1 2012-09-22 Kenichi Handa <handa@gnu.org>
3 * composite.c (composition_reseat_it): Handle the case that a
4 grapheme cluster is not covered by a single font (Bug#12352).
6 2012-09-21 Chong Yidong <cyd@gnu.org>
8 * image.c (define_image_type): Avoid adding duplicate types to
9 image_types (Bug#12463). Suggested by Jörg Walter.
11 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
14 (print_load_command_name): Add case LC_DATA_IN_CODE.
15 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
17 2012-09-21 Glenn Morris <rgm@gnu.org>
19 * eval.c (Frun_hook_with_args_until_success)
20 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
22 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
24 * fileio.c (Ffile_selinux_context): Only call freecon when
25 lgetfilecon succeeded.
26 (Fset_file_selinux_context): Likewise. (Bug#12444)
28 2012-09-21 Eli Zaretskii <eliz@gnu.org>
30 * xdisp.c (try_window_reusing_current_matrix): Under bidi
31 reordering, locate the cursor by calling set_cursor_from_row; if
32 that fails, clear the desired glyph matrix before returning a
33 failure indication to the caller. Fixes leaving garbled display
34 when fast scrolling with a down-key. (Bug#12403)
35 (compute_stop_pos_backwards): Fix a typo that caused crashes while
36 scrolling through multibyte text.
38 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
40 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
41 calling mark_vectorlike since that's the one that marks the window.
42 (mark_discard_killed_buffers): Mark the final cdr.
43 * window.h (struct window): Move prev/next_buffers to the
45 * window.c (make_window): Initialize prev/next_buffers manually.
47 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
49 Omit unused arg EXPECTED from socket hooks.
50 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
51 * nsterm.m (ns_term_init):
52 * termhooks.h (struct terminal.read_socket_hook):
53 * w32inevt.c (w32_console_read_socket):
54 * w32term.c (w32_read_socket):
55 * xterm.c (XTread_socket):
56 Omit unused arg EXPECTED. All callers changed.
57 (store_user_signal_events): Return void, not int, since callers no
58 longer care about the return value. All uses changed.
60 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
62 * w32gui.h (XParseGeometry): Do not declare.
64 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
66 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
67 Ignore 'expected'. See Eli Zaretskii in
68 <http://bugs.gnu.org/12471#8> (last line).
70 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
71 (XParseGeometry): Now static. Substitute extremal values for
72 values that are out of range.
74 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
76 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
78 * nsfns.m (XParseGeometry): Remove.
79 (Fx_create_frame): Call x_set_offset to correctly interpret
82 * frame.c (read_integer, XParseGeometry): Moved from w32xfns.c.
83 (Fx_parse_geometry): If there is a space in string, call
84 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
86 2012-09-17 Eli Zaretskii <eliz@gnu.org>
88 * search.c (scan_buffer): Use character positions in calls to
89 region_cache_forward and region_cache_backward, not byte
90 positions. (Bug#12196)
92 * w32term.c (w32_read_socket): Set pending_signals to 1, like
93 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
95 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
96 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
97 emacs_blocked_malloc, now deleted.
99 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
101 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
102 The workaround was for improving performance on Solaris 2.4, but
103 is getting in the way now. Emacs will still work if someone is
104 still running Solaris 2.4 in a museum somewhere; Sun dropped
105 support for Solaris 2.4 in 2003.
106 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
107 * process.c (create_process) [HAVE_WORKING_VFORK]:
108 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
109 since Emacs no longer uses vfork on that platform.
111 2012-09-17 Glenn Morris <rgm@gnu.org>
113 * emacs.c: Use COPYRIGHT.
115 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
117 Remove configure's --without-sync-input option (Bug#12450).
118 When auditing signal-handling in preparation for cleaning it up,
119 I found that SYNC_INPUT has race conditions and would be a real
120 pain to fix. Since it's an undocumented and deprecated
121 configure-time option, now seems like a good time to remove it.
122 Also see <http://bugs.gnu.org/11080#16>.
123 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
124 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
125 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
127 (check_depth) [XMALLOC_OVERRUN_CHECK]:
128 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
129 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
130 (dont_register_blocks, bytes_used_when_reconsidered)
131 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
132 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
133 [!SYSTEM_MALLOC && !SYNC_INPUT]:
134 Remove. All uses removed.
135 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
136 implementation, one that depends on whether the new macro
137 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
139 * atimer.c (run_timers, handle_alarm_signal):
140 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
141 (handle_async_input, process_pending_signals)
142 (handle_input_available_signal, init_keyboard):
143 * nsterm.m (ns_read_socket):
144 * process.c (wait_reading_process_output):
145 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
146 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
148 * xterm.c (XTread_socket):
150 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
151 * eval.c (handling_signal): Remove. All uses removed.
152 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
153 All uses replaced with the SYNC_INPUT version.
154 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
156 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
159 * font.c (Ffont_shape_gstring): Remove unused local.
161 2012-09-16 Glenn Morris <rgm@gnu.org>
163 * Makefile.in (clean): No longer run nextstep's clean.
165 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
167 (ns-app): Move here from ns.mk, and simplify.
168 (clean): Simplify nextstep entry.
169 * ns.mk: Remove file.
171 2012-09-17 Kenichi Handa <handa@gnu.org>
173 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
174 not covert the last few charactes.
176 2012-09-16 Kenichi Handa <handa@gnu.org>
178 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
179 here, but just check the validity of glyphs in the glyph-string.
181 2012-09-16 Martin Rudalics <rudalics@gmx.at>
183 * window.c (Fwindow_parameter, Fset_window_parameter): Accept
184 any window as argument (Bug#12452).
186 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
188 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
189 to ns_term_init to avoid memory leak.
191 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
192 explicit retain/release.
193 (ns_term_init): Only allow one display. Initialize outerpool and
196 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
198 Port _setjmp fix to POSIXish hosts as well as Microsoft.
199 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
200 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
201 the Microsoft problem in a different way, by altering ../nt/config.nt.
203 2012-09-15 Eli Zaretskii <eliz@gnu.org>
218 * w16select.c: Remove inclusion of setjmp.h, as it is now included
219 by lisp.h. This completes removal of setjmp.h inclusion
220 erroneously announced in the previous commit. (Bug#12446)
222 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
225 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
226 not defined as a macro. The latter happens on MS-Windows.
229 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
231 Port better to POSIX hosts lacking _setjmp (Bug#12446).
232 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
233 Some instances of '#include <setjmp.h>' removed, if the
234 only reason for the instance was because "lisp.h" was included.
235 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
236 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
237 and _longjmp with the new symbols. Emacs already uses _setjmp if
238 available, so this change affects only POSIXish hosts that have
239 sigsetjmp but not _setjmp, such as some versions of Solaris and
240 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
241 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
242 (png_load_body) [HAVE_PNG]:
243 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
244 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
245 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
246 since PNG requires jmp_buf. This is the only exception to the
247 general rule that we now use sys_setjmp and sys_longjmp.
248 This exception is OK since this code does not change the signal
249 mask or longjmp out of a signal handler.
251 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
253 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
254 Include "syssignal.h", for 'main_thread'.
256 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
258 Avoid out-of-range marker position (Bug#12426).
259 * insdel.c (replace_range, replace_range_2): Adjust
260 markers before overlays, as suggested by comments.
261 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
262 Remove redundant check before calling offset_intervals.
264 2012-09-14 Martin Rudalics <rudalics@gmx.at>
266 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
267 current buffer (Bug#12387).
269 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
271 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
273 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
275 Use a more backwards-compatible timer format (Bug#12430).
276 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
277 vector element, not from the 4th, since PSECS is now at the end.
278 (Fcurrent_idle_time): Doc fix.
280 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
282 Function to mark objects and remove killed buffers at once.
283 * alloc.c (discard_killed_buffers): Rename to ...
284 (mark_discard_killed buffers) ... new name. Add marking
285 of remaining objects. Fix comment. Adjust users.
286 (mark_object): Do not touch frame buffer lists here.
287 * frame.c (delete_frame): Reset frame buffer lists here.
289 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
291 Better workaround for GNOME bug when --enable-gcc-warnings.
292 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
293 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
294 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
296 Simplify SIGIO usage (Bug#12408).
297 The code that dealt with SIGIO was crufty and confusing, e.g., it
298 played tricks like "#undef SIGIO" but these tricks were not used
299 consistently. Simplify mostly by not #undeffing standard symbols,
300 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
301 or not as we please) rather than "defined SIGIO" (standard symbol
302 that we probably shouldn't #undef).
303 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
304 Modules that need it can include it.
305 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
306 * dispextern.h (ignore_sigio): New decl.
307 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
308 unconditionally, since it's now a no-op if !USABLE_SIGIO.
309 * emacs.c (shut_down_emacs):
310 * keyboard.c (kbd_buffer_store_event_hold):
311 Use ignore_sigio rather than invoking 'signal' directly.
312 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
314 (FIONREAD, SIGIO): Do not #undef.
315 (tty_read_avail_input): Use #error rather than a syntax error.
316 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
317 for I_PIPE, used by SETUP_SLAVE_PTY.
318 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
319 * sysdep.c (croak): Remove; no longer needed. This bit of
320 temporary code, with Fred N. Fish's comment that it's temporary,
321 has been in Emacs since at least 1992!
322 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
323 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
324 * syssignal.h (croak): Remove decl.
325 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
326 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
327 now that we're termios-only.
328 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
329 * term.c (dissociate_if_controlling_tty): Use #error rather than
332 Work around GCC and GNOME bugs when --enable-gcc-warnings.
333 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
334 to work around GNOME bug 683906.
335 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
336 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
337 This works around GCC bug 54561.
339 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
341 More fixes for 'volatile' and setjmp/longjmp.
342 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
343 * image.c (struct png_load_context) [HAVE_PNG]: New type.
344 (png_load_body) [HAVE_PNG]:
345 (jpeg_load_body) [HAVE_JPEG]:
346 New function, with most of the old parent function's body.
347 (png_load) [HAVE_PNG]:
348 (jpeg_load) [HAVE_JPEG]:
349 Invoke the new function, to avoid longjmp munging our locals.
350 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
351 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
352 longjmp is passed 2, as the C standard doesn't guarantee this.
353 Instead, store the failure code into mgr->failure_code.
355 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
357 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
358 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
359 (syms_of_keyboard): Remove support for unread-command-char.
361 2012-09-12 Eli Zaretskii <eliz@gnu.org>
363 * w32proc.c (sys_kill): If PID is our process ID and the signal is
364 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
365 violation. (Bug#12426)
367 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
369 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
371 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
373 * eval.c: Add `inhibit-debugger'.
374 (Qinhibit_debugger): New symbol.
375 (call_debugger): Bind it instead of Qdebug_on_error.
376 (maybe_call_debugger): Test Vinhibit_debugger.
377 (syms_of_eval): Define inhibit-debugger.
378 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
379 (syms_of_xdisp): Remove inhibit-debug-on-message.
381 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
383 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
384 If a nonvolatile local variable is written before a _longjmp to
385 the frame containing the variable, and is read after the _longjmp,
386 the value read is indeterminate. Some local variables of type
387 'struct handler' and 'struct catchtag' are used in this way, so
388 mark each of their slots as volatile if the slot can be set before
389 _longjmp and read afterwards.
390 * lisp.h (struct handler): var and chosen_clause are now volatile.
391 (struct catchtag): val, next, and pdlcount are now volatile.
393 * bidi.c (bidi_push_it, bidi_pop_it):
394 * fns.c (copy_hash_table):
395 * image.c (define_image_type):
396 * keyboard.c (kbd_buffer_store_event_hold):
397 * process.c (Fprocess_send_eof):
398 * xfaces.c (x_create_gc) [HAVE_NS]:
399 * xgselect.c (xg_select):
400 Prefer assignment to memcpy when either will do.
402 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
403 Use pointer-to-a-pointer to simplify and avoid a NILP check each
404 time an item is removed. No need to mark this function 'inline';
405 the compiler knows better than we do.
407 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
409 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
410 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
411 to change_frame_size (Bug#12388).
412 (windowDidResize:): Pass YES to updateFrameSize.
414 * nsterm.h: Add delay parameter to updateFrameSize.
416 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
418 Discard killed buffers from deleted window and frame objects.
419 This reduces an amount of references to killed buffers and
420 helps GC to reclaim them faster.
421 * alloc.c (discard_killed_buffers): New function.
422 (mark_object): Use it for deleted windows and frames.
423 (mark_object): If symbol's value is set up for a killed buffer
424 or deleted frame, restore it's global binding.
425 * data.c (swap_in_global_binding): Add GC notice.
426 (swap_in_symval_forwarding): Use convenient set_blv_where.
427 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
428 * window.h: ... to here.
430 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
432 Convenient macro to check whether the buffer is live.
433 * buffer.h (BUFFER_LIVE_P): New macro.
434 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
435 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
437 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
439 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
440 composition cases (Bug#12364).
442 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
443 overhang of succeeding glyphs overlapping box cursor.
445 * w32term.c (x_draw_glyph_string): Likewise.
447 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
449 Simplify, document, and port floating-point (Bug#12381).
450 The porting part of this patch fixes bugs on non-IEEE platforms
451 with frexp, ldexp, logb.
452 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
454 * floatfns.c: Simplify discussion of functions that Emacs doesn't
455 support, by removing commented-out code and briefly listing the
456 C89 functions excluded. The commented-out stuff was confusing
457 maintenance, e.g., we thought we needed cbrt but it was commented out.
458 (logb): Remove decl; no longer needed.
459 (isfinite): New macro, if not already supplied.
460 (isnan): Don't replace any existing macro.
461 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
462 are present on all C89 platforms.
463 (Ffrexp): Do not special-case zero, as frexp does the right thing
465 (Flogb): Do not use logb, as it doesn't have the desired meaning
466 on hosts that use non-base-2 floating point. Instead, stick with
467 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
468 frexp, to avoid getting an unspecified result.
470 * xdisp.c (Qinhibit_debug_on_message): Now static.
472 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
474 * nsterm.m (ns_update_begin): Set clip path to whole view by using
475 NSBezierPath (Bug#12131).
477 2012-09-10 Chong Yidong <cyd@gnu.org>
479 * fns.c (Fdelq, Fdelete): Doc fix.
481 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
483 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
484 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
486 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
488 * lisp.h (make_lisp_ptr): New macro to replace XSET.
489 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
492 2012-09-09 Eli Zaretskii <eliz@gnu.org>
494 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
495 left fringe if the window has a left margin. This avoids leaving
496 traces of the cursor because its leftmost pixel is not drawn over.
498 * dispnew.c (update_window_line): When the left margin area of a
499 screen line is updated, set the redraw_fringe_bitmaps_p flag of
500 that screen line. (Bug#12277)
502 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
504 Assume C89 or later for math functions (Bug#12381).
505 This simplifies the code, and makes it a bit smaller and faster,
506 and (most important) makes it easier to clean up signal handling
507 since we can stop worring about floating-point exceptions in
508 library code. That was a problem before C89, but the problem
509 went away many years ago on all practical Emacs targets.
510 * data.c, image.c, lread.c, print.c:
511 Don't include <math.h>; no longer needed.
512 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
513 might be autoconfigured, as that never happens.
515 * doprnt.c (DBL_MAX_10_EXP):
517 Remove. C89 or later always defines these.
518 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
519 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
520 (arith_error, domain_error, domain_error2):
521 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
522 no longer needed -- we simply return what C returns. All uses removed.
523 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
525 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
526 Remove. All uses expanded, as these macros are no longer used
527 more than once and are now more trouble than they're worth.
528 (Ftan): Use tan, not sin / cos.
529 (Flogb): Assume C89 frexp.
530 (fmod_float): Assume C89 fmod.
531 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
532 (init_floatfns): Remove. All uses removed.
534 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
536 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
537 compositeToPoint for OSX < 10.6 (Bug#12390).
539 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
541 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
542 This produces more-accurate results.
544 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
546 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
549 2012-09-08 Chong Yidong <cyd@gnu.org>
551 * syntax.c (Fstring_to_syntax): Doc fix.
553 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
555 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
556 in the internal border.
557 (x_set_window_size): Remove static variables and their usage.
558 (ns_redraw_scroll_bars): Fix NSTRACE arg.
559 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
560 fringe/internal border adjustment (Bug#11052).
561 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
562 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
563 (ns_fix_rect_ibw): Remove.
564 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
565 (ns_dumpglyphs_box_or_relief): Ditto.
566 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
568 (ns_dumpglyphs_image): Ditto.
569 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
571 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
572 their usage. Add fringe_extended_p and its use as in other terms.
573 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
574 scroll bar was removed.
575 (updateFrameSize): New function.
576 (windowDidResize): Move code to updateFrameSize and call it.
578 * nsterm.h (EmacsView): Add updateFrameSize.
580 2012-09-07 Chong Yidong <cyd@gnu.org>
582 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
584 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
586 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
588 More signal-handler cleanup (Bug#12327).
589 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
590 Problem introduced when merging patches. Noted by Eli Zaretskii in
591 <http://bugs.gnu.org/12327#67>.
592 * floatfns.c: Comment fix.
593 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
594 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
595 and anyway the declaration is harmless even if SIGDANGER is not defined.
596 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
597 defined BROKEN_FIONREAD). systty.h formerly did this, but other
598 source files not surprisingly expected syssignal.h to define, or
599 not define, SIGIO, and it's cleaner to do it that way, for consistency.
600 Include <sys/ioctl.h>, for FIONREAD.
601 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
602 This eliminates a problem whereby other files mysteriously had
603 to include "syssignal.h" before including "systty.h" if they
604 wanted to use "#ifdef SIGIO".
606 2012-09-07 Eli Zaretskii <eliz@gnu.org>
608 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
610 * w32.c (sigemptyset): Empty the set.
611 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
613 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
615 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
617 * alloc.c (mark_buffer): Revert unsafe marking optimization.
618 (mark_object): Likewise for frame objects.
620 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
622 * syssignal.h (handle_on_main_thread): Always declare,
623 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
624 This ports to platforms without HAVE_PTHREAD.
626 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
628 Signal-handler cleanup (Bug#12327).
629 Emacs's signal handlers were written in the old 4.2BSD style with
630 sigblock and sigmask and so forth, and this led to some
631 inefficiencies and confusion. Rewrite these to use
632 pthread_sigmask etc. without copying signal sets around. Also,
633 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
634 'signal', and instead use functions that do not attempt to take
635 over the system name space. This patch causes Emacs's text
636 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
637 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
638 Do not include <signal.h> or "syssignal.h", as these
639 modules do not use signals.
640 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
641 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
642 Do not include <signal.h>, as "syssignal.h" does that for us now.
643 * atimer.c (sigmask_atimers): New function.
644 (block_atimers, unblock_atimers): New functions,
645 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
647 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
648 no longer needed here.
649 * emacs.c (main): Inspect existing signal handler with sigaction,
650 so that there's no need to block and unblock SIGHUP.
651 * sysdep.c (struct save_signal): New member 'action', replacing
652 old member 'handler'.
653 (save_signal_handlers, restore_signal_handlers):
654 Use sigaction instead of 'signal' to save and restore.
655 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
656 New function. All users of 'signal' modified to use set_sighandler
657 if they're writeonly, and to use sys_signal if they're read+write.
658 (emacs_sigaction_init, forwarded_signal): New functions.
659 (sys_signal): Remove. All uses replaced by calls to sigaction
660 and emacs_sigaction_init, or by direct calls to 'signal'.
661 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
662 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
663 all uses replaced by pthread_sigmask etc. calls.
664 * syssignal.h: Include <signal.h>.
665 (emacs_sigaction_init, forwarded_signal): New decls.
666 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
667 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
668 (sigmask, sys_sigmask): Remove; no longer needed.
669 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
670 (sigblock, sigunblock, sigfree):
671 (sigsetmask) [!defined sigsetmask]:
672 Remove. All uses replaced by pthread_sigmask.
673 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
674 no longer need to be replaced, and its typical old uses
675 are now done via emacs_sigaction_init and sigaction.
676 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
677 (sys_sigdel): Remove; unused.
678 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
680 2012-09-06 Eli Zaretskii <eliz@gnu.org>
682 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
683 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
685 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
687 Explicitly mark buffer_defaults and buffer_local_symbols.
688 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
689 mark_local_symbols here.
690 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
691 since special buffers aren't marked here any more.
692 (allocate_buffer): Chain new buffer with all_buffers here...
693 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
695 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
696 (syms_of_buffer): Remove staticpro of the above.
697 (init_buffer_once): Set names for buffer_defaults and
698 buffer_local_symbols.
700 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
702 Use bool for booleans in font-related modules.
703 * font.c (font_intern_prop, font_style_to_value)
704 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
705 (generate_otf_features, font_check_otf_features, font_check_otf)
706 (font_match_p, font_list_entities, font_at):
707 * fontset.c (fontset_id_valid_p, reorder_font_vector
708 (fontset_find_font, Fset_fontset_font)
709 (face_suitable_for_char_p) [0]:
710 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
711 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
712 (m17n_flt_initialized, ftfont_shape_by_flt):
713 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
714 * nsfont.m (nsfont_draw):
715 * w32font.c (w32font_draw):
716 * w32term.c (x_draw_glyphless_glyph_string_foreground):
717 Use bool for booleans.
718 * font.h: Adjust to above API changes.
719 (struct font, struct font_driver, struct font_driver_list):
720 Use bool for booleans.
721 (struct font): Remove useless member encoding_type.
723 * fontset.c, xftfont.c: Omit unnecessary static decls.
725 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
727 * alloc.c (mark_object): Revert window marking code
728 since it's unsafe for the Fset_window_configuration.
730 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
732 Fix race conditions with signal handlers and errno (Bug#12327).
733 Be more systematic about preserving errno whenever a signal
734 handler returns, even if it's not in the main thread. Do this by
735 renaming signal handlers to distinguish between signal delivery
736 and signal handling. All uses changed.
737 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
738 * data.c (deliver_arith_signal): Rename from arith_error.
739 * dispnew.c (deliver_window_change_signal): Rename from
740 window_change_signal.
741 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
742 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
743 * keyboard.c (deliver_input_available_signal): Rename from
744 input_available_signal.
745 (deliver_user_signal): Rename from handle_user_signal.
746 (deliver_interrupt_signal): Rename from interrupt_signal.
747 * process.c (deliver_pipe_signal): Rename from send_process_trap.
748 (deliver_child_signal): Rename from sigchld_handler.
749 * atimer.c (handle_alarm_signal):
750 * data.c (handle_arith_signal):
751 * dispnew.c (handle_window_change_signal):
752 * emacs.c (handle_fatal_signal, handle_danger_signal):
753 * keyboard.c (handle_input_available_signal):
754 * keyboard.c (handle_user_signal, handle_interrupt_signal):
755 * process.c (handle_pipe_signal, handle_child_signal):
756 New functions, with the actual signal-handling code taken from the
757 original respective signal handlers, sans the sporadic attempts to
758 preserve errno, since that's now done by handle_on_main_thread.
759 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
760 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
761 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
763 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
764 Move initialization of main_thread to sysdep.c's init_signals.
765 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
766 our usage, and simplifies the mainline code.
767 (record_child_status_change): New static function, as a helper
768 for handle_child_signal, and with most of the old child handler's
770 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
771 (handle_child_signal): Use the above.
772 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
773 Moved here from emacs.c.
774 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
775 code moved here from emacs.c's main function.
776 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
777 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
778 lets callers save and restore errno properly.
780 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
782 Remove redundant or unused things here and there.
783 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
784 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
785 * editfns.c (Fcompare_buffer_substrings): Likewise.
786 * frame.h (struct terminal, struct font_driver_list):
787 Remove redundant declarations.
788 * window.h (Qleft, Qright): Likewise.
790 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
792 Do not mark objects from deleted buffers, windows and frames.
793 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
794 (mark_object): Likewise for windows and frames.
796 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
798 * alloc.c (valid_lisp_object_p): Treat killed buffers,
799 buffer_defaults and buffer_local_symbols as valid objects.
800 Return special value to denote them.
802 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
804 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
805 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
806 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
807 (file_name_absolute_p, Fsubstitute_in_file_name):
808 (check_executable, check_writable, Ffile_accessible_directory_p)
809 (Fset_file_selinux_context, Fdefault_file_modes)
810 (Finsert_file_contents, choose_write_coding_system)
811 (Fwrite_region, build_annotations, a_write, e_write)
813 * filelock.c (boot_time_initialized, get_boot_time)
814 (get_boot_time_1, lock_file_1, within_one_second):
815 * floatfns.c (in_float):
816 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
817 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
818 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
819 * lisp.h (struct Lisp_Hash_Table.cmpfn):
820 * window.c (compare_window_configurations):
821 Use bool for booleans.
822 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
823 (Fdefault_file_modes): Now mode_t, not int, for modes.
824 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
825 (internal_delete_file): Now returns void, not a (boolean) int,
826 since nobody was looking at the return value.
827 * lisp.h, window.h: Adjust to above API changes.
829 * xdisp.c (set_message): Simplify and reindent last change.
831 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
833 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
835 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
837 * eval.c (call_debugger): Make the function non-static so that we
838 can call it from set_message.
840 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
841 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
843 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
845 Give more-useful info on a fatal error (Bug#12328).
846 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
847 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
848 of doing the work ourselves.
849 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
851 (fatal_error_backtrace): New function, taken from the guts
852 of the old fatal_error_signal, but with a new option to output
854 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
855 info about the signal than just its number.
856 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
857 * sysdep.c: Include <execinfo.h>
858 (emacs_backtrace): New function, taken partly from the previous
859 code of the 'die' function.
860 (emacs_abort): Call fatal_error_backtrace rather than abort.
862 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
864 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
865 eager (load-time) macro-expansion.
866 * lisp.mk (lisp): Add macroexp.
868 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
870 Simplify redefinition of 'abort' (Bug#12316).
871 Do not try to redefine the 'abort' function. Instead, redo
872 the code so that it calls 'emacs_abort' rather than 'abort'.
873 This removes the need for the NO_ABORT configure-time macro
874 and makes it easier to change the abort code to do a backtrace.
875 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
876 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
877 Remove; sysdep.c's emacs_abort now takes its place.
878 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
879 'abort' changed to use 'emacs_abort'.
880 * msdos.c (dos_abort) [defined abort]: Remove; not used.
881 (abort) [!defined abort]: Rename to ...
882 (emacs_abort): ... new name.
883 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
884 the place of the old 'abort' in emacs.c.
885 * w32.c, w32fns.c (abort): Do not #undef.
886 * w32.c (emacs_abort): Rename from w32_abort.
888 2012-09-04 Eli Zaretskii <eliz@gnu.org>
890 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
891 offsets[j].dv, since the y axis of the screen coordinates points
892 down, while the y axis of the font definition coordinates points
893 up. This fixes display of Arabic diacritics such as KASRA and
894 KASRATAN. (Bug#11860)
896 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
898 Be more systematic about _setjmp vs setjmp.
899 * alloc.c (test_setjmp, mark_stack):
900 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
901 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
902 (png_load, my_error_exit, jpeg_load):
903 * process.c (send_process_trap, send_process):
904 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
905 The underscored versions are up to 30x faster on some hosts.
906 Formerly, the code used setjmp+longjmp sometimes and
907 _setjmp+_longjmp at other times, with no particular reason to
908 prefer setjmp+longjmp.
910 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
912 Fix minor problem found by static checking.
913 * buffer.c (Fdelete_all_overlays): Return nil.
915 2012-09-03 Martin Rudalics <rudalics@gmx.at>
917 * buffer.c (Fdelete_all_overlays): New function.
919 2012-09-03 Chong Yidong <cyd@gnu.org>
921 * gtkutil.c: Add extern decl for Qxft.
923 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
925 * emacs.c, eval.c: Use bool for boolean.
926 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
927 (malloc_using_checking) [DOUG_LEA_MALLOC]:
928 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
929 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)

945 * msdos.c (fatal_error_in_progress): ... from here.

1042 offset adjustment values separately for each cluster. (Bug#11860)
1044 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1045 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1046 about implicit conversions from integer to pointer.
1048 2012-09-01 Daniel Colascione <dancol@dancol.org>
1050 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

1104 window system declarations.
1106 * frame.h: Move common functions here: set_frame_menubar,
1107 x_set_window_size, x_sync, x_get_focus_frame,
1108 x_set_mouse_position, x_set_mouse_pixel_position,
1109 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

1170 * lread.c (init_lread): For out-of-tree builds, only add the
1171 source directory's site-lisp dir to the load-path if it exists,
1172 consistent with in-tree builds. (Bug#12302)
1174 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

1195 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
1196 Add window_closed and button_values. Add void as return value for
1197 add(Button|String|Split). addButton takes int instead of Lisp_Object.
1198 Add process_dialog as new member.

1382 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
1383 * window.h (decode_valid_window):
1386 * character.c, charset.c, chartab.c: Use bool for booleans.
1387 * character.c (lisp_string_width, string_count_byte8)
1388 (string_escape_byte8):
1389 * charset.c (charset_map_loaded, load_charset_map, read_hex):
1390 (load_charset_map_from_file, map_charset_chars)
1391 (Fdefine_charset_internal, define_charset_internal)
1392 (Fdeclare_equiv_charset, find_charsets_in_text)
1393 (Ffind_charset_region, char_charset, Fiso_charset):
1394 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
1395 (sub_char_table_set, sub_char_table_set_range)
1396 (char_table_set_range, optimize_sub_char_table)
1397 (map_sub_char_table):
1398 Use bool for boolean.
1399 * character.c (str_to_unibyte): Omit last boolean argument; it was
1400 always 0. All callers changed.
1401 * character.h, charset.h: Adjust to match previous changes.
1402 * character.h (char_printable_p): Remove decl of nonexistent function.
1403 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
1404 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
1405 are all boolean, so make them single-bit bitfields.
1407 * lisp.h (ASET): Remove attempt to detect side effects.
1408 It was meant to be temporary and it often doesn't work,
1409 because when IDX has side effects the behavior of IDX==IDX
1410 is undefined. See Stefan Monnier in
1411 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
1413 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
1415 * lisp.h (functionp): New function (extracted from Ffunctionp).
1416 (FUNCTIONP): Use it.
1417 * eval.c (Ffunctionp): Use it.
1419 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1421 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
1422 as that's faster and simpler than static storage. Don't bother
1423 with the g_main_context_query overhead if g_main_context_pending
1424 says no events are pending.
1425 (gfds, gfds_size): Remove these static vars.
1426 (xgselect_initialize): Remove; no longer needed.
1427 All uses and decls removed.
1429 * emacs.c (fatal_error_signal_hook): Remove.
1430 All uses removed. This leftover from old code was always 0.
1432 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
1433 * casefiddle.c (casify_object, casify_region):
1434 * casetab.c (set_case_table):
1435 * category.c, category.h (word_boundary_p):
1436 * category.h (CHAR_HAS_CATEGORY):
1437 Use bool for booleans, instead of int.
1439 2012-08-25 Eli Zaretskii <eliz@gnu.org>
1441 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
1443 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1445 On assertion failure, print backtrace if available.
1446 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1447 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1448 * Makefile.in (LIB_EXECINFO): New macro.
1451 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1452 * bytecode.c (exec_byte_code):
1453 * callint.c (check_mark, Fcall_interactively):
1454 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1455 (getenv_internal, sync_process_alive, call_process_exited):
1456 * lisp.h (USE_SAFE_ALLOCA):
1457 Use bool for booleans, instead of int.
1458 * lisp.h, process.h: Adjust prototypes to match above changes.
1459 * callint.c (Fcall_interactively): Don't assume the mark's
1460 offset fits in 'int'.
1462 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1464 * buffer.c, buffer.h: Use bool for boolean.
1465 * buffer.c (reset_buffer_local_variables)
1466 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1467 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
1468 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
1469 (overlay_touches_p, overlay_strings, Foverlay_put)
1470 (report_overlay_modification, call_overlay_mod_hooks):
1471 (mmap_enlarge, mmap_set_vars):
1472 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1473 Use bool for booleans, instead of int.
1474 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1475 since the 1-or-0 return value is always ignored anyway.
1476 (mmap_initialized_p):
1477 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1478 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1480 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1482 * bidi.c: Use bool for boolean.
1483 This is a bit more readable, and makes the text segment of bidi.o
1484 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1485 Presumably it's faster too.
1486 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1488 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1489 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1490 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1491 (bidi_explicit_dir_char, bidi_level_of_next_char)
1492 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1493 Use bool for booleans, instead of int.
1494 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1495 (bidi_unshelve_cache): Adjust decls to match code.
1497 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1499 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1502 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1504 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1505 * atimer.h: Include <stdbool.h>.
1507 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1509 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1510 compile time tests instead of run time tests on systems that do
1512 (FRAME_MAC_P): Remove leftover from deleted code.
1513 * frame.c (syms_of_frame): Remove leftover from deleted code.
1515 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
1517 * nsterm.m (insertText:): Don't clear modifiers if code is space.
1519 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1521 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1522 Otherwise, the compiler complains about (A?B:C) where B is void
1523 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1524 (fontset_add): Return void, for FONTSET_ADD.
1526 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1528 * alloc.c: Use bool for booleans.
1529 (gc_in_progress, abort_on_gc)
1530 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1531 (dont_register_blocks) [GC_MALLOC_CHECK]:
1532 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1533 (check_string_bytes, make_specified_string, memory_full)
1534 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1535 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1536 (mark_stack, valid_pointer_p, make_pure_string)
1537 (Fgarbage_collect, survives_gc_p, gc_sweep):
1538 Use bool for booleans, instead of int.
1539 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1540 Remove unused local.
1541 * alloc.c (PURE_POINTER_P):
1542 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1543 * editfns.c (Fformat):
1544 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1546 * fns.c (sweep_weak_table):
1547 * lisp.h (suppress_checking, push_message, survives_gc_p)
1548 (make_pure_string, gc_in_progress, abort_on_gc):
1549 * lread.c (readchar, read1):
1550 * print.c (Fprin1_to_string):
1551 * xdisp.c (push_message):
1552 Use bool for booleans affected directly or indirectly by
1555 Make recently-introduced setters macros.
1556 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1557 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1558 (set_fontset_default, set_fontset_fallback): Rename from their
1559 upper-case counterparts, and make them functions rather than macros.
1560 This is more consistent with the other recently-introduced setters.
1561 These don't need to be inline, since they're local.
1563 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1565 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1566 the loop (Bug#12247).
1568 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1570 * lisp.h (vcopy): Use memcpy rather than our own loop.
1571 This fixes a performance regression introduced by the recent
1572 addition of vcopy. This means 'vcopy' will need to be modified
1573 for a copying collector, but that's OK. Also, tighten the
1574 checking in the assertion.
1576 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1578 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1579 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1580 non-base glyph for the width of the base character, according to
1581 what x_draw_composite_glyph_string_foreground expects.
1582 Generate WADJUST value according to composition_gstring_width's
1583 expectations, to produce correct width of the composed character.
1584 Reverse the sign of the DU offset produced by ScriptPlace.
1586 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1588 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1590 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1592 Avoid direct writes to contents member of struct Lisp_Vector.
1593 * lisp.h (vcopy): New function to copy data into vector.
1594 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
1595 * fns.c (Ffillarray): Use ASET.
1596 * keyboard.c (timer_check_2): Use AREF and ASET.
1597 (append_tool_bar_item, Frecent_keys): Use vcopy.
1598 * lread.c (read_vector): Use ASET.
1599 * msdos.c (Frecent_doskeys): Use vcopy.
1600 * xface.c (Finternal_copy_lisp_face): Use vcopy.
1601 (Finternal_merge_in_global_face): Use ASET and vcopy.
1602 * xfont.c (xfont_list_pattern): Likewise.
1604 2012-08-21 Martin Rudalics <rudalics@gmx.at>
1606 * window.c (Fwindow_point): For the selected window always return
1607 the position of its buffer's point.
1608 (Fset_window_point): For the selected window always go in its
1609 buffer to the specified position.
1611 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1613 Setter macros for fontsets.
1614 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1615 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1616 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1619 2012-08-20 Glenn Morris <rgm@gnu.org>
1621 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1622 Don't assume that `ln -f' works.
1624 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1626 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1627 and later about non-assignments with no effect. See discussion at
1628 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1631 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1633 Inline setter functions for Lisp_Objects slots of struct specbinding.
1634 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
1637 2012-08-20 Martin Rudalics <rudalics@gmx.at>
1639 * window.c (select_window): Always make selected window's buffer
1642 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1644 Use AREF and ASET for docstrings of category tables.
1645 * category.h (CATEGORY_DOCSTRING): Use AREF.
1646 (SET_CATEGORY_DOCSTRING): Use ASET.
1647 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
1649 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1651 Inline setter functions for hash table members.
1652 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
1653 (set_hash_hash, set_hash_index): Rename with _slot suffix.
1654 (set_hash_key_and_value, set_hash_index, set_hash_next)
1655 (set_hash_hash): New functions.
1656 * charset.c, fns.c: Adjust users.
1658 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1660 Inline getter and setter functions for per-buffer values.
1661 * buffer.h (per_buffer_default, set_per_buffer_default)
1662 (per_buffer_value, set_per_buffer_value): New functions.
1663 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
1664 * buffer.c, data.c: Adjust users.
1666 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
1668 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
1670 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
1672 Rely on <config.h> + <unistd.h> to declare 'environ',
1673 as gnulib does this if the system doesn't.
1674 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
1675 Remove declaration. MS-Windows declares it on stdlib.h which is
1676 included by conf_post.h.
1677 * emacs.c (environ) [DOUG_LEA_MALLOC]:
1678 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
1679 * vm-limit.c: Include <unistd.h>, for 'environ'.
1681 * unexaix.c, unexcoff.c: Include "mem-limits.h".
1682 (start_of_data): Remove decl; mem-limits.h provides it.
1684 * xdisp.c (handle_invisible_prop): Make it a bit faster
1685 and avoid a gcc -Wmaybe-uninitialized diagnostic.
1687 2012-08-19 Chong Yidong <cyd@gnu.org>
1689 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
1692 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
1694 * .gdbinit: Use call instead of set when calling a function in the
1697 * data.c (set_internal): Don't use set_blv_found.
1698 (Fkill_local_variable): Likewise.
1700 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
1702 * nsfont.m (ns_ascii_average_width): Ensure the string
1703 ascii_printable is initialized with a null-terminated character
1704 array. Otherwise, it can contain undesired extra characters.
1706 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1708 port new setting code to Sun C 5.8 2005/10/13
1709 * chartab.c, lisp.h (char_table_set, char_table_set_range):
1710 Return void, not Lisp_Object. Otherwise, the compiler
1711 complains about (A?B:C) where B is void and C is Lisp_Object
1712 when compiling CHAR_TABLE_SET, due to the recent change to
1713 the API of sub_char_table_set_contents.
1715 2012-08-18 Chong Yidong <cyd@gnu.org>
1717 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
1718 for the string case (Bug#3874).
1720 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1722 * buffer.h (BSET): Remove (Bug#12215).
1723 Replace all uses with calls to new setter functions.

1792 New setter functions.
1794 * termhooks.h (TSET): Remove (Bug#12215).
1795 Replace all uses with calls to new setter functions.
1796 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
1797 (TERMHOOKS_INLINE): New macro.
1798 (tset_charset_list, tset_selection_alist): New setter functions.
1799 * terminal.c (TERMHOOKS_INLINE):
1800 Define to EXTERN_INLINE, so that the corresponding functions
1801 are compiled into code.
1802 (tset_param_alist): New setter function.
1804 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
1806 * keyboard.h (KSET): Remove (Bug#12215).

2550 value of EMACSLOADPATH, as it is no longer needed.
2551 (check_windows_init_file): Now external, not static.

2602 * alloc.c (record_xmalloc): New function.
2603 * lisp.h (record_xmalloc): New decl.
2604 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
2605 more like a function. This is because the pointer cast is not
2606 needed. All uses changed.
2607 * print.c (print_string, print_error_message): Avoid length recalc.
2609 Improve fix for macroexp crash with debugging (Bug#12118).
2610 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to

2644 with addition of handling of symlinks and support for 'lstat'.
2645 If possible, get file's attributes and security information by
2646 handle, not by name. Produce S_IFLNK bit for symlinks, when
2647 called from 'lstat'.
2648 (stat, lstat): New functions, call 'stat_worker'.
2649 (symlink, readlink, careadlinkat): Rewritten to create and resolve
2650 symlinks when the underlying filesystem supports them.

2654 Fix macroexp crash on Windows with debugging (Bug#12118).
2655 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
2656 checking subscripts; problem introduced with the recent
2657 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
2658 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
2659 since it's used in non-static inline functions now.
2661 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

3153 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
3154 arms of an 'if', not using conditional expressions; otherwise GDB
3155 complains about the types in the unevaluated arm when the argument
3156 is an integer literal.
3157 (xgetint): Simplify expression.
3158 * alloc.c (gdb_make_enums_visible): New constant. This ports to
3159 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
3160 Zaretskii in <http://bugs.gnu.org/12036#13>.
3161 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
3162 needed now that we have gdb_make_enums_visible.
3163 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
3164 (enum enum_USE_LSB_TAG):
3165 New enum types, packaging up enums that need to be exported to GDB.
3167 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

3183 * xdisp.c (syms_of_xdisp): Likewise.
3184 * xfns.c (syms_of_xfns): Likewise.
3186 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3188 Fast save_excursion_save and save_excursion_restore.
3189 * lisp.h (struct Lisp_Excursion): New data type.
3190 (PVEC_EXCURSION): New pseudovector type.
3191 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
3192 to deal with it. Adjust comments.
3193 (init_marker, attach_marker): New prototype.
3194 (unchain_marker): Adjust prototype.

3206 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
3207 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
3208 emacs.c, as this is a more-suitable home. Had this been done earlier
3209 the fix for 12036 would have avoided some of the problems noted in
3210 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
3211 would have been more obvious.
3212 * emacs.c: Do not include <verify.h>; no longer needed.
3213 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
3214 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
3215 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3216 Remove; now done in lisp.h.
3217 * lisp.h (PUBLISH_TO_GDB): New macro.

3219 (DATA_SEG_BITS): Use it.
3220 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
3221 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3222 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3223 not be usable in #if. This simplifies things.
3225 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
3227 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
3229 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

3232 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3233 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3234 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3235 Adjust to changes in lisp.h and emacs.c, by using
3236 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
3237 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
3238 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
3239 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
3240 instead of gdb_valbits.
3241 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
3242 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
3243 instead of gdb_array_mark_flag.
3244 (xboolvector): Get size from $->size, not $->header.size.
3245 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
3246 (xreload, hook-run, hookpost-run): Remove.
3247 * emacs.c: Include <verify.h>.
3248 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
3249 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
3251 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
3252 (gdb_USE_LSB_TAG): New enum constants.
3253 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3254 Also define these as enum constants, so they're visible to GDB.
3255 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
3256 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
3257 as constants, so they're visible to GDB.
3258 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
3259 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
3260 Now enum constants, not macros, so they're visible to GDB.
3261 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
3262 more convenient now. All uses changed.
3263 (VALMASK) [USE_LSB_TAG]: Also define in this case.
3264 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
3266 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

3273 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
3274 add argument, tune behavior, and adjust all callers.
3276 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
3278 Use typedef for EMACS_INT, EMACS_UINT.
3279 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
3280 than macros. This simplifies debugging in the usual case, since
3281 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
3282 and it allows expressions involving EMACS_INT casts.
3283 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
3285 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

3295 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
3297 Adjust buffer text indirection counters at the end of Fkill_buffer.
3298 * buffer.c (Fkill_buffer): Adjust indirection counters when the
3299 buffer is definitely dead. This should really fix an issue reported
3300 by Christoph Scholtes again. (Bug#12007).
3301 (init_buffer_once): Initialize indirection counters of
3302 buffer_defaults and buffer_local_symbols (for sanity and safety).
3304 2012-07-24 Eli Zaretskii <eliz@gnu.org>
3306 * xdisp.c (init_iterator): Don't compute dimensions of truncation
3307 and continuation glyphs on tooltip frames, leave them at zero.

3335 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3337 Swap buffer text indirection counters in Fbuffer_swap_text.
3338 * buffer.c (Fbuffer_swap_text): Swap indirections too.
3339 This avoids crash reported by Christoph Scholtes at
3340 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
3342 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
3344 * nsmenu.m (Popdown_data): New struct.

3349 and autorelease them. Also autorelease img and matrix (Bug#12005).
3350 (dealloc): Remove (Bug#12005).

3367 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
3369 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
3370 as it's limited by the amount of memory, not by INT_MAX.
3372 2012-07-21 Eli Zaretskii <eliz@gnu.org>
3374 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
3375 in special-event-map. See the discussion at

3435 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
3436 Adjust users accordingly.
3437 * font.h (font_open_by_name): Adjust prototype.

3456 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
3457 'for_each_per_buffer_object_at'.
3458 All uses changed. It's better to use upper-case for macros that
3459 cannot be implemented as functions, to give the reader a clue
3460 that they're special.
3462 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>

3505 * intervals.c (merge_interval_right, merge_interval_left):
3506 Do not zero out this interval if it is absorbed by its children,
3507 as this interval's total length doesn't change in that case. See
3508 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
3510 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
3512 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
3513 when invoking (make-bool-vector N t) and N is a positive

3517 * alloc.c (bool_header_size): New constant.
3518 (header_size, word_size): Move earlier, as they're now used earlier.

3521 padding before the data member of a bool vector.
3522 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
3523 than doing the check by hand with an abort ().
3525 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3527 * eval.c (Fdefvar): Don't check constants since we only set the var if
3528 it's not yet defined anyway (bug#11904).
3530 * lisp.h (last_undo_boundary): Declare new var.
3531 * keyboard.c (command_loop_1): Set it.
3532 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
3533 were auto-added by the command loop (bug#11774).
3535 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
3537 * w32font.c (Qsymbol): Remove local definition.

4036 Move CLASH_DETECTION to configure.
4038 * s/gnu.h: Remove file, which is now empty.
4040 * s/gnu.h, s/gnu-linux.h:
4041 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
4043 2012-07-11 John Wiegley <johnw@newartisans.com>
4045 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
4046 function attribute, so we only use it if it exists in the
4049 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
4051 Avoid call to strlen in fast_c_string_match_ignore_case.
4052 * search.c (fast_c_string_match_ignore_case): Change to use
4053 length argument. Adjust users accordingly.
4054 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
4056 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

4077 (font_open_by_name): Change to use length argument.
4078 Adjust users accordingly.
4079 * font.h (font_open_by_name, font_parse_xlfd, font_unparse_xlfd):
4081 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
4082 Change to return ptrdiff_t.
4083 (xfont_list_pattern, xfont_match): Use length returned by

4095 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
4097 Remove "#define unix" that is no longer needed (Bug#11905).
4098 * s/aix4-2.h (unix): Remove; no longer needed.
4100 EMACS_TIME simplification (Bug#11875).
4101 This replaces macros (which typically do not work in GDB)
4102 with functions, typedefs and enums, making the code easier to debug.
4103 The functional style also makes code easier to read and maintain.
4104 * systime.h: Include <sys/time.h> on all hosts, not just if
4105 WINDOWSNT, since 'struct timeval' is needed in general.
4106 (EMACS_TIME): Now a typedef, not a macro.
4107 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
4109 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

4111 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
4112 (EMACS_TIME_LE): Now functions, not macros.
4113 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
4114 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
4115 which are not functions. All uses rewritten to use:
4116 (make_emacs_time): New function.
4117 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
4118 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4119 not functions. All uses rewritten to use the following, respectively:
4120 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
4121 (add_emacs_time, sub_emacs_time): New functions.
4122 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
4123 * fileio.c (Fcopy_file):
4124 * xterm.c (XTflash): Get the current time closer to when it's used.
4125 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

4129 Simplify by avoiding confusing use of strncpy etc.
4130 * doc.c (Fsnarf_documentation):
4131 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
4132 * frame.c (Fmake_terminal_frame):
4133 * gtkutil.c (get_utf8_string):
4135 * nsmenu.m (ns_update_menubar):
4136 * regex.c (regerror):
4137 Prefer memcpy to strncpy and strncat when either will do.
4138 * fileio.c (Fsubstitute_in_file_name):
4139 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
4140 (menu_separator_name_p):
4141 * nsmenu.m (ns_update_menubar):
4142 Prefer memcmp to strncmp when either will do.
4143 * nsterm.m: Include <ftoastr.h>.
4145 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
4146 Prefer snprintf to strncpy.
4147 * nsterm.m (ns_term_init):
4148 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4149 * nsterm.m (ns_term_init):
4150 Avoid the need for strncpy, by using build_string or
4151 make_unibyte_string directly. Use dtoastr, not snprintf.
4152 * process.c (Fmake_network_process): Diagnose service names that
4153 are too long, rather than silently truncating them or creating
4154 non-null-terminated names.
4155 (Fnetwork_interface_info): Likewise, for interface names.
4156 * sysdep.c (system_process_attributes) [GNU_LINUX]:
4157 Prefer sprintf to strncat.
4158 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
4159 Prefer vsnprintf to vsprintf + strncpy.
4161 2012-07-10 Glenn Morris <rgm@gnu.org>
4163 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
4164 Clarify fallback case.
4166 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4168 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
4169 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
4170 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
4171 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
4172 where argument type is known to be a Lisp_Cons.
4174 2012-07-10 Tom Tromey <tromey@redhat.com>
4176 * bytecode.c (BYTE_CODE_THREADED): New macro.
4177 (BYTE_CODES): New macro. Replaces all old byte-code defines.
4178 (enum byte_code_op): New type.
4179 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.

4182 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4184 Optimize pure C strings initialization.
4185 * lisp.h (make_pure_string): Fix prototype.
4186 (build_pure_c_string): New function, defined as static inline. This
4187 provides a better opportunity to optimize away calls to strlen when
4188 the function is called with compile-time constant argument.
4189 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
4190 argument, adjust users accordingly. Use build_pure_c_string where
4192 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
4193 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
4194 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
4196 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4198 Avoid calls to strlen in miscellaneous functions.
4199 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
4200 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
4201 * lread.c (openp): Likewise.
4203 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4205 Avoid calls to strlen in path processing functions.
4206 * fileio.c (file_name_as_directory): Add comment. Change to add
4207 srclen argument and return the length of result. Adjust users
4209 (directory_file_name): Fix comment. Change to add srclen argument,
4210 swap 1st and 2nd arguments to obey the common convention.
4211 Adjust users accordingly.
4212 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
4214 2012-07-10 Glenn Morris <rgm@gnu.org>
4216 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
4217 Move PENDING_OUTPUT_COUNT definition to configure.
4219 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
4220 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
4221 * s/gnu.h (DATA_START): Move definitions to configure.
4223 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
4224 We include usg5-4-common.h, which defines them both.
4226 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
4227 O_RDONLY already includes it).
4229 Stop ns builds setting the EMACSLOADPATH environment variable.
4230 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4231 Now it does not set EMACSLOADPATH, just returns the load-path string.
4232 * nsterm.h: Update accordingly.
4233 * lread.c [HAVE_NS]: Include nsterm.h.
4234 (init_lread) [HAVE_NS]: Use ns_load_path.
4235 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
4237 2012-07-09 Glenn Morris <rgm@gnu.org>
4239 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
4240 since the included bsd-common.h does so.
4242 Stop ns builds setting the EMACSPATH environment variable.
4243 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
4244 (ns_init_paths): Do not set EMACSPATH.
4245 * nsterm.h (ns_exec_path): Add it.
4246 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
4249 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
4251 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
4253 * process.c (wait_reading_process_output): 'waitchannels' was unset
4254 when read_kbd || !NILP (wait_for_cell); fix this.
4256 Add GCC-style 'const' attribute to functions that can use it.
4257 * character.h (char_resolve_modifier_mask):
4258 * keyboard.h (make_ctrl_char):
4259 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
4260 (init_character_once, next_almost_prime, init_fns, init_image)
4261 (flush_pending_output, init_sound):
4262 * mem-limits.h (start_of_data):
4263 * menu.h (finish_menu_items):
4264 Add ATTRIBUTE_CONST.

4266 Declare the dummy function with ATTRIBUTE_CONST.
4267 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
4268 Add decls with ATTRIBUTE_CONST.
4270 Minor improvements to make_formatted_string.
4271 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
4272 where int is good enough, as vsprintf returns an int.
4273 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
4275 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4277 Use make_formatted_string to avoid double length calculation.
4278 * lisp.h (make_formatted_string): New prototype.
4279 * alloc.c (make_formatted_string): New function.
4280 * buffer.c (Fgenerate_new_buffer_name): Use it.
4281 * dbus.c (syms_of_dbusbind): Likewise.

4284 * frame.c (make_terminal_frame, set_term_frame_name)
4285 (x_report_frame_params): Likewise.
4286 * image.c (gs_load): Likewise.
4287 * minibuf.c (get_minibuffer): Likewise.

4302 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4304 Move marker debugging code under MARKER_DEBUG.
4305 * marker.c (MARKER_DEBUG): Move marker debugging code under
4306 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4307 for bootstrap with --enable-checking (~3x slowdown reported
4308 by Juanma Barranquero <lekktu@gmail.com>).
4309 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4311 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4313 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
4314 See <http://bugs.gnu.org/11825#29>.
4316 2012-07-08 Eli Zaretskii <eliz@gnu.org>
4318 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4319 has no font, use the frame's font. (Bug#11813)
4320 (display_line): Add commentary about displaying truncation glyphs
4322 (produce_special_glyphs): Move here from term.c.
4324 * term.c (produce_special_glyphs): Move to xdisp.c.
4326 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4329 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4331 * xdisp.c (display_line): Avoid warning about implicit declaration
4334 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4336 * lisp.h: Remove empty conditional.
4338 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4340 * lread.c (load_path_check): Now static.
4342 Fix some minor --with-ns problems found by static checking.
4343 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
4344 (x_set_font) [!HAVE_X_WINDOWS]:
4345 * image.c (xpm_load_image) [HAVE_NS]:
4346 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4347 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4348 Remove unused local.
4349 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
4350 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
4351 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
4352 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
4353 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
4354 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
4355 Fix pointer signedness problem.
4356 * xfaces.c (FRAME_X_FONT_TABLE):
4357 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
4359 2012-07-07 Glenn Morris <rgm@gnu.org>
4361 * lread.c (load_path_check): New function, split from init_lread.
4362 (init_lread): Reorganize. Motivation:
4363 If EMACSLOADPATH is set, check/warn about that rather than the
4364 defaults, which we are not going to use. Hence we can remove
4365 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4366 Don't warn if site-lisp directories are missing.
4367 If not installed, start from a blank load-path, since
4368 PATH_LOADSEARCH refers to the eventual installation directories.
4370 2012-07-07 Eli Zaretskii <eliz@gnu.org>
4372 Support truncation and continuation glyphs on GUI frames, when
4373 fringes are disabled. (Bug#11832)
4374 * xdisp.c (init_iterator): Get dimensions of truncation and
4375 continuation glyphs even if on GUI frames.
4376 Adjust it->last_visible_x on GUI frames when the left or right fringes,
4377 or both, are absent.
4378 (start_display, move_it_in_display_line_to): Handle the case of a
4379 GUI frame without a fringe to display continuation or truncation
4381 (insert_left_trunc_glyphs): Support GUI frames: make sure
4382 truncation glyphs overwrite enough glyphs from the current line to
4383 have sufficient space in pixels.
4384 (display_line): Support truncation and continuation glyphs on GUI
4385 frames. If some spare pixels are left on the line after inserting
4386 the truncation glyphs, fill that space with a stretch glyph of a
4387 suitably computed width.
4389 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4390 produce_glyphs, to support GUI sessions.
4392 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4394 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4396 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4398 Do not require float-time's arg to fit in time_t (Bug#11825).
4399 This works better on hosts where time_t is unsigned, and where
4400 float-time is applied to the (negative) difference between two times.
4401 * editfns.c (decode_time_components): Last arg is now double *,
4402 not int *, and means to store all the result as a double, without
4403 worrying about whether the seconds part fits in time_t.
4404 All callers changed.
4405 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4406 All callers changed.
4407 (Ffloat_time): Do not fail merely because the specified time falls
4408 outside of time_t range.
4410 2012-07-07 Glenn Morris <rgm@gnu.org>
4412 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
4413 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

4416 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
4418 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
4419 Update dependencies.
4421 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
4423 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4425 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
4426 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
4427 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
4428 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
4429 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
4430 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
4432 * xfont.c (compare_font_names): Redo to omit the need for casts.
4434 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4436 * xfns.c (Fx_change_window_property): Doc fix.
4437 * w32fns.c (Fx_change_window_property): Doc fix.
4439 * w32fns.c (Fx_window_property): Accept the same arguments as the
4440 X Windows version. Doc fix.
4441 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4443 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4444 Eli Zaretskii <eliz@gnu.org>
4446 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4447 Windows-specific code from nt/config.nt moved here.
4448 Obsolete settings removed.
4450 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4452 * process.c: Avoid unnecessary calls to gettime.
4453 (wait_reading_process_output): Don't get the time of day
4454 when gobbling data immediately and not waiting, as there's no need
4455 for it in that case. This removes a FIXME.
4457 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4459 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4460 is defined (Bug#11768).
4462 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4464 Fix marker debugging code.
4465 * marker.c (byte_char_debug_check): Do not perform the check
4466 if buffer is not multibyte.
4467 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4468 Call byte_char_debug_check with correct arguments.
4470 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4472 Compile marker debugging code only if ENABLE_CHECKING is defined.
4473 * marker.c (byte_char_debug_check, count_markers):
4474 Use only if ENABLE_CHECKING is defined.
4475 (byte_debug_flag): Remove.
4476 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4477 Always call byte_char_debug_check if ENABLE_CHECKING is defined.

4481 Avoid code repetition in marker-related functions.
4482 * marker.c (attach_marker): New function.
4483 (Fset_marker, set_marker_restricted, set_marker_both)
4484 (set_marker_restricted_both): Use it.
4485 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4486 Consistently rename charno to charpos.
4487 (marker_position): Add eassert.
4488 (marker_byte_position): Convert to eassert.
4490 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4492 Simplify list operations in unchain_overlay and unchain_marker.
4493 * buffer.c (unchain_overlay): Simplify. Add comment.
4494 * marker.c (unchain_marker): Simplify. Fix comments.
4496 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4498 Introduce fast path for the widely used marker operation.
4499 * alloc.c (build_marker): New function.
4500 * lisp.h (build_marker): New prototype.
4501 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
4502 * composite.c (autocmp_chars): Likewise.
4503 * editfns.c (buildmark): Remove.
4504 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
4505 (save_restriction_save): Use build_marker.
4506 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
4507 * window.c (save_window_save): Likewise.
4509 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

4512 to avoid redundant calls to unchain_overlay.
4513 * buffer.c (drop_overlay): New function.
4514 (delete_all_overlays, Fdelete_overlay): Use it.
4515 * minibuf.c (get_minibuffer): Fix comment.
4517 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4519 Port to OpenBSD 5.1 amd64.
4520 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4521 This is needed for OpenBSD, and should be harmless on all BSD systems.
4522 Also, include <sys/sysctl.h>, as it should be available on all
4523 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4524 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4525 use p_pid member, not kp_proc.pid.
4527 2012-07-06 Glenn Morris <rgm@gnu.org>
4529 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4531 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4533 More xmalloc and related cleanup.
4534 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

4541 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
4542 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4544 Omit needless casts involving void * pointers and allocation.
4545 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4546 as the former is more robust if P's type is changed.
4547 Prefer xzalloc to xmalloc + memset 0.
4548 Simplify malloc-or-realloc to realloc.
4549 Don't worry about xmalloc returning a null pointer.
4550 Prefer xstrdup to xmalloc + strcpy.
4551 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4553 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4554 alloca of a constant.
4556 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4558 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4559 hscroll is larger than the line width. Fixes long and futile
4560 looping inside extend_face_to_end_of_line (on a TTY) producing
4561 glyphs that are not needed and thrown away.
4563 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4565 * marker.c (set_marker_restricted_both): Simplify by using
4568 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4570 * editfns.c (region_limit): Simplify by using clip_to_bounds.
4572 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
4574 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
4575 not defined (Bug#11768).
4576 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
4577 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
4578 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
4579 followed by gtk_box_set_homogeneous (Bug#11768).
4580 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4581 (update_theme_scrollbar_width, xg_create_scroll_bar):
4582 Use gtk_scrollbar_new (Bug#11768).
4583 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
4584 (is_box_type): New function (Bug#11768).
4585 (xg_tool_item_stale_p): Call is_box_type.
4586 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
4587 with default display (Bug#11768).

4591 * xdisp.c (window_hscroll_limited): New function.
4592 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
4593 coordinates when window's hscroll is set to insanely large
4596 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
4598 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

4604 * lisp.h (xzalloc): New prototype. Omit needless casts.
4605 * alloc.c (xzalloc): New function. Omit needless casts.
4606 * charset.c: Omit needless casts. Convert all calls to
4607 xmalloc with following memset to xzalloc.

4657 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4659 * fileio.c (time_error_value): Check the right error number.
4660 Problem reported by Troels Nielsen in
4661 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
4663 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4665 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
4666 This should be fixed in a better way; see Eli Zaretskii in
4667 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
4668 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
4670 * fileio.c (time_error_value): Rename from special_mtime.
4671 The old name's problems were noted by Eli Zaretskii in
4672 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
4674 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
4675 This variable's comment says Emacs needs at least one GDB-visible
4676 symbol of type enum pvec_type, to work around GDB problems.
4677 The symbol's value doesn't matter.
4679 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
4680 that causes compilation to fail on pre-C99 compilers.
4682 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
4684 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
4685 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
4687 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4689 * buffer.c (init_buffer_once): Fix initialization of
4690 headers for buffer_defaults and buffer_local_symbols.
4691 Reported by Juanma Barranquero <lekktu@gmail.com>.
4693 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
4695 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
4696 * lisp.h (enum pvec_type): Use fewer bits.
4697 (PSEUDOVECTOR_SIZE_BITS): New constant.
4698 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
4699 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
4700 change in pvec_type.
4701 (PSEUDOVECTOR_TYPEP): New macro.
4702 (TYPED_PSEUDOVECTORP): Use it.
4703 * fns.c (internal_equal): Adapt code to extract pvectype.

4707 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
4708 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
4709 (sweep_vectors): Use it. Use local var `total_bytes' instead of
4710 abusing vector->header.next.nbytes.
4711 (live_vector_p): Use PVEC_TYPE.
4712 (mark_object): Adapt code to extract pvectype. Use switch.
4714 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4716 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
4717 Tighten new eassert a bit.
4719 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4721 Fix compilation with --enable-gcc-warnings and -O1
4723 * doprnt.c (doprnt): Change type of tem to int, initialize
4724 to avoid compiler warning. Add eassert.
4725 * search.c (simple_search): Initialize match_byte to avoid
4726 compiler warning. Add eassert.
4728 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4730 Avoid weird behavior with large horizontal scrolls.
4731 Without this change, for example, large hscroll values would
4732 mess up Emacs's display on Fedora 15 x86, presumably due to
4733 overflows in int calculations in the display code.
4734 Also, if buffers had long lines, Emacs would freeze.
4735 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
4736 (set_window_hscroll): New function, containing the old guts of
4737 Fset_window_hscroll. Return the clipped value.
4738 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
4739 This avoids the need to check against PTRDIFF_MAX.
4741 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
4743 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4745 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
4747 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4749 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
4750 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
4751 since GCC 4.4.6 issues a bogus warning for them.
4753 Fix bugs in file timestamp newness comparisons.
4754 * fileio.c (Ffile_newer_than_file_p):
4755 * lread.c (Fload): Use full timestamp resolution of files,
4756 not just the 1-second resolution, so that files that are only
4757 slightly newer still count as newer.
4758 * fileio.c (Ffile_newer_than_file_p): Don't assume file
4759 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
4761 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
4763 * fileio.c: Improve handling of file time marker. (Bug#11852)
4764 (special_mtime): New function.
4765 (Finsert_file_contents, Fverify_visited_file_modtime):
4766 Use it to set special mtime values consistently.
4768 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
4770 * fileio.c (Finsert_file_contents): Properly handle st_mtime
4771 marker for non-existing file. (Bug#11852)
4773 2012-07-03 Glenn Morris <rgm@gnu.org>
4775 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
4776 and did not make it into globals.h).
4778 2012-07-03 Tom Tromey <tromey@redhat.com>
4780 * window.c (Fset_window_margins, Fset_window_fringes)
4781 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
4782 * textprop.c (Fprevious_property_change): No longer static.
4783 * syntax.c (Fsyntax_table_p): No longer static.
4784 * process.c (Fget_process, Fprocess_datagram_address): No longer

4798 * dired.c (Ffile_attributes): No longer static.
4799 * composite.c (Fcomposition_get_gstring): No longer static.
4800 * callproc.c (Fgetenv_internal): No longer static.
4802 * ccl.h: Remove EXFUNs.
4803 * buffer.h: Remove EXFUNs.
4804 * dispextern.h: Remove EXFUNs.
4805 * intervals.h: Remove EXFUNs.
4806 * fontset.h: Remove EXFUN.
4807 * font.h: Remove EXFUNs.
4808 * dosfns.c (system_process_attributes): Remove EXFUN.
4809 * keymap.h: Remove EXFUNs.
4810 * lisp.h: Remove EXFUNs.
4811 * w32term.h: Remove EXFUNs.
4812 * window.h: Remove EXFUNs.
4813 * xsettings.h: Remove EXFUN.
4814 * xterm.h: Remove EXFUN.
4816 2012-07-03 Glenn Morris <rgm@gnu.org>
4818 * lisp.h (Frandom): Make it visible to C.
4819 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
4820 buffer for invisible buffers. (Bug#1229)
4822 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4824 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
4825 values which aren't power of 2.
4826 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
4827 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
4830 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
4832 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
4834 * alloc.c (mark_object): Revert part of last patch to use `switch'.
4836 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4838 * alloc.c (allocate_vector_block): Remove redundant
4839 calls to mallopt if DOUG_LEA_MALLOC is defined.
4840 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
4841 avoid calls to mallopt if zero_vector is returned.
4843 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4845 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
4846 is enabled, avoid dereferencing NULL current_sblock if
4849 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4851 Cleanup basic buffer management.
4852 * buffer.h (struct buffer): Change layout to use generic vector
4853 marking code. Fix some comments. Change type of 'clip_changed'
4854 to bitfield. Remove unused #ifndef old.
4855 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
4856 (GET_OVERLAYS_AT): Fix indentation.
4857 (for_each_per_buffer_object_at): New macro.
4858 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
4859 (Fbuffer_local_variables): Use it.
4860 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
4861 * alloc.c (allocate_buffer): Adjust to match new layout of
4862 struct buffer. Fix comment.
4863 (mark_overlay): New function.
4864 (mark_buffer): Use it. Use mark_vectorlike to mark normal
4865 Lisp area of struct buffer.
4866 (mark_object): Use it. Adjust marking of misc objects
4867 and related comments.
4869 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
4871 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
4872 wrapper that is not needed because the wrapped code is a no-op (zero
4873 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
4874 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
4876 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
4878 * alloc.c (mark_buffer): Simplify. Remove prototype.
4879 (mark_object): Add comment. Reorganize marking of vector-like
4880 objects. Use CHECK_LIVE for all vector-like objects except buffers
4881 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
4882 Avoid redundant calls to mark_vectorlike for bool vectors.
4884 2012-06-30 Glenn Morris <rgm@gnu.org>
4886 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
4888 * epaths.in (PATH_SITELOADSEARCH): New.
4889 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
4890 This is rather than relying on --enable-locallisppath elements
4891 having "site-lisp" in their names. (Bug#10208#25, 11658)
4893 2012-06-30 Eli Zaretskii <eliz@gnu.org>
4895 * w32proc.c (sys_select): Accept and ignore one more argument.
4897 * w32.c (emacs_gnutls_pull): Call select with one more argument.
4899 * sysselect.h [DOS_NT]: Don't include sys/select.h.
4900 (pselect) [!MS_DOS]: Redirect to sys_select.
4902 * sysdep.c: Don't include dos.h and dosfns.h.
4904 * process.c (sys_select):
4905 * msdos.c (sys_select): Accept one more argument and ignore it.
4907 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
4908 adapt data types and code to that.
4911 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
4912 which clashes with the gnulib function of the same name.
4914 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
4916 * font.c (font_style_to_value, font_style_symbolic)
4917 (font_prop_validate_style): Add type checks for values in
4920 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
4922 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
4925 2012-06-29 Eli Zaretskii <eliz@gnu.org>
4927 * xdisp.c (try_window_id): Undo last change.
4929 * w32.c (getwd): Adjust commentary about startup_dir.
4930 (init_environment): Always call sys_access, even in non-MSVC
4931 builds. Don't chdir to the directory of the Emacs executable.
4932 This undoes code from 1997 which was justified by the need to
4933 "avoid conflicts when removing and renaming directories". But its
4934 downside was that every relative file name was being interpreted
4935 relative to the directory of the Emacs executable, which can never
4936 be TRT. In particular, it broke sys_access when called with
4937 relative file names.
4938 (sys_access): Map GetLastError to errno.
4940 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4942 * window.h (struct window): Change type of 'fringes_outside_margins'
4943 to bitfield. Fix comment. Adjust users accordingly.
4944 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
4946 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
4949 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

5132 Use sprintf return value instead of invoking strlen on result.
5133 In the old days this wasn't portable, since some sprintf
5134 implementations returned char *. But they died out years ago and
5135 Emacs already assumes sprintf returns int.
5136 Similarly for float_to_string.
5137 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

5145 Use sprintf or float_to_string result to avoid need to call strlen.
5146 * data.c (Fnumber_to_string):
5147 Use make_unibyte_string, since the string must be ASCII.
5148 * lisp.h, print.c (float_to_string): Now returns int length.
5149 * term.c (produce_glyphless_glyph):
5150 Use sprintf result rather than recomputing it.
5152 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
5153 * Makefile.in (ALL_CFLAGS):
5154 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

5183 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
5185 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

5188 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
5190 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
5191 instead of truncating it to 63 (admittedly a generous limit).

5251 * keyboard.c (kbd_buffer_get_event):
5252 * process.c (Faccept_process_output):
5253 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
5254 This improves on the previous patch, which introduced a bug
5255 when time_t is unsigned and as wide as intmax_t.
5256 See <http://bugs.gnu.org/9000#51>.
5258 2012-06-23 Eli Zaretskii <eliz@gnu.org>

5321 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5323 Support higher-resolution time stamps (Bug#9000).
5324 The time stamps are only nanosecond-resolution at the C level,
5325 since that's the best that any real-world system supports now.
5326 But they are picosecond-resolution at the Lisp level, as that's
5327 easy, and leaves room for future OS improvements.
5329 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5332 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5333 Don't get current time unless it's needed.
5335 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5336 now provides it if it's absent.
5337 (start_atimer): Port to higher-res time stamps.
5338 Check for time stamp overflow. Don't get current time more
5339 often than is needed.
5341 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5342 Include systime.h, not time.h.
5343 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
5345 * dired.c: Include stat-time.h.
5346 (Ffile-attributes): File times now have higher resolution.

5349 (struct image): Timestamp now has higher resolution.
5351 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5352 has at least microseconds now. All uses removed.
5353 (update_frame, update_single_window, update_window, update_frame_1)
5354 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5355 (duration_to_sec_usec): Remove; no longer needed.
5357 * editfns.c (time_overflow): Now extern.
5358 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
5359 (float-time, Fformat_time_string, Fcurrent_time_string)
5360 (Fcurrent_time_zone): Accept and generate higher-resolution

5363 (decode_time_components, lisp_seconds_argument): New functions.
5364 (make_time): Now static.
5365 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
5366 Report an error if the time is invalid, rather than having the caller
5369 * fileio.c: Include <stat-time.h>
5370 (Fcopy_file): Copy higher-resolution time stamps.
5371 Prefer to set the time stamp via a file descriptor if that works.
5372 (Fset_file_times, Finsert_file_contents, Fwrite_region)
5373 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
5374 (Fvisited_file_modtime, Fset_visited_file_modtime):
5375 Support higher-resolution time stamps.
5377 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
5379 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
5381 * image.c (prepare_image_for_display, clear_image_cache)
5382 (lookup_image): Port to higer-resolution time stamps.
5384 * keyboard.c (start_polling, bind_polling_period):
5385 Check for time stamp overflow.
5386 (read_char, kbd_buffer_get_event, timer_start_idle)
5387 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
5388 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5389 Port to higher-resolution time stamps. Do not assume time_t is signed.
5390 (decode_timer): New function. Timers are now vectors of length 9,
5391 not 8, to accommodate the picosecond component.
5392 (timer_check_2): Use it.
5394 * nsterm.m (select_timeout, timeval_subtract): Remove.
5395 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5396 as they're a bit more accurate and handle overflow better.
5397 (ns_select): Change prototype to be compatible with pselect.
5398 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5399 * nsterm.h (ns_select): Adjust prototype.
5401 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5402 us-resolution time stamps.
5403 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5405 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5407 * lisp.h (time_overflow): New decl.
5408 (wait_reading_process_output): First arg is now intmax_t, not int,
5409 to accommodate larger waits.
5411 * process.h (struct Lisp_Process.read_output_delay):
5412 Now counts nanoseconds, not microseconds.
5413 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
5415 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
5416 (wait_reading_process_output):
5417 Port to ns-resolution time stamps.
5418 (Faccept_process_output, wait_reading_process_output):
5419 Check for time stamp overflow. Do not assume time_t is signed.
5420 (select_wrapper): Remove; we now use pselect.
5421 (Fprocess_attributes): Now generates ns-resolution time stamps.
5423 * sysdep.c: Include utimens.h. Don't include utime.h
5424 or worry about struct utimbuf; gnulib does that for us now.
5425 (gettimeofday): Remove; gnulib provides a substitute.
5426 (make_timeval): New function.
5427 (set_file_times): Now sets ns-resolution time stamps.
5428 New arg FD; all uses changed.
5429 (time_from_jiffies, ltime_from_jiffies, get_up_time)
5430 (system_process_attributes):
5431 Now returns ns-resolution time stamp. All uses changed.
5432 Check for time stamp overflow.
5434 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5435 provides a substitute now.
5437 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5438 since it guarantees struct timespec.
5439 (EMACS_TIME): Now struct timespec, so that we can support
5440 ns-resolution time stamps.
5441 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5442 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5443 (EMACS_USECS): Remove.
5444 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,

5448 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

5455 (make_timeval, make_lisp_time, decode_time_components): New decls.
5456 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
5457 that it mishandled time_t overflow. You can't compare by subtracting!
5458 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
5459 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

5498 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5499 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,

5550 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
5551 gets killed during executing of this function (Bug#11665).
5552 Try to always return Qt when the buffer has been actually killed.
5553 (Vkill_buffer_query_functions): In doc-string say that functions
5554 run by this hook should not change the current buffer.
5556 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

5581 argument were confusing, as 'eassert' typically does not evaluate
5584 * coding.c (produce_chars): Use ptrdiff_t, not int.
5586 * xterm.c (x_draw_underwave): Check for integer overflow.
5587 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

5909 0 items. Allocate new vector from block if vector size is less than
5910 or equal to VBLOCK_BYTES_MAX.
5911 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
5912 (init_alloc_once): Add call to init_vectors.
5914 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
5916 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
5918 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
5920 * doprnt.c (doprnt): Truncate multibyte char correctly.
5921 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
5922 would mishandle a string argument "Xc" if X was a multibyte
5923 character of length 2: it would truncate after X's first byte
5924 rather than including all of X.
5926 2012-06-06 Chong Yidong <cyd@gnu.org>
5928 * buffer.c (word_wrap): Doc fix.
5930 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>
5932 * xdisp.c (note_mode_line_or_margin_highlight): Pacify gcc -Wall.

5948 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
5951 2012-06-03 Chong Yidong <cyd@gnu.org>
5953 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
5954 (note_mode_line_or_margin_highlight): If there is no help echo,
5955 use mode-line-default-help-echo. Handle the case where the mouse
5956 position is past the end of the mode line string.
5958 * buffer.c (buffer_local_value_1): New function, split from
5959 Fbuffer_local_value; can return Qunbound.
5960 (Fbuffer_local_value): Use it.
5961 (Vmode_line_format): Docstring tweaks.
5963 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5965 * sysdep.c (system_process_attributes): Improve comment.
5967 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
5969 * keyboard.c: Export real-this-command to Elisp.
5970 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
5971 and DEFVAR it. Update all users.
5973 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5975 * minibuf.c (Fassoc_string): Remove duplicate declaration.
5977 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
5978 Convert pctcpu and pctmem to Lisp float properly.
5979 Let the compiler fold better, as 100.0/0x8000 is exact.
5981 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
5983 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
5986 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
5988 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
5990 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
5992 For a 'struct window', replace some Lisp_Object fields to
5993 bitfields where appropriate, remove unused fields.
5994 * window.h (struct window): Remove unused 'last_mark_x' and
5995 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
5996 change it's type from Lisp_Object to bitfield.
5997 Change type of 'force_start', 'optional_new_start',
5998 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
5999 fields from Lisp_Object to bitfield. Adjust users accordingly.
6001 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6003 Pacify gcc -Wdouble-precision when using Xaw.
6004 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
6005 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
6006 Use 'float' consistently, rather than 'float' in most places
6007 and 'double' in a couple of places.
6009 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6011 * xdisp.c (handle_stop): Detect whether we have overlay strings
6012 loaded by testing it->current.overlay_string_index to be
6013 non-negative, instead of checking whether n_overlay_strings is
6014 positive. (Bug#11587)
6016 2012-05-31 Chong Yidong <cyd@gnu.org>
6018 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
6020 * doc.c (Fsubstitute_command_keys): Doc fix.
6022 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6024 * search.c (search_buffer): Remove calls to
6025 r_alloc_inhibit_buffer_relocation, as it is now called by
6026 maybe_unify_char, which was the cause of relocation of buffer text
6029 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6031 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6032 for the duration of call to load_charset, to avoid problems with
6033 callers of maybe_unify_char that access buffer text through C
6036 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6037 decrement the inhibition flag, instead of just setting or
6040 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6042 Remove obsolete '#define static' cruft.
6043 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6044 This #undef was "temporary" in 2000; it is no longer needed
6045 now that '#define static' has gone away.
6046 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6047 (gray_bitmap_bits): Remove; no longer needed.
6048 All uses replaced with definiens.
6049 * xterm.c: Include "bitmaps/gray.xbm".
6051 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6053 Clean up __executable_start, monstartup when --enable-profiling.
6054 The following changes affect the code only when profiling.
6055 * dispnew.c (__executable_start): Rename from safe_bcopy.
6056 Define only on platforms that need it.
6057 * emacs.c: Include <sys/gmon.h> when profiling.
6058 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6059 (__executable_start): Remove decl, since lisp.h does it now.
6060 (safe_bcopy): Remove decl; no longer has that name.
6061 (main): Coalesce #if into single bit of code, for simplicity.
6062 Cast pointers to uintptr_t, since standard libraries want integers
6064 * lisp.h (__executable_start): New decl.
6066 2012-05-31 Glenn Morris <rgm@gnu.org>
6068 * image.c (Fimagemagick_types): Doc fix.
6070 2012-05-30 Jim Meyering <meyering@redhat.com>
6072 * callproc.c (Fcall_process_region): Include directory component
6073 in mkstemp error message (Bug#11586).
6075 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6077 * alloc.c, lisp.h (make_pure_vector): Now static.
6079 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

6082 Move to byte-run.el.
6083 (Fautoload): Do the hash-doc more carefully.
6084 * data.c (Fdefalias): Purify definition, except for keymaps.
6085 (Qdefun): Move from eval.c.
6086 * lisp.h (Qdefun): Remove.
6087 * lread.c (read1): Tiny simplification.
6089 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
6091 Do not create empty overlays with the evaporate property (Bug#9642).
6092 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6093 Bug#9642, but explicitly check that the buffer the overlay would
6094 be moved to is live and rearrange lines to make sure that errors
6095 will not put the overlay in an inconsistent state.
6096 (Fdelete_overlay): Cosmetics.
6098 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6100 * w32term.c (my_bring_window_to_top): New function.
6101 (x_raise_frame): Use handle returned by DeferWindowPos, which
6102 could be different from the original one.
6103 Call my_bring_window_to_top instead of my_set_foreground_window.
6106 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6107 by calling BringWindowToTop.
6109 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6110 (WM_EMACS_END): Increase by one.
6112 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6114 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6115 This avoids undefined behavior that might cause the eassert
6116 to not catch an out-of-range value.
6118 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6120 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
6121 Update dependencies.
6123 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6125 * bidi.c (bidi_mirror_char): Fix last change.
6127 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
6129 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
6130 when referring to sectname field in printf format.
6132 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
6134 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6135 Only r_alloc_inhibit_buffer_relocation needed to be added;
6136 the others were already declared.
6138 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6139 before checking whether it's out of range. Put the check inside
6141 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6143 2012-05-27 Ken Brown <kbrown@cornell.edu>
6145 * callproc.c (Fcall_process): Restore a line that was accidentally
6146 commented out in the 2011-02-13 change (bug#11547).
6148 2012-05-27 Eli Zaretskii <eliz@gnu.org>
6150 * lisp.h [REL_ALLOC]: Add prototypes for external functions
6151 defined on ralloc.c.
6153 * buffer.c [REL_ALLOC]: Remove prototypes of
6154 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
6155 they are now on lisp.h.
6157 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6159 * search.c (search_buffer): Use it to inhibit relocation of buffer
6160 text while re_search_2 is doing its job, because re_search_2 is
6161 passed C pointers to buffer text. (Bug#11519)
6163 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6166 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6167 state after an additional call to move_it_in_display_line_to, keep
6168 the values of it->max_ascent and it->max_descent found for the
6170 (pos_visible_p): Revert the comparison against bottom_y to what it
6171 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
6174 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6176 Fix coding-related core dumps with gcc -ftrapv.
6177 The code was computing A - B, where A and B are pointers, and B is
6178 random garbage. This can lead to core dumps on platforms that
6179 have special pointer registers, and it also leads to core dumps on
6180 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6181 A - B only when B is initialized properly.
6182 * coding.c (coding_set_source, coding_set_destination): Return void.
6183 (coding_change_source, coding_change_destinations): New functions,
6184 with the old behaviors of coding_set_source and coding_set_destination.
6185 All callers that need an offset changed to use these new functions.
6187 2012-05-26 Glenn Morris <rgm@gnu.org>
6189 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
6191 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6193 Extend mouse support on W32 text-mode console.
6194 * xdisp.c (draw_row_with_mouse_face):
6195 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6197 * w32console.c: Include window.h.
6198 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6200 (initialize_w32_display): Initialize mouse-highlight data.
6202 * w32inevt.c: Include termchar.h and window.h.
6203 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6204 moves, call note_mouse_highlight. If help_echo changed, call
6205 gen_help_event to produce help-echo message in the echo area.
6206 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6209 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6211 * lread.c (read1): Simplify slightly to avoid an overflow warning
6212 with GCC 4.7.0 on x86-64.
6214 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6216 * bidi.c (bidi_mirror_char): Revert last change: an int is
6217 definitely wide enough here.
6219 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
6221 Fix integer width and related bugs (Bug#9874).
6222 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
6223 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
6224 (string_bytes, check_sblock, allocate_string_data):
6225 (compact_small_strings, Fmake_bool_vector, make_string)
6226 (make_unibyte_string, make_multibyte_string)
6227 (make_string_from_bytes, make_specified_string)
6228 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
6229 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
6231 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6232 (allocate_pseudovector):
6233 Use int, not EMACS_INT, where int is wide enough.
6234 (inhibit_garbage_collection, Fgarbage_collect):
6235 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6236 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
6237 int might not be wide enough.
6238 (bidi_cache_search, bidi_cache_find, bidi_init_it)
6239 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6240 (bidi_at_paragraph_end, bidi_find_paragraph_start)
6241 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
6242 (bidi_level_of_next_char, bidi_move_to_visually_next):
6243 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6244 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
6245 (Fkill_buffer, Fset_buffer_major_mode)
6246 (advance_to_char_boundary, Fbuffer_swap_text)
6247 (Fset_buffer_multibyte, overlays_at, overlays_in)
6248 (overlay_touches_p, struct sortvec, record_overlay_string)
6249 (overlay_strings, recenter_overlay_lists)
6250 (adjust_overlays_for_insert, adjust_overlays_for_delete)
6251 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
6252 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
6253 (Foverlay_recenter, last_overlay_modification_hooks_used)
6254 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6255 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6256 (validate_region): Omit unnecessary test for b <= e,
6257 since that's guaranteed by the previous test.
6258 (adjust_overlays_for_delete): Avoid pos + length overflow.
6259 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6260 (report_overlay_modification):
6261 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6262 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
6263 Omit pointer cast, which isn't needed anyway, and doesn't work
6264 after the EMACS_INT -> ptrdiff_t change.
6265 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
6266 * buffer.h: Adjust decls to match defn changes elsewhere.
6267 (struct buffer_text, struct buffer):
6268 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6269 Use EMACS_INT, not int, where int might not be wide enough.
6270 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
6271 not int, to avoid needless 32-bit limit on 64-bit hosts.
6272 (exec_byte_code): Use tighter memory-full test, one that checks
6273 for alloca overflow. Don't compute the address of the object just
6274 before an array, as that's not portable. Use EMACS_INT, not
6275 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
6276 * callint.c (Fcall_interactively):
6277 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6278 * callproc.c (call_process_kill, Fcall_process):
6279 Don't assume pid_t fits into an Emacs fixnum.
6280 (call_process_cleanup, Fcall_process, child_setup):
6281 Don't assume pid_t fits into int.
6282 (call_process_cleanup, Fcall_process, delete_temp_file)
6283 (Fcall_process_region):
6284 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6285 (Fcall_process): Simplify handling of volatile integers.
6286 Use int, not EMACS_INT, where int will do.
6287 * casefiddle.c (casify_object, casify_region, operate_on_word)
6288 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
6289 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6290 (casify_object): Avoid integer overflow when overallocating buffer.
6291 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
6292 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
6293 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
6294 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6295 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6296 integers are now checked earlier. All uses replaced with XINT.
6298 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6299 For CCL_MapSingle, check that content and value are in int range.
6300 (ccl_driver, Fregister_code_conversion_map):
6301 Check that Vcode_version_map_vector is a vector.
6302 (resolve_symbol_ccl_program): Check that vector header is in range.
6303 Always copy the vector, so that we can check its contents reliably
6304 now rather than having to recheck each instruction as it's being
6305 executed. Check that vector words fit in 'int'.
6306 (ccl_get_compiled_code, Fregister_ccl_program)
6307 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6308 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
6309 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
6310 contents are in range.
6311 (Fccl_execute_on_string): Check that status is in range.
6312 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
6313 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
6314 Accept and return EMACS_INT, not int, because callers can pass values
6316 (c_string_width, strwidth, lisp_string_width, chars_in_text)
6317 (multibyte_chars_in_text, parse_str_as_multibyte)
6318 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
6319 (str_as_unibyte, str_to_unibyte, string_count_byte8)
6320 (string_escape_byte8, Fget_byte):
6321 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6322 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
6323 avoid mishandling large integers.
6324 * character.h: Adjust decls to match defn changes elsewhere.
6325 * charset.c (load_charset_map_from_file, find_charsets_in_text)
6326 (Ffind_charset_region):
6327 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6328 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
6329 (load_charset_map_from_vector, Fdefine_charset_internal):
6330 Don't assume fixnum fits in int.
6331 (load_charset_map_from_vector, Fmap_charset_chars):
6332 Remove now-unnecessary CHECK_NATNUMs.
6333 (Fdefine_charset_internal): Check ranges here, more carefully.
6334 Don't rely on undefined behavior with signed left shift overflow.
6335 Don't assume unsigned int fits into fixnum, or that fixnum fits
6336 into unsigned int. Don't require max_code to be a valid fixnum;
6337 that's not true for gb10830 4-byte on a 32-bit host. Allow
6338 invalid_code to be a cons, for the same reason. Require code_offset
6339 to be a character. Avoid int overflow if max_char is close
6341 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
6342 this is intended anyway and avoids some undefined behavior.
6343 (load_charset_map): Pass unsigned, not int, as 2nd arg of
6344 INDEX_TO_CODE_POINT, as that's what it expects.
6345 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
6346 * charset.h (DECODE_CHAR): Return int, not unsigned;
6347 this is what was intended anyway, and it avoids undefined behavior.
6348 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
6349 integer-overflow issues.

7058 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
7059 (EMACS_UINT): Define unconditionally now.
7060 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
7061 (BITS_PER_EMACS_INT): New constants, replacing
7062 what used to be in config.h, but not useful in #if.
7063 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
7064 define them any more.
7065 (VAL_MAX): New macro.
7067 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
7068 BITS_PER_EMACS_INT, in #if.
7069 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
7070 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
7071 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
7072 * s/ms-w32.h (DATA_START):
7073 Move here from removed file m/intel386.h.
7074 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
7075 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
7077 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
7079 Assume C89 or later.
7080 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
7081 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
7083 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
7084 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
7085 * textprop.c, tparam.c (NULL): Remove.
7086 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
7087 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
7088 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
7089 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
7090 * xterm.c (input_signal_count): Assume volatile works.
7092 2012-05-21 Ken Brown <kbrown@cornell.edu>
7094 * xgselect.c (xg_select): Fix first argument in call to 'select'
7097 2012-05-20 Ken Brown <kbrown@cornell.edu>
7099 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
7100 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
7102 2012-05-19 Ken Brown <kbrown@cornell.edu>
7104 * xfns.c (x_in_use): Remove `static' qualifier.
7105 * xterm.h (x_in_use): Declare.
7106 * xgselect.c: Include xterm.h.
7107 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
7108 and `display_arg' (bug#9754).
7110 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
7112 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
7114 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
7115 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
7117 2012-05-18 Eli Zaretskii <eliz@gnu.org>
7119 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
7121 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
7122 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
7124 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
7125 reference to image_cache->refcount.
7126 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
7128 2012-05-17 Juri Linkov <juri@jurta.org>
7130 * search.c (Fword_search_regexp, Fword_search_backward)
7131 (Fword_search_forward, Fword_search_backward_lax)
7132 (Fword_search_forward_lax): Move functions to isearch.el
7133 (bug#10145, bug#11381).
7135 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
7137 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
7139 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
7141 * lread.c (init_obarray): Declare Qt and Qnil as special.
7143 2012-05-14 Glenn Morris <rgm@gnu.org>
7145 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
7146 Put "libexec" before "bin", for the sake of init_callproc_1.
7148 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7150 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
7152 * unexaix.c: Port to more-recent AIX compilers.
7153 (report_error, report_error_1, make_hdr, copy_sym)
7154 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
7155 Make arguments const char *, not char *, to avoid violations of C
7156 standard and to fix some AIX warnings reported by Gilles Pion.
7158 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7160 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
7161 already have overlays loaded.
7162 (handle_single_display_spec): Before returning without displaying
7163 fringe bitmap, synchronize the bidi iterator with the main display
7164 iterator, by calling iterate_out_of_display_property.
7165 (iterate_out_of_display_property): Detect buffer iteration by
7166 testing that it->string is a Lisp string.
7167 (get_next_display_element): When the current object is exhausted,
7168 and there's something on it->stack, call set_iterator_to_next to
7169 proceed with what's on the stack, instead of returning zero.
7170 (set_iterator_to_next): If called at the end of a Lisp string,
7171 proceed to consider_string_end without incrementing string
7172 position. Don't increment display vector index past the end of
7173 the display vector. (Bug#11417)
7174 (pos_visible_p): Don't report a position visible when move_it_to
7175 stopped at the last line of window, which happens to be scanned
7176 backwards by the bidi iteration. (Bug#11464)
7178 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7180 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7181 and right-margin display specs even if the spec is invalid or we
7182 are on a TTY, and thus unable to display on the fringes.
7183 That's because the text with the property will not be displayed anyway,
7184 so we need to signal to the caller that this is a "replacing"
7185 display spec. This fixes display when the spec is invalid or we
7188 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7190 * unexaix.c (make_hdr): Fix typo in prototype.
7191 This bug broke the build on AIX. Problem reported by Gilles Pion.
7193 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
7195 * keyboard.c (kbd_buffer_get_event): Read special events also in
7196 batch mode. (Bug#11415)
7198 2012-05-12 Glenn Morris <rgm@gnu.org>
7200 * ns.mk: Update for ns_appbindir no longer having trailing "/".
7202 2012-05-12 Eli Zaretskii <eliz@gnu.org>
7204 * lisp.mk (lisp): Add newcomment.elc.
7206 2012-05-12 Glenn Morris <rgm@gnu.org>
7208 * Makefile.in (MKDIR_P): New, set by configure.
7209 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
7211 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
7213 Remove unused function hourglass_started.
7214 * dispextern.h (hourglass_started):
7215 * w32fns.c (hourglass_started):
7216 * xdisp.c (hourglass_started): Remove.
7218 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7220 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7221 Update dependencies.
7223 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7225 * xgselect.c (xg_select): Put maxfds+1 into a var.
7226 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
7228 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7230 2012-05-10 Dave Abrahams <dave@boostpro.com>
7232 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7233 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7235 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7237 * dbusbind.c (xd_registered_buses): New internal Lisp object.
7238 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7239 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7240 Initialize xd_registered_buses.
7242 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7244 Untag more efficiently if USE_LSB_TAG.
7245 This is based on a proposal by YAMAMOTO Mitsuharu in
7246 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7247 For an admittedly artificial (nth 8000 longlist) benchmark on
7248 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7249 Emacs's overall text size by 1%.
7250 * lisp.h (XUNTAG): New macro.
7251 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7252 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7253 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7254 * eval.c (Fautoload):
7255 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7256 * frame.h (XFRAME): Use XUNTAG.
7258 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7259 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7260 Remove unportable assumptions about print widths of types like
7262 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7263 intptr_t when converting between pointer and integer, to avoid GCC
7264 warnings about wrong width.
7266 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7268 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7269 stack for each reader_thread, instead of defaulting to 8MB
7270 determined by the linker. This avoids failures in creating
7271 subprocesses on Windows 7, see the discussion in this thread:
7272 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7274 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7276 Fix up display of the *Minibuf-0* buffer in the mini window.
7277 * keyboard.c (read_char): Don't clear the echo area if there's no
7279 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7280 contents of *Minibuf-0*) if there's no message displayed in its stead.
7282 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7284 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7287 2012-05-06 Chong Yidong <cyd@gnu.org>
7289 * lisp.mk (lisp): Update.
7291 2012-05-05 Jim Meyering <meyering@redhat.com>
7293 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7295 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7297 * data.c (PUT_ERROR): New macro.
7298 (syms_of_data): Use it. Add new error type `user-error'.
7299 * undo.c (user_error): New function.
7300 (Fprimitive_undo): Use it.
7301 * print.c (print_error_message): Adjust print style for `user-error'.
7302 * keyboard.c (user_error): New function.
7303 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7305 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7307 Do not limit current-time-string to years 1000..9999.
7308 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7309 (Fcurrent_time_string): Support any year that is supported by the
7310 underlying localtime representation. Don't use asctime, as it
7311 has undefined behavior for years outside the range -999..9999.
7313 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7315 Fix race conditions involving setenv, gmtime, localtime, asctime.
7316 Without this fix, interrupts could mess up code that uses these
7317 nonreentrant functions, since setting TZ invalidates existing
7318 tm_zone or tzname values, and since most of these functions return
7319 pointers to static storage.
7320 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7321 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7322 Grow the critical sections to include not just invoking
7323 localtime/gmtime, but also accessing these functions' results
7324 including their tm_zone values if any, and any related TZ setting.
7325 (format_time_string): Last arg is now struct tm *, not struct tm **,
7326 so that the struct tm is saved in the critical section.
7327 All callers changed. Simplify allocation of initial buffer, partly
7328 motivated by the fact that memory allocation needs to be outside
7329 the critical section.
7331 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7333 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7334 with RESET_INTERVAL.
7336 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7337 Remove duplicated buffer name initialization.
7339 2012-05-02 Jim Meyering <jim@meyering.net>
7341 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7343 * xfns.c (x_window): Use xstrdup (Bug#11375).
7345 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7347 * xdisp.c (pos_visible_p): If already at a newline from the
7348 display string before the 'while' loop, don't walk back the glyphs
7349 from it3.glyph_row. Solves assertion violation when the display
7350 string begins with a newline (egg.el). (Bug#11367)
7352 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7354 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7357 2012-05-01 Glenn Morris <rgm@gnu.org>
7359 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7360 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7361 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7362 All were removed before 23.1.
7364 * dispnew.c: Remove HAVE_LIBNCURSES test;
7365 it is always true on relevant platforms.
7367 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7368 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7370 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
7372 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
7374 * .gdbinit (xpr): Remove checks for no longer existing misc types.
7375 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
7378 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
7380 Do not avoid creating empty evaporating overlays (Bug#9642).
7381 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7382 That is, do not delete an evaporating overlay if it becomes
7383 empty after its bounds are adjusted to fit within its buffer.
7384 This fix caused other problems, and I'm reverting it until we get
7385 to the bottom of them.
7387 2012-04-27 Chong Yidong <cyd@gnu.org>
7389 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7391 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7393 * xdisp.c (pos_visible_p): If the window start position is beyond
7394 ZV, start the display from buffer beginning. Prevents assertion
7395 violation in init_iterator when the minibuffer window is scrolled
7398 * window.c (window_scroll_pixel_based): Likewise.
7400 2012-04-27 Chong Yidong <cyd@gnu.org>
7402 * keymap.c (where_is_internal): Doc fix (Bug#10872).
7404 2012-04-27 Glenn Morris <rgm@gnu.org>
7406 * fileio.c (Fcopy_file, Fset_file_selinux_context):
7407 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
7409 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7411 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
7412 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
7414 2012-04-26 Eli Zaretskii <eliz@gnu.org>
7416 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7417 display element, check also the underlying string or buffer
7418 character. (Bug#11341)
7420 * w32menu.c: Include w32heap.h.
7421 (add_menu_item): If the call to AppendMenuW (via
7422 unicode_append_menu) fails, disable Unicode menus only if we are
7423 running on Windows 9X/Me.
7425 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7427 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
7428 (xgetint): Add missing shift for LSB tags.
7430 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7432 * keyboard.c (read_char): Don't wipe echo area for select window
7433 events: These might get delayed via `mouse-autoselect-window'
7436 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
7438 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
7439 manipulation of :loaded-from data.
7441 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
7443 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
7444 now a cons (bug#11311).
7446 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7448 Do not create empty overlays with the evaporate property (Bug#9642).
7449 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7450 if it becomes empty after its bounds are adjusted to fit within
7451 its buffer. Without this fix, in a nonempty buffer (let ((o
7452 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7453 yields an empty overlay that has the evaporate property, which is
7454 not supposed to happen.
7456 Fix minor GTK3 problems found by static checking.
7457 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7458 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7459 (struct _EmacsFixedClass, emacs_fixed_get_type):
7460 Move decls here from emacsgtkfixed.h, since they needn't be public.
7461 (emacs_fixed_get_type): Now static.
7462 (emacs_fixed_class_init): Omit unused local.
7463 (emacs_fixed_child_type): Remove; unused.

7465 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7466 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
7467 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
7468 (EMACS_FIXED_GET_CLASS): Remove; unused.
7469 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
7471 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
7472 Problem reported by Juanma Barranquero for Windows -Wunused-function.
7474 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7476 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
7477 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
7478 (__malloc_size_t, __malloc_ptrdiff_t):
7479 Remove. All uses removed, replaced by the definiens if needed,
7480 since we can assume C89 or better now.
7481 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
7482 (protect_malloc_state, align, get_contiguous_space)
7483 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
7484 (malloc_atfork_handler_child, malloc_enable_thread)

7489 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
7490 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
7491 Define using prototypes, not old style.
7492 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
7493 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
7494 (align): Don't assume that signed integer overflow wraps around.
7495 Omit unused local var.
7496 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
7497 (_free_internal_nolock, memalign, mallochook, reallochook):
7498 Omit no-longer-needed casts.
7499 (valloc): Use getpagesize, not __getpagesize.
7500 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
7501 (struct hdr): The 'magic' member is now size_t, not unsigned long.
7503 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
7505 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
7507 Move functions from C to Lisp. Make non-blocking method calls
7508 the default. Implement further D-Bus standard interfaces.
7510 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

7553 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
7554 Do not assume ptrdiff_t is the same width as 'int'.
7556 * alloc.c: Handle unusual debugging option combinations.
7557 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
7558 since the two debugging options are incompatible.
7559 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7561 (mem_init, mem_insert, mem_insert_fixup):
7562 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

7592 * print.c (print_preprocess): Only check print_depth if print-circle
7594 (print_object): Check for cycles even when print-circle is nil and
7595 print-gensym is t, but only check print_depth if print-circle is nil.
7597 2012-04-20 Chong Yidong <cyd@gnu.org>
7599 * process.c (wait_reading_process_output): If EIO occurs on a pty,

7615 farther than the first row after the header line, if any.
7616 Don't consider the header-line row as "partially visible", even if

7654 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
7655 New extern decls, to avoid calling undeclared functions.
7656 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
7657 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
7658 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

7660 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
7661 Remove one incorrect comment and fix another.

7699 Remove definition of GC_MARK_STACK, since the default now works.
7700 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
7701 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
7702 no longer the default.
7703 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
7705 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
7707 * lread.c (lisp_file_lexically_bound_p):

7728 2012-04-11 Daniel Colascione <dancol@dancol.org>
7730 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
7731 against is gone. It's better to use vfork now so that when Cygwin
7732 gains a new, working vfork, we use it automatically (bug#10398).
7734 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

7755 being loaded (bug#10424).
7757 2012-04-09 Glenn Morris <rgm@gnu.org>
7759 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
7760 not just in the obarray, before snarfing them. (Bug#11036)

7787 * minibuf.c (Fread_variable): Callers changed.
7789 2012-04-09 Eli Zaretskii <eliz@gnu.org>
7791 * xdisp.c (set_cursor_from_row): If the display string appears in
7792 the buffer at position that is closer to point than the position
7793 after the display string, display the cursor on the first glyph of
7794 the display string. Fixes cursor display when a 'display' text
7795 property immediately follows invisible text. (Bug#11094)
7797 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
7799 composite.c: use 'double' consistently
7800 * composite.c (get_composition_id): Use 'double' consistently
7801 instead of converting 'float' to 'double' and vice versa; this is
7802 easier to understand and avoids a GCC warning.
7804 2012-04-09 Glenn Morris <rgm@gnu.org>
7806 * Makefile.in: Generate leim-list with bootstrap-emacs, in
7807 preparation for dumping it with emacs. (Bug#4789)

7829 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
7830 (mark_memory): Mark Lisp_Objects only if pointers might hide in

7849 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
7850 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
7851 [!WINDOWSNT]: New macros.
7852 (init_libxml2_functions, libxml2_loaded_p): New functions.
7853 (parse_region): Call fn_xmlCheckVersion instead of using the macro
7854 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
7855 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
7856 Calls xmlCleanupParser only if libxml2 was loaded (or statically
7858 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
7859 Call init_libxml2_functions before calling libxml2 functions.
7860 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
7862 * emacs.c: Don't include libxml/parser.h.

7864 xmlCleanupParser directly.
7866 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
7868 2012-04-07 Eli Zaretskii <eliz@gnu.org>

7876 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
7877 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
7878 about subtle differences between FETCH_CHAR* and STRING_CHAR*
7879 macros related to unification of CJK characters. For the details,
7880 see the discussion following the message here:
7881 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
7883 2012-04-04 Chong Yidong <cyd@gnu.org>
7885 * keyboard.c (Vdelayed_warnings_list): Doc fix.
7887 2012-04-01 Eli Zaretskii <eliz@gnu.org>
7889 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

7897 2012-03-31 Eli Zaretskii <eliz@gnu.org>
7899 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
7900 position we get to after a call to move_it_to fails the
7901 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
7902 only if we wind up in a string from display property. (Bug#11063)
7904 * window.c (Fdelete_other_windows_internal): Invalidate the row
7905 and column information about mouse highlight, so that redisplay
7906 restores it after reallocating the glyph matrices. (Bug#7464)
7908 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
7909 string comes from a `display' text property, use the buffer
7910 position of that property as if we actually saw that position in
7912 (move_it_by_lines): Remove the assertion that
7913 "it->current_x == 0 && it->hpos == 0" which can be legitimately
7914 violated when there's a before-string at the beginning of a line.
7917 2012-03-30 Eli Zaretskii <eliz@gnu.org>
7919 * xdisp.c (append_space_for_newline): If the default face was
7920 remapped, use the remapped face for the appended newline.
7921 (extend_face_to_end_of_line): Use the remapped default face for
7922 extending the face to the end of the line.
7923 (display_line): Call extend_face_to_end_of_line when the default
7924 face was remapped. (Bug#11068)
7926 2012-03-29 Eli Zaretskii <eliz@gnu.org>
7928 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

7948 handle-select-window too (Bug#8996).
7950 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
7952 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.

7956 * dispextern.h (struct glyph): Change the bit length of
7957 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
7959 2012-03-24 Eli Zaretskii <eliz@gnu.org>
7961 * s/ms-w32.h (tzname): Include time.h before redirecting to
7962 _tzname. Fixes the MSVC build. (Bug#9960)
7964 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
7966 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
7969 * xterm.c (XTread_socket): Only modify handling_signal if
7970 !SYNC_INPUT. (Bug#11080)
7972 2012-03-23 Eli Zaretskii <eliz@gnu.org>
7974 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
7975 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
7976 when fetching a multibyte character consumes more bytes than
7977 CHAR_BYTES returns, due to unification of CJK characters in
7978 string_char. (Bug#11073)

8004 2012-03-20 Chong Yidong <cyd@gnu.org>
8006 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
8007 to reflect default non-nil value of redisplay-dont-pause.
8009 2012-03-19 Kenichi Handa <handa@m17n.org>
8011 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
8012 it fit in a valid range (Bug#11003).
8014 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8016 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8017 that is not from display property, accept the row as a "cursor
8018 row" if one of the string's character has a non-nil `cursor'
8019 property. Fixes cursor positioning when there are newlines in
8020 overlay strings, e.g. in icomplete.el. (Bug#11035)
8022 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

8053 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8056 2012-03-03 Glenn Morris <rgm@gnu.org>
8058 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

8076 push_it before setting up the iterator for the first overlay
8077 string, even if we have an empty string loaded.
8078 (next_overlay_string): If there's an empty string on the iterator
8079 stack, pop the stack. (Bug#10903)
8081 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8083 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8084 Suggested by Stefan Monnier in
8085 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8086 * alloc.c (widen_to_Lisp_Object): New static function.
8087 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8088 and widening them to Lisp_Objects. This would work even if
8089 USE_LSB_TAG is defined and wide integers are used, which might
8090 happen in a future version of Emacs.
8092 2012-02-25 Chong Yidong <cyd@gnu.org>
8094 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

8108 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
8109 call when setting menu-bar-lines and tool-bar-lines parameters.
8110 (unwind_create_frame_1): New helper function.
8112 * window.c (inhibit_window_configuration_change_hook): New var.
8113 (run_window_configuration_change_hook): Obey it.
8114 (syms_of_window): Initialize it.
8116 2012-02-22 Chong Yidong <cyd@gnu.org>
8118 * xterm.c (x_draw_image_relief): Add missing type check for

8130 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
8131 when computing $valmask.
8133 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8134 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8135 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8136 It's useless in that case, and it can cause problems on hosts
8137 that allocate halves of EMACS_INT values separately.
8138 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8139 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8140 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8141 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8142 it avoids undefined behavior on hosts where shifting right by more
8143 than the word width has undefined behavior.
8145 2012-02-19 Chong Yidong <cyd@gnu.org>
8147 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
8148 (Funhandled_file_name_directory, Ffile_name_as_directory)
8149 (Fdirectory_file_name, Fexpand_file_name)

8167 2012-02-15 Chong Yidong <cyd@gnu.org>
8169 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
8170 marked as special. Also, starting docstrings with * is obsolete.
8172 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>

8185 2012-02-12 Chong Yidong <cyd@gnu.org>
8187 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
8188 as that creates a dangerous corner case.
8190 * window.c (Fdelete_window_internal): Invalidate the mouse
8191 highlight (Bug#9904).
8193 2012-02-12 Glenn Morris <rgm@gnu.org>

8199 (Fx_disown_selection_internal, Fx_selection_exists_p)
8200 (Fx_selection_owner_p, Fx_get_selection_internal):
8201 Sync docs and argument specs with the xselect.c versions.

8223 2012-02-07 Chong Yidong <cyd@gnu.org>
8225 * buffer.c (Fbuffer_local_variables)
8226 (buffer_lisp_local_variables): Handle unbound vars correctly;
8227 don't let Qunbound leak into Lisp.
8229 2012-02-07 Glenn Morris <rgm@gnu.org>
8231 * image.c (Fimagemagick_types): Doc fix.
8233 * image.c (imagemagick-render-type): Change it from a lisp object

8239 * doc.c (store_function_docstring): Avoid applying docstring of
8240 alias to base function (Bug#2603).
8242 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
8244 * .gdbinit (pp1, pv1): Remove redundant defines.

8266 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
8268 Handle overflow when computing char display width (Bug#9496).
8269 * character.c (char_width): Return EMACS_INT, not int.
8270 (char_width, c_string_width): Check for overflow when
8271 computing the width; this is possible now that individual
8272 characters can have unbounded width. Problem introduced
8273 by merge from Emacs 23 on 2012-01-19.
8275 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

8304 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
8305 first 2 arguments are identical. This makes inserting large
8306 output from a subprocess an order of magnitude faster on
8307 MS-Windows, where all sbrk'ed memory is always contiguous.

8407 DISP_STRING, and accept any glyph in a row whose object is that
8408 string as eligible for mouse highlight. Fixes mouse highlight of
8409 display strings from overlays. (Bug#10464)
8411 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
8413 emacs: fix an auto-save permissions race condition (Bug#10400)
8414 * fileio.c (auto_saving_dir_umask): New static var.
8415 (Fmake_directory_internal): Use it.
8416 (do_auto_save_make_dir): Set it, instead of invoking chmod after
8417 creating the directory. The old code temporarily assigns
8418 too-generous permissions to the directory.
8419 (do_auto_save_eh): Clear it.
8420 (Fdo_auto_save): Catch all errors, not just file errors, so
8421 that the var is always cleared.

8425 * search.c (scan_buffer): Pass character positions to
8426 know_region_cache, not byte positions. (Bug#6540)

8476 2011-12-23 Eli Zaretskii <eliz@gnu.org>
8478 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
8479 property that ends at ZV, so that the bidi iteration could be

8927 is set, removing the need for VIRT_ADDRESS_VARIES.
8928 (PURE_P): Use a more-efficient implementation that needs just one

8944 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
8945 behave as if the cursor position were at the window margin.
8947 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
8948 and the cursor position is out of bounds, behave as if the cursor
8949 position were at the window margin. (Bug#10075)

9444 (Fgnutls_deinit, Fgnutls_boot): Use it.
9446 * process.c (make_process): Initialize GnuTLS credentials to NULL.
9447 (deactivate_process): Call emacs_gnutls_deinit.
9449 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9451 * image.c (x_create_x_image_and_pixmap):
9452 * w32.c (sys_rename, w32_delayed_load):
9453 * w32font.c (fill_in_logfont):
9454 * w32reg.c (x_get_string_resource): Silence compiler warnings.
9456 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
9458 * w32fns.c (w32_default_color_map): New function,
9459 extracted from Fw32_default_color_map.
9460 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
9462 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
9464 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
9466 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
9468 * keyboard.c (test_undefined): New function (bug#9751).
9469 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
9471 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
9473 * sysdep.c (init_sys_modes): Fix the check for the controlling
9474 terminal (Bug#6649).
9476 2011-10-20 Eli Zaretskii <eliz@gnu.org>
9478 * dispextern.h (struct bidi_it): New member next_en_type.
9480 * bidi.c (bidi_line_init): Initialize the next_en_type member.
9481 (bidi_resolve_explicit_1): When next_en_pos is valid for the
9482 current character, check also for next_en_type being WEAK_EN.
9483 (bidi_resolve_weak): Don't enter the expensive loop if the current
9484 position is before next_en_pos. Record the bidi type of the first
9485 non-ET, non-BN character we find, in addition to its position.
9486 (bidi_level_of_next_char): Invalidate next_en_type when
9487 next_en_pos is over-stepped.
9489 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
9491 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
9492 * editfns.c: Rewrite current-time-zone so that it invokes
9493 the equivalent of (format-time-string "%Z") to get the time zone name.
9494 This fixes a bug when the time zone name contains characters that
9495 need converting from the system time locale to Emacs internal format.
9496 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9497 that patch fixed format-time-string to do the conversion, but
9498 I forgot to fix current-time-zone.
9499 (format_time_string): New function, containing most of
9500 what Fformat_time_string used to contain.
9501 (Fformat_time_string): Rewrite in terms of format_time_string.
9502 This doesn't change this function's behavior.
9503 (current-time-zone): Rewrite to use format_time_string.
9504 This fixes the bug reported by Michael Schierl in
9505 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9506 Jason Rumney's 2007-06-07 change worked around this bug, but
9508 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9510 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9512 * xdisp.c (start_display): If the character at POS is displayed
9513 via a display vector, reset IT->current.dpvec_index to zero.
9514 (try_window_reusing_current_matrix): If a line ends in a display
9515 vector or the next line starts in a display vector, continue
9516 redrawing the window even though the character position of
9517 start_row was reached.
9520 2011-10-18 Chong Yidong <cyd@gnu.org>
9522 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9523 with nobreak-char-display too.
9525 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9527 Fix part 3 of bug#9771.
9528 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9529 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9530 non-neutral characters if the current character is a paragraph
9531 separator (a.k.a. Newline). This avoids running the same
9532 expensive loop twice, once when we consume the preceding newline
9533 and the other time when the line actually needs to be displayed.
9534 Avoid the loop when we see neutrals on the base embedding level
9535 following a character whose directionality is the same as the
9536 paragraph's. This avoids running the expensive loop when a line
9537 ends in a long sequence of neutrals, like control characters.
9538 Add assertion against STRONG_AL type. Slightly rearrange code
9539 that determines the type of a neutral given the first non-neutral
9541 (bidi_level_of_next_char): Set next_en_pos to zero when
9542 invalidating its info.
9544 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9546 * xdisp.c (push_display_prop): Determine whether to record string
9547 or buffer position by IT->string, not by IT->method. Allow
9548 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9549 (move_it_vertically_backward): Don't look for character position
9550 immediately after the newline when in a continuation line.
9553 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9555 * window.c (coordinates_in_window): Rewrite and delabelize
9556 vertical border check. (Bug#5357) (Bug#9618)
9558 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9560 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9561 errors in XSetWindowBorder (bug#9310).
9563 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9565 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9566 avoid crash when xmalloc overrun checking is enabled.
9568 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9570 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9571 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9572 cursor motion with <left> and <right> arrow keys.
9574 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9575 some callers set that themselves.
9577 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9579 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9580 display string and the previous row comes from the same string and
9581 is empty. (Bug#9739) (Bug#9738)
9583 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9585 * doc.c (get_doc_string): Encode file name (bug#9735).
9587 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9589 * bidi.c (bidi_level_of_next_char):
9590 * xdisp.c (get_visually_first_element): Remove old incorrect
9591 comments regarding the Unicode Line Separator character.
9593 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9595 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9597 * alloc.c (Fgc_status): Do not access beyond zombies array
9598 boundary if nzombies > MAX_ZOMBIES.
9599 * alloc.c (dump_zombies): Add missing format specifier.
9601 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9603 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9604 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9606 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9607 Some packages use them to denote characters with modifiers.
9609 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9611 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9612 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9613 matching a pp-number. Rename parameter var to var1.
9615 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9617 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9619 2011-10-08 Glenn Morris <rgm@gnu.org>
9621 * callint.c (Fcall_interactively): Give a more explicit error for the
9622 'c' case with a non-character input. (Bug#8479)
9624 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9626 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9628 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9629 lines that are hscrolled on the left.
9631 * dispnew.c (buffer_posn_from_coords): Account for a possible
9632 presence of header-line. (Bug#4426)
9634 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
9636 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
9637 Don't advertise functionality which we discourage or doesn't work.
9639 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
9641 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
9642 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
9643 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
9644 this makes Emacs dump core during garbage collection on rare
9645 occasions. sizeof is obviously inferior to offsetof here, so
9646 stick with offsetof.
9647 (GC_POINTER_ALIGNMENT): New macro.
9648 (mark_memory): Omit 3rd (offset) arg; caller changed.
9649 Don't assume EMACS_INT alignment is the same as pointer alignment.
9651 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
9653 * keyboard.c (read_key_sequence_remapped): New var.
9654 (read_key_sequence): Compute remapping in the right buffer.
9655 (command_loop_1): Use read_key_sequence's remapping directly.
9657 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
9659 * dired.c (file_name_completion): Don't expand file name.
9660 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
9661 before checking file name handler.
9663 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
9664 they've been requested explicitly (bug#9591).
9666 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
9668 * keymap.c (Fsingle_key_description): Use make_specified_string
9669 instead of build_string to build string from push_key_description.
9672 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9674 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
9675 This fixes a Y2038 bug on 64-bit hosts.
9676 * buffer.c (reset_buffer):
9677 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
9678 (Fclear_buffer_auto_save_failure):
9679 Use 0, not -1, to represent an unset failure time, since time_t
9680 might not be signed.
9682 Remove dependency on glibc malloc internals.
9683 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9684 Move back here from lisp.h, but with their new implementations.
9685 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9686 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
9687 * charset.c (charset_table_init): New static var.
9688 (syms_of_charset): Use it instead of xmalloc. This removes a
9689 dependency on glibc malloc internals. See Eli Zaretskii's comment in
9690 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
9691 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9692 Move back to alloc.c.
9693 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9694 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
9696 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
9698 * nsterm.m (windowDidResize): Call x_set_window_size only when
9699 ns_in_resize is true. Otherwise set pixelwidth/height and
9700 call change_frame_size (Bug#9628).
9702 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9704 Port --enable-checking=all to Fedora 14 x86-64.
9705 * charset.c (syms_of_charset): Also account for glibc malloc's
9706 internal overhead when calculating the initial malloc maximum.
9708 Port --enable-checking=all to Fedora 14 x86.
9709 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9711 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
9712 (overrun_check_realloc, overrun_check_free):
9713 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
9714 That way, xmalloc returns a properly-aligned pointer even if
9715 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
9716 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
9717 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
9718 into account when calculating the initial malloc maximum.
9719 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9720 Move here from alloc.c, so that charset.c can use it too.
9721 Properly align; the old code wasn't right for common 32-bit hosts
9722 when configured with --enable-checking=all.
9723 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9724 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
9726 2011-09-29 Eli Zaretskii <eliz@gnu.org>
9728 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
9731 2011-09-28 Eli Zaretskii <eliz@gnu.org>
9733 * xdisp.c (compute_display_string_end): If there's no display
9734 string at CHARPOS, return -1.
9736 * bidi.c (bidi_fetch_char): When compute_display_string_end
9737 returns a negative value, treat the character as a normal
9738 character not covered by a display string. (Bug#9624)
9740 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
9742 * lread.c (Fread_from_string): Fix typo in docstring.
9744 2011-09-27 Eli Zaretskii <eliz@gnu.org>
9746 * xdisp.c (handle_invisible_prop): If invisible text ends on a
9747 newline, reseat the iterator instead of bidi-iterating there one
9748 character at a time. (Bug#9610)
9749 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
9750 TO_CHARPOS if the bidi iterator is at base embedding level.
9752 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
9754 * lread.c (readevalloop): Use correct code for NBSP.
9755 (read1): Likewise. (Bug#9608)
9757 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
9759 * dbusbind.c (Fdbus_register_signal): When service is not
9760 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
9762 2011-09-25 Glenn Morris <rgm@gnu.org>
9764 * buffer.c (truncate-lines): Doc fix.
9766 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
9768 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
9769 (Fset_window_next_buffers): Doc fix.
9771 2011-09-24 Glenn Morris <rgm@gnu.org>
9773 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
9775 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
9777 Fix minor problems found by static checking.
9778 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
9779 * indent.c (Fvertical_motion): Fix == vs = typo.
9781 2011-09-24 Eli Zaretskii <eliz@gnu.org>
9783 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
9784 Default value is now t. Doc fix.
9786 * indent.c (Fvertical_motion): Compute and apply the overshoot
9787 logic when moving up, not only when moving down. Fix the
9788 confusing name and values of the it_overshoot_expected variable;
9789 logic changes accordingly. (Bug#9254) (Bug#9549)
9791 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
9792 CHARPOS is covered by a display string which includes newlines.
9793 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
9794 is covered by a display string with embedded newlines.
9796 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
9798 * dbusbind.c (Fdbus_register_signal): Add match rule to
9799 Vdbus_registered_objects_table. (Bug#9581)
9800 (Fdbus_register_method, Vdbus_registered_objects_table):
9803 2011-09-24 Jim Meyering <meyering@redhat.com>
9805 do not ignore write error for any output size
9806 The previous change was incomplete.
9807 While it makes emacs --batch detect the vast majority of stdout
9808 write failures, errors were still ignored whenever the output size is
9809 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
9810 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
9811 && echo FAIL: ignored write error
9812 FAIL: ignored write error
9813 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
9814 && echo FAIL: ignored write error
9815 FAIL: ignored write error
9816 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
9818 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
9820 * emacs.c (Fkill_emacs): In noninteractive mode exit
9821 non-successfully if a write error occurred on stdout. (Bug#9574)
9823 2011-09-21 Eli Zaretskii <eliz@gnu.org>
9825 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
9828 * dispextern.h (struct it): Update the comment documenting what
9831 2011-09-20 Eli Zaretskii <eliz@gnu.org>
9833 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
9834 a display string, extend search for cursor position to end of row.
9835 (find_row_edges): If the row ends in a newline from a display
9836 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
9837 Handle the case of a display string with multiple newlines.
9838 (Fcurrent_bidi_paragraph_direction): Fix search for previous
9839 non-empty line. Fixes confusing cursor motion with arrow keys at
9840 the beginning of a line that starts with whitespace.
9842 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9844 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
9847 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
9849 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
9852 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9854 * xdisp.c (display_line): Record maximum and minimum buffer
9855 positions even if no glyphs were produced (e.g., by a zero-width
9856 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
9857 buffer positions that will be removed from the glyph row because
9859 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
9860 column is beyond frame width: don't subtract 1 "pixel" when
9861 computing width of the stretch.
9862 (reseat_at_next_visible_line_start): Undo the change made on
9863 2011-09-17 that saved paragraph information and restored it after
9864 the call to `reseat'. (Bug#9545)
9866 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9868 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
9869 and turn window cursor on if cleared (Bug#9415).
9871 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
9873 * search.c (boyer_moore): Take unibyte characters from pattern
9874 literally. (Bug#9458)
9876 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9878 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
9880 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
9882 Fix minor problem found by static checking.
9883 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
9884 initialized, to pacify gcc -Wuninitialized.
9886 * fileio.c: Report proper errno when syscall falls.
9887 (Finsert_file_contents): Save and restore errno,
9888 so that report_file_error outputs the correct diagnostic.
9889 (Fwrite_region) [CLASH_DETECTION]: Likewise.
9891 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9893 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
9895 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9897 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
9898 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
9900 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9902 * xdisp.c (reseat_at_next_visible_line_start): Keep information
9903 about the current paragraph and restore it after the call to reseat.
9905 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
9906 (bidi_find_paragraph_start): Search back for paragraph beginning
9907 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
9908 (bidi_move_to_visually_next): Only trigger paragraph-related
9909 computations when the last character is a newline or at EOB, not
9910 just any NEUTRAL_B. (Bug#9470)
9912 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
9913 truncated lines if point is covered by a display string. (Bug#9524)
9915 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
9917 * xselect.c: Relax test for outgoing X longs (Bug#9498).
9918 (cons_to_x_long): New function.
9919 (lisp_data_to_selection_data): Use it. Correct the test for
9920 short-versus-long data; it was negated. Break out of vector
9921 loop, for efficiency, when a long datum is discovered.
9923 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
9925 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
9927 2011-09-16 Eli Zaretskii <eliz@gnu.org>
9929 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
9930 GCC PR/17406) by declaring this function with external scope.
9932 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9934 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
9935 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
9937 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
9939 * editfns.c (Fformat): Correctly handle text properties on "%%".
9941 2011-09-15 Eli Zaretskii <eliz@gnu.org>
9943 * xterm.c (x_draw_composite_glyph_string_foreground):
9944 * w32term.c (x_draw_composite_glyph_string_foreground):
9945 * term.c (encode_terminal_code):
9946 * composite.c (composition_update_it, get_composition_id):
9947 * xdisp.c (get_next_display_element)
9948 (fill_composite_glyph_string): Add comments about special meaning
9949 of TAB characters in a composition.
9951 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9953 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
9954 This occurs when processing a multibyte format.
9955 Problem reported by Wolfgang Jenker.
9957 2011-09-15 Johan Bockgård <bojohan@gnu.org>
9959 * xdisp.c (try_cursor_movement): Only check for exact match if
9960 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
9962 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9964 Remove unused external symbols.
9965 * dispextern.h (calc_pixel_width_or_height): Remove decl.
9966 * xdisp.c (calc_pixel_width_or_height): Now static.
9967 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
9968 * indent.c (check_display_width):
9969 * w32term.c: Fix comment to match code.
9970 * xterm.c, xterm.h (x_catching_errors): Remove.
9972 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9974 * xselect.c: Use signed conversions more consistently (Bug#9498).
9975 (selection_data_to_lisp_data): Assume incoming selection data are
9976 signed integers, not unsigned. This is to be consistent with
9977 outgoing selection data, which was modified to use signed integers
9978 in as part of the fix to Bug#9196 in response to Jan D.'s comment
9979 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
9980 expects long, not unsigned long.
9982 2011-09-14 Eli Zaretskii <eliz@gnu.org>
9984 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
9985 computation of loop end. Reported by Johan Bockgård
9988 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
9990 * frame.c (Fother_visible_frames_p): Function deleted.
9992 2011-09-12 Eli Zaretskii <eliz@gnu.org>
9994 * indent.c (compute_motion): Process display vector front to back
9995 rather than the other way around. (Bug#2496)
9997 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
9999 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
10001 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
10003 * minibuf.c (Fread_from_minibuffer): Doc fix.
10005 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10007 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
10008 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
10010 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
10012 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
10013 value for non-existent files.
10015 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10017 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10018 set its "size" to -1. This will set the modtime_size field of
10019 the corresponding buffer to -1, which is what
10020 verify-visited-file-modtime expects for files that do not exist.
10023 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
10025 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10027 * lisp.h: ... from here. push_key_description is no longer
10028 defined in keyboard.c, so its declaration should not be in
10029 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10030 logically belongs with push_key_description.
10032 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10034 * buffer.h: Include <sys/types.h> instead of <time.h>.
10035 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
10036 Problem reported by Herbert J. Skuhra.
10038 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
10040 * xml.c (parse_region): Make the parsing work for
10041 non-comment-starting XML files again (bug#9144).
10043 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
10045 * image.c (gif_load): Fix calculation of bottom and right corner.
10048 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10050 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10051 redisplay in small windows.
10053 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10055 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10057 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10059 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10060 Operate on live windows only.
10062 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10064 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10066 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10068 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10069 only under bidi iteration.
10071 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10073 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10075 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10077 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10078 Without this fix, the command to link temacs failed due to an
10079 undefined symbol __builtin_isnan. This is because
10080 /usr/include/iso/math_c99.h #defines isnan(x) to
10081 __builtin_isnan(x), but the bundled gcc, which identifies itself
10082 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10084 * floatfns.c (isnan): #undef, and then #define to a clone of
10086 (Fisnan): Always define, since it's always available now.
10087 (syms_of_floatfns): Always define isnan at the Lisp level.
10089 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10091 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10093 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10095 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10096 The previous code assumed that file offsets (off_t values) fit in
10097 EMACS_INT variables, which is not true on typical 32-bit hosts.
10098 The code messed up by falsely reporting buffer overflow in cases
10099 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10100 when "big" contains more than 2**29 bytes, even though this
10101 inserts just one byte and does not overflow the buffer.
10102 (Finsert_file_contents): Store file offsets as off_t
10103 values, not as EMACS_INT values. Check for overflow when
10104 converting between EMACS_INT and off_t. When checking for
10105 buffer overflow or for overlap, take the offsets into account.
10106 Don't use EMACS_INT for small values where int suffices.
10107 When checking for overlap, fix a typo: ZV was used where
10108 ZV_BYTE was intended.
10109 (Fwrite_region): Don't assume off_t fits into 'long'.
10110 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10112 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10114 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10116 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10118 sprintf-related integer and memory overflow issues (Bug#9412).
10120 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10121 (esprintf, exprintf, evxprintf): New functions.
10122 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10123 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10124 (modify_event_symbol): Do not assume that the length of
10125 name_alist_or_stem is safe to alloca and fits in int.
10126 (Fexecute_extended_command): Likewise for function name and binding.
10127 (Frecursion_depth): Wrap around reliably on integer overflow.
10128 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10129 since some callers pass EMACS_INT values.
10130 (Fsingle_key_description): Don't crash if symbol name contains more
10131 than MAX_ALLOCA bytes.
10132 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10133 (get_minibuffer): Arg is now EMACS_INT, not int.
10134 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10135 (esprintf, exprintf, evxprintf): New decls.
10136 * window.h (command_loop_level, minibuf_level): Reflect API changes.
10138 * dbusbind.c (signature_cat): New function.
10139 (xd_signature, Fdbus_register_signal):
10140 Do not overrun buffer; instead, report string overflow.
10142 * dispnew.c (add_window_display_history): Don't overrun buffer.
10143 Truncate instead; this is OK since it's just a log.
10145 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10146 even if the time zone offset is outlandishly large.
10147 Don't mishandle offset == INT_MIN.
10149 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10150 when creating daemon; the previous buffer-overflow check was incorrect.
10152 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10153 which has the guts of the old verror function.
10155 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10156 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10158 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10159 (font_unparse_xlfd): Don't blindly alloca long strings.
10160 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10161 fits in int, when using sprintf. Use single snprintf to count
10162 length of string rather than counting it via multiple sprintfs;
10163 that's simpler and more reliable.
10164 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10165 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10166 sprintf, in case result does not fit in int.
10168 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10169 (fontset_from_font): Print it.
10171 * frame.c (tty_frame_count): Now printmax_t, not int.
10172 (make_terminal_frame, set_term_frame_name): Print it.
10173 (x_report_frame_params): In X, window IDs are unsigned long,
10174 not signed long, so print them as unsigned.
10175 (validate_x_resource_name): Check for implausibly long names,
10176 and don't assume name length fits in 'int'.
10177 (x_get_resource_string): Don't blindly alloca invocation name;
10178 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10181 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10182 (xg_check_special_colors, xg_set_geometry):
10183 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10185 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10186 Use esprintf, not sprintf, in case result does not fit in int.
10188 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10189 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10190 it as a large positive number.
10191 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10192 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10194 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10195 in case result does not fit in int.
10197 * print.c (float_to_string): Detect width overflow more reliably.
10198 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10199 buffer overrun. Don't assume list length fits in 'int'. Treat
10200 print length of 0 as 0, not as infinity; to be consistent with other
10201 uses of print length in this function. Don't overflow print length
10202 index. Don't assume hash table size fits in 'long', or that
10203 vectorlike size fits in 'unsigned long'.
10205 * process.c (make_process): Use printmax_t, not int, to format
10206 process-name gensyms.
10208 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10210 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10211 to avoid potential buffer overrun.
10213 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10214 if X resource line is longer than 512 bytes.
10216 * xfns.c (x_window): Make sprintf buffer a bit bigger
10217 to avoid potential buffer overrun.
10219 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10221 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10223 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10225 Integer overflow fixes for scrolling, etc.
10226 Without these, Emacs silently mishandles large integers sometimes.
10227 For example, "C-u 4294967297 M-x recenter" was treated as if
10228 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10230 * xdisp.c (try_window_id): Check Emacs fixnum range before
10231 converting to 'int'.
10233 * window.c (window_scroll_line_based, Frecenter):
10234 Check that an Emacs fixnum is in range before assigning it to 'int'.
10235 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10236 values converted from Emacs fixnums.
10237 (Frecenter): Don't wrap around a line count if it is out of 'int'
10238 range; instead, treat it as an extreme value.
10239 (Fset_window_configuration, compare_window_configurations):
10240 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10242 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10243 that can exceed INT_MAX. Check that EMACS_INT value is in range
10244 before assigning it to the (possibly-narrower) index.
10245 (match_limit): Don't assume that a fixnum can fit in 'int'.
10247 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10250 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10251 (Fvertical_motion): Don't wrap around LINES values that don't fit
10252 in 'int'. Instead, treat them as extreme values. This is good
10253 enough for windows, which can't have more than INT_MAX lines anyway.
10255 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10257 * Require libxml/parser.h to avoid compilation warning.
10259 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10261 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10262 since this reportedly can destroy thread storage.
10264 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10266 * syntax.c (find_defun_start): Update all cache variables if
10267 exiting early (Bug#9401).
10269 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10271 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10273 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10274 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10275 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10277 * term.c (tty_append_glyph): New function.
10278 (produce_stretch_glyph): Static function and its prototype deleted.
10280 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10283 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10285 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10286 when checking :margin (Bug#9390).
10287 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10288 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10289 so that the name doesn't mislead. All uses changed.
10291 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10293 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
10296 2011-08-27 Eli Zaretskii <eliz@gnu.org>
10298 * xdisp.c (move_it_to): Don't bail out early when reaching
10299 position beyond to_charpos, if we are scanning backwards.
10300 (move_it_vertically_backward): When DY == 0, make sure we get to
10301 the first character in the line after the newline.
10303 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10305 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10306 (ccl_driver): Do not generate an out-of-range pointer.
10307 (Fccl_execute_on_string): Remove unnecessary check for
10308 integer overflow, noted by Stefan Monnier in
10309 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10310 Remove a FIXME that didn't need fixing.
10311 Simplify the newly-introduced buffer reallocation code.
10313 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10315 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10317 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10319 Integer and memory overflow issues (Bug#9196).
10321 * doc.c (get_doc_string): Rework so that
10322 get_doc_string_buffer_size is the actual buffer size, rather than
10323 being 1 less than the actual buffer size; this makes xpalloc more
10326 * image.c (x_allocate_bitmap_record, cache_image):
10327 * xselect.c (Fx_register_dnd_atom):
10328 Simplify previous changes by using xpalloc.
10330 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10331 since either will do and ptrdiff_t is convenient with xpalloc.
10333 * charset.c (charset_table_size)
10334 (struct charset_sort_data.priority): Now ptrdiff_t.
10335 (charset_compare): Don't overflow if priorities differ greatly.
10336 (Fsort_charsets): Don't assume list length fits in int.
10337 Check for size-calculation overflow when allocating sort data.
10338 (syms_of_charset): Allocate an initial charset table that is
10339 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10341 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10343 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10344 The actual value is always <= INT_MAX, and leaving it unsigned made
10345 overflow checking harder.
10347 * dispextern.h (struct glyph_matrix.rows_allocated)
10348 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10349 with xpalloc. The values are still always <= INT_MAX.
10351 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10353 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10354 (SAFE_NALLOCA): New macro.
10356 * region-cache.c (struct boundary.pos, find_cache_boundary)
10357 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10358 (set_cache_region, invalidate_region_cache)
10359 (revalidate_region_cache, know_region_cache, region_cache_forward)
10360 (region_cache_backward, pp_cache):
10361 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10362 so that ptrdiff_t * can be passed to xpalloc.
10363 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
10364 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
10365 (pp_cache): Don't assume cache_len fits in int.
10366 * region-cache.h: Adjust extern decls to match.
10368 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
10369 EMACS_INT, since either will do, for xpalloc.

10382 because xmalloc/xrealloc may not return.
10383 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10384 now that we have proper integer overflow checking.
10385 (record_overlay_string, overlay_strings): Catch overflows when
10386 calculating size of overlay_str_buf.
10388 * callproc.c (Fcall_process): Check for size overflow when
10389 calculating size of args2.
10390 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.

10392 require adding more-complicated checks.
10394 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10395 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

10435 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10437 * emacs.c (main): Do not reallocate argv, since there is a null at
10438 the end that can be overwritten, and this way there's no need to
10439 worry about size-calculation overflow.
10440 (sort_args): Check for size-calculation overflow.
10442 * eval.c (init_eval_once, grow_specpdl): Don't update size until

10448 Check for integer overflow.
10449 (x_set_alpha): Do not assume XINT fits in int.
10451 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10452 This is for the members text_lines, text_cols, total_lines, total_cols,
10453 where the system imposes an 'int' limit.
10455 * fringe.c (Fdefine_fringe_bitmap):
10456 Don't update size until alloc works.

10461 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
10462 Check for size-calculation overflow.
10463 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10464 do, as we prefer signed integers.
10465 (id_to_widget.max_size, id_to_widget.used)
10466 (xg_store_widget_in_map, xg_remove_widget_from_map)

10471 * gtkutil.h: Change prototypes to match the above.
10473 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

10520 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
10521 for command line length. Do not attempt to address one before the
10522 beginning of an array, as that's not portable.

10557 (Fx_change_window_property): Use ptrdiff_t, not int, to count
10558 sizes, since they can exceed INT_MAX in size. Check for size

10568 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
10569 (X_LONG_MIN): New macros.
10570 Use them to make the following changes clearer.
10571 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
10572 This change doesn't affect the value now, but it may help remind
10573 future maintainers not to raise the value too much later.
10574 (SELECTION_QUANTUM): Remove, replacing with ...
10575 (selection_quantum): ... new function, which avoids overflow.
10577 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10578 assumption that selection length fits in 'int'.

10595 Don't store size until memory allocation succeeds.
10596 (x_get_window_property): Plug memory leak on memory exhaustion.
10597 Don't double-block input; malloc is safe here. Don't assume 2**34
10598 - 4 fits in unsigned long. Add an xassert to check
10599 XGetWindowProperty overflow. Be more careful about overflow
10600 calculations, and distinguish size from memory overflow better.
10601 (receive_incremental_selection): When tracing, don't assume
10602 unsigned int is less than INT_MAX.
10603 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

10606 in the range -65535 through -1 fit in an X unsigned short.
10607 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10608 result parameters unless successful. Rely on cons_to_unsigned
10609 to report problems with elements; the old code wasn't right anyway.
10610 (x_check_property_data): Check for int overflow; we cannot use
10611 a wider type due to X limits.

10644 * lisp.h (hash_lookup, hash_put):
10645 * minibuf.c (Ftest_completion):
10646 Use ptrdiff_t for hash table indexes, not int (which is too
10647 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
10648 32-bit --with-wide-int hosts).
10650 * charset.c (Fdefine_charset_internal): Check for integer overflow.
10651 Add a FIXME comment about memory leaks.

10659 with outlandish widths.
10660 * character.h (sanitize_tab_width): Rename from sanitize_width,
10661 now that we have two such functions. All uses changed.

10680 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
10681 (x_send_scroll_bar_event): Likewise. Check that the size does not
10682 exceed limits imposed by XClientMessageEvent, as well as the usual
10683 ptrdiff_t and size_t limits.
10685 * keyboard.c: Overflow, signedness and related fixes.
10686 (make_lispy_movement): Use same integer type in forward decl
10687 that is used in the definition.
10688 (read_key_sequence, keyremap_step):
10689 Change bufsize argument back to int, undoing my 2011-03-30 change.
10690 We prefer signed types, and int is wide enough here.
10691 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
10692 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
10693 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
10694 length, not size_t. Use ptrdiff_t for index, not int.
10695 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
10696 possibility of integer overflow.

10724 Prefer int to unsigned where either will do.
10725 (tiff_handler): New function, combining the cores of the
10726 old tiff_error_handler and tiff_warning_handler.
10727 This function is rewritten to use vsnprintf and thereby avoid
10728 stack buffer overflows. It uses only the features of vsnprintf
10729 that are common to both POSIX and native Microsoft.
10730 (tiff_error_handler, tiff_warning_handler): Use it.
10731 (tiff_load, gif_load, imagemagick_load_image):
10732 Don't assume :index value fits in 'int'.
10733 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
10734 (imagemagick_load_image): Check that crop parameters fit into
10735 the integer types that MagickCropImage accepts. Don't assume
10736 Vimagemagick_render_type has a nonnegative value. Don't assume
10737 size_t fits in 'long'.
10738 (gs_load): Use printmax_t to print the widest integers possible.

10741 2011-08-26 Eli Zaretskii <eliz@gnu.org>
10743 * xdisp.c (redisplay_window): Don't force window start if point

10748 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
10749 the display spec is of the form `(space ...)'.
10750 (handle_display_spec): Return the value returned by
10751 handle_single_display_spec, not just 1 or zero.
10752 (handle_single_display_spec): If the display spec is of the form
10753 `(space ...)', and specifies display in the text area, return 2
10755 (try_cursor_movement): Check for the need to scroll more
10756 accurately, and prefer exact match for point under bidi.
10757 Don't advance `row' beyond the last row of the window.
10759 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
10760 into disp_prop; all users changed.

10774 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
10775 buffers, return left-to-right.
10776 (set_cursor_from_row): Consider candidate row a win if its glyph
10777 represents a newline and point is on that newline. Fixes cursor
10778 positioning on the newline at EOL of R2L text within L2R
10779 paragraph, and vice versa.
10780 (try_cursor_movement): Check continued rows, in addition to
10781 continuation rows. Fixes unwarranted scroll when point enters a
10782 continued line of R2L text within an L2R paragraph, or vice versa.
10783 (cursor_row_p): Consider the case of point being equal to
10784 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
10785 from the end of a short line to the beginning of a continued line
10786 of R2L text within L2R paragraph.
10787 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

10805 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
10806 extra slot even if the purpose is char-code-property-table.
10808 2011-08-23 Eli Zaretskii <eliz@gnu.org>
10810 * xdisp.c (redisplay_window): When computing centering_position,
10811 account for the height of the header line. (Bug#8874)
10813 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
10814 instead of CHAR_TO_BYTE. Fixes a crash when a completion
10815 candidate is selected by the mouse, and that candidate has a
10816 composed character under the mouse.
10818 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
10819 coordinates reported by pos-visible-in-window-p for a composed
10820 character in column zero.
10822 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

10829 consider it a hit if to_charpos is anywhere in the range of the
10830 composed buffer positions.
10832 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
10834 * image.c (gif_load): Don't assume that each subimage has the same
10835 dimensions as the base image. Handle disposal method that is
10836 "undefined" by the gif spec (Bug#9335).
10838 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
10840 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

10846 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
10847 from an Org mode buffer to a Speedbar frame.
10849 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
10850 a composition, take its buffer position from IT->cmp_it.charpos.
10851 Fixes cursor positioning at the beginning of a line that begins
10852 with a composed character.
10854 2011-08-18 Eli Zaretskii <eliz@gnu.org>
10856 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
10857 character bidirectional type, use STRONG_L instead. Fixes crashes
10858 in a buffer produced by `describe-categories'.
10860 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
10861 members before the level stack, so they would be saved and
10862 restored when copying iterator state. Fixes incorrect reordering
10863 around TABs covered by display properties.
10865 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
10867 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

10872 (internal_condition_case_2, internal_condition_case_n):
10873 Remove unnecessary aborts (Bug#9081).
10875 2011-08-17 Eli Zaretskii <eliz@gnu.org>
10877 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
10878 has no `load' handler, try opening the file locally. (Bug#9311)
10880 2011-08-16 Ken Brown <kbrown@cornell.edu>
10882 * gmalloc.c: Expand comment.
10884 2011-08-16 Eli Zaretskii <eliz@gnu.org>

10898 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
10900 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
10901 in the static heap.
10902 [CYGWIN] (special_realloc): New function.
10903 (_realloc_internal_nolock) [CYGWIN]: Use the new function on

10935 2011-08-14 Eli Zaretskii <eliz@gnu.org>
10937 * xdisp.c (move_it_in_display_line_to): Don't invoke
10938 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
10939 ppos_it. Fixes vertical cursor motion when line beginning is
10940 covered by an image. (Bug#9296)
10942 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
10944 * nsterm.h (ns_run_ascript): Declare.

10948 (ns_run_ascript): New function.
10949 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
10950 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
10951 the event loop. Get status from as_status (Bug#7276).
10953 * nsterm.m (sendEvent): If event is NSApplicationDefined and
10954 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
10955 the event loop (Bug#7276).
10957 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
10959 * gnutls.c (QCgnutls_bootprop_priority)

10961 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
10962 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
10963 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
10964 (QCgnutls_bootprop_verify_hostname_error)

10981 (Fnetwork_interface_list): Allocate in increments of bytes instead
10982 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
10983 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
10985 (struct ifflag_def): notrailers is smart on OSX.
10986 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
10987 Get hardware address with getifaddrs if available.
10989 2011-08-12 Eli Zaretskii <eliz@gnu.org>
10991 * xdisp.c (iterate_out_of_display_property): xassert that
10992 IT->position is set to within IT->object's boundaries. Break from
10993 the loop as soon as EOB is reached; avoids infloops in redisplay
10994 when IT->position is set up wrongly due to some bug.
10995 Set IT->current to match the bidi iterator unconditionally.
10996 (push_display_prop): Allow GET_FROM_STRING as IT->method on
10997 entry. Force push_it to save on the stack the current
10998 buffer/string position, to be restored by pop_it. Fix flags in
10999 the iterator structure wrt the object coming from a display
11000 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
11001 properties. (Bug#9284)
11003 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
11005 * fontset.c (fontset_get_font_group): Add proper type checks.

11033 restore_point_unwind (Bug#5984).
11035 2011-08-07 Juri Linkov <juri@jurta.org>
11037 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
11038 to show the arg `TIME' instead of `TIMEVAL'.
11040 2011-08-06 Eli Zaretskii <eliz@gnu.org>
11042 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
11043 display property strides EOL and includes a newline, as in
11044 longlines-mode. (Bug#9254)
11045 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
11046 word-wrap under bidirectional display. (Bug#9224)
11048 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
11049 is non-zero, even if the data buffer is NULL. Fixes a crash in
11050 vertical-motion with longlines-mode. (Bug#9254)
11052 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11054 * bidi.c <bidi_cache_total_alloc>: Now static.
11055 (bidi_initialize): Initialize bidi_cache_total_alloc.
11057 * xdisp.c (display_line): Release buffer allocated for shelved bidi
11060 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
11061 amount allocated this far in `bidi_cache_total_alloc'.
11062 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
11063 non-zero, only free the data buffer without restoring the cache
11064 contents. All callers changed.
11066 * dispextern.h (bidi_unshelve_cache): Update prototype.
11068 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
11069 (move_it_in_display_line, move_it_to)
11070 (move_it_vertically_backward, move_it_by_lines): Replace the call
11071 to xfree to an equivalent call to bidi_unshelve_cache.
11072 (move_it_in_display_line_to): Fix logic of returning
11073 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
11075 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11077 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
11078 came from a string character with a `cursor' property. (Bug#9229)

11086 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
11088 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
11090 * regex.c (re_iswctype): Remove some redundant boolean conversions.
11092 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11094 * xterm.c (x_find_topmost_parent): New function.
11095 (x_set_frame_alpha): Find topmost parent window with
11096 x_find_topmost_parent and set the property there also (bug#9181).
11097 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
11099 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>

11125 for a display string or property. If found, set DISP_PROP_P
11128 * bidi.c (bidi_fetch_char): Accept an additional argument
11129 DISP_PROP_P, and pass it to compute_display_string_pos.
11130 Only handle text covered by a display string if DISP_PROP_P is returned
11131 non-zero. All callers of bidi_fetch_char changed.
11133 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
11135 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.

11151 BIDI_IT_PREV, and store into it the state of the bidi iterator had
11153 (reseat_at_next_visible_line_start): Use the bidi iterator state
11154 returned by forward_to_next_line_start to restore the state of
11155 it->bidi_it after backing up to previous newline. (Bug#9212)
11157 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
11159 * regex.c (re_comp): Protoize.
11160 (re_exec): Fix return type.
11161 (regexec): Fix type of `ret'. (Bug#9203)
11163 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11165 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
11166 This is needed if max-image-size is a floating-point number.
11168 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11170 * print.c (print_object): Print empty symbol as ##.

11181 contents (Bug#9176).
11182 (EmacsTooltip -init): Remove bezels and add shadows to
11185 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
11186 or scroll bar (Bug#8470).
11188 * nsfont.m (nsfont_open): Remove assignment to voffset and

11192 * nsterm.h (nsfont_info): Remove voffset field.
11194 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11196 Implement strike-through and overline on NextStep (Bug#8863).
11198 * nsfont.m (nsfont_open): Use underline position provided by font,

11215 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11217 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11218 Without this fix, if a signal arrives just after memory fills up,
11219 'malloc' might be invoked reentrantly.
11221 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11222 In other words, assume that every image size is allowed, on non-X
11223 hosts. This assumption is probably wrong, but it lets Emacs compile.
11225 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11227 * regex.c (re_iswctype): Convert return values to boolean.

11237 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11239 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11241 Integer signedness and overflow and related fixes. (Bug#9079)
11243 * bidi.c: Integer size and overflow fixes.
11244 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
11245 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
11246 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11247 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11248 (bidi_find_other_level_edge):
11249 Use ptrdiff_t instead of EMACS_INT where either will do.
11250 This works better on 32-bit hosts configured --with-wide-int.
11251 (bidi_cache_ensure_space): Check for size-calculation overflow.
11252 Use % rather than repeated addition, for better worst-case speed.
11253 Don't set bidi_cache_size until after xrealloc returns, because it
11255 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11256 (bidi_cache_ensure_space): Also check that the bidi cache size
11257 does not exceed that of the largest Lisp string or buffer. See Eli
11258 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11260 * alloc.c (__malloc_size_t): Remove.
11261 All uses replaced by size_t. See Andreas Schwab's note
11262 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11264 * image.c: Improve checking for integer overflow.
11265 (check_image_size): Assume that f is nonnull, since
11266 it is always nonnull in practice. This is one less thing to
11267 worry about when checking for integer overflow later.
11268 (x_check_image_size): New function, which checks for integer
11269 overflow issues inside X.
11270 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11271 This removes the need for a memory_full check.
11272 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11273 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11274 (xbm_read_bitmap_data): Change locals back to 'int', since
11275 their values must fit in 'int'.
11276 (xpm_load_image, png_load, tiff_load):
11277 Invoke x_create_x_image_and_pixmap earlier,
11278 to avoid much needless work if the image is too large.
11279 (tiff_load): Treat overly large images as if
11280 x_create_x_image_and_pixmap failed, not as malloc failures.
11281 (gs_load): Use x_check_image_size.
11283 * gtkutil.c: Omit integer casts.
11284 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11285 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11287 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11289 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11290 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11291 would wrongly return t on a 64-bit host.
11293 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11294 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11295 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11296 and therefore cause GCC to emit a bogus diagnostic in some cases.
11298 * image.c: Integer signedness and overflow and related fixes.
11299 This is not an exhaustive set of fixes, but it's time to
11300 record what I've got.
11301 (lookup_pixel_color, check_image_size): Remove redundant decls.
11302 (check_image_size): Don't assume that arbitrary EMACS_INT values
11303 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11304 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11305 (tiff_load, imagemagick_load_image):
11306 Check for overflow in size calculations.
11307 (x_create_x_image_and_pixmap): Remove unnecessary test for
11308 xmalloc returning NULL; that can't happen.
11309 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11310 (xpm_color_bucket): Use better integer hashing function.
11311 (xpm_cache_color): Don't possibly over-allocate memory.
11312 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11313 (gif_memory_source):
11314 Use ptrdiff_t, not int or size_t, to record sizes.
11315 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11316 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11317 either works, as we prefer signed integers.
11318 (tiff_read_from_memory, tiff_write_from_memory):
11319 Return tsize_t, not size_t, since that's what the TIFF API wants.
11320 (tiff_read_from_memory): Don't fail simply because the read would
11321 go past EOF; instead, return a short read.
11322 (tiff_load): Omit no-longer-needed casts.
11323 (Fimagemagick_types): Don't assume size fits into 'int'.
11325 Improve hashing quality when configured --with-wide-int.
11326 * fns.c (hash_string): New function, taken from sxhash_string.
11327 Do not discard information about ASCII character case; this
11328 discarding is no longer needed.
11329 (sxhash-string): Use it. Change sig to match it. Caller changed.
11330 * lisp.h: Declare it.
11331 * lread.c (hash_string): Remove, since we now use fns.c's version.
11332 The fns.c version returns a wider integer if --with-wide-int is
11333 specified, so this should help the quality of the hashing a bit.
11335 * emacs.c: Integer overflow minor fix.
11336 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11337 Define only if GNU_LINUX.
11338 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11340 * dispnew.c: Integer signedness and overflow fixes.
11341 Remove unnecessary forward decls, that were a maintenance hassle.
11342 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11344 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11345 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11346 (prepare_desired_row, line_draw_cost):
11347 Use int, not unsigned, where either works.
11348 (save_current_matrix, restore_current_matrix):
11349 Use ptrdiff_t, not size_t, where either works.
11350 (init_display): Check for overflow more accurately, and without
11351 relying on undefined behavior.
11353 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11354 Remove, replacing with the new symbols in lisp.h. All uses changed.
11355 * fileio.c (make_temp_name):
11356 * filelock.c (lock_file_1, lock_file):
11357 * xdisp.c (message_dolog):
11358 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11359 Use pMd etc. instead.
11360 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11361 replacing the pWIDE etc. symbols removed from editfns.c.
11363 * keyboard.h (num_input_events): Now uintmax_t.
11364 This is (very slightly) less likely to mess up due to wraparound.
11367 * buffer.c: Integer signedness fixes.
11368 (alloc_buffer_text, enlarge_buffer_text):
11369 Use ptrdiff_t rather than size_t when either will do, as we prefer
11372 * alloc.c: Integer signedness and overflow fixes.
11373 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11374 (__malloc_size_t): Default to size_t, not to int.
11375 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11376 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11377 Prefer ptrdiff_t to size_t when either would do, as we prefer
11379 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11380 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11381 Now const. Initialize with values that are in range even if char
11383 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11384 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11385 These functions do the right thing with sizes > 2**32.
11386 (check_depth): Now ptrdiff_t, not int.
11387 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11388 Adjust to new way of storing sizes. Check for size overflow bugs
11390 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11391 slightly wrong anyway, as it missed one instance of
11392 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11393 (refill_memory_reserve): Omit needless cast to size_t.
11394 (mark_object_loop_halt): Mark as externally visible.
11396 * xselect.c: Integer signedness and overflow fixes.
11397 (Fx_register_dnd_atom, x_handle_dnd_message):
11398 Use ptrdiff_t, not size_t, since we prefer signed.
11399 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11400 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11401 x_dnd_atoms_size and x_dnd_atoms_length.
11403 * doprnt.c: Prefer signed to unsigned when either works.
11405 * doprnt.c (doprnt):
11407 * xdisp.c (vmessage):
11408 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11409 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11410 prefer signed arithmetic to avoid comparison confusion.
11411 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11412 but is a bit tricky.
11414 Assume freestanding C89 headers, string.h, stdlib.h.
11415 * data.c, doprnt.c, floatfns.c, print.c:
11416 Include float.h unconditionally.
11417 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11418 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11419 * regex.c: Likewise for stddef.h, string.h.
11420 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11421 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11422 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11423 (STDC_HEADERS): Remove obsolete defines.
11424 * sysdep.c: Include limits.h unconditionally.
11426 Assume support for memcmp, memcpy, memmove, memset.
11427 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11428 * regex.c (memcmp, memcpy):
11429 Remove; we assume C89 now.
11431 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11432 (__malloc_safe_bcopy): Remove; no longer needed.
11434 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11435 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11436 well either way, and we prefer signed to unsigned.
11438 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11440 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11441 closes the connection while we're reading (bug#9182).
11443 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11445 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11446 are specified (Bug#9168).
11448 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11450 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11451 Found by GCC static checking and --with-wide-int on a 32-bit host.
11453 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11455 * xdisp.c (compute_display_string_pos): Fix logic of caching
11456 previous display string position. Initialize cached_prev_pos to
11457 -1. Fixes slow-down at the beginning of a buffer.
11459 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11461 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11462 for attrs[LFACE_FONTSET_INDEX].
11464 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11466 * xml.c (parse_region): Remove unused local
11467 that was recently introduced.
11469 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11471 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11472 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11474 * xdisp.c (move_it_in_display_line_to): Record the best matching
11475 position for TO_CHARPOS while scanning the line, and restore it on
11476 exit if none of the characters scanned was an exact match.
11477 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11478 when exact match is impossible due to invisible text, and the
11479 lines are truncated.
11481 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11483 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11486 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11488 Fix a significant slow-down of cursor motion with C-n, C-p,
11489 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11490 auto-repeat under bidi redisplay in fontified buffers.
11491 * xdisp.c (compute_stop_pos_backwards): New function.
11492 (next_element_from_buffer): Call compute_stop_pos_backwards to
11493 find a suitable prev_stop when we find ourselves before
11495 (reseat): Don't look for prev_stop, as that could mean a very long
11497 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11498 <cached_disp_overlay_modiff>: Cache for last found display string
11500 (compute_display_string_pos): Return the cached position if asked
11501 about the same buffer in the same area of character positions, and
11502 the buffer wasn't changed since the time the display string
11503 position was cached.
11505 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11507 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11508 is an integer, which is important for empty lines. (Bug#9149)
11510 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11512 * frame.c (Fmodify_frame_parameters): In tty case, update the
11513 default face if necessary (Bug#4238).
11515 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11517 * editfns.c (Fstring_to_char): No need to explain what a character
11518 is in the docstring (Bug#6576).
11520 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11522 * xml.c (parse_region): Make sure we always return a tree.
11524 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11526 * xml.c (parse_region): If a document contains only comments,
11529 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11531 * xml.c (make_dom): Return comments, too.
11533 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11536 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11537 and the surrounding thread.
11538 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11539 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11540 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11542 * s/openbsd.h (BROKEN_SIGIO): Define.
11543 * unexelf.c (unexec) [__OpenBSD__]:
11544 Don't update the .mdebug section of the Alpha COFF symbol table.
11546 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11548 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11551 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11553 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11554 This fixes some race conditions on the permissions of any newly
11557 * alloc.c (valid_pointer_p): Use pipe, not open.
11558 This fixes some permissions issues when debugging.
11560 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11561 If fchown fails to set both uid and gid, try to set just gid,
11562 as that is sometimes allowed. Adjust the file's mode to eliminate
11563 setuid or setgid bits that are inappropriate if fchown fails.
11565 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11567 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11568 to compare Lisp_Objects.
11569 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11570 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11571 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11573 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11575 * lread.c (read_integer): Unread even EOF character.
11576 (read1): Likewise. Properly record start position of symbol.
11578 * lread.c (read1): Read `#:' as empty uninterned symbol if no
11579 symbol character follows.
11581 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11583 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11584 This works around a problem with the previous change to Fcopy_file.
11585 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11586 and without this change, GCC might complain about discarding
11587 fchown's return value.
11589 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11591 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11593 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11595 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11597 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11599 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11600 it's used from the C level.
11602 * process.c: Use the same condition for POLL_FOR_INPUT in both
11603 keyboard.c and process.c (bug#1858).
11605 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11607 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11608 (Fgnutls_boot): Use it.
11610 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11612 * doc.c (Fsubstitute_command_keys): Revert last change.
11614 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11616 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11617 quotes the next character, and doesn't affect other longer
11618 sequences (bug#8935).
11620 * lread.c (syms_of_lread): Clarify that is isn't only
11621 `eval-buffer' and `eval-defun' that's affected by
11622 `lexical-binding' (bug#8460).
11624 2011-07-15 Eli Zaretskii <eliz@gnu.org>
11626 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11627 bidi redisplay when a line includes both an image and is truncated.
11629 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11631 Fix minor problems found by static checking.
11632 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11633 (elsz): Now a signed constant, not a size_t var. We prefer signed
11634 types to unsigned, to avoid integer comparison confusion. Without
11635 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
11636 "cannot optimize loop, the loop counter may overflow", a symptom
11638 * indent.c (Fvertical_motion): Mark locals as initialized.
11639 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
11641 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
11643 * search.c (Fre_search_backward): Mention `case-fold-search' in
11644 all the re_search_* functions (bug#8138).
11646 * keyboard.c (Fopen_dribble_file): Document when the file is
11649 2011-07-14 Eli Zaretskii <eliz@gnu.org>
11651 * bidi.c (bidi_dump_cached_states): Fix format of displaying
11654 Support bidi reordering of display and overlay strings.
11655 * xdisp.c (compute_display_string_pos)
11656 (compute_display_string_end): Accept additional argument STRING.
11657 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
11658 (reseat_to_string): Initialize bidi_it->string.s and
11659 bidi_it->string.schars.
11660 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
11661 NULL (avoids a crash in bidi_paragraph_init).
11662 Initialize itb.string.lstring.
11663 (init_iterator): Call bidi_init_it only of a valid
11664 buffer position was specified. Initialize paragraph_embedding to
11666 (reseat_to_string): Initialize the bidi iterator.
11667 (display_string): If we need to ignore text properties of
11668 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
11669 original value of -1 will not work with bidi.)
11670 (compute_display_string_pos): First arg is now struct
11671 `text_pos *'; all callers changed. Support display properties on
11673 (compute_display_string_end): Support display properties on Lisp
11675 (init_iterator, reseat_1, reseat_to_string): Initialize the
11676 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
11677 when iterating on a string not from display properties).
11678 (compute_display_string_pos, compute_display_string_end):
11679 Fix calculation of the object to scan. Fixes an error when using
11681 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
11682 base_level_stop; instead, set base_level_stop to BEGV.
11683 Fixes crashes in vertical-motion.
11684 (next_element_from_buffer): Improve commentary for when
11685 the iterator is before prev_stop.
11686 (init_iterator): Initialize bidi_p from the default value of
11687 bidi-display-reordering, not from buffer-local value. Use the
11688 buffer-local value only if initializing for buffer iteration.
11689 (handle_invisible_prop): Support invisible properties on strings
11690 that are being bidi-reordered.
11691 (set_iterator_to_next): Support bidi reordering of C strings and
11693 (next_element_from_string): Support bidi reordering of Lisp
11695 (handle_stop_backwards): Support Lisp strings as well.
11696 (display_string): Support display of R2L glyph rows.
11697 Use IT_STRING_CHARPOS when displaying from a Lisp string.
11698 (init_iterator): Don't initialize it->bidi_p for strings
11700 (reseat_to_string): Initialize it->bidi_p for strings here.
11701 (next_element_from_string, next_element_from_c_string)
11702 (next_element_from_buffer): Add xassert's for correspondence
11703 between IT's object being iterated and it->bidi_it.string
11705 (face_before_or_after_it_pos): Support bidi iteration.
11706 (next_element_from_c_string): Handle the case of the first string
11707 character that is not the first one in the visual order.
11708 (get_visually_first_element): New function, refactored from common
11709 parts of next_element_from_buffer, next_element_from_string, and
11710 next_element_from_c_string.

12161 * alloc.c (mark_buffer):
12162 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
12163 (clone_per_buffer_values): Don't assume that
12164 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
12165 This isn't true in general, and it's particularly not true
12166 if Emacs is configured with --with-wide-int.
12167 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
12168 New macros, used in the buffer.c change.

12202 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
12204 Random fixes. E.g., (random) never returned negative values.
12205 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
12206 subseconds part to the entropy, as that's a bit more random.
12207 Prefer signed to unsigned, since the signedness doesn't matter and
12208 in general we prefer signed. When given a limit, use a
12209 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12210 latter isn't right if USE_2_TAGS_FOR_INTS.
12211 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12212 not 0..VALMASK. Don't discard "excess" bits that random () returns.
12214 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
12216 * textprop.c (text_property_stickiness):
12217 Obey Vtext_property_default_nonsticky.
12218 (syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.

12224 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
12225 This is more efficient than Ffile_directory_p and avoids a minor race.
12227 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
12229 * buffer.c (Foverlay_put): Say what the return value is
12232 * fileio.c (barf_or_query_if_file_exists): Check first if the file
12233 is a directory before asking whether to use the file name
12235 (barf_or_query_if_file_exists): Make the "File is a directory"
12236 error be more correct.
12238 * fns.c (Frequire): Remove the mention of the .gz files, since
12239 that's installation-specific, but keep the mention of
12240 `get-load-suffixes'.
12242 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
12244 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

12250 (syms_of_gnutls): Remove duplicate DEFSYM for
12251 Qgnutls_bootprop_verify_hostname_error, an error for
12252 Qgnutls_bootprop_verify_error (which is no longer used).
12254 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
12255 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
12256 Also (re)move comments that are misplaced or no longer relevant.
12258 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12260 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

12319 (syms_of_keymap): Defsubr make-composed-keymap.
12320 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

12357 * eval.c (struct backtrace): Simplify and port the data structure.
12358 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12359 signed bit field, as this assumption is not portable and it makes
12360 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12361 "char debug_on_exit : 1" as this is not portable either; instead,
12362 use the portable "unsigned int debug_on_exit : 1". Remove unused
12363 member evalargs. Remove obsolete comments about cc bombing out.
12365 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

12589 * xterm.c (x_check_font): Remove unused local.
12590 * scroll.c (CHECK_BOUNDS):
12591 * xfaces.c (cache_fache): Rename local to avoid shadowing.
12592 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
12593 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
12594 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
12595 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
12597 (debug_method_add): Use va_list and vsprintf rather than relying
12598 on undefined behavior with wrong number of arguments.
12599 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12600 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12601 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12602 since we're not interested in debugging glyphs with old libraries.
12603 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12604 GCC 4.6.0's static checking.
12606 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12608 Integer overflow and signedness fixes (Bug#8873).
12609 A few related buffer overrun fixes, too.

12617 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
12618 (x_create_bitmap_from_xpm_data):
12619 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
12620 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
12622 * xfaces.c (load_pixmap):
12623 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
12624 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
12625 (.bitmaps_last, struct x_output.icon_bitmap):
12626 Use ptrdiff_t, not int, for bitmap indexes.
12627 (x_allocate_bitmap_record): Check for size overflow.
12628 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
12630 Use ptrdiff_t, not int, for overlay counts.
12631 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
12632 * editfns.c (overlays_around, get_pos_property):
12633 * textprop.c (get_char_property_and_overlay):
12634 * xdisp.c (next_overlay_change, note_mouse_highlight):
12635 * xfaces.c (face_at_buffer_position):
12636 * buffer.c (OVERLAY_COUNT_MAX): New macro.
12637 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
12638 (Fnext_overlay_change, Fprevious_overlay_change)
12639 (mouse_face_overlay_overlaps, Foverlays_in):
12640 Use ptrdiff_t, not int, for sizes.
12641 (overlays_at, overlays_in): Check for size-calculation overflow.
12643 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
12645 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
12646 (x_session_initialize): Do not assume string length fits in int.
12648 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
12649 This is unlikely, but can occur if DPI is outlandish.
12651 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
12652 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
12654 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
12655 * xrdb.c (magic_file_p, search_magic_path):
12656 Omit last arg SUFFIX; it was always 0. All callers changed.
12657 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
12659 * xfont.c (xfont_match): Avoid need for strlen.
12661 * xfns.c: Don't assume strlen fits in int.
12662 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
12664 * xdisp.c (message_log_check_duplicate): Return intmax_t,
12665 not unsigned long, as we prefer signed integers. All callers changed.
12666 Detect integer overflow in repeat count.
12667 (message_dolog): Don't assume print length fits in 39 bytes.
12668 (display_mode_element): Don't assume strlen fits in int.
12670 * termcap.c: Don't assume sizes fit in int and never overflow.
12671 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
12672 (gobble_line): Check for size-calculation overflow.
12674 * minibuf.c (Fread_buffer):
12675 * lread.c (intern, intern_c_string):
12676 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
12677 Don't assume string length fits in int.
12679 * keyboard.c (parse_tool_bar_item):
12680 * gtkutil.c (style_changed_cb): Avoid need for strlen.
12682 * font.c: Don't assume string length fits in int.
12683 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
12684 Use ptrdiff_t, not int.
12685 (font_intern_prop): Don't assume string length fits in int.
12686 Don't assume integer property fits in fixnum.
12687 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
12689 * filelock.c: Fix some buffer overrun and integer overflow issues.
12690 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
12691 Reformulate so as not to need the command string.
12692 Invoke gzip -cd rather than gunzip, as it's more portable.
12693 (lock_info_type, lock_file_1, lock_file):
12694 Don't assume pid_t and time_t fit in unsigned long.
12695 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
12696 (current_lock_owner): Prefer signed type for sizes.
12697 Use memcpy, not strncpy, where memcpy is what is really wanted.
12698 Don't assume (via atoi) that time_t and pid_t fit in int.
12699 Check for time_t and/or pid_t out of range, e.g., via a network share.
12700 Don't alloca where an auto var works fine.
12702 * fileio.c: Fix some integer overflow issues.
12703 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
12704 Don't assume string length fits in int.
12705 (directory_file_name): Don't assume string length fits in long.
12706 (make_temp_name): Don't assume pid fits in int, or that its print
12707 length is less than 20.
12709 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
12711 * coding.c (make_subsidiaries): Don't assume string length fits in int.
12713 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
12715 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
12716 We prefer signed integers, even for size calculations.
12718 * emacs.c: Don't assume string length fits in 'int'.
12719 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
12720 (main): Don't invoke strlen when not needed.
12722 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
12723 (XD_DEBUG_MESSAGE): Don't waste a byte.
12725 * callproc.c (getenv_internal_1, getenv_internal)
12726 (Fgetenv_internal):
12727 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
12729 * lread.c (invalid_syntax): Omit length argument.
12730 All uses changed. This doesn't fix a bug, but it simplifies the
12731 code away from its former Hollerith-constant appearance, and it's
12732 one less 'int' to worry about when looking at integer-overflow issues.
12733 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
12735 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
12736 This didn't break anything, but it didn't help either.
12737 It's confusing to put a bogus integer in a place where the actual
12738 value does not matter.
12739 (LIST_END_P): Remove unused macro and its bogus comment.
12740 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
12742 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
12743 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
12745 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
12746 We prefer signed types, and the value cannot exceed the EMACS_INT
12747 range anyway (because otherwise the length would not be representable).
12748 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
12749 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
12750 This avoids a GCC warning when WIDE_EMACS_INT.
12752 * indent.c (sane_tab_width): New function.
12753 (current_column, scan_for_column, Findent_to, position_indentation)
12754 (compute_motion): Use it. This is just for clarity.
12755 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
12757 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
12759 * lisp.h (lint_assume): New macro.
12760 * composite.c (composition_gstring_put_cache):
12761 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
12763 * editfns.c, insdel.c:
12764 Omit unnecessary forward decls, to simplify future changes.
12766 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
12768 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
12770 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
12771 Use much-faster test for byte-length change.
12772 Don't assume string byte-length fits in 'int'.
12773 Check that character arg fits in 'int'.
12774 (mapcar1): Declare byte as byte, for clarity.
12776 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
12778 * fns.c (concat): Catch string overflow earlier.
12779 Do not rely on integer wraparound.
12781 * dispextern.h (struct it.overlay_strings_charpos)
12782 (struct it.selective): Now EMACS_INT, not int.
12783 * xdisp.c (forward_to_next_line_start)
12784 (back_to_previous_visible_line_start)
12785 (reseat_at_next_visible_line_start, next_element_from_buffer):
12786 Don't arbitrarily truncate the value of 'selective' to int.
12788 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
12790 * composite.c: Don't truncate sizes to 'int'.
12791 (composition_gstring_p, composition_reseat_it)
12792 (composition_adjust_point): Use EMACS_INT, not int.
12793 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
12794 not EMACS_UINT, for indexes.
12796 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
12798 * buffer.c: Include <verify.h>.
12799 (struct sortvec.priority, struct sortstr.priority):
12800 Now EMACS_INT, not int.
12801 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
12802 (struct sortstr.size, record_overlay_string)
12803 (struct sortstrlist.size, struct sortlist.used):
12804 Don't truncate size to int.
12805 (record_overlay_string): Check for size-calculation overflow.
12806 (init_buffer_once): Check at compile-time, not run-time.
12808 2011-06-22 Jim Meyering <meyering@redhat.com>
12810 Don't leak an XBM-image-sized buffer
12811 * image.c (xbm_load): Free the image buffer after using it.
12813 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
12816 * composite.c (find_automatic_composition): Omit needless 'return 0;'
12817 that Sun C diagnosed.
12818 * fns.c (secure_hash): Fix pointer signedness issue.
12819 * intervals.c (static_offset_intervals): New function.
12820 (offset_intervals): Use it.
12822 2011-06-21 Leo Liu <sdl.web@gmail.com>
12825 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
12828 * fns.c (secure_hash): Rename from crypto_hash_function and change
12829 the first arg to accept symbols.
12830 (Fsecure_hash): New primitive.
12831 (syms_of_fns): New symbols.
12833 2011-06-20 Deniz Dogan <deniz@dogan.se>
12835 * process.c (Fset_process_buffer): Clarify return value in
12838 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
12840 * dispnew.c (add_window_display_history): Use BVAR.
12842 * xdisp.c (debug_method_add): Use BVAR.
12843 (check_window_end, dump_glyph_matrix, dump_glyph)
12844 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
12846 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
12849 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
12850 check till after the cache is created in init_frame_faces.
12852 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
12854 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
12856 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
12858 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
12859 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
12860 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
12862 Improve buffer-overflow checking (Bug#8873).
12863 * fileio.c (Finsert_file_contents):
12864 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
12865 Remove the old (too-loose) buffer overflow checks.
12866 They weren't needed, since make_gap checks for buffer overflow.
12867 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
12868 The old code merely checked for Emacs fixnum overflow, and relied
12869 on undefined (wraparound) behavior. The new code avoids undefined
12870 behavior, and also checks for ptrdiff_t and/or size_t overflow.
12872 * editfns.c (Finsert_char): Don't dump core with very negative counts.
12873 Tune. Don't use wider integers than needed. Don't use alloca.
12874 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
12876 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
12878 * insdel.c, lisp.h (buffer_overflow): New function.
12879 (insert_from_buffer_1, replace_range, replace_range_2):
12880 * insdel.c (make_gap_larger):
12881 * editfns.c (Finsert_char):
12882 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
12884 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
12886 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
12888 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
12890 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
12891 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
12893 * fileio.c: Don't assume EMACS_INT fits in off_t.
12894 (emacs_lseek): New static function.
12895 (Finsert_file_contents, Fwrite_region): Use it.
12896 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
12898 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
12900 * fns.c: Don't overflow int when computing a list length.
12901 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
12902 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
12903 truncation on 64-bit hosts. Check for QUIT every
12904 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
12905 faster and is responsive enough.
12906 (Flength): Report an error instead of overflowing an integer.
12907 (Fsafe_length): Return a float if the value is not representable
12908 as a fixnum. This shouldn't happen except in contrived situations.
12909 (Fnthcdr, Fsort): Don't assume list length fits in int.
12910 (Fcopy_sequence): Don't assume vector length fits in int.
12912 * alloc.c: Check that resized vectors' lengths fit in fixnums.
12913 (header_size, word_size): New constants.
12914 (allocate_vectorlike): Don't check size overflow here.
12915 (allocate_vector): Check it here instead, since this is the only
12916 caller of allocate_vectorlike that could cause overflow.
12917 Check that the new vector's length is representable as a fixnum.
12919 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
12920 The previous code was bogus. For example, next_almost_prime (32)
12921 returned 39, which is undesirable as it is a multiple of 3; and
12922 next_almost_prime (24) returned 25, which is a multiple of 5 so
12923 why was the code bothering to check for multiples of 7?
12925 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
12927 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
12929 Variadic C functions now count arguments with ptrdiff_t.
12930 This partly undoes my 2011-03-30 change, which replaced int with size_t.
12931 Back then I didn't know that the Emacs coding style prefers signed int.
12932 Also, in the meantime I found a few more instances where arguments
12933 were being counted with int, which may truncate counts on 64-bit
12934 machines, or EMACS_INT, which may be unnecessarily wide.
12935 * lisp.h (struct Lisp_Subr.function.aMANY)
12936 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
12937 Arg counts are now ptrdiff_t, not size_t.
12938 All variadic functions and their callers changed accordingly.
12939 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
12940 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
12941 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
12942 * callint.c (Fcall_interactively): Check arg count for overflow,
12943 to avoid potential buffer overrun. Use signed char, not 'int',
12944 for 'varies' array, so that we needn't bother to check its size
12945 calculation for overflow.
12946 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
12947 * eval.c (apply_lambda):
12948 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
12949 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
12950 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
12952 * callint.c (Fcall_interactively): Don't use index var as event count.
12954 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
12955 * mem-limits.h (SIZE): Remove; no longer used.
12957 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
12959 Remove unnecessary casts.
12960 * xterm.c (x_term_init):
12961 * xfns.c (x_set_border_pixel):
12962 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
12963 These aren't needed now that we assume ANSI C.
12965 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
12966 It's more likely to cause problems (due to unsigned overflow)
12969 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
12971 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
12973 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
12975 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
12977 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
12979 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
12981 GLYPH_CODE_FACE returns EMACS_INT, not int.
12982 * dispextern.h (merge_faces):
12983 * xfaces.c (merge_faces):
12984 * xdisp.c (get_next_display_element, next_element_from_display_vector):
12985 Don't assume EMACS_INT fits in int.
12987 * character.h (CHAR_VALID_P): Remove unused parameter.
12988 * fontset.c, lisp.h, xdisp.c: All uses changed.
12990 * editfns.c (Ftranslate_region_internal): Omit redundant test.
12992 * fns.c (concat): Minor tuning based on overflow analysis.
12993 This doesn't fix any bugs. Use int to hold character, instead
12994 of constantly refetching from Emacs object. Use XFASTINT, not
12995 XINT, for value known to be a character. Don't bother comparing
12996 a single byte to 0400, as it's always less.
12998 * floatfns.c (Fexpt):
12999 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
13001 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
13004 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
13006 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
13007 Without this fix, on a 64-bit host (aset S 0 4294967386) would
13008 incorrectly succeed when S was a string, because 4294967386 was
13009 truncated before it was used.
13011 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13012 Otherwise, an out-of-range integer could cause undefined behavior
13015 * composite.c: Use int, not EMACS_INT, for characters.
13016 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13017 EMACS_INT, for values that are known to be in character range.
13018 This doesn't fix any bugs but is the usual style inside Emacs and
13019 may generate better code on 32-bit machines.
13021 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13022 This is for reasons similar to the recent CHAR_STRING fix.
13023 * charset.c (Fencode_char): Check that character arg is actually
13024 a character. Pass an int to ENCODE_CHAR.
13025 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13026 wider than 'int', as a compile-time check to prevent future regressions
13029 * character.c (char_string): Remove unnecessary casts.
13031 Make sure a 64-bit char is never passed to CHAR_STRING.
13032 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13033 by silently ignoring the top 32 bits, allowing some values
13034 that were far too large to be valid characters.
13035 * character.h: Include <verify.h>.
13036 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13037 arguments are no wider than unsigned, as a compile-time check
13038 to prevent future regressions in this area.
13040 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
13041 (Fsubst_char_in_region):
13043 * xdisp.c (decode_mode_spec_coding):
13044 Adjust to CHAR_STRING's new requirement.
13045 * editfns.c (Finsert_char, Fsubst_char_in_region):
13046 * fns.c (concat): Check that character args are actually
13047 characters. Without this test, these functions did the wrong
13048 thing with wildly out-of-range values on 64-bit hosts.
13050 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13051 These casts should not be needed on 32-bit hosts, either.
13052 * keyboard.c (read_char):
13053 * lread.c (Fload): Remove casts to unsigned.
13055 * lisp.h (UNSIGNED_CMP): New macro.
13056 This fixes comparison bugs on 64-bit hosts.
13057 (ASCII_CHAR_P): Use it.
13058 * casefiddle.c (casify_object):
13059 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
13060 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
13061 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
13062 * dispextern.h (FACE_FROM_ID):
13063 * keyboard.c (read_char): Use UNSIGNED_CMP.
13065 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
13066 not to EMACS_INT, to avoid GCC warning.
13068 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13070 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13071 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
13072 isn't needed on 32-bit machines.
13074 * buffer.c (Fgenerate_new_buffer_name):
13075 Use EMACS_INT for count, not int.
13076 (advance_to_char_boundary): Return EMACS_INT, not int.
13078 * data.c (Qcompiled_function): Now static.
13080 * window.c (window_body_lines): Now static.
13082 * image.c (gif_load): Rename local to avoid shadowing.
13084 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
13085 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
13086 * alloc.c (make_save_value): Integer argument is now of type
13087 ptrdiff_t, not int.
13088 (mark_object): Use ptrdiff_t, not int.
13089 * lisp.h (pD): New macro.
13090 * print.c (print_object): Use it.
13092 * alloc.c: Use EMACS_INT, not int, to count objects.
13093 (total_conses, total_markers, total_symbols, total_vector_size)
13094 (total_free_conses, total_free_markers, total_free_symbols)
13095 (total_free_floats, total_floats, total_free_intervals)
13096 (total_intervals, total_strings, total_free_strings):
13097 Now EMACS_INT, not int. All uses changed.
13098 (Fgarbage_collect): Compute overall total using a double, so that
13099 integer overflow is less likely to be a problem. Check for overflow
13100 when converting back to an integer.
13101 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
13102 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
13103 These were 'int' variables that could overflow on 64-bit hosts;
13104 they were never used, so remove them instead of repairing them.
13105 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
13106 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
13107 Previously, this ceilinged at INT_MAX, but that doesn't work on
13109 (allocate_pseudovector): Don't use EMACS_INT when int would do.
13111 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
13112 (allocate_vectorlike): Check for ptrdiff_t overflow.
13113 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13114 when a (possibly-narrower) signed value would do just as well.
13115 We prefer using signed arithmetic, to avoid comparison confusion.
13117 * alloc.c: Catch some string size overflows that we were missing.
13118 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
13119 for convenience in STRING_BYTES_MAX.
13120 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
13121 The definition here is exact; the one in lisp.h was approximate.
13122 (allocate_string_data): Check for string overflow. This catches
13123 some instances we weren't catching before. Also, it catches
13124 size_t overflow on (unusual) hosts where SIZE_MAX <= min
13125 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
13126 and ptrdiff_t and EMACS_INT are both 64 bits.
13128 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
13129 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
13130 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
13132 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
13134 * alloc.c (Fmake_string): Check for out-of-range init.
13136 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
13138 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
13140 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
13142 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
13143 xg_get_default_scrollbar_width.
13145 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.

13153 and height if HAVE_GTK3 (Bug#8505).
13154 (scroll_bar_width_for_theme): New variable.
13155 (update_theme_scrollbar_width): New function.
13156 (xg_get_default_scrollbar_width): Move code to

13160 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
13162 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

13166 * frame.c (make_frame): Call other_buffer_safely instead of
13169 * window.c (temp_output_buffer_show): Call display_buffer with
13170 second argument Vtemp_buffer_show_specifiers and reset latter
13171 immediately after the call.
13172 (Vtemp_buffer_show_specifiers): New variable.
13173 (auto_window_vscroll_p, next_screen_context_lines)
13174 (Vscroll_preserve_screen_position): Remove leading asterisks from

13717 (bidi_level_of_next_char): Don't try to lookup the cache for the
13718 next/previous character if nothing is cached there yet, or if we
13719 were just reseat()'ed to a new position.
13721 * xdisp.c (set_cursor_from_row): Set start and stop points
13722 according to the row's direction when priming the loop that looks
13723 for the glyph on which to display cursor.

13725 (display_prop_intangible_p): Reimplement to call
13726 handle_display_spec instead of single_display_spec_intangible_p.

13737 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
13738 value of a `display' property is a "replacing spec".
13739 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
13740 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
13741 the display property, but just return a value indicating whether
13742 the display property will replace the characters it covers.
13743 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
13744 frame_window_p members of struct bidi_it.

13770 * gnutls.c: Use Emacs's memory allocators.
13771 Without this change, the gnutls library would invoke malloc etc.
13772 directly, which causes problems on non-SYNC_INPUT hosts, and which
13773 runs afoul of improving memory_full behavior. (Bug#8761)
13774 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
13775 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
13776 xfree instead of the default malloc, realloc, free.
13777 (Fgnutls_boot): No need to check for memory allocation failure,
13778 since xmalloc does that for us.

13807 need to be updated by these changes.
13808 * fns.c (make_hash_table, maybe_resize_hash_table):
13809 Check for integer overflow with large hash tables.
13810 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
13811 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
13812 (SXHASH_REDUCE): New macro.
13813 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
13814 Use it instead of discarding useful hash info with large hash values.
13815 (sxhash_float): New function.
13816 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
13817 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
13818 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
13819 Rewrite to use FIXNUM_BITS, as this simplifies things.
13820 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
13821 Adjust signatures to match updated version of code.
13822 (consing_since_gc): Now EMACS_INT, since a single hash table can
13823 use more than INT_MAX bytes.

13872 Make it possible to run ./temacs.
13874 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
13875 syms_of_callproc does the same thing. Remove test for

13893 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
13895 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
13897 * eval.c (Qdebug): Now static.
13898 * lisp.h (Qdebug): Remove decl. This reverts a part of the
13899 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
13900 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
13902 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
13904 * image.c: Various fixes to ImageMagick code comments.
13905 (Fimagemagick_types): Doc fix.
13907 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
13909 Minor fixes prompted by GCC 4.6.0 warnings.
13911 * xselect.c (converted_selections, conversion_fail_tag): Now static.
13913 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
13914 (x_clipboard_manager_save_all): Move extern decl to ...
13915 * xterm.h: ... here, so that it can be checked for consistency.
13917 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
13919 * xselect.c (x_clipboard_manager_save_frame)
13920 (x_clipboard_manager_save_all): New functions.
13921 (Fx_clipboard_manager_save): Lisp function deleted.
13923 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
13924 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
13926 * xterm.h: Update prototype.
13928 2011-05-28 William Xu <william.xwl@gmail.com>
13930 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
13931 exiting (Bug#8239).
13933 2011-05-28 Jim Meyering <meyering@redhat.com>
13935 Avoid a sign-extension bug in crypto_hash_function.
13936 * fns.c (to_uchar): Define.
13937 (crypto_hash_function): Use it to convert some newly-signed
13938 variables to unsigned, to avoid sign-extension bugs. For example,
13939 without this change, (md5 "truc") would evaluate to
13940 45723a2aff78ff4fff7fff1114760e62 rather than the expected
13941 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
13942 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
13944 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13946 Integer overflow fixes.
13948 * dbusbind.c: Serial number integer overflow fixes.
13949 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
13950 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
13951 to hold a serial number that is too large for a fixnum.
13952 (Fdbus_method_return_internal, Fdbus_method_error_internal):
13953 Check for serial numbers out of range. Decode any serial number
13954 that was so large that it became a float. (Bug#8722)
13956 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
13957 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13958 Use XFASTINT rather than XUINT when numbers are nonnegative.
13959 (xd_append_arg, Fdbus_method_return_internal):
13960 (Fdbus_method_error_internal): Likewise. Also, for unsigned
13961 arguments, check that Lisp number is nonnegative, rather than
13962 silently wrapping negative numbers around. (Bug#8722)
13963 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
13966 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
13968 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
13970 ccl: Add integer overflow checks.
13971 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
13972 (IN_INT_RANGE): New macros.
13973 (ccl_driver): Use them to check for integer overflow when
13974 decoding a CCL program. Many of the new checks are whether XINT (x)
13975 fits in int; it doesn't always, on 64-bit hosts. The new version
13976 doesn't catch all possible integer overflows, but it's an
13977 improvement. (Bug#8719)
13979 * alloc.c (make_event_array): Use XINT, not XUINT.
13980 There's no need for unsigned here.
13982 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
13983 This follows up to the 2011-05-06 change that substituted uintptr_t
13984 for EMACS_INT. This case wasn't caught back then.
13986 Rework Fformat to avoid integer overflow issues.
13987 * editfns.c: Include <float.h> unconditionally, as it's everywhere
13988 now (part of C89). Include <verify.h>.
13989 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
13990 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
13991 (Fformat): Avoid the prepass trying to compute sizes; it was only
13992 approximate and thus did not catch overflow reliably. Instead, walk
13993 through the format just once, formatting and computing sizes as we go,
13994 checking for integer overflow at every step, and allocating a larger
13995 buffer as needed. Keep track separately whether the format is
13996 multibyte. Keep only the most-recently calculated precision, rather
13997 than them all. Record whether each argument has been converted to
13998 string. Use EMACS_INT, not int, for byte and char and arg counts.
13999 Support field widths and precisions larger than INT_MAX. Avoid
14000 sprintf's undefined behavior with conversion specifications such as %#d
14001 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
14002 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
14003 formatting out-of-range floating point numbers with int
14004 formats. (Bug#8668)
14006 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
14008 * data.c: Avoid integer truncation in expressions involving floats.
14009 * data.c: Include <intprops.h>.
14010 (arith_driver): When there's an integer overflow in an expression
14011 involving floating point, convert the integers to floating point
14012 so that the resulting value does not suffer from catastrophic
14013 integer truncation. For example, on a 64-bit host (* 4
14014 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14015 Do not rely on undefined behavior after integer overflow.
14017 merge count_size_as_multibyte, parse_str_to_multibyte
14018 * character.c, character.h (count_size_as_multibyte):
14019 Rename from parse_str_to_multibyte; all uses changed.
14020 Check for integer overflow.
14021 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14022 since it's now a duplicate of the other. This is more of
14023 a character than a buffer op, so better that it's in character.c.
14024 * fns.c, print.c: Adjust to above changes.
14026 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14028 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14030 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14032 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14033 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14034 (x_clipboard_manager_save): Now static.
14035 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14037 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14038 (crypto_hash_function): Now static.
14039 Fix pointer signedness problems. Avoid unnecessary initializations.
14041 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14043 * termhooks.h (Vselection_alist): Make it terminal-local.
14045 * terminal.c (create_terminal): Initialize it.
14047 * xselect.c: Support for clipboard managers.
14048 (Vselection_alist): Move to termhooks.h as terminal-local var.
14049 (LOCAL_SELECTION): New macro.
14050 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14051 (symbol_to_x_atom): Remove gratuitous arg.
14052 (x_handle_selection_request, lisp_data_to_selection_data)
14053 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14054 (x_own_selection, x_get_local_selection, x_convert_selection):
14055 New arg, specifying work frame. Use terminal-local Vselection_alist.
14056 (some_frame_on_display): Delete unused function.
14057 (Fx_own_selection_internal, Fx_get_selection_internal)
14058 (Fx_disown_selection_internal, Fx_selection_owner_p)
14059 (Fx_selection_exists_p): New optional frame arg.
14060 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14061 (x_handle_selection_clear): Don't treat other terminals with the
14062 same keyboard specially. Use the terminal-local Vselection_alist.
14063 (x_clear_frame_selections): Use Frun_hook_with_args.
14065 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14067 * xterm.h: Add support for those atoms.
14069 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14071 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14072 (converted_selections, conversion_fail_tag): New global variables.
14073 (x_selection_request_lisp_error): Free the above.
14074 (x_get_local_selection): Remove unnecessary code.
14075 (x_reply_selection_request): Args changed; handle arbitrary array
14076 of converted selections stored in converted_selections.
14077 Separate the XChangeProperty and SelectionNotify steps.
14078 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14079 (x_convert_selection): New function.
14080 (x_handle_selection_event): Simplify.
14081 (x_get_foreign_selection): Don't ignore incoming requests while
14082 waiting for an answer; this will fail when we implement
14083 SAVE_TARGETS, and seems unnecessary anyway.
14084 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14085 (Vx_sent_selection_functions): Doc fix.
14087 2011-05-26 Leo Liu <sdl.web@gmail.com>
14089 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14091 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14093 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14095 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14096 for fringe update if it has periodic bitmap.
14097 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14098 and fringe_bitmap_periodic_p.
14100 * fringe.c (get_fringe_bitmap_data): New function.
14101 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14102 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14103 row. Mark glyph row for fringe update if periodicity changed.
14105 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14106 for fringe update unless it has periodic bitmap.
14108 2011-05-25 Kenichi Handa <handa@m17n.org>
14110 * xdisp.c (get_next_display_element): Set correct it->face_id for
14111 a static composition.
14113 2011-05-24 Leo Liu <sdl.web@gmail.com>
14116 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
14118 * fns.c (crypto_hash_function, Fsha1): New function.
14119 (Fmd5): Use crypto_hash_function.
14120 (syms_of_fns): Add Ssha1.
14122 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14124 * gnutls.c: Remove unused macros.
14125 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14126 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14127 Remove macros that are defined and never used.
14128 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14130 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14132 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14133 (Fx_get_selection_internal): Minor cleanup.
14134 (Fx_own_selection_internal): Rename arguments for consistency with
14137 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14139 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
14141 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14143 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
14145 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14147 * dispnew.c (scrolling_window): Don't exclude the case that the
14148 last enabled row in the desired matrix touches the bottom boundary.
14150 2011-05-21 Glenn Morris <rgm@gnu.org>
14152 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
14153 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
14154 and add some more files.
14156 2011-05-20 Eli Zaretskii <eliz@gnu.org>
14158 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
14159 report_file_error introduced by the change from 2011-05-07.
14161 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14163 * systime.h (Time): Define only if emacs is defined.
14164 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14165 where the include path doesn't have X11/X.h by default. See
14166 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14168 2011-05-20 Kenichi Handa <handa@m17n.org>
14170 * composite.c (find_automatic_composition): Fix previous change.
14172 2011-05-20 Glenn Morris <rgm@gnu.org>
14174 * lisp.mk: New file, split from Makefile.in.
14175 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14176 (shortlisp): Remove.
14177 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14179 2011-05-19 Glenn Morris <rgm@gnu.org>
14181 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14182 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14183 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14184 (lisp): Set the order to that of loadup.el.
14185 (shortlisp): Make it a copy of $lisp.
14186 (SOME_MACHINE_LISP): Remove.
14187 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14188 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14190 2011-05-18 Kenichi Handa <handa@m17n.org>
14192 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14193 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14194 (find_automatic_composition): Mostly rewrite for efficiency.
14196 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14198 * makefile.w32-in: Update dependencies.
14200 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14202 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14203 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14205 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14207 Fix some integer overflow issues, such as string length overflow.
14209 * insdel.c (count_size_as_multibyte): Check for string overflow.
14211 * character.c (lisp_string_width): Check for string overflow.
14212 Use EMACS_INT, not int, for string indexes and lengths; in
14213 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14214 the resulting string length overflows an EMACS_INT; instead,
14215 report a string overflow if no precision given. When checking for
14216 precision exhaustion, use a check that cannot possibly have
14217 integer overflow. (Bug#8675)
14218 * character.h (lisp_string_width): Adjust to new signature.
14220 * alloc.c (string_overflow): New function.
14221 (Fmake_string): Use it. This doesn't change behavior, but saves
14222 a few bytes and will simplify future changes.
14223 * character.c (string_escape_byte8): Likewise.
14224 * lisp.h (string_overflow): New decl.
14226 Fixups, following up to the user-interface timestamp change.
14227 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14228 for UI timestamps, instead of unsigned long.
14229 * msdos.c (mouse_get_pos): Likewise.
14230 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14231 * w32gui.h (Time): Define by including "systime.h" rather than by
14232 declaring it ourselves. (Bug#8664)
14234 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14235 * image.c (clear_image_cache): Likewise.
14237 * term.c (term_mouse_position): Don't assume time_t wraparound.
14239 Be more systematic about user-interface timestamps.
14240 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14241 and sometimes 'EMACS_UINT', to represent these timestamps.
14242 This change causes it to use 'Time' uniformly, as that's what X uses.
14243 This makes the code easier to follow, and makes it easier to catch
14244 integer overflow bugs such as Bug#8664.
14245 * frame.c (Fmouse_position, Fmouse_pixel_position):
14246 Use Time, not unsigned long, for user-interface timestamps.
14247 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14248 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14249 * keyboard.h (last_event_timestamp): Likewise.
14250 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14251 * menu.h (xmenu_show): Likewise.
14252 * term.c (term_mouse_position): Likewise.
14253 * termhooks.h (struct input_event.timestamp): Likewise.
14254 (struct terminal.mouse_position_hook): Likewise.
14255 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14256 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14257 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14258 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14259 what it was before.
14260 * menu.h, termhooks.h: Include "systime.h", for Time.
14262 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14263 Don't assume that the difference between two unsigned long values
14264 can fit into an integer. At this point, we know button_down_time
14265 <= event->timestamp, so the difference must be nonnegative, so
14266 there's no need to cast the result if double-click-time is
14267 nonnegative, as it should be; check that it's nonnegative, just in
14268 case. This bug is triggered when events are more than 2**31 ms
14269 apart (about 25 days). (Bug#8664)
14271 * xselect.c (last_event_timestamp): Remove duplicate decl.
14272 (x_own_selection): Remove needless cast to unsigned long.
14274 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14275 that always fit in int. Use a sentinel instead of a counter, to
14276 avoid a temp and to allay GCC's concerns about possible int overflow.
14277 * frame.h (struct frame): Use int for menu_bar_items_used
14278 instead of EMACS_INT, since it always fits in int.
14280 * menu.c (grow_menu_items): Check for int overflow.
14282 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14284 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14285 Before, the code was not consistent. These values cannot exceed
14286 2**31 - 1 so there's no need to make them unsigned.
14287 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14288 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14289 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14291 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14293 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14294 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14295 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14296 presumably because the widths might not match.
14298 * window.c (size_window): Avoid needless test at loop start.
14300 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14302 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14304 2011-05-12 Drew Adams <drew.adams@oracle.com>
14306 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14308 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14310 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14311 `width' to `bar_area_x' and `bar_area_width', respectively.
14312 (x_scroll_run): Take account of fringe background extension.
14314 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14315 Rename local vars `left' and `width' to `bar_area_x' and
14316 `bar_area_width', respectively.
14317 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14318 background extension.
14320 2011-05-10 Jim Meyering <meyering@redhat.com>
14322 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14324 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14326 * image.c (Finit_image_library): Return t for built-in image types,
14327 like pbm and xbm. (Bug#8640)
14329 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14331 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14333 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14335 * w32console.c (Fset_screen_color): Doc fix.
14336 (Fget_screen_color): New function.
14337 (syms_of_ntterm): Defsubr it.
14339 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14340 unlink the temporary file if Fcall_process didn't create it in the
14342 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14343 child process will be redirected to a file specified with `:file'.
14344 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14345 cue to call_process_cleanup not to close that handle.
14347 2011-05-07 Ben Key <bkey76@gmail.com>
14349 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14350 one of two shell specific rules, either bootstrap-temacs-CMD or
14351 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14352 to the previous implementation of the bootstrap-temacs rule.
14353 The bootstrap-temacs-CMD rule is similar to the previous
14354 implementation of the bootstrap-temacs rule except that it
14355 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14358 These changes, along with some changes to nt/configure.bat,
14359 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14360 earlier fix to add support for --cflags and --ldflags options
14361 that include quotes so that it works whether make uses cmd or
14364 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14366 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14367 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14369 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14370 a string. Handle both cases.
14371 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14372 (Fdbus_register_method): Use Qinvalid_function.
14374 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14376 * makefile.w32-in: Update dependencies.
14377 (LISP_H): Add inttypes.h and stdin.h.
14378 (PROCESS_H): Add unistd.h.
14380 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14382 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14383 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14385 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14387 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14389 * term.c (vfatal): Remove stray call to va_end.
14390 It's not needed and the C Standard doesn't allow it here anyway.
14392 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14393 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14395 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14398 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14400 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14402 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14404 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14406 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14408 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14409 * charset.c (Fdefine_charset_internal): Don't initialize
14410 charset.code_space[15]. The value was garbage, on hosts with
14411 32-bit int (Bug#8600).
14413 * lread.c (read_integer): Be more consistent with string-to-number.
14414 Use string_to_number to do the actual conversion; this avoids
14415 rounding errors and fixes some other screwups. Without this fix,
14416 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14417 (digit_to_number): Move earlier, for benefit of read_integer.
14418 Return -1 if the digit is out of range for the base, -2 if it is
14419 not a digit in any supported base. (Bug#8602)
14421 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14423 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14424 to match comment at start of function. This also removes a
14425 GCC warning about overflow in a 32+64-bit port.
14427 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14429 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14430 Reported by Stefan Monnier in
14431 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14432 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14433 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14435 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14436 (EMACS_UINTPTR): Likewise, with uintptr_t.
14438 * lisp.h: Prefer 64-bit EMACS_INT if available.
14439 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14440 on 32-bit hosts that have 64-bit int, so that they can access
14442 However, temporarily disable this change unless the temporary
14443 symbol WIDE_EMACS_INT is defined.
14445 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14447 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14448 This removes an assumption that EMACS_INT and long are the same
14449 width as pointers. The assumption is true for Emacs porting targets
14450 now, but we want to make other targets possible.
14451 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14452 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14453 In the rest of the code, change types of integers that hold casted
14454 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14455 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14456 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14457 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14458 No need to cast type when ORing.
14459 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14460 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14461 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14462 assume EMACS_INT is the same width as char *.
14463 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14464 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14465 Remove no-longer-needed casts.
14466 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14467 (xg_tool_bar_help_callback, xg_make_tool_item):
14468 Use EMACS_INTPTR to hold an integer
14469 that will be cast to void *; this can avoid a GCC warning
14470 if EMACS_INT is not the same width as void *.
14471 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14472 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14473 (current_message_1, set_message_1):
14474 Use a local to convert to proper width without a cast.
14475 * xmenu.c (dialog_selection_callback): Likewise.
14477 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14478 Also, don't assume VALBITS / RAND_BITS is less than 5,
14479 and don't rely on undefined behavior when shifting a 1 left into
14481 * lisp.h (get_random): Change signature to match.
14483 * lread.c (hash_string): Use size_t, not int, for hash computation.
14484 Normally we prefer signed values; but hashing is special, because
14485 it's better to use unsigned division on hash table sizes so that
14486 the remainder is nonnegative. Also, size_t is the natural width
14487 for hashing into memory. The previous code used 'int', which doesn't
14488 retain enough info to hash well into very large tables.
14489 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14491 * dbusbind.c: Don't possibly lose pointer info when converting.
14492 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14493 Use XPNTR rather than XHASH, so that the high-order bits of
14494 the pointer aren't lost when converting through void *.
14496 * eval.c (Fautoload): Don't double-shift a pointer.
14498 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14500 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14502 * gnutls.c (DEF_GNUTLS_FN):
14503 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14505 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14507 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14510 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14512 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14513 New version that can reserve upto 2GB of heap space.
14515 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14517 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14519 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14521 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14522 `gnutls_certificate_set_x509_key_file'.
14524 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
14526 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
14527 Update dependencies.
14529 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14531 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14532 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14533 Remove unused parameter `fildes'.
14534 * process.c (read_process_output, send_process): Don't pass it.
14536 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14538 Fix previous change: the library cache is defined in w32.c.
14539 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14540 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14542 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14544 Implement dynamic loading of GnuTLS on Windows.
14546 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14547 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14548 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14551 * gnutls.c (Qgnutls_dll): Define.
14552 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
14553 (gnutls_*): Declare function pointers.
14554 (init_gnutls_functions): New function to initialize function pointers.

14557 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14558 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
14559 (emacs_gnutls_write, emacs_gnutls_read)
14560 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14561 (Fgnutls_available_p): New function.
14562 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

14572 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
14574 * w32.c (QCloaded_from, Vlibrary_cache): Define.
14575 (w32_delayed_load): Move from image.c. When loading a library, record
14576 its filename in the :loaded-from property of the library id.
14577 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
14578 Initialize and staticpro them.
14579 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
14581 * process.c: Include lisp.h before w32.h, not after.
14582 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
14583 instead of gnutls_record_check_pending.
14585 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
14587 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
14589 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
14590 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
14593 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
14595 * xterm.c (x_set_frame_alpha): Do not set property on anything
14596 else than FRAME_X_OUTER_WINDOW (Bug#8608).
14598 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14600 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
14602 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14604 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

14618 * sysdep.c (wait_for_termination_1): Make static.
14619 (wait_for_termination, interruptible_wait_for_termination):
14620 Move after wait_for_termination_1.
14622 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
14624 * sysdep.c (interruptible_wait_for_termination): New function
14625 which is like wait_for_termination, but allows keyboard
14628 * callproc.c (Fcall_process): Add (:file "file") as an option for
14630 (Fcall_process_region): Ditto.
14632 2011-04-30 Eli Zaretskii <eliz@gnu.org>
14634 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
14635 rather than `XVECTOR (FOO)->size'.
14637 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
14638 inttypes.h, as a gnulib replacement is used if it not available in
14641 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14643 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
14644 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
14645 of MOST_POSITIVE_FIXNUM. (Bug#8528)
14647 * coding.c (coding_alloc_by_realloc): Error out if destination
14648 will grow beyond MOST_POSITIVE_FIXNUM.
14649 (decode_coding_emacs_mule): Abort if there isn't enough place in
14650 charbuf for the composition carryover bytes. Reserve an extra

14659 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
14660 %llo or %llx format is passed. (Bug#8545)
14662 * window.c (window_scroll_line_based): Use a marker instead of
14663 simple variables to record original value of point. (Bug#7952)
14665 * doprnt.c (doprnt): Fix the case where a multibyte sequence
14666 produced by %s or %c overflows available buffer space. (Bug#8545)
14668 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
14670 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
14671 (SIZE_MAX): Move defn after all includes, as they might #define it.
14673 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14675 * w32.c (init_environment): Warn about defaulting HOME to C:\.

14695 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14697 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
14699 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
14701 * makefile.w32-in: Update dependencies.
14703 2011-04-27 Eli Zaretskii <eliz@gnu.org>
14705 Improve `doprnt' and its usage. (Bug#8545)
14706 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
14707 `format_end'. Remove support for %l as a conversion specifier.
14708 Don't use xrealloc. Improve diagnostics when the %l size modifier
14709 is used. Update the commentary.
14711 * eval.c (verror): Simplify calculation of size_t.
14713 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
14716 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
14718 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
14721 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14723 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
14724 This makes this file independent of the recent pseudovector change.
14726 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
14728 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
14730 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
14731 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
14732 Remove unused local.
14733 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
14735 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
14736 GCC 4.6.0 optimizes based on type-based alias analysis.
14737 For example, if b is of type struct buffer * and v of type struct
14738 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
14739 != &v->size, and therefore "v->size = 1; b->size = 2; return
14740 v->size;" must therefore return 1. This assumption is incorrect
14741 for Emacs, since it type-puns struct Lisp_Vector * with many other
14742 types. To fix this problem, this patch adds a new type struct
14743 vectorlike_header that documents the constraints on layout of vectors
14744 and pseudovectors, and helps optimizing compilers not get fooled
14745 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
14746 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
14747 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
14749 (XSETPVECTYPE): Rewrite in terms of new macro.
14750 (XSETPVECTYPESIZE): New macro, specifying both type and size.
14751 This is a bit clearer, and further avoids the possibility of
14752 undesirable aliasing.
14753 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
14754 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
14755 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
14756 since Lisp_Subr is a special case (no "next" field).
14757 (ASIZE): Now uses header.size rather than size.
14758 All previous uses of XVECTOR (foo)->size replaced to use this macro,
14759 to avoid the hassle of writing XVECTOR (foo)->header.size.
14760 (struct vectorlike_header): New type.
14761 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
14762 object, to help avoid aliasing.
14763 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
14764 (SUBRP): Likewise, since Lisp_Subr is a special case.
14765 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
14766 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
14767 (struct Lisp_Hash_Table): Combine first two members into a single
14768 struct vectorlike_header member. All uses of "size" and "next" members
14769 changed to be "header.size" and "header.next".
14770 * buffer.h (struct buffer): Likewise.
14771 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
14772 * frame.h (struct frame): Likewise.
14773 * process.h (struct Lisp_Process): Likewise.
14774 * termhooks.h (struct terminal): Likewise.
14775 * window.c (struct save_window_data, struct saved_window): Likewise.
14776 * window.h (struct window): Likewise.
14777 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
14778 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
14779 * buffer.c (init_buffer_once): Likewise.
14780 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
14782 * process.c (Fformat_network_address): Use local var for size,
14785 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
14787 Make the Lisp reader and string-to-float more consistent (Bug#8525)
14788 * data.c (atof): Remove decl; no longer used or needed.
14789 (digit_to_number): Move to lread.c.
14790 (Fstring_to_number): Use new string_to_number function, to be
14791 consistent with how the Lisp reader treats infinities and NaNs.
14792 Do not assume that floating-point numbers represent EMACS_INT
14793 without losing information; this is not true on most 64-bit hosts.
14794 Avoid double-rounding errors, by insisting on integers when
14795 parsing non-base-10 numbers, as the documentation specifies.
14796 * lisp.h (string_to_number): New decl, replacing ...
14797 (isfloat_string): Remove.
14798 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
14799 (read1): Do not accept +. and -. as integers; this
14800 appears to have been a coding error. Similarly, do not accept
14801 strings like +-1e0 as floating point numbers. Do not report
14802 overflow for integer overflows unless the base is not 10 which
14803 means we have no simple and reliable way to continue.
14804 Break out the floating-point parsing into a new
14805 function string_to_number, so that Fstring_to_number parses
14806 floating point numbers consistently with the Lisp reader.
14807 (digit_to_number): Move here from data.c. Make it static inline.
14808 (E_CHAR, EXP_INT): Remove, replacing with ...
14809 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
14810 (string_to_number): New function, replacing isfloat_string.
14811 This function checks for valid syntax and produces the resulting
14812 Lisp float number too. Rework it so that string-to-number
14813 no longer mishandles examples like "1.0e+". Use strtoumax,
14814 so that overflow for non-base-10 numbers is reported only when
14815 there's no portable and simple way to convert to floating point.
14817 * textprop.c (set_text_properties_1): Rewrite for clarity,
14818 and to avoid GCC warning about integer overflow.
14820 * intervals.h (struct interval): Use EMACS_INT for members
14821 where EMACS_UINT might cause problems. See
14822 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
14823 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
14824 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
14826 (offset_intervals): Tell GCC not to worry about length overflow
14827 when negating a negative length.
14829 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
14830 (overrun_check_free): Likewise.
14832 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
14833 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
14836 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14837 (gnutls_make_error): Rename local to avoid shadowing.
14838 (gnutls_emacs_global_deinit): ifdef out; not used.
14839 (Fgnutls_boot): Use const for pointer to readonly storage.
14840 Comment out unused local. Fix pointer signedness problems.
14842 * lread.c (openp): Don't stuff size_t into an 'int'.
14843 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
14844 about possible signed overflow.
14846 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14847 (GDK_KEY_g): Don't define if already defined.
14848 (xg_prepare_tooltip): Avoid pointer signedness problem.
14849 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
14851 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
14852 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
14854 * xfns.c (Fx_window_property): Simplify a bit,
14855 to make a bit faster and to avoid GCC 4.6.0 warning.
14856 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
14858 * fns.c (internal_equal): Don't assume size_t fits in int.
14860 * alloc.c (compact_small_strings): Tighten assertion a little.
14862 Replace pEd with more-general pI, and fix some printf arg casts.
14863 * lisp.h (pI): New macro, generalizing old pEd macro to other
14864 conversion specifiers. For example, use "...%"pI"d..." rather
14865 than "...%"pEd"...".
14866 (pEd): Remove. All uses replaced with similar uses of pI.
14867 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
14868 * alloc.c (check_pure_size): Don't overflow by converting size to int.
14869 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
14870 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
14871 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
14872 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
14873 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
14875 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
14876 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
14877 * print.c (safe_debug_print, print_object): Likewise.
14878 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
14880 Use pI instead of if-then-else-abort. Use %p to avoid casts,
14881 avoiding the 0 flag, which is not portable.
14882 * process.c (Fmake_network_process): Use pI to avoid cast.
14883 * region-cache.c (pp_cache): Likewise.
14884 * xdisp.c (decode_mode_spec): Likewise.
14885 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
14886 behavior on 64-bit hosts with printf arg.
14887 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
14888 (x_stop_queuing_selection_requests): Likewise.
14889 (x_get_window_property): Don't truncate byte count to an 'int'
14892 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
14893 here, since it parses constructs like leading '-' and spaces,
14894 which are not wanted; and it overflows with large numbers.
14895 Instead, simply match F[0-9]+, which is what is wanted anyway.
14897 * alloc.c: Remove unportable assumptions about struct layout.
14898 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
14899 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
14900 (allocate_vectorlike, make_pure_vector): Use the new macros,
14901 plus offsetof, to remove unportable assumptions about struct layout.
14902 These assumptions hold on all porting targets that I know of, but
14903 they are not guaranteed, they're easy to remove, and removing them
14904 makes further changes easier.
14906 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
14907 This doesn't fix a bug but makes the code clearer.
14908 (string_overrun_cookie): Now const. Use initializers that
14909 don't formally overflow signed char, to avoid warnings.
14910 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
14911 can cause Emacs to crash when string overrun checking is enabled.
14912 (allocate_buffer): Don't assume sizeof (struct buffer) is a
14913 multiple of sizeof (EMACS_INT); it need not be, if
14914 alignof(EMACS_INT) < sizeof (EMACS_INT).
14915 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
14917 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

14924 supposed to be handshaking. (Bug#8556)
14925 Reported by Paul Eggert <eggert@cs.ucla.edu>.

14938 (check_string_free_list): Convert to standard C.
14940 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
14942 * w32.c (emacs_gnutls_push): Fix typo.
14944 2011-04-25 Eli Zaretskii <eliz@gnu.org>
14946 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
14947 "cast to pointer from integer of different size".
14949 Improve doprnt and its use in verror. (Bug#8545)
14950 * doprnt.c (doprnt): Document the set of format control sequences
14951 supported by the function. Use SAFE_ALLOCA instead of always
14954 * eval.c (verror): Don't limit the buffer size at size_max-1, that
14955 is one byte too soon. Don't use xrealloc; instead xfree and
14958 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
14960 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
14963 * gnutls.c: Renamed global_initialized to
14964 gnutls_global_initialized. Added internals for the
14965 :verify-hostname-error, :verify-error, and :verify-flags
14966 parameters of `gnutls-boot' and documented those parameters in the
14967 docstring. Start callback support.
14968 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
14969 unless a fatal error occurred. Call gnutls_alert_send_appropriate
14970 on error. Return error code.

15030 changes in globals.h immediately force recompilation.
15031 (TAGS): Depend on $(CURDIR)/m/intel386.h and
15032 $(CURDIR)/s/ms-w32.h.

15042 * doprnt.c: Include limits.h.
15043 (SIZE_MAX): New macro.
15044 (doprnt): Return a size_t value. 2nd arg is now size_t.
15045 Many local variables are now size_t instead of int or unsigned.
15046 Improve overflow protection. Support `l' modifier for integer
15047 conversions. Support %l conversion. Don't assume an EMACS_INT
15048 argument for integer conversions and for %c.
15050 * lisp.h (doprnt): Restore prototype.
15052 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
15053 $(SRC)/character.h.
15055 * Makefile.in (base_obj): Add back doprnt.o.
15057 * deps.mk (doprnt.o): Add back prerequisites.
15058 (callint.o): Depend on character.h.
15060 * eval.c (internal_lisp_condition_case): Include the handler
15061 representation in the error message.
15062 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
15063 when breaking from the loop.

15067 * callint.c (Fcall_interactively): When displaying error message
15068 about invalid control letter, pass the character's codepoint, not
15069 a pointer to its multibyte form. Improve display of the character
15070 in octal and display also its hex code.
15072 * character.c (char_string): Use %x to display the (unsigned)
15073 codepoint of an invalid character, to avoid displaying a bogus
15076 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15077 `error', not SYMBOL_NAME itself.
15079 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
15080 character arguments to `error'.
15082 * charset.c (check_iso_charset_parameter): Fix incorrect argument
15083 to `error' in error message about FINAL_CHAR argument. Make sure
15084 FINAL_CHAR is a character, and use %c when it is passed as
15085 argument to `error'.

15149 Define only if needed.
15151 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
15152 by pacifying GCC about it. Maybe it's time to retire it?
15153 * xfaces.c (USG, __TIMEVAL__): Likewise.
15155 * dispextern.h (struct redisplay_interface): Rename param
15156 to avoid shadowing.
15157 * termhooks.h (struct terminal): Likewise.
15158 * xterm.c (xembed_send_message): Likewise.
15160 * insdel.c (make_gap_smaller): Define only if
15161 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
15163 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
15166 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
15167 so that we aren't warned about unused symbols.
15169 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
15171 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
15173 * xfns.c (x_real_positions): Mark locals as initialized.
15175 * xmenu.c (xmenu_show): Don't use uninitialized vars.

15178 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
15179 (x_dispatch_event): Declare static if USE_GTK, and
15180 define if USE_GTK || USE_X_TOOLKIT.
15181 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
15182 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
15183 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
15184 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
15186 * xmenu.c (menu_help_callback): Pointer type fixes.
15187 Use const pointers when pointing at readonly data. Avoid pointer

15203 * bitmaps: Change bitmaps from unsigned char back to the X11
15204 compatible char. Avoid the old compiler warnings about
15205 out-of-range initializers by using, for example, '\xab' rather
15208 * xgselect.c (xgselect_initialize): Check vs interface

15646 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
15648 alloc.c: Import and export fewer symbols, and remove unused items.
15649 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
15651 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
15652 it's not optimized away by whole-program optimization.
15653 (message_enable_multibyte, free_misc): Remove.
15654 (catchlist, handlerlist, mark_backtrace):
15655 Declare only if BYTE_MARK_STACK.
15656 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
15657 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
15658 (message_enable_multibyte): Remove decl.
15659 (free_misc, interval_free_list, float_block, float_block_index):
15660 (n_float_blocks, float_free_list, cons_block, cons_block_index):
15661 (cons_free_list, last_marked_index):
15663 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
15664 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
15665 (mark_backtrace): Define only if BYTE_MARK_STACK.
15666 * xdisp.c (message_enable_multibyte): Now static.
15668 Declare Lisp_Object Q* variables to be 'static' if not exported.
15669 This makes it easier for human readers (and static analyzers)
15670 to see whether these variables are used from other modules.
15671 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
15672 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
15673 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
15674 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
15675 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
15676 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
15677 * xmenu.c, xselect.c:
15678 Declare Q* vars static if they are not used in other modules.
15679 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
15680 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
15681 Remove decls of unexported vars.
15682 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
15684 * lisp.h (DEFINE_FUNC): Make sname 'static'.
15686 Make Emacs functions such as Fatom 'static' by default.
15687 This makes it easier for human readers (and static analyzers)
15688 to see whether these functions can be called from other modules.
15689 DEFUN now defines a static function. To make the function external
15690 so that it can be used in other C modules, use the new macro DEFUE.
15691 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
15692 (Finit_image_library):
15693 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
15694 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
15695 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
15696 Remove decls, since these functions are now static.
15697 (Funintern, Fget_internal_run_time): New decls, since these functions
15698 were already external.
15700 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
15701 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
15702 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
15703 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
15704 * keyboard.c, keymap.c, lread.c:
15705 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
15706 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
15707 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
15708 Mark functions with DEFUE instead of DEFUN,
15709 if they are used in other modules.
15710 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
15711 decls for now-static functions.
15712 * buffer.h (Fdelete_overlay): Remove decl.
15713 * callproc.c (Fgetenv_internal): Mark as internal.
15714 * composite.c (Fremove_list_of_text_properties): Remove decl.

15718 * doc.c (Fdocumntation_property): New forward static decl.
15719 * eval.c (Ffetch_bytecode): New forward static decl.
15720 (Funintern): Remove extern decl; now in .h file where it belongs.
15721 * fileio.c (Fmake_symbolic_link): New forward static decl.
15722 * image.c (Finit_image_library): New forward static decl.
15723 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
15724 * intervals.h (Fprevious_property_change):
15725 (Fremove_list_of_text_properties): Remove decls.
15726 * keyboard.c (Fthis_command_keys): Remove decl.
15727 (Fcommand_execute): New forward static decl.
15728 * keymap.c (Flookup_key): New forward static decl.
15729 (Fcopy_keymap): Now static.
15730 * keymap.h (Flookup_key): Remove decl.
15731 * process.c (Fget_process): New forward static decl.
15732 (Fprocess_datagram_address): Mark as internal.

15743 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
15745 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
15748 2011-04-13 Eli Zaretskii <eliz@gnu.org>
15750 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
15751 when at ZV. (Bug#8487)
15753 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
15755 * charset.c (Fclear_charset_maps): Use xfree instead of free.
15757 * keyboard.c (parse_tool_bar_item): Likewise.
15758 * sound.c (sound_cleanup, alsa_close): Likewise.
15759 * termcap.c (tgetent): Likewise.
15760 * xfns.c (x_default_font_parameter): Likewise.
15761 * xsettings.c (read_and_apply_settings): Likewise.
15763 * alloc.c (overrun_check_malloc, overrun_check_realloc)
15764 (overrun_check_free): Protoize.
15766 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
15768 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
15769 since callers should never pass a negative size.
15770 Change the signature to match that of plain 'read' and 'write'; see
15771 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
15772 * lisp.h: Update prototypes of emacs_write and emacs_read.
15774 2011-04-11 Eli Zaretskii <eliz@gnu.org>
15776 * xdisp.c (redisplay_window): Don't try to determine the character
15777 position of the scroll margin if the window start point w->startp
15778 is outside the buffer's accessible region. (Bug#8468)
15780 2011-04-10 Eli Zaretskii <eliz@gnu.org>
15782 Fix write-region and its subroutines for buffers > 2GB.
15783 * fileio.c (a_write, e_write): Modify declaration of arguments and
15784 local variables to support buffers larger than 2GB.
15785 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
15787 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
15788 argument, local variables, and return value.
15790 * lisp.h: Update prototypes of emacs_write and emacs_read.
15792 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
15794 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
15796 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
15798 Fix more problems found by GCC 4.6.0's static checks.
15800 * xdisp.c (vmessage): Use a better test for character truncation.
15802 * charset.c (load_charset_map): <, not <=, for optimization,
15803 and to avoid potential problems with integer overflow.
15804 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
15805 * casetab.c (set_identity, shuffle): Likewise.
15806 * editfns.c (Fformat): Likewise.
15807 * syntax.c (skip_chars): Likewise.
15809 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
15810 This also lets GCC 4.6.0 generate slightly better loop code.
15812 * callint.c (Fcall_interactively): <, not <=, for optimization.
15813 (Fcall_interactively): Count the number of arguments produced,
15814 not the number of arguments given. This is simpler and lets GCC
15815 4.6.0 generate slightly better code.
15817 * ftfont.c: Distingish more carefully between FcChar8 and char.
15818 The previous code passed unsigned char * to a functions like
15819 strlen and xstrcasecmp that expect char *, which does not
15820 conform to the C standard.
15821 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
15822 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
15823 char * when the C standard requires it.
15825 * keyboard.c (read_char): Remove unused var.
15827 * eval.c: Port to Windows vsnprintf (Bug#8435).
15828 Include <limits.h>.
15829 (SIZE_MAX): Define if the headers do not.
15830 (verror): Do not give up if vsnprintf returns a negative count.
15831 Instead, grow the buffer. This ports to Windows vsnprintf, which
15832 does not conform to C99. Problem reported by Eli Zaretskii.
15833 Also, simplify the allocation scheme, by avoiding the need for
15834 calling realloc, and removing the ALLOCATED variable.
15836 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
15838 Remove invocations of doprnt, as Emacs now uses vsnprintf.
15839 But keep the doprint source code for now, as we might revamp it
15840 and use it again (Bug#8435).
15841 * lisp.h (doprnt): Remove.
15842 * Makefile.in (base_obj): Remove doprnt.o.
15843 * deps.mk (doprnt.o): Remove.
15845 error: Print 32- and 64-bit integers portably (Bug#8435).
15846 Without this change, on typical 64-bit hosts error ("...%d...", N)
15847 was used to print both 32- and 64-bit integers N, which relied on
15848 undefined behavior.
15849 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
15850 * lisp.h (error, verror): Mark as printf-like functions.
15851 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
15852 Report overflow in size calculations when allocating printf buffer.
15853 Do not truncate output string at its first null byte.
15854 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
15855 Truncate the output at a character boundary, since vsnprintf does not
15857 * charset.c (check_iso_charset_parameter): Convert internal
15858 character to string before calling 'error', since %c now has the
15860 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
15861 overflow when computing char to be passed to 'error'. Do not
15862 pass Lisp_Object to 'error'; pass the integer instead.
15863 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
15864 formatted with plain %d.
15866 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
15868 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
15870 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
15872 * xterm.c (x_catch_errors): Remove duplicate declaration.
15874 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
15876 * xdisp.c, lisp.h (message_nolog): Remove; unused.
15878 2011-04-10 Jim Meyering <meyering@redhat.com>
15880 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
15881 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
15882 return ssize_t not "int", and use size_t as the buffer length.
15883 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
15884 * gnutls.h: Update declarations.
15885 * process.c (read_process_output): Use ssize_t, to match.
15886 (send_process): Likewise.
15888 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15890 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
15892 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15894 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
15895 Use unsigned char, to match FcChar8 type definition.
15897 * xterm.c (handle_one_xevent):
15898 * xmenu.c (create_and_show_popup_menu):
15899 * xselect.c (x_decline_selection_request)
15900 (x_reply_selection_request): Avoid type-punned deref of X events.
15902 2011-04-09 Eli Zaretskii <eliz@gnu.org>
15904 Fix some uses of `int' instead of EMACS_INT.
15905 * search.c (string_match_1, fast_string_match)
15906 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
15907 (scan_buffer, find_next_newline_no_quit)
15908 (find_before_next_newline, search_command, Freplace_match)
15909 (Fmatch_data): Make some `int' variables be EMACS_INT.
15911 * xdisp.c (display_count_lines): 3rd argument and return value now
15912 EMACS_INT. All callers changed.
15913 (pint2hrstr): Last argument is now EMACS_INT.
15915 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
15916 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
15917 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
15918 (decode_coding_utf_16, decode_coding_emacs_mule)
15919 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
15920 (decode_coding_ccl, decode_coding_charset)
15921 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
15922 (decode_coding_iso_2022, decode_coding_emacs_mule)
15923 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
15924 <char_offset, last_offset>: Declare EMACS_INT.
15925 (encode_coding_utf_8, encode_coding_utf_16)
15926 (encode_coding_emacs_mule, encode_invocation_designation)
15927 (encode_designation_at_bol, encode_coding_iso_2022)
15928 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
15929 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
15931 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
15932 (encode_invocation_designation): Last argument P_NCHARS is now
15934 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
15935 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
15937 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
15940 * ccl.c (Fccl_execute_on_string): Declare some variables
15943 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
15945 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
15947 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
15949 * process.c (Fformat_network_address): Doc fix.
15951 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
15953 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
15955 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
15957 * keyboard.c (read_char): Call Lisp function help-form-show,
15958 instead of using internal_with_output_to_temp_buffer.
15959 (Qhelp_form_show): New var.
15960 (syms_of_keyboard): Use DEFSYM macro.
15962 * print.c (internal_with_output_to_temp_buffer): Function deleted.
15964 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
15966 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
15968 * process.c (Flist_processes): Remove to Lisp.
15969 (list_processes_1): Delete.
15971 2011-04-06 Eli Zaretskii <eliz@gnu.org>
15973 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
15975 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
15977 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
15979 Fix more problems found by GCC 4.6.0's static checks.
15981 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
15983 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
15985 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
15987 * xdisp.c (vmessage): Mark as a printf-like function.
15989 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
15991 * sound.c (sound_warning): Don't crash if arg contains a printf format.
15993 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
15994 printf-like functions.
15995 (tiff_load): Add casts to remove these marks before passing them
15996 to system-supplied API.
15998 * eval.c (Fsignal): Remove excess argument to 'fatal'.
16000 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
16001 This avoids several warnings with gcc -Wstrict-overflow.
16002 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
16003 directly, rather than having caller test rule sign. This avoids
16004 some unnecessary tests.
16005 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
16006 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
16007 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
16009 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16010 (xfont_open): Avoid unnecessary tests.
16012 * composite.c (composition_gstring_put_cache): Use unsigned integer.
16014 * composite.h, composite.c (composition_gstring_put_cache):
16015 Use EMACS_INT, not int, for length.
16017 * composite.h (COMPOSITION_DECODE_REFS): New macro,
16018 breaking out part of COMPOSITION_DECODE_RULE.
16019 (COMPOSITION_DECODE_RULE): Use it.
16020 * composite.c (get_composition_id): Remove unused local vars,
16021 by using the new macro.
16023 * textprop.c (set_text_properties_1): Change while to do-while,
16024 since the condition is always true at first.
16026 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16027 (interval_deletion_adjustment): Return unsigned value.
16030 * process.c (list_processes_1, create_pty, read_process_output):
16031 (exec_sentinel): Remove vars that were set but not used.
16032 (create_pty): Remove unnecessary "volatile"s.
16033 (Fnetwork_interface_info): Avoid possibility of int overflow.
16034 (read_process_output): Do adaptive read buffering even if carryover.
16035 (read_process_output): Simplify nbytes computation if buffered.
16037 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
16039 * syntax.c (scan_words): Remove var that was set but not used.
16040 (update_syntax_table): Use unsigned instead of int.
16042 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
16043 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
16044 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
16046 * print.c (print_error_message): Avoid int overflow.
16048 * font.c (font_list_entities): Redo for clarity,
16049 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
16051 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
16052 (font_score): Avoid potential overflow in diff calculation.
16054 * fns.c (substring_both): Remove var that is set but not used.
16055 (sxhash): Redo loop for clarity and to avoid wraparound warning.
16057 * eval.c (funcall_lambda): Rename local to avoid shadowing.
16059 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
16060 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
16061 can always succeed if overflow has undefined behavior.
16063 * search.c (boyer_moore, wordify): Remove vars set but not used.
16064 (wordify): Omit three unnecessary tests.
16066 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
16067 All callers changed. This avoids the need for an unused var.
16069 * casefiddle.c (casify_region): Remove var that is set but not used.
16071 * dired.c (file_name_completion): Remove var that is set but not used.
16073 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
16075 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16076 (Finsert_file_contents): Remove unnecessary code checking fd.
16078 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
16079 Check for integer overflow on size calculations.
16081 * buffer.c (Fprevious_overlay_change): Remove var that is set
16084 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16085 Remove vars that are set but not used.
16086 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16087 (timer_check_2): Mark vars as initialized.
16089 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16091 * image.c (lookup_image): Remove var that is set but not used.
16092 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16094 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16095 that are set but not used.
16097 * xfns.c (make_invisible_cursor): Don't return garbage
16098 if XCreateBitmapFromData fails (Bug#8410).
16100 * xselect.c (x_get_local_selection, x_handle_property_notify):
16101 Remove vars that are set but not used.
16103 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

16108 (scroll_bar_windows_size): Now size_t, not int.
16109 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16110 Check for overflow.
16112 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16113 (map_tty_color) [!defined MSDOS]: Likewise.
16115 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16117 * coding.c: Remove vars that are set but not used.
16118 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
16119 All callers changed.

16125 that is set but not used.
16127 * print.c (print_object): Remove var that is set but not used.
16129 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16130 The gnulib version avoids calling malloc in the usual case,
16131 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16132 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16133 * filelock.c (current_lock_owner): Likewise.
16134 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16135 * sysdep.c: Include allocator.h, careadlinkat.h.
16136 (emacs_no_realloc_allocator): New static constant.
16137 (emacs_readlink): New function.
16138 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16139 ../lib/careadlinkat.h.
16141 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
16143 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

16165 do not dereference NULL upon failed strdup
16166 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16167 (ns_get_family): Likewise.
16169 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16171 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16173 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16175 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16178 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16180 Add lexical binding.
16182 * window.c (Ftemp_output_buffer_show): New fun.

16191 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16193 (syms_of_lread): Declare `lexical-binding'.
16195 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16197 * keyboard.c (eval_dyn): New fun.
16198 (menu_item_eval_property): Use it.
16200 * image.c (parse_image_spec): Use Ffunctionp.
16202 * fns.c (concat, mapcar1): Accept byte-code-functions.
16204 * eval.c (Fsetq): Handle lexical vars.
16205 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16206 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16207 (FletX, Flet): Obey lexical binding.
16208 (Fcommandp): Handle closures.
16209 (Feval): New `lexical' arg.
16210 (eval_sub): New function extracted from Feval. Use it almost
16211 everywhere where Feval was used. Look up vars in lexical env.
16213 (Ffunctionp): Move from subr.el.
16214 (Ffuncall): Handle closures.
16215 (apply_lambda): Remove `eval_flags'.
16216 (funcall_lambda): Handle closures and new byte-code-functions.
16217 (Fspecial_variable_p): New function.
16218 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16219 but without exporting it to Lisp.
16221 * doc.c (Fdocumentation, store_function_docstring):
16222 * data.c (Finteractive_form): Handle closures.
16224 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16227 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16229 (exec_byte_code): New function extracted from Fbyte_code to handle new
16230 calling convention for byte-code-functions. Add new byte-codes.
16232 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
16234 * alloc.c (Fmake_symbol): Init new `declared_special' field.
16236 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16238 * xdisp.c (redisplay_internal): Fix prototype.
16240 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16242 * xdisp.c (SCROLL_LIMIT): New macro.
16243 (try_scrolling): Use it when setting scroll_limit.
16244 Limit scrolling to 100 screen lines.
16245 (redisplay_window): Even when falling back on "recentering",
16246 position point in the window according to scroll-conservatively,
16247 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16249 (try_scrolling): When point is above the window, allow searching
16250 as far as scroll_max, or one screenful, to compute vertical
16251 distance from PT to the scroll margin position. This prevents
16252 try_scrolling from unnecessarily failing when
16253 scroll-conservatively is set to a value slightly larger than the
16254 window height. Clean up the case of PT below the margin at bottom
16255 of window: scroll_max can no longer be INT_MAX. When aggressive
16256 scrolling is in use, don't let point enter the opposite scroll
16257 margin as result of the scroll.
16258 (syms_of_xdisp) <scroll-conservatively>: Document the
16259 threshold of 100 lines for never-recentering scrolling.

16266 (message_log_check_duplicate): Remove parameters `prev_bol' and
16267 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16268 (redisplay_internal): Remove parameter `preserve_echo_area',
16269 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16271 * indent.c (Fvertical_motion):
16272 * window.c (window_scroll_pixel_based, Frecenter):
16273 Don't pass `need_y_p' to `move_it_by_lines'.
16275 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16277 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16278 steal a few bits to be more compact.
16279 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16280 Remove unneeded casts.
16282 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16284 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16286 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16287 binding" message (bug#7967).
16289 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16291 Fix more problems found by GCC 4.6.0's static checks.
16293 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16294 Remove unused local var.
16296 * editfns.c (Fmessage_box): Remove unused local var.
16298 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16299 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16300 Omit unused local vars.
16301 * window.c (shrink_windows): Omit unused local var.
16302 * menu.c (digest_single_submenu): Omit unused local var.
16303 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16304 Omit unused local var.
16306 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16307 Don't assume string length fits in int.
16308 (keyremap_step, read_key_sequence): Use size_t for sizes.

16312 instead of alloca (Bug#8344).
16314 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16315 (Fbacktrace_frame): Don't assume nframes fits in int.
16317 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

16322 * term.c (produce_glyphless_glyph): Remove unnecessary test.
16324 * cm.c (calccost): Turn while-do into do-while, for clarity.
16326 * keyboard.c (syms_of_keyboard): Use the same style as later
16327 in this function when indexing through an array. This also
16328 works around GCC bug 48267.
16330 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16332 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16334 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16335 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16337 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16338 This avoids undefined behavior on integer overflow, and is a bit
16339 more convenient anyway since it is compared to a size_t variable.
16341 Variadic C functions now count arguments with size_t, not int.
16342 This avoids an unnecessary limitation on 64-bit machines, which
16343 caused (substring ...) to crash on large vectors (Bug#8344).

16353 * fns.c (concat): Likewise.
16354 * frame.c (x_set_frame_parameters): Likewise.
16355 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16356 0 if not found, not -1. All callers changed.
16358 * alloc.c (garbage_collect): Don't assume stack size fits in int.
16359 (stack_copy_size): Now size_t, not int.
16360 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
16362 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
16364 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
16365 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

16381 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
16382 don't set the hook to nil, but remove the offending function instead.
16383 (Qcommand_hook_internal): Remove, unused.
16384 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
16385 Vcommand_hook_internal.

16388 (funcall_nil, funcall_not): New functions.
16389 (run_hook_with_args): Call each function through a `funcall' argument.

16515 (w32_wnd_proc): Remove unused variable `isdead'.
16516 (unwind_create_frame): Use #if GLYPH_DEBUG, not #ifdef.
16517 (Fx_server_max_request_size): Remove unused variable `dpyinfo'.

16523 * w32term.c (x_draw_composite_glyph_string_foreground):
16524 Remove unused variable `width'.
16526 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
16528 * w32term.c (x_set_glyph_string_clipping):
16529 Don't pass uninitialized region to CombineRgn.
16531 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
16533 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.

16553 2011-03-23 Julien Danjou <julien@danjou.info>
16555 * term.c (Fsuspend_tty, Fresume_tty):
16556 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
16557 * window.c (temp_output_buffer_show):
16558 * insdel.c (signal_before_change):
16559 * frame.c (Fhandle_switch_frame):
16560 * fileio.c (Fdo_auto_save):

16563 * cmds.c (internal_self_insert):
16564 * callint.c (Fcall_interactively):
16565 * buffer.c (Fkill_all_local_variables):
16566 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
16568 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
16569 unconditionally since it does the check itself.
16571 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
16573 Fix more problems found by GCC 4.5.2's static checks.
16575 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16576 the first time through the loop, since we know p0 < p1 then.
16577 This also avoids a gcc -Wstrict-overflow warning.
16579 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16580 leading to a memory leak, possible in functions like
16581 load_charset_map_from_file that can allocate an unbounded number
16582 of objects (Bug#8318).
16584 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16585 that could (at least in theory) be that large.
16587 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16588 This is less likely to overflow, and avoids undefined behavior if
16589 overflow does occur. All callers changed. Use strtoul to scan
16590 for the unsigned long integer.
16591 (pint2hrstr): Simplify and tune code slightly.
16592 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
16594 * scroll.c (do_scrolling): Work around GCC bug 48228.
16595 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
16597 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
16598 This also avoids a warning with gcc -Wstrict-overflow.
16599 (validate_x_resource_name): Simplify count usage.
16600 This also avoids a warning with gcc -Wstrict-overflow.
16602 * fileio.c (Fcopy_file): Report error if fchown or fchmod
16605 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
16607 * process.c (Fmake_network_process): Use socklen_t, not int,
16608 where POSIX says socklen_t is required in portable programs.
16609 This fixes a porting bug on hosts like 64-bit HP-UX, where
16610 socklen_t is wider than int (Bug#8277).
16611 (Fmake_network_process, server_accept_connection):
16612 (wait_reading_process_output, read_process_output):
16615 * process.c: Rename or move locals to avoid shadowing.

16625 Make tparam.h and terminfo.c consistent.
16626 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
16627 Include tparam.h instead, since it declares them.
16628 * cm.h (PC): Remove extern decl; tparam.h now does this.
16629 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
16630 * terminfo.c: Include tparam.h, to check interfaces.
16631 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
16632 (tparam): Adjust signature to match interface in tparam.h;
16633 this removes some undefined behavior. Check that outstring and len
16634 are zero, which they always are with Emacs.
16635 * tparam.h (PC, BC, UP): New extern decls.
16637 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
16638 (xftfont_open): Rename locals to avoid shadowing.
16640 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
16641 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
16642 (OTF_TAG_SYM): Omit macro if not needed.

16650 * xml.c (make_dom): Now static.
16652 * composite.c (composition_compute_stop_pos): Rename local to
16654 (composition_reseat_it): Remove unused locals.
16655 (find_automatic_composition, composition_adjust_point): Likewise.
16656 (composition_update_it): Mark var as initialized.
16657 (find_automatic_composition): Mark vars as initialized,
16658 with a FIXME (Bug#8290).

16661 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
16662 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
16663 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
16664 (BUF_DEC_POS): Be more systematic about renaming local temporaries
16665 to avoid shadowing.
16667 * textprop.c (property_change_between_p): Remove; unused.
16669 * intervals.c (interval_start_pos): Now static.
16671 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

16674 Rename locals to avoid shadowing.
16676 * sound.c (wav_play, au_play, Fplay_sound_internal):
16677 Fix pointer signedness.
16678 (alsa_choose_format): Remove unused local var.
16679 (wav_play): Initialize a variable to 0, to prevent undefined
16680 behavior (Bug#8278).
16682 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
16684 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
16686 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
16687 clobbering (Bug#8298).
16688 * sysdep.c (sys_subshell): Likewise.
16689 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
16691 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
16692 This should get cleaned up, so that child_setup has the
16693 same signature on all platforms.
16695 * callproc.c (call_process_cleanup): Now static.
16696 (relocate_fd): Rename locals to avoid shadowing.
16698 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
16700 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
16701 not to be necessary, and produces flickering.
16703 2011-03-20 Glenn Morris <rgm@gnu.org>
16705 * config.in: Remove file.
16707 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
16709 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
16710 are now in src/globals.h.
16711 (syms_of_minibuf): Remove spurious & from previous change.
16713 2011-03-20 Leo Liu <sdl.web@gmail.com>
16715 * minibuf.c (completing-read-function): New variable.
16716 (completing-read-default): Rename from completing-read.
16717 (completing-read): Call completing-read-function.
16719 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16721 * xfaces.c (Fx_load_color_file):
16722 Read color file from absolute filename (bug#8250).
16724 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16726 * makefile.w32-in: Update dependencies.
16728 2011-03-17 Eli Zaretskii <eliz@gnu.org>
16730 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

16736 * process.c (make_serial_process_unwind, send_process_trap):
16737 (sigchld_handler): Now static.
16739 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
16740 That way, the code declares only the vars that it needs.
16741 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
16742 * s/cygwin.h (PTY_ITERATION): Likewise.
16743 * s/darwin.h (PTY_ITERATION): Likewise.

16747 * process.c (allocate_pty): Don't declare stb unless it's needed.
16749 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
16750 (CONSTANTLIM): Remove; unused.
16751 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
16752 Define only if needed.
16754 * unexelf.c (unexec): Name an expression,
16755 to avoid gcc -Wbad-function-cast warning.
16756 Use a different way to cause a compilation error if anyone uses
16757 n rather than nn, a way that does not involve shadowing.
16758 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
16760 * deps.mk (unexalpha.o): Remove; unused.
16762 New file unexec.h, the (simple) interface for unexec (Bug#8267).
16763 * unexec.h: New file.
16764 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
16765 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
16766 Depend on unexec.h.
16767 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
16768 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
16769 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
16770 Change as necessary to match prototype in unexec.h.
16772 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
16774 (back_comment, skip_chars): Mark vars as initialized.
16776 * character.h (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS):

16782 * print.c (Fredirect_debugging_output): Fix pointer signedess.
16784 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
16785 warning when compiling print.c.

16788 instead of using an uninitialized var.
16789 (font_sort_entities): Mark var as initialized.
16791 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
16793 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

16805 * floatfns.c (domain_error2): Define only if needed.
16806 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
16808 * alloc.c (mark_backtrace): Move decl from here ...
16809 * lisp.h: ... to here, so that it can be checked.
16811 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
16812 (Fdefvar): Rewrite so as not to use empty "else".

16817 * callint.c (quotify_arg, quotify_args): Now static.
16818 (Fcall_interactively): Rename locals to avoid shadowing.
16819 Use const pointer when appropriate.
16821 * lisp.h (get_system_name, get_operating_system_release):

16825 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
16826 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
16827 some of which prompt warnings from gcc -Wbad-function-cast.
16828 (Fformat_time_string, Fencode_time, Finsert_char):
16829 (Ftranslate_region_internal, Fformat):
16830 Rename or remove local vars to avoid shadowing.
16831 (Ftranslate_region_internal): Mark var as initialized.
16833 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
16836 * lisp.h (eassert): Check that the argument compiles, even if
16837 ENABLE_CHECKING is not defined.
16839 * data.c (Findirect_variable): Name an expression, to avoid
16840 gcc -Wbad-function-cast warning.

16848 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
16849 Rename locals to avoid shadowing.
16850 (mark_stack): Move local variables into the #ifdef region where
16852 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
16853 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
16855 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
16856 (GC_STRING_CHARS): Remove; not used.
16857 (Fmemory_limit): Cast sbrk's returned value to char *.
16859 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
16860 avoids undefined behavior in theory.
16862 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
16864 Use functions, not macros, for up- and down-casing (Bug#8254).
16865 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16866 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
16867 to use the following functions instead of these macros.
16868 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
16869 EMACS_INT, since callers assume the returned value fits in int.
16870 (upcase1): Likewise, for UPCASE_TABLE.
16871 (uppercasep, lowercasep, upcase): New static inline functions.
16872 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
16873 the race-condition problem in the old DOWNCASE.
16875 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
16876 Rename locals to avoid shadowing.
16877 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
16878 (regex_compile, re_search_2, re_match_2_internal):
16879 Remove unused local vars.
16880 (FREE_VAR): Rewrite so as not to use empty "else",
16881 which gcc can warn about.
16882 (regex_compile, re_match_2_internal): Mark locals as initialized.
16883 (RETALLOC_IF): Define only if needed.
16884 (WORDCHAR_P): Likewise. This one is never needed, but is used
16885 only in a comment talking about a compiler bug, so put inside
16886 the #if 0 of that comment.
16887 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
16888 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
16891 * search.c (boyer_moore): Rename locals to avoid shadowing.
16892 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
16893 (PREV_CHAR_BOUNDARY): Likewise.
16895 * search.c (simple_search): Remove unused var.
16897 * dired.c (compile_pattern): Move decl from here ...

16903 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
16905 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
16906 Rename locals to avoid shadowing.
16907 (Fvertical_motion): Mark locals as initialized.
16909 * casefiddle.c (casify_object, casify_region): Now static.
16910 (casify_region): Mark local as initialized.
16912 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
16914 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
16915 New macros, so that the caller can use some names other than
16916 gcpro1, gcpro2, etc.
16917 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
16919 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
16920 argument, for consistency with GCPRO2_VAR, etc: it is now the
16921 prefix of the variable, not the variable itself. All uses
16923 * dired.c (directory_files_internal, file_name_completion):
16924 Rename locals to avoid shadowing.
16926 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
16927 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
16928 dired.c's scmp function, had undefined behavior.
16929 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16930 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
16931 * buffer.h: ... to here, because these macros use current_buffer,
16932 and the new implementation with inline functions needs to have
16933 current_buffer in scope now, rather than later when the macros
16935 (downcase, upcase1): New static inline functions.
16936 (DOWNCASE, UPCASE1): Reimplement using these functions.
16937 This avoids undefined behavior in expressions like
16938 DOWNCASE (x) == DOWNCASE (y), which previously suffered
16939 from race conditions in accessing the global variables
16940 case_temp1 and case_temp2.
16941 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
16942 * lisp.h (case_temp1, case_temp2): Remove their decls.
16943 * character.h (ASCII_CHAR_P): Move from here ...
16944 * lisp.h: ... to here, so that the inline functions mentioned
16945 above can use them.
16947 * dired.c (directory_files_internal_unwind): Now static.
16949 * fileio.c (file_name_as_directory, directory_file_name):
16950 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
16952 (file_name_as_directory): Use const pointers when appropriate.
16953 (Fexpand_file_name): Likewise. In particular, newdir might
16954 point at constant storage, so make it a const pointer.
16955 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
16956 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
16958 (Fset_file_times, Finsert_file_contents, auto_save_error):
16959 Rename locals to avoid shadowing.
16961 * minibuf.c (choose_minibuf_frame_1): Now static.
16962 (Ftry_completion, Fall_completions): Rename or remove locals
16963 to avoid shadowing.
16965 * marker.c (bytepos_to_charpos): Remove; unused.

17389 is actually in tparam.c. The previous trick of using incompatible
17390 decls in different modules does not conform to the C standard.
17391 All callers of tparam changed to use tparam's actual API.
17392 * tparam.c (tparam1, tparam, tgoto):
17393 Use const pointers where appropriate.

17401 (turn_on_face, init_tty): Likewise.
17402 * termchar.h (struct tty_display_info): Likewise.
17404 * term.c (term_mouse_position): Rename local to avoid shadowing.
17406 * alloc.c (mark_ttys): Move decl from here ...
17407 * lisp.h (mark_ttys): ... to here, so that it's checked against defn.
