.
909 2012-09-03 Chong Yidong <cyd@gnu.org>
911 * gtkutil.c: Add extern decl for Qxft.
913 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
915 * emacs.c, eval.c: Use bool for boolean.
916 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
917 (malloc_using_checking) [DOUG_LEA_MALLOC]:
918 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
919 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
920 (main, decode_env_path, Fdaemon_initialized):
921 * eval.c (call_debugger, Finteractive_p, interactive_p):
922 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
923 (maybe_call_debugger, Fbacktrace):
924 * process.c (read_process_output, exec_sentinel):
925 Use bool for booleans.
926 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
928 * eval.c (interactive_p): Omit always-true boolean argument
929 EXCLUDE_SUBRS_P. All callers changed.
930 * dispextern.h, lisp.h: Reflect above API changes.
931 * firstfile.c (dummy): Use the address of 'main', whose signature

1032 offset adjustment values separately for each cluster. (Bug#11860)
1034 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1035 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1036 about implicit conversions from integer to pointer.
1038 2012-09-01 Daniel Colascione <dancol@dancol.org>
1040 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

1094 window system declarations.
1096 * frame.h: Move common functions here: set_frame_menubar,
1097 x_set_window_size, x_sync, x_get_focus_frame,
1098 x_set_mouse_position, x_set_mouse_pixel_position,
1099 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

1185 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
1186 Add window_closed and button_values. Add void as return value for

1383 (Ffind_charset_region, char_charset, Fiso_charset):
1384 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
1385 (sub_char_table_set, sub_char_table_set_range)
1386 (char_table_set_range, optimize_sub_char_table)
1387 (map_sub_char_table):
1388 Use bool for boolean.
1389 * character.c (str_to_unibyte): Omit last boolean argument; it was
1390 always 0. All callers changed.
1391 * character.h, charset.h: Adjust to match previous changes.
1392 * character.h (char_printable_p): Remove decl of nonexistent function.
1393 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
1394 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
1395 are all boolean, so make them single-bit bitfields.
1397 * lisp.h (ASET): Remove attempt to detect side effects.
1398 It was meant to be temporary and it often doesn't work,
1399 because when IDX has side effects the behavior of IDX==IDX
1400 is undefined. See Stefan Monnier in
1401 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
1403 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
1405 * lisp.h (functionp): New function (extracted from Ffunctionp).
1406 (FUNCTIONP): Use it.
1407 * eval.c (Ffunctionp): Use it.
1409 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1411 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
1412 as that's faster and simpler than static storage. Don't bother
1413 with the g_main_context_query overhead if g_main_context_pending
1414 says no events are pending.
1415 (gfds, gfds_size): Remove these static vars.
1416 (xgselect_initialize): Remove; no longer needed.
1417 All uses and decls removed.
1419 * emacs.c (fatal_error_signal_hook): Remove.
1420 All uses removed. This leftover from old code was always 0.
1422 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
1423 * casefiddle.c (casify_object, casify_region):
1424 * casetab.c (set_case_table):
1425 * category.c, category.h (word_boundary_p):
1426 * category.h (CHAR_HAS_CATEGORY):
1427 Use bool for booleans, instead of int.
1429 2012-08-25 Eli Zaretskii <eliz@gnu.org>
1431 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
1433 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1435 On assertion failure, print backtrace if available.
1436 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1437 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1438 * Makefile.in (LIB_EXECINFO): New macro.
1441 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1442 * bytecode.c (exec_byte_code):
1443 * callint.c (check_mark, Fcall_interactively):
1444 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1445 (getenv_internal, sync_process_alive, call_process_exited):
1446 * lisp.h (USE_SAFE_ALLOCA):
1447 Use bool for booleans, instead of int.
1448 * lisp.h, process.h: Adjust prototypes to match above changes.
1449 * callint.c (Fcall_interactively): Don't assume the mark's
1450 offset fits in 'int'.
1452 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1454 * buffer.c, buffer.h: Use bool for boolean.
1455 * buffer.c (reset_buffer_local_variables)
1456 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1457 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

1459 (overlay_touches_p, overlay_strings, Foverlay_put)
1460 (report_overlay_modification, call_overlay_mod_hooks):
1461 (mmap_enlarge, mmap_set_vars):
1462 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1463 Use bool for booleans, instead of int.
1464 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1465 since the 1-or-0 return value is always ignored anyway.
1466 (mmap_initialized_p):
1467 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1468 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1470 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1472 * bidi.c: Use bool for boolean.
1473 This is a bit more readable, and makes the text segment of bidi.o
1474 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1475 Presumably it's faster too.
1476 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1478 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1479 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1480 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1481 (bidi_explicit_dir_char, bidi_level_of_next_char)
1482 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1483 Use bool for booleans, instead of int.
1484 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1485 (bidi_unshelve_cache): Adjust decls to match code.
1487 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1489 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1492 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1494 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1495 * atimer.h: Include <stdbool.h>.
1497 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1499 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1500 compile time tests instead of run time tests on systems that do
1502 (FRAME_MAC_P): Remove leftover from deleted code.
1503 * frame.c (syms_of_frame): Remove leftover from deleted code.
1505 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
1507 * nsterm.m (insertText:): Don't clear modifiers if code is space.
1509 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1511 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1512 Otherwise, the compiler complains about (A?B:C) where B is void
1513 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1514 (fontset_add): Return void, for FONTSET_ADD.
1516 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1518 * alloc.c: Use bool for booleans.
1519 (gc_in_progress, abort_on_gc)
1520 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1521 (dont_register_blocks) [GC_MALLOC_CHECK]:
1522 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1523 (check_string_bytes, make_specified_string, memory_full)
1524 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1525 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1526 (mark_stack, valid_pointer_p, make_pure_string)
1527 (Fgarbage_collect, survives_gc_p, gc_sweep):
1528 Use bool for booleans, instead of int.
1529 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1530 Remove unused local.
1531 * alloc.c (PURE_POINTER_P):
1532 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1533 * editfns.c (Fformat):
1534 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1536 * fns.c (sweep_weak_table):
1537 * lisp.h (suppress_checking, push_message, survives_gc_p)
1538 (make_pure_string, gc_in_progress, abort_on_gc):
1539 * lread.c (readchar, read1):
1540 * print.c (Fprin1_to_string):
1541 * xdisp.c (push_message):
1542 Use bool for booleans affected directly or indirectly by
1545 Make recently-introduced setters macros.
1546 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1547 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1548 (set_fontset_default, set_fontset_fallback): Rename from their
1549 upper-case counterparts, and make them functions rather than macros.
1550 This is more consistent with the other recently-introduced setters.
1551 These don't need to be inline, since they're local.
1553 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1555 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1556 the loop (Bug#12247).
1558 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1560 * lisp.h (vcopy): Use memcpy rather than our own loop.
1561 This fixes a performance regression introduced by the recent
1562 addition of vcopy. This means 'vcopy' will need to be modified
1563 for a copying collector, but that's OK. Also, tighten the
1564 checking in the assertion.
1566 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1568 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1569 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1570 non-base glyph for the width of the base character, according to
1571 what x_draw_composite_glyph_string_foreground expects.
1572 Generate WADJUST value according to composition_gstring_width's
1573 expectations, to produce correct width of the composed character.
1574 Reverse the sign of the DU offset produced by ScriptPlace.
1576 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1578 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1580 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1582 Avoid direct writes to contents member of struct Lisp_Vector.
1583 * lisp.h (vcopy): New function to copy data into vector.
1584 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
1585 * fns.c (Ffillarray): Use ASET.
1586 * keyboard.c (timer_check_2): Use AREF and ASET.
1587 (append_tool_bar_item, Frecent_keys): Use vcopy.
1588 * lread.c (read_vector): Use ASET.
1589 * msdos.c (Frecent_doskeys): Use vcopy.
1590 * xface.c (Finternal_copy_lisp_face): Use vcopy.
1591 (Finternal_merge_in_global_face): Use ASET and vcopy.
1592 * xfont.c (xfont_list_pattern): Likewise.
1594 2012-08-21 Martin Rudalics <rudalics@gmx.at>
1596 * window.c (Fwindow_point): For the selected window always return
1597 the position of its buffer's point.
1598 (Fset_window_point): For the selected window always go in its
1599 buffer to the specified position.
1601 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1603 Setter macros for fontsets.
1604 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1605 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1606 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1609 2012-08-20 Glenn Morris <rgm@gnu.org>
1611 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1612 Don't assume that `ln -f' works.
1614 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1616 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1617 and later about non-assignments with no effect. See discussion at
1618 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1621 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1623 Inline setter functions for Lisp_Objects slots of struct specbinding.
1624 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
1627 2012-08-20 Martin Rudalics <rudalics@gmx.at>
1629 * window.c (select_window): Always make selected window's buffer
1632 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1634 Use AREF and ASET for docstrings of category tables.
1635 * category.h (CATEGORY_DOCSTRING): Use AREF.
1636 (SET_CATEGORY_DOCSTRING): Use ASET.
1637 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
1639 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1641 Inline setter functions for hash table members.
1642 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
1643 (set_hash_hash, set_hash_index): Rename with _slot suffix.
1644 (set_hash_key_and_value, set_hash_index, set_hash_next)
1645 (set_hash_hash): New functions.
1646 * charset.c, fns.c: Adjust users.
1648 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1650 Inline getter and setter functions for per-buffer values.
1651 * buffer.h (per_buffer_default, set_per_buffer_default)
1652 (per_buffer_value, set_per_buffer_value): New functions.
1653 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
1654 * buffer.c, data.c: Adjust users.
1656 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
1658 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
1660 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
1662 Rely on <config.h> + <unistd.h> to declare 'environ',
1663 as gnulib does this if the system doesn't.
1664 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
1665 Remove declaration. MS-Windows declares it on stdlib.h which is
1666 included by conf_post.h.
1667 * emacs.c (environ) [DOUG_LEA_MALLOC]:
1668 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
1669 * vm-limit.c: Include <unistd.h>, for 'environ'.
1671 * unexaix.c, unexcoff.c: Include "mem-limits.h".
1672 (start_of_data): Remove decl; mem-limits.h provides it.
1674 * xdisp.c (handle_invisible_prop): Make it a bit faster
1675 and avoid a gcc -Wmaybe-uninitialized diagnostic.
1677 2012-08-19 Chong Yidong <cyd@gnu.org>
1679 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
1682 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
1684 * .gdbinit: Use call instead of set when calling a function in the
1687 * data.c (set_internal): Don't use set_blv_found.
1688 (Fkill_local_variable): Likewise.
1690 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
1692 * nsfont.m (ns_ascii_average_width): Ensure the string
1693 ascii_printable is initialized with a null-terminated character
1694 array. Otherwise, it can contain undesired extra characters.
1696 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1698 port new setting code to Sun C 5.8 2005/10/13
1699 * chartab.c, lisp.h (char_table_set, char_table_set_range):
1700 Return void, not Lisp_Object. Otherwise, the compiler
1701 complains about (A?B:C) where B is void and C is Lisp_Object
1702 when compiling CHAR_TABLE_SET, due to the recent change to
1703 the API of sub_char_table_set_contents.
1705 2012-08-18 Chong Yidong <cyd@gnu.org>
1707 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
1708 for the string case (Bug#3874).
1710 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1712 * buffer.h (BSET): Remove (Bug#12215).

1787 (TERMHOOKS_INLINE): New macro.
1788 (tset_charset_list, tset_selection_alist): New setter functions.
1789 * terminal.c (TERMHOOKS_INLINE):
1790 Define to EXTERN_INLINE, so that the corresponding functions
1791 are compiled into code.
1792 (tset_param_alist): New setter function.
1794 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>

2540 value of EMACSLOADPATH, as it is no longer needed.
2541 (check_windows_init_file): Now external, not static.

2592 * alloc.c (record_xmalloc): New function.
2593 * lisp.h (record_xmalloc): New decl.
2594 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
2595 more like a function. This is because the pointer cast is not
2596 needed. All uses changed.
2597 * print.c (print_string, print_error_message): Avoid length recalc.
2599 Improve fix for macroexp crash with debugging (Bug#12118).
2600 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to

2634 with addition of handling of symlinks and support for 'lstat'.
2635 If possible, get file's attributes and security information by
2636 handle, not by name. Produce S_IFLNK bit for symlinks, when
2637 called from 'lstat'.
2638 (stat, lstat): New functions, call 'stat_worker'.
2639 (symlink, readlink, careadlinkat): Rewritten to create and resolve
2640 symlinks when the underlying filesystem supports them.

2645 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
2646 checking subscripts; problem introduced with the recent
2647 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
2648 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
2649 since it's used in non-static inline functions now.
2651 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

3149 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
3150 Zaretskii in <http://bugs.gnu.org/12036#13>.
3151 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
3152 needed now that we have gdb_make_enums_visible.
3153 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
3154 (enum enum_USE_LSB_TAG):
3155 New enum types, packaging up enums that need to be exported to GDB.

3176 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3178 Fast save_excursion_save and save_excursion_restore.
3179 * lisp.h (struct Lisp_Excursion): New data type.
3180 (PVEC_EXCURSION): New pseudovector type.
3181 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
3182 to deal with it. Adjust comments.

3197 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
3198 emacs.c, as this is a more-suitable home. Had this been done earlier
3199 the fix for 12036 would have avoided some of the problems noted in
3200 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
3201 would have been more obvious.
3202 * emacs.c: Do not include <verify.h>; no longer needed.
3203 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
3204 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
3205 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

3211 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3212 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3213 not be usable in #if. This simplifies things.
3215 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
3217 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
3219 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

3222 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3223 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3224 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3225 Adjust to changes in lisp.h and emacs.c, by using
3226 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
3227 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
3228 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
3229 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
3230 instead of gdb_valbits.
3231 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
3232 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
3233 instead of gdb_array_mark_flag.
3234 (xboolvector): Get size from $->size, not $->header.size.
3235 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
3236 (xreload, hook-run, hookpost-run): Remove.
3237 * emacs.c: Include <verify.h>.
3238 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
3239 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
3241 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
3242 (gdb_USE_LSB_TAG): New enum constants.
3243 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3244 Also define these as enum constants, so they're visible to GDB.
3245 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
3246 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
3247 as constants, so they're visible to GDB.

3250 Now enum constants, not macros, so they're visible to GDB.
3251 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
3252 more convenient now. All uses changed.
3253 (VALMASK) [USE_LSB_TAG]: Also define in this case.

3263 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
3264 add argument, tune behavior, and adjust all callers.
3266 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
3268 Use typedef for EMACS_INT, EMACS_UINT.
3269 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
3270 than macros. This simplifies debugging in the usual case, since
3271 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
3272 and it allows expressions involving EMACS_INT casts.
3273 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
3275 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

3285 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
3287 Adjust buffer text indirection counters at the end of Fkill_buffer.
3288 * buffer.c (Fkill_buffer): Adjust indirection counters when the
3289 buffer is definitely dead. This should really fix an issue reported
3290 by Christoph Scholtes again. (Bug#12007).
3291 (init_buffer_once): Initialize indirection counters of
3292 buffer_defaults and buffer_local_symbols (for sanity and safety).
3294 2012-07-24 Eli Zaretskii <eliz@gnu.org>
3296 * xdisp.c (init_iterator): Don't compute dimensions of truncation
3297 and continuation glyphs on tooltip frames, leave them at zero.
3298 Avoids continued lines in tooltips. (Bug#11832)
3300 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

3325 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3327 Swap buffer text indirection counters in Fbuffer_swap_text.
3328 * buffer.c (Fbuffer_swap_text): Swap indirections too.
3329 This avoids crash reported by Christoph Scholtes at
3330 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
3332 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
3334 * nsmenu.m (Popdown_data): New struct.

3339 and autorelease them. Also autorelease img and matrix (Bug#12005).
3340 (dealloc): Remove (Bug#12005).

3357 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
3359 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
3360 as it's limited by the amount of memory, not by INT_MAX.
3362 2012-07-21 Eli Zaretskii <eliz@gnu.org>
3364 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
3365 in special-event-map. See the discussion at

3446 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
3447 'for_each_per_buffer_object_at'.
3448 All uses changed. It's better to use upper-case for macros that

3500 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
3502 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
3503 when invoking (make-bool-vector N t) and N is a positive

3511 padding before the data member of a bool vector.
3512 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
3513 than doing the check by hand with an abort ().
3515 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3517 * eval.c (Fdefvar): Don't check constants since we only set the var if
3518 it's not yet defined anyway (bug#11904).
3520 * lisp.h (last_undo_boundary): Declare new var.
3521 * keyboard.c (command_loop_1): Set it.
3522 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
3523 were auto-added by the command loop (bug#11774).
3525 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
3527 * w32font.c (Qsymbol): Remove local definition.

4036 function attribute, so we only use it if it exists in the
4039 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
4041 Avoid call to strlen in fast_c_string_match_ignore_case.
4042 * search.c (fast_c_string_match_ignore_case): Change to use
4043 length argument. Adjust users accordingly.
4044 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
4046 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

4085 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
4087 Remove "#define unix" that is no longer needed (Bug#11905).
4088 * s/aix4-2.h (unix): Remove; no longer needed.
4090 EMACS_TIME simplification (Bug#11875).
4091 This replaces macros (which typically do not work in GDB)
4092 with functions, typedefs and enums, making the code easier to debug.
4093 The functional style also makes code easier to read and maintain.
4094 * systime.h: Include <sys/time.h> on all hosts, not just if
4095 WINDOWSNT, since 'struct timeval' is needed in general.
4096 (EMACS_TIME): Now a typedef, not a macro.
4097 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
4099 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

4102 (EMACS_TIME_LE): Now functions, not macros.
4103 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
4104 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
4105 which are not functions. All uses rewritten to use:
4106 (make_emacs_time): New function.
4107 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
4108 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4109 not functions. All uses rewritten to use the following, respectively:
4110 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
4111 (add_emacs_time, sub_emacs_time): New functions.
4112 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
4113 * fileio.c (Fcopy_file):
4114 * xterm.c (XTflash): Get the current time closer to when it's used.
4115 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

4122 * frame.c (Fmake_terminal_frame):
4123 * gtkutil.c (get_utf8_string):
4125 * nsmenu.m (ns_update_menubar):
4126 * regex.c (regerror):
4127 Prefer memcpy to strncpy and strncat when either will do.
4128 * fileio.c (Fsubstitute_in_file_name):
4129 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
4130 (menu_separator_name_p):
4131 * nsmenu.m (ns_update_menubar):
4132 Prefer memcmp to strncmp when either will do.
4133 * nsterm.m: Include <ftoastr.h>.
4135 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
4136 Prefer snprintf to strncpy.
4137 * nsterm.m (ns_term_init):
4138 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4139 * nsterm.m (ns_term_init):
4140 Avoid the need for strncpy, by using build_string or
4141 make_unibyte_string directly. Use dtoastr, not snprintf.
4142 * process.c (Fmake_network_process): Diagnose service names that
4143 are too long, rather than silently truncating them or creating
4144 non-null-terminated names.
4145 (Fnetwork_interface_info): Likewise, for interface names.
4146 * sysdep.c (system_process_attributes) [GNU_LINUX]:
4147 Prefer sprintf to strncat.
4148 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
4149 Prefer vsnprintf to vsprintf + strncpy.
4151 2012-07-10 Glenn Morris <rgm@gnu.org>
4153 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
4154 Clarify fallback case.
4156 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4158 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
4159 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
4160 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
4161 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
4162 where argument type is known to be a Lisp_Cons.
4164 2012-07-10 Tom Tromey <tromey@redhat.com>
4166 * bytecode.c (BYTE_CODE_THREADED): New macro.
4167 (BYTE_CODES): New macro. Replaces all old byte-code defines.
4168 (enum byte_code_op): New type.

4172 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4174 Optimize pure C strings initialization.
4175 * lisp.h (make_pure_string): Fix prototype.
4176 (build_pure_c_string): New function, defined as static inline. This
4177 provides a better opportunity to optimize away calls to strlen when
4178 the function is called with compile-time constant argument.
4179 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
4180 argument, adjust users accordingly. Use build_pure_c_string where
4182 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
4183 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
4184 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
4186 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4188 Avoid calls to strlen in miscellaneous functions.
4189 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
4190 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
4191 * lread.c (openp): Likewise.
4193 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4195 Avoid calls to strlen in path processing functions.
4196 * fileio.c (file_name_as_directory): Add comment. Change to add
4197 srclen argument and return the length of result. Adjust users
4199 (directory_file_name): Fix comment. Change to add srclen argument,

4201 Adjust users accordingly.
4202 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
4204 2012-07-10 Glenn Morris <rgm@gnu.org>
4206 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
4207 Move PENDING_OUTPUT_COUNT definition to configure.
4209 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
4210 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
4211 * s/gnu.h (DATA_START): Move definitions to configure.
4213 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
4214 We include usg5-4-common.h, which defines them both.
4216 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
4217 O_RDONLY already includes it).
4219 Stop ns builds setting the EMACSLOADPATH environment variable.
4220 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4221 Now it does not set EMACSLOADPATH, just returns the load-path string.
4222 * nsterm.h: Update accordingly.
4223 * lread.c [HAVE_NS]: Include nsterm.h.
4224 (init_lread) [HAVE_NS]: Use ns_load_path.
4225 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
4227 2012-07-09 Glenn Morris <rgm@gnu.org>
4229 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
4230 since the included bsd-common.h does so.
4232 Stop ns builds setting the EMACSPATH environment variable.
4233 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
4234 (ns_init_paths): Do not set EMACSPATH.
4235 * nsterm.h (ns_exec_path): Add it.
4236 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
4239 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
4241 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
4243 * process.c (wait_reading_process_output): 'waitchannels' was unset
4244 when read_kbd || !NILP (wait_for_cell); fix this.
4246 Add GCC-style 'const' attribute to functions that can use it.
4247 * character.h (char_resolve_modifier_mask):
4248 * keyboard.h (make_ctrl_char):
4249 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
4250 (init_character_once, next_almost_prime, init_fns, init_image)
4251 (flush_pending_output, init_sound):
4252 * mem-limits.h (start_of_data):

4256 Declare the dummy function with ATTRIBUTE_CONST.
4257 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
4258 Add decls with ATTRIBUTE_CONST.
4260 Minor improvements to make_formatted_string.
4261 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
4262 where int is good enough, as vsprintf returns an int.
4263 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
4265 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4267 Use make_formatted_string to avoid double length calculation.
4268 * lisp.h (make_formatted_string): New prototype.
4269 * alloc.c (make_formatted_string): New function.
4270 * buffer.c (Fgenerate_new_buffer_name): Use it.

4274 * frame.c (make_terminal_frame, set_term_frame_name)
4275 (x_report_frame_params): Likewise.
4276 * image.c (gs_load): Likewise.
4277 * minibuf.c (get_minibuffer): Likewise.

4292 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4294 Move marker debugging code under MARKER_DEBUG.
4295 * marker.c (MARKER_DEBUG): Move marker debugging code under
4296 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4297 for bootstrap with --enable-checking (~3x slowdown reported
4298 by Juanma Barranquero <lekktu@gmail.com>).
4299 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4301 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4303 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
4304 See <http://bugs.gnu.org/11825#29>.
4306 2012-07-08 Eli Zaretskii <eliz@gnu.org>
4308 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4309 has no font, use the frame's font. (Bug#11813)
4310 (display_line): Add commentary about displaying truncation glyphs
4312 (produce_special_glyphs): Move here from term.c.
4314 * term.c (produce_special_glyphs): Move to xdisp.c.
4316 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4319 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4321 * xdisp.c (display_line): Avoid warning about implicit declaration
4324 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4326 * lisp.h: Remove empty conditional.
4328 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4330 * lread.c (load_path_check): Now static.
4332 Fix some minor --with-ns problems found by static checking.
4333 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
4334 (x_set_font) [!HAVE_X_WINDOWS]:
4335 * image.c (xpm_load_image) [HAVE_NS]:
4336 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4337 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4338 Remove unused local.
4339 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
4340 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
4341 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
4342 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
4343 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
4344 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
4345 Fix pointer signedness problem.
4346 * xfaces.c (FRAME_X_FONT_TABLE):
4347 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
4349 2012-07-07 Glenn Morris <rgm@gnu.org>
4351 * lread.c (load_path_check): New function, split from init_lread.
4352 (init_lread): Reorganize. Motivation:
4353 If EMACSLOADPATH is set, check/warn about that rather than the
4354 defaults, which we are not going to use. Hence we can remove
4355 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4356 Don't warn if site-lisp directories are missing.
4357 If not installed, start from a blank load-path, since
4358 PATH_LOADSEARCH refers to the eventual installation directories.
4360 2012-07-07 Eli Zaretskii <eliz@gnu.org>
4362 Support truncation and continuation glyphs on GUI frames, when
4363 fringes are disabled. (Bug#11832)
4364 * xdisp.c (init_iterator): Get dimensions of truncation and
4365 continuation glyphs even if on GUI frames.
4366 Adjust it->last_visible_x on GUI frames when the left or right fringes,
4367 or both, are absent.
4368 (start_display, move_it_in_display_line_to): Handle the case of a
4369 GUI frame without a fringe to display continuation or truncation
4371 (insert_left_trunc_glyphs): Support GUI frames: make sure
4372 truncation glyphs overwrite enough glyphs from the current line to
4373 have sufficient space in pixels.
4374 (display_line): Support truncation and continuation glyphs on GUI
4375 frames. If some spare pixels are left on the line after inserting
4376 the truncation glyphs, fill that space with a stretch glyph of a
4377 suitably computed width.
4379 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4380 produce_glyphs, to support GUI sessions.
4382 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4384 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4386 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4388 Do not require float-time's arg to fit in time_t (Bug#11825).
4389 This works better on hosts where time_t is unsigned, and where
4390 float-time is applied to the (negative) difference between two times.
4391 * editfns.c (decode_time_components): Last arg is now double *,
4392 not int *, and means to store all the result as a double, without
4393 worrying about whether the seconds part fits in time_t.
4394 All callers changed.
4395 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4396 All callers changed.
4397 (Ffloat_time): Do not fail merely because the specified time falls
4398 outside of time_t range.
4400 2012-07-07 Glenn Morris <rgm@gnu.org>
4402 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

4406 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
4408 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
4409 Update dependencies.
4411 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
4413 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4415 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
4416 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
4417 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
4418 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
4419 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
4420 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
4422 * xfont.c (compare_font_names): Redo to omit the need for casts.
4424 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4426 * xfns.c (Fx_change_window_property): Doc fix.
4427 * w32fns.c (Fx_change_window_property): Doc fix.
4429 * w32fns.c (Fx_window_property): Accept the same arguments as the
4430 X Windows version. Doc fix.
4431 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4433 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4434 Eli Zaretskii <eliz@gnu.org>
4436 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4437 Windows-specific code from nt/config.nt moved here.
4438 Obsolete settings removed.
4440 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4442 * process.c: Avoid unnecessary calls to gettime.
4443 (wait_reading_process_output): Don't get the time of day
4444 when gobbling data immediately and not waiting, as there's no need
4445 for it in that case. This removes a FIXME.
4447 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4449 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4450 is defined (Bug#11768).
4452 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4454 Fix marker debugging code.
4455 * marker.c (byte_char_debug_check): Do not perform the check
4456 if buffer is not multibyte.
4457 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4458 Call byte_char_debug_check with correct arguments.
4460 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4462 Compile marker debugging code only if ENABLE_CHECKING is defined.
4463 * marker.c (byte_char_debug_check, count_markers):
4464 Use only if ENABLE_CHECKING is defined.
4465 (byte_debug_flag): Remove.
4466 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4467 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4469 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4471 Avoid code repetition in marker-related functions.
4472 * marker.c (attach_marker): New function.
4473 (Fset_marker, set_marker_restricted, set_marker_both)
4474 (set_marker_restricted_both): Use it.
4475 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4476 Consistently rename charno to charpos.
4477 (marker_position): Add eassert.
4478 (marker_byte_position): Convert to eassert.

4484 * marker.c (unchain_marker): Simplify. Fix comments.
4486 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4488 Introduce fast path for the widely used marker operation.
4489 * alloc.c (build_marker): New function.
4490 * lisp.h (build_marker): New prototype.
4491 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
4492 * composite.c (autocmp_chars): Likewise.
4493 * editfns.c (buildmark): Remove.
4494 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
4495 (save_restriction_save): Use build_marker.
4496 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
4497 * window.c (save_window_save): Likewise.
4499 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4501 Do not use Fdelete_overlay in delete_all_overlays
4502 to avoid redundant calls to unchain_overlay.
4503 * buffer.c (drop_overlay): New function.
4504 (delete_all_overlays, Fdelete_overlay): Use it.
4505 * minibuf.c (get_minibuffer): Fix comment.
4507 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4509 Port to OpenBSD 5.1 amd64.
4510 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4511 This is needed for OpenBSD, and should be harmless on all BSD systems.
4512 Also, include <sys/sysctl.h>, as it should be available on all
4513 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4514 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4515 use p_pid member, not kp_proc.pid.
4517 2012-07-06 Glenn Morris <rgm@gnu.org>
4519 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4521 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4523 More xmalloc and related cleanup.
4524 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
4525 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

4529 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
4530 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
4531 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
4532 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4534 Omit needless casts involving void * pointers and allocation.
4535 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4536 as the former is more robust if P's type is changed.
4537 Prefer xzalloc to xmalloc + memset 0.
4538 Simplify malloc-or-realloc to realloc.
4539 Don't worry about xmalloc returning a null pointer.
4540 Prefer xstrdup to xmalloc + strcpy.
4541 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4543 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4544 alloca of a constant.
4546 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4548 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4549 hscroll is larger than the line width. Fixes long and futile
4550 looping inside extend_face_to_end_of_line (on a TTY) producing
4551 glyphs that are not needed and thrown away.
4553 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4555 * marker.c (set_marker_restricted_both): Simplify by using
4558 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4560 * editfns.c (region_limit): Simplify by using clip_to_bounds.
4562 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
4564 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
4565 not defined (Bug#11768).
4566 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
4567 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
4568 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
4569 followed by gtk_box_set_homogeneous (Bug#11768).
4570 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4571 (update_theme_scrollbar_width, xg_create_scroll_bar):
4572 Use gtk_scrollbar_new (Bug#11768).
4573 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
4574 (is_box_type): New function (Bug#11768).
4575 (xg_tool_item_stale_p): Call is_box_type.
4576 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
4577 with default display (Bug#11768).
4579 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4581 * xdisp.c (window_hscroll_limited): New function.
4582 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
4583 coordinates when window's hscroll is set to insanely large
4586 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
4588 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
4589 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
4591 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4594 * lisp.h (xzalloc): New prototype. Omit needless casts.
4595 * alloc.c (xzalloc): New function. Omit needless casts.
4596 * charset.c: Omit needless casts. Convert all calls to
4597 xmalloc with following memset to xzalloc.

4647 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4649 * fileio.c (time_error_value): Check the right error number.
4650 Problem reported by Troels Nielsen in
4651 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
4653 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4655 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
4656 This should be fixed in a better way; see Eli Zaretskii in
4657 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
4658 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
4660 * fileio.c (time_error_value): Rename from special_mtime.
4661 The old name's problems were noted by Eli Zaretskii in
4662 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
4664 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
4665 This variable's comment says Emacs needs at least one GDB-visible
4666 symbol of type enum pvec_type, to work around GDB problems.
4667 The symbol's value doesn't matter.
4669 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
4670 that causes compilation to fail on pre-C99 compilers.
4672 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
4674 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
4675 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
4677 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4679 * buffer.c (init_buffer_once): Fix initialization of
4680 headers for buffer_defaults and buffer_local_symbols.
4681 Reported by Juanma Barranquero <lekktu@gmail.com>.
4683 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
4685 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
4686 * lisp.h (enum pvec_type): Use fewer bits.
4687 (PSEUDOVECTOR_SIZE_BITS): New constant.
4688 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
4689 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
4690 change in pvec_type.
4691 (PSEUDOVECTOR_TYPEP): New macro.
4692 (TYPED_PSEUDOVECTORP): Use it.
4693 * fns.c (internal_equal): Adapt code to extract pvectype.
4694 * emacs.c (gdb_pvec_type): Update type.
4695 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
4696 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
4697 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
4698 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
4699 (sweep_vectors): Use it. Use local var `total_bytes' instead of
4700 abusing vector->header.next.nbytes.
4701 (live_vector_p): Use PVEC_TYPE.
4702 (mark_object): Adapt code to extract pvectype. Use switch.
4704 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4706 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
4707 Tighten new eassert a bit.
4709 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4711 Fix compilation with --enable-gcc-warnings and -O1
4713 * doprnt.c (doprnt): Change type of tem to int, initialize
4714 to avoid compiler warning. Add eassert.
4715 * search.c (simple_search): Initialize match_byte to avoid
4716 compiler warning. Add eassert.
4718 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4720 Avoid weird behavior with large horizontal scrolls.
4721 Without this change, for example, large hscroll values would
4722 mess up Emacs's display on Fedora 15 x86, presumably due to
4723 overflows in int calculations in the display code.
4724 Also, if buffers had long lines, Emacs would freeze.
4725 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
4726 (set_window_hscroll): New function, containing the old guts of
4727 Fset_window_hscroll. Return the clipped value.
4728 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
4729 This avoids the need to check against PTRDIFF_MAX.
4731 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
4733 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4735 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
4737 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4739 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
4740 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
4741 since GCC 4.4.6 issues a bogus warning for them.
4743 Fix bugs in file timestamp newness comparisons.
4744 * fileio.c (Ffile_newer_than_file_p):
4745 * lread.c (Fload): Use full timestamp resolution of files,
4746 not just the 1-second resolution, so that files that are only
4747 slightly newer still count as newer.
4748 * fileio.c (Ffile_newer_than_file_p): Don't assume file
4749 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
4751 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
4753 * fileio.c: Improve handling of file time marker. (Bug#11852)
4754 (special_mtime): New function.
4755 (Finsert_file_contents, Fverify_visited_file_modtime):
4756 Use it to set special mtime values consistently.
4758 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
4760 * fileio.c (Finsert_file_contents): Properly handle st_mtime
4761 marker for non-existing file. (Bug#11852)
4763 2012-07-03 Glenn Morris <rgm@gnu.org>
4765 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
4766 and did not make it into globals.h).
4768 2012-07-03 Tom Tromey <tromey@redhat.com>
4770 * window.c (Fset_window_margins, Fset_window_fringes)
4771 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
4772 * textprop.c (Fprevious_property_change): No longer static.
4773 * syntax.c (Fsyntax_table_p): No longer static.
4774 * process.c (Fget_process, Fprocess_datagram_address): No longer

4788 * dired.c (Ffile_attributes): No longer static.
4789 * composite.c (Fcomposition_get_gstring): No longer static.
4790 * callproc.c (Fgetenv_internal): No longer static.
4792 * ccl.h: Remove EXFUNs.
4793 * buffer.h: Remove EXFUNs.
4794 * dispextern.h: Remove EXFUNs.
4795 * intervals.h: Remove EXFUNs.
4796 * fontset.h: Remove EXFUN.
4797 * font.h: Remove EXFUNs.
4798 * dosfns.c (system_process_attributes): Remove EXFUN.
4799 * keymap.h: Remove EXFUNs.
4800 * lisp.h: Remove EXFUNs.
4801 * w32term.h: Remove EXFUNs.
4802 * window.h: Remove EXFUNs.
4803 * xsettings.h: Remove EXFUN.
4804 * xterm.h: Remove EXFUN.
4806 2012-07-03 Glenn Morris <rgm@gnu.org>
4808 * lisp.h (Frandom): Make it visible to C.
4809 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
4810 buffer for invisible buffers. (Bug#1229)
4812 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4814 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
4815 values which aren't power of 2.
4816 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
4817 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
4820 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
4822 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
4824 * alloc.c (mark_object): Revert part of last patch to use `switch'.
4826 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4828 * alloc.c (allocate_vector_block): Remove redundant
4829 calls to mallopt if DOUG_LEA_MALLOC is defined.
4830 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
4831 avoid calls to mallopt if zero_vector is returned.
4833 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4835 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
4836 is enabled, avoid dereferencing NULL current_sblock if
4839 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4841 Cleanup basic buffer management.
4842 * buffer.h (struct buffer): Change layout to use generic vector
4843 marking code. Fix some comments. Change type of 'clip_changed'
4844 to bitfield. Remove unused #ifndef old.
4845 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
4846 (GET_OVERLAYS_AT): Fix indentation.
4847 (for_each_per_buffer_object_at): New macro.
4848 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
4849 (Fbuffer_local_variables): Use it.
4850 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
4851 * alloc.c (allocate_buffer): Adjust to match new layout of
4852 struct buffer. Fix comment.
4853 (mark_overlay): New function.
4854 (mark_buffer): Use it. Use mark_vectorlike to mark normal
4855 Lisp area of struct buffer.
4856 (mark_object): Use it. Adjust marking of misc objects
4857 and related comments.
4859 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
4861 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
4862 wrapper that is not needed because the wrapped code is a no-op (zero
4863 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
4864 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
4866 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
4868 * alloc.c (mark_buffer): Simplify. Remove prototype.
4869 (mark_object): Add comment. Reorganize marking of vector-like
4870 objects. Use CHECK_LIVE for all vector-like objects except buffers
4871 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
4872 Avoid redundant calls to mark_vectorlike for bool vectors.
4874 2012-06-30 Glenn Morris <rgm@gnu.org>
4876 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
4878 * epaths.in (PATH_SITELOADSEARCH): New.
4879 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
4880 This is rather than relying on --enable-locallisppath elements
4881 having "site-lisp" in their names. (Bug#10208#25, 11658)
4883 2012-06-30 Eli Zaretskii <eliz@gnu.org>
4885 * w32proc.c (sys_select): Accept and ignore one more argument.
4887 * w32.c (emacs_gnutls_pull): Call select with one more argument.
4889 * sysselect.h [DOS_NT]: Don't include sys/select.h.
4890 (pselect) [!MS_DOS]: Redirect to sys_select.
4892 * sysdep.c: Don't include dos.h and dosfns.h.
4894 * process.c (sys_select):
4895 * msdos.c (sys_select): Accept one more argument and ignore it.
4897 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
4898 adapt data types and code to that.
4901 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
4902 which clashes with the gnulib function of the same name.
4904 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
4906 * font.c (font_style_to_value, font_style_symbolic)
4907 (font_prop_validate_style): Add type checks for values in
4910 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
4912 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
4915 2012-06-29 Eli Zaretskii <eliz@gnu.org>
4917 * xdisp.c (try_window_id): Undo last change.
4919 * w32.c (getwd): Adjust commentary about startup_dir.
4920 (init_environment): Always call sys_access, even in non-MSVC
4921 builds. Don't chdir to the directory of the Emacs executable.
4922 This undoes code from 1997 which was justified by the need to
4923 "avoid conflicts when removing and renaming directories". But its
4924 downside was that every relative file name was being interpreted
4925 relative to the directory of the Emacs executable, which can never
4926 be TRT. In particular, it broke sys_access when called with
4927 relative file names.
4928 (sys_access): Map GetLastError to errno.
4930 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4932 * window.h (struct window): Change type of 'fringes_outside_margins'
4933 to bitfield. Fix comment. Adjust users accordingly.
4934 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
4936 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
4939 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
4941 * gnutls.c (emacs_gnutls_handshake):
4942 Add QUIT to make the loop interruptible.
4944 2012-06-29 Glenn Morris <rgm@gnu.org>
4946 * charset.c (init_charset): Make lack of etc/charsets fatal.
4948 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4950 * editfns.c (region_limit): Fix type mismatch.
4952 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4954 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
4955 undefined. Convert from xassert to eassert.
4956 * nsmenu.m: Convert from xassert to eassert.

5120 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
5122 Use sprintf return value instead of invoking strlen on result.
5123 In the old days this wasn't portable, since some sprintf
5124 implementations returned char *. But they died out years ago and
5125 Emacs already assumes sprintf returns int.
5126 Similarly for float_to_string.
5127 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

5135 Use sprintf or float_to_string result to avoid need to call strlen.
5136 * data.c (Fnumber_to_string):
5137 Use make_unibyte_string, since the string must be ASCII.
5138 * lisp.h, print.c (float_to_string): Now returns int length.
5139 * term.c (produce_glyphless_glyph):
5140 Use sprintf result rather than recomputing it.
5142 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
5143 * Makefile.in (ALL_CFLAGS):
5144 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

5171 * xfns.c (x_window): Remove redundant cast.
5173 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
5175 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
5176 `const char *' to `char *' to avoid compiler warning.
5178 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
5180 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
5181 instead of truncating it to 63 (admittedly a generous limit).
5183 * process.c: Fix spelling and caps in comments.

5240 * dispnew.c (Fsleep_for, sit_for):
5241 * keyboard.c (kbd_buffer_get_event):
5242 * process.c (Faccept_process_output):
5243 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
5244 This improves on the previous patch, which introduced a bug
5245 when time_t is unsigned and as wide as intmax_t.
5246 See <http://bugs.gnu.org/9000#51>.
5248 2012-06-23 Eli Zaretskii <eliz@gnu.org>
5250 * dispnew.c (sit_for, Fsleep_for):
5251 * keyboard.c (kbd_buffer_get_event):

5311 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5313 Support higher-resolution time stamps (Bug#9000).
5314 The time stamps are only nanosecond-resolution at the C level,
5315 since that's the best that any real-world system supports now.
5316 But they are picosecond-resolution at the Lisp level, as that's
5317 easy, and leaves room for future OS improvements.
5319 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5322 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5323 Don't get current time unless it's needed.
5325 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5326 now provides it if it's absent.
5327 (start_atimer): Port to higher-res time stamps.
5328 Check for time stamp overflow. Don't get current time more
5329 often than is needed.
5331 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5332 Include systime.h, not time.h.
5333 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
5335 * dired.c: Include stat-time.h.
5336 (Ffile-attributes): File times now have higher resolution.

5339 (struct image): Timestamp now has higher resolution.
5341 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5342 has at least microseconds now. All uses removed.
5343 (update_frame, update_single_window, update_window, update_frame_1)
5344 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5345 (duration_to_sec_usec): Remove; no longer needed.
5347 * editfns.c (time_overflow): Now extern.
5348 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
5349 (float-time, Fformat_time_string, Fcurrent_time_string)
5350 (Fcurrent_time_zone): Accept and generate higher-resolution

5353 (decode_time_components, lisp_seconds_argument): New functions.
5354 (make_time): Now static.
5355 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
5356 Report an error if the time is invalid, rather than having the caller
5359 * fileio.c: Include <stat-time.h>
5360 (Fcopy_file): Copy higher-resolution time stamps.
5361 Prefer to set the time stamp via a file descriptor if that works.
5362 (Fset_file_times, Finsert_file_contents, Fwrite_region)
5363 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
5364 (Fvisited_file_modtime, Fset_visited_file_modtime):
5365 Support higher-resolution time stamps.
5367 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
5369 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
5371 * image.c (prepare_image_for_display, clear_image_cache)
5372 (lookup_image): Port to higer-resolution time stamps.
5374 * keyboard.c (start_polling, bind_polling_period):
5375 Check for time stamp overflow.
5376 (read_char, kbd_buffer_get_event, timer_start_idle)
5377 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
5378 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5379 Port to higher-resolution time stamps. Do not assume time_t is signed.
5380 (decode_timer): New function. Timers are now vectors of length 9,
5381 not 8, to accommodate the picosecond component.
5382 (timer_check_2): Use it.
5384 * nsterm.m (select_timeout, timeval_subtract): Remove.
5385 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5386 as they're a bit more accurate and handle overflow better.
5387 (ns_select): Change prototype to be compatible with pselect.
5388 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5389 * nsterm.h (ns_select): Adjust prototype.
5391 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5392 us-resolution time stamps.
5393 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5395 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5397 * lisp.h (time_overflow): New decl.
5398 (wait_reading_process_output): First arg is now intmax_t, not int,
5399 to accommodate larger waits.
5401 * process.h (struct Lisp_Process.read_output_delay):
5402 Now counts nanoseconds, not microseconds.
5403 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
5405 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
5406 (wait_reading_process_output):
5407 Port to ns-resolution time stamps.
5408 (Faccept_process_output, wait_reading_process_output):
5409 Check for time stamp overflow. Do not assume time_t is signed.
5410 (select_wrapper): Remove; we now use pselect.
5411 (Fprocess_attributes): Now generates ns-resolution time stamps.
5413 * sysdep.c: Include utimens.h. Don't include utime.h
5414 or worry about struct utimbuf; gnulib does that for us now.
5415 (gettimeofday): Remove; gnulib provides a substitute.
5416 (make_timeval): New function.
5417 (set_file_times): Now sets ns-resolution time stamps.
5418 New arg FD; all uses changed.
5419 (time_from_jiffies, ltime_from_jiffies, get_up_time)
5420 (system_process_attributes):
5421 Now returns ns-resolution time stamp. All uses changed.
5422 Check for time stamp overflow.
5424 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5425 provides a substitute now.
5427 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5428 since it guarantees struct timespec.
5429 (EMACS_TIME): Now struct timespec, so that we can support
5430 ns-resolution time stamps.
5431 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5432 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5433 (EMACS_USECS): Remove.
5434 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5435 so multiply the arg by 1000 before storing it.
5436 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
5438 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
5439 Port to ns-resolution time stamps.
5440 (EMACS_TIME_NEG_P): Remove; replaced by....
5441 (EMACS_TIME_SIGN): New macro.
5442 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)

5445 (make_timeval, make_lisp_time, decode_time_components): New decls.
5446 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in

5488 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5489 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,

5541 gets killed during executing of this function (Bug#11665).

5544 run by this hook should not change the current buffer.
5546 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

5912 would mishandle a string argument "Xc" if X was a multibyte
5913 character of length 2: it would truncate after X's first byte
5914 rather than including all of X.
5916 2012-06-06 Chong Yidong <cyd@gnu.org>
5918 * buffer.c (word_wrap): Doc fix.
5920 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>
5922 * xdisp.c (note_mode_line_or_margin_highlight): Pacify gcc -Wall.

5931 (temacs$(EXEEXT)): Disable memory randomization for the temacs
5932 binary via PaX flags if the paxctl utility is available.
5933 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5934 Restore PaX flags to their default. (Bug#11398)

5938 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
5941 2012-06-03 Chong Yidong <cyd@gnu.org>
5943 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
5944 (note_mode_line_or_margin_highlight): If there is no help echo,
5945 use mode-line-default-help-echo. Handle the case where the mouse
5946 position is past the end of the mode line string.
5948 * buffer.c (buffer_local_value_1): New function, split from
5949 Fbuffer_local_value; can return Qunbound.
5950 (Fbuffer_local_value): Use it.
5951 (Vmode_line_format): Docstring tweaks.
5953 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5955 * sysdep.c (system_process_attributes): Improve comment.
5957 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
5959 * keyboard.c: Export real-this-command to Elisp.
5960 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
5961 and DEFVAR it. Update all users.
5963 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5965 * minibuf.c (Fassoc_string): Remove duplicate declaration.
5967 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
5968 Convert pctcpu and pctmem to Lisp float properly.
5969 Let the compiler fold better, as 100.0/0x8000 is exact.
5971 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
5973 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
5976 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
5978 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
5980 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
5982 For a 'struct window', replace some Lisp_Object fields to
5983 bitfields where appropriate, remove unused fields.
5984 * window.h (struct window): Remove unused 'last_mark_x' and
5985 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
5986 change it's type from Lisp_Object to bitfield.
5987 Change type of 'force_start', 'optional_new_start',
5988 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
5989 fields from Lisp_Object to bitfield. Adjust users accordingly.
5991 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5993 Pacify gcc -Wdouble-precision when using Xaw.
5994 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
5995 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
5996 Use 'float' consistently, rather than 'float' in most places
5997 and 'double' in a couple of places.
5999 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6001 * xdisp.c (handle_stop): Detect whether we have overlay strings
6002 loaded by testing it->current.overlay_string_index to be
6003 non-negative, instead of checking whether n_overlay_strings is
6004 positive. (Bug#11587)
6006 2012-05-31 Chong Yidong <cyd@gnu.org>
6008 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
6010 * doc.c (Fsubstitute_command_keys): Doc fix.
6012 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6014 * search.c (search_buffer): Remove calls to
6015 r_alloc_inhibit_buffer_relocation, as it is now called by
6016 maybe_unify_char, which was the cause of relocation of buffer text
6019 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6021 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6022 for the duration of call to load_charset, to avoid problems with
6023 callers of maybe_unify_char that access buffer text through C
6026 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6027 decrement the inhibition flag, instead of just setting or
6030 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6032 Remove obsolete '#define static' cruft.
6033 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6034 This #undef was "temporary" in 2000; it is no longer needed
6035 now that '#define static' has gone away.
6036 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6037 (gray_bitmap_bits): Remove; no longer needed.
6038 All uses replaced with definiens.
6039 * xterm.c: Include "bitmaps/gray.xbm".
6041 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6043 Clean up __executable_start, monstartup when --enable-profiling.
6044 The following changes affect the code only when profiling.
6045 * dispnew.c (__executable_start): Rename from safe_bcopy.
6046 Define only on platforms that need it.
6047 * emacs.c: Include <sys/gmon.h> when profiling.
6048 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6049 (__executable_start): Remove decl, since lisp.h does it now.
6050 (safe_bcopy): Remove decl; no longer has that name.
6051 (main): Coalesce #if into single bit of code, for simplicity.
6052 Cast pointers to uintptr_t, since standard libraries want integers
6054 * lisp.h (__executable_start): New decl.
6056 2012-05-31 Glenn Morris <rgm@gnu.org>
6058 * image.c (Fimagemagick_types): Doc fix.
6060 2012-05-30 Jim Meyering <meyering@redhat.com>
6062 * callproc.c (Fcall_process_region): Include directory component
6063 in mkstemp error message (Bug#11586).
6065 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6067 * alloc.c, lisp.h (make_pure_vector): Now static.
6069 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

6074 * data.c (Fdefalias): Purify definition, except for keymaps.
6075 (Qdefun): Move from eval.c.
6076 * lisp.h (Qdefun): Remove.
6077 * lread.c (read1): Tiny simplification.
6079 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
6081 Do not create empty overlays with the evaporate property (Bug#9642).
6082 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6083 Bug#9642, but explicitly check that the buffer the overlay would
6084 be moved to is live and rearrange lines to make sure that errors
6085 will not put the overlay in an inconsistent state.
6086 (Fdelete_overlay): Cosmetics.
6088 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6090 * w32term.c (my_bring_window_to_top): New function.
6091 (x_raise_frame): Use handle returned by DeferWindowPos, which
6092 could be different from the original one.
6093 Call my_bring_window_to_top instead of my_set_foreground_window.
6096 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6097 by calling BringWindowToTop.
6099 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6100 (WM_EMACS_END): Increase by one.
6102 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6104 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6105 This avoids undefined behavior that might cause the eassert
6106 to not catch an out-of-range value.
6108 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6110 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
6111 Update dependencies.
6113 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6115 * bidi.c (bidi_mirror_char): Fix last change.
6117 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
6119 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
6120 when referring to sectname field in printf format.
6122 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
6124 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6125 Only r_alloc_inhibit_buffer_relocation needed to be added;
6126 the others were already declared.
6128 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6129 before checking whether it's out of range. Put the check inside
6131 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6133 2012-05-27 Ken Brown <kbrown@cornell.edu>
6135 * callproc.c (Fcall_process): Restore a line that was accidentally
6136 commented out in the 2011-02-13 change (bug#11547).
6138 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6140 * lisp.h [REL_ALLOC]: Add prototypes for external functions
6141 defined on ralloc.c.
6143 * buffer.c [REL_ALLOC]: Remove prototypes of
6144 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
6145 they are now on lisp.h.
6147 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6149 * search.c (search_buffer): Use it to inhibit relocation of buffer
6150 text while re_search_2 is doing its job, because re_search_2 is
6151 passed C pointers to buffer text. (Bug#11519)
6153 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6156 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6157 state after an additional call to move_it_in_display_line_to, keep
6158 the values of it->max_ascent and it->max_descent found for the
6160 (pos_visible_p): Revert the comparison against bottom_y to what it
6161 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
6164 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6166 Fix coding-related core dumps with gcc -ftrapv.
6167 The code was computing A - B, where A and B are pointers, and B is
6168 random garbage. This can lead to core dumps on platforms that
6169 have special pointer registers, and it also leads to core dumps on
6170 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6171 A - B only when B is initialized properly.
6172 * coding.c (coding_set_source, coding_set_destination): Return void.
6173 (coding_change_source, coding_change_destinations): New functions,
6174 with the old behaviors of coding_set_source and coding_set_destination.
6175 All callers that need an offset changed to use these new functions.
6177 2012-05-26 Glenn Morris <rgm@gnu.org>
6179 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
6181 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6183 Extend mouse support on W32 text-mode console.
6184 * xdisp.c (draw_row_with_mouse_face):
6185 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6187 * w32console.c: Include window.h.
6188 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6190 (initialize_w32_display): Initialize mouse-highlight data.
6192 * w32inevt.c: Include termchar.h and window.h.
6193 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6194 moves, call note_mouse_highlight. If help_echo changed, call
6195 gen_help_event to produce help-echo message in the echo area.
6196 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6199 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6201 * lread.c (read1): Simplify slightly to avoid an overflow warning
6202 with GCC 4.7.0 on x86-64.
6204 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6206 * bidi.c (bidi_mirror_char): Revert last change: an int is
6207 definitely wide enough here.
6209 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
6211 Fix integer width and related bugs (Bug#9874).
6212 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
6213 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
6214 (string_bytes, check_sblock, allocate_string_data):
6215 (compact_small_strings, Fmake_bool_vector, make_string)
6216 (make_unibyte_string, make_multibyte_string)
6217 (make_string_from_bytes, make_specified_string)
6218 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
6219 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
6221 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6222 (allocate_pseudovector):
6223 Use int, not EMACS_INT, where int is wide enough.
6224 (inhibit_garbage_collection, Fgarbage_collect):
6225 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6226 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
6227 int might not be wide enough.
6228 (bidi_cache_search, bidi_cache_find, bidi_init_it)
6229 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6230 (bidi_at_paragraph_end, bidi_find_paragraph_start)
6231 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
6232 (bidi_level_of_next_char, bidi_move_to_visually_next):
6233 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6234 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
6235 (Fkill_buffer, Fset_buffer_major_mode)
6236 (advance_to_char_boundary, Fbuffer_swap_text)
6237 (Fset_buffer_multibyte, overlays_at, overlays_in)
6238 (overlay_touches_p, struct sortvec, record_overlay_string)
6239 (overlay_strings, recenter_overlay_lists)
6240 (adjust_overlays_for_insert, adjust_overlays_for_delete)
6241 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
6242 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
6243 (Foverlay_recenter, last_overlay_modification_hooks_used)
6244 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6245 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6246 (validate_region): Omit unnecessary test for b <= e,
6247 since that's guaranteed by the previous test.
6248 (adjust_overlays_for_delete): Avoid pos + length overflow.
6249 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6250 (report_overlay_modification):
6251 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6252 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
6253 Omit pointer cast, which isn't needed anyway, and doesn't work
6254 after the EMACS_INT -> ptrdiff_t change.
6255 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
6256 * buffer.h: Adjust decls to match defn changes elsewhere.
6257 (struct buffer_text, struct buffer):
6258 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6259 Use EMACS_INT, not int, where int might not be wide enough.
6260 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
6261 not int, to avoid needless 32-bit limit on 64-bit hosts.
6262 (exec_byte_code): Use tighter memory-full test, one that checks
6263 for alloca overflow. Don't compute the address of the object just
6264 before an array, as that's not portable. Use EMACS_INT, not
6265 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
6266 * callint.c (Fcall_interactively):
6267 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6268 * callproc.c (call_process_kill, Fcall_process):
6269 Don't assume pid_t fits into an Emacs fixnum.
6270 (call_process_cleanup, Fcall_process, child_setup):
6271 Don't assume pid_t fits into int.
6272 (call_process_cleanup, Fcall_process, delete_temp_file)
6273 (Fcall_process_region):
6274 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6275 (Fcall_process): Simplify handling of volatile integers.
6276 Use int, not EMACS_INT, where int will do.
6277 * casefiddle.c (casify_object, casify_region, operate_on_word)
6278 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
6279 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6280 (casify_object): Avoid integer overflow when overallocating buffer.
6281 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
6282 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
6283 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
6284 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6285 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6286 integers are now checked earlier. All uses replaced with XINT.
6288 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6289 For CCL_MapSingle, check that content and value are in int range.
6290 (ccl_driver, Fregister_code_conversion_map):
6291 Check that Vcode_version_map_vector is a vector.
6292 (resolve_symbol_ccl_program): Check that vector header is in range.
6293 Always copy the vector, so that we can check its contents reliably
6294 now rather than having to recheck each instruction as it's being
6295 executed. Check that vector words fit in 'int'.
6296 (ccl_get_compiled_code, Fregister_ccl_program)
6297 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6298 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
6299 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
6300 contents are in range.
6301 (Fccl_execute_on_string): Check that status is in range.
6302 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
6303 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
6304 Accept and return EMACS_INT, not int, because callers can pass values
6306 (c_string_width, strwidth, lisp_string_width, chars_in_text)
6307 (multibyte_chars_in_text, parse_str_as_multibyte)
6308 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
6309 (str_as_unibyte, str_to_unibyte, string_count_byte8)
6310 (string_escape_byte8, Fget_byte):
6311 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6312 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
6313 avoid mishandling large integers.
6314 * character.h: Adjust decls to match defn changes elsewhere.
6315 * charset.c (load_charset_map_from_file, find_charsets_in_text)
6316 (Ffind_charset_region):
6317 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6318 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
6319 (load_charset_map_from_vector, Fdefine_charset_internal):
6320 Don't assume fixnum fits in int.
6321 (load_charset_map_from_vector, Fmap_charset_chars):
6322 Remove now-unnecessary CHECK_NATNUMs.
6323 (Fdefine_charset_internal): Check ranges here, more carefully.
6324 Don't rely on undefined behavior with signed left shift overflow.
6325 Don't assume unsigned int fits into fixnum, or that fixnum fits
6326 into unsigned int. Don't require max_code to be a valid fixnum;
6327 that's not true for gb10830 4-byte on a 32-bit host. Allow
6328 invalid_code to be a cons, for the same reason. Require code_offset
6329 to be a character. Avoid int overflow if max_char is close
6331 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
6332 this is intended anyway and avoids some undefined behavior.
6333 (load_charset_map): Pass unsigned, not int, as 2nd arg of
6334 INDEX_TO_CODE_POINT, as that's what it expects.
6335 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
6336 * charset.h (DECODE_CHAR): Return int, not unsigned;
6337 this is what was intended anyway, and it avoids undefined behavior.
6338 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
6339 integer-overflow issues.
6340 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
6341 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
6342 where the argument is EMACS_INT, and this behavior is not intended.
6343 * chartab.c (Fmake_char_table, Fset_char_table_range)
6344 (uniprop_get_decoder, uniprop_get_encoder):
6345 Don't assume fixnum fits in int.
6346 * cmds.c (move_point): New function, that does the gist of
6347 Fforward_char and Fbackward_char, but does so while checking
6348 for integer overflow more accurately.

7059 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
7060 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
7061 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
7062 * s/ms-w32.h (DATA_START):
7063 Move here from removed file m/intel386.h.
7064 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
7065 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
7067 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
7069 Assume C89 or later.
7070 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
7071 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
7073 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
7074 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
7075 * textprop.c, tparam.c (NULL): Remove.
7076 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
7077 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
7078 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
7079 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
7080 * xterm.c (input_signal_count): Assume volatile works.
7082 2012-05-21 Ken Brown <kbrown@cornell.edu>
7084 * xgselect.c (xg_select): Fix first argument in call to 'select'
7087 2012-05-20 Ken Brown <kbrown@cornell.edu>
7089 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
7090 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
7092 2012-05-19 Ken Brown <kbrown@cornell.edu>
7094 * xfns.c (x_in_use): Remove `static' qualifier.
7095 * xterm.h (x_in_use): Declare.
7096 * xgselect.c: Include xterm.h.
7097 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
7098 and `display_arg' (bug#9754).
7100 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
7102 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
7104 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
7105 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
7107 2012-05-18 Eli Zaretskii <eliz@gnu.org>
7109 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
7111 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
7112 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
7114 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
7115 reference to image_cache->refcount.
7116 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
7118 2012-05-17 Juri Linkov <juri@jurta.org>
7120 * search.c (Fword_search_regexp, Fword_search_backward)
7121 (Fword_search_forward, Fword_search_backward_lax)
7122 (Fword_search_forward_lax): Move functions to isearch.el
7123 (bug#10145, bug#11381).
7125 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
7127 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
7129 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
7131 * lread.c (init_obarray): Declare Qt and Qnil as special.
7133 2012-05-14 Glenn Morris <rgm@gnu.org>
7135 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
7136 Put "libexec" before "bin", for the sake of init_callproc_1.
7138 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7140 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
7142 * unexaix.c: Port to more-recent AIX compilers.
7143 (report_error, report_error_1, make_hdr, copy_sym)
7144 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
7145 Make arguments const char *, not char *, to avoid violations of C
7146 standard and to fix some AIX warnings reported by Gilles Pion.
7148 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7150 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
7151 already have overlays loaded.
7152 (handle_single_display_spec): Before returning without displaying
7153 fringe bitmap, synchronize the bidi iterator with the main display
7154 iterator, by calling iterate_out_of_display_property.
7155 (iterate_out_of_display_property): Detect buffer iteration by
7156 testing that it->string is a Lisp string.
7157 (get_next_display_element): When the current object is exhausted,
7158 and there's something on it->stack, call set_iterator_to_next to
7159 proceed with what's on the stack, instead of returning zero.
7160 (set_iterator_to_next): If called at the end of a Lisp string,
7161 proceed to consider_string_end without incrementing string
7162 position. Don't increment display vector index past the end of
7163 the display vector. (Bug#11417)
7164 (pos_visible_p): Don't report a position visible when move_it_to
7165 stopped at the last line of window, which happens to be scanned
7166 backwards by the bidi iteration. (Bug#11464)
7168 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7170 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7171 and right-margin display specs even if the spec is invalid or we
7172 are on a TTY, and thus unable to display on the fringes.
7173 That's because the text with the property will not be displayed anyway,
7174 so we need to signal to the caller that this is a "replacing"
7175 display spec. This fixes display when the spec is invalid or we
7178 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7180 * unexaix.c (make_hdr): Fix typo in prototype.
7181 This bug broke the build on AIX. Problem reported by Gilles Pion.
7183 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
7185 * keyboard.c (kbd_buffer_get_event): Read special events also in
7186 batch mode. (Bug#11415)
7188 2012-05-12 Glenn Morris <rgm@gnu.org>
7190 * ns.mk: Update for ns_appbindir no longer having trailing "/".
7192 2012-05-12 Eli Zaretskii <eliz@gnu.org>
7194 * lisp.mk (lisp): Add newcomment.elc.
7196 2012-05-12 Glenn Morris <rgm@gnu.org>
7198 * Makefile.in (MKDIR_P): New, set by configure.
7199 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
7201 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
7203 Remove unused function hourglass_started.
7204 * dispextern.h (hourglass_started):
7205 * w32fns.c (hourglass_started):
7206 * xdisp.c (hourglass_started): Remove.
7208 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7210 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7211 Update dependencies.
7213 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7215 * xgselect.c (xg_select): Put maxfds+1 into a var.
7216 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
7218 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7220 2012-05-10 Dave Abrahams <dave@boostpro.com>
7222 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7223 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7225 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7227 * dbusbind.c (xd_registered_buses): New internal Lisp object.
7228 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7229 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7230 Initialize xd_registered_buses.
7232 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7234 Untag more efficiently if USE_LSB_TAG.
7235 This is based on a proposal by YAMAMOTO Mitsuharu in
7236 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7237 For an admittedly artificial (nth 8000 longlist) benchmark on
7238 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7239 Emacs's overall text size by 1%.
7240 * lisp.h (XUNTAG): New macro.
7241 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7242 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7243 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7244 * eval.c (Fautoload):
7245 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7246 * frame.h (XFRAME): Use XUNTAG.
7248 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7249 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7250 Remove unportable assumptions about print widths of types like
7252 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7253 intptr_t when converting between pointer and integer, to avoid GCC
7254 warnings about wrong width.
7256 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7258 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7259 stack for each reader_thread, instead of defaulting to 8MB
7260 determined by the linker. This avoids failures in creating
7261 subprocesses on Windows 7, see the discussion in this thread:
7262 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7264 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7266 Fix up display of the *Minibuf-0* buffer in the mini window.
7267 * keyboard.c (read_char): Don't clear the echo area if there's no
7269 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7270 contents of *Minibuf-0*) if there's no message displayed in its stead.
7272 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7274 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7277 2012-05-06 Chong Yidong <cyd@gnu.org>
7279 * lisp.mk (lisp): Update.
7281 2012-05-05 Jim Meyering <meyering@redhat.com>
7283 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7285 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7287 * data.c (PUT_ERROR): New macro.
7288 (syms_of_data): Use it. Add new error type `user-error'.
7289 * undo.c (user_error): New function.
7290 (Fprimitive_undo): Use it.
7291 * print.c (print_error_message): Adjust print style for `user-error'.
7292 * keyboard.c (user_error): New function.
7293 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7295 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7297 Do not limit current-time-string to years 1000..9999.
7298 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7299 (Fcurrent_time_string): Support any year that is supported by the
7300 underlying localtime representation. Don't use asctime, as it
7301 has undefined behavior for years outside the range -999..9999.
7303 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7305 Fix race conditions involving setenv, gmtime, localtime, asctime.
7306 Without this fix, interrupts could mess up code that uses these
7307 nonreentrant functions, since setting TZ invalidates existing
7308 tm_zone or tzname values, and since most of these functions return
7309 pointers to static storage.
7310 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7311 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7312 Grow the critical sections to include not just invoking
7313 localtime/gmtime, but also accessing these functions' results
7314 including their tm_zone values if any, and any related TZ setting.
7315 (format_time_string): Last arg is now struct tm *, not struct tm **,
7316 so that the struct tm is saved in the critical section.
7317 All callers changed. Simplify allocation of initial buffer, partly
7318 motivated by the fact that memory allocation needs to be outside
7319 the critical section.
7321 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7323 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7324 with RESET_INTERVAL.
7326 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7327 Remove duplicated buffer name initialization.
7329 2012-05-02 Jim Meyering <jim@meyering.net>
7331 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7333 * xfns.c (x_window): Use xstrdup (Bug#11375).
7335 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7337 * xdisp.c (pos_visible_p): If already at a newline from the
7338 display string before the 'while' loop, don't walk back the glyphs
7339 from it3.glyph_row. Solves assertion violation when the display
7340 string begins with a newline (egg.el). (Bug#11367)
7342 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7344 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7347 2012-05-01 Glenn Morris <rgm@gnu.org>
7349 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7350 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7351 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7352 All were removed before 23.1.
7354 * dispnew.c: Remove HAVE_LIBNCURSES test;
7355 it is always true on relevant platforms.
7357 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7358 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7360 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
7362 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
7364 * .gdbinit (xpr): Remove checks for no longer existing misc types.
7365 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
7368 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
7370 Do not avoid creating empty evaporating overlays (Bug#9642).
7371 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7372 That is, do not delete an evaporating overlay if it becomes
7373 empty after its bounds are adjusted to fit within its buffer.
7374 This fix caused other problems, and I'm reverting it until we get
7375 to the bottom of them.
7377 2012-04-27 Chong Yidong <cyd@gnu.org>
7379 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7381 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7383 * xdisp.c (pos_visible_p): If the window start position is beyond
7384 ZV, start the display from buffer beginning. Prevents assertion
7385 violation in init_iterator when the minibuffer window is scrolled
7388 * window.c (window_scroll_pixel_based): Likewise.
7390 2012-04-27 Chong Yidong <cyd@gnu.org>
7392 * keymap.c (where_is_internal): Doc fix (Bug#10872).
7394 2012-04-27 Glenn Morris <rgm@gnu.org>
7396 * fileio.c (Fcopy_file, Fset_file_selinux_context):
7397 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
7399 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7401 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
7402 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
7404 2012-04-26 Eli Zaretskii <eliz@gnu.org>
7406 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7407 display element, check also the underlying string or buffer
7408 character. (Bug#11341)
7410 * w32menu.c: Include w32heap.h.
7411 (add_menu_item): If the call to AppendMenuW (via
7412 unicode_append_menu) fails, disable Unicode menus only if we are
7413 running on Windows 9X/Me.
7415 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7417 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
7418 (xgetint): Add missing shift for LSB tags.
7420 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7422 * keyboard.c (read_char): Don't wipe echo area for select window
7423 events: These might get delayed via `mouse-autoselect-window'
7426 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
7428 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
7429 manipulation of :loaded-from data.
7431 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
7433 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
7434 now a cons (bug#11311).
7436 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7438 Do not create empty overlays with the evaporate property (Bug#9642).
7439 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7440 if it becomes empty after its bounds are adjusted to fit within
7441 its buffer. Without this fix, in a nonempty buffer (let ((o
7442 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7443 yields an empty overlay that has the evaporate property, which is
7444 not supposed to happen.
7446 Fix minor GTK3 problems found by static checking.
7447 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7448 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7449 (struct _EmacsFixedClass, emacs_fixed_get_type):
7450 Move decls here from emacsgtkfixed.h, since they needn't be public.
7451 (emacs_fixed_get_type): Now static.
7452 (emacs_fixed_class_init): Omit unused local.
7453 (emacs_fixed_child_type): Remove; unused.

7455 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7456 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
7457 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
7458 (EMACS_FIXED_GET_CLASS): Remove; unused.
7459 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
7461 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
7462 Problem reported by Juanma Barranquero for Windows -Wunused-function.
7464 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7466 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
7467 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
7468 (__malloc_size_t, __malloc_ptrdiff_t):
7469 Remove. All uses removed, replaced by the definiens if needed,
7470 since we can assume C89 or better now.
7471 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
7472 (protect_malloc_state, align, get_contiguous_space)
7473 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
7474 (malloc_atfork_handler_child, malloc_enable_thread)

7479 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
7480 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
7481 Define using prototypes, not old style.
7482 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
7483 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
7484 (align): Don't assume that signed integer overflow wraps around.
7485 Omit unused local var.
7486 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
7487 (_free_internal_nolock, memalign, mallochook, reallochook):
7488 Omit no-longer-needed casts.
7489 (valloc): Use getpagesize, not __getpagesize.
7490 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
7491 (struct hdr): The 'magic' member is now size_t, not unsigned long.
7493 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
7495 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
7497 Move functions from C to Lisp. Make non-blocking method calls
7498 the default. Implement further D-Bus standard interfaces.
7500 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
7501 (QCdbus_request_name_allow_replacement)
7502 (QCdbus_request_name_replace_existing)
7503 (QCdbus_request_name_do_not_queue)

7507 (QCdbus_request_name_reply_already_owner): Move to dbus.el.
7508 (QCdbus_registered_serial, QCdbus_registered_method)
7509 (QCdbus_registered_signal): New Lisp objects.
7510 (XD_DEBUG_MESSAGE): Use sizeof.

7546 * alloc.c: Handle unusual debugging option combinations.
7547 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
7548 since the two debugging options are incompatible.
7549 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7551 (mem_init, mem_insert, mem_insert_fixup):
7552 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

7584 (print_object): Check for cycles even when print-circle is nil and
7585 print-gensym is t, but only check print_depth if print-circle is nil.
7587 2012-04-20 Chong Yidong <cyd@gnu.org>
7589 * process.c (wait_reading_process_output): If EIO occurs on a pty,

7645 New extern decls, to avoid calling undeclared functions.
7646 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
7647 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
7648 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

7689 Remove definition of GC_MARK_STACK, since the default now works.
7690 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
7691 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
7692 no longer the default.
7693 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
7695 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

7718 2012-04-11 Daniel Colascione <dancol@dancol.org>
7720 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
7721 against is gone. It's better to use vfork now so that when Cygwin
7722 gains a new, working vfork, we use it automatically (bug#10398).
7724 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

7745 being loaded (bug#10424).
7747 2012-04-09 Glenn Morris <rgm@gnu.org>
7749 * doc.c (Fsnarf_documentation): Check variables, functions are bound,

7777 * minibuf.c (Fread_variable): Callers changed.
7779 2012-04-09 Eli Zaretskii <eliz@gnu.org>
7781 * xdisp.c (set_cursor_from_row): If the display string appears in
7782 the buffer at position that is closer to point than the position
7783 after the display string, display the cursor on the first glyph of
7784 the display string. Fixes cursor display when a 'display' text
7785 property immediately follows invisible text. (Bug#11094)
7787 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
7789 composite.c: use 'double' consistently
7790 * composite.c (get_composition_id): Use 'double' consistently
7791 instead of converting 'float' to 'double' and vice versa; this is
7792 easier to understand and avoids a GCC warning.
7794 2012-04-09 Glenn Morris <rgm@gnu.org>
7796 * Makefile.in: Generate leim-list with bootstrap-emacs, in
7797 preparation for dumping it with emacs. (Bug#4789)

7839 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
7840 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
7841 [!WINDOWSNT]: New macros.
7842 (init_libxml2_functions, libxml2_loaded_p): New functions.
7843 (parse_region): Call fn_xmlCheckVersion instead of using the macro
7844 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
7845 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
7846 Calls xmlCleanupParser only if libxml2 was loaded (or statically
7848 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
7849 Call init_libxml2_functions before calling libxml2 functions.
7850 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
7852 * emacs.c: Don't include libxml/parser.h.

7866 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
7867 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
7868 about subtle differences between FETCH_CHAR* and STRING_CHAR*
7869 macros related to unification of CJK characters. For the details,
7870 see the discussion following the message here:
7871 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
7873 2012-04-04 Chong Yidong <cyd@gnu.org>
7875 * keyboard.c (Vdelayed_warnings_list): Doc fix.

7887 2012-03-31 Eli Zaretskii <eliz@gnu.org>
7889 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
7890 position we get to after a call to move_it_to fails the
7891 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
7892 only if we wind up in a string from display property. (Bug#11063)
7894 * window.c (Fdelete_other_windows_internal): Invalidate the row
7895 and column information about mouse highlight, so that redisplay
7896 restores it after reallocating the glyph matrices. (Bug#7464)
7898 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
7899 string comes from a `display' text property, use the buffer
7900 position of that property as if we actually saw that position in
7902 (move_it_by_lines): Remove the assertion that
7903 "it->current_x == 0 && it->hpos == 0" which can be legitimately
7904 violated when there's a before-string at the beginning of a line.
7907 2012-03-30 Eli Zaretskii <eliz@gnu.org>
7909 * xdisp.c (append_space_for_newline): If the default face was
7910 remapped, use the remapped face for the appended newline.
7911 (extend_face_to_end_of_line): Use the remapped default face for
7912 extending the face to the end of the line.
7913 (display_line): Call extend_face_to_end_of_line when the default
7914 face was remapped. (Bug#11068)
7916 2012-03-29 Eli Zaretskii <eliz@gnu.org>

7940 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
7942 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.

7949 2012-03-24 Eli Zaretskii <eliz@gnu.org>
7951 * s/ms-w32.h (tzname): Include time.h before redirecting to

7962 2012-03-23 Eli Zaretskii <eliz@gnu.org>
7964 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
7965 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
7966 when fetching a multibyte character consumes more bytes than
7967 CHAR_BYTES returns, due to unification of CJK characters in
7968 string_char. (Bug#11073)
7970 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
7972 * process.c (wait_reading_process_output): Handle pty disconnect
7973 by refraining from sending oneself a SIGCHLD (bug#10933).

7996 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
7997 to reflect default non-nil value of redisplay-dont-pause.
7999 2012-03-19 Kenichi Handa <handa@m17n.org>
8001 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
8002 it fit in a valid range (Bug#11003).
8004 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8006 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8007 that is not from display property, accept the row as a "cursor
8008 row" if one of the string's character has a non-nil `cursor'
8009 property. Fixes cursor positioning when there are newlines in
8010 overlay strings, e.g. in icomplete.el. (Bug#11035)
8012 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

8043 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8046 2012-03-03 Glenn Morris <rgm@gnu.org>
8048 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

8061 * buffer.c (buffer-list-update-hook): Doc fix.
8063 2012-02-29 Eli Zaretskii <eliz@gnu.org>

8066 push_it before setting up the iterator for the first overlay
8067 string, even if we have an empty string loaded.
8068 (next_overlay_string): If there's an empty string on the iterator
8069 stack, pop the stack. (Bug#10903)
8071 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8073 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8074 Suggested by Stefan Monnier in
8075 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8076 * alloc.c (widen_to_Lisp_Object): New static function.
8077 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8078 and widening them to Lisp_Objects. This would work even if
8079 USE_LSB_TAG is defined and wide integers are used, which might
8080 happen in a future version of Emacs.
8082 2012-02-25 Chong Yidong <cyd@gnu.org>
8084 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

8098 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
8099 call when setting menu-bar-lines and tool-bar-lines parameters.
8100 (unwind_create_frame_1): New helper function.
8102 * window.c (inhibit_window_configuration_change_hook): New var.
8103 (run_window_configuration_change_hook): Obey it.
8104 (syms_of_window): Initialize it.
8106 2012-02-22 Chong Yidong <cyd@gnu.org>
8108 * xterm.c (x_draw_image_relief): Add missing type check for

8121 when computing $valmask.
8123 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8124 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8125 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8126 It's useless in that case, and it can cause problems on hosts
8127 that allocate halves of EMACS_INT values separately.
8128 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8129 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8130 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8131 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8132 it avoids undefined behavior on hosts where shifting right by more
8133 than the word width has undefined behavior.
8135 2012-02-19 Chong Yidong <cyd@gnu.org>
8137 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
8138 (Funhandled_file_name_directory, Ffile_name_as_directory)

8157 2012-02-15 Chong Yidong <cyd@gnu.org>
8159 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
8160 marked as special. Also, starting docstrings with * is obsolete.

8177 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
8178 as that creates a dangerous corner case.
8180 * window.c (Fdelete_window_internal): Invalidate the mouse
8181 highlight (Bug#9904).
8183 2012-02-12 Glenn Morris <rgm@gnu.org>

8188 * nsselect.m (Fx_own_selection_internal)
8189 (Fx_disown_selection_internal, Fx_selection_exists_p)
8190 (Fx_selection_owner_p, Fx_get_selection_internal):
8191 Sync docs and argument specs with the xselect.c versions.

8213 2012-02-07 Chong Yidong <cyd@gnu.org>
8215 * buffer.c (Fbuffer_local_variables)
8216 (buffer_lisp_local_variables): Handle unbound vars correctly;
8217 don't let Qunbound leak into Lisp.
8219 2012-02-07 Glenn Morris <rgm@gnu.org>
8221 * image.c (Fimagemagick_types): Doc fix.
8223 * image.c (imagemagick-render-type): Change it from a lisp object

8229 * doc.c (store_function_docstring): Avoid applying docstring of
8230 alias to base function (Bug#2603).

8256 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
8258 Handle overflow when computing char display width (Bug#9496).
8259 * character.c (char_width): Return EMACS_INT, not int.
8260 (char_width, c_string_width): Check for overflow when
8261 computing the width; this is possible now that individual
8262 characters can have unbounded width. Problem introduced
8263 by merge from Emacs 23 on 2012-01-19.
8265 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

8294 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
8295 first 2 arguments are identical. This makes inserting large
8296 output from a subprocess an order of magnitude faster on
8297 MS-Windows, where all sbrk'ed memory is always contiguous.

8403 emacs: fix an auto-save permissions race condition (Bug#10400)
8404 * fileio.c (auto_saving_dir_umask): New static var.
8405 (Fmake_directory_internal): Use it.
8406 (do_auto_save_make_dir): Set it, instead of invoking chmod after
8407 creating the directory. The old code temporarily assigns
8408 too-generous permissions to the directory.
8409 (do_auto_save_eh): Clear it.
8410 (Fdo_auto_save): Catch all errors, not just file errors, so
8411 that the var is always cleared.

8415 * search.c (scan_buffer): Pass character positions to
8416 know_region_cache, not byte positions. (Bug#6540)

8468 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
8469 property that ends at ZV, so that the bidi iteration could be

8917 is set, removing the need for VIRT_ADDRESS_VARIES.
8918 (PURE_P): Use a more-efficient implementation that needs just one

8935 behave as if the cursor position were at the window margin.
8937 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
8938 and the cursor position is out of bounds, behave as if the cursor
8939 position were at the window margin. (Bug#10075)

8969 * dispnew.c (verify_row_hash): Call row_hash for computing the
8970 hash code of a row, instead of duplicating code from xdisp.c.
8972 * dispextern.h (row_hash): Add prototype.

9446 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
9448 * w32fns.c (w32_default_color_map): New function,
9449 extracted from Fw32_default_color_map.
9450 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
9452 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
9454 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
9456 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
9458 * keyboard.c (test_undefined): New function (bug#9751).
9459 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
9461 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
9463 * sysdep.c (init_sys_modes): Fix the check for the controlling
9464 terminal (Bug#6649).
9466 2011-10-20 Eli Zaretskii <eliz@gnu.org>
9468 * dispextern.h (struct bidi_it): New member next_en_type.
9470 * bidi.c (bidi_line_init): Initialize the next_en_type member.
9471 (bidi_resolve_explicit_1): When next_en_pos is valid for the
9472 current character, check also for next_en_type being WEAK_EN.
9473 (bidi_resolve_weak): Don't enter the expensive loop if the current
9474 position is before next_en_pos. Record the bidi type of the first
9475 non-ET, non-BN character we find, in addition to its position.
9476 (bidi_level_of_next_char): Invalidate next_en_type when
9477 next_en_pos is over-stepped.
9479 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
9481 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
9482 * editfns.c: Rewrite current-time-zone so that it invokes
9483 the equivalent of (format-time-string "%Z") to get the time zone name.
9484 This fixes a bug when the time zone name contains characters that
9485 need converting from the system time locale to Emacs internal format.
9486 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9487 that patch fixed format-time-string to do the conversion, but
9488 I forgot to fix current-time-zone.
9489 (format_time_string): New function, containing most of
9490 what Fformat_time_string used to contain.
9491 (Fformat_time_string): Rewrite in terms of format_time_string.
9492 This doesn't change this function's behavior.
9493 (current-time-zone): Rewrite to use format_time_string.
9494 This fixes the bug reported by Michael Schierl in
9495 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9496 Jason Rumney's 2007-06-07 change worked around this bug, but
9498 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9500 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9502 * xdisp.c (start_display): If the character at POS is displayed
9503 via a display vector, reset IT->current.dpvec_index to zero.
9504 (try_window_reusing_current_matrix): If a line ends in a display
9505 vector or the next line starts in a display vector, continue
9506 redrawing the window even though the character position of
9507 start_row was reached.
9510 2011-10-18 Chong Yidong <cyd@gnu.org>
9512 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9513 with nobreak-char-display too.
9515 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9517 Fix part 3 of bug#9771.
9518 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9519 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9520 non-neutral characters if the current character is a paragraph
9521 separator (a.k.a. Newline). This avoids running the same
9522 expensive loop twice, once when we consume the preceding newline
9523 and the other time when the line actually needs to be displayed.
9524 Avoid the loop when we see neutrals on the base embedding level
9525 following a character whose directionality is the same as the
9526 paragraph's. This avoids running the expensive loop when a line
9527 ends in a long sequence of neutrals, like control characters.
9528 Add assertion against STRONG_AL type. Slightly rearrange code
9529 that determines the type of a neutral given the first non-neutral
9531 (bidi_level_of_next_char): Set next_en_pos to zero when
9532 invalidating its info.
9534 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9536 * xdisp.c (push_display_prop): Determine whether to record string
9537 or buffer position by IT->string, not by IT->method. Allow
9538 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9539 (move_it_vertically_backward): Don't look for character position
9540 immediately after the newline when in a continuation line.
9543 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9545 * window.c (coordinates_in_window): Rewrite and delabelize
9546 vertical border check. (Bug#5357) (Bug#9618)
9548 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9550 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9551 errors in XSetWindowBorder (bug#9310).
9553 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9555 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9556 avoid crash when xmalloc overrun checking is enabled.
9558 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9560 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9561 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9562 cursor motion with <left> and <right> arrow keys.
9564 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9565 some callers set that themselves.
9567 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9569 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9570 display string and the previous row comes from the same string and
9571 is empty. (Bug#9739) (Bug#9738)
9573 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9575 * doc.c (get_doc_string): Encode file name (bug#9735).
9577 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9579 * bidi.c (bidi_level_of_next_char):
9580 * xdisp.c (get_visually_first_element): Remove old incorrect
9581 comments regarding the Unicode Line Separator character.
9583 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9585 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9587 * alloc.c (Fgc_status): Do not access beyond zombies array
9588 boundary if nzombies > MAX_ZOMBIES.
9589 * alloc.c (dump_zombies): Add missing format specifier.
9591 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9593 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9594 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9596 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9597 Some packages use them to denote characters with modifiers.
9599 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9601 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9602 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9603 matching a pp-number. Rename parameter var to var1.
9605 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9607 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9609 2011-10-08 Glenn Morris <rgm@gnu.org>
9611 * callint.c (Fcall_interactively): Give a more explicit error for the
9612 'c' case with a non-character input. (Bug#8479)
9614 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9616 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9618 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9619 lines that are hscrolled on the left.
9621 * dispnew.c (buffer_posn_from_coords): Account for a possible
9622 presence of header-line. (Bug#4426)
9624 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
9626 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
9627 Don't advertise functionality which we discourage or doesn't work.
9629 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
9631 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
9632 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
9633 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
9634 this makes Emacs dump core during garbage collection on rare
9635 occasions. sizeof is obviously inferior to offsetof here, so
9636 stick with offsetof.
9637 (GC_POINTER_ALIGNMENT): New macro.
9638 (mark_memory): Omit 3rd (offset) arg; caller changed.
9639 Don't assume EMACS_INT alignment is the same as pointer alignment.
9641 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
9643 * keyboard.c (read_key_sequence_remapped): New var.
9644 (read_key_sequence): Compute remapping in the right buffer.
9645 (command_loop_1): Use read_key_sequence's remapping directly.
9647 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
9649 * dired.c (file_name_completion): Don't expand file name.
9650 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
9651 before checking file name handler.
9653 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
9654 they've been requested explicitly (bug#9591).
9656 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
9658 * keymap.c (Fsingle_key_description): Use make_specified_string
9659 instead of build_string to build string from push_key_description.
9662 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9664 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
9665 This fixes a Y2038 bug on 64-bit hosts.
9666 * buffer.c (reset_buffer):
9667 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
9668 (Fclear_buffer_auto_save_failure):
9669 Use 0, not -1, to represent an unset failure time, since time_t
9670 might not be signed.
9672 Remove dependency on glibc malloc internals.
9673 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9674 Move back here from lisp.h, but with their new implementations.
9675 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9676 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
9677 * charset.c (charset_table_init): New static var.
9678 (syms_of_charset): Use it instead of xmalloc. This removes a
9679 dependency on glibc malloc internals. See Eli Zaretskii's comment in
9680 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
9681 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9682 Move back to alloc.c.
9683 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9684 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
9686 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
9688 * nsterm.m (windowDidResize): Call x_set_window_size only when
9689 ns_in_resize is true. Otherwise set pixelwidth/height and
9690 call change_frame_size (Bug#9628).
9692 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9694 Port --enable-checking=all to Fedora 14 x86-64.
9695 * charset.c (syms_of_charset): Also account for glibc malloc's
9696 internal overhead when calculating the initial malloc maximum.
9698 Port --enable-checking=all to Fedora 14 x86.
9699 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9701 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
9702 (overrun_check_realloc, overrun_check_free):
9703 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
9704 That way, xmalloc returns a properly-aligned pointer even if
9705 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
9706 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
9707 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
9708 into account when calculating the initial malloc maximum.
9709 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9710 Move here from alloc.c, so that charset.c can use it too.
9711 Properly align; the old code wasn't right for common 32-bit hosts
9712 when configured with --enable-checking=all.
9713 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9714 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
9716 2011-09-29 Eli Zaretskii <eliz@gnu.org>
9718 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
9721 2011-09-28 Eli Zaretskii <eliz@gnu.org>
9723 * xdisp.c (compute_display_string_end): If there's no display
9724 string at CHARPOS, return -1.
9726 * bidi.c (bidi_fetch_char): When compute_display_string_end
9727 returns a negative value, treat the character as a normal
9728 character not covered by a display string. (Bug#9624)
9730 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
9732 * lread.c (Fread_from_string): Fix typo in docstring.
9734 2011-09-27 Eli Zaretskii <eliz@gnu.org>
9736 * xdisp.c (handle_invisible_prop): If invisible text ends on a
9737 newline, reseat the iterator instead of bidi-iterating there one
9738 character at a time. (Bug#9610)
9739 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
9740 TO_CHARPOS if the bidi iterator is at base embedding level.
9742 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
9744 * lread.c (readevalloop): Use correct code for NBSP.
9745 (read1): Likewise. (Bug#9608)
9747 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
9749 * dbusbind.c (Fdbus_register_signal): When service is not
9750 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
9752 2011-09-25 Glenn Morris <rgm@gnu.org>
9754 * buffer.c (truncate-lines): Doc fix.
9756 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
9758 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
9759 (Fset_window_next_buffers): Doc fix.
9761 2011-09-24 Glenn Morris <rgm@gnu.org>
9763 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
9765 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
9767 Fix minor problems found by static checking.
9768 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
9769 * indent.c (Fvertical_motion): Fix == vs = typo.
9771 2011-09-24 Eli Zaretskii <eliz@gnu.org>
9773 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
9774 Default value is now t. Doc fix.
9776 * indent.c (Fvertical_motion): Compute and apply the overshoot
9777 logic when moving up, not only when moving down. Fix the
9778 confusing name and values of the it_overshoot_expected variable;
9779 logic changes accordingly. (Bug#9254) (Bug#9549)
9781 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
9782 CHARPOS is covered by a display string which includes newlines.
9783 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
9784 is covered by a display string with embedded newlines.
9786 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
9788 * dbusbind.c (Fdbus_register_signal): Add match rule to
9789 Vdbus_registered_objects_table. (Bug#9581)
9790 (Fdbus_register_method, Vdbus_registered_objects_table):
9793 2011-09-24 Jim Meyering <meyering@redhat.com>
9795 do not ignore write error for any output size
9796 The previous change was incomplete.
9797 While it makes emacs --batch detect the vast majority of stdout
9798 write failures, errors were still ignored whenever the output size is
9799 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
9800 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
9801 && echo FAIL: ignored write error
9802 FAIL: ignored write error
9803 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
9804 && echo FAIL: ignored write error
9805 FAIL: ignored write error
9806 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
9808 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
9810 * emacs.c (Fkill_emacs): In noninteractive mode exit
9811 non-successfully if a write error occurred on stdout. (Bug#9574)
9813 2011-09-21 Eli Zaretskii <eliz@gnu.org>
9815 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
9818 * dispextern.h (struct it): Update the comment documenting what
9821 2011-09-20 Eli Zaretskii <eliz@gnu.org>
9823 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
9824 a display string, extend search for cursor position to end of row.
9825 (find_row_edges): If the row ends in a newline from a display
9826 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
9827 Handle the case of a display string with multiple newlines.
9828 (Fcurrent_bidi_paragraph_direction): Fix search for previous
9829 non-empty line. Fixes confusing cursor motion with arrow keys at
9830 the beginning of a line that starts with whitespace.
9832 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9834 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
9837 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
9839 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
9842 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9844 * xdisp.c (display_line): Record maximum and minimum buffer
9845 positions even if no glyphs were produced (e.g., by a zero-width
9846 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
9847 buffer positions that will be removed from the glyph row because
9849 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
9850 column is beyond frame width: don't subtract 1 "pixel" when
9851 computing width of the stretch.
9852 (reseat_at_next_visible_line_start): Undo the change made on
9853 2011-09-17 that saved paragraph information and restored it after
9854 the call to `reseat'. (Bug#9545)
9856 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9858 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
9859 and turn window cursor on if cleared (Bug#9415).
9861 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
9863 * search.c (boyer_moore): Take unibyte characters from pattern
9864 literally. (Bug#9458)
9866 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9868 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
9870 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
9872 Fix minor problem found by static checking.
9873 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
9874 initialized, to pacify gcc -Wuninitialized.
9876 * fileio.c: Report proper errno when syscall falls.
9877 (Finsert_file_contents): Save and restore errno,
9878 so that report_file_error outputs the correct diagnostic.
9879 (Fwrite_region) [CLASH_DETECTION]: Likewise.
9881 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9883 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
9885 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9887 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
9888 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
9890 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9892 * xdisp.c (reseat_at_next_visible_line_start): Keep information
9893 about the current paragraph and restore it after the call to reseat.
9895 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
9896 (bidi_find_paragraph_start): Search back for paragraph beginning
9897 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
9898 (bidi_move_to_visually_next): Only trigger paragraph-related
9899 computations when the last character is a newline or at EOB, not
9900 just any NEUTRAL_B. (Bug#9470)
9902 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
9903 truncated lines if point is covered by a display string. (Bug#9524)
9905 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
9907 * xselect.c: Relax test for outgoing X longs (Bug#9498).
9908 (cons_to_x_long): New function.
9909 (lisp_data_to_selection_data): Use it. Correct the test for
9910 short-versus-long data; it was negated. Break out of vector
9911 loop, for efficiency, when a long datum is discovered.
9913 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
9915 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
9917 2011-09-16 Eli Zaretskii <eliz@gnu.org>
9919 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
9920 GCC PR/17406) by declaring this function with external scope.
9922 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9924 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
9925 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
9927 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
9929 * editfns.c (Fformat): Correctly handle text properties on "%%".
9931 2011-09-15 Eli Zaretskii <eliz@gnu.org>
9933 * xterm.c (x_draw_composite_glyph_string_foreground):
9934 * w32term.c (x_draw_composite_glyph_string_foreground):
9935 * term.c (encode_terminal_code):
9936 * composite.c (composition_update_it, get_composition_id):
9937 * xdisp.c (get_next_display_element)
9938 (fill_composite_glyph_string): Add comments about special meaning
9939 of TAB characters in a composition.
9941 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9943 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
9944 This occurs when processing a multibyte format.
9945 Problem reported by Wolfgang Jenker.
9947 2011-09-15 Johan Bockgård <bojohan@gnu.org>
9949 * xdisp.c (try_cursor_movement): Only check for exact match if
9950 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
9952 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9954 Remove unused external symbols.
9955 * dispextern.h (calc_pixel_width_or_height): Remove decl.
9956 * xdisp.c (calc_pixel_width_or_height): Now static.
9957 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
9958 * indent.c (check_display_width):
9959 * w32term.c: Fix comment to match code.
9960 * xterm.c, xterm.h (x_catching_errors): Remove.
9962 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9964 * xselect.c: Use signed conversions more consistently (Bug#9498).
9965 (selection_data_to_lisp_data): Assume incoming selection data are
9966 signed integers, not unsigned. This is to be consistent with
9967 outgoing selection data, which was modified to use signed integers
9968 in as part of the fix to Bug#9196 in response to Jan D.'s comment
9969 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
9970 expects long, not unsigned long.
9972 2011-09-14 Eli Zaretskii <eliz@gnu.org>
9974 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
9975 computation of loop end. Reported by Johan Bockgård
9978 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
9980 * frame.c (Fother_visible_frames_p): Function deleted.
9982 2011-09-12 Eli Zaretskii <eliz@gnu.org>
9984 * indent.c (compute_motion): Process display vector front to back
9985 rather than the other way around. (Bug#2496)
9987 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
9989 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
9991 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
9993 * minibuf.c (Fread_from_minibuffer): Doc fix.
9995 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9997 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
9998 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
10000 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
10002 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
10003 value for non-existent files.
10005 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10007 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10008 set its "size" to -1. This will set the modtime_size field of
10009 the corresponding buffer to -1, which is what
10010 verify-visited-file-modtime expects for files that do not exist.
10013 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
10015 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10017 * lisp.h: ... from here. push_key_description is no longer
10018 defined in keyboard.c, so its declaration should not be in
10019 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10020 logically belongs with push_key_description.
10022 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10024 * buffer.h: Include <sys/types.h> instead of <time.h>.
10025 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
10026 Problem reported by Herbert J. Skuhra.
10028 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
10030 * xml.c (parse_region): Make the parsing work for
10031 non-comment-starting XML files again (bug#9144).
10033 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
10035 * image.c (gif_load): Fix calculation of bottom and right corner.
10038 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10040 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10041 redisplay in small windows.
10043 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10045 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10047 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10049 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10050 Operate on live windows only.
10052 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10054 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10056 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10058 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10059 only under bidi iteration.
10061 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10063 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10065 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10067 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10068 Without this fix, the command to link temacs failed due to an
10069 undefined symbol __builtin_isnan. This is because
10070 /usr/include/iso/math_c99.h #defines isnan(x) to
10071 __builtin_isnan(x), but the bundled gcc, which identifies itself
10072 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10074 * floatfns.c (isnan): #undef, and then #define to a clone of
10076 (Fisnan): Always define, since it's always available now.
10077 (syms_of_floatfns): Always define isnan at the Lisp level.
10079 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10081 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10083 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10085 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10086 The previous code assumed that file offsets (off_t values) fit in
10087 EMACS_INT variables, which is not true on typical 32-bit hosts.
10088 The code messed up by falsely reporting buffer overflow in cases
10089 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10090 when "big" contains more than 2**29 bytes, even though this
10091 inserts just one byte and does not overflow the buffer.
10092 (Finsert_file_contents): Store file offsets as off_t
10093 values, not as EMACS_INT values. Check for overflow when
10094 converting between EMACS_INT and off_t. When checking for
10095 buffer overflow or for overlap, take the offsets into account.
10096 Don't use EMACS_INT for small values where int suffices.
10097 When checking for overlap, fix a typo: ZV was used where
10098 ZV_BYTE was intended.
10099 (Fwrite_region): Don't assume off_t fits into 'long'.
10100 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10102 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10104 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10106 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10108 sprintf-related integer and memory overflow issues (Bug#9412).
10110 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10111 (esprintf, exprintf, evxprintf): New functions.
10112 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10113 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10114 (modify_event_symbol): Do not assume that the length of
10115 name_alist_or_stem is safe to alloca and fits in int.
10116 (Fexecute_extended_command): Likewise for function name and binding.
10117 (Frecursion_depth): Wrap around reliably on integer overflow.
10118 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10119 since some callers pass EMACS_INT values.
10120 (Fsingle_key_description): Don't crash if symbol name contains more
10121 than MAX_ALLOCA bytes.
10122 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10123 (get_minibuffer): Arg is now EMACS_INT, not int.
10124 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10125 (esprintf, exprintf, evxprintf): New decls.
10126 * window.h (command_loop_level, minibuf_level): Reflect API changes.
10128 * dbusbind.c (signature_cat): New function.
10129 (xd_signature, Fdbus_register_signal):
10130 Do not overrun buffer; instead, report string overflow.
10132 * dispnew.c (add_window_display_history): Don't overrun buffer.
10133 Truncate instead; this is OK since it's just a log.
10135 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10136 even if the time zone offset is outlandishly large.
10137 Don't mishandle offset == INT_MIN.
10139 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10140 when creating daemon; the previous buffer-overflow check was incorrect.
10142 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10143 which has the guts of the old verror function.
10145 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10146 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10148 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10149 (font_unparse_xlfd): Don't blindly alloca long strings.
10150 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10151 fits in int, when using sprintf. Use single snprintf to count
10152 length of string rather than counting it via multiple sprintfs;
10153 that's simpler and more reliable.
10154 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10155 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10156 sprintf, in case result does not fit in int.
10158 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10159 (fontset_from_font): Print it.
10161 * frame.c (tty_frame_count): Now printmax_t, not int.
10162 (make_terminal_frame, set_term_frame_name): Print it.
10163 (x_report_frame_params): In X, window IDs are unsigned long,
10164 not signed long, so print them as unsigned.
10165 (validate_x_resource_name): Check for implausibly long names,
10166 and don't assume name length fits in 'int'.
10167 (x_get_resource_string): Don't blindly alloca invocation name;
10168 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10171 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10172 (xg_check_special_colors, xg_set_geometry):
10173 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10175 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10176 Use esprintf, not sprintf, in case result does not fit in int.
10178 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10179 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10180 it as a large positive number.
10181 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10182 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10184 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10185 in case result does not fit in int.
10187 * print.c (float_to_string): Detect width overflow more reliably.
10188 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10189 buffer overrun. Don't assume list length fits in 'int'. Treat
10190 print length of 0 as 0, not as infinity; to be consistent with other
10191 uses of print length in this function. Don't overflow print length
10192 index. Don't assume hash table size fits in 'long', or that
10193 vectorlike size fits in 'unsigned long'.
10195 * process.c (make_process): Use printmax_t, not int, to format
10196 process-name gensyms.
10198 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10200 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10201 to avoid potential buffer overrun.
10203 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10204 if X resource line is longer than 512 bytes.
10206 * xfns.c (x_window): Make sprintf buffer a bit bigger
10207 to avoid potential buffer overrun.
10209 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10211 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10213 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10215 Integer overflow fixes for scrolling, etc.
10216 Without these, Emacs silently mishandles large integers sometimes.
10217 For example, "C-u 4294967297 M-x recenter" was treated as if
10218 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10220 * xdisp.c (try_window_id): Check Emacs fixnum range before
10221 converting to 'int'.
10223 * window.c (window_scroll_line_based, Frecenter):
10224 Check that an Emacs fixnum is in range before assigning it to 'int'.
10225 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10226 values converted from Emacs fixnums.
10227 (Frecenter): Don't wrap around a line count if it is out of 'int'
10228 range; instead, treat it as an extreme value.
10229 (Fset_window_configuration, compare_window_configurations):
10230 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10232 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10233 that can exceed INT_MAX. Check that EMACS_INT value is in range
10234 before assigning it to the (possibly-narrower) index.
10235 (match_limit): Don't assume that a fixnum can fit in 'int'.
10237 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10240 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10241 (Fvertical_motion): Don't wrap around LINES values that don't fit
10242 in 'int'. Instead, treat them as extreme values. This is good
10243 enough for windows, which can't have more than INT_MAX lines anyway.
10245 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10247 * Require libxml/parser.h to avoid compilation warning.
10249 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10251 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10252 since this reportedly can destroy thread storage.
10254 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10256 * syntax.c (find_defun_start): Update all cache variables if
10257 exiting early (Bug#9401).
10259 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10261 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10263 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10264 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10265 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10267 * term.c (tty_append_glyph): New function.
10268 (produce_stretch_glyph): Static function and its prototype deleted.
10270 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10273 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10275 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10276 when checking :margin (Bug#9390).
10277 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10278 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10279 so that the name doesn't mislead. All uses changed.
10281 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10283 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
10286 2011-08-27 Eli Zaretskii <eliz@gnu.org>
10288 * xdisp.c (move_it_to): Don't bail out early when reaching
10289 position beyond to_charpos, if we are scanning backwards.
10290 (move_it_vertically_backward): When DY == 0, make sure we get to
10291 the first character in the line after the newline.
10293 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10295 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10296 (ccl_driver): Do not generate an out-of-range pointer.
10297 (Fccl_execute_on_string): Remove unnecessary check for
10298 integer overflow, noted by Stefan Monnier in
10299 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10300 Remove a FIXME that didn't need fixing.
10301 Simplify the newly-introduced buffer reallocation code.
10303 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10305 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10307 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10309 Integer and memory overflow issues (Bug#9196).
10311 * doc.c (get_doc_string): Rework so that
10312 get_doc_string_buffer_size is the actual buffer size, rather than
10313 being 1 less than the actual buffer size; this makes xpalloc more
10316 * image.c (x_allocate_bitmap_record, cache_image):
10317 * xselect.c (Fx_register_dnd_atom):
10318 Simplify previous changes by using xpalloc.
10320 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10321 since either will do and ptrdiff_t is convenient with xpalloc.
10323 * charset.c (charset_table_size)
10324 (struct charset_sort_data.priority): Now ptrdiff_t.
10325 (charset_compare): Don't overflow if priorities differ greatly.
10326 (Fsort_charsets): Don't assume list length fits in int.
10327 Check for size-calculation overflow when allocating sort data.
10328 (syms_of_charset): Allocate an initial charset table that is
10329 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10331 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10333 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10334 The actual value is always <= INT_MAX, and leaving it unsigned made
10335 overflow checking harder.
10337 * dispextern.h (struct glyph_matrix.rows_allocated)
10338 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10339 with xpalloc. The values are still always <= INT_MAX.
10341 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10343 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10344 (SAFE_NALLOCA): New macro.
10346 * region-cache.c (struct boundary.pos, find_cache_boundary)
10347 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10348 (set_cache_region, invalidate_region_cache)
10349 (revalidate_region_cache, know_region_cache, region_cache_forward)
10350 (region_cache_backward, pp_cache):
10351 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10352 so that ptrdiff_t * can be passed to xpalloc.
10353 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
10354 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
10355 (pp_cache): Don't assume cache_len fits in int.
10356 * region-cache.h: Adjust extern decls to match.
10358 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
10359 EMACS_INT, since either will do, for xpalloc.
10361 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
10362 (xnmalloc, xnrealloc, xpalloc): New functions.
10364 * bidi.c (bidi_shelve_header_size): New constant.
10365 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
10366 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
10368 * bidi.c (bidi_cache_shrink):
10369 * buffer.c (overlays_at, overlays_in, record_overlay_string)
10371 Don't update size of array until after memory allocation succeeds,
10372 because xmalloc/xrealloc may not return.
10373 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10374 now that we have proper integer overflow checking.

10376 calculating size of overlay_str_buf.
10378 * callproc.c (Fcall_process): Check for size overflow when
10379 calculating size of args2.
10380 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
10381 Normally we prefer signed values, but sticking with ptrdiff_t would
10382 require adding more-complicated checks.
10384 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10385 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
10386 Redo buffer-overflow calculations to avoid integer overflow.

10425 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10427 * emacs.c (main): Do not reallocate argv, since there is a null at
10428 the end that can be overwritten, and this way there's no need to
10429 worry about size-calculation overflow.
10430 (sort_args): Check for size-calculation overflow.
10432 * eval.c (init_eval_once, grow_specpdl): Don't update size until

10438 Check for integer overflow.
10439 (x_set_alpha): Do not assume XINT fits in int.
10441 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10442 This is for the members text_lines, text_cols, total_lines, total_cols,
10443 where the system imposes an 'int' limit.

10452 Check for size-calculation overflow.
10453 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10454 do, as we prefer signed integers.

10461 * gtkutil.h: Change prototypes to match the above.
10463 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

10558 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
10559 (X_LONG_MIN): New macros.
10560 Use them to make the following changes clearer.
10561 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
10562 This change doesn't affect the value now, but it may help remind
10563 future maintainers not to raise the value too much later.
10564 (SELECTION_QUANTUM): Remove, replacing with ...
10565 (selection_quantum): ... new function, which avoids overflow.
10567 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10568 assumption that selection length fits in 'int'.

10585 Don't store size until memory allocation succeeds.
10586 (x_get_window_property): Plug memory leak on memory exhaustion.
10587 Don't double-block input; malloc is safe here. Don't assume 2**34
10588 - 4 fits in unsigned long. Add an xassert to check
10589 XGetWindowProperty overflow. Be more careful about overflow
10590 calculations, and distinguish size from memory overflow better.
10591 (receive_incremental_selection): When tracing, don't assume
10592 unsigned int is less than INT_MAX.
10593 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

10596 in the range -65535 through -1 fit in an X unsigned short.
10597 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10598 result parameters unless successful. Rely on cons_to_unsigned
10599 to report problems with elements; the old code wasn't right anyway.
10600 (x_check_property_data): Check for int overflow; we cannot use
10601 a wider type due to X limits.

10634 * lisp.h (hash_lookup, hash_put):
10635 * minibuf.c (Ftest_completion):
10636 Use ptrdiff_t for hash table indexes, not int (which is too
10637 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
10638 32-bit --with-wide-int hosts).
10640 * charset.c (Fdefine_charset_internal): Check for integer overflow.
10641 Add a FIXME comment about memory leaks.

10649 with outlandish widths.
10650 * character.h (sanitize_tab_width): Rename from sanitize_width,
10651 now that we have two such functions. All uses changed.

10670 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
10671 (x_send_scroll_bar_event): Likewise. Check that the size does not
10672 exceed limits imposed by XClientMessageEvent, as well as the usual
10673 ptrdiff_t and size_t limits.
10675 * keyboard.c: Overflow, signedness and related fixes.
10676 (make_lispy_movement): Use same integer type in forward decl
10677 that is used in the definition.

10679 Change bufsize argument back to int, undoing my 2011-03-30 change.
10680 We prefer signed types, and int is wide enough here.
10681 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
10682 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
10683 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
10684 length, not size_t. Use ptrdiff_t for index, not int.
10685 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
10686 possibility of integer overflow.

10714 Prefer int to unsigned where either will do.
10715 (tiff_handler): New function, combining the cores of the
10716 old tiff_error_handler and tiff_warning_handler.
10717 This function is rewritten to use vsnprintf and thereby avoid
10718 stack buffer overflows. It uses only the features of vsnprintf
10719 that are common to both POSIX and native Microsoft.
10720 (tiff_error_handler, tiff_warning_handler): Use it.
10721 (tiff_load, gif_load, imagemagick_load_image):
10722 Don't assume :index value fits in 'int'.

10724 (imagemagick_load_image): Check that crop parameters fit into
10725 the integer types that MagickCropImage accepts. Don't assume
10726 Vimagemagick_render_type has a nonnegative value. Don't assume
10727 size_t fits in 'long'.
10728 (gs_load): Use printmax_t to print the widest integers possible.

10741 handle_single_display_spec, not just 1 or zero.
10742 (handle_single_display_spec): If the display spec is of the form
10743 `(space ...)', and specifies display in the text area, return 2
10745 (try_cursor_movement): Check for the need to scroll more
10746 accurately, and prefer exact match for point under bidi.
10747 Don't advance `row' beyond the last row of the window.

10765 buffers, return left-to-right.
10766 (set_cursor_from_row): Consider candidate row a win if its glyph
10767 represents a newline and point is on that newline. Fixes cursor
10768 positioning on the newline at EOL of R2L text within L2R
10769 paragraph, and vice versa.
10770 (try_cursor_movement): Check continued rows, in addition to
10771 continuation rows. Fixes unwarranted scroll when point enters a
10772 continued line of R2L text within an L2R paragraph, or vice versa.
10773 (cursor_row_p): Consider the case of point being equal to
10774 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
10775 from the end of a short line to the beginning of a continued line
10776 of R2L text within L2R paragraph.
10777 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

10800 * xdisp.c (redisplay_window): When computing centering_position,
10801 account for the height of the header line. (Bug#8874)
10803 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
10804 instead of CHAR_TO_BYTE. Fixes a crash when a completion
10805 candidate is selected by the mouse, and that candidate has a
10806 composed character under the mouse.
10808 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
10809 coordinates reported by pos-visible-in-window-p for a composed
10810 character in column zero.
10812 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
10814 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.

10820 composed buffer positions.
10822 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
10824 * image.c (gif_load): Don't assume that each subimage has the same
10825 dimensions as the base image. Handle disposal method that is
10826 "undefined" by the gif spec (Bug#9335).
10828 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
10830 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

10836 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
10837 from an Org mode buffer to a Speedbar frame.
10839 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
10840 a composition, take its buffer position from IT->cmp_it.charpos.
10841 Fixes cursor positioning at the beginning of a line that begins
10842 with a composed character.
10844 2011-08-18 Eli Zaretskii <eliz@gnu.org>
10846 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
10847 character bidirectional type, use STRONG_L instead. Fixes crashes
10848 in a buffer produced by `describe-categories'.
10850 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
10851 members before the level stack, so they would be saved and
10852 restored when copying iterator state. Fixes incorrect reordering
10853 around TABs covered by display properties.
10855 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
10857 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

10862 (internal_condition_case_2, internal_condition_case_n):
10863 Remove unnecessary aborts (Bug#9081).
10865 2011-08-17 Eli Zaretskii <eliz@gnu.org>
10867 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
10868 has no `load' handler, try opening the file locally. (Bug#9311)
10870 2011-08-16 Ken Brown <kbrown@cornell.edu>
10872 * gmalloc.c: Expand comment.
10874 2011-08-16 Eli Zaretskii <eliz@gnu.org>

10888 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
10890 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
10891 in the static heap.
10892 [CYGWIN] (special_realloc): New function.
10893 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
10894 requests to realloc storage in the static heap.

10909 * chartab.c: Improve commentary for the uniprop_table API.
10911 * bidi.c (bidi_paragraph_init): Support zero value of
10912 bidi_ignore_explicit_marks_for_paragraph_level.
10913 (bidi_initialize): Use uniprop_table instead of including
10914 biditype.h and bidimirror.h.

10923 after the pid of the process is set to -1 (Bug#8162).
10925 2011-08-14 Eli Zaretskii <eliz@gnu.org>
10927 * xdisp.c (move_it_in_display_line_to): Don't invoke
10928 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
10929 ppos_it. Fixes vertical cursor motion when line beginning is
10930 covered by an image. (Bug#9296)
10932 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
10934 * nsterm.h (ns_run_ascript): Declare.
10935 (NSAPP_DATA2_RUNASSCRIPT): Define.
10937 * nsfns.m (as_script, as_result, as_status): New static variables.
10938 (ns_run_ascript): New function.
10939 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
10940 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
10941 the event loop. Get status from as_status (Bug#7276).
10943 * nsterm.m (sendEvent): If event is NSApplicationDefined and
10944 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
10945 the event loop (Bug#7276).
10947 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
10949 * gnutls.c (QCgnutls_bootprop_priority)

10951 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
10952 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
10953 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
10954 (QCgnutls_bootprop_verify_hostname_error)

10970 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
10971 (Fnetwork_interface_list): Allocate in increments of bytes instead
10972 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
10973 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
10975 (struct ifflag_def): notrailers is smart on OSX.
10976 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
10977 Get hardware address with getifaddrs if available.
10979 2011-08-12 Eli Zaretskii <eliz@gnu.org>
10981 * xdisp.c (iterate_out_of_display_property): xassert that
10982 IT->position is set to within IT->object's boundaries. Break from
10983 the loop as soon as EOB is reached; avoids infloops in redisplay
10984 when IT->position is set up wrongly due to some bug.
10985 Set IT->current to match the bidi iterator unconditionally.
10986 (push_display_prop): Allow GET_FROM_STRING as IT->method on
10987 entry. Force push_it to save on the stack the current
10988 buffer/string position, to be restored by pop_it. Fix flags in
10989 the iterator structure wrt the object coming from a display
10990 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
10991 properties. (Bug#9284)
10993 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
10995 * fontset.c (fontset_get_font_group): Add proper type checks.

11008 no-display-properties-and-no-overlays under bidi display.
11009 Set disp_pos in the bidi iterator to avoid searches for display
11010 properties and overlays.
11012 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
11014 * editfns.c (Fset_time_zone_rule): Document relationship with the

11023 restore_point_unwind (Bug#5984).
11025 2011-08-07 Juri Linkov <juri@jurta.org>
11027 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
11028 to show the arg `TIME' instead of `TIMEVAL'.
11030 2011-08-06 Eli Zaretskii <eliz@gnu.org>
11032 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
11033 display property strides EOL and includes a newline, as in
11034 longlines-mode. (Bug#9254)
11035 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
11036 word-wrap under bidirectional display. (Bug#9224)
11038 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
11039 is non-zero, even if the data buffer is NULL. Fixes a crash in
11040 vertical-motion with longlines-mode. (Bug#9254)
11042 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11044 * bidi.c <bidi_cache_total_alloc>: Now static.
11045 (bidi_initialize): Initialize bidi_cache_total_alloc.
11047 * xdisp.c (display_line): Release buffer allocated for shelved bidi
11050 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
11051 amount allocated this far in `bidi_cache_total_alloc'.
11052 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
11053 non-zero, only free the data buffer without restoring the cache
11054 contents. All callers changed.
11056 * dispextern.h (bidi_unshelve_cache): Update prototype.
11058 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
11059 (move_it_in_display_line, move_it_to)
11060 (move_it_vertically_backward, move_it_by_lines): Replace the call
11061 to xfree to an equivalent call to bidi_unshelve_cache.
11062 (move_it_in_display_line_to): Fix logic of returning
11063 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
11065 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11067 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
11068 came from a string character with a `cursor' property. (Bug#9229)
11070 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11072 * Makefile.in (LIB_PTHREAD): New variable.
11073 (LIBES): Add LIB_PTHREAD (Bug#9216).
11075 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
11076 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
11078 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
11080 * regex.c (re_iswctype): Remove some redundant boolean conversions.
11082 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11084 * xterm.c (x_find_topmost_parent): New function.
11085 (x_set_frame_alpha): Find topmost parent window with
11086 x_find_topmost_parent and set the property there also (bug#9181).
11087 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
11089 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>

11100 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
11101 so that it is not optimized away.
11103 * xdisp.c (compute_display_string_pos): Remove unused local.
11105 2011-08-02 Eli Zaretskii <eliz@gnu.org>
11107 Fix slow cursor motion and scrolling in large buffers with
11108 selective display, like Org Mode buffers. (Bug#9218)
11110 * dispextern.h (struct bidi_it): New member disp_prop_p.
11112 * xdisp.c: Remove one-slot cache of display string positions.
11113 (compute_display_string_pos): Accept an additional argument

11115 for a display string or property. If found, set DISP_PROP_P
11118 * bidi.c (bidi_fetch_char): Accept an additional argument
11119 DISP_PROP_P, and pass it to compute_display_string_pos.
11120 Only handle text covered by a display string if DISP_PROP_P is returned
11121 non-zero. All callers of bidi_fetch_char changed.
11123 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
11125 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
11127 2010-12-03 Don March <don@ohspite.net>
11129 * keymap.c (Fdefine_key): Fix non-prefix key error message when
11130 last character M-[char] is translated to ESC [char] (bug#7541).
11132 2011-08-02 Kenichi Handa <handa@m17n.org>
11134 * lisp.h (uniprop_table): Extern it.
11136 * chartab.c (uniprop_table): Make it non-static.
11138 2011-08-01 Eli Zaretskii <eliz@gnu.org>
11140 * xdisp.c (forward_to_next_line_start): Accept additional argument
11141 BIDI_IT_PREV, and store into it the state of the bidi iterator had
11143 (reseat_at_next_visible_line_start): Use the bidi iterator state
11144 returned by forward_to_next_line_start to restore the state of
11145 it->bidi_it after backing up to previous newline. (Bug#9212)
11147 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
11149 * regex.c (re_comp): Protoize.
11150 (re_exec): Fix return type.
11151 (regexec): Fix type of `ret'. (Bug#9203)
11153 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11155 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
11156 This is needed if max-image-size is a floating-point number.
11158 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11160 * print.c (print_object): Print empty symbol as ##.

11166 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
11167 setting frame foreground color (Bug#9175).
11168 (x_set_background_color): Likewise.

11171 contents (Bug#9176).
11172 (EmacsTooltip -init): Remove bezels and add shadows to
11175 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
11176 or scroll bar (Bug#8470).
11178 * nsfont.m (nsfont_open): Remove assignment to voffset and
11179 unnecessary vars hshink, expand, hd, full_height, min_height.

11182 * nsterm.h (nsfont_info): Remove voffset field.
11184 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11186 Implement strike-through and overline on NextStep (Bug#8863).
11188 * nsfont.m (nsfont_open): Use underline position provided by font,
11189 instead of hard-coded value of 2.
11190 (nsfont_draw): Call ns_draw_text_decoration instead.

11200 2011-07-28 Eli Zaretskii <eliz@gnu.org>
11202 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
11205 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11207 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11208 Without this fix, if a signal arrives just after memory fills up,
11209 'malloc' might be invoked reentrantly.
11211 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11212 In other words, assume that every image size is allowed, on non-X
11213 hosts. This assumption is probably wrong, but it lets Emacs compile.
11215 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11217 * regex.c (re_iswctype): Convert return values to boolean.
11219 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
11221 * xdisp.c (compute_display_string_pos): Don't use cached display
11222 string position if the buffer had its restriction changed.
11225 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11227 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11229 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11231 Integer signedness and overflow and related fixes. (Bug#9079)
11233 * bidi.c: Integer size and overflow fixes.
11234 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
11235 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
11236 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11237 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11238 (bidi_find_other_level_edge):
11239 Use ptrdiff_t instead of EMACS_INT where either will do.
11240 This works better on 32-bit hosts configured --with-wide-int.
11241 (bidi_cache_ensure_space): Check for size-calculation overflow.
11242 Use % rather than repeated addition, for better worst-case speed.
11243 Don't set bidi_cache_size until after xrealloc returns, because it
11245 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11246 (bidi_cache_ensure_space): Also check that the bidi cache size
11247 does not exceed that of the largest Lisp string or buffer. See Eli
11248 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11250 * alloc.c (__malloc_size_t): Remove.
11251 All uses replaced by size_t. See Andreas Schwab's note
11252 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11254 * image.c: Improve checking for integer overflow.
11255 (check_image_size): Assume that f is nonnull, since
11256 it is always nonnull in practice. This is one less thing to
11257 worry about when checking for integer overflow later.
11258 (x_check_image_size): New function, which checks for integer
11259 overflow issues inside X.
11260 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11261 This removes the need for a memory_full check.
11262 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11263 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11264 (xbm_read_bitmap_data): Change locals back to 'int', since
11265 their values must fit in 'int'.
11266 (xpm_load_image, png_load, tiff_load):
11267 Invoke x_create_x_image_and_pixmap earlier,
11268 to avoid much needless work if the image is too large.
11269 (tiff_load): Treat overly large images as if
11270 x_create_x_image_and_pixmap failed, not as malloc failures.
11271 (gs_load): Use x_check_image_size.
11273 * gtkutil.c: Omit integer casts.
11274 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11275 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11277 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11279 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11280 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11281 would wrongly return t on a 64-bit host.
11283 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11284 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11285 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11286 and therefore cause GCC to emit a bogus diagnostic in some cases.
11288 * image.c: Integer signedness and overflow and related fixes.
11289 This is not an exhaustive set of fixes, but it's time to
11290 record what I've got.
11291 (lookup_pixel_color, check_image_size): Remove redundant decls.
11292 (check_image_size): Don't assume that arbitrary EMACS_INT values
11293 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11294 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11295 (tiff_load, imagemagick_load_image):
11296 Check for overflow in size calculations.
11297 (x_create_x_image_and_pixmap): Remove unnecessary test for
11298 xmalloc returning NULL; that can't happen.
11299 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11300 (xpm_color_bucket): Use better integer hashing function.
11301 (xpm_cache_color): Don't possibly over-allocate memory.
11302 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11303 (gif_memory_source):
11304 Use ptrdiff_t, not int or size_t, to record sizes.
11305 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11306 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11307 either works, as we prefer signed integers.
11308 (tiff_read_from_memory, tiff_write_from_memory):
11309 Return tsize_t, not size_t, since that's what the TIFF API wants.
11310 (tiff_read_from_memory): Don't fail simply because the read would
11311 go past EOF; instead, return a short read.
11312 (tiff_load): Omit no-longer-needed casts.
11313 (Fimagemagick_types): Don't assume size fits into 'int'.
11315 Improve hashing quality when configured --with-wide-int.
11316 * fns.c (hash_string): New function, taken from sxhash_string.
11317 Do not discard information about ASCII character case; this
11318 discarding is no longer needed.
11319 (sxhash-string): Use it. Change sig to match it. Caller changed.
11320 * lisp.h: Declare it.
11321 * lread.c (hash_string): Remove, since we now use fns.c's version.
11322 The fns.c version returns a wider integer if --with-wide-int is
11323 specified, so this should help the quality of the hashing a bit.
11325 * emacs.c: Integer overflow minor fix.
11326 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11327 Define only if GNU_LINUX.
11328 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11330 * dispnew.c: Integer signedness and overflow fixes.
11331 Remove unnecessary forward decls, that were a maintenance hassle.
11332 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11334 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11335 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11336 (prepare_desired_row, line_draw_cost):
11337 Use int, not unsigned, where either works.
11338 (save_current_matrix, restore_current_matrix):
11339 Use ptrdiff_t, not size_t, where either works.
11340 (init_display): Check for overflow more accurately, and without
11341 relying on undefined behavior.
11343 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11344 Remove, replacing with the new symbols in lisp.h. All uses changed.
11345 * fileio.c (make_temp_name):
11346 * filelock.c (lock_file_1, lock_file):
11347 * xdisp.c (message_dolog):
11348 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11349 Use pMd etc. instead.
11350 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11351 replacing the pWIDE etc. symbols removed from editfns.c.
11353 * keyboard.h (num_input_events): Now uintmax_t.
11354 This is (very slightly) less likely to mess up due to wraparound.
11357 * buffer.c: Integer signedness fixes.
11358 (alloc_buffer_text, enlarge_buffer_text):
11359 Use ptrdiff_t rather than size_t when either will do, as we prefer
11362 * alloc.c: Integer signedness and overflow fixes.
11363 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11364 (__malloc_size_t): Default to size_t, not to int.
11365 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11366 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11367 Prefer ptrdiff_t to size_t when either would do, as we prefer
11369 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11370 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11371 Now const. Initialize with values that are in range even if char
11373 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11374 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11375 These functions do the right thing with sizes > 2**32.
11376 (check_depth): Now ptrdiff_t, not int.
11377 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11378 Adjust to new way of storing sizes. Check for size overflow bugs
11380 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11381 slightly wrong anyway, as it missed one instance of
11382 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11383 (refill_memory_reserve): Omit needless cast to size_t.
11384 (mark_object_loop_halt): Mark as externally visible.
11386 * xselect.c: Integer signedness and overflow fixes.
11387 (Fx_register_dnd_atom, x_handle_dnd_message):
11388 Use ptrdiff_t, not size_t, since we prefer signed.
11389 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11390 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11391 x_dnd_atoms_size and x_dnd_atoms_length.
11393 * doprnt.c: Prefer signed to unsigned when either works.
11395 * doprnt.c (doprnt):
11397 * xdisp.c (vmessage):
11398 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11399 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11400 prefer signed arithmetic to avoid comparison confusion.
11401 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11402 but is a bit tricky.
11404 Assume freestanding C89 headers, string.h, stdlib.h.
11405 * data.c, doprnt.c, floatfns.c, print.c:
11406 Include float.h unconditionally.
11407 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11408 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11409 * regex.c: Likewise for stddef.h, string.h.
11410 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11411 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11412 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11413 (STDC_HEADERS): Remove obsolete defines.
11414 * sysdep.c: Include limits.h unconditionally.
11416 Assume support for memcmp, memcpy, memmove, memset.
11417 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11418 * regex.c (memcmp, memcpy):
11419 Remove; we assume C89 now.
11421 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11422 (__malloc_safe_bcopy): Remove; no longer needed.
11424 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11425 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11426 well either way, and we prefer signed to unsigned.
11428 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11430 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11431 closes the connection while we're reading (bug#9182).
11433 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11435 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11436 are specified (Bug#9168).
11438 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11440 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11441 Found by GCC static checking and --with-wide-int on a 32-bit host.
11443 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11445 * xdisp.c (compute_display_string_pos): Fix logic of caching
11446 previous display string position. Initialize cached_prev_pos to
11447 -1. Fixes slow-down at the beginning of a buffer.
11449 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11451 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11452 for attrs[LFACE_FONTSET_INDEX].
11454 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11456 * xml.c (parse_region): Remove unused local
11457 that was recently introduced.
11459 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11461 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11462 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11464 * xdisp.c (move_it_in_display_line_to): Record the best matching
11465 position for TO_CHARPOS while scanning the line, and restore it on
11466 exit if none of the characters scanned was an exact match.
11467 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11468 when exact match is impossible due to invisible text, and the
11469 lines are truncated.
11471 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11473 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11476 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11478 Fix a significant slow-down of cursor motion with C-n, C-p,
11479 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11480 auto-repeat under bidi redisplay in fontified buffers.
11481 * xdisp.c (compute_stop_pos_backwards): New function.
11482 (next_element_from_buffer): Call compute_stop_pos_backwards to
11483 find a suitable prev_stop when we find ourselves before
11485 (reseat): Don't look for prev_stop, as that could mean a very long
11487 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11488 <cached_disp_overlay_modiff>: Cache for last found display string
11490 (compute_display_string_pos): Return the cached position if asked
11491 about the same buffer in the same area of character positions, and
11492 the buffer wasn't changed since the time the display string
11493 position was cached.
11495 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11497 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11498 is an integer, which is important for empty lines. (Bug#9149)
11500 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11502 * frame.c (Fmodify_frame_parameters): In tty case, update the
11503 default face if necessary (Bug#4238).
11505 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11507 * editfns.c (Fstring_to_char): No need to explain what a character
11508 is in the docstring (Bug#6576).
11510 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11512 * xml.c (parse_region): Make sure we always return a tree.
11514 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11516 * xml.c (parse_region): If a document contains only comments,
11519 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11521 * xml.c (make_dom): Return comments, too.
11523 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11526 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11527 and the surrounding thread.
11528 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11529 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11530 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11532 * s/openbsd.h (BROKEN_SIGIO): Define.
11533 * unexelf.c (unexec) [__OpenBSD__]:
11534 Don't update the .mdebug section of the Alpha COFF symbol table.
11536 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11538 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11541 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11543 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11544 This fixes some race conditions on the permissions of any newly
11547 * alloc.c (valid_pointer_p): Use pipe, not open.
11548 This fixes some permissions issues when debugging.
11550 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11551 If fchown fails to set both uid and gid, try to set just gid,
11552 as that is sometimes allowed. Adjust the file's mode to eliminate
11553 setuid or setgid bits that are inappropriate if fchown fails.
11555 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11557 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11558 to compare Lisp_Objects.
11559 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11560 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11561 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11563 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11565 * lread.c (read_integer): Unread even EOF character.
11566 (read1): Likewise. Properly record start position of symbol.
11568 * lread.c (read1): Read `#:' as empty uninterned symbol if no
11569 symbol character follows.
11571 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11573 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11574 This works around a problem with the previous change to Fcopy_file.
11575 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11576 and without this change, GCC might complain about discarding
11577 fchown's return value.
11579 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11581 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11583 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11585 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11587 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11589 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11590 it's used from the C level.
11592 * process.c: Use the same condition for POLL_FOR_INPUT in both
11593 keyboard.c and process.c (bug#1858).
11595 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11597 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11598 (Fgnutls_boot): Use it.
11600 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11602 * doc.c (Fsubstitute_command_keys): Revert last change.
11604 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11606 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11607 quotes the next character, and doesn't affect other longer
11608 sequences (bug#8935).
11610 * lread.c (syms_of_lread): Clarify that is isn't only
11611 `eval-buffer' and `eval-defun' that's affected by
11612 `lexical-binding' (bug#8460).
11614 2011-07-15 Eli Zaretskii <eliz@gnu.org>
11616 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11617 bidi redisplay when a line includes both an image and is truncated.
11619 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11621 Fix minor problems found by static checking.
11622 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11623 (elsz): Now a signed constant, not a size_t var. We prefer signed
11624 types to unsigned, to avoid integer comparison confusion. Without
11625 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
11626 "cannot optimize loop, the loop counter may overflow", a symptom
11628 * indent.c (Fvertical_motion): Mark locals as initialized.
11629 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
11631 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
11633 * search.c (Fre_search_backward): Mention `case-fold-search' in
11634 all the re_search_* functions (bug#8138).
11636 * keyboard.c (Fopen_dribble_file): Document when the file is
11639 2011-07-14 Eli Zaretskii <eliz@gnu.org>
11641 * bidi.c (bidi_dump_cached_states): Fix format of displaying
11644 Support bidi reordering of display and overlay strings.
11645 * xdisp.c (compute_display_string_pos)
11646 (compute_display_string_end): Accept additional argument STRING.
11647 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
11648 (reseat_to_string): Initialize bidi_it->string.s and
11649 bidi_it->string.schars.
11650 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
11651 NULL (avoids a crash in bidi_paragraph_init).
11652 Initialize itb.string.lstring.
11653 (init_iterator): Call bidi_init_it only of a valid
11654 buffer position was specified. Initialize paragraph_embedding to
11656 (reseat_to_string): Initialize the bidi iterator.
11657 (display_string): If we need to ignore text properties of
11658 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
11659 original value of -1 will not work with bidi.)
11660 (compute_display_string_pos): First arg is now struct
11661 `text_pos *'; all callers changed. Support display properties on
11663 (compute_display_string_end): Support display properties on Lisp
11665 (init_iterator, reseat_1, reseat_to_string): Initialize the
11666 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
11667 when iterating on a string not from display properties).
11668 (compute_display_string_pos, compute_display_string_end):
11669 Fix calculation of the object to scan. Fixes an error when using
11671 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
11672 base_level_stop; instead, set base_level_stop to BEGV.
11673 Fixes crashes in vertical-motion.
11674 (next_element_from_buffer): Improve commentary for when
11675 the iterator is before prev_stop.
11676 (init_iterator): Initialize bidi_p from the default value of
11677 bidi-display-reordering, not from buffer-local value. Use the
11678 buffer-local value only if initializing for buffer iteration.
11679 (handle_invisible_prop): Support invisible properties on strings
11680 that are being bidi-reordered.
11681 (set_iterator_to_next): Support bidi reordering of C strings and
11683 (next_element_from_string): Support bidi reordering of Lisp
11685 (handle_stop_backwards): Support Lisp strings as well.
11686 (display_string): Support display of R2L glyph rows.
11687 Use IT_STRING_CHARPOS when displaying from a Lisp string.
11688 (init_iterator): Don't initialize it->bidi_p for strings
11690 (reseat_to_string): Initialize it->bidi_p for strings here.
11691 (next_element_from_string, next_element_from_c_string)
11692 (next_element_from_buffer): Add xassert's for correspondence
11693 between IT's object being iterated and it->bidi_it.string
11695 (face_before_or_after_it_pos): Support bidi iteration.
11696 (next_element_from_c_string): Handle the case of the first string
11697 character that is not the first one in the visual order.
11698 (get_visually_first_element): New function, refactored from common
11699 parts of next_element_from_buffer, next_element_from_string, and
11700 next_element_from_c_string.
11701 (tool_bar_lines_needed, redisplay_tool_bar)
11702 (display_menu_bar): Force left-to-right direction. Add a FIXME
11703 comment for making that be controlled by a user option.
11704 (push_it, pop_it): Save and restore the state of the
11705 bidi iterator. Save and restore the bidi_p flag.
11706 (pop_it): Iterate out of display property for string iteration as
11708 (iterate_out_of_display_property): Support iteration over strings.
11709 (handle_single_display_spec): Set up it->bidi_it for iteration
11710 over a display string, and call bidi_init_it.
11711 (handle_single_display_spec, next_overlay_string)
11712 (get_overlay_strings_1, push_display_prop): Set up the bidi

12151 * alloc.c (mark_buffer):
12152 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
12153 (clone_per_buffer_values): Don't assume that
12154 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
12155 This isn't true in general, and it's particularly not true
12156 if Emacs is configured with --with-wide-int.
12157 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
12158 New macros, used in the buffer.c change.

12165 (store_tool_bar_style_changed): New functions.
12166 (store_monospaced_changed): Add comment. Call dpyinfo_valid.
12167 (struct xsettings): Move font inside HAVE_XFT.
12168 (GSETTINGS_TOOL_BAR_STYLE, GSETTINGS_FONT_NAME): New defines.
12169 (GSETTINGS_MONO_FONT): Rename from SYSTEM_MONO_FONT.
12170 Move inside HAVE_XFT.
12171 (something_changed_gsettingsCB): Rename from something_changedCB.
12172 Check for changes in GSETTINGS_TOOL_BAR_STYLE and GSETTINGS_FONT_NAME
12174 (GCONF_TOOL_BAR_STYLE, GCONF_FONT_NAME): New defines.

12178 (parse_settings): Move check for font inside HAVE_XFT.
12179 (read_settings, apply_xft_settings): Add comment.
12180 (read_and_apply_settings): Add comment. Call map_tool_bar_style and
12181 store_tool_bar_style_changed. Move check for font inside HAVE_XFT and
12182 call store_font_name_changed.
12183 (xft_settings_event): Add comment.
12184 (init_gsettings): Add comment. Get values for GSETTINGS_TOOL_BAR_STYLE
12185 and GSETTINGS_FONT_NAME. Move check for fonts within HAVE_XFT.

12192 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
12194 Random fixes. E.g., (random) never returned negative values.
12195 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
12196 subseconds part to the entropy, as that's a bit more random.
12197 Prefer signed to unsigned, since the signedness doesn't matter and
12198 in general we prefer signed. When given a limit, use a
12199 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12200 latter isn't right if USE_2_TAGS_FOR_INTS.
12201 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12202 not 0..VALMASK. Don't discard "excess" bits that random () returns.
12204 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
12206 * textprop.c (text_property_stickiness):
12207 Obey Vtext_property_default_nonsticky.
12208 (syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.
12209 * w32fns.c (syms_of_w32fns):

12212 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
12214 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
12215 This is more efficient than Ffile_directory_p and avoids a minor race.
12217 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
12219 * buffer.c (Foverlay_put): Say what the return value is
12222 * fileio.c (barf_or_query_if_file_exists): Check first if the file
12223 is a directory before asking whether to use the file name
12225 (barf_or_query_if_file_exists): Make the "File is a directory"
12226 error be more correct.
12228 * fns.c (Frequire): Remove the mention of the .gz files, since
12229 that's installation-specific, but keep the mention of
12230 `get-load-suffixes'.
12232 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
12234 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

12239 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
12240 (syms_of_gnutls): Remove duplicate DEFSYM for
12241 Qgnutls_bootprop_verify_hostname_error, an error for
12242 Qgnutls_bootprop_verify_error (which is no longer used).
12244 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
12245 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
12246 Also (re)move comments that are misplaced or no longer relevant.
12248 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12250 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).
12252 2011-07-03 Chong Yidong <cyd@stupidchicken.com>
12254 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
12255 and background color parameters if they have been changed.

12275 * lread.c (syms_of_lread): Mention single symbols defined by
12276 `defvar' or `defconst' (bug#7154).
12278 * fns.c (Frequire): Mention .el.gz files (bug#7314).
12279 (Frequire): Mention get-load-suffixes.

12309 (syms_of_keymap): Defsubr make-composed-keymap.
12310 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

12347 * eval.c (struct backtrace): Simplify and port the data structure.
12348 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12349 signed bit field, as this assumption is not portable and it makes
12350 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12351 "char debug_on_exit : 1" as this is not portable either; instead,
12352 use the portable "unsigned int debug_on_exit : 1". Remove unused
12353 member evalargs. Remove obsolete comments about cc bombing out.
12355 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
12357 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

12587 (debug_method_add): Use va_list and vsprintf rather than relying
12588 on undefined behavior with wrong number of arguments.
12589 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12590 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12591 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12592 since we're not interested in debugging glyphs with old libraries.
12593 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12594 GCC 4.6.0's static checking.
12596 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12598 Integer overflow and signedness fixes (Bug#8873).
12599 A few related buffer overrun fixes, too.

12607 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
12608 (x_create_bitmap_from_xpm_data):
12609 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
12610 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
12612 * xfaces.c (load_pixmap):
12613 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
12614 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
12615 (.bitmaps_last, struct x_output.icon_bitmap):
12616 Use ptrdiff_t, not int, for bitmap indexes.
12617 (x_allocate_bitmap_record): Check for size overflow.
12618 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
12620 Use ptrdiff_t, not int, for overlay counts.
12621 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
12622 * editfns.c (overlays_around, get_pos_property):
12623 * textprop.c (get_char_property_and_overlay):
12624 * xdisp.c (next_overlay_change, note_mouse_highlight):
12625 * xfaces.c (face_at_buffer_position):
12626 * buffer.c (OVERLAY_COUNT_MAX): New macro.
12627 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
12628 (Fnext_overlay_change, Fprevious_overlay_change)
12629 (mouse_face_overlay_overlaps, Foverlays_in):
12630 Use ptrdiff_t, not int, for sizes.
12631 (overlays_at, overlays_in): Check for size-calculation overflow.
12633 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
12635 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
12636 (x_session_initialize): Do not assume string length fits in int.
12638 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
12639 This is unlikely, but can occur if DPI is outlandish.
12641 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
12642 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
12644 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
12645 * xrdb.c (magic_file_p, search_magic_path):
12646 Omit last arg SUFFIX; it was always 0. All callers changed.
12647 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
12649 * xfont.c (xfont_match): Avoid need for strlen.
12651 * xfns.c: Don't assume strlen fits in int.
12652 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
12654 * xdisp.c (message_log_check_duplicate): Return intmax_t,
12655 not unsigned long, as we prefer signed integers. All callers changed.
12656 Detect integer overflow in repeat count.
12657 (message_dolog): Don't assume print length fits in 39 bytes.
12658 (display_mode_element): Don't assume strlen fits in int.
12660 * termcap.c: Don't assume sizes fit in int and never overflow.
12661 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
12662 (gobble_line): Check for size-calculation overflow.
12664 * minibuf.c (Fread_buffer):
12665 * lread.c (intern, intern_c_string):
12666 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
12667 Don't assume string length fits in int.
12669 * keyboard.c (parse_tool_bar_item):
12670 * gtkutil.c (style_changed_cb): Avoid need for strlen.
12672 * font.c: Don't assume string length fits in int.
12673 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
12674 Use ptrdiff_t, not int.
12675 (font_intern_prop): Don't assume string length fits in int.
12676 Don't assume integer property fits in fixnum.
12677 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
12679 * filelock.c: Fix some buffer overrun and integer overflow issues.
12680 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
12681 Reformulate so as not to need the command string.
12682 Invoke gzip -cd rather than gunzip, as it's more portable.
12683 (lock_info_type, lock_file_1, lock_file):
12684 Don't assume pid_t and time_t fit in unsigned long.
12685 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
12686 (current_lock_owner): Prefer signed type for sizes.
12687 Use memcpy, not strncpy, where memcpy is what is really wanted.
12688 Don't assume (via atoi) that time_t and pid_t fit in int.
12689 Check for time_t and/or pid_t out of range, e.g., via a network share.
12690 Don't alloca where an auto var works fine.
12692 * fileio.c: Fix some integer overflow issues.
12693 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
12694 Don't assume string length fits in int.
12695 (directory_file_name): Don't assume string length fits in long.
12696 (make_temp_name): Don't assume pid fits in int, or that its print
12697 length is less than 20.
12699 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
12701 * coding.c (make_subsidiaries): Don't assume string length fits in int.
12703 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
12705 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
12706 We prefer signed integers, even for size calculations.
12708 * emacs.c: Don't assume string length fits in 'int'.
12709 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
12710 (main): Don't invoke strlen when not needed.
12712 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
12713 (XD_DEBUG_MESSAGE): Don't waste a byte.
12715 * callproc.c (getenv_internal_1, getenv_internal)
12716 (Fgetenv_internal):
12717 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
12719 * lread.c (invalid_syntax): Omit length argument.
12720 All uses changed. This doesn't fix a bug, but it simplifies the
12721 code away from its former Hollerith-constant appearance, and it's
12722 one less 'int' to worry about when looking at integer-overflow issues.
12723 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
12725 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
12726 This didn't break anything, but it didn't help either.
12727 It's confusing to put a bogus integer in a place where the actual
12728 value does not matter.
12729 (LIST_END_P): Remove unused macro and its bogus comment.
12730 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
12732 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
12733 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
12735 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
12736 We prefer signed types, and the value cannot exceed the EMACS_INT
12737 range anyway (because otherwise the length would not be representable).
12738 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
12739 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
12740 This avoids a GCC warning when WIDE_EMACS_INT.
12742 * indent.c (sane_tab_width): New function.
12743 (current_column, scan_for_column, Findent_to, position_indentation)
12744 (compute_motion): Use it. This is just for clarity.
12745 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
12747 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
12749 * lisp.h (lint_assume): New macro.
12750 * composite.c (composition_gstring_put_cache):
12751 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
12753 * editfns.c, insdel.c:
12754 Omit unnecessary forward decls, to simplify future changes.
12756 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
12758 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
12760 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
12761 Use much-faster test for byte-length change.
12762 Don't assume string byte-length fits in 'int'.
12763 Check that character arg fits in 'int'.
12764 (mapcar1): Declare byte as byte, for clarity.
12766 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
12768 * fns.c (concat): Catch string overflow earlier.
12769 Do not rely on integer wraparound.
12771 * dispextern.h (struct it.overlay_strings_charpos)
12772 (struct it.selective): Now EMACS_INT, not int.
12773 * xdisp.c (forward_to_next_line_start)
12774 (back_to_previous_visible_line_start)
12775 (reseat_at_next_visible_line_start, next_element_from_buffer):
12776 Don't arbitrarily truncate the value of 'selective' to int.
12778 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
12780 * composite.c: Don't truncate sizes to 'int'.
12781 (composition_gstring_p, composition_reseat_it)
12782 (composition_adjust_point): Use EMACS_INT, not int.
12783 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
12784 not EMACS_UINT, for indexes.
12786 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
12788 * buffer.c: Include <verify.h>.
12789 (struct sortvec.priority, struct sortstr.priority):
12790 Now EMACS_INT, not int.
12791 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
12792 (struct sortstr.size, record_overlay_string)
12793 (struct sortstrlist.size, struct sortlist.used):
12794 Don't truncate size to int.
12795 (record_overlay_string): Check for size-calculation overflow.
12796 (init_buffer_once): Check at compile-time, not run-time.
12798 2011-06-22 Jim Meyering <meyering@redhat.com>
12800 Don't leak an XBM-image-sized buffer
12801 * image.c (xbm_load): Free the image buffer after using it.
12803 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
12806 * composite.c (find_automatic_composition): Omit needless 'return 0;'
12807 that Sun C diagnosed.
12808 * fns.c (secure_hash): Fix pointer signedness issue.
12809 * intervals.c (static_offset_intervals): New function.
12810 (offset_intervals): Use it.
12812 2011-06-21 Leo Liu <sdl.web@gmail.com>
12815 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
12818 * fns.c (secure_hash): Rename from crypto_hash_function and change
12819 the first arg to accept symbols.
12820 (Fsecure_hash): New primitive.
12821 (syms_of_fns): New symbols.
12823 2011-06-20 Deniz Dogan <deniz@dogan.se>
12825 * process.c (Fset_process_buffer): Clarify return value in
12828 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
12830 * dispnew.c (add_window_display_history): Use BVAR.
12832 * xdisp.c (debug_method_add): Use BVAR.
12833 (check_window_end, dump_glyph_matrix, dump_glyph)
12834 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
12836 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
12839 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
12840 check till after the cache is created in init_frame_faces.
12842 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
12844 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
12846 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
12848 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
12849 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
12850 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
12852 Improve buffer-overflow checking (Bug#8873).
12853 * fileio.c (Finsert_file_contents):
12854 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
12855 Remove the old (too-loose) buffer overflow checks.
12856 They weren't needed, since make_gap checks for buffer overflow.
12857 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
12858 The old code merely checked for Emacs fixnum overflow, and relied
12859 on undefined (wraparound) behavior. The new code avoids undefined
12860 behavior, and also checks for ptrdiff_t and/or size_t overflow.
12862 * editfns.c (Finsert_char): Don't dump core with very negative counts.
12863 Tune. Don't use wider integers than needed. Don't use alloca.
12864 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
12866 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
12868 * insdel.c, lisp.h (buffer_overflow): New function.
12869 (insert_from_buffer_1, replace_range, replace_range_2):
12870 * insdel.c (make_gap_larger):
12871 * editfns.c (Finsert_char):
12872 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
12874 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
12876 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
12878 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
12880 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
12881 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
12883 * fileio.c: Don't assume EMACS_INT fits in off_t.
12884 (emacs_lseek): New static function.
12885 (Finsert_file_contents, Fwrite_region): Use it.
12886 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
12888 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
12890 * fns.c: Don't overflow int when computing a list length.
12891 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
12892 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
12893 truncation on 64-bit hosts. Check for QUIT every
12894 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
12895 faster and is responsive enough.
12896 (Flength): Report an error instead of overflowing an integer.
12897 (Fsafe_length): Return a float if the value is not representable
12898 as a fixnum. This shouldn't happen except in contrived situations.
12899 (Fnthcdr, Fsort): Don't assume list length fits in int.
12900 (Fcopy_sequence): Don't assume vector length fits in int.
12902 * alloc.c: Check that resized vectors' lengths fit in fixnums.
12903 (header_size, word_size): New constants.
12904 (allocate_vectorlike): Don't check size overflow here.
12905 (allocate_vector): Check it here instead, since this is the only
12906 caller of allocate_vectorlike that could cause overflow.
12907 Check that the new vector's length is representable as a fixnum.
12909 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
12910 The previous code was bogus. For example, next_almost_prime (32)
12911 returned 39, which is undesirable as it is a multiple of 3; and
12912 next_almost_prime (24) returned 25, which is a multiple of 5 so
12913 why was the code bothering to check for multiples of 7?
12915 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
12917 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
12919 Variadic C functions now count arguments with ptrdiff_t.
12920 This partly undoes my 2011-03-30 change, which replaced int with size_t.
12921 Back then I didn't know that the Emacs coding style prefers signed int.
12922 Also, in the meantime I found a few more instances where arguments
12923 were being counted with int, which may truncate counts on 64-bit
12924 machines, or EMACS_INT, which may be unnecessarily wide.
12925 * lisp.h (struct Lisp_Subr.function.aMANY)
12926 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
12927 Arg counts are now ptrdiff_t, not size_t.
12928 All variadic functions and their callers changed accordingly.
12929 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
12930 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
12931 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
12932 * callint.c (Fcall_interactively): Check arg count for overflow,
12933 to avoid potential buffer overrun. Use signed char, not 'int',
12934 for 'varies' array, so that we needn't bother to check its size
12935 calculation for overflow.
12936 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
12937 * eval.c (apply_lambda):
12938 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
12939 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
12940 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
12942 * callint.c (Fcall_interactively): Don't use index var as event count.
12944 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
12945 * mem-limits.h (SIZE): Remove; no longer used.
12947 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
12949 Remove unnecessary casts.
12950 * xterm.c (x_term_init):
12951 * xfns.c (x_set_border_pixel):
12952 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
12953 These aren't needed now that we assume ANSI C.
12955 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
12956 It's more likely to cause problems (due to unsigned overflow)
12959 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
12961 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
12963 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
12965 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
12967 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
12969 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
12971 GLYPH_CODE_FACE returns EMACS_INT, not int.
12972 * dispextern.h (merge_faces):
12973 * xfaces.c (merge_faces):
12974 * xdisp.c (get_next_display_element, next_element_from_display_vector):
12975 Don't assume EMACS_INT fits in int.
12977 * character.h (CHAR_VALID_P): Remove unused parameter.
12978 * fontset.c, lisp.h, xdisp.c: All uses changed.
12980 * editfns.c (Ftranslate_region_internal): Omit redundant test.
12982 * fns.c (concat): Minor tuning based on overflow analysis.
12983 This doesn't fix any bugs. Use int to hold character, instead
12984 of constantly refetching from Emacs object. Use XFASTINT, not
12985 XINT, for value known to be a character. Don't bother comparing
12986 a single byte to 0400, as it's always less.
12988 * floatfns.c (Fexpt):
12989 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
12991 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
12994 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
12996 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
12997 Without this fix, on a 64-bit host (aset S 0 4294967386) would
12998 incorrectly succeed when S was a string, because 4294967386 was
12999 truncated before it was used.
13001 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13002 Otherwise, an out-of-range integer could cause undefined behavior
13005 * composite.c: Use int, not EMACS_INT, for characters.
13006 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13007 EMACS_INT, for values that are known to be in character range.
13008 This doesn't fix any bugs but is the usual style inside Emacs and
13009 may generate better code on 32-bit machines.
13011 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13012 This is for reasons similar to the recent CHAR_STRING fix.
13013 * charset.c (Fencode_char): Check that character arg is actually
13014 a character. Pass an int to ENCODE_CHAR.
13015 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13016 wider than 'int', as a compile-time check to prevent future regressions
13019 * character.c (char_string): Remove unnecessary casts.
13021 Make sure a 64-bit char is never passed to CHAR_STRING.
13022 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13023 by silently ignoring the top 32 bits, allowing some values
13024 that were far too large to be valid characters.
13025 * character.h: Include <verify.h>.
13026 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13027 arguments are no wider than unsigned, as a compile-time check
13028 to prevent future regressions in this area.

13034 Adjust to CHAR_STRING's new requirement.
13035 * editfns.c (Finsert_char, Fsubst_char_in_region):
13036 * fns.c (concat): Check that character args are actually
13037 characters. Without this test, these functions did the wrong
13038 thing with wildly out-of-range values on 64-bit hosts.
13040 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13041 These casts should not be needed on 32-bit hosts, either.
13042 * keyboard.c (read_char):
13043 * lread.c (Fload): Remove casts to unsigned.
13045 * lisp.h (UNSIGNED_CMP): New macro.

13053 * keyboard.c (read_char): Use UNSIGNED_CMP.
13055 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
13056 not to EMACS_INT, to avoid GCC warning.
13058 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13060 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13061 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
13062 isn't needed on 32-bit machines.
13064 * buffer.c (Fgenerate_new_buffer_name):
13065 Use EMACS_INT for count, not int.
13066 (advance_to_char_boundary): Return EMACS_INT, not int.

13085 (total_free_floats, total_floats, total_free_intervals)
13086 (total_intervals, total_strings, total_free_strings):
13087 Now EMACS_INT, not int. All uses changed.
13088 (Fgarbage_collect): Compute overall total using a double, so that
13089 integer overflow is less likely to be a problem. Check for overflow
13090 when converting back to an integer.
13091 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
13092 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
13093 These were 'int' variables that could overflow on 64-bit hosts;
13094 they were never used, so remove them instead of repairing them.
13095 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
13096 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
13097 Previously, this ceilinged at INT_MAX, but that doesn't work on
13099 (allocate_pseudovector): Don't use EMACS_INT when int would do.
13101 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
13102 (allocate_vectorlike): Check for ptrdiff_t overflow.
13103 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13104 when a (possibly-narrower) signed value would do just as well.
13105 We prefer using signed arithmetic, to avoid comparison confusion.
13107 * alloc.c: Catch some string size overflows that we were missing.
13108 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
13109 for convenience in STRING_BYTES_MAX.
13110 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
13111 The definition here is exact; the one in lisp.h was approximate.
13112 (allocate_string_data): Check for string overflow. This catches
13113 some instances we weren't catching before. Also, it catches
13114 size_t overflow on (unusual) hosts where SIZE_MAX <= min
13115 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
13116 and ptrdiff_t and EMACS_INT are both 64 bits.
13118 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
13119 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
13120 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
13122 * character.c (string_escape_byte8): Fix nbytes/nchars typo.

13697 instead of using explicit *_CHAR codes.
13698 (bidi_resolve_explicit, bidi_resolve_weak):

13707 (bidi_level_of_next_char): Don't try to lookup the cache for the
13708 next/previous character if nothing is cached there yet, or if we
13709 were just reseat()'ed to a new position.
13711 * xdisp.c (set_cursor_from_row): Set start and stop points
13712 according to the row's direction when priming the loop that looks
13713 for the glyph on which to display cursor.

13715 (display_prop_intangible_p): Reimplement to call
13716 handle_display_spec instead of single_display_spec_intangible_p.
13717 Accept 3 additional arguments needed by handle_display_spec.
13718 This fixes incorrect cursor motion across display property with complex
13719 values: lists, `(when COND...)' forms, etc.

13727 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
13728 value of a `display' property is a "replacing spec".
13729 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
13730 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
13731 the display property, but just return a value indicating whether
13732 the display property will replace the characters it covers.
13733 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
13734 frame_window_p members of struct bidi_it.
13735 (compute_display_string_pos, compute_display_string_end):

13760 * gnutls.c: Use Emacs's memory allocators.
13761 Without this change, the gnutls library would invoke malloc etc.
13762 directly, which causes problems on non-SYNC_INPUT hosts, and which
13763 runs afoul of improving memory_full behavior. (Bug#8761)
13764 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
13765 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
13766 xfree instead of the default malloc, realloc, free.
13767 (Fgnutls_boot): No need to check for memory allocation failure,
13768 since xmalloc does that for us.

13791 for hashes and hash indexes, instead of 'unsigned' and 'int'.
13792 * alloc.c (allocate_vectorlike):
13793 Check for overflow in vector size calculations.
13794 * ccl.c (ccl_driver):
13795 Check for overflow when converting EMACS_INT to int.

13797 need to be updated by these changes.
13798 * fns.c (make_hash_table, maybe_resize_hash_table):
13799 Check for integer overflow with large hash tables.
13800 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
13801 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
13802 (SXHASH_REDUCE): New macro.
13803 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
13804 Use it instead of discarding useful hash info with large hash values.
13805 (sxhash_float): New function.
13806 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
13807 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
13808 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
13809 Rewrite to use FIXNUM_BITS, as this simplifies things.
13810 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
13811 Adjust signatures to match updated version of code.
13812 (consing_since_gc): Now EMACS_INT, since a single hash table can
13813 use more than INT_MAX bytes.

13862 Make it possible to run ./temacs.
13864 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
13865 syms_of_callproc does the same thing. Remove test for

13894 * image.c: Various fixes to ImageMagick code comments.
13895 (Fimagemagick_types): Doc fix.
13897 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
13899 Minor fixes prompted by GCC 4.6.0 warnings.
13901 * xselect.c (converted_selections, conversion_fail_tag): Now static.
13903 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
13904 (x_clipboard_manager_save_all): Move extern decl to ...
13905 * xterm.h: ... here, so that it can be checked for consistency.
13907 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
13909 * xselect.c (x_clipboard_manager_save_frame)
13910 (x_clipboard_manager_save_all): New functions.
13911 (Fx_clipboard_manager_save): Lisp function deleted.
13913 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
13914 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
13916 * xterm.h: Update prototype.
13918 2011-05-28 William Xu <william.xwl@gmail.com>
13920 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
13921 exiting (Bug#8239).
13923 2011-05-28 Jim Meyering <meyering@redhat.com>
13925 Avoid a sign-extension bug in crypto_hash_function.
13926 * fns.c (to_uchar): Define.
13927 (crypto_hash_function): Use it to convert some newly-signed
13928 variables to unsigned, to avoid sign-extension bugs. For example,
13929 without this change, (md5 "truc") would evaluate to
13930 45723a2aff78ff4fff7fff1114760e62 rather than the expected
13931 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
13932 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
13934 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13936 Integer overflow fixes.
13938 * dbusbind.c: Serial number integer overflow fixes.
13939 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
13940 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
13941 to hold a serial number that is too large for a fixnum.
13942 (Fdbus_method_return_internal, Fdbus_method_error_internal):
13943 Check for serial numbers out of range. Decode any serial number
13944 that was so large that it became a float. (Bug#8722)
13946 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
13947 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13948 Use XFASTINT rather than XUINT when numbers are nonnegative.
13949 (xd_append_arg, Fdbus_method_return_internal):
13950 (Fdbus_method_error_internal): Likewise. Also, for unsigned
13951 arguments, check that Lisp number is nonnegative, rather than
13952 silently wrapping negative numbers around. (Bug#8722)
13953 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
13956 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
13958 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
13960 ccl: Add integer overflow checks.
13961 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
13962 (IN_INT_RANGE): New macros.
13963 (ccl_driver): Use them to check for integer overflow when
13964 decoding a CCL program. Many of the new checks are whether XINT (x)
13965 fits in int; it doesn't always, on 64-bit hosts. The new version
13966 doesn't catch all possible integer overflows, but it's an
13967 improvement. (Bug#8719)
13969 * alloc.c (make_event_array): Use XINT, not XUINT.
13970 There's no need for unsigned here.
13972 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
13973 This follows up to the 2011-05-06 change that substituted uintptr_t
13974 for EMACS_INT. This case wasn't caught back then.
13976 Rework Fformat to avoid integer overflow issues.
13977 * editfns.c: Include <float.h> unconditionally, as it's everywhere
13978 now (part of C89). Include <verify.h>.
13979 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
13980 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
13981 (Fformat): Avoid the prepass trying to compute sizes; it was only
13982 approximate and thus did not catch overflow reliably. Instead, walk
13983 through the format just once, formatting and computing sizes as we go,
13984 checking for integer overflow at every step, and allocating a larger
13985 buffer as needed. Keep track separately whether the format is
13986 multibyte. Keep only the most-recently calculated precision, rather
13987 than them all. Record whether each argument has been converted to
13988 string. Use EMACS_INT, not int, for byte and char and arg counts.
13989 Support field widths and precisions larger than INT_MAX. Avoid
13990 sprintf's undefined behavior with conversion specifications such as %#d
13991 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
13992 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
13993 formatting out-of-range floating point numbers with int
13994 formats. (Bug#8668)
13996 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
13998 * data.c: Avoid integer truncation in expressions involving floats.
13999 * data.c: Include <intprops.h>.
14000 (arith_driver): When there's an integer overflow in an expression
14001 involving floating point, convert the integers to floating point
14002 so that the resulting value does not suffer from catastrophic
14003 integer truncation. For example, on a 64-bit host (* 4
14004 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14005 Do not rely on undefined behavior after integer overflow.
14007 merge count_size_as_multibyte, parse_str_to_multibyte
14008 * character.c, character.h (count_size_as_multibyte):
14009 Rename from parse_str_to_multibyte; all uses changed.
14010 Check for integer overflow.
14011 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14012 since it's now a duplicate of the other. This is more of
14013 a character than a buffer op, so better that it's in character.c.
14014 * fns.c, print.c: Adjust to above changes.
14016 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14018 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14020 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14022 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14023 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14024 (x_clipboard_manager_save): Now static.
14025 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14027 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14028 (crypto_hash_function): Now static.
14029 Fix pointer signedness problems. Avoid unnecessary initializations.
14031 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14033 * termhooks.h (Vselection_alist): Make it terminal-local.
14035 * terminal.c (create_terminal): Initialize it.
14037 * xselect.c: Support for clipboard managers.
14038 (Vselection_alist): Move to termhooks.h as terminal-local var.
14039 (LOCAL_SELECTION): New macro.
14040 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14041 (symbol_to_x_atom): Remove gratuitous arg.
14042 (x_handle_selection_request, lisp_data_to_selection_data)
14043 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14044 (x_own_selection, x_get_local_selection, x_convert_selection):
14045 New arg, specifying work frame. Use terminal-local Vselection_alist.
14046 (some_frame_on_display): Delete unused function.
14047 (Fx_own_selection_internal, Fx_get_selection_internal)
14048 (Fx_disown_selection_internal, Fx_selection_owner_p)
14049 (Fx_selection_exists_p): New optional frame arg.
14050 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14051 (x_handle_selection_clear): Don't treat other terminals with the
14052 same keyboard specially. Use the terminal-local Vselection_alist.
14053 (x_clear_frame_selections): Use Frun_hook_with_args.
14055 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14057 * xterm.h: Add support for those atoms.
14059 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14061 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14062 (converted_selections, conversion_fail_tag): New global variables.
14063 (x_selection_request_lisp_error): Free the above.
14064 (x_get_local_selection): Remove unnecessary code.
14065 (x_reply_selection_request): Args changed; handle arbitrary array
14066 of converted selections stored in converted_selections.
14067 Separate the XChangeProperty and SelectionNotify steps.
14068 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14069 (x_convert_selection): New function.
14070 (x_handle_selection_event): Simplify.
14071 (x_get_foreign_selection): Don't ignore incoming requests while
14072 waiting for an answer; this will fail when we implement
14073 SAVE_TARGETS, and seems unnecessary anyway.
14074 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14075 (Vx_sent_selection_functions): Doc fix.
14077 2011-05-26 Leo Liu <sdl.web@gmail.com>
14079 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14081 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14083 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14085 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14086 for fringe update if it has periodic bitmap.
14087 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14088 and fringe_bitmap_periodic_p.
14090 * fringe.c (get_fringe_bitmap_data): New function.
14091 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14092 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14093 row. Mark glyph row for fringe update if periodicity changed.
14095 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14096 for fringe update unless it has periodic bitmap.
14098 2011-05-25 Kenichi Handa <handa@m17n.org>
14100 * xdisp.c (get_next_display_element): Set correct it->face_id for
14101 a static composition.
14103 2011-05-24 Leo Liu <sdl.web@gmail.com>
14106 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
14108 * fns.c (crypto_hash_function, Fsha1): New function.
14109 (Fmd5): Use crypto_hash_function.
14110 (syms_of_fns): Add Ssha1.
14112 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14114 * gnutls.c: Remove unused macros.
14115 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14116 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14117 Remove macros that are defined and never used.
14118 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14120 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14122 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14123 (Fx_get_selection_internal): Minor cleanup.
14124 (Fx_own_selection_internal): Rename arguments for consistency with
14127 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14129 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
14131 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14133 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
14135 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14137 * dispnew.c (scrolling_window): Don't exclude the case that the
14138 last enabled row in the desired matrix touches the bottom boundary.
14140 2011-05-21 Glenn Morris <rgm@gnu.org>
14142 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
14143 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
14144 and add some more files.
14146 2011-05-20 Eli Zaretskii <eliz@gnu.org>
14148 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
14149 report_file_error introduced by the change from 2011-05-07.
14151 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14153 * systime.h (Time): Define only if emacs is defined.
14154 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14155 where the include path doesn't have X11/X.h by default. See
14156 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14158 2011-05-20 Kenichi Handa <handa@m17n.org>
14160 * composite.c (find_automatic_composition): Fix previous change.
14162 2011-05-20 Glenn Morris <rgm@gnu.org>
14164 * lisp.mk: New file, split from Makefile.in.
14165 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14166 (shortlisp): Remove.
14167 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14169 2011-05-19 Glenn Morris <rgm@gnu.org>
14171 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14172 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14173 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14174 (lisp): Set the order to that of loadup.el.
14175 (shortlisp): Make it a copy of $lisp.
14176 (SOME_MACHINE_LISP): Remove.
14177 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14178 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14180 2011-05-18 Kenichi Handa <handa@m17n.org>
14182 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14183 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14184 (find_automatic_composition): Mostly rewrite for efficiency.
14186 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14188 * makefile.w32-in: Update dependencies.
14190 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14192 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14193 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14195 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14197 Fix some integer overflow issues, such as string length overflow.
14199 * insdel.c (count_size_as_multibyte): Check for string overflow.
14201 * character.c (lisp_string_width): Check for string overflow.
14202 Use EMACS_INT, not int, for string indexes and lengths; in
14203 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14204 the resulting string length overflows an EMACS_INT; instead,
14205 report a string overflow if no precision given. When checking for
14206 precision exhaustion, use a check that cannot possibly have
14207 integer overflow. (Bug#8675)
14208 * character.h (lisp_string_width): Adjust to new signature.
14210 * alloc.c (string_overflow): New function.
14211 (Fmake_string): Use it. This doesn't change behavior, but saves
14212 a few bytes and will simplify future changes.
14213 * character.c (string_escape_byte8): Likewise.
14214 * lisp.h (string_overflow): New decl.
14216 Fixups, following up to the user-interface timestamp change.
14217 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14218 for UI timestamps, instead of unsigned long.
14219 * msdos.c (mouse_get_pos): Likewise.
14220 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14221 * w32gui.h (Time): Define by including "systime.h" rather than by
14222 declaring it ourselves. (Bug#8664)
14224 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14225 * image.c (clear_image_cache): Likewise.
14227 * term.c (term_mouse_position): Don't assume time_t wraparound.
14229 Be more systematic about user-interface timestamps.
14230 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14231 and sometimes 'EMACS_UINT', to represent these timestamps.
14232 This change causes it to use 'Time' uniformly, as that's what X uses.
14233 This makes the code easier to follow, and makes it easier to catch
14234 integer overflow bugs such as Bug#8664.
14235 * frame.c (Fmouse_position, Fmouse_pixel_position):
14236 Use Time, not unsigned long, for user-interface timestamps.
14237 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14238 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14239 * keyboard.h (last_event_timestamp): Likewise.
14240 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14241 * menu.h (xmenu_show): Likewise.
14242 * term.c (term_mouse_position): Likewise.
14243 * termhooks.h (struct input_event.timestamp): Likewise.
14244 (struct terminal.mouse_position_hook): Likewise.
14245 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14246 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14247 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14248 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14249 what it was before.
14250 * menu.h, termhooks.h: Include "systime.h", for Time.
14252 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14253 Don't assume that the difference between two unsigned long values
14254 can fit into an integer. At this point, we know button_down_time
14255 <= event->timestamp, so the difference must be nonnegative, so
14256 there's no need to cast the result if double-click-time is
14257 nonnegative, as it should be; check that it's nonnegative, just in
14258 case. This bug is triggered when events are more than 2**31 ms
14259 apart (about 25 days). (Bug#8664)
14261 * xselect.c (last_event_timestamp): Remove duplicate decl.
14262 (x_own_selection): Remove needless cast to unsigned long.
14264 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14265 that always fit in int. Use a sentinel instead of a counter, to
14266 avoid a temp and to allay GCC's concerns about possible int overflow.
14267 * frame.h (struct frame): Use int for menu_bar_items_used
14268 instead of EMACS_INT, since it always fits in int.
14270 * menu.c (grow_menu_items): Check for int overflow.
14272 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14274 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14275 Before, the code was not consistent. These values cannot exceed
14276 2**31 - 1 so there's no need to make them unsigned.
14277 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14278 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14279 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14281 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14283 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14284 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14285 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14286 presumably because the widths might not match.
14288 * window.c (size_window): Avoid needless test at loop start.
14290 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14292 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14294 2011-05-12 Drew Adams <drew.adams@oracle.com>
14296 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14298 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14300 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14301 `width' to `bar_area_x' and `bar_area_width', respectively.
14302 (x_scroll_run): Take account of fringe background extension.
14304 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14305 Rename local vars `left' and `width' to `bar_area_x' and
14306 `bar_area_width', respectively.
14307 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14308 background extension.
14310 2011-05-10 Jim Meyering <meyering@redhat.com>
14312 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14314 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14316 * image.c (Finit_image_library): Return t for built-in image types,
14317 like pbm and xbm. (Bug#8640)
14319 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14321 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14323 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14325 * w32console.c (Fset_screen_color): Doc fix.
14326 (Fget_screen_color): New function.
14327 (syms_of_ntterm): Defsubr it.
14329 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14330 unlink the temporary file if Fcall_process didn't create it in the
14332 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14333 child process will be redirected to a file specified with `:file'.
14334 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14335 cue to call_process_cleanup not to close that handle.
14337 2011-05-07 Ben Key <bkey76@gmail.com>
14339 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14340 one of two shell specific rules, either bootstrap-temacs-CMD or
14341 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14342 to the previous implementation of the bootstrap-temacs rule.
14343 The bootstrap-temacs-CMD rule is similar to the previous
14344 implementation of the bootstrap-temacs rule except that it
14345 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14348 These changes, along with some changes to nt/configure.bat,
14349 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14350 earlier fix to add support for --cflags and --ldflags options
14351 that include quotes so that it works whether make uses cmd or
14354 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14356 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14357 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14359 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14360 a string. Handle both cases.
14361 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14362 (Fdbus_register_method): Use Qinvalid_function.
14364 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14366 * makefile.w32-in: Update dependencies.
14367 (LISP_H): Add inttypes.h and stdin.h.
14368 (PROCESS_H): Add unistd.h.
14370 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14372 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14373 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14375 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14377 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14379 * term.c (vfatal): Remove stray call to va_end.
14380 It's not needed and the C Standard doesn't allow it here anyway.
14382 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14383 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14385 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14388 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14390 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14392 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14394 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14396 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14398 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14399 * charset.c (Fdefine_charset_internal): Don't initialize
14400 charset.code_space[15]. The value was garbage, on hosts with
14401 32-bit int (Bug#8600).
14403 * lread.c (read_integer): Be more consistent with string-to-number.
14404 Use string_to_number to do the actual conversion; this avoids
14405 rounding errors and fixes some other screwups. Without this fix,
14406 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14407 (digit_to_number): Move earlier, for benefit of read_integer.
14408 Return -1 if the digit is out of range for the base, -2 if it is
14409 not a digit in any supported base. (Bug#8602)
14411 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14413 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14414 to match comment at start of function. This also removes a
14415 GCC warning about overflow in a 32+64-bit port.
14417 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14419 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14420 Reported by Stefan Monnier in
14421 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14422 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14423 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14425 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14426 (EMACS_UINTPTR): Likewise, with uintptr_t.
14428 * lisp.h: Prefer 64-bit EMACS_INT if available.
14429 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14430 on 32-bit hosts that have 64-bit int, so that they can access
14432 However, temporarily disable this change unless the temporary
14433 symbol WIDE_EMACS_INT is defined.
14435 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14437 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14438 This removes an assumption that EMACS_INT and long are the same
14439 width as pointers. The assumption is true for Emacs porting targets
14440 now, but we want to make other targets possible.
14441 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14442 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14443 In the rest of the code, change types of integers that hold casted
14444 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14445 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14446 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14447 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14448 No need to cast type when ORing.
14449 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14450 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14451 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14452 assume EMACS_INT is the same width as char *.
14453 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14454 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14455 Remove no-longer-needed casts.
14456 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14457 (xg_tool_bar_help_callback, xg_make_tool_item):
14458 Use EMACS_INTPTR to hold an integer
14459 that will be cast to void *; this can avoid a GCC warning
14460 if EMACS_INT is not the same width as void *.
14461 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14462 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14463 (current_message_1, set_message_1):
14464 Use a local to convert to proper width without a cast.
14465 * xmenu.c (dialog_selection_callback): Likewise.
14467 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14468 Also, don't assume VALBITS / RAND_BITS is less than 5,
14469 and don't rely on undefined behavior when shifting a 1 left into
14471 * lisp.h (get_random): Change signature to match.
14473 * lread.c (hash_string): Use size_t, not int, for hash computation.
14474 Normally we prefer signed values; but hashing is special, because
14475 it's better to use unsigned division on hash table sizes so that
14476 the remainder is nonnegative. Also, size_t is the natural width
14477 for hashing into memory. The previous code used 'int', which doesn't
14478 retain enough info to hash well into very large tables.
14479 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14481 * dbusbind.c: Don't possibly lose pointer info when converting.
14482 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14483 Use XPNTR rather than XHASH, so that the high-order bits of
14484 the pointer aren't lost when converting through void *.
14486 * eval.c (Fautoload): Don't double-shift a pointer.
14488 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14490 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14492 * gnutls.c (DEF_GNUTLS_FN):
14493 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14495 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14497 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14500 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14502 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14503 New version that can reserve upto 2GB of heap space.
14505 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14507 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14509 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14511 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14512 `gnutls_certificate_set_x509_key_file'.
14514 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
14516 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
14517 Update dependencies.
14519 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14521 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14522 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14523 Remove unused parameter `fildes'.
14524 * process.c (read_process_output, send_process): Don't pass it.
14526 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14528 Fix previous change: the library cache is defined in w32.c.
14529 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14530 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14532 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14534 Implement dynamic loading of GnuTLS on Windows.
14536 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14537 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14538 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14541 * gnutls.c (Qgnutls_dll): Define.
14542 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
14543 (gnutls_*): Declare function pointers.
14544 (init_gnutls_functions): New function to initialize function pointers.

14546 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
14547 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14548 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
14549 (emacs_gnutls_write, emacs_gnutls_read)
14550 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14551 (Fgnutls_available_p): New function.
14552 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
14553 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
14554 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
14556 * image.c: Include w32.h.
14557 (Vimage_type_cache): Delete.

14560 (w32_delayed_load): Move to w32.c.
14562 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
14564 * w32.c (QCloaded_from, Vlibrary_cache): Define.
14565 (w32_delayed_load): Move from image.c. When loading a library, record
14566 its filename in the :loaded-from property of the library id.
14567 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
14568 Initialize and staticpro them.
14569 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
14571 * process.c: Include lisp.h before w32.h, not after.
14572 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
14573 instead of gnutls_record_check_pending.
14575 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
14577 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
14579 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
14580 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
14583 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
14585 * xterm.c (x_set_frame_alpha): Do not set property on anything
14586 else than FRAME_X_OUTER_WINDOW (Bug#8608).
14588 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14590 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
14592 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14594 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

14604 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
14606 * callproc.c: Indentation fixup.
14608 * sysdep.c (wait_for_termination_1): Make static.
14609 (wait_for_termination, interruptible_wait_for_termination):
14610 Move after wait_for_termination_1.
14612 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
14614 * sysdep.c (interruptible_wait_for_termination): New function
14615 which is like wait_for_termination, but allows keyboard
14618 * callproc.c (Fcall_process): Add (:file "file") as an option for
14620 (Fcall_process_region): Ditto.
14622 2011-04-30 Eli Zaretskii <eliz@gnu.org>
14624 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
14625 rather than `XVECTOR (FOO)->size'.
14627 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
14628 inttypes.h, as a gnulib replacement is used if it not available in
14631 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14633 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
14634 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
14635 of MOST_POSITIVE_FIXNUM. (Bug#8528)
14637 * coding.c (coding_alloc_by_realloc): Error out if destination
14638 will grow beyond MOST_POSITIVE_FIXNUM.
14639 (decode_coding_emacs_mule): Abort if there isn't enough place in
14640 charbuf for the composition carryover bytes. Reserve an extra
14641 space for up to 2 characters produced in a loop.
14642 (decode_coding_iso_2022): Abort if there isn't enough place in
14643 charbuf for the composition carryover bytes.
14645 2011-04-21 Eli Zaretskii <eliz@gnu.org>

14648 aborting when %lld or %lll format is passed.
14649 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
14650 %llo or %llx format is passed. (Bug#8545)
14652 * window.c (window_scroll_line_based): Use a marker instead of
14653 simple variables to record original value of point. (Bug#7952)
14655 * doprnt.c (doprnt): Fix the case where a multibyte sequence
14656 produced by %s or %c overflows available buffer space. (Bug#8545)
14658 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
14660 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
14661 (SIZE_MAX): Move defn after all includes, as they might #define it.
14663 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14665 * w32.c (init_environment): Warn about defaulting HOME to C:\.

14675 2011-04-28 Eli Zaretskii <eliz@gnu.org>
14677 * doprnt.c (doprnt): Don't return value smaller than the buffer
14678 size if the message was truncated. (Bug#8545).
14680 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14682 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

14685 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14687 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
14689 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
14691 * makefile.w32-in: Update dependencies.
14693 2011-04-27 Eli Zaretskii <eliz@gnu.org>
14695 Improve `doprnt' and its usage. (Bug#8545)
14696 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
14697 `format_end'. Remove support for %l as a conversion specifier.
14698 Don't use xrealloc. Improve diagnostics when the %l size modifier
14699 is used. Update the commentary.
14701 * eval.c (verror): Simplify calculation of size_t.
14703 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
14706 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
14708 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
14711 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14713 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
14714 This makes this file independent of the recent pseudovector change.
14716 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
14718 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
14720 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
14721 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
14722 Remove unused local.
14723 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
14725 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
14726 GCC 4.6.0 optimizes based on type-based alias analysis.
14727 For example, if b is of type struct buffer * and v of type struct
14728 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
14729 != &v->size, and therefore "v->size = 1; b->size = 2; return
14730 v->size;" must therefore return 1. This assumption is incorrect
14731 for Emacs, since it type-puns struct Lisp_Vector * with many other
14732 types. To fix this problem, this patch adds a new type struct
14733 vectorlike_header that documents the constraints on layout of vectors
14734 and pseudovectors, and helps optimizing compilers not get fooled
14735 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
14736 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
14737 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
14739 (XSETPVECTYPE): Rewrite in terms of new macro.
14740 (XSETPVECTYPESIZE): New macro, specifying both type and size.
14741 This is a bit clearer, and further avoids the possibility of
14742 undesirable aliasing.
14743 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
14744 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
14745 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
14746 since Lisp_Subr is a special case (no "next" field).
14747 (ASIZE): Now uses header.size rather than size.
14748 All previous uses of XVECTOR (foo)->size replaced to use this macro,
14749 to avoid the hassle of writing XVECTOR (foo)->header.size.
14750 (struct vectorlike_header): New type.
14751 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
14752 object, to help avoid aliasing.
14753 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
14754 (SUBRP): Likewise, since Lisp_Subr is a special case.
14755 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
14756 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
14757 (struct Lisp_Hash_Table): Combine first two members into a single
14758 struct vectorlike_header member. All uses of "size" and "next" members
14759 changed to be "header.size" and "header.next".
14760 * buffer.h (struct buffer): Likewise.
14761 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
14762 * frame.h (struct frame): Likewise.
14763 * process.h (struct Lisp_Process): Likewise.
14764 * termhooks.h (struct terminal): Likewise.
14765 * window.c (struct save_window_data, struct saved_window): Likewise.
14766 * window.h (struct window): Likewise.
14767 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
14768 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
14769 * buffer.c (init_buffer_once): Likewise.
14770 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
14772 * process.c (Fformat_network_address): Use local var for size,
14775 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
14777 Make the Lisp reader and string-to-float more consistent (Bug#8525)
14778 * data.c (atof): Remove decl; no longer used or needed.
14779 (digit_to_number): Move to lread.c.
14780 (Fstring_to_number): Use new string_to_number function, to be
14781 consistent with how the Lisp reader treats infinities and NaNs.
14782 Do not assume that floating-point numbers represent EMACS_INT
14783 without losing information; this is not true on most 64-bit hosts.
14784 Avoid double-rounding errors, by insisting on integers when
14785 parsing non-base-10 numbers, as the documentation specifies.
14786 * lisp.h (string_to_number): New decl, replacing ...
14787 (isfloat_string): Remove.
14788 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
14789 (read1): Do not accept +. and -. as integers; this
14790 appears to have been a coding error. Similarly, do not accept
14791 strings like +-1e0 as floating point numbers. Do not report
14792 overflow for integer overflows unless the base is not 10 which
14793 means we have no simple and reliable way to continue.
14794 Break out the floating-point parsing into a new
14795 function string_to_number, so that Fstring_to_number parses
14796 floating point numbers consistently with the Lisp reader.
14797 (digit_to_number): Move here from data.c. Make it static inline.
14798 (E_CHAR, EXP_INT): Remove, replacing with ...
14799 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
14800 (string_to_number): New function, replacing isfloat_string.
14801 This function checks for valid syntax and produces the resulting
14802 Lisp float number too. Rework it so that string-to-number
14803 no longer mishandles examples like "1.0e+". Use strtoumax,
14804 so that overflow for non-base-10 numbers is reported only when
14805 there's no portable and simple way to convert to floating point.
14807 * textprop.c (set_text_properties_1): Rewrite for clarity,
14808 and to avoid GCC warning about integer overflow.
14810 * intervals.h (struct interval): Use EMACS_INT for members
14811 where EMACS_UINT might cause problems. See
14812 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
14813 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
14814 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
14816 (offset_intervals): Tell GCC not to worry about length overflow
14817 when negating a negative length.
14819 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
14820 (overrun_check_free): Likewise.
14822 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
14823 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
14826 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14827 (gnutls_make_error): Rename local to avoid shadowing.
14828 (gnutls_emacs_global_deinit): ifdef out; not used.
14829 (Fgnutls_boot): Use const for pointer to readonly storage.
14830 Comment out unused local. Fix pointer signedness problems.
14832 * lread.c (openp): Don't stuff size_t into an 'int'.
14833 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
14834 about possible signed overflow.
14836 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14837 (GDK_KEY_g): Don't define if already defined.
14838 (xg_prepare_tooltip): Avoid pointer signedness problem.
14839 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
14841 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
14842 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
14844 * xfns.c (Fx_window_property): Simplify a bit,
14845 to make a bit faster and to avoid GCC 4.6.0 warning.
14846 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
14848 * fns.c (internal_equal): Don't assume size_t fits in int.
14850 * alloc.c (compact_small_strings): Tighten assertion a little.
14852 Replace pEd with more-general pI, and fix some printf arg casts.
14853 * lisp.h (pI): New macro, generalizing old pEd macro to other
14854 conversion specifiers. For example, use "...%"pI"d..." rather
14855 than "...%"pEd"...".
14856 (pEd): Remove. All uses replaced with similar uses of pI.
14857 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
14858 * alloc.c (check_pure_size): Don't overflow by converting size to int.
14859 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
14860 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
14861 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
14862 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
14863 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
14865 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
14866 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
14867 * print.c (safe_debug_print, print_object): Likewise.
14868 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
14870 Use pI instead of if-then-else-abort. Use %p to avoid casts,
14871 avoiding the 0 flag, which is not portable.
14872 * process.c (Fmake_network_process): Use pI to avoid cast.
14873 * region-cache.c (pp_cache): Likewise.
14874 * xdisp.c (decode_mode_spec): Likewise.
14875 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
14876 behavior on 64-bit hosts with printf arg.
14877 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
14878 (x_stop_queuing_selection_requests): Likewise.
14879 (x_get_window_property): Don't truncate byte count to an 'int'
14882 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
14883 here, since it parses constructs like leading '-' and spaces,
14884 which are not wanted; and it overflows with large numbers.
14885 Instead, simply match F[0-9]+, which is what is wanted anyway.
14887 * alloc.c: Remove unportable assumptions about struct layout.
14888 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
14889 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
14890 (allocate_vectorlike, make_pure_vector): Use the new macros,
14891 plus offsetof, to remove unportable assumptions about struct layout.
14892 These assumptions hold on all porting targets that I know of, but
14893 they are not guaranteed, they're easy to remove, and removing them
14894 makes further changes easier.
14896 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
14897 This doesn't fix a bug but makes the code clearer.
14898 (string_overrun_cookie): Now const. Use initializers that
14899 don't formally overflow signed char, to avoid warnings.
14900 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
14901 can cause Emacs to crash when string overrun checking is enabled.
14902 (allocate_buffer): Don't assume sizeof (struct buffer) is a
14903 multiple of sizeof (EMACS_INT); it need not be, if
14904 alignof(EMACS_INT) < sizeof (EMACS_INT).
14905 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
14907 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

14914 supposed to be handshaking. (Bug#8556)
14915 Reported by Paul Eggert <eggert@cs.ucla.edu>.

14928 (check_string_free_list): Convert to standard C.
14930 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
14932 * w32.c (emacs_gnutls_push): Fix typo.
14934 2011-04-25 Eli Zaretskii <eliz@gnu.org>
14936 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
14937 "cast to pointer from integer of different size".
14939 Improve doprnt and its use in verror. (Bug#8545)
14940 * doprnt.c (doprnt): Document the set of format control sequences
14941 supported by the function. Use SAFE_ALLOCA instead of always
14944 * eval.c (verror): Don't limit the buffer size at size_max-1, that
14945 is one byte too soon. Don't use xrealloc; instead xfree and
14948 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
14950 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
14953 * gnutls.c: Renamed global_initialized to
14954 gnutls_global_initialized. Added internals for the
14955 :verify-hostname-error, :verify-error, and :verify-flags
14956 parameters of `gnutls-boot' and documented those parameters in the
14957 docstring. Start callback support.
14958 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
14959 unless a fatal error occurred. Call gnutls_alert_send_appropriate
14960 on error. Return error code.

15020 changes in globals.h immediately force recompilation.
15021 (TAGS): Depend on $(CURDIR)/m/intel386.h and
15022 $(CURDIR)/s/ms-w32.h.

15032 * doprnt.c: Include limits.h.
15033 (SIZE_MAX): New macro.
15034 (doprnt): Return a size_t value. 2nd arg is now size_t.
15035 Many local variables are now size_t instead of int or unsigned.
15036 Improve overflow protection. Support `l' modifier for integer
15037 conversions. Support %l conversion. Don't assume an EMACS_INT
15038 argument for integer conversions and for %c.
15040 * lisp.h (doprnt): Restore prototype.
15042 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
15043 $(SRC)/character.h.
15045 * Makefile.in (base_obj): Add back doprnt.o.
15047 * deps.mk (doprnt.o): Add back prerequisites.
15048 (callint.o): Depend on character.h.
15050 * eval.c (internal_lisp_condition_case): Include the handler
15051 representation in the error message.
15052 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
15053 when breaking from the loop.

15057 * callint.c (Fcall_interactively): When displaying error message
15058 about invalid control letter, pass the character's codepoint, not
15059 a pointer to its multibyte form. Improve display of the character
15060 in octal and display also its hex code.
15062 * character.c (char_string): Use %x to display the (unsigned)
15063 codepoint of an invalid character, to avoid displaying a bogus
15066 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15067 `error', not SYMBOL_NAME itself.
15069 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
15070 character arguments to `error'.
15072 * charset.c (check_iso_charset_parameter): Fix incorrect argument
15073 to `error' in error message about FINAL_CHAR argument. Make sure
15074 FINAL_CHAR is a character, and use %c when it is passed as

15139 Define only if needed.
15141 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
15142 by pacifying GCC about it. Maybe it's time to retire it?
15143 * xfaces.c (USG, __TIMEVAL__): Likewise.
15145 * dispextern.h (struct redisplay_interface): Rename param
15146 to avoid shadowing.
15147 * termhooks.h (struct terminal): Likewise.
15148 * xterm.c (xembed_send_message): Likewise.
15150 * insdel.c (make_gap_smaller): Define only if
15151 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
15153 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
15156 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
15157 so that we aren't warned about unused symbols.
15159 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
15161 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

15170 define if USE_GTK || USE_X_TOOLKIT.
15171 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
15172 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.

15174 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
15176 * xmenu.c (menu_help_callback): Pointer type fixes.
15177 Use const pointers when pointing at readonly data. Avoid pointer

15194 compatible char. Avoid the old compiler warnings about
15195 out-of-range initializers by using, for example, '\xab' rather
15198 * xgselect.c (xgselect_initialize): Check vs interface
15199 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

15268 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
15269 --enable-checking=xmallocoverrun). xfree is now used to
15270 deallocate these memory blocks.

15648 (message_enable_multibyte): Remove decl.
15649 (free_misc, interval_free_list, float_block, float_block_index):
15650 (n_float_blocks, float_free_list, cons_block, cons_block_index):
15651 (cons_free_list, last_marked_index):
15653 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
15654 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
15655 (mark_backtrace): Define only if BYTE_MARK_STACK.
15656 * xdisp.c (message_enable_multibyte): Now static.
15658 Declare Lisp_Object Q* variables to be 'static' if not exported.
15659 This makes it easier for human readers (and static analyzers)
15660 to see whether these variables are used from other modules.
15661 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
15662 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
15663 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
15664 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
15665 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
15666 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
15667 * xmenu.c, xselect.c:
15668 Declare Q* vars static if they are not used in other modules.
15669 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
15670 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
15671 Remove decls of unexported vars.
15672 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
15674 * lisp.h (DEFINE_FUNC): Make sname 'static'.
15676 Make Emacs functions such as Fatom 'static' by default.
15677 This makes it easier for human readers (and static analyzers)
15678 to see whether these functions can be called from other modules.
15679 DEFUN now defines a static function. To make the function external
15680 so that it can be used in other C modules, use the new macro DEFUE.
15681 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
15682 (Finit_image_library):
15683 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
15684 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
15685 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
15686 Remove decls, since these functions are now static.
15687 (Funintern, Fget_internal_run_time): New decls, since these functions
15688 were already external.
15690 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
15691 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
15692 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
15693 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
15694 * keyboard.c, keymap.c, lread.c:
15695 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
15696 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
15697 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
15698 Mark functions with DEFUE instead of DEFUN,
15699 if they are used in other modules.
15700 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
15701 decls for now-static functions.
15702 * buffer.h (Fdelete_overlay): Remove decl.
15703 * callproc.c (Fgetenv_internal): Mark as internal.
15704 * composite.c (Fremove_list_of_text_properties): Remove decl.

15707 * dired.c (Ffile_attributes): New forward static decl.
15708 * doc.c (Fdocumntation_property): New forward static decl.
15709 * eval.c (Ffetch_bytecode): New forward static decl.
15710 (Funintern): Remove extern decl; now in .h file where it belongs.
15711 * fileio.c (Fmake_symbolic_link): New forward static decl.
15712 * image.c (Finit_image_library): New forward static decl.
15713 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
15714 * intervals.h (Fprevious_property_change):
15715 (Fremove_list_of_text_properties): Remove decls.
15716 * keyboard.c (Fthis_command_keys): Remove decl.
15717 (Fcommand_execute): New forward static decl.
15718 * keymap.c (Flookup_key): New forward static decl.
15719 (Fcopy_keymap): Now static.
15720 * keymap.h (Flookup_key): Remove decl.
15721 * process.c (Fget_process): New forward static decl.
15722 (Fprocess_datagram_address): Mark as internal.
15723 * syntax.c (Fsyntax_table_p): New forward static decl.
15724 (skip_chars): Remove duplicate decl.

15726 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
15728 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
15729 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.

15733 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
15735 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
15738 2011-04-13 Eli Zaretskii <eliz@gnu.org>
15740 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
15741 when at ZV. (Bug#8487)
15743 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
15745 * charset.c (Fclear_charset_maps): Use xfree instead of free.
15747 * keyboard.c (parse_tool_bar_item): Likewise.
15748 * sound.c (sound_cleanup, alsa_close): Likewise.
15749 * termcap.c (tgetent): Likewise.
15750 * xfns.c (x_default_font_parameter): Likewise.
15751 * xsettings.c (read_and_apply_settings): Likewise.
15753 * alloc.c (overrun_check_malloc, overrun_check_realloc)
15754 (overrun_check_free): Protoize.
15756 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
15758 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
15759 since callers should never pass a negative size.
15760 Change the signature to match that of plain 'read' and 'write'; see
15761 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
15762 * lisp.h: Update prototypes of emacs_write and emacs_read.
15764 2011-04-11 Eli Zaretskii <eliz@gnu.org>
15766 * xdisp.c (redisplay_window): Don't try to determine the character
15767 position of the scroll margin if the window start point w->startp
15768 is outside the buffer's accessible region. (Bug#8468)
15770 2011-04-10 Eli Zaretskii <eliz@gnu.org>
15772 Fix write-region and its subroutines for buffers > 2GB.
15773 * fileio.c (a_write, e_write): Modify declaration of arguments and
15774 local variables to support buffers larger than 2GB.
15775 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
15777 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
15778 argument, local variables, and return value.
15780 * lisp.h: Update prototypes of emacs_write and emacs_read.
15782 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
15784 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
15786 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
15788 Fix more problems found by GCC 4.6.0's static checks.
15790 * xdisp.c (vmessage): Use a better test for character truncation.
15792 * charset.c (load_charset_map): <, not <=, for optimization,
15793 and to avoid potential problems with integer overflow.
15794 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
15795 * casetab.c (set_identity, shuffle): Likewise.
15796 * editfns.c (Fformat): Likewise.
15797 * syntax.c (skip_chars): Likewise.
15799 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
15800 This also lets GCC 4.6.0 generate slightly better loop code.
15802 * callint.c (Fcall_interactively): <, not <=, for optimization.
15803 (Fcall_interactively): Count the number of arguments produced,
15804 not the number of arguments given. This is simpler and lets GCC
15805 4.6.0 generate slightly better code.
15807 * ftfont.c: Distingish more carefully between FcChar8 and char.
15808 The previous code passed unsigned char * to a functions like
15809 strlen and xstrcasecmp that expect char *, which does not
15810 conform to the C standard.
15811 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
15812 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
15813 char * when the C standard requires it.
15815 * keyboard.c (read_char): Remove unused var.
15817 * eval.c: Port to Windows vsnprintf (Bug#8435).
15818 Include <limits.h>.
15819 (SIZE_MAX): Define if the headers do not.
15820 (verror): Do not give up if vsnprintf returns a negative count.
15821 Instead, grow the buffer. This ports to Windows vsnprintf, which
15822 does not conform to C99. Problem reported by Eli Zaretskii.
15823 Also, simplify the allocation scheme, by avoiding the need for
15824 calling realloc, and removing the ALLOCATED variable.
15826 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
15828 Remove invocations of doprnt, as Emacs now uses vsnprintf.
15829 But keep the doprint source code for now, as we might revamp it
15830 and use it again (Bug#8435).
15831 * lisp.h (doprnt): Remove.
15832 * Makefile.in (base_obj): Remove doprnt.o.
15833 * deps.mk (doprnt.o): Remove.
15835 error: Print 32- and 64-bit integers portably (Bug#8435).
15836 Without this change, on typical 64-bit hosts error ("...%d...", N)
15837 was used to print both 32- and 64-bit integers N, which relied on
15838 undefined behavior.
15839 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
15840 * lisp.h (error, verror): Mark as printf-like functions.
15841 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
15842 Report overflow in size calculations when allocating printf buffer.
15843 Do not truncate output string at its first null byte.
15844 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
15845 Truncate the output at a character boundary, since vsnprintf does not
15847 * charset.c (check_iso_charset_parameter): Convert internal
15848 character to string before calling 'error', since %c now has the
15850 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
15851 overflow when computing char to be passed to 'error'. Do not
15852 pass Lisp_Object to 'error'; pass the integer instead.
15853 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
15854 formatted with plain %d.
15856 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
15858 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
15860 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
15862 * xterm.c (x_catch_errors): Remove duplicate declaration.
15864 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
15866 * xdisp.c, lisp.h (message_nolog): Remove; unused.
15868 2011-04-10 Jim Meyering <meyering@redhat.com>
15870 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
15871 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
15872 return ssize_t not "int", and use size_t as the buffer length.
15873 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
15874 * gnutls.h: Update declarations.
15875 * process.c (read_process_output): Use ssize_t, to match.
15876 (send_process): Likewise.
15878 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15880 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
15882 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15884 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
15885 Use unsigned char, to match FcChar8 type definition.
15887 * xterm.c (handle_one_xevent):
15888 * xmenu.c (create_and_show_popup_menu):
15889 * xselect.c (x_decline_selection_request)
15890 (x_reply_selection_request): Avoid type-punned deref of X events.
15892 2011-04-09 Eli Zaretskii <eliz@gnu.org>
15894 Fix some uses of `int' instead of EMACS_INT.
15895 * search.c (string_match_1, fast_string_match)
15896 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
15897 (scan_buffer, find_next_newline_no_quit)
15898 (find_before_next_newline, search_command, Freplace_match)
15899 (Fmatch_data): Make some `int' variables be EMACS_INT.
15901 * xdisp.c (display_count_lines): 3rd argument and return value now
15902 EMACS_INT. All callers changed.
15903 (pint2hrstr): Last argument is now EMACS_INT.
15905 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
15906 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
15907 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
15908 (decode_coding_utf_16, decode_coding_emacs_mule)
15909 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
15910 (decode_coding_ccl, decode_coding_charset)
15911 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
15912 (decode_coding_iso_2022, decode_coding_emacs_mule)
15913 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
15914 <char_offset, last_offset>: Declare EMACS_INT.
15915 (encode_coding_utf_8, encode_coding_utf_16)
15916 (encode_coding_emacs_mule, encode_invocation_designation)
15917 (encode_designation_at_bol, encode_coding_iso_2022)
15918 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
15919 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
15921 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
15922 (encode_invocation_designation): Last argument P_NCHARS is now
15924 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
15925 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
15927 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
15930 * ccl.c (Fccl_execute_on_string): Declare some variables
15933 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
15935 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
15937 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
15939 * process.c (Fformat_network_address): Doc fix.
15941 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
15943 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
15945 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
15947 * keyboard.c (read_char): Call Lisp function help-form-show,
15948 instead of using internal_with_output_to_temp_buffer.
15949 (Qhelp_form_show): New var.
15950 (syms_of_keyboard): Use DEFSYM macro.
15952 * print.c (internal_with_output_to_temp_buffer): Function deleted.

15956 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
15958 * process.c (Flist_processes): Remove to Lisp.
15959 (list_processes_1): Delete.
15961 2011-04-06 Eli Zaretskii <eliz@gnu.org>
15963 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
15965 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
15967 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
15969 Fix more problems found by GCC 4.6.0's static checks.
15971 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
15973 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
15975 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
15977 * xdisp.c (vmessage): Mark as a printf-like function.
15979 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
15981 * sound.c (sound_warning): Don't crash if arg contains a printf format.
15983 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
15984 printf-like functions.

15986 to system-supplied API.
15988 * eval.c (Fsignal): Remove excess argument to 'fatal'.
15990 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
15991 This avoids several warnings with gcc -Wstrict-overflow.
15992 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
15993 directly, rather than having caller test rule sign. This avoids
15994 some unnecessary tests.
15995 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
15996 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
15997 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
15999 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16000 (xfont_open): Avoid unnecessary tests.
16002 * composite.c (composition_gstring_put_cache): Use unsigned integer.
16004 * composite.h, composite.c (composition_gstring_put_cache):
16005 Use EMACS_INT, not int, for length.
16007 * composite.h (COMPOSITION_DECODE_REFS): New macro,
16008 breaking out part of COMPOSITION_DECODE_RULE.
16009 (COMPOSITION_DECODE_RULE): Use it.
16010 * composite.c (get_composition_id): Remove unused local vars,
16011 by using the new macro.
16013 * textprop.c (set_text_properties_1): Change while to do-while,
16014 since the condition is always true at first.
16016 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16017 (interval_deletion_adjustment): Return unsigned value.
16020 * process.c (list_processes_1, create_pty, read_process_output):
16021 (exec_sentinel): Remove vars that were set but not used.
16022 (create_pty): Remove unnecessary "volatile"s.
16023 (Fnetwork_interface_info): Avoid possibility of int overflow.

16025 (read_process_output): Simplify nbytes computation if buffered.
16027 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
16029 * syntax.c (scan_words): Remove var that was set but not used.
16030 (update_syntax_table): Use unsigned instead of int.
16032 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
16033 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
16034 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
16036 * print.c (print_error_message): Avoid int overflow.
16038 * font.c (font_list_entities): Redo for clarity,
16039 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
16041 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
16042 (font_score): Avoid potential overflow in diff calculation.
16044 * fns.c (substring_both): Remove var that is set but not used.
16045 (sxhash): Redo loop for clarity and to avoid wraparound warning.
16047 * eval.c (funcall_lambda): Rename local to avoid shadowing.
16049 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
16050 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
16051 can always succeed if overflow has undefined behavior.
16053 * search.c (boyer_moore, wordify): Remove vars set but not used.
16054 (wordify): Omit three unnecessary tests.
16056 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
16057 All callers changed. This avoids the need for an unused var.
16059 * casefiddle.c (casify_region): Remove var that is set but not used.
16061 * dired.c (file_name_completion): Remove var that is set but not used.
16063 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
16065 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16066 (Finsert_file_contents): Remove unnecessary code checking fd.
16068 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
16069 Check for integer overflow on size calculations.
16071 * buffer.c (Fprevious_overlay_change): Remove var that is set
16074 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16075 Remove vars that are set but not used.
16076 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16077 (timer_check_2): Mark vars as initialized.
16079 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16081 * image.c (lookup_image): Remove var that is set but not used.
16082 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16084 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16085 that are set but not used.
16087 * xfns.c (make_invisible_cursor): Don't return garbage
16088 if XCreateBitmapFromData fails (Bug#8410).
16090 * xselect.c (x_get_local_selection, x_handle_property_notify):
16091 Remove vars that are set but not used.
16093 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

16097 Remove var that is set but not used.
16098 (scroll_bar_windows_size): Now size_t, not int.
16099 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16100 Check for overflow.
16102 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16103 (map_tty_color) [!defined MSDOS]: Likewise.
16105 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16107 * coding.c: Remove vars that are set but not used.
16108 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

16115 that is set but not used.
16117 * print.c (print_object): Remove var that is set but not used.
16119 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16120 The gnulib version avoids calling malloc in the usual case,
16121 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16122 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16123 * filelock.c (current_lock_owner): Likewise.
16124 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16125 * sysdep.c: Include allocator.h, careadlinkat.h.
16126 (emacs_no_realloc_allocator): New static constant.
16127 (emacs_readlink): New function.
16128 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16129 ../lib/careadlinkat.h.
16131 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
16133 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

16155 do not dereference NULL upon failed strdup
16156 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16157 (ns_get_family): Likewise.
16159 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16161 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16163 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16165 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16168 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16170 Add lexical binding.
16172 * window.c (Ftemp_output_buffer_show): New fun.
16173 (Fsave_window_excursion):
16174 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.

16181 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16183 (syms_of_lread): Declare `lexical-binding'.
16185 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16187 * keyboard.c (eval_dyn): New fun.
16188 (menu_item_eval_property): Use it.
16190 * image.c (parse_image_spec): Use Ffunctionp.
16192 * fns.c (concat, mapcar1): Accept byte-code-functions.
16194 * eval.c (Fsetq): Handle lexical vars.
16195 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16196 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16197 (FletX, Flet): Obey lexical binding.
16198 (Fcommandp): Handle closures.
16199 (Feval): New `lexical' arg.
16200 (eval_sub): New function extracted from Feval. Use it almost
16201 everywhere where Feval was used. Look up vars in lexical env.
16203 (Ffunctionp): Move from subr.el.
16204 (Ffuncall): Handle closures.
16205 (apply_lambda): Remove `eval_flags'.
16206 (funcall_lambda): Handle closures and new byte-code-functions.
16207 (Fspecial_variable_p): New function.
16208 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16209 but without exporting it to Lisp.
16211 * doc.c (Fdocumentation, store_function_docstring):
16212 * data.c (Finteractive_form): Handle closures.
16214 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16217 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16219 (exec_byte_code): New function extracted from Fbyte_code to handle new
16220 calling convention for byte-code-functions. Add new byte-codes.
16222 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
16224 * alloc.c (Fmake_symbol): Init new `declared_special' field.
16226 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16228 * xdisp.c (redisplay_internal): Fix prototype.
16230 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16232 * xdisp.c (SCROLL_LIMIT): New macro.
16233 (try_scrolling): Use it when setting scroll_limit.
16234 Limit scrolling to 100 screen lines.
16235 (redisplay_window): Even when falling back on "recentering",
16236 position point in the window according to scroll-conservatively,
16237 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16239 (try_scrolling): When point is above the window, allow searching
16240 as far as scroll_max, or one screenful, to compute vertical
16241 distance from PT to the scroll margin position. This prevents
16242 try_scrolling from unnecessarily failing when
16243 scroll-conservatively is set to a value slightly larger than the
16244 window height. Clean up the case of PT below the margin at bottom
16245 of window: scroll_max can no longer be INT_MAX. When aggressive
16246 scrolling is in use, don't let point enter the opposite scroll
16247 margin as result of the scroll.
16248 (syms_of_xdisp) <scroll-conservatively>: Document the
16249 threshold of 100 lines for never-recentering scrolling.
16251 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

16256 (message_log_check_duplicate): Remove parameters `prev_bol' and
16257 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16258 (redisplay_internal): Remove parameter `preserve_echo_area',
16259 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16261 * indent.c (Fvertical_motion):
16262 * window.c (window_scroll_pixel_based, Frecenter):
16263 Don't pass `need_y_p' to `move_it_by_lines'.
16265 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16267 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16268 steal a few bits to be more compact.
16269 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16270 Remove unneeded casts.
16272 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16274 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16276 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16277 binding" message (bug#7967).
16279 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16281 Fix more problems found by GCC 4.6.0's static checks.
16283 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16284 Remove unused local var.
16286 * editfns.c (Fmessage_box): Remove unused local var.
16288 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16289 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16290 Omit unused local vars.
16291 * window.c (shrink_windows): Omit unused local var.
16292 * menu.c (digest_single_submenu): Omit unused local var.
16293 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16294 Omit unused local var.
16296 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16297 Don't assume string length fits in int.
16298 (keyremap_step, read_key_sequence): Use size_t for sizes.

16302 instead of alloca (Bug#8344).
16304 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16305 (Fbacktrace_frame): Don't assume nframes fits in int.
16307 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

16314 * cm.c (calccost): Turn while-do into do-while, for clarity.
16316 * keyboard.c (syms_of_keyboard): Use the same style as later
16317 in this function when indexing through an array. This also
16318 works around GCC bug 48267.
16320 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16322 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16324 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16325 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16327 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16328 This avoids undefined behavior on integer overflow, and is a bit
16329 more convenient anyway since it is compared to a size_t variable.
16331 Variadic C functions now count arguments with size_t, not int.
16332 This avoids an unnecessary limitation on 64-bit machines, which
16333 caused (substring ...) to crash on large vectors (Bug#8344).

16343 * fns.c (concat): Likewise.
16344 * frame.c (x_set_frame_parameters): Likewise.
16345 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16346 0 if not found, not -1. All callers changed.
16348 * alloc.c (garbage_collect): Don't assume stack size fits in int.
16349 (stack_copy_size): Now size_t, not int.
16350 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
16352 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
16354 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
16355 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

16371 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
16372 don't set the hook to nil, but remove the offending function instead.

16374 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
16375 Vcommand_hook_internal.

16378 (funcall_nil, funcall_not): New functions.
16379 (run_hook_with_args): Call each function through a `funcall' argument.

16518 * w32term.c (x_set_glyph_string_clipping):
16519 Don't pass uninitialized region to CombineRgn.
16521 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
16523 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.

16543 2011-03-23 Julien Danjou <julien@danjou.info>
16545 * term.c (Fsuspend_tty, Fresume_tty):
16546 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
16547 * window.c (temp_output_buffer_show):
16548 * insdel.c (signal_before_change):
16549 * frame.c (Fhandle_switch_frame):
16550 * fileio.c (Fdo_auto_save):
16551 * emacs.c (Fkill_emacs):
16552 * editfns.c (save_excursion_restore):
16553 * cmds.c (internal_self_insert):
16554 * callint.c (Fcall_interactively):
16555 * buffer.c (Fkill_all_local_variables):
16556 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
16558 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
16559 unconditionally since it does the check itself.
16561 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
16563 Fix more problems found by GCC 4.5.2's static checks.
16565 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16566 the first time through the loop, since we know p0 < p1 then.
16567 This also avoids a gcc -Wstrict-overflow warning.
16569 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16570 leading to a memory leak, possible in functions like
16571 load_charset_map_from_file that can allocate an unbounded number
16572 of objects (Bug#8318).
16574 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16575 that could (at least in theory) be that large.
16577 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16578 This is less likely to overflow, and avoids undefined behavior if
16579 overflow does occur. All callers changed. Use strtoul to scan
16580 for the unsigned long integer.
16581 (pint2hrstr): Simplify and tune code slightly.
16582 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
16584 * scroll.c (do_scrolling): Work around GCC bug 48228.
16585 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
16587 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
16588 This also avoids a warning with gcc -Wstrict-overflow.
16589 (validate_x_resource_name): Simplify count usage.
16590 This also avoids a warning with gcc -Wstrict-overflow.
16592 * fileio.c (Fcopy_file): Report error if fchown or fchmod
16595 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
16597 * process.c (Fmake_network_process): Use socklen_t, not int,
16598 where POSIX says socklen_t is required in portable programs.
16599 This fixes a porting bug on hosts like 64-bit HP-UX, where
16600 socklen_t is wider than int (Bug#8277).
16601 (Fmake_network_process, server_accept_connection):
16602 (wait_reading_process_output, read_process_output):
16605 * process.c: Rename or move locals to avoid shadowing.

16615 Make tparam.h and terminfo.c consistent.
16616 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
16617 Include tparam.h instead, since it declares them.
16618 * cm.h (PC): Remove extern decl; tparam.h now does this.
16619 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
16620 * terminfo.c: Include tparam.h, to check interfaces.
16621 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
16622 (tparam): Adjust signature to match interface in tparam.h;
16623 this removes some undefined behavior. Check that outstring and len
16624 are zero, which they always are with Emacs.
16625 * tparam.h (PC, BC, UP): New extern decls.
16627 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
16628 (xftfont_open): Rename locals to avoid shadowing.
16630 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
16631 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
16632 (OTF_TAG_SYM): Omit macro if not needed.

16640 * xml.c (make_dom): Now static.
16642 * composite.c (composition_compute_stop_pos): Rename local to
16644 (composition_reseat_it): Remove unused locals.
16645 (find_automatic_composition, composition_adjust_point): Likewise.
16646 (composition_update_it): Mark var as initialized.
16647 (find_automatic_composition): Mark vars as initialized,
16648 with a FIXME (Bug#8290).
16650 character.h: Rename locals to avoid shadowing.
16651 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
16652 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
16653 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
16654 (BUF_DEC_POS): Be more systematic about renaming local temporaries
16655 to avoid shadowing.
16657 * textprop.c (property_change_between_p): Remove; unused.
16659 * intervals.c (interval_start_pos): Now static.
16661 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

16664 Rename locals to avoid shadowing.
16666 * sound.c (wav_play, au_play, Fplay_sound_internal):
16667 Fix pointer signedness.
16668 (alsa_choose_format): Remove unused local var.
16669 (wav_play): Initialize a variable to 0, to prevent undefined
16670 behavior (Bug#8278).
16672 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
16674 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
16676 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
16677 clobbering (Bug#8298).
16678 * sysdep.c (sys_subshell): Likewise.
16679 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
16681 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
16682 This should get cleaned up, so that child_setup has the
16683 same signature on all platforms.
16685 * callproc.c (call_process_cleanup): Now static.
16686 (relocate_fd): Rename locals to avoid shadowing.
16688 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
16690 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
16691 not to be necessary, and produces flickering.
16693 2011-03-20 Glenn Morris <rgm@gnu.org>
16695 * config.in: Remove file.
16697 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
16699 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
16700 are now in src/globals.h.
16701 (syms_of_minibuf): Remove spurious & from previous change.
16703 2011-03-20 Leo Liu <sdl.web@gmail.com>
16705 * minibuf.c (completing-read-function): New variable.
16706 (completing-read-default): Rename from completing-read.
16707 (completing-read): Call completing-read-function.
16709 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16711 * xfaces.c (Fx_load_color_file):
16712 Read color file from absolute filename (bug#8250).
16714 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16716 * makefile.w32-in: Update dependencies.
16718 2011-03-17 Eli Zaretskii <eliz@gnu.org>
16720 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

16727 (sigchld_handler): Now static.
16729 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
16730 That way, the code declares only the vars that it needs.
16731 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
16732 * s/cygwin.h (PTY_ITERATION): Likewise.
16733 * s/darwin.h (PTY_ITERATION): Likewise.

16737 * process.c (allocate_pty): Don't declare stb unless it's needed.
16739 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
16740 (CONSTANTLIM): Remove; unused.
16741 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
16742 Define only if needed.
16744 * unexelf.c (unexec): Name an expression,
16745 to avoid gcc -Wbad-function-cast warning.
16746 Use a different way to cause a compilation error if anyone uses
16747 n rather than nn, a way that does not involve shadowing.
16748 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
16750 * deps.mk (unexalpha.o): Remove; unused.
16752 New file unexec.h, the (simple) interface for unexec (Bug#8267).
16753 * unexec.h: New file.
16754 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
16755 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
16756 Depend on unexec.h.
16757 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
16758 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
16759 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
16760 Change as necessary to match prototype in unexec.h.
16762 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
16764 (back_comment, skip_chars): Mark vars as initialized.
16766 * character.h (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS):

16778 instead of using an uninitialized var.
16779 (font_sort_entities): Mark var as initialized.
16781 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
16783 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

16795 * floatfns.c (domain_error2): Define only if needed.
16796 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
16798 * alloc.c (mark_backtrace): Move decl from here ...
16799 * lisp.h: ... to here, so that it can be checked.
16801 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
16802 (Fdefvar): Rewrite so as not to use empty "else".
16803 (lisp_indirect_variable): Name an expression,
16804 to avoid gcc -Wbad-function-cast warning.
16805 (Fdefvar): Rename locals to avoid shadowing.
16807 * callint.c (quotify_arg, quotify_args): Now static.
16808 (Fcall_interactively): Rename locals to avoid shadowing.
16809 Use const pointer when appropriate.
16811 * lisp.h (get_system_name, get_operating_system_release):
16812 Move decls here, to check interfaces.
16813 * process.c (get_operating_system_release): Move decl to lisp.h.
16814 * xrdb.c (get_system_name): Likewise.
16815 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
16816 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
16817 some of which prompt warnings from gcc -Wbad-function-cast.
16818 (Fformat_time_string, Fencode_time, Finsert_char):
16819 (Ftranslate_region_internal, Fformat):
16820 Rename or remove local vars to avoid shadowing.
16821 (Ftranslate_region_internal): Mark var as initialized.
16823 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
16826 * lisp.h (eassert): Check that the argument compiles, even if
16827 ENABLE_CHECKING is not defined.
16829 * data.c (Findirect_variable): Name an expression, to avoid
16830 gcc -Wbad-function-cast warning.
16831 (default_value, arithcompare, arith_driver, arith_error): Now static.
16832 (store_symval_forwarding): Rename local to avoid shadowing.
16833 (Fmake_variable_buffer_local, Fmake_local_variable):

16838 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
16839 Rename locals to avoid shadowing.
16840 (mark_stack): Move local variables into the #ifdef region where
16842 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
16843 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
16845 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
16846 (GC_STRING_CHARS): Remove; not used.
16847 (Fmemory_limit): Cast sbrk's returned value to char *.
16849 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
16850 avoids undefined behavior in theory.
16852 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
16854 Use functions, not macros, for up- and down-casing (Bug#8254).
16855 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16856 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
16857 to use the following functions instead of these macros.
16858 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
16859 EMACS_INT, since callers assume the returned value fits in int.
16860 (upcase1): Likewise, for UPCASE_TABLE.
16861 (uppercasep, lowercasep, upcase): New static inline functions.
16862 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
16863 the race-condition problem in the old DOWNCASE.
16865 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
16866 Rename locals to avoid shadowing.
16867 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
16868 (regex_compile, re_search_2, re_match_2_internal):
16869 Remove unused local vars.
16870 (FREE_VAR): Rewrite so as not to use empty "else",
16871 which gcc can warn about.
16872 (regex_compile, re_match_2_internal): Mark locals as initialized.
16873 (RETALLOC_IF): Define only if needed.
16874 (WORDCHAR_P): Likewise. This one is never needed, but is used
16875 only in a comment talking about a compiler bug, so put inside
16876 the #if 0 of that comment.
16877 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
16878 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
16881 * search.c (boyer_moore): Rename locals to avoid shadowing.
16882 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
16883 (PREV_CHAR_BOUNDARY): Likewise.
16885 * search.c (simple_search): Remove unused var.
16887 * dired.c (compile_pattern): Move decl from here ...

16889 (struct re_registers): New forward decl.
16891 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
16893 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
16895 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
16896 Rename locals to avoid shadowing.
16897 (Fvertical_motion): Mark locals as initialized.
16899 * casefiddle.c (casify_object, casify_region): Now static.
16900 (casify_region): Mark local as initialized.
16902 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
16904 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
16905 New macros, so that the caller can use some names other than
16906 gcpro1, gcpro2, etc.
16907 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
16909 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
16910 argument, for consistency with GCPRO2_VAR, etc: it is now the
16911 prefix of the variable, not the variable itself. All uses
16913 * dired.c (directory_files_internal, file_name_completion):
16914 Rename locals to avoid shadowing.
16916 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
16917 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
16918 dired.c's scmp function, had undefined behavior.
16919 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16920 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
16921 * buffer.h: ... to here, because these macros use current_buffer,
16922 and the new implementation with inline functions needs to have
16923 current_buffer in scope now, rather than later when the macros
16925 (downcase, upcase1): New static inline functions.
16926 (DOWNCASE, UPCASE1): Reimplement using these functions.
16927 This avoids undefined behavior in expressions like
16928 DOWNCASE (x) == DOWNCASE (y), which previously suffered
16929 from race conditions in accessing the global variables
16930 case_temp1 and case_temp2.
16931 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
16932 * lisp.h (case_temp1, case_temp2): Remove their decls.
16933 * character.h (ASCII_CHAR_P): Move from here ...
16934 * lisp.h: ... to here, so that the inline functions mentioned
16935 above can use them.
16937 * dired.c (directory_files_internal_unwind): Now static.
16939 * fileio.c (file_name_as_directory, directory_file_name):
16940 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
16942 (file_name_as_directory): Use const pointers when appropriate.
16943 (Fexpand_file_name): Likewise. In particular, newdir might
16944 point at constant storage, so make it a const pointer.
16945 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
16946 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
16948 (Fset_file_times, Finsert_file_contents, auto_save_error):
16949 Rename locals to avoid shadowing.
16951 * minibuf.c (choose_minibuf_frame_1): Now static.
16952 (Ftry_completion, Fall_completions): Rename or remove locals
16953 to avoid shadowing.
16955 * marker.c (bytepos_to_charpos): Remove; unused.
16957 * lisp.h (verify_bytepos, count_markers): New decls,
16958 so that gcc does not warn that these functions aren't declared.
16960 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
16961 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
16962 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
16963 (copy_text): Remove unused local var.
16965 * filelock.c (within_one_second): Now static.
16966 (lock_file_1): Rename local to avoid shadowing.
16968 * buffer.c (fix_overlays_before): Mark locals as initialized.
