1 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4 or that fprintf is async-signal-safe. POSIX doesn't require
7 2012-09-22 Chong Yidong <cyd@gnu.org>
9 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
12 2012-09-22 Kenichi Handa <handa@gnu.org>
14 * composite.c (composition_reseat_it): Handle the case that a
15 grapheme cluster is not covered by a single font (Bug#12352).
17 2012-09-21 Chong Yidong <cyd@gnu.org>
19 * image.c (define_image_type): Avoid adding duplicate types to
20 image_types (Bug#12463). Suggested by Jörg Walter.
22 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
24 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
25 (print_load_command_name): Add case LC_DATA_IN_CODE.
26 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
28 2012-09-21 Glenn Morris <rgm@gnu.org>
30 * eval.c (Frun_hook_with_args_until_success)
31 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
33 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
35 * fileio.c (Ffile_selinux_context): Only call freecon when
36 lgetfilecon succeeded.
37 (Fset_file_selinux_context): Likewise. (Bug#12444)
39 2012-09-21 Eli Zaretskii <eliz@gnu.org>
41 * xdisp.c (try_window_reusing_current_matrix): Under bidi
42 reordering, locate the cursor by calling set_cursor_from_row; if
43 that fails, clear the desired glyph matrix before returning a
44 failure indication to the caller. Fixes leaving garbled display
45 when fast scrolling with a down-key. (Bug#12403)
46 (compute_stop_pos_backwards): Fix a typo that caused crashes while
47 scrolling through multibyte text.
49 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
51 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
52 calling mark_vectorlike since that's the one that marks the window.
53 (mark_discard_killed_buffers): Mark the final cdr.
54 * window.h (struct window): Move prev/next_buffers to the
56 * window.c (make_window): Initialize prev/next_buffers manually.
58 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
60 Omit unused arg EXPECTED from socket hooks.
61 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
62 * nsterm.m (ns_term_init):
63 * termhooks.h (struct terminal.read_socket_hook):
64 * w32inevt.c (w32_console_read_socket):
65 * w32term.c (w32_read_socket):
66 * xterm.c (XTread_socket):
67 Omit unused arg EXPECTED. All callers changed.
68 (store_user_signal_events): Return void, not int, since callers no
69 longer care about the return value. All uses changed.
71 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
73 * w32gui.h (XParseGeometry): Do not declare.
75 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
77 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
78 Ignore 'expected'. See Eli Zaretskii in
79 <http://bugs.gnu.org/12471#8> (last line).
81 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
82 (XParseGeometry): Now static. Substitute extremal values for
83 values that are out of range.
85 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
87 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
89 * nsfns.m (XParseGeometry): Remove.
90 (Fx_create_frame): Call x_set_offset to correctly interpret
93 * frame.c (read_integer, XParseGeometry): Moved from w32xfns.c.
94 (Fx_parse_geometry): If there is a space in string, call
95 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
97 2012-09-17 Eli Zaretskii <eliz@gnu.org>
99 * search.c (scan_buffer): Use character positions in calls to
100 region_cache_forward and region_cache_backward, not byte
101 positions. (Bug#12196)
103 * w32term.c (w32_read_socket): Set pending_signals to 1, like
104 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
106 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
107 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
108 emacs_blocked_malloc, now deleted.
110 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
112 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
113 The workaround was for improving performance on Solaris 2.4, but
114 is getting in the way now. Emacs will still work if someone is
115 still running Solaris 2.4 in a museum somewhere; Sun dropped
116 support for Solaris 2.4 in 2003.
117 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
118 * process.c (create_process) [HAVE_WORKING_VFORK]:
119 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
120 since Emacs no longer uses vfork on that platform.
122 2012-09-17 Glenn Morris <rgm@gnu.org>
124 * emacs.c: Use COPYRIGHT.
126 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
128 Remove configure's --without-sync-input option (Bug#12450).
129 When auditing signal-handling in preparation for cleaning it up,
130 I found that SYNC_INPUT has race conditions and would be a real
131 pain to fix. Since it's an undocumented and deprecated
132 configure-time option, now seems like a good time to remove it.
133 Also see <http://bugs.gnu.org/11080#16>.
134 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
135 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
136 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
138 (check_depth) [XMALLOC_OVERRUN_CHECK]:
139 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
140 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
141 (dont_register_blocks, bytes_used_when_reconsidered)
142 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
143 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
144 [!SYSTEM_MALLOC && !SYNC_INPUT]:
145 Remove. All uses removed.
146 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
147 implementation, one that depends on whether the new macro
148 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
150 * atimer.c (run_timers, handle_alarm_signal):
151 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
152 (handle_async_input, process_pending_signals)
153 (handle_input_available_signal, init_keyboard):
154 * nsterm.m (ns_read_socket):
155 * process.c (wait_reading_process_output):
156 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
157 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
159 * xterm.c (XTread_socket):
161 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
162 * eval.c (handling_signal): Remove. All uses removed.
163 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
164 All uses replaced with the SYNC_INPUT version.
165 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
167 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
170 * font.c (Ffont_shape_gstring): Remove unused local.
172 2012-09-16 Glenn Morris <rgm@gnu.org>
174 * Makefile.in (clean): No longer run nextstep's clean.
176 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
178 (ns-app): Move here from ns.mk, and simplify.
179 (clean): Simplify nextstep entry.
180 * ns.mk: Remove file.
182 2012-09-17 Kenichi Handa <handa@gnu.org>
184 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
185 not covert the last few charactes.
187 2012-09-16 Kenichi Handa <handa@gnu.org>
189 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
190 here, but just check the validity of glyphs in the glyph-string.
192 2012-09-16 Martin Rudalics <rudalics@gmx.at>
194 * window.c (Fwindow_parameter, Fset_window_parameter): Accept
195 any window as argument (Bug#12452).
197 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
199 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
200 to ns_term_init to avoid memory leak.
202 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
203 explicit retain/release.
204 (ns_term_init): Only allow one display. Initialize outerpool and
207 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
209 Port _setjmp fix to POSIXish hosts as well as Microsoft.
210 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
211 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
212 the Microsoft problem in a different way, by altering ../nt/config.nt.
214 2012-09-15 Eli Zaretskii <eliz@gnu.org>
229 * w16select.c: Remove inclusion of setjmp.h, as it is now included
230 by lisp.h. This completes removal of setjmp.h inclusion
231 erroneously announced in the previous commit. (Bug#12446)
233 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
236 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
237 not defined as a macro. The latter happens on MS-Windows.
240 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
242 Port better to POSIX hosts lacking _setjmp (Bug#12446).
243 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
244 Some instances of '#include <setjmp.h>' removed, if the
245 only reason for the instance was because "lisp.h" was included.
246 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
247 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
248 and _longjmp with the new symbols. Emacs already uses _setjmp if
249 available, so this change affects only POSIXish hosts that have
250 sigsetjmp but not _setjmp, such as some versions of Solaris and
251 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
252 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
253 (png_load_body) [HAVE_PNG]:
254 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
255 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
256 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
257 since PNG requires jmp_buf. This is the only exception to the
258 general rule that we now use sys_setjmp and sys_longjmp.
259 This exception is OK since this code does not change the signal
260 mask or longjmp out of a signal handler.
262 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
264 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
265 Include "syssignal.h", for 'main_thread'.
267 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
269 Avoid out-of-range marker position (Bug#12426).
270 * insdel.c (replace_range, replace_range_2): Adjust
271 markers before overlays, as suggested by comments.
272 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
273 Remove redundant check before calling offset_intervals.
275 2012-09-14 Martin Rudalics <rudalics@gmx.at>
277 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
278 current buffer (Bug#12387).
280 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
282 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
284 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
286 Use a more backwards-compatible timer format (Bug#12430).
287 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
288 vector element, not from the 4th, since PSECS is now at the end.
289 (Fcurrent_idle_time): Doc fix.
291 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
293 Function to mark objects and remove killed buffers at once.
294 * alloc.c (discard_killed_buffers): Rename to ...
295 (mark_discard_killed buffers) ... new name. Add marking
296 of remaining objects. Fix comment. Adjust users.
297 (mark_object): Do not touch frame buffer lists here.
298 * frame.c (delete_frame): Reset frame buffer lists here.
300 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
302 Better workaround for GNOME bug when --enable-gcc-warnings.
303 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
304 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
305 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
307 Simplify SIGIO usage (Bug#12408).
308 The code that dealt with SIGIO was crufty and confusing, e.g., it
309 played tricks like "#undef SIGIO" but these tricks were not used
310 consistently. Simplify mostly by not #undeffing standard symbols,
311 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
312 or not as we please) rather than "defined SIGIO" (standard symbol
313 that we probably shouldn't #undef).
314 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
315 Modules that need it can include it.
316 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
317 * dispextern.h (ignore_sigio): New decl.
318 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
319 unconditionally, since it's now a no-op if !USABLE_SIGIO.
320 * emacs.c (shut_down_emacs):
321 * keyboard.c (kbd_buffer_store_event_hold):
322 Use ignore_sigio rather than invoking 'signal' directly.
323 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
325 (FIONREAD, SIGIO): Do not #undef.
326 (tty_read_avail_input): Use #error rather than a syntax error.
327 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
328 for I_PIPE, used by SETUP_SLAVE_PTY.
329 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
330 * sysdep.c (croak): Remove; no longer needed. This bit of
331 temporary code, with Fred N. Fish's comment that it's temporary,
332 has been in Emacs since at least 1992!
333 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
334 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
335 * syssignal.h (croak): Remove decl.
336 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
337 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
338 now that we're termios-only.
339 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
340 * term.c (dissociate_if_controlling_tty): Use #error rather than
343 Work around GCC and GNOME bugs when --enable-gcc-warnings.
344 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
345 to work around GNOME bug 683906.
346 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
347 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
348 This works around GCC bug 54561.
350 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
352 More fixes for 'volatile' and setjmp/longjmp.
353 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
354 * image.c (struct png_load_context) [HAVE_PNG]: New type.
355 (png_load_body) [HAVE_PNG]:
356 (jpeg_load_body) [HAVE_JPEG]:
357 New function, with most of the old parent function's body.
358 (png_load) [HAVE_PNG]:
359 (jpeg_load) [HAVE_JPEG]:
360 Invoke the new function, to avoid longjmp munging our locals.
361 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
362 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
363 longjmp is passed 2, as the C standard doesn't guarantee this.
364 Instead, store the failure code into mgr->failure_code.
366 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
368 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
369 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
370 (syms_of_keyboard): Remove support for unread-command-char.
372 2012-09-12 Eli Zaretskii <eliz@gnu.org>
374 * w32proc.c (sys_kill): If PID is our process ID and the signal is
375 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
376 violation. (Bug#12426)
378 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
380 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
382 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
384 * eval.c: Add `inhibit-debugger'.
385 (Qinhibit_debugger): New symbol.
386 (call_debugger): Bind it instead of Qdebug_on_error.
387 (maybe_call_debugger): Test Vinhibit_debugger.
388 (syms_of_eval): Define inhibit-debugger.
389 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
390 (syms_of_xdisp): Remove inhibit-debug-on-message.
392 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
394 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
395 If a nonvolatile local variable is written before a _longjmp to
396 the frame containing the variable, and is read after the _longjmp,
397 the value read is indeterminate. Some local variables of type
398 'struct handler' and 'struct catchtag' are used in this way, so
399 mark each of their slots as volatile if the slot can be set before
400 _longjmp and read afterwards.
401 * lisp.h (struct handler): var and chosen_clause are now volatile.
402 (struct catchtag): val, next, and pdlcount are now volatile.
404 * bidi.c (bidi_push_it, bidi_pop_it):
405 * fns.c (copy_hash_table):
406 * image.c (define_image_type):
407 * keyboard.c (kbd_buffer_store_event_hold):
408 * process.c (Fprocess_send_eof):
409 * xfaces.c (x_create_gc) [HAVE_NS]:
410 * xgselect.c (xg_select):
411 Prefer assignment to memcpy when either will do.
413 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
414 Use pointer-to-a-pointer to simplify and avoid a NILP check each
415 time an item is removed. No need to mark this function 'inline';
416 the compiler knows better than we do.
418 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
420 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
421 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
422 to change_frame_size (Bug#12388).
423 (windowDidResize:): Pass YES to updateFrameSize.
425 * nsterm.h: Add delay parameter to updateFrameSize.
427 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
429 Discard killed buffers from deleted window and frame objects.
430 This reduces an amount of references to killed buffers and
431 helps GC to reclaim them faster.
432 * alloc.c (discard_killed_buffers): New function.
433 (mark_object): Use it for deleted windows and frames.
434 (mark_object): If symbol's value is set up for a killed buffer
435 or deleted frame, restore it's global binding.
436 * data.c (swap_in_global_binding): Add GC notice.
437 (swap_in_symval_forwarding): Use convenient set_blv_where.
438 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
439 * window.h: ... to here.
441 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
443 Convenient macro to check whether the buffer is live.
444 * buffer.h (BUFFER_LIVE_P): New macro.
445 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
446 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
448 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
450 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
451 composition cases (Bug#12364).
453 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
454 overhang of succeeding glyphs overlapping box cursor.
456 * w32term.c (x_draw_glyph_string): Likewise.
458 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
460 Simplify, document, and port floating-point (Bug#12381).
461 The porting part of this patch fixes bugs on non-IEEE platforms
462 with frexp, ldexp, logb.
463 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
465 * floatfns.c: Simplify discussion of functions that Emacs doesn't
466 support, by removing commented-out code and briefly listing the
467 C89 functions excluded. The commented-out stuff was confusing
468 maintenance, e.g., we thought we needed cbrt but it was commented out.
469 (logb): Remove decl; no longer needed.
470 (isfinite): New macro, if not already supplied.
471 (isnan): Don't replace any existing macro.
472 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
473 are present on all C89 platforms.
474 (Ffrexp): Do not special-case zero, as frexp does the right thing
476 (Flogb): Do not use logb, as it doesn't have the desired meaning
477 on hosts that use non-base-2 floating point. Instead, stick with
478 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
479 frexp, to avoid getting an unspecified result.
481 * xdisp.c (Qinhibit_debug_on_message): Now static.
483 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
485 * nsterm.m (ns_update_begin): Set clip path to whole view by using
486 NSBezierPath (Bug#12131).
488 2012-09-10 Chong Yidong <cyd@gnu.org>
490 * fns.c (Fdelq, Fdelete): Doc fix.
492 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
494 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
495 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
497 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
499 * lisp.h (make_lisp_ptr): New macro to replace XSET.
500 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
503 2012-09-09 Eli Zaretskii <eliz@gnu.org>
505 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
506 left fringe if the window has a left margin. This avoids leaving
507 traces of the cursor because its leftmost pixel is not drawn over.
509 * dispnew.c (update_window_line): When the left margin area of a
510 screen line is updated, set the redraw_fringe_bitmaps_p flag of
511 that screen line. (Bug#12277)
513 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
515 Assume C89 or later for math functions (Bug#12381).
516 This simplifies the code, and makes it a bit smaller and faster,
517 and (most important) makes it easier to clean up signal handling
518 since we can stop worring about floating-point exceptions in
519 library code. That was a problem before C89, but the problem
520 went away many years ago on all practical Emacs targets.
521 * data.c, image.c, lread.c, print.c:
522 Don't include <math.h>; no longer needed.
523 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
524 might be autoconfigured, as that never happens.
526 * doprnt.c (DBL_MAX_10_EXP):
528 Remove. C89 or later always defines these.
529 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
530 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
531 (arith_error, domain_error, domain_error2):
532 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
533 no longer needed -- we simply return what C returns. All uses removed.
534 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
536 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
537 Remove. All uses expanded, as these macros are no longer used
538 more than once and are now more trouble than they're worth.
539 (Ftan): Use tan, not sin / cos.
540 (Flogb): Assume C89 frexp.
541 (fmod_float): Assume C89 fmod.
542 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
543 (init_floatfns): Remove. All uses removed.
545 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
547 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
548 compositeToPoint for OSX < 10.6 (Bug#12390).
550 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
552 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
553 This produces more-accurate results.
555 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
557 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
560 2012-09-08 Chong Yidong <cyd@gnu.org>
562 * syntax.c (Fstring_to_syntax): Doc fix.
564 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
566 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
567 in the internal border.
568 (x_set_window_size): Remove static variables and their usage.
569 (ns_redraw_scroll_bars): Fix NSTRACE arg.
570 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
571 fringe/internal border adjustment (Bug#11052).
572 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
573 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
574 (ns_fix_rect_ibw): Remove.
575 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
576 (ns_dumpglyphs_box_or_relief): Ditto.
577 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
579 (ns_dumpglyphs_image): Ditto.
580 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
582 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
583 their usage. Add fringe_extended_p and its use as in other terms.
584 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
585 scroll bar was removed.
586 (updateFrameSize): New function.
587 (windowDidResize): Move code to updateFrameSize and call it.
589 * nsterm.h (EmacsView): Add updateFrameSize.
591 2012-09-07 Chong Yidong <cyd@gnu.org>
593 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
595 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
597 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
599 More signal-handler cleanup (Bug#12327).
600 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
601 Problem introduced when merging patches. Noted by Eli Zaretskii in
602 <http://bugs.gnu.org/12327#67>.
603 * floatfns.c: Comment fix.
604 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
605 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
606 and anyway the declaration is harmless even if SIGDANGER is not defined.
607 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
608 defined BROKEN_FIONREAD). systty.h formerly did this, but other
609 source files not surprisingly expected syssignal.h to define, or
610 not define, SIGIO, and it's cleaner to do it that way, for consistency.
611 Include <sys/ioctl.h>, for FIONREAD.
612 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
613 This eliminates a problem whereby other files mysteriously had
614 to include "syssignal.h" before including "systty.h" if they
615 wanted to use "#ifdef SIGIO".
617 2012-09-07 Eli Zaretskii <eliz@gnu.org>
619 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
621 * w32.c (sigemptyset): Empty the set.
622 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
624 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
626 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
628 * alloc.c (mark_buffer): Revert unsafe marking optimization.
629 (mark_object): Likewise for frame objects.
631 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
633 * syssignal.h (handle_on_main_thread): Always declare,
634 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
635 This ports to platforms without HAVE_PTHREAD.
637 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
639 Signal-handler cleanup (Bug#12327).
640 Emacs's signal handlers were written in the old 4.2BSD style with
641 sigblock and sigmask and so forth, and this led to some
642 inefficiencies and confusion. Rewrite these to use
643 pthread_sigmask etc. without copying signal sets around. Also,
644 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
645 'signal', and instead use functions that do not attempt to take
646 over the system name space. This patch causes Emacs's text
647 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
648 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
649 Do not include <signal.h> or "syssignal.h", as these
650 modules do not use signals.
651 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
652 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
653 Do not include <signal.h>, as "syssignal.h" does that for us now.
654 * atimer.c (sigmask_atimers): New function.
655 (block_atimers, unblock_atimers): New functions,
656 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
658 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
659 no longer needed here.
660 * emacs.c (main): Inspect existing signal handler with sigaction,
661 so that there's no need to block and unblock SIGHUP.
662 * sysdep.c (struct save_signal): New member 'action', replacing
663 old member 'handler'.
664 (save_signal_handlers, restore_signal_handlers):
665 Use sigaction instead of 'signal' to save and restore.
666 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
667 New function. All users of 'signal' modified to use set_sighandler
668 if they're writeonly, and to use sys_signal if they're read+write.
669 (emacs_sigaction_init, forwarded_signal): New functions.
670 (sys_signal): Remove. All uses replaced by calls to sigaction
671 and emacs_sigaction_init, or by direct calls to 'signal'.
672 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
673 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
674 all uses replaced by pthread_sigmask etc. calls.
675 * syssignal.h: Include <signal.h>.
676 (emacs_sigaction_init, forwarded_signal): New decls.
677 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
678 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
679 (sigmask, sys_sigmask): Remove; no longer needed.
680 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
681 (sigblock, sigunblock, sigfree):
682 (sigsetmask) [!defined sigsetmask]:
683 Remove. All uses replaced by pthread_sigmask.
684 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
685 no longer need to be replaced, and its typical old uses
686 are now done via emacs_sigaction_init and sigaction.
687 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
688 (sys_sigdel): Remove; unused.
689 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
691 2012-09-06 Eli Zaretskii <eliz@gnu.org>
693 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
694 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
696 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
698 Explicitly mark buffer_defaults and buffer_local_symbols.
699 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
700 mark_local_symbols here.
701 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
702 since special buffers aren't marked here any more.
703 (allocate_buffer): Chain new buffer with all_buffers here...
704 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
706 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
707 (syms_of_buffer): Remove staticpro of the above.
708 (init_buffer_once): Set names for buffer_defaults and
709 buffer_local_symbols.
711 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
713 Use bool for booleans in font-related modules.
714 * font.c (font_intern_prop, font_style_to_value)
715 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
716 (generate_otf_features, font_check_otf_features, font_check_otf)
717 (font_match_p, font_list_entities, font_at):
718 * fontset.c (fontset_id_valid_p, reorder_font_vector
719 (fontset_find_font, Fset_fontset_font)
720 (face_suitable_for_char_p) [0]:
721 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
722 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
723 (m17n_flt_initialized, ftfont_shape_by_flt):
724 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
725 * nsfont.m (nsfont_draw):
726 * w32font.c (w32font_draw):
727 * w32term.c (x_draw_glyphless_glyph_string_foreground):
728 Use bool for booleans.
729 * font.h: Adjust to above API changes.
730 (struct font, struct font_driver, struct font_driver_list):
731 Use bool for booleans.
732 (struct font): Remove useless member encoding_type.
734 * fontset.c, xftfont.c: Omit unnecessary static decls.
736 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
738 * alloc.c (mark_object): Revert window marking code
739 since it's unsafe for the Fset_window_configuration.
741 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
743 Fix race conditions with signal handlers and errno (Bug#12327).
744 Be more systematic about preserving errno whenever a signal
745 handler returns, even if it's not in the main thread. Do this by
746 renaming signal handlers to distinguish between signal delivery
747 and signal handling. All uses changed.
748 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
749 * data.c (deliver_arith_signal): Rename from arith_error.
750 * dispnew.c (deliver_window_change_signal): Rename from
751 window_change_signal.
752 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
753 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
754 * keyboard.c (deliver_input_available_signal): Rename from
755 input_available_signal.
756 (deliver_user_signal): Rename from handle_user_signal.
757 (deliver_interrupt_signal): Rename from interrupt_signal.
758 * process.c (deliver_pipe_signal): Rename from send_process_trap.
759 (deliver_child_signal): Rename from sigchld_handler.
760 * atimer.c (handle_alarm_signal):
761 * data.c (handle_arith_signal):
762 * dispnew.c (handle_window_change_signal):
763 * emacs.c (handle_fatal_signal, handle_danger_signal):
764 * keyboard.c (handle_input_available_signal):
765 * keyboard.c (handle_user_signal, handle_interrupt_signal):
766 * process.c (handle_pipe_signal, handle_child_signal):
767 New functions, with the actual signal-handling code taken from the
768 original respective signal handlers, sans the sporadic attempts to
769 preserve errno, since that's now done by handle_on_main_thread.
770 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
771 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
772 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
774 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
775 Move initialization of main_thread to sysdep.c's init_signals.
776 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
777 our usage, and simplifies the mainline code.
778 (record_child_status_change): New static function, as a helper
779 for handle_child_signal, and with most of the old child handler's
781 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
782 (handle_child_signal): Use the above.
783 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
784 Moved here from emacs.c.
785 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
786 code moved here from emacs.c's main function.
787 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
788 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
789 lets callers save and restore errno properly.
791 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
793 Remove redundant or unused things here and there.
794 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
795 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
796 * editfns.c (Fcompare_buffer_substrings): Likewise.
797 * frame.h (struct terminal, struct font_driver_list):
798 Remove redundant declarations.
799 * window.h (Qleft, Qright): Likewise.
801 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
803 Do not mark objects from deleted buffers, windows and frames.
804 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
805 (mark_object): Likewise for windows and frames.
807 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
809 * alloc.c (valid_lisp_object_p): Treat killed buffers,
810 buffer_defaults and buffer_local_symbols as valid objects.
811 Return special value to denote them.
813 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
815 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
816 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
817 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
818 (file_name_absolute_p, Fsubstitute_in_file_name):
819 (check_executable, check_writable, Ffile_accessible_directory_p)
820 (Fset_file_selinux_context, Fdefault_file_modes)
821 (Finsert_file_contents, choose_write_coding_system)
822 (Fwrite_region, build_annotations, a_write, e_write)
824 * filelock.c (boot_time_initialized, get_boot_time)
825 (get_boot_time_1, lock_file_1, within_one_second):
826 * floatfns.c (in_float):
827 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
828 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
829 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
830 * lisp.h (struct Lisp_Hash_Table.cmpfn):
831 * window.c (compare_window_configurations):
832 Use bool for booleans.
833 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
834 (Fdefault_file_modes): Now mode_t, not int, for modes.
835 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
836 (internal_delete_file): Now returns void, not a (boolean) int,
837 since nobody was looking at the return value.
838 * lisp.h, window.h: Adjust to above API changes.
840 * xdisp.c (set_message): Simplify and reindent last change.
842 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
844 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
846 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
848 * eval.c (call_debugger): Make the function non-static so that we
849 can call it from set_message.
851 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
852 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
854 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
856 Give more-useful info on a fatal error (Bug#12328).
857 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
858 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
859 of doing the work ourselves.
860 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
862 (fatal_error_backtrace): New function, taken from the guts
863 of the old fatal_error_signal, but with a new option to output
865 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
866 info about the signal than just its number.
867 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
868 * sysdep.c: Include <execinfo.h>
869 (emacs_backtrace): New function, taken partly from the previous
870 code of the 'die' function.
871 (emacs_abort): Call fatal_error_backtrace rather than abort.
873 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
875 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
876 eager (load-time) macro-expansion.
877 * lisp.mk (lisp): Add macroexp.
879 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
881 Simplify redefinition of 'abort' (Bug#12316).
882 Do not try to redefine the 'abort' function. Instead, redo
883 the code so that it calls 'emacs_abort' rather than 'abort'.
884 This removes the need for the NO_ABORT configure-time macro
885 and makes it easier to change the abort code to do a backtrace.
886 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
887 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
888 Remove; sysdep.c's emacs_abort now takes its place.
889 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
890 'abort' changed to use 'emacs_abort'.
891 * msdos.c (dos_abort) [defined abort]: Remove; not used.
892 (abort) [!defined abort]: Rename to ...
893 (emacs_abort): ... new name.
894 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
895 the place of the old 'abort' in emacs.c.
896 * w32.c, w32fns.c (abort): Do not #undef.
897 * w32.c (emacs_abort): Rename from w32_abort.
899 2012-09-04 Eli Zaretskii <eliz@gnu.org>
901 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
902 offsets[j].dv, since the y axis of the screen coordinates points
903 down, while the y axis of the font definition coordinates points
904 up. This fixes display of Arabic diacritics such as KASRA and
905 KASRATAN. (Bug#11860)
907 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
909 Be more systematic about _setjmp vs setjmp.
910 * alloc.c (test_setjmp, mark_stack):
911 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
912 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
913 (png_load, my_error_exit, jpeg_load):
914 * process.c (send_process_trap, send_process):
915 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
916 The underscored versions are up to 30x faster on some hosts.
917 Formerly, the code used setjmp+longjmp sometimes and
918 _setjmp+_longjmp at other times, with no particular reason to
919 prefer setjmp+longjmp.
921 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
923 Fix minor problem found by static checking.
924 * buffer.c (Fdelete_all_overlays): Return nil.
926 2012-09-03 Martin Rudalics <rudalics@gmx.at>
928 * buffer.c (Fdelete_all_overlays): New function.
930 2012-09-03 Chong Yidong <cyd@gnu.org>
932 * gtkutil.c: Add extern decl for Qxft.
934 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

1053 offset adjustment values separately for each cluster. (Bug#11860)
1055 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1056 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1057 about implicit conversions from integer to pointer.
1059 2012-09-01 Daniel Colascione <dancol@dancol.org>

1115 window system declarations.
1117 * frame.h: Move common functions here: set_frame_menubar,
1118 x_set_window_size, x_sync, x_get_focus_frame,
1119 x_set_mouse_position, x_set_mouse_pixel_position,
1120 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

1206 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
1207 Add window_closed and button_values. Add void as return value for
1208 add(Button|String|Split). addButton takes int instead of Lisp_Object.
1209 Add process_dialog as new member.

1388 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
1389 * window.c (Qwindow_valid_p, decode_valid_window):
1390 Now static, not extern.
1391 * data.c (Qinterval): Remove; unused.
1392 (syms_of_data): Do not define 'interval'.
1393 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
1394 * window.h (decode_valid_window):
1397 * character.c, charset.c, chartab.c: Use bool for booleans.
1398 * character.c (lisp_string_width, string_count_byte8)
1399 (string_escape_byte8):
1400 * charset.c (charset_map_loaded, load_charset_map, read_hex):
1401 (load_charset_map_from_file, map_charset_chars)
1402 (Fdefine_charset_internal, define_charset_internal)
1403 (Fdeclare_equiv_charset, find_charsets_in_text)
1404 (Ffind_charset_region, char_charset, Fiso_charset):
1405 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
1406 (sub_char_table_set, sub_char_table_set_range)
1407 (char_table_set_range, optimize_sub_char_table)
1408 (map_sub_char_table):
1409 Use bool for boolean.
1410 * character.c (str_to_unibyte): Omit last boolean argument; it was
1411 always 0. All callers changed.
1412 * character.h, charset.h: Adjust to match previous changes.
1413 * character.h (char_printable_p): Remove decl of nonexistent function.
1414 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
1415 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
1416 are all boolean, so make them single-bit bitfields.
1418 * lisp.h (ASET): Remove attempt to detect side effects.
1419 It was meant to be temporary and it often doesn't work,
1420 because when IDX has side effects the behavior of IDX==IDX
1421 is undefined. See Stefan Monnier in
1422 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
1424 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
1426 * lisp.h (functionp): New function (extracted from Ffunctionp).
1427 (FUNCTIONP): Use it.
1428 * eval.c (Ffunctionp): Use it.
1430 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1432 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
1433 as that's faster and simpler than static storage. Don't bother
1434 with the g_main_context_query overhead if g_main_context_pending
1435 says no events are pending.
1436 (gfds, gfds_size): Remove these static vars.
1437 (xgselect_initialize): Remove; no longer needed.
1438 All uses and decls removed.
1440 * emacs.c (fatal_error_signal_hook): Remove.
1441 All uses removed. This leftover from old code was always 0.
1443 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
1444 * casefiddle.c (casify_object, casify_region):
1445 * casetab.c (set_case_table):
1446 * category.c, category.h (word_boundary_p):
1447 * category.h (CHAR_HAS_CATEGORY):
1448 Use bool for booleans, instead of int.
1450 2012-08-25 Eli Zaretskii <eliz@gnu.org>
1452 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
1454 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1456 On assertion failure, print backtrace if available.
1457 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1458 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1459 * Makefile.in (LIB_EXECINFO): New macro.
1462 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1463 * bytecode.c (exec_byte_code):
1464 * callint.c (check_mark, Fcall_interactively):
1465 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1466 (getenv_internal, sync_process_alive, call_process_exited):
1467 * lisp.h (USE_SAFE_ALLOCA):
1468 Use bool for booleans, instead of int.
1469 * lisp.h, process.h: Adjust prototypes to match above changes.
1470 * callint.c (Fcall_interactively): Don't assume the mark's
1471 offset fits in 'int'.
1473 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1475 * buffer.c, buffer.h: Use bool for boolean.
1476 * buffer.c (reset_buffer_local_variables)
1477 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1478 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
1479 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
1480 (overlay_touches_p, overlay_strings, Foverlay_put)
1481 (report_overlay_modification, call_overlay_mod_hooks):
1482 (mmap_enlarge, mmap_set_vars):
1483 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1484 Use bool for booleans, instead of int.
1485 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1486 since the 1-or-0 return value is always ignored anyway.
1487 (mmap_initialized_p):
1488 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1489 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1491 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1493 * bidi.c: Use bool for boolean.
1494 This is a bit more readable, and makes the text segment of bidi.o
1495 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1496 Presumably it's faster too.
1497 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1499 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1500 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1501 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1502 (bidi_explicit_dir_char, bidi_level_of_next_char)
1503 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1504 Use bool for booleans, instead of int.
1505 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1506 (bidi_unshelve_cache): Adjust decls to match code.
1508 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1510 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1513 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1515 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1516 * atimer.h: Include <stdbool.h>.
1518 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1520 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1521 compile time tests instead of run time tests on systems that do
1523 (FRAME_MAC_P): Remove leftover from deleted code.
1524 * frame.c (syms_of_frame): Remove leftover from deleted code.
1526 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
1528 * nsterm.m (insertText:): Don't clear modifiers if code is space.
1530 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1532 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1533 Otherwise, the compiler complains about (A?B:C) where B is void
1534 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1535 (fontset_add): Return void, for FONTSET_ADD.
1537 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1539 * alloc.c: Use bool for booleans.
1540 (gc_in_progress, abort_on_gc)
1541 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1542 (dont_register_blocks) [GC_MALLOC_CHECK]:
1543 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1544 (check_string_bytes, make_specified_string, memory_full)
1545 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1546 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1547 (mark_stack, valid_pointer_p, make_pure_string)
1548 (Fgarbage_collect, survives_gc_p, gc_sweep):
1549 Use bool for booleans, instead of int.
1550 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1551 Remove unused local.
1552 * alloc.c (PURE_POINTER_P):
1553 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1554 * editfns.c (Fformat):
1555 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1557 * fns.c (sweep_weak_table):
1558 * lisp.h (suppress_checking, push_message, survives_gc_p)
1559 (make_pure_string, gc_in_progress, abort_on_gc):
1560 * lread.c (readchar, read1):
1561 * print.c (Fprin1_to_string):
1562 * xdisp.c (push_message):
1563 Use bool for booleans affected directly or indirectly by
1566 Make recently-introduced setters macros.
1567 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1568 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1569 (set_fontset_default, set_fontset_fallback): Rename from their
1570 upper-case counterparts, and make them functions rather than macros.
1571 This is more consistent with the other recently-introduced setters.
1572 These don't need to be inline, since they're local.
1574 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1576 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1577 the loop (Bug#12247).
1579 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1581 * lisp.h (vcopy): Use memcpy rather than our own loop.
1582 This fixes a performance regression introduced by the recent
1583 addition of vcopy. This means 'vcopy' will need to be modified
1584 for a copying collector, but that's OK. Also, tighten the
1585 checking in the assertion.
1587 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1589 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1590 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1591 non-base glyph for the width of the base character, according to
1592 what x_draw_composite_glyph_string_foreground expects.
1593 Generate WADJUST value according to composition_gstring_width's
1594 expectations, to produce correct width of the composed character.
1595 Reverse the sign of the DU offset produced by ScriptPlace.
1597 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1599 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1601 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1603 Avoid direct writes to contents member of struct Lisp_Vector.
1604 * lisp.h (vcopy): New function to copy data into vector.
1605 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
1606 * fns.c (Ffillarray): Use ASET.
1607 * keyboard.c (timer_check_2): Use AREF and ASET.
1608 (append_tool_bar_item, Frecent_keys): Use vcopy.
1609 * lread.c (read_vector): Use ASET.
1610 * msdos.c (Frecent_doskeys): Use vcopy.
1611 * xface.c (Finternal_copy_lisp_face): Use vcopy.
1612 (Finternal_merge_in_global_face): Use ASET and vcopy.
1613 * xfont.c (xfont_list_pattern): Likewise.
1615 2012-08-21 Martin Rudalics <rudalics@gmx.at>
1617 * window.c (Fwindow_point): For the selected window always return
1618 the position of its buffer's point.
1619 (Fset_window_point): For the selected window always go in its
1620 buffer to the specified position.
1622 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1624 Setter macros for fontsets.
1625 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1626 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1627 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1630 2012-08-20 Glenn Morris <rgm@gnu.org>
1632 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1633 Don't assume that `ln -f' works.
1635 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1637 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1638 and later about non-assignments with no effect. See discussion at
1639 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1642 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1644 Inline setter functions for Lisp_Objects slots of struct specbinding.
1645 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
1648 2012-08-20 Martin Rudalics <rudalics@gmx.at>
1650 * window.c (select_window): Always make selected window's buffer
1653 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1655 Use AREF and ASET for docstrings of category tables.
1656 * category.h (CATEGORY_DOCSTRING): Use AREF.
1657 (SET_CATEGORY_DOCSTRING): Use ASET.
1658 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
1660 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1662 Inline setter functions for hash table members.
1663 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
1664 (set_hash_hash, set_hash_index): Rename with _slot suffix.
1665 (set_hash_key_and_value, set_hash_index, set_hash_next)
1666 (set_hash_hash): New functions.
1667 * charset.c, fns.c: Adjust users.
1669 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1671 Inline getter and setter functions for per-buffer values.
1672 * buffer.h (per_buffer_default, set_per_buffer_default)
1673 (per_buffer_value, set_per_buffer_value): New functions.
1674 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
1675 * buffer.c, data.c: Adjust users.
1677 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
1679 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
1681 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
1683 Rely on <config.h> + <unistd.h> to declare 'environ',
1684 as gnulib does this if the system doesn't.
1685 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
1686 Remove declaration. MS-Windows declares it on stdlib.h which is
1687 included by conf_post.h.
1688 * emacs.c (environ) [DOUG_LEA_MALLOC]:
1689 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
1690 * vm-limit.c: Include <unistd.h>, for 'environ'.
1692 * unexaix.c, unexcoff.c: Include "mem-limits.h".
1693 (start_of_data): Remove decl; mem-limits.h provides it.
1695 * xdisp.c (handle_invisible_prop): Make it a bit faster
1696 and avoid a gcc -Wmaybe-uninitialized diagnostic.
1698 2012-08-19 Chong Yidong <cyd@gnu.org>
1700 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
1703 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
1705 * .gdbinit: Use call instead of set when calling a function in the
1708 * data.c (set_internal): Don't use set_blv_found.
1709 (Fkill_local_variable): Likewise.
1711 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
1713 * nsfont.m (ns_ascii_average_width): Ensure the string
1714 ascii_printable is initialized with a null-terminated character
1715 array. Otherwise, it can contain undesired extra characters.
1717 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1719 port new setting code to Sun C 5.8 2005/10/13
1720 * chartab.c, lisp.h (char_table_set, char_table_set_range):
1721 Return void, not Lisp_Object. Otherwise, the compiler
1722 complains about (A?B:C) where B is void and C is Lisp_Object
1723 when compiling CHAR_TABLE_SET, due to the recent change to
1724 the API of sub_char_table_set_contents.
1726 2012-08-18 Chong Yidong <cyd@gnu.org>
1728 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
1729 for the string case (Bug#3874).
1731 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1733 * buffer.h (BSET): Remove (Bug#12215).

1803 New setter functions.
1805 * termhooks.h (TSET): Remove (Bug#12215).
1806 Replace all uses with calls to new setter functions.
1807 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
1808 (TERMHOOKS_INLINE): New macro.
1809 (tset_charset_list, tset_selection_alist): New setter functions.
1810 * terminal.c (TERMHOOKS_INLINE):
1811 Define to EXTERN_INLINE, so that the corresponding functions
1812 are compiled into code.
1813 (tset_param_alist): New setter function.
1815 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>

2561 value of EMACSLOADPATH, as it is no longer needed.
2562 (check_windows_init_file): Now external, not static.

2568 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

2613 * alloc.c (record_xmalloc): New function.
2614 * lisp.h (record_xmalloc): New decl.
2615 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
2616 more like a function. This is because the pointer cast is not
2617 needed. All uses changed.
2618 * print.c (print_string, print_error_message): Avoid length recalc.
2620 Improve fix for macroexp crash with debugging (Bug#12118).
2621 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
2622 ARRAY_MARK_FLAG when checking subscripts, because ASET is

2625 (gc_aset): New function, which is like ASET but can be
2626 used in the garbage collector.

2655 with addition of handling of symlinks and support for 'lstat'.
2656 If possible, get file's attributes and security information by
2657 handle, not by name. Produce S_IFLNK bit for symlinks, when
2658 called from 'lstat'.
2659 (stat, lstat): New functions, call 'stat_worker'.
2660 (symlink, readlink, careadlinkat): Rewritten to create and resolve
2661 symlinks when the underlying filesystem supports them.
2663 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
2665 Fix macroexp crash on Windows with debugging (Bug#12118).
2666 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
2667 checking subscripts; problem introduced with the recent
2668 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
2669 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
2670 since it's used in non-static inline functions now.
2672 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
2673 Don't assume buffer size fits in 'int'. Remove unused local.

3164 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
3165 arms of an 'if', not using conditional expressions; otherwise GDB
3166 complains about the types in the unevaluated arm when the argument
3167 is an integer literal.
3168 (xgetint): Simplify expression.
3169 * alloc.c (gdb_make_enums_visible): New constant. This ports to
3170 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
3171 Zaretskii in <http://bugs.gnu.org/12036#13>.
3172 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
3173 needed now that we have gdb_make_enums_visible.
3174 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
3175 (enum enum_USE_LSB_TAG):
3176 New enum types, packaging up enums that need to be exported to GDB.

3194 * xdisp.c (syms_of_xdisp): Likewise.
3195 * xfns.c (syms_of_xfns): Likewise.
3197 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3199 Fast save_excursion_save and save_excursion_restore.
3200 * lisp.h (struct Lisp_Excursion): New data type.
3201 (PVEC_EXCURSION): New pseudovector type.
3202 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
3203 to deal with it. Adjust comments.
3204 (init_marker, attach_marker): New prototype.
3205 (unchain_marker): Adjust prototype.
3206 * marker.c (attach_marker): Change to global.

3214 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
3216 Fix export of symbols to GDB (Bug#12036).
3217 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
3218 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
3219 emacs.c, as this is a more-suitable home. Had this been done earlier
3220 the fix for 12036 would have avoided some of the problems noted in
3221 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
3222 would have been more obvious.
3223 * emacs.c: Do not include <verify.h>; no longer needed.
3224 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
3225 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
3226 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3227 Remove; now done in lisp.h.
3228 * lisp.h (PUBLISH_TO_GDB): New macro.
3229 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
3230 (DATA_SEG_BITS): Use it.
3231 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
3232 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3233 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3234 not be usable in #if. This simplifies things.
3236 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
3238 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
3240 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

3243 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3244 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3245 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3246 Adjust to changes in lisp.h and emacs.c, by using
3247 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
3248 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
3249 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
3250 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
3251 instead of gdb_valbits.
3252 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
3253 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
3254 instead of gdb_array_mark_flag.
3255 (xboolvector): Get size from $->size, not $->header.size.
3256 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
3257 (xreload, hook-run, hookpost-run): Remove.
3258 * emacs.c: Include <verify.h>.
3259 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
3260 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
3262 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
3263 (gdb_USE_LSB_TAG): New enum constants.
3264 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3265 Also define these as enum constants, so they're visible to GDB.
3266 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
3267 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
3268 as constants, so they're visible to GDB.
3269 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
3270 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
3271 Now enum constants, not macros, so they're visible to GDB.
3272 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
3273 more convenient now. All uses changed.
3274 (VALMASK) [USE_LSB_TAG]: Also define in this case.
3275 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
3277 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

3282 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
3284 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
3285 add argument, tune behavior, and adjust all callers.
3287 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
3289 Use typedef for EMACS_INT, EMACS_UINT.
3290 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
3291 than macros. This simplifies debugging in the usual case, since
3292 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
3293 and it allows expressions involving EMACS_INT casts.
3294 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
3296 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

3306 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
3308 Adjust buffer text indirection counters at the end of Fkill_buffer.
3309 * buffer.c (Fkill_buffer): Adjust indirection counters when the
3310 buffer is definitely dead. This should really fix an issue reported
3311 by Christoph Scholtes again. (Bug#12007).
3312 (init_buffer_once): Initialize indirection counters of
3313 buffer_defaults and buffer_local_symbols (for sanity and safety).
3315 2012-07-24 Eli Zaretskii <eliz@gnu.org>
3317 * xdisp.c (init_iterator): Don't compute dimensions of truncation
3318 and continuation glyphs on tooltip frames, leave them at zero.

3346 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3348 Swap buffer text indirection counters in Fbuffer_swap_text.
3349 * buffer.c (Fbuffer_swap_text): Swap indirections too.
3350 This avoids crash reported by Christoph Scholtes at
3351 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
3353 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
3355 * nsmenu.m (Popdown_data): New struct.

3360 and autorelease them. Also autorelease img and matrix (Bug#12005).
3361 (dealloc): Remove (Bug#12005).

3378 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
3380 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
3381 as it's limited by the amount of memory, not by INT_MAX.
3383 2012-07-21 Eli Zaretskii <eliz@gnu.org>
3385 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
3386 in special-event-map. See the discussion at

3467 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
3468 'for_each_per_buffer_object_at'.
3469 All uses changed. It's better to use upper-case for macros that

3519 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
3521 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
3523 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
3524 when invoking (make-bool-vector N t) and N is a positive

3532 padding before the data member of a bool vector.
3533 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
3534 than doing the check by hand with an abort ().
3536 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3538 * eval.c (Fdefvar): Don't check constants since we only set the var if
3539 it's not yet defined anyway (bug#11904).
3541 * lisp.h (last_undo_boundary): Declare new var.
3542 * keyboard.c (command_loop_1): Set it.
3543 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
3544 were auto-added by the command loop (bug#11774).
3546 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
3548 * w32font.c (Qsymbol): Remove local definition.

4042 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
4043 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

4046 * s/gnu-linux.h, s/hpux10-20.h, s/template.h, s/usg5-4-common.h:
4047 Move CLASH_DETECTION to configure.
4049 * s/gnu.h: Remove file, which is now empty.
4051 * s/gnu.h, s/gnu-linux.h:
4052 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
4054 2012-07-11 John Wiegley <johnw@newartisans.com>
4056 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
4057 function attribute, so we only use it if it exists in the
4060 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
4062 Avoid call to strlen in fast_c_string_match_ignore_case.
4063 * search.c (fast_c_string_match_ignore_case): Change to use
4064 length argument. Adjust users accordingly.
4065 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
4067 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

4088 (font_open_by_name): Change to use length argument.
4089 Adjust users accordingly.
4090 * font.h (font_open_by_name, font_parse_xlfd, font_unparse_xlfd):
4092 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
4093 Change to return ptrdiff_t.
4094 (xfont_list_pattern, xfont_match): Use length returned by
4095 xfont_decode_coding_xlfd.

4106 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
4108 Remove "#define unix" that is no longer needed (Bug#11905).
4109 * s/aix4-2.h (unix): Remove; no longer needed.
4111 EMACS_TIME simplification (Bug#11875).
4112 This replaces macros (which typically do not work in GDB)
4113 with functions, typedefs and enums, making the code easier to debug.
4114 The functional style also makes code easier to read and maintain.
4115 * systime.h: Include <sys/time.h> on all hosts, not just if
4116 WINDOWSNT, since 'struct timeval' is needed in general.
4117 (EMACS_TIME): Now a typedef, not a macro.
4118 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
4120 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

4122 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
4123 (EMACS_TIME_LE): Now functions, not macros.
4124 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
4125 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
4126 which are not functions. All uses rewritten to use:
4127 (make_emacs_time): New function.
4128 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
4129 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4130 not functions. All uses rewritten to use the following, respectively:
4131 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
4132 (add_emacs_time, sub_emacs_time): New functions.
4133 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
4134 * fileio.c (Fcopy_file):
4135 * xterm.c (XTflash): Get the current time closer to when it's used.
4136 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

4142 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
4143 * frame.c (Fmake_terminal_frame):
4144 * gtkutil.c (get_utf8_string):
4146 * nsmenu.m (ns_update_menubar):
4147 * regex.c (regerror):
4148 Prefer memcpy to strncpy and strncat when either will do.
4149 * fileio.c (Fsubstitute_in_file_name):
4150 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
4151 (menu_separator_name_p):
4152 * nsmenu.m (ns_update_menubar):
4153 Prefer memcmp to strncmp when either will do.
4154 * nsterm.m: Include <ftoastr.h>.
4156 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
4157 Prefer snprintf to strncpy.
4158 * nsterm.m (ns_term_init):
4159 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4160 * nsterm.m (ns_term_init):
4161 Avoid the need for strncpy, by using build_string or
4162 make_unibyte_string directly. Use dtoastr, not snprintf.
4163 * process.c (Fmake_network_process): Diagnose service names that
4164 are too long, rather than silently truncating them or creating
4165 non-null-terminated names.
4166 (Fnetwork_interface_info): Likewise, for interface names.
4167 * sysdep.c (system_process_attributes) [GNU_LINUX]:
4168 Prefer sprintf to strncat.
4169 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
4170 Prefer vsnprintf to vsprintf + strncpy.
4172 2012-07-10 Glenn Morris <rgm@gnu.org>
4174 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
4175 Clarify fallback case.
4177 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4179 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
4180 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
4181 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
4182 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
4183 where argument type is known to be a Lisp_Cons.
4185 2012-07-10 Tom Tromey <tromey@redhat.com>
4187 * bytecode.c (BYTE_CODE_THREADED): New macro.
4188 (BYTE_CODES): New macro. Replaces all old byte-code defines.
4189 (enum byte_code_op): New type.
4190 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.

4193 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4195 Optimize pure C strings initialization.
4196 * lisp.h (make_pure_string): Fix prototype.
4197 (build_pure_c_string): New function, defined as static inline. This
4198 provides a better opportunity to optimize away calls to strlen when
4199 the function is called with compile-time constant argument.
4200 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
4201 argument, adjust users accordingly. Use build_pure_c_string where
4203 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
4204 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
4205 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
4207 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4209 Avoid calls to strlen in miscellaneous functions.
4210 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
4211 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
4212 * lread.c (openp): Likewise.
4214 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4216 Avoid calls to strlen in path processing functions.
4217 * fileio.c (file_name_as_directory): Add comment. Change to add
4218 srclen argument and return the length of result. Adjust users
4220 (directory_file_name): Fix comment. Change to add srclen argument,
4221 swap 1st and 2nd arguments to obey the common convention.
4222 Adjust users accordingly.
4223 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
4225 2012-07-10 Glenn Morris <rgm@gnu.org>
4227 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
4228 Move PENDING_OUTPUT_COUNT definition to configure.
4230 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
4231 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
4232 * s/gnu.h (DATA_START): Move definitions to configure.
4234 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
4235 We include usg5-4-common.h, which defines them both.
4237 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
4238 O_RDONLY already includes it).
4240 Stop ns builds setting the EMACSLOADPATH environment variable.
4241 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4242 Now it does not set EMACSLOADPATH, just returns the load-path string.
4243 * nsterm.h: Update accordingly.
4244 * lread.c [HAVE_NS]: Include nsterm.h.
4245 (init_lread) [HAVE_NS]: Use ns_load_path.
4246 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
4248 2012-07-09 Glenn Morris <rgm@gnu.org>
4250 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
4251 since the included bsd-common.h does so.
4253 Stop ns builds setting the EMACSPATH environment variable.
4254 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
4255 (ns_init_paths): Do not set EMACSPATH.
4256 * nsterm.h (ns_exec_path): Add it.
4257 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
4260 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
4262 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
4264 * process.c (wait_reading_process_output): 'waitchannels' was unset
4265 when read_kbd || !NILP (wait_for_cell); fix this.
4267 Add GCC-style 'const' attribute to functions that can use it.
4268 * character.h (char_resolve_modifier_mask):
4269 * keyboard.h (make_ctrl_char):
4270 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
4271 (init_character_once, next_almost_prime, init_fns, init_image)
4272 (flush_pending_output, init_sound):
4273 * mem-limits.h (start_of_data):
4274 * menu.h (finish_menu_items):
4275 Add ATTRIBUTE_CONST.

4277 Declare the dummy function with ATTRIBUTE_CONST.
4278 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
4279 Add decls with ATTRIBUTE_CONST.
4281 Minor improvements to make_formatted_string.
4282 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
4283 where int is good enough, as vsprintf returns an int.
4284 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
4286 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4288 Use make_formatted_string to avoid double length calculation.
4289 * lisp.h (make_formatted_string): New prototype.
4290 * alloc.c (make_formatted_string): New function.
4291 * buffer.c (Fgenerate_new_buffer_name): Use it.

4295 * frame.c (make_terminal_frame, set_term_frame_name)
4296 (x_report_frame_params): Likewise.
4297 * image.c (gs_load): Likewise.
4298 * minibuf.c (get_minibuffer): Likewise.

4313 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4315 Move marker debugging code under MARKER_DEBUG.
4316 * marker.c (MARKER_DEBUG): Move marker debugging code under
4317 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4318 for bootstrap with --enable-checking (~3x slowdown reported
4319 by Juanma Barranquero <lekktu@gmail.com>).
4320 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4322 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4324 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
4325 See <http://bugs.gnu.org/11825#29>.
4327 2012-07-08 Eli Zaretskii <eliz@gnu.org>
4329 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4330 has no font, use the frame's font. (Bug#11813)
4331 (display_line): Add commentary about displaying truncation glyphs
4333 (produce_special_glyphs): Move here from term.c.
4335 * term.c (produce_special_glyphs): Move to xdisp.c.
4337 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4340 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4342 * xdisp.c (display_line): Avoid warning about implicit declaration
4345 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4347 * lisp.h: Remove empty conditional.
4349 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4351 * lread.c (load_path_check): Now static.
4353 Fix some minor --with-ns problems found by static checking.
4354 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
4355 (x_set_font) [!HAVE_X_WINDOWS]:
4356 * image.c (xpm_load_image) [HAVE_NS]:
4357 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4358 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4359 Remove unused local.
4360 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
4361 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
4362 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
4363 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
4364 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
4365 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
4366 Fix pointer signedness problem.
4367 * xfaces.c (FRAME_X_FONT_TABLE):
4368 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
4370 2012-07-07 Glenn Morris <rgm@gnu.org>
4372 * lread.c (load_path_check): New function, split from init_lread.
4373 (init_lread): Reorganize. Motivation:
4374 If EMACSLOADPATH is set, check/warn about that rather than the
4375 defaults, which we are not going to use. Hence we can remove
4376 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4377 Don't warn if site-lisp directories are missing.
4378 If not installed, start from a blank load-path, since
4379 PATH_LOADSEARCH refers to the eventual installation directories.
4381 2012-07-07 Eli Zaretskii <eliz@gnu.org>
4383 Support truncation and continuation glyphs on GUI frames, when
4384 fringes are disabled. (Bug#11832)
4385 * xdisp.c (init_iterator): Get dimensions of truncation and
4386 continuation glyphs even if on GUI frames.
4387 Adjust it->last_visible_x on GUI frames when the left or right fringes,
4388 or both, are absent.
4389 (start_display, move_it_in_display_line_to): Handle the case of a
4390 GUI frame without a fringe to display continuation or truncation
4392 (insert_left_trunc_glyphs): Support GUI frames: make sure
4393 truncation glyphs overwrite enough glyphs from the current line to
4394 have sufficient space in pixels.
4395 (display_line): Support truncation and continuation glyphs on GUI
4396 frames. If some spare pixels are left on the line after inserting
4397 the truncation glyphs, fill that space with a stretch glyph of a
4398 suitably computed width.
4400 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4401 produce_glyphs, to support GUI sessions.
4403 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4405 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4407 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4409 Do not require float-time's arg to fit in time_t (Bug#11825).
4410 This works better on hosts where time_t is unsigned, and where
4411 float-time is applied to the (negative) difference between two times.
4412 * editfns.c (decode_time_components): Last arg is now double *,
4413 not int *, and means to store all the result as a double, without
4414 worrying about whether the seconds part fits in time_t.
4415 All callers changed.
4416 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4417 All callers changed.
4418 (Ffloat_time): Do not fail merely because the specified time falls
4419 outside of time_t range.
4421 2012-07-07 Glenn Morris <rgm@gnu.org>
4423 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
4424 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

4427 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
4429 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
4430 Update dependencies.
4432 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
4434 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4436 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
4437 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
4438 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
4439 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
4440 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
4441 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
4443 * xfont.c (compare_font_names): Redo to omit the need for casts.
4445 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4447 * xfns.c (Fx_change_window_property): Doc fix.
4448 * w32fns.c (Fx_change_window_property): Doc fix.
4450 * w32fns.c (Fx_window_property): Accept the same arguments as the
4451 X Windows version. Doc fix.
4452 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4454 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4455 Eli Zaretskii <eliz@gnu.org>
4457 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4458 Windows-specific code from nt/config.nt moved here.
4459 Obsolete settings removed.
4461 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4463 * process.c: Avoid unnecessary calls to gettime.
4464 (wait_reading_process_output): Don't get the time of day
4465 when gobbling data immediately and not waiting, as there's no need
4466 for it in that case. This removes a FIXME.
4468 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4470 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4471 is defined (Bug#11768).
4473 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4475 Fix marker debugging code.
4476 * marker.c (byte_char_debug_check): Do not perform the check
4477 if buffer is not multibyte.
4478 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4479 Call byte_char_debug_check with correct arguments.
4481 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4483 Compile marker debugging code only if ENABLE_CHECKING is defined.
4484 * marker.c (byte_char_debug_check, count_markers):
4485 Use only if ENABLE_CHECKING is defined.
4486 (byte_debug_flag): Remove.
4487 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4488 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4490 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4492 Avoid code repetition in marker-related functions.
4493 * marker.c (attach_marker): New function.
4494 (Fset_marker, set_marker_restricted, set_marker_both)
4495 (set_marker_restricted_both): Use it.
4496 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4497 Consistently rename charno to charpos.
4498 (marker_position): Add eassert.
4499 (marker_byte_position): Convert to eassert.
4501 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4503 Simplify list operations in unchain_overlay and unchain_marker.
4504 * buffer.c (unchain_overlay): Simplify. Add comment.
4505 * marker.c (unchain_marker): Simplify. Fix comments.
4507 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4509 Introduce fast path for the widely used marker operation.
4510 * alloc.c (build_marker): New function.
4511 * lisp.h (build_marker): New prototype.
4512 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
4513 * composite.c (autocmp_chars): Likewise.
4514 * editfns.c (buildmark): Remove.
4515 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
4516 (save_restriction_save): Use build_marker.
4517 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
4518 * window.c (save_window_save): Likewise.
4520 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

4523 to avoid redundant calls to unchain_overlay.
4524 * buffer.c (drop_overlay): New function.
4525 (delete_all_overlays, Fdelete_overlay): Use it.
4526 * minibuf.c (get_minibuffer): Fix comment.
4528 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4530 Port to OpenBSD 5.1 amd64.
4531 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4532 This is needed for OpenBSD, and should be harmless on all BSD systems.
4533 Also, include <sys/sysctl.h>, as it should be available on all
4534 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4535 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4536 use p_pid member, not kp_proc.pid.
4538 2012-07-06 Glenn Morris <rgm@gnu.org>
4540 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4542 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4544 More xmalloc and related cleanup.
4545 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

4552 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
4553 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4555 Omit needless casts involving void * pointers and allocation.
4556 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4557 as the former is more robust if P's type is changed.
4558 Prefer xzalloc to xmalloc + memset 0.
4559 Simplify malloc-or-realloc to realloc.
4560 Don't worry about xmalloc returning a null pointer.
4561 Prefer xstrdup to xmalloc + strcpy.
4562 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4564 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4565 alloca of a constant.
4567 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4569 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4570 hscroll is larger than the line width. Fixes long and futile
4571 looping inside extend_face_to_end_of_line (on a TTY) producing
4572 glyphs that are not needed and thrown away.
4574 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4576 * marker.c (set_marker_restricted_both): Simplify by using
4579 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4581 * editfns.c (region_limit): Simplify by using clip_to_bounds.
4583 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
4585 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
4586 not defined (Bug#11768).
4587 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
4588 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
4589 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
4590 followed by gtk_box_set_homogeneous (Bug#11768).
4591 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4592 (update_theme_scrollbar_width, xg_create_scroll_bar):
4593 Use gtk_scrollbar_new (Bug#11768).
4594 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
4595 (is_box_type): New function (Bug#11768).
4596 (xg_tool_item_stale_p): Call is_box_type.
4597 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
4598 with default display (Bug#11768).

4602 * xdisp.c (window_hscroll_limited): New function.
4603 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
4604 coordinates when window's hscroll is set to insanely large
4607 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
4609 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
4610 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
4612 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4615 * lisp.h (xzalloc): New prototype. Omit needless casts.
4616 * alloc.c (xzalloc): New function. Omit needless casts.

4668 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4670 * fileio.c (time_error_value): Check the right error number.
4671 Problem reported by Troels Nielsen in
4672 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
4674 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4676 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
4677 This should be fixed in a better way; see Eli Zaretskii in
4678 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
4679 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
4681 * fileio.c (time_error_value): Rename from special_mtime.
4682 The old name's problems were noted by Eli Zaretskii in
4683 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
4685 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
4686 This variable's comment says Emacs needs at least one GDB-visible
4687 symbol of type enum pvec_type, to work around GDB problems.
4688 The symbol's value doesn't matter.
4690 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
4691 that causes compilation to fail on pre-C99 compilers.
4693 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
4695 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
4696 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
4698 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4700 * buffer.c (init_buffer_once): Fix initialization of
4701 headers for buffer_defaults and buffer_local_symbols.
4702 Reported by Juanma Barranquero <lekktu@gmail.com>.
4704 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
4706 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
4707 * lisp.h (enum pvec_type): Use fewer bits.
4708 (PSEUDOVECTOR_SIZE_BITS): New constant.
4709 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
4710 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
4711 change in pvec_type.
4712 (PSEUDOVECTOR_TYPEP): New macro.
4713 (TYPED_PSEUDOVECTORP): Use it.
4714 * fns.c (internal_equal): Adapt code to extract pvectype.

4718 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
4719 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
4720 (sweep_vectors): Use it. Use local var `total_bytes' instead of
4721 abusing vector->header.next.nbytes.
4722 (live_vector_p): Use PVEC_TYPE.
4723 (mark_object): Adapt code to extract pvectype. Use switch.
4725 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4727 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
4728 Tighten new eassert a bit.
4730 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4732 Fix compilation with --enable-gcc-warnings and -O1
4734 * doprnt.c (doprnt): Change type of tem to int, initialize
4735 to avoid compiler warning. Add eassert.
4736 * search.c (simple_search): Initialize match_byte to avoid
4737 compiler warning. Add eassert.
4739 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4741 Avoid weird behavior with large horizontal scrolls.
4742 Without this change, for example, large hscroll values would
4743 mess up Emacs's display on Fedora 15 x86, presumably due to
4744 overflows in int calculations in the display code.
4745 Also, if buffers had long lines, Emacs would freeze.
4746 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
4747 (set_window_hscroll): New function, containing the old guts of
4748 Fset_window_hscroll. Return the clipped value.
4749 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
4750 This avoids the need to check against PTRDIFF_MAX.
4752 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
4754 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4756 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
4758 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4760 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
4761 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
4762 since GCC 4.4.6 issues a bogus warning for them.
4764 Fix bugs in file timestamp newness comparisons.
4765 * fileio.c (Ffile_newer_than_file_p):
4766 * lread.c (Fload): Use full timestamp resolution of files,
4767 not just the 1-second resolution, so that files that are only
4768 slightly newer still count as newer.
4769 * fileio.c (Ffile_newer_than_file_p): Don't assume file
4770 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
4772 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
4774 * fileio.c: Improve handling of file time marker. (Bug#11852)
4775 (special_mtime): New function.
4776 (Finsert_file_contents, Fverify_visited_file_modtime):
4777 Use it to set special mtime values consistently.
4779 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
4781 * fileio.c (Finsert_file_contents): Properly handle st_mtime
4782 marker for non-existing file. (Bug#11852)
4784 2012-07-03 Glenn Morris <rgm@gnu.org>
4786 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
4787 and did not make it into globals.h).
4789 2012-07-03 Tom Tromey <tromey@redhat.com>
4791 * window.c (Fset_window_margins, Fset_window_fringes)
4792 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
4793 * textprop.c (Fprevious_property_change): No longer static.

4816 * intervals.h: Remove EXFUNs.
4817 * fontset.h: Remove EXFUN.

4822 * w32term.h: Remove EXFUNs.
4823 * window.h: Remove EXFUNs.
4824 * xsettings.h: Remove EXFUN.
4825 * xterm.h: Remove EXFUN.
4827 2012-07-03 Glenn Morris <rgm@gnu.org>
4829 * lisp.h (Frandom): Make it visible to C.
4830 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
4831 buffer for invisible buffers. (Bug#1229)
4833 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4835 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
4836 values which aren't power of 2.
4837 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
4838 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
4841 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
4843 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
4845 * alloc.c (mark_object): Revert part of last patch to use `switch'.
4847 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4849 * alloc.c (allocate_vector_block): Remove redundant
4850 calls to mallopt if DOUG_LEA_MALLOC is defined.
4851 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
4852 avoid calls to mallopt if zero_vector is returned.
4854 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4856 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
4857 is enabled, avoid dereferencing NULL current_sblock if
4860 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4862 Cleanup basic buffer management.
4863 * buffer.h (struct buffer): Change layout to use generic vector
4864 marking code. Fix some comments. Change type of 'clip_changed'
4865 to bitfield. Remove unused #ifndef old.
4866 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
4867 (GET_OVERLAYS_AT): Fix indentation.
4868 (for_each_per_buffer_object_at): New macro.
4869 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
4870 (Fbuffer_local_variables): Use it.
4871 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
4872 * alloc.c (allocate_buffer): Adjust to match new layout of
4873 struct buffer. Fix comment.
4874 (mark_overlay): New function.
4875 (mark_buffer): Use it. Use mark_vectorlike to mark normal
4876 Lisp area of struct buffer.
4877 (mark_object): Use it. Adjust marking of misc objects
4878 and related comments.
4880 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
4882 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
4883 wrapper that is not needed because the wrapped code is a no-op (zero
4884 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
4885 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
4887 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
4889 * alloc.c (mark_buffer): Simplify. Remove prototype.
4890 (mark_object): Add comment. Reorganize marking of vector-like
4891 objects. Use CHECK_LIVE for all vector-like objects except buffers
4892 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
4893 Avoid redundant calls to mark_vectorlike for bool vectors.
4895 2012-06-30 Glenn Morris <rgm@gnu.org>
4897 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
4899 * epaths.in (PATH_SITELOADSEARCH): New.
4900 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
4901 This is rather than relying on --enable-locallisppath elements
4902 having "site-lisp" in their names. (Bug#10208#25, 11658)
4904 2012-06-30 Eli Zaretskii <eliz@gnu.org>
4906 * w32proc.c (sys_select): Accept and ignore one more argument.
4908 * w32.c (emacs_gnutls_pull): Call select with one more argument.
4910 * sysselect.h [DOS_NT]: Don't include sys/select.h.
4911 (pselect) [!MS_DOS]: Redirect to sys_select.
4913 * sysdep.c: Don't include dos.h and dosfns.h.
4915 * process.c (sys_select):
4916 * msdos.c (sys_select): Accept one more argument and ignore it.
4918 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
4919 adapt data types and code to that.
4922 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
4923 which clashes with the gnulib function of the same name.
4925 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
4927 * font.c (font_style_to_value, font_style_symbolic)
4928 (font_prop_validate_style): Add type checks for values in
4931 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
4933 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
4936 2012-06-29 Eli Zaretskii <eliz@gnu.org>
4938 * xdisp.c (try_window_id): Undo last change.
4940 * w32.c (getwd): Adjust commentary about startup_dir.
4941 (init_environment): Always call sys_access, even in non-MSVC
4942 builds. Don't chdir to the directory of the Emacs executable.
4943 This undoes code from 1997 which was justified by the need to
4944 "avoid conflicts when removing and renaming directories". But its
4945 downside was that every relative file name was being interpreted
4946 relative to the directory of the Emacs executable, which can never
4947 be TRT. In particular, it broke sys_access when called with
4948 relative file names.
4949 (sys_access): Map GetLastError to errno.
4951 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4953 * window.h (struct window): Change type of 'fringes_outside_margins'
4954 to bitfield. Fix comment. Adjust users accordingly.

5143 Use sprintf return value instead of invoking strlen on result.
5144 In the old days this wasn't portable, since some sprintf
5145 implementations returned char *. But they died out years ago and
5146 Emacs already assumes sprintf returns int.
5147 Similarly for float_to_string.
5148 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

5156 Use sprintf or float_to_string result to avoid need to call strlen.
5157 * data.c (Fnumber_to_string):
5158 Use make_unibyte_string, since the string must be ASCII.
5159 * lisp.h, print.c (float_to_string): Now returns int length.
5160 * term.c (produce_glyphless_glyph):
5161 Use sprintf result rather than recomputing it.
5163 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
5164 * Makefile.in (ALL_CFLAGS):
5165 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

5194 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
5196 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

5199 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
5201 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
5202 instead of truncating it to 63 (admittedly a generous limit).

5262 * keyboard.c (kbd_buffer_get_event):
5263 * process.c (Faccept_process_output):
5264 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
5265 This improves on the previous patch, which introduced a bug
5266 when time_t is unsigned and as wide as intmax_t.
5267 See <http://bugs.gnu.org/9000#51>.
5269 2012-06-23 Eli Zaretskii <eliz@gnu.org>

5332 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5334 Support higher-resolution time stamps (Bug#9000).
5335 The time stamps are only nanosecond-resolution at the C level,
5336 since that's the best that any real-world system supports now.
5337 But they are picosecond-resolution at the Lisp level, as that's
5338 easy, and leaves room for future OS improvements.
5340 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5343 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5344 Don't get current time unless it's needed.
5346 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5347 now provides it if it's absent.
5348 (start_atimer): Port to higher-res time stamps.
5349 Check for time stamp overflow. Don't get current time more
5350 often than is needed.
5352 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5353 Include systime.h, not time.h.
5354 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
5356 * dired.c: Include stat-time.h.
5357 (Ffile-attributes): File times now have higher resolution.
5359 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
5360 (struct image): Timestamp now has higher resolution.
5362 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5363 has at least microseconds now. All uses removed.
5364 (update_frame, update_single_window, update_window, update_frame_1)
5365 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5366 (duration_to_sec_usec): Remove; no longer needed.
5368 * editfns.c (time_overflow): Now extern.
5369 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
5370 (float-time, Fformat_time_string, Fcurrent_time_string)
5371 (Fcurrent_time_zone): Accept and generate higher-resolution
5373 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
5374 (decode_time_components, lisp_seconds_argument): New functions.
5375 (make_time): Now static.
5376 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
5377 Report an error if the time is invalid, rather than having the caller
5380 * fileio.c: Include <stat-time.h>
5381 (Fcopy_file): Copy higher-resolution time stamps.
5382 Prefer to set the time stamp via a file descriptor if that works.
5383 (Fset_file_times, Finsert_file_contents, Fwrite_region)
5384 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
5385 (Fvisited_file_modtime, Fset_visited_file_modtime):
5386 Support higher-resolution time stamps.
5388 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
5390 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
5392 * image.c (prepare_image_for_display, clear_image_cache)
5393 (lookup_image): Port to higer-resolution time stamps.
5395 * keyboard.c (start_polling, bind_polling_period):
5396 Check for time stamp overflow.
5397 (read_char, kbd_buffer_get_event, timer_start_idle)
5398 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
5399 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5400 Port to higher-resolution time stamps. Do not assume time_t is signed.
5401 (decode_timer): New function. Timers are now vectors of length 9,
5402 not 8, to accommodate the picosecond component.
5403 (timer_check_2): Use it.
5405 * nsterm.m (select_timeout, timeval_subtract): Remove.
5406 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5407 as they're a bit more accurate and handle overflow better.
5408 (ns_select): Change prototype to be compatible with pselect.
5409 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5410 * nsterm.h (ns_select): Adjust prototype.
5412 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5413 us-resolution time stamps.
5414 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5416 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5418 * lisp.h (time_overflow): New decl.
5419 (wait_reading_process_output): First arg is now intmax_t, not int,
5420 to accommodate larger waits.
5422 * process.h (struct Lisp_Process.read_output_delay):
5423 Now counts nanoseconds, not microseconds.
5424 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
5426 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
5427 (wait_reading_process_output):
5428 Port to ns-resolution time stamps.
5429 (Faccept_process_output, wait_reading_process_output):
5430 Check for time stamp overflow. Do not assume time_t is signed.
5431 (select_wrapper): Remove; we now use pselect.
5432 (Fprocess_attributes): Now generates ns-resolution time stamps.
5434 * sysdep.c: Include utimens.h. Don't include utime.h
5435 or worry about struct utimbuf; gnulib does that for us now.
5436 (gettimeofday): Remove; gnulib provides a substitute.
5437 (make_timeval): New function.
5438 (set_file_times): Now sets ns-resolution time stamps.
5439 New arg FD; all uses changed.
5440 (time_from_jiffies, ltime_from_jiffies, get_up_time)
5441 (system_process_attributes):
5442 Now returns ns-resolution time stamp. All uses changed.
5443 Check for time stamp overflow.
5445 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5446 provides a substitute now.
5448 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5449 since it guarantees struct timespec.
5450 (EMACS_TIME): Now struct timespec, so that we can support
5451 ns-resolution time stamps.
5452 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5453 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5454 (EMACS_USECS): Remove.
5455 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5456 so multiply the arg by 1000 before storing it.

5459 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

5466 (make_timeval, make_lisp_time, decode_time_components): New decls.
5467 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
5468 that it mishandled time_t overflow. You can't compare by subtracting!
5469 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
5470 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

5498 (timeval_subtract): Remove; no longer needed.
5499 (XTflash, XTring_bell, x_wait_for_event):
5500 Port to ns-resolution time stamps. Don't assume time_t is signed.

5506 2012-06-22 Eli Zaretskii <eliz@gnu.org>
5508 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
5509 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5510 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
5511 staticidx goes up to 1597 out of 1600 = 0x640.)

5515 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
5516 Otherwise, the umask might be mistakenly 0 while handling input signals.

5549 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
5550 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
5551 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
5552 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

5561 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
5562 gets killed during executing of this function (Bug#11665).
5563 Try to always return Qt when the buffer has been actually killed.
5564 (Vkill_buffer_query_functions): In doc-string say that functions
5565 run by this hook should not change the current buffer.
5567 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

5590 This removes the need for CHECK.
5591 (CHECK): Remove. Its comments about always evaluating its
5592 argument were confusing, as 'eassert' typically does not evaluate
5595 * coding.c (produce_chars): Use ptrdiff_t, not int.
5597 * xterm.c (x_draw_underwave): Check for integer overflow.
5598 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

5916 (all_vectors): Rename to `large_vectors'.
5917 (allocate_vector_from_block, init_vectors, allocate_vector_from_block)
5918 (sweep_vectors): New functions.
5919 (allocate_vectorlike): Return `zero_vector' as the only vector of
5920 0 items. Allocate new vector from block if vector size is less than
5921 or equal to VBLOCK_BYTES_MAX.
5922 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
5923 (init_alloc_once): Add call to init_vectors.
5925 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
5927 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
5929 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
5931 * doprnt.c (doprnt): Truncate multibyte char correctly.
5932 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
5933 would mishandle a string argument "Xc" if X was a multibyte
5934 character of length 2: it would truncate after X's first byte
5935 rather than including all of X.
5937 2012-06-06 Chong Yidong <cyd@gnu.org>
5939 * buffer.c (word_wrap): Doc fix.
5941 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>
5943 * xdisp.c (note_mode_line_or_margin_highlight): Pacify gcc -Wall.

5959 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
5962 2012-06-03 Chong Yidong <cyd@gnu.org>
5964 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
5965 (note_mode_line_or_margin_highlight): If there is no help echo,
5966 use mode-line-default-help-echo. Handle the case where the mouse
5967 position is past the end of the mode line string.
5969 * buffer.c (buffer_local_value_1): New function, split from
5970 Fbuffer_local_value; can return Qunbound.
5971 (Fbuffer_local_value): Use it.
5972 (Vmode_line_format): Docstring tweaks.
5974 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5976 * sysdep.c (system_process_attributes): Improve comment.
5978 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
5980 * keyboard.c: Export real-this-command to Elisp.
5981 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
5982 and DEFVAR it. Update all users.
5984 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5986 * minibuf.c (Fassoc_string): Remove duplicate declaration.
5988 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
5989 Convert pctcpu and pctmem to Lisp float properly.
5990 Let the compiler fold better, as 100.0/0x8000 is exact.
5992 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
5994 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
5997 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
5999 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
6001 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
6003 For a 'struct window', replace some Lisp_Object fields to
6004 bitfields where appropriate, remove unused fields.
6005 * window.h (struct window): Remove unused 'last_mark_x' and
6006 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
6007 change it's type from Lisp_Object to bitfield.
6008 Change type of 'force_start', 'optional_new_start',
6009 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
6010 fields from Lisp_Object to bitfield. Adjust users accordingly.
6012 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6014 Pacify gcc -Wdouble-precision when using Xaw.
6015 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
6016 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
6017 Use 'float' consistently, rather than 'float' in most places
6018 and 'double' in a couple of places.
6020 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6022 * xdisp.c (handle_stop): Detect whether we have overlay strings
6023 loaded by testing it->current.overlay_string_index to be
6024 non-negative, instead of checking whether n_overlay_strings is
6025 positive. (Bug#11587)
6027 2012-05-31 Chong Yidong <cyd@gnu.org>
6029 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
6031 * doc.c (Fsubstitute_command_keys): Doc fix.
6033 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6035 * search.c (search_buffer): Remove calls to
6036 r_alloc_inhibit_buffer_relocation, as it is now called by
6037 maybe_unify_char, which was the cause of relocation of buffer text
6040 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6042 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6043 for the duration of call to load_charset, to avoid problems with
6044 callers of maybe_unify_char that access buffer text through C
6047 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6048 decrement the inhibition flag, instead of just setting or
6051 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6053 Remove obsolete '#define static' cruft.
6054 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6055 This #undef was "temporary" in 2000; it is no longer needed
6056 now that '#define static' has gone away.
6057 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6058 (gray_bitmap_bits): Remove; no longer needed.
6059 All uses replaced with definiens.
6060 * xterm.c: Include "bitmaps/gray.xbm".
6062 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6064 Clean up __executable_start, monstartup when --enable-profiling.
6065 The following changes affect the code only when profiling.
6066 * dispnew.c (__executable_start): Rename from safe_bcopy.
6067 Define only on platforms that need it.
6068 * emacs.c: Include <sys/gmon.h> when profiling.
6069 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6070 (__executable_start): Remove decl, since lisp.h does it now.
6071 (safe_bcopy): Remove decl; no longer has that name.
6072 (main): Coalesce #if into single bit of code, for simplicity.
6073 Cast pointers to uintptr_t, since standard libraries want integers
6075 * lisp.h (__executable_start): New decl.
6077 2012-05-31 Glenn Morris <rgm@gnu.org>
6079 * image.c (Fimagemagick_types): Doc fix.
6081 2012-05-30 Jim Meyering <meyering@redhat.com>
6083 * callproc.c (Fcall_process_region): Include directory component
6084 in mkstemp error message (Bug#11586).
6086 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6088 * alloc.c, lisp.h (make_pure_vector): Now static.
6090 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

6093 Move to byte-run.el.
6094 (Fautoload): Do the hash-doc more carefully.
6095 * data.c (Fdefalias): Purify definition, except for keymaps.
6096 (Qdefun): Move from eval.c.
6097 * lisp.h (Qdefun): Remove.
6098 * lread.c (read1): Tiny simplification.
6100 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
6102 Do not create empty overlays with the evaporate property (Bug#9642).
6103 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6104 Bug#9642, but explicitly check that the buffer the overlay would
6105 be moved to is live and rearrange lines to make sure that errors
6106 will not put the overlay in an inconsistent state.
6107 (Fdelete_overlay): Cosmetics.
6109 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6111 * w32term.c (my_bring_window_to_top): New function.
6112 (x_raise_frame): Use handle returned by DeferWindowPos, which
6113 could be different from the original one.
6114 Call my_bring_window_to_top instead of my_set_foreground_window.
6117 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6118 by calling BringWindowToTop.
6120 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6121 (WM_EMACS_END): Increase by one.
6123 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6125 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6126 This avoids undefined behavior that might cause the eassert
6127 to not catch an out-of-range value.
6129 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6131 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
6132 Update dependencies.
6134 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6136 * bidi.c (bidi_mirror_char): Fix last change.
6138 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
6140 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
6141 when referring to sectname field in printf format.
6143 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
6145 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6146 Only r_alloc_inhibit_buffer_relocation needed to be added;
6147 the others were already declared.
6149 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6150 before checking whether it's out of range. Put the check inside
6152 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6154 2012-05-27 Ken Brown <kbrown@cornell.edu>
6156 * callproc.c (Fcall_process): Restore a line that was accidentally
6157 commented out in the 2011-02-13 change (bug#11547).
6159 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6161 * lisp.h [REL_ALLOC]: Add prototypes for external functions
6162 defined on ralloc.c.
6164 * buffer.c [REL_ALLOC]: Remove prototypes of
6165 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
6166 they are now on lisp.h.
6168 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6170 * search.c (search_buffer): Use it to inhibit relocation of buffer
6171 text while re_search_2 is doing its job, because re_search_2 is
6172 passed C pointers to buffer text. (Bug#11519)
6174 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6177 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6178 state after an additional call to move_it_in_display_line_to, keep
6179 the values of it->max_ascent and it->max_descent found for the
6181 (pos_visible_p): Revert the comparison against bottom_y to what it
6182 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
6185 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6187 Fix coding-related core dumps with gcc -ftrapv.
6188 The code was computing A - B, where A and B are pointers, and B is
6189 random garbage. This can lead to core dumps on platforms that
6190 have special pointer registers, and it also leads to core dumps on
6191 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6192 A - B only when B is initialized properly.
6193 * coding.c (coding_set_source, coding_set_destination): Return void.
6194 (coding_change_source, coding_change_destinations): New functions,
6195 with the old behaviors of coding_set_source and coding_set_destination.
6196 All callers that need an offset changed to use these new functions.
6198 2012-05-26 Glenn Morris <rgm@gnu.org>
6200 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
6202 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6204 Extend mouse support on W32 text-mode console.
6205 * xdisp.c (draw_row_with_mouse_face):
6206 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6208 * w32console.c: Include window.h.
6209 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6211 (initialize_w32_display): Initialize mouse-highlight data.
6213 * w32inevt.c: Include termchar.h and window.h.
6214 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6215 moves, call note_mouse_highlight. If help_echo changed, call
6216 gen_help_event to produce help-echo message in the echo area.
6217 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6220 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6222 * lread.c (read1): Simplify slightly to avoid an overflow warning
6223 with GCC 4.7.0 on x86-64.
6225 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6227 * bidi.c (bidi_mirror_char): Revert last change: an int is
6228 definitely wide enough here.
6230 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
6232 Fix integer width and related bugs (Bug#9874).
6233 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
6234 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
6235 (string_bytes, check_sblock, allocate_string_data):
6236 (compact_small_strings, Fmake_bool_vector, make_string)
6237 (make_unibyte_string, make_multibyte_string)
6238 (make_string_from_bytes, make_specified_string)
6239 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
6240 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
6242 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6243 (allocate_pseudovector):
6244 Use int, not EMACS_INT, where int is wide enough.
6245 (inhibit_garbage_collection, Fgarbage_collect):
6246 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6247 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
6248 int might not be wide enough.
6249 (bidi_cache_search, bidi_cache_find, bidi_init_it)
6250 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6251 (bidi_at_paragraph_end, bidi_find_paragraph_start)
6252 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
6253 (bidi_level_of_next_char, bidi_move_to_visually_next):
6254 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6255 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
6256 (Fkill_buffer, Fset_buffer_major_mode)
6257 (advance_to_char_boundary, Fbuffer_swap_text)
6258 (Fset_buffer_multibyte, overlays_at, overlays_in)
6259 (overlay_touches_p, struct sortvec, record_overlay_string)
6260 (overlay_strings, recenter_overlay_lists)
6261 (adjust_overlays_for_insert, adjust_overlays_for_delete)
6262 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
6263 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
6264 (Foverlay_recenter, last_overlay_modification_hooks_used)
6265 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6266 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6267 (validate_region): Omit unnecessary test for b <= e,
6268 since that's guaranteed by the previous test.
6269 (adjust_overlays_for_delete): Avoid pos + length overflow.
6270 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6271 (report_overlay_modification):
6272 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6273 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
6274 Omit pointer cast, which isn't needed anyway, and doesn't work
6275 after the EMACS_INT -> ptrdiff_t change.
6276 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
6277 * buffer.h: Adjust decls to match defn changes elsewhere.
6278 (struct buffer_text, struct buffer):
6279 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6280 Use EMACS_INT, not int, where int might not be wide enough.
6281 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
6282 not int, to avoid needless 32-bit limit on 64-bit hosts.
6283 (exec_byte_code): Use tighter memory-full test, one that checks
6284 for alloca overflow. Don't compute the address of the object just
6285 before an array, as that's not portable. Use EMACS_INT, not
6286 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
6287 * callint.c (Fcall_interactively):
6288 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6289 * callproc.c (call_process_kill, Fcall_process):
6290 Don't assume pid_t fits into an Emacs fixnum.
6291 (call_process_cleanup, Fcall_process, child_setup):
6292 Don't assume pid_t fits into int.
6293 (call_process_cleanup, Fcall_process, delete_temp_file)
6294 (Fcall_process_region):
6295 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6296 (Fcall_process): Simplify handling of volatile integers.
6297 Use int, not EMACS_INT, where int will do.
6298 * casefiddle.c (casify_object, casify_region, operate_on_word)
6299 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
6300 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6301 (casify_object): Avoid integer overflow when overallocating buffer.
6302 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
6303 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
6304 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
6305 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6306 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6307 integers are now checked earlier. All uses replaced with XINT.
6309 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6310 For CCL_MapSingle, check that content and value are in int range.
6311 (ccl_driver, Fregister_code_conversion_map):
6312 Check that Vcode_version_map_vector is a vector.
6313 (resolve_symbol_ccl_program): Check that vector header is in range.
6314 Always copy the vector, so that we can check its contents reliably
6315 now rather than having to recheck each instruction as it's being
6316 executed. Check that vector words fit in 'int'.
6317 (ccl_get_compiled_code, Fregister_ccl_program)
6318 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6319 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
6320 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
6321 contents are in range.
6322 (Fccl_execute_on_string): Check that status is in range.
6323 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
6324 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
6325 Accept and return EMACS_INT, not int, because callers can pass values
6327 (c_string_width, strwidth, lisp_string_width, chars_in_text)
6328 (multibyte_chars_in_text, parse_str_as_multibyte)
6329 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
6330 (str_as_unibyte, str_to_unibyte, string_count_byte8)
6331 (string_escape_byte8, Fget_byte):
6332 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6333 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
6334 avoid mishandling large integers.
6335 * character.h: Adjust decls to match defn changes elsewhere.
6336 * charset.c (load_charset_map_from_file, find_charsets_in_text)
6337 (Ffind_charset_region):
6338 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6339 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
6340 (load_charset_map_from_vector, Fdefine_charset_internal):
6341 Don't assume fixnum fits in int.
6342 (load_charset_map_from_vector, Fmap_charset_chars):
6343 Remove now-unnecessary CHECK_NATNUMs.
6344 (Fdefine_charset_internal): Check ranges here, more carefully.
6345 Don't rely on undefined behavior with signed left shift overflow.
6346 Don't assume unsigned int fits into fixnum, or that fixnum fits
6347 into unsigned int. Don't require max_code to be a valid fixnum;
6348 that's not true for gb10830 4-byte on a 32-bit host. Allow
6349 invalid_code to be a cons, for the same reason. Require code_offset
6350 to be a character. Avoid int overflow if max_char is close
6352 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
6353 this is intended anyway and avoids some undefined behavior.
6354 (load_charset_map): Pass unsigned, not int, as 2nd arg of
6355 INDEX_TO_CODE_POINT, as that's what it expects.

7066 * lisp.h (USE_LSB_TAG):
7067 * mem-limits.h (EXCEEDS_LISP_PTR):
7068 Use VAL_MAX, not VALBITS, in #if.
7069 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
7070 (EMACS_UINT): Define unconditionally now.
7071 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
7072 (BITS_PER_EMACS_INT): New constants, replacing
7073 what used to be in config.h, but not useful in #if.
7074 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
7075 define them any more.
7076 (VAL_MAX): New macro.
7078 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
7079 BITS_PER_EMACS_INT, in #if.
7080 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
7081 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
7082 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
7083 * s/ms-w32.h (DATA_START):
7084 Move here from removed file m/intel386.h.
7085 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
7086 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
7088 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
7090 Assume C89 or later.
7091 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
7092 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
7094 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
7095 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
7096 * textprop.c, tparam.c (NULL): Remove.
7097 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
7098 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
7099 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
7100 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
7101 * xterm.c (input_signal_count): Assume volatile works.
7103 2012-05-21 Ken Brown <kbrown@cornell.edu>
7105 * xgselect.c (xg_select): Fix first argument in call to 'select'
7108 2012-05-20 Ken Brown <kbrown@cornell.edu>
7110 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
7111 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
7113 2012-05-19 Ken Brown <kbrown@cornell.edu>
7115 * xfns.c (x_in_use): Remove `static' qualifier.
7116 * xterm.h (x_in_use): Declare.
7117 * xgselect.c: Include xterm.h.
7118 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
7119 and `display_arg' (bug#9754).
7121 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
7123 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
7125 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
7126 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
7128 2012-05-18 Eli Zaretskii <eliz@gnu.org>
7130 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
7132 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
7133 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
7135 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
7136 reference to image_cache->refcount.
7137 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
7139 2012-05-17 Juri Linkov <juri@jurta.org>
7141 * search.c (Fword_search_regexp, Fword_search_backward)
7142 (Fword_search_forward, Fword_search_backward_lax)
7143 (Fword_search_forward_lax): Move functions to isearch.el
7144 (bug#10145, bug#11381).
7146 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
7148 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
7150 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
7152 * lread.c (init_obarray): Declare Qt and Qnil as special.
7154 2012-05-14 Glenn Morris <rgm@gnu.org>
7156 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
7157 Put "libexec" before "bin", for the sake of init_callproc_1.
7159 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7161 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
7163 * unexaix.c: Port to more-recent AIX compilers.
7164 (report_error, report_error_1, make_hdr, copy_sym)
7165 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
7166 Make arguments const char *, not char *, to avoid violations of C
7167 standard and to fix some AIX warnings reported by Gilles Pion.
7169 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7171 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
7172 already have overlays loaded.
7173 (handle_single_display_spec): Before returning without displaying
7174 fringe bitmap, synchronize the bidi iterator with the main display
7175 iterator, by calling iterate_out_of_display_property.
7176 (iterate_out_of_display_property): Detect buffer iteration by
7177 testing that it->string is a Lisp string.
7178 (get_next_display_element): When the current object is exhausted,
7179 and there's something on it->stack, call set_iterator_to_next to
7180 proceed with what's on the stack, instead of returning zero.
7181 (set_iterator_to_next): If called at the end of a Lisp string,
7182 proceed to consider_string_end without incrementing string
7183 position. Don't increment display vector index past the end of
7184 the display vector. (Bug#11417)
7185 (pos_visible_p): Don't report a position visible when move_it_to
7186 stopped at the last line of window, which happens to be scanned
7187 backwards by the bidi iteration. (Bug#11464)
7189 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7191 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7192 and right-margin display specs even if the spec is invalid or we
7193 are on a TTY, and thus unable to display on the fringes.
7194 That's because the text with the property will not be displayed anyway,
7195 so we need to signal to the caller that this is a "replacing"
7196 display spec. This fixes display when the spec is invalid or we
7199 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7201 * unexaix.c (make_hdr): Fix typo in prototype.
7202 This bug broke the build on AIX. Problem reported by Gilles Pion.
7204 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
7206 * keyboard.c (kbd_buffer_get_event): Read special events also in
7207 batch mode. (Bug#11415)
7209 2012-05-12 Glenn Morris <rgm@gnu.org>
7211 * ns.mk: Update for ns_appbindir no longer having trailing "/".
7213 2012-05-12 Eli Zaretskii <eliz@gnu.org>
7215 * lisp.mk (lisp): Add newcomment.elc.
7217 2012-05-12 Glenn Morris <rgm@gnu.org>
7219 * Makefile.in (MKDIR_P): New, set by configure.
7220 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
7222 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
7224 Remove unused function hourglass_started.
7225 * dispextern.h (hourglass_started):
7226 * w32fns.c (hourglass_started):
7227 * xdisp.c (hourglass_started): Remove.
7229 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7231 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7232 Update dependencies.
7234 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7236 * xgselect.c (xg_select): Put maxfds+1 into a var.
7237 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
7239 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7241 2012-05-10 Dave Abrahams <dave@boostpro.com>
7243 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7244 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7246 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7248 * dbusbind.c (xd_registered_buses): New internal Lisp object.
7249 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7250 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7251 Initialize xd_registered_buses.
7253 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7255 Untag more efficiently if USE_LSB_TAG.
7256 This is based on a proposal by YAMAMOTO Mitsuharu in
7257 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7258 For an admittedly artificial (nth 8000 longlist) benchmark on
7259 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7260 Emacs's overall text size by 1%.
7261 * lisp.h (XUNTAG): New macro.
7262 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7263 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7264 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7265 * eval.c (Fautoload):
7266 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7267 * frame.h (XFRAME): Use XUNTAG.
7269 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7270 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7271 Remove unportable assumptions about print widths of types like
7273 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7274 intptr_t when converting between pointer and integer, to avoid GCC
7275 warnings about wrong width.
7277 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7279 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7280 stack for each reader_thread, instead of defaulting to 8MB
7281 determined by the linker. This avoids failures in creating
7282 subprocesses on Windows 7, see the discussion in this thread:
7283 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7285 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7287 Fix up display of the *Minibuf-0* buffer in the mini window.
7288 * keyboard.c (read_char): Don't clear the echo area if there's no
7290 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7291 contents of *Minibuf-0*) if there's no message displayed in its stead.
7293 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7295 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7298 2012-05-06 Chong Yidong <cyd@gnu.org>
7300 * lisp.mk (lisp): Update.
7302 2012-05-05 Jim Meyering <meyering@redhat.com>
7304 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7306 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7308 * data.c (PUT_ERROR): New macro.
7309 (syms_of_data): Use it. Add new error type `user-error'.
7310 * undo.c (user_error): New function.
7311 (Fprimitive_undo): Use it.
7312 * print.c (print_error_message): Adjust print style for `user-error'.
7313 * keyboard.c (user_error): New function.
7314 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7316 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7318 Do not limit current-time-string to years 1000..9999.
7319 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7320 (Fcurrent_time_string): Support any year that is supported by the
7321 underlying localtime representation. Don't use asctime, as it
7322 has undefined behavior for years outside the range -999..9999.
7324 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7326 Fix race conditions involving setenv, gmtime, localtime, asctime.
7327 Without this fix, interrupts could mess up code that uses these
7328 nonreentrant functions, since setting TZ invalidates existing
7329 tm_zone or tzname values, and since most of these functions return
7330 pointers to static storage.
7331 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7332 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7333 Grow the critical sections to include not just invoking
7334 localtime/gmtime, but also accessing these functions' results
7335 including their tm_zone values if any, and any related TZ setting.
7336 (format_time_string): Last arg is now struct tm *, not struct tm **,
7337 so that the struct tm is saved in the critical section.
7338 All callers changed. Simplify allocation of initial buffer, partly
7339 motivated by the fact that memory allocation needs to be outside
7340 the critical section.
7342 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7344 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7345 with RESET_INTERVAL.
7347 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7348 Remove duplicated buffer name initialization.
7350 2012-05-02 Jim Meyering <jim@meyering.net>
7352 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7354 * xfns.c (x_window): Use xstrdup (Bug#11375).
7356 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7358 * xdisp.c (pos_visible_p): If already at a newline from the
7359 display string before the 'while' loop, don't walk back the glyphs
7360 from it3.glyph_row. Solves assertion violation when the display
7361 string begins with a newline (egg.el). (Bug#11367)
7363 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7365 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7368 2012-05-01 Glenn Morris <rgm@gnu.org>
7370 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7371 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7372 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7373 All were removed before 23.1.
7375 * dispnew.c: Remove HAVE_LIBNCURSES test;
7376 it is always true on relevant platforms.
7378 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7379 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7381 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
7383 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
7385 * .gdbinit (xpr): Remove checks for no longer existing misc types.
7386 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
7389 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
7391 Do not avoid creating empty evaporating overlays (Bug#9642).
7392 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7393 That is, do not delete an evaporating overlay if it becomes
7394 empty after its bounds are adjusted to fit within its buffer.
7395 This fix caused other problems, and I'm reverting it until we get
7396 to the bottom of them.
7398 2012-04-27 Chong Yidong <cyd@gnu.org>
7400 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7402 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7404 * xdisp.c (pos_visible_p): If the window start position is beyond
7405 ZV, start the display from buffer beginning. Prevents assertion
7406 violation in init_iterator when the minibuffer window is scrolled
7409 * window.c (window_scroll_pixel_based): Likewise.
7411 2012-04-27 Chong Yidong <cyd@gnu.org>
7413 * keymap.c (where_is_internal): Doc fix (Bug#10872).
7415 2012-04-27 Glenn Morris <rgm@gnu.org>
7417 * fileio.c (Fcopy_file, Fset_file_selinux_context):
7418 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
7420 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7422 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
7423 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
7425 2012-04-26 Eli Zaretskii <eliz@gnu.org>
7427 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7428 display element, check also the underlying string or buffer
7429 character. (Bug#11341)
7431 * w32menu.c: Include w32heap.h.
7432 (add_menu_item): If the call to AppendMenuW (via
7433 unicode_append_menu) fails, disable Unicode menus only if we are
7434 running on Windows 9X/Me.
7436 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7438 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
7439 (xgetint): Add missing shift for LSB tags.
7441 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7443 * keyboard.c (read_char): Don't wipe echo area for select window
7444 events: These might get delayed via `mouse-autoselect-window'
7447 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
7449 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
7450 manipulation of :loaded-from data.
7452 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
7454 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
7455 now a cons (bug#11311).
7457 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7459 Do not create empty overlays with the evaporate property (Bug#9642).
7460 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7461 if it becomes empty after its bounds are adjusted to fit within
7462 its buffer. Without this fix, in a nonempty buffer (let ((o
7463 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7464 yields an empty overlay that has the evaporate property, which is
7465 not supposed to happen.
7467 Fix minor GTK3 problems found by static checking.
7468 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7469 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7470 (struct _EmacsFixedClass, emacs_fixed_get_type):
7471 Move decls here from emacsgtkfixed.h, since they needn't be public.
7472 (emacs_fixed_get_type): Now static.
7473 (emacs_fixed_class_init): Omit unused local.
7474 (emacs_fixed_child_type): Remove; unused.

7476 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7477 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
7478 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
7479 (EMACS_FIXED_GET_CLASS): Remove; unused.
7480 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
7482 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
7483 Problem reported by Juanma Barranquero for Windows -Wunused-function.
7485 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7487 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
7488 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
7489 (__malloc_size_t, __malloc_ptrdiff_t):
7490 Remove. All uses removed, replaced by the definiens if needed,
7491 since we can assume C89 or better now.
7492 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
7493 (protect_malloc_state, align, get_contiguous_space)
7494 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
7495 (malloc_atfork_handler_child, malloc_enable_thread)

7498 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
7499 (special_realloc, _realloc_internal_nolock, _realloc_internal)
7500 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
7501 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
7502 Define using prototypes, not old style.
7503 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
7504 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
7505 (align): Don't assume that signed integer overflow wraps around.
7506 Omit unused local var.
7507 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
7508 (_free_internal_nolock, memalign, mallochook, reallochook):
7509 Omit no-longer-needed casts.
7510 (valloc): Use getpagesize, not __getpagesize.
7511 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
7512 (struct hdr): The 'magic' member is now size_t, not unsigned long.
7514 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.

7569 since the two debugging options are incompatible.
7570 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7572 (mem_init, mem_insert, mem_insert_fixup):
7573 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

7739 2012-04-11 Daniel Colascione <dancol@dancol.org>
7741 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
7742 against is gone. It's better to use vfork now so that when Cygwin
7743 gains a new, working vfork, we use it automatically (bug#10398).

7800 2012-04-09 Eli Zaretskii <eliz@gnu.org>
7802 * xdisp.c (set_cursor_from_row): If the display string appears in
7803 the buffer at position that is closer to point than the position
7804 after the display string, display the cursor on the first glyph of
7805 the display string. Fixes cursor display when a 'display' text
7806 property immediately follows invisible text. (Bug#11094)
7808 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
7810 composite.c: use 'double' consistently
7811 * composite.c (get_composition_id): Use 'double' consistently
7812 instead of converting 'float' to 'double' and vice versa; this is
7813 easier to understand and avoids a GCC warning.

7862 [!WINDOWSNT]: New macros.
7863 (init_libxml2_functions, libxml2_loaded_p): New functions.
7864 (parse_region): Call fn_xmlCheckVersion instead of using the macro
7865 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
7866 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.

7887 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
7888 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
7889 about subtle differences between FETCH_CHAR* and STRING_CHAR*
7890 macros related to unification of CJK characters. For the details,
7891 see the discussion following the message here:
7892 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

7911 position we get to after a call to move_it_to fails the
7912 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
7913 only if we wind up in a string from display property. (Bug#11063)
7915 * window.c (Fdelete_other_windows_internal): Invalidate the row
7916 and column information about mouse highlight, so that redisplay
7917 restores it after reallocating the glyph matrices. (Bug#7464)
7919 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
7920 string comes from a `display' text property, use the buffer
7921 position of that property as if we actually saw that position in
7923 (move_it_by_lines): Remove the assertion that
7924 "it->current_x == 0 && it->hpos == 0" which can be legitimately
7925 violated when there's a before-string at the beginning of a line.
7928 2012-03-30 Eli Zaretskii <eliz@gnu.org>

7985 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
7986 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
7987 when fetching a multibyte character consumes more bytes than
7988 CHAR_BYTES returns, due to unification of CJK characters in
7989 string_char. (Bug#11073)
7991 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
7993 * process.c (wait_reading_process_output): Handle pty disconnect
7994 by refraining from sending oneself a SIGCHLD (bug#10933).
7996 2012-03-22 Chong Yidong <cyd@gnu.org>

8009 2012-03-20 Eli Zaretskii <eliz@gnu.org>
8011 * w32proc.c (Fw32_set_console_codepage)
8012 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
8015 2012-03-20 Chong Yidong <cyd@gnu.org>
8017 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
8018 to reflect default non-nil value of redisplay-dont-pause.
8020 2012-03-19 Kenichi Handa <handa@m17n.org>
8022 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
8023 it fit in a valid range (Bug#11003).
8025 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8027 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8028 that is not from display property, accept the row as a "cursor
8029 row" if one of the string's character has a non-nil `cursor'
8030 property. Fixes cursor positioning when there are newlines in
8031 overlay strings, e.g. in icomplete.el. (Bug#11035)
8033 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
8035 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
8037 2012-03-12 Chong Yidong <cyd@gnu.org>
8039 * eval.c (inhibit_lisp_code): Rename from
8040 inhibit_window_configuration_change_hook; move from window.c.
8042 * xfns.c (unwind_create_frame_1, Fx_create_frame):
8043 * window.c (run_window_configuration_change_hook)
8044 (syms_of_window): Callers changed.

8059 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
8061 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>

8064 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8067 2012-03-03 Glenn Morris <rgm@gnu.org>
8069 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
8071 2012-03-02 Eli Zaretskii <eliz@gnu.org>
8073 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
8074 position past the first glyph_row that ends at ZV. (Bug#10902)
8075 (redisplay_window, next_element_from_string): Fix typos in
8077 (redisplay_window): Pass to move_it_vertically the margin in
8078 pixels, not in screen lines.
8080 2012-03-02 Glenn Morris <rgm@gnu.org>
8082 * buffer.c (buffer-list-update-hook): Doc fix.
8084 2012-02-29 Eli Zaretskii <eliz@gnu.org>
8086 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
8087 push_it before setting up the iterator for the first overlay
8088 string, even if we have an empty string loaded.
8089 (next_overlay_string): If there's an empty string on the iterator
8090 stack, pop the stack. (Bug#10903)
8092 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8094 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8095 Suggested by Stefan Monnier in
8096 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8097 * alloc.c (widen_to_Lisp_Object): New static function.
8098 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8099 and widening them to Lisp_Objects. This would work even if
8100 USE_LSB_TAG is defined and wide integers are used, which might
8101 happen in a future version of Emacs.
8103 2012-02-25 Chong Yidong <cyd@gnu.org>
8105 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
8108 * xselect.c (Fx_selection_exists_p): Doc fix.
8109 (x_clipboard_manager_save_all): Print an informative message
8110 before saving to clipboard manager.
8112 2012-02-24 Chong Yidong <cyd@gnu.org>
8114 * keyboard.c (process_special_events): Handle all X selection
8115 requests in kbd_buffer, not just the next one (Bug#8869).
8117 2012-02-23 Chong Yidong <cyd@gnu.org>
8119 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
8120 call when setting menu-bar-lines and tool-bar-lines parameters.
8121 (unwind_create_frame_1): New helper function.
8123 * window.c (inhibit_window_configuration_change_hook): New var.
8124 (run_window_configuration_change_hook): Obey it.
8125 (syms_of_window): Initialize it.
8127 2012-02-22 Chong Yidong <cyd@gnu.org>
8129 * xterm.c (x_draw_image_relief): Add missing type check for
8130 Vtool_bar_button_margin (Bug#10743).
8132 2012-02-21 Chong Yidong <cyd@gnu.org>
8134 * fileio.c (Vfile_name_handler_alist): Doc fix.
8136 * buffer.c (Fget_file_buffer): Protect against invalid file
8137 handler return value.
8139 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
8141 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
8142 when computing $valmask.
8144 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8145 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8146 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8147 It's useless in that case, and it can cause problems on hosts
8148 that allocate halves of EMACS_INT values separately.
8149 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8150 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8151 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8152 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8153 it avoids undefined behavior on hosts where shifting right by more
8154 than the word width has undefined behavior.
8156 2012-02-19 Chong Yidong <cyd@gnu.org>
8158 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
8159 (Funhandled_file_name_directory, Ffile_name_as_directory)
8160 (Fdirectory_file_name, Fexpand_file_name)
8161 (Fsubstitute_in_file_name): Protect against invalid file handler
8162 return values (Bug#10845).

8176 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
8178 2012-02-15 Chong Yidong <cyd@gnu.org>
8180 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
8181 marked as special. Also, starting docstrings with * is obsolete.
8183 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
8185 * gnutls.c (emacs_gnutls_write): Fix last change.
8187 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

8196 2012-02-12 Chong Yidong <cyd@gnu.org>
8198 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
8199 as that creates a dangerous corner case.
8201 * window.c (Fdelete_window_internal): Invalidate the mouse
8202 highlight (Bug#9904).
8204 2012-02-12 Glenn Morris <rgm@gnu.org>

8209 * nsselect.m (Fx_own_selection_internal)
8210 (Fx_disown_selection_internal, Fx_selection_exists_p)
8211 (Fx_selection_owner_p, Fx_get_selection_internal):
8212 Sync docs and argument specs with the xselect.c versions.
8214 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
8216 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

8230 2012-02-09 Kenichi Handa <handa@m17n.org>
8232 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
8234 2012-02-07 Chong Yidong <cyd@gnu.org>
8236 * buffer.c (Fbuffer_local_variables)
8237 (buffer_lisp_local_variables): Handle unbound vars correctly;
8238 don't let Qunbound leak into Lisp.
8240 2012-02-07 Glenn Morris <rgm@gnu.org>
8242 * image.c (Fimagemagick_types): Doc fix.
8244 * image.c (imagemagick-render-type): Change it from a lisp object
8245 to an integer. Move the doc here from the lisp manual.

8250 * doc.c (store_function_docstring): Avoid applying docstring of
8251 alias to base function (Bug#2603).
8253 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
8255 * .gdbinit (pp1, pv1): Remove redundant defines.
8258 2012-02-04 Chong Yidong <cyd@gnu.org>

8274 * keyboard.c (adjust_point_for_property): Don't position point
8275 before BEGV. (Bug#10696)
8277 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
8279 Handle overflow when computing char display width (Bug#9496).
8280 * character.c (char_width): Return EMACS_INT, not int.
8281 (char_width, c_string_width): Check for overflow when
8282 computing the width; this is possible now that individual
8283 characters can have unbounded width. Problem introduced
8284 by merge from Emacs 23 on 2012-01-19.
8286 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
8288 * dbusbind.c (Fdbus_register_method): Mention the return value

8301 2012-02-02 Kenichi Handa <handa@m17n.org>
8303 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
8304 0, do not call append_composite_glyph.

8308 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
8310 (x_produce_glyphs): If the component of a composition is a null
8311 string, set it->pixel_width to 1 to avoid zero-width glyph.

8315 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
8316 first 2 arguments are identical. This makes inserting large
8317 output from a subprocess an order of magnitude faster on
8318 MS-Windows, where all sbrk'ed memory is always contiguous.

8376 * character.c (char_width): New function.
8377 (Fchar_width, c_string_width, lisp_string_width):

8403 2012-01-11 Glenn Morris <rgm@gnu.org>
8405 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
8406 from load-path also when installation-directory is nil. (Bug#10208)
8408 2012-01-10 Glenn Morris <rgm@gnu.org>
8410 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.

8417 * xdisp.c (rows_from_pos_range): Accept additional argument
8418 DISP_STRING, and accept any glyph in a row whose object is that
8419 string as eligible for mouse highlight. Fixes mouse highlight of
8420 display strings from overlays. (Bug#10464)
8422 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
8424 emacs: fix an auto-save permissions race condition (Bug#10400)
8425 * fileio.c (auto_saving_dir_umask): New static var.
8426 (Fmake_directory_internal): Use it.
8427 (do_auto_save_make_dir): Set it, instead of invoking chmod after
8428 creating the directory. The old code temporarily assigns
8429 too-generous permissions to the directory.
8430 (do_auto_save_eh): Clear it.
8431 (Fdo_auto_save): Catch all errors, not just file errors, so
8432 that the var is always cleared.

8436 * search.c (scan_buffer): Pass character positions to
8437 know_region_cache, not byte positions. (Bug#6540)

8478 * xmenu.c (x_menu_wait_for_event): Use xg_select for Gtk3 so menus

8485 * callint.c (Fcall_interactively): Don't truncate prompt string.
8487 2011-12-23 Eli Zaretskii <eliz@gnu.org>
8489 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
8490 property that ends at ZV, so that the bidi iteration could be

8938 is set, removing the need for VIRT_ADDRESS_VARIES.
8939 (PURE_P): Use a more-efficient implementation that needs just one

8954 (erase_phys_cursor, update_window_cursor, show_mouse_face)
8955 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
8956 behave as if the cursor position were at the window margin.
8958 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
8959 and the cursor position is out of bounds, behave as if the cursor
8960 position were at the window margin. (Bug#10075)
8962 2011-11-18 Chong Yidong <cyd@gnu.org>
8964 * window.c (Fwindow_combination_limit): Make first argument

9449 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
9451 2011-10-27 Chong Yidong <cyd@gnu.org>
9453 * gnutls.c (emacs_gnutls_deinit): New function.
9454 Deallocate credentials structures as well as calling gnutls_deinit.
9455 (Fgnutls_deinit, Fgnutls_boot): Use it.
9457 * process.c (make_process): Initialize GnuTLS credentials to NULL.
9458 (deactivate_process): Call emacs_gnutls_deinit.
9460 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9462 * image.c (x_create_x_image_and_pixmap):
9463 * w32.c (sys_rename, w32_delayed_load):
9464 * w32font.c (fill_in_logfont):
9465 * w32reg.c (x_get_string_resource): Silence compiler warnings.
9467 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
9469 * w32fns.c (w32_default_color_map): New function,
9470 extracted from Fw32_default_color_map.
9471 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
9473 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
9475 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
9477 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
9479 * keyboard.c (test_undefined): New function (bug#9751).
9480 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
9482 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
9484 * sysdep.c (init_sys_modes): Fix the check for the controlling
9485 terminal (Bug#6649).
9487 2011-10-20 Eli Zaretskii <eliz@gnu.org>
9489 * dispextern.h (struct bidi_it): New member next_en_type.
9491 * bidi.c (bidi_line_init): Initialize the next_en_type member.
9492 (bidi_resolve_explicit_1): When next_en_pos is valid for the
9493 current character, check also for next_en_type being WEAK_EN.
9494 (bidi_resolve_weak): Don't enter the expensive loop if the current
9495 position is before next_en_pos. Record the bidi type of the first
9496 non-ET, non-BN character we find, in addition to its position.
9497 (bidi_level_of_next_char): Invalidate next_en_type when
9498 next_en_pos is over-stepped.
9500 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
9502 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
9503 * editfns.c: Rewrite current-time-zone so that it invokes
9504 the equivalent of (format-time-string "%Z") to get the time zone name.
9505 This fixes a bug when the time zone name contains characters that
9506 need converting from the system time locale to Emacs internal format.
9507 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9508 that patch fixed format-time-string to do the conversion, but
9509 I forgot to fix current-time-zone.
9510 (format_time_string): New function, containing most of
9511 what Fformat_time_string used to contain.
9512 (Fformat_time_string): Rewrite in terms of format_time_string.
9513 This doesn't change this function's behavior.
9514 (current-time-zone): Rewrite to use format_time_string.
9515 This fixes the bug reported by Michael Schierl in
9516 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9517 Jason Rumney's 2007-06-07 change worked around this bug, but
9519 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9521 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9523 * xdisp.c (start_display): If the character at POS is displayed
9524 via a display vector, reset IT->current.dpvec_index to zero.
9525 (try_window_reusing_current_matrix): If a line ends in a display
9526 vector or the next line starts in a display vector, continue
9527 redrawing the window even though the character position of
9528 start_row was reached.
9531 2011-10-18 Chong Yidong <cyd@gnu.org>
9533 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9534 with nobreak-char-display too.
9536 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9538 Fix part 3 of bug#9771.
9539 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9540 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9541 non-neutral characters if the current character is a paragraph
9542 separator (a.k.a. Newline). This avoids running the same
9543 expensive loop twice, once when we consume the preceding newline
9544 and the other time when the line actually needs to be displayed.
9545 Avoid the loop when we see neutrals on the base embedding level
9546 following a character whose directionality is the same as the
9547 paragraph's. This avoids running the expensive loop when a line
9548 ends in a long sequence of neutrals, like control characters.
9549 Add assertion against STRONG_AL type. Slightly rearrange code
9550 that determines the type of a neutral given the first non-neutral
9552 (bidi_level_of_next_char): Set next_en_pos to zero when
9553 invalidating its info.
9555 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9557 * xdisp.c (push_display_prop): Determine whether to record string
9558 or buffer position by IT->string, not by IT->method. Allow
9559 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9560 (move_it_vertically_backward): Don't look for character position
9561 immediately after the newline when in a continuation line.
9564 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9566 * window.c (coordinates_in_window): Rewrite and delabelize
9567 vertical border check. (Bug#5357) (Bug#9618)
9569 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9571 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9572 errors in XSetWindowBorder (bug#9310).
9574 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9576 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9577 avoid crash when xmalloc overrun checking is enabled.
9579 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9581 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9582 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9583 cursor motion with <left> and <right> arrow keys.
9585 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9586 some callers set that themselves.
9588 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9590 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9591 display string and the previous row comes from the same string and
9592 is empty. (Bug#9739) (Bug#9738)
9594 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9596 * doc.c (get_doc_string): Encode file name (bug#9735).
9598 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9600 * bidi.c (bidi_level_of_next_char):
9601 * xdisp.c (get_visually_first_element): Remove old incorrect
9602 comments regarding the Unicode Line Separator character.
9604 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9606 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9608 * alloc.c (Fgc_status): Do not access beyond zombies array
9609 boundary if nzombies > MAX_ZOMBIES.
9610 * alloc.c (dump_zombies): Add missing format specifier.
9612 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9614 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9615 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9617 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9618 Some packages use them to denote characters with modifiers.
9620 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9622 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9623 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9624 matching a pp-number. Rename parameter var to var1.
9626 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9628 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9630 2011-10-08 Glenn Morris <rgm@gnu.org>
9632 * callint.c (Fcall_interactively): Give a more explicit error for the
9633 'c' case with a non-character input. (Bug#8479)
9635 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9637 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9639 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9640 lines that are hscrolled on the left.
9642 * dispnew.c (buffer_posn_from_coords): Account for a possible
9643 presence of header-line. (Bug#4426)
9645 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
9647 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
9648 Don't advertise functionality which we discourage or doesn't work.
9650 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
9652 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
9653 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
9654 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
9655 this makes Emacs dump core during garbage collection on rare
9656 occasions. sizeof is obviously inferior to offsetof here, so
9657 stick with offsetof.
9658 (GC_POINTER_ALIGNMENT): New macro.
9659 (mark_memory): Omit 3rd (offset) arg; caller changed.
9660 Don't assume EMACS_INT alignment is the same as pointer alignment.
9662 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
9664 * keyboard.c (read_key_sequence_remapped): New var.
9665 (read_key_sequence): Compute remapping in the right buffer.
9666 (command_loop_1): Use read_key_sequence's remapping directly.
9668 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
9670 * dired.c (file_name_completion): Don't expand file name.
9671 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
9672 before checking file name handler.
9674 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
9675 they've been requested explicitly (bug#9591).
9677 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
9679 * keymap.c (Fsingle_key_description): Use make_specified_string
9680 instead of build_string to build string from push_key_description.
9683 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9685 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
9686 This fixes a Y2038 bug on 64-bit hosts.
9687 * buffer.c (reset_buffer):
9688 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
9689 (Fclear_buffer_auto_save_failure):
9690 Use 0, not -1, to represent an unset failure time, since time_t
9691 might not be signed.
9693 Remove dependency on glibc malloc internals.
9694 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9695 Move back here from lisp.h, but with their new implementations.
9696 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9697 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
9698 * charset.c (charset_table_init): New static var.
9699 (syms_of_charset): Use it instead of xmalloc. This removes a
9700 dependency on glibc malloc internals. See Eli Zaretskii's comment in
9701 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
9702 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9703 Move back to alloc.c.
9704 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9705 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
9707 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
9709 * nsterm.m (windowDidResize): Call x_set_window_size only when
9710 ns_in_resize is true. Otherwise set pixelwidth/height and
9711 call change_frame_size (Bug#9628).
9713 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9715 Port --enable-checking=all to Fedora 14 x86-64.
9716 * charset.c (syms_of_charset): Also account for glibc malloc's
9717 internal overhead when calculating the initial malloc maximum.
9719 Port --enable-checking=all to Fedora 14 x86.
9720 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9722 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
9723 (overrun_check_realloc, overrun_check_free):
9724 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
9725 That way, xmalloc returns a properly-aligned pointer even if
9726 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
9727 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
9728 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
9729 into account when calculating the initial malloc maximum.
9730 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9731 Move here from alloc.c, so that charset.c can use it too.
9732 Properly align; the old code wasn't right for common 32-bit hosts
9733 when configured with --enable-checking=all.
9734 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9735 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
9737 2011-09-29 Eli Zaretskii <eliz@gnu.org>
9739 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
9742 2011-09-28 Eli Zaretskii <eliz@gnu.org>
9744 * xdisp.c (compute_display_string_end): If there's no display
9745 string at CHARPOS, return -1.
9747 * bidi.c (bidi_fetch_char): When compute_display_string_end
9748 returns a negative value, treat the character as a normal
9749 character not covered by a display string. (Bug#9624)
9751 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
9753 * lread.c (Fread_from_string): Fix typo in docstring.
9755 2011-09-27 Eli Zaretskii <eliz@gnu.org>
9757 * xdisp.c (handle_invisible_prop): If invisible text ends on a
9758 newline, reseat the iterator instead of bidi-iterating there one
9759 character at a time. (Bug#9610)
9760 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
9761 TO_CHARPOS if the bidi iterator is at base embedding level.
9763 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
9765 * lread.c (readevalloop): Use correct code for NBSP.
9766 (read1): Likewise. (Bug#9608)
9768 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
9770 * dbusbind.c (Fdbus_register_signal): When service is not
9771 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
9773 2011-09-25 Glenn Morris <rgm@gnu.org>
9775 * buffer.c (truncate-lines): Doc fix.
9777 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
9779 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
9780 (Fset_window_next_buffers): Doc fix.
9782 2011-09-24 Glenn Morris <rgm@gnu.org>
9784 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
9786 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
9788 Fix minor problems found by static checking.
9789 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
9790 * indent.c (Fvertical_motion): Fix == vs = typo.
9792 2011-09-24 Eli Zaretskii <eliz@gnu.org>
9794 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
9795 Default value is now t. Doc fix.
9797 * indent.c (Fvertical_motion): Compute and apply the overshoot
9798 logic when moving up, not only when moving down. Fix the
9799 confusing name and values of the it_overshoot_expected variable;
9800 logic changes accordingly. (Bug#9254) (Bug#9549)
9802 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
9803 CHARPOS is covered by a display string which includes newlines.
9804 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
9805 is covered by a display string with embedded newlines.
9807 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
9809 * dbusbind.c (Fdbus_register_signal): Add match rule to
9810 Vdbus_registered_objects_table. (Bug#9581)
9811 (Fdbus_register_method, Vdbus_registered_objects_table):
9814 2011-09-24 Jim Meyering <meyering@redhat.com>
9816 do not ignore write error for any output size
9817 The previous change was incomplete.
9818 While it makes emacs --batch detect the vast majority of stdout
9819 write failures, errors were still ignored whenever the output size is
9820 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
9821 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
9822 && echo FAIL: ignored write error
9823 FAIL: ignored write error
9824 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
9825 && echo FAIL: ignored write error
9826 FAIL: ignored write error
9827 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
9829 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
9831 * emacs.c (Fkill_emacs): In noninteractive mode exit
9832 non-successfully if a write error occurred on stdout. (Bug#9574)
9834 2011-09-21 Eli Zaretskii <eliz@gnu.org>
9836 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
9839 * dispextern.h (struct it): Update the comment documenting what
9842 2011-09-20 Eli Zaretskii <eliz@gnu.org>
9844 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
9845 a display string, extend search for cursor position to end of row.
9846 (find_row_edges): If the row ends in a newline from a display
9847 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
9848 Handle the case of a display string with multiple newlines.
9849 (Fcurrent_bidi_paragraph_direction): Fix search for previous
9850 non-empty line. Fixes confusing cursor motion with arrow keys at
9851 the beginning of a line that starts with whitespace.
9853 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9855 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
9858 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
9860 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
9863 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9865 * xdisp.c (display_line): Record maximum and minimum buffer
9866 positions even if no glyphs were produced (e.g., by a zero-width
9867 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
9868 buffer positions that will be removed from the glyph row because
9870 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
9871 column is beyond frame width: don't subtract 1 "pixel" when
9872 computing width of the stretch.
9873 (reseat_at_next_visible_line_start): Undo the change made on
9874 2011-09-17 that saved paragraph information and restored it after
9875 the call to `reseat'. (Bug#9545)
9877 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9879 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
9880 and turn window cursor on if cleared (Bug#9415).
9882 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
9884 * search.c (boyer_moore): Take unibyte characters from pattern
9885 literally. (Bug#9458)
9887 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9889 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
9891 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
9893 Fix minor problem found by static checking.
9894 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
9895 initialized, to pacify gcc -Wuninitialized.
9897 * fileio.c: Report proper errno when syscall falls.
9898 (Finsert_file_contents): Save and restore errno,
9899 so that report_file_error outputs the correct diagnostic.
9900 (Fwrite_region) [CLASH_DETECTION]: Likewise.
9902 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9904 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
9906 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9908 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
9909 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
9911 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9913 * xdisp.c (reseat_at_next_visible_line_start): Keep information
9914 about the current paragraph and restore it after the call to reseat.
9916 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
9917 (bidi_find_paragraph_start): Search back for paragraph beginning
9918 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
9919 (bidi_move_to_visually_next): Only trigger paragraph-related
9920 computations when the last character is a newline or at EOB, not
9921 just any NEUTRAL_B. (Bug#9470)
9923 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
9924 truncated lines if point is covered by a display string. (Bug#9524)
9926 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
9928 * xselect.c: Relax test for outgoing X longs (Bug#9498).
9929 (cons_to_x_long): New function.
9930 (lisp_data_to_selection_data): Use it. Correct the test for
9931 short-versus-long data; it was negated. Break out of vector
9932 loop, for efficiency, when a long datum is discovered.
9934 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
9936 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
9938 2011-09-16 Eli Zaretskii <eliz@gnu.org>
9940 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
9941 GCC PR/17406) by declaring this function with external scope.
9943 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9945 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
9946 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
9948 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
9950 * editfns.c (Fformat): Correctly handle text properties on "%%".
9952 2011-09-15 Eli Zaretskii <eliz@gnu.org>
9954 * xterm.c (x_draw_composite_glyph_string_foreground):
9955 * w32term.c (x_draw_composite_glyph_string_foreground):
9956 * term.c (encode_terminal_code):
9957 * composite.c (composition_update_it, get_composition_id):
9958 * xdisp.c (get_next_display_element)
9959 (fill_composite_glyph_string): Add comments about special meaning
9960 of TAB characters in a composition.
9962 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9964 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
9965 This occurs when processing a multibyte format.
9966 Problem reported by Wolfgang Jenker.
9968 2011-09-15 Johan Bockgård <bojohan@gnu.org>
9970 * xdisp.c (try_cursor_movement): Only check for exact match if
9971 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
9973 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9975 Remove unused external symbols.
9976 * dispextern.h (calc_pixel_width_or_height): Remove decl.
9977 * xdisp.c (calc_pixel_width_or_height): Now static.
9978 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
9979 * indent.c (check_display_width):
9980 * w32term.c: Fix comment to match code.
9981 * xterm.c, xterm.h (x_catching_errors): Remove.
9983 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9985 * xselect.c: Use signed conversions more consistently (Bug#9498).
9986 (selection_data_to_lisp_data): Assume incoming selection data are
9987 signed integers, not unsigned. This is to be consistent with
9988 outgoing selection data, which was modified to use signed integers
9989 in as part of the fix to Bug#9196 in response to Jan D.'s comment
9990 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
9991 expects long, not unsigned long.
9993 2011-09-14 Eli Zaretskii <eliz@gnu.org>
9995 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
9996 computation of loop end. Reported by Johan Bockgård
9999 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
10001 * frame.c (Fother_visible_frames_p): Function deleted.
10003 2011-09-12 Eli Zaretskii <eliz@gnu.org>
10005 * indent.c (compute_motion): Process display vector front to back
10006 rather than the other way around. (Bug#2496)
10008 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
10010 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
10012 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
10014 * minibuf.c (Fread_from_minibuffer): Doc fix.
10016 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10018 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
10019 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
10021 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
10023 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
10024 value for non-existent files.
10026 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10028 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10029 set its "size" to -1. This will set the modtime_size field of
10030 the corresponding buffer to -1, which is what
10031 verify-visited-file-modtime expects for files that do not exist.
10034 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
10036 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10038 * lisp.h: ... from here. push_key_description is no longer
10039 defined in keyboard.c, so its declaration should not be in
10040 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10041 logically belongs with push_key_description.
10043 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10045 * buffer.h: Include <sys/types.h> instead of <time.h>.
10046 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
10047 Problem reported by Herbert J. Skuhra.
10049 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
10051 * xml.c (parse_region): Make the parsing work for
10052 non-comment-starting XML files again (bug#9144).
10054 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
10056 * image.c (gif_load): Fix calculation of bottom and right corner.
10059 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10061 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10062 redisplay in small windows.
10064 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10066 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10068 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10070 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10071 Operate on live windows only.
10073 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10075 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10077 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10079 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10080 only under bidi iteration.
10082 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10084 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10086 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10088 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10089 Without this fix, the command to link temacs failed due to an
10090 undefined symbol __builtin_isnan. This is because
10091 /usr/include/iso/math_c99.h #defines isnan(x) to
10092 __builtin_isnan(x), but the bundled gcc, which identifies itself
10093 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10095 * floatfns.c (isnan): #undef, and then #define to a clone of
10097 (Fisnan): Always define, since it's always available now.
10098 (syms_of_floatfns): Always define isnan at the Lisp level.
10100 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10102 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10104 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10106 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10107 The previous code assumed that file offsets (off_t values) fit in
10108 EMACS_INT variables, which is not true on typical 32-bit hosts.
10109 The code messed up by falsely reporting buffer overflow in cases
10110 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10111 when "big" contains more than 2**29 bytes, even though this
10112 inserts just one byte and does not overflow the buffer.
10113 (Finsert_file_contents): Store file offsets as off_t
10114 values, not as EMACS_INT values. Check for overflow when
10115 converting between EMACS_INT and off_t. When checking for
10116 buffer overflow or for overlap, take the offsets into account.
10117 Don't use EMACS_INT for small values where int suffices.
10118 When checking for overlap, fix a typo: ZV was used where
10119 ZV_BYTE was intended.
10120 (Fwrite_region): Don't assume off_t fits into 'long'.
10121 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10123 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10125 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10127 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10129 sprintf-related integer and memory overflow issues (Bug#9412).
10131 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10132 (esprintf, exprintf, evxprintf): New functions.
10133 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10134 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10135 (modify_event_symbol): Do not assume that the length of
10136 name_alist_or_stem is safe to alloca and fits in int.
10137 (Fexecute_extended_command): Likewise for function name and binding.
10138 (Frecursion_depth): Wrap around reliably on integer overflow.
10139 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10140 since some callers pass EMACS_INT values.
10141 (Fsingle_key_description): Don't crash if symbol name contains more
10142 than MAX_ALLOCA bytes.
10143 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10144 (get_minibuffer): Arg is now EMACS_INT, not int.
10145 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10146 (esprintf, exprintf, evxprintf): New decls.
10147 * window.h (command_loop_level, minibuf_level): Reflect API changes.
10149 * dbusbind.c (signature_cat): New function.
10150 (xd_signature, Fdbus_register_signal):
10151 Do not overrun buffer; instead, report string overflow.
10153 * dispnew.c (add_window_display_history): Don't overrun buffer.
10154 Truncate instead; this is OK since it's just a log.
10156 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10157 even if the time zone offset is outlandishly large.
10158 Don't mishandle offset == INT_MIN.
10160 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10161 when creating daemon; the previous buffer-overflow check was incorrect.
10163 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10164 which has the guts of the old verror function.
10166 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10167 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10169 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10170 (font_unparse_xlfd): Don't blindly alloca long strings.
10171 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10172 fits in int, when using sprintf. Use single snprintf to count
10173 length of string rather than counting it via multiple sprintfs;
10174 that's simpler and more reliable.
10175 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10176 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10177 sprintf, in case result does not fit in int.
10179 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10180 (fontset_from_font): Print it.
10182 * frame.c (tty_frame_count): Now printmax_t, not int.
10183 (make_terminal_frame, set_term_frame_name): Print it.
10184 (x_report_frame_params): In X, window IDs are unsigned long,
10185 not signed long, so print them as unsigned.
10186 (validate_x_resource_name): Check for implausibly long names,
10187 and don't assume name length fits in 'int'.
10188 (x_get_resource_string): Don't blindly alloca invocation name;
10189 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10192 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10193 (xg_check_special_colors, xg_set_geometry):
10194 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10196 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10197 Use esprintf, not sprintf, in case result does not fit in int.
10199 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10200 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10201 it as a large positive number.
10202 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10203 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10205 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10206 in case result does not fit in int.
10208 * print.c (float_to_string): Detect width overflow more reliably.
10209 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10210 buffer overrun. Don't assume list length fits in 'int'. Treat
10211 print length of 0 as 0, not as infinity; to be consistent with other
10212 uses of print length in this function. Don't overflow print length
10213 index. Don't assume hash table size fits in 'long', or that
10214 vectorlike size fits in 'unsigned long'.
10216 * process.c (make_process): Use printmax_t, not int, to format
10217 process-name gensyms.
10219 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10221 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10222 to avoid potential buffer overrun.
10224 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10225 if X resource line is longer than 512 bytes.
10227 * xfns.c (x_window): Make sprintf buffer a bit bigger
10228 to avoid potential buffer overrun.
10230 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10232 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10234 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10236 Integer overflow fixes for scrolling, etc.
10237 Without these, Emacs silently mishandles large integers sometimes.
10238 For example, "C-u 4294967297 M-x recenter" was treated as if
10239 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10241 * xdisp.c (try_window_id): Check Emacs fixnum range before
10242 converting to 'int'.
10244 * window.c (window_scroll_line_based, Frecenter):
10245 Check that an Emacs fixnum is in range before assigning it to 'int'.
10246 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10247 values converted from Emacs fixnums.
10248 (Frecenter): Don't wrap around a line count if it is out of 'int'
10249 range; instead, treat it as an extreme value.
10250 (Fset_window_configuration, compare_window_configurations):
10251 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10253 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10254 that can exceed INT_MAX. Check that EMACS_INT value is in range
10255 before assigning it to the (possibly-narrower) index.
10256 (match_limit): Don't assume that a fixnum can fit in 'int'.
10258 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10261 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10262 (Fvertical_motion): Don't wrap around LINES values that don't fit
10263 in 'int'. Instead, treat them as extreme values. This is good
10264 enough for windows, which can't have more than INT_MAX lines anyway.
10266 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10268 * Require libxml/parser.h to avoid compilation warning.
10270 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10272 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10273 since this reportedly can destroy thread storage.
10275 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10277 * syntax.c (find_defun_start): Update all cache variables if
10278 exiting early (Bug#9401).
10280 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10282 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10284 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10285 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10286 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10288 * term.c (tty_append_glyph): New function.
10289 (produce_stretch_glyph): Static function and its prototype deleted.
10291 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10294 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10296 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10297 when checking :margin (Bug#9390).
10298 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10299 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10300 so that the name doesn't mislead. All uses changed.
10302 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10304 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
10307 2011-08-27 Eli Zaretskii <eliz@gnu.org>
10309 * xdisp.c (move_it_to): Don't bail out early when reaching
10310 position beyond to_charpos, if we are scanning backwards.
10311 (move_it_vertically_backward): When DY == 0, make sure we get to
10312 the first character in the line after the newline.
10314 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10316 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10317 (ccl_driver): Do not generate an out-of-range pointer.
10318 (Fccl_execute_on_string): Remove unnecessary check for
10319 integer overflow, noted by Stefan Monnier in
10320 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10321 Remove a FIXME that didn't need fixing.
10322 Simplify the newly-introduced buffer reallocation code.
10324 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10326 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10328 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10330 Integer and memory overflow issues (Bug#9196).
10332 * doc.c (get_doc_string): Rework so that
10333 get_doc_string_buffer_size is the actual buffer size, rather than
10334 being 1 less than the actual buffer size; this makes xpalloc more
10337 * image.c (x_allocate_bitmap_record, cache_image):
10338 * xselect.c (Fx_register_dnd_atom):
10339 Simplify previous changes by using xpalloc.
10341 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10342 since either will do and ptrdiff_t is convenient with xpalloc.
10344 * charset.c (charset_table_size)
10345 (struct charset_sort_data.priority): Now ptrdiff_t.
10346 (charset_compare): Don't overflow if priorities differ greatly.
10347 (Fsort_charsets): Don't assume list length fits in int.
10348 Check for size-calculation overflow when allocating sort data.
10349 (syms_of_charset): Allocate an initial charset table that is
10350 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10352 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10354 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10355 The actual value is always <= INT_MAX, and leaving it unsigned made
10356 overflow checking harder.
10358 * dispextern.h (struct glyph_matrix.rows_allocated)
10359 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10360 with xpalloc. The values are still always <= INT_MAX.
10362 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10364 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10365 (SAFE_NALLOCA): New macro.
10367 * region-cache.c (struct boundary.pos, find_cache_boundary)
10368 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10369 (set_cache_region, invalidate_region_cache)
10370 (revalidate_region_cache, know_region_cache, region_cache_forward)
10371 (region_cache_backward, pp_cache):
10372 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10373 so that ptrdiff_t * can be passed to xpalloc.
10374 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,

10393 because xmalloc/xrealloc may not return.
10394 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10395 now that we have proper integer overflow checking.
10396 (record_overlay_string, overlay_strings): Catch overflows when
10397 calculating size of overlay_str_buf.
10399 * callproc.c (Fcall_process): Check for size overflow when
10400 calculating size of args2.

10403 require adding more-complicated checks.
10405 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10406 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

10446 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10448 * emacs.c (main): Do not reallocate argv, since there is a null at
10449 the end that can be overwritten, and this way there's no need to
10450 worry about size-calculation overflow.
10451 (sort_args): Check for size-calculation overflow.
10453 * eval.c (init_eval_once, grow_specpdl): Don't update size until

10459 Check for integer overflow.
10460 (x_set_alpha): Do not assume XINT fits in int.
10462 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10463 This is for the members text_lines, text_cols, total_lines, total_cols,
10464 where the system imposes an 'int' limit.
10466 * fringe.c (Fdefine_fringe_bitmap):
10467 Don't update size until alloc works.

10472 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
10473 Check for size-calculation overflow.
10474 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10475 do, as we prefer signed integers.
10476 (id_to_widget.max_size, id_to_widget.used)
10477 (xg_store_widget_in_map, xg_remove_widget_from_map)

10482 * gtkutil.h: Change prototypes to match the above.
10484 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

10580 (X_LONG_MIN): New macros.
10581 Use them to make the following changes clearer.
10582 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

10584 future maintainers not to raise the value too much later.
10585 (SELECTION_QUANTUM): Remove, replacing with ...
10586 (selection_quantum): ... new function, which avoids overflow.
10588 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10589 assumption that selection length fits in 'int'.

10606 Don't store size until memory allocation succeeds.
10607 (x_get_window_property): Plug memory leak on memory exhaustion.
10608 Don't double-block input; malloc is safe here. Don't assume 2**34
10609 - 4 fits in unsigned long. Add an xassert to check
10610 XGetWindowProperty overflow. Be more careful about overflow
10611 calculations, and distinguish size from memory overflow better.
10612 (receive_incremental_selection): When tracing, don't assume
10613 unsigned int is less than INT_MAX.
10614 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

10617 in the range -65535 through -1 fit in an X unsigned short.
10618 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10619 result parameters unless successful. Rely on cons_to_unsigned
10620 to report problems with elements; the old code wasn't right anyway.
10621 (x_check_property_data): Check for int overflow; we cannot use
10622 a wider type due to X limits.

10655 * lisp.h (hash_lookup, hash_put):
10656 * minibuf.c (Ftest_completion):
10657 Use ptrdiff_t for hash table indexes, not int (which is too
10658 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
10659 32-bit --with-wide-int hosts).
10661 * charset.c (Fdefine_charset_internal): Check for integer overflow.
10662 Add a FIXME comment about memory leaks.

10670 with outlandish widths.
10671 * character.h (sanitize_tab_width): Rename from sanitize_width,

10693 exceed limits imposed by XClientMessageEvent, as well as the usual
10694 ptrdiff_t and size_t limits.
10696 * keyboard.c: Overflow, signedness and related fixes.
10697 (make_lispy_movement): Use same integer type in forward decl
10698 that is used in the definition.

10700 Change bufsize argument back to int, undoing my 2011-03-30 change.
10701 We prefer signed types, and int is wide enough here.
10702 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
10703 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
10704 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
10705 length, not size_t. Use ptrdiff_t for index, not int.
10706 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
10707 possibility of integer overflow.

10735 Prefer int to unsigned where either will do.
10736 (tiff_handler): New function, combining the cores of the
10737 old tiff_error_handler and tiff_warning_handler.
10738 This function is rewritten to use vsnprintf and thereby avoid
10739 stack buffer overflows. It uses only the features of vsnprintf
10740 that are common to both POSIX and native Microsoft.
10741 (tiff_error_handler, tiff_warning_handler): Use it.
10742 (tiff_load, gif_load, imagemagick_load_image):
10743 Don't assume :index value fits in 'int'.

10746 the integer types that MagickCropImage accepts. Don't assume
10747 Vimagemagick_render_type has a nonnegative value. Don't assume
10748 size_t fits in 'long'.
10749 (gs_load): Use printmax_t to print the widest integers possible.

10752 2011-08-26 Eli Zaretskii <eliz@gnu.org>
10754 * xdisp.c (redisplay_window): Don't force window start if point

10759 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
10760 the display spec is of the form `(space ...)'.
10761 (handle_display_spec): Return the value returned by
10762 handle_single_display_spec, not just 1 or zero.
10763 (handle_single_display_spec): If the display spec is of the form
10764 `(space ...)', and specifies display in the text area, return 2
10766 (try_cursor_movement): Check for the need to scroll more
10767 accurately, and prefer exact match for point under bidi.
10768 Don't advance `row' beyond the last row of the window.

10786 buffers, return left-to-right.
10787 (set_cursor_from_row): Consider candidate row a win if its glyph
10788 represents a newline and point is on that newline. Fixes cursor
10789 positioning on the newline at EOL of R2L text within L2R
10790 paragraph, and vice versa.
10791 (try_cursor_movement): Check continued rows, in addition to
10792 continuation rows. Fixes unwarranted scroll when point enters a
10793 continued line of R2L text within an L2R paragraph, or vice versa.
10794 (cursor_row_p): Consider the case of point being equal to
10795 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
10796 from the end of a short line to the beginning of a continued line
10797 of R2L text within L2R paragraph.

10816 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
10817 extra slot even if the purpose is char-code-property-table.
10819 2011-08-23 Eli Zaretskii <eliz@gnu.org>
10821 * xdisp.c (redisplay_window): When computing centering_position,
10822 account for the height of the header line. (Bug#8874)
10824 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
10825 instead of CHAR_TO_BYTE. Fixes a crash when a completion
10826 candidate is selected by the mouse, and that candidate has a
10827 composed character under the mouse.
10829 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
10830 coordinates reported by pos-visible-in-window-p for a composed
10831 character in column zero.
10833 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

10841 composed buffer positions.
10843 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
10845 * image.c (gif_load): Don't assume that each subimage has the same
10846 dimensions as the base image. Handle disposal method that is
10847 "undefined" by the gif spec (Bug#9335).

10857 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
10858 from an Org mode buffer to a Speedbar frame.
10860 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
10861 a composition, take its buffer position from IT->cmp_it.charpos.
10862 Fixes cursor positioning at the beginning of a line that begins
10863 with a composed character.
10865 2011-08-18 Eli Zaretskii <eliz@gnu.org>
10867 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
10868 character bidirectional type, use STRONG_L instead. Fixes crashes
10869 in a buffer produced by `describe-categories'.
10871 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
10872 members before the level stack, so they would be saved and
10873 restored when copying iterator state. Fixes incorrect reordering
10874 around TABs covered by display properties.
10876 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
10878 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

10884 Remove unnecessary aborts (Bug#9081).
10886 2011-08-17 Eli Zaretskii <eliz@gnu.org>
10888 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
10889 has no `load' handler, try opening the file locally. (Bug#9311)
10891 2011-08-16 Ken Brown <kbrown@cornell.edu>
10893 * gmalloc.c: Expand comment.
10895 2011-08-16 Eli Zaretskii <eliz@gnu.org>

10948 * xdisp.c (move_it_in_display_line_to): Don't invoke
10949 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
10950 ppos_it. Fixes vertical cursor motion when line beginning is
10951 covered by an image. (Bug#9296)
10953 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
10955 * nsterm.h (ns_run_ascript): Declare.

10959 (ns_run_ascript): New function.
10960 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
10961 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
10962 the event loop. Get status from as_status (Bug#7276).
10964 * nsterm.m (sendEvent): If event is NSApplicationDefined and
10965 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
10966 the event loop (Bug#7276).
10968 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
10970 * gnutls.c (QCgnutls_bootprop_priority)

10992 (Fnetwork_interface_list): Allocate in increments of bytes instead
10993 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
10994 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
10996 (struct ifflag_def): notrailers is smart on OSX.
10997 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
10998 Get hardware address with getifaddrs if available.
11000 2011-08-12 Eli Zaretskii <eliz@gnu.org>
11002 * xdisp.c (iterate_out_of_display_property): xassert that
11003 IT->position is set to within IT->object's boundaries. Break from
11004 the loop as soon as EOB is reached; avoids infloops in redisplay
11005 when IT->position is set up wrongly due to some bug.
11006 Set IT->current to match the bidi iterator unconditionally.
11007 (push_display_prop): Allow GET_FROM_STRING as IT->method on
11008 entry. Force push_it to save on the stack the current
11009 buffer/string position, to be restored by pop_it. Fix flags in
11010 the iterator structure wrt the object coming from a display
11011 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
11012 properties. (Bug#9284)
11014 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
11016 * fontset.c (fontset_get_font_group): Add proper type checks.

11046 2011-08-07 Juri Linkov <juri@jurta.org>
11048 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
11049 to show the arg `TIME' instead of `TIMEVAL'.
11051 2011-08-06 Eli Zaretskii <eliz@gnu.org>
11053 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
11054 display property strides EOL and includes a newline, as in
11055 longlines-mode. (Bug#9254)
11056 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
11057 word-wrap under bidirectional display. (Bug#9224)
11059 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
11060 is non-zero, even if the data buffer is NULL. Fixes a crash in
11061 vertical-motion with longlines-mode. (Bug#9254)
11063 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11065 * bidi.c <bidi_cache_total_alloc>: Now static.

11068 * xdisp.c (display_line): Release buffer allocated for shelved bidi
11071 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
11072 amount allocated this far in `bidi_cache_total_alloc'.
11073 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
11074 non-zero, only free the data buffer without restoring the cache
11075 contents. All callers changed.
11077 * dispextern.h (bidi_unshelve_cache): Update prototype.
11079 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
11080 (move_it_in_display_line, move_it_to)
11081 (move_it_vertically_backward, move_it_by_lines): Replace the call
11082 to xfree to an equivalent call to bidi_unshelve_cache.
11083 (move_it_in_display_line_to): Fix logic of returning
11084 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
11086 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11088 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

11103 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11105 * xterm.c (x_find_topmost_parent): New function.
11106 (x_set_frame_alpha): Find topmost parent window with
11107 x_find_topmost_parent and set the property there also (bug#9181).
11108 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
11110 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>

11136 for a display string or property. If found, set DISP_PROP_P
11139 * bidi.c (bidi_fetch_char): Accept an additional argument
11140 DISP_PROP_P, and pass it to compute_display_string_pos.
11141 Only handle text covered by a display string if DISP_PROP_P is returned
11142 non-zero. All callers of bidi_fetch_char changed.
11144 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
11146 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.

11170 * regex.c (re_comp): Protoize.
11171 (re_exec): Fix return type.
11172 (regexec): Fix type of `ret'. (Bug#9203)
11174 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11176 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
11177 This is needed if max-image-size is a floating-point number.
11179 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11181 * print.c (print_object): Print empty symbol as ##.

11226 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11228 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11229 Without this fix, if a signal arrives just after memory fills up,
11230 'malloc' might be invoked reentrantly.
11232 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11233 In other words, assume that every image size is allowed, on non-X
11234 hosts. This assumption is probably wrong, but it lets Emacs compile.
11236 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11238 * regex.c (re_iswctype): Convert return values to boolean.

11257 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11258 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11259 (bidi_find_other_level_edge):
11260 Use ptrdiff_t instead of EMACS_INT where either will do.
11261 This works better on 32-bit hosts configured --with-wide-int.
11262 (bidi_cache_ensure_space): Check for size-calculation overflow.
11263 Use % rather than repeated addition, for better worst-case speed.
11264 Don't set bidi_cache_size until after xrealloc returns, because it
11266 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11267 (bidi_cache_ensure_space): Also check that the bidi cache size
11268 does not exceed that of the largest Lisp string or buffer. See Eli
11269 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11271 * alloc.c (__malloc_size_t): Remove.
11272 All uses replaced by size_t. See Andreas Schwab's note
11273 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11275 * image.c: Improve checking for integer overflow.
11276 (check_image_size): Assume that f is nonnull, since
11277 it is always nonnull in practice. This is one less thing to
11278 worry about when checking for integer overflow later.
11279 (x_check_image_size): New function, which checks for integer
11280 overflow issues inside X.
11281 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11282 This removes the need for a memory_full check.
11283 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11284 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11285 (xbm_read_bitmap_data): Change locals back to 'int', since
11286 their values must fit in 'int'.
11287 (xpm_load_image, png_load, tiff_load):
11288 Invoke x_create_x_image_and_pixmap earlier,
11289 to avoid much needless work if the image is too large.
11290 (tiff_load): Treat overly large images as if
11291 x_create_x_image_and_pixmap failed, not as malloc failures.
11292 (gs_load): Use x_check_image_size.
11294 * gtkutil.c: Omit integer casts.
11295 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11296 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11298 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11300 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11301 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11302 would wrongly return t on a 64-bit host.
11304 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11305 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11306 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11307 and therefore cause GCC to emit a bogus diagnostic in some cases.
11309 * image.c: Integer signedness and overflow and related fixes.
11310 This is not an exhaustive set of fixes, but it's time to
11311 record what I've got.
11312 (lookup_pixel_color, check_image_size): Remove redundant decls.
11313 (check_image_size): Don't assume that arbitrary EMACS_INT values
11314 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11315 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11316 (tiff_load, imagemagick_load_image):
11317 Check for overflow in size calculations.
11318 (x_create_x_image_and_pixmap): Remove unnecessary test for
11319 xmalloc returning NULL; that can't happen.
11320 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11321 (xpm_color_bucket): Use better integer hashing function.
11322 (xpm_cache_color): Don't possibly over-allocate memory.
11323 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11324 (gif_memory_source):
11325 Use ptrdiff_t, not int or size_t, to record sizes.
11326 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11327 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11328 either works, as we prefer signed integers.
11329 (tiff_read_from_memory, tiff_write_from_memory):
11330 Return tsize_t, not size_t, since that's what the TIFF API wants.
11331 (tiff_read_from_memory): Don't fail simply because the read would
11332 go past EOF; instead, return a short read.
11333 (tiff_load): Omit no-longer-needed casts.
11334 (Fimagemagick_types): Don't assume size fits into 'int'.
11336 Improve hashing quality when configured --with-wide-int.
11337 * fns.c (hash_string): New function, taken from sxhash_string.
11338 Do not discard information about ASCII character case; this
11339 discarding is no longer needed.
11340 (sxhash-string): Use it. Change sig to match it. Caller changed.
11341 * lisp.h: Declare it.
11342 * lread.c (hash_string): Remove, since we now use fns.c's version.
11343 The fns.c version returns a wider integer if --with-wide-int is
11344 specified, so this should help the quality of the hashing a bit.
11346 * emacs.c: Integer overflow minor fix.
11347 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11348 Define only if GNU_LINUX.
11349 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11351 * dispnew.c: Integer signedness and overflow fixes.
11352 Remove unnecessary forward decls, that were a maintenance hassle.
11353 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11355 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11356 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11357 (prepare_desired_row, line_draw_cost):
11358 Use int, not unsigned, where either works.
11359 (save_current_matrix, restore_current_matrix):
11360 Use ptrdiff_t, not size_t, where either works.
11361 (init_display): Check for overflow more accurately, and without
11362 relying on undefined behavior.
11364 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11365 Remove, replacing with the new symbols in lisp.h. All uses changed.
11366 * fileio.c (make_temp_name):
11367 * filelock.c (lock_file_1, lock_file):
11368 * xdisp.c (message_dolog):
11369 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11370 Use pMd etc. instead.
11371 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11372 replacing the pWIDE etc. symbols removed from editfns.c.
11374 * keyboard.h (num_input_events): Now uintmax_t.
11375 This is (very slightly) less likely to mess up due to wraparound.
11378 * buffer.c: Integer signedness fixes.
11379 (alloc_buffer_text, enlarge_buffer_text):
11380 Use ptrdiff_t rather than size_t when either will do, as we prefer
11383 * alloc.c: Integer signedness and overflow fixes.
11384 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11385 (__malloc_size_t): Default to size_t, not to int.
11386 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11387 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11388 Prefer ptrdiff_t to size_t when either would do, as we prefer
11390 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11391 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11392 Now const. Initialize with values that are in range even if char
11394 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11395 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11396 These functions do the right thing with sizes > 2**32.
11397 (check_depth): Now ptrdiff_t, not int.
11398 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11399 Adjust to new way of storing sizes. Check for size overflow bugs
11401 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11402 slightly wrong anyway, as it missed one instance of
11403 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11404 (refill_memory_reserve): Omit needless cast to size_t.
11405 (mark_object_loop_halt): Mark as externally visible.
11407 * xselect.c: Integer signedness and overflow fixes.
11408 (Fx_register_dnd_atom, x_handle_dnd_message):
11409 Use ptrdiff_t, not size_t, since we prefer signed.
11410 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11411 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11412 x_dnd_atoms_size and x_dnd_atoms_length.
11414 * doprnt.c: Prefer signed to unsigned when either works.
11416 * doprnt.c (doprnt):
11418 * xdisp.c (vmessage):
11419 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11420 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11421 prefer signed arithmetic to avoid comparison confusion.
11422 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11423 but is a bit tricky.
11425 Assume freestanding C89 headers, string.h, stdlib.h.
11426 * data.c, doprnt.c, floatfns.c, print.c:
11427 Include float.h unconditionally.
11428 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11429 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11430 * regex.c: Likewise for stddef.h, string.h.
11431 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11432 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11433 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11434 (STDC_HEADERS): Remove obsolete defines.
11435 * sysdep.c: Include limits.h unconditionally.
11437 Assume support for memcmp, memcpy, memmove, memset.
11438 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11439 * regex.c (memcmp, memcpy):
11440 Remove; we assume C89 now.
11442 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11443 (__malloc_safe_bcopy): Remove; no longer needed.
11445 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11446 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11447 well either way, and we prefer signed to unsigned.
11449 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11451 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11452 closes the connection while we're reading (bug#9182).
11454 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11456 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11457 are specified (Bug#9168).
11459 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11461 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11462 Found by GCC static checking and --with-wide-int on a 32-bit host.
11464 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11466 * xdisp.c (compute_display_string_pos): Fix logic of caching
11467 previous display string position. Initialize cached_prev_pos to
11468 -1. Fixes slow-down at the beginning of a buffer.
11470 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11472 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11473 for attrs[LFACE_FONTSET_INDEX].
11475 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11477 * xml.c (parse_region): Remove unused local
11478 that was recently introduced.
11480 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11482 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11483 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11485 * xdisp.c (move_it_in_display_line_to): Record the best matching
11486 position for TO_CHARPOS while scanning the line, and restore it on
11487 exit if none of the characters scanned was an exact match.
11488 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11489 when exact match is impossible due to invisible text, and the
11490 lines are truncated.
11492 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11494 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11497 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11499 Fix a significant slow-down of cursor motion with C-n, C-p,
11500 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11501 auto-repeat under bidi redisplay in fontified buffers.
11502 * xdisp.c (compute_stop_pos_backwards): New function.
11503 (next_element_from_buffer): Call compute_stop_pos_backwards to
11504 find a suitable prev_stop when we find ourselves before
11506 (reseat): Don't look for prev_stop, as that could mean a very long
11508 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11509 <cached_disp_overlay_modiff>: Cache for last found display string
11511 (compute_display_string_pos): Return the cached position if asked
11512 about the same buffer in the same area of character positions, and
11513 the buffer wasn't changed since the time the display string
11514 position was cached.
11516 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11518 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11519 is an integer, which is important for empty lines. (Bug#9149)
11521 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11523 * frame.c (Fmodify_frame_parameters): In tty case, update the
11524 default face if necessary (Bug#4238).
11526 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11528 * editfns.c (Fstring_to_char): No need to explain what a character
11529 is in the docstring (Bug#6576).
11531 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11533 * xml.c (parse_region): Make sure we always return a tree.
11535 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11537 * xml.c (parse_region): If a document contains only comments,
11540 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11542 * xml.c (make_dom): Return comments, too.
11544 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11547 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11548 and the surrounding thread.
11549 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11550 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11551 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11553 * s/openbsd.h (BROKEN_SIGIO): Define.
11554 * unexelf.c (unexec) [__OpenBSD__]:
11555 Don't update the .mdebug section of the Alpha COFF symbol table.
11557 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11559 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11562 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11564 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11565 This fixes some race conditions on the permissions of any newly
11568 * alloc.c (valid_pointer_p): Use pipe, not open.
11569 This fixes some permissions issues when debugging.
11571 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11572 If fchown fails to set both uid and gid, try to set just gid,
11573 as that is sometimes allowed. Adjust the file's mode to eliminate
11574 setuid or setgid bits that are inappropriate if fchown fails.
11576 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11578 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11579 to compare Lisp_Objects.
11580 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11581 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11582 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11584 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11586 * lread.c (read_integer): Unread even EOF character.
11587 (read1): Likewise. Properly record start position of symbol.
11589 * lread.c (read1): Read `#:' as empty uninterned symbol if no
11590 symbol character follows.
11592 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11594 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11595 This works around a problem with the previous change to Fcopy_file.
11596 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11597 and without this change, GCC might complain about discarding
11598 fchown's return value.
11600 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11602 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11604 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11606 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11608 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11610 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11611 it's used from the C level.
11613 * process.c: Use the same condition for POLL_FOR_INPUT in both
11614 keyboard.c and process.c (bug#1858).
11616 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11618 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11619 (Fgnutls_boot): Use it.
11621 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11623 * doc.c (Fsubstitute_command_keys): Revert last change.
11625 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11627 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11628 quotes the next character, and doesn't affect other longer
11629 sequences (bug#8935).
11631 * lread.c (syms_of_lread): Clarify that is isn't only
11632 `eval-buffer' and `eval-defun' that's affected by
11633 `lexical-binding' (bug#8460).
11635 2011-07-15 Eli Zaretskii <eliz@gnu.org>
11637 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11638 bidi redisplay when a line includes both an image and is truncated.
11640 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11642 Fix minor problems found by static checking.
11643 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11644 (elsz): Now a signed constant, not a size_t var. We prefer signed
11645 types to unsigned, to avoid integer comparison confusion. Without
11646 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
11647 "cannot optimize loop, the loop counter may overflow", a symptom
11649 * indent.c (Fvertical_motion): Mark locals as initialized.
11650 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
11652 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
11654 * search.c (Fre_search_backward): Mention `case-fold-search' in
11655 all the re_search_* functions (bug#8138).
11657 * keyboard.c (Fopen_dribble_file): Document when the file is
11660 2011-07-14 Eli Zaretskii <eliz@gnu.org>
11662 * bidi.c (bidi_dump_cached_states): Fix format of displaying
11665 Support bidi reordering of display and overlay strings.
11666 * xdisp.c (compute_display_string_pos)
11667 (compute_display_string_end): Accept additional argument STRING.
11668 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
11669 (reseat_to_string): Initialize bidi_it->string.s and
11670 bidi_it->string.schars.
11671 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
11672 NULL (avoids a crash in bidi_paragraph_init).
11673 Initialize itb.string.lstring.
11674 (init_iterator): Call bidi_init_it only of a valid
11675 buffer position was specified. Initialize paragraph_embedding to
11677 (reseat_to_string): Initialize the bidi iterator.
11678 (display_string): If we need to ignore text properties of
11679 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
11680 original value of -1 will not work with bidi.)
11681 (compute_display_string_pos): First arg is now struct
11682 `text_pos *'; all callers changed. Support display properties on
11684 (compute_display_string_end): Support display properties on Lisp
11686 (init_iterator, reseat_1, reseat_to_string): Initialize the
11687 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
11688 when iterating on a string not from display properties).
11689 (compute_display_string_pos, compute_display_string_end):
11690 Fix calculation of the object to scan. Fixes an error when using
11692 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
11693 base_level_stop; instead, set base_level_stop to BEGV.
11694 Fixes crashes in vertical-motion.
11695 (next_element_from_buffer): Improve commentary for when
11696 the iterator is before prev_stop.
11697 (init_iterator): Initialize bidi_p from the default value of
11698 bidi-display-reordering, not from buffer-local value. Use the
11699 buffer-local value only if initializing for buffer iteration.
11700 (handle_invisible_prop): Support invisible properties on strings
11701 that are being bidi-reordered.
11702 (set_iterator_to_next): Support bidi reordering of C strings and
11704 (next_element_from_string): Support bidi reordering of Lisp
11706 (handle_stop_backwards): Support Lisp strings as well.
11707 (display_string): Support display of R2L glyph rows.
11708 Use IT_STRING_CHARPOS when displaying from a Lisp string.
11709 (init_iterator): Don't initialize it->bidi_p for strings
11711 (reseat_to_string): Initialize it->bidi_p for strings here.
11712 (next_element_from_string, next_element_from_c_string)
11713 (next_element_from_buffer): Add xassert's for correspondence
11714 between IT's object being iterated and it->bidi_it.string
11716 (face_before_or_after_it_pos): Support bidi iteration.
11717 (next_element_from_c_string): Handle the case of the first string

12172 * alloc.c (mark_buffer):
12173 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
12174 (clone_per_buffer_values): Don't assume that
12175 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
12176 This isn't true in general, and it's particularly not true
12177 if Emacs is configured with --with-wide-int.
12178 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
12179 New macros, used in the buffer.c change.

12213 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
12215 Random fixes. E.g., (random) never returned negative values.
12216 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
12217 subseconds part to the entropy, as that's a bit more random.
12218 Prefer signed to unsigned, since the signedness doesn't matter and
12219 in general we prefer signed. When given a limit, use a
12220 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12221 latter isn't right if USE_2_TAGS_FOR_INTS.
12222 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12223 not 0..VALMASK. Don't discard "excess" bits that random () returns.
12225 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
12227 * textprop.c (text_property_stickiness):
12228 Obey Vtext_property_default_nonsticky.

12235 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
12236 This is more efficient than Ffile_directory_p and avoids a minor race.
12238 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
12240 * buffer.c (Foverlay_put): Say what the return value is
12243 * fileio.c (barf_or_query_if_file_exists): Check first if the file
12244 is a directory before asking whether to use the file name
12246 (barf_or_query_if_file_exists): Make the "File is a directory"
12247 error be more correct.
12249 * fns.c (Frequire): Remove the mention of the .gz files, since
12250 that's installation-specific, but keep the mention of
12251 `get-load-suffixes'.

12255 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

12261 (syms_of_gnutls): Remove duplicate DEFSYM for
12262 Qgnutls_bootprop_verify_hostname_error, an error for
12263 Qgnutls_bootprop_verify_error (which is no longer used).
12265 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
12266 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
12267 Also (re)move comments that are misplaced or no longer relevant.
12269 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12271 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

12330 (syms_of_keymap): Defsubr make-composed-keymap.
12331 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

12368 * eval.c (struct backtrace): Simplify and port the data structure.
12369 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12370 signed bit field, as this assumption is not portable and it makes
12371 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12372 "char debug_on_exit : 1" as this is not portable either; instead,
12373 use the portable "unsigned int debug_on_exit : 1". Remove unused
12374 member evalargs. Remove obsolete comments about cc bombing out.
12376 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

12595 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
12596 Mark as externally visible.
12597 * dispnew.c (check_window_matrix_pointers): Now static.
12598 * dispnew.c (window_to_frame_vpos):
12599 * xfns.c (unwind_create_frame):
12600 * xterm.c (x_check_font): Remove unused local.
12601 * scroll.c (CHECK_BOUNDS):
12602 * xfaces.c (cache_fache): Rename local to avoid shadowing.
12603 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
12604 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
12605 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
12606 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
12608 (debug_method_add): Use va_list and vsprintf rather than relying
12609 on undefined behavior with wrong number of arguments.
12610 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12611 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12612 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12613 since we're not interested in debugging glyphs with old libraries.
12614 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12615 GCC 4.6.0's static checking.
12617 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12619 Integer overflow and signedness fixes (Bug#8873).
12620 A few related buffer overrun fixes, too.

12628 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
12629 (x_create_bitmap_from_xpm_data):
12630 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
12631 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
12633 * xfaces.c (load_pixmap):
12634 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
12635 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
12636 (.bitmaps_last, struct x_output.icon_bitmap):
12637 Use ptrdiff_t, not int, for bitmap indexes.
12638 (x_allocate_bitmap_record): Check for size overflow.
12639 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
12641 Use ptrdiff_t, not int, for overlay counts.
12642 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
12643 * editfns.c (overlays_around, get_pos_property):
12644 * textprop.c (get_char_property_and_overlay):
12645 * xdisp.c (next_overlay_change, note_mouse_highlight):
12646 * xfaces.c (face_at_buffer_position):
12647 * buffer.c (OVERLAY_COUNT_MAX): New macro.
12648 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
12649 (Fnext_overlay_change, Fprevious_overlay_change)
12650 (mouse_face_overlay_overlaps, Foverlays_in):
12651 Use ptrdiff_t, not int, for sizes.
12652 (overlays_at, overlays_in): Check for size-calculation overflow.
12654 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
12656 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
12657 (x_session_initialize): Do not assume string length fits in int.
12659 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
12660 This is unlikely, but can occur if DPI is outlandish.
12662 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
12663 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
12665 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
12666 * xrdb.c (magic_file_p, search_magic_path):
12667 Omit last arg SUFFIX; it was always 0. All callers changed.
12668 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
12670 * xfont.c (xfont_match): Avoid need for strlen.
12672 * xfns.c: Don't assume strlen fits in int.
12673 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
12675 * xdisp.c (message_log_check_duplicate): Return intmax_t,
12676 not unsigned long, as we prefer signed integers. All callers changed.
12677 Detect integer overflow in repeat count.
12678 (message_dolog): Don't assume print length fits in 39 bytes.
12679 (display_mode_element): Don't assume strlen fits in int.
12681 * termcap.c: Don't assume sizes fit in int and never overflow.
12682 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
12683 (gobble_line): Check for size-calculation overflow.
12685 * minibuf.c (Fread_buffer):
12686 * lread.c (intern, intern_c_string):
12687 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
12688 Don't assume string length fits in int.
12690 * keyboard.c (parse_tool_bar_item):
12691 * gtkutil.c (style_changed_cb): Avoid need for strlen.
12693 * font.c: Don't assume string length fits in int.
12694 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
12695 Use ptrdiff_t, not int.
12696 (font_intern_prop): Don't assume string length fits in int.
12697 Don't assume integer property fits in fixnum.
12698 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
12700 * filelock.c: Fix some buffer overrun and integer overflow issues.
12701 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
12702 Reformulate so as not to need the command string.
12703 Invoke gzip -cd rather than gunzip, as it's more portable.
12704 (lock_info_type, lock_file_1, lock_file):
12705 Don't assume pid_t and time_t fit in unsigned long.
12706 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
12707 (current_lock_owner): Prefer signed type for sizes.
12708 Use memcpy, not strncpy, where memcpy is what is really wanted.
12709 Don't assume (via atoi) that time_t and pid_t fit in int.
12710 Check for time_t and/or pid_t out of range, e.g., via a network share.
12711 Don't alloca where an auto var works fine.
12713 * fileio.c: Fix some integer overflow issues.
12714 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
12715 Don't assume string length fits in int.
12716 (directory_file_name): Don't assume string length fits in long.
12717 (make_temp_name): Don't assume pid fits in int, or that its print
12718 length is less than 20.
12720 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
12722 * coding.c (make_subsidiaries): Don't assume string length fits in int.
12724 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
12726 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
12727 We prefer signed integers, even for size calculations.
12729 * emacs.c: Don't assume string length fits in 'int'.
12730 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
12731 (main): Don't invoke strlen when not needed.
12733 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
12734 (XD_DEBUG_MESSAGE): Don't waste a byte.
12736 * callproc.c (getenv_internal_1, getenv_internal)
12737 (Fgetenv_internal):
12738 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
12740 * lread.c (invalid_syntax): Omit length argument.
12741 All uses changed. This doesn't fix a bug, but it simplifies the
12742 code away from its former Hollerith-constant appearance, and it's
12743 one less 'int' to worry about when looking at integer-overflow issues.
12744 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
12746 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
12747 This didn't break anything, but it didn't help either.
12748 It's confusing to put a bogus integer in a place where the actual
12749 value does not matter.
12750 (LIST_END_P): Remove unused macro and its bogus comment.
12751 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
12753 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
12754 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
12756 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
12757 We prefer signed types, and the value cannot exceed the EMACS_INT
12758 range anyway (because otherwise the length would not be representable).
12759 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
12760 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
12761 This avoids a GCC warning when WIDE_EMACS_INT.
12763 * indent.c (sane_tab_width): New function.
12764 (current_column, scan_for_column, Findent_to, position_indentation)
12765 (compute_motion): Use it. This is just for clarity.
12766 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
12768 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
12770 * lisp.h (lint_assume): New macro.
12771 * composite.c (composition_gstring_put_cache):
12772 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
12774 * editfns.c, insdel.c:
12775 Omit unnecessary forward decls, to simplify future changes.
12777 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
12779 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
12781 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
12782 Use much-faster test for byte-length change.
12783 Don't assume string byte-length fits in 'int'.
12784 Check that character arg fits in 'int'.
12785 (mapcar1): Declare byte as byte, for clarity.
12787 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
12789 * fns.c (concat): Catch string overflow earlier.
12790 Do not rely on integer wraparound.
12792 * dispextern.h (struct it.overlay_strings_charpos)
12793 (struct it.selective): Now EMACS_INT, not int.
12794 * xdisp.c (forward_to_next_line_start)
12795 (back_to_previous_visible_line_start)
12796 (reseat_at_next_visible_line_start, next_element_from_buffer):
12797 Don't arbitrarily truncate the value of 'selective' to int.
12799 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
12801 * composite.c: Don't truncate sizes to 'int'.
12802 (composition_gstring_p, composition_reseat_it)
12803 (composition_adjust_point): Use EMACS_INT, not int.
12804 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
12805 not EMACS_UINT, for indexes.
12807 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
12809 * buffer.c: Include <verify.h>.
12810 (struct sortvec.priority, struct sortstr.priority):
12811 Now EMACS_INT, not int.
12812 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
12813 (struct sortstr.size, record_overlay_string)
12814 (struct sortstrlist.size, struct sortlist.used):
12815 Don't truncate size to int.
12816 (record_overlay_string): Check for size-calculation overflow.
12817 (init_buffer_once): Check at compile-time, not run-time.
12819 2011-06-22 Jim Meyering <meyering@redhat.com>
12821 Don't leak an XBM-image-sized buffer
12822 * image.c (xbm_load): Free the image buffer after using it.
12824 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
12827 * composite.c (find_automatic_composition): Omit needless 'return 0;'
12828 that Sun C diagnosed.
12829 * fns.c (secure_hash): Fix pointer signedness issue.
12830 * intervals.c (static_offset_intervals): New function.
12831 (offset_intervals): Use it.
12833 2011-06-21 Leo Liu <sdl.web@gmail.com>
12836 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
12839 * fns.c (secure_hash): Rename from crypto_hash_function and change
12840 the first arg to accept symbols.
12841 (Fsecure_hash): New primitive.
12842 (syms_of_fns): New symbols.
12844 2011-06-20 Deniz Dogan <deniz@dogan.se>
12846 * process.c (Fset_process_buffer): Clarify return value in
12849 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
12851 * dispnew.c (add_window_display_history): Use BVAR.
12853 * xdisp.c (debug_method_add): Use BVAR.
12854 (check_window_end, dump_glyph_matrix, dump_glyph)
12855 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
12857 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
12860 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
12861 check till after the cache is created in init_frame_faces.
12863 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
12865 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
12867 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
12869 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
12870 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
12871 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
12873 Improve buffer-overflow checking (Bug#8873).
12874 * fileio.c (Finsert_file_contents):
12875 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
12876 Remove the old (too-loose) buffer overflow checks.
12877 They weren't needed, since make_gap checks for buffer overflow.
12878 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
12879 The old code merely checked for Emacs fixnum overflow, and relied
12880 on undefined (wraparound) behavior. The new code avoids undefined
12881 behavior, and also checks for ptrdiff_t and/or size_t overflow.
12883 * editfns.c (Finsert_char): Don't dump core with very negative counts.
12884 Tune. Don't use wider integers than needed. Don't use alloca.
12885 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
12887 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
12889 * insdel.c, lisp.h (buffer_overflow): New function.
12890 (insert_from_buffer_1, replace_range, replace_range_2):
12891 * insdel.c (make_gap_larger):
12892 * editfns.c (Finsert_char):
12893 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
12895 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
12897 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
12899 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
12901 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
12902 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
12904 * fileio.c: Don't assume EMACS_INT fits in off_t.
12905 (emacs_lseek): New static function.
12906 (Finsert_file_contents, Fwrite_region): Use it.
12907 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
12909 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
12911 * fns.c: Don't overflow int when computing a list length.
12912 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
12913 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
12914 truncation on 64-bit hosts. Check for QUIT every
12915 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
12916 faster and is responsive enough.
12917 (Flength): Report an error instead of overflowing an integer.
12918 (Fsafe_length): Return a float if the value is not representable
12919 as a fixnum. This shouldn't happen except in contrived situations.
12920 (Fnthcdr, Fsort): Don't assume list length fits in int.
12921 (Fcopy_sequence): Don't assume vector length fits in int.
12923 * alloc.c: Check that resized vectors' lengths fit in fixnums.
12924 (header_size, word_size): New constants.
12925 (allocate_vectorlike): Don't check size overflow here.
12926 (allocate_vector): Check it here instead, since this is the only
12927 caller of allocate_vectorlike that could cause overflow.
12928 Check that the new vector's length is representable as a fixnum.
12930 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
12931 The previous code was bogus. For example, next_almost_prime (32)
12932 returned 39, which is undesirable as it is a multiple of 3; and
12933 next_almost_prime (24) returned 25, which is a multiple of 5 so
12934 why was the code bothering to check for multiples of 7?
12936 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
12938 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
12940 Variadic C functions now count arguments with ptrdiff_t.
12941 This partly undoes my 2011-03-30 change, which replaced int with size_t.
12942 Back then I didn't know that the Emacs coding style prefers signed int.
12943 Also, in the meantime I found a few more instances where arguments
12944 were being counted with int, which may truncate counts on 64-bit
12945 machines, or EMACS_INT, which may be unnecessarily wide.
12946 * lisp.h (struct Lisp_Subr.function.aMANY)
12947 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
12948 Arg counts are now ptrdiff_t, not size_t.
12949 All variadic functions and their callers changed accordingly.
12950 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
12951 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
12952 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
12953 * callint.c (Fcall_interactively): Check arg count for overflow,
12954 to avoid potential buffer overrun. Use signed char, not 'int',
12955 for 'varies' array, so that we needn't bother to check its size
12956 calculation for overflow.
12957 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
12958 * eval.c (apply_lambda):
12959 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
12960 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
12961 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
12963 * callint.c (Fcall_interactively): Don't use index var as event count.
12965 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
12966 * mem-limits.h (SIZE): Remove; no longer used.
12968 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
12970 Remove unnecessary casts.
12971 * xterm.c (x_term_init):
12972 * xfns.c (x_set_border_pixel):
12973 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
12974 These aren't needed now that we assume ANSI C.
12976 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
12977 It's more likely to cause problems (due to unsigned overflow)
12980 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
12982 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
12984 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
12986 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
12988 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
12990 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
12992 GLYPH_CODE_FACE returns EMACS_INT, not int.
12993 * dispextern.h (merge_faces):
12994 * xfaces.c (merge_faces):
12995 * xdisp.c (get_next_display_element, next_element_from_display_vector):
12996 Don't assume EMACS_INT fits in int.
12998 * character.h (CHAR_VALID_P): Remove unused parameter.
12999 * fontset.c, lisp.h, xdisp.c: All uses changed.
13001 * editfns.c (Ftranslate_region_internal): Omit redundant test.
13003 * fns.c (concat): Minor tuning based on overflow analysis.
13004 This doesn't fix any bugs. Use int to hold character, instead
13005 of constantly refetching from Emacs object. Use XFASTINT, not
13006 XINT, for value known to be a character. Don't bother comparing
13007 a single byte to 0400, as it's always less.
13009 * floatfns.c (Fexpt):
13010 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
13012 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
13015 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
13017 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
13018 Without this fix, on a 64-bit host (aset S 0 4294967386) would
13019 incorrectly succeed when S was a string, because 4294967386 was
13020 truncated before it was used.
13022 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13023 Otherwise, an out-of-range integer could cause undefined behavior
13026 * composite.c: Use int, not EMACS_INT, for characters.
13027 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13028 EMACS_INT, for values that are known to be in character range.
13029 This doesn't fix any bugs but is the usual style inside Emacs and
13030 may generate better code on 32-bit machines.
13032 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13033 This is for reasons similar to the recent CHAR_STRING fix.
13034 * charset.c (Fencode_char): Check that character arg is actually
13035 a character. Pass an int to ENCODE_CHAR.
13036 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13037 wider than 'int', as a compile-time check to prevent future regressions
13040 * character.c (char_string): Remove unnecessary casts.
13042 Make sure a 64-bit char is never passed to CHAR_STRING.
13043 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13044 by silently ignoring the top 32 bits, allowing some values
13045 that were far too large to be valid characters.
13046 * character.h: Include <verify.h>.
13047 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13048 arguments are no wider than unsigned, as a compile-time check
13049 to prevent future regressions in this area.
13051 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
13052 (Fsubst_char_in_region):
13054 * xdisp.c (decode_mode_spec_coding):
13055 Adjust to CHAR_STRING's new requirement.
13056 * editfns.c (Finsert_char, Fsubst_char_in_region):
13057 * fns.c (concat): Check that character args are actually
13058 characters. Without this test, these functions did the wrong
13059 thing with wildly out-of-range values on 64-bit hosts.
13061 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13062 These casts should not be needed on 32-bit hosts, either.
13063 * keyboard.c (read_char):
13064 * lread.c (Fload): Remove casts to unsigned.
13066 * lisp.h (UNSIGNED_CMP): New macro.
13067 This fixes comparison bugs on 64-bit hosts.
13068 (ASCII_CHAR_P): Use it.
13069 * casefiddle.c (casify_object):
13070 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
13071 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
13072 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
13073 * dispextern.h (FACE_FROM_ID):
13074 * keyboard.c (read_char): Use UNSIGNED_CMP.
13076 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
13077 not to EMACS_INT, to avoid GCC warning.
13079 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13081 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13082 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
13083 isn't needed on 32-bit machines.
13085 * buffer.c (Fgenerate_new_buffer_name):
13086 Use EMACS_INT for count, not int.
13087 (advance_to_char_boundary): Return EMACS_INT, not int.
13089 * data.c (Qcompiled_function): Now static.
13091 * window.c (window_body_lines): Now static.
13093 * image.c (gif_load): Rename local to avoid shadowing.
13095 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
13096 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
13097 * alloc.c (make_save_value): Integer argument is now of type
13098 ptrdiff_t, not int.
13099 (mark_object): Use ptrdiff_t, not int.
13100 * lisp.h (pD): New macro.
13101 * print.c (print_object): Use it.
13103 * alloc.c: Use EMACS_INT, not int, to count objects.
13104 (total_conses, total_markers, total_symbols, total_vector_size)
13105 (total_free_conses, total_free_markers, total_free_symbols)
13106 (total_free_floats, total_floats, total_free_intervals)
13107 (total_intervals, total_strings, total_free_strings):
13108 Now EMACS_INT, not int. All uses changed.
13109 (Fgarbage_collect): Compute overall total using a double, so that
13110 integer overflow is less likely to be a problem. Check for overflow
13111 when converting back to an integer.
13112 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
13113 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
13114 These were 'int' variables that could overflow on 64-bit hosts;
13115 they were never used, so remove them instead of repairing them.
13116 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
13117 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
13118 Previously, this ceilinged at INT_MAX, but that doesn't work on
13120 (allocate_pseudovector): Don't use EMACS_INT when int would do.
13122 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
13123 (allocate_vectorlike): Check for ptrdiff_t overflow.
13124 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13125 when a (possibly-narrower) signed value would do just as well.
13126 We prefer using signed arithmetic, to avoid comparison confusion.
13128 * alloc.c: Catch some string size overflows that we were missing.
13129 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
13130 for convenience in STRING_BYTES_MAX.
13131 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
13132 The definition here is exact; the one in lisp.h was approximate.
13133 (allocate_string_data): Check for string overflow. This catches
13134 some instances we weren't catching before. Also, it catches
13135 size_t overflow on (unusual) hosts where SIZE_MAX <= min
13136 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
13137 and ptrdiff_t and EMACS_INT are both 64 bits.
13139 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
13140 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
13141 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
13143 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
13145 * alloc.c (Fmake_string): Check for out-of-range init.
13147 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
13149 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
13151 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
13153 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

13164 and height if HAVE_GTK3 (Bug#8505).
13165 (scroll_bar_width_for_theme): New variable.
13166 (update_theme_scrollbar_width): New function.
13167 (xg_get_default_scrollbar_width): Move code to

13171 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
13173 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

13177 * frame.c (make_frame): Call other_buffer_safely instead of
13180 * window.c (temp_output_buffer_show): Call display_buffer with
13181 second argument Vtemp_buffer_show_specifiers and reset latter
13182 immediately after the call.
13183 (Vtemp_buffer_show_specifiers): New variable.
13184 (auto_window_vscroll_p, next_screen_context_lines)
13185 (Vscroll_preserve_screen_position): Remove leading asterisks from

13718 instead of using explicit *_CHAR codes.
13719 (bidi_resolve_explicit, bidi_resolve_weak):

13728 (bidi_level_of_next_char): Don't try to lookup the cache for the
13729 next/previous character if nothing is cached there yet, or if we
13730 were just reseat()'ed to a new position.
13732 * xdisp.c (set_cursor_from_row): Set start and stop points
13733 according to the row's direction when priming the loop that looks
13734 for the glyph on which to display cursor.

13736 (display_prop_intangible_p): Reimplement to call
13737 handle_display_spec instead of single_display_spec_intangible_p.

13748 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
13749 value of a `display' property is a "replacing spec".
13750 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
13751 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
13752 the display property, but just return a value indicating whether
13753 the display property will replace the characters it covers.
13754 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
13755 frame_window_p members of struct bidi_it.

13781 * gnutls.c: Use Emacs's memory allocators.
13782 Without this change, the gnutls library would invoke malloc etc.
13783 directly, which causes problems on non-SYNC_INPUT hosts, and which
13784 runs afoul of improving memory_full behavior. (Bug#8761)
13785 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
13786 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
13787 xfree instead of the default malloc, realloc, free.
13788 (Fgnutls_boot): No need to check for memory allocation failure,
13789 since xmalloc does that for us.

13818 need to be updated by these changes.
13819 * fns.c (make_hash_table, maybe_resize_hash_table):
13820 Check for integer overflow with large hash tables.
13821 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
13822 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
13823 (SXHASH_REDUCE): New macro.
13824 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
13825 Use it instead of discarding useful hash info with large hash values.
13826 (sxhash_float): New function.
13827 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
13828 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
13829 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
13830 Rewrite to use FIXNUM_BITS, as this simplifies things.
13831 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
13832 Adjust signatures to match updated version of code.
13833 (consing_since_gc): Now EMACS_INT, since a single hash table can
13834 use more than INT_MAX bytes.

13883 Make it possible to run ./temacs.
13885 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
13886 syms_of_callproc does the same thing. Remove test for

13895 (Qmetadata): New var.
13896 * data.c (Qbuffer): Don't make it static.
13897 (syms_of_data): Use DEFSYM.
13899 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
13901 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
13902 (CCL_CODE_MIN): New macro.
13904 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
13906 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
13908 * eval.c (Qdebug): Now static.
13909 * lisp.h (Qdebug): Remove decl. This reverts a part of the
13910 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
13911 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
13913 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
13915 * image.c: Various fixes to ImageMagick code comments.
13916 (Fimagemagick_types): Doc fix.
13918 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
13920 Minor fixes prompted by GCC 4.6.0 warnings.
13922 * xselect.c (converted_selections, conversion_fail_tag): Now static.
13924 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
13925 (x_clipboard_manager_save_all): Move extern decl to ...
13926 * xterm.h: ... here, so that it can be checked for consistency.
13928 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
13930 * xselect.c (x_clipboard_manager_save_frame)
13931 (x_clipboard_manager_save_all): New functions.
13932 (Fx_clipboard_manager_save): Lisp function deleted.
13934 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
13935 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
13937 * xterm.h: Update prototype.
13939 2011-05-28 William Xu <william.xwl@gmail.com>
13941 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
13942 exiting (Bug#8239).
13944 2011-05-28 Jim Meyering <meyering@redhat.com>
13946 Avoid a sign-extension bug in crypto_hash_function.
13947 * fns.c (to_uchar): Define.
13948 (crypto_hash_function): Use it to convert some newly-signed
13949 variables to unsigned, to avoid sign-extension bugs. For example,
13950 without this change, (md5 "truc") would evaluate to
13951 45723a2aff78ff4fff7fff1114760e62 rather than the expected
13952 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
13953 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
13955 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13957 Integer overflow fixes.
13959 * dbusbind.c: Serial number integer overflow fixes.
13960 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
13961 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
13962 to hold a serial number that is too large for a fixnum.
13963 (Fdbus_method_return_internal, Fdbus_method_error_internal):
13964 Check for serial numbers out of range. Decode any serial number
13965 that was so large that it became a float. (Bug#8722)
13967 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
13968 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13969 Use XFASTINT rather than XUINT when numbers are nonnegative.
13970 (xd_append_arg, Fdbus_method_return_internal):
13971 (Fdbus_method_error_internal): Likewise. Also, for unsigned
13972 arguments, check that Lisp number is nonnegative, rather than
13973 silently wrapping negative numbers around. (Bug#8722)
13974 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
13977 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
13979 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
13981 ccl: Add integer overflow checks.
13982 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
13983 (IN_INT_RANGE): New macros.
13984 (ccl_driver): Use them to check for integer overflow when
13985 decoding a CCL program. Many of the new checks are whether XINT (x)
13986 fits in int; it doesn't always, on 64-bit hosts. The new version
13987 doesn't catch all possible integer overflows, but it's an
13988 improvement. (Bug#8719)
13990 * alloc.c (make_event_array): Use XINT, not XUINT.
13991 There's no need for unsigned here.
13993 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
13994 This follows up to the 2011-05-06 change that substituted uintptr_t
13995 for EMACS_INT. This case wasn't caught back then.
13997 Rework Fformat to avoid integer overflow issues.
13998 * editfns.c: Include <float.h> unconditionally, as it's everywhere
13999 now (part of C89). Include <verify.h>.
14000 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
14001 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
14002 (Fformat): Avoid the prepass trying to compute sizes; it was only
14003 approximate and thus did not catch overflow reliably. Instead, walk
14004 through the format just once, formatting and computing sizes as we go,
14005 checking for integer overflow at every step, and allocating a larger
14006 buffer as needed. Keep track separately whether the format is
14007 multibyte. Keep only the most-recently calculated precision, rather
14008 than them all. Record whether each argument has been converted to
14009 string. Use EMACS_INT, not int, for byte and char and arg counts.
14010 Support field widths and precisions larger than INT_MAX. Avoid
14011 sprintf's undefined behavior with conversion specifications such as %#d
14012 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
14013 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
14014 formatting out-of-range floating point numbers with int
14015 formats. (Bug#8668)
14017 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
14019 * data.c: Avoid integer truncation in expressions involving floats.
14020 * data.c: Include <intprops.h>.
14021 (arith_driver): When there's an integer overflow in an expression
14022 involving floating point, convert the integers to floating point
14023 so that the resulting value does not suffer from catastrophic
14024 integer truncation. For example, on a 64-bit host (* 4
14025 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14026 Do not rely on undefined behavior after integer overflow.
14028 merge count_size_as_multibyte, parse_str_to_multibyte
14029 * character.c, character.h (count_size_as_multibyte):
14030 Rename from parse_str_to_multibyte; all uses changed.
14031 Check for integer overflow.
14032 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14033 since it's now a duplicate of the other. This is more of
14034 a character than a buffer op, so better that it's in character.c.
14035 * fns.c, print.c: Adjust to above changes.
14037 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14039 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14041 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14043 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14044 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14045 (x_clipboard_manager_save): Now static.
14046 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14048 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14049 (crypto_hash_function): Now static.
14050 Fix pointer signedness problems. Avoid unnecessary initializations.
14052 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14054 * termhooks.h (Vselection_alist): Make it terminal-local.
14056 * terminal.c (create_terminal): Initialize it.
14058 * xselect.c: Support for clipboard managers.
14059 (Vselection_alist): Move to termhooks.h as terminal-local var.
14060 (LOCAL_SELECTION): New macro.
14061 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14062 (symbol_to_x_atom): Remove gratuitous arg.
14063 (x_handle_selection_request, lisp_data_to_selection_data)
14064 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14065 (x_own_selection, x_get_local_selection, x_convert_selection):
14066 New arg, specifying work frame. Use terminal-local Vselection_alist.
14067 (some_frame_on_display): Delete unused function.
14068 (Fx_own_selection_internal, Fx_get_selection_internal)
14069 (Fx_disown_selection_internal, Fx_selection_owner_p)
14070 (Fx_selection_exists_p): New optional frame arg.
14071 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14072 (x_handle_selection_clear): Don't treat other terminals with the
14073 same keyboard specially. Use the terminal-local Vselection_alist.
14074 (x_clear_frame_selections): Use Frun_hook_with_args.
14076 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14078 * xterm.h: Add support for those atoms.
14080 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14082 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14083 (converted_selections, conversion_fail_tag): New global variables.
14084 (x_selection_request_lisp_error): Free the above.
14085 (x_get_local_selection): Remove unnecessary code.
14086 (x_reply_selection_request): Args changed; handle arbitrary array
14087 of converted selections stored in converted_selections.
14088 Separate the XChangeProperty and SelectionNotify steps.
14089 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14090 (x_convert_selection): New function.
14091 (x_handle_selection_event): Simplify.
14092 (x_get_foreign_selection): Don't ignore incoming requests while
14093 waiting for an answer; this will fail when we implement
14094 SAVE_TARGETS, and seems unnecessary anyway.
14095 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14096 (Vx_sent_selection_functions): Doc fix.
14098 2011-05-26 Leo Liu <sdl.web@gmail.com>
14100 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14102 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14104 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14106 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14107 for fringe update if it has periodic bitmap.
14108 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14109 and fringe_bitmap_periodic_p.
14111 * fringe.c (get_fringe_bitmap_data): New function.
14112 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14113 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14114 row. Mark glyph row for fringe update if periodicity changed.
14116 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14117 for fringe update unless it has periodic bitmap.
14119 2011-05-25 Kenichi Handa <handa@m17n.org>
14121 * xdisp.c (get_next_display_element): Set correct it->face_id for
14122 a static composition.
14124 2011-05-24 Leo Liu <sdl.web@gmail.com>
14127 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
14129 * fns.c (crypto_hash_function, Fsha1): New function.
14130 (Fmd5): Use crypto_hash_function.
14131 (syms_of_fns): Add Ssha1.
14133 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14135 * gnutls.c: Remove unused macros.
14136 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14137 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14138 Remove macros that are defined and never used.
14139 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14141 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14143 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14144 (Fx_get_selection_internal): Minor cleanup.
14145 (Fx_own_selection_internal): Rename arguments for consistency with
14148 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14150 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
14152 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14154 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
14156 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14158 * dispnew.c (scrolling_window): Don't exclude the case that the
14159 last enabled row in the desired matrix touches the bottom boundary.
14161 2011-05-21 Glenn Morris <rgm@gnu.org>
14163 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
14164 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
14165 and add some more files.
14167 2011-05-20 Eli Zaretskii <eliz@gnu.org>
14169 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
14170 report_file_error introduced by the change from 2011-05-07.
14172 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14174 * systime.h (Time): Define only if emacs is defined.
14175 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14176 where the include path doesn't have X11/X.h by default. See
14177 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14179 2011-05-20 Kenichi Handa <handa@m17n.org>
14181 * composite.c (find_automatic_composition): Fix previous change.
14183 2011-05-20 Glenn Morris <rgm@gnu.org>
14185 * lisp.mk: New file, split from Makefile.in.
14186 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14187 (shortlisp): Remove.
14188 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14190 2011-05-19 Glenn Morris <rgm@gnu.org>
14192 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14193 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14194 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14195 (lisp): Set the order to that of loadup.el.
14196 (shortlisp): Make it a copy of $lisp.
14197 (SOME_MACHINE_LISP): Remove.
14198 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14199 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14201 2011-05-18 Kenichi Handa <handa@m17n.org>
14203 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14204 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14205 (find_automatic_composition): Mostly rewrite for efficiency.
14207 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14209 * makefile.w32-in: Update dependencies.
14211 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14213 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14214 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14216 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14218 Fix some integer overflow issues, such as string length overflow.
14220 * insdel.c (count_size_as_multibyte): Check for string overflow.
14222 * character.c (lisp_string_width): Check for string overflow.
14223 Use EMACS_INT, not int, for string indexes and lengths; in
14224 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14225 the resulting string length overflows an EMACS_INT; instead,
14226 report a string overflow if no precision given. When checking for
14227 precision exhaustion, use a check that cannot possibly have
14228 integer overflow. (Bug#8675)
14229 * character.h (lisp_string_width): Adjust to new signature.
14231 * alloc.c (string_overflow): New function.
14232 (Fmake_string): Use it. This doesn't change behavior, but saves
14233 a few bytes and will simplify future changes.
14234 * character.c (string_escape_byte8): Likewise.
14235 * lisp.h (string_overflow): New decl.
14237 Fixups, following up to the user-interface timestamp change.
14238 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14239 for UI timestamps, instead of unsigned long.
14240 * msdos.c (mouse_get_pos): Likewise.
14241 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14242 * w32gui.h (Time): Define by including "systime.h" rather than by
14243 declaring it ourselves. (Bug#8664)
14245 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14246 * image.c (clear_image_cache): Likewise.
14248 * term.c (term_mouse_position): Don't assume time_t wraparound.
14250 Be more systematic about user-interface timestamps.
14251 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14252 and sometimes 'EMACS_UINT', to represent these timestamps.
14253 This change causes it to use 'Time' uniformly, as that's what X uses.
14254 This makes the code easier to follow, and makes it easier to catch
14255 integer overflow bugs such as Bug#8664.
14256 * frame.c (Fmouse_position, Fmouse_pixel_position):
14257 Use Time, not unsigned long, for user-interface timestamps.
14258 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14259 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14260 * keyboard.h (last_event_timestamp): Likewise.
14261 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14262 * menu.h (xmenu_show): Likewise.
14263 * term.c (term_mouse_position): Likewise.
14264 * termhooks.h (struct input_event.timestamp): Likewise.
14265 (struct terminal.mouse_position_hook): Likewise.
14266 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14267 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14268 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14269 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14270 what it was before.
14271 * menu.h, termhooks.h: Include "systime.h", for Time.
14273 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14274 Don't assume that the difference between two unsigned long values
14275 can fit into an integer. At this point, we know button_down_time
14276 <= event->timestamp, so the difference must be nonnegative, so
14277 there's no need to cast the result if double-click-time is
14278 nonnegative, as it should be; check that it's nonnegative, just in
14279 case. This bug is triggered when events are more than 2**31 ms
14280 apart (about 25 days). (Bug#8664)
14282 * xselect.c (last_event_timestamp): Remove duplicate decl.
14283 (x_own_selection): Remove needless cast to unsigned long.
14285 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14286 that always fit in int. Use a sentinel instead of a counter, to
14287 avoid a temp and to allay GCC's concerns about possible int overflow.
14288 * frame.h (struct frame): Use int for menu_bar_items_used
14289 instead of EMACS_INT, since it always fits in int.
14291 * menu.c (grow_menu_items): Check for int overflow.
14293 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14295 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14296 Before, the code was not consistent. These values cannot exceed
14297 2**31 - 1 so there's no need to make them unsigned.
14298 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14299 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14300 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14302 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14304 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14305 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14306 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14307 presumably because the widths might not match.
14309 * window.c (size_window): Avoid needless test at loop start.
14311 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14313 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14315 2011-05-12 Drew Adams <drew.adams@oracle.com>
14317 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14319 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14321 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14322 `width' to `bar_area_x' and `bar_area_width', respectively.
14323 (x_scroll_run): Take account of fringe background extension.
14325 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14326 Rename local vars `left' and `width' to `bar_area_x' and
14327 `bar_area_width', respectively.
14328 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14329 background extension.
14331 2011-05-10 Jim Meyering <meyering@redhat.com>
14333 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14335 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14337 * image.c (Finit_image_library): Return t for built-in image types,
14338 like pbm and xbm. (Bug#8640)
14340 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14342 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14344 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14346 * w32console.c (Fset_screen_color): Doc fix.
14347 (Fget_screen_color): New function.
14348 (syms_of_ntterm): Defsubr it.
14350 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14351 unlink the temporary file if Fcall_process didn't create it in the
14353 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14354 child process will be redirected to a file specified with `:file'.
14355 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14356 cue to call_process_cleanup not to close that handle.
14358 2011-05-07 Ben Key <bkey76@gmail.com>
14360 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14361 one of two shell specific rules, either bootstrap-temacs-CMD or
14362 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14363 to the previous implementation of the bootstrap-temacs rule.
14364 The bootstrap-temacs-CMD rule is similar to the previous
14365 implementation of the bootstrap-temacs rule except that it
14366 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14369 These changes, along with some changes to nt/configure.bat,
14370 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14371 earlier fix to add support for --cflags and --ldflags options
14372 that include quotes so that it works whether make uses cmd or
14375 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14377 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14378 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14380 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14381 a string. Handle both cases.
14382 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14383 (Fdbus_register_method): Use Qinvalid_function.
14385 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14387 * makefile.w32-in: Update dependencies.
14388 (LISP_H): Add inttypes.h and stdin.h.
14389 (PROCESS_H): Add unistd.h.
14391 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14393 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14394 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14396 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14398 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14400 * term.c (vfatal): Remove stray call to va_end.
14401 It's not needed and the C Standard doesn't allow it here anyway.
14403 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14404 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14406 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14409 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14411 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14413 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14415 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14417 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14419 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14420 * charset.c (Fdefine_charset_internal): Don't initialize
14421 charset.code_space[15]. The value was garbage, on hosts with
14422 32-bit int (Bug#8600).
14424 * lread.c (read_integer): Be more consistent with string-to-number.
14425 Use string_to_number to do the actual conversion; this avoids
14426 rounding errors and fixes some other screwups. Without this fix,
14427 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14428 (digit_to_number): Move earlier, for benefit of read_integer.
14429 Return -1 if the digit is out of range for the base, -2 if it is
14430 not a digit in any supported base. (Bug#8602)
14432 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14434 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14435 to match comment at start of function. This also removes a
14436 GCC warning about overflow in a 32+64-bit port.
14438 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14440 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14441 Reported by Stefan Monnier in
14442 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14443 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14444 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14446 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14447 (EMACS_UINTPTR): Likewise, with uintptr_t.
14449 * lisp.h: Prefer 64-bit EMACS_INT if available.
14450 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14451 on 32-bit hosts that have 64-bit int, so that they can access
14453 However, temporarily disable this change unless the temporary
14454 symbol WIDE_EMACS_INT is defined.
14456 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14458 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14459 This removes an assumption that EMACS_INT and long are the same
14460 width as pointers. The assumption is true for Emacs porting targets
14461 now, but we want to make other targets possible.
14462 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14463 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14464 In the rest of the code, change types of integers that hold casted
14465 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14466 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14467 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14468 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14469 No need to cast type when ORing.
14470 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14471 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14472 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14473 assume EMACS_INT is the same width as char *.
14474 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14475 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14476 Remove no-longer-needed casts.
14477 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14478 (xg_tool_bar_help_callback, xg_make_tool_item):
14479 Use EMACS_INTPTR to hold an integer
14480 that will be cast to void *; this can avoid a GCC warning
14481 if EMACS_INT is not the same width as void *.
14482 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14483 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14484 (current_message_1, set_message_1):
14485 Use a local to convert to proper width without a cast.
14486 * xmenu.c (dialog_selection_callback): Likewise.
14488 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14489 Also, don't assume VALBITS / RAND_BITS is less than 5,
14490 and don't rely on undefined behavior when shifting a 1 left into
14492 * lisp.h (get_random): Change signature to match.
14494 * lread.c (hash_string): Use size_t, not int, for hash computation.
14495 Normally we prefer signed values; but hashing is special, because
14496 it's better to use unsigned division on hash table sizes so that
14497 the remainder is nonnegative. Also, size_t is the natural width
14498 for hashing into memory. The previous code used 'int', which doesn't
14499 retain enough info to hash well into very large tables.
14500 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14502 * dbusbind.c: Don't possibly lose pointer info when converting.
14503 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14504 Use XPNTR rather than XHASH, so that the high-order bits of
14505 the pointer aren't lost when converting through void *.
14507 * eval.c (Fautoload): Don't double-shift a pointer.
14509 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14511 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14513 * gnutls.c (DEF_GNUTLS_FN):
14514 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14516 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14518 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14521 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14523 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14524 New version that can reserve upto 2GB of heap space.
14526 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14528 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14530 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14532 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14533 `gnutls_certificate_set_x509_key_file'.
14535 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
14537 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
14538 Update dependencies.
14540 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14542 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14543 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14544 Remove unused parameter `fildes'.
14545 * process.c (read_process_output, send_process): Don't pass it.
14547 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14549 Fix previous change: the library cache is defined in w32.c.
14550 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14551 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14553 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14555 Implement dynamic loading of GnuTLS on Windows.
14557 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14558 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14559 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14562 * gnutls.c (Qgnutls_dll): Define.
14563 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
14564 (gnutls_*): Declare function pointers.
14565 (init_gnutls_functions): New function to initialize function pointers.

14568 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14569 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
14570 (emacs_gnutls_write, emacs_gnutls_read)
14571 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14572 (Fgnutls_available_p): New function.
14573 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
14574 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
14575 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
14577 * image.c: Include w32.h.
14578 (Vimage_type_cache): Delete.
14579 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
14580 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
14581 (w32_delayed_load): Move to w32.c.
14583 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
14585 * w32.c (QCloaded_from, Vlibrary_cache): Define.
14586 (w32_delayed_load): Move from image.c. When loading a library, record
14587 its filename in the :loaded-from property of the library id.
14588 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
14589 Initialize and staticpro them.
14590 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
14592 * process.c: Include lisp.h before w32.h, not after.
14593 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
14594 instead of gnutls_record_check_pending.
14596 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
14598 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
14600 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
14601 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
14604 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
14606 * xterm.c (x_set_frame_alpha): Do not set property on anything
14607 else than FRAME_X_OUTER_WINDOW (Bug#8608).
14609 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14611 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
14613 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14615 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

14629 * sysdep.c (wait_for_termination_1): Make static.
14630 (wait_for_termination, interruptible_wait_for_termination):
14631 Move after wait_for_termination_1.
14633 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
14635 * sysdep.c (interruptible_wait_for_termination): New function
14636 which is like wait_for_termination, but allows keyboard
14639 * callproc.c (Fcall_process): Add (:file "file") as an option for
14641 (Fcall_process_region): Ditto.
14643 2011-04-30 Eli Zaretskii <eliz@gnu.org>
14645 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
14646 rather than `XVECTOR (FOO)->size'.
14648 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
14649 inttypes.h, as a gnulib replacement is used if it not available in
14652 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14654 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
14655 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
14656 of MOST_POSITIVE_FIXNUM. (Bug#8528)
14658 * coding.c (coding_alloc_by_realloc): Error out if destination
14659 will grow beyond MOST_POSITIVE_FIXNUM.
14660 (decode_coding_emacs_mule): Abort if there isn't enough place in
14661 charbuf for the composition carryover bytes. Reserve an extra

14669 aborting when %lld or %lll format is passed.
14670 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
14671 %llo or %llx format is passed. (Bug#8545)
14673 * window.c (window_scroll_line_based): Use a marker instead of
14674 simple variables to record original value of point. (Bug#7952)
14676 * doprnt.c (doprnt): Fix the case where a multibyte sequence
14677 produced by %s or %c overflows available buffer space. (Bug#8545)
14679 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
14681 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
14682 (SIZE_MAX): Move defn after all includes, as they might #define it.
14684 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14686 * w32.c (init_environment): Warn about defaulting HOME to C:\.

14706 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14708 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
14710 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
14712 * makefile.w32-in: Update dependencies.
14714 2011-04-27 Eli Zaretskii <eliz@gnu.org>
14716 Improve `doprnt' and its usage. (Bug#8545)
14717 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
14718 `format_end'. Remove support for %l as a conversion specifier.
14719 Don't use xrealloc. Improve diagnostics when the %l size modifier
14720 is used. Update the commentary.
14722 * eval.c (verror): Simplify calculation of size_t.
14724 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
14727 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
14729 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
14732 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14734 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
14735 This makes this file independent of the recent pseudovector change.
14737 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
14739 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
14741 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
14742 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
14743 Remove unused local.
14744 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
14746 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
14747 GCC 4.6.0 optimizes based on type-based alias analysis.
14748 For example, if b is of type struct buffer * and v of type struct
14749 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
14750 != &v->size, and therefore "v->size = 1; b->size = 2; return
14751 v->size;" must therefore return 1. This assumption is incorrect
14752 for Emacs, since it type-puns struct Lisp_Vector * with many other
14753 types. To fix this problem, this patch adds a new type struct
14754 vectorlike_header that documents the constraints on layout of vectors
14755 and pseudovectors, and helps optimizing compilers not get fooled
14756 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
14757 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
14758 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
14760 (XSETPVECTYPE): Rewrite in terms of new macro.
14761 (XSETPVECTYPESIZE): New macro, specifying both type and size.
14762 This is a bit clearer, and further avoids the possibility of
14763 undesirable aliasing.
14764 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
14765 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
14766 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
14767 since Lisp_Subr is a special case (no "next" field).
14768 (ASIZE): Now uses header.size rather than size.
14769 All previous uses of XVECTOR (foo)->size replaced to use this macro,
14770 to avoid the hassle of writing XVECTOR (foo)->header.size.
14771 (struct vectorlike_header): New type.
14772 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
14773 object, to help avoid aliasing.
14774 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
14775 (SUBRP): Likewise, since Lisp_Subr is a special case.
14776 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
14777 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
14778 (struct Lisp_Hash_Table): Combine first two members into a single
14779 struct vectorlike_header member. All uses of "size" and "next" members
14780 changed to be "header.size" and "header.next".
14781 * buffer.h (struct buffer): Likewise.
14782 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
14783 * frame.h (struct frame): Likewise.
14784 * process.h (struct Lisp_Process): Likewise.
14785 * termhooks.h (struct terminal): Likewise.
14786 * window.c (struct save_window_data, struct saved_window): Likewise.
14787 * window.h (struct window): Likewise.
14788 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
14789 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
14790 * buffer.c (init_buffer_once): Likewise.
14791 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
14793 * process.c (Fformat_network_address): Use local var for size,
14796 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
14798 Make the Lisp reader and string-to-float more consistent (Bug#8525)
14799 * data.c (atof): Remove decl; no longer used or needed.
14800 (digit_to_number): Move to lread.c.
14801 (Fstring_to_number): Use new string_to_number function, to be
14802 consistent with how the Lisp reader treats infinities and NaNs.
14803 Do not assume that floating-point numbers represent EMACS_INT
14804 without losing information; this is not true on most 64-bit hosts.
14805 Avoid double-rounding errors, by insisting on integers when
14806 parsing non-base-10 numbers, as the documentation specifies.
14807 * lisp.h (string_to_number): New decl, replacing ...
14808 (isfloat_string): Remove.
14809 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
14810 (read1): Do not accept +. and -. as integers; this
14811 appears to have been a coding error. Similarly, do not accept
14812 strings like +-1e0 as floating point numbers. Do not report
14813 overflow for integer overflows unless the base is not 10 which
14814 means we have no simple and reliable way to continue.
14815 Break out the floating-point parsing into a new
14816 function string_to_number, so that Fstring_to_number parses
14817 floating point numbers consistently with the Lisp reader.
14818 (digit_to_number): Move here from data.c. Make it static inline.
14819 (E_CHAR, EXP_INT): Remove, replacing with ...
14820 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
14821 (string_to_number): New function, replacing isfloat_string.
14822 This function checks for valid syntax and produces the resulting
14823 Lisp float number too. Rework it so that string-to-number
14824 no longer mishandles examples like "1.0e+". Use strtoumax,
14825 so that overflow for non-base-10 numbers is reported only when
14826 there's no portable and simple way to convert to floating point.
14828 * textprop.c (set_text_properties_1): Rewrite for clarity,
14829 and to avoid GCC warning about integer overflow.
14831 * intervals.h (struct interval): Use EMACS_INT for members
14832 where EMACS_UINT might cause problems. See
14833 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
14834 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
14835 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
14837 (offset_intervals): Tell GCC not to worry about length overflow
14838 when negating a negative length.
14840 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
14841 (overrun_check_free): Likewise.
14843 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
14844 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
14847 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14848 (gnutls_make_error): Rename local to avoid shadowing.
14849 (gnutls_emacs_global_deinit): ifdef out; not used.
14850 (Fgnutls_boot): Use const for pointer to readonly storage.
14851 Comment out unused local. Fix pointer signedness problems.
14853 * lread.c (openp): Don't stuff size_t into an 'int'.
14854 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
14855 about possible signed overflow.
14857 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14858 (GDK_KEY_g): Don't define if already defined.
14859 (xg_prepare_tooltip): Avoid pointer signedness problem.
14860 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
14862 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
14863 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
14865 * xfns.c (Fx_window_property): Simplify a bit,
14866 to make a bit faster and to avoid GCC 4.6.0 warning.
14867 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
14869 * fns.c (internal_equal): Don't assume size_t fits in int.
14871 * alloc.c (compact_small_strings): Tighten assertion a little.
14873 Replace pEd with more-general pI, and fix some printf arg casts.
14874 * lisp.h (pI): New macro, generalizing old pEd macro to other
14875 conversion specifiers. For example, use "...%"pI"d..." rather
14876 than "...%"pEd"...".
14877 (pEd): Remove. All uses replaced with similar uses of pI.
14878 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
14879 * alloc.c (check_pure_size): Don't overflow by converting size to int.
14880 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
14881 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
14882 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
14883 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
14884 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
14886 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
14887 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
14888 * print.c (safe_debug_print, print_object): Likewise.
14889 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
14891 Use pI instead of if-then-else-abort. Use %p to avoid casts,
14892 avoiding the 0 flag, which is not portable.
14893 * process.c (Fmake_network_process): Use pI to avoid cast.
14894 * region-cache.c (pp_cache): Likewise.
14895 * xdisp.c (decode_mode_spec): Likewise.
14896 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
14897 behavior on 64-bit hosts with printf arg.
14898 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
14899 (x_stop_queuing_selection_requests): Likewise.
14900 (x_get_window_property): Don't truncate byte count to an 'int'
14903 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
14904 here, since it parses constructs like leading '-' and spaces,
14905 which are not wanted; and it overflows with large numbers.
14906 Instead, simply match F[0-9]+, which is what is wanted anyway.
14908 * alloc.c: Remove unportable assumptions about struct layout.
14909 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
14910 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
14911 (allocate_vectorlike, make_pure_vector): Use the new macros,
14912 plus offsetof, to remove unportable assumptions about struct layout.
14913 These assumptions hold on all porting targets that I know of, but
14914 they are not guaranteed, they're easy to remove, and removing them
14915 makes further changes easier.
14917 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
14918 This doesn't fix a bug but makes the code clearer.
14919 (string_overrun_cookie): Now const. Use initializers that
14920 don't formally overflow signed char, to avoid warnings.
14921 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
14922 can cause Emacs to crash when string overrun checking is enabled.
14923 (allocate_buffer): Don't assume sizeof (struct buffer) is a
14924 multiple of sizeof (EMACS_INT); it need not be, if
14925 alignof(EMACS_INT) < sizeof (EMACS_INT).
14926 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
14928 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

14934 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
14935 supposed to be handshaking. (Bug#8556)
14936 Reported by Paul Eggert <eggert@cs.ucla.edu>.
14938 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
14940 * lisp.h (Qdebug): List symbol.
14941 * eval.c (Qdebug): Restore global linkage.

14943 (handle_user_signal): Break into debugger when debug-on-event
14944 matches the current signal symbol.
14946 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
14948 * alloc.c (check_sblock, check_string_bytes)
14949 (check_string_free_list): Convert to standard C.
14951 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
14953 * w32.c (emacs_gnutls_push): Fix typo.
14955 2011-04-25 Eli Zaretskii <eliz@gnu.org>
14957 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
14958 "cast to pointer from integer of different size".
14960 Improve doprnt and its use in verror. (Bug#8545)
14961 * doprnt.c (doprnt): Document the set of format control sequences
14962 supported by the function. Use SAFE_ALLOCA instead of always
14965 * eval.c (verror): Don't limit the buffer size at size_max-1, that
14966 is one byte too soon. Don't use xrealloc; instead xfree and
14969 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
14971 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
14974 * gnutls.c: Renamed global_initialized to
14975 gnutls_global_initialized. Added internals for the
14976 :verify-hostname-error, :verify-error, and :verify-flags
14977 parameters of `gnutls-boot' and documented those parameters in the
14978 docstring. Start callback support.
14979 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
14980 unless a fatal error occurred. Call gnutls_alert_send_appropriate
14981 on error. Return error code.

14983 (emacs_gnutls_read): Likewise.
14984 (Fgnutls_boot): Return handshake error code.
14985 (emacs_gnutls_handle_error): New function.

15041 changes in globals.h immediately force recompilation.
15042 (TAGS): Depend on $(CURDIR)/m/intel386.h and
15043 $(CURDIR)/s/ms-w32.h.

15048 <char-direction-table>: Deleted.
15050 2011-04-23 Eli Zaretskii <eliz@gnu.org>
15052 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
15053 * doprnt.c: Include limits.h.
15054 (SIZE_MAX): New macro.
15055 (doprnt): Return a size_t value. 2nd arg is now size_t.
15056 Many local variables are now size_t instead of int or unsigned.
15057 Improve overflow protection. Support `l' modifier for integer
15058 conversions. Support %l conversion. Don't assume an EMACS_INT
15059 argument for integer conversions and for %c.
15061 * lisp.h (doprnt): Restore prototype.
15063 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
15064 $(SRC)/character.h.
15066 * Makefile.in (base_obj): Add back doprnt.o.
15068 * deps.mk (doprnt.o): Add back prerequisites.
15069 (callint.o): Depend on character.h.
15071 * eval.c (internal_lisp_condition_case): Include the handler
15072 representation in the error message.
15073 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
15074 when breaking from the loop.

15078 * callint.c (Fcall_interactively): When displaying error message
15079 about invalid control letter, pass the character's codepoint, not
15080 a pointer to its multibyte form. Improve display of the character
15081 in octal and display also its hex code.
15083 * character.c (char_string): Use %x to display the (unsigned)
15084 codepoint of an invalid character, to avoid displaying a bogus
15087 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15088 `error', not SYMBOL_NAME itself.
15090 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
15091 character arguments to `error'.
15093 * charset.c (check_iso_charset_parameter): Fix incorrect argument
15094 to `error' in error message about FINAL_CHAR argument. Make sure
15095 FINAL_CHAR is a character, and use %c when it is passed as
15096 argument to `error'.

15160 Define only if needed.
15162 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
15163 by pacifying GCC about it. Maybe it's time to retire it?
15164 * xfaces.c (USG, __TIMEVAL__): Likewise.
15166 * dispextern.h (struct redisplay_interface): Rename param
15167 to avoid shadowing.
15168 * termhooks.h (struct terminal): Likewise.
15169 * xterm.c (xembed_send_message): Likewise.
15171 * insdel.c (make_gap_smaller): Define only if
15172 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
15174 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
15177 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
15178 so that we aren't warned about unused symbols.
15180 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
15182 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
15184 * xfns.c (x_real_positions): Mark locals as initialized.
15186 * xmenu.c (xmenu_show): Don't use uninitialized vars.
15188 * xterm.c: Fix problems found by static analysis with other toolkits.
15189 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
15190 (x_dispatch_event): Declare static if USE_GTK, and
15191 define if USE_GTK || USE_X_TOOLKIT.
15192 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
15193 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.

15195 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
15197 * xmenu.c (menu_help_callback): Pointer type fixes.
15198 Use const pointers when pointing at readonly data. Avoid pointer
15199 signedness clashes.

15201 (update_frame_menubar): Remove unused decl.
15203 * xfns.c (Fx_hide_tip): Move locals to avoid shadowing.

15285 * nsfont.m: Fixed bugs in ns_get_family and
15286 ns_descriptor_to_entity that were caused by using free to
15287 deallocate memory blocks that were allocated by xmalloc (via
15288 xstrdup). This caused Emacs to crash when compiled with
15289 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
15290 --enable-checking=xmallocoverrun). xfree is now used to
15291 deallocate these memory blocks.

15653 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
15654 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
15655 was inaccessible from Lisp.
15656 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
15657 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
15659 alloc.c: Import and export fewer symbols, and remove unused items.
15660 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
15662 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
15663 it's not optimized away by whole-program optimization.
15664 (message_enable_multibyte, free_misc): Remove.
15665 (catchlist, handlerlist, mark_backtrace):
15666 Declare only if BYTE_MARK_STACK.
15667 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
15668 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
15669 (message_enable_multibyte): Remove decl.
15670 (free_misc, interval_free_list, float_block, float_block_index):
15671 (n_float_blocks, float_free_list, cons_block, cons_block_index):
15672 (cons_free_list, last_marked_index):
15674 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
15675 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
15676 (mark_backtrace): Define only if BYTE_MARK_STACK.
15677 * xdisp.c (message_enable_multibyte): Now static.
15679 Declare Lisp_Object Q* variables to be 'static' if not exported.
15680 This makes it easier for human readers (and static analyzers)
15681 to see whether these variables are used from other modules.
15682 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
15683 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
15684 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
15685 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
15686 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
15687 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
15688 * xmenu.c, xselect.c:
15689 Declare Q* vars static if they are not used in other modules.
15690 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
15691 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
15692 Remove decls of unexported vars.
15693 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
15695 * lisp.h (DEFINE_FUNC): Make sname 'static'.
15697 Make Emacs functions such as Fatom 'static' by default.
15698 This makes it easier for human readers (and static analyzers)
15699 to see whether these functions can be called from other modules.
15700 DEFUN now defines a static function. To make the function external
15701 so that it can be used in other C modules, use the new macro DEFUE.
15702 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
15703 (Finit_image_library):
15704 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
15705 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
15706 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
15707 Remove decls, since these functions are now static.
15708 (Funintern, Fget_internal_run_time): New decls, since these functions
15709 were already external.
15711 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
15712 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
15713 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
15714 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
15715 * keyboard.c, keymap.c, lread.c:
15716 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
15717 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
15718 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
15719 Mark functions with DEFUE instead of DEFUN,
15720 if they are used in other modules.
15721 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
15722 decls for now-static functions.
15723 * buffer.h (Fdelete_overlay): Remove decl.
15724 * callproc.c (Fgetenv_internal): Mark as internal.
15725 * composite.c (Fremove_list_of_text_properties): Remove decl.

15729 * doc.c (Fdocumntation_property): New forward static decl.
15730 * eval.c (Ffetch_bytecode): New forward static decl.
15731 (Funintern): Remove extern decl; now in .h file where it belongs.
15732 * fileio.c (Fmake_symbolic_link): New forward static decl.
15733 * image.c (Finit_image_library): New forward static decl.
15734 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
15735 * intervals.h (Fprevious_property_change):
15736 (Fremove_list_of_text_properties): Remove decls.
15737 * keyboard.c (Fthis_command_keys): Remove decl.
15738 (Fcommand_execute): New forward static decl.
15739 * keymap.c (Flookup_key): New forward static decl.
15740 (Fcopy_keymap): Now static.
15741 * keymap.h (Flookup_key): Remove decl.
15742 * process.c (Fget_process): New forward static decl.
15743 (Fprocess_datagram_address): Mark as internal.
15744 * syntax.c (Fsyntax_table_p): New forward static decl.
15745 (skip_chars): Remove duplicate decl.
15746 * textprop.c (Fprevious_property_change): New forward static decl.
15747 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
15749 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
15750 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.

15754 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
15756 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
15759 2011-04-13 Eli Zaretskii <eliz@gnu.org>
15761 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
15762 when at ZV. (Bug#8487)
15764 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
15766 * charset.c (Fclear_charset_maps): Use xfree instead of free.
15768 * keyboard.c (parse_tool_bar_item): Likewise.
15769 * sound.c (sound_cleanup, alsa_close): Likewise.
15770 * termcap.c (tgetent): Likewise.
15771 * xfns.c (x_default_font_parameter): Likewise.
15772 * xsettings.c (read_and_apply_settings): Likewise.
15774 * alloc.c (overrun_check_malloc, overrun_check_realloc)
15775 (overrun_check_free): Protoize.
15777 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
15779 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
15780 since callers should never pass a negative size.
15781 Change the signature to match that of plain 'read' and 'write'; see
15782 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
15783 * lisp.h: Update prototypes of emacs_write and emacs_read.
15785 2011-04-11 Eli Zaretskii <eliz@gnu.org>
15787 * xdisp.c (redisplay_window): Don't try to determine the character
15788 position of the scroll margin if the window start point w->startp
15789 is outside the buffer's accessible region. (Bug#8468)
15791 2011-04-10 Eli Zaretskii <eliz@gnu.org>
15793 Fix write-region and its subroutines for buffers > 2GB.
15794 * fileio.c (a_write, e_write): Modify declaration of arguments and
15795 local variables to support buffers larger than 2GB.
15796 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
15798 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
15799 argument, local variables, and return value.
15801 * lisp.h: Update prototypes of emacs_write and emacs_read.
15803 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
15805 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
15807 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
15809 Fix more problems found by GCC 4.6.0's static checks.
15811 * xdisp.c (vmessage): Use a better test for character truncation.
15813 * charset.c (load_charset_map): <, not <=, for optimization,
15814 and to avoid potential problems with integer overflow.
15815 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
15816 * casetab.c (set_identity, shuffle): Likewise.
15817 * editfns.c (Fformat): Likewise.
15818 * syntax.c (skip_chars): Likewise.
15820 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
15821 This also lets GCC 4.6.0 generate slightly better loop code.
15823 * callint.c (Fcall_interactively): <, not <=, for optimization.
15824 (Fcall_interactively): Count the number of arguments produced,
15825 not the number of arguments given. This is simpler and lets GCC
15826 4.6.0 generate slightly better code.
15828 * ftfont.c: Distingish more carefully between FcChar8 and char.
15829 The previous code passed unsigned char * to a functions like
15830 strlen and xstrcasecmp that expect char *, which does not
15831 conform to the C standard.
15832 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
15833 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
15834 char * when the C standard requires it.
15836 * keyboard.c (read_char): Remove unused var.
15838 * eval.c: Port to Windows vsnprintf (Bug#8435).
15839 Include <limits.h>.
15840 (SIZE_MAX): Define if the headers do not.
15841 (verror): Do not give up if vsnprintf returns a negative count.
15842 Instead, grow the buffer. This ports to Windows vsnprintf, which
15843 does not conform to C99. Problem reported by Eli Zaretskii.
15844 Also, simplify the allocation scheme, by avoiding the need for
15845 calling realloc, and removing the ALLOCATED variable.
15847 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
15849 Remove invocations of doprnt, as Emacs now uses vsnprintf.
15850 But keep the doprint source code for now, as we might revamp it
15851 and use it again (Bug#8435).
15852 * lisp.h (doprnt): Remove.
15853 * Makefile.in (base_obj): Remove doprnt.o.
15854 * deps.mk (doprnt.o): Remove.
15856 error: Print 32- and 64-bit integers portably (Bug#8435).
15857 Without this change, on typical 64-bit hosts error ("...%d...", N)
15858 was used to print both 32- and 64-bit integers N, which relied on
15859 undefined behavior.
15860 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
15861 * lisp.h (error, verror): Mark as printf-like functions.
15862 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
15863 Report overflow in size calculations when allocating printf buffer.
15864 Do not truncate output string at its first null byte.
15865 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
15866 Truncate the output at a character boundary, since vsnprintf does not
15868 * charset.c (check_iso_charset_parameter): Convert internal
15869 character to string before calling 'error', since %c now has the
15871 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
15872 overflow when computing char to be passed to 'error'. Do not
15873 pass Lisp_Object to 'error'; pass the integer instead.
15874 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
15875 formatted with plain %d.
15877 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
15879 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
15881 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
15883 * xterm.c (x_catch_errors): Remove duplicate declaration.
15885 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
15887 * xdisp.c, lisp.h (message_nolog): Remove; unused.
15889 2011-04-10 Jim Meyering <meyering@redhat.com>
15891 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
15892 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
15893 return ssize_t not "int", and use size_t as the buffer length.
15894 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
15895 * gnutls.h: Update declarations.
15896 * process.c (read_process_output): Use ssize_t, to match.
15897 (send_process): Likewise.
15899 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15901 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
15903 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15905 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
15906 Use unsigned char, to match FcChar8 type definition.
15908 * xterm.c (handle_one_xevent):
15909 * xmenu.c (create_and_show_popup_menu):
15910 * xselect.c (x_decline_selection_request)
15911 (x_reply_selection_request): Avoid type-punned deref of X events.
15913 2011-04-09 Eli Zaretskii <eliz@gnu.org>
15915 Fix some uses of `int' instead of EMACS_INT.
15916 * search.c (string_match_1, fast_string_match)
15917 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
15918 (scan_buffer, find_next_newline_no_quit)
15919 (find_before_next_newline, search_command, Freplace_match)
15920 (Fmatch_data): Make some `int' variables be EMACS_INT.
15922 * xdisp.c (display_count_lines): 3rd argument and return value now
15923 EMACS_INT. All callers changed.
15924 (pint2hrstr): Last argument is now EMACS_INT.
15926 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
15927 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
15928 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
15929 (decode_coding_utf_16, decode_coding_emacs_mule)
15930 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
15931 (decode_coding_ccl, decode_coding_charset)
15932 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
15933 (decode_coding_iso_2022, decode_coding_emacs_mule)
15934 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
15935 <char_offset, last_offset>: Declare EMACS_INT.
15936 (encode_coding_utf_8, encode_coding_utf_16)
15937 (encode_coding_emacs_mule, encode_invocation_designation)
15938 (encode_designation_at_bol, encode_coding_iso_2022)
15939 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
15940 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
15942 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
15943 (encode_invocation_designation): Last argument P_NCHARS is now
15945 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
15946 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
15948 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
15951 * ccl.c (Fccl_execute_on_string): Declare some variables
15954 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
15956 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
15958 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
15960 * process.c (Fformat_network_address): Doc fix.
15962 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
15964 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
15966 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
15968 * keyboard.c (read_char): Call Lisp function help-form-show,
15969 instead of using internal_with_output_to_temp_buffer.
15970 (Qhelp_form_show): New var.
15971 (syms_of_keyboard): Use DEFSYM macro.
15973 * print.c (internal_with_output_to_temp_buffer): Function deleted.
15975 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
15977 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
15979 * process.c (Flist_processes): Remove to Lisp.
15980 (list_processes_1): Delete.
15982 2011-04-06 Eli Zaretskii <eliz@gnu.org>
15984 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
15986 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
15988 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
15990 Fix more problems found by GCC 4.6.0's static checks.
15992 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
15994 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
15996 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
15998 * xdisp.c (vmessage): Mark as a printf-like function.
16000 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
16002 * sound.c (sound_warning): Don't crash if arg contains a printf format.
16004 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
16005 printf-like functions.
16006 (tiff_load): Add casts to remove these marks before passing them
16007 to system-supplied API.
16009 * eval.c (Fsignal): Remove excess argument to 'fatal'.
16011 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
16012 This avoids several warnings with gcc -Wstrict-overflow.
16013 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
16014 directly, rather than having caller test rule sign. This avoids
16015 some unnecessary tests.
16016 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
16017 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
16018 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
16020 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16021 (xfont_open): Avoid unnecessary tests.
16023 * composite.c (composition_gstring_put_cache): Use unsigned integer.
16025 * composite.h, composite.c (composition_gstring_put_cache):
16026 Use EMACS_INT, not int, for length.
16028 * composite.h (COMPOSITION_DECODE_REFS): New macro,
16029 breaking out part of COMPOSITION_DECODE_RULE.
16030 (COMPOSITION_DECODE_RULE): Use it.
16031 * composite.c (get_composition_id): Remove unused local vars,
16032 by using the new macro.
16034 * textprop.c (set_text_properties_1): Change while to do-while,
16035 since the condition is always true at first.
16037 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16038 (interval_deletion_adjustment): Return unsigned value.
16041 * process.c (list_processes_1, create_pty, read_process_output):
16042 (exec_sentinel): Remove vars that were set but not used.
16043 (create_pty): Remove unnecessary "volatile"s.
16044 (Fnetwork_interface_info): Avoid possibility of int overflow.
16045 (read_process_output): Do adaptive read buffering even if carryover.
16046 (read_process_output): Simplify nbytes computation if buffered.
16048 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
16050 * syntax.c (scan_words): Remove var that was set but not used.
16051 (update_syntax_table): Use unsigned instead of int.
16053 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
16054 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
16055 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
16057 * print.c (print_error_message): Avoid int overflow.
16059 * font.c (font_list_entities): Redo for clarity,
16060 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
16062 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
16063 (font_score): Avoid potential overflow in diff calculation.
16065 * fns.c (substring_both): Remove var that is set but not used.
16066 (sxhash): Redo loop for clarity and to avoid wraparound warning.
16068 * eval.c (funcall_lambda): Rename local to avoid shadowing.
16070 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
16071 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
16072 can always succeed if overflow has undefined behavior.
16074 * search.c (boyer_moore, wordify): Remove vars set but not used.
16075 (wordify): Omit three unnecessary tests.
16077 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
16078 All callers changed. This avoids the need for an unused var.

16090 Check for integer overflow on size calculations.
16092 * buffer.c (Fprevious_overlay_change): Remove var that is set
16095 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16096 Remove vars that are set but not used.
16097 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16098 (timer_check_2): Mark vars as initialized.
16100 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16102 * image.c (lookup_image): Remove var that is set but not used.
16103 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16105 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16106 that are set but not used.
16108 * xfns.c (make_invisible_cursor): Don't return garbage
16109 if XCreateBitmapFromData fails (Bug#8410).
16111 * xselect.c (x_get_local_selection, x_handle_property_notify):
16112 Remove vars that are set but not used.
16114 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

16118 Remove var that is set but not used.
16119 (scroll_bar_windows_size): Now size_t, not int.
16120 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16121 Check for overflow.
16123 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16124 (map_tty_color) [!defined MSDOS]: Likewise.
16126 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16128 * coding.c: Remove vars that are set but not used.
16129 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
16130 All callers changed.

16138 * print.c (print_object): Remove var that is set but not used.
16140 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16141 The gnulib version avoids calling malloc in the usual case,
16142 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16143 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16144 * filelock.c (current_lock_owner): Likewise.
16145 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16146 * sysdep.c: Include allocator.h, careadlinkat.h.
16147 (emacs_no_realloc_allocator): New static constant.
16148 (emacs_readlink): New function.
16149 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16150 ../lib/careadlinkat.h.
16152 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
16154 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

16176 do not dereference NULL upon failed strdup
16177 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16178 (ns_get_family): Likewise.
16180 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16182 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16184 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16186 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16189 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16191 Add lexical binding.
16193 * window.c (Ftemp_output_buffer_show): New fun.

16202 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16204 (syms_of_lread): Declare `lexical-binding'.
16206 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16208 * keyboard.c (eval_dyn): New fun.
16209 (menu_item_eval_property): Use it.
16211 * image.c (parse_image_spec): Use Ffunctionp.
16213 * fns.c (concat, mapcar1): Accept byte-code-functions.
16215 * eval.c (Fsetq): Handle lexical vars.
16216 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16217 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16218 (FletX, Flet): Obey lexical binding.
16219 (Fcommandp): Handle closures.
16220 (Feval): New `lexical' arg.
16221 (eval_sub): New function extracted from Feval. Use it almost
16222 everywhere where Feval was used. Look up vars in lexical env.
16224 (Ffunctionp): Move from subr.el.
16225 (Ffuncall): Handle closures.
16226 (apply_lambda): Remove `eval_flags'.
16227 (funcall_lambda): Handle closures and new byte-code-functions.
16228 (Fspecial_variable_p): New function.
16229 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16230 but without exporting it to Lisp.
16232 * doc.c (Fdocumentation, store_function_docstring):
16233 * data.c (Finteractive_form): Handle closures.
16235 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16238 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16240 (exec_byte_code): New function extracted from Fbyte_code to handle new
16241 calling convention for byte-code-functions. Add new byte-codes.
16243 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
16245 * alloc.c (Fmake_symbol): Init new `declared_special' field.

16249 * xdisp.c (redisplay_internal): Fix prototype.
16251 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16253 * xdisp.c (SCROLL_LIMIT): New macro.
16254 (try_scrolling): Use it when setting scroll_limit.
16255 Limit scrolling to 100 screen lines.
16256 (redisplay_window): Even when falling back on "recentering",
16257 position point in the window according to scroll-conservatively,
16258 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16260 (try_scrolling): When point is above the window, allow searching
16261 as far as scroll_max, or one screenful, to compute vertical
16262 distance from PT to the scroll margin position. This prevents
16263 try_scrolling from unnecessarily failing when
16264 scroll-conservatively is set to a value slightly larger than the
16265 window height. Clean up the case of PT below the margin at bottom
16266 of window: scroll_max can no longer be INT_MAX. When aggressive
16267 scrolling is in use, don't let point enter the opposite scroll
16268 margin as result of the scroll.
16269 (syms_of_xdisp) <scroll-conservatively>: Document the
16270 threshold of 100 lines for never-recentering scrolling.
16272 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

16277 (message_log_check_duplicate): Remove parameters `prev_bol' and
16278 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16279 (redisplay_internal): Remove parameter `preserve_echo_area',
16280 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16282 * indent.c (Fvertical_motion):
16283 * window.c (window_scroll_pixel_based, Frecenter):
16284 Don't pass `need_y_p' to `move_it_by_lines'.
16286 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16288 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16289 steal a few bits to be more compact.
16290 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16291 Remove unneeded casts.
16293 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16295 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16297 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16298 binding" message (bug#7967).
16300 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16302 Fix more problems found by GCC 4.6.0's static checks.
16304 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16305 Remove unused local var.
16307 * editfns.c (Fmessage_box): Remove unused local var.
16309 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16310 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16311 Omit unused local vars.
16312 * window.c (shrink_windows): Omit unused local var.
16313 * menu.c (digest_single_submenu): Omit unused local var.
16314 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16315 Omit unused local var.
16317 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16318 Don't assume string length fits in int.
16319 (keyremap_step, read_key_sequence): Use size_t for sizes.

16323 instead of alloca (Bug#8344).
16325 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16326 (Fbacktrace_frame): Don't assume nframes fits in int.
16328 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

16335 * cm.c (calccost): Turn while-do into do-while, for clarity.
16337 * keyboard.c (syms_of_keyboard): Use the same style as later
16338 in this function when indexing through an array. This also
16339 works around GCC bug 48267.
16341 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16343 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16345 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16346 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16348 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16349 This avoids undefined behavior on integer overflow, and is a bit
16350 more convenient anyway since it is compared to a size_t variable.
16352 Variadic C functions now count arguments with size_t, not int.
16353 This avoids an unnecessary limitation on 64-bit machines, which
16354 caused (substring ...) to crash on large vectors (Bug#8344).

16364 * fns.c (concat): Likewise.
16365 * frame.c (x_set_frame_parameters): Likewise.
16366 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16367 0 if not found, not -1. All callers changed.
16369 * alloc.c (garbage_collect): Don't assume stack size fits in int.
16370 (stack_copy_size): Now size_t, not int.
16371 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
16373 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
16375 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
16376 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

16392 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,

16396 Vcommand_hook_internal.

16537 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
16539 * w32term.c (x_set_glyph_string_clipping):
16540 Don't pass uninitialized region to CombineRgn.

16566 * term.c (Fsuspend_tty, Fresume_tty):
16567 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
16568 * window.c (temp_output_buffer_show):

16576 * buffer.c (Fkill_all_local_variables):
16577 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
16579 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
16580 unconditionally since it does the check itself.
16582 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
16584 Fix more problems found by GCC 4.5.2's static checks.
16586 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16587 the first time through the loop, since we know p0 < p1 then.
16588 This also avoids a gcc -Wstrict-overflow warning.
16590 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16591 leading to a memory leak, possible in functions like
16592 load_charset_map_from_file that can allocate an unbounded number
16593 of objects (Bug#8318).
16595 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16596 that could (at least in theory) be that large.
16598 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16599 This is less likely to overflow, and avoids undefined behavior if
16600 overflow does occur. All callers changed. Use strtoul to scan
16601 for the unsigned long integer.
16602 (pint2hrstr): Simplify and tune code slightly.
16603 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
16605 * scroll.c (do_scrolling): Work around GCC bug 48228.
16606 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
16608 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
16609 This also avoids a warning with gcc -Wstrict-overflow.

16611 This also avoids a warning with gcc -Wstrict-overflow.
16613 * fileio.c (Fcopy_file): Report error if fchown or fchmod
16616 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
16618 * process.c (Fmake_network_process): Use socklen_t, not int,
16619 where POSIX says socklen_t is required in portable programs.
16620 This fixes a porting bug on hosts like 64-bit HP-UX, where
16621 socklen_t is wider than int (Bug#8277).
16622 (Fmake_network_process, server_accept_connection):
16623 (wait_reading_process_output, read_process_output):
16626 * process.c: Rename or move locals to avoid shadowing.

16636 Make tparam.h and terminfo.c consistent.
16637 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
16638 Include tparam.h instead, since it declares them.
16639 * cm.h (PC): Remove extern decl; tparam.h now does this.
16640 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
16641 * terminfo.c: Include tparam.h, to check interfaces.
16642 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
16643 (tparam): Adjust signature to match interface in tparam.h;
16644 this removes some undefined behavior. Check that outstring and len
16645 are zero, which they always are with Emacs.
16646 * tparam.h (PC, BC, UP): New extern decls.
16648 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
16649 (xftfont_open): Rename locals to avoid shadowing.
16651 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
16652 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
16653 (OTF_TAG_SYM): Omit macro if not needed.

16661 * xml.c (make_dom): Now static.
16663 * composite.c (composition_compute_stop_pos): Rename local to
16665 (composition_reseat_it): Remove unused locals.
16666 (find_automatic_composition, composition_adjust_point): Likewise.
16667 (composition_update_it): Mark var as initialized.
16668 (find_automatic_composition): Mark vars as initialized,
16669 with a FIXME (Bug#8290).

16672 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
16673 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
16674 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
16675 (BUF_DEC_POS): Be more systematic about renaming local temporaries
16676 to avoid shadowing.
16678 * textprop.c (property_change_between_p): Remove; unused.
16680 * intervals.c (interval_start_pos): Now static.
16682 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

16685 Rename locals to avoid shadowing.
16687 * sound.c (wav_play, au_play, Fplay_sound_internal):
16688 Fix pointer signedness.
16689 (alsa_choose_format): Remove unused local var.
16690 (wav_play): Initialize a variable to 0, to prevent undefined
16691 behavior (Bug#8278).
16693 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
16695 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
16697 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
16698 clobbering (Bug#8298).
16699 * sysdep.c (sys_subshell): Likewise.
16700 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
16702 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
16703 This should get cleaned up, so that child_setup has the
16704 same signature on all platforms.
16706 * callproc.c (call_process_cleanup): Now static.
16707 (relocate_fd): Rename locals to avoid shadowing.
16709 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
16711 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
16712 not to be necessary, and produces flickering.
16714 2011-03-20 Glenn Morris <rgm@gnu.org>
16716 * config.in: Remove file.
16718 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
16720 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
16721 are now in src/globals.h.
16722 (syms_of_minibuf): Remove spurious & from previous change.
16724 2011-03-20 Leo Liu <sdl.web@gmail.com>
16726 * minibuf.c (completing-read-function): New variable.
16727 (completing-read-default): Rename from completing-read.
16728 (completing-read): Call completing-read-function.
16730 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16732 * xfaces.c (Fx_load_color_file):
16733 Read color file from absolute filename (bug#8250).
16735 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16737 * makefile.w32-in: Update dependencies.
16739 2011-03-17 Eli Zaretskii <eliz@gnu.org>
16741 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

16748 (sigchld_handler): Now static.
16750 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
16751 That way, the code declares only the vars that it needs.
16752 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
16753 * s/cygwin.h (PTY_ITERATION): Likewise.
16754 * s/darwin.h (PTY_ITERATION): Likewise.

16761 (CONSTANTLIM): Remove; unused.
16762 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
16763 Define only if needed.
16765 * unexelf.c (unexec): Name an expression,
16766 to avoid gcc -Wbad-function-cast warning.
16767 Use a different way to cause a compilation error if anyone uses
16768 n rather than nn, a way that does not involve shadowing.
16769 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
16771 * deps.mk (unexalpha.o): Remove; unused.
16773 New file unexec.h, the (simple) interface for unexec (Bug#8267).
16774 * unexec.h: New file.
16775 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
16776 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
16777 Depend on unexec.h.
16778 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
16779 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
16780 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
16781 Change as necessary to match prototype in unexec.h.
16783 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

16800 (font_sort_entities): Mark var as initialized.
16802 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
16804 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

16816 * floatfns.c (domain_error2): Define only if needed.
16817 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
16819 * alloc.c (mark_backtrace): Move decl from here ...

16828 * callint.c (quotify_arg, quotify_args): Now static.
16829 (Fcall_interactively): Rename locals to avoid shadowing.
16830 Use const pointer when appropriate.

16836 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
16837 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
16838 some of which prompt warnings from gcc -Wbad-function-cast.
16839 (Fformat_time_string, Fencode_time, Finsert_char):
16840 (Ftranslate_region_internal, Fformat):
16841 Rename or remove local vars to avoid shadowing.
16842 (Ftranslate_region_internal): Mark var as initialized.
16844 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
16847 * lisp.h (eassert): Check that the argument compiles, even if
16848 ENABLE_CHECKING is not defined.
16850 * data.c (Findirect_variable): Name an expression, to avoid
16851 gcc -Wbad-function-cast warning.

16860 Rename locals to avoid shadowing.
16861 (mark_stack): Move local variables into the #ifdef region where
16863 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
16864 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
16866 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
16867 (GC_STRING_CHARS): Remove; not used.
16868 (Fmemory_limit): Cast sbrk's returned value to char *.
16870 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
16871 avoids undefined behavior in theory.
16873 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.

16876 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16877 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
16878 to use the following functions instead of these macros.
16879 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
16880 EMACS_INT, since callers assume the returned value fits in int.
16881 (upcase1): Likewise, for UPCASE_TABLE.
16882 (uppercasep, lowercasep, upcase): New static inline functions.
16883 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

16888 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
16889 (regex_compile, re_search_2, re_match_2_internal):
16890 Remove unused local vars.
16891 (FREE_VAR): Rewrite so as not to use empty "else",
16892 which gcc can warn about.
16893 (regex_compile, re_match_2_internal): Mark locals as initialized.
16894 (RETALLOC_IF): Define only if needed.
16895 (WORDCHAR_P): Likewise. This one is never needed, but is used
16896 only in a comment talking about a compiler bug, so put inside
16897 the #if 0 of that comment.
16898 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
16899 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
16902 * search.c (boyer_moore): Rename locals to avoid shadowing.
16903 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
16904 (PREV_CHAR_BOUNDARY): Likewise.
16906 * search.c (simple_search): Remove unused var.
16908 * dired.c (compile_pattern): Move decl from here ...

16914 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
16916 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
16917 Rename locals to avoid shadowing.
16918 (Fvertical_motion): Mark locals as initialized.
16920 * casefiddle.c (casify_object, casify_region): Now static.
16921 (casify_region): Mark local as initialized.
16923 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
16925 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
16926 New macros, so that the caller can use some names other than
16927 gcpro1, gcpro2, etc.
16928 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
16930 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
16931 argument, for consistency with GCPRO2_VAR, etc: it is now the
16932 prefix of the variable, not the variable itself. All uses
16934 * dired.c (directory_files_internal, file_name_completion):
16935 Rename locals to avoid shadowing.
16937 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
16938 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
16939 dired.c's scmp function, had undefined behavior.
16940 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16941 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
16942 * buffer.h: ... to here, because these macros use current_buffer,
16943 and the new implementation with inline functions needs to have
16944 current_buffer in scope now, rather than later when the macros
16946 (downcase, upcase1): New static inline functions.
16947 (DOWNCASE, UPCASE1): Reimplement using these functions.
16948 This avoids undefined behavior in expressions like
16949 DOWNCASE (x) == DOWNCASE (y), which previously suffered
16950 from race conditions in accessing the global variables
16951 case_temp1 and case_temp2.
16952 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
16953 * lisp.h (case_temp1, case_temp2): Remove their decls.
16954 * character.h (ASCII_CHAR_P): Move from here ...
16955 * lisp.h: ... to here, so that the inline functions mentioned
16956 above can use them.
16958 * dired.c (directory_files_internal_unwind): Now static.
16960 * fileio.c (file_name_as_directory, directory_file_name):
16961 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
16963 (file_name_as_directory): Use const pointers when appropriate.
16964 (Fexpand_file_name): Likewise. In particular, newdir might
16965 point at constant storage, so make it a const pointer.
16966 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
16967 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer

17399 Move these decls to tparam.h, and make them agree with what
17400 is actually in tparam.c. The previous trick of using incompatible
17401 decls in different modules does not conform to the C standard.
